Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary installation tools for heat shrink tubing, and in particular to an auxiliary installation device for heat shrink tubing. Background Technology

[0002] Heat shrink tubing is typically made with polyolefin as the base material. Hot air is passed through the laid polyethylene tube to expand it, and then it is cooled while still deformed. Fixing this deformed state creates the heat shrink tubing. Insulating heat shrink tubing is widely used in the power industry, automotive wiring harnesses, electronic components, communications, and marine waterproofing, especially in wire harnesses and other electrical cables. Because heat shrink tubing is tubular, it is easily cut to the appropriate thickness and length to meet specific application needs. The main steps for using heat shrink tubing are: 1. Selection: The heat shrink tubing should generally be slightly larger than the cable to be protected; 2. Threading: Cut a suitable length of heat shrink tubing and thread it onto the cable to be protected; 3. Heat shrinking: Use a heating tool to evenly heat one end of the heat shrink tubing, causing it to gradually shrink and complete the installation.

[0003] Many heat shrink tubings are now sold flat. When using heat shrink tubing for wiring protection, it is not only inconvenient to thread cables through, but the cut end of the cable can also easily puncture the heat shrink tubing, causing damage, wasting heat shrink tubing, and reducing installation efficiency. Summary of the Invention

[0004] In view of this, the present invention provides an auxiliary installation device for heat shrink tubing, which solves the technical problems mentioned in the background art.

[0005] This utility model solves the above problems through the following technical means:

[0006] The auxiliary installation device for heat shrink tubing of this utility model includes a hemispherical end, a hollow flared tube disposed on the cross-section side of the hemispherical end, and a laterally expandable elastic sleeve disposed at the end of the flared tube.

[0007] Preferably, the outer surface of the end of the flared tube is provided with an annular snap-fit ​​groove, and one end of the elastic sleeve is fixed in the snap-fit ​​groove by a snap-fit ​​connection structure or a binding connection structure.

[0008] Preferably, the flared tube is assembled from multiple sections of tubes with the same inclination angle, forming a detachable and assembleable structure.

[0009] Preferably, an elastic rubber ring is provided on the inner side of the open end of the elastic sleeve.

[0010] As a further improvement to the above technical solution, the end of the elastic sleeve is provided with a tightening rope for tightening the opening and for hanging and storing.

[0011] Preferably, the elastic sleeve is made of elastic fabric sewn together.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0013] The auxiliary installation device for heat shrink tubing of this utility model involves, in use, folding the elastic sleeve outwards and placing it on the outside of the flared tube. Then, the cut end of the cable is inserted from the flared end of the flared tube towards the hemispherical end. After insertion, the elastic sleeve is folded back to its original position to fix the cable to the auxiliary installation device described in this embodiment. Next, the heat shrink tubing is inserted from the hemispherical end. The spherical surface of the hemispherical end is the smaller end, which allows the heat shrink tubing to be easily opened. When passing through the heat shrink tubing, the spherical surface of the hemispherical end also prevents the exposed cut surface of the cable from scratching the heat shrink tubing, reducing waste and ensuring the installation efficiency and quality of the heat shrink tubing. After passing through the heat shrink tubing, the device is removed before proceeding with subsequent operations. Attached Figure Description

[0017] like Figures 1-3 , Hemispherical end-1, flared tube-2, elastic sleeve-3, tightening rope-4, cable-5. Detailed Implementation

[0018] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1 to 2 As shown: The auxiliary installation device for heat shrink tubing described in this embodiment includes a hemispherical end 1, a hollow flared tube 2 disposed on the cross-sectional side of the hemispherical end 1, and a laterally expandable elastic sleeve 3 disposed at the end of the flared tube 2.

[0021] In this embodiment, the auxiliary installation device for heat shrink tubing is used by flipping the elastic sleeve 3 outwards and placing it on the outside of the flared tube 2. Then, the cut end of the cable 5 is inserted from the flared end of the flared tube 2 into the hemispherical end 1. After insertion, the elastic sleeve 3 is flipped back to its original position to fix the cable 5 together with the auxiliary installation device. The heat shrink tubing is then inserted from the hemispherical end 1. The spherical surface of the hemispherical end 1 is the smaller end, which makes it easy to open the heat shrink tubing. When passing through the heat shrink tubing, the spherical surface of the hemispherical end 1 also prevents the exposed cut surface of the cable 5 from scratching the heat shrink tubing, reducing waste and ensuring the installation efficiency and quality of the heat shrink tubing. After passing through the heat shrink tubing, the auxiliary installation device is removed before proceeding with subsequent operations.

[0022] In this embodiment, the hemispherical end 1 and the flared tube 2 are typically made of wear-resistant hard metal, which can effectively prevent the metal cut end of the cable 5 from damaging its inner wall.

[0023] In practical applications, the flexible elastic sleeve 3 and the rigid flared tube 2 are usually connected in the following way: the outer surface of the end of the flared tube 2 is provided with an annular snap-fit ​​groove (not shown in the figure), and one end of the elastic sleeve 3 is fixed in the snap-fit ​​groove by a snap-fit ​​connection structure or a binding connection structure.

[0024] In a preferred embodiment of this invention, the flared tube 2 is assembled from multiple sections of tubes with the same tilt angle, forming a detachable and assembleable structure. The number of tubes can be selected according to the thickness of the cable 5 to assemble the flared tube 2, so that the auxiliary installation device described in this embodiment can adapt to cables 5 of various thicknesses and expand its application range.

[0025] In a preferred embodiment of this invention, an elastic rubber ring (not shown in the figure) is provided on the inner side of the opening end of the elastic sleeve 3. When the elastic sleeve 3 is fitted on the outside of the cable 5, the elastic rubber ring increases the friction force, thereby preventing the cable 5 from coming off.

[0026] As a further improvement of this embodiment, the end of the elastic sleeve 3 is provided with a tightening rope 4 for tightening the opening and hanging storage. After the elastic sleeve 3 is put on the outside of the cable 5, the tightening rope 4 is tightened to further fix the cable 5, thereby further preventing the cable 5 from coming off. After use, the tightening rope 4 can also be hung in the tool position for storage.

[0027] In practical applications, the elastic sleeve 3 is specifically made of elastic fabric sewn together.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
