Description

The seesaw of built-in removable balancing weight

Technical field

The utility model belongs to sports and amusement equipment field, relates to the improvement of seesaw, is a kind of seesaw of built-in removable balancing weight specifically.

Background technology

Traditional seesaw is fixed on the bearing mainly by the balancing pole of a strip, and making the player who is sitting in the balancing pole two ends is that fulcrum just goes up and down to wave with the bearing centring point; But being equal in weight of traditional seesaw fulcrum two ends, the people that only suitable body wt is close uses, otherwise; Balancing pole is just uneven, and the existing technology that can regulate the seesaw balance, as utilizes expansion link to change the distance etc. of seat board and fulcrum; Inconvenient operation; Also destroy the outward appearance of the original symmetrical beauty of seesaw and make a gift of to the greatest extent, how to design the seesaw that a kind of player who keeps the outward appearance symmetry can be fit to different weight again uses, this is the problem that this patent mainly solves.

Summary of the invention

The purpose of the utility model is the problem that exists to prior art, and a kind of seesaw of built-in removable balancing weight is provided, and its reasonable in design is easy and simple to handle, and the player who is fit to different weight uses.

The purpose of the utility model is implemented through following technical scheme: a kind of seesaw of built-in removable balancing weight; Comprise balancing pole, seat board, handrail, bearing, it is characterized in that the built-in removable balancing weight of balancing pole and drive the transmission device of removable balancing weight.

Improvement to technique scheme; Described balancing pole is the pipe shape; Described removable balancing weight is a strip; Described removable balancing weight is processed by metal or armored concrete or the inner pipe of filling sandy soil, and described removable balancing weight Breadth Maximum is less than the internal diameter of balancing pole, and the length of described removable balancing weight is equal to or less than 1/2nd of balancing pole length.

To the further improvement of technique scheme, the back fixation of described removable balancing weight one or two nuts, and described removable balancing weight is respectively being adorned a trundle near the bottom at two ends.

Further improvement to technique scheme; The transmission device of described driving balancing weight comprise shake the hand, gear, screw mandrel, bearing and bearing base; Described shaking the hand is located on the balancing pole under the side handrail; Said handle of shaking the hand can fold, and said rocking bar of shaking the hand vertically inserts in the balancing pole, exposes the lower end of balancing pole inner rocker and is fixing a gear.

To the further improvement of technique scheme, described screw mandrel is processed by high strength steel, and external diameter is no less than one and half; And nut coupling with removable balancing weight back; The smaller polished rod of diameter is left at described screw mandrel two ends, and the external diameter of polished rod equates that with the internal diameter of bearing, gear described screw mandrel revolved the nut at removable balancing weight back; The polished rod place at described screw mandrel two ends respectively is with a bearing; Wherein screw mandrel is close to bearing and is with a gear near the bearing outside of the end of shaking the hand, and gear is fixed with pin with screw mandrel; The said bearing that is enclosed within the screw mandrel two ends by bearing base be fixed on the balancing pole inwall directly over, wherein near the gear of the bearing base of the end of shaking the hand and rocking bar lower end only at a distance from several millimeters.

Further improvement to technique scheme; The axial line of described bearing that fixes and the gear on the screw mandrel overlaps with the axial line of removable balancing weight back nut; With the balancing pole axis parallel; Intersect vertically with the axial line of rocking bar lower end gear, the gear of gear on the described screw mandrel and rocking bar lower end is the intersecting axle gear of one group of tight interlock, and wherein big the and number of teeth of the gear of rocking bar lower end is obviously more than the number of teeth of the gear on the screw mandrel.

Further improvement to technique scheme; Described removable balancing weight back nut equals the distance of removable balancing weight left end to the balancing pole left end to the distance of screw mandrel left end bearing base, and described removable balancing weight back nut equals the distance of removable balancing weight right-hand member to the balancing pole right-hand member to the distance of screw mandrel right-hand member bearing base.

The utility model compared with prior art has many advantages and good effect:

1, the built-in removable balancing weight of the utility model balancing pole, weight contrast that can easy adjustment balancing pole two ends allows two players under the bigger situation of weight difference, normally to use, for the common recreation of father and mother and children and then enhancement emotion provide chance.

2, the utility model is exposed except that shaking the hand of foldable handle of band, and all the other all parts all are hidden in the balancing pole, have kept symmetrical, the succinct outward appearance of traditional seesaw well.

3, the operation of the utility model adjustment is easy safety again, is particularly suitable for old man, child's use.

Description of drawings

Fig. 1 is the structural representation of the seesaw of the built-in removable balancing weight of the utility model;

Fig. 2 is the partial enlarged drawing of C part among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

Referring to Fig. 1 and Fig. 2; A kind of embodiment of seesaw of built-in removable balancing weight comprises balancing pole 3, seat board 1, handrail 2, bearing 4, removable balancing weight 6 and by the transmission device of shaking the hand 5, screw mandrel 11,

gear

9 and 10, bearing 12 and 13,

bearing base

14 and 15 are formed.

Described balancing pole 3 is the pipe shape, is equipped with on the balancing pole 3 under the described right armrest 2 and shakes the

hand

5, and 5 the handle of shaking the hand can fold, and 5 the rocking bar of shaking the hand inserts in the balancing pole 3, and gear 9 is being fixed in the rocking bar lower end.Described removable balancing weight 6 is strip, and Breadth Maximum is less than the internal diameter of balancing pole 3, and length equals the half the of balancing pole 3, and the back fixation of removable balancing weight 6 has the nut 7 supporting with screw mandrel 11, and trundle 8 is equipped with in the bottom at removable balancing weight 6 two ends.
