Description

Technical Field

[0001] The utility model relates to the field of pipe fittings, in particular to a new type of pipe fitting which is easy to disassemble and assemble. Background Art

[0002] Pipe fittings are a general term for components in pipeline systems that perform functions such as connection, control, direction change, flow diversion, sealing, and support.

[0003] Currently, most of the connections between pipe fittings are made by threaded connection. However, threaded connection requires the use of matching tools to tighten, and the connection is time-consuming and laborious, especially in corners where tools are difficult to penetrate. Connecting pipe fittings is extremely time-consuming and laborious. Therefore, it is necessary to design a disassembly and assembly structure to improve the simplicity and timeliness of pipe connection. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a new type of pipe fitting that is easy to disassemble and assemble, so as to solve the technical problem that threaded connection between pipe fittings is time-consuming and labor-intensive.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of pipe fitting that is easy to disassemble and assemble, comprising a pipe fitting main body,

[0006] The first connecting end comprises an expansion tube, a pressing piece is movably provided on the inner wall of the expansion tube, an arc-shaped inclined surface is provided on the outer side of one end of the pressing piece, a protrusion is provided on the outer side of the pressing piece close to the arc-shaped inclined surface, and a plurality of spring pieces are fixed in the middle of the inner wall of the expansion tube.

[0007] By adopting the above technical solution, users can connect and disassemble pipe fittings by simply pressing the parts, without using complicated tools or performing cumbersome steps, making the operation easy and convenient. The curved slope can make the spring piece more inclined, making it easier to disassemble the pipe fittings.

[0008] Furthermore, the pressing member is an annular tubular structure, and the other end of the pressing member is connected to a paddle, and the outer diameter of the paddle is the same as the outer diameter of the expansion tube.

[0009] By adopting the above technical solution, the annular tubular structure makes the pressing piece stronger and less prone to damage. The close fit between the pressing piece and the expansion tube also enhances the structural stability of the entire connecting end, effectively preventing the pipe from loosening or falling off during the connection process.

[0010] Furthermore, two sealing rings are provided on the other side of the inner wall of the expansion tube, and the two sealing rings are arranged parallel to each other. A clamping end for limiting is provided on the side of the inner wall of the expansion tube away from the sealing ring.

[0011] By adopting the above technical solution, the double sealing design significantly improves the sealing performance of the pipe fittings. The two sealing rings can work together to ensure a tight connection between the connection ends and effectively prevent fluid leakage.

[0012] Furthermore, the shrapnel is a metal shrapnel, and a plurality of the metal shrapnel are provided. The plurality of the metal shrapnel are annularly arranged on the inner wall of the expansion tube, and the plurality of metal shrapnel form an annular metal ring.

[0013] By adopting the above technical solution, the spring piece is made of metal material, such as stainless steel, which has excellent elasticity and recovery. After being subjected to external force, the spring piece can quickly return to its original shape and maintain lasting elasticity, thereby ensuring a tight connection of the pipe fittings.

[0014] Furthermore, the spring piece is inclined along the direction of the sealing ring, and the end of the spring piece is sharp.

[0015] By adopting the above technical solution, the sharp end increases the friction between the spring piece and the outer wall of the second connecting end, thereby making the connection more stable and ensuring the stability and sealing of the pipe connection.

[0016] Furthermore, the pressing member slides on the inner wall of the expansion tube, and the arc-shaped inclined surface is used to squeeze the spring sheet.

[0017] Furthermore, one end of the pipe body is a first connection end, and the other end of the pipe body is a second connection end.

[0018] By adopting the above technical solution, the user operates the pipe fitting by simply pushing or pressing. The arc-shaped inclined surface squeezes the spring sheet during the sliding process, causing the spring sheet to deform when subjected to pressure, thereby achieving rapid connection and disassembly of the pipe fitting. This sliding and squeezing mechanism not only simplifies the operation process, but also improves the connection efficiency. The first connection end and the second connection end adopt a plug-in connection method, which is simple, fast and reliable.

[0019] Furthermore, the first connection end is plugged into the second connection end.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model sets a first connection end at one end of the pipe fitting, and the first connection end is a quick disassembly mechanism, including an expansion tube and a pressing piece. The spring piece and the pressing piece built into the expansion tube realize a quick and easy connection and disassembly process. The user does not need to use complicated tools or perform cumbersome steps, but only needs to push or pull the pressing piece to complete the connection or disassembly of the pipe fitting, which greatly saves time and labor and improves work efficiency.

[0022] 2. The utility model provides sealing rings at the connecting ends of the pipes, which can fit tightly against the outer wall of another pipe during connection, thereby effectively preventing liquid or gas leakage. This design ensures the sealing of the pipeline system and ensures the safe transmission of the fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1:

[0031] A new type of pipe fitting that is easy to disassemble and assemble, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes a pipe fitting body 1,

[0032] The first connecting end 2 includes an expansion tube 21, and a pressing piece 24 is movably provided on the inner wall of the expansion tube 21. An arc-shaped inclined surface 241 is provided on the outer side of one end of the pressing piece 24. A protrusion is provided on the outer side of the pressing piece 24 close to the arc-shaped inclined surface 241. A plurality of spring pieces 23 are fixed in the middle of the inner wall of the expansion tube 21. The user only needs to press the pressing piece 24 to connect and disassemble the pipe fitting without using complicated tools or performing cumbersome steps, making the operation easy and convenient. The arc-shaped inclined surface 241 can make the spring piece more inclined, which is convenient for disassembly of the pipe fitting. The protrusion can be clamped with the clamping end 211 on the expansion tube 21 to prevent the pressing piece 24 from falling off and limit the range of movement of the pressing piece 24.

[0033] See also Figure 3 , Figure 4 The pressing piece 24 is an annular tubular structure, and a paddle 25 is connected to the other end of the pressing piece 24. The outer diameter of the paddle 25 is the same as the outer diameter of the expansion tube 21. The annular tubular structure makes the pressing piece 24 stronger and less prone to damage. The close fit between the pressing piece 24 and the expansion tube 21 also enhances the structural stability of the entire connecting end, effectively preventing the pipe from loosening or falling off during the connection process. The outer diameter of the paddle 25 is the same as the outer diameter of the expansion tube 21, which means that the user can easily operate the pressing piece 24 by pressing the paddle 25.

[0034] See also Figure 3 Two sealing rings 22 are provided on the other side of the inner wall of the expansion pipe 21. The two sealing rings 22 are arranged parallel to each other. The double sealing design significantly improves the sealing performance of the pipe fitting. The two sealing rings can work together to ensure a tight connection between the connection ends and effectively prevent fluid leakage. By enhancing the sealing performance and connection reliability, it helps to improve the performance of the entire pipeline system, ensure that the fluid maintains a constant pressure and flow during the transmission process, and reduce the risk of leakage.

[0035] Embodiment 2:

[0036] See also Figure 3 , Figure 4 The shrapnel 23 is a metal shrapnel, and there are several metal shrapnels, which are arranged in a ring shape on the inner wall of the expansion tube 21, and the several metal shrapnels form an annular metal ring. The shrapnel 23 is made of metal material, such as stainless steel, and has excellent elasticity and recovery. After being subjected to external force, the shrapnel can quickly return to its original shape and maintain lasting elasticity, thereby ensuring the tight connection of the pipe fittings. Several metal shrapnels are arranged in a ring shape on the inner wall of the expansion tube 21 to form an annular metal ring, which ensures that the shrapnel can evenly distribute the support and connection force when it conflicts, preventing the pipe fittings from deformation or stress concentration during the connection process, thereby improving the stability and safety of the connection.

[0037] See also Figure 3, Figure 4 The spring piece 23 is inclined along the direction of the sealing ring 22, and the end of the spring piece 23 is sharp. The sharp end increases the friction between the spring piece 23 and the outer wall of the second connecting end 3, thereby making the connection more stable and ensuring the stability and sealing of the pipe connection.

[0038] See also Figure 3 , Figure 4 The pressing piece 24 slides on the inner wall of the expansion tube 21, and the arc-shaped inclined surface 241 is used to squeeze the spring piece 23. One end of the pipe body 1 is the first connection end 2, and the other end of the pipe body 1 is the second connection end 3. The user operates the pipe by simply pushing or pressing. The arc-shaped inclined surface 241 squeezes the spring piece 23 during the sliding process, so that the spring piece is deformed when it is under pressure, thereby realizing the rapid connection and disassembly of the pipe. This sliding and squeezing mechanism not only simplifies the operation process, but also improves the connection efficiency. The first connection end 2 and the second connection end 3 adopt a plug-in connection method. This connection method is simple, fast and reliable. The plug-in connection does not require complicated tools or steps. You only need to align and insert the two connection ends, which greatly saves installation time and cost.

[0039] The implementation principle of the utility model is as follows: first, take out two pipes to be connected, and bring the first connection end 2 of one pipe body 1 and the second connection end 3 of the other pipe body 1 close to each other, and insert the second connection end 3 into the pressing piece 24 until it cannot be inserted. When the second connection end 3 is inserted, the second connection end 3 moves inward and gradually squeezes the spring sheet 23, so that the spring sheet 23 is more inclined along the direction of the sealing ring 22 until the second connection end 3 is inserted into the sealing ring 22. At this time, the middle position of the metal ring composed of a plurality of spring sheets 23 contacts the second connection end 3 to maintain the connection stability of the first connection end 2 and the second connection end 3. When the second connection end 3 is separated from the first connection end 2, the second connection end 3 pulls the spring sheet 23, and one end of the inclined spring sheet 23 contacts the second connection end 3, and the other end contacts the inner wall of the expansion tube 21 on the first connection end 2. Therefore, the more the second connection end 3 is separated, the tighter the connection is.

[0040] When the two pipe bodies 1 need to be disassembled, it is only necessary to press the paddle 25, and the paddle 25 squeezes the pressing member 24, so that the arc-shaped inclined surface 241 inside the pressing member 24 squeezes the spring piece 23, and the spring piece 23 is tilted, so that the end of the spring piece 23 is separated from the second connecting end 3. At this time, the second connecting end 3 can be pulled out with a light pull. The operation is simple, and the disassembly and assembly only takes a few seconds, which is time-efficient.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
