Description

A kind of Folding Bicycle

The utility model relates to a kind of Foldable bicycle.

Relevant by retrieval patent documentation does not retrieve the Foldable bicycle identical with the utility model structure at present as yet.Existing Foldable bicycle kind is more, differs from one another.ZL96204537.3, name is called " multifunctional foldable bicycle ", disclose and a kind ofly front wheel carrier and rear wheel frame have been fixed together to connect steady arm, reach a kind of Folding Bicycle of folding purpose, though this patent has folding convenient, can be used as characteristics such as hand barrow use, but since tap etc. locate to fail to be folded, so the volume after folding is still bigger.And because the width of tap is a fixed value, so be difficult to satisfy all ages and classes personnel's requirement by bike.

The purpose of this utility model be to provide a kind of have folding freely, and can make a kind of Folding Bicycle that width, height adjustment are convenient to travel and are carried.

Technical characterictic of the present utility model is: on the basis of considering safety and comfort, folding convenient, be designed to a kind of Folding Bicycle of forming by front fork part, tap, vehicle frame, vehicle seat, regulating control, back vent part, pedal, anchor fitting, it is characterized in that: described tap is made up of handlebar, handlebar regulating control, bend pipe, bend pipe compact heap, leading vertical tube, leading regulating control, described handlebar is packed in the two ends of bend pipe by the handlebar regulating control, and described bend pipe is packed on the leading vertical tube by the bend pipe compact heap; Tap vertical tube skewer is contained on the vehicle frame, and regulates fixing by leading regulating control; Described vehicle frame is made up of front vehicle frame, unitor, back vehicle frame, and unitor folds front vehicle frame, back vehicle frame and fix; Described vehicle seat skewer is contained on the vehicle frame, and clamps by regulating control; Regulating control is arranged on the inclined tube of back vehicle frame; Described anchor fitting one end is arranged on the front vehicle frame, and the other end is arranged on the vehicle frame of back.

Handlebar regulating control in the described tap by stationary pipes, regulate bolt, movable voussoir, termination and form, stationary pipes is fixed on the handlebar in the tap; The splay end of stationary pipes contacts with the skewed surface of movable voussoir, and makes movable voussoir generation slippage by regulating bolt, and it is solid in the inner chamber of bend pipe that stationary pipes, movable voussoir are expanded.

Unitor in the described vehicle frame is made up of preceding Connection Block, locating dowel pin, removable pin, shift fork, spring, back Connection Block, and preceding Connection Block links to each other with front vehicle frame; Back Connection Block links to each other with the back vehicle frame, and locating dowel pin is hinged together preceding Connection Block, back Connection Block, makes preceding Connection Block, back Connection Block along the locating dowel pin axial rotation; On preceding Connection Block, be provided with a tiltedly seat hole face A; Be provided with the corresponding oblique seat hole face B with oblique seat hole face A on shift fork, shift fork is packed on the removable pin, is provided with spring on removable pin; Also can make axial rotation on the Connection Block before removable pin is arranged on, on removable pin, be provided with a cross section C, on the Connection Block of back, be provided with an open slot D and a knock hole E who matches with removable pin cross section C.

Described regulating control is made up of clamp shaft, handle, spring, guide finger, but clamp shaft is provided with the hole F of a skewer dress handle button; Be fixed with guide finger on the clamp shaft, on handle, be set with spring; Negative winding stem at handle is provided with groove G and the back stop slot H that matches with guide finger.

During use, open the anchor fitting that is arranged on the vehicle frame, the forward and backward vehicle frame of drawing close at ordinary times is stretching.Under the effect of the unitor in vehicle frame, preceding Connection Block rotates along locating dowel pin with the back Connection Block, make the cross section C of removable pin and the open slot D interlock on the Connection Block of back, the shift fork of stirring in the unitor makes removable pin make axial rotation, under the effect of oblique seat hole face A and spring on the preceding Connection Block, removable pin moves axially simultaneously, and with the spindle nose skewer go into to the back Connection Block knock hole E in, this moment is under the effect of spring, oblique seat hole face B on the shift fork engages with oblique hole face A on the preceding Connection Block, because the open slot D on the Connection Block of back is less than the diameter of removable pin, when the cross section C on the removable pin enters the knock hole rotation by open slot D after, thereby before inciting somebody to action, back vehicle frame is locked.Whether the handle that takes out again in the regulating control is gone into leading regulating control in the tap with the button skewer of handle, regulate the height of leading vertical tube and align with front-wheel, and it is fixed.The bolt of regulating on the bend pipe compact heap with handle compresses bend pipe again.The position that regulates handlebar again adapts the width of handlebar and rider's arm developed width.Regulate bolt with handle again, make movable voussoir move axially and make its angled end-face to contact, thereby swelling is fixed on the end of bend pipe with the splay end of stationary pipes; Can drive and ride this moment.When needs are folding, respectively the handlebar regulating control on the tap, bend pipe compact heap, leading regulating control, regulating control are unclamped with handle, and close up, rotate the shift fork of unitor on the vehicle frame again, shift fork moves axially along the oblique seat hole face A of preceding Connection Block when rotating, thereby makes the end of removable pin withdraw from afterwards the knock hole D of Connection Block, folding stand again, cross section C on the removable pin separates with the open slot C of back on the Connection Block, and forward and backward wheel is drawn close.Under the effect of anchor fitting, front vehicle frame, back vehicle frame are fixed.The folding of bicycle volume is dwindled greatly.Usual handle skewer is contained in the regulating control on the clamp shaft, and the spring on the handle is provided with for preventing the handle loose or dislocation.

The utility model has the advantages that: because the height of handlebar, the direction of bend pipe in the tap, leading vertical tube all can adjust, thereby make bicycle rider more comfortable, freely, and can satisfy all ages and classes people's driving; Because Vehicle Frame Design becomes forward and backward two-section, easy to operate, connection reliable functioning that unitor has, thus make the whole operation simple and fast; Because the handle in the regulating control has multi-edged function, thereby makes swift to operate, safety; Because compact overall structure is reasonable, easy to use, so very big practical and popularizing value is arranged.
