[0002] At present, heat shrink tubing is widely used for insulation, sealing and protection of various types of cables and the like. Heat shrink tubing is used by heating. In the prior art, a certain length of heat shrink tubing is wound into several turns for transfer and transportation. After winding, the turns of the heat shrink tubing easily slip against each other and become loose, causing the heat shrink tubing to become entangled with each other during transfer and transportation, which is not conducive to the use of the heat shrink tubing. In addition, due to the long and soft nature of the heat shrink tubing, the heat shrink tubing after heating and shrinkage has insufficient tensile strength in the length direction and is easily torn apart by a large external force, making it difficult to meet the application requirements of the heat shrink tubing. Utility Model Content

[0003] In response to the above-mentioned technical problems, the purpose of the utility model is to propose a heat shrink tubing assembly that facilitates the rolling of the heat shrink tubing, so that the rolling of the heat shrink tubing is neat and consistent, not messy, and can enhance the tensile strength of the heat shrink tubing, effectively meeting the actual application requirements of the heat shrink tubing.

[0004] The technical solution of the utility model is achieved as follows: a heat shrink tubing assembly includes a tubing body and a wire;

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] like Figure 1-8 The figure shows a heat shrinkable sleeve assembly described in this embodiment, which includes a sleeve body and a wire 2. The sleeve body 1 is a tubular structure, which is made of a heat shrinkable material. The heat shrinkable material is a conventional material in the prior art, and a polyolefin material can be selected. After the sleeve body 1 is formed, it is formed into a certain length, and the sleeve body 1 is straightened so that the sleeve body 1 has an extended state extending in a linear direction, and the sleeve body 1 is wound into a plurality of circles in sequence to form a rolled state. On the outer surface of the first side of the sleeve body 1, a plurality of recessed portions 12 are processed at intervals along the length direction thereof, and on the outer surface of the second side, a plurality of first raised portions 13 are processed at intervals along the length direction thereof. The above-mentioned recessed portion 12 is preferably a hole-like structure, and the first raised portion 13 is cylindrical. The aforementioned first side and second side are arranged on opposite sides of the sleeve body 1. During production, the sleeve body 1 is heated to a highly elastic state, a load is applied to expand it, and a mold is pressed downward to form the recessed portion 12 and the first raised portion 13. While the expansion is maintained and the mold is pressed downward, the sleeve body 1 is rapidly cooled to enter a glassy state, thereby fixing this state. When heated during use, the sleeve body 1 returns to a highly elastic state, allowing it to retract.

[0030] A hot melt adhesive layer is arranged on the inner wall of the sleeve body 1 to improve the shrink sealing effect of the sleeve body 1.

[0031] The recesses 12 and the first protrusions 13 are designed to have a certain spacing on the sleeve body 1. When the sleeve body 1 is in the aforementioned rolled state, at least one set of first protrusions 13 and recesses 12 that are matched and inserted with each other are arranged between the adjacent two turns of the sleeve body 1. Through the above structural design, the first protrusions 13 and the recesses 12 are inserted with each other, so as to limit the relative slippage between the adjacent two turns of the sleeve body 1. It should be noted that in the rolled state, the sleeve body 1 is flat. Since the sleeve body 1 has elasticity, when the first protrusions 13 and the recesses 12 are difficult to accurately align, the sleeve body 1 is slightly stretched, so that at least one set of first protrusions 13 and recesses 12 are accurately aligned and can be inserted. In addition, in actual application, when rolling, the first protrusions 13 that are not inserted between the adjacent two turns of the sleeve body 1 abut against the outer surface of the sleeve body 1 and slightly press down the outer surface of the sleeve body 1, so as not to interfere with the overall rolling state of the sleeve body 1.

[0032] In the embodiment, the wire 2 is a continuous long strip structure, which is made of a heat-shrinkable material. The heat-shrinkable material is a conventional material in the prior art, which can be polyolefin material. In specific actual design, the material of the sleeve body 1 and the material of the wire 2 are consistent, so as to have the same heat shrinkage rate. The wire 2 is processed with a plurality of through holes 22 and a plurality of second protrusions 21 along the length direction thereof. The spacing between each through hole 22 is matched with the spacing between each first protrusion 13. The spacing between each second protrusion 21 is matched with the spacing between each second protrusion 21. When the sleeve body 1 is in the straightened state, the wire 2 has a first combined state in which the through holes 22 are sleeved with each first protrusion 13, and a second combined state in which the second protrusions 21 are inserted with each recess 12. Through the above structural design, in the first combined state and the second combined state, the wire 2 is assembled to the sleeve body 1, and the two are length direction limit matched, and through the pulling of the wire 2, the tensile capacity of the sleeve body 1 in the length direction can be enhanced.

[0033] In this embodiment, a sinking space 11 is formed on the outer surface of the first side and the outer surface of the second side of the sleeve body 1. Both ends of the sinking space 11 extend along the length direction of the sleeve body 1. The sinking space 11 is a downwardly concave structure formed on the outer surface of the sleeve body 1. The width of the sinking space 11 is adapted to the width of the wire 2. The aforementioned recessed portion 12 and the first raised portion 13 are formed on the bottom surface of the sinking space 11. When the sleeve body 1 is in a straightened state, the aforementioned wire 2 is located in the sinking space 11, so that the wire 2 and the sleeve body 1 form an integral structure. When the sleeve body 1 is heated, the wire 2 and the sleeve body 1 shrink synchronously.

[0034] In terms of specific structural design, the aforementioned first raised portion 13 is internally hollow, and its wall thickness is consistent with that of the sleeve body 1. Furthermore, the aforementioned second raised portion 21 is internally hollow, and its wall thickness is consistent with that of the wire 2. This structural design ensures that the sleeve body 1 and the wire 2 have uniform thickness, maintaining consistency during contraction.

[0035] During specific use, when the heat shrinkable tube needs to be transferred and transported, the tube body 1 is wound into several turns to form a rolled state. In the rolled state of the tube body 1, the several raised portions and several recessed portions 12 of the adjacent turns of the tube body 1 are plugged into each other, thereby limiting the relative slippage between the adjacent turns of the tube body 1, which is beneficial to the rolling of the heat shrinkable tube. The heat shrinkable tube is rolled neatly and uniformly, not messy, and is convenient for the transfer and transportation of the heat shrinkable tube. When the heat shrinkable tube needs to be shrunk for use, the tube body 1 is pulled out from the rolled state and extended into a straight state, the tube body 1 is cut into the required length, and the wire 2 is assembled to the tube body 1. The wire 2 is then cut into the required length. The through hole 22 on the wire 2 is sleeved and matched with each first protrusion 13, and the second protrusion 21 on the wire 2 is plugged and matched with each recessed portion 12, so that the wire 2 and the sleeve body 1 are pulled and matched with each other in the length direction. After the sleeve body 1 and the wire 2 are heated and shrunk as a whole, the sleeve body 1 and the wire 2 form an integral structure, so as to enhance the overall tensile strength of the heat shrinkable sleeve, prevent the heat shrinkable sleeve from being torn by a large external force, and effectively meet the actual application requirements of the heat shrinkable sleeve.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
