Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a PVC cable protection pipe with crack resistance and impact resistance. Background Technique

[0002] Cable protection pipes are buried underground, in building wall structures, etc., to protect the cables inside, avoid their breakage and disconnection, and prevent the service life from being affected by environmental corrosion. Cable protection pipes are generally made of PVC resin as the main raw material and various stabilizers are added to form various specifications of rigid polyvinyl chloride pipes, which are used in telecommunications, power systems, etc. For general cable protection pipes, good protection can be achieved without special structural design. However, for some application scenarios, such as in extremely cold environments or places with relatively large vibrations, such as cable laying along railways, higher requirements for the impact resistance and crack resistance of cable protection pipes are needed, and special protection pipe structural designs are required.

[0003] As disclosed in the authorized publication number CN2122445089U, a PVC cable protection pipe with crack resistance and impact resistance is disclosed. It includes a PVC cable protection pipe body, a central composite sleeve is arranged in the middle of the PVC cable protection pipe body, there are two groups of central composite sleeves, and the two groups of central composite sleeves are sleeved and connected in sequence. Impact resistance components are arranged on the PVC cable protection pipe body, there are multiple groups of impact resistance components, and the multiple groups of impact resistance components are linearly arranged on the PVC cable protection pipe body. An anti-crack shock-absorbing ring sleeve is arranged between the two groups of impact resistance components. By linearly arranging multiple groups of impact resistance components on the PVC cable protection pipe body, the impact resistance ability is effectively increased. An anti-crack shock-absorbing ring sleeve is arranged between the two groups of impact resistance components, effectively forming a secondary shock-absorbing partition to improve the crack resistance on the surface of the cable sheath.

[0004] However, for the existing cable protection pipes currently, when protecting cables, they cannot reduce the conduction of impact force, resulting in excessive impact force on the internal cables and causing damage. At the same time, the sealing performance at the joints of the protection pipes is not high, and water seepage will occur in the underground humid environment, making the cables in a wet state for a long time, thus reducing the service life. Summary of the Invention

[0005] The purpose of the utility model is to provide a PVC cable protection pipe with crack resistance and impact resistance to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An anti-cracking and impact-resistant PVC cable protection pipe, comprising a pipe mechanism and a connection mechanism. The connection mechanism is located at both ends of the pipe mechanism. The pipe mechanism includes an outer protection pipe. Card slots are provided on the outer sides of both ends of the outer protection pipe. A corrugation is fixedly installed in the middle of the outer side of the outer protection pipe. Inner support rods are fixedly installed on the inner side of the outer protection pipe. A filling material is movably installed between the inner support rods. An inner protection pipe is fixedly installed on the inner side of the inner support rods. A metal material is fixedly installed in the inner protection pipe.

[0008] Preferably, the connection mechanism includes a pipe clamp. The pipe clamp is movably installed on the outer side of the outer protection pipe. A card pad is fixedly installed at the rear end inside the pipe clamp. The card pad is movably installed in the card slot.

[0009] Preferably, a ring clamp is movably installed on the outer side of the rear end of the pipe clamp. Clamping plates are fixedly installed at both ends of the ring clamp. Clamping holes are provided on the clamping plates.

[0010] Preferably, a clamping screw is movably installed in the clamping hole. A clamping nut is movably installed on the clamping screw.

[0011] Preferably, a connection disk is fixedly installed at the front end of the pipe clamp. Connection holes are provided on the connection disk. A connection screw rod is movably installed in the connection hole. A connection nut is movably installed on the connection screw rod.

[0012] Preferably, a connection pad is movably installed at the front end of the connection disk. A perforation is provided on the connection pad. A through hole is provided in the middle of the connection pad.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. For this anti-cracking and impact-resistant PVC cable protection pipe, anti-cracking materials are added to the inner protection pipe and the outer protection pipe to prevent the overall protection pipe from cracking. At the same time, the corrugation and the metal material can reduce the deformation of the outer protection pipe and the inner protection pipe. Moreover, the inner support rods support the inner protection pipe, so that when the outer protection pipe is impacted, large-area conduction is reduced, so that the internal cable will not be deformed and damaged. And the filling material can increase the frost resistance and increase the service life of the cable.

[0015] 2. For this anti-cracking and impact-resistant PVC cable protection pipe, it is clamped tightly by the card pad in the card slot and the connection gasket is clamped at the connection disk series connection, so that the protection pipe will not seep water, thus avoiding the cable being soaked in water and increasing the service life.

[0024] Through the above solution, the stability of the outer protective tube can be increased through the corrugation. When impacted, the corrugation makes the outer protective tube not easily deformed. The inner protective tube is supported by the inner support rods, so that when the outer protective tube is impacted, the impact force is prevented from being conducted to the inner protective tube over a large area. The metal material makes the inner protective tube not produce large deformations, so that the impact force will not cause the cables inside the inner protective tube to be deformed and damaged. The filling material can increase the frost resistance and the service life of the cables.

[0025] In this embodiment, preferably, the connecting mechanism 102 includes a pipe clamp 204, the pipe clamp 204 is movably installed outside the outer protection pipe 103, a cushion 205 is fixedly installed at the rear end inside the pipe clamp 204, and the cushion 205 is movably installed in the clamping groove 104.

[0026] Through the above solution, the pipe clamp can be sleeved outside the outer protection pipe for combination, and when the cushion is clamped into the clamping groove, the pipe clamp and the outer protection pipe can be sealed during combination.

[0027] In this embodiment, preferably, a ring clamp 206 is movably installed outside the rear end of the pipe clamp 204, clamping plates 301 are fixedly installed at both ends of the ring clamp 206, and clamping holes 302 are formed in the clamping plates 301.

[0028] Through the above solution, the clamping plates can be clamped through the clamping holes, so that the ring clamp is clamped outside the pipe clamp.

[0029] In this embodiment, preferably, a clamping screw 303 is movably installed in the clamping hole 302, and a clamping nut 304 is movably installed on the clamping screw 303.

[0030] Through the above solution, by movably installing the clamping screw through the clamping hole on the clamping nut, the ring clamp clamps the pipe clamp outside the outer protection pipe, and at the same time, the cushion and the clamping groove are tightly clamped.

[0031] In this embodiment, preferably, a connection plate 305 is fixedly installed at the front end of the pipe clamp 204, a connection hole 306 is formed in the connection plate 305, a connection screw 401 is movably installed in the connection hole 306, and a connection nut 402 is movably installed on the connection screw 401.

[0032] Through the above solution, the overall protection pipes can be connected in series through the connection plate and the connection hole, and by installing through the connection screw and the connection nut, the connection plate and the connection pad can be clamped and fixed.

[0033] In this embodiment, preferably, a connection pad 403 is movably installed at the front end of the connection plate 305, a perforation 404 is formed in the connection pad 403, and a through hole 405 is formed in the middle of the connection pad 403.

[0034] Through the above solution, the connection pad can ensure that there is no water seepage at the connection in series of the connection plates, the connection screw can pass through through the perforation, and the cable can be drawn through the through hole.

[0035] When an anti-cracking and impact-resistant PVC cable protection pipe of this embodiment is in use, the user sleeved the pipe clip 204 on the outer side of the outer protection pipe 103, so that the cushion 205 is clamped into the clamping groove 104, and then the ring clip 206 is movably installed on the outer side of the pipe clip 204. The clamping screw 303 passes through the clamping hole 302 on the clamping plate 301 and is connected to the clamping nut 304. By turning the clamping screw 303, the ring clip 206 is tightened to drive the cushion 205 to be clamped tightly with the clamping groove 104, and the outer protection pipe 103 is clamped by the pipe clip 204. After clamping, the connection disks 305 are connected in series. The connection screws pass through the connection holes 306 and the through holes 404 and are movably installed on the connection nuts 402, so that the connection disks 305 clamp the connection pieces and drive the overall protection pipe to be connected in series. After the series connection, the cable is inserted into the inner protection pipe 202. When the overall protection pipe is in use, anti-cracking materials are added to the inner protection pipe 202 and the outer protection pipe 103 to prevent the overall protection pipe from cracking. At the same time, the corrugations 105 can increase the stability of the outer protection pipe 103. When impacted, the corrugations 105 make the outer protection pipe 103 not easily deformed. At the same time, the inner support rods 106 support the inner protection pipe 202, so that when the outer protection pipe 103 is impacted, the impact force is prevented from being transmitted to the inner protection pipe 202 over a large area. And the metal material 203 in the inner protection pipe 202 makes the inner protection pipe 202 not generate large deformations, so that the impact force will not cause the cable inside the inner protection pipe 202 to be deformed and damaged. And the filling material 201 can increase the frost resistance and the service life of the cable.
