Description

A kind of bicycle folding umbrella canopy support frame

The utility model relates to a kind of collapsible umbrella canopy support frame that is used on the bicycle.

China is a bicycle big country, most people all with bicycle as main walking-replacing tool, but because the restriction of bicycle structure, run into that burning sun is exposed to the sun and rainy weather, people or hold up an umbrella by bike perhaps wear raincoat by bike, bring great inconvenience to trip.

The purpose of this utility model can be fixed on the bicycle in order to provide a kind of exactly, detachable and folding of bicycle umbrella canopy support frame, utilize it to set up the umbrella paulin, energy invasion and attack of rain cover and being exposed to the sun of burning sun, and do not block cyclist's sight line when using, need not be hand steered, do not increase the occupation of land scope of bicycle.

The purpose of this utility model is achieved in that the chassis with support is fixed on the back shelf of bicycle, the pulling pull bar is under the drive of gangbar, and the umbrella paulin launches automatically and tightens, the diagonal ligament of leaving behind, can just prop whole umbrella canopy support frame, just can play the effect of sun-shading rain-proof.

The collapsible umbrella canopy support frame that uses the utility model to provide can be as the bicycle part of the whole, and also detachable bicycle is easy to carry.This utility model is of a tightly knit structure, and is simple to operate, safe and practical, light, improved the defective on bicycle structure and the function, for common people provide very big convenience.

Below in conjunction with accompanying drawing preferred forms of the present utility model is described in detail:

Fig. 1 is a scheme drawing of the present utility model.

Fig. 2 is a front elevation of the present utility model.

Fig. 3 is a support zone right elevation of the present utility model.

Fig. 4 is a connection of the present utility model position right elevation.

Fig. 5 looks and birds-eye view for the vertical keel of umbrella paulin of the present utility model, the horizontal keel right side.

Fig. 6 is that horizontal keel of the present utility model connect the joint constructional drawing.

Fig. 7 is vertical keel four bar structure interface charts of the present utility model.

As Fig. 1, the bicycle umbrella canopy support frame is fixed on behind the bicycle on the shelf by base (1).As Fig. 2, the lower end of Fig. 3 two vertical rods (2) and mutually attached two pull bars (3) is hinged with base (1) respectively.By spring bayonet socket (12) location, stay cord (16) traction is arranged between two vertical rods (2) as two vertical rods of Fig. 2 (2), do lacing wire.Fig. 3, vertical rod (5) lower end links to each other with the upper end of link piece (4) with vertical rod (2) and pull bar (3) by gangbar (13).Pulling pull bar (3) drives raising up of vertical rod (5) by gangbar (13) and link piece (4), owing to the location of spring bayonet socket (12) to vertical rod (2), thereby has determined the angle that raises up of vertical rod (5).As Fig. 2, can roll over crossbeam (6) and strut automatically by spring pulling function.As Fig. 4, drive the horizontal spreading of umbrella paulin frame (9) by steering swivel (8).As Fig. 5, lateral keel (11) is launched with the expansion of seeing umbrella paulin frame (9) by keel steering swivel (14), thereby drive the stretching, extension of vertical keel (10), the structural hook of parallel four-bar (15) auto lock under the effect of torsion spring (17) between vertical keel (10) is tightened longitudinal and transverse keel and is overarched so that drop down rainwater.Prop up the overall process of propping that diagonal ligament (7) is then finished the umbrella paulin as Fig. 4, just bicycle possesses the function of sun-shading rain-proof.
