Description

PVC cable protection tube Technical Field The utility model relates to the technical field of pipelines, in particular to a PVC cable protection tube. Background The cable protection tube is laid on the outer layer of the cable to prevent the cable from being damaged, has certain mechanical strength, and can prolong the service time and service life of the cable. But current cable protection tube is comparatively troublesome when connecting the installation, takes time and takes the labor, leads to the installation effectiveness low, and the leakproofness is not enough between the protection tube in addition, and inside the rainwater got into easily, makes the cable bubble in aqueous for a long time, causes the cable creepage easily. In order to solve the above problems, it is necessary to provide a novel cable protection tube, which combines the advantages of easy installation and good sealing property. Disclosure of Invention The utility model aims to provide a PVC cable protection tube, which solves the problems of low installation efficiency and low sealing performance of the cable protection tube in the prior art. In order to achieve the above purpose, the utility model provides a PVC cable protection tube, which comprises a tube body, wherein two convex rings are fixedly connected to the outer side wall of the tube body, the two convex rings are respectively and adjacently arranged with two ends of the tube body, one of the ends is provided with a connecting piece, the connecting piece comprises a housing and a sealing cylinder body which are coaxially arranged, at least one through groove which is arranged along the length direction of the housing is arranged on the housing, the through groove comprises a middle section and guide sections which are positioned at two ends of the middle section, a spring is arranged in the middle section, the natural length of the spring is smaller than the length of the middle section, the diameter of the guide section is smaller than the diameter of the spring, a drag hook is arranged in the guide section, one end of the drag hook is fixedly connected with the spring, the other end of the drag hook is relatively arranged with one side surface of the adjacent convex ring close to the middle section of the tube body, the sealing cylinder body is fixedly connected with the middle part of the inner wall of the housing, and the end surface of the sealing cylinder body is relatively arranged with the end surface of the end head. Preferably, slots matched with the end structures are arranged on two end surfaces of the sealing cylinder body. Preferably, the shell is provided with a fixing bolt, the bottom end of the fixing bolt extends into the guide section, and the draw hook is provided with a threaded hole matched with the fixing bolt in structure. Preferably, the sealing cylinder is made of rubber. Preferably, the seal cylinder is bonded to the housing. Preferably, two through grooves are arranged. Therefore, the PVC cable protection tube adopting the structure has the following beneficial effects: 1. The elasticity that can utilize the spring makes two draw hooks pull a protruding circle on two body respectively, and then realizes being connected between two body, improves the installation effectiveness between the body. 2. After two drag hooks pull a convex ring on two pipe bodies respectively, the ends of the two pipe bodies are respectively clung to the sealing cylinder body, so that the sealing connection between the two pipe bodies is realized, and the sealing performance between the pipe bodies is improved. 3. The stability of drag hook position can be increased by utilizing fixing bolts, and then the connection strength and sealing reliability between pipelines are improved. The technical scheme of the utility model is further described in detail through the drawings and the embodiments.
