Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically a corrosion-resistant PE flame-retardant power cable protection pipe. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at intersections where communication cables and power lines cross. They prevent short circuits caused by power line breaks, which could energize communication cables and steel cables, thus protecting cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines.

[0003] Application number CN219322015U discloses an MPP power cable protection tube, relating to the field of power cable protection technology. This utility model includes an inner tube and a first outer tube. In practical use, the user pre-threads the power cable through the first, second, and third outer tubes. When the user rotates the first and second ferrules in opposite directions, the first and second outer tubes can move on the through-thread screws, thereby adjusting the distance between the first and second outer tubes, and the distance between the second and third outer tubes. This allows the user to use the protection tube for cables of different lengths. When the power cable is threaded through the first, second, and third outer tubes, the user connects the external screw through the base plate to the outside, allowing the protection tube to fix the power cable to the outside. However, in actual use, each adjustment of the position of the second and third outer tubes requires rotating multiple ferrules on the first and second ferrules, making the operation cumbersome.

[0008] In a preferred embodiment, the present invention can be further configured such that: two locking rings are located inside the two pull ropes respectively, the locking rings are T-shaped, the top of the locking rings are machined into a circular ring, and the bottom of the locking rings are machined into a short shaft.

[0009] In a preferred embodiment, the present invention can be further configured such that: both the fixed sleeve and the movable sleeve are equipped with wear-resistant rings, and the wear-resistant rings have multiple openings that are equally spaced and arranged in a ring.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple bolts are screwed onto the wear-resistant ring, the multiple bolts are arranged in pairs, forming three groups, and the three groups of bolts are respectively located inside multiple openings.

[0011] In a preferred embodiment, the present invention can be further configured such that the outer ends of multiple bolts extend into the interior of the fixed sleeve and the interior of the movable sleeve, respectively.

[0012] In a preferred embodiment, the present invention can be further configured such that: two threaded holes are provided on the fixed sleeve, and the two threaded holes are vertically symmetrical about the long rectangular bar.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the corrosion-resistant PE flame-retardant cable is passed through a fixed pipe sleeve and a movable pipe sleeve. Then, according to the length of the corrosion-resistant PE flame-retardant power cable, the position of the movable pipe sleeve is adjusted. The operator pulls the pull rope, and the included angle between the first transmission plate and the second transmission plate increases. Then, the movable pipe sleeve moves outward along the long rectangular bar. When the movable pipe sleeve reaches the appropriate position, the pull rope is tightly wrapped around the outside of the locking ring, thereby completing the fixation of the movable pipe sleeve. The steps are simple and convenient to use.

[0015] 2. In this utility model, when the wear-resistant PE flame-retardant cable passes through multiple wear-resistant rings, the inner wall of the wear-resistant ring is in contact with the outer wall of the cable.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a corrosion-resistant PE flame-retardant power cable protection pipe.

[0030] Example 1:

[0031] Combination Figure 1-5 As shown, the present invention provides a corrosion-resistant PE flame-retardant power cable protection pipe, including a locking mechanism 100 and an adjusting mechanism 200. The locking mechanism 100 includes a long rectangular bar 110, a fixed sleeve 120 sleeved on the outside of the long rectangular bar 110, and two movable sleeves 130 slidably connected to the long rectangular bar 110. The two movable sleeves 130 are respectively located on both sides of the fixed sleeve 120.

[0032] The distance adjustment mechanism 200 includes a hinge 210 disposed between the fixed sleeve 120 and the movable sleeve 130, a transmission plate 220 movably connected between the fixed sleeve 120 and the hinge 210, a transmission plate 230 movably connected between the movable sleeve 130 and the hinge 210, a pull rope 240 movably passing through the long rectangular bar 110 and connected to the hinge 210, and two locking rings 250 connected to the top of the long rectangular bar 110.

[0033] Furthermore, the two locking rings 250 are located inside the two pull ropes 240 respectively. The locking rings 250 are T-shaped, with the top end of the locking ring 250 machined into a circular ring and the bottom end machined into a short shaft.

[0034] Example 2:

[0035] Combination Figure 1 , 3 As shown in Figure 5, based on Embodiment 1, both the fixed sleeve 120 and the movable sleeve 130 are equipped with wear-resistant rings 300. The wear-resistant rings 300 have multiple openings, which are evenly spaced and arranged in a ring. The wear-resistant rings 300 can reduce the wear of the external corrosion-resistant PE flame-retardant cable when it passes through the fixed sleeve 120 and the movable sleeve 130, thus protecting the surface of the corrosion-resistant PE flame-retardant cable.

[0036] Furthermore, the wear-resistant ring 300 is screwed with multiple bolts 400, which are arranged in pairs to form three groups. The three groups of bolts 400 are located inside multiple openings, and the bolts 400 are provided to reinforce the wear-resistant ring 300.

[0037] Furthermore, the outer ends of multiple bolts 400 extend into the interior of the fixed sleeve 120 and the movable sleeve 130, respectively. The structural design of the bolts 400 enables them to firmly connect the wear-resistant ring 300 with the fixed sleeve 120 and the wear-resistant ring 300 with the movable sleeve 130.

[0038] Example 3:

[0039] Combination Figure 1-3 and Figure 5 As shown, in the above embodiment, the fixed sleeve 120 has two threaded holes 500. The two threaded holes 500 are vertically symmetrical about the long rectangular bar 110. The threaded holes 500 can reinforce the position of the fixed sleeve 120 and improve the stability of the device during use.

[0040] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the corrosion-resistant PE flame-retardant cable is passed through multiple wear-resistant rings 300. Then, according to the length of the corrosion-resistant PE flame-retardant power cable, the position of the movable sleeve 130 is adjusted. The operator pulls the pull rope 240, and then the included angle between the transmission plate 1 220 and the transmission plate 230 increases. Then the movable sleeve 130 moves outward along the long rectangular bar 110. When the movable sleeve 130 reaches the appropriate position, the pull rope 240 is wrapped tightly around the outside of the locking ring 250, thereby completing the fixation of the movable sleeve 130. The steps are simple and convenient to use.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
