[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a strength testing device for plastic pipe handles, comprising: a support box 1; a hydraulic cylinder 3 positioned above the support box 1, with a lifting rod 4 fixedly connected to the output end of the hydraulic cylinder 3, a pressure plate 12 provided at the bottom of the lifting rod 4, and a pressure sensor 8 and a pressure sensor 11 provided between the pressure plate 12 and the lifting rod 4 for detecting the compressive and tensile strength of the plastic pipe handle; a clamping mechanism positioned below the pressure plate 12, the clamping mechanism comprising a movable slide 16 slidably disposed on the top of the support box 1, a movable slide 17 adjustablely mounted on the top of the movable slide 16, a clamping part provided on the top of the movable slide 17, the clamping part comprising a movable clamping plate 19 movably disposed on the top of the movable slide 17, and a support plate 5 fixedly connected to the top of the movable clamping plate 19 for supporting the workpiece.

[0024] It should be noted that this utility model includes an operation panel, controller, processor, and display. During testing, one end of the plastic pipe handle to be tested is clamped in the middle of the clamping part. Then, the hydraulic cylinder 3 and the pressure plate 12 drive the limiting fork 14 to apply downward pressure to the plastic pipe handle. The pressure value is observed when the plastic pipe handle breaks. The position of the clamping part is adjusted by moving the sliding table 16 so that the limiting fork 14 can apply pressure to different positions of the plastic pipe handle to test its strength performance at different stress positions. The plastic pipe handle is clamped after adjusting the tilt angle, and pressure is applied to it at different positions at different angles by the limiting fork 14. The support plate 5 can also be adjusted to the end of the sliding table 17 so that the bottom of the sliding table 17 is supported from the bottom of the support plate 5. Then, the plastic pipe handle is placed vertically along the length and width directions to test its strength in the horizontal position.

[0025] See also Figure 5 As shown, a support frame 2 is fixedly connected to the top of the support box 1. The hydraulic cylinder 3 is fixed to one side of the top of the support frame 2. An upper connecting plate 7 is fixedly connected to the end of the lifting rod 4. A metal ring is connected to the outside of the upper connecting plate 7 through a limiting rod 9. A pressure sensor 11 is installed between the metal ring and the upper connecting plate 7. A spring 10 is sleeved on the outside of the limiting rod 9 and between the metal ring and the upper connecting plate 7. A lower connecting plate 6 is fixedly connected to the bottom of the limiting rod 9. A pressure sensor 8 is fixedly connected to the lower connecting plate 6.

[0026] It should be noted that when the hydraulic cylinder 3 drives the pressure plate 12 downward through the lifting rod 4, the lifting rod 4 drives the upper connecting plate 7 to apply pressure to the pressure sensor 8 at the top of the lower connecting plate 6, and observes the maximum value of the pressure sensor 8. When the hydraulic cylinder 3 and the lifting rod 4 drive the pressure plate 12 to rise and pull the plastic pipe handle upward to test its tensile performance, the upper connecting plate 7 presses the pressure sensor 11 at the bottom of the metal ring upward to test its tensile strength.

[0027] See also Figure 3 As shown, one end of the pressure plate 12 is fixedly connected to a connecting rod 13 for installing a plastic pipe handle, and the other end of the pressure plate 12 is detachably installed with a limit fork 14 by bolts.

[0028] It should be noted that when testing the tensile strength of this utility model, one end of the plastic pipe handle is sleeved on the outside of the connecting rod 13, and limited by the nut on the outside of the connecting rod 13. Then, the other end of the plastic pipe handle is fixed by the clamping part. The hydraulic cylinder 3 and the lifting rod 4 drive the pressure plate 12 to pull the plastic pipe handle to test its tensile strength. The limiting fork 14 is opened on the outside of the plastic pipe handle. The pressure plate 12 drives the limiting fork 14 to press down and apply pressure to the plastic pipe handle. When the pressure plate 12 presses the plastic pipe handle horizontally, the limiting fork 14 is removed by bolts.

[0029] See also Figure 2 , 4 As shown, the clamping mechanism also includes a guide rail 15 fixed to the top of the support box 1, a movable slide 16 slidably mounted on the top of the guide rail 15, a bolt for limiting the position of the movable slide 16 threadedly connected to one side of the movable slide 16, both the movable slide 16 and the movable slide 17 are L-shaped structures, an adjusting screw 21 is threadedly connected to one end of the movable slide 16, one end of the adjusting screw 21 is rotatably connected to the movable slide 17, the clamping part also includes a fixing plate 18 fixed to the end of the movable slide 17, an adjusting screw 20 is threadedly connected to one end of the movable slide 17, and the end of the adjusting screw 20 is rotatably connected to the movable plate 19.

[0030] It should be noted that in this invention, the movable slide 16 slides on the outside of the guide rail 15 to adjust the position of the clamping plate 12. The position of the movable slide 16 is fixed by the bolts on the outside of the movable slide 16 pressing against the guide rail 15. The position of the movable slide 17 at the top of the movable slide 16 is adjusted by rotating the adjusting screw 21, so that the movable slide 17 moves along the Y-axis at the top of the movable slide 16. The fixed clamping plate 18 has an angle line on its outside, which can be used to adjust the plastic pipe handle. The tilt angle during clamping is determined, and the adjusting screw 21 is rotated to adjust the moving clamp 19 to move along the moving slide 17 towards the fixed clamp 18, thereby clamping the plastic pipe handle. When the moving clamp 19 moves away from the fixed clamp 18, the support plate 5 cooperates with the top of the moving slide 17, so that the moving slide 17 supports the bottom of the support plate 5. The plastic pipe handle is placed on the top of the support plate 5, and the pressure plate 12 applies horizontal pressure to it, thereby strengthening its strength when placed horizontally.
