DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example 1

[0028] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides an interlocking lock structure, which includes: a locking rod 1, a guide plate 2, and an interlocking assembly having a locking position and an unlocking position, a linear guide rail slidably connected to the interlocking assembly is provided on the guide plate 2, one end of the locking rod 1 is rotatably penetrated through the guide plate 2, and is drivingly connected to the interlocking assembly, the locking rod 1 is driven to rotate and drives the interlocking assembly to slide along the extension direction of the linear guide rail to switch between the locking position and the unlocking position.

[0029] In a specific embodiment, the guide plate 2 is connected to an external drawer 10 to be locked or a cabinet body 9 of a tool cabinet, and is used to install a locking rod 1 and an interlocking assembly. Specifically, the locking rod 1 is rotatably connected to the guide plate 2. At the same time, one end of the locking rod 1 is drive-connected to the interlocking assembly, and the interlocking assembly can be driven to move to lock or unlock by rotating the locking rod 1. Specifically, a linear guide rail is provided on the guide plate 2. The interlocking assembly is connected to the linear guide rail and can reciprocate in a straight line along the extension direction of the linear guide rail. Through the limiting of the linear guide rail, it is ensured that the interlocking assembly always moves in a straight line direction during the process of switching the locking position and the unlocking position, thereby avoiding the situation of prying during the movement of the interlocking assembly.

[0030] It is understandable that the existing interlocking structure usually directly connects the lock rod 1 to the interlocking assembly, and the interlocking assembly is easily deformed or pried due to the force deviating from the moving direction during movement. When the interlocking assembly is deformed, it is easy to cause problems such as unsmooth opening and closing of the lock and easy to get stuck.

[0031] Optionally, in a specific implementation, the interlocking assembly includes an interlocking crosspiece 3 and an interlocking block 4 , the interlocking crosspiece 3 is slidably connected to the linear guide rail, and the interlocking block 4 is rotationally connected to the interlocking crosspiece 3 .

[0032] In a specific embodiment, the interlocking crossbar 3 and the interlocking block 4 are rotatably connected by means of a pin shaft or a bolt, etc. The interlocking block 4 can be set as a strip structure, and a plurality of lock holes 401 are provided on the interlocking block 4, and the lock holes 401 are used to connect external lock buckles. When the interlocking block 4 is driven to move, the external lock buckle is clamped in the lock hole 401, and the interlocking assembly is in a locked position. After the interlocking block 4 is driven to move, the external lock buckle can be disengaged from the lock hole 401, and the interlocking assembly is in an unlocked position, and the locking rod 1 drives the interlocking assembly to move to achieve locking and unlocking. Multiple interlocking blocks 4 can be rotatably connected to the interlocking crossbar 3, which can be used to lock multiple devices to be locked arranged horizontally or form multiple locking points to ensure the firmness after locking. Since the interlocking block 4 is rotatably connected to the interlocking crossbar 3, it has a certain degree of rotational freedom, and can be slightly rotated and fine-tuned during the movement to prevent jamming. It can be understood that the interlocking block 4 is easily subjected to external force during the movement process, causing movement jamming. For example, the interlocking block 4 cannot move in a straight line due to the blocking of the lock buckle, while the interlocking crossbar 3 must move in a straight line, which will cause jamming. In this embodiment, the interlocking block 4 is rotationally connected to the interlocking crossbar 3. The interlocking block 4 can be slightly rotated during the movement to avoid interference or jamming with external structures such as the lock buckle and the moving track 5, causing the switch lock to jam. At the same time, the rotational connection between the interlocking block 4 and the interlocking crossbar 3 forms a synergistic effect with the linear guide rail on the guide plate 2, which further improves the smoothness of the interlocking assembly during the switch lock process while ensuring that the interlocking assembly is not deformed by prying, thereby avoiding jamming.

[0033] In a specific embodiment, the linear guide rail includes a plurality of mounting posts 302 arranged in a straight line, and a first strip hole 301 for accommodating the mounting posts 302 is opened on the interlocking crossbar 3 along the arrangement direction of the mounting posts 302, and the interlocking crossbar 3 is slidably connected to the mounting posts 302 through the first strip hole 301.

[0034] Optionally, a mounting post 302 is provided on the guide plate 2, and the mounting posts 302 are arranged in a straight line. A first bar hole 301 is correspondingly provided on the interlocking crossbar 3, and the interlocking crossbar 3 is slidably connected to the mounting post 302 through the first bar hole 301. The guide plate 2 and the interlocking crossbar 3 are connected by the mounting post 302, so that the interlocking crossbar 3 can move along the direction of the first bar hole 301. When the mounting post 302 moves to one end of the bar hole, the interlocking assembly is in an unlocked position, and when it moves to the other end, the interlocking assembly is in a locked position. At the same time, a plurality of mounting posts 302 arranged in a straight line are provided, which can increase the connection strength and prevent the interlocking crossbar 3 from being detached. On the other hand, a plurality of mounting posts 302 arranged in a straight line form a linear guide rail, so that the interlocking crossbar 3 can only move in a straight line along the first bar hole 301, and will not rotate around a single mounting post 302.

[0035] Optionally, in some other implementations, a plurality of first strip holes 301 may be provided in parallel on the interlocking crossbar 3, and a mounting column 302 is provided in each first strip hole 301. By combining the plurality of mounting columns 302 with the plurality of first connecting holes 701, the movement and limiting effect of the interlocking crossbar 3 is improved, and the interlocking crossbar 3 is ensured to move in a straight line.

[0036] Optionally, in some other embodiments, the linear guide rail may also be a linear slide rail structure.

[0037] In a specific embodiment, a second strip hole 303 perpendicular to the linear guide rail is opened on the interlocking crossbar 3, and a linkage part 101 eccentric to the rotation axis of the locking rod 1 is provided at one end of the locking rod 1. The linkage part 101 is rotatably passed through the second strip hole 303 to drive the locking rod 1 to be connected with the interlocking assembly.

[0038] Optionally, the linkage part 101 can be a Z-shaped structure formed by bending the locking rod 1. The interlocking crosspiece 3 of the interlocking assembly shown is provided with a second strip hole 303, and the second strip hole 303 is perpendicular to the first strip hole 301. The linkage part 101 is penetrated in the second strip hole 303 on the interlocking crosspiece 3. Since the interlocking part is eccentrically arranged, when the locking rod 1 is driven to rotate, the eccentrically arranged interlocking part drives the interlocking crosspiece 3 to move circumferentially. Since the interlocking crosspiece 3 is provided with a transverse second strip hole 303, the interlocking part can slide in the second strip hole 303. Therefore, when the interlocking part moves, it will only drive the interlocking crosspiece 3 to move in the direction of the first strip hole 301 perpendicular to the second strip hole 303, and under the limit of the mounting column 302, the linear movement of the interlocking crosspiece 3 is realized.

[0039] Please refer to Figure 3 and Figure 4 As shown, optionally, in a specific embodiment, a lock head 6 and a connecting portion 7 are provided at one end of the lock rod 1 away from the linkage portion 101, one end of the connecting portion 7 is fixedly connected to the lock head 6, and the other end is connected to the lock rod 1, and the lock head 6 is driven to rotate the lock rod 1 through the connecting portion 7.

[0040] A lock head 6 is arranged at one end of the lock rod 1, and a key or an unlocking tool is required to drive the internal lock rod 1 to rotate, thereby improving the safety of the interlocking lock structure.

[0041] In a specific implementation, the connecting portion 7 is provided with a connecting hole 701 , and a square shaft 702 is provided at one end of the locking rod 1 close to the connecting portion 7 , and the square shaft 702 is slidably inserted into the connecting hole 701 .

[0042] The locking rod 1 is slidably connected to the connecting portion 7 through the square shaft 702. At the same time, the locking rod 1 will not rotate relative to the square shaft 702 under the cooperation of the connecting hole 701, so as to ensure that the locking rod 1 can be driven to rotate through the connecting portion 7. The connecting portion 7 can be provided with a U-shaped structure, and an installation gap is formed inside. The connecting portion 7 is slidably connected to the locking rod 1. On the one hand, it is convenient to install the locking rod 1 and adjust the installation position of the locking rod 1. When installing, it is only necessary to align the square ark with the connecting hole 701. On the other hand, the installation gap of the mounting part of the connecting portion 7 can be used to adjust the mounting rod to avoid the mounting rod from being stuck with other parts due to thermal expansion and contraction.

[0043] It should be noted that the square shaft 702 can be any polygonal structure, such as a triangle, a quadrilateral, a hexagon, etc., or a flat structure, so long as the connecting portion 7 drives the locking rod 1 to rotate.

[0044] In a specific embodiment, a locking socket 703 is provided on the square shaft 702, and the connecting hole 701 has a distal opening away from the locking rod 1. A locking pin can be passed through the locking socket 703, and the locking pin can abut against the peripheral edge of the distal opening.

[0045] It can be understood that the locking rod 1 is slidably connected to the connecting portion 7 shown, and the locking rod 1 may be separated from the connecting portion 7 during use. A locking socket 703 is provided at one end of the square shaft 702 of the locking rod 1. When the square shaft 702 with the locking socket 703 is inserted into the connecting hole 701, a locking pin can be inserted into the locking socket 703. When the locking rod 1 is moved toward the connecting portion 7, the locking pin abuts against the distal end of the connecting hole 701, thereby preventing the locking rod 1 from falling off.

[0046] Optionally, in a specific embodiment, a fixing hook 8 is provided on the connecting portion 7 for connecting to an external buckle.

[0047] The fixed hook is integrally formed with the connecting portion 7. When the lock head 6 drives the connecting portion 7 to rotate, the fixed hook rotates together, thereby engaging with the external buckle to lock or unlock. At the same time, the buckle can also limit the rotating portion, limit the rotation angle of the lock rod 1, and avoid 360-degree rotation of the lock rod 1, so that the interlocking assembly cannot be accurately stopped at the locked position or unlocked position.

[0048] Optionally, the interlocking structure further includes a moving track 5 , which is mounted on an external device to be locked, and the interlocking block 4 is slidably connected to the moving track 5 .

[0049] The moving track 5 has the same direction as the first strip hole 301 and is used to fix the interlocking block 4 . The interlocking block 4 slides linearly along the moving track 5 , thereby improving the stability of the interlocking block 4 during movement and locking.

[0050] Example 2

[0052] In a specific embodiment, the tool cabinet adopts the interlocking lock structure provided in the above embodiment, and the lock rod 1, the guide plate 2 and the interlocking assembly are all arranged inside the tool cabinet. A plurality of drawers 10 can be arranged in the cabinet body 9, and the drawers 10 are slidably connected to the cabinet body 9, and a lock hook 11 is arranged on each drawer 10. When the interlocking assembly is driven to move to the unlocking position, the lock hook 11 of the drawer 10 can extend into the lock hole 401 of the interlocking block 4 or detach from the lock hole 401, and the drawer 10 is in an unlocked state. When the interlocking assembly is driven to move to the locking position, the lock hook 11 abuts against the interlocking block 4, and the drawer 10 is in a locked state and cannot be opened smoothly. With the guide plate 2 and the linear guide rail of the above interlocking lock structure, the tool cabinet can be opened and closed smoothly, and it will not be pried or stuck during long-term use.
