[0002] Tensile testing is to measure the changes in the mechanical properties of materials during the tensile process by applying an axial tensile load to the specimen. During the tensile test, key indicators such as the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, and yield strength of the specimen can be obtained. These indicators are of great significance for evaluating the quality and reliability of materials and optimizing product design.

[0003] During the tensile test, a medium is required to connect the tensile tester and the material to be tested. In the prior art, ropes are often used for connection. The rope is used to measure the tension of the hook. This measurement mode has two disadvantages:

[0005] 2. It is difficult to operate during the measurement process and the rope will easily fall off.

[0006] In order to solve the above problems, a new type of contoured hook tension test fixture is proposed to replace the rope for tension test. Utility Model Content

It solves the problem that the prior art mostly uses ropes for connection. The use of ropes reduces the actual tension of the hook when conducting tension tests across the line, is difficult to operate during the measurement process, and the rope is easy to fall off.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 In this embodiment, a profile hook tension gauge comprises a pull plate 1, a hanging hole 2 is provided on the front of the pull plate 1, a fastening mechanism 3 is provided inside the hanging hole 2, a connecting plate 4 is plugged into the bottom of the pull plate 1, a supporting plate 5 is fixedly installed at the bottom of the connecting plate 4, a connecting groove 6 is provided at the bottom end of the pull plate 1 and the top of the supporting plate 5, connecting blocks 7 are fixedly installed at the bottom of the left and right sides of the pull plate 1 and the left and right sides of the supporting plate 5, and a bolt 8 is threadedly connected between the two connecting blocks 7;

[0025] The fastening mechanism 3 includes a support rod 301, the support rod 301 is fixedly installed on the inner wall of the hanging hole 2, the outer surface of the support rod 301 is sleeved with two sliding sleeves 302, and a retracting rod 303 is rotatably installed on the two sliding sleeves 302. An extrusion block 304 is movably installed between the two retracting rods 303, and the outer surface of the support rod 301 is sleeved with a support spring 305.

[0026] In this embodiment, a hanging hole 2 for connecting a tensile force detector is provided above the surface of the pull plate 1, and the connecting plate 4 is inserted into the interior of the pull plate 1 and can be extended and retracted at the bottom of the pull plate 1. The main body of the pull plate 1 is made of No. 45 steel plate to ensure its strength.

[0027] In this embodiment, the connecting groove 6 on the pull plate 1 and the connecting groove 6 on the support plate 5 are spliced ​​together to form a U-shaped groove, which is used to clamp the object to be tested inside the U-shaped groove for tension detection. The distance between the pull plate 1 and the support plate 5 is adjusted by a bolt 8, and the bolt 8 connects the connecting blocks 7 on both sides. Turning the bolt 8 clockwise can reduce the distance between the two connecting blocks 7, and turning the bolt 8 counterclockwise can expand the distance between the two connecting blocks 7, thereby increasing the size of the U-shaped groove to adapt to different objects to be tested and improving the stability of the installation.

[0028] In this embodiment, a mounting frame is fixedly installed on the inner wall of the mounting groove, and the support rod 301 is fixedly installed inside the mounting frame. The ends of the two retractable rods 303 away from the sliding sleeve 302 are both slidably connected to the extrusion block 304, and the extrusion block 304 is provided with a slot adapted to the retractable rod 303. The two ends of the support spring 305 are respectively fixedly connected to the two sliding sleeves 302, and the two retractable rods 303 are cross-connected. When the tension tester is connected to the pulling plate 1, the test end of the tension tester is hung inside the hanging hole 2 and locked by the internal fastening mechanism 3. The fastening structure uses the support spring 305 to drive the movement of the extrusion block 304 to form an extrusion force, thereby achieving a fastening effect.

[0029] By adopting the above technical scheme, the rope used in the traditional hook tension test is replaced with a pull plate 1 made of No. 45 steel plate. When the hook tension test is performed, the two ends of the pull plate 1 are connected to the tension tester and the object to be tested. The steel plate will not be deformed due to the tension side, and the rope will not be used to perform tension test on the opposite side of the line, which will reduce the actual tension of the hook and cause inaccurate measurement data. The accuracy of the hook tension test is improved. At the same time, the use of a contoured hook tension gauge is convenient and quick to install, and both ends of the installation involve a locking structure to ensure the stability of the installation. It is not easy to fall off during the test, which improves the stability of the contoured hook tension gauge and makes it more convenient for staff to perform hook tension tests. This solves the problem that the existing technology often uses ropes for connection, and the use of ropes is used to perform tension test on the opposite side of the line, so the actual tension of the hook will be reduced, and it is difficult to operate during the measurement process, and the rope will easily fall off.
