Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, specifically a pipe connection structure. Background Technology
[0002] Pipe connection structures are an important component of pipeline engineering. Their selection and application directly affect the safety and reliability of the entire system. Depending on different needs and pipe materials, there are various pipe connection methods, each with its own characteristics and applicable scope. Among them, building HVAC pipelines include heating, ventilation, and air conditioning. These three aspects are collectively referred to as HVAC. The heating system consists of three main parts: heat medium preparation (heat source), heat medium transportation, and heat medium utilization (heat dissipation equipment). Ventilation improves the indoor air environment through ventilation and air exchange. Air conditioning aims to create an air environment that meets the needs of human production, life, and scientific experiments.
[0003] Most existing pipe connection structures use traditional tightening methods, which have many shortcomings in actual operation. First, traditional threaded connections require multiple tightenings with tools, which is not only time-consuming and labor-intensive, but also prone to stripping or jamming, further increasing the assembly difficulty. In addition, when there are many pipe connection points or the installation space is narrow, the operation difficulty will increase significantly, resulting in a significant reduction in overall assembly efficiency. Therefore, how to design a pipe connection structure that can quickly and stably complete the connection and significantly improve installation and maintenance efficiency has become an urgent problem to be solved. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a pipe connection structure to solve the technical problem that traditional threaded connections require multiple tightenings with the help of tools, which is not only time-consuming and laborious, but also prone to stripping or jamming, further increasing the difficulty of assembly.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipe connection structure, comprising a first pipe and a second pipe, wherein a first positioning sleeve is fixedly connected to the surface of the first pipe, the first positioning sleeve comprising a first thread, a second thread, a convex ring and a through groove, and a second positioning sleeve is fixedly connected to the surface of the second pipe, the second positioning sleeve comprising a third thread.
[0006] By adopting the above technical solution, concave rings are formed on the outer surfaces of the first and second pipes, and convex rings that match the concave rings are set on the inner walls of the first and second positioning sleeves. Thus, the inner diameters of the first and second positioning sleeves can be equal to the outer diameters of the first and second pipes. During the process of fitting the first and second positioning sleeves onto the surfaces of the first and second pipes respectively, the through grooves allow the first and second positioning sleeves to open. When the convex ring reaches the concave ring, the first and second positioning sleeves close. Installation is simple. After the convex ring is engaged in the concave ring, the first and second positioning sleeves return to their original shape. Therefore, it is also very labor-saving to connect the positioning bolts to the first and second positioning sleeves, achieving the purpose of saving time and effort and speeding up the assembly efficiency. The fastening structure between the first and second positioning sleeves and the first and second pipes is the convex ring and the concave ring. After the convex ring is engaged in the concave ring, the first and second positioning sleeves can be engaged with the outer surfaces of the first and second pipes respectively. This connection method is not only firm, but also relatively simple to produce, reducing manufacturing costs.
[0007] Furthermore, a first thread is provided on one side surface of the first positioning sleeve, a second thread is provided on the other side surface of the first positioning sleeve, a convex ring is provided on the inner side of the first positioning sleeve, and multiple sets of through grooves are provided on the surface of the first positioning sleeve.
[0008] By adopting the above technical solution, the multiple sets of threads achieve the effect of fixing the bolts.
[0009] Furthermore, a third thread is provided on one side of the surface of the second positioning sleeve, a convex ring is provided on the inner side of the second positioning sleeve, and multiple sets of through grooves are provided on the surface of the second positioning sleeve.
[0010] By adopting the above technical solution, the first positioning sleeve and the second positioning sleeve are opened by the through groove, and when the convex ring reaches the concave ring, the first positioning sleeve and the second positioning sleeve are closed.
[0011] Furthermore, the surface of the first pipe is provided with a concave ring that mates with the convex ring, and the surface of the first positioning sleeve is threaded with a positioning bolt.
[0012] By adopting the above technical solution, the convex ring serves as a fixed positioning sleeve.
[0013] Furthermore, the first positioning sleeve is threaded with a first bolt, and the second positioning sleeve is threaded with a second bolt.
[0014] By adopting the above technical solution, the two sets of bolts effectively fix the positioning sleeve.
[0015] Furthermore, a sealing ring is provided between the first pipe and the second pipe, and a traction ring is fixedly connected to one side of the positioning bolt.
[0016] By adopting the above technical solution, the traction ring was designed to bring the second pipe closer to the first pipe.
[0017] In summary, this utility model has the following advantages: By creating concave rings on the outer surfaces of the first and second pipes, and providing convex rings that match the concave rings on the inner walls of the first and second positioning sleeves, the inner diameters of the first and second positioning sleeves can be equal to the outer diameters of the first and second pipes. During the process of fitting the first and second positioning sleeves onto the surfaces of the first and second pipes respectively, the through grooves allow the first and second positioning sleeves to open. When the convex ring reaches the concave ring, the first and second positioning sleeves close, simplifying installation. After the convex ring engages with the concave ring, the first and second positioning sleeves return to their original shape, thus saving effort when connecting the positioning bolts. This achieves the goal of saving time and effort, and speeds up assembly efficiency. The fastening structure between the first and second positioning sleeves and the first and second pipes is a convex ring and a concave ring. After the convex ring engages with the concave ring, the first and second positioning sleeves can respectively mesh with the outer surfaces of the first and second pipes. This connection method is not only strong but also relatively simple to produce, reducing manufacturing costs. Attached Figure Description

[0024] 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.
[0025] The embodiments of this utility model will be described below based on its overall structure.
[0026] A pipe connection structure, such as Figure 1-5 As shown, the system includes a first pipe 1 and a second pipe. A first positioning sleeve 3 is fixedly connected to the surface of the first pipe 1. The first positioning sleeve 3 includes a first thread 301, a second thread 302, a convex ring 303, and a through groove 304. A second positioning sleeve 4 is fixedly connected to the surface of the second pipe 2. The second positioning sleeve 4 includes a third thread 401. The first positioning sleeve 3 has a first thread 301 on one side and a second thread 302 on the other side. A convex ring 303 is provided inside the first positioning sleeve 3. Multiple sets of through grooves 304 are provided on the surface of the first positioning sleeve 3. The second positioning sleeve 4 has a third thread 401 on one side and a convex ring is provided inside the second positioning sleeve. 303. The surface of the second positioning sleeve 4 has multiple sets of through grooves 304. Specifically, the first pipe 1 and the second pipe 2 are prepared, and the first bolt 7 and the second bolt 8 are respectively installed on the pipe surface. Then, the first positioning sleeve 3 is installed on the outer surface of the first pipe 1, so that the convex ring 303 on the inner wall of the first positioning sleeve 3 is engaged in the concave ring 5 of the first pipe 1. Through the action of the through grooves 304, the positioning sleeve can open and return to its original shape after the convex ring 303 is engaged in the concave ring 5, tightly meshing with the surface of the first pipe 1. Similarly, the second positioning sleeve 4 is installed on the outer surface of the second pipe 2, so that the convex ring 303 is engaged in the concave ring 5 of the second pipe 2, thus completing the fixation of the second pipe 2.
[0027] Please see Figure 1 , Figure 4 and Figure 5 The surface of the first pipe 1 is provided with a concave ring 5 that mates with the convex ring 303. The surface of the first positioning sleeve 3 is threaded with a positioning bolt 6 and a first bolt 7. The surface of the second positioning sleeve 4 is threaded with a second bolt 8. A sealing ring 9 is provided between the first pipe 1 and the second pipe 2. A traction ring 10 is fixedly connected to one side of the positioning bolt 6. Specifically, when the two pipes are connected, the sealing ring 9 is placed between the first pipe 1 and the second pipe 2, so that one side of the sealing ring 9 overlaps with the end of the first pipe 1 and the other side contacts the end of the second pipe 2. By moving the first bolt 7 and the second bolt 8, it is slid to the outer surface of the first positioning sleeve 3 and the second positioning sleeve 4, and threadedly connected to the first thread 301 and the second thread 302 respectively, thus initially fixing the relative position of the two positioning sleeves.
[0028] Next, install the positioning bolt 6, pass the positioning bolt 6 through the traction ring 10, and thread it onto the first thread 301 of the first positioning sleeve 3 and the second positioning sleeve 4. Rotate the positioning bolt 6, and use the traction ring 10 to gradually bring the second pipe 2 closer to the first pipe 1 until the end of the second pipe 2 is tightly pressed against the sealing ring 9 to form a firm and sealed connection.
[0029] The working principle of this utility model is as follows: When in use, prepare the first pipe 1 and the second pipe 2, and respectively install the first bolt 7 and the second bolt 8 on the pipe surface. Then, install the first positioning sleeve 3 on the outer surface of the first pipe 1, so that the convex ring 303 on the inner wall of the first positioning sleeve 3 is inserted into the concave ring 5 of the first pipe 1. Through the action of the through groove 304, the positioning sleeve can open and return to its original shape after the convex ring 303 is inserted into the concave ring 5, tightly engaging with the surface of the first pipe 1. Similarly, install the second positioning sleeve 4 on the outer surface of the second pipe 2, so that the convex ring 303 is inserted into the concave ring 5 of the second pipe 2, thus completing the fixation of the second pipe 2.
[0030] When the two pipes are connected, the sealing ring 9 is placed between the first pipe 1 and the second pipe 2, so that one side of the sealing ring 9 overlaps with the end of the first pipe 1 and the other side contacts the end of the second pipe 2. By moving the first bolt 7 and the second bolt 8, it is slid to the outer surface of the first positioning sleeve 3 and the second positioning sleeve 4, and threadedly connected to the first thread 301 and the second thread 302 respectively, thus initially fixing the relative position of the two positioning sleeves.
[0031] Next, install the positioning bolt 6, pass the positioning bolt 6 through the traction ring 10, and thread it onto the first thread 301 of the first positioning sleeve 3 and the second positioning sleeve 4. Rotate the positioning bolt 6, and use the traction ring 10 to gradually bring the second pipe 2 closer to the first pipe 1 until the end of the second pipe 2 is tightly pressed against the sealing ring 9 to form a firm and sealed connection.
[0032] This design achieves rapid engagement through the engagement of the convex ring 303 of the first positioning sleeve 3 and the second positioning sleeve 4 with the concave ring 5 on the pipe surface. At the same time, the positioning sleeve is fixed and adjusted by the sliding of the bolts and the threaded connection, which greatly improves the installation efficiency of the pipe connection. The sealing performance of the pipe interface is ensured by the setting of the sealing ring 9, which meets the safety and reliability requirements of industrial pipe connection.
