Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink sleeves, in particular to a heat shrink sleeve sealing and wrapping device. Background Art

[0002] In the fields of construction, electrical engineering and communications, wire pipes play a vital role. There may be some problems when using wire pipes, such as easy damage, poor insulation performance or inconvenient installation. In order to solve these problems, GDJ wire pipes came into being. They have better wear resistance, corrosion resistance and insulation performance, and are also easy to install and maintain. With the continuous development of electronic technology and communication technology, the requirements for wire pipes are getting higher and higher. When splicing two sections of wire pipes, heat shrink sleeves are used instead of traditional tape wrapping. Heat shrink sleeves are a new type of heat shrink sleeve patching material designed for buried and overhead steel pipeline welds, anti-corrosion and thermal insulation of pipes. It not only improves the quality of pipeline pre-buried, but also is very convenient to operate, greatly improving work efficiency.

[0003] After searching, a Chinese patent with application number CN202220507544.7 discloses a heat shrinkable sleeve with a telescopic buckle structure. The existing heat shrinkable sleeve does not have a structure for sealing and clamping with a telescopic buckle, which leads to reduced sealing and stability of the heat shrinkable sleeve during use, and causes dust and stains to enter the interior of the heat shrinkable sleeve from the gap between the heat shrinkable sleeve and the wrapped object, affecting the protection area of ​​the wrapped object. Therefore, by solving the problem that the existing heat shrinkable sleeve does not have a structure for sealing and clamping with a telescopic buckle, which leads to reduced sealing and stability of the heat shrinkable sleeve during use, and causes dust and stains to enter the interior of the heat shrinkable sleeve from the gap between the heat shrinkable sleeve and the wrapped object, affecting the protection area of ​​the wrapped object, the invention has the advantages of a sealing and clamping structure with a telescopic buckle, and improves the sealing and stability between the heat shrinkable sleeve and the wrapped object.

[0004] When the above-mentioned heat shrink sleeve is used on the connection of the pipe body, there are still some shortcomings. After the heat shrink sleeve is used to connect and shrink the two pipe bodies, the pipe body will vibrate due to external factors during the use of the pipe body. When the pipe body vibrates, the connection ports between the pipes will rub against each other and shake back and forth, which may cause the pipe to rub against the inner wall of the shrunk heat shrink sleeve during the friction and shaking process, and the inside of the heat shrink sleeve may be damaged due to long-term friction, thereby reducing the quality of the heat shrink sleeve, which may easily cause the heat shrink sleeve to crack, reduce the protectiveness of the heat shrink sleeve on the pipe connection, and also shorten the service life of the heat shrink sleeve, making it inconvenient to use.

[0032] As attached Figure 1-7 As shown, an embodiment of the utility model is provided: a heat shrink sleeve sealing and wrapping device, comprising a first tube body 1, a second tube body 2 is arranged at the left end of the first tube body 1, a heat shrink sleeve 3 is arranged on the outside of the first tube body 1 and the second tube body 2, a soft rubber ring 4 is arranged on the inner middle part of the heat shrink sleeve 3, a plurality of shells 5 are arranged inside the soft rubber ring 4, a protective shell 6 is slidably connected inside the shell 5, a buffer ring 10 is arranged outside the plurality of protective shells 6, a plurality of springs 7 are arranged inside the soft rubber ring 4, the other ends of the plurality of springs 7 are arranged outside the buffer ring 10, the left and right sides of the inside of the heat shrink sleeve 3 are provided with a plurality of springs 7, and the other ends of the plurality of springs 7 are arranged outside the buffer ring 10. Sealing rings 8 are provided at both ends, and sealing rings 9 are provided inside the sealing rings 8. The interiors of the two mounting blocks 11 at the upper and lower ends are slidably connected with mounting rods 15, and the exteriors of the two mounting rods 15 are fixedly connected with protective shells 13. The upper and lower ends of the protective shell 13 are fixedly connected with two threaded sleeves 14, and the internal threads of the threaded sleeves 14 are connected with bolts 16. The soft rubber ring 4 is made of silicone, and the outer shell 5 and the protective shell 6 are beneficial to reducing the impact force and protecting the spring 7, and the sealing ring 8 and the sealing ring 9 are beneficial to enhancing the sealing of the heat shrinkable sleeve 3.

[0033] As attached Figure 2 As shown, two mounting blocks 11 are provided at both upper and lower ends of the heat shrinkable sleeve 3, and a hole groove 12 is provided inside the top of the mounting block 11. The mounting block 11 is convenient for installing the corresponding mounting rod 15, and the hole groove 12 is convenient for the engagement of one end of the bolt 16, thereby facilitating the limiting of the mounting rod 15.

[0034] As attached Figure 1 As shown, the interiors of the two mounting blocks 11 at the upper and lower ends are slidably connected with mounting rods 15, and the exteriors of the two mounting rods 15 are fixedly connected with protective shells 13. The protective shells 13 are beneficial for protecting the heat shrinkable tube 3, thereby reducing the phenomenon of damage to the heat shrinkable tube 3 due to external factors.

[0035] As attached Figure 7 As shown, the outside of the heat shrinkable tube 3 is provided with an anti-corrosion layer 17, and the anti-corrosion layer 17 is made of epoxy resin to improve the anti-corrosion ability of the heat shrinkable tube 3, thereby facilitating the extension of the service life of the heat shrinkable tube 3. The outside of the anti-corrosion layer 17 is provided with a protective layer 18, and the protective layer 18 is made of high-density polyethylene.

[0036] As attached Figure 3 As shown, the buffer ring 10 is made of silicone, which is convenient for reducing the impact force. The sealing ring 8 and the sealing ring 9 are both made of hot melt adhesive, which is conducive to shrinking together with the heat shrinkable sleeve 3 due to heat shrinkage, thereby improving the sealing performance.

[0037] Working principle: when using heat shrink sleeves to splice pipes, first put the heat shrink sleeve 3 into the first tube body 1, and then put one end of the second tube body 2 into the other end of the heat shrink sleeve 3, and use a heating tool to heat the heat shrink sleeve 3 so that the inner wall of the heat shrink sleeve 3 is tightly attached to the connection between the first tube body 1 and the second tube body 2. When the first tube body 1 and the second tube body 2 shake during use, causing shaking at the connection port, the interface of the first tube body 1 or the second tube body 2 will hit the buffer ring 10 due to the shaking. Because the buffer ring 10 is made of silicone, the impact of the tube body hitting the silicone is easy to reduce the impact force, and the buffer ring 10 will squeeze the protective shell 6 at the corresponding force point when it is hit, so that the protective shell 6 slides inside the outer shell 5, thereby squeezing the spring 7, thereby through the spring 7 and the buffer ring 10 and the soft rubber ring 4. Under the action, it is beneficial to buffer the impact force generated by the first tube body 1 and the second tube body 2, thereby reducing the impact force, which is beneficial to protect the inner wall of the heat shrinkable sleeve 3 and reduce the damage of the heat shrinkable sleeve 3 caused by the vibration of the tube body. When the outside of the heat shrinkable sleeve 3 needs to be protected, the anti-corrosion layer 17 is first applied to the outside of the heat shrinkable sleeve 3, and then the protective layer 18 formed by the protective film is wrapped around the outside of the heat shrinkable sleeve 3, and then the two mounting rods 15 are slid to the inside of the multiple mounting blocks 11, so that the protective shell 13 is covered on the outside of the heat shrinkable sleeve 3, and then the bolt 16 is tightened inside the threaded sleeve 14, so that under the action of the spiral descent, the bolt 16 is dropped to the inside of the corresponding hole groove 12, so that the installed protective shell 13 is limited, which is beneficial to protecting the outside of the heat shrinkable sleeve 3.
