[0024] When the trampoline is in use, the two horizontal protective nets 4 and the two vertical protective nets 5 are driven by the displacement component to move between the first column 2 and the three second columns 3, so that the two horizontal protective nets 4 and the two vertical protective nets 5 are moved to the required height, which is convenient for protecting the user and avoiding accidents to the user. At the same time, the protection pad 22 is used to improve the safety performance of the trampoline, which can play a protective role when a collision occurs between the user and the column, reduce the impact on the trampoline, and also protect the user. When the trampoline is idle, the two horizontal protective nets 4 and the two vertical protective nets 5 can be rolled up by the cooperation of the winding component and the displacement component, so that the mesh surfaces of the two horizontal protective nets 4 and the two vertical protective nets 5 are correspondingly protected to avoid external damage, thereby further improving the service life of the trampoline.

[0025] like Figure 1-Figure 5 As shown, the displacement assembly includes a first L-shaped connecting block 10 and three second L-shaped connecting blocks 11, the first L-shaped connecting block 10 and the three second L-shaped connecting blocks 11 are respectively slidably connected between the inner walls of the first L-shaped slide 6 and the three second L-shaped slides 12, a threaded rod 7 is rotatably connected between the inner walls of the first L-shaped slide 6, the outer side of the threaded rod 7 is threadedly connected to the first L-shaped connecting block 10, the two ends of the two horizontal protective nets 4 and the two vertical protective nets 5 are respectively fixedly connected by the first L-shaped connecting block 10 and the three second L-shaped connecting blocks 11, the top of the first column 2 is rotatably connected with an adjusting motor 9, the output end of the adjusting motor 9 extends to the interior of the first L-shaped slide 6 and is fixedly connected to the threaded rod 7, an auxiliary rod 8 is fixedly connected between the inner walls of the second L-shaped slide 12, and the outer side of the auxiliary rod 8 is slidably connected to the second L-shaped connecting block 11.

[0026] By adjusting the motor 9, the threaded rod 7 is driven to rotate between the inner walls of the first L-shaped slide groove 6, so that the first L-shaped connecting block 10 slides between the inner walls of the first L-shaped slide groove 6, and further drives the two horizontal protective nets 4 and the two vertical protective nets 5 to move synchronously with the assistance of the three second L-shaped connecting blocks 11, so that the two horizontal protective nets 4 and the two vertical protective nets 5 can be moved to the specified height using the threaded rod 7 according to actual usage requirements.

[0027] like Figure 1-Figure 5 As shown, the winding assembly includes a first transverse winding roller 16, a second transverse winding roller 18, a first longitudinal winding roller 17 and a second longitudinal winding roller 19. The first transverse winding roller 16, the second transverse winding roller 18, the first longitudinal winding roller 17 and the second longitudinal winding roller 19 are all rotatably connected between the inner walls of the segmented connecting box 14. The outer sides of the first transverse winding roller 16, the second transverse winding roller 18, the first longitudinal winding roller 17 and the second longitudinal winding roller 19 are respectively fixedly connected to the two transverse protective nets 4 and the two longitudinal protective nets 5. A transmission mechanism is arranged between the two ends of the first transverse winding roller 16 and the first longitudinal winding roller 17 and the second longitudinal winding roller 19. One end of the first longitudinal winding roller 17 is connected to the second transverse winding roller 18. A transmission mechanism is arranged between the winding rollers 18, and the transmission mechanism includes three power bevel gears 20 and three driven bevel gears 21. Two power bevel gears 20 are fixedly connected to the two ends of the first transverse winding roller 16, and a power bevel gear 20 and a driven bevel gear 21 are fixedly connected to the two ends of the first longitudinal winding roller 17 respectively. One end of the second transverse winding roller 18 and the second longitudinal winding roller 19 are fixedly connected to the driven bevel gear 21, and the power bevel gear 20 is meshed with the adjacent driven bevel gear 21. A winding motor 15 is fixedly installed on one side of the segmented connecting box 14, and the output end of the winding motor 15 extends to the interior of the segmented connecting box 14 and is fixedly connected to the transmission mechanism.

[0028] When the protective net is being rolled up, the winding motor 15 and the adjusting motor 9 are started, and the winding motor 15 cooperates with the transmission mechanism to make the two first transverse winding rollers 16, the first longitudinal winding roller 17, the second transverse winding roller 18 and the second longitudinal winding roller 19 rotate synchronously, so that the two transverse protective nets 4 and the two longitudinal protective nets 5 are rolled up while moving steadily downward, and the two transverse protective nets 4 and the two longitudinal protective nets 5 are further protected, so that the protective net surface is prevented from being damaged by the outside when the trampoline is idle, thereby increasing the service life of the trampoline.

[0029] The utility model provides a trampoline with a protective net, and the specific working principle is as follows: when the trampoline is in use, the threaded rod 7 is driven to rotate between the inner walls of the first L-shaped chute 6 by adjusting the motor 9, so that the first L-shaped connecting block 10 slides between the inner walls of the first L-shaped chute 6, and further drives the two horizontal protective nets 4 and the two vertical protective nets 5 to move synchronously with the assistance of the three second L-shaped connecting blocks 11, so that the two horizontal protective nets 4 and the two vertical protective nets 5 move to the required height, which is convenient for protecting the user, and at the same time, the protective pad 22 is used to improve the safety performance of the trampoline, which can be used in the trampoline. It plays a protective role when a collision occurs between the user and the column, reduces the impact on the trampoline, and also protects the user. When the protective net is rolled up, by starting the winding motor 15 and the adjusting motor 9, the winding motor 15 cooperates with the transmission mechanism to make the two first horizontal winding rollers 16, the first longitudinal winding roller 17, the second horizontal winding roller 18 and the second longitudinal winding roller 19 rotate synchronously, further making the two horizontal protective nets 4 and the two longitudinal protective nets 5 be rolled up while moving steadily downward, further protecting the two horizontal protective nets 4 and the two longitudinal protective nets 5.
