When the user drives the unlocking lever 42 to rotate clockwise through the key, the linkage pin 44 is pressed to move leftward along the linkage slot 43, so that the bottom of the linkage rod 45 moves downward, and then the top of the linkage rod 45 moves upward.

[0031] In this embodiment, as Figure 3 shown, a first rotating shaft 12 is provided in the front shell 1. The middle part of the linkage rod 45 is rotatably connected to the front shell 1 through the first rotating shaft 12. A first return torsion spring 13 is sleeved on the first rotating shaft 12, and both ends of the first return torsion spring 13 are abutted against the side of the front shell 1 and the side of the linkage rod 45 respectively.

[0032] Specifically, the first rotating shaft 12 is provided at the rear side of the front shell 1. When opening the door, the unlocking lever 42 drives the linkage rod 45 to rotate clockwise along the first rotating shaft 12. When resetting, an upward force is provided by the first return torsion spring 13 to drive the linkage rod 45 to rotate counterclockwise, so that the bottom of the linkage rod 45 moves upward to reset.

[0033] In this embodiment, as Figure 3 shown, both ends of the relay rod 51 are a force-receiving end and a control end respectively. The bottom of the force-receiving end bends and extends toward the direction close to the front shell 1 to form a force-receiving portion 53, and contacts the top of the linkage rod 45 through the force-receiving portion 53. A through slot 59 is provided at the position of the middle shell 2 corresponding to the control end. The control end bends and extends away from the front shell 1 to form a control block 54, and the control block 54 passes through the through slot 59 and contacts one end of the abutting block 52.

[0034] Specifically, the left and right ends of the relay rod 51 are a force-receiving end and a control end respectively. The left end extends forward to form a force-receiving portion 53, and the right end extends backward to form a control block 54. The bottom side of the force-receiving portion 53 contacts the top of the linkage rod 45, and the control block 54 presses on one end of the abutting block 52 to press down the abutting block 52 so that the abutting block 52 does not contact the limiting port 64 of the lock tongue member 6.

[0035] In this embodiment, as Figure 3 shown, a second rotating shaft 22 is provided on the side of the middle shell 2 close to the front shell 1. The middle part of the relay rod 51 is rotatably connected to the middle shell 2 through the second rotating shaft 22.

[0036] Specifically, the second rotating shaft 22 is arranged on the front side of the middle housing 2. A second return torsion spring 23 is sleeved on the second rotating shaft 22. Two ends of the second return torsion spring 23 are respectively abutted against the side of the middle housing 2 and the side of the relay rod 51.

[0037] In this embodiment, as Figure 3 shown, on the side of the middle housing 2 away from the front housing 1, a third rotating shaft 24 is arranged. One end of the abutting block 52 is rotatably connected to the middle housing 2 through the third rotating shaft 24. The other end of the abutting block 52 contacts the control block 54 of the relay rod 51. The middle part of the abutting block 52 extends upward to form an abutting part 58. The abutting part 58 abuts against the limiting port 64 of the lock tongue member 6.

[0038] Specifically, the third rotating shaft 24 is arranged on the rear side of the middle housing 2 so that the abutting block 52 is installed on the rear side of the middle housing 2. The left end of the abutting block 52 is rotatably connected to the middle housing 2 through the third rotating shaft 24. The right end of the abutting block 52 extends rightward. The control block 54 of the relay rod 51 is placed on the extended part of the abutting block 52. When the top of the linkage rod 45 moves upward to drive the force-receiving end of the relay rod 51 to move upward, the control block 54 at the control end of the relay rod 51 moves downward to press down the abutting block 52, so that the abutting part 58 of the abutting block 52 does not abut against the limiting port 64 of the lock tongue member 6.

[0039] In this embodiment, as Figure 3 shown, the control end of the relay rod 51 extends upward to form a restricted part 55. A restricted groove 56 is formed in the restricted part 55. A resilient post 57 is arranged at a position of the middle housing 2 corresponding to the restricted groove 56. At least a part of the resilient post 57 is arranged in the restricted groove 56.

[0040] Specifically, the right end of the relay rod 51 bends upward to form a restricted part 55. The restricted groove 56 is formed on the left side of the restricted part 55. The side wall of the restricted groove 56 is clamped by the resilient post 57 to limit the up-and-down movement range of the control end of the relay rod 51. If the key is not turned in place, and the top of the linkage rod 45 does not move upward in place, then the downward movement distance of the control end of the relay rod 51 cannot reach the preset position. At this time, the upper side of the resilient post 57 clamps the side wall of the restricted groove 56. At this time, the abutting part 58 of the abutting block 52 does not disengage from the limiting port 64 of the lock tongue member 6, and the locking hook member 32 cannot be buckled with the actuator block 65, and the door cannot be closed.

[0041] In this embodiment, as Figure 4As shown, the locking tongue member 6 includes a locking tongue seat 61, a fourth rotating shaft 62, and a third return torsion spring 63. The fourth rotating shaft 62 is disposed on a side of the middle shell 2 away from the front shell 1. The locking tongue seat 61 is disposed on the fourth rotating shaft 62. The third return torsion spring 63 is sleeved on the fourth rotating shaft 62, and its two ends are respectively abutted against a side of the middle shell 2 and a side of the locking tongue seat 61.

[0042] Specifically, the initial state of the locking tongue member 6 is a locked state, that is, the locking hook member 32 passes through the locking opening 31 and is buckled with the actuating block 65. By turning the key, the abutting portion 58 of the abutting block 52 is driven to move downward and not abut against the limiting opening 64 of the locking tongue member 6. Then, the third return torsion spring 63 drives the locking tongue seat 61 to rotate, and the locking hook member 32 can be disengaged from the locking opening 31.

[0043] In this embodiment, as Figure 4 shown, a limiting opening 64 is provided at a position of the lower part of the locking tongue seat 61 corresponding to the abutting portion 58 of the abutting block 52. An actuating block 65 is provided on a side of the locking tongue seat 61 close to the locking opening 31, and an actuating groove 66 is provided on an upper part of the actuating block 65.

[0044] Specifically, the right side of the locking tongue seat 61 is close to the locking opening 31, and the actuating block 65 is provided on the right side of the locking tongue seat 61. When using the key to open the door, the user inserts the key into the keyhole of the unlocking portion 41 to drive the unlocking rod 42 to rotate. The unlocking rod 42 drives the bottom of the linkage rod 45 to move downward, so that the top of the linkage rod 45 moves upward, and drives the stressed end of the relay rod 51 to move upward, so that the control block 54 at the control end of the relay rod 51 moves downward to press down the abutting block 52, so that the abutting portion 58 of the abutting block 52 does not abut against the limiting opening 64 of the locking tongue member 6. Then, the third return torsion spring 63 drives the locking tongue seat 61 to rotate, so that the actuating block 65 moves downward, so that the actuating groove 66 releases the locking hook member 32, and the locking hook member 32 is withdrawn from the locking opening 31, and the door is opened.

[0045] In this embodiment, as Figure 1 、 2 shown, an identification portion 11 is provided on an upper part of the front shell 1, a driving portion 21 connected to the identification portion 11 is provided on an upper part of the middle shell 2, and a working end of the driving portion 21 is connected to the locking tongue seat 61.

[0046] Specifically, the recognition part 11 is a control panel, which includes one or more electronic devices for authentication. The driving part 21 includes a motor and a connecting rod connected to the motor. The connecting rod is connected to the lock tongue seat 61. By swiping a card or / and entering a password on the recognition part 11, the driving part 21 drives the lock tongue seat 61 to rotate, causing the execution block 65 to move downward, so that the execution slot 66 releases the lock hook member 32, and the lock hook member 32 is withdrawn from the lock opening 31, opening the door.

[0047] It should be noted that the above technical features continue to be combined with each other to form various embodiments not listed above, which are all regarded as within the scope described in the specification of the present utility model; and for those of ordinary skill in the art, they can be improved or transformed according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
