Detailed Description

As shown in fig. 1, a safety lock, including base 1 and the rectangular shape lock axle 2 that is disk-shaped, both ends are equipped with bellied carrier block 11 respectively around on base 1, arc 12 has all been seted up on two carrier block 11, both ends are located two arc 12 respectively around the lock axle 2, and be equipped with annular arch 21 on the outer peripheral face of lock axle 2 front end, annular arch 21 supports with the carrier block 11 formation of base 1 front end and leans on, all be equipped with bellied dog 13 on the base 1 of lock axle 2 both sides, still be equipped with on the outer peripheral face of lock axle 2 and lean on the lug 22 of limiting lock axle 2 axial pivoted with dog 13, still be equipped with elastic element 3 on the lock axle 2 and lug 22 and remain the trend of leaning on dog 13 all the time under the effect of elastic element 3 elasticity, lock axle 2 front end still is equipped with the head 23 of keeping out of curvature down.

Preferably, the elastic element 3 includes a spring sleeve 31 disposed on the lock shaft 2, the spring sleeve 31 is circumferentially fixed to the lock shaft 2, the lock shaft 2 can slide axially relative to the spring sleeve 31, and the spring 32 is disposed outside the spring sleeve 31 and exerts an elastic force on the spring sleeve 31.

Preferably, the spring sleeve 31 is provided with a convex abutting portion 311 in the circumferential direction, one end of the spring 32 abuts against the latch 24, and the other end abuts against the base 1.

Preferably, a clamping groove 312 is formed in the inner circumferential surface of the spring sleeve 31, a clamping block 24 clamped with the clamping groove 312 is arranged on the lock shaft 2, and the lock shaft 2 and the spring sleeve 31 are circumferentially fixed through clamping of the clamping block 24 and the clamping groove 312.

Preferably, the base 1 is further provided with a raised limiting portion 14, the limiting portion 14 and the locking block 24 form a stop to limit the displacement of the lock shaft 2 towards the rear end of the base 1, and when the lock shaft 2 is rotated circumferentially, the stop of the limiting portion 14 and the locking block 24 can be released.

Preferably, the device further comprises a shell 4, wherein the shell 4 is hemispherical and is detachably connected to the upper end face of the base 1.

Preferably, the lower end face of the base 1 is also provided with a double-faced adhesive

Firstly, as shown in fig. 1, the spring 32 is sleeved on the spring sleeve 31, the bent portion at the right end of the spring 32 locks the protruding resisting portion 311 on the spring sleeve 31 to prevent the spring 32 from rotating counterclockwise under normal conditions, then the spring sleeve 31 with the spring 32 is sleeved on the lock shaft 2 with the position of the clamping groove 312 on the spring sleeve facing the position of the clamping block 24 of the lock shaft 2, next, the assembled lock shaft 2 is placed on the base 1, when the spring sleeve is placed, the protruded portion at the bent right end of the lock shaft 2 is perpendicular to the inward bending direction of the base 1, the spring 32 foot protruded from the left end of the spring 32 on the lock shaft 2 is clamped on the base 1, the locking shaft 2 is pressed to clamp the outer shell 4, and finally, a double-sided adhesive tape patch is pasted, and the installation is completed.

Locking principle: the safety lock is attached to the side edge of the drawer cabinet, the stopping head 23 of the safety lock is used for hanging the drawer, and the drawer is in a locked state. After the lock shaft 2 is installed on the base 1, because the protruding fixture block 24 on the lock shaft 2 is inserted into the fixture groove 312 on the inner side of the spring sleeve 31, the lock shaft 2 is in relation to the spring sleeve 31, the spring sleeve 31 can only rotate along the axis along with the lock shaft 2, when the lock shaft 2 moves left and right, the spring sleeve 31 is clamped by the fixture groove 312 at the bottom so that the spring sleeve 31 cannot move left and right along with the lock shaft 2, and when the lock shaft 2 is normally locked, the spring 32 has clockwise acting force on the lock shaft 2, so that the lock shaft 2 is not always in a state that the hook is hooked on the drawer under the condition of manual operation.

Opening principle: manually rotating the lock shaft 2 by 90 degrees anticlockwise, then pushing the lock shaft 2 inwards to enable the fixture block 24 protruding from the lock shaft 2 to be inserted into the fixture groove 312, so that the lock shaft cannot rotate, and the hook is in a state of not hanging the drawer at this time, namely, an open state; and locking again, the rear end of the lock shaft 2 is pressed down to enable the clamping block 24 protruding from the lock shaft 2 to be separated from the clamping groove 312, the lock shaft 2 automatically rotates clockwise for 90 degrees to be clamped under the clockwise acting force of the spring 32, and the hook of the lock shaft 2 is in a state of hanging the drawer at this time, namely in a locked state.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
