Description

Technical Field

[0001] The present application belongs to the field of trampoline testing devices, and specifically relates to a testing device. Background Art

[0002] In the prior art, a trampoline has an elastic surface, and people jump on the elastic surface to bounce the body up, and exercise and entertainment are achieved through jumping and leg movements. In order to control people within the range of the elastic surface, the trampoline is provided with a fence barrier around the elastic surface to prevent people from leaving the range of the elastic surface. Therefore, the fence barrier is often impacted. In order to ensure the impact resistance of the fence barrier, it is necessary to test the impact resistance of the fence barrier. The existing detection technology suspends an impact object in front of the fence barrier, and the impact object can rotate around the hanging point. The impact object is aligned with the center position of the fence barrier. After the impact object is deflected by the inclined pull mechanism, the impact object is released to impact the fence barrier. The impact resistance of the fence barrier is tested by testing the angle change of the fence barrier before and after the impact. The fence barrier has an opening for people to enter and exit. The fence barrier also needs to be tested for its impact resistance on both sides of the center position and around the opening. Therefore, it is necessary to control the impact force of the fence barrier to meet the test needs. The magnitude of the impact force is related to the pendulum length and swing angle of the impact object. The impact object needs to be directly opposite the center position of the fence barrier. Therefore, in the prior art, the distance between the hanging point of the impact object and the center of the impact object is fixed, and the impact force can only be increased by continuously adjusting the swing angle. Therefore, the higher the height of the impact object relative to the ground, the larger the site range required for the test, and the greater the gravity of the impact object that needs to be overcome, the higher the layout and power requirements of the mechanism for driving the impact object to deflect.

[0003] There is an existing trampoline testing standard, which is to align the impact object with the center of the fence barrier, rotate the impact object around the hanging point, and control the distance between the deflection point of the impact object and the center of mass of the impact object as a standard value, and then control the impact object to deflect to a fixed angle to standardize the impact force of the impact object, so as to perform a standard test on the trampoline. Different fixed values ​​and fixed angles are set for different trampolines, and the existing technology cannot be applied. The reason is that when the distance between the deflection point of the impact object and the center of mass of the impact object is controlled, the impact object cannot be aligned with the test center of the barrier, resulting in the inability to conduct the test, or the height of the trampoline needs to be adjusted so that the impact object can be aligned with the test center, and the detection process is cumbersome and the detection efficiency is low. When the impact object is controlled to be aligned with the center of the fence barrier, the existing technology cannot control the distance between the hanging point and the center of mass of the impact object, resulting in that at a fixed angle, the distance between the deflection point of the impact object and the center of mass of the impact object is much greater than the fixed value, resulting in the impact force of the impact object failing to meet the test requirements and the test results failing to meet the standards. Summary of the invention

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The present application can facilitate the impact of the impact object on the surface to be impacted by setting the impact object relative to the surface to be impacted. By setting an oblique-stayed mechanism, the impact object can be driven to deflect, so that the impact object has sufficient impact force, and sufficient dynamic load can be applied to the surface to be impacted to detect the impact resistance of the test piece. By setting a first steering member, the first steering member can abut against the first flexible cable, and the oblique-stayed mechanism drives the impact object to deflect. Through the abutment of the first steering member and the first flexible cable, the impact object rotates around the first steering member, and the first steering member becomes the pivot point of the swing of the impact object. By setting a movable bracket that can be movably set on the fixed bracket, the position of the pivot point of the swing of the impact object can be adjusted, and the distance from the pivot point to the center of mass of the impact object can be adjusted. By adjusting the position of the first steering member and adjusting the length of the first flexible cable, the distance from the pivot point to the center of mass of the impact object can be ensured to be unchanged, so that the test device can detect the test surface of the test piece at different heights. By controlling the deflection angle of the impact object and the distance between the swing pivot point of the impact object and the center of the impact object, the impact force of the impact object can be accurately controlled so that the impact force meets the test standard, improves the detection efficiency, ensures the accuracy of the detection, and improves the applicability of the test device.

[0019] 2. As a preferred embodiment of the present application, by setting the first steering member to have an arc-shaped guide surface set toward the first flexible cable, when the first steering member contacts the first flexible cable, wear of the first flexible cable can be avoided, thereby increasing the service life of the first flexible cable. At the same time, by setting the arc-shaped guide surface, the rotation of the first flexible cable can be facilitated, thereby improving the smoothness of the rotation and facilitating the driving of the inclined-stayed mechanism.

[0020] Furthermore, by arranging the first steering member to be rotatably disposed on the movable bracket, during the process of the diagonal-stayed mechanism driving the impact object to deflect, the friction between the first flexible cable and the first rotating member can be alleviated by the rotation of the first steering member, thereby reducing the wear of the first flexible cable. At the same time, by arranging the first steering member to be rotatably disposed on the movable bracket 43, it can be more convenient for the diagonal-stayed mechanism to drive the impact object to deflect around the first steering member.

[0021] 3. As a preferred embodiment of the present application, by setting a second steering member, the first flexible rope is set between the first steering member and the second steering member, the first steering member and the second steering member can guide the first flexible rope, so as to improve the impact of the impact object on the surface to be impacted along a preset impact trajectory, and by setting the second steering member on the side of the first steering member facing away from the surface to be impacted, after the impact object impacts the surface to be impacted, the deflection of the first flexible rope can be limited, the shaking amplitude of the impact object can be reduced, and the impact object can be restored to its initial state as soon as possible, so as to facilitate the next impact test and improve the test efficiency.

[0022] 4.

By setting the first guide part to be able to move up and down, the applicability of the test device is further improved. When applied to test surfaces of different heights, by adjusting the position of the first guide part, it can be ensured that the impact object is subjected to greater force in the horizontal direction, and the stability of the swing of the impact object is improved. Moreover, under the same power condition, the direction of the force applied can be adjusted by the first guide part to increase the swing amplitude of the impact object and reduce the requirements for the drive assembly of the inclined-stayed mechanism.
