Technical field
The utility model relates to the collapsible exercising apparatus for abdomen that a kind of user's of take self gravitation is resistance.Be applicable to body-building apparatus.
Background technology
The patent No. is the Chinese patent of 201220451459.X, a kind of adjustable exercising apparatus for abdomen is disclosed, comprise underframe, underframe front portion is hinged with chair frame, chair frame top is provided with seat and handrail, the rear portion of chair frame is hinged with rod, the front side of this rod is provided with back cushion, rear side is hinged with connecting rod, the lower end of this connecting rod is hinged on underframe, simultaneously, between the rear portion of chair frame and the rear portion of underframe, be connected with extension spring, the lower end of described connecting rod is hinged on down on " U " shape cutting ferrule, this cutting ferrule and underframe match, simultaneously, on cutting ferrule and underframe, be equipped with locating hole, in this locating hole, is furnished with latch, and the locating hole on underframe is at least 2.Yet this patent structure is complicated, and cost of manufacture is higher, and provide resistance because this patent adopts extension spring, extension spring elasticity variation after repeatedly using, affects result of use.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, the collapsible exercising apparatus for abdomen that a kind of user's of take self gravitation simple in structure, easy to make, lower-cost is resistance is provided, with user's self gravitation, as resistance, train on is good.
The technical scheme that the utility model adopts is: the collapsible exercising apparatus for abdomen that a kind of user's of take self gravitation is resistance, it is characterized in that: comprise rectangular frame, support bar, bearing and base plate, wherein base plate has two, every plate upper surface is provided with two described bearings, each bearing is articulated with respectively one jiao of rectangular frame through support bar, between two bearings on every base plate, through connecting rod I, be connected, between two connecting rod I, through connecting rod II, be connected, seat is installed on rectangular frame, on rectangular frame, one side of seat has cross bar, telescopic chair back mobile jib is rotatably connected on cross bar, the hinged described connecting rod II in this chair back mobile jib lower end.
Described chair back mobile jib comprises hollow sleeve, and the solid hopkinson bar that is plugged in hollow sleeve lower end.
Between described connecting rod I and rectangular frame, be connected to spring.
Described chair back mobile jib both sides are all shaped with row's chair back pole, and chair back pole cover has sponges cover.
Described base plate lower surface is equipped with rubber antiskid pad.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to make, hinged through support bar between rectangular frame and bearing, therefore rectangular frame can move up and down.Can lifting rectangular frame by withstanding chair back mobile jib, thus overcome the acting of user's self gravitation, play the train on of drawing the abdomen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of the utility model stress.
Fig. 3 is the left view of the utility model stress.
The specific embodiment
As shown in Figure 1, the present embodiment is a kind of collapsible exercising apparatus for abdomen that user's self gravitation is resistance of take, comprise rectangular frame 4, support bar 3, bearing 2 and base plate 1, wherein base plate 1 has two, every base plate 1 upper surface is provided with two bearings 2, totally four, each bearing 2 is articulated with respectively 4 one jiaos of rectangular frames through support bar 3.Between two bearings 2 on every base plate 1, through connecting rod I 10, be connected, between two connecting rod I 10, through connecting rod II 11, be connected.Seat 5 is installed on the present embodiment rectangular frame 4, on rectangular frame 4, a side of seat 5 has the cross bar of parallel seat, the telescopic chair back mobile jib 6(that is rotatably connected on cross bar comprises hollow sleeve 601, and the solid hopkinson bar 602 that is plugged in hollow sleeve 601 lower ends), these chair back mobile jib lower end solid hopkinson bar 602 place's articulated linkage II 11.Chair back mobile jib 6 both sides are all shaped with row's chair back pole 7, and chair back pole 7 covers have sponges cover 8.In the present embodiment, at base plate 1 lower surface, rubber antiskid pad is housed.Between connecting rod I 10 and rectangular frame 4, be connected to spring 9.
The concrete using method of the present embodiment is as follows:
User is sitting on seat 5, leans against chair back mobile jib 6, and during beginning, the state of exercising apparatus for abdomen as shown in Figure 1; Then user withstands chair back mobile jib 6 backward with the back of the body, and rectangular frame 4 is stressed rises to position shown in Fig. 2, Fig. 3, and gravity acting, plays the effect of drawing the abdomen.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
