For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example, see Figures 1 to 6A strength testing device for a sports skateboard comprises a strength testing platform 1, on which a test groove is provided, the setting of the test groove is to meet the collection function of rubber wear materials in the pulley detection process, and a plurality of groups of two test force cylinders 2 for pulley motion simulation are arranged in the test groove, the test force cylinder 2 contacts the same skateboard pulley, and its high-speed rotation can simulate the effect of the rotation of the skateboard pulley, the two ends of the test force cylinder 2 are connected to the bearing end seat 3 through a driving device, and the inner wall of the test groove is rotatably connected to the bearing end seat 3 through a support member 4;

[0031] A friction layer is provided on the outer side wall of the test stress-bearing cylinder 2 for effectively testing the wear resistance of the pulley.

[0032] The bearing end seat 3 is arranged in an inverted triangle shape with the center of gravity at the bottom. When the bearing end seat 3 is deflected at a small angle under the action of the incomplete gear 15, the center of gravity can be set to achieve a rapid reset effect, thereby ensuring the effect of continuous pressure detection on the sports skateboard.

[0033] Furthermore, the driving device includes a transmission cavity opened in the bearing end seat 3, the test force cylinder 2 is fixedly connected with a rotating shaft 10, the end of the rotating shaft 10 passes through the transmission cavity and is fixedly connected with a rotating gear 11, a transmission port is opened on the side wall of the test groove, and a main driving shaft 12 is rotatably connected to the inner wall of the transmission port, and the main driving shaft 12 is rotatably connected to the inner wall of the test groove through a bearing, so as to realize effective support for the main driving shaft 12 and ensure normal transmission;

[0034] The end of the main driving shaft 12 passes through the transmission cavity and is fixedly connected to a driving gear 13 meshing with the two rotating gears 11 . The bearing end seat 3 is provided with an arc-shaped opening 26 for the main driving shaft 12 to pass through.

[0035] Furthermore, both ends of the bearing end seat 3 are fixedly connected with support shafts 14, the support member 4 is composed of an L-shaped support frame and a circular support frame, and the L-shaped support frame and the circular support frame are rotatably connected to the support shafts 14 on both sides of the bearing end seat 3 respectively, and the end of the support shaft 14 on one side is fixedly connected with an incomplete gear 15, and the main drive shaft 12 is fixedly provided with a torque gear 16 meshing with the incomplete gear 15.

[0036] It is worth noting that when the torque gear 16 rotates, the incomplete gear 15 will rotate, driving the load-bearing end seat 3 to rotate eccentrically. In the process of eccentricity of the load-bearing end seat 3, the test force cylinder 2 will be deflected. In the process of deflection, the skateboard pulley between the two test force cylinders 2 will be deflected, thereby changing the height of the skateboard and generating a height difference. In the process of height difference change, the pressure acting on the skateboard will change, thereby simulating the process of athletes jumping on the skateboard and simulating the actual strength change of the skateboard under the action of stress change, thereby achieving a simulation effect.

[0038] The strength test bench 1 is provided with a load simulation device at the position of the test force cylinder 2, and the load simulation device includes a support platform 5 provided on the strength test bench 1, and a plurality of pressure cylinders 6 are provided on the support platform 5, and the output ends of the plurality of pressure cylinders 6 are commonly connected to a pressure platform 7, and a plurality of relatively arranged pressure slide rails 8 are provided at the bottom of the pressure platform 7, and the pressure slide rails 8 are slidably provided with relatively arranged pressure blocks 9;

[0039] A pressure-bearing slide groove is arranged on the opposite side of the pressure slide rail 8, and both ends of the pressure block 9 are fixedly connected with a pressure-bearing slider 20 located in the pressure-bearing slide groove, and the bottom of the pressure block 9 is densely provided with pressure balls.

[0040] The pressure platform 7 is provided with an adjustment control component for adjusting the pressure block 9, and the adjustment control component includes an adjustment motor 21 arranged on the pressure platform 7. A vertical rotating shaft 22 is rotatably arranged at the bottom of the pressure platform 7. A rectangular transmission groove is opened in the pressure platform 7. The end of the vertical rotating shaft 22 passes through the rectangular transmission groove and is fixedly connected to a horizontal worm gear 23. The output end of the adjustment motor 21 passes through the rectangular transmission groove and is fixedly connected to a driving worm meshing with the horizontal worm gear 23.

[0041] Furthermore, an adjusting rack 24 is fixedly connected to the top of the pressure block 9, and an adjusting gear 25 is fixedly connected to the end of the vertical shaft 22. The adjusting racks 24 on both sides of the adjusting gear 25 are staggered and meshed with both sides of the adjusting gear 25 respectively.

[0042] The above-mentioned structure can meet the need to test different parts of the sports skateboard, and can change the position of the pressure block 9 to perform simulation tests at different positions, thereby ensuring the accuracy of the test and adapting to the test needs of different types of sports skateboards.

[0043] A displacement sensor is provided at the bottom of the test tank. The displacement sensor is arranged between two groups of test force cylinders 2, and can detect the deformation of the slide plate during testing. During the compression deformation of the slide plate, its height will change. Through the setting of the displacement sensor, the displacement change can be accurately detected, thereby detecting the relationship between the deformation of the slide plate and the load.

[0044] When the present invention detects the motion skateboard, the pulleys on the front and rear sides of the motion skateboard are arranged between the relatively arranged test force cylinders 2, and multiple groups of tests can be carried out simultaneously as needed. At this time, the pressure cylinder 6 on the load simulation device is controlled according to the pressure required for the test, so that it drives the pressure block 9 thereon to move downward, and applies pressure to the motion skateboard to perform a load-bearing test in a simulated motion state. In this process, the pressure position of the pressure block 9 on the skateboard can be changed to test the change in the strength of the skateboard at the pressure position of the skateboard, so as to ensure that the strength of the skateboard meets the standard when the center of the motion skateboard is loaded, and to perform a strength change test on the skateboard material;

[0045] In this process, a simulated strength test can be performed according to the detection requirements, and the driving motor 17 is controlled to drive the linkage shaft 18 to rotate, and the main driving shaft 12 connected to the linkage worm gear 19 is driven to rotate. During the rotation of the main driving shaft 12, the two rotating gears 11 meshing with the driving gear 13 at its end are rotated, driving the rotating shaft 10 to rotate. During the rotation, the pulley of the motion skateboard is driven at high speed to simulate the state of the actual sliding process. The pulley rotates during the load rotation process, which can realize the effective detection of the wear resistance of the pulley.

[0046] During the rotation of the test stress cylinder 2, the torque gear 16 arranged on the main drive shaft 12 will drive the incomplete gear 15 to rotate, and drive the bearing end seat 3 to rotate eccentrically. During the eccentricity of the bearing end seat 3, the test stress cylinder 2 will be deflected. During the deflection, the skateboard pulley between the two test stress cylinders 2 will be deflected, thereby changing the height of the skateboard and generating a height difference. During the height difference change, the pressure acting on the skateboard will change, thereby simulating the process of athletes jumping on the skateboard and simulating the actual strength change of the skateboard under the action of stress change, so as to achieve the effect of simulation.

[0047] In this process, the pressure position of the pressure block 9 on the slide can be changed according to the pressure position of the required load, and simulation tests at different positions can be carried out to ensure the accuracy of the test.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
