Technical Field

[0001] This utility model relates to the field of glass fiber sleeving technology, and in particular to a glass fiber sleeving with high insulation and bend resistance. Background Technology

[0002] Fiberglass sheathing is a tubular insulating and protective material made of fiberglass as the core substrate through processes such as weaving and impregnation. Its core characteristics are high temperature resistance, strong insulation, and a certain degree of mechanical strength. It is mainly used for high-temperature environment protection and insulation of wires, cables, and components. Fiberglass sheathing is mainly used in the fields of electronics, automotive, industrial manufacturing, and aerospace to provide high-temperature insulation and mechanical protection for wires and cables near heat sources, leads of high-temperature equipment, and circuits of precision components.

[0003] When workers need to protect electrical wires and cables, they put fiberglass sleeves over them to protect them. However, existing fiberglass sleeves may become damaged during use due to bending, which reduces their protective properties and may lead to electric shocks for workers when maintaining them. Utility Model Content

[0004] The purpose of this invention is to solve the problem of electric shock that occurs when workers maintain fiberglass sleeves in the prior art, and to propose a fiberglass sleeve that is highly insulating and resistant to bending.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highly insulating and bend-resistant fiberglass sleeve, comprising a main tube, an internal groove formed on the surface of the main tube, a protective device provided on the surface of the main tube, the protective device comprising a thickened ring fitted onto the surface of the main tube, an isolation sleeve fixedly connected between two thickened rings, the isolation sleeve fitted onto the surface of the main tube, a second insertion hole formed on the surface of the thickened ring, the second insertion hole being located on one side of the isolation sleeve, a first insertion hole formed on the surface of the main tube, the second insertion hole being aligned with the first insertion hole, the first insertion hole... An insert rod is internally connected to the second insertion hole. A magnetic block is fixedly connected to the top of the insert rod and placed on the surface of the thickened ring. The magnetic block is magnetically connected to the surface of the thickened ring. A threaded ring is threadedly connected to the surface of the thickened ring and placed on the surface of the magnetic block. A reinforcing component is provided between the two thickened rings. The reinforcing component includes an anti-bending strip and a stop block. The two ends of the anti-bending strip are fixedly connected to the surface of the thickened ring and the anti-bending strip is fixedly connected to the surface of the isolation sleeve. The anti-bending strip can cooperate with the thickened ring to achieve the purpose of supporting the anti-bending strip.

[0006] Preferably, the two ends of the anti-bending strip are fixedly connected with abutments, and the threaded ring is placed on the surface of the abutments. The abutments can cooperate with the anti-bending strip to restrict the threaded ring.

[0007] Preferably, the main tube is provided with a sealing device inside, the sealing device including a thickening layer, the thickening layer being fixedly connected to the inside of the main tube, the thickening layer being located on one side of the isolation sleeve, the thickening layer being able to cooperate with the main tube to achieve the purpose of protecting the cable.

[0008] Preferably, the main tube has a storage trough inside, the storage trough is located on one side of the thickened layer, the storage trough is connected to the built-in trough, and the storage trough can cooperate with the main tube to achieve the purpose of storing the expanding adhesive.

[0009] Preferably, a metal ring is fixedly connected to the surface of the thickened layer. The metal ring is located on one side of the storage tank and can cooperate with the thickened layer to achieve the purpose of dispersing the expanding adhesive.

[0010] Preferably, the surface of the main tube is provided with a feed inlet, which communicates with the storage tank. The feed inlet is located on one side of the metal ring and can cooperate with the main tube to facilitate the worker's injection of expanding adhesive.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a protective device, when a worker needs to protect the wires and cables, the worker pushes the thickened ring, which drives the anti-bending strip and the isolation sleeve. The isolation sleeve prevents water stains from contacting the surface of the main pipe, and the anti-bending strip restricts the bending of the main pipe. The worker inserts the plug into the first and second plug holes, and the magnetic block contacts the thickened ring and is attracted to the thickened ring. The worker rotates the threaded ring, which is threadedly connected to the surface of the thickened ring. When the threaded ring rotates to the designated position, the threaded ring abuts against the surface of the abutment block. By setting up the protective device, the wires and cables can be effectively protected, avoiding a reduction in the protective performance of the fiberglass sheath for the wires and cables, thereby reducing the risk of electric shock for workers when maintaining the fiberglass sheath.

[0012] 2. In this utility model, by setting a sealing device, when the worker needs to seal both ends of the main pipe, the worker inserts an expanding adhesive syringe into the feed port to spray expanding adhesive. The expanding adhesive comes into contact with the metal ring and disperses, entering the storage tank. Subsequently, the worker inserts the expanding adhesive syringe into other feed ports to inject expanding adhesive, filling the entire storage tank. The expanding adhesive dries together with the wires and cables, sealing both ends of the main pipe. By setting a sealing device, the worker can effectively and conveniently seal both ends of the main pipe, preventing water from entering the main pipe and thus improving the sealing performance of the main pipe.

[0016] The specific design and function of its protective device 3 and sealing device 4 will be explained in detail below.

[0017] In this embodiment: the protective device 3 includes a thickened ring 37, which is sleeved on the surface of the main pipe 1. An isolation sleeve 33 is fixedly connected between the two thickened rings 37, which is also sleeved on the surface of the main pipe 1. A second insertion hole 36 is opened on the surface of the thickened ring 37, which is located on one side of the isolation sleeve 33. A first insertion hole 34 is opened on the surface of the main pipe 1, and the second insertion hole 36 is aligned with the first insertion hole 34. An insertion rod 39 is inserted into the interior of the first insertion hole 34 and is inserted into the interior of the second insertion hole 36. A magnetic block 38 is fixedly connected to the top of the insertion rod 39 and is placed on the surface of the thickened ring 37. The magnetic block 38 is magnetically connected to the surface of the thickened ring 37. A threaded ring 31 is threadedly connected to the surface of the thickened ring 37 and is placed on the surface of the magnetic block 38. A reinforcing component is provided between the two thickened rings 37, which includes an anti-bending strip 32 and a stop block 35.

[0018] Specifically, the two ends of the anti-bending strip 32 are fixedly connected to the surface of the thickened ring 37, and the anti-bending strip 32 is fixedly connected to the surface of the isolation sleeve 33. The anti-bending strip 32 can cooperate with the thickened ring 37 to achieve the purpose of supporting the anti-bending strip 32.

[0019] Specifically, the two ends of the anti-bending strip 32 are fixedly connected to abutment blocks 35, and the threaded ring 31 is placed on the surface of the abutment block 35.

[0020] In this embodiment, the abutment 35 can cooperate with the anti-bending strip 32 to achieve the purpose of restricting the threaded ring 31.

[0021] In this embodiment: a sealing device 4 is provided inside the main pipe 1. The sealing device 4 includes a thickening layer 44, which is fixedly connected to the inside of the main pipe 1. The thickening layer 44 is located on one side of the isolation sleeve 33. The thickening layer 44 can cooperate with the main pipe 1 to achieve the purpose of protecting the cable.

[0022] Specifically, the main pipe 1 has a storage tank 41 inside, which is located on one side of the thickened layer 44 and is connected to the built-in tank 2.

[0023] In this embodiment, the storage tank 41 can cooperate with the main pipe 1 to achieve the purpose of storing the expanding adhesive.

[0024] Specifically, a metal ring 42 is fixedly connected to the surface of the thickened layer 44. The metal ring 42 is located on one side of the storage tank 41. The metal ring 42 can cooperate with the thickened layer 44 to achieve the purpose of dispersing the expanding adhesive.

[0025] Specifically, the surface of the main pipe 1 is provided with a feed inlet 43, which is connected to the storage tank 41 and is located on one side of the metal ring 42.

[0026] In this embodiment, the feed port 43 can be matched with the main pipe 1 to facilitate the worker's injection of expanding adhesive.

[0027] Working Principle: By setting up the protective device 3, when the worker needs to protect the wires and cables, the worker pushes the thickened ring 37, which drives the anti-bending strip 32 and the isolation sleeve 33. The isolation sleeve 33 prevents water stains from contacting the surface of the main pipe 1, and the anti-bending strip 32 restricts the bending of the main pipe 1. The worker inserts the insertion rod 39 into the first insertion hole 34 and the second insertion hole 36. The magnetic block 38 contacts the thickened ring 37 and is attracted to it. The worker rotates the threaded ring 31, which is threadedly connected to the surface of the thickened ring 37. When the threaded ring 31 rotates to the designated position, it abuts against the surface of the abutment block 35. By setting up the protective device 3, the wires and cables can be effectively protected, avoiding the damage caused by the fiberglass sheath. The reduced risk of electric shock during fiberglass sleeve maintenance is mitigated. Furthermore, the sealing device 4 allows workers to easily seal both ends of the main pipe 1. When sealing is required, the worker inserts an expansion adhesive syringe into the inlet 43 to spray expansion adhesive. The adhesive contacts the metal ring 42, disperses, and enters the storage tank 41. The worker then inserts the syringe into other inlets 43 to inject more adhesive, filling the storage tank 41 completely. The adhesive adheres to the wires and cables, sealing both ends of the main pipe 1. The sealing device 4 effectively facilitates sealing of both ends of the main pipe 1, preventing water ingress and improving its sealing performance.
