[0036] The working steps of this embodiment are:

[0037] After the basketball hoop 5 is produced, in order to ensure the structural stability of the basketball hoop 5, it is usually necessary to perform a load test on the overall structure of the basketball hoop 5. However, the existing testing equipment only repeatedly pulls the basketball hoop 5 downward at the same position, while the actual use of the basketball hoop 5 in basketball is much more complicated. A single downward pull is not sufficient to fully evaluate the performance and safety of the basketball hoop 5 in actual applications.

[0038] In the first step, the electric slider 102 is controlled to slide on the slide rail 101, thereby driving the fixed plate 103, the linkage rod 3 and the impact block 4 to move to the position to be tested, and then the first driving member 104 is controlled to extend and retract, thereby driving the motor 105 and the impact block 4 to move downward quickly and squeeze the outer ring surface of the basketball basket 5. The basketball basket 5 is bent downward after being squeezed, and at this time, the impact block 4 will pass over the basketball basket 5. After the basketball basket 5 is squeezed and impacted quickly, high-frequency vibration will be generated, thereby realizing the scene simulation of the dunking process of the person, by controlling the first drive to drive the impact block 4 to repeatedly hit the outer ring surface of the basketball basket 5, and at the same time, the electric slider 102 drives the impact block 4 to move in a circle around the basketball basket 5, changing the impact position of the impact block 4 on the basketball basket 5, thereby realizing the impact of the impact block 4 on different positions on the basketball basket 5, enhancing the scene authenticity and improving the data reliability.

[0039] In the second step, after the detection of the outer ring surface of the basketball basket 5 is completed, the second driving member 201 is controlled to drive the first driving member 104 to move toward the inner ring surface of the basketball basket 5, until the first driving member 104 drives the impact block 4 to move downward, and the edge of the impact block 4 will squeeze and impact the inner ring surface of the basketball basket 5, and then repeat the impact test of the impact block 4 on the basketball basket 5 in the first step, thereby realizing the impact simulation of the impact block 4 on the inner ring surface of the basketball basket 5 at different positions, realizing the scene of simulating the basketball hitting the inner ring surface of the basketball basket 5, and improving the accuracy of the data.

[0040] At the same time, in the above steps, the third driving member 303 is controlled to extend and retract, so that the third driving member 303 squeezes one side of the impact block 4, thereby causing the impact block 4 and the connecting rod 301 to rotate relative to each other, that is, the impact block 4 is in a swaying state relative to the connecting rod 301, thereby changing the impact angle of the impact block 4 on the basketball hoop 5, thereby achieving different stress conditions of the basketball hoop 5 when the basketball hoop 5 is actually used, thereby comprehensively evaluating the structural strength and impact resistance of various parts of the basketball hoop 5, and then optimizing the structural design of the basketball hoop 5.

[0046] It also includes a collecting frame 701; the collecting frame 701 is fixedly connected to the testing box 1, and a plurality of water outlets connected to the collecting device are arranged at the bottom of the collecting frame 701.

[0047] All first dividing strips 603 are made of waterproof and deformable material.

[0048] The working principle of this embodiment is:

[0049] When the basketball hoop 5 is in use, when a person dunks, not only will the basketball hoop 5 be pulled and compressed, but also when the person shoots, the person will be impacted by the basketball in different directions and with different strengths. In order to further improve the scene authenticity during the test of the basketball hoop 5, in the first step of Example 1: in the initial state, the uninflated airbag 403 is in contact with the impact block 4, and the external air pump is started to allow the airflow to enter the inflation port 3001 of the linkage rod 3 through the air inlet pipe 401, and then enter the interior of the airbag 403 through the air inlet groove 3002, so that the airbag 403 gradually expands, and the airbag 403 gradually contacts the impact block 4 At the same time, the simulated cloth 402 will deform along with the airbag 403. During the expansion of the airbag 403, the depression 40301 makes some parts of the airbag 403 thinner than other parts. Therefore, when the airbag 403 expands, the part of the airbag 403 located at the depression 40301 will form a number of bulges outward, thereby driving the simulated cloth 402 attached to the airbag 403 to form a number of bulges, thereby simulating the bulges when the basketball bladder is damaged. Since the simulated cloth 402 is divided into three parts, one part is used to simulate the rough surface of a normal basketball, and the other part is used to simulate the bulging state of the basketball. Another part is used to simulate the velvet surface of a damaged basketball surface. Therefore, when the airbag 403 is inflated, the airbag 403 is in an expanded state to simulate a basketball. When it is necessary to simulate a normal basketball colliding with the basketball basket 5, the motor 105 is controlled to drive the linkage rod 3, the simulation cloth 402 and the airbag 403 to rotate, so that the rough surface of the simulation cloth 402 used to simulate a normal basketball faces the to-be-tested part of the basketball basket 5, and then the collision detection steps in Example 1 are repeated to simulate the collision of the basketball with the basketball basket 5. By analogy, the linkage rod 3, the simulation cloth 402 and the airbag 403 are driven to rotate by controlling the motor 105. , so that the inflated airbag 403 drives different simulated surfaces on the simulated cloth 402 toward the tested parts of the basketball basket 5, and impacts various parts of the basketball basket 5, thereby simulating the actual use situation, and testing the effects of basketballs in different states hitting the basketball basket 5, so as to comprehensively evaluate the performance and durability of the basketball basket 5; at the same time, when the air pump is controlled to inflate the inside of the airbag 403, the inflation condition inside the airbag 403 can be changed, such as insufficient inflation and over-inflation, thereby simulating the impact force of the basketball when the air pressure is insufficient, testing the response of the basketball basket 5 under lower impact capacity, and checking whether the basketball basket 5 can remain stable.

[0050] When people play basketball on a court and it rains, the surface of the basketball will be soaked. In order to test the impact effect of the soaked basketball surface on the basketball hoop 5, after the airbag 403 is inflated, the pump inside the water tank 501 is started to allow water to flow into the liquid inlet chamber 3003 of the linkage rod 3 through the water inlet pipe 502, and then flow out through the liquid outlet 3004 on the lower side of the linkage rod 3, thereby wetting the simulated cloth 402 on the surface of the airbag 403 and making the simulated cloth 402 wet, so that the wet basketball hits the basketball hoop 5, so as to evaluate the anti-slip performance of the basketball hoop 5 and the influence of the basketball hoop 5 on the rebound effect of the wet basketball, thereby ensuring the safety of the players.

[0051] To further test the impact effect of the basketball on the basketball basket 5 under different states, when the pump inside the water tank 501 is started, the liquid inlet chamber 3003 of the linkage rod 3 is divided into three parts by the partition 601, and each part is not connected to each other. Figure 8 As shown, at this time, the liquid outlet 3004 on the lower side of the linkage rod 3 is also divided into three parts, and each part of the liquid outlet 3004 corresponds to the three simulated surfaces on the simulated cloth 402. When it is necessary to test the impact effect of the damaged velvet surface of the basketball on the basketball hoop 5 in a wet state, the solenoid valve 602 on the liquid inlet chamber 3003 connected to the corresponding liquid outlet 3004 is controlled to connect the water inlet pipe 502 with the liquid inlet chamber 3003 of this part, and then the pump is controlled to make a smaller water flow overflow through the liquid outlet 3004 and slide down along the arc surface of the inflated airbag 403, so that the water flow only slowly wets the velvet part of the damaged basketball on the simulated cloth 402, thereby improving the diversity of the test data, and by controlling the corresponding solenoid valve 602 switch, the simulated surfaces on the simulated cloth 402 are wetted respectively, so as to compare the test results and optimize the design of the basketball hoop 5.

[0052] When the corresponding solenoid valve 602 is controlled to switch, so that the water inlet pipe 502 is connected to the liquid inlet cavity 3003 of this part, and the water flows out through the liquid outlet 3004, the different simulation surfaces on the simulation cloth 402 are isolated by the first dividing strip 603, thereby preventing the water from flowing over adjacent simulation surfaces and interfering with other simulation surfaces, thereby avoiding affecting the test results.

[0053] When the temperature drops suddenly, the surface of the basketball hoop 5 in some areas is frozen. At this time, the basketball hoop 5 will be more brittle and hard than at normal temperature, and its toughness will be reduced. Therefore, when the basketball hoop 5 is hit by a basketball after the surface is frozen, it is more likely to be brittle fracture. In order to further simulate the scene of the basketball hoop 5 in actual use during the test process, the simulation cloth 402 is divided into four surfaces by the second dividing strip 604, such as Figure 7 and Fig. 9As shown, the water outlet 40202 of the simulation cloth 402 is located between the two second dividing strips 604, and the water outlet 40202 is located on the simulation surface of the simulation cloth 402 for simulating the spherical bulge state. At this time, by controlling the solenoid valve 602 corresponding to the simulation surface, the water flows out through the liquid outlet 3004 corresponding to the lower side of the linkage rod 3, and the water is guided into the water outlet 40202 through the liquid outlet 3004 connected to the water outlet 40202, and sprayed out through the water outlet 40202. At the same time, the first driving member 104 is controlled to drive the simulation cloth 402 and the airbag 403 to flow out. Move downward until the water outlet 40202 and the basketball hoop 5 are at the same height, then control the motor 105 to rotate so that the water outlet 40202 faces the surface of the basketball hoop 5, and then control the electric slider 102 to drive the simulation cloth 402 and the air bag 403 to slide on the slide rail 101, so as to spray water on the basketball hoop 5 in a circular shape, and then control the temperature controller 605 to lower the temperature in the test box 1, so that the wetted basketball hoop 5 gradually freezes, and then repeat the above-mentioned impact test steps to simulate the basketball hitting the frozen basketball hoop 5, so as to better select the material for making the basketball hoop 5.

[0054] When the basketball basket 5 is frozen, when the airbag 403 simulates the basketball hitting the basketball basket 5, part of the ice on the basketball basket 5 will gradually break and fall into the test box 1, and the falling crushed ice will be collected by the collection frame 701, and the melted crushed ice will be guided to the external collection equipment through the water outlet, so as to prevent the crushed ice from melting and gathering in the test box 1, causing the parts in the test box 1 to get damp.

[0055] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
