Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, in particular to a carbon fiber sleeve. Background Art

[0002] At present, in order to prevent the laying of cables from being affected by external factors such as mechanical damage and chemical corrosion, a protective sheath is usually placed on the outside of the cable to extend the service life of the cable. Carbon fiber sheaths are used because of their excellent high temperature resistance, corrosion resistance and good insulation.

[0003] Existing carbon fiber sleeves for cables are usually produced by a weaving process and have better flexibility. However, it is not convenient to use glue bonding and hot-melt welding when connecting the braided carbon fiber sleeves. For this reason, we propose a carbon fiber sleeve. Utility Model Content

[0004] The utility model aims to provide a carbon fiber sleeve, which has the advantages of easy connection and disassembly of the braided carbon fiber sleeve and improved work efficiency, and solves the problem that the existing carbon fiber sleeves for cables are usually produced by a braiding process and have better flexibility, but the braided carbon fiber sleeves are not convenient to be connected by glue bonding and hot melt welding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbon fiber sleeve, comprising a carbon fiber braided sleeve and a carbon fiber rigid connecting tube, one end of the carbon fiber rigid connecting tube is located inside the carbon fiber braided sleeve, a rotating shaft is fixedly installed on the lower surface of the carbon fiber rigid connecting tube, two semicircular rings are rotatably installed at both ends of the rotating shaft, and four semicircular rings are provided with sockets at the ends, a fixed tube is fixedly installed on the upper surface of the carbon fiber rigid connecting tube, a spring is provided inside the fixed tube, and plug rods are fixedly connected to both ends of the spring.

[0006] Preferably, a fixing block is fixedly installed on the outer surfaces of the four semicircular rings near the insertion holes.

[0007] Preferably, annular grooves are symmetrically arranged on the outer surface of the carbon fiber rigid connecting tube near both ends, and protrusions are arranged on the inner walls of the four semicircular rings.

[0008] Preferably, the ends of the two insertion rods are both provided with rounded corners.

[0009] Preferably, both ends of the carbon fiber rigid connecting tube are provided with chamfers.

[0010] Preferably, a slide groove is provided on the upper surface of the fixed tube, and a shift block is fixedly installed on one side of the upper surface of the two insertion rods close to the spring, and the shift block is located inside the slide groove.

[0011] Preferably, a first clamping groove is provided at a middle position of the outer surface of the fixed tube, and the first clamping groove is communicated with the sliding groove.

[0012] Preferably, second clamping grooves are symmetrically arranged at both sides of the outer surface of the fixed tube, and the second clamping grooves are connected to the sliding grooves.

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

[0014] 1. The utility model achieves the effect of facilitating the connection and disassembly of the braided carbon fiber sleeves and improving work efficiency by arranging a carbon fiber rigid connecting tube, a carbon fiber braided sleeve, a rotating shaft, a semicircular ring, a socket, a fixed tube, a spring and a plug rod. When connecting the carbon fiber braided sleeves, the cable passes through the carbon fiber braided sleeve and the carbon fiber rigid connecting tube, and the two ends of the carbon fiber rigid connecting tube are respectively inserted into the two carbon fiber braided sleeves, and then the four semicircular rings are rotated, and the two semicircular rings form a group. The ends of each group of two semicircular rings are butt-jointed to form a complete circular ring, and are sleeved on the outer surface of the carbon fiber braided sleeve. When the socket and the plug rod are on the same axis, the plug rod is inserted into the socket to fix the semicircular ring, thereby completing the connection between the carbon fiber braided sleeves. When disassembling the carbon fiber braided sleeve, the plug rod and the socket are separated, and then the carbon fiber braided sleeve and the fixed tube are separated.

[0015] 2. The utility model achieves the effect of improving the connection strength between the carbon fiber braided sleeve and the carbon fiber hard connecting tube by setting the protrusion and the annular groove. After the protrusion is inserted into the annular groove, the carbon fiber braided sleeve is partially recessed and enters the annular groove, thereby improving the connection strength between the carbon fiber braided sleeve and the carbon fiber hard connecting tube.

[0016] 3. The utility model achieves the effect of facilitating the movement and fixation of the plug rod through the slide groove, the shift block, the first slot and the second slot. The plug rod is driven to move by shifting the shift block inside the slide groove. When the shift block is rotated to enter the first slot or the second slot, the plug rod can be fixed. When the shift block is located in the first slot, the plug rod is retracted into the fixed tube, which is convenient for the rotation of the semicircular ring and the docking of its ends. When the shift block enters the second slot, the movement of the plug rod is restricted to prevent the plug rod from slipping out of the socket. BRIEF DESCRIPTION OF THE DRAWINGS
