Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a modified polypropylene cable protection pipe. Background Technology

[0002] With the rapid development of technology, cable protection pipes play a crucial role in cable laying and use, effectively preventing cables from being damaged by external mechanical forces such as digging, crushing, and impacts. When buried underground, the pipes can withstand the pressure from the soil above and vehicles on the ground, preventing the cable from deforming or breaking due to pressure. Inside buildings or in industrial sites, the pipes prevent cables from being scratched or impacted by construction tools or other objects, ensuring that the cable's insulation and conductors are not damaged.

[0003] In common cable protection conduits, the inner diameter of the conduit is usually not much different from the inner diameter of the cable to prevent the cable from shaking or bending inside. This makes it difficult to thread the cable through the end of the conduit, reducing the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a modified polypropylene cable protection pipe.

[0005] Therefore, this utility model provides a modified polypropylene cable protection tube, the main technical problem to be solved is that it is relatively difficult to insert the cable into the head of the protection tube.

[0006] Preferably, a modified polypropylene cable protection pipe includes a protection component, the protection component including a protective layer, a connecting component installed on the outer wall of the protective layer, the connecting component including a first movable ring, the inner wall of the first movable ring being movably connected to the outer wall of the protective layer, a guide component installed on the left side surface of the protective layer, the guide component including a first guide ring, the right side surface of the first guide ring being fixedly connected to the left side surface of the protective layer, a second guide ring being fixedly connected to the left side surface of the first guide ring, an elastic ring being fixedly connected to the outer wall of the second guide ring, a telescopic component installed on the left side surface of the first movable ring, the telescopic component including a telescopic rod, one end of the telescopic rod being fixedly connected to the left side surface of the first movable ring, the other end of the telescopic rod being fixedly connected to the second movable ring, and the surface of the second movable ring having an inclined groove.

[0007] Preferably, the inner wall of the inclined groove is in contact with the surface of the elastic ring, the outer wall of the first guide ring is in contact with the lower surface of the telescopic rod, the inner wall of the protective layer is fixedly connected to a support layer, and the inner wall of the support layer is fixedly connected to a heat insulation layer.

[0008] Preferably, the inner wall of the first movable ring is provided with a first groove, the outer wall of the protective layer is fixedly connected to a movable block, the movable block is located inside the first groove, and the right side surface of the movable block is fixedly connected to an elastic block.

[0009] Preferably, the inner wall of the first movable ring is provided with a second groove, and a second locking block is fixedly connected to the surface of the protective layer, the second locking block being located inside the second groove.

[0010] Preferably, the surface of the first movable ring is provided with a through hole, and the upper surface of the second locking block is fixedly connected with an indicator block, which is movably connected inside the through hole.

[0011] Preferably, a fixing component is installed on the left side surface of the first movable ring. The fixing component includes a fixing ring, the right side surface of which is in contact with the left side surface of the first movable ring, and a baffle is fixedly connected to the inner wall of the fixing ring. The right side surface of the baffle is in contact with the left side surface of the second movable ring.

[0012] Preferably, a third groove is formed on the right side surface of the fixed ring, and a first locking block is fixedly connected to the left side surface of the first movable ring, the first locking block being located inside the third groove.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a solution with the following beneficial effects.

[0014] (1) Compared with the prior art, this modified polypropylene cable protection pipe, through a first moving ring, an elastic ring, and a second moving ring, when the cable is inserted into the protective pipe, the first moving ring is grasped and pushed to the right, causing the first moving ring to slide to the right. The first moving ring drives the telescopic rod fixed on the left side of the first moving ring to move to the right, causing the second moving ring fixed at the end of the telescopic rod to move accordingly. At this time, the elastic ring located on the inner wall of the telescopic rod is in contact with the inner wall of the inclined groove. Because the elastic ring is elastic, it is initially in a contracted state when it is located on the right side of the inclined groove. When the second moving ring moves to the right, and the position of the elastic ring remains unchanged, the elastic ring moves to the left side of the inclined groove. Since the inclined groove is wider on the left and narrower on the right, when the elastic ring moves to the left side... The second guide ring, which is fixed to the inner wall of the elastic ring, expands in diameter upon rebound, making it easier to thread the cable. Because of its elasticity, it also expands in diameter along with the elastic ring. After threading, the first moving ring returns to its original position, and the elastic ring returns to its initial small diameter, adhering to the cable surface to prevent cable swaying. Compared to conventional devices, where the inner diameter of the protective tube is generally similar to the inner diameter of the cable to prevent swaying or bending inside the tube, making it difficult to thread the cable through the head of the tube and reducing its practicality, this device expands the diameter of the second guide ring during cable threading, facilitating the process and improving its usability.

[0015] (2) Compared with the prior art, this modified polypropylene cable protection pipe, through the through hole, the indicator block, and the second locking block, has a second groove inside the first moving ring during use. When it is necessary to fix the position of the first moving ring, the position of the first moving ring is moved so that the second locking block fixed on the surface of the protective layer engages into the interior of the second groove. The indicator block fixed on the surface of the second locking block protrudes from the through hole on the surface of the first moving ring. By observing the position of the indicator block in the through hole, it can be seen where the first moving ring is engaged. When the indicator block is at the rightmost position, the first moving ring is at the origin position, and it can be connected to other protective pipes. When the indicator block is at the leftmost position, the first moving ring is at the leftmost position, which is convenient for threading. Attached Figure Description

The connecting component 2 includes a first movable ring 201, the inner wall of which is movably connected to the outer wall of the protective layer 101. A guide component 3 is mounted on the left side surface of the protective layer 101. The guide component 3 includes a first guide ring 301, the right side of which is fixedly connected to the left side surface of the protective layer 101. A second guide ring 302, made of silicone, is fixedly connected to the left side surface of the first guide ring 301. An elastic ring 303 is fixedly connected to the outer wall of the second guide ring 302. A telescopic component 4 is installed on the left side surface of the first moving ring 201.

A slanted groove 403 is opened on the surface of the second moving ring 402. When threading the cable, the first moving ring 201 is held and pushed to the right, so that when the elastic ring 303 moves to the left side, it rebounds. The diameter of the second guide ring 302 increases along with that of the elastic ring 303, making it easier to thread the cable.

[0025] Example 2:

[0026] Depend on Figures 1-4 As shown, this utility model provides a modified polypropylene cable protection pipe.

[0027] The inner wall of the inclined groove 403 is in contact with the surface of the elastic ring 303, the outer wall of the first guide ring 301 is in contact with the lower surface of the telescopic rod 401, a support layer 102 is fixedly connected to the inner wall of the protective layer 101, the support layer 102 is made of high-density polyethylene, a heat insulation layer 103 is fixedly connected to the inner wall of the support layer 102, the heat insulation layer 103 is made of rock wool, the support layer 102 can provide support, and the heat insulation layer can prevent damage to the internal cables caused by excessively high or low temperatures, a first groove 202 is formed on the inner wall of the first moving ring 201, and a moving block 104 is fixedly connected to the outer wall of the protective layer 101. 104 is located inside the first groove 202. An elastic block 203 is fixedly connected to the right surface of the movable block 104. When the first movable ring 201 moves to the right, the elastic block 203 is squeezed back. When the first movable ring 201 moves to the left, the elastic block 203 rebounds, causing the first movable ring 201 to move back to its original position. A second groove 205 is formed on the inner wall of the first movable ring 201. A second locking block 207 is fixedly connected to the surface of the protective layer 101. The second locking block 207 is located inside the second groove 205. Moving the position of the first movable ring 201 allows the second locking block 207 fixed to the surface of the protective layer 101 to engage with the second groove 205. Inside the groove 205, a through hole 206 is provided on the surface of the first moving ring 201. By observing the position of the indicator block 208 in the through hole 206, the engagement position of the first moving ring 201 can be determined. When the indicator block 208 is at the far right, the first moving ring 201 is at its origin position, which allows for connection with other protective tubes. When the indicator block 208 is at the far left, the first moving ring 201 is in its far left position, facilitating wire threading. The indicator block 208 is fixedly connected to the upper surface of the second locking block 207, and the indicator block 208 is movably connected inside the through hole 206, on the left side of the first moving ring 201. A fixing component 5 is mounted on the surface. The fixing component 5 includes a fixing ring 501. The right side surface of the fixing ring 501 is in contact with the left side surface of the first moving ring 201. A baffle 502 is fixedly connected to the inner wall of the fixing ring 501. The right side surface of the baffle 502 is in contact with the left side surface of the second moving ring 402. A third groove 503 is formed on the right side surface of the fixing ring 501. A first locking block 204 is fixedly connected to the left side surface of the first moving ring 201. The first locking block 204 is located inside the third groove 503. The fixing ring 501 and the first moving ring 201 are connected by the engagement of the first locking block 204 and the third groove 503.

[0028] Working principle: When inserting the cable into the protective conduit, hold the first moving ring 201 and push it to the right, causing the first moving ring 201 to slide to the right. The first moving ring 201 drives the telescopic rod 401 fixed on the left side of the first moving ring 201 to move to the right, causing the second moving ring 402 fixed at the end of the telescopic rod 401 to move accordingly. At this time, the elastic ring 303 located on the inner wall of the telescopic rod 401 is in contact with the inner wall of the inclined groove 403. Because the elastic ring 303 is elastic, it is initially in a contracted state when it is located on the right side of the inclined groove 403. When the second moving ring 402 moves to the right, the position of the elastic ring 303 remains unchanged, and the elastic ring 303 moves to the left side of the inclined groove 403. Since the inclined groove 403 is wider on the left and narrower on the right, the elastic ring 303 rebounds when it moves to the left side, and its diameter increases. The second guide ring 302, which is fixed to the inner wall of the elastic ring 303, has a certain degree of elasticity, so it can follow the diameter of the elastic ring 303. The increased size makes cable threading easier. After threading, the first moving ring 201 returns to its original position, and the elastic ring 303 returns to its initial small diameter, fitting against the cable surface to prevent cable swaying. The first moving ring 201 has a second groove 205 inside. When it is necessary to fix the position of the first moving ring 201, the position of the first moving ring 201 is moved so that the second locking block 207 fixed on the surface of the protective layer 101 engages with the inside of the second groove 205. The indicator block 208 fixed on the surface of the second locking block 207 protrudes from the through hole 206 on the surface of the first moving ring 201. By observing the position of the indicator block 208 in the through hole 206, it can be seen where the first moving ring 201 is engaged. When the indicator block 208 is on the far right, the first moving ring 201 is at the origin position, which can be connected to other protective tubes. When the indicator block 208 is on the far left, the first moving ring 201 is in the leftmost position, which facilitates cable threading.
