Description

Technical Field

[0001] The utility model relates to the technical field of square corrugated power tubes, in particular to a square corrugated power tube that is easy to connect. Background Art

[0002] During the cable laying process, in order to protect the cable from damage by external forces and extend its service life, a cable protection tube is generally installed around the cable. By isolating the cable from the external environment, the cable is protected. Square corrugated tubes are one of the commonly used means.

[0003] The existing patent document CN213637026U proposes an MPP corrugated power tube that is easy to install, including a first tube body, a second tube body, a first fixing ring and a second fixing ring. The first tube body and the second tube body are arranged to have the same cylindrical structure. The first tube body and the second tube body are both sleeved with a first fixing ring and a second fixing ring on their outer peripheries. The first fixing ring and the second fixing ring are fixedly connected by two sets of locking bolts with nuts; two sets of buffer mechanisms are welded on the inner side walls of the first fixing ring and the second fixing ring, and the buffer mechanism includes a fixed cylinder, a movable rod and an arc block. The output ends of the first tube body and the second tube body are both inlaid with a plug, and the input ends of the first tube body and the second tube body are both provided with a slot that is compatible with the plug, and the inner wall of the slot is bonded with a sealing ring by adhesive. The MPP corrugated power tube that is easy to install has a simple structure and strong practicality.

[0004] However, since the prior art patent technology with publication number CN213637026U requires two sets of locking bolts with nuts to connect the power pipelines, the working steps are relatively cumbersome, which reduces the work efficiency. Utility Model Content

[0005] (1) Technical problems solved

[0006] The purpose of the present invention is to provide a square corrugated power pipe that is easy to connect, so as to solve the problem proposed in the above background technology that when connecting the power pipeline, two sets of locking bolts with nuts need to be used for connection, the working steps are relatively cumbersome, and the work efficiency is reduced.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: an easily connectable square corrugated power tube, comprising a corrugated power tube, a connector provided at the left end of the corrugated power tube, a connecting tube provided at the right end of the corrugated power tube, and a quick-connect mechanism provided inside the connecting tube;

[0009] Preferably, the quick-connect mechanism includes a reset spring, a connecting rod and a limit clamp. The reset spring is installed inside the connecting tube, the lower end of the reset spring is installed with a connecting rod, and the lower end of the connecting rod is installed with a limit clamp.

[0010] Preferably, a first steel wire reinforcement layer is provided at the inner end of the corrugated power tube, and a second steel wire reinforcement layer is provided below the first steel wire reinforcement layer.

[0011] Preferably, a waterproof layer is provided between the first steel wire reinforcement layer and the second steel wire reinforcement layer, and reinforcing ribs are provided on the inner wall of the corrugated power tube.

[0012] Preferably, the material of the corrugated power tube is flame-retardant modified polypropylene material, the outer shape of the corrugated power tube is a square wavy tube with a circular interior, and the shape of the limiting clamp is narrow on the right and wide on the left to facilitate the insertion of the connector.

[0013] Preferably, the first steel wire reinforcement layer and the second steel wire reinforcement layer are both steel wire mesh structures woven into a mesh.

[0014] Preferably, the waterproof layer is made of a colorless and transparent polyurethane synthetic polymer material, and the reinforcing ribs are arranged in a ring array on the inner wall of the corrugated power pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The easy-to-connect square corrugated power tube. When connecting the corrugated power tubes, the staff can insert the connector of one corrugated power tube into the connecting tube of another corrugated power tube. The setting of the limit clamp with a narrow right and wide left side facilitates the insertion of the connector. When the connector enters, it squeezes the limit clamp to shrink the reset spring. When the connector is installed in place, the reset spring loses the external pressure and drives the limit clamp to reset, thereby fixing the outer wall of the connector through several limit clamps, and finally completing the connection of the corrugated power tubes. This saves time and effort, and the connection can be completed with one plug, which improves work efficiency and enhances the practicality of the easy-to-connect square corrugated power tube.

[0017] 2. The easy-to-connect square corrugated power tube greatly improves the strength of the corrugated power tube by setting the first steel wire reinforcement layer and the second steel wire reinforcement layer, making the corrugated power tube not easy to be damaged. The setting of the waterproof layer effectively avoids the problem of water molecules penetrating into the interior of the corrugated power tube. The reinforcing ribs arranged in a circular array on the inner wall of the corrugated power tube further improve the compressive resistance of the corrugated power tube, thereby increasing the service life of the corrugated power tube and improving the use effect of the easy-to-connect square corrugated power tube.
