Description

Technical Field

[0001] The utility model relates to the technical field of power pipe connection, and more specifically to a power pipe quick connection structure. Background Art

[0002] The power pipe is a pipe used to protect power lines and cables, usually made of plastic or metal. It can be used to protect wires from the external environment, and can also help to sort and organize wires. In actual use, multiple power pipes often need to be spliced ​​due to length requirements. At this time, a connection structure is required to fix multiple power pipes.

[0003] The existing power pipe connection structure still has the following problems: when installing the existing power pipe, two power pipes are often connected and fixed by bolts and clamps or welding. The connection is relatively complicated and requires the cooperation of multiple people, which undoubtedly increases the labor intensity of the personnel and has low installation efficiency, which brings many inconveniences to the use;

[0004] Secondly, when connecting multiple power pipes, if they are not completely aligned, gaps will exist at the joints of the multiple power pipes, which will undoubtedly affect the sealing effect of the joints of the power pipes. Long-term use will easily lead to external substances such as moisture and dust invading the interior of the power pipes, thereby affecting the normal operation of the wires and even causing short circuits or other faults, causing great trouble to actual use.

[0005] In view of this, we propose a power pipe quick connection structure. Utility Model Content
