[0002] PLC (Programmable Logic Controller) modules are widely used in industrial automation and other fields. Their installation and removal usually rely on manual operation. In the traditional way, for PLC modules installed in special locations (such as high places or confined spaces), direct manual operation is inconvenient, time-consuming and labor-intensive, and is prone to damage or insecure installation due to improper operation, which will affect the operation of the equipment. Therefore, a convenient disassembly and installation rack for PLC modules is proposed. Utility Model Content

[0003] In view of this, the present invention provides a convenient disassembly and installation bracket for PLC modules, which aims to solve one of the technical problems of inconvenient and inefficient installation and disassembly of traditional PLC modules in the prior art.

[0004] The technical solution of this utility model embodiment is implemented as follows: a convenient disassembly and installation bracket for a PLC module, including a main component and a PLC module body. The main component includes a base, a first bolt pin, a first folding connecting rod, and a connecting block. The two sides of the base are symmetrically connected to the bottom of the first folding connecting rod through the first bolt pin. The top of the first folding connecting rod is connected to the inside of the connecting block through the first bolt pin. The opposite surface of the connecting block is threaded with a fixing claw by a fixing bolt. A limiting component is connected to the top outer side of the first folding link. A rotating component is installed inside the main body component and the limiting component. The PLC module body is locked inside the two sets of fixed claws. A handle is fixedly connected to one side of the base.

[0005] A further preferred embodiment: the limiting assembly includes a platform, a second folding link, a second bolt pin, and a nut seat. The front and rear sides of the platform are hinged to the bottom of the second folding link via the second bolt pin. The top of the second folding link is hinged to the outer side of the top of the first folding link. A nut seat is provided inside the platform.

[0006] A further preferred embodiment: the rotating assembly includes a drive disk, a rocker arm, limiting holes, and a lead screw. The drive disk is located below the bottom of the base. The interior of the drive disk is threadedly connected to the nut seat through the lead screw passing through the interior of the base. A rocker arm is threadedly connected to one side of the drive disk. Four sets of limiting holes are provided inside the drive disk.

[0007] A further preferred embodiment: a connecting bracket is fixedly connected to the end face of the base away from the handle.

[0022] The base is made of ABS engineering plastic through one-piece injection molding, which is lightweight and has high mechanical strength.

[0023] The main component 10 consists of a base 101, a first bolt pin 102, a first folding connecting rod 103, and a connecting block 104. The base 101 is hinged to the bottom of the first folding connecting rod 103 on both sides via the first bolt pin 102. The top of the first folding connecting rod 103 is hinged to the inside of the connecting block 104 via the first bolt pin 102. The opposite surfaces of the connecting block 104 are connected to fixing claws 106 via fixing bolts 105. The bottom of the opposite surfaces of the fixing claws 106 are provided with elastic anti-slip pads 107 (made of rubber, providing both anti-slip and cushioning performance). A limiting component 20 is connected to the outer top of the first folding connecting rod 103. A rotating component 30 is installed inside the main component 10 and the limiting component 20. The PLC module body 100 is locked inside the two sets of fixing claws 106.

[0026] Working principle: In use, the operator moves the handle 40 to the vicinity of the PLC module body 100, and cranks the crank 302 to rotate the drive plate 301. The drive plate 301 rotates the lead screw 304, which engages with the nut seat 204 to move the platform 201 up and down, thereby unfolding / retracting the second folding link 202 and the first folding link 103. When unfolded, the fixing claws 106 open to both sides, placing the PLC module body 100 between the two sets of fixing claws 106. When cranking the handle 302 in the opposite direction, the folding link retracts, the fixing claws 106 clamp the PLC module, and the elastic anti-slip pad 107 provides anti-slip protection. Disassembly is performed by reversing the operation. After the drive plate 301 is rotated to the appropriate position, a limit pin can be inserted to fix its position.
