Technical Field

The invention belongs to the technical field of playground equipment, and particularly relates to a safety protection type seesaw and a using method thereof.

Background

A seesaw is a toy for children participated by a plurality of people (more than two people). Sit on the seesaw, alone sit one end, go on alone, get off alone, the seesaw principle utilizes lever principle, and the people is power and resistance to the pressure of seesaw, and the distance that the people reaches the fixed point of seesaw is the arm of force respectively, and acceleration of gravity leads to one on the other, and high person acceleration of gravity will be greater than low person, so the high person descends, and the person perks low person under lever principle effect simultaneously, so circulation.

When the seesaw is used, people who ascend to the highest point have upward movement tendency due to the action of inertia, so that the people at the highest point are easy to throw out and fall from a high place, and the safety is low; when a person sitting on the seesaw ascends to the highest point or descends to the lowest point, the seesaw does not have a limiting effect on the person, so that the person can slide down the slope, the person is separated from the seesaw or collides with the handrail, physical discomfort is easily caused to a player, and the use experience of the player is further influenced.

To this end, we propose a safety protection type seesaw to solve the above problems.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a safety protection type seesaw which prevents a slope from slipping and has high safety.

In order to achieve the purpose, the invention adopts the following technical scheme: a safety protection type seesaw comprises a base, wherein the upper end of the base is fixedly connected with a support, the bracket is rotatably connected with a seesaw, the upper sides of the left and right ends of the seesaw are respectively provided with a back protection mechanism and a chest protection mechanism, the two chest protection mechanisms are arranged on the seesaw between the two back protection mechanisms, two chambers are arranged in the seesaw, the side walls at the left end and the right end of the base are respectively provided with an inflating mechanism, the inflating mechanism is communicated with a first air duct and a second air duct, one end of the first air duct far away from the inflating mechanism passes through the bottom and the top of the chamber and is communicated with the back protection mechanism at the same side, one end of the second air duct, which is far away from the inflating mechanism, penetrates through the bottom and the top of the cavity and is communicated with the chest protecting mechanism at the same side, and the upper end of the inflating mechanism is movably connected with the lower end of the seesaw.

In the above safety protection type seesaw, the back protection mechanism comprises a backup plate fixedly connected to the upper end of the seesaw, a first through hole communicated with the side wall is formed in the lower end of the backup plate, a first air bag is fixedly connected to the side wall of one end, close to the chest protection mechanism, of the backup plate, and one end, far away from the inflating mechanism, of the first air duct sequentially penetrates through the bottom and the top surface of the cavity and the first through hole and is communicated with the first air bag.

In the above safety protection type seesaw, the chest protecting mechanism comprises an armrest fixedly connected to the upper end of the seesaw, a second through hole communicated with the side wall is formed in the bottom of the armrest, a second air bag is fixedly connected to the side wall of one end, close to the backup plate, of the armrest, the upper portion of the second air bag is in a C shape, the lower portion of the second air bag is in a strip shape, and one end, far away from the inflating mechanism, of the second air duct sequentially penetrates through the bottom and the top surface of the cavity and the second through hole and is communicated with the second air bag.

In foretell safety protection type seesaw, aerify the mechanism including setting up the recess on the base lateral wall, the bottom and the top surface of recess are fixedly connected with third gasbag and fourth gasbag respectively, third gasbag and fourth gasbag are annular gasbag, third gasbag and first air duct intercommunication set up, fourth gasbag and second air duct intercommunication set up, the top surface of recess is equipped with the logical groove of inside and outside intercommunication, it is equipped with the connecting rod to lead to the inslot activity and run through, the upper end of connecting rod and the lower extreme swing joint of seesaw, the lower extreme fixedly connected with lifter plate of connecting rod, the lifter plate sets up in the recess between third gasbag and the fourth gasbag, the lateral wall of lifter plate and the inner wall sliding connection of recess.

In the safety protection type seesaw, a first sliding groove is vertically formed in the inner wall of the groove, a first sliding block is arranged in the first sliding groove, and the side wall of the first sliding block is fixedly connected with the side wall of the lifting plate.

In the safety protection type seesaw, the lower end of the seesaw is provided with two second sliding grooves, second sliding blocks are arranged in the second sliding grooves, and the lower ends of the second sliding blocks are rotatably connected with the upper ends of the connecting rods.

Compared with the prior art, the safety protection type seesaw has the advantages that:

1. according to the seesaw, the second air bag and the fourth air bag are arranged, when the seesaw rotates, air in the fourth air bag can be extruded into the second air bag, so that the second air bag expands to block shoulders of a person to be tilted through the C-shaped support legs, inertia of the person moving to the highest point can be effectively buffered, the person can be effectively prevented from being thrown out after the seesaw stops suddenly, and the use safety of the seesaw is improved.

2. According to the invention, through the matched use of the first air bag, the second air bag, the third air bag and the fourth air bag, no matter a person using the seesaw ascends or descends, the air in the fourth air bag can be extruded into the second air bag or the air in the fourth air bag can be extruded into the first air bag, the slipping of the person to the direction of the handrail can be effectively buffered through the expansion of the second air bag during ascending, the collision between the chest and the crotch of the person and the handrail can be effectively avoided, the slipping of the person to the direction of the backrest can be effectively buffered through the collision of the first air bag during descending, and then the person sitting astride and the seesaw can be effectively limited through the matched use of the first air bag and the second air bag during ascending and descending, so that the use safety of the seesaw is further improved, the comfort during the use of the device is also improved, and the use experience is further improved.
