[0002] Currently, pipes are essential materials for construction projects. Commonly used pipes include water supply pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, and rainwater pipes. With the development of science and technology, the pipes used in home decoration have also gone through the development process of ordinary cast iron pipes → cement pipes → (reinforced concrete pipes, asbestos cement pipes) → ductile iron pipes, galvanized steel pipes → plastic pipes and aluminum-plastic composite pipes.
[0003] Among them, pipe tensile testing is an important means of evaluating the mechanical properties of pipes. It mainly includes the determination of indicators such as tensile strength, yield strength, and elongation. The test items are: pipe tensile testing mainly measures yield strength, tensile strength, elongation after fracture, etc. These indicators reflect the mechanical properties and plastic deformation capacity of pipes during the tensile process.
[0004] For pipe stretching, fixing both ends of the pipe is particularly important. The conventional fixing method is to clamp the outer wall of the pipe with a clamping mechanism. This fixing method has limited clamping force and is prone to loosening during tensile testing. Therefore, a new technical solution needs to be designed to solve this problem. The stability of the pipe during testing can be ensured by clamping the inner and outer sides of the pipe. Utility Model Content
[0005] The purpose of this utility model is to provide a testing and fixing device for building construction pipes, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a building construction pipe material testing and fixing device, comprising a base, a fixing frame slidably installed on one side of the top of the base, an outer fixing ring fixedly installed in the middle of the fixing frame, an inner fixing ring fixedly installed on one side of the outer fixing ring, an adjusting cylinder movably installed inside the inner fixing ring, and an inner clamping mechanism installed at one end of the adjusting cylinder.
[0007] The internal clamping mechanism includes a positioning groove opened on one side inside the adjusting cylinder, a first screw hole opened on one side of the positioning groove, a first screw threaded in the first screw hole, a pressing block rotatably installed at one end of the first screw, piston grooves opened on both sides of the positioning groove, wedge blocks movably installed in both sets of piston grooves, and inner support rings fixedly installed on the outer walls of both sets of wedge blocks.

[0011] As an optional solution to the technical solution of this application, a second screw hole is provided on both sides of the outer fixing ring, and a second screw is threaded into each of the two sets of second screw holes, which can push the outer support ring to move.
[0012] As an optional solution to the technical solution of this application, an outer support ring is rotatably installed on the inner side of each of the two sets of second screws. The two sets of outer support rings correspond to the two sides of the outer wall of the pipe, which can clamp the outer wall of the pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The technical solution of this application pushes the adjusting cylinder inside the inner fixing ring so that the inner side of the adjusting cylinder is inserted into the inner wall of the pipe. The first screw in the tightening mechanism can push the extrusion block in the positioning groove to move horizontally. After the side wall of the extrusion block is in contact with the wedge blocks in the two sets of piston grooves, as the extrusion block moves continuously, it can continuously squeeze the two sets of wedge blocks outward, and squeeze the inner support ring on the outside of the two sets of wedge blocks to the inner wall of the pipe, supporting the inner wall of the pipe and ensuring that the adjusting cylinder can clamp the inner wall of the pipe, which greatly increases the stability and firmness of the pipe during tensile testing.

The technical solution of this application has springs sleeved on the outer walls of two sets of wedge blocks, and each set of springs is fixedly installed on both sides of the wedge block and the piston groove side wall. When the operator rotates the second screw in the second screw hole in the opposite direction, the extrusion block can be moved in the opposite direction. After the moving block moves away from the two sets of wedge blocks, the wedge block can be reset to the piston groove by the supporting force of the spring sleeved on the outer wall of the wedge block, so that the adjusting cylinder can clamp the inner wall of different pipes again.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a building construction pipe material testing and fixing device, including a base 1, a fixing frame 11 slidably installed on one side of the top of the base 1, an outer fixing ring 12 fixedly installed in the middle of the fixing frame 11, an inner fixing ring 13 fixedly installed on one side of the outer fixing ring 12, an adjusting cylinder 14 movably installed inside the inner fixing ring 13, and an inner clamping mechanism installed at one end of the adjusting cylinder 14.
[0021] The internal clamping mechanism includes a positioning groove 2 opened on one side inside the adjusting cylinder 14, a first screw hole 21 connected to one side of the positioning groove 2, a first screw 22 threaded in the first screw hole 21, a pressing block 23 rotatably installed at one end of the first screw 22, piston grooves 24 connected to both sides of the positioning groove 2, wedge blocks 25 movably installed in both sets of piston grooves 24, and inner support rings 26 fixedly installed on the outer walls of both sets of wedge blocks 25. The two sets of inner support rings 26 correspond to the inner walls of the pipe, and the two sets of wedge blocks 25 correspond to both sides of the pressing block 23. The cross-section of the pressing block 23 is trapezoidal.
[0022] In this technical solution, by pushing the inner adjusting cylinder 14 inside the inner fixing ring 13, the inner side of the adjusting cylinder 14 is inserted into the inner wall of the pipe. When the first screw 22 in the tightening mechanism is engaged, the extrusion block 23 in the positioning groove 2 can be pushed to move horizontally. After the side wall of the extrusion block 23 is in contact with the wedge blocks 25 in the two sets of piston grooves 24, as the extrusion block 23 moves continuously, the two sets of wedge blocks 25 can be continuously squeezed outward, and the inner support ring 26 on the outside of the two sets of wedge blocks 25 can be squeezed to the inner wall of the pipe to support the inner wall of the pipe. This ensures that the adjusting cylinder 14 can clamp the inner wall of the pipe, greatly increasing the stability and firmness of the pipe during tensile testing.
[0023] In some technical solutions, springs 3 are sleeved on the outer walls of both sets of wedge blocks 25. Each set of springs 3 is fixedly installed on the side walls of the wedge block 25 and the piston groove 24, respectively, which can support the wedge block 25.
[0024] In this technical solution, when the operator rotates the second screw 32 in the second screw hole 31 in the opposite direction, the extrusion block 23 can be moved in the opposite direction. After the moving block moves away from the two sets of wedge blocks 25, the wedge block 25 can be reset to the inside of the piston groove 24 by the supporting force of the spring 3 sleeved on the outer wall of the wedge block 25, so that the adjusting cylinder 14 can clamp the inner wall of different pipes again.
[0025] In some technical solutions, the outer fixing ring 12 has a second screw hole 31 on both sides, and a second screw 32 is threaded in both sets of second screw holes 31, which can push the outer support ring 33 to move. The outer support ring 33 is rotatably installed on the inner side of both sets of second screws 32. The two sets of outer support rings 33 correspond to the two sides of the outer wall of the pipe, which can clamp the outer wall of the pipe.
[0026] In this technical solution, the pipe to be subjected to tensile testing is placed on the base 1, and the two ends of the pipe are respectively aligned with two sets of fixing brackets 11. The operator can first insert the two ends of the pipe into the inner side of the outer fixing ring 12, and then tighten the second screw 32 in the second screw hole 31 to squeeze the multiple sets of outer support rings 33. After the outer support rings 33 are firmly attached to the outer wall of the pipe, the outer fixing ring 12 can clamp the outer wall of the pipe.
[0027] In some technical solutions, limiting grooves are opened on both sides of the positioning groove 2, and limiting blocks are slidably installed in both sets of limiting grooves. The side walls of the two sets of limiting blocks are fixedly installed on both sides of the extrusion block 23, which can limit the extrusion block 23.
[0028] In this technical solution, when the first screw 22 inside the inner clamping mechanism is tightened, the limiting slider inside the limiting groove can be used to push the extrusion block 23 inside the positioning groove 2 to move horizontally.
[0029] When using a building construction pipe material testing and fixing device, it should be noted that this utility model is a building construction pipe material testing and fixing device, and each component is a general standard part or a part known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0030] In use, first place the pipe to be tested on the base 1, and align both ends of the pipe with the two sets of fixing brackets 11. The operator can first insert both ends of the pipe into the inner side of the outer fixing ring 12, and tighten the second screw 32 in the second screw hole 31 to compress the multiple sets of outer support rings 33. After the outer support rings 33 are firmly attached to the outer wall of the pipe, the outer fixing ring 12 can clamp the outer wall of the pipe. At the same time, push the adjusting cylinder 14 in the inner fixing ring 13 so that the inner side of the adjusting cylinder 14 is inserted into the inner wall of the pipe. Tighten the first screw 22 in the inner clamping mechanism to push the extrusion block 23 in the positioning groove 2 to move horizontally. After the side wall of the extrusion block 23 is attached to the wedge block 25 in the two sets of piston grooves 24, as the extrusion block 23 continues to move, The two sets of wedge blocks 25 can be continuously pressed outwards, and the inner support rings 26 on the outer sides of the two sets of wedge blocks 25 can be pressed against the inner wall of the pipe, supporting the inner wall of the pipe and ensuring that the adjusting cylinder 14 can clamp the inner wall of the pipe, greatly increasing the stability and firmness of the pipe during tensile testing. At the same time, springs 3 are sleeved on the outer walls of the two sets of wedge blocks 25, and each set of springs 3 is fixedly installed on the side walls of the wedge blocks 25 and the piston groove 24 respectively. When the operator rotates the second screw 32 in the second screw hole 31 in the opposite direction, the pressing block 23 can be pushed to move in the opposite direction. After the moving block moves away from the two sets of wedge blocks 25, with the support force of the springs 3 sleeved on the outer walls of the wedge blocks 25, the wedge blocks 25 can be reset to the inside of the piston groove 24, making it easy for the adjusting cylinder 14 to clamp the inner wall of different pipes again.
