[0002] PVC wire trough, that is, polyvinyl chloride wire trough, is generally called line trough, electrical wiring trough, wiring trough, etc. PVC wire trough is a kind of wire trough. There are many types of wire troughs. According to different materials, wire troughs are divided into many types according to the wiring equipment industry regulations. Commonly used ones are environmentally friendly flame retardant PVC wire trough, halogen-free PPO wire trough, halogen-free PC / ABS wire trough, steel and aluminum and other metal wire troughs, etc.

[0003] After the current PVC board is installed, when a line fault occurs and workers need to inspect it, they first need to open the slot cover as a whole. However, the existing snap-on extrusion connection is mostly used, and the opening process requires a certain pulling force. If the force is too small, it is inconvenient to open it, and if the force is too large, the slot cover is easily damaged, which makes it inconvenient to use for maintenance. In order to deal with the above problems and defects, there is an urgent need for a PVC cable duct that is easy to disassemble and repair. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a PVC wire duct that is easy to disassemble, assemble and repair, so as to solve the problem that after the existing PVC board is installed, when a line fails and a worker needs to check it, he first needs to open the duct cover as a whole, while the existing ones mostly use a snap-on extrusion connection, and a certain pulling force is required during the opening process. If the force is too small, it is inconvenient to open, and if the force is too large, the duct cover is easily damaged, which makes it inconvenient to use and repair.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a PVC wire trunking that is easy to disassemble and repair, including: a bottom plate 1 and a cover plate 2, the outer wall of the bottom plate 1 is provided with a groove 11, the inner wall of the groove 11 is rotatably connected to the side plate 12, the inner wall of the bottom plate 1 is fixedly equipped with a spring 13, and the provision of the spring 13 is conducive to supporting the side plate 12, thereby improving the firmness of its fixation, and the side of the spring 13 away from the bottom plate 1 is fixedly connected to the side plate 12; the outer wall of the cover plate 2 is provided with a circular groove 21, the inner wall of the circular groove 21 is fixedly equipped with a spring 22 that provides elastic force, and the end of the spring 22 away from the circular groove 21 is fixedly equipped with a bayonet 23, the top of the cover plate 2 is provided with a fixing groove 24, the inner wall of the fixing groove 24 is rotatably connected to a rotating shaft 25, and the end of the bayonet 23 close to the spring 22 A connecting rope 26 is fixedly connected, and one end of the connecting rope 26 away from the pin 23 is fixedly connected to the rotating shaft 25. A baffle 27 is clamped on the outer wall of the pin 23, and a hinge 28 is fixedly connected to the top of the baffle 27. The side of the hinge 28 away from the baffle 27 is fixedly connected to the cover plate 2, and the side of the baffle 27 close to the cover plate 2 is fixedly connected with a second elastic piece 29 providing elastic force, and the side of the second elastic piece 29 away from the baffle 27 is fixedly connected to the cover plate 2. The number of circular grooves 21, springs 22, pins 23 and connecting ropes 26 is two, and the two circular grooves 21, springs 22, pins 23 and connecting ropes 26 are symmetrically distributed on both sides of the rotating shaft 25. By limiting the number and position of the circular grooves 21, springs 22, pins 23 and connecting ropes 26, it is beneficial to improve the limiting effect of the baffle 27.

[0030] like Figure 1 and Figure 2As shown, a support plate 3 is fixedly assembled on the top of the base plate 1, a connecting block 4 is fixedly connected to the bottom of the cover plate 2, and the outer wall of the support plate 3 is snap-fitted with the inner wall of the connecting block 4. By providing the support plate 3 and the connecting block 4, it is beneficial to improve the stability of the connection between the base plate 1 and the cover plate 2, thereby improving the firmness of use when in use.

[0031] like Figure 1 and Figure 2 As shown, a through hole 5 is provided on the top of the cover plate 2, and the through hole 5 is a ventilation hole. The provision of the through hole 5 is helpful to improve the air permeability of the device, thereby improving the air permeability and heat dissipation effect of the device.

[0032] like Figure 1 and Figure 2 As shown, there are two baffles 27, and the outer walls of the two baffles 27 are provided with square holes 6. The provision of the square holes 6 facilitates the staff to pinch the baffles 27 during disassembly.

[0033] like Figure 2 and Figure 3 As shown, the groove 11 is in a "Z" shape. By limiting the groove 11, it is helpful to limit the side plate 12 to prevent the side plate 12 from rotating outward under the push of the spring piece 13.

[0034] The technical solution provided by the utility model is that when the bottom plate 1 is connected with the cover plate 2, the side plate 12 on the bottom plate 1 is clamped with the baffle 27 under the cover plate 2. The side plate 12 is pushed by the spring 13 to increase the outward power of the side plate 12. When the side plate 12 and the baffle 27 are squeezed against each other, the side plate 12 and the baffle 27 are clamped with each other, and then the clamping pin 23 is moved toward the baffle 27 by the spring 22 and clamped with the baffle 27. At this time, the baffle 27 is limited by the clamping pin 23, and the baffle 27 and the cover plate 2 are at 90 degrees, thereby completing the fixing. When it needs to be disassembled, it is only necessary to rotate the rotating shaft 25, and the rotating shaft 25 drives the connecting rope 26 and the clamping pin 23 to move to the depth of the circular groove 21. At this time, the baffle 27 can be rotated outward, so that the bottom plate 1 and the cover plate 2 can be separated.

[0035] The support plate 3 and the connection block 4 are provided to improve the stability of the connection between the bottom plate 1 and the cover plate 2, thereby improving the firmness of the connection when in use.
