[0024] like Figure 1 As shown, a trampoline impact testing device 1 is used to test the safety and reliability of a trampoline 2. A pendulum 3 impacts the trampoline 2 in different ways to test its impact resistance. Figure 2As shown, the trampoline impact testing device 1 includes a frame 11, a rack 12, a horizontal moving assembly 13, and a first driving member 14. The rack 12 is fixed to the upper end face of the frame 11. The horizontal moving assembly 13 is slidably mounted on the frame 11 and meshes with the rack 12.

The swinging component 17 is installed on the vertical moving component 15 and performs vertical movement under the action of the second driving component 16. The pendulum 3 is fixed on the swinging component 17 (see...). Figure 1 ).

[0026] like Figure 2 As shown, specifically, the trampoline impact testing device may further include a fixed wheel assembly 18, which is fixed to the side of the frame 11, and the pendulum 3 may also be mounted on the fixed wheel assembly 18.

[0027] like Figure 3 As shown, the horizontal moving assembly 13 includes a first side plate 131, a second side plate 132, a top plate 133, and a bottom plate 134. The first side plate 131 and the second side plate 132 are arranged in parallel. The top plate 133 and the bottom plate 134 are fixed above and below the first side plate 131 and the second side plate 132, respectively. The top plate 133 and the bottom plate 134 are parallel. The first side plate 131, the second side plate 132, the top plate 133, and the bottom plate 134 are connected to each other to form a rectangular frame that is fitted onto the outside of the frame 11.

[0028] The horizontal moving assembly 13 further includes an output shaft 135 and a gear 136. The output shaft 135 is connected to the output end of the first driving member 14 and passes through the first side plate 131 and the second side plate 132. The first driving member 14 is fixed to the second side plate 132. The gear 136 is fitted onto the output shaft 135 and meshes with the rack 12. The first driving member 14 drives the output shaft 135 to rotate, and the gear 136 moves while meshing with the rack 12.

[0029] The horizontal moving assembly 13 further includes a first roller group 137 and a second roller group 138. Multiple first roller groups 137 are mounted between the first side plate 131 and the second side plate 132, and the first roller groups 137 contact the upper or lower end face of the frame 11. Multiple second roller groups 138 are mounted on the first side plate 131 and the second side plate 132, and the second roller groups 138 contact the side of the frame 11. The first driving member 14 drives the output shaft 135 to rotate, and the gear 136 meshes and moves on the rack 12, driving the first roller group 137 and the second roller group 138 to rotate, thereby realizing the horizontal movement of the horizontal moving assembly 13.

[0030] like Figure 2 As shown, the vertical moving component 15 includes a housing 151 and a limiting groove 152. The housing 151 is fixed on the base plate 134. The limiting groove 152 is opened in the middle of the housing 151. The swing component 17 moves vertically in the limiting groove 152.

[0031] The vertical moving assembly 15 also includes a mounting base 153, a shaft 154, a shaft seat 155, a lead screw 156, and a coupling 157, such as Figure 4 As shown, the mounting base 153 is provided at the bottom of the interior of the housing 151. At least two symmetrical shafts 154 are provided on the mounting base 153. Shaft seats 155 are fitted onto both ends of each shaft 154. One end of each shaft 154 is fixed to the mounting base 153 via the shaft seats 155, and the other end is fixed to the top of the housing 151. The lead screw 156 is located in the middle of the housing 151. One end of the lead screw 156 is fixed to the top of the housing 151, and the other end passes through the mounting base 153 and is connected to the second driving member 16 via the coupling 157. The second driving member 16 is fixed to the lower end of the mounting base 153 or the lower end of the housing 151.

[0032] The vertical moving assembly 15 also includes a moving seat 158, which is movably mounted on the shaft 154 and the lead screw 156, and the moving seat 158 ​​moves vertically along the shaft 154 and the lead screw 156.

[0033] Specifically, the swing assembly 17 is mounted on the movable base 158 (see...). Figure 2 The swing assembly 17 follows the moving seat 158 ​​in vertical movement within the limiting groove 152.

[0034] like Figure 2As shown, the swing assembly 17 includes a first connecting rod 171, a bearing 172, a swing shaft 173, and a fixing member 174. One end of the first connecting rod 171 is fixedly mounted on the movable seat 158, and the other end of the first connecting rod 171 extends out of the limiting groove 152. The bearing 172 is fitted onto the end of the first connecting rod 171 that extends out of the limiting groove 152, the swing shaft 173 is fitted onto the outside of the bearing 172, and the fixing member 174 is fixed to the swing shaft 173. The pendulum 3 is fixed to the fixing member 174 by a connecting rope, and the pendulum 3 swings around the swing shaft 173 as the center under the action of the horizontal reciprocating motion of the horizontal moving assembly 13.

[0035] like Figure 2 As shown, the fixed wheel assembly 18 includes a second connecting rod 181 and a pulley component 182. One end of the second connecting rod 181 is fixed to the side of the frame 11, and the other end is fixed to the pulley component 182. The connecting rope of the pendulum 3 passes through the pulley component 182, and pulling or releasing the connecting rope causes the pendulum 3 to move vertically.

[0036] Specifically, the fixed wheel assembly 18 may also include a limiting member 183, which is fixed to the second connecting rod 181 or the pulley member 182 to prevent the connecting rope wrapped around the pulley member 182 from coming off.

[0037] The trampoline impact testing device 1 operates as follows: The trampoline 2 to be tested is placed below the frame 11, and the trampoline 2 is installed on the test base (not shown in the figure) according to the test items. The first driving member 14 drives the output shaft 135 to rotate, which in turn drives the gear 136 to rotate. The gear 136 meshes and moves on the spur rack 12. The first roller group 137 and the second roller group 138 follow the rotation, causing the horizontal moving component 13 to drive the vertical moving component 15 to move horizontally as a whole, so that the vertical moving component 15 is in a suitable initial position. Subsequently, the second driving member 16 drives the lead screw 156 to rotate through the coupling 157. The moving seat 158 ​​moves vertically along the lead screw 156 and the shaft 154. The pendulum 3 is fixed on the fixing member 174. The pendulum 3 follows the moving seat 158 ​​to move vertically, so that the pendulum 3 is in a suitable initial height.

[0038] After the trampoline impact testing device 1 is initially debugged according to the test items, the specific test method and number of tests are selected according to the test items to test the impact resistance performance of the trampoline 2. For example, the swing impact test method is used, using only the horizontal moving component 13 to move horizontally back and forth, so that the pendulum 3 swings and impacts the test part of the trampoline 2; or the vertical impact test method is used, using only the vertical moving component 15, so that the pendulum 3 impacts the test part of the trampoline 2 vertically; or special tests are carried out in conjunction with other devices through the fixed wheel component 18, such as pulling the pendulum 3 to simulate free fall impact or irregular jumps on the trampoline 2; or the pendulum 3 is replaced with other test instruments according to other test items required by actual needs for selection and testing.

[0039] The trampoline impact testing device in this utility model only mentions a set of horizontal and vertical moving components. The trampoline impact testing device can be modified according to specific testing requirements to increase the number of horizontal and vertical moving components and supporting parts.

[0040] This utility model provides a trampoline impact testing device. When testing a trampoline, the trampoline is fixed below the frame. The swing mode of the pendulum is adjusted by the horizontal and vertical moving components to subject the trampoline to different degrees of impact. The device is simple to operate and convenient to use, effectively expanding its application range. Furthermore, with the cooperation of the horizontal moving component, the vertical moving component, and the fixed wheel component, multiple tests can be performed on the trampoline simultaneously, saving workflow and speeding up the testing process.
