Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to a CPVC cable protection tube with a supporting structure. Background Art

[0002] Cable is a special kind of wire. Cable is usually a rope-like cable made of several or several groups of wires (at least two wires in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating coating. It is often installed in the air or underground or underwater for telecommunications or power transmission. CPVC pipe is a chlorinated polyvinyl chloride resin material. CPVC is a new type of engineering plastic with broad application prospects, and is often used in the manufacture of cable protection pipes.

[0003] The patent with publication number CN 213636958 U discloses a cpvc cable protection tube with good pressure resistance, which includes a tube body, a groove is opened on the top of the tube body, and a bolt is arranged through the top of the tube body. The device solves the problem that the existing cpvc cable protection tube cannot limit and fix the cable during use, which causes the cable to easily move and shake in the inner cavity of the protection tube. In addition, due to the single structure, the pressure resistance of the surface of the cable protection tube is poor, which causes damage when subjected to external pressure, thereby reducing the service life of the cable protection tube. However, the device has the problem that after the cable is placed in the tube body, the cable is fixed by the bolt thread and under the action of the first limit plate and the second limit plate. However, there are many types of cables in thickness, specifications and sizes, and it is difficult to use the bolt thread and the limit plate to fix them stably. Therefore, a CPVC cable protection tube with a support structure is proposed to solve the problem that the existing cable protection tube is difficult to stably fix and protect various types of cables.

[0028] The embodiment of the present application effectively solves the problem that it is difficult for existing cable protection tubes to stably fix and protect various types of cables by providing a CPVC cable protection tube with a support structure. Multiple installation sleeves together with fixing cones are placed at the required positions inside the cable protection tube body, and the cables are directly inserted into the cable protection tube body, passing through the multiple installation sleeves and fixing cones, cooperating with elastic slots, and using multiple fixing cones to expand and clamp the cables according to their sizes, so that the cables can be fixed inside the cable protection tube body.

[0029] Example

[0030] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing cable protection tube is difficult to stably fix and protect various types of cables. The overall idea is as follows:

[0031] In view of the problems existing in the prior art, the utility model provides a CPVC cable protection tube with a supporting structure, including a cable protection tube main body 1, the inner cavity of the cable protection tube main body 1 is provided with several groups of installation sleeves 2, the back of the installation sleeve 2 is fixedly connected with a fixed cone cylinder 3, the outer ring of the fixed cone cylinder 3 is provided with four groups of elastic notches 4, and the inner wall of the cable protection tube main body 1 is provided with a supporting structure 9. The multiple installation sleeves 2 together with the fixed cone cylinder 3 are placed in the required position inside the cable protection tube main body 1, and the cable is directly inserted into the cable protection tube main body 1, through the multiple installation sleeves 2 and the fixed cone cylinder 3, with the elastic notch 4, and the multiple fixed cone cylinders 3 are used to expand and clamp the cable according to the size of the cable, so that the cable can be fixed inside the cable protection tube main body 1, thereby solving the problem that the existing cable protection tubes are difficult to stably fix and protect cables of various types.

[0032] Among them, there is a large friction between the installation sleeve 2 and the cable protection tube body 1. The outer diameter and inner diameter of the bottom surface of the fixed cone 3 are the same as the outer diameter and inner diameter of the installation sleeve 2. The fixed cone 3 is divided into four parts by four groups of elastic grooves 4. The back end of the divided fixed cone 3 has a certain elasticity.

[0033] An anti-skid pad sleeve 5 is fixedly connected to the inner cavity wall of the fixed cone cylinder 3; wherein the anti-skid pad sleeve 5 is located on the inner cavity wall at the end of the fixed cone cylinder 3, and the inner circle of the anti-skid pad sleeve 5 is provided with anti-skid grooves 6; wherein the anti-skid grooves 6 are arranged in parallel on the inner circle of the anti-skid pad sleeve 5, and during the insertion of the cable, the anti-skid pad sleeve 5 in the inner cavity of the fixed cone cylinder 3 is cooperated to avoid direct contact with the surface of the fixed cone cylinder 3 during the process of clamping the cable, thereby preventing damage to the cable. At the same time, the anti-skid grooves 6 arranged in parallel are used to increase the friction between the fixed cone cylinder 3 and the cable, thereby preventing the cable from rotating randomly and improving the stability of the cable after it is fixed.

[0034] The front inner circle end of the mounting sleeve 2 is provided with a chamfer 7, and the front inner circle end of the anti-skid pad sleeve 5 is provided with a second chamfer 8. When the cable is inserted into the cable protection tube body 1 through the mounting sleeve 2 and the fixed cone 3, the chamfer 7 and the second chamfer 8 can prevent the cable from interfering with the thick boundary of the mounting sleeve 2 and the thick boundary of the anti-skid pad sleeve 5, thereby preventing the cable from being inserted.

[0035] The supporting structure 9 consists of a supporting groove 91, a reinforcing rib 92 and a reinforcing block 93; wherein, the front side of the cable protection tube body 1 is penetrated by a supporting groove 91, and a reinforcing rib 92 is arranged in the inner cavity of the supporting groove 91, the reinforcing rib 92 is in a triangular structure and is continuous, and a reinforcing block 93 is arranged in the gap of the reinforcing rib 92; wherein, the shape of the reinforcing block 93 is also triangular, and the cable protection tube body 1 is transformed into a double-layer structure under the action of the supporting groove 91, and the triangular reinforcing rib 91 and the reinforcing block 93 greatly enhance the supporting property of the cable protection tube, and even if the outer side of the protection tube is damaged, the internal cable is also difficult to be damaged, thereby improving the supporting property and safety of the cable protection tube.

[0036] Working principle: When it is necessary to use this CPVC cable protection tube with a supporting structure, place multiple installation sleeves 2 together with the fixing cones 3 into the required position inside the cable protection tube body 1, and then directly insert the cable into the cable protection tube body 1, through the multiple installation sleeves 2 and the fixing cones 3, cooperate with the elastic notch 4, and use multiple fixing cones 3 to stretch and clamp the cable according to the size of the cable, so that the cable can be fixed inside the cable protection tube body 1, solving the problem that the existing cable protection tube is difficult to stably fix and protect various types of cables; under the action of the support groove 91, the cable protection tube body 1 becomes a double-layer structure, and cooperates with the triangular reinforcement ribs 91 and reinforcement blocks 93, which greatly enhances the support of this cable protection tube. Even if the outside of the protection tube is damaged, the cable inside is also difficult to be damaged, thereby improving the support and safety of this cable protection tube.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
