Description

[Detailed Description of the Invention] (Industrial field of application) The present invention arranges test tubes containing samples for serum cold storage or blood and various other tests, and keeps the tube cold, stirs, and prevents germs. The present invention relates to a test tube stand case with a lid for medical and analysis, which is closed with an opening / closing lid for such purposes.

(Prior Art) A conventional test tube stand case with a lid, in which the internal state of a series of test tube groups can be seen from the outside, is disclosed in Japanese Utility Model Publication No. 59-20.
Although there is a product of No. 348, the opening / closing lid mechanism corresponding to the test tube of different height of this conventional product has vertical frames arranged side by side on both side plates of the case body, and horizontal parallel teeth are engraved between them. The parallel teeth that mesh with the parallel teeth on the case body side are engraved on the inner surface of the leg piece of the one-piece resin plate that is vertically installed so as to be guided between the vertical frames on the side surface of the lid plate, Since the lid is opened and closed by engaging or disengaging the parallel teeth of both legs of the lid plate with the parallel teeth on the case body side, this lid opening and closing grips the lower ends of both resin leg legs of one plate. Then, the spring opening operation is performed from below toward the forcibly outward direction.Therefore, the spring resistance from the bottom is very large at the root of the resin leg piece, and the root is broken. It is easy and lacks safety and long-term usability. , But easy to be broken with the lid open and close at the normal temperature,
Since this article is often used for cold storage, there is a drawback that the breakage rate is significantly high under the cold storage condition.

(Problems to be solved by the invention) The present invention eliminates the above-mentioned drawbacks of the conventional product, and there is no danger of breaking the leg of the opening / closing lid of this product at room temperature or in a cold condition, and the lid can be opened and closed safely and securely. The purpose is to provide a product that can be manufactured, has long-term usability, and has high commercial value.

(Means for Solving the Problem) A supporting flat plate shelf in which holes for arranging test tube groups are arranged, a plastic case body related to the composition of the bottom and both side plates, and a cover plate for covering the upper surface of the case body. The outer surface of both side plates of the case body, the vertical installation at a required interval of a pair of vertical frames with opposing teeth engraved on the opposite inner side, and both side surfaces of the lid plate, A pair of split leg lever mechanisms with a handle piece, in which a tooth fitting between the vertical frames and meshing with the facing tooth are engraved in the lower part of each outer side and an opening spring is installed between the inner facing sides, Each of them has a structure in which the upper end portions thereof are pivotally attached and hung vertically.

(Function) The split leg lever mechanism is pivotally attached to both sides of the cover plate and fitted between the vertical frames of the case body. When the open spring is contracted toward the inside, it is pivotally tilted, and it is inserted smoothly between the vertical frames with the lid, and when the closed state is decided, when you release your finger from the handle, the open spring By the force, the teeth open outwardly to the left and right, and the teeth on each outer side are pressed against the opposed teeth on the vertical frame to form a positive mesh and secure the closed lid.

Next, as described above, by pushing the handle piece inward, the lever mechanism pivots inward to disengage the mesh, and by holding the handle piece and lifting the lever mechanism, the lid is opened.

(Embodiment) The present invention relates to a test tube stand case with a lid that allows the internal state of a test tube group containing samples for serial cold storage or other various tests to be seen from the outside. An example will be described with reference to the drawings as follows.

The case body a in FIGS. 1 and 2 is made of a transparent plastic, and it has one or several stages of the same outer shape having a fixed arrangement of holes (2) for connecting the test tube (1) group in series. A flat plate shelf (3), a bottom (4) having the same outer shape as that of the shelf (3), and a bottom (4) fixed horizontally between the lower ends of the shelf (3) with a space above the bottom (4). ) Horizontally fixed at least a pair of side plates (5) (5) ′
And composition. The side plates (5) (5) 'may be made of an opaque resin material, and in this embodiment, the two shelves are placed above the bottom (4).
Although (3) is fixed in two steps, the number of steps of the shelf (3) may be one step when the height of the test tube (1) is low, or when it is high, it corresponds to the height. It is the required number of stages.

In addition, the cover plate b which covers the case body a toward the upper surface is
It is made of the same material as the case body a, is provided with a downward peripheral side portion (6), and on the back side is a plastic sponge or a rubber cushion plate (7) suitable for pressing and closing the tube mouth of the test tube (1). It is fitted.

According to the present invention, the opposite teeth (9) (9) are provided on the opposite inner sides (8) (8) 'with respect to the symmetrical portions at the central portions of the outer surfaces of the both side plates (5) (5)' of the case body a. A pair of vertical frames (10) (10) 'formed by engraving ′ are arranged in parallel at a required interval. Then, the split leg lever mechanism of FIG. 3 is provided on both sides of the peripheral side portion (6) of the cover plate b. That is, the teeth (11) (11) 'fitted between the vertical frames (10) (10)' of the case body a and meshing with the opposed teeth (9) (9) 'are formed on the lower portions of the outer sides. And the handle pieces (1
2) (12) ′ is provided and facing projections are provided on each facing inner side of the lower part.
(13) (13) 'is provided, and the opening spring (1
4) (14) 'is fitted and erected so that the split leg levers (15) (15)', which are spaced apart from each other, are screwed (16) ( 16) ′ is provided so as to be vertically installed by being pivotally attached to the peripheral side portion (6).

When the levers (15) and (15) 'are pivotally attached to each other, the seat plate (17) is, if necessary, reinforced so as to reinforce the pivotally attached portion.
(17) 'may be adhered to the peripheral side portion (6), but depending on the thickness and width of the peripheral side portion (6), the seat plate (17) (1
7) 'becomes unnecessary.

The levers (15) and (15) 'are made of hard resin or metal plate. Further, as the opening springs (14) (14) ', the illustrated coil spring is suitable.

The split leg lever (15) (1
5) ', the teeth (11) (11)' on the outer side are engaged and disengaged with the opposing teeth (11) (11) 'of the vertical frame (10) (10)' and are opened by spring force. In this case, the design is not limited to the illustrated form as long as the lever shape and the pivotal design are such that the inner upper ends of the two come into contact with each other and are regulated at a predetermined opening angle. Further, the vertical frames (10) (10) 'may be arranged in parallel at a plurality of places depending on the size of the case body a. In this case, the split leg levers (15 ) (1
5) ′ is naturally the corresponding number.

The present invention has the above-mentioned configuration and has a supporting flat plate shelf for the case body a.
The internal state of the test tube (1) group aligned in the hole (2) of (3) can be known from the outside, and the lid plate b is attached from above the case body a, and both side plates (5) and (5) of the case body a. The split leg levers (15), (15) 'are squeezed inward between the vertical frames (10), (10)' of the ′ to be fitted and inserted to cover the lid.

It is the handle piece (12) (12) ′ of each split leg lever (15) (15) ′.
By pushing the lever inwardly with a finger to tilt the levers (15) and (15) ′ inwardly about the pivotal attachment portion of the upper end so as to form a recess, thereby making the vertical frame (10) (10) 'Between the lever (15)
When (15) 'is fitted and the cover plate b is pressed from above, the tube plate of the test tube (1) group is pressed and closed by the cushion plate (7) provided on the back side, and the closed state is obtained.

When the lid is released, when the fingers are released from the handle pieces (12) (12) ', the levers (15), (15)' are rotated by the spring force of the opening springs (14), (14) '. It will open to the left and right around the attachment part toward the vertical frame (10) (10) ', and as a result, the teeth (11) on each outer side will be opened.
(11) 'is pressed against the opposed teeth (9) (9)' of the vertical frame (10) (10) 'to form a positive mesh, and the lid plate b is fixed to the lid firmly. Becomes

Next, when opening the lid, push the handle pieces (12) (12) 'inward with your fingers, and the levers (15) (15)' will be spring-pivoted into a recessed shape as described above. Then, the mesh is disengaged and the handle piece (12)
By lifting the lever mechanism by holding the (12) ', the levers (15), (15)' are detached from between the vertical frames (10), (10) 'and the lid is easily opened.

The spring opening of the split leg levers (15), (15) 'that are opened is regulated at a predetermined opening angle with their inner upper ends contacting each other.

In short, a split leg lever (15) (1
5) ′ springs open and close to each other between the vertical frames (10) and (10) ′ with respect to the pivotal joint, and the opposing teeth of the vertical frames (10) and (10) ′
(9) Since it is a mechanism that engages and disengages with respect to (9) ', there is no danger of breaking the leg because the spring pressure is not applied to the leg mounting part.

(Effect) As described above, according to the present invention, the split leg levers (15) and (15) 'according to the division pivotally mounted vertically on the cover plate b are spring-opened and closed to the left and right with the pivotal portion as the center. Therefore, unlike the forcible spring-opening leg that is directed outwards in the conventional single plate leg, as a result of no spring pressure or unreasonable external pressure being applied to the pivot part, the risk of breakage of the lid plate leg is at room temperature. Of course, even under any severe cold storage conditions, there will be nothing, and it will be possible to open and close the lid completely and surely, and long-term usability is guaranteed and a product with high commercial value is provided.

In addition, since the conventional one-piece lid plate leg does not open outward forcefully, the springiness of the root part of the leg becomes easy to loosen due to long-term use, and looseness easily occurs in the engagement between parallel teeth. In contrast to the risk of indefinite closure of the lid, this product uses the spring force of the open springs (14) (14) ′ that are installed to the levers (15) (15) ′.
Spring open to the left and right between the vertical frames (10) (10) ′,
The teeth (11) (11) 'push against the opposite teeth (9) (9)' of (0) (10) 'from the side to engage with each other, so spring relaxation does not easily occur and long-term It guarantees a close and secure closure of the mesh,
Opening and closing the levers (15), (15) 'in relation to each other to the left and right need only be done by pushing or releasing the handle pieces (12), (12)'. Has the effect of being easy to handle.
