Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a sponge ball-drop rebound testing machine for experiments, including a support device. The support device includes a base 1, and support pads are provided at the four corners of the base. The tester 11 is arranged on the top of the printer 13, and the printer 13 is installed on the base 1. The printer is used to print the data detected by the tester.

[0026] The inspection cylinder 20 is transparent, which is a glass cylinder or a transparent plastic cylinder. The bottom of the inspection cylinder 20 is installed on the annular seat 27. The four corners of the bottom of the inspection table 2 are connected to the top of the base 1 through support legs 17. The annular seat 27 is communicated with the inspection table 2 and the inspection cylinder 20;

[0027] A draw-out groove 16 is opened on the base 1 below the inspection table 2. One end of the draw-out groove 16 penetrates through the edge of the inspection table and communicates with the outside. A bearing plate 14 is placed in the draw-out groove 16. A placement groove 15 for placing the sponge is opened on the top of the bearing plate 14. When the bearing plate 14 is placed in the draw-out groove 16, the sponge is located below the inspection cylinder 20. A handle for facilitating the operator to hold is also connected to the end of the bearing plate 14.

[0028] The top of the detection cylinder 20 is mounted on the end cover 8. A support tube 9 is coaxially arranged inside the detection cylinder 20. The support tube 9 is made of non-magnetic material, such as an aluminum tube or a stainless steel tube, etc. The support tube 9 is coaxially and movably connected to the center of the end cover 8, so that the support tube 9 can telescopically move inside the end cover 8. A cylindrical outer shell 24 is coaxially installed at the lower end of the support tube 9. An electromagnet 25 is arranged inside the cylindrical outer shell 24. As Figure 1 shown, the wire connected to the electromagnet 25 extends out from the top of the support tube 9 and is then connected to the tester 11. When the electromagnet 25 is energized, the detection ball 26 is adsorbed below the cylindrical outer shell 24. The detection ball 26 is made of magnetic material. After power-off, the detection ball 26 falls into the placement groove 15. The detection ball 26 is made of magnetic material;

[0029] As Figure 3 shown, the bottom of the cylindrical outer shell 24 is a spherical surface that is recessed inward. Under the adsorption action of the electromagnet, the detection ball 26 automatically slides down to the center of the spherical surface.

[0030] The lifting of the support tube 9 is driven by a lifting mechanism. The lifting mechanism can drive the support tube 9 to telescopically move inside the detection cylinder 20. When the support tube 9 descends, the electromagnet is placed at the bottom of the detection cylinder 20. When the support tube 9 rises, the electromagnet is placed at the top of the detection cylinder 20. Of course, the detection ball is also lifted to a high position in the detection cylinder 20 under the suction force of the electromagnet;

[0031] When the detection sponge is placed below the detection cylinder 20, the detection ball can be freely dropped in the detection cylinder 20 by power-off, and the operator can directly observe the bounce height of the detection ball.

[0032] As Figure 1 and Figure 2 shown, the above-mentioned lifting mechanism includes a stabilizing frame 18 installed on the side surface of the detection cylinder 20. The upper and lower ends of the stabilizing frame 18 are respectively connected to the annular seat 27 and the end cover 8. The stabilizing frame 18 is used to support the detection cylinder 20, so as to improve the structural strength of the detection cylinder 20 and make the detection cylinder 20 steel frame stable;

[0033] A driving motor 3 is installed at the bottom of the stabilizing frame 18. The driving motor 3 is connected to the tester through a wire. A transmission lead screw 4 is coaxially connected to the top of the driving motor 3. The transmission lead screw 4 is parallel to the axis of the detection cylinder 20, and both ends of the transmission lead screw 4 are rotatably installed in the support 19. The supports 19 are respectively arranged at both ends of the stabilizing frame 18;

[0034] A lead screw 4 is provided with a matching nut 6. One side of the nut 6 is connected to the bottom of a support rod 7. The support rod 7 is arranged parallel to the lead screw 4. The top of the support rod 7 extends above the detection cylinder 20 and its top is connected to the top of a support tube 9 through a connecting frame 10. And the support rod 7 movably penetrates through a support 19. So when the driving motor 3 rotates, it can drive the lead screw 4 to rotate. The lead screw 4 drives the nut 6 to move up and down, so that the nut 6 drives the support rod 7 to move up and down, as Figure 2 shown. A chute 21 is provided on one side of the stabilizing frame 18 away from the detection cylinder. A slider placed in the chute 21 is provided on the side surface of the nut 6, making the up and down movement of the nut 6 more stable.

[0035] Furthermore, as Figure 1 shown, a photoelectric sensor 23 is installed on one side of an annular seat 27 through a sensor bracket 22. The photoelectric sensor 23 can also be replaced with an infrared sensor. The irradiation end of the photoelectric sensor 23 faces the bottom of the detection cylinder 20. The photoelectric sensor 23 is connected to a tester 11 through a wire. The photoelectric sensor 23 is used to monitor the initial time when the detection ball lands on the sponge, continue to monitor the bounce and fall times, and transmit this information to the tester 11 for analysis, so as to obtain the height of the detection ball and calculate various data of the sponge.

[0036] Furthermore, in order to facilitate the removal of the detection ball, as Figure 1 shown, an outlet 5 is opened at the bottom of the detection cylinder 20. One side of the outlet 5 is rotatably connected to an arc-shaped sealing cover 12. The other side of the arc-shaped sealing cover 12 is connected to the edge of the outlet 5 through a buckle. And the arc-shaped sealing cover is closed during the detection process.

[0037] Based on the above embodiments, it can be further optimized. Buttons for controlling the on-off of the electromagnet, buttons for controlling the forward and reverse rotation of the driving motor, and buttons for controlling the printer to print are provided on the surface of the tester 11, etc.

[0038] Based on the above embodiments, it can be further optimized. Scales are also provided on the surface of the detection cylinder, which is convenient for the operator to directly observe.

[0039] To sum up, the usage process of the present utility model is as follows: 1. When in use, first control to place the cut sponge in the placement groove 15, then place the bearing plate 14 in the draw groove 16, then place the detection ball into the detection cylinder 20 from the outlet 5, then close the arc-shaped sealing cover 12, then energize the electromagnet, and then control the driving motor to rotate to drive the electromagnet to descend, adsorb the detection ball and lift it to a high place;

[0040] 2. Control the electromagnet to power off, let the detection ball fall freely, the detection ball hits the sponge and bounces, and the bouncing process is constantly detected by the photoelectric sensor;

[0041] 3. If you want to repeat the detection process, you only need to repeatedly control the lifting of the electromagnet. The operation is simple and convenient to use.
