Description

Technical Field

[0001] This utility model relates to the field of cold chain transportation technology, specifically a cold box with a novel connection structure. Background Technology

[0002] Cold chain transportation refers to transportation in which the goods are kept at a certain temperature throughout the entire transportation process, including loading and unloading, changing transportation methods, and replacing packaging equipment. Cold chain transportation can be carried out by road, water, rail, or air, or it can be a combination of multiple transportation methods. Cold chain transportation is an important part of cold chain logistics. Cold chain transportation is costly and involves complex mobile refrigeration technology and insulated box manufacturing technology.

[0003] In existing technologies, most cold boxes in industrial applications typically adopt relatively traditional structural types and connection methods. However, the internal structural design of most cold boxes is not reasonable enough, resulting in unstable temperature control. Furthermore, the fixing methods between pipes and cold boxes are simple, which can easily lead to loosening or detachment, thereby affecting the stability and safety of the overall structure. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a cold box with a novel connection structure to solve the technical problems of most cold boxes having an unreasonable internal structure design, resulting in unstable temperature control, and the simple fixing method between the pipes and the cold box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold box with a novel connection structure, comprising a sleeve body, wherein a fixing ring is fixedly connected to the surface of the sleeve body, and the surface of the fixing ring is threaded, and a locking ring is movably connected to the outside of the fixing ring, the locking ring being composed of a rotating ring, a threaded ring, and a buffer opening, wherein a threaded ring is fixedly connected to one side of the rotating ring, the threaded ring having a thread inside that mates with the fixing ring, and the threaded ring extending outward from thick to thin, and multiple sets of buffer openings being formed inside the threaded ring.

[0006] By adopting the above technical solution, since the threaded ring extends outward from thick to thin, the threaded ring further compresses and fixes the first extrusion block, while the third extrusion block extends outward further, thereby making the pipe further lock and seal with the cold-facing outer wall through the fixing ring. At the same time, the structure with multiple sets of buffer ports inside the threaded ring avoids the problem of excessive compression and cracking of the threaded ring.

[0007] Furthermore, the fixed ring is provided with a compression mechanism, which includes a first compression block, a second compression block and a third compression block that are slidably connected thereto. The first compression block and the second compression block have one end contact surface that is connected at an angle, and the third compression block and the second compression block have the other end contact surface that is connected at an angle.

[0008] By adopting the above technical solution, when the first extrusion block moves into the hole opened in the outer wall of the cold box, the outer wall of the cold box extrudes the first extrusion block, and at the same time the first extrusion block extrudes the second extrusion block, and then the other end of the second extrusion block extrudes the third extrusion block outward.

[0009] Furthermore, both sides of the first extrusion block and the second extrusion block are provided with "T"-shaped blocks that cooperate with the fixing ring, and the fixing ring has a cavity inside that cooperates with the first extrusion block, the second extrusion block and the third extrusion block.

[0010] By adopting the above technical solution, the structure in which "T"-shaped blocks that cooperate with the fixing ring are provided on both sides of the first extrusion block and the second extrusion block, the first extrusion block and the second extrusion block can be limited to move. At the same time, the structure in which the fixing ring has a cavity that cooperates with the first extrusion block, the second extrusion block and the third extrusion block can be slid.

[0011] Furthermore, a pipe is movably connected inside the sleeve body, and a glass fiber cloth is provided at one end of the sleeve body. The sleeve body and the glass fiber cloth are fixedly connected by stainless steel cable ties, and the pipe and the glass fiber cloth are fixedly connected by stainless steel cable ties.

[0012] By adopting the above technical solution, the pipe is fixed to the main body of the cold box through the cold box connection structure. The sleeve body is inserted into the outside of the pipe. After the sleeve is inserted, the pipe and the sleeve body are wrapped with glass fiber cotton cloth and tied with stainless steel cable ties.

[0013] Furthermore, the sleeve body has a filling cavity inside that matches the glass fiber cotton cloth, and the filling cavity is filled with slag cotton.

[0014] By adopting the above technical solution, the sleeve body has a filling cavity that matches the glass fiber cotton cloth, making it easy for users to fill the slag wool into the cavity between the filling cavity and the glass fiber cotton cloth.

[0015] Furthermore, an arc angle that mates with the threaded ring is provided on one side of the top of the first extrusion block, a cold box is provided on the outside of the locking ring, and the pipe is movably connected to the outer frame of the cold box through a fixing ring and a locking ring.

[0016] By adopting the above technical solution, the pipe with the sleeve body installed is inserted into the corresponding hole opened in the outer wall of the cold box. When the fixing ring passes through the outer wall of the cold box, the third extrusion block is hidden inside the fixing ring and passes through the hole opened in the outer wall of the cold box.

[0017] In summary, this utility model has the following beneficial effects: A stainless steel sleeve is inserted into the outside of the pipe, and both ends are wrapped with fiberglass cloth and secured with stainless steel cable ties. The composite plate is then fully welded to the aluminum pipe to ensure a tight external connection. Finally, a fixing plate and fiberglass cloth are added to the outside of the cold box frame to complete the overall assembly. Simultaneously, a fixing ring, a locking ring, and a compression mechanism are used between the pipe and the cold box frame to connect them and improve the sealing effect. Specifically, the locking ring is threaded onto the fixing ring from the outside of the cold box wall. The threaded ring further compresses and fixes the first compression block, while simultaneously extending the third compression block further outwards, thereby further locking and sealing the pipe to the cold box wall through the fixing ring.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A cold box with a novel connection structure, such as Figure 1-10 As shown, the sleeve body 1 includes a fixed ring 2 fixedly connected to the surface of the sleeve body 1, and the fixed ring 2 has threads on its surface. A locking ring 5 is movably connected to the outside of the fixed ring 2. The locking ring 5 consists of a rotating ring 501, a threaded ring 502, and a buffer port 503. The threaded ring 502 is fixedly connected to one side of the rotating ring 501. The threaded ring 502 has threads inside that cooperate with the fixed ring 2, and the threaded ring 502 extends outward from thick to thin. Multiple buffer ports 503 are opened inside the threaded ring 502. During use, because the threaded ring 502 extends outward from thick to thin, the threaded ring 502 further compresses and fixes the first extrusion block 801, and at the same time causes the third extrusion block 803 to extend further outward, so that the pipe 6 is further locked and sealed to the cold outer wall 7 through the fixed ring 2.

[0032] Please see Figure 10 The fixing ring 2 is equipped with a compression mechanism 8. The compression mechanism 8 includes a first compression block 801, a second compression block 802, and a third compression block 803 that are slidably connected thereto. The contact surfaces of the first compression block 801 and the second compression block 802 are connected at one end with an inclined surface, and the contact surfaces of the third compression block 803 and the second compression block 802 are connected at the other end with an inclined surface. When the first compression block 801 moves into the hole opened in the outer wall 7 of the cold box, the outer wall 7 of the cold box compresses the first compression block 801. At the same time, the first compression block 801 compresses the second compression block 802. Then, the other end of the second compression block 802 compresses the third compression block 803 outward, thereby achieving the function of allowing the fixing ring 2 to pass through the outer wall 7 of the cold box.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The sleeve body 1 has a pipe 6 connected inside. One end of the sleeve body 1 is provided with glass fiber cotton cloth 3. The sleeve body 1 and the glass fiber cotton cloth 3 are fixedly connected by stainless steel cable ties 4. The pipe 6 and the glass fiber cotton cloth 3 are also fixedly connected by stainless steel cable ties 4. The user fills the cavity between the filling cavity 9 and the glass fiber cotton cloth 3 with slag cotton. After the sleeve is inserted, the pipe and the sleeve body are wrapped with glass fiber cotton cloth 3 and tied tightly with stainless steel cable ties 4.

[0034] The working principle of this utility model is as follows: When in use, the user first processes the inner and outer surfaces of the cold box body to ensure that its smoothness meets the requirements, makes the cold box cover plate, and welds and fixes the cold box cover plate to the cold box body through argon arc welding process, installs the cold box insulation layer, and fixes it to the cold box body through the cold box connection structure, inserts the sleeve body 1 into the outside of the pipe 6, and at the same time, the user fills the slag wool into the cavity between the filling cavity 9 and the glass wool cloth 3, and finally inserts the two ends with glass wool cloth 3 and ties them tightly with stainless steel cable ties 4;

[0035] During use, the pipe 6 with the sleeve body 1 installed is inserted into the corresponding hole opened in the outer wall 7 of the cold box. When the fixing ring 2 passes through the outer wall 7 of the cold box, the third extrusion block 803 is hidden inside the fixing ring 2 and passes through the hole opened in the outer wall 7 of the cold box. Further, when the first extrusion block 801 moves into the hole opened in the outer wall 7 of the cold box, the outer wall 7 of the cold box extrudes the first extrusion block 801, and at the same time the first extrusion block 801 extrudes the second extrusion block 802. Then the other end of the second extrusion block 802 extrudes the third extrusion block 803 outward.

[0036] Furthermore, the user connects the locking ring 5 to the threaded surface of the fixing ring 2 from the outside of the cold-to-outer wall 7. During the connection process, because the threaded ring 502 extends outward from thick to thin, the threaded ring 502 further compresses and fixes the first extrusion block 801, while the third extrusion block 803 extends outward further, thereby further locking and sealing the pipe 6 to the cold-to-outer wall 7 through the fixing ring 2.

[0037] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
