Description

Technical Field

[0001] The present invention relates to the technical field of insulating tubes, specifically an insulating tube and an insulating sleeve with such an insulating tube. Background Art

[0002] As the name implies, the function of the insulating tube is mainly used in the fields of motors, electrical appliances, radio, etc. for wiring insulation. The insulating tube itself has excellent dielectric properties and chemical resistance, and has excellent softness and elasticity. Generally, the insulating tube will be used in combination with an insulating sleeve, and the insulating sleeve protects the insulating tube. The insulating sleeve is characterized by high pressure resistance, light weight, and high corrosion resistance. However, the insulating tubes on the market still have the following problems:

[0003] 1. Most of the insulating sleeves and insulating tubes on the market are directly connected. Sometimes, when in use, there will be a pulling phenomenon, so that the insulating sleeve will be separated from the insulating tube, resulting in the insulating sleeve being unable to be fully connected to the insulating tube. Moreover, the fixing duration of tape fixing is limited and it is easy to fall off;

[0004] 2. Once the insulating sleeve encounters a pulling phenomenon during use, the internal structure will change, resulting in cracking and breaking, and it cannot be used continuously. A new insulating sleeve needs to be replaced, and it is very troublesome to replace the insulating sleeve, which is not conducive to the use of the insulating sleeve.

[0005] In view of the above problems, an innovative design is made on the basis of the original insulating sleeve. Summary of the Invention

[0029] An insulating sleeve with such an insulating tube comprises:

[0030] The insulating sleeve body 5 is located outside the insulating tube body 1 , and an adjusting mechanism 2 is arranged inside the insulating sleeve body 5 .

[0031] The adjustment mechanism 2 also includes an elastic insulating belt 201, a first spring 202, a limit block 203, a second spring 204, a linkage block 205 and a sliding block 206. The elastic insulating belt 201 is located on both sides of the insulating sleeve body 5. The elastic insulating belt 201 is composed of a wavy insulating sleeve body 5. One side of the sliding block 206 is connected to the second spring 204, one side of the second spring 204 is connected to the limit block 203, one side of the limit block 203 is connected to the first spring 202, and the other side of the sliding block 206 is connected to the linkage block 205.

[0032] Working principle: According to Figures 1-4 First, during the installation process, the insulating sleeve body 5 is wrapped around the insulating tube body 1 from the other side, and then the edge of the insulating sleeve body 5 is dragged to the position of the extension block 4, so that the undercut 304 and the auxiliary block 303 exceed the position of the extension block 4, and then the insulating sleeve body 5 is pulled in the opposite direction, so that the auxiliary block 303 drives the undercut 304 to be inserted into the interior of the extension block 4, and the undercut 304 and the extension block 4 are engaged with each other, and at the same time, the engaging block 301 enters the interior of the extension block 4 and completes the clamping work with the support rod 302;

[0033] according to Figures 1-5 As mentioned above, during use, when the insulating sleeve body 5 is pulled, the elastic insulating belt 201 stretches out. After the pulling force disappears, the second spring 204 pulls the sliding block 206 to enter the interior of the limit block 203.
