[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Figure 1 A schematic diagram of the linkage lock structure according to an embodiment of the present invention is shown. Figure 2 A schematic diagram of the structure of the secondary lock component 2 in an embodiment of this utility model is shown. Figure 3 The diagram shows the structure of the main lock component 3 in an embodiment of the present invention. The linkage lock includes a mounting plate 1, a main lock component 3 and a secondary lock component 2 disposed on the mounting plate 1, and a first connecting rod 4 for connecting the main lock component 3 and the secondary lock component 2. The main lock component 3 and the secondary lock component 2 are linked and controlled based on the first connecting rod 4 to meet the fast linkage unlocking and locking operations between the main lock component 3 and the secondary lock component 2.

[0024] One end of the auxiliary locking component 2 is provided with a first hook 23, and any end of the main locking component 3 is provided with a second hook 34. One end of the first connecting rod 4 is engaged with the first hook 23, and the other end of the first connecting rod 4 is engaged with the second hook 34. The auxiliary locking component 2 and the main locking component 3 are linked together based on the first connecting rod 4. Through the cooperation of the first hook 23, the second hook 34 and the first connecting rod 4, the vertical movement of the first connecting rod 4 can realize the linkage movement between the main locking component 3 and the auxiliary locking component 2, reduce the risk of motion interference between the first connecting rod 4 and the main locking component 3 and the auxiliary locking component 2, and improve the reliability and stability of the linkage control between the main locking component 3 and the auxiliary locking component 2.

[0025] Specifically, the secondary lock component 2 is provided with a first locking tongue mechanism 21 and a linkage rod 22. The first locking tongue mechanism 21 is connected to the first hook 23 based on the linkage rod 22. The main lock component 3 drives the first hook 23 to rotate based on the first connecting rod 4, thereby driving the linkage rod 22 to rotate, realizing the extension and retraction movement of the first locking tongue mechanism 21 in the secondary lock component 2, thereby realizing the linkage control between the main lock component 3 and the secondary lock component 2.

[0026] Specifically, the main lock component 3 includes a keyhole 35, with a movement track for the key to rotate at the keyhole 35. One end of the second hook 34 is located on the movement track. The user rotates the key in the keyhole 35, causing the second hook 34 to rotate. This causes the first connecting rod 4 to move vertically, thereby causing the first hook 23 of the auxiliary lock component 2 to rotate, achieving linkage control.

[0027] Furthermore, the main lock component 3 also includes a second locking tongue mechanism 31 and a square tongue mechanism 32. A push plate 33 is provided between the square tongue mechanism 32 and the second locking tongue mechanism 31. One end of the push plate 33 extends on the motion track, and the locking between the second locking tongue mechanism 31 and the square tongue mechanism 32 is achieved based on the push plate 33.

[0028] Furthermore, the square tongue mechanism extends onto the motion track, and the square tongue mechanism, the push plate 33, and the second hook 34 are staggered and distributed on the motion track. When the user turns the key, the square tongue mechanism, the push plate 33, and the second hook 34 can be triggered synchronously according to the outline of the key to achieve a linkage unlocking operation.

[0029] Furthermore, the first locking tongue mechanism 21 of the secondary lock component 2 also includes a locking pin; the locking pin is provided with a mating groove, the linkage rod 22 is rotatably connected in the mating groove, and a spring is provided between the linkage rod 22 and the locking pin. Based on the spring, the linkage rod 22 can provide elastic pressure to the linkage rod 22, so that the linkage rod 22 can fit tightly in the groove of the door frame, thereby improving the reliability of closing and locking the door.

[0030] This utility model provides a linkage lock. Through the cooperation of a hook and a connecting rod, the vertical movement of the connecting rod can satisfy the linkage control between the main lock component 3 and the auxiliary lock component 2. The rotation of the bolt of the main lock component 3 can drive the bolt of the auxiliary lock component 2 to rotate through the connecting rod, thereby realizing the linkage control between the main lock component 3 and the auxiliary lock component 2. Furthermore, by setting a motor drive, the convenience of the linkage unlocking of the lock is improved.

[0031] Example 2:

[0032] Figure 4 The diagram shows a schematic of the linkage lock structure according to Embodiment 2 of the present invention. In this embodiment, the linkage lock further includes a motor drive component 5. The motor drive component 5 is connected to the main lock component 3 based on the second link 6. The motor drive component 5 relies on the motor box, through which a hook extends and engages with the waist-shaped hole of the second link 6, to realize the up and down sliding of the second link 6, thereby realizing the unlocking or locking of the main and auxiliary locks.

[0033] Furthermore, the motor box contains a wireless transmission module that receives electronic control signals from the electronic combination lock, or it can be connected to the electronic combination lock's wiring.

[0034] This utility model provides a linkage lock. Through the cooperation of a hook and a connecting rod, and by setting a motor drive, the vertical movement of the connecting rod can meet the linkage control between the main lock component 3 and the auxiliary lock component 2. The rotation of the bolt of the main lock component 3 can drive the bolt of the auxiliary lock component 2 to rotate through the connecting rod, thereby realizing the linkage control between the main lock component 3 and the auxiliary lock component 2 and improving the convenience of unlocking.
