DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 10 As shown, a pipeline connection and fastening device according to an embodiment of the present invention comprises an assembly table 1, a tube support recess 2 is symmetrically fixedly installed on the top of the assembly table 1, a tube support recess 7 is symmetrically fixedly installed in the middle of the top of the assembly table 1, a tube fixing tube 3 is placed on the top of the two tube support recesses 7, both ends of the tube fixing tube 3 are rotatably connected with a swivel 4, both ends of the tube fixing tube 3 are fixedly installed with a wire body fixing box 14, the wire body fixing box 14 is used to fasten the tube body of the wire tube, and plays a role in fastening the tube body of the wire tube, a wire end fixing box 13 is fixedly installed in the middle of the outer wall of the tube fixing tube 3, the wire end fixing box 13 is used to fix the tube ends of the two wire tubes, and plays a role in fixing the two wire tubes, and a tube locking push rod 5 is symmetrically arranged on the top of the assembly table 1;

[0035] In the current prior art, when connecting and fastening the wire tube, connectors of different sizes and diameters are usually customized according to the different sizes and diameters of the wire tube. Such connectors cannot be adapted when the wire tube is changed, and a new connector needs to be customized again, which is extremely time-consuming.

[0036] By placing the two ends of the two pipelines on the pipe-supporting recesses 2 at the two ends of the top of the assembly table 1, placing the pipe-fixing tube 3 on the pipe-supporting recess 7 in the middle of the top of the assembly table 1, and inserting the two ends of the two pipelines into the pipe-fixing tube 3, the line end fixing boxes 13 on the pipe-fixing tube 3 connect and fix one end of the two pipelines. When the two ends of the pipelines are connected and fixed, the pipe-locking push rod 5 drives the swivel 4 to rotate, and the two line body fixing boxes 14 fix the two end pipe bodies of the two pipelines at the same time. The line end fixing box 13 connects and fixes the two end pipe bodies and the two ends of the two pipelines respectively, so as to realize the connection and fastening of the two pipelines. Through the unique fastening method of the line end fixing box 13 and the line body fixing box 14, the fixed pipe tube 3 can connect and fasten pipelines of different diameters, and is suitable for pipelines of various specifications, playing a universal role. It should be noted here that the pipeline connected by the fixed pipe tube 3 is a protective pipeline, such as a protective casing outside a cable, a protective casing of a pipe buried underground, etc., and the assembly table 1 is a movable assembly table 1.

[0037] like Figures 2 to 3 As shown, the bottoms of the two locking tube push rods 5 are fixedly mounted with slides 11, the top of the assembly table 1 is symmetrically provided with slide slots 6, the two slides 11 are slidably connected to the inner walls of the two slide slots 6, a connecting plate 8 is fixedly mounted between the two slides 11, a motor 9 is fixedly mounted on one side of the connecting plate 8, and the motor 9 is fixedly mounted on the inner wall of the assembly table 1;

[0038] When the tube locking push rod 5 pushes the swivel 4 to rotate, the motor 9 drives the connecting plate 8 to move. While the connecting plate 8 moves, it drives the two slides 11 to slide in the slide bar groove 6 on the inner wall of the assembly table 1, so that the two slides 11 respectively drive the two tube locking push rods 5 to move on the top of the assembly table 1. While moving, the tube locking push rod 5 pushes the swivel 4 to rotate, so that the swivel 4 drives the two line body fixing boxes 14 to fix the two end pipe bodies of the two pipelines, thereby playing a role of auxiliary tightening.

[0039] like Figures 1 to 4 As shown, the inner walls of the two rotating rings 4 are provided with two groups of push grooves 30, and the tops of the two locking tube push rods 5 are provided with two groups of push blocks 10, and the two groups of push blocks 10 are respectively slidably connected with the inner walls of the two groups of push grooves 30;

[0040] When the lock tube push rod 5 moves, the push block 10 on the lock tube push rod 5 pushes the push groove 30 on the swivel 4 to move, so that when the lock tube push rod 5 moves, the swivel 4 is driven by it to rotate, which plays the role of pushing and rotating the swivel 4. It should be noted here that the positions of the push groove 30 on the swivel 4 and the push block 10 on the lock tube push rod 5 should correspond to each other.

[0041] like Figures 5 to 7 As shown, a plurality of rotating shafts 18 are arranged inside the wire body solid box 14, both ends of the plurality of rotating shafts 18 are rotatably connected to the inner wall of the wire body solid box 14, a plurality of fixed pipe blocks 17 are fixedly installed on the outer walls of the plurality of rotating shafts 18, a plurality of positioning openings 27 are opened on the inner wall of the wire body solid box 14, a plurality of fixed positioning boxes 19 are fixedly installed inside the wire body solid box 14, an arc plate 20 is arranged on the inner walls of the plurality of fixed positioning boxes 19, one end of the plurality of arc plates 20 is respectively fixedly connected to one side of the plurality of fixed pipe blocks 17, the outer walls of the plurality of arc plates 20 are respectively slidably connected to the inner walls of the plurality of positioning openings 27, a plurality of fixed positioning boxes 19 are arranged inside the plurality of shaft rods 15, the plurality of arc plates 20 are respectively hinged to the outer walls of the plurality of shaft rods 15, and one end of the plurality of shaft rods 15 is fixedly connected to the inner wall of the swivel 4;

[0042] When the swivel 4 rotates, the swivel 4 drives the shaft 15 in the line body fixing box 14 to move in the retaining box 19. When the shaft 15 moves, it pushes the arc plate 20 to be limited on the positioning opening 27 and rotate. When the arc plate 20 rotates, it pushes the pipe fixing block 17 to shift and rotate through the rotating shaft 18. When multiple pipe fixing blocks 17 shift and rotate to contact the pipe body of the pipeline, the multiple pipe fixing blocks 17 bind and fix the pipe body. When fixed to a certain extent, the push block 10 on the locking pipe push rod 5 cannot push the push groove 30 on the swivel 4. At this time, the multiple pipe fixing blocks 17 firmly fix the pipe body of the pipeline, which plays a role in fixing the pipeline body. By rotating the swivel 4 to drive the multiple pipe fixing blocks 17 to shift and rotate to fix the pipeline body, the pipe fixing block 17 can fix pipeline bodies of different diameters, adapt to pipelines of different diameters, and play an adjustable role.

[0043] like Figures 7 and 8 As shown, the inner walls of the plurality of shafts 15 are provided with limit openings 22, the inner walls of the plurality of retaining boxes 19 are fixedly mounted with vertical plates 21, the inner walls of the plurality of vertical plates 21 are slidably connected with a group of gear rods 23, one end of the group of gear rods 23 is clamped with the inner wall of the limit opening 22, the inner walls of the plurality of retaining boxes 19 are provided with sliding grooves 28, and the outer walls of the plurality of shafts 15 are slidably connected with the inner walls of the plurality of sliding grooves 28 respectively;

[0044] When the swivel 4 drives the shaft 15 to move, the shaft 15 slides in the slide groove 28 in the retaining box 19. When the shaft 15 slides, the shaft 15 squeezes the toothed rod 23 on the vertical plate 21 to retract inward. When multiple pipe fixing blocks 17 have completed fixing the pipe body of the pipeline, the shaft 15 stops moving. At this time, the shaft 15 loses the extrusion thrust, and one end of the toothed rod 23 will be stuck in the limiting opening 22 in the shaft 15 for limiting and fixing, thereby playing a role in fixing. It should be noted here that the position of the toothed rod 23 corresponds to the position of the limiting opening 22, and the elastic force of the retaining spring 24 and the number of toothed rods 23 need to be actually measured and calculated.

[0045] like Figures 7 and 8 As shown, a retaining spring 24 is fixedly installed on one side of a set of gear rods 23, one end of a set of retaining springs 24 is fixedly connected to the inner wall of the retaining box 19, and one end of a set of gear rods 23 is slidably connected to the inner wall of the retaining box 19;

[0046] When the shaft 15 stops moving, the shaft 15 loses its squeezing force, and the gear rod 23 extends out due to the elastic force of the retaining spring 24. One end of the gear rod 23 is inserted into the limiting opening 22 in the shaft 15, thereby pushing the gear rod 23 to be positioned.

[0047] like Figures 1 to 4 As shown, a handle 12 is symmetrically fixedly mounted on the outer wall of the pipe fixing tube 3;

[0048] When placing the pipe fixing tube 3 , the pipe fixing tube 3 is moved by lifting and releasing the lifting handle 12 , and the setting of the lifting handle 12 facilitates the movement of the pipe fixing tube 3 .

[0049] like Figures 5 to 9 As shown, the inner wall of the pipe fixing tube 3 is provided with a plurality of sliding openings 29, and the interior of the line end fixing box 13 is provided with a plurality of pipe clamping blocks 16, and the outer walls of the plurality of pipe clamping blocks 16 are respectively slidably connected with the inner walls of the plurality of sliding openings 29;

[0050] When the pipe ends of the two pipes are inserted into the fixed pipe barrel 3, the pipe ends of the two pipes squeeze the multiple pipe clamping blocks 16 to slide in the sliding opening 29 in the fixed pipe barrel 3. When the pipe ends of the two pipes are inserted to a certain position, the multiple pipe clamping blocks 16 stop moving. At this time, the inner walls of the multiple pipe clamping blocks 16 clamp and fix the pipe ends of the two pipes, thereby playing a role in fixing the pipe ends of the pipes. Through the moving clamping and fixing of the multiple pipe clamping blocks 16, the pipe ends of pipelines with different diameters can be adapted. Through the moving clamping and fixing of the multiple pipe clamping blocks 16 and the shifting and rotating of the multiple fixed pipe blocks 17, the pipe body of the pipeline is fixed. The two are fixed in coordination with each other. While playing a role in connecting and tightening the pipelines, the fixed pipe barrel 3 can also be adapted to pipelines with different diameters, thereby achieving a universal effect.

[0051] like Figures 9 and 10 As shown, a stopper 31 is fixedly mounted on one end of each of the plurality of pipe clamping blocks 16;

[0052] When the two pipes are inserted into the fixed pipe barrel 3, when the pipe ends of the two pipes contact the stopper 31, the two pipes stop being inserted, and then a plurality of pipe clamping blocks 16 fix the pipe ends of the pipes, and the pipe ends of the two pipes are connected through the stopper 31, which plays the role of limiting connection.

[0053] like Figures 9 and 10 As shown, a plurality of sliding limit rods 25 are arranged inside the wire end fixing box 13, a plurality of clamping tube blocks 16 are respectively slidably connected to one end of the plurality of sliding limit rods 25, a plurality of return springs 26 are arranged between the plurality of clamping tube blocks 16 and the inner wall of the wire end fixing box 13, and the plurality of sliding limit rods 25 are respectively placed in the plurality of return springs 26;

[0054] When the pipe end of the pipeline squeezes the pipe clamping block 16 to move, the pipe clamping block 16 squeezes the reset spring 26 to slide on the sliding limit rod 25. When the pipe end of the pipeline contacts the stopper 31, the pipe clamping block 16 loses the squeezing thrust, and the pipe clamping block 16 is returned to its original position by the elastic force of the reset spring 26. The pipe clamping block 16 then clamps and fixes the pipe end of the pipeline, thereby playing the role of resetting and pushing the pipe clamping block 16 to move.

[0055] Working principle: by placing the two ends of the two pipelines on the pipe support recesses 2 at the two ends of the top of the assembly table 1, placing the fixed pipe tube 3 on the support recess 7 in the middle of the top of the assembly table 1, and inserting the two ends of the two pipelines into the fixed pipe tube 3, while inserting, the line end fixing box 13 on the fixed pipe tube 3 connects and fixes one end of the two pipelines. When the two ends of the pipelines are connected and fixed, the locking tube push rod 5 drives the swivel 4 to rotate, and while rotating, the two line body fixing boxes 14 fix the two end pipe bodies of the two pipelines. The two end pipe bodies and the two ends of the two pipelines are connected and fixed by the line body fixing box 14 and the line end fixing box 13 respectively, so as to realize the connection and fastening of the two pipelines. Through the unique fastening method of the line end fixing box 13 and the line body fixing box 14, the fixed pipe tube 3 can connect and fasten pipelines of different diameters, adapt to pipelines of various specifications, and play a universal role.

[0056] When the tube lock push rod 5 pushes the swivel 4 to rotate, the motor 9 drives the connecting plate 8 to move, and the connecting plate 8 moves while driving the two slides 11 to slide in the slide bar groove 6 on the inner wall of the assembly table 1, so that the two slides 11 respectively drive the two tube lock push rods 5 to move on the top of the assembly table 1, and while moving, the tube lock push rod 5 pushes the swivel 4 to rotate, so that the swivel 4 drives the two line body fixing boxes 14 to fix the two ends of the two pipelines, which plays a role of auxiliary tightening;

[0057] When the lock tube push rod 5 moves, the push block 10 on the lock tube push rod 5 pushes the push groove 30 on the rotating ring 4 to move, so that when the lock tube push rod 5 moves, the rotating ring 4 is driven by it to rotate, which plays the role of pushing the rotating ring 4;

[0058] When the swivel 4 rotates, the swivel 4 drives the shaft 15 in the line body fixing box 14 to move in the fixing box 19. When the shaft 15 moves, it pushes the arc plate 20 to be limited on the positioning opening 27 and rotate. When the arc plate 20 rotates, it pushes the pipe fixing block 17 to shift and rotate through the rotating shaft 18. When the multiple pipe fixing blocks 17 shift and rotate to contact the pipe body of the pipeline, the multiple pipe fixing blocks 17 bind and fix the pipe body. When fixed to a certain extent, the push block 10 on the locking pipe push rod 5 cannot push the push groove 30 on the swivel 4. At this time, the multiple pipe fixing blocks 17 firmly fix the pipe body of the pipeline and play a role in fixing the pipe body of the pipeline. By rotating the swivel 4 to drive the multiple pipe fixing blocks 17 to shift and rotate to fix the pipe body of the pipeline, the pipe fixing block 17 can fix the pipe body of pipelines of different diameters, adapt to pipelines of different diameters, and play an adjustable role.

[0059] When the swivel 4 drives the shaft 15 to move, the shaft 15 slides in the slide groove 28 in the retention box 19. When the shaft 15 slides, the shaft 15 squeezes the gear rod 23 on the vertical plate 21 to retract inward. When the multiple pipe fixing blocks 17 have completed fixing the pipe body of the pipeline, the shaft 15 stops moving. At this time, the shaft 15 loses the thrust of squeezing, and one end of the gear rod 23 is inserted into the limit opening 22 in the shaft 15 to limit and fix it, thereby playing a role of retention.

[0060] When the shaft 15 stops moving, the shaft 15 loses the extrusion thrust, and the gear rod 23 is extended by the elastic force of the retaining spring 24, and one end of the gear rod 23 is inserted into the limiting opening 22 in the shaft 15, thereby pushing the gear rod 23 to be locked.

[0061] When placing the pipe fixing tube 3, the pipe fixing tube 3 is moved by lifting and releasing the handle 12. The setting of the handle 12 facilitates the movement of the pipe fixing tube 3.

[0062] When the pipe ends of the two pipes are inserted into the fixed pipe barrel 3, the pipe ends of the two pipes squeeze the multiple clamping blocks 16 to slide in the sliding opening 29 in the fixed pipe barrel 3. When the pipe ends of the two pipes are inserted into a certain position, the multiple clamping blocks 16 stop moving. At this time, the inner walls of the multiple clamping blocks 16 clamp the pipe ends of the two pipes and fix them, which plays a role in fixing the pipe ends of the pipes. Through the moving clamping and fixing of the multiple clamping blocks 16, it can be adapted to the pipe ends of pipelines of different sizes and diameters. Through the moving clamping and fixing of the multiple clamping blocks 16 and the shifting and rotating of the multiple fixed pipe blocks 17, the pipe body of the pipeline is fixed. The two are fixed in coordination with each other. While connecting and tightening the pipelines, the fixed pipe barrel 3 can also be adapted to pipelines of different sizes and diameters, achieving a universal effect.

[0063] When the two pipes are inserted into the fixed pipe barrel 3, when the pipe ends of the two pipes contact the stopper 31, the two pipes stop inserting, and then the pipe ends of the pipes are fixed by the multiple pipe clamping blocks 16, and the pipe ends of the two pipes are connected through the stopper 31, which plays the role of limiting connection;

[0064] When the pipe end of the pipeline squeezes the pipe clamping block 16 to move, the pipe clamping block 16 squeezes the reset spring 26 to slide on the sliding limit rod 25. When the pipe end of the pipeline contacts the stopper 31, the pipe clamping block 16 loses the squeezing thrust, and the pipe clamping block 16 is returned to its original position by the elastic force of the reset spring 26. The pipe clamping block 16 then clamps and fixes the pipe end of the pipeline, thereby playing the role of resetting and pushing the pipe clamping block 16 to move.
