Description

Technical Field

[0001] The utility model relates to the technical field of insulating sheaths, in particular to a highly elastic wire and cable insulating sheath. Background Technique

[0002] Highly elastic wires and cables can maintain stable performance under various bending, stretching, and twisting conditions, and are not easily broken or damaged. This characteristic enables highly elastic wires and cables to be widely used in fields such as industrial automation, mechanical equipment, and automobile manufacturing, providing great convenience for users' production and life. To improve the service life of highly elastic wires and cables, insulating sheaths are used for protection. Insulating sheaths are generally made of high-performance insulating materials. To ensure the protection effect of the insulating sheath on the wire and cable and its own service life, the insulating sheath generally has a relatively high thickness, and thus has the disadvantage of being difficult to bend. When protecting highly elastic wires and cables, it will cause greater interference to them, so the use effect is generally average. Content of the Utility Model

A spiral groove is provided on the outer arc surface of the wear-resistant sleeve, and a spiral groove is provided on the outer arc surface of the wear-resistant sleeve, which facilitates its own bending. The sheath has good flexibility, reduces the impact on the performance of highly elastic wires and cables, and at the same time, the sheath itself has a relatively high thickness, can provide good protection for highly elastic wires and cables, and has a good use effect.

[0006] Further, the number of the spiral grooves is 1-5, which facilitates the bending of the wear-resistant sleeve.

[0007] Further, spiral wires are wound inside the spiral grooves, which facilitates the winding and fixing of the wear-resistant sleeve.

[0008] Further, the width of the spiral wire is between one-third and one-half of the width of the spiral groove, ensuring that the spiral wire does not interfere with the bending of the wear-resistant sleeve.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-2, this embodiment provides a technical solution: a highly elastic wire and cable insulating sheath, including a wear-resistant sleeve 1;

[0019] Wear-resistant sleeve 1: An insulating sleeve 2 is provided inside it. The wear-resistant sleeve 1 is a polyvinyl chloride wear-resistant sleeve, and the insulating sleeve 2 is an ethylene propylene rubber insulating sleeve. An opening groove 1-3 is provided on the outer arc surface of the wear-resistant sleeve 1, and an opening groove 2-4 is provided on the outer arc surface of the insulating sleeve 2. The positions of the opening groove 2-4 and the opening groove 1-3 do not coincide. The end of the insulating sleeve 2 is movably clamped with the end of the wear-resistant sleeve 1. The highly elastic wire and cable passes through the opening groove 1-3 and the opening groove 2-4 and enters the inside of the insulating sleeve 2. The positions where the opening groove 2-4 and the opening groove 1-3 are provided do not coincide. The end of the insulating sleeve 2 at the opening groove 2-4 overlaps with the end of the wear-resistant sleeve 1 at the opening groove 1-3. A spiral groove 5 is provided on the outer arc surface of the wear-resistant sleeve 1. The number of spiral grooves 5 is 1-5. Different numbers of spiral grooves 5 are provided according to the diameter of the wear-resistant sleeve 1. The opening of the spiral groove 5 facilitates the bending of the wear-resistant sleeve 1. A spiral wire 6 is wound inside each spiral groove 5. The spiral wire 6 is wound into the spiral groove 5. The clamping blocks 8 at both ends of the spiral wire 6 are movably clamped with the card slots 7. The clamping block 8 restricts the rotation and removal of the spiral wire 6. The winding of the spiral wire 6 around the wear-resistant sleeve 1 can further restrict the opening of the opening groove 1-3, ensuring the firmness of the wear-resistant sleeve 1 in wrapping the highly elastic wire and cable. The width of the spiral wire 6 is between one-third and one-half of the width of the spiral groove 5. The spiral wire 6 does not fill the spiral groove 5 and does not interfere with the bending of the wear-resistant sleeve 1. Card slots 7 are provided at both the left and right ends of the spiral groove 5. Clamping blocks 8 are provided at both the left and right ends of the spiral wire 6. The clamping blocks 8 are all movably clamped with the laterally adjacent card slots 7. A clamping strip 12 is provided at the opening groove 2-4 on the outer arc surface of the insulating sleeve 2. A sealing groove 11 is provided on the inner arc wall of the wear-resistant sleeve 1. The clamping strip 12 is movably clamped with the sealing groove 11. The head of the clamping strip 12 is pressed into the inside of the sealing groove 11. The clamping strip 12 is a dovetail clamping strip, and the sealing groove 11 is a dovetail groove. During the pressing process, elastic deformation will occur between the clamping strip 12 and the sealing groove 11, which can ensure the sealing performance of the connection between the wear-resistant sleeve 1 and the insulating sleeve 2. Insertion posts 10 are evenly distributed on the outer arc surface of the insulating sleeve 2. Insertion slots 9 are evenly distributed on the inner arc wall of the wear-resistant sleeve 1. The insertion posts 10 are all movably inserted into the vertically corresponding insertion slots 9. The movable insertion of the insertion posts 10 into the insertion slots 9 positions the wear-resistant sleeve 1 and the insulating sleeve 2 axially, which can prevent the dislocation of the insulating sleeve 2 and the wear-resistant sleeve 1 during use.

[0020] The working principle of the highly elastic wire and cable insulation sheath provided by the present utility model is as follows: During use, the highly elastic wire and cable passes through the first opening groove 3 and the second opening groove 4 and enters the interior of the insulating sleeve 2. The positions where the second opening groove 4 and the first opening groove 3 are opened do not coincide. The end of the insulating sleeve 2 at the second opening groove 4 overlaps with the end of the wear-resistant sleeve 1 at the first opening groove 3. Then, the head of the clamping strip 12 is pressed into the interior of the sealing groove 11. The clamping strip 12 is a dovetail-shaped clamping strip, and the sealing groove 11 is a dovetail-shaped groove. During the pressing process, elastic deformation will occur between the clamping strip 12 and the sealing groove 11, thereby ensuring the sealing performance of the connection between the wear-resistant sleeve 1 and the insulating sleeve 2. At the same time, the plug post 10 is movably inserted into the slot 9 to axially position the wear-resistant sleeve 1 and the insulating sleeve 2, which can avoid the dislocation of the insulating sleeve 2 and the wear-resistant sleeve 1 during use. Then, the spiral wire 6 is wound into the interior of the spiral groove 5. The clamping blocks 8 at both ends of the spiral wire 6 are movably clamped with the clamping grooves 7. The clamping blocks 8 restrict the rotation and removal of the spiral wire 6. Winding the spiral wire 6 around the wear-resistant sleeve 1 can further restrict the opening of the first opening groove 3, ensuring the firmness of the wrapping of the wear-resistant sleeve 1 around the highly elastic wire and cable. The spiral groove 5 is provided on the surface of the wear-resistant sleeve 1, and the width of the spiral wire 6 is smaller than the width of the spiral groove 5. Therefore, the wear-resistant sleeve 1 can be bent conveniently, the sheath has good flexibility, reducing the impact on the performance of the highly elastic wire and cable. Moreover, the wear-resistant sleeve 1 itself has a relatively thick thickness, which can provide good protection for the highly elastic wire and cable.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
