Problems solved by technology

[0003] However, the common trampoline currently on the market has the following problems: (1) the elastic range is small, the impact force on the human body is large, and the shock absorption function is backward; (2) the guardrail structure is stiff, the bearing capacity is small, and the bouncing effect is not good; (3) Lack of vocal music devices for electronic competitions, low entertainment
[0005] In order to solve the problems of stiff guardrail structure, small bearing capacity and poor bouncing effect, the invention patent CN201105113Y discloses a trampoline fence structure

Embodiment 1

[0020] The guardrail cushions the trampoline, including a bed body frame, a jumping cloth 7 and a protective net 1. The bed body frame includes a frame I 8 arranged horizontally, a frame II 5 and a guardrail 2 arranged vertically. Frame I 8 is arranged at the bottom and said frame II 5 is arranged at the top. The jumping cloth 7 is connected with the frame I 8 by the spring 9, and the spring 9 between the jumping cloth 7 and the frame I 8 is covered with a buffer pad. The bottom of protective net 1 links to each other with jumping cloth 7, and the top of protective net 2 and frame II 5. Guardrail 2 comprises upper guardrail, lower guardrail, buffer body 20 and bearing pin 21, and the bottom end of upper guardrail and the top of lower guardrail are square tubes, and are all provided with the through hole that matches with bearing pin 21, and buffer body 20 is enclosed within The outer side of pin shaft 21. The upper guardrail and the lower guardrail are connected by the pin s...

Embodiment 2

[0022] Different from Embodiment 1, the guardrail 2 includes an upper guardrail and a lower guardrail, and a buffer device 3 is provided on the guardrail 2 . Buffer device 3 comprises upper connector 18, lower connector 19, buffer body 20 and bearing pin 21, and the bottom end of upper connector 18 and the top end of lower connector 19 are all provided with the through hole that matches pin 21, buffer body 20 sleeves on the outside of bearing pin 21. The upper connector 18 is arranged at the bottom of the upper guardrail, and the lower connector 19 is arranged at the top of the lower guardrail. An opening is provided on the side of the connecting portion of the upper connecting piece 18 and the lower connecting piece 19 facing the protective net 1 , and the central angle corresponding to the opening is 160°. The buffer body is elastic rubber, and the upper connecting piece 18 and the lower connecting piece 19 are circular tubes.

Embodiment 3

[0024] The difference from Embodiment 1 is that the bed frame also includes a booster shock absorber 4, and the booster shock absorber 4 includes a bed connecting sleeve 10, a booster connecting sleeve 11, a guardrail connecting sleeve 12 and a support connecting sleeve. Station pipe 13, bed connecting sleeve 10 is connected with frame 18 to form bed body, and guardrail connecting sleeve 12 is connected with guardrail 2 to form protective mechanism. The bed connecting sleeve 10, the booster connecting sleeve 11 and the guardrail connecting sleeve 12 are fixedly connected to form a five-way structure, the bed connecting sleeve 10 is perpendicular to the booster connecting sleeve 11, the guardrail connecting sleeve 12 is connected to the auxiliary The pusher connects the sleeve pipe 11 in parallel. The booster connection sleeve 11 communicates with the support connection station pipe 13 through an elastic device, and the support connection station pipe 13 is connected with the f...

Abstract

The invention discloses a guardrail buffer trampoline which comprises an upper guardrail and a lower guardrail, wherein a buffer device is arranged on each guardrail; the buffer device comprises an upper connecting piece, a lower connecting piece, a buffer body and a pin shaft; through holes matched with the pin shaft are formed in the bottom end of the upper connecting piece and the top end of the lower connecting piece; the buffer body is arranged on the outer side of the pin shaft in a sleeving manner; the upper connecting piece is arranged at the bottom end of the upper guardrail; the lower connecting piece is arranged on the top end of the lower guardrail; an opening is formed in one side, which faces a protective net, of a connecting part of the upper connecting piece and the lower connecting piece; and a central angle which corresponds to the opening is 100-160 degrees. The buffer body is inserted through the pin shaft, the upper guardrail and the lower guardrail are connected to form a guardrail buffering mechanism, the effect of buffering and preventing collision with the guardrails in the process of using the trampoline by a human body is achieved, the impact force of the human body is reduced, injury of the human body is reduced, a better safe and protective effect is achieved, and the service life of the trampoline guardrail is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fitness and entertainment facilities, and in particular relates to a trampoline with a guardrail buffer mechanism. Background technique [0002] The trampoline is a kind of sports equipment that helps to train the body's sense of balance, reaction ability, dynamic vision, and muscle softness. At the same time, the moderate vibration of its bouncing motion helps the brain development of young people; A recreational activity suitable for all ages. A conventional trampoline basically consists of the following parts: a jumping cloth, a trampoline frame, an elastic assembly connecting the jumping cloth and the trampoline frame, a protective cover covering part of the trampoline frame and the elastic assembly, and a foot assembly connected to the trampoline . For an added safety factor, some trampolines also include safety nets to prevent the user from falling off the trampoline during use. [0003] However,...
