Description
The utility model relates to bicycle, and specifically a kind of have fold mechanism, a bicycle of speed changing force-saving mechanism and band tyre.
The folder function that is had in the existing bicycle, the speed changing force-saving function and exempt to inflate function such as shock-absorbing type wheel be independent all, thereby can't bring into play its allomeric function, secondly used relatively more tired in use locks such as fold mechanism especially still are not easy to carry after folding.
The purpose of this utility model is to design a kind of multi-functional operation bicycle eaily, to overcome above-mentioned defective.
Its main technical schemes comprise be positioned at vehicle frame before, before the back two ends, back vent and chain stay, below front fork, connect front-wheel, back vent connects trailing wheel with the connection part of chain stay, connect the preceding bar of the car that handlebar and brake are installed above the front fork, the top seat bar that has saddle that connects of vehicle frame and back vent contact jaw, chain stay connects the main shaft that sprocket wheel and step are installed with the connection part of vehicle frame, sprocket wheel utilizes chain to connect with ratchet on the hind axle that is installed in trailing wheel, fold mechanism is arranged respectively on the bar before vehicle frame and car, in this fold mechanism, be connected in the associated rod member that is connected with vehicle frame and the preceding bar of car on the two slit bamboo or chopped wood hinge box on the hinge respectively respectively, have on the hinge box can be when two slit bamboo or chopped wood hinge box be closed the lid of fix tightly, in the contact position of back vent and vehicle frame the positioning head that is positioned at the back vent end is arranged, on the vehicle frame at this place, positioning seat is arranged; Be connected with the bolt of extended hinge box on 1 slit bamboo or chopped wood in two slit bamboo or chopped wood hinge box, the nut that lid can be fastened on the hinge box is arranged on the bolt, on nut, be connected with handle; Be connected with flexible positioning head and positioning seat on positioning head and/or the positioning seat; Chain stay and vehicle frame utilize hinge-coupled; But used sprocket wheel is the self-shifting ellipse, on the present bar knock hole that can match with the hole on the vehicle frame is arranged, on vehicle frame, insert place in the pipe of seat bar can damping spring; The handle of being convenient to shake hands is arranged on saddle, on front fork, be connected with front shock absorber; Used front and rear wheel is a band tyre.
The utility model has the advantages that owing to before vehicle frame and car, being provided with folding folding detent mechanism simple in structure on the bar respectively, therefore, during use, only need unclamp nut, unload lower cover, two slit bamboo or chopped wood hinge box just can be separated, make before front fork and the car bar respectively downwards with fold back, more convenient; Secondly, back vent adopts flexible positioning head to contact with positioning seat with vehicle frame, rather than connect, chain stay and vehicle frame are hinge-coupled, therefore, only need vehicle frame is mentioned, just upset downwards is folding, very convenient automatically for trailing wheel: the 3rd, after being provided with handle on the saddle, be convenient to carry car, the seat bar is positioned at the vehicle frame pipe, and just like patent 95239381.6 described spring shock absorptions, when making that with front shock absorber on the front fork this car can adopt non-inflatable solid tyre, still do not have significantly vibrations sensation, the knock hole on the seat bar is used for the compression of seat bar the hole on pin and the vehicle frame being positioned when folding; 4th, behind employing CN2104181U, CN2165090Y, the disclosed laborsaving speedup sprocket wheel of CN2211515Y, make this car have laborsaving and the self-shifting function.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the constitution diagram of trailing wheel after folding.
Fig. 3 is the constitution diagram after all folding.
Fig. 4 is the B-B view of Fig. 5 in the fold mechanism.
Fig. 5 is the A-A view of Fig. 4.
Fig. 6 is back vent and vehicle frame bonding state figure.
As shown in the figure: the front end at vehicle frame (22) utilizes fold mechanism (23) to connect front fork (5), front fork (5) lower end utilizes front axle (7) to connect front-wheel (6), the front fork upper end utilizes fold mechanism (4) connection to have the preceding bar (3) of car of handlebar (1), and brake (2) is installed on handlebar (1).On front fork, also be connected with front shock absorber (8).
The structure of fold mechanism (4) and (23) at hinge (31) but on connect the hinge box (32) of two slit bamboo or chopped wood foldings, and a hinge box (32) therein goes up attachment bolt (29), other has a lid (27) to be enclosed within on this bolt (29), when two hinge box are closed, should cover (27) puts, to cover (27) with the nut (28) of being with handle (30) again and tighten, hinge box is fixed.On two slit bamboo or chopped wood hinge box, can distinguish bar (3) and front fork (5) before connecting frame (22) and front fork (5) or the car.
In the rear end of vehicle frame (22) is the vehicle frame pipe, a bar (18) can be inserted in the top of this vehicle frame pipe, place damping spring between present bar (18) and vehicle frame pipe, present bar upper end connects the saddle (21) that has handle (20), also be distributed with a plurality of knock holees (19) on the present bar, when the contraction of seat bar is folding, pin is inserted the vehicle frame pipe just the seat bar can be fixed with the knock hole on the seat bar.Be connected with main shaft (10) in the lower end of vehicle frame pipe, on main shaft, be connected with oval-shaped force-saving speed-varying sprocket wheel (9) and step (11).
