Technical Field

[0001] This utility model relates to the field of grooved pipe fittings technology, and in particular to a quick-connect grooved pipe fitting. Background Technology

[0002] When existing grooved steel pipe fittings are connected to other pipe fittings, stainless steel pipe fittings are mostly connected by welding. This method is troublesome and time-consuming for workers to disassemble, install, and replace, and the pipe fittings are easily damaged during disassembly.

[0003] In the prior art, patent (CN212986377U) proposes a stainless steel quick-connect grooved pipe fitting, including a pipe fitting body. A pipe is inserted into the left end of the pipe fitting body. An annular sealing groove is formed inside the left end of the pipe fitting body. A retaining ring is fixedly connected inside the annular sealing groove. The retaining ring and rubber sealing ring inside the connector of the pipe fitting body engage the annular groove on the outside of the pipe, so that the pipe is engaged inside the connector of the pipe fitting body. Then, by closing the first arc-shaped clamp and the second arc-shaped clamp with rotating bolts, the arc-shaped rubber sealing strip on the inner side of the arc-shaped clamp squeezes and seals the outside of the pipe and the connector of the pipe fitting body, making the connection between the pipe and the pipe fitting more airtight and preventing the pipe fitting from falling off. This avoids the welding connection method and makes the disassembly, installation and replacement of the pipe more convenient and quick for the workers.

[0004] However, in the aforementioned prior art, the sealing performance of the cannula body is poor after connection, and the squeezing and disassembly after connection can easily cause damage to the cannula. Summary of the Invention

[0005] The purpose of this utility model is to provide a quick-connect grooved pipe fitting, which solves the problems of poor sealing of the pipe fitting body after connection and easy damage to the pipe during squeezing and disassembly after connection in the prior art.

[0006] To achieve the above objectives, this utility model provides a quick-connect grooved pipe fitting, including a grooved main pipe and a plug-in mechanism. The plug-in mechanism includes a bottom ring, a first threaded cylinder, a locking cap, a plug-in pipe, multiple supporting rods, a sealing assembly, and a connecting cylinder. The connecting cylinder is fixedly connected to the plug-in pipe and located on the periphery of the plug-in pipe. The sealing assembly and each of the supporting rods are fixedly connected to the plug-in pipe and located at the inner end of the plug-in pipe. The plug-in pipe is detachably connected to the grooved main pipe and located at one end of the grooved main pipe. The locking cap is threadedly connected to the first threaded cylinder and located on the periphery of the first threaded cylinder. The first threaded cylinder and the bottom ring are both fixedly connected to the grooved main pipe and located on the periphery of the grooved main pipe.

[0007] The insertion tube includes a tube body and an anti-slip sleeve. The anti-slip sleeve is fixedly connected to the tube body and located on the periphery of the tube body. The tube body is detachably connected to the grooved main tube and located at one end of the grooved main tube.

[0008] Each of the supporting rods includes a rod body and a supporting pad. The supporting pad is fixedly connected to the rod body and is located at one end of the rod body. The other end of the rod body is fixedly connected to the pipe body and is located at the end of the pipe body near the main channel of the trench.

[0009] The sealing assembly includes a sealing cylinder and a sealing ring. The sealing ring is fixedly connected to the sealing cylinder and located at one end of the sealing cylinder. The other end of the sealing cylinder is fixedly connected to the pipe body and located at the end of the pipe body near the main groove.

[0010] The connecting cylinder includes a second threaded cylinder and a retaining ring. The retaining ring is fixedly connected to the second threaded cylinder and is located on one side of the second threaded cylinder. The second threaded cylinder is fixedly connected to the pipe body and is located on the periphery of the pipe body.

[0011] This utility model discloses a quick-connect grooved pipe fitting. In the conventional design, the first threaded cylinder and the locking cap are connected by a second threaded cylinder inside the connecting cylinder and locked by the locking cap to prevent further movement between the grooved main pipe and the insertion pipe. The abutment pads at the outer ends of the multiple abutment rods, together with the sealing rings in the sealing assembly, enhance the sealing performance after the pipe connection. This design is convenient to operate and solves the problems of poor sealing performance of the insertion pipe fitting body after connection and easy damage to the insertion pipe caused by squeezing and disassembling after connection.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-5 ,in Figure 1 This is a schematic diagram of the overall structure of a quick-connect grooved pipe fitting according to this utility model.

[0021] This utility model provides a quick-connect grooved pipe fitting, including a grooved main pipe 101 and a plug-in mechanism 102. The plug-in mechanism 102 includes a bottom ring 103, a first threaded cylinder 104, a locking cap 105, a plug-in pipe 106, multiple abutment rods 107, a sealing assembly 108, and a connecting cylinder 109. The plug-in pipe 106 includes a pipe body 110 and an anti-slip sleeve 111. Each abutment rod 107 includes a rod body 112 and an abutment pad 113. The sealing assembly 108 includes a sealing cylinder 114 and a sealing ring 115. The connecting cylinder 109 includes a second threaded cylinder 116 and an abutment ring 117.

[0022] In this specific embodiment, the connecting cylinder 109 is fixedly connected to the insertion pipe 106, the sealing assembly 108 and each of the supporting rods 107 are fixedly connected to the insertion pipe 106, the insertion pipe 106 is detachably connected to the grooved main pipe 101, the locking cap 105 is threadedly connected to the first threaded cylinder 104, the first threaded cylinder 104 and the bottom ring 103 are fixedly connected to the grooved main pipe 101, the anti-slip sleeve 111 is fixedly connected to the pipe body 110, the pipe body 110 is detachably connected to the grooved main pipe 101, the supporting pad 113 is fixedly connected to the rod body 112, the other end of the rod body 112 is fixedly connected to the pipe body 110, the sealing ring 115 is fixedly connected to the sealing cylinder 114, and the sealing cylinder 11... The other end of 4 is fixedly connected to the pipe body 110. The abutment ring 117 is fixedly connected to the second threaded cylinder 116. The second threaded cylinder 116 is fixedly connected to the pipe body 110. The existing first threaded cylinder 104 and the locking cap 105 are threadedly connected through the second threaded cylinder 116 in the connecting cylinder 109 and locked by the locking cap 105 to prevent the grooved main pipe 101 and the insertion pipe 106 from moving again. The abutment pads 113 at the outer ends of the multiple abutment rods 107 cooperate with the sealing rings 115 in the sealing assembly 108 to enhance the sealing performance after the pipe is connected. This design is convenient to operate and solves the problem that the sealing performance of the insertion pipe body is poor after connection and that the compression and disassembly after connection can easily cause damage to the insertion pipe.

[0023] The connecting cylinder 109 is located around the insertion tube 106. The sealing assembly 108 and each of the supporting rods 107 are located at the inner end of the insertion tube 106. The insertion tube 106 is located at one end of the grooved main tube 101. The locking cap 105 is located around the first threaded cylinder 104. The first threaded cylinder 104 and the bottom ring 103 are both located around the grooved main tube 101. The outer sides of the first threaded cylinder 104 and the second threaded cylinder 116 have continuous threads. After the operator inserts the tube body 110, the locking cap 105 can be directly rotated and connected by threads. Due to the setting of the supporting ring 117, when the operator rotates the locking cap 105 to the side of the supporting ring 117, the locking cap 105 is just positioned between the first threaded cylinder 104 and the second threaded cylinder 116, ensuring the stability of the connection.

[0024] Secondly, the anti-slip sleeve 111 is located on the periphery of the pipe body 110, the pipe body 110 is located at one end of the grooved main pipe 101, the abutment pad 113 is located at one end of the rod body 112, and the other end of the rod body 112 is located at the end of the pipe body 110 near the grooved main pipe 101. The anti-slip sleeve 111 is designed to allow workers to better grip the periphery of the pipe body 110. Each rod body 112 at the inner end of the pipe body 110 is inserted into the inner side of the grooved main pipe 101. After the initial connection is completed, the locking cap 105 is rotated to achieve a tight fit. Each abutment pad 113 and the sealing ring 115 deforms after fitting with the inner side of the grooved main pipe 101, thereby filling the gap at the connection and ensuring the sealing of the pipe connection.

[0025] Meanwhile, the sealing ring 115 is located at one end of the sealing cylinder 114, and the other end of the sealing cylinder 114 is located at the end of the pipe body 110 near the grooved main pipe 101. The abutment ring 117 is located on one side of the second threaded cylinder 116, which is located on the periphery of the pipe body 110. When connecting the pipes, each rod 112 on the pipe body 110 is first inserted into the grooved main pipe 101 at the end with the slot. After the insertion is stable, the abutment pad 11 at the inner end of each rod 112... The sealing rings 115 at the inner end of the sealing cylinder 114 and the sealing cylinder 114 are tightly fitted to the grooved main pipe 101. When the operator rotates the locking cap 105, since the inner wall of the locking cap 105 has threads that are compatible with the outer sides of the first threaded cylinder 104 and the second threaded cylinder 116, the pipe body 110 and the grooved main pipe 101 are locked together by the locking cap 105 after being fitted and installed. The operator can complete the connection between the pipe body 110 and the grooved main pipe 101 by only two actions: insertion and rotation, which is quick and simple.

[0026] In this embodiment, the outer sides of the first threaded cylinder 104 and the second threaded cylinder 116 have continuous threads. After the operator inserts the tube body 110, the locking cap 105 can be directly connected by threaded rotation. Due to the setting of the abutment ring 117, when the operator rotates the locking cap 105 to the side of the abutment ring 117, the locking cap 105 is positioned between the first threaded cylinder 104 and the second threaded cylinder 116, ensuring a stable connection. The anti-slip sleeve 111 allows the operator to better grip the circumference of the tube body 110. After inserting each rod 112 at the inner end of the tube body 110 into the inner side of the grooved main pipe 101 and completing the initial connection, the locking cap 105 is rotated to achieve a tight fit. Each abutment pad 113 and the sealing ring 115 are located on the inner side of the grooved main pipe 101. After fitting, deformation occurs, filling the gap at the joint and ensuring the sealing of the pipe connection. During pipe connection, each rod 112 on the pipe body 110 is first inserted into the slotted end of the grooved main pipe 101. After stable insertion, the retaining pad 113 at the inner end of each rod 112 and the sealing ring 115 at the inner end of the sealing cylinder 114 are tightly fitted to the grooved main pipe 101. The operator rotates the locking cap 105. Since the inner wall of the locking cap 105 has threads that match the outer sides of the first threaded cylinder 104 and the second threaded cylinder 116, the pipe body 110 and the grooved main pipe 101 are locked together after fitting. The operator completes the connection of the pipe body 110 and the grooved main pipe 101 quickly and easily by simply inserting and rotating the rod.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
