Description

Technical Field

[0001] The utility model relates to the technical field of protective pipe elbow structures, in particular to a cable protective pipe elbow structure. Background Art

[0002] PVC tubes are widely used as cable protection sleeves, and tubular elbows can be used in cable wiring applications. Currently, the common bending angles of elbows on the market include standard angles such as 30 degrees, 60 degrees, and 90 degrees.

[0003] During the use of ordinary PVC elbows on the market, the curvature of the elbow cannot be adjusted. In projects with high precision requirements, if elbows with other angles are required, they can only be customized from the manufacturer. This not only has a long production cycle, but also makes it difficult to cope with temporary changes in project requirements. Therefore, a cable protection tube elbow structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cable protection tube elbow structure comprises an elbow group, wherein the elbow group comprises an elbow, wherein two rubber tubes are symmetrically connected to the left and right sides of the elbow, and movable tubes are connected to the outer sides of the rubber tubes, and reinforcement components are arranged on the inner walls of the two movable tubes, wherein the reinforcement components comprise a fixing ring, and steel wire reinforcement ribs are inserted into the interior of the fixing ring, and a support component is arranged at the bottom end of the movable tube.

[0007] Preferably, three steel wire reinforcement ribs are provided, and the three steel wire reinforcement ribs are distributed around the inside of the movable tube. The steel wire reinforcement ribs are attached to the inner walls of the bent tube and the movable tube, so that the bent tube and the movable tube can be supported.

[0008] Preferably, the outer side of the movable tube is connected to a docking plate via threads, and a rubber ring is embedded in the docking plate. The rubber ring is embedded in the docking plate, and the rubber ring can constrain the cable.

[0009] Preferably, a fixing component is installed on the top of the movable tube, and the fixing component includes a threaded shaft, and the threaded shaft is inserted into the movable tube through a threaded hole. The end of the threaded shaft is rotatably connected to a rubber pressure block, and the cable is squeezed by the rubber pressure block to ensure the stability of the cable after being inserted into the movable tube.

[0010] Preferably, the rubber pressing block has an arc structure, and a partition plate is connected to the center of the bottom end of the rubber pressing block. The arc structure design of the rubber pressing block can provide better cable wrapping when the rubber pressing block is pressed downward.

[0011] Preferably, the supporting assembly includes a plate sleeve, the bottom end of the plate sleeve is connected to a support, the top end of the plate sleeve is provided with a support plate through a through groove, and the top end of the support plate is connected and fixed to the movable tube. Through the design of the support, the movable tube can be supported, thereby facilitating the placement of the movable tube.

[0012] Preferably, a threaded pin is inserted through a threaded hole on the outer side of the top end of the plate sleeve, and a friction block is rotatably installed on the end of the axis of the threaded pin, and the friction block abuts against the surface of the support plate through a groove, and is squeezed into the groove of the support plate through the friction block, thereby fixing the adjusted support plate.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting the elbow group and the reinforcement component, the bending processing of the elbow group is realized. Compared with the traditional structure, the device sets rubber tubes at both ends of the elbow to connect the rubber tube with the movable tube, so that the elbow and the movable tube can be bent freely. At the same time, a fixing ring is set on the inner wall of the elbow and the movable tube, and the steel wire reinforcement rib is passed through and fixed inside the fixing ring, so as to increase the toughness of the elbow, rubber tube and movable tube when connected together, and then meet the zero-time change requirements in the project.

[0015] 2. By setting a fixing component, the constraint and fixation of the inserted cables can be achieved. This device inserts multiple cables into the curved pipe, rubber tube and movable tube. By twisting and moving the threaded shaft, the two threaded shafts can be moved in the threaded holes of the two movable tubes respectively. During the movement of the threaded shaft, the rubber pressure block is pushed so that the rubber pressure block cooperates with the partition plate to press down and fix the cable, preventing the cable from loosening and detaching due to pulling after the insertion is completed.
