Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink tubes, in particular to a quick-install heat shrink tube. Background Art

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing, also called EVA material. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. After searching, the prior art (publication number: CN220797703U) records "a quick-install heat shrink tube, belonging to the field of heat shrink tubes, a quick-install heat shrink tube comprising a tube body, a limit piece sleeved on the outer side of the tube body, and a sleeve provided on one side of the tube body, a straight tube sleeved on one side of the sleeve, an outer ring fixedly provided below the limit piece, a clip provided on the inner side of the outer ring, a first storage layer fastened and connected above the clip, a second storage layer provided on one side of the first storage layer, and a cable layer provided inside the tube body; at least two sets of limit pieces are sleeved on the outer side of the tube body, the outer ring is fixed to the outer wall of the tube body by cooperating with an arc-shaped pad, and the tightness of the inner ring is controlled by an elastic button, so that the inner ring and the cable layer are bound and fixed, the provided adhesive strip and the protruding edge are tightly fitted to the outer wall of the tube body, and the adhesive strip can be peeled off as needed to shrink preferentially due to heat and fit the component, thereby avoiding the heat shrink tube from being unstable and shifting."

[0003] Although the quick-install heat shrink tubing in the prior art achieves a fitted installation, it still has some shortcomings: when the existing quick-install heat shrink tubing is sleeved on the cable, the material of the heat shrink tubing is relatively soft and is deformed due to extrusion, which makes it difficult to quickly plug and install cables with similar outer diameters. Secondly, the heat shrink tubing is generally sleeved on the metal conductor connection of the cable to achieve insulation protection, and the outer diameter of the conductor connection of the cable is generally smaller than the cable body. After heating and shrinking, the heat shrink tubing will produce a depression at this place. At the same time, the conductor connection is only protected by a single heat shrink tubing, which makes it easy to break the skin and be damaged. Utility Model Content

[0004] In order to overcome the defects of the existing technology, a quick-install heat shrink tube is now provided to solve the problem that the existing quick-install heat shrink tube is still inconvenient to be installed with the cable and has a poor protection effect on the cable conductor connection.

[0005] To achieve the above-mentioned purpose, a quick-install heat shrink tube is provided, comprising: a quick-install part and a heat shrink tube body, the quick-install part is connected to one end of the heat shrink tube body, and the quick-install part includes a bell mouth on the outside, and a sleeve ring is connected to the inner side of the bell mouth, a connecting groove is provided on one end face of the sleeve ring, and an installation groove is provided on the inner ring wall of the sleeve ring, and a ball is installed inside the installation groove, one end of the heat shrink tube body is inserted into the connecting groove, and the inner wall of the heat shrink tube body is provided with a thickened hot melt adhesive wall and a hot melt adhesive convex ball.

[0006] Furthermore, the bell mouth and the sleeve ring are configured as an integrated structure made of metal material, and the inner narrow end diameter of the bell mouth is consistent with the inner ring diameter of the sleeve ring.

[0008] Furthermore, a locking bolt and an extrusion bolt are threadedly connected to the interior of the sleeve ring, and the inner end of the locking bolt is inserted into the inner ring wall of the limiting ring, and the inner end of the extrusion bolt is inserted into the connecting groove.

[0009] Furthermore, the outer wall of the heat shrink tube body is provided with identification rings at equal intervals along the length direction of the tube body, and the identification rings correspond to the inner and outer sides of the outer wall of the thickened hot melt adhesive wall.

[0010] Furthermore, the thickened hot melt adhesive wall and the hot melt adhesive convex balls are alternately arranged in the length direction of the heat shrinkable tube body, and the thickened hot melt adhesive wall is arranged as an arc block structure with equal intervals in the circumferential direction of the heat shrinkable tube body.

During the process, the ball installed on the inside of the sleeve ring allows the cable to be smoothly inserted into the heat shrink tube body, avoiding the increase in friction caused by the hot melt adhesive convex balls on the inner wall of the heat shrink tube body that affects the smoothness of the installation of the heat shrink tube. Then rotate the locking bolt to fix the cable in the sleeve ring, and you can achieve quick and smooth installation. It is especially suitable for situations where the outer diameter of the cable is not much different from the inner diameter of the heat shrink tube.

[0014] 2. When installing the heat shrink tube body, the inner thickened hot melt adhesive wall is placed at the metal conductor connection of the cable according to the outer identification ring, so that when heated and shrunk, the hot melt adhesive can be shrunk and fitted to thicken the metal conductor connection, thereby improving the insulation protection effect. After the heat shrink tube body shrinks due to heat, the extrusion bolt and the locking bolt can be loosened, and then the quick-install part can be taken out from one end of the cable and reconnected to one end of the heat shrink tube body to be used, thereby achieving a recycling effect.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 4 As shown, the utility model provides a quick-install heat shrink tube, including: a quick-install component 1 and a heat shrink tube body 2, the quick-install component 1 is connected to one end of the heat shrink tube body 2, and the quick-install component 1 includes an outer bell mouth 11, and the inner side of the bell mouth 11 is connected to a sleeve ring 12, one end face of the sleeve ring 12 is provided with a connecting groove 121, and the inner ring wall of the sleeve ring 12 is provided with a mounting groove 122, and a ball 15 is installed inside the mounting groove 122, one end of the heat shrink tube body 2 is inserted into the connecting groove 121, and the inner wall of the heat shrink tube body 2 is provided with a thickened hot melt adhesive wall 22 and a hot melt adhesive convex ball 23.

[0022] In this embodiment, the quick-install component 1 and the heat shrink tube body 2 constitute the main structure of the quick-install heat shrink tube involved in this application. Before installation with the cable, the quick-install component 1 and the heat shrink tube body 2 are in an integrated structure. After installation with the cable and the heat shrinkage effect is achieved, the quick-install component 1 can be disassembled for recycling.

[0023] It should be noted that, under normal circumstances, the material of the heat shrink tube is relatively soft, and the port cannot remain in a round state after being squeezed. At this time, the quick-release part 1 is used to open and fix its port, which greatly improves the efficiency of connecting with the cable, especially when the inner diameter of the heat shrink tube is slightly larger than the outer diameter of the cable.

[0024] Specifically, the connecting groove 121 is configured as an annular groove structure, and the groove width of the connecting groove 121 is greater than the wall thickness of the heat shrink tube body 2 .

[0025] It should be noted that when the heat shrink tube body 2 is actually connected to the connection groove 121 , it is only necessary to fix the end of the heat shrink tube body 2 in the connection groove 121 , and no requirement is placed on the flatness after the connection.

[0026] like Figure 2 and Figure 3 As shown, the bell mouth 11 and the sleeve ring 12 are set as an integrated structure of metal material, and the internal narrow end diameter of the bell mouth 11 is consistent with the inner ring diameter of the sleeve ring 12. The inner wall of the sleeve ring 12 is provided with a limit ring 16, and the limit ring 16 is provided with a limit hole along its radial direction, and the outer side of the ball 15 protrudes from the limit hole. The inner diameter of the circle surrounded by the balls 15 is larger than the inner diameter of the heat shrink tube body 2, and the balls 15 are rollingly embedded in the mounting groove 122. The interior of the sleeve ring 12 is screwed with a locking bolt 13 and an extrusion bolt 14, and the inner end of the locking bolt 13 is inserted through the inner ring wall of the limit ring 16, and the inner end of the extrusion bolt 14 is inserted into the connecting groove 121.

[0027] Specifically, the balls 15 roll in the limiting holes in the limiting ring 16 at the same time, so that when connected with the cable, the effect of friction is reduced, and the cable can be smoothly inserted into the heat shrink tube body 2.

[0028] like Figure 1 and Figure 4 As shown, the outer wall of the heat shrinkable tube body 2 is provided with identification rings 21 at equal intervals along the length direction of the tube body, and the identification rings 21 correspond to the inner and outer sides of the outer wall of the thickened hot melt adhesive wall 22. The thickened hot melt adhesive wall 22 and the hot melt adhesive convex balls 23 are alternately arranged in the length direction of the heat shrinkable tube body 2, and the thickened hot melt adhesive wall 22 is arranged as an arc block structure with equal intervals in the circumferential direction of the heat shrinkable tube body 2.

[0029] Specifically, the thickened hot melt adhesive wall 22 and the hot melt adhesive convex ball 23 shrink together when the heat shrink tube body 2 is heated, thereby wrapping the cable, and by providing an identification ring 21 on the outside of the thickened hot melt adhesive wall 22, the position can be placed at the connection of the cable conductor, which is convenient for later maintenance.

[0030] When in use, one end of the heat shrink tube body is clamped in the connecting groove, and then the extrusion bolt is tightened to fix the heat shrink tube body. Then, one end of the flare of the quick-install part is aligned with one end of the cable, and the cable is inserted into the flare. During the process, the ball installed on the inner side of the sleeve ring allows the cable to be smoothly inserted into the heat shrink tube body, avoiding the increase in friction caused by the hot melt adhesive convex balls set on the inner wall of the heat shrink tube body to affect the smoothness of the installation of the heat shrink tube. Then, the locking bolt is rotated to fix the cable in the sleeve ring, and quick and smooth installation can be achieved. When installing the heat shrink tube body, the inner thickened hot melt adhesive wall is placed at the metal conductor connection of the cable according to the outer identification ring, so that when heated and shrunk, the metal conductor connection can be shrunk, fitted and thickened by the hot melt adhesive, thereby improving the insulation protection effect.

[0031] The quick-install heat shrink tube of the utility model can effectively solve the problem that the existing quick-install heat shrink tube still has the inconvenience of being installed with the cable and the problem of deviation in the protection effect of the cable conductor connection. It further improves the installation convenience of the heat shrink tube on the basis of the existing quick-install heat shrink tube technology, and at the same time strengthens the protection effect of the cable connection.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
