[0002] Composite materials are composed of two or more materials with different properties, which are formed into materials with new properties on a macro scale through physical or chemical methods. Various materials complement each other in performance and produce synergistic effects, so that the comprehensive performance of composite materials is better than that of the original component materials and meets various requirements. In composite materials, ultrasonic testing, also called ultrasonic testing, is the use of ultrasonic technology for testing. It is one of the five conventional non-destructive testing methods. When non-destructive testing of composite materials is carried out, ultrasonic testing is required. When testing composite pipes, the composite pipes need to be fixed by testing tools;

The second threaded rod, the second threaded sleeve, and the clamping plate can be used to cooperate. Similarly, the second threaded rod can be rotated to adjust the distance between the two clamping plates to adjust and fix the two ends of materials of different sizes respectively, so as to avoid the material shaking or falling during the test, which affects the normal progress of the test.

The inner sides of the two groups of slide grooves 11 are slidably connected with the slider 9, and one side of the two groups of sliders 9 is provided with an inner splint 10. The shape of the inner splint 10 is arc-shaped, and a rubber pad is provided on the outer side of the inner splint 10 to increase the contact area with the composite pipe. The buffer pad can buffer the clamping damage to the movable plate 5 to prevent the detection material from being damaged. Two groups of hinged rods 12 are hinged in the middle of one side of the movable plate 5, and one side of the two groups of hinged rods 12 are respectively hinged to the two groups of sliders 9, and a discharge assembly is provided in the middle of the top end of the base 1.

[0026] Furthermore, the discharge assembly includes a discharge plate 15, a rotating rod 16, a rotating block 17, a slot 18, a sleeve 19, a spring B20, an insertion rod 21 and a fixed plate 14. The fixed plate 14 is arranged in the middle of one end of the top of the base 1, and the rotating rod 16 is sleeved in the middle of one end of the top of the base 1 near the fixed plate 14. The discharge plate 15 is arranged on the top of the rotating rod 16, and a rotating block 17 is arranged in the middle of the outer side of the rotating rod 16.

At this time, the four groups of inner clamping plates 10 can be inserted into the inner side of the two groups of the composite pipe, and then the two groups of side clamping plates 8 can be clamped on both sides of the composite pipe. When the two groups of movable plates 5 overcome the elastic force of the spring A7 and approach each other, the two groups of sliders 9 can be driven to move away from each other through the connection of the hinged rod 12, so that the two groups of inner clamping plates 10 can move away from each other and clamp the composite pipe from the inside. At this time, the spring A7 in a compressed state can push the two groups of side clamping plates 8 to clamp the composite pipe from both sides through its elastic force, which can improve the clamping stability of the device and prevent the pipe from moving during ultrasonic non-destructive testing;

[0031] After the composite pipe is fixed and tested, the unloading plate 15 can be rotated and reset again to reduce the space occupied by it.
