Abstract

The utility model discloses a varying force arm shockless seesaw, which is mainly technically characterized in that the two ends of a balance plate are respectively provided with a seat which can longitudinally move; the front end of thereof is fixedly provided with corresponding handles; the bottoms of the two ends of the balance plate are respectively provided with an elastic shockless member; the bottom of the movable seat is provided with rolling wheels which are matched with guide rails for the best; the center of the balance plate can also be provided with a balance weight block which can longitudinally move. The utility model has the advantages of scientific and reasonable structure, convenient and flexible use, safety and reliability, small shock and impact force, a comfortable ride, the advantage that the seesaw is driven only through the fact that the self weight and the regulation of a human body change force arms without the need that feet step on the ground, etc.

Description

The variable force arm does not have the shake seesaw

The utility model relates to a kind of recreation body-building sports device, and especially a kind of variable force arm does not have the shake seesaw.

Seesaw is the toy that people just like since ancient times.Seesaw originally mainly is made up of flat board, support, rotating shaft three parts, and the player divides and to be sitting in dull and stereotyped two, rely on both sides with castor stream produce with pedaling make progress active force and both sides' turn of tidal stream is waved in the wind up and down.Since its simple and easy and elegant, seesaw be subjected to deeply people especially children's happiness be subjected to.As everyone knows, need adjust and keep balance during the recreation seesaw, when the human body weight that is sitting in its two differed greatly, seesaw two was just uneven, can not adjust its arm of force again, and seesaw will be swung because of unbalance being difficult to.In addition, this traditional seesaw relies on the human body shank that is sitting in two ends to scrunch ground and swings up and down, not only require great effort but also make feet from injuring easily.And differ greatly in two ends weight, swing up and down and can produce bigger vibrations and percussion to human body when too fast, even insulting brain.

The purpose of this utility model just is to overcome the weak point in the above-mentioned prior art scheme, a kind of scientific structure, reasonable, easy to use, flexible is provided, not only safe but also reliable, only depend on occupant's body weight and regulate the change arm of force and drive, thereby need not that human body is stepped on pedal and vibrations and impulsive force less, the variable force arm of ride comfort does not have the shake seesaw.

The purpose of this utility model realizes by adopting following technical proposal: by bracket supports and the balance plate two ends that connect with rotating shaft the seat that can vertically move is being set respectively, its front end fixedly is equipped with corresponding handle, and the bottom at described balance plate two ends is respectively equipped with the elastic shock attenuation element.In order to obtain better result of use, can also further adopt following technical measures: be provided with the roller that matches with the guide rail installed on the balance plate in described seat bottom, in order to increase the activity performance at seat; The central part that is positioned at balance plate also can be set up the equilibrate counterweight that can vertically move, so that regulate its balance; Above-mentioned elastic shock attenuation element is good with the compression spring.

Accompanying drawing is the structural representation of the utility model embodiment.

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, be placed with the seat 4 of bottom band roller 3 at balance plate 2 two ends of band railing 1 respectively, roller 3 matches with guide rail on the balance plate 2.The central part that is positioned at railing 1 is provided with can be along the equilibrate counterweight 5 of railing 1 move left and right, and seat 4 front portions at its two ends are installed with handle 6 respectively.The bottom, two ends of above-mentioned balance plate 2 is connected with compression shock absorption spring 7 respectively.This balance plate 2 is erected on the bearing 9 by rotating shaft 8.When using the utility model product to travel, can first shifting balance balancing weight 5, eliminate the difference of two ends human body weight, make two of balance plate 2 keep balance and moment to equate.Then, alternately push away mutually or spur corresponding handle 6 by the player, make its seat 4 respectively away from or move forward and backward near handle 6, thereby change length---the moment of balance plate 2 of the arm of force, its poised state is destroyed, begins to swing up and down.By repeatedly, the push-and-pull action that replaces, just can not need scrunching of pin and the Continuous Drive balance plate sticks up and upwarps down.Constantly being compressed, discharging of balance plate 2 two ends bottoms compression shock absorption spring 7 reduced the impulsive force on collision ground on the one hand in addition, increased its upwards power of bounce-back on the other hand again.

The utility model has scientific structure, reasonable, easy to use, flexible, both compared with prior art Safety is again reliable, only depends on body weight and regulate to change the arm of force to drive, and does not need to step on and shake and impact with pedal Power is littler, and the characteristics such as ride comfort are suitable for being placed in various recreation grounds and the kindergarten, can supply juvenile youngster Virgin even the elderly uses.
