It also includes a fixing assembly 2 and an adjustment assembly 3, and the adjustment assembly 3 is arranged on the back side of the fixing assembly 2, wherein: the fixing assembly 2 includes a fixing plate 21 and a first driving assembly 20, and a plug-in slot 27 is formed on the side wall of the fixing plate 21 close to the locking assembly 1, and the lock tongue 12 is plugged into the plug-in slot 27, and a fixing block 22 is slidably arranged in the plug-in slot 27, and a groove 13 is provided on the lock tongue 12, and the groove 13 of the lock tongue 12 is plugged and matched with the fixing block 22; the first driving assembly 20 is electrically connected to the sensor block 14, and the driving end of the first driving assembly 20 is meshed and connected with the fixing block 22; the adjustment assembly 3 includes a support The shaft 31, the knob 35, the limit block 33, the positioning block 32 and the push block 39, the front end of the support shaft 31 is rotatably connected to the back wall of the fixed plate 21, and at the same time, the front end of the support shaft 31 is connected to the meshing end of the first drive component 20; the knob 35 is sleeved on the outer peripheral wall of the support shaft 31, and at the same time, it is slidably arranged along the axial direction of the support shaft 31; the limit block 33 is slidably arranged in the support shaft 31, and the protruding end of the limit block 33 and the knob 35 can be disengaged from the card connection; the positioning block 32 is fixed to the back wall of the fixed plate 21, and the positioning block 32 and the inner wall of the knob 35 can be disengaged from the card connection; the push block 39 is slidably arranged in the fixed plate 21.
[0023] The anti-theft mechanism 100 for cathode lock according to the embodiment of the utility model is used in specific applications:
[0024] When the operator is outside the door and needs to open the door from the outside, the operator can directly operate the door lock 11, and the sensing block 14 of the door lock 11 sends a signal to the first driving component 20. After receiving the signal, the first driving component 20 engages with the fixing block 22 to drive the fixing block 22 to move outward and disengage from the groove 13 of the lock tongue 12. After that, the door lock 11 can control the lock tongue 12 to move outward to disengage from the fixing plate 21. At this time, the locking component 1 and the fixing component 2 are no longer fixed;
[0025] When the operator is inside the door and needs to open it from the inside, the operator can rotate the knob 35 to drive the support shaft 31 to rotate. After the support shaft 31 rotates, the engagement end of the first drive assembly 20 can also release the restriction of the fixing block 22 on the groove 13. Then, the lock tongue 12 can be retracted by rotating the handle 15;
[0026] When the operator is inside the door and does not need to open the door for a long time, the operator can push the knob 35 forward to move it forward until the positioning block 32 is completely engaged with the inner wall of the knob 35. At this time, the limit block 33 moves upward and blocks the knob 35, so that the knob 35 cannot move backward or rotate. At the same time, the meshing end of the first drive assembly 20 will also be synchronously fixed, and the device will be in an anti-theft state and cannot be opened. When unlocking is required, the limit block 33 is pushed downward so that it moves downward and no longer blocks the knob 35. The push block 39 drives the knob 35 to move backward and reset. At this time, the overall device of the cathode lock anti-theft mechanism 100 returns to normal. When the overall device is in the power-off state, the fixed block 22 is always stuck inside the groove 13, and the overall device will be self-locking. The device can only be unlocked by turning the knob 35 from the inside or restoring the power supply.
[0027] Through the above arrangement, the cathode lock anti-theft mechanism 100 of the utility model embodiment has the following advantages: 1) by using the fixing block to control the lock tongue 12, the lock tongue 12 can be fixed, and at this time the lock tongue 12 can neither rotate nor escape from the interior of the fixing component 2 by lateral movement, and the fixing effect of the overall device is better; 2) by the positioning block 32 clamping the knob 35, the fixing block 22 will be fixed and cannot move, and the lock tongue 12 will also be fixed and cannot move. Only after the knob 35 is released in the room, the fixing block 22 can resume movement, thereby effectively improving the anti-theft effect of the overall device.

[0029] Please continue to refer to Figure 3 In some embodiments, both the top wall and the bottom wall of the locking tongue 12 may be provided with a groove 13 .
[0030] Through this setting, in the present application, the correspondingly formed slideway 271 enables the fixing blocks 22 to be set at the top and bottom, and the two fixing blocks 22 are simultaneously engaged with the groove 13 to make the connection and fixation more stable and reliable. In the present application, the set fixing spring 23 can provide elastic force so that the fixing block 22 can be quickly engaged into the groove 13. In the present application, the side of the fixing block 22 close to the lock tongue 12 is configured with an inclined surface so that the horizontal force direction of the lock tongue 12 can be converted into a vertical force to provide a vertical thrust to the fixing block 22.

After the knob 35 moves beyond the limit block 33, the limit block 33 is reset so that the knob 35 is clamped on the other side of the limit block 33.
[0038] Please continue to refer to Figure 5 In some embodiments, the positioning blocks 32 are evenly distributed and fixed to the back wall of the fixing plate 21 along the circumference of the support shaft 31 .
[0039] Please continue to refer to Figure 5 In some embodiments, the push block 39 may be located at the upper and lower sides of the positioning block 32 .
[0040] Combined with the above, specifically:
[0041] In the present application, the fixing assembly 2 includes a fixing plate 21 for accommodating the whole fixing assembly 2, and the lock tongue 12 is inserted into the right end of the fixing plate 21. When the lock tongue 12 is inserted into the right end of the fixing plate 21, the locking assembly 1 will be fixed and cannot rotate, but at this time the locking assembly 1 can still drive the lock tongue 12 to disengage from the right end of the fixing plate 21 by lateral movement. The adjustment assembly 3 includes a support shaft 31 for supporting a knob 35, the front end of the support shaft 31 is rotatably connected to the rear end of the fixing plate 21, and the outer wall of the support shaft 31 is slidably connected with a knob 35 for driving the support shaft 31 to rotate. The rear end of the door lock 11 is equipped with a handle 15, which is an inherent component of the door lock 11. Rotating the handle 15 can drive the lock tongue 12 to move inward. The left end of the door lock 11 is equipped with a sensor block 14 for transmitting signals to the fixing assembly 2.
[0042] The top of the lock tongue 12 is provided with a groove 13 for accommodating a fixed block 22, and the inner wall of the fixed plate 21 is slidably connected with a fixed block 22 for fixing the lock tongue 12, and the lock tongue 12 and the fixed block 22 are adapted. The right end of the fixed block 22 is provided with an inclined surface, and the fixed block 22 will be forced to move upward when it is squeezed to the left. When the fixed block 22 is stuck in the inside of the groove 13, the lock tongue 12 will be fixed and cannot move. The bottom end of the fixed block 22 is fixedly connected with a fixed spring 23 for driving the fixed block 22 to move inward, and the bottom end of the fixed spring 23 is fixedly connected to the inner wall of the fixed plate 21, and the fixed spring 23 will keep pushing the fixed block 22 inward. The rear end of the fixed block 22 is fixedly connected with a rack 25 for driving the fixed block 22 to move. The rack 25 is slidably connected to the inner wall of the fixed plate 21. When the fixed block 22 moves up and down, it will drive the rack 25 to move synchronously. The inner wall of the fixed plate 21 is rotatably connected with a rotating wheel 26 for cooperating with the rack 25. The rotating wheel 26 and the rack 25 are meshed with each other. When the rack 25 moves up and down, it will drive the rotating wheel 26 to rotate. The inner wall of the fixed plate 21 is installed with an electric push rod 24 for driving the rack 25 to move up and down. The bottom end of the output shaft of the electric push rod 24 is fixedly connected to the top of the rack 25. The electric push rod 24 is controlled by the power supply. After the power is off, its output shaft can move freely. At the same time, the electric push rod 24 can also be controlled to move up and down by using the induction block 14 to transmit a signal to the electric push rod 24.
[0043] The rear end of the rotating wheel 26 is fixedly connected to the front end of the supporting shaft 31, and the rotating wheel 26 can be driven to rotate synchronously by rotating the supporting shaft 31. The rear end of the supporting shaft 31 is penetrated and slidably connected with a limit block 33 used to block the knob 35, and the bottom end of the limit block 33 is fixedly connected with a limit spring 34 used to drive the limit block 33 to move outward. The bottom end of the limit spring 34 is fixedly connected to the inner wall of the supporting shaft 31, and the limit spring 34 will always push the limit block 33 outward so that it can block the knob 35. The inner wall of the knob 35 is provided with a receiving groove 36 for accommodating the limit block 33, and the limit block 33 and the receiving groove 36 are adapted. The rear end of the limit block 33 is provided with an inclined surface, and when the knob 35 tries to move backward, the limit block 33 will be stuck in the inside of the receiving groove 36 so that it cannot move outward. When the knob 35 tries to move forward, the receiving groove 36 will squeeze the inclined surface of the limit block 33 to force the limit block 33 to move downward.
[0044] The rear end of the fixed plate 21 is fixedly connected with a positioning block 32 for fixing the knob 35. The rear end of the knob 35 is provided with a positioning groove 37 for accommodating the positioning block 32. The positioning groove 37 and the positioning block 32 are adapted. When the positioning block 32 is inserted into the positioning groove 37, the knob 35 will be fixed and cannot rotate. The rear end of the fixed plate 21 is slidably connected with a push block 39 for driving the knob 35 to move backward and reset near the top of the positioning block 32. The front end of the push block 39 is fixedly connected with a push spring 38 for pushing the push block 39. The front end of the push spring 38 is fixedly connected to the rear end of the fixed plate 21. When the knob 35 moves forward, the push spring 38 is forced to contract by squeezing the push block 39. When the knob 35 is no longer restricted, the push spring 38 will recover and drive the knob 35 to move backward and reset by pushing the push block 39.
[0045] In summary, the working principle of the cathode lock anti-theft mechanism 100 of the utility model embodiment is as follows:
[0046] When the device needs to be opened from the outside, the door lock 11 can be directly operated. The door lock 11 will send a signal to the electric push rod 24 through the sensor block 14. The electric push rod 24 will push the rack 25 downward after receiving the signal. The downward movement of the rack 25 will drive the rotating wheel 26 to rotate. The rotation of the rotating wheel 26 will drive the two sets of racks 25 to move in the opposite direction. When the rack 25 drives the fixing block 22 to move outward and disengage from the inside of the groove 13, the door lock 11 can control the groove 13 to move right and disengage from the right end of the fixing plate 21. At this time, the locking component 1 and the fixing component 2 will no longer be fixed.
[0047] When the operator is inside the door, the support shaft 31 can be rotated by directly rotating the knob 35 , and the rotation of the support shaft 31 can also drive the rotating wheel 26 to rotate and contact the restriction of the groove 13 , and then the groove 13 can be retracted by rotating the handle 15 .
[0048] When the operator is inside the door and does not need to open the door for a long time, the knob 35 can be pushed forward to move it forward until the positioning block 32 is completely stuck in the positioning groove 37. At this time, the limit spring 34 will push the limit block 33 upward to move it upward to block the knob 35. At this time, the knob 35 will not be able to move backward or rotate. At the same time, the rotating wheel 26 will also be fixed synchronously. At this time, the device will be in an anti-theft state and cannot be opened. When unlocking is required, it is only necessary to push the limit block 33 downward to move it downward and no longer block the knob 35. The push spring 38 can push the push block 39 forward to drive the knob 35 to move backward and reset. At this time, the device will return to normal state. When the device is in the power-off state, the fixing spring 23 will push the fixing block 22 to keep it stuck in the groove 13. In this way, the device will be self-locking. The device can only be unlocked by turning the knob 35 from the inside or restoring the power supply.
