[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restricts the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0040] As Figures 1 to 4 shown, an embodiment of the present invention provides a pipeline connection device, which is characterized in that it includes:

[0041] A fixed seat 10, the fixed seat 10 has a groove 11;

[0042] A moving part 20, at least a part of the moving part 20 is arranged in the groove 11, the moving part 20 includes two moving blocks 21, and the two moving blocks 21 move along the length direction of the groove 11;

[0043] Two clamping parts 30, the two clamping parts 30 are respectively connected to the two moving blocks 21, and the clamping parts 30 are used for clamping the pipeline 1;

[0044] A support part 40, the support part 40 is fixedly connected to the bottom of the fixed seat 10, and the support part 40 is used for supporting the fixed seat 10.

[0045] Adopting this solution, the moving part 20 is arranged in the groove 11, and the two moving blocks 21 drive the clamping part 30 to move along the length direction of the groove 11, so that the pipeline 1 clamped by the two clamping parts 30 moves with the clamping part 30 to be connected to each other. The support part 40 supports the fixed seat. When the liquid flowing through the pipeline 1 generates oscillation, the support part 40 supports the pipeline 1, the fixed seat 10, the clamping part 30 and the moving part 20, avoiding the instability of the pipeline 1 due to oscillation. Through the pipeline connection device provided by this solution, the problem of unstable connection of chemical pipelines is solved.

[0046] As Figure 1 shown, the moving part 20 further includes a connecting rod 22, the connecting rod 22 is arranged in the groove 11, the connecting rod 22 passes through the moving block 21, and the groove 11 limits the moving block 21 to prevent the moving block 21 from rotating around the connecting rod 22. The connecting rod 22 drives the two moving blocks 21 to move towards or away from each other along the length direction of the connecting rod 22.

[0047] With such a setting, the connecting rod 22 passes through the moving block 21, causing the moving blocks 21 to move towards each other along the length direction of the connecting rod 22, so as to move the clamping parts 30 fixed on the moving blocks 21 towards each other, enabling the pipelines 1 to be connected to each other. The groove 11 limits the moving block 21, such that the moving block 21 cannot rotate and can only move along the length direction of the connecting rod 22. The connecting rod 22 can drive the two moving blocks 21 to move towards or away from each other along the length direction of the connecting rod 22, so that the clamping parts 30 fixedly connected to the moving blocks 21 move towards or away from each other.

[0048] Further, in a specific embodiment of the present invention, the connecting rod 22 has an external thread, the moving block 21 has a threaded hole, the connecting rod 22 is in threaded engagement with the moving block 21, the connecting rod 22 is rotatably connected to the fixed seat 10, and the connecting rod 22 rotates to drive the two moving blocks 21 to move towards or away from each other.

[0049] With such a setting, the connecting rod 22 is in threaded engagement with the moving block 21. When the connecting rod 22 rotates in one direction, it drives the two moving blocks 21 to move towards each other along the length direction of the connecting rod 22; when the connecting rod 22 rotates in the reverse direction, it drives the two moving blocks 21 to move away from each other along the length direction of the connecting rod 22.

[0050] In a specific embodiment of the present invention, the thread helix directions of the threaded holes of the two moving blocks 21 are opposite.

[0051] With such a setting, the thread helix directions of the threaded holes of the two moving blocks 21 are opposite. When the two moving blocks 21 are simultaneously arranged on the connecting rod 22, the rotation of the connecting rod 22 causes the moving directions of the two moving blocks 21 to be opposite, enabling the two moving blocks 21 to move towards or away from each other.

[0052] Alternatively, in a specific embodiment of the present invention, the external thread of the connecting rod 22 includes adjacent first and second thread segments with opposite thread helix directions. The first and second thread segments are respectively in threaded engagement with the threaded holes of one of the moving blocks 21.

[0053] With such a setting, the first and second thread segments have opposite thread helix directions, and the moving directions of the moving block 21 engaged with the first thread segment and the moving block 21 engaged with the second thread segment are opposite. When the connecting rod 22 rotates in one direction, the two moving blocks 21 move towards each other; when the connecting rod 22 rotates in the reverse direction, the two moving blocks 21 move away from each other.

[0054] As Figure 1 shown, the moving part 20 further includes a handle 23. The handle 23 passes through the side wall of the fixed seat 10 and is fixedly connected to the connecting rod 22, and the handle 23 drives the connecting rod 22 to rotate.

[0055] Set up like this, the handle 23 passes through the side wall of the fixed seat 10 and is fixedly connected to the connecting rod 22. By rotating the handle 23, the rotation of the connecting rod 22 can be controlled.

[0056] As Figure 2 shown, the clamping part 30 includes two clamping plates 31. The clamping plates 31 are arc-shaped. The two clamping plates 31 are rotatably connected, and the two clamping plates 31 clamp the pipeline 1.

[0057] Set up like this, the two clamping plates 31 are rotatably connected. After the two clamping plates 31 are opened, the pipeline 1 is placed inside the clamping plates 31, and the two clamping plates 31 are closed to clamp the pipeline 1.

[0058] As Figure 2 shown, the clamping part 30 further includes a fastener 32 and a pin shaft 33. The clamping plate 31 includes an arc-shaped plate 311, a protrusion 312, and a lug 313. The protrusion 312 is fixedly connected to a side edge of the arc-shaped plate 311. The pin shaft 33 is arranged through the protrusion 312 so that the two arc-shaped plates 311 are rotatably connected. The lug 313 is connected to the other side edge of the arc-shaped plate 311. The fastener 32 connects the lugs 313 of the two clamping plates 31 to clamp the pipeline 1.

[0059] Set up like this, the protrusion 312 is fixedly connected to a side edge of the arc-shaped plate 311. The pin shaft 33 is arranged through the protrusion 312, so that one side edge of the two arc-shaped plates 311 with the protrusion 312 is rotatably connected. The other side edge of the arc-shaped plate 311 is provided with a lug 313. The fastener 32 fixedly connects the two lugs 313, so as to buckle the two arc-shaped plates 311 to clamp the pipeline 1.

[0060] As Figure 4 shown, the support part 40 includes a support rod 41 and a cone 42. One end of the support rod 41 is connected to the fixed seat 10, and the other end of the support rod 41 is connected to the cone 42. The cone 42 is inserted into the ground.

[0061] Set up like this, one end of the support rod 41 is connected to the fixed seat 10, and the other end of the support rod 41 is connected to the cone 42 to support the fixed seat 10 to the height of the pipeline 1. The cone 42 is inserted into the ground to make the support of the support rod 41 more stable.

[0062] As Figure 4As shown, in a specific embodiment of the present utility model, the support portion 40 further includes a protective housing 43, a motor 47, a threaded cone block 44, and a plurality of sliders 45. The protective housing 43 is sleeved outside the support rod 41 and the threaded cone block 44. The end of the protective housing 43 is fixedly connected to the fixed seat 10. The protective housing 43 circumferentially limits the threaded cone block 44. The plurality of sliders 45 are arranged along the circumference of the cone 42, and the sliders 45 are in sliding fit with the upper surface of the cone 42. The motor 47 is connected to the fixed seat 10, and the motor 47 is drivingly connected to one end of the support rod 41 away from the cone 42. The support rod 41 has an external thread, and the support rod 41 is in threaded fit with the threaded cone block 44. The end with a smaller diameter of the threaded cone block 44 faces the cone 42. The threaded cone block 44 moves along the support rod 41, and the threaded cone block 44 moves downward to push out the plurality of sliders 45.

[0063] With such a setting, the protective housing 43 plays a protective role for the motor 47 and the threaded cone block 44, preventing the liquid in the pipeline 1 from dripping from above and corroding the motor 47 and the threaded cone block 44. By using the threaded cone block 44 to push out the sliders 45, it avoids the corrosion of the liquid that is likely to drip during manual implementation.

[0064] As Figure 4 shown, the support portion 40 further includes a limit key 46. The limit key 46 is arranged on the outer periphery of the end of the threaded cone block 44 away from the cone 42. The inner wall of the protective housing 43 has a limit groove 431, and the limit groove 431 is in sliding fit with the limit key 46. The limit groove 431 circumferentially limits the threaded cone block 44.

[0065] With such a setting, the limit key 46 is in sliding fit with the limit groove 431, and the limit key 46 circumferentially limits the threaded cone block 44, so that the threaded cone block 44 cannot rotate and can only move along the length direction of the support rod 41.

[0066] As Figure 3 shown, the pipeline connection device further includes a first connector 50 and a second connector 60. The first connector 50 is connected to the end of one side of the pipeline 1, and the second connector 60 is connected to the end of the other side of the pipeline 1. The first connector 50 and the second connector 60 are in plug-in fit to connect the two pipelines 1.

[0067] With such a setting, the first connector 50 and the second connector 60 are in plug-in fit, so that the two pipelines 1 are connected to each other.

[0068] As Figure 1 and Figure 3As shown in the figure, the first connector 50 includes a male connector 51 and a plurality of clamping posts 52. The plurality of clamping posts 52 are circumferentially distributed along the male connector 51. The second connector 60 has a female socket 61 which is in plug-in fit with the male connector 51. The second connector 60 has a plurality of clamping holes 62 which are circumferentially distributed along the outer periphery of the female socket 61. The clamping posts 52 are plugged into the clamping holes 62, and the plurality of clamping posts 52 correspond to the plurality of clamping holes 62 one by one.

[0069] With such a setting, the male connector 51 and the female socket 61 are in plug-in fit, making the connection between the two pipelines 1 more tight and not prone to liquid leakage, ensuring the sealing and safety of the connection. The plurality of clamping posts 52 and the plurality of clamping holes 62 correspond to each other one by one. The connection between the clamping posts 52 and the clamping holes 62 increases the sealing and safety of the connection, and the connection between the clamping posts 52 and the clamping holes 62 prevents the connection between the male connector 51 and the female socket 61 from loosening.
