According to the utility model, the PCB is mainly connected with the lamp box shell through the disassembling screw, so that the PCB can be fixed, but the screw can be rusted in the long-term placing process, once the screw is rusted, a person needs to screw the rusted screw when the PCB needs to be disassembled, the rusted screw is difficult to screw, and meanwhile, the situation of sliding teeth is easy to occur, so that more trouble than necessary is brought to the person, and meanwhile, the PCB is difficult to disassemble by the person.

[ utility model ]

The utility model aims to solve the problems in the prior art and provides a detachable lamp box device which can facilitate the disassembly of a PCB.

In order to achieve the above purpose, the utility model provides a detachable lamp box device, which comprises a lamp box, a PCB board arranged in the lamp box and a PLC module arranged on the PCB board,

The device also comprises a supporting block, a supporting rod and a pushing block;

The supporting block is fixedly connected to the inner wall of the lamp box;

The support rods are arranged in an L shape and are connected to the support blocks in a relatively elastic sliding manner, and the PCB is provided with connecting holes for the support rods to enter;

the pushing block is elastically connected to the supporting block in a sliding manner and can be attached to the PCB.

Preferably, the support rod is provided with an inclined surface, and the inclined surface can be attached to the connecting hole.

Preferably, a plurality of balls are rotatably connected to the inclined surface.

Preferably, a first spring is fixedly connected between the support rods.

Preferably, the support block is fixedly connected with a second spring, one end of which is fixedly connected with the push block.

Preferably, the pushing block is fixedly connected with a sponge, and one end of the sponge is attached to the PCB.

The utility model has the beneficial effects that: compared with the prior art, the utility model has the advantages that the supporting rods are positioned between the connecting holes by moving the supporting rods, at the moment, the pushing block can push the PCB to move to the outside, the PCB is not required to be disassembled easily due to rust of the sliding teeth of the bolts, and the PCB is fixed in the mode, so that the PCB is convenient to fix by the personnel, the installation efficiency of the personnel can be greatly improved without screwing the bolts by the personnel, and the PCB is convenient to install by the personnel.

The features and advantages of the present utility model will be described in detail by way of example with reference to the accompanying drawings.

[ Description of the drawings ]

FIG. 1 is a schematic diagram of the structure of the present utility model;

Fig. 2 is a schematic view of the location of the support blocks of the present utility model.

In the figure: 1. a light box; 2. a PCB board; 3. a PLC module; 4. a support block; 5. a support rod; 6. a pushing block; 7. a connection hole; 8. an inclined surface; 9. a ball; 10. a first spring; 11. a second spring; 12. and (3) a sponge.

[ Detailed description ] of the invention

As shown in fig. 1 to 2, the detachable lamp box 1 device comprises a lamp box 1, a PCB board 2 arranged in the lamp box 1 and a PLC module 3 arranged on the PCB board 2,

The device also comprises a supporting block 4, a supporting rod 5 and a pushing block 6;

In actual operation, because supporting shoe 4 fixed connection is on the inner wall of lamp house 1, consequently personnel can press PCB board 2 and get into in the bracing piece 5 of relative elasticity sliding connection on supporting shoe 4 through seting up connecting hole 7 on PCB board 2, utilize bracing piece 5 that the L type set up to fix PCB board 2, and then reach the installation of PCB board 2, and then only need remove bracing piece 5 when dismantling, utilize bracing piece 5 relative movement, make elasticity sliding connection push away the piece 6 on supporting shoe 4 promote PCB board 2 and remove to the external world, and then realize the dismantlement of PCB board 2, and be worth an organic whole, connecting hole 7's size sets up according to bracing piece 5, and can set up a plurality of balls 9 on the bracing piece 5, can effectively reduce the frictional force of bracing piece 5 and connecting hole 7.
