Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically, to a connector for pipe connection. Background Technology
[0002] Pipe fittings are connecting components used to connect multiple pipes. In the existing technology, when multiple pipes are connected by existing pipe fittings, the connection point of the multiple pipes has the disadvantage of low connection strength, which results in poor resistance to external forces. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a connector for pipe connection, which can improve the connection strength between the pipe and the connector body at both ends of the inner liner pipe, thereby improving the resistance to external forces and the strength of the connection between the pipe and the connector body.
[0004] This utility model provides a connector for connecting pipes, including a connector body for connecting four pipes evenly distributed in a circumferential direction. The connector body is provided with slots corresponding to the four pipes one by one. One end of each of the four pipes is inserted into one of the slots and fastened to the connector body. The connector also includes an inner liner tube. Two slots arranged opposite each other are connected to each other through a connecting channel located inside the connector body. The inner liner tube passes through the connecting channel and its two ends are respectively inserted into the ends of two pipes at corresponding positions. The outer side wall of the end of the inner liner tube is in contact with the inner side wall of the end of the pipe. The inner liner tube is fastened to the pipes and the connector body.
[0005] By adopting the above-mentioned structure, this utility model, under the action of the inner liner, can play a role in assisting to strengthen the structural strength of the connector body and can improve the connection strength between the pipe and the connector body at both ends of the inner liner, thereby improving the effect and strength of the connection between the pipe and the connector body against external forces.
[0006] In one possible implementation, the outer wall of the inner liner is in contact with the inner wall of the connecting channel. With this structure, after the inner liner is inserted into the connecting channel, radial restraint of the inner liner can be achieved to prevent radial displacement of the inner liner, thereby improving the stability of the inner liner and the connector body after assembly. Preferably, the outer wall of the inner liner is tightly fitted with the inner wall of the connecting channel, thereby further restricting the radial displacement of the inner liner and restricting the axial position of the inner liner after it is inserted into the connecting channel. Thus, when the end of the inner liner is inserted into the end of the pipe, axial displacement of the inner liner can be avoided.
[0007] In one possible implementation, the tube is a round tube, and the shape of the slot is adapted to the shape of the tube.
[0008] In one possible implementation, the tubing is a square tube, and the shape of the slot is adapted to the shape of the tubing.
[0009] In one possible implementation, the end of each tube is fastened to the connector body by a screw, which passes through the connector body located on one side of the slot and through the side wall of the tube, and the screw is threaded to both the connector body and the tube; with this structure, the end of each tube can be reliably fastened to the connector body by the screw at the corresponding position.
[0010] In one possible implementation, the two ends of the inner liner tube are fastened to the tube and connector body by screws at corresponding positions; with this structure, both ends of the inner liner tube can be fastened together with the tube and connector body by screws at corresponding positions.
[0011] In one possible implementation, an annular guide surface is provided on the inner wall of the outer end of each slot. The annular guide surface is used to guide the end of the pipe so that the end of the pipe can be inserted into the slot. With this structure, when the end of the pipe is inserted into the slot, the annular guide surface can guide the end of the pipe so that the end of the pipe can be inserted into the slot, which can facilitate the insertion of the end of the pipe into the slot.
[0012] In one possible implementation, the inner liner is a steel pipe; by using a steel pipe to make the inner liner, it has the advantages of high bending strength and high deformation strength.
[0013] In one possible implementation, the pipe is a metal-coated plastic pipe; by using a metal-coated plastic pipe as the pipe material, it has the advantages of high pipe strength and high rigidity, that is, it can withstand a large weight and external force, and can effectively prevent the pipe from rusting. In addition, there is no need to spray or electroplat the pipe material, which has the advantage of being environmentally friendly. Furthermore, in this application, the pipe material used is a plastic-coated steel pipe.
[0014] In one possible implementation, a limiting structure is provided on the inner wall of the connector body located outside the connecting channel. The two ends of the limiting structure are respectively used to abut against the ends of the pipes on the corresponding sides. With this structure, after the ends of the pipes are inserted into the slots located at both ends of the connecting channel, the ends of the pipes can abut against the limiting structure, thereby limiting the pipes and connector bodies. This facilitates the assembly of the pipes and connector bodies and improves the reliability and stability of the assembled pipes and connector bodies.
[0015] In one possible implementation, the limiting structure includes a plurality of limiting blocks arranged circumferentially at intervals on the inner wall of the connector body. With this structure, after the end of the pipe is inserted into the slots located at both ends of the connecting channel, the end of the pipe can abut against the plurality of limiting blocks, thereby limiting the pipe and the connector body. This facilitates the assembly of the pipe and the connector body and improves the reliability and stability of the assembled pipe and connector body. Attached Figure Description

[0030] Implementation Method 1
[0031] See Figure 1-5 As shown in the embodiment of this application, a connector for connecting pipes is disclosed, including a connector body 2 for connecting four pipes 1 evenly distributed in the circumferential direction. The connector body 2 is provided with slots 21 corresponding to the four pipes 1 one by one. One end of each of the four pipes 1 is inserted into one of the slots 21 and fastened to the connector body 2. The connector is characterized in that: the connector also includes an inner liner tube 3; wherein two slots 21 arranged opposite to each other are connected to each other through a connecting channel 22 located inside the connector body 2, the inner liner tube 3 passes through the connecting channel 22 and both ends of the inner liner tube 3 are respectively inserted into the ends of two pipes 1 at corresponding positions, the outer side wall of the end of the inner liner tube 3 is in contact with the inner side wall of the end of the pipe 1, and the inner liner tube 3 is fastened to both the pipe 1 and the connector body 2.
[0032] The outer wall of the inner liner tube 3 is in contact with the inner wall of the connecting channel 22. With this structure, after the inner liner tube is inserted into the connecting channel, the radial movement of the inner liner tube can be limited to avoid radial displacement of the inner liner tube, thereby improving the stability of the inner liner tube and the connecting body after assembly. Preferably, the outer wall of the inner liner tube is tightly fitted with the inner wall of the connecting channel, thereby further limiting the radial displacement of the inner liner tube and limiting the axial position of the inner liner tube after it is inserted into the connecting channel. Thus, when the end of the inner liner tube is inserted into the end of the pipe, axial displacement of the inner liner tube can be avoided.
[0033] Pipe 1 is a round pipe, and the shape of slot 21 is adapted to the shape of pipe 1.
[0034] The end of each pipe 1 is fastened to the connector body 2 by a screw 4. The screw 4 passes through the connector body 2 located on one side of the slot 21 and through the side wall of the pipe 1. The screw 4 is threadedly fastened to the connector body 2 and the pipe 1. With this structure, the end of each pipe can be reliably fastened to the connector body by the screw at the corresponding position.
[0035] The two ends of the inner liner tube 3 are fastened to the tube 1 and the connector body 2 by screws 4 at corresponding positions; with this structure, both ends of the inner liner tube can be fastened together with the tube and connector body by screws at corresponding positions.
[0036] Each slot 21 has an annular guide surface 24 on its inner wall at the outer end. The annular guide surface 24 is used to guide the end of the pipe 1 so that the end of the pipe 1 can be inserted into the slot 21. With this structure, when the end of the pipe is inserted into the slot, the annular guide surface can guide the end of the pipe so that the end of the pipe can be inserted into the slot, which makes it convenient for the end of the pipe to be inserted into the slot.
[0037] The inner lining pipe 3 is a steel pipe; by using steel pipe to make the inner lining pipe, it has the advantages of high bending strength and high deformation strength.
[0038] Pipe 1 is a metal-coated plastic pipe; by using metal-coated plastic pipe as the pipe material, it has the advantages of high pipe strength and high rigidity, that is, it can withstand a large weight and external force, and can effectively prevent the pipe from rusting. In addition, there is no need to spray or electroplat the pipe material, which has the advantage of being environmentally friendly. Furthermore, in this application, the pipe material used is a plastic-coated steel pipe.
[0039] Implementation Method 2
[0040] See Figure 6-10 As shown, in this embodiment, the difference from embodiment one is:
[0041] Pipe 1 is a square tube, and the shape of slot 21 is adapted to the shape of pipe 1.
[0042] A limiting structure is provided on the inner wall of the connector body 2 located outside the connecting channel 22. The two ends of the limiting structure are respectively used to abut against the ends of the pipe 1 on the corresponding side. With this structure, after the end of the pipe is inserted into the slots located at both ends of the connecting channel, the end of the pipe can abut against the limiting structure, thereby limiting the pipe and the connector body. This facilitates the assembly of the pipe and the connector body and improves the reliability and stability of the assembled pipe and connector body.
[0043] The limiting structure includes several limiting blocks 23 arranged circumferentially on the inner wall of the connector body 2. With this structure, after the end of the pipe is inserted into the slots located at both ends of the connection channel, the end of the pipe can abut against the several limiting blocks, thereby limiting the pipe and the connector body. This facilitates the assembly of the pipe and the connector body and improves the reliability and stability of the assembled pipe and connector body.
