[0019] See appendix Figure 1-4 As shown, the impact surface outer frame 1 includes a square outer frame 101 for storing a square impact material plate; and a C-shaped frame 102 rotatably installed in a through hole on one side of the square outer frame 101, the middle part of which is embedded in a groove in the middle of the square outer frame 101 for lifting and replacing the square impact material plate.

[0020] A handle is welded and fixed to the front end of the C-shaped frame 102.

[0021] Specifically, the square outer frame 101 serves as the basic frame for the impact surface and is mainly used to house the square impact material plate, providing an impact contact surface for plastic pipes and fittings when dropped. The square impact material plate can be made of steel plate or cement board. The C-shaped frame 102 is rotatably mounted in a through hole on one side of the square outer frame 101, with its center embedded in a groove in the middle of the square outer frame 101. A handle welded to its front end allows the operator to lift it up, thereby lifting the square impact material plate for easy replacement with impact material plates of different materials.

[0022] See appendix Figure 1-5 As shown, the lifting frame 2 includes a guide rail column 201 welded to the middle of the rear surface of the square outer frame 101; a screw 202 whose lower end is locked in the through hole of the base of the guide rail column 201, and the screw 202 can rotate within the through hole of the base of the guide rail column 201; a reduction motor 203 bonded and fixed inside the circular frame of the guide rail column 201, the rotating end of the reduction motor 203 being welded to the upper end of the screw 202 and driving the screw 202 to rotate; a lifting frame 204 slidably sleeved on the guide rail column 201, the upper end of the screw 202 passing through the threaded through hole of the lifting frame 204, and a C-shaped locking block inside the lifting frame 204 being engaged in the sliding groove on the side of the guide rail column 201; and a first dual-axis cylinder 205 welded to the rear surface of the lifting frame 204, the output end of the first dual-axis cylinder 205 being inserted into the limiting groove at the upper end of the guide rail column 201.

[0023] Specifically, the guide rail column 201 is welded to the middle of the rear surface of the square outer frame 101 to provide a guide rail for the lifting of the lifting frame 204. It has a sliding groove on its side to increase stability in conjunction with the C-shaped locking block of the lifting frame 204. It has a limiting groove at the top to cooperate with the output end of the first dual-axis cylinder 205 to fix the position of the lifting frame 204. The lower end of the screw 202 is inserted into the through hole of the base of the guide column 201 and can rotate. The upper end is welded to the rotating end of the geared motor 203, and the lifting frame 204 is lifted by rotating. The geared motor 203 is bonded and fixed inside the circular frame of the guide rail column 201 as a power source. Its rotating end drives the screw 202 to rotate, thereby controlling the lifting height of the lifting frame 204 and realizing the adjustment of the drop height of the plastic pipe or fitting. The lifting frame 204 can be slidably sleeved on the guide rail column 201. The internal threaded through hole cooperates with the screw 202. The C-shaped card is embedded in the slide groove of the guide rail column 201. It is used to install the angle adjuster 3, the controller 4 and the first dual-axis cylinder 205, and rotates with the screw 202 to achieve lifting. The No. 1 dual-axis cylinder 205 is welded to the rear surface of the lifting frame 204. Its output end can be inserted into the limiting groove of the guide rail column 201. By retracting or extending, the lifting frame 204 can be fixed or released, ensuring that the lifting frame 204 stays stably at the specified height.

[0024] See appendix Figure 1-9 As shown, the angle adjuster 3 includes an inner groove ring 301 welded to the front end of the lifting frame 204; an inner insert block 302 rotatably installed in the inner groove ring 301; a toothed block 303 slidably installed at both ends of the limiting through hole of the inner insert block 302, the tip of the toothed block 303 being engaged in the groove in the inner groove ring 301; and a telescopic spring 304 welded between the toothed blocks 303 to provide elastic thrust for the toothed blocks 303.

[0025] Multiple slots are evenly distributed on the inner side of the inner slot ring 301.

[0026] Specifically, the inner slot ring 301 is welded to the front end of the lifting frame 204, and multiple slots are evenly distributed on the inner side for cooperating with the tooth block 303 to achieve the positioning of the slot holder 5 at the tilt angle. The embedded block 302 is rotatably installed inside the inner slot ring 301, and its front end is connected to the slot holder 5, serving as the rotating body for angle adjustment; The toothed block 303 can be slidably installed at both ends of the limiting through hole of the inner insert block 302. The tip can be inserted into the slot of the inner slot ring 301. Under the thrust of the telescopic spring 304, the rotation angle of the inner insert block 302 is fixed, and the tilt angle of the slot holder 5 is limited. The telescopic spring 304 is welded between the two toothed blocks 303 to provide elastic thrust, ensuring that the toothed blocks 303 are stably locked in the groove of the inner groove ring 301, and maintaining the angle of the groove holder 5 unchanged when there is no external force.

[0027] See appendix Figure 1-8 As shown, the slot holder 5 includes a cylinder outer frame 501 welded to the front end of the inner block 302; a first slot clamping plate 502 welded to the front end of the cylinder outer frame 501, with three triangular plates welded and fixed to its surface; a second dual-axis cylinder 503 bonded and fixed inside the cylinder outer frame 501; six sliding rods 504 welded to the upper end of the first slot clamping plate 502; and a second slot clamping plate 505 slidably sleeved on the sliding rods 504, with three triangular plates welded and fixed to its surface; and rubber strips 506 bonded and fixed to the edges of the slots of the first slot clamping plate 502 and the second slot clamping plate 505 to increase friction.

[0028] The output end of the second dual-axis cylinder 503 is inserted into the through hole welded to the upper end of the second slot clamping plate 505, and drives the second slot clamping plate 505 to slide along the slide rod 504.

[0029] Specifically, the cylinder outer frame 501 is welded to the front end of the inner block 302 for mounting the second dual-axis cylinder 503, which is the main frame of the slot holder; The No. 1 slot clamping plate 502 is welded to the front end of the cylinder outer frame 501, and three triangular plates are welded to its surface. It cooperates with the No. 2 slot clamping plate 505 to form a slot for clamping plastic pipes or fittings. The No. 2 dual-axis cylinder 503 is glued and fixed inside the cylinder outer frame 501. Its output end is connected to the No. 2 slot clamping plate 505. By telescopically driving the No. 2 slot clamping plate 505 to slide, the plastic pipe or fitting can be clamped or released. Six slide rods 504 are welded to the upper end of the first slot clamping plate 502. They provide guidance for the sliding of the second slot clamping plate 505 and ensure its smooth movement. The second slot clamping plate 505 can be slidably sleeved on the slide rod 504, and three triangular plates are welded on the surface. It cooperates with the slot of the first slot clamping plate 502 and clamps or releases the plastic pipe or fitting under the drive of the second dual-axis cylinder 503. The rubber strip 506 is bonded and fixed to the edge of the slots of the first slot clamping plate 502 and the second slot clamping plate 505 to increase the friction during clamping, prevent the plastic pipe or fitting from slipping, and ensure stable clamping.

[0030] The operation process of this utility model is as follows: When inspecting the outer frame 1 of the impact surface, ensure that a suitable square impact material plate, such as a steel plate or cement board, is placed inside the square outer frame 101. If it needs to be replaced, hold the front handle of the C-shaped frame 102 and lift it upwards. After lifting the old material plate, put in the new material plate and lower the C-shaped frame so that its middle part is embedded in the groove of the square outer frame for fixation. When adjusting the drop height, the operator holds an infrared remote control and sends a signal to the infrared receiving module of the controller 4. After receiving the signal, the microcontroller controls the first dual-axis cylinder 205 to retract, so that its output end is pulled out of the limiting groove of the guide rail column 201; then it controls the reduction motor 203 to start, driving the screw 202 to rotate, so that the lifting frame 204 is raised and lowered along the guide rail column slide to the target height; after reaching the target height, it controls the first dual-axis cylinder 205 to extend, and the output end is inserted into the limiting groove to fix the position of the lifting frame. When adjusting the drop angle, manually rotate the slot holder 5. The inner block 302 rotates with it inside the inner slot ring 301. After the toothed block 303 compresses the telescopic spring 304, it disengages from the original slot. When rotated to the specified angle, the telescopic spring 304 pushes the toothed block 303 into the corresponding slot, thus fixing the angle, such as 0°, 30°, 45°, etc., according to the slot distribution of the inner slot ring. When the sample is clamped, the remote control sends a clamping signal, and the microcontroller controls the second dual-axis cylinder 503 of the slot holder 5 to push the second slot clamping plate 505 to slide outward along the slide rod 504, so that a gap is left between the first slot clamping plate 502 and the second slot clamping plate 505. The plastic pipe or fitting to be tested is placed into the slots of the two slot clamping plates, ensuring that the sample is stably placed between the rubber strips 506. The clamping signal is sent to control the second dual-axis cylinder 503 to retract, driving the second slot clamping plate 505 to move closer to the first slot clamping plate 502 until the rubber strips 506 are tightly attached to the sample surface, and the clamping is completed. During the drop test, after confirming that the height, angle and sample clamping status are correct, the operator moves away from the impact surface area and sends a release signal through the remote control. The microcontroller controls the second dual-axis cylinder 503 to extend quickly, and the second slot clamping plate 505 slides along the slide bar 504 to release the sample. The plastic pipe or fitting falls onto the impact material plate at a preset angle and height under the action of gravity. When the equipment is reset, control the retraction of the No. 2 dual-axis cylinder 503 to restore the card slot clamp to its initial state. Use the remote control to adjust the lifting frame to the lowest position and turn off the equipment power. If the next set of tests is required, repeat the steps.
