Description

Technical Field

[0001] This utility model relates to the field of pipe installation, specifically to an auxiliary docking component for plumbing pipe installation. Background Technology

[0002] Most plumbing pipes are made of plastic. Each section of pipe is joined together at the ends using connectors, reducers, tees, crosses, etc. Generally, the inner diameter of the connecting sleeve is larger than the inner diameter of the pipe, but slightly smaller than its outer diameter. Before the pipe is inserted into the connecting sleeve, the end is preheated with a heat gun to melt it slightly. After it cools and reshapes, it adheres to the inner wall of the connecting sleeve, effectively fixing the pipe and achieving a pipe seal.

[0003] During the cooling process, the water pipe is often held by hand for a long time. When splicing after heat fusion, the water pipe is also squeezed into the connecting sleeve by hand. In these situations, it cannot be guaranteed that the pipe held by hand is always in a collinear state with the connecting mother pipe. Once tilting occurs, the tilt caused by the new pipe part cannot be corrected after the heat fusion solidifies, which will affect the installation of water and heating pipes. Either the pipes are removed and reinstalled, or the current situation of the pipe network being crooked and the quality being reduced is tolerated.

[0004] Therefore, an auxiliary docking component for installing plumbing pipes is provided. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that when inserting the heat-fused pipe end into the interface and waiting for it to cool, there is a possibility that the water pipe may become misaligned while holding it in the hand or while inserting it. This could further result in the water pipe section being crooked after the connection is completed.

[0007] Technical solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an auxiliary docking assembly for installing plumbing pipes, comprising:

[0009] A support rod and a load-bearing rod are rotatably connected to each other. The end of the support rod is provided with a clamping groove, and the end of the load-bearing rod is rotatably connected within the clamping groove. A positioning component is provided between the ends of the support rod and the load-bearing rod to enable them to be in a collinear or perpendicular state.

[0010] The support rod is equipped with a clamping mechanism for installing the component onto the main body of the water heating pipe, and the bearing rod is equipped with a limiting mechanism for connecting the spliced ​​water pipe to the main body of the water heating pipe.

[0011] Furthermore, the support rod has a screw hole, and the clamping mechanism includes a screw rod threaded into the screw hole of the support rod. A drive plate is rotatably connected to one end of the screw rod, and V-shaped clamping rods are rotatably connected to both ends of the support rod. A guide rod is rotatably connected between the center of the clamping rod and the drive plate.

[0012] Furthermore, two slide rails are sequentially installed on the end of the bearing rod away from the support rod, and clamps that limit and hold the spliced ​​water pipes are connected to both ends of the slide rails.

[0013] Furthermore, a drive block with a screw hole is connected to one side of the slide rail, and a slider is slidably connected inside the slide rail. The clamping bar includes a support shaft rotatably connected between the drive block and the slider. A roller is connected to the support shaft. The drive blocks are connected together by a common threaded screw with opposite thread structures at both ends. A handle is connected to both the end of the screw and the middle area of ​​the screw.

[0014] Furthermore, the positioning assembly includes positioning plates respectively connected above the top of the clamping groove and on one side of the top. The positioning plates are provided with through holes. The two sides of the end of the support rod are connected with spring buckles that are embedded in the through holes through spherical ends to achieve auxiliary position calibration above the support rod. The ends of the support rod and the support rod are connected together with a fixing assembly to fix the positions of the two after positioning calibration.

[0015] Furthermore, the fixing component includes studs that penetrate the end of the support rod and are connected to both sides of the end of the support rod, and nuts are threaded onto the studs. Beneficial effects

[0016] The advantages of this utility model compared with the prior art are as follows: This application provides a component for positional alignment and positioning during water pipe connection and installation. It uses two mutually rotating rods to support and install the main body of the water pipe and the splicing part, respectively. By utilizing the pre-positioned position of the rods and the subsequent restriction effect on the position of the new water pipe, the position of the new water pipe on the main pipe is positioned, thereby avoiding unstable support effect that could cause the new water pipe to deviate.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0025] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an auxiliary docking assembly for installing plumbing pipes, combined with the attached... Figure 1-2 It includes: a support rod 1 and a bearing rod 19 that are rotatably connected to each other, wherein the end of the support rod 1 is provided with a clamping groove 7, and the end of the bearing rod 19 is rotatably connected within the clamping groove 7;

[0026] The auxiliary docking assembly works by binding the support rod 1 to the part of the main pipe that will receive the new section of water pipe. The bearing rod 19, as an extension of the support rod 1, supports the new water pipe to be installed, helping to stabilize its position during the splicing process, so as to achieve the final pipe extension direction consistent with the installation port of the main pipe, that is, the axial direction of the water pipe.

[0027] Combined with appendix Figure 3-5 The support rod 1 is equipped with a clamping mechanism for installing the component on the main body of the water heating pipe. The support rod 1 has a screw hole. The clamping mechanism includes a screw rod 2 threaded into the screw hole of the support rod 1. A drive plate 4 is rotatably connected to the end of the screw rod 2. V-shaped clamping rods 5 are rotatably connected to the ends of the support rod 1. A guide rod 6 is rotatably connected between the center of the clamping rod 5 and the drive plate 4.

[0028] By rotating screw 2, the drive plate 4 moves on one side of the support rod 1. Utilizing the pushing and pulling effect of guide rod 6, guide rod 6 and clamping rod 5 are forced to rotate, changing the size of the area between the four rods. When each rod is tightly attached to the outer wall of the pipe, the thread locking effect between screw 2 and the screw hole of support rod 1 can firmly hold and fix the component on the pipe. Furthermore, the clamping rod 5 is provided at both the upper and lower ends of support rod 1, further enhancing the stability of the component after installation.

[0029] Combined with appendix Figure 3-4 and attached Figure 6 The bearing rod 19 is equipped with a limiting mechanism for connecting the spliced ​​water pipe to the main body of the water heating pipe. Two slide rails 13 are installed in sequence on the end of the bearing rod 19 away from the support rod 1. The two ends of the slide rail 13 are connected to clamping bars that limit and hold the spliced ​​water pipe. A drive block 15 with a screw hole is connected to one side of the slide rail 13. A slider 14 is slidably connected in the slide rail 13. The clamping bar includes a support shaft 16 rotatably connected between the drive block 15 and the slider 14. A roller 17 is connected to the support shaft 16. The drive blocks 15 are threaded together with a screw 18 with opposite thread structures at both ends. A handle 3 is connected to the end of the screw 12 and the middle area of ​​the screw 18.

[0030] The water pipes to be spliced ​​are placed between two rollers 17. The rollers 17 clamp the water pipes tightly by rotating the screw 18. This ensures that after the water pipe ends are inserted into the connecting pipe, tee, or cross pipe, the water pipe will hardly shift in the opposite direction while waiting for the hot melt part to cool down. This prevents the new water pipe from deviating in the direction of extension after cooling and connection.

[0031] Furthermore, by rotating screw 18, the gap between the two clamping rods can be adjusted, making it suitable for connecting water pipes of different diameters within a small range. Example

[0032] Combined with appendix Figure 5 A positioning component is provided between the ends of the support rod 1 and the bearing rod 19 to enable them to be in a collinear or perpendicular state. The positioning component includes a positioning plate 10 connected to the top of the clamping groove 7 and the top side respectively. The positioning plate 10 is provided with a through hole 11. The bearing rod 19 is provided with spring buckles 12 on both sides of its end, which are inserted into the through hole 11 through a spherical end to achieve auxiliary position calibration above the support rod 1. A fixing component is provided between the ends of the support rod 1 and the bearing rod 19 to fix their positions after positioning calibration. The fixing component includes studs 8 connected to both sides of the end of the bearing rod 19 and penetrating the end of the support rod 1. Nuts 9 are threadedly connected to the studs 8.

[0033] The tilt angle of the bearing rod 19 on the support rod 1 is also a factor affecting whether the position is qualified after the two parts of the water pipe are connected. Since the water pipes are almost at an angle of 90 degrees or 180 degrees to each other when connected, a positioning plate 10 with a through hole 11 is welded on the top of the support rod 1 and on the top side. The lines extending from the center of the two through holes 11 are perpendicular to each other after the support rod 1 and the bearing rod 19 intersect at the point where they rotate relative to each other.

[0034] Then, drill a countersunk hole at the position of the bearing rod 19 corresponding to the through hole 11, and install a spring clip 12 with a ball-shaped end in the countersunk hole. When the bearing rod 19 rotates, the spring clip 12 is just embedded in the through hole 11, indicating that the bearing rod 19 and the support rod 1 are in a collinear or perpendicular state, so that the water pipe can be connected and assembled in the same direction.

[0035] The spring clip 12 and the positioning plate 10 are mainly used to locate the relative positions of the support rod 1 and the bearing rod 19. Their fixing effect is not strong. Therefore, at the position where the support rod 1 and the bearing rod 19 are rotatably connected, two sets of bolts and nuts 9 are added to fix them. The nuts 9 located on both sides of the support rod 1 are fed in a rotating manner along the thread of the stud 8 to tightly clamp the support rod 1 and the bearing rod 19, thereby fixing them and preventing them from rotating.

[0036] In practical implementation, when using this device for auxiliary installation during water pipe splicing, first place the support rod 1 roughly on one side of the main pipe receiving end. Then rotate the screw 2, and the clamping rods 5 slowly move closer to each other towards the center of the support rod 1, cooperating with the guide rod 6 to finally clamp this part of the main pipe. Since there are clamping rod assemblies at both ends of the support rod 1, even if the support rod 1 is not horizontal with the main water pipe before installation, it can be forced to remain horizontal with the main water pipe after final tightening. Secondly, the position of the bearing rod 19 on the support rod 1 is determined by the position of the new water pipe to be assembled on the main water pipe. If the two parts of the water pipe are installed in a collinear manner, it is recommended that the support rod 1 be installed below the main water pipe. If it is installed vertically, then... The support rod 1 needs to be installed on one side of the main water pipe. When the bearing rod 19 rotates towards the target position, it can be stopped when the spring clip 12 is found to be embedded in the through hole 11. Place the new section of water pipe on the bearing plate. Its spliced ​​end is heated and softened and inserted into the connecting sleeve such as the tee pipe. The clamps on both sides are tightly attached to the two sides of the new water pipe under the rotation of the screw 18. When inserting, or when holding it and applying force towards the connecting sleeve to increase the fixing effect, the rotating roller 17 on the clamp will not restrict its axial movement and will also prevent it from deflecting in other directions when the person applies force. After the necessary waiting time, the water pipes are connected to each other. The auxiliary connection component can be removed from the pipe by reversing the operation.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
