Description
[technical field]
The utility model relates to folding bicycle, relates in particular to the device that the car beam to folding bicycle folds.
[background technology]
Usually the body frame structure for automotive of bicycle comprises a fixedly standpipe of vehicle seat, connects the car beam of vehicle seat standpipe and handlebar head, at this moment between car beam and the standpipe at an angle; Integral structure for firm vehicle frame; Usually also need be provided with one and all intersect fixing reinforcement roof beam structure with standpipe and car beam respectively, strengthen roof beam structure, car beam and vehicle seat standpipe formation and stablize on-deformable A-frame structure, keep the stable and load-bearing of car single-piece; In the design of folded bicycle; Usually need on the car beam, can install the bending of car beam additional a folder usually, the car beam is bent.And cooresponding reinforcement roof beam structure above the car beam also must bend thereupon together; Because strengthen roof beam structure is to play to strengthen the vehicle frame bulk strength, bears the position of most weight and stress, under the prerequisite of proof strength; Must accomplish that turning cylinder must overlap fully; It is high that accuracy of manufacture is wanted, and the situation of movement interference can not occur, so also adopt the design plan of folder quite inadequate to strengthening roof beam structure.
In patent 201020246212.5 bicycle car beam reinforced structures; Be to take in the A-frame structure of vehicle frame; Per two bar angles are provided with reinforced rib, then are divided into two sections at the reinforcement roof beam structure, on both involutory surfaces folding joint are installed; Such advantage is to strengthen roof beam structure can shift to reinforced rib and share bearing the part of the force, and splice head part alignment precision, weight capacity of doubling requires to reduce; And its shortcoming also clearly, and most important the considering of folded bicycle optimal design is exactly light weight, convenience, simple, and reinforced rib makes unit design become heavy, has increased the weight of car body weight.
Be divided into two sections and disclose stirrup in the reinforcing mechanisms of the folding head of patent 00260163.X single-beam folding bicycle; Its two corresponding end faces are provided with concave station and the boss that coincide mutually, embed through this concavo-convex cooresponding structure to snap together, and this structural stability is not strong; Can only simply locate; And very high to the positioning accuracy request of structure design, relative position cannot be regulated, thus though this structure design be from intensity, stability or all not ideal enough from precision.
[summary of the invention]
The utility model has proposed a kind ofly can satisfy load bearing stength and require, do not increase car body weight, can conveniently break away from and can stablize and snap together the folding device of strengthening roof beam structure to above problem.
The technical scheme of the utility model is: the reinforcement roof beam structure on folded bicycle; Be divided into two sections of front and back; Be respectively preceding roof beam structure and back roof beam structure; Between the end face of two sections roof beams structure, be provided with and strengthen the roof beam structure folding device, it is characterized in that, said reinforcement roof beam structure folding device comprises preceding plug that is installed in front-axle beam frame end face and the back plug that is installed on the roof beam structure of back; Be provided with on the preceding plug one can and preceding plug between the contiguous block of axial adjustment activity, said contiguous block cooperates through the tapering cylinder and the groove structure location of caving in the back plug.
Through being threaded, distance between the two is through tightening or just unclamping and can regulate between said contiguous block and the preceding plug.
Be connected through nested between said contiguous block and the preceding plug, be provided with between the connecting portion and can let both axially movable springs.
Said contiguous block and back plug be through the tapering cylinder and the groove structure that caves in, and is meant that the back plug processes the cylindrical structure with tapering, and the contiguous block of corresponding back plug then has a groove that caves in that can be stuck on the tapering cylinder.
Said contiguous block and back plug are processed one and are had the tapering cylinder through the tapering cylinder and the groove structure that caves on said contiguous block, then have a groove that caves in that can be stuck on the tapering cylinder on corresponding the back plug of contiguous block.
Has a female cone hole that can be stuck on the tapering cylinder on the plug of said back.
The groove that caves in through slippage between said contiguous block and the back plug is stuck in the tapering circle and goes up and realize that the location is firm.
The beneficial effect of the utility model is: guaranteed the intensity of car beam, employing be very simple fit structure, roof beam structure and back roof beam structure keep the vehicle frame monolithic stability before pinning through tapering and transportable flexible connection piece.Total quality is light, and is simple in structure, safe.

Fig. 1 is the utility model one example structure scheme drawing;
Fig. 2 is the cross-section structure view of this instance.
Wherein: 1, back roof beam structure; 2, back plug; 3, contiguous block; 4, preceding plug; 5, preceding roof beam structure; 6, tapering cylinder; 7, the groove that caves in.
[specific embodiment]
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.
Embodiment 1: the reinforcement roof beam structure on folded bicycle; Be divided into two sections of front and back; Be respectively preceding roof beam structure 5 and back roof beam structure 1; Between the end face of two sections roof beams structure, be provided with and strengthen the roof beam structure folding device, it is characterized in that, said reinforcement roof beam structure folding device comprises preceding plug 4 that is installed in preceding roof beam structure 5 end faces and the back plug 2 that is installed on the roof beam structure 1 of back; Be provided with on the preceding plug 4 one can and preceding plug between the contiguous block 3 of axial adjustment activity, said contiguous block 3 cooperates through the tapering cylinder and the groove structure location of caving in back plug 2.
Through being threaded, distance between the two is through tightening or just unclamping and can regulate between said contiguous block 3 and the preceding plug 4.
