[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 7 FIG. 1 is a first embodiment of the present invention, which provides a lock with a protective structure, including a lock 1, a protective structure 2 disposed inside the lock 1, and a reset assembly 3 disposed between the protective structure 2 and the lock 1;

[0027] The protective structure 2 includes a movable plate 201, the outer surface of which is movably connected to the inner wall of the lock 1. Protective plates 203 are provided on both sides of the inner cavity of the movable plate 201, and an oblique groove 205 is provided on the outer side of the protective plate 203.

[0028] The reset assembly 3 includes a connecting plate 301, which is arranged on the back of the movable plate 201. A chute 305 is provided inside the movable plate 201. A slider 306 is movably connected to the chute 305. The back of the slider 306 extends into the inner cavity of the connecting plate 301.

[0029] When the operator unlocks the lock 1, the key is placed against the inclined groove 205 on the protective plate 203. The key will squeeze the protective plate 203 through the inclined surface on the inclined groove 205, driving the protective plate 203 to move to both sides. Then the operator turns the key to unlock the lock 1, and at the same time drives the protective structure 2 to rotate as a whole. Then, the movable plate 201 drives the slider 306 to move inside the reset component 3, and the reset component 3 resets the rotated protective structure 2 as a whole, making it convenient for subsequent unlocking of the lock 1, thereby opening the protective structure 2 by squeezing, and there is no need to manually lift the protective plate 203. The operation is more convenient and convenient for personnel to unlock.

[0030] Example 2

[0031] like Figure 2 and Figure 4 As shown, this embodiment includes the features of the embodiment 1, and the distinguishing technical features are that the lock 1 includes a lock body 101, a lock core 103 is provided inside the lock body 101, and a handle 102 is provided on the front of the lock body 101;

[0032] By inserting a key into the lock core 103 and then rotating the lock core 103 , the fixation between the lock body 101 and the door frame is released.

[0033] The outer side of the protective plate 203 is connected to a spring piece 204, and the other end of the spring piece 204 is connected to the inner wall of the movable plate 201;

[0034] When the operator squeezes the key to move the protective plate 203 to both sides, the spring piece 204 is in an extruded state, which will apply outward pressure to the protective plate 203, driving the protective plate 203 to reset inward. Therefore, when the key is pulled out from the lock cylinder 103, the protective plate 203 is reset to protect the outside of the lock cylinder 103 and prevent dust or impurities from entering the interior of the lock cylinder 103.

[0035] The inner cavity of the movable plate 201 is provided with a limiting rod 202, and the outer surface of the limiting rod 202 is movably connected to the inner wall of the protective plate 203;

[0036] When the protective plate 203 is squeezed by the key, the protective plate 203 is driven to move on the limiting rod 202 through the inclined slot 205 , and the limiting rod 202 is used to prevent the protective plate 203 from positional displacement.

[0037] Example 3

[0038] like Figures 4 to 7 As shown, this embodiment includes the features of embodiment 1, and the distinguishing technical features are that a limit ring 302 is provided in the inner cavity of the connecting plate 301, and the outer surface of the slider 306 is movably connected to the inner wall of the connecting plate 301;

[0039] When the key is inserted into the lock core 103 and rotated, the key drives the movable plate 201 to rotate as a whole. As the movable plate 201 rotates, the slider 306 moves in the inner cavity of the connecting plate 301 and moves along the trajectory of the limiting ring 302.

[0040] The outer surface of the limiting ring 302 is provided with movable blocks 303 located on both sides of the slider 306, and the inner side of the movable block 303 is movably connected to the outer surface of the slider 306;

[0041] When the movable plate 201 rotates, the movable plate 201 drives the slider 306 to push the movable block 303 , and then pushes the movable block 303 to a suitable position for locking or unlocking the lock 1 .

[0042] Among them, a spring 304 is provided on the outer side of the movable block 303, and the other end of the spring 304 is connected to the inner wall of the connecting plate 301;

[0043] When the lock cylinder 103 is unlocked, the key is pulled out of the lock cylinder 103, and the movable block 303 and the slider 306 are reset by the elastic force of the spring 304, so that the protective plate 203 can be reset to any position, and the lock cylinder 103 can be continuously protected by the protective plate 203, while the operator can easily insert the key.

[0044] The working principle and use process of this utility model:

[0045] First, when the operator wants to unlock the lock 1, he puts the key against the inclined groove 205 of the protective plate 203, and squeezes the protective plate 203 with force, driving the protective plate 203 to move on the outer surface of the limit rod 202, thereby limiting the position of the limit rod 202 to prevent position deviation during movement. Then, the key is inserted into the lock cylinder 103, and then the lock cylinder 103 is rotated to drive the movable plate 201 to rotate as a whole. The slider 306 on the movable plate 201 moves along the inner cavity of the connecting plate 301, squeezing the movable block 303 on one side. With continuous rotation, the lock 1 is unlocked. When the key is removed from the lock cylinder 10 When the key 3 is pulled out, the elastic force of the spring 304 drives the movable block 303 and the slider 306 to reset, keeping the protective plate 203 on the movable plate 201 in a vertical position, making it convenient for the key to open the protective plate 203. At the same time, the elastic force of the spring 204 drives the protective plate 203 to reset, so that the lock cylinder 103 can continue to be protected, preventing external dust or impurities from entering the lock cylinder 103 and avoiding damage to the lock cylinder 103. The design of the protective plate 203 makes it convenient for personnel to unlock the lock 1, without having to manually hold the protective plate 203, which brings convenience to the use of the lock 1.
