Description

Technical Field

[0001] This utility model relates to the field of composite sleeve technology, and in particular to an environmentally friendly pure crystal composite sleeve with a prepositioning structure. Background Technology

[0002] Pure crystal composite sleeves are mainly used to protect pipes or equipment, especially in situations requiring insulation and temperature control. Through its special structural design, pure crystal composite sleeves can provide effective insulation and temperature control functions in extreme environments. Pure crystal composite sleeves can work stably in various complex environments. The installation and use of pure crystal composite sleeves cannot be separated from the cooperation of a pre-positioning device. Pre-positioning is of great significance in the use of pure crystal composite sleeves: (1) Improve installation efficiency: With the pre-positioning device, the installation between the sleeve and the pipe becomes more convenient and efficient. The staff does not need to spend time and effort aligning and fixing the sleeve and the pipe, which greatly shortens the installation time; (2) Ensure installation accuracy: The pre-positioning device ensures accurate alignment between the sleeve and the pipe, avoiding problems such as poor sealing and poor insulation effect caused by installation deviation; (3) Reduce installation risks: Without a pre-positioning device, deviation and shaking are likely to occur during the installation of the sleeve and the pipe, increasing the safety risks during the installation process. The use of the pre-positioning device effectively reduces these risks; (4) Enhance sleeve performance: Pre-positioning not only simplifies the installation process, but also helps to improve the insulation performance and service life of the sleeve. By ensuring a tight fit between the sleeve and the tube, heat loss and the influence of the external environment are reduced.

[0003] While existing pre-positioning devices for pure crystal composite sleeves have solved the alignment and fixation problems during sleeve and pipe installation to some extent, they often contain multiple components, such as locking blocks, fixing blocks, sliding rods, and springs. The combination of these components makes the overall device structure relatively complex. This complex structure not only increases manufacturing costs but may also affect the reliability and stability of the device. Due to the complex structure, it is prone to failure or wear during long-term use. Once a failure occurs, the cost of repairing and replacing parts may be high, increasing the operating cost. Furthermore, it requires a certain amount of installation space, which may impose certain limitations on the overall design of the sleeve and the operating environment.

[0004] Therefore, in view of the problems of the complex structure of the existing pure crystal composite sleeve and the high requirements for installation space, an environmentally friendly pure crystal composite sleeve with a pre-positioning structure can be designed. The structure is simpler and has no special requirements for installation space. The pre-positioning structure facilitates the alignment and fixing of the sleeve and the pipe. Utility Model Content

[0005] In order to overcome the problems of complex structure and high installation space requirements of existing pure crystal composite sleeves.

[0006] The technical solution of this utility model is as follows: an environmentally friendly pure crystal composite sleeve with a pre-positioning structure, including a sleeve and an inner tube, and further including a collar, a positioning locking component and a sliding pre-positioning component. A collar is fixedly connected to one end of the sleeve near the inner tube. A positioning locking component is fixedly connected inside the collar and is symmetrically distributed vertically. The positioning locking component includes an arc-shaped positioning seat with an insertion hole. A positioning locking rod is inserted into the insertion hole. A pull plate is fixedly connected to one end of the positioning locking rod away from the sleeve. A return spring is fixedly connected between the pull plate and the arc-shaped positioning seat. A sliding pre-positioning component corresponding to the positioning locking component is slidably connected to the outside of the inner tube. The sliding pre-positioning component includes a pre-positioning connecting block and a sliding block. The pre-positioning connecting block and the sliding block are fixedly connected. A first magnet is fixedly connected to one end of the sliding block near the sleeve. A positioning hole corresponding to the positioning locking rod is opened on the pre-positioning connecting block.

[0007] Preferably, the prepositioning connecting block, sliding block, and first magnet are pushed to the left. The sliding block moves to the leftmost end of the inner tube, aligning the prepositioning connecting block with the gap between the arc-shaped positioning seat and another arc-shaped positioning seat. Then, it is pushed towards the collar side, and the inner tube is rotated. The prepositioning connecting block pushes the positioning locking rod in the insertion hole, and the pull plate moves forward simultaneously. The return spring is stretched until the arc-shaped positioning seat is aligned with the prepositioning connecting block. Under the action of the return spring tension, the positioning locking rod is inserted into the positioning hole, fixing the arc-shaped positioning seat and the prepositioning connecting block. Then, the inner tube is pushed, and the sliding block and the inner tube slide relative to each other, inserting the inner tube into the sleeve.

[0008] Preferably, the sleeve includes an outer tube and an inner tube, with the inner tube fixedly connected to the inside of the outer tube, and a vacuum chamber provided between the outer tube and the inner tube.

[0009] Preferably, the return spring is sleeved on the outside of the positioning locking rod, and the arc length of the notch formed between the arc-shaped positioning seat and another arc-shaped positioning seat is greater than the arc length of the pre-positioning connecting block.

[0010] Preferably, the outer surface of the inner tube is provided with symmetrically distributed sliding grooves, and a second magnet is fixedly connected to the inner wall of the sliding groove near the sleeve. The second magnet and the first magnet are magnetically connected.

[0011] Preferably, the sliding block is slidably connected within the sliding groove, and the pre-positioning connecting block is slidably connected between the collar and the arc-shaped positioning seat.

[0012] Preferably, the collar cross-section is an "L" shaped structure, and the minimum inner diameter of the collar is greater than or equal to the inner diameter of the sleeve.

[0013] The beneficial effects of this utility model are as follows: By setting a pre-positioning device, convenient fitting and positioning of the composite sleeve and pipe are achieved, which not only improves installation efficiency but also effectively avoids damage to the sleeve or pipe that may occur during traditional installation, ensuring installation quality and safety. The use of magnets limits the two sliding blocks, avoiding the problem of inconsistent positions of the sliding blocks on both sides causing difficulty in positioning. In addition, a locking mechanism is provided to prevent the pre-positioning structure from loosening during installation. The overall structure is simple and reliable, which reduces manufacturing costs and reduces the stringent requirements for installation space, thus making it widely applicable to various installation environments and demonstrating extremely high flexibility and adaptability. By setting a vacuum chamber between the inner and outer layers of the sleeve, the thermal insulation performance of the sleeve is improved, meeting the thermal insulation requirements in special environments.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-4This utility model provides an embodiment: an environmentally friendly pure crystal composite sleeve with a pre-positioning structure, including a sleeve and an inner tube 2, and further including a collar 3, a positioning and locking assembly, and a sliding pre-positioning assembly. The collar 3 is fixedly connected to one end of the sleeve near the inner tube 2. A positioning and locking assembly symmetrically distributed vertically is fixedly connected inside the collar 3. The positioning and locking assembly includes an arc-shaped positioning seat 401, with an insertion hole 402 on the arc-shaped positioning seat 401. A positioning and locking rod 403 is inserted into the insertion hole 402, with the end of the positioning and locking rod 403 away from the sleeve... A pull-out plate 404 is fixedly connected, and a return spring 405 is fixedly connected between the pull-out plate 404 and the arc-shaped positioning seat 401. A sliding prepositioning component corresponding to the positioning locking component is slidably connected to the outer side of the inner tube 2. The sliding prepositioning component includes a prepositioning connecting block 501 and a sliding block 502. The prepositioning connecting block 501 and the sliding block 502 are fixedly connected. A first magnet 503 is fixedly connected to one end of the sliding block 502 near the sleeve. A positioning hole 504 corresponding to the positioning locking rod 403 is opened on the prepositioning connecting block 501.

[0021] Please see Figure 2 and Figure 4 In this embodiment, the sleeve includes an outer tube 101 and an inner tube 102. The inner tube 102 is fixedly connected to the inner side of the outer tube 101. A vacuum chamber 103 is provided between the outer tube 101 and the inner tube 102 to improve the heat preservation. The reset spring 405 is sleeved on the outside of the positioning locking rod 403. The arc length of the notch formed between the arc-shaped positioning seat 401 and another arc-shaped positioning seat 401 is greater than the arc length of the pre-positioning connecting block 501, ensuring that the pre-positioning connecting block 501 can pass between the arc-shaped positioning seat 401 and another arc-shaped positioning seat 401.

[0022] Please see Figure 3 and Figure 4 In this embodiment, the outer surface of the inner tube 2 is provided with symmetrically distributed sliding grooves 6. A second magnet 7 is fixedly connected to the inner wall of the sliding groove 6 near the sleeve. The second magnet 7 and the first magnet 503 are magnetically connected. The magnetic force of the two is used to fix the position of the sliding block 502. The sliding block 502 is slidably connected in the sliding groove 6. The pre-positioning connecting block 501 is slidably connected between the collar 3 and the arc-shaped positioning seat 401. The collar 3 has an "L" shaped cross section, and the minimum inner diameter of the collar 3 is greater than or equal to the inner diameter of the sleeve, ensuring that the collar 3 does not affect the installation of the inner tube 2 into the sleeve.

[0023] During operation, push the pre-positioning connecting block 501, sliding block 502, and first magnet 503 to the left. Sliding block 502 slides within the sliding groove 6, moving to the leftmost end of the inner tube 2. Under the action of the second magnet 7 and the first magnet 503, the stability of sliding block 502 is ensured, aligning the pre-positioning connecting block 501 with the gap between the arc-shaped positioning seat 401 and another arc-shaped positioning seat 401. Then push it towards the collar 3 side, rotating the inner tube 2. When the positioning locking rod 403 in the insertion hole 402 is pressed forward by the 501, the pull plate 404 moves forward simultaneously, and the return spring 405 is stretched until the arc-shaped positioning seat 401 is aligned with the pre-positioning connecting block 501. Under the action of the pull force of the return spring 405, the positioning locking rod 403 is inserted into the positioning hole 504, fixing the arc-shaped positioning seat 401 and the pre-positioning connecting block 501. Then, the inner tube 2 is pushed, and the sliding block 502 and the inner tube 2 slide relative to each other, so that the inner tube 2 is installed into the sleeve.

[0024] Through the above steps, by setting a pre-positioning device, convenient fitting and positioning of the composite sleeve and pipe are achieved, which not only improves installation efficiency but also effectively avoids damage to the sleeve or pipe that may occur during traditional installation, ensuring installation quality and safety. The use of magnets limits the two sliding blocks 502, avoiding the problem of inconsistent positions of the sliding blocks 502 on both sides causing difficulty in positioning. A locking mechanism is also provided to prevent the pre-positioning structure from loosening during installation. The overall structure is simple and reliable, which reduces manufacturing costs and reduces the stringent requirements for installation space, thus making it widely applicable to various installation environments and demonstrating extremely high flexibility and adaptability. By setting a vacuum chamber 103 between the inner and outer layers of the sleeve, the thermal insulation performance of the sleeve is improved, meeting the thermal insulation requirements in special environments; thus solving the problem of complex matching structures and high requirements for installation space in existing pure crystal composite sleeves.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
