Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink tubes, in particular to a split type silicone rubber heat shrink tube. Background Art

[0002] Silicone rubber heat shrink tubing is a widely used material, mainly used for insulation protection of wires and cables. This heat shrink tubing is made of silicone rubber and has excellent temperature resistance, chemical resistance and electrical insulation properties, which enables it to maintain stability in a variety of environments. Silicone rubber heat shrink tubing can shrink after being heated and tightly wrap around the wire or cable to form a protective layer to prevent electrical failures and interference from environmental factors.

[0003] The split silicone rubber heat shrink tubing is an innovation of the traditional silicone rubber heat shrink tubing. It adopts an open-close design, that is, the tubing can be separated along its length and then closed around the cable. This design allows it to be easily installed on any part of the cable without having to start the tubing from one end of the cable. This split design greatly simplifies the installation process, especially in complex or dense wiring environments, and can be quickly maintained and replaced without disassembling the entire system. Although traditional silicone rubber heat shrink tubing is powerful, its installation process is often cumbersome, especially when the cable part that needs to be protected is not easy to access or the cable wiring has been completed. It takes a lot of time and labor to pass it from one end of the cable to the other. In addition, once the silicone rubber heat shrink tubing is installed, if the cable needs to be repaired or replaced, it usually needs to be cut or destroyed, which not only increases the maintenance cost, but also increases the complexity of the operation. The split silicone rubber heat shrink tubing is designed to solve these problems. It provides a more flexible and efficient solution. Utility Model Content

The first shrinkable tube is used to connect to the corresponding pipe part to provide structural support. The first pipe has a connection function and can be screwed with the corresponding accessories through its external thread. The outer thread is convenient for connection with the matching internal thread component to ensure tight combination. The second shrinkable tube is similar to the first shrinkable tube and is also used for connection and support. The second pipe is used to extend the connection line to increase the flexibility of the system. The reinforcement ring is used to improve the mechanical strength of the pipe to avoid deformation under pressure.

[0006] Preferably, a tightening tube is provided inside the second pipe, and the inner ring of the tightening tube is provided with internal threads.

The internal threads provide threaded connection points that match the external threads.

[0007] Preferably, the tightening tube is provided with several shrinkage seams in the length direction, and the outer ring of the tightening tube is provided with a sealing gasket. The shrinkage seams allow the tightening tube to elastically deform when subjected to external force to achieve a better sealing effect, and the sealing gasket provides additional sealing protection to prevent medium leakage.

[0008] Preferably, a steel belt is provided on the second pipe, and a plurality of notches are provided on the steel belt. The steel belt is used to fix and reinforce the structure, and the tightness can be adjusted through the notches thereon. The notches are used in conjunction with other mechanical components to enhance the stability of the structure.

[0009] Preferably, a hoop shell is provided at the right end of the second pipe, and a worm is provided inside the hoop shell. The hoop shell serves as the main bearing body to protect the internal mechanical structure from external interference. The worm plays a key role in the adjustment process and adjusts the pressure between the pipes by rotating.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The primary advantage of this split silicone rubber heat shrink tube is its high sealing performance.

This sealing technology is particularly suitable for liquid and gas transmission systems with strict requirements. The sealing gasket provides additional sealing protection to ensure that there will be no leakage under high pressure, thereby improving the safety and reliability of the system.

[0013] 2. The installation and maintenance process of the split silicone rubber heat shrink tube is simple and quick. Users can quickly compress and relax the tightening tube through simple rotation operations. This design not only saves installation time, but also greatly reduces the work intensity when pipeline maintenance or replacement is required. The coordinated use of steel belts and worms makes the adjustment work more precise and can adapt to various installation environments and requirements;

[0014] 3. The split silicone rubber heat shrink tube has outstanding advantages in terms of structural stability and durability. The tightening tube, steel belt and worm gear made of high-strength materials ensure that the entire device can maintain unchanged performance even under long-term load or harsh environment. The addition of anti-slip washers enhances the stability of operation and prevents loosening due to vibration or operational errors, thereby extending the service life of the equipment and reducing maintenance costs.
