Description

[0001] The present invention relates to the technical field of trampolines, in particular to a safer trampoline.

[0002] A trampoline is a resilient piece of exercise equipment, shaped like a bed and consisting of a rectangular "bed" made of woven synthetic fibers and steel springs. The trampoline's resilience is achieved by the steel springs that hold the bed to the frame and allow the athlete to utilize the bounce to perform various movements. However, when children use conventional trampolines, there is a risk of losing balance or adopting an incorrect posture, which can lead to bruised wrists and ankles or even broken bones, so there is an urgent need for a safer trampoline.

[0003] Conventional trampolines have the following serious safety deficiencies: They cannot prevent the support bars from collapsing, which leads to the risk of accidents, and they do not offer children a sufficiently protected jumping surface. They do not have an automatic leveling device to ensure that the jumping mat is always horizontal on uneven surfaces.

[0004] The object of the present invention is to provide a safer trampoline that solves the problems of conventional models identified in the prior art: the inability to prevent accidents caused by the collapse of support bars, the lack of a sufficiently safe jumping environment for children, and the inability to quickly adapt to uneven surfaces while ensuring a level jumping surface.

[0005] To achieve the above object, this invention provides the following technical solution: A safer trampoline comprising a support steel frame, at the bottom of the support steel frame there is arranged a protection unit comprising an airbag, the airbag being connected and fixed to the support steel frame by means of a provided fixing rod, the air inlet port of the airbag being connected to one end of an air duct, and the other end of the air duct being connected to the air outlet port of an air pump, the air pump being connected and fixed to the fixing rod by means of an adjusted T-beam, the bottom of the support steel frame being connected to one end of a hydraulic push rod which is evenly distributed, and the other end of the hydraulic push rod being connected to the upper end of the foot part.

[0006] Preferably, a jumping mat is provided above the airbag, wherein the outer wall of the bottom of the jumping mat is provided with evenly distributed triangular snap fasteners, the upper inner wall of the supporting steel frame is provided with curved snap fasteners, wherein the supporting steel frame is provided with springs by means of curved snap fasteners which cooperate with the triangular snap fasteners to firmly connect the jumping mat, wherein the upper side of the jumping mat is equipped with a safety net.

[0007] Preferably, a zipper adapted to the bottom of the safety net is provided, and a uniformly arranged support bar is provided on the upper part of the support steel frame, wherein vertically arranged locking holes are provided on one side of the support bar.

[0008] Preferably, the inner wall of the support rod is connected to a movement rod adapted thereto, wherein the movement rod engages with the locking holes by means of an elastic push button and is thus connected and fixed to the support rod.

[0009] Preferably, the top of the movement rod is connected to one end of a support rod.

[0010] Preferably, the inner wall of the other end of the support rod is connected to the outer wall of a snap ring adapted thereto.

[0011] Preferably, the inner wall of the upper part of the safety net is connected to the outer wall of the snap ring.

[0012] Compared with the prior art, this invention has the following advantageous effects: 1. The safer trampoline features a cross-bar attachment, which serves to evenly distribute the pressure of the airbag across the supporting steel frame to avoid local overloads and thus increase the overall safety and stability of the trampoline. The airbag is inflated by operating the air pump, quickly reaching the required air pressure.The inflated airbag can effectively disperse and absorb the impact forces generated by children jumping, reducing the load on the lower support bars of the support steel frame to prevent accidents caused by bar breakage; in addition, the provided hydraulic push bar plays a key role in creating a safe jumping environment for children by automatically adapting to uneven surfaces and thus always ensuring a level jumping surface; the special claw-shaped footboard enlarges the contact area and thus significantly increases grip, effectively preventing the trampoline from slipping or sliding. 2. The safer trampoline uses a combination of safety net and support bars, which effectively catches users who lose control or stray from the jumping area and prevents falls. The elastic snap button on the adjustable movement bar allows the safety net height to be continuously adjusted, allowing age-appropriate use from toddlers to teenagers, thus meeting the different needs of toddlers and teenagers and extending the life cycle of the trampoline.

[0013] As in Fig.As shown in Figures 1 to 4, this invention offers a technical solution: a safer trampoline comprising a supporting steel frame 1, wherein a protection unit 2 comprising an airbag 201 is arranged at the bottom of the supporting steel frame 1, wherein the airbag 201 is connected and fixed to the supporting steel frame 1 by means of a provided fixing rod 202, wherein the air inlet opening of the airbag 201 is connected to one end of an air line 203, and the other end of the air line 203 is connected to the air outlet opening of an air pump 204, wherein the air pump 204 is connected and fixed to the fixing rod 202 by means of an adjusted T-beam 205, the bottom of the supporting steel frame 1 is connected to one end of a hydraulic push rod 3 which is evenly distributed, and the other end of the hydraulic push rod 3 is connected to the upper end of the foot part 4, wherein a jumping mat 5 is provided above the airbag 201,The outer wall of the bottom of the jumping mat 5 is provided with evenly distributed triangular snap fasteners 6. The upper inner wall of the supporting steel frame 1 is provided with curved snap fasteners 7. The supporting steel frame 1 is provided with springs 8 by means of curved snap fasteners 7, which cooperate with the triangular snap fasteners 6 to firmly connect the jumping mat 5. In addition, the cross-mounting rod 202 serves to evenly distribute the pressure of the airbag 201 across the supporting steel frame 1 to prevent local overloads and thus increase the overall safety and stability of the trampoline. The airbag 201 is inflated by the operation of the air pump 204, quickly reaching the required air pressure for the airbag 201. The inflated airbag 201 can effectively distribute and absorb the impact forces generated by children jumping.This reduces the load on the lower support struts of the support steel frame 1, preventing accidents caused by strut breakage. Furthermore, the hydraulic push bar 3 contributes significantly to creating a safe jumping environment for children by automatically adapting to uneven surfaces and thus always ensuring a level jumping surface. The special claw-shaped foot section 4 enlarges the contact surface and thus significantly increases grip, effectively preventing the trampoline from slipping or sliding.
