Description

Technical Field

[0001] This utility model relates to the field of braided mesh tube technology, and in particular to a high-temperature resistant braided mesh tube. Background Technology

[0002] In fields such as optical fiber communication cables, automotive equipment, railway tracks, military industry, shipbuilding and locomotive manufacturing, as well as general industrial manufacturing, there are wires that require double protection. During operation, equipment often experiences high-frequency or large-amplitude vibrations. During these vibrations, the wire harness can easily rub against the contacting equipment. Prolonged friction can damage the wire harness and cause equipment malfunctions. To protect the cables, braided mesh is used for wiring, so that the internal cables will not be damaged during vibrations, thus providing protection.

[0003] Utility model CN220325215U discloses a high-temperature resistant braided mesh tube, belonging to the field of tubing technology. It includes a tube body, with a collar fixedly installed at one end. The outer wall of the other end has several L-shaped inserts. The outer wall of the collar has several pouches for inserting the inserts. The outer wall of the tube body also has reinforcing parts to prevent the inserts from detaching from the pouches. With this utility model, when the tube body is insufficient in length, another tube body is fitted over the cable with one end of its insert facing the pouch end of the tube body. Then, the pouch is folded over, and several inserts are inserted into the pouches. The pouches limit the insertion of the inserts, making it difficult for the two tube bodies to separate, thus preventing gaps between the two braided mesh tubes, avoiding damage to the cable, and extending the cable's service life.

[0004] The connection between the insert plate and the bag in the network tube disclosed in the above utility model relies on the reinforcement of the strap, but the Velcro (hook side / rough side) may lose its stickiness after high temperature or repeated use, resulting in loose connection. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant braided mesh tube to solve the problem mentioned in the background art that the adhesive of the straps may decrease after high temperature or repeated use, resulting in loose connections.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant braided mesh tube, comprising a tube body, with a first sleeve and a second sleeve respectively provided at both ends of the tube body. The inner diameter of the first sleeve is adapted to the outer diameter of the second sleeve. The first sleeve is provided with a plurality of L-shaped connecting grooves, which penetrate one end of the first sleeve and are circumferentially distributed on the first sleeve. The outer curved surface of the second sleeve is provided with a plurality of connecting shafts circumferentially distributed, the height of which is the same as the depth of the L-shaped connecting grooves.

[0007] Preferably, a limiting ring is provided on the inner wall surface of the first sleeve, and the limiting ring contacts the end face of the second sleeve when the first sleeve is connected to the second sleeve.

[0008] Preferably, a movable ring is elastically provided at the end of the second sleeve away from the tube body, and the movable ring can contact the end face of the limiting ring when the first sleeve is connected to the second sleeve.

[0009] Preferably, the second sleeve has a groove at the end away from the tube body, and several springs are distributed around the circumference of the groove. The other end of the spring is connected to the moving ring.

[0010] Preferably, the inner wall of the groove is provided with a plurality of limiting blocks, and the moving ring is provided with a plurality of limiting grooves on its circumference, with the limiting blocks and limiting grooves being adapted to each other.

[0011] Preferably, the tube body, the first sleeve, and the second sleeve are all made of pollution-free ceramic fiber or basalt fiber.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, one end of the first sleeve of one mesh tube is aligned with one end of the second sleeve of another mesh tube, and the positions of the first and second sleeves are adjusted so that the connecting shaft is aligned with the inlet of the L-shaped connecting groove. Then, the second sleeve is inserted horizontally into the first sleeve, so that the connecting shaft enters the L-shaped connecting groove. When the insertion is blocked, the second sleeve is rotated, so that the connecting shaft rotates synchronously, thereby driving the connecting shaft to rotate to the end of the L-shaped connecting groove, thus completing the connection between the first and second sleeves and achieving a stable connection between the two mesh tubes. This mesh tube connection is simple to operate, requiring only insertion and rotation to achieve a stable connection between the two mesh tubes. It avoids the use of strap reinforcement in the prior art and effectively avoids the situation where the adhesion of the strap decreases after high temperature or repeated use, leading to loosening of the connection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A high-temperature resistant braided mesh tube includes a tube body 1, with a first sleeve 2 and a second sleeve 3 respectively provided at both ends of the tube body 1. The inner diameter of the first sleeve 2 is adapted to the outer diameter of the second sleeve 3. The first sleeve 2 is provided with a plurality of L-shaped connecting grooves 4, which pass through one end of the first sleeve 2 and are distributed circumferentially on the first sleeve 2. The outer curved surface of the second sleeve 3 is provided with a plurality of connecting shafts 5, the height of which is the same as the depth of the L-shaped connecting grooves 4.

[0021] When connecting two mesh tubes, the operator aligns one end of the first sleeve 2 of one mesh tube with one end of the second sleeve 3 of the other mesh tube, and adjusts the positions of the first sleeve 2 and the second sleeve 3 so that the connecting shaft 5 is aligned with the inlet of the L-shaped connecting groove 4. Then, the second sleeve 3 is inserted horizontally into the first sleeve 2, so that the connecting shaft 5 enters the L-shaped connecting groove 4. When the insertion is blocked, the second sleeve 3 is rotated, so that the connecting shaft 5 rotates synchronously, thereby driving the connecting shaft 5 to rotate to the end of the L-shaped connecting groove 4, thus completing the connection between the first sleeve 2 and the second sleeve 3, and thus completing the stable connection between the two mesh tubes. The operation of connecting the mesh tubes is simple, and a stable connection between the two mesh tubes can be completed by simply inserting and rotating. This avoids the use of the binding strap reinforcement method in the prior art and effectively avoids the situation where the binding strap loses its stickiness after high temperature or repeated use, resulting in loosening of the connection.

[0022] Specifically, in this embodiment, a limiting ring 6 is provided on the inner wall surface of the first sleeve 2. When the first sleeve 2 is connected to the second sleeve 3, the limiting ring 6 contacts the end face of the second sleeve 3, so that when the first sleeve 2 is connected to the second sleeve 3, the limiting ring 6 can contact the end face of the second sleeve 3, thereby providing support force to the end face of the second sleeve 3 by the limiting ring 6, thereby improving the connection stability between the first sleeve 2 and the second sleeve 3.

[0023] Specifically, in this embodiment, a movable ring 7 is elastically provided at the end of the second sleeve 3 away from the tube body 1. When the first sleeve 2 and the second sleeve 3 are connected, the movable ring 7 can contact the end face of the limiting ring 6, so that when the first sleeve 2 and the second sleeve 3 are connected, the movable ring 7 can be in close contact with the limiting ring 6 under the action of elastic force, thereby avoiding the situation where the connection between the first sleeve 2 and the second sleeve 3 is unstable.

[0024] Specifically, in this embodiment, a groove 8 is provided at the end of the second sleeve 3 away from the tube body 1, and several springs 9 are distributed around the circumference of the groove 8. The other end of the springs 9 is connected to the movable ring 7. Through the arrangement of the groove 8 and the springs 9, the movable ring 7 can be slidably connected to the second sleeve 3, so that the movable ring 7 always coincides with the center of the second sleeve 3, so as to facilitate the insertion of the movable ring 7 into the first sleeve 2 by moving the second sleeve 3.

[0025] Specifically, in this embodiment, a plurality of limiting blocks 10 are provided on the inner wall circumference of the groove 8, and a plurality of limiting grooves 11 are provided on the circumference of the moving ring 7. The limiting blocks 10 and the limiting grooves 11 are adapted to each other, so that the moving ring 7 can slide and connect in the horizontal direction in the groove 8 through the adaptation of the limiting grooves 11 and the limiting blocks 10, thereby avoiding vertical shaking when the moving ring 7 is inserted into the first sleeve 2, which would affect the insertion of the moving ring 7 into the first sleeve 2.

[0026] Specifically, in this embodiment, the tube body 1, the first sleeve 2, and the second sleeve 3 are all made of pollution-free ceramic fiber or basalt fiber. The use of ceramic fiber or basalt fiber materials enables the tube body 1, the first sleeve 2, and the second sleeve 3 to possess high-temperature resistance and safety in use, which helps to improve service life and reduce pollution.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
