Description

Technical Field

[0001] The utility model relates to the technical field related to PVC wire ducts, in particular to a PVC wire duct capable of preventing line bending. Background Art

[0002] PVC cables need to be fixed in cable ducts during installation, but the existing PVC cable ducts that prevent line bending still have certain defects when used, such as;

[0003] For example, a PVC cable trough for preventing line bending with publication number CN218449291U is provided with a connecting bolt, a connecting block and a connecting bolt, which are threadedly connected to the connecting bolt through a base, and the connecting bolt is symmetrically arranged about the vertical center axis of the base, the connecting block and the connecting rod are symmetrically arranged about the vertical center axis of the base, and the connecting plate is relatively snap-fitted and connected to the connecting block, the connecting block is symmetrically arranged about the vertical center axis of the support platform, and the connecting block is relatively snap-fitted and connected to the connecting plate, the connecting bolt is threadedly connected to the fixing block and the connecting plate, and the connecting bolt is equidistantly arranged on the fixing block, which is convenient for installation and disassembly of the PVC cable trough.

[0004] However, the anti-bending PVC cable duct still has the following disadvantages in actual use:

[0005] The installation is performed by threading the base and the connecting bolt relative to each other. In actual use, the threaded connection requires precise alignment and rotation, which not only increases the complexity and time of installation, but also usually requires specific tools, thereby increasing the preparation work and cost of installation. When the position of the cable duct needs to be replaced or adjusted as a whole, installation and disassembly are required multiple times, which increases the overall maintenance cost. In addition, multiple adjustments may cause the threaded connection to loosen, thereby affecting the stability of the cable duct.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original PVC cable duct that prevents line bending. Therefore, we proposed that the PVC cable duct that prevents line bending can solve the above problems well. Utility Model Content

[0007] The purpose of the utility model is to provide a PVC cable duct that prevents line bending, so as to solve the problem proposed in the above background technology that the base and the connecting bolt are installed relative to each other through threaded connection on the current market.
