Abstract

The utility model relates to a double-hinged laborsaving main support of a motorcycle, and comprises a main bed frame (6) with two stand bars, and a lateral support (7) which is formed into an integrated body with the main bed frame. The utility model is characterized in that the lower ends of the two stand bars of the main bed frame are provided with a foldable standpipe (3) which is hinged with the stand bars, a moveable closing piece (2) is arranged in the foldable standpipe, a spring (8) is sleeved on the moveable closing piece, the top of the standpipe is propped up to the lower end surfaces of the two stand bars of the main bed frame, or an opening which can lead the closing piece to be extended out and propped up to the lower end surfaces of the stand bars of the main bed frame is provided, and a mechanism which can lead the standpipe to be elastically reset is installed at the hinged position of the main bed frame and the foldable stand-pipe. Compared with the prior art, the hinge mode is adopted by the utility model for changing the standpipe to be foldable type, thereby achieving to lower the height of the support and satisfying the laborsaving purpose. When the standing position is reached by the foldable standpipe, the built-in closing piece is automatically locked under the gravity, thereby guaranteeing safety and steadiness when in standing.

Description

The laborsaving main support of motor bike double-strand chain formula

(1), technical field

The utility model relates to motorcycle main support, the laborsaving main support of particularly a kind of motor bike double-strand chain formula.

(2), technical background

In recent years, the structure of motorcycle main support has had bigger improvement, after the laborsaving main support of rack-and-pinion, has occurred the laborsaving main support of a kind of simple chain formula again.This main support is owing to cut in two axle sleeve, make axle shorten with the effective length that cooperates of axle sleeve, to cause support when stressed, to occur rocking, when the wigwag motion vehicle body, reversing of relative position partly will take place in two of this main support, when being torqued into the certain angle position, main support will be regained under the spring tension effect, car can not be come to a complete stop, serious reversing phenomenon takes place, bring serious hidden danger to safety.In addition main support by the centre vertically in two after, self intensity reduces greatly, makes fastness, overload will be subjected to great restriction.

(3), Fa Ming content

Technical problem to be solved in the utility model is: a kind of simple in structure, control comfort and good stability, the laborsaving main support of motor bike double-strand chain formula that safety economy is durable are provided.

Technical problem to be solved in the utility model is to realize by such technical scheme: the laborsaving main support of promptly a kind of motor bike double-strand chain formula, the main pedestal that comprises the two legs of band reaches the side stand of one with it, it is characterized in that: but two legs lower end of main pedestal has and its pivotally attached folding up pipe, but has movable lock dog in the folding up pipe, support by spring between movable lock dog and the standpipe, the top of standpipe withstands on the two leg lower surfaces of main pedestal, or has the hole that lock dog is stretched out and withstand on the two leg lower surfaces of main pedestal; But the hinged place at main pedestal and folding up pipe is equipped with the mechanism that makes the standpipe elastic reset.

The utlity model has following advantage:

1, to adopt hinge that standpipe is become folding for the utility model, reduces station frame height to reach, and satisfies laborsaving this purpose.

2, when but the folding up pipe arrives assigned position, built-in lock dog is locking voluntarily under the effect of gravity, reaches the effect of insurance, to satisfy this performance of safety.

3, the axle sleeve from a top of the trellis is an integral body to hinge, has satisfied this requirement of fastness.

(4), the description of the drawings

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 partly cuts open scheme drawing for the local amplification of accompanying drawing 1 office.

Referring to accompanying drawing: among the figure: but 2-lock dog, 3-folding up pipe, 4-hinge axis, 5-retracing spring, 6-main pedestal, 7-side stand, 8-spring.

(5), specific embodiment

The utility model is described in further detail in conjunction with the accompanying drawings and embodiments more below.

Referring to Fig. 1,2, the laborsaving main support of motor bike double-strand chain formula among the figure, the main pedestal 6 that comprises the two legs of band reaches the side stand 7 of one with it, it is characterized in that: but two legs lower end of main pedestal has and its pivotally attached folding up pipe 3, but has movable lock dog 2 in the folding up pipe, be with spring 8 on the movable lock dog, the top of standpipe withstands on the two leg lower surfaces of main pedestal, or has the hole that lock dog is stretched out and withstand on the two leg lower surfaces of main pedestal; But the hinged place at main pedestal and folding up pipe is equipped with the mechanism that makes the standpipe elastic reset.

In the embodiment that accompanying drawing provides, the upper end of movable lock dog is with spring 8, and the top of standpipe 3 has the hole that lock dog is stretched out and withstand on the two leg lower surfaces of main pedestal; 6 pairs of leg lower surfaces of main pedestal have the groove that lock dog is inserted.

In said structure, but be made of the torsion spring 4 that is contained on the jointed shaft 4 in the mechanism that makes the standpipe elastic reset of main pedestal 6 with the hinged place installation of folding up pipe 3, wherein an end of torsion spring is connected on main pedestal 6 or the side stand, and the other end is connected on the standpipe 3.

Working process of the present utility model is such: when main support is in position shown in Figure 1, with pedal side stand 7, but angle of folding up pipe 3 and matrix 6 foldings, when main support reaches the standing place, deflection left, this moment, side stand 7 contacted with ground, make motor bike be in the side holding state, simultaneously, but the right folding up pipe 3 breaks away from ground-surface restriction, under the effect of retracing spring 5, reset to assigned position voluntarily.Car pushed away to the upper right side carries, but the right folding up pipe 3 lock dog 2 is pinned automatically by deadweight with after ground contacts, the same by gravity pinning in the left side, at this moment, primary stand is in the car body holding state.In the time will driving a vehicle, car is pushed away forward, this main support is recovered to the road location under the extension spring effect, and lock dog 2 is removed locking state under the effect of spring 8.

Claims

1, the laborsaving main support of a kind of motor bike double-strand chain formula, the main pedestal (6) that comprises the two legs of band reaches the side stand of one (7) with it, it is characterized in that: but two legs lower end of main pedestal has and its pivotally attached folding up pipe (3), but has movable lock dog (2) in the folding up pipe, be with spring (8) on the movable lock dog, the top of standpipe withstands on the two leg lower surfaces of main pedestal, or has the hole that lock dog is stretched out and withstand on the two leg lower surfaces of main pedestal; But the hinged place at main pedestal and folding up pipe is equipped with the mechanism that makes the standpipe elastic reset.
