Description

Technical Field

[0001] This utility model relates to the field of hot melt welding clamping technology for communication pipes, and in particular to a hot melt welding clamp for four-hole pipes. Background Technology

[0002] Four-hole communication conduit is a type of communication conduit used for the external protection of communication cables. Due to the limited length of the conduit, multiple conduits need to be spliced ​​together on site to form a long and effective cable laying route. The splicing of four-hole conduits is often achieved using hot-melt welding technology.

[0003] The existing hot-melt welding operation of four-hole pipes often involves manual splicing, which makes the clamping operation of the pipe and the sleeve inconvenient, and the stability of hot-melt welding needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a four-hole pipe hot-melt welding clamp that can be quickly and conveniently clamped and installed on the outside of the pipe, while improving the stability of the pipe and pipe sleeve splicing and providing high flexibility for field use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A four-hole pipe hot-melt welding fixture includes a fixture frame. Each of the symmetrical inner walls of the fixture frame is provided with a sliding groove, and two sliders are slidably installed inside the sliding groove. A clamping seat is fixedly connected to the lower surface of the slider. A rotating mounting hole is provided at each end of the fixture frame, and a lead screw is rotatably installed inside the rotating mounting hole. The lead screw passes through the threaded holes on the side surfaces of the two sliders. A handle is fixedly connected to the middle position of the upper surface of the fixture frame.

[0007] By adopting the above technical solution, the clamp can be conveniently held on the outside of the pipes and sleeves to be spliced, while improving the connection stability of the pipes and sleeves.

[0008] Furthermore, a fixing frame is fixedly connected to one end of the clamp frame, and a linkage rod is rotatably mounted on one end of the fixing frame via a bearing. A second bevel gear is fixedly connected to one end of the linkage rod, and a first bevel gear is fixedly connected to one end of the lead screw. The first bevel gear and the second bevel gear are meshed together.

[0009] By adopting the above technical solution, the first bevel gear and the second bevel gear can be used to make the linkage rod drive the lead screw to rotate.

[0010] Furthermore, the outer surface of the lead screw is provided with two threads in opposite directions, and the two threads in opposite directions are divided at the middle position of the lead screw.

[0011] By adopting the above technical solution, the lead screw can drive the two sliders to move in opposite directions.

[0012] Furthermore, a threaded hole seat is fixedly connected to the side surface of the clamping seat, and a clamping screw is installed in the threaded hole of the threaded hole seat. An inner clamping plate is rotatably installed at one end of the clamping screw, and the upper edge of the inner clamping plate is attached to the inner end face of the clamping seat.

[0013] By adopting the above technical solution, the clamping screw can be turned so that the inner clamping plate moves along the central axis of the clamping screw, thereby clamping and fixing the pipe and sleeve inside the clamping seat.

[0014] Furthermore, the cross-section of the clamping seat is C-shaped.

[0015] By adopting the above technical solution, it is easy to clamp the clamping seat on the outside of the pipe and the sleeve.

[0016] Furthermore, the linkage rod is perpendicular to the lead screw.

[0017] By adopting the above technical solutions, the flexibility of on-site operations can be improved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention allows for the hot-melt welding of two four-hole pipes. By holding the handle and clamping the two clamping seats onto the outside of the pipe and sleeve, one end of the pipe is hot-melted. Then, one end of the linkage rod is turned, causing the second bevel gear to rotate. The second bevel gear then rotates the first bevel gear. Since the first bevel gear is fixedly connected to one end of the lead screw, its rotation drives the lead screw to rotate. Furthermore, because the two sliders are threaded to both ends of the lead screw, the rotation of the lead screw brings the two sliders closer together, allowing the hot-melted end of the pipe to be inserted into the sleeve. The entire clamping operation is quick and convenient, offering high flexibility for on-site use. Attached Figure Description

[0023] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 , Figure 2 A four-hole pipe hot-melt welding fixture includes a fixture frame 1. Each of the symmetrical inner walls of the fixture frame 1 has a sliding groove, and two sliders 3 are slidably mounted inside the groove. A clamping seat 9 is fixedly connected to the lower surface of each slider 3. A rotary mounting hole is provided at each end of the fixture frame 1, and a lead screw 4 is rotatably mounted inside the rotary mounting hole. The lead screw 4 passes through threaded holes on the side surfaces of the two sliders 3. A handle 2 is fixedly connected to the middle position of the upper surface of the fixture frame 1. The clamping seat 9 has a C-shaped cross-section, and two threads in opposite directions are provided on the outer surface of the lead screw 4. The threaded shaft has two opposite threads, with the middle position of the screw 4 as the dividing point. When performing hot-melt welding on two four-hole pipes, hold the handle 2, then attach the two clamping seats 9 to the outside of the pipe and the sleeve. Then perform hot-melt operation on one end of the pipe, and then rotate the screw 4. Since the two sliders 3 are threaded to both ends of the screw 4, the rotation of the screw 4 can bring the two sliders 3 closer to each other, so that one end of the hot-melt pipe can be inserted into the inside of the sleeve. The whole clamping operation can be carried out quickly and conveniently, and is highly flexible in field use.

[0025] Reference Figure 1 One end of the clamp frame 1 is fixedly connected to a fixing frame 6. One end of the fixing frame 6 is rotatably mounted with a linkage rod 7 via a bearing. One end of the linkage rod 7 is fixedly connected to a second bevel gear 8. One end of the lead screw 4 is fixedly connected to a first bevel gear 5. The first bevel gear 5 and the second bevel gear 8 are meshed together. The linkage rod 7 and the lead screw 4 are perpendicularly distributed. When in use, one end of the linkage rod 7 can be turned, which will drive the second bevel gear 8 to rotate, the second bevel gear 8 to rotate, the first bevel gear 5 to rotate, and the first bevel gear 5 to rotate the lead screw 4. This enables effective assembly operations and can adapt to different on-site operating environments, further improving the flexibility of use.

[0026] Reference Figure 2 A threaded hole seat 10 is fixedly connected to the side surface of the clamping seat 9. A clamping screw 11 is installed in the threaded hole of the threaded hole seat 10. An inner clamping plate 12 is rotatably installed at one end of the clamping screw 11. The upper edge of the inner clamping plate 12 is attached to the inner end face of the clamping seat 9. When clamping pipes and sleeves, the pipes and sleeves can be placed inside the clamping seat 9, and then the clamping screw 11 can be turned. Since the clamping screw 11 is threaded inside the threaded hole seat 10, and the inner clamping plate 12 is rotatably connected to the clamping screw 11, and the upper edge of the inner clamping plate 12 is attached to the inner end face of the clamping seat 9, the rotation of the clamping screw 11 can enable the inner clamping plate 12 to perform clamping operation on the pipes and sleeves.

[0027] Working principle: When using, hold handle 2, and then attach the two clamping seats 9 to the outside of the pipe and the sleeve. During installation, turn the clamping screw 11. Since the clamping screw 11 is threaded into the inside of the threaded hole seat 10, the inner clamping plate 12 is rotatably connected to the clamping screw 11. The upper edge of the inner clamping plate 12 is attached to the inner end face of the clamping seat 9. Therefore, the rotation of the clamping screw 11 can make the inner clamping plate 12 clamp the pipe and the sleeve. Then, perform a heat fusion operation on one end of the pipe. Then turn one end of the linkage rod 7. At this time, the linkage rod 7 drives the second bevel gear 8 to rotate, the second bevel gear 8 drives the first bevel gear 5 to rotate, and the first bevel gear 5 drives the screw 4 to rotate. Since the two sliders 3 are threaded to both ends of the screw 4, the rotation of the screw 4 can make the two sliders 3 move closer to each other, so that the heat-fused end of the pipe can be inserted into the inside of the sleeve. After the heat fusion welding is completed, loosen the clamping screw 11 and disassemble the fixture.
