Description

Technical Field

[0001] This invention relates to the field of pipe fasteners, and in particular to a connector that performs multiple connection functions and its method of use. Background Technology

[0002] During the installation of water supply and heating pipes, welding is often used to connect two sets of pipes. However, when working in confined spaces, the limited space restricts the movement of the welding torch, making it inconvenient for workers to operate and easily leading to weak weld joints and water leaks. To address these issues, we propose a connector that achieves multiple connection functions and its usage method. Summary of the Invention

[0003] The main objective of this invention is to provide a connector that realizes multiple connection functions and its usage method, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A connector that performs multiple connection functions includes an end assembly, at least one set of sheath assemblies, a peanut-shaped section assembly, and a connecting pipe. Two adjacent sheath assemblies are connected by the peanut-shaped section assembly, and the sheath assemblies are rotatable about the rotation axis of the peanut-shaped section assembly. The connecting pipe is installed through the sheath assemblies and the peanut-shaped section assembly. The end assembly is installed on the outer side of the end of the connecting pipe, and the other end of the end assembly is connected to the pipe.

[0006] Furthermore, the end assembly includes a clamp, a sleeve, and a fixing tube. The fixing tube is installed on the outside of the connecting tube, the sleeve is installed on the outside of the fixing tube, and the other end of the sleeve is connected to the clamp via a thread.

[0007] Furthermore, the sheath assembly includes symmetrically distributed shells connected by bolts. A semi-circular tube groove is provided in the middle of the shell, and a rotating segment cavity is provided at its end. Symmetrically distributed arc-shaped locking and toothed rings are provided inside the rotating segment cavity.

[0008] Furthermore, the peanut section assembly includes a main body, a through hole in the middle of the main body, semi-circular engaging portions symmetrically arranged at both ends of the main body, and teeth that cooperate with engaging tooth rings on the outer end face of the engaging portions.

[0009] Furthermore, a connecting pin is symmetrically arranged inside one end face of the main body, and the other end of the connecting pin passes through the housing and is connected to a connecting seat. An adjusting rod is threadedly connected to the middle of the connecting seat.

[0010] Furthermore, a rotating pin is symmetrically arranged inside the other end face of the main body, the rotating pin penetrates the housing, and a spring plate is arranged on the outside of the rotating pin, with the two ends of the spring plate connected to the housing and the main body respectively.

[0011] Furthermore, the cross-section of the end face where the clamp head connects to the sleeve is trapezoidal, and the clamp head includes a rotating part and a snap-fit ​​part. The snap-fit ​​part has a multi-piece radial structure and is evenly distributed at one end of the rotating part.

[0012] The present invention has the following beneficial effects:

[0013] (1) Compared with the prior art, the connector structure proposed in this invention uses end components and connecting pipes to connect the pipes to be connected. By determining the spatial position of the pipe openings on both sides, the pipe connection path in the space is planned, the path length of the planned pipe connection path is calculated, and the number of sheath components and peanut components used is determined according to the path length calculation result. They are then assembled and connected in sequence. The tilt angle of the connection node between each sheath component and peanut component is adjusted according to the planned pipe connection route so that the pipe centerline of the connecting pipe coincides with the pipe connection path. There is no need to weld the pipes to be connected, and it can be operated in a narrow space.

[0014] (2) Compared with the prior art, the connector structure proposed in this invention, when it is necessary to bend the pipe to be connected, marks the bending position of the pipe to be connected, uses a set of peanut joint components to connect two sets of sheath joint components, then puts the assembled peanut joint components and sheath joint components on the outside of the pipe to be connected, and slides the mechanism so that the middle position of the main body of the peanut joint component coincides with the marked bending position, rotates the adjusting rod so that the toothed part of the outer end face of the engaging part disengages from the engaging tooth ring inside the rotating cavity of the housing, and rotates the housing on both sides until the pipe to be connected is bent to the required angle;

[0015] (3) Compared with the prior art, the connector structure proposed in this invention can fix and isolate the pipe by sleeved the assembled peanut joint assembly and sheath assembly on the outside of the pipe to be connected, thus playing a certain protective role.

[0016] (4) Compared with the prior art, the connector structure proposed in this invention has the connecting pipe surrounded inside the peanut joint assembly and sheath assembly during use. When the pressure inside the pipe increases, the connecting pipe can be protected, which can prevent the pipe from rupturing under high pressure. Attached Figure Description

The connecting pipe 4 is installed through the sheath assemblies 2 and the peanut-shaped assembly 3.

[0038] The end assembly 1 includes a clamp 101, a sleeve 102, and a fixing tube 103. The fixing tube 103 is installed on the outside of the connecting tube 4, and the sleeve 102 is installed on the outside of the fixing tube 103. The other end of the sleeve 102 is connected to the clamp 101 by a thread.

[0039] The sheath assembly 2 includes symmetrically distributed housings 201, which are connected by bolts. A semi-circular tube groove 202 is provided in the middle of the housing 201, and a rotating joint cavity 203 is provided at its end.

[0040] The peanut section component 3 includes a main body 301, with a through hole in the middle of the main body 301. Semi-circular engaging parts 302 are symmetrically arranged at both ends of the main body 301. Teeth 303 that cooperate with the engaging tooth ring 204 are arranged on the outer end face of the engaging parts 302.

[0041] A connecting pin 5 is symmetrically arranged inside one end face of the main body 301. The other end of the connecting pin 5 passes through the housing 201 and is connected to a connecting seat 6. An adjusting rod 7 is threadedly connected to the middle of the connecting seat 6.

[0044] The method of using the connector includes the following steps:

[0045] Step 1: Determine the spatial location of the pipe openings to be connected on both sides, plan the pipe connection path within the space, and calculate the path length of the planned pipe connection path;

[0046] Step 2: Based on the path length calculation result of the pipeline connection path, determine the number n of sheath assembly 2 to be used, and determine the number n-1 of peanut assembly 3 to be used based on the number of sheath assembly 2. It should be noted that the effective length of sheath assembly 2 and peanut assembly 3 should be greater than the path length of the pipeline connection path.

[0047] Step 3: Connect one end assembly 1 to the pipe to be connected. First, insert the pipe to be connected into the clamp 101 of the end assembly 1, so that the end face of the pipe to be connected is close to the inner end face of the sleeve 102. Rotate the sleeve 102. Under the squeezing action of the inner arc end face of the sleeve 102, the multiple clamping parts 01b of the clamp 101 retract inward at the same time, clamping and fixing the end of the pipe to be connected. After the end assembly 1 is connected and fixed to the pipe to be connected, assemble the sheath assembly 2 and the peanut assembly 3 in sequence.

[0048] Step four: Adjust the tilt angle of each sheath section assembly 2 and peanut section assembly 3 connection node according to the planned pipeline connection route, such as... Figure 6 , Figure 7 and Figure 9 As shown in the usage status, make the centerline of the connecting pipe 4 coincide with the pipe connection path;

[0049] Step 5: Connect and fix the other end assembly 1 to the pipe to be connected at the other end. After fixing, rotate the adjusting rod 7 to make the toothed part 303 on the outer end face of the engaging part 302 engage with the engaging toothed ring 204 inside the rotating cavity 203 of the housing 201, so that the sheath assembly 2 and the peanut assembly 3 are fixed in position.

[0058] By adopting the above technical solution: when it is necessary to bend the pipe to be connected, firstly, mark the bending position of the pipe to be connected, use a set of peanut joint components 3 to connect two sets of sheath components 2, then put the assembled peanut joint components 3 and sheath components 2 on the outside of the pipe to be connected, and slide the mechanism so that the middle position of the main body 301 of the peanut joint component 3 coincides with the marked bending position.
