[0028] Example 1

[0029] A lock body linkage mechanism, such as Figure 1-3 As shown, it includes a main lock component, a secondary lock component, an outer opening lever arm 5, a linkage arm 11 and a locking conversion arm 8. The secondary lock component is arranged on one side of the linkage arm 11, and the main lock component includes an opening hook 4, an outer opening lever arm 5 and an opening connecting arm 6; the opening connecting arm 6 and the opening hook 4 are arranged on one side of the outer opening lever arm 5 in sequence, and a claw and a claw connecting shaft are provided on one side of the opening hook 4, and the locking conversion arm 8 is arranged on one side of the opening hook 4;

[0030] The outer opening lever arm 5 is connected to the inner opening handle and / or the outer opening handle, and the locking conversion arm 8 drives the opening hook 4 to rotate forward, so that the opening hook 4 is engaged with the claw connecting shaft of the claw, and the main lock component is in an unlockable state (that is, it can be unlocked at any time by driving the claw connecting shaft to rotate by the opening hook 4). At the same time, the rotation of the opening hook 4 drives the third linkage arm connecting shaft 10 of the linkage arm 11 to rotate until it is engaged with the secondary lock component, and the secondary lock component is in an unlockable state; the rotation of the outer opening lever arm 5 drives the opening connecting arm 6 to rotate, and the opening connecting arm 6 drives the opening hook 4 to continue to rotate, and the claw connecting shaft of the claw is driven to rotate by the opening hook 4, so that the main lock component is unlocked, and the opening hook 4 drives the linkage arm 11 to rotate, and the linkage arm 11 drives the secondary lock component to be unlocked;

[0031] The lock conversion arm 8 drives the opening hook 4 to rotate in the opposite direction, so that the opening hook 4 is disengaged from the claw connecting shaft of the claw, and the main lock component is in a locked state; the opening hook 4 drives the linkage arm 11 to rotate, and the linkage arm 11 is disengaged from the secondary lock component, and the secondary lock component is in a locked state. The lock body is modularly designed to realize that one opening handle can open two locks at the same time, and when locking, pressing the lock switch can lock the two locks at the same time. It has the advantages of simple structure, light weight, reliable opening, low cost, etc., and keeps up with the trend of intelligence of the times.

[0032] Furthermore, the lock body linkage mechanism also includes a lock housing 3, and the main lock component, the auxiliary lock component and the linkage arm 11 are all arranged in the lock housing 3.

[0033] Furthermore, a first linkage arm connecting shaft 1 is provided on the linkage arm 11, one end of which is suspended and arranged on one side of the opening hook 4; when the opening hook 4 rotates, the linkage arm 11 is driven to rotate by pushing the first linkage arm connecting shaft 1.

[0034] A locking positioning hole is provided on the linkage arm 11 , and the first linkage arm connecting shaft 1 is connected to the linkage arm 11 through the locking positioning hole 11 - 2 .

[0035] Furthermore, a second linkage arm connecting shaft 2 is connected to the first end of the linkage arm 11 , and the linkage arm 11 is riveted to the outer opening arm 5 via the second linkage arm connecting shaft 2 .

[0036] Furthermore, a third linkage arm connecting shaft 10 is connected to the second end of the linkage arm 11, and a lower end of the third linkage arm connecting shaft 10 is suspended and arranged at one side of the secondary lock rotating arm 9 of the secondary lock component.

[0037] Example 2

[0038] The secondary lock component is further limited on the basis of Example 1, and the performance of Example 2 after the limitation is better.

[0039] The secondary lock component includes a secondary lock rotating arm 9, which is arranged on one side of the third linkage arm connecting shaft 10; when the secondary lock component is in an unlocked state, the third linkage arm connecting shaft 10 of the linkage arm 11 is in the groove of the secondary lock rotating arm 9, forming an engagement between the linkage arm 11 and the secondary lock rotating arm 9; when the secondary lock component is in a locked state, the third linkage arm connecting shaft 10 of the linkage arm 11 is out of the groove of the secondary lock rotating arm 9, forming a disengagement between the linkage arm 11 and the secondary lock rotating arm 9.

[0040] When the lock body is unlocked, the lock conversion arm 8 drives the linkage arm 11 to rotate forward through the opening hook 4, so that the linkage arm 11 is engaged with the secondary lock rotating arm 9, and the secondary lock component is in an unlockable state. The external opening lever arm 5 can drive the linkage arm 11 to continue rotating through the opening hook 4 at any time, and then drive the secondary lock rotating arm 9 to rotate through the linkage arm 11, so that the secondary lock component is opened;

[0041] When the lock body is locked, the locking rotating arm 8 drives the opening hook 4 to rotate, and the opening hook 4 drives the linkage arm 11 to rotate through the first linkage arm connecting shaft 1, so that the third linkage arm connecting shaft 10 of the linkage arm 11 is disengaged from the secondary lock rotating arm 9 of the secondary lock component, thereby locking the secondary lock body.

[0042] Furthermore, the main lock component also includes an auxiliary base plate 7, and the secondary lock rotating arm 9 is arranged on the auxiliary base plate 7 through a rotating shaft.

[0043] A positioning hole 7 - 1 is provided on the auxiliary bottom plate 7 , and a raised shaft is connected to the secondary lock rotating arm 9 , and the raised shaft is provided in the positioning hole 7 - 1 .

[0044] Furthermore, an open positioning hole 11-1 and a secondary locking positioning hole 11-3 are respectively provided at both ends of the linkage arm 11, the second linkage arm connecting shaft 2 is connected to the linkage arm 11 through the open positioning hole 11-1, and the third linkage arm connecting shaft 10 is connected to the linkage arm 11 through the secondary locking positioning hole 11-3.

[0045] Three positioning holes are set on the linkage arm 11 for connecting with the opening part, the locking part and the auxiliary lock part respectively, so as to realize the linkage function of the main lock and the auxiliary lock; the three positioning holes on the linkage arm 11 are respectively the opening positioning hole 11-1, the locking positioning hole 11-2 and the auxiliary locking positioning hole 11-3.

[0046] Furthermore, a distance of at least 6 mm is maintained between the top of the opening hook 4 and the bottom of the first linkage arm connecting shaft 1 to ensure the strength of the first linkage arm connecting shaft 1 and prevent the locking function from failing in harsh environments.

[0047] The working process of the present invention is as follows: Unlocking: When the inner or outer opening handle is pulled, the inner or outer opening handle will pull the outer opening lever arm 5 to drive the opening connecting arm 6, the opening hook 4, and the linkage arm 11 to rotate, thereby unlocking the main lock body. At the same time, the linkage arm 11 rotates to drive the third linkage arm connecting shaft 10 to move, so that the third linkage arm connecting shaft 10 is disengaged from the secondary lock rotating arm 9, thereby unlocking the secondary lock body.

[0048] Locking: When the central control is locked, the locking rotating arm 8 rotates, driving the opening hook 4 to disengage from the claw connecting shaft, and the opening hook 4 drives the linkage arm 11 to move through the first linkage arm connecting shaft 1, so that the third linkage arm connecting shaft 10 of the linkage arm 11 disengages from the secondary lock rotating arm 9, and the main lock body and the secondary lock body are locked. At this time, whether the inner opening handle or the outer opening handle is pulled, unlocking cannot be achieved.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
