Description

Technical Field

[0001] The utility model belongs to the technical field of ski board testing devices, in particular to a ski board impact testing device. Background Art

[0002] As a popular winter sport, skiing has always been a focus of safety. As core equipment in skiing, the structural stability and material durability of skis are crucial to ensuring athlete safety. During skiing, skis may be subject to various impacts, such as falls and collisions with obstacles. These impacts can damage or break the skis, potentially injuring the athletes. Therefore, rigorous impact testing is required after production to evaluate their impact resistance in actual use. This is an essential step to ensure product quality and athlete safety.

[0003] After searching, the patent with publication number CN220251313U discloses a ski impact test device, which includes a support frame, an angle plate provided on the support frame, a hammer connected to the center of the angle plate, a ski mounting bracket provided on the side of the hammer, a base plate provided on the ski mounting bracket, a plurality of support columns provided on the base plate, and a pressure plate provided on the support columns. The spacing between the base plate and the pressure plate is adjustable, and a ski is provided between them. The ski can be fixed between the base plate and the pressure plate horizontally or vertically, and the hammer can be connected to the side of the ski. By providing an angle plate on the support frame and connecting the hammer to the angle plate, the impact force can be adjusted by adjusting the falling angle of the hammer, which is convenient to use. At the same time, the angle plate, ski mounting bracket and hammer can all be used according to different scenarios to ensure test accuracy.

[0004] However, when the above device is used, the impact is performed by the inertia of the impact hammer during its falling process; when the impact force needs to be adjusted, a counterweight can only be added to the impact hammer. This method requires manual lifting of the impact hammer, which increases labor costs and is likely to cause injuries to workers when lifting the impact hammer. Summary of the Invention

[0005] The purpose of the utility model is to provide a ski board impact testing device, which uses the impact force generated during the air pressure release process as power to perform impact, thereby reducing labor costs and preventing workers from being injured.

[0026] Reference Figure 1-5 A ski impact test device provided by an embodiment of the present invention will now be described. A ski impact test device comprises a support frame 1, a first support plate 2 being fixedly connected to the top of the support frame 1, two symmetrically distributed first clamping blocks 3 being slidably mounted on the top of the first support plate 2, a second clamping block 4 being slidably mounted on the top of the first clamping block 3, a second support plate 5 being fixedly connected to one side of the first clamping block 3, a pressurizing assembly 6 being fixedly mounted on the top of the second support plate 5, an air storage tank 7 being fixedly mounted on the exhaust end of the pressurizing assembly 6, an electromagnetic valve 8 being mounted on the exhaust end of the air storage tank 7, an air pipe 9 being mounted on the exhaust end of the electromagnetic valve 8, and an impact block 10 being slidably mounted inside the air pipe 9.

[0027] When in use, first clamp the ski to be tested between the first clamping block 3 and the second clamping block 4, then start the pressurizing component 6 to pressurize the external air, and then transport the high-pressure air to the inside of the air tank 7. When the pressure inside the air tank 7 reaches the required value, open the solenoid valve 8 to allow the high-pressure air to enter the inside of the air pipe 9. The force generated by the release of the high-pressure air inside the air pipe 9 pushes the impact block 10 forward to impact the front end of the ski.

[0028] Two symmetrically distributed sliding rods 11 are fixedly connected to the top of the first support plate 2 , and two symmetrically distributed sliding blocks 12 are fixedly connected to the top of the first clamping block 3 . Sliding holes 13 are opened inside the sliding blocks 12 , and the sliding holes 13 are located on the sliding rods 11 .

[0029] When in use, the two first clamping blocks 3 can be moved by the cooperation between the sliding rod 11 and the sliding hole 13, so as to facilitate clamping of skis of different widths.

[0030] The top of the first clamping block 3 is fixedly connected to two symmetrically distributed support rods 14, the top of the first clamping block 3 is fixedly connected to a screw 15, and three circular holes 16 are opened inside the second clamping block 4, and the circular holes 16 correspond to the support rods 14 and the screw 15. The outer wall of the screw 15 is threadedly installed with a butterfly nut 17, and the opposite surfaces of the first clamping block 3 and the second clamping block 4 are fixedly installed with anti-slip pads 18.

[0031] When in use, the ski to be tested is placed between the first clamping block 3 and the second clamping block 4, and then the butterfly nut 17 is installed on the screw 15. By rotating the screw 15, the second clamping block 4 can be pressed downward to firmly clamp the ski; the anti-slip pad 18 plays an anti-slip role.

[0032] The pressurizing assembly 6 includes a cylinder body 601, a driving motor 602, a camshaft 603, a connecting rod 604, a piston 605 and an air hole 608. The cylinder body 601 is fixedly installed on the top of the second support plate 5, and the driving motor 602 is fixedly installed on the outer wall of the cylinder body 601. The camshaft 603 is movably installed inside the cylinder body 601, and the camshaft 603 is installed at the output end of the camshaft 603. The connecting rod 604 is movably installed on the top of the camshaft 603, and the piston 605 is movably installed on the top of the connecting rod 604. The piston 605 is slidably installed inside the cylinder body 601, and the outer wall of the cylinder body 601 is provided with an air hole 608.

[0033] When in use, the drive motor 602 is started, and the output end of the drive motor 602 drives the camshaft 603 to rotate, and drives the piston 605 to move up and down inside the cylinder 601 through the connecting rod 604, so that the outside air can be sucked into the cylinder 601 and then pressurized. When the piston 605 moves up and down inside the cylinder 601, the gas at the bottom of the piston 605 can be discharged or entered through the air hole 608, so that the piston 605 moves more smoothly.

[0034] An intake check valve 606 is fixedly installed on the top of the cylinder body 601 , and an exhaust check valve 607 is fixedly installed on the top of the cylinder body 601 .

[0035] When the piston 605 moves downward, negative pressure is generated inside the cylinder 601. At this time, outside air can enter the cylinder 601 through the air intake check valve 606. Then the piston 605 moves upward, the air intake check valve 606 is closed, and air enters the air storage tank 7 through the exhaust check valve 607. As the piston 605 moves back and forth multiple times, air can be continuously added to the air storage tank 7, and the air inside the air storage tank 7 can be pressurized.

[0036] A pressure gauge 801 is fixed to the top of the solenoid valve 8 .

[0037] During use, the pressure inside the gas storage tank 7 can be detected in real time through the pressure gauge 801.

[0038] The outer wall of the impact block 10 is fixedly connected to a push rod 1001, which is located inside the trachea 9. The top of the second support plate 5 is fixedly connected to a support block 501, and a limiting groove 502 is provided on the top of the support block 501. The bottom of the impact block 10 is fixedly connected to the limiting block 1002, and the limiting block 1002 is located inside the support block 501.

[0039] When the solenoid valve 8 is opened, high-pressure air enters the air pipe 9, and then the pressure is released instantly, pushing the push rod 1001 to slide, and at the same time driving the impact block 10 to move and hit the ski board. When the impact block 10 moves, the cooperation between the limit block 1002 and the limit groove 502 can prevent the position of the impact block 10 from shifting during sliding.

[0040] Working principle: First, place the ski to be tested between the first clamp 3 and the second clamp 4, then install the butterfly nut 17 on the screw 15. By rotating the screw 15, the second clamp 4 can be pressed downward to firmly clamp the ski.

[0041] Next, the drive motor 602 is started, and the output end of the drive motor 602 drives the camshaft 603 to rotate, and drives the piston 605 to move up and down inside the cylinder 601 through the connecting rod 604. When the piston 605 moves downward, negative pressure is generated inside the cylinder 601. At this time, outside air can enter the interior of the cylinder 601 through the air intake check valve 606. Then the piston 605 moves upward, the air intake check valve 606 is closed, and air enters the interior of the air storage tank 7 through the exhaust check valve 607. As the piston 605 moves back and forth multiple times, air can be continuously added to the interior of the air storage tank 7, and the air inside the air storage tank 7 can be pressurized.

[0042] The pressure inside the air tank 7 can be observed through the pressure gauge 801. When the pressure reaches the required value, the solenoid valve 8 is opened to allow high-pressure air to enter the air pipe 9, and then the pressure is released instantly, pushing the push rod 1001 to slide, and at the same time driving the impact block 10 to move and hit the ski board. When the impact block 10 moves, the cooperation between the limit block 1002 and the limit groove 502 can prevent the impact block 10 from shifting during the sliding process.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
