[0001] The utility model relates to the technical field of glass fiber sleeves, in particular to an insulating, wear-resistant and high-temperature-resistant glass fiber sleeve. Background Technique
[0002] The glass fiber sleeve is a varnish tube of various insulation grades woven from glass fiber yarns into a blank tube and then coated with a resin material and heated and dried. There are PVC glass fiber tubes, silicone resin glass fiber tubes, acrylic glass fiber tubes, etc. The insulation grades include B grade, F grade, H grade, etc.
[0003] The existing patent CN215896073U, a document on an insulating, wear-resistant and high-temperature-resistant glass fiber sleeve, proposes that the utility model includes a first glass fiber sleeve. A fixing ring is fixedly connected to the inner wall of the first glass fiber sleeve. Two guide rods are symmetrically and fixedly connected to the side wall of the fixing ring. A second glass fiber sleeve is slidably inserted through the outer walls of the two guide rods. Two racks are symmetrically and fixedly connected to the outer wall of the second glass fiber sleeve. A fastening mechanism is provided between each rack and the first glass fiber sleeve. The fastening mechanism includes a bracket fixedly connected to the side wall of the first glass fiber sleeve. One end of the bracket away from the first glass fiber sleeve is fixedly connected to a circular shell. A gear is installed in the circular shell. A disc is fixedly connected to the outer wall of the gear. By screwing the fastening bolt in and out, the extension of the second glass fiber sleeve is realized, so as to achieve the effect of adjusting the length of the device, and greatly improve the use effect of the device.
[0004] However, although the existing patent CN215896073U realizes the extension of the second glass fiber sleeve by screwing the fastening bolt in and out, so as to achieve the effect of adjusting the length of the device and greatly improve the use effect of the device, when the blank tube woven from glass fiber yarns is used as the sleeve and is squeezed by the outside world, the problem that the cable inside the tube may be squeezed and deformed may occur. Content of the Utility Model

[0006] To achieve the above object, the present utility model provides the following technical solution: an insulating, wear-resistant and high-temperature resistant glass fiber sleeve, comprising a main body mechanism and an auxiliary mechanism.

When the wear-resistant outer tube is externally squeezed, the extrusion member squeezes towards the inside of the connecting member, and the roller slides along the inner wall of the connecting member, and the buffer spring contracts to shock-absorb the glass fiber sleeve body, effectively improving the safety of the sleeve.
[0009] Preferably, the silicon nitride layer is fixedly arranged at the inner end of the polyvinyl chloride layer, the boron carbide layer is fixedly arranged at the inner end of the silicon nitride layer, and the phenolic resin layer is fixedly arranged at the inner end of the boron carbide layer. The settings of the polyvinyl chloride layer and the phenolic resin layer improve the insulating effect of the sleeve, and the silicon nitride layer and the boron carbide layer improve the high-temperature resistant effect of the sleeve.
[0010] Preferably, the auxiliary mechanism includes a threaded connection port, a connecting sleeve, a sealing ring I and a sealing ring II. The threaded connection port is fixedly arranged at the outer end of the wear-resistant outer tube. The setting of the threaded connection port facilitates the lengthening of the sleeve.
[0011] Preferably, the connecting sleeve is movably installed inside the threaded connection port, and the connecting sleeve is threadedly connected to the wear-resistant outer tube. The threaded connection between the connecting sleeve and the wear-resistant outer tube facilitates the lengthening of the sleeve.
