Technical field
The present invention relates to a kind of seesaw, be specifically related to a kind of body-building seesaw.
Background technology
Seesaw is a kind of common recreational facilities, is placed in park, community and the kindergarten more, and is very popular, and still existing seesaw tilting is up and down played function singleness.
Summary of the invention
The object of the present invention is to provide a kind of body-building seesaw, in amusement, can also reach the purpose of body-building.
To achieve these goals, the technical scheme that the present invention adopts is such: a kind of body-building seesaw comprises that plate body, lower carriage, said plate body middle lower portion and lower carriage are hinged through bearing pin; Said plate body middle upper portion is provided with upper bracket, and said upper bracket top is provided with round open-work, passes mandrel in the said round open-work; Said mandrel both sides are with spring; Said mandrel two ends are provided with handle, and said handle is perpendicular to mandrel, and said handle is connected with mandrel thread through screw.
Further, top, said plate body two ends is fixed with two support plates respectively, and said two support plate inboards are provided with bearing pin, and said bearing pin and sliding sleeve are hinged, and said sliding sleeve is connected with Massage stand, parallel Massage roller and the following Massage roller of being provided with between the said Massage stand.
Further, the both sides of said lower carriage also are provided with foot-driven lever.
Beneficial effect of the present invention: because plate body top is provided with the mandrel that is with spring, the people holds handle when carrying out push-and-pull, and spring force acts on the arm, can temper arm strength; The plate body two ends are provided with messaging backs, and messaging backs is provided with two parallel Massage rollers, when up and down tilting and drawing handle, can massage the back again.Has advantages such as making simple, safety and stability, cost are lower, one-object-many-purposes.

The specific embodiment
To shown in Figure 4, a kind of body-building seesaw comprises that plate body 15, lower carriage 7, said plate body 15 middle lower portion and lower carriage 7 are hinged through bearing pin 6 like Fig. 1; Said plate body 15 middle upper portion are provided with upper bracket 5, and said upper bracket 5 tops are provided with round open-work, pass mandrel 3 in the said round open-work; Said mandrel 3 both sides are with spring 4; Said mandrel 3 two ends are provided with handle 2, and said handle 2 is perpendicular to mandrel 3, and said handle 2 is threaded with mandrel 3 through screw 1.
Top, said plate body 15 two ends is fixed with two support plates 14 respectively, and said two support plates 14 inboards are provided with bearing pin 10, and said bearing pin 10 is hinged with sliding sleeve 11, and said sliding sleeve 11 is connected with Massage stand 9, parallel Massage roller 12 and the following Massage roller 13 of being provided with between the said Massage stand 9.The said Massage roller 12 of going up can roll around self axis with following Massage roller 13.
The both sides of said lower carriage 7 also are provided with foot-driven lever 8.
Two people are sitting in the two ends of plate body 15 respectively, lean against Massage roller 12 and following Massage roller 13, and both feet are placed on the foot-driven lever 8, and both hands are held handle 2, one people pushing handle 2 forward, and another people pulls back handle 2, and at this moment spring force can react on the arm.When pulling back handle 2, the back leans against on Massage roller 12 and the following Massage roller 13, and frictional force makes Massage roller 12 and following Massage roller 13 around self axis rolling, reaches the purpose to back massage.
