Description

Technical Field

[0001] The utility model relates to a trampoline peripheral protection device, belonging to the technical field of trampolines. Background Technique

[0002] The trampoline frame is made of metal, and a PP jumping cloth, a nylon jumping cloth, a rubber cloth, etc. are installed on the inner wall of the frame as the trampoline surface. A protection device can be installed around the trampoline for protecting users during daily entertainment.

[0003] According to the authorized patent CN202322389005.5, it can be known that when the user falls and presses down the trampoline body and the second jumping net in this patent, the generated elastic force makes the user bounce up. At the same time, the installation ring and the protection part bounce up, and the protection part bounces up together with the user, so that the protection part can better protect the user, prevent the user from falling outside the trampoline body, and can prevent the user from bumping into the support rod. However, the protection device is generally fixedly connected to the top of the trampoline, and it will be relatively troublesome when the protection device needs to be disassembled. And an elastic net is fixedly connected inside the protection device, and when the elastic net needs to be replaced, it cannot be replaced quickly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a trampoline peripheral protection device. The structure of the utility model is simple and convenient to use. It can disassemble the installation mechanism on the top of the trampoline, and at the same time can quickly replace the elastic net to solve the problems proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A trampoline peripheral protection device includes a trampoline body. A support column is fixedly connected to the bottom of the trampoline body, and an installation mechanism is fixedly connected to the top of the trampoline body. A protection mechanism is installed between the installation mechanisms.

[0007] The installation mechanism includes a clamping ring. A positioning hole is opened in the inner wall of the clamping ring. A fixing rod is installed inside the clamping ring. A compression spring is fixedly connected to the outside of the fixing rod. A limiting column is fixedly connected to the outside of the compression spring. A stabilizing rod is fixedly connected to the top of the fixing rod. A connecting plate is clamped to the top of the stabilizing rod.

[0008] The protection mechanism includes an adapter plate. A threaded tube is fixedly connected to the outside of the adapter plate. A screw rod is threadedly connected to the inside of the threaded tube. A rotating cover is fixedly connected to the outside of the screw rod. A push rod is fixedly connected to the end of the screw rod away from the rotating cover. An extrusion cover is fixedly connected to the outside of the push rod.

[0009] Furthermore, the support columns are symmetrically distributed at the bottom of the trampoline body, and the clamping rings are symmetrically distributed at the top of the trampoline body. By symmetrically distributing the support columns at the bottom of the trampoline body, the trampoline body can be supported and stabilized.

[0010] Furthermore, the positioning holes are symmetrically distributed in the inner wall of the clamping ring, and the limiting posts are movably connected to the outside of the fixed rod through compression springs. By the limiting posts being located in the positioning holes inside the clamping ring, the fixed rod can be installed inside the clamping ring.

[0011] Furthermore, the limiting posts are located inside the positioning holes, and the connecting plate is installed on the tops of the two fixed rods through the stabilizing rods. By the connecting plate being located on the tops of the two fixed rods, the fixed rods can be kept stable on the top of the trampoline body.

[0012] Furthermore, the connecting plates are symmetrically distributed on the outside of the fixed rods, and the screw rod is rotatably connected to the inside of the threaded tube through the rotating cover. By driving the screw rod to rotate inside the threaded tube through the rotating cover, the screw rod drives the push rod to move.

[0013] Furthermore, the push rod passes through the inside of the connecting plate, and the extrusion cover is movably connected between the two connecting plates through the push rod. By the cooperative use of the push rod and the extrusion cover, the extrusion cover can position the elastic net between the connecting plates.

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) By providing the trampoline body in the present utility model, a support column is fixedly connected to the top of the trampoline body, so that the trampoline body is kept stable. When it is necessary to disassemble the installation mechanism on the top of the trampoline body, first, the connecting plate is removed from the stabilizing rod on the top of the fixed rod, and then the limiting post is squeezed, so that the limiting post squeezes the compression spring into the inside of the clamping ring. Since the limiting post is not inside the positioning hole, the limiting effect on the fixed rod inside the clamping ring is no longer achieved. At this time, the fixed rod can be removed from the inside of the clamping ring, achieving the effect of facilitating the disassembly of the installation mechanism.

[0016] (2) By providing the fixed rod in the present utility model, when it is necessary to replace the elastic net, first, the rotating cover is rotated, so that the rotating cover drives the screw rod to rotate inside the threaded tube. At this time, the screw rod drives the push rod to move, so that the extrusion cover outside the push rod no longer positions the elastic net between the connecting plates. At this time, the elastic net can be removed from between the connecting plates. After replacing the new elastic net, by reversing the rotating cover, the screw rod drives the extrusion cover outside the push rod to position the elastic net again, achieving the effect of facilitating the replacement of the elastic net.

Specific Embodiments

[0023] 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 creative efforts shall fall within the protection scope of the present utility model.

[0024] Example 1 Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution:

[0025] A trampoline peripheral protection device includes a trampoline body 1. A support column 2 is fixedly connected to the bottom of the trampoline body 1. An installation mechanism 3 is fixedly connected to the top of the trampoline body 1. A protection mechanism 4 is installed between the installation mechanisms 3. The installation mechanism 3 includes a clamping ring 31. A positioning hole 32 is opened in the inner wall of the clamping ring 31. A fixing rod 33 is installed inside the clamping ring 31. A compression spring 34 is fixedly connected to the outside of the fixing rod 33. A limit post 35 is fixedly connected to the outside of the compression spring 34. A stabilizing rod 36 is fixedly connected to the top of the fixing rod 33. A connecting plate 37 is clamped to the top of the stabilizing rod 36.

[0026] Specifically, as Figure 1 shown, the support columns 2 are symmetrically distributed at the bottom of the trampoline body 1, the clamping rings 31 are symmetrically distributed at the top of the trampoline body 1, the positioning holes 32 are symmetrically distributed in the inner wall of the clamping rings 31, the limiting columns 35 are movably connected to the outside of the fixed rods 33 through compression springs 34, the limiting columns 35 are located inside the positioning holes 32, and the connecting plate 37 is installed on the tops of the two fixed rods 33 through the stabilizing rods 36.

[0027] Furthermore: By symmetrically distributing the support columns 2 at the bottom of the trampoline body 1, the trampoline body 1 can be supported and stabilized. By having the limiting columns 35 located in the positioning holes 32 inside the clamping rings 31, the fixed rods 33 can be installed inside the clamping rings 31. By having the connecting plate 37 located on the tops of the two fixed rods 33, the fixed rods 33 can be kept stable on the top of the trampoline body 1.

[0028] In this implementation: By providing the trampoline body 1, the support columns 2 are fixedly connected to the top of the trampoline body 1, so that the trampoline body 1 is kept stable. When it is necessary to disassemble the installation mechanism 3 on the top of the trampoline body 1, first, the connecting plate 37 is removed from the stabilizing rod 36 on the top of the fixed rod 33, and then the limiting column 35 is squeezed, so that the limiting column 35 squeezes the compression spring 34 into the inside of the clamping ring 31. Since the limiting column 35 is not inside the positioning hole 32, it no longer limits the fixed rod 33 inside the clamping ring 31. At this time, the fixed rod 33 can be removed from the inside of the clamping ring 31, achieving the effect of facilitating the disassembly of the installation mechanism 3.

[0029] Example 2 Please refer to Figure 1 、 Figure 2 and Figure 4 , the difference between this embodiment and Embodiment 1 is that: The protection mechanism 4 includes an adapter plate 41. A threaded pipe 42 is fixedly connected to the outside of the adapter plate 41. A screw rod 43 is threadedly connected to the inside of the threaded pipe 42. A rotary cover 44 is fixedly connected to the outside of the screw rod 43. A push rod 45 is fixedly connected to the end of the screw rod 43 away from the rotary cover 44. An extrusion cover 46 is fixedly connected to the outside of the push rod 45. A elastic net 47 is installed between the adapter plates 41.

[0030] Specifically, as Figures 1-4 shown, the adapter plates 41 are symmetrically distributed on the outside of the fixed rods 33. The screw rod 43 is rotatably connected to the inside of the threaded pipe 42 through the rotary cover 44. The push rod 45 passes through the inside of the adapter plate 41. The extrusion cover 46 is movably connected between the two adapter plates 41 through the push rod 45.

[0031] Furthermore: By rotating the cover 44, the screw 43 is driven to rotate inside the threaded tube 42, so that the screw 43 drives the push rod 45 to move. Through the cooperation of the push rod 45 and the extrusion cover 46, the extrusion cover 46 positions the elastic net 47 between the connecting plates 41.

[0032] In this embodiment: By providing the fixed rod 33, when the elastic net 47 needs to be replaced, first rotate the rotating cover 44 to drive the screw 43 to rotate inside the threaded tube 42. At this time, the screw 43 will drive the push rod 45 to move, so that the extrusion cover 46 outside the push rod 45 no longer positions the elastic net 47 between the connecting plates 41. At this time, the elastic net 47 can be removed from between the connecting plates 41. After replacing the new elastic net 47, by reversing the rotating cover 44, the screw 43 drives the extrusion cover 46 outside the push rod 45 to position the elastic net 47 again, achieving the effect of facilitating the replacement of the elastic net 47.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
