[0028] The structure and principle of the present application are very clear to the people in this profession. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] As shown in Figure 1 , 2 , 3, the anti-misoperation anti-theft lock of the present application comprises a lock body, a guide body, an adjusting piece and an anti-theft device. As shown in Figure 3 , the lock body is provided with guide grooves on both sides, and a plurality of adjusting tooth grooves are formed in the bottom of the lock body, and the two sides of the adjusting tooth grooves are sawtooth structures.

[0030] As shown in Figure 3 , 4 , 5, the adjusting piece comprises an adjusting piece base, a sawtooth connection structure arranged above the adjusting piece base and a stop block arranged above the sawtooth connection structure. The two sides of the sawtooth connection structure of the adjusting piece are provided with sawtooth structures, which are connected with the adjusting tooth grooves, and are used to adjust the position of the adjusting piece relative to the adjusting tooth grooves.

[0031] As shown in Figure 3 , the guide body is arranged in the lock body and is connected with the guide groove of the lock body, one side of the guide body is provided with a lock tongue, a recess is formed in the upper part of the guide body, the recess forms a handle, the handle and the lock tongue are an integral structure, the lower part of the guide body away from the lock tongue is a step structure, the step structure of the guide body is connected with the lock body through an elastic body, a cavity is arranged in the lock tongue, a first slot is formed in the upper part of the lock tongue, a second slot is formed in the side of the lock tongue close to the recess of the handle, a protrusion is arranged in the bottom of the guide body, and the protrusion is connected with the stop block of the adjusting piece. The cavity of the lock tongue is further provided with an anti-friction lock tongue insert.

[0032] As shown in Figure 3 , 6As shown, the anti-theft device is provided with a button at one end and an anti-theft hook at the other end. The button and the anti-theft hook are connected through a connecting plate, which is arranged in the cavity of the lock tongue. The anti-theft hook extends from the first slot of the lock tongue, and the button extends from the second slot of the lock tongue. The bottom of the anti-theft device is connected with the cavity of the lock tongue through an elastic body. The guiding body groove is provided with a cover plate away from the side of the lock tongue. The cover plate extends to the outside of the guiding body and forms an avoidance with the lock body.

[0033] By adjusting the position of the adjusting member in the adjusting tooth groove, the length of the lock tongue extending out can be controlled. Because the elastic body pushes the guiding body forward, and because the bottom of the guiding body is provided with a protrusion, the protrusion cooperates with the stop block of the adjusting member, so that the guiding body is stopped by the stop block. Therefore Figure 8 The length of the lock tongue extending out in the state is 8mm. By adjusting the position of the adjusting member in the adjusting tooth groove, the adjusting member is advanced by 4mm, so Figure 9 The length of the lock tongue extending out in the state is 12mm.

[0034] As shown in Figure 10 , 11 , 12, it further comprises a lock catch piece cooperating with the lock body and the lock tongue. The lock catch piece is provided with a cavity capable of accommodating the lock tongue, and is provided with a step structure near the side of the anti-theft hook of the lock tongue to cooperate with the anti-theft hook. As shown in Figure 7 , by pulling back the pull handle, the guiding body can be moved backward, thereby making the lock tongue retreat. As shown in Figure 13 , the lock body is connected with the inner leaf of the movable door and window, and the lock catch piece is connected with the outer leaf of the movable door and window.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent substitutions or changes to the technical solutions and novel concepts of the present application within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
