LRM module needs to be quickly installed or disassembled from the equipment cabinet in the work site or the outside field. At present, the LRM module and the LRM rack are installed or disassembled in a time-consuming and laborious manner. For example, the invention application CN116000607A discloses a module integrated locking and pulling aid device, which comprises a forward wedge-shaped locking mechanism, a reverse wedge-shaped locking mechanism, a pulling aid mechanism and a rotating screw rod. The forward wedge-shaped locking mechanism and the reverse wedge-shaped locking mechanism are coaxially installed on the rotating screw rod. The wedge-shaped blocks on the forward wedge-shaped locking mechanism and the reverse wedge-shaped locking mechanism are driven to move towards each other by the rotating screw rod. The pulling aid mechanism is installed at the end of the rotating screw rod and is used for manually controlling the rotating screw rod. However, the locking and pulling aid device is not connected with the LRM module or the LRM rack after disassembly, which is easy to cause the locking and pulling aid device to be lost. In addition, the patent only relies on the abutment of wedge-shaped block one and wedge-shaped block two with the side walls of the LRM rack and the LRM module for locking, which is easy to loosen or even fall out during use.

By passing through briquetting 101 and being connected in the threaded hole that sets up on LRM rack 200 of threaded rod spare, can make the first clamping surface and second clamping surface of briquetting 101 adhere to clamp LRM rack 200 and LRM module 300 corresponding clamping surface, and, threaded rod spare is connected with LRM rack 200 by screw thread, and the locking effect is better, and the vibration is not easy to come out, and when LRM module 300 is detached from LRM rack 200, the connecting piece 102 can be unscrewed, can not completely take out connecting piece 102 from the threaded hole, sliding briquetting 101 along the direction of stop piece 111, do not need to take down module locker 100 from LRM rack 200, can detach LRM module 300 from LRM rack 200, when needing to frequently dismount or under complex environment use, can effectively avoid module locker 100 loss. Preferably, connecting piece 102 is bolt.

[0033] When using, the first clamping surface and the second clamping surface of the briquetting 101 correspond to the clamping surface of the LRM rack 200 and the LRM module 300, and the limiting piece 111 is tightened. As the threaded rod passes through the briquetting 101 and is screwed into the bolt hole of the LRM rack 200, the limiting piece 111 presses the connecting block of the briquetting 101, so that the first clamping surface and the second clamping surface of the briquetting 101 clamp the corresponding clamping surface of the LRM rack 200 and the LRM module 300, and the LRM rack 200 and the LRM module 300 are locked.

[0034] In another embodiment of the present embodiment, when the LRM rack 200 and the LRM module 300 are locked by the module locker 100, the end of the LRM module 300 away from the module locker 100 can be used to screw the LRM rack 200 and the LRM module 300 together by hand, thereby limiting the LRM rack 200 and the LRM module 300.

[0035] In another embodiment of the present embodiment, the module locker 100 further comprises a handle 106 connected to the end of the limiting member 111 away from the threaded rod member. When the handle 106 is in the first state, the handle 106 extends along the axis direction of the threaded rod member, and rotating the handle 106 can drive the connecting member 102 to rotate around the axis of the threaded rod member.

When the connecting member 102 is screwed into the bolt hole on the LRM rack 200, the limiting member 111 can compress the first spring 104 on the pressing block 101. The first spring 104 is compressed and generates a pre-tightening force, which can increase the pressure on the connecting block, making the LRM rack 200 and the LRM module 300 more firmly locked. Moreover, the first spring 104 can provide a buffer force between the limiting member 111 and the pressing block 101, which can reduce the rigid contact between the components and prolong the service life. When it is necessary to disassemble the LRM module 300 from the LRM rack 200, the elastic potential energy stored in the first spring 104 during compression is gradually released as the connecting member 102 is unscrewed, pushing the limiting member 111 to separate from the pressing block 101, making it more labor-saving to disassemble.

The first opening of the sleeve 103 is capable of pressing against the pressing block 101, so that the pressing block 101 is locked with the LRM rack 200 and the LRM module 300, the limiting member 111 can enter the sleeve 103 through the second opening of the sleeve 103 and rotate therein, and the first elastic member 104 is limited in the sleeve 103, effectively avoiding the deformation thereof due to the force of the limiting member 111.
