Description

[Detailed description of the invention] This invention relates to an opening/closing lid device for the casing of measuring instruments, electrical equipment, etc. In particular, it is used to store dry batteries, etc.
It is convenient to use at the point where it is taken out. below,
This idea will be explained.

FIGS. 1a and 1b are a side sectional view and a sectional view taken along the line X--X of the main parts of an embodiment of this invention. In these figures, 1 is a housing having an opening;
A is a chassis portion made of a metal plate, and 1B is a vinyl chloride sheet covering the outer surface of the chassis portion 1A. 2 shows the entire lid. Reference numeral 3 denotes the lid body of the lid 2, which is plate-shaped and made of vinyl chloride, etc., 4 is an auxiliary lid made of a metal plate and has an L-shaped cross section for opening and closing the lid 2, and 5 is the auxiliary lid of the auxiliary lid 4. A pin is integrally fixed to one end 4a by means such as screwing, 6 is a compression spring installed between the top 5a of the pin 5 and the lid body 3, and 7 is the pin 5.
The through holes 8A, 8B, and 8C are formed at one end 3a of the lid body 3 to allow the lid body 3 to pass therethrough, and the engagement grooves 8A, 8B, and 8C are engagement grooves formed on three sides of the inner surface of the opening of the housing 1 to engage the lid body 3. , 9 is a locking part formed on the sheet 1B on the side of the opening of the housing 1 to lock the other end 4b of the auxiliary lid 4, and is chamfered at about 45 degrees, and the tip is flat. has been done. Reference numeral 10 denotes an operating knob for opening and closing the lid 2.

Next, the operation of attaching the lid 2 to the housing 1 will be explained based on FIGS. 2a, b, and c.

First, in FIG. 2a, the other end 3 of the lid main body 3
b into the engagement grooves 8A and 8C, and then run in the direction of arrow A and insert the auxiliary lid 4 until the other end 4b comes close to the locking part 9.

Next, as shown in FIG.
It rotates around a as a fulcrum, and the other end 4b moves away from the locking part 9. At this time, since the pin 5 is in an inclined state with respect to the lid body 3, the compression spring 6 is pressed.

Next, as shown in FIG. The other end 4b of the auxiliary lid 4 is connected to the locking portion 9 of the housing 1.
1, and the state shown in FIG. 1a is reached, completing the installation of the lid 2. When removing the lid 2 from the housing 1, the operation described above may be reversed.

FIG. 3 also shows that the other end 4b of the auxiliary lid 4 is attached to the housing 1.
This shows another embodiment in which the portion that is locked is a stepped locking portion 11.

It goes without saying that the opening/closing lid device of this invention can be used not only for the above-mentioned measuring instruments, electrical equipment, etc., but also for other cases.

As explained above, this invention involves slidably engaging the plate-shaped lid body in the engagement groove formed on the inner side of the opening of the housing, and attaching the top portion to one end of the auxiliary lid having an L-shaped cross section. This pin is inserted into a through hole formed in one end of the lid body, and a compression spring is installed between the top of the pin and the lid body, so that the lid can be securely engaged with the housing. It has the advantage of being easy to open and close.

[Brief explanation of the drawing]

Figures 1a and b are a side sectional view and a cross-sectional view taken along line X-X of the main parts showing one embodiment of this invention, and Figures 2a and 2b are
b, c are explanatory diagrams showing the operation of attaching the lid to the housing;
FIG. 3 is a sectional view showing the shape of a stepped locking portion where the auxiliary lid locks. In the figure, 1 is the housing, 2 is the lid, 3 is the lid body, 4 is the auxiliary lid, 5 is the pin, 5a is the top, 6 is the compression spring, 7
8A, 8B, 8C are engagement grooves, 9 and 11 are locking portions, and 10 is a knob.

Claims (1)

[Scope of utility model registration request] The plate-shaped lid body is slidably engaged with the engagement groove formed on the inner side of the opening of the housing, and a pin having a top is fixed to one end of the auxiliary lid having an L-shaped cross section. An opening/closing lid device characterized in that a compression spring is inserted into a through hole formed at one end of the lid body and is installed between the top of the pin and the lid body.
