The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 to 3, the back locking mechanism in this embodiment includes: the anti-lock knob comprises an anti-lock knob 1, a knob cover 2 and a return spring 3. Wherein, the outer end of the back locking knob 1 is arranged in the assembling hole 5 on the lock panel 4 in a penetrating way, and the inner side end of the back locking knob 1 is connected with the back locking bolt of the lock through the connecting mechanism. The back locking can be realized or the back locking can be released by rotating the back locking knob, and the specific structure that the back locking knob 1 is connected with the back locking bolt through the connecting structure is the prior art and is irrelevant to the innovation point of the application, and is not repeated herein.
The knob cover 2 is also arranged in the assembly hole 5 in a penetrating way and sleeved on the back locking knob 1, can synchronously rotate with the back locking knob 1 and can slide along the length direction of the back locking knob 1. The inside of the knob cover 2 is provided with a limiting structure 6 along the radial direction to prevent the knob cover 2 from sliding to the outside of the lock panel 4.
The reset spring 3 is arranged between the knob cover 2 and the inner wall of the lock, one end of the reset spring is abutted against the inner wall of the knob cover 2, the other end of the reset spring is abutted against the inner wall of the lock shell 7, and the reset spring 3 is in a force storage state, so that an acting force towards one side of the lock panel 4 is applied to the knob cover 2. The other end of the return spring 3 can also be abutted against any fixed side wall in the lock as a fixed end, for example, an annular fixed plate is arranged on the back locking knob 1, and the other end of the return spring 3 is abutted against the fixed plate, so that the function of the rebound knob cover 2 can be also realized.
The reset spring 3 in the back locking mechanism drives the knob cover 2 to move outwards and covers the knob part 9 of the back locking knob 1, so that the back locking caused by the touch of children can be prevented, and the back locking knob can be prevented from being rotated through a cat eye from the outer side of a door. When the back locking is needed or the back locking is released, the knob cover 2 is pressed inwards to expose the back locking knob 1, and then the back locking knob 1 is rotated.
Specifically, as shown in fig. 3, in this embodiment, the outer end surface of the anti-lock knob 1 is flush with the outer end surface of the knob cover 2, and when the anti-lock knob 1 needs to be rotated, the knob cover 2 is pressed inward, so that the knob portion 9 of the anti-lock knob 1 is exposed. In other embodiments, the outer end surface of the anti-lock knob 1 may also be located inside the outer end surface of the knob cover 2, and it is only necessary to ensure that the knob portion of the anti-lock knob 1 can be exposed when the knob cover 2 is pressed inward, and this structure needs to press the knob cover 2 inward for a long distance, which may further prevent children from touching and causing anti-lock. Or, the outer end face of the back locking knob 1 is set to be beyond the outer end face of the knob cover 2, but the beyond distance is smaller than 5mm, so that a user can know the position of the back locking knob 1 conveniently, and meanwhile, the exposed size is small, so that the back locking knob 1 can be prevented from being touched by children by mistake and being rotated.
In addition, in this embodiment, the outer end surface of the knob cover 2 is flush with the surface of the lock body panel 4, which not only can play a role of hiding the back locking knob 1, but also can make the surface of the inner side of the door of the lock smooth and beautiful. Of course, in other embodiments, the outer end face of the knob cover 2 may be disposed beyond the outer surface of the lock body panel 4, and may also serve to conceal the anti-lock knob 1.
Since the knob cover 2 needs to be rotated in the fitting hole 5, both the knob cover 2 and the fitting hole 5 are formed in a circular shape. Since the knob portion 9 of the lock knob 1 needs to be rotated in synchronization with the knob cover 2 and the knob cover 2 needs to be slid in the longitudinal direction of the lock knob 1, the knob portion 9 is formed as a long straight column and has a non-circular cross-sectional shape.
It should be noted that the fitting hole 5 also functions to restrict the knob cover 2 from moving in the radial direction, and therefore, the outer end face of the knob cover 2 should always be outside the inner side face of the fitting hole 5 when the knob cover 2 is slid on the inner side. For this reason, the knob cover 2 may be slidable inward by a distance smaller than the length of the fitting hole 5. Or, the boss 8 protruding towards the inner side of the lock is arranged on the inner side of the assembly hole 5, so that when the knob cover 2 slides towards the inner side, the outer end face of the knob cover is always positioned on the outer side of the end face of the boss 8, the sliding distance of the knob cover 2 towards the inner side is increased, and the knob cover 2 can be limited to move along the radial direction.
In addition, the function of the return spring 3 is to press the knob cover 2 against the outermost end, so in this embodiment, the return spring 3 is sleeved outside the anti-lock knob 1 and is not in contact with the anti-lock knob 1.
In this embodiment, the stopper structure 6 is an annular protrusion protruding in the radial direction of the knob cover 2, and when the knob cover 2 is slid outward by the biasing force of the return spring 3, the stopper structure 6 abuts against the inner end surface of the fitting hole 5, so that the knob cover 2 can be prevented from sliding out of the fitting hole 5. Of course, the stopper structure 6 may be provided with a plurality of protrusions protruding in the radial direction of the knob cover 2, and the above-described effects can be similarly obtained.
In addition, the embodiment also discloses a lock, which applies the back locking mechanism, wherein the back end of the back locking knob 1 is connected with the back locking bolt of the lock, and when the back locking knob 1 is rotated, the back locking bolt can be driven to extend out or retract, so that the back locking is realized or the back locking is released.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
