Description
Technical field
The utility model relates to a kind of bicycle, specifically belongs to a kind of folding device of Folding Bicycle.
Background technology
Existing Folding Bicycle all is folding device to be housed in front vehicle frame and back between the vehicle frame, and Chinese utility model patent number is 96236535.1, title: multipurpose folding bicycle.The structure of its folding device is made of rotational pin, switch pin and forward and backward fixture block, forward and backward fixture block is " [large and small] " type and mutual fit, the end that forward and backward fixture block is adjacent is hinged by rotational pin, the open end of forward and backward fixture block is provided with switch pin, breach and pin-and-hole, the upper and lower end face of fixture block before breach and pin-and-hole place respectively, the upper and lower side of switch pin is plugged on the upper and lower end face of back fixture block, and switch pin is provided with the bolt of unblanking, and corresponding forward and backward fixture block one side is provided with the hole of unblanking to hold that bears the bolt of unblanking.
There is following shortcoming in the folding device of above-mentioned Folding Bicycle: 1), realize the folding of folding device because above-mentioned folding device is the bolt of unblanking on the toggle switch pin, bolt must stretch out folding device so unblank, user's bolt scratch of being unblanked easily by bike time the like this; Moreover, in the smooth situation of Uneven road, can shake by car body in the time of by bike, the bolt of unblanking has been shaken and the lockhole that gets loose easily, cause the front and back vehicle frame bending of bicycle, the user produces accident.2), folding device is to stir the hole of unblanking to hold that the bolt of unblanking is buckled in forward and backward fixture block one side, makes its folding, such structure is used inconvenient.
The utility model content
The purpose of this utility model is to solve above-mentioned shortcoming, and the folding device of the good Folding Bicycle of a kind of property easy to use, safe is provided.
For achieving the above object: the improvement folding device of Folding Bicycle, between forward and backward vehicle frame, be provided with folding device, described folding device is made of rotational pin, switch pin, retracing spring, handgrip and forward and backward fixture block, described forward and backward fixture block connects forward and backward vehicle frame respectively, one end of forward and backward fixture block is provided with rotational pin and connects, the other end is provided with the switch pin of the forward and backward fixture block activity of lockable, and handgrip is located at the top of switch pin, is with retracing spring on the switch pin between the forward and backward fixture block.
Described handgrip is a draw ring.Switch pin between the described forward and backward fixture block is provided with the bolt of unblanking, and the unblank forward and backward fixture block of bolt position of correspondence is provided with the hole of unblanking to hold that bears the bolt of unblanking.
The beneficial effects of the utility model:
1, the utility model is with retracing spring on the switch pin between the forward and backward fixture block.During the locking of switch pin, the tension force clamping switch pin of spring, prevent to break away from naturally under the switch pin abnormal conditions lockhole, moreover, be with spring on the switch pin, the length of bolt of unblanking reaches to the fixture block side edge surface, can avoid the above-mentioned bolt of unblanking to break away from folding device and the bolt of unblanking by vibrations like this and stretch out folding device and scrape the shortcoming of hurting sb.'s feelings, thereby improve the safety of folding device.
2, the utility model is provided with handgrip on the top of switch pin, and the bolt of unblanking of user's pull-up handgrip rotating switch pin moves to the hole of unblanking to hold of opposite side, realizes unblanking, and brings convenience to use.
