Description

Technical Field

[0001] The utility model relates to the technical field of power cable protection, in particular to an assembled power cable protection tube. Background Art

[0002] Cable is an important carrier of communication technology. When it is installed or buried, a layer of cable protection must be covered on its surface. It will be protected by a protective tube. The power cable protection tube is an external protective pipe used to protect the integrity of the line and prevent damage from external forces.

[0003] In the prior art, a Chinese patent with publication number "CN214044843U" discloses an assembled power cable protection tube, which comprises a tube body, a mounting plate, a placement plate, a sliding rod, a pressure plate, a baffle, a support plate, a top plate, a pillar, a slide groove, a mounting rod, a slide plate, a spring, a push plate, a clamping plate, a transmission rod, a connecting rod, and a telescopic rod. After the cable is placed on the placement plate in the tube body, the pillar is pulled upward, and the pillar drives the top plate to move. The top plate drives two sliding rods to move through two transmission rods, and the two sliding rods drive two pressure plates to move to press the cable, thereby ensuring stable placement of the cable and being convenient to use. This solves the problem that most existing protection tubes are round in shape, are not stable enough to use, are inconvenient to place cables, and that the space inside the protection tube is too loose, resulting in unstable cable placement and inconvenient use.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] The power cable protection tube is an external protective tube used to protect the integrity of the line and from external damage. In order to make the protection tube convenient for protecting the power cable, most of the protection tubes are assembled. However, most of the assembled protection tubes cannot be spliced ​​together. A protection tube of a certain length cannot provide protection according to the length of the power cable. When the length is too long, it cannot protect the remaining exposed positions. When the power cable is too short, the overly long protection tube is a bit wasteful when used. Utility Model Content
