Description

Technical Field

[0001] The utility model belongs to the technical field of pipelines, and in particular relates to a pipeline connector. Background Art

[0002] Pipelines are used to transport fluids (liquids or gases) from one location to another. During pipeline construction, due to the limited length of a single pipeline, it is necessary to set up a construction plan in which multiple pipelines are laid out end to end. Therefore, multiple pipelines need to be connected together, and connectors are needed at the joints between the previous pipeline and the next pipeline. Only by relying on pipe connectors can the previous pipeline and the next pipeline be connected together.

[0003] Since the existing pipe connectors on the market have relatively simple functions and are not convenient to change the inclination angle of the connectors, when there is an angle between the two adjacent pipes in front and behind (there are regular angles and special angles), the two adjacent pipes in front and behind are not on the same straight line, and it is necessary to select connectors with a curved shape that is consistent with the angle between the two adjacent pipes in front and behind. When the angle between the two adjacent pipes in front and behind changes, the inclination angle of the connector used will also change, and the connector with the corresponding angle needs to be replaced. If there is no connector with this angle, it needs to be customized, which causes inconvenience during use. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problem that the existing pipe connectors are easily affected by angles during installation, causing inconvenience during installation.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a pipe connector, including a connecting assembly, the connecting assembly includes a first connecting member and a second connecting member, the first connecting member is located to the right of the second connecting member, and the first connecting member and the second connecting member are rotatably connected;

[0006] A first through hole is formed at the right end of the first connecting member, a second through hole is formed at the left end of the second connecting member, and a placement groove is formed outside the first through hole and the second through hole, and the placement groove is respectively located at the outer ends of the second connecting member and the first connecting member;

[0007] The left end of the first connecting member is respectively provided with a plurality of annularly distributed engaging teeth and limiting grooves, wherein the engaging teeth are located between two adjacent limiting grooves;

[0008] A rotation adjustment hole is provided on the top of the second connecting member and is connected to the interior of the second connecting member. An adjustment limit member is slidably connected to the interior of the rotation adjustment hole. The upper and lower ends of the adjustment limit member respectively pass through the upper and lower ends of the rotation adjustment hole. The outer surface of the adjustment limit member is provided with a spring placed inside the rotation adjustment hole. A limiting boss is fixed to the lower end of the adjustment limit member and is placed inside between the first connecting member and the second connecting member. The limiting boss is embedded in the interior of one of the adjacent limiting grooves.

[0009] Particularly, a locking groove is provided at the left end of the first connecting member, and a locking boss aligned with the locking groove is provided at the right end of the second connecting member. The locking boss is embedded in the locking groove, and the locking teeth and the limiting groove are annular in shape.

[0010] In particular, a pipe connector is characterized in that: a fixing screw group is interspersed between the first through hole and the second through hole, the middle side of the fixing screw group passes through the interior between the second connector and the first connector, and the left and right sides of the fixing screw group respectively pass through the outer ends of the second connector and the first connector, and the placement grooves are respectively arranged around the outer periphery of the left and right ends of the fixing screw group, and the left and right ends of the fixing screw group are respectively installed with nut fixings and stud fixings located at the outer ends of the second connector and the first connector.

[0011] Particularly, the interior of the placement groove is provided with spring pieces which are respectively inserted into the left and right ends of the fixing screw assembly, and the spring pieces are located between the nut fixing piece and the stud fixing piece.

[0012] Particularly, a plurality of the connecting assemblies are provided, and a pipe member is installed between two adjacent connecting assemblies.

[0013] Particularly, the outer surface of the limiting boss is adapted to the shape of the inner wall of any one of the limiting grooves, and the spring force is greater than the friction force of the adjustment limiting member sliding on the inner wall of the rotating adjustment hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The first connecting member and the second connecting member form a complete connecting assembly. The connecting assembly connects two adjacent pipe members so that the pipe members are located between the two adjacent connecting members. Multiple connecting members connect multiple pipe members end to end.

[0016] Use your finger to press the adjustment limit piece downward along the inside of the rotation adjustment hole. The adjustment limit piece compresses the spring in the rotation adjustment hole, and the adjustment limit piece allows the limit boss to move downward and disengage from the adjacent limit groove. As a result, the engaging boss can be rotated around the center of the circle between the first connecting piece and the second connecting piece in the engaging groove to change the angle between the first connecting piece and the second connecting piece on the same connecting assembly. This allows the angle between two adjacent pipe pieces to be adjusted quickly and conveniently without disassembling the pipe piece. The operation is simple, fast and efficient.

[0017] After changing the angle of the connection between the connecting assembly and the pipe fitting, loosen the adjustment limit piece with your fingers. The spring originally compressed by the adjustment limit piece will reset the adjustment limit piece through the rebound force, so that the adjustment limit piece will automatically fit the limit boss tightly with the adjacent limit groove, so that the first connecting piece and the second connecting piece after adjustment can be quickly stabilized again.

The limiting boss 140 is embedded in one of the adjacent limiting grooves 102; the left end of the first connecting member 10 is provided with a snap-fit ​​groove 103, and the right end of the second connecting member 11 is provided with a snap-fit ​​boss 113 aligned with the snap-fit ​​groove 103. The snap-fit ​​boss 113 is aligned with the inside of the snap-fit ​​groove 103, and the snap-fit ​​boss 113 is embedded in the To the inside of the engaging groove 103, the engaging teeth 101 and the limiting groove 102 are annular in shape, and the outer surface of the limiting boss 140 is adapted to the shape of the inner wall of any limiting groove 102. The engaging groove 103 at the left end of the first connecting member 10 and the engaging boss 113 at the right end of the second connecting member 11 are tightly fastened to each other, so that the limiting boss 140 contacts the inside of any adjacent limiting groove 102, and the engaging boss 113 is embedded in the engaging groove 103. The first connecting member 10 and the second connecting member 11 are in close contact and connected;

[0027] A fixing screw group 13 is inserted between the first through hole 100 and the second through hole 111. The middle side of the fixing screw group 13 passes through the interior between the second connecting member 11 and the first connecting member 10. The left and right sides of the fixing screw group 13 respectively pass through the outer end of the second connecting member 11 and the outer end of the first connecting member 10. The placement grooves 110 are respectively arranged around the left and right ends of the fixing screw group 13. The left and right ends of the fixing screw group 13 are respectively installed with nut fixing members 130 and stud fixing members 131 located at the outer ends of the second connecting member 11 and the first connecting member 10. The placement grooves 110 are respectively provided with spring pieces 12 that are respectively inserted into the left and right ends of the fixing screw group 13. The spring pieces 12 are located between the nut fixing members 130 and the stud fixing members 131. The stud fixing member 131 is passed through between the first through hole 100 and the second through hole 111, so that the stud fixing member 131 passes through the interior between the first connecting member 10 and the second connecting member 11. The left and right ends of the fixing member 131 respectively pass through the outer ends of the second connecting member 11 and the first connecting member 10, and the fixing screw group 13 is passed through the first connecting member 10 and the second connecting member 11, and the elastic pieces 12 are respectively inserted into the left and right ends of the stud fixing member 131. The elastic pieces 12 are respectively in contact with the inner parts of the placement grooves 110 at the outer ends of the second connecting member 11 and the first connecting member 10, and the placement grooves 110 serve to accommodate the elastic pieces 12. Since matching nuts are provided at the left and right ends of the stud fixing, the nuts are respectively screwed into the outer ends of the elastic pieces 12 from the left and right ends of the stud fixing. After tightening the nuts, the nuts are tightly attached to the outer surfaces of the elastic pieces 12. The nuts are respectively in close contact with the outer ends of the first connecting member 10 and the second connecting member 11, thereby limiting the movement of the fixing screw group 13 between the first pipe member 2 and the second pipe member 2. The fixing screw group 13 is used to keep the first connecting member 10 and the second connecting member 11 tightly connected to form a complete connection assembly 1;

[0028] The right end of the fixing screw assembly 13 is screwed into the surface of the stud fixing member 131, and the stud fixing member 131 blocks the right spring piece 12. After the stud fixing member 131 is installed on the supporting object, the fixing screw assembly 13 is maintained stable by relying on the stud fixing member 131. Then, the nut fixing member 130 is screwed into the left end of the fixing screw assembly 13. The nut fixing member 130 contacts the surface of the second connecting member 11 and blocks the left spring piece 12. The nut fixing member 130 and the stud fixing member 131 can further reinforce the left end of the stud fixing member 131 on the one hand, and can also serve as a decoration for the left end of the stud fixing member 131 on the other hand.

[0029] The first connecting member 10 and the second connecting member 11 constitute a complete connecting assembly 1 as a whole. There are multiple connecting assemblies 1. A pipe member 2 is installed between two adjacent connecting assemblies 1. The connecting assembly 1 connects the two adjacent pipe members 2 so that the pipe member 2 is located between the two adjacent connecting assemblies 1. Multiple connecting assemblies 1 connect multiple pipe members 2 end to end.

[0030] When it is necessary to adjust the angle between any two adjacent pipe members 2, loosen the nuts at the left and right ends of the fixing screw group 13, press the adjustment limiter 14 downward along the inside of the rotation adjustment hole 112 with your fingers, and the adjustment limiter 14 slides downward inside the rotation adjustment hole 112. The adjustment limiter 14 causes the limiting boss 140 to move downward, and the spring 141 is squeezed by the downward sliding adjustment limiter 14. The adjustment limiter 14 causes the spring 141 to be compressed in the rotation adjustment hole 112, and the limiting boss 140 moves downward as the adjustment limiter 14 moves downward. The adjustment limiter 14 allows the limiting boss 140 to move downward. 140 is disengaged from the adjacent limiting groove 102 downward, and the first pipe member 2 and the second pipe member 2 are rotated in opposite directions, so that the engaging boss 113 can rotate inside the engaging groove 103 around the center of the circle between the first connecting member 10 and the second connecting member 11, and the placement state between the first pipe member 2 and the second pipe member 2 is changed, thereby changing the angle between the first connecting member 10 and the second connecting member 11 on the same connecting assembly 1. The angle between the two adjacent pipe members 2 can be adjusted quickly and conveniently without disassembling the pipe members 2, and the operation is simple, fast and efficient.

[0031] After changing the angle between the connection component 1 and the pipe member 2, loosen the adjustment limit piece 14 with your fingers. The elastic force of the spring 141 is greater than the friction force of the adjustment limit piece 14 sliding on the inner wall of the rotating adjustment hole 112. The spring 141 originally compressed by the adjustment limit piece 14 has a rebound force, so that the spring 141 originally compressed by the adjustment limit piece 14 resets the adjustment limit piece 14 through the rebound force. The limiting boss 140 may first contact the engaging tooth 101 without contacting the inside of the limiting groove 102. It is necessary to manually rotate the first pipe member 2 and the second pipe member 2 slightly in the clockwise and counterclockwise directions to allow the engaging boss 113 to rotate slightly along the inside of the engaging groove 103. The limiting boss 140 rubs and moves along the surface of the engaging tooth 101 until the limiting boss 140 is aligned with the adjacent engaging tooth 101, and the limiting boss 140 is released from the engaging tooth 101. The surface of the engaging tooth 101 is pushed into the adjacent limiting groove 102, thereby making a "click" sound and producing a slight vibration feel. The "click" sound can be used to determine whether the limiting boss 140 is fully engaged with the adjacent limiting groove 102. Therefore, the "click" vibration feel can be used to make the adjustment limit member 14 automatically fit the limiting boss 140 tightly with the adjacent limiting groove 102. If the first connecting member 10 and the second connecting member 11 are made of transparent material, the internal structure of the connecting component 1 can be visually observed, so that the angle adjustment effect is better. Re-tighten the nuts at the left and right ends of the fixing screw group 13, so that the adjusted first connecting member 10 and the second connecting member 11 can be quickly re-stabilized, and the bending angle of the connecting component 1 can be flexibly adjusted in a variety of occasions to suit the laying of pipe members 2 in different directions without customization.

[0032] Working principle:

[0033] (1) The first connecting member 10 and the second connecting member 11 constitute a complete connecting component 1 as a whole. A pipe member 2 is installed between two adjacent connecting components 1. The connecting component 1 connects the two adjacent pipe members 2. When it is necessary to adjust the angle between any two adjacent pipe members 2, loosen the nuts on the left and right ends of the fixing screw group 13, and use your fingers to press the adjustment limit member 14 downward along the inside of the rotation adjustment hole 112. The adjustment limit member 14 slides downward inside the rotation adjustment hole 112, and the adjustment limit member 14 causes the limiting boss 140 to move downward. The spring 141 is squeezed by the downwardly sliding adjustment limit member 14, and the adjustment limit member 14 causes the spring 141 to rotate in the rotation adjustment hole 11. 2 is compressed, and the limiting boss 140 moves downward as the adjusting limiting member 14 moves downward. The adjusting limiting member 14 allows the limiting boss 140 to move downward out of the adjacent limiting groove 102, and the first pipe member 2 and the second pipe member 2 are rotated in opposite directions, so that the engaging boss 113 can rotate inside the engaging groove 103 around the center of the circle between the first connecting member 10 and the second connecting member 11, and the placement state between the first pipe member 2 and the second pipe member 2 changes, thereby changing the angle between the first connecting member 10 and the second connecting member 11 on the same connecting assembly 1. The angle between the two adjacent pipe members 2 can be adjusted quickly and conveniently without disassembling the pipe member 2;

[0034] (2) After changing the angle between the connection component 1 and the pipe component 2, loosen the adjustment limiter 14 with your fingers. The elastic force of the spring 141 is greater than the friction force of the adjustment limiter 14 sliding on the inner wall of the rotating adjustment hole 112. The spring 141 originally compressed by the adjustment limiter 14 has a rebound force, so that the spring 141 originally compressed by the adjustment limiter 14 resets the adjustment limiter 14 through the rebound force. The limiting boss 140 may first contact the engaging tooth 101 without contacting the inside of the limiting groove 102. It is necessary to manually rotate the first pipe component 2 and the second pipe component 2 slightly in opposite directions to each other, so that the engaging boss 113 can rotate slightly along the inside of the engaging groove 103. The limiting boss 140 rubs and moves along the surface of the engaging tooth 101 until the limiting boss 14 0 is aligned with the adjacent engaging tooth 101, and the limiting boss 140 is pushed from the surface of the engaging tooth 101 into the adjacent limiting groove 102, thereby making a "click" sound and generating a slight vibration feel. The "click" sound can be used to judge whether the limiting boss 140 is fully engaged with the adjacent limiting groove 102. Therefore, the "click" vibration feel can be used to make the adjustment limit member 14 automatically fit the limiting boss 140 tightly with the adjacent limiting groove 102. If the first connecting member 10 and the second connecting member 11 are made of transparent material, the internal structure of the connecting component 1 can be visually viewed, which makes the angle adjustment effect better. Re-tighten the nuts at the left and right ends of the fixing screw group 13, so that the adjusted first connecting member 10 and the second connecting member 11 can be quickly re-stabilized.
