Description

Technical Field

[0001] This utility model relates to the field of pipe connector technology, and in particular to a pipe connector with good sealing effect. Background Technology

[0002] Currently, pipe connectors are devices made of stainless steel and rubber components that achieve sealing and pressure bearing functions. They are very compact in structure and do not require any treatment of the pipe ends during construction, allowing for the connection of pipes for use.

[0003] However, when using connectors to connect pipes, multiple sets of bolts are often inserted sequentially through the outer flange of the pipe and tightened with nuts to connect the pipe and connector. During this process, the operator cannot simultaneously insert a large number of bolts into the flange, resulting in bolts of varying lengths. This leads to inconsistent tightening force applied to different locations on the outer side of the pipe, potentially causing gaps at the pipe connection and affecting the sealing performance of the pipe connector. Therefore, we propose a pipe connector with superior sealing performance. Utility Model Content

[0004] The main objective of this invention is to provide a pipe connector with good sealing performance, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipe connector with good sealing effect includes a connecting pipe rotating sleeve, a pipe body is detachably installed at both ends of the side of the connecting pipe, a first connecting plate is fixedly installed at both ends of the side of the connecting pipe, a second connecting plate is fixedly installed at the top of the side of each pipe body, and a plug hole is opened on the outer side of each first connecting plate and the second connecting plate.

[0007] A bidirectional pushing mechanism is provided on the outer side of the connecting pipe, and a synchronous rotating mechanism is provided on the outer side of the connecting pipe, and the synchronous rotating mechanism and the bidirectional pushing mechanism are connected in a transmission manner.

[0008] As an optional solution to the technical solution of this application, the bidirectional pushing mechanism includes a bidirectional lead screw, and connecting plates are fixedly installed on both sides of the connecting pipe. The number of connecting plates is several sets. A bidirectional lead screw is rotatably installed on the middle of the side of every two sets of connecting plates through bearings. A movable sleeve is threadedly connected to both sides of the outer side of each bidirectional lead screw. A fixed plate is fixedly installed on both sides of the outer side of each movable sleeve. A connecting screw is fixedly installed on the middle of the side of each fixed rod.

[0009] As an optional solution to the technical solution of this application, the synchronous rotation mechanism includes a transmission gear ring and a transmission gear. The transmission gear ring is fixedly installed on the inner side wall of the rotating sleeve. A transmission gear is fixedly sleeved on the outer middle end of each of the bidirectional lead screws, and the outer side of the transmission gear and the inner side of the transmission gear ring mesh with each other.

[0010] By adopting the above technical solution, the rotating sleeve can be turned by the meshing transmission action of the transmission gear and the transmission gear ring, which can drive multiple sets of bidirectional lead screws to rotate synchronously, thereby enabling multiple sets of connecting screws to move horizontally on the outside of the connecting pipe synchronously.

[0011] As an optional solution to the technical solution of this application, both outer sides of the rotating sleeve are screwed with abutting bolts through threads, and the top edge of the abutting bolt is movably attached to the outer wall of the connecting pipe.

[0012] By adopting the above technical solution, the rotational force of the rotating sleeve can be tightened and limited by the tightening action of the bolt, thereby fixing the position of the connecting screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This application provides a pipe connector with good sealing performance. Multiple sets of bidirectional screws are installed on the outside of the connecting pipe, and a rotating sleeve is rotatably fitted onto the outside of the connecting pipe. After the pipe body side is fitted to both ends of the connecting pipe side, the rotating sleeve can be turned, causing it to rotate outside the connecting pipe. Simultaneously, this rotates the transmission gear ring outside the connecting pipe. The meshing transmission of the transmission gear ring and transmission gears drives multiple sets of transmission gears to rotate synchronously, which in turn drives multiple sets of bidirectional screws to rotate synchronously on the outer wall of the connecting pipe. During the rotation of the bidirectional screws, the movable sleeves fitted on their surfaces move horizontally synchronously. This allows the movable sleeves to move horizontally towards or relative to each other outside the connecting pipe, enabling multiple sets of connecting screws to move horizontally towards or relative to each other synchronously outside the connecting pipe. During this horizontal movement, the connecting screws are simultaneously inserted into the connecting disc, ensuring that the fixed length of the connecting screws inserted into the connecting disc is the same, thus guaranteeing the connection stability of the connecting screws from different positions on the outside of the connecting pipe and the pipe body.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a pipe connector with good sealing effect, wherein pipe bodies 11 are detachably installed at both ends of the side of the connecting pipe 1, and first connecting discs 12 are fixedly installed at both ends of the side of the connecting pipe 1, and second connecting discs 13 are fixedly installed at the top of the side of each pipe body 11. Each first connecting disc 12 and second connecting disc 13 has a plug hole 14 on its outer side, and the connecting screw 27 is slidably inserted into the plug hole 14 through its side.

[0020] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), both sides of the rotating sleeve 2 are threadedly connected with abutment bolts 3, and the top edge of the abutment bolt 3 is movably attached to the outer wall of the connecting pipe 1.

[0021] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a transmission gear ring 24 is fixedly installed on the inner side wall of the rotating sleeve 2. A transmission gear 23 is fixedly sleeved on the middle of the outer side of each bidirectional screw 22, and the outer side of the transmission gear 23 meshes with the inner side of the transmission gear ring 24.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), connecting plates 21 are fixedly installed on both sides of the connecting pipe 1, and there are several sets of connecting plates 21. A double-acting screw 22 is rotatably installed on the middle side of each pair of connecting plates 21 through a bearing. A movable sleeve 25 is threadedly connected to both sides of each double-acting screw 22. A fixing plate 26 is fixedly installed on both sides of each movable sleeve 25. A connecting screw 27 is fixedly installed on the middle side of each fixing rod.

[0023] During operation, after the sides of the two sets of pipe bodies 11 are attached to the outer wall of the connecting pipe 1, so that the first connecting plate 12 can be attached to the outer side of the second connecting plate 13, the tightening bolt 3 is then tightened to remove it from the outside of the connecting pipe 1. The rotating sleeve 2 is then pushed, allowing it to rotate on the outer wall of the connecting pipe 1. This rotation drives the transmission gear ring 24 to rotate outside the connecting pipe 1. Simultaneously, the meshing transmission action of the transmission gear ring 24 and the transmission gear 23 drives the transmission gear 23 and the double-acting screw 22 to rotate synchronously. Combined with the rotational transmission action of the double-acting screw 22 on the movable sleeve 25, the sleeve... The movable sleeves 25 connected to the two sides of the bidirectional lead screw 22 can move synchronously relative to each other, thereby driving the connecting screw 27 to move horizontally on the outside of the connecting pipe 1. This allows multiple sets of connecting screws 27 to pass through the first connecting plate 12 and be inserted into the insertion hole 14 inside the second connecting plate 13. This ensures that the lengths of the multiple sets of connecting screws 27 passing through the first connecting plate 12 and the second connecting plate 13 are the same. Then, nuts are used to tighten them to fully fit the outer wall of the second connecting plate 13, providing the same connection force at different positions on the surfaces of the first connecting plate 12 and the second connecting plate 13, ensuring the connection and sealing between the connecting pipe 1 and the side end of the pipe body 11.
