[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 As shown, a safety protection trampoline for home children includes a main body 1 and a movable protection device 2; the movable protection device 2 is installed with a fixed plate 21, and the top of the fixed plate 21 is fixedly installed with several fixed blocks 22. The tops of the several fixed blocks 22 are respectively hinged with a first hydraulic cylinder 23. The output end of the first hydraulic cylinder 23 is movably installed with a first plunger 24. The top end of the first plunger 24 is hinged with a movable block 25, and the other side of the movable block 25 is fixedly installed with a movable plate 26;

[0024] During operation, the fixed plate 21 supports and fixes the whole. When driving the first hydraulic cylinder 23, the first plunger 24 expands and contracts in its inner wall, and the movable block 25 at the top of the first plunger 24 generates a linkage on the movable plate 26, so that it flips correspondingly with the movement of the first plunger 24.

[0025] Furthermore, the main body 1 is installed with a support frame 11. The top of the support frame 11 is fixedly installed with a protective rubber plate 12, and the top of the support frame 11 is fixedly installed with an elastic net 13;

[0026] During operation, through the installation of the protective rubber plate 12 by the support frame 11, when a child plays on the elastic net 13, corresponding protection is provided around the child.

[0027] Furthermore, two connecting blocks 27 are fixedly installed at the top of the support frame 11, and a movable plate 26 is hinged to one side of the two connecting blocks 27;

[0028] During operation, through the installation of the connecting block 27, a connection relationship is established between the support frame 11 and the movable plate 26. When the movable plate 26 moves, it performs circular motion with the hinge point of the connecting block 27 as the axis.

[0029] Furthermore, two fixing rods 31 are fixedly installed at the top of the fixing plate 21, and second hydraulic cylinders 32 are respectively hinged to one side of the two fixing rods 31. The output end of the second hydraulic cylinder 32 is movably installed with a second plunger 33;

[0030] During operation, through the installation of the fixing rod 31, when the movable plate 26 is converted to a horizontal state, the top of the fixing rod 31 is used to provide corresponding support for it, which is beneficial for children to move on the movable plate 26.

[0031] Furthermore, the fixing shafts 35 are respectively penetrated and movably installed on one side of the two fixing rods 31. The fixing shafts 35 are penetrated and fixedly installed with clamping joints 34, and a second plunger 33 is hinged to one side of the clamping joint 34;

[0032] During operation, the fixing rod 31 is connected to the clamping joint 34 through the fixing shaft 35. When the second plunger 33 drives the clamping joint 34 to move, the clamping joint 34 performs circular motion with the fixing shaft 35 as the axis.

[0033] Furthermore, two clamping grooves 28 are formed in the movable plate 26, and the inner walls of the two clamping grooves 28 are respectively clamped with clamping joints 34. A ladder 29 is placed on one side of the movable plate 26;

[0034] During operation, when one side of the movable plate 26 contacts the top of the fixing rod 31, the second hydraulic cylinder 32 is driven to make the clamping joint 34 flip, so that the clamping joint 34 clamps the movable plate 26 through the clamping groove 28, which is beneficial for limiting the movable plate 26 to prevent it from shaking. With the installation of the ladder 29, it is convenient for children to climb onto the top of the movable plate 26.

[0035] Working principle: By driving the first hydraulic cylinder 23, the hydraulic energy is converted into mechanical energy to enable the first plunger 24 to expand and contract in its inner wall. During the working process of the first plunger 24, the movable block 25 is used to generate a linkage effect on the movable plate 26 on one side. Driven by the acting force, the movable plate 26 rotates circumferentially with the hinge joint of the connecting block 27 as the axis. When the movable plate 26 is in a horizontal state, the second hydraulic cylinder 32 is driven to make the second plunger 33 work, so that the second plunger 33 generates a thrust or traction force on the clamping joint 34. At this time, the clamping joint 34 rotates on the fixed rod 31 with the fixed shaft 35 as the axis, and the clamping joint 34 clamps the clamping groove 28 opened on the movable plate 26, which is beneficial to limit its position. At this time, children can climb onto the top of the movable plate 26 through the ladder 29 and enter the main body 1 from the movable plate 26 to play. Similarly, by driving the first hydraulic cylinder 23, the movable plate 26 is converted into a vertical state to provide corresponding protection for children.

[0036] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
