Description

Technical Field

[0001] The utility model relates to the technical field of cold shrink sleeves, in particular to a novel elastic cold shrink sleeve. Background Art

[0002] At present, cold shrink tubing is made of elastomeric materials, which are injection-vulcanized in the factory, and then expanded and lined with plastic spiral supports to form components of various cable accessories. Because it shrinks at room temperature by elastic retraction force, rather than using fire to heat and shrink like heat-shrinkable cable accessories, it is commonly known as cold-shrinkable cable accessories.

[0003] At present, the cold shrink sleeve is wrapped around various cable accessory components by shrinking. During the wrapping process, the cold shrink sleeve is easily twisted, and the cold shrink sleeve is easily broken over a long period of time, thereby affecting the sealing of the cold shrink sleeve. Utility Model Content

[0004] The utility model provides a novel elastic cold shrink sleeve, which can prevent the cold shrink sleeve from rotating and twisting through threaded convex strips, anti-rotation strips and notches. The cold shrink sleeve is easy to break under long-term rotation and twisting, thereby affecting the sealing of the cold shrink sleeve.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a new type of elastic cold shrink sleeve, including:

[0006] A cold shrink tube body, wherein the inner wall of the cold shrink tube body is extended with a threaded convex strip, the outer wall of the cold shrink tube body is extended with a plurality of anti-rotation strips at equal distances along the circumferential surface, and the outer walls of the plurality of anti-rotation strips are provided with a plurality of notches at equal distances.

[0007] As a novel elastic cold shrink sleeve of the utility model, the spacing between the plurality of notches is set to mm~mm.

[0008] As a novel elastic cold shrink sleeve of the utility model, the plurality of anti-rotation strips are arranged in six.

[0009] As a novel elastic cold shrink sleeve of the utility model, the cold shrink tube body, the threaded convex strip and the plurality of anti-rotation strips are integrally formed.

[0010] As a novel elastic cold shrink sleeve of the utility model, the cold shrink tube body is configured as an elastic rubber tube made of silicone rubber, EPDM rubber or nitrile rubber.

[0011] As a novel elastic cold shrink sleeve of the utility model, the thread pitch of the thread convex strip is set to 40mm-60mm.

[0012] The utility model provides a novel elastic cold shrink sleeve, which has the following beneficial effects:

[0013] (1) The novel elastic cold shrink sleeve can prevent the cold shrink sleeve from rotating and twisting by means of the threaded convex strips, the anti-rotation strips and the notches. The cold shrink sleeve is prone to rupture under long-term rotation and twisting, thereby affecting the sealing performance of the cold shrink sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solution in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0018] See also Figure 1-2 The utility model provides a technical solution: a new type of elastic cold shrink sleeve, comprising:

[0019] The cold shrink tube body 1 has a threaded convex strip 2 extending from the inner wall thereof, a plurality of anti-rotation strips 3 extending equidistantly along the circumferential surface of the outer wall thereof, and a plurality of notches 4 equidistantly formed on the outer wall of the plurality of anti-rotation strips 3.

[0020] In the present embodiment: the threaded ridges 2 on the inner wall of the shrinkable tube 1 can support the support body inside the shrinkable tube 1 along the thread. At the same time, the threaded ridges 2 increase the wrapping of the shrinkable tube 1, making the wrapping tighter, and can also assist in the support and fixation of the support body. The multiple anti-rotation strips 3 can reduce the distortion of the shrinkable tube 1, and utilize the multiple notches 4 to reduce the extrusion force of the shrinkable tube 1 when it is bent, so as to protect the shrinkable tube 1.

[0021] Specifically, the spacing between the plurality of notches 4 is set to be 40 mm to 60 mm.

[0022] In this embodiment, the curvature is controlled by the spacing between the plurality of notches 4 .

[0023] Specifically, the number of the plurality of anti-rotation strips 3 is six.

[0024] In this embodiment, six anti-rotation strips 3 are arranged around the cold shrink tube body 1 to reduce the bending of the cold shrink tube body 1 .

[0025] Specifically, the cold shrink tube body 1, the threaded convex strip 2 and the plurality of anti-rotation strips 3 are integrally formed.

[0026] In this embodiment: the tube body 1, the threaded convex strip 2 and the plurality of anti-rotation strips 3 are integrally formed by cold shrinking.

[0027] Specifically, the cold shrink tube body 1 is configured as an elastic rubber tube made of silicone rubber, EPDM rubber or nitrile rubber.

[0028] In this embodiment: the material of the cold shrink tube body 1 is an elastic rubber tube made of silicone rubber, EPDM rubber or nitrile rubber, so as to ensure the shrinkage by elastic retraction force.

[0029] Specifically, the thread pitch of the thread convex strip 2 is set to 40 mm to 60 mm.

[0030] In this embodiment: the support body is supported stably by the spacing distance between the threads of the threaded convex strips 2.

[0031] When in use, the inner wall threaded ridges 2 of the cold shrink tube body 1 can support the support body inside the cold shrink tube body 1 along the thread. At the same time, the threaded ridges 2 increase the wrapping of the cold shrink tube body 1, making the wrapping tighter, and can also assist in supporting and fixing the support body. The multiple anti-rotation strips 3 can reduce the distortion of the cold shrink tube body 1, and utilize the multiple notches 4 to reduce the extrusion force of the cold shrink tube body 1 when bending, so as to protect the cold shrink tube body 1 and prevent the cold shrink tube from generating rotational distortion. The cold shrink tube is prone to rupture under long-term rotational distortion, thereby affecting the sealing of the cold shrink tube.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
