The fixing device is characterized in that a sleeve hole is formed on the handlebar folding lower pallet, a groove is formed on the edge to form a clamping ring with elastic deformation, the front fork stem is inserted in the sleeve hole of the handlebar folding lower pallet but is not fully penetrated, a screw rod is arranged in the front fork stem, the screw rod penetrates a pressing filling piece pressed on the surface of the handlebar folding lower pallet to be in threaded connection with a pressing nut, the pressing nut is adjusted to press the head tube headset bearings so as to eliminate the clearance, a bolt hole and a screw are arranged in the position where the groove is arranged on the edge of the handlebar folding lower pallet, and the screw is adjusted to cause elastic deformation of the handlebar folding lower pallet so as to clamp the front fork stem.
Description
Technical field
The utility model relates to the field of captiveing joint between bicycle handle bar and the front fork, particularly captiveing joint between the folding handle bar of folding bicycle and the front fork.
Background technology
The fixed form of existing handlebar folding joint and vertical tube of front fork generally is to protrude a pipe in folding lower adaptor lower end, the end face of pipe is provided with wedge nut, after the pipe that protrudes inserts vertical tube of front fork, up draw folding lower adaptor and vertical tube of front fork wedge nut fastening with stretching screw, vertical tube of front fork is equipped with outward can be with a tight outer nut of tubular axis pressure-bearing, though this fixed form is simple, but being used for the nut that the hold-down head tubular axis holds all is exposed, cause certain defective for the car load outward appearance, reduced class; The outer tubular axis pressure-bearing jack panel without a head of standpipe is also arranged, also without wedge nut, and use " heronsbill sheet " that a tubular axis pressure-bearing is tight, but because the heronsbill sheet is not fixing extremely in standpipe, do not increasing under lower adaptor and the standpipe clamping length situation, be drawn out thereby cause danger when excessive easily when stressed, if and increase the clamping length of lower adaptor and standpipe, tend to increase the volume after folded bicycle folds, out of reach folded bicycle compactness, small and exquisite order ground.
The utility model content
The technical matters that solves:
Be at the fixing defective of present folding joint and vertical tube of front fork order of the present utility model, design the low handlebar folding joint of low, safe, attractive in appearance, the easy processing of a kind of joint height, cost and the anchor fitting of front fork.
The technical scheme of technical solution problem:
The anchor fitting of folding lower adaptor of handlebar and vertical tube of front fork, by the folding lower adaptor of handlebar, head pipe bowl group bearing, vehicle frame head pipe, vertical tube of front fork and fastening parts are formed, head pipe bowl group bearing is equipped with at vehicle frame head pipe two ends, vertical tube of front fork passes the head pipe and head pipe bowl group bearing is connected with the folding lower adaptor of handlebar, it is characterized in that: the folding lower adaptor of handlebar is provided with trepanning and forms the clamp ring of energy elastic deformation at the edge fluting, vertical tube of front fork inserts the trepanning of the folding lower adaptor of handlebar but not exclusively passes, be provided with a screw rod in the vertical tube of front fork, screw rod passes the compress gasket and the hold-down nut that are pressed in the folding lower adaptor surface of handlebar and is spirally connected, regulating hold-down nut can compress head pipe bowl group bearing to eliminate the gap, the folding fluting place, lower adaptor edge of handlebar is provided with screw and screw, and set screw can make the folding lower adaptor of handlebar produce elastic deformation and clamp preceding vertical tube of front fork.
According to actual needs, described compress gasket has to protrude partly to extend in the vertical tube of front fork and cooperates with bore, strengthens the rigidity of vertical tube of front fork with this.
According to actual needs, described vertical tube of front fork runs through the folding lower adaptor of handlebar fully, vertical tube of front fork is provided with outside thread and hold-down nut is spirally connected, and hold-down nut and handlebar also are equipped with pad between the folding lower adaptor surface, and the vertical tube of front fork end can be seals the rigidity that shape strengthens vertical tube of front fork.
Beneficial effect:
Because the vertical tube of front fork inner screw is fixed as one with the vertical tube of front fork inwall, so not only can increase the rigidity of vertical tube of front fork, when also be difficult for being drawn out when being subjected to external force; Can also reach bigger requirement of strength by increasing screw diameter in addition, safe and convenient like this.
