DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-5 A flame-proof rubber protective sleeve comprises a sleeve body 1, the outer wall surface of the sleeve body 1 is provided with a flame-proof outer layer 2, the sleeve body 1 is provided with a sleeve opening 11, the outer wall surface of the flame-proof outer layer 2 is provided with a puncture-resistant outer layer 3, the outer wall surface of the puncture-resistant outer layer 3 is provided with a reinforcement cover plate 4, a sealing strip 41 is provided between the reinforcement cover plate 4 and the puncture-resistant outer layer 3, a threaded pin 5 is provided on the reinforcement cover plate 4, the inner wall surface of the sleeve opening 11 is provided with a first adhesive layer 6 and a second adhesive layer 7, the first adhesive layer 6 is provided with a first tear strip 61, and the second adhesive layer 7 is provided with a second tear strip 71. The sleeve body 1 is a commonly used rubber protective sleeve with high elasticity.

[0029] In detail, the sheath body 1 is an annular cylindrical structure as a whole, and the flame-retardant outer layer 2 is evenly arranged along the outer wall of the sheath body 1. The flame-retardant outer layer 2 is made of a phosphate flame-retardant coating material, which has excellent flame retardancy and flame retardancy, can improve the fire resistance level of the sheath body 1, and has strong corrosion resistance, is environmentally friendly and non-toxic, improves the flame retardancy and flame retardancy of the sheath body 1, and has high elastic reset performance.

[0030] Furthermore, the puncture-resistant outer layer 3 is evenly arranged along the outer wall surface of the flame-proof outer layer 2. The puncture-resistant outer layer 3 is made of elastic nylon material. The elastic nylon material has high elastic reset property and can perform tapping effect on the inner screw groove 31. It has excellent puncture resistance and good chemical resistance and weather resistance.

[0031] Furthermore, the front view of the sleeve opening 11 is a fan-shaped structural opening with an opening angle of five degrees. The sleeve opening 11 vertically penetrates the sheath body 1. Combined with the highly elastic sheath body 1, the sleeve opening 11 can be easily opened to prepare for later sleeve connection on the wire.

[0032] In more detail, an inner screw groove 31 is provided on the puncture-resistant outer layer 3, and the threaded pin 5 passes through the reinforcement cover plate 4 and the sealing strip 41 and is threadedly connected to the inner screw groove 31. An inner hexagonal groove 51 is provided on the threaded pin 5, and the threaded pin 5 can be conveniently rotated and disassembled by a hexagonal wrench.

[0033] In general, the reinforcement cover plate 4 and the sealing strip 41 are both arc-shaped long strip structures as a whole. The sealing strip 41 is made of highly elastic polyurethane silicone material. The top-view cross-sectional dimension of the sealing strip 41 is not less than the top-view cross-sectional dimension of the reinforcement cover plate 4. The highly elastic polyurethane silicone material has excellent sealing properties. When the threaded pin 5 is threadedly locked, the reinforcement cover plate 4 squeezes the sealing strip 41 to achieve comprehensive sealing of the socket opening 11.

[0034] The reinforcement cover plate 4 and the threaded pin 5 are both made of plastic steel, which is durable and insulating.

[0035] Finally, the first tear strip 61 is bonded to the surface of the first adhesive layer 6, and the second tear strip 71 is bonded to the surface of the second adhesive layer 7. The first tear strip 61 and the second tear strip 71 are both made of soft polyethylene PE material, have excellent toughness and softness, and have a smooth surface. They can be stably bonded to the first adhesive layer 6 and the second adhesive layer 7 respectively. The first tear strip 61 and the second tear strip 71 are disposable items.

[0036] Working method: By arranging the flame-retardant outer layer 2 structure on the outer wall surface of the sheath body 1, the flame-retardant and flame-proof performance of the sheath body 1 is improved as a whole.

[0037] Moreover, by providing the puncture-resistant outer layer 3 structure on the outer wall surface of the sheath body 1, it is effectively avoided that the outer surface of the sheath body 1 is directly penetrated by sharp hard objects, thereby improving the puncture resistance of the outer surface of the sheath body 1.

[0038] In addition, if it is necessary to sleeve the sheath body 1 on the outer wall of the wire that has been plugged into the preset device, take the hexagonal wrench, insert the hexagonal slot 51 and rotate it counterclockwise, the threaded pin 5 can be rotated and removed, and then the reinforcement cover plate 4 and the sealing strip 41 can be removed. Since the sheath body 1 is made of elastic material as a whole, the sleeve opening 11 can be pried open, and then the sheath body 1 is sleeved on the outer wall of the wire through the pried open sleeve opening 11, and then the first tear strip 61 and the second tear strip 71 are torn off, and then the sleeve opening 11 is closed, and the first adhesive layer 6 and the second adhesive layer 71 are used to seal the sheath body 1. The joint layer 7 is sealed and bonded for stable closure, and then the sealing strip 41 is covered on the outer wall of the sheath body 1 located at the sleeve opening 11, and then the reinforcement cover plate 4 is covered on the outer wall of the sealing strip 41, and finally the threaded pin 5 is passed through the reinforcement cover plate 4 and the sealing strip 41 and the threaded pin 5 is turned clockwise with the inner thread groove 31 by an inner hexagonal wrench, so that the sheath body 1 can be sleeved on the wire without unplugging the wire, thereby avoiding affecting the normal use of the equipment when the wire is directly unplugged, and improving the flexibility of the sheath body 1 sleeved on the wire.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
