Description

[Detailed Description of the Invention] The present invention relates to an interlocking electric key with a small number of parts and a simple locking and releasing mechanism.

In an interlocking electric key that combines and interlocks a lock electric key and a release electric key, the conventional structure has the disadvantage that the interlocking operation is complicated and requires many types of parts.

In order to eliminate the above-mentioned drawbacks, an attempt is made to provide an interlocking electric key with a simple locking and releasing mechanism in which the lock button and the release button have the same structure, and which has fewer types of parts.

A detailed explanation will be given below according to the drawings.

Fig. 1 is a rear view of the present invention-embodiment, Fig. 2 is an exploded view of the same,
FIG. 3 shows a longitudinal sectional view A-B of the same.

la and lb are push buttons of the same structure, 1a is a lock button, 1b
is the release button.

2 a and 2 b are side plates, 3 is an upper mounting plate, 4 is a lower mounting plate, and 5 and 6 are interlocking plates and release cam plates according to the present invention.

7 is a recovery spring for the push button, and 8 is a recovery spring for the interlocking plate.

The push buttons 1a and 1b are molded parts and are integrated with a lever 23, a cam pin 11, and a button body 24 having a groove 25 for accommodating a contact piece 26, and a hole 33 for accommodating a screw 7 at the bottom.
have.

Although the cam pin 11 is press-fitted into the button body 24, it may be molded integrally with the button body 24.

The lever 23 is inserted into the hole 18 of the upper mounting plate 3 to move up and down, and the pushbutton return lever 7 is positioned by a convex portion 28 provided on the lower mounting plate 4.

The push buttons 1a and lb are attached to the upper and lower mounting plates 3.
, 4, and the interlocking plate 5 is slidably supported between the side plates 2a and 2b together with a spring 8.

That is, the ears 19 of the upper and lower mounting plates 3 and 4 are connected to the side plates 2a.
, 2b and fixed by twisting or the like,
The engaging portion 21 of the interlocking plate 5 is configured to freely slide within the holes 22 of the side plates 2a, 2b.

The support arm of the lower mounting plate 4 engages with the stepped portion 27 of the button body 24, and serves as a guide for the vertical movement of the push buttons 1a, lb.

Reference numeral 13 denotes a terminal plate to which a fixed contact piece 15 having a terminal 44 is press-fitted and fixed.

The notch 16 of the terminal plate 13 is fitted into and fixed to the projections 17 of the upper and lower mounting plates 3 and 4.

The movable contact piece 26 is supported within the groove 26 and elastically clamps the fixed contact 15.

If you press the lock button 1a now, the cam pin 11 will move to the interlocking plate 5.
When the inclined part 30 is pushed and the interlocking plate 5 is moved to the left and the amount of depression is increased, the cam pin 11 enters the jaw part 31 and returns to IF3! The interlocking plate 5 is returned and locked by the force of the spring 8.

During this time, the movable contact piece 26 is lowered by the lowering of the button body 24, and the short circuit combination of the fixed contact pieces 15 is changed.

When another lock button 1a is pressed, the interlocking plate 5 moves to the left by the interlocking plate inclined portion 30 at that position, releasing the previously locked button and locking itself.

Next, the cancellation will be explained.

The release cam plate 6 is rotatably supported together with the release spring 10 in the hole 32 of the interlocking plate 5 by the release pin 9, and one end 38 of the release spring 10 is locked to a corner 37 of the protrusion 34 of the interlocking plate 5, and the other end is engaged with the upper arm 40 of the release cam plate 6, and presses the lower 36 surface of the release cam plate 6 against the 35 surface of the protrusion 34.

Therefore, the release cam plate 6 can be rotated clockwise, but
It does not rotate counterclockwise.

The release cam upper arm 40 has a bent inclined portion 41,
When the release button 1b is pressed, the cam pin 11 presses the inclined portion 41, and the release cam plate 6 rotates clockwise, but the interlocking plate 5
has no effect on

When the amount of depression is increased, the cam pin 11 moves toward the end 42 of the inclined portion 41.
, the release cam plate 6 returns to its previous position due to the force of the release spring 10, and when the button is released, the cam pin 11 now passes through the back side 43 of the inclined portion 41 and rises.

At this time, since the release cam plate 6 cannot rotate counterclockwise as described above, the interlocking plate 5 is moved to the left by the amount of inclination.

Therefore, the locked lock button 1a is released and restored.

As described above, according to the present invention, the lock button and the release button can be made to have the same structure, making it suitable for molding, simplifying the locking and releasing mechanisms, and providing an interlocking electric key with fewer types of parts.

[Brief explanation of the drawing]

FIG. 1 is a rear view of an embodiment of the present invention, FIG. 2 is an exploded view of the same, and FIG. 3 is a longitudinal sectional view A-B of the same. la and lb are the push buttons, 2 a and 2 b are the side plates, 3 is the upper mounting plate, 4 is the lower mounting plate, 5 is the interlocking plate, 6 is the release cam plate, 7 is the push button return plate, and 8 is the push button. As for the parts of the interlocking plate, 9 is a release pin, 10 is a release spring, and 11 is a cam pin.

Claims (1)

[Scope of utility model registration request] In an interlocking electric key having a plurality of lock buttons and at least one release button for releasing the lock buttons, sloped portions and jaw portions for locking the lock buttons are provided at multiple locations corresponding to the lock buttons. An interlocking plate is movably disposed on the side surface of the lock button, a cam plate is rotatably supported by the interlocking plate, and one end of the cam plate is attached to the interlocking plate by an elastic spring. A slanted part is pressed against the protrusion and bent at the other end, and when the release button is pressed, a cam pin provided on the button engages with the slanted part and rotates the cam plate, thereby restoring the release button. Sometimes the cam pin engages with the surface of the inclined part to move the interlocking plate and release the lock button, whereby the lock button has a cam pin for locking and the release button has a cam pin for release. An interlocking electric key characterized in that it is possible to use the same configuration as the above.
