Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a locking tool used when locking a lid of a bag, and more specifically, it relates to a predetermined shape on a surface of a substrate. From a locking tool body A which is provided with a stand projectingly and a rotary locking body is pivotally mounted on the surface of the stand, and a locking plate B having an empty portion into which the stand and the rotary locking body are loosely inserted. The locking plate B is locked in the locking tool body A by changing the rotational position of the rotary locking member after the rotary locking member is penetrated from the empty portion of the locking plate B. It relates to the improvement of ingredients.

"Prior Art" Conventionally, the above-mentioned locking tool is widely used by being called "Hinelli", and normally, the base of the locking tool body A, the rotary locking body, and the empty portion of the locking plate B are used. Each have the same rectangular shape, and the locking plate B
A base and a rotation lock are loosely inserted in the empty space to be superposed on the surface of the lock body A, and the rotary lock body located above the surface of the lock plate B is rotated by 90 degrees or 45 degrees. Then, the locking plate B is locked by means of this, and in order to remove this locking, the rotation position of the rotary locking body is returned to a position compatible with the base, and the base and the rotary locking body are pulled out from the empty portion. The locking plate B is removed.

[Problems to be solved by the invention] However, when the above-described conventional locking device is engaged and disengaged, when locking is performed, an operation of overlapping the locking plate B with the locking device body A and rotation locking There are two operations, one is to rotate the body, and the other is to detach and release the lock, that is, the operation to rotate the rotary lock body and the operation to release the lock plate B from the lock body A. This operation is necessary and complicated, and in reality, the locking plate B is engaged by the attractive force of the permanent magnet without the operation of rotating the rotary locking body when locking. Those that are adsorbed to the stopper body A have also been proposed.

Further, as another problem, since this kind of locking device is designed to rotate by pinching the rotary locking body with a fingertip, the rotary locking body must be projected as much as a finger can be hooked, It has been pointed out that the height is high and the place of use is limited and the appearance is not good.

"Purpose" Therefore, the present invention has been made in view of the above, and an object thereof is to provide a locking tool which can be made thinner than conventional ones and which can be easily mounted and disengaged.

[Means for Solving Problems] In order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned utility model registration claim, has a table of a predetermined shape on the surface of the substrate in order to solve the above problems. A locking tool body A formed by projecting and pivotally mounting a rotary locking body on the surface of the base, and a locking plate B having an empty portion into which the base and the rotary locking body are loosely inserted, After the rotary locking body is penetrated from the empty portion of the locking plate B, the rotational position of the rotary locking body is changed to move the locking plate B to the locking tool body A.
The locking plate B is provided with a circular hollow portion 11, and a plurality of engaging members projecting toward the center of the circular hollow portion 11 are provided on the inner peripheral wall portion of the circular hollow portion 11. A stopper projection 12 is provided so as to project, and the locking tool body A has a plurality of cutouts 22 which fit the locking projection 12 on the outer periphery and can be loosely inserted into the circular hollow portion 11. A substrate 20 is provided on which a cylindrical base 21 having an outer peripheral shape is erected, a flexible arm 24 is projected from the substrate 20, and the flexible arm 24 is provided on the back side of the flexible arm 24 on the front side. A spring 25 for urging toward is housed, and a plurality of notches 32 that fit the locking projections 12 are provided on the outer peripheral portion of the cylindrical base 21 and the outer peripheral shape of the cylindrical base 21. The rotary locking body 30 having the same outer peripheral shape is inserted into the cylindrical base 21 through the shaft portion 31 protruding from the center of the back surface of the rotary locking body 30 to extend to the back surface side of the substrate 20 to be superposed. And then From shaft portion 31, an operation lever for rotating the rotary locking member 30
A spring 34 is provided to project the operation lever 34 and to urge the operation lever 34 toward the proximal end portion of the flexible arm 24 between the operation lever 34 and the spring receiver 27 provided on the back surface of the substrate 20. 28, and the tip of the flexible arm 24 is engaged with the operation lever 34 at a rotational position where the cutout 32 of the rotary locking body 30 matches the position of the cutout 22 of the tube base 21. Further, the engaging portion 33 is provided, and further, the flexible arm 24 is pushed down to the surface side portion of the intermediate portion of the flexible arm 24 which is located in the centrifugal direction from the outer periphery of the cylinder base 21. A protrusion (26) for detaching the engagement between the tip and the engaging portion (33) is provided in a protruding manner.
The technical means is characterized in that a cover 40 that penetrates 26 and 26 is attached.

[Operation] In the locking device of the present invention, it is assumed that the locking device main body A is attached to the bag main body and the locking plate B is attached to the bag lid. Then, the operation lever 34 is rotated to the position shown by the solid line in FIG.
Leave it locked at the tip of 24.

It is assumed that the notch 22 is loosely inserted into the inside 11 and the rotary locking body 30 completely penetrates to the surface side of the locking plate B (at least the surface side of the locking projection 12).

Then, due to the superposition of the locking plate B on the locking device body A, the back surface of the locking plate B pushes down the protrusion 26, so that the flexible arm 24 bends due to its flexibility. The engagement between the tip and the engaging portion 33 is released, and the operating lever 34 to the rotary locking body 30 are rotated by the urging force of the spring 28 to the position shown by the chain line in FIG. Then, in the circular empty portion 11 of the locking plate B, the cylinder stand
21 is loosely fitted, and the locking projection 12 is located in the cutout 22, so that the locking plate B cannot rotate, and the cutout of the rotary locking body 30 is located above the locking projection 12 upward. Since the large-diameter portion other than 32 is located, the locking plate B has the locking projection 12 with the rotary locking body 30.
It is locked so that it will not fall out. In addition, this rotation locking body
It is needless to say that a stopper is provided at an appropriate position in order for 30 to rotate to the rotational position shown by the chain line in FIG. 2 by the urging force of spring 28, but this point will be described later.

Then, to detach the locking plate B locked as described above, the operation lever 34 is rotated rightward in FIG. 2 against the biasing force of the spring 28. Then, the operation lever 34
2 returns to the position shown by the solid line in FIG. 2, and the tip of the flexible arm 24 is lifted by the urging force of the spring 25 and the tip of the flexible arm 24 engages with the engaging portion.
It engages with 33 and is fixed to a solid line position in the drawing. In this state, since the cutout 32 of the rotary locking body 30 matches the position of the cutout 22 of the tube base 21, the locking plate B is separated from the cylinder base 21 and the rotary locking body 30 to release the lock. can do. Since the flexible arm 24 is raised by the urging force of the spring 25, the protrusion 26 also protrudes, so that the spring 25 is locked by the locking plate B.
It also acts to push up.
