reset spring

5, 6, push slider 7, 8 respectively downwards and reset.

The lock shell 1 is provided with a lock shell hole 1-1, and a lock handle square shaft 2-2 of the lock handle 2 penetrates through the lock shell hole 1-1.

A door lock handle groove 2-1 is formed in the door lock handle square shaft 2-2, a clamp spring 3 is clamped after the door lock handle groove 2-1 penetrates through the lock shell hole 1-1, and the clamp spring 3 plays a limiting role in the door lock handle 2;

in the installation process, after the square shaft 2-2 of the door lock handle penetrates through the lock shell hole 1-1, the clamp spring 3 is clamped in the groove 2-1 of the door lock handle, the outer diameter of the clamp spring 3 is larger than the inner diameter of the lock shell hole 1-1, and the clamp spring limits the position of the door lock handle 2 on the lock shell 1.

Then, the door lock handle square shaft 2-2 penetrates through the lock shell hole 1-1 and then is connected with a cam 4;

the cam 4 is provided with a cam square hole 4-3, and the door lock handle square shaft 2-2 penetrates through the lock shell hole 1-1 and then is inserted into the cam square hole 4-3; the square is not limited to the square, and any structure which can realize the limit in the rotating process and realize synchronous rotation can be adopted, such as a polygon and the like;

referring to fig. 1, the lock case 1 above the lock case hole 1-1 is provided with lock case grooves 1-2, 1-3, two

return springs

5, 6 are respectively arranged in the two lock case grooves 1-2, 1-3,

the return springs 5, 6 can slide in the corresponding lock housing grooves 1-2, 1-3.

Referring to fig. 3, a cover plate 9 is further provided, a screw 10 passes through a screw hole 9-1 of the cover plate 9 and then is connected to the lock case 1, and cover plate limiting ends 9-3 and 9-4 are arranged on two sides of the lower end of the cover plate 9; the cover plate 9 covers the shell groove 1-2 and the spring in a blocking manner, so that the offsetting and falling of the reset springs 5 and 6 and the sliders 7 and 8 are avoided.

Fig. 2 is combined with fig. 3, when the cover plate 9 is arranged outside the grooves 1-2, 1-3 of the lock shell, the limiting ends 9-3, 9-4 of the cover plate are respectively positioned above the two convex wings 4-1, 4-2, and the outer side surfaces of the two convex wings 4-1, 4-2 are protruded out of the outer side surfaces of the two sliding blocks 7, 8;

therefore, when the cam 4 rotates, the two convex wings 4-1 and 4-2 can respectively abut against the corresponding cover plate limiting ends 9-3 and 9-4, as shown in fig. 2, after the cover plate 9 is installed, the cam 4 rotates clockwise, the convex wing 4-1 rotates upwards, after the convex wing 4-1 rotates for a certain angle, the convex wing 4-1 abuts against the lower end of the cover plate limiting end 9-4, and at the moment, the cam 4 cannot rotate clockwise continuously; and rotating anticlockwise for the same reason.

The lower parts of the sliding blocks 7 and 8 are respectively provided with sliding block grooves 7-1 and 8-1, and the lower parts of the two upper reset springs 5 and 6 are positioned in the sliding block grooves 7-1 and 8-1, so that the reset springs 5 and 6 and the sliding block grooves 7-1 and 8-1 can better deviate in the length direction;

the lock shell 1 is provided with limiting parts 1-6 and 1-7, the sliding block 8 is provided with a sliding block limiting part 8-2, and the sliding block 7 is provided with a sliding block limiting part 7-2; when the sliding blocks 7 and 8 move downwards, the sliding block limiting part 8-2 can abut against the limiting parts 1-6, the sliding block limiting part 7-2 can abut against the limiting parts 1-7, and therefore the limiting parts 1-6 and 1-7 are used for the distance of downward movement of the sliding blocks 7 and 8.

The cam 1 is of a convex-like structure, and the edge of the convex-like structure is arc-shaped, so that the cam 4 can rotate better.
