Technical Field

The invention relates to the technical field of teeterboards, in particular to an adjustable teeterboard.

Background

A seesaw is a game tool for children, wherein an upper shaft is arranged in the middle of a long and narrow and thick wood board and then is arranged on a support, people sit at two ends of the wood board and play a game together, and seesaws are arranged in a plurality of parks and playgrounds and are used for attracting children to play and increasing the amount of exercise of the children, so that the children can grow healthily.

The current seesaw is simple in structure and single in function, the capability of adjusting gravity balancing at two ends is not provided, and different children are different in development degree, the body weight is different greatly, when the seesaw is played, heavier people can easily tilt the heavier people and the heavier people are difficult to tilt the lighter people, the heavier people can easily control the seesaw, the playing of the seesaw is out of balance, the fun of the seesaw is greatly reduced, the playing inconvenience is caused, and therefore the adjustable seesaw capable of balancing two ends of the seesaw is needed urgently.

Disclosure of Invention

The invention aims to solve the problem that two persons with large weight difference use a seesaw in the prior art, and provides an adjustable seesaw.

In order to achieve the purpose, the invention adopts the following technical scheme: an adjustable seesaw comprises a base and two buffer seats, wherein the upper end of the base is rotatably connected with the seesaw, the upper end symmetry of wane is fixed with two handles, two spouts, two have been seted up to the lower extreme symmetry of wane the equal sealing sliding connection of inner wall of buffing pad has the push pedal, two the upper end of push pedal all is fixed with the telescopic link, two the upper end of telescopic link all is fixed with a set of pulley, two sets of pulley respectively with the inner wall sliding connection of two spouts, two the interior bottom of buffing pad all is fixed with buffer spring, two buffer spring's upper end all is fixed with and corresponds the sealed sliding connection's of buffing pad inner wall loading board, and the upper end of two loading boards all is fixed with the transmission spring jointly with the bottom that corresponds the push pedal, two the upper portion of buffing pad all is equipped with the balance mechanism, two the lower part of buffing pad all is equipped with speed governing buffer gear.

In foretell adjustable type seesaw, the balancing mechanism is annular oil storage chamber including seting up on buffer base upper portion, the inner wall of oil storage chamber runs through the oil feed tank of seting up with the inside intercommunication of buffer base, the inner wall sliding connection in oil storage chamber has the kickboard, the upper end of kickboard is fixed with the combination magnetic stripe, the inner wall of buffer base runs through to insert and is equipped with the damping cover that two symmetries set up, two the inner wall of damping cover all has the damping plate through connecting spring coupling, the inner wall of buffer base runs through the backward flow groove of seting up a plurality of and the inside intercommunication of oil storage chamber, the upper end of push pedal runs through and has seted up a plurality of upper reaches grooves, oil feed tank and backward flow inslot wall all are fixed with the solenoid valve, be equipped with the check valve.

In foretell adjustable type seesaw, speed governing buffer gear is including seting up the mobile chamber in the buffer seat lower part, the lateral wall in mobile chamber runs through and sets up a plurality of intercommunication grooves with the inside intercommunication of buffer seat, the inner wall in mobile chamber rotates and is connected with a plurality of pivots with a plurality of intercommunication groove one-to-ones, every the circumference lateral wall of pivot all is fixed with commentaries on classics leaf and commentaries on classics cover, every the inner wall of commentaries on classics cover all is fixed with the extension board through reset spring.

Compared with the prior art, the invention has the advantages that:

1. according to the invention, the rocker is limited by the buffer seat and the telescopic rod, so that the rocker can only move up and down within a certain range, and the telescopic rod can play a good role in limiting the left-right shaking of the rocker, thereby reducing the abrasion between the rocker and the base and further prolonging the service life of the rocker;

2. according to the invention, the buffer spring is arranged, so that the rocker can compress the buffer spring when descending, and further, the impact buffering effect is achieved by absorbing energy through the elastic deformation of the buffer spring, the rocker is prevented from being greatly impacted with parts such as the ground in the process of rapidly moving downwards, the vibration at the upper end of the rocker is effectively reduced, and the playing process is more comfortable and safer;

3. according to the invention, when the seesaw tilts too fast, the flow velocity of oil passing through the communicating cavity is fast, so that the stress of the rotating blade is large, the rotating shaft rotates fast, the centrifugal force on the extension plate in the rotating sleeve is large, the extension plate slides to the outside of the rotating sleeve, more space of the communicating groove is occupied, the oil flow in the communicating groove is limited, the oil flow damping is increased, the buffering effect is better and obvious, and the damping magnitude is positively correlated with the tilting speed of the seesaw, so that the safety of a user can be better ensured;

4. according to the weight difference of the two parts, different amounts of oil are stored at the upper end of the push plate, the amount of the residual oil in the oil storage cavity is changed correspondingly, the floating plate drives the combined magnetic strip to change positions correspondingly, so that the extending lengths of the damping plates are different, the damping of the damping plates on the flowing of the oil is different, the oil at the light end is more and the damping is large, the oil at the heavy end is less and the damping is large, the balance of the weight difference of the two parts is realized by adjusting the motion damping at the two ends, and two people with certain weight difference can play better without being influenced.
