[0001] The present invention relates to the technical field of pipeline connection, and particularly to a pipeline connection structure for HVAC construction. Background Art

[0002] HVAC pipelines are pipelines in the HVAC system that facilitate the normal operation of heating, ventilation, air conditioning, or water supply and drainage. When connecting HVAC pipelines, the end faces of two HVAC pipelines need to be aligned and fitted.

[0003] After retrieving the Chinese patent with the publication number CN221540691U, it discloses a pipeline connection structure for HVAC construction, including: a base, on the top of which there are fixedly installed a fixed seat and a connection seat arranged oppositely, and on the opposite side walls of the fixed seat and the connection seat, there are provided limiting sliding rods; a movable seat, which is arranged between the fixed seat and the connection seat and can move back and forth along the axial direction of the limiting sliding rods.

[0004] Based on the above retrieval and in combination with the prior art, it is found that:

[0005] During the construction of existing HVAC construction pipelines, docking is required. Most of the time, during the process of pulling the pipelines for docking, due to the insufficient fixation of the pipelines, the pipelines are prone to slipping, thus affecting the docking effect of the pipelines. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention proposes a pipeline connection structure for HVAC construction. When the upper clamping plate and the lower clamping plate clamp and fix the pipeline, after melting one end of the docking of the two pipelines with a hot melt device, during the process of docking the two pipelines, at the same time, the movement of the upper clamping plate drives the movement of the sliding frame and the L-shaped sliding rod, so that the L-shaped sliding rod contacts the bending plate, and the extrusion spring drives the L-shaped sliding rod and the pressing block to move downward through the bending plate, so that the pressing block presses the pipeline tightly, achieving an improved fixing effect on the pipeline and preventing the pipeline from slipping during the process of pulling the pipeline.

[0007] The technical solution for achieving the purpose of the present invention is: a pipeline connection structure for HVAC construction, including a bottom plate, on the top of which there are fixedly connected two fixing plates, and on the top of the two fixing plates there is fixedly connected a fixing frame, and further including;

[0008] A docking mechanism, which is located on the fixing plate;

[0009] The docking mechanism includes two fixed rods fixedly connected between two fixing plates. A fixed seat is fixedly connected to the two fixed rods. A sliding seat is slidably connected to the two fixed rods. Lower clamping plates are fixedly connected to the tops of the sliding seat and the fixed seat. Upper clamping plates are arranged above the two lower clamping plates. A sliding frame is fixedly connected to one of the upper clamping plates. An L-shaped sliding rod is slidably connected in the sliding frame. A pressing block is fixedly connected to the bottom end of the L-shaped sliding rod. Two connecting rods are slidably connected to the fixed frame. A bent plate is connected to the bottom ends of the two connecting rods. The L-shaped sliding rod is adapted to the bent plate. Extrusion springs are sleeved on the two connecting rods. The two ends of the extrusion springs are fixedly connected to the fixed frame and the bent plate respectively.

[0010] In some embodiments, a return spring is sleeved on the L-shaped sliding rod. The two ends of the return spring are fixedly connected to the pressing block and the sliding frame respectively.

[0011] In some embodiments, a servo motor is fixedly connected to the top of the bottom plate. The output end of the servo motor is fixedly connected to a threaded rod. One end of the threaded rod is rotatably connected to the fixed seat. The sliding seat is screwed onto the threaded rod.

[0012] In some embodiments, an electric telescopic rod is fixedly connected to the top of the fixed frame. The output end of the electric telescopic rod is fixedly connected to a bracket. The bottom end of the bracket is fixedly connected to the other upper clamping plate. The sliding frame is slidably connected to the bracket.

[0013] In some embodiments, two limiting rods are fixedly connected to the two lower clamping plates. The two upper clamping plates are respectively slidably connected to the four limiting rods.

[0014] In some embodiments, placing grooves are formed in the two fixing plates.

[0015] Compared with the prior art, the remarkable advantages of this utility model are:

[0016] Through the setting of the docking mechanism of the present invention, two pipes to be connected are placed on the two lower clamping plates. When the upper clamping plate and the lower clamping plate clamp and fix the pipes, after melting one end of the butt joint of the two pipes with a hot melt tool, during the process of docking the two pipes, at the same time, the upper clamping plate moves to drive the sliding frame and the L-shaped sliding rod to move, so that the L-shaped sliding rod contacts the bent plate, and the extrusion spring drives the L-shaped sliding rod and the pressing block to move downward through the bent plate, so that the pressing block presses the pipe, realizing the improvement of the fixing effect on the pipe, and preventing the pipe from slipping during the pulling process;

[0024] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a pipeline connection structure for HVAC construction by improvement. The technical solution of the present invention is:

[0026] Such as Figures 1-3As shown in the figure, a pipeline connection structure for HVAC construction includes a bottom plate 1. Two fixing plates 11 are fixedly connected to the top of the bottom plate 1. A fixing frame 2 is fixedly connected to the top of the two fixing plates 11. It also includes a docking mechanism, and the docking mechanism is located on the fixing plates 11. The docking mechanism includes two fixing rods 12 fixedly connected between the two fixing plates 11. The fixing rods 12 are fixed to the fixing plates 11 by welding, making the fixing rods 12 more firm. A fixing seat 13 is fixedly connected to the two fixing rods 12. A sliding seat 14 is slidably connected to the two fixing rods 12. Lower clamping plates 15 are fixedly connected to the tops of the sliding seat 14 and the fixing seat 13. Upper clamping plates 18 are provided above the two lower clamping plates 15. A sliding frame 23 is fixedly connected to one of the upper clamping plates 18. An L-shaped sliding rod 3 is slidably connected in the sliding frame 23. A pressing block 33 is fixedly connected to the bottom end of the L-shaped sliding rod 3. Two connecting rods 31 are slidably connected to the fixing frame 2. The bottom ends of the two connecting rods 31 are commonly connected to a bent plate 32. The L-shaped sliding rod 3 is adapted to the bent plate 32. Extrusion springs 35 are sleeved on the two connecting rods 31. The two ends of the extrusion springs 35 are respectively fixedly connected to the fixing frame 2 and the bent plate 32. Through the setting of the docking mechanism, the two pipelines to be connected are placed on the two lower clamping plates 15. When the upper clamping plates 18 and the lower clamping plates 15 clamp and fix the pipelines, after melting one end of the butt joint of the two pipelines with a hot melt machine, during the process of docking the two pipelines, at the same time, the upper clamping plate 18 moves to drive the sliding frame 23 and the L-shaped sliding rod 3 to move, so that the L-shaped sliding rod 3 contacts the bent plate 32. The extrusion spring 35 drives the L-shaped sliding rod 3 and the pressing block 33 to move downward through the bent plate 32, so that the pressing block 33 presses the pipeline, improving the fixing effect on the pipeline and preventing the pipeline from slipping during the pulling process.

[0027] As Figure 1 shown, in one embodiment, a return spring 34 is sleeved on the L-shaped sliding rod 3. The two ends of the return spring 34 are respectively fixedly connected to the pressing block 33 and the sliding frame 23. Through the setting of the return spring 34, the return spring 34 drives the L-shaped sliding rod 3 and the pressing block 33 to reset.

[0028] As Figure 1 shown, in one embodiment, in order to facilitate the later maintenance of the servo motor 16, the servo motor 16 is fixed by screwing. A servo motor 16 is fixedly connected to the top of the bottom plate 1. The output end of the servo motor 16 is fixedly connected to a threaded rod 17. One end of the threaded rod 17 is rotatably connected to the fixing seat 13. The sliding seat 14 is screwed onto the threaded rod 17. Through the setting of the servo motor 16, starting the servo motor 16 drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 drives the sliding seat 14 to move, so that the sliding seat 14 drives one of the pipelines to move through the upper clamping plate 18 and the lower clamping plate 15, realizing the docking of the two pipelines.

[0029] As Figure 1 shown, in one embodiment, in order to facilitate the later maintenance of the electric telescopic rod 21, the electric telescopic rod 21 is fixed by screwing. The top of the fixing frame 2 is fixedly connected with the electric telescopic rod 21. The output end of the electric telescopic rod 21 is fixedly connected with a bracket 22. The bottom end of the bracket 22 is fixedly connected to another upper clamping plate 18. The sliding frame 23 is slidably connected to the bracket 22. Through the setting of the electric telescopic rod 21, the electric telescopic rod 21 drives the bracket 22 and the sliding frame 23 to move downward, so that the bracket 22 and the sliding frame 23 drive the two upper clamping plates 18 to move downward, so that the upper clamping plates 18 and the lower clamping plates 15 clamp and fix the pipeline, realizing the clamping and fixing of the pipeline.

[0030] As Figure 1 shown, in one embodiment, two limiting rods 19 are fixedly connected to both of the two lower clamping plates 15. The two upper clamping plates 18 are respectively slidably connected to the four limiting rods 19. Through the setting of the limiting rods 19, the stability of the upper clamping plates 18 is improved.

[0031] As Figure 1 shown, in one embodiment, placing grooves 110 are formed in both of the two fixing plates 11. Through the setting of the placing grooves 110, the placement of the pipeline is realized.

[0032] The specific working method is as follows: When in use, place the two pipelines to be connected on the two lower clamping plates 15, start the electric telescopic rod 21 to drive the bracket 22 and the sliding frame 23 to move downward, so that the bracket 22 and the sliding frame 23 drive the two upper clamping plates 18 to move downward, so that the upper clamping plates 18 and the lower clamping plates 15 clamp and fix the pipelines. When one of the upper clamping plates 18 moves downward, it drives the L-shaped sliding rod 3 to move. After melting one end of the butt joint of the two pipelines with a hot melt machine, start the servo motor 16 to drive the threaded rod 17 to rotate. The rotation of the threaded rod 17 drives the sliding seat 14 to move, so that the sliding seat 14 drives one of the pipelines to move through the upper clamping plate 18 and the lower clamping plate 15. At the same time, the movement of the upper clamping plate 18 drives the sliding frame 23 and the L-shaped sliding rod 3 to move, so that the L-shaped sliding rod 3 contacts the bending plate 32. The extrusion spring 35 drives the L-shaped sliding rod 3 and the pressing block 33 to move downward through the bending plate 32. The movement of the pressing block 33 drives the reset spring 34 to stretch and elastically deform, so that the pressing block 33 presses the pipeline, improving the fixing effect on the pipeline and preventing the pipeline from slipping during the pulling process until the melting ends of the two pipelines are butted. After the butting is completed, the electric telescopic rod 21 drives the bracket 22, the sliding frame 23 and the upper clamping plate 18 to move upward. At the same time, the servo motor 16 drives the sliding seat 14, the lower clamping plate 15 and the upper clamping plate 18 to reset through the threaded rod 17, and then take out the butted pipeline.
