Abstract

The utility model relates to a bicycle single stand. A kickstand seat and a stand are hinged through a pin shaft 4, the kickstand seat is fixed with a safety spring for locking the stand in the erect state, and both ends of a spring 9 are respectively connected to the kickstand seat and the stand. Besides, a sliding block which can be slid in the arc-shaped groove of the kickstand seat is fixed on the stand, and the kickstand seat is also provided with an anchor ear for connecting a cycle frame. The utility model has the advantage of convenient operation; the laying down and the retracting of the stand only need one pushing. The connection strength of the support leg seat and the stand is enhanced, and the durability is high.

Description

Bicycle single stand

The utility model relates to singly keeping a foothold that a kind of bicycle parking uses.

Existing bicycle list is kept a foothold as shown in Figure 4.Its structure is a hinged leg 15 on spike seat 14, a hinged again locking block 16 on the leg.Other has the two ends of a spring 17 to connect respectively and executes pulling force in locking block and spike seat.When parking bicycle, people get earlier with pin leg toward lower plate to erectility (more than 90 degree), and then pull locking block with pin, make the lockhole on the tapered end 18 insertion spike seats 14 on the locking block.Could lock spike like this, bicycle is come to a complete stop; Otherwise, before the bicycle of riding, also pull (opposite) locking block earlier with aforementioned direction, make tapered end on the locking block withdraw from the lockhole of spike seat; Then pulling leg again makes leg forward level attitude to.This shows, all need twice action of operation of singly keeping a foothold in parking and by bike, thereby operation is still terse inadequately.In addition, spike seat and leg have only a hinge-point.Time is long slightly, and the hinged place becomes loose with regard to serious wear, and the angle of inclination when making bicycle parking is strengthened and easily lodging.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the improvement that provides a kind of bicycle list to keep a foothold, this singly keep a foothold should have simple to operate, long-lived characteristics.

The utility model has adopted following technical scheme:

Hinged between spike seat that this is singly kept a foothold and the leg by bearing pin 4.Also fix an insurance spring on the spike seat, this insurance spring locks the leg erectility and uses when bicycle parking.Also fixing bearing pin 11 on the spike seat, the position of this bearing pin is above bearing pin 4; Also fixing on the leg and taking pin 10.There are the two ends of a spring 9 to be connected to bearing pin 11 and to take on the pin 10.

Further specify below in conjunction with embodiment shown in the drawings.

Fig. 1 is that this master who singly keeps a foothold looks scheme drawing.

Fig. 2 is that scheme drawing is looked on its left side.

Fig. 3 is the A-A position cross-sectional schematic among Fig. 2.

Fig. 4 is the prior art scheme drawing.

As shown in the figure, spike seat 1 and leg 8 are hinged by bearing pin 4.Also fixing an insurance spring 6 on the spike seat.This insurance spring and leg all are positioned on the same one side of spike seat.The shape of insurance spring can be by Fig. 2, shown in Figure 3.When leg is pressed, just can push (Fig. 3) locking in the deep-slotted chip breaker that insurance spring enters insurance spring open.If firmly (generally all pushing away with pin) pushes away, also can skid off insurance spring receives to horizontality (during cycling) leg, also fixing bearing pin 11 on the spike seat, also fixing on the leg and taking pin 10, having a spring 9 two ends to connect respectively and execute pulling force at bearing pin 11 with take on the pin 10.As shown in Figure 1, bearing pin 11 is positioned at bearing pin 4 tops.Thereby when leg was packed up (shown in the dotted line) and put down upright two states, the distance of bearing pin 11 and bearing pin 4 was the shortest, and spring 9 has the trend that keeps this two states.

In addition, also as can be known, be shaped on deep-slotted chip breaker on the spike seat among Fig. 1, the center of circle of its arc is on bearing pin 4 axle center.There is a slide block 5 to be embedded in this groove and is fixed on the leg.Because it is outer and greater than the width of this groove that the cap portion of slide block is positioned at groove, thereby slide block can move with leg (when leg was pulled, slide block slided in deep-slotted chip breaker).Neither influence the swing of leg, increased the anchoring strength of spike seat and leg again.Also be shaped on anchor ear 2 on the spike seat.This anchor ear is used for and being connected of cycle frame.Make the spike seat except groove 12 places and bicycle rear axle Bolt Connection, increase this point of attachment of anchor ear again.Fixing for 2 to make the connection of spike seat very firm.At last, decorative protection cover 7 also is equipped with on spring 9 surfaces, can prevent that this spring accident from hurting sb.'s feelings.

It is very convenient that the utility model uses, and leg puts down locking and leg and receives to level attitude and all only need to promote a leg (One Leg Kicking), and is very crisp.Designed slide block structure has increased the linking intensity of spike seat and leg again, makes it durable in use.It is very firm that the anchor ear structure also makes the spike seat connect, and guaranteed the parking quality of bicycle.The existing protective action of trim board also has decorative effect.Thereby this product has good market outlook.
