Description

Bicycle pearl bowl group Fastening device

Technical field

The utility model relates to a kind of bicycle pearl bowl group Fastening device.

Background technology

The front-wheel of Regular Bicycle mainly in order to control bicycle balance and turn to, so the front-wheel of bicycle and connection between the handle basically, main vehicle head tube place at vehicle frame, constitute the rotating shaft (being front fork vertical bar) of front fork and the connection between the handle, in the hope of when bicycle handle turns to, can allow front-wheel along with handle and front fork swing, reach the purpose that turns to smoothly and control balance.

As shown in Figure 1, be the front fork and the handle coupling arrangement scheme drawing of prior art; Wherein, bicycle is provided with a front fork vertical bar 11 of passing vehicle head tube 12 in the top of its front fork (not indicating among the figure), the end section that this front fork vertical bar 11 passes vehicle head tube 12 relatively mainly engages for the locking block 21 of leader's standpipe 2, this stem 2 corresponds to other end that is provided with locking block 21 and supplies assembling handle 4, therefore constitutes the connection of handle 4 and front fork vertical bar 11 (that is rotating shaft of front fork).In addition, these vehicle head tube 12 places are provided with a pearl bowl group that mainly is made of upper and

lower pearl dish

31,32 and spiro connecting piece 33, plug 34; Wherein, upper and

lower pearl dish

31,32 places the upper and lower end of vehicle head tube 12 respectively; Spiro connecting piece 33 places the inner ring of front fork vertical bar 11, as for plug 34 be pass locking block 21 tops again with spiro connecting piece 33 bolts, under the state that plug 34 and spiro connecting piece 33 screw, locking block 21 gets final product upper and

lower pearl dish

31,32 of downward packing and vehicle head tube 12, and this locking block 21 is a fixture block 211, further utilize fixture block 211 with locking block 21 clippings in front fork vertical bar 11 outsides, strengthen the connection effect between handle and the front fork, and allow and normally relatively rotated between front fork vertical bar 11 and the vehicle head tube 12.

Yet, directly stem 2 is installed on the front fork vertical bar 11, and locking block 21 also directly overlays the tail end in front fork vertical bar 11, therefore can't change the height and position of stem, that is the bicycle of same size can be because the difference of rider's stature think that handling position is too high or too short, and then causes using the restriction of object.

The utility model content

Technical problem to be solved in the utility model is: bicycle pearl bowl group Fastening device is provided, and it also can cooperate the height and position that changes the handle height, with the user demand in response to different riders except can constituting the connection of handle and front fork really.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: bicycle pearl bowl group Fastening device, it is provided with a front fork vertical bar of passing vehicle head tube above bicycle front fork, it includes pearl dish, following pearl dish, spiro connecting piece, extension vertical tube, bundle son and plug, wherein, described upward pearl dish places the upper end of vehicle head tube; The described dish of pearl down places the lower end of vehicle head tube; Described spiro connecting piece places the inner ring of front fork vertical bar, in order to form urgent effect with front fork vertical bar; Described extension vertical tube is equipped on the top of pearl dish, and its top is for the installing stem, and the bottom supplies to socket-connect with front fork vertical bar, and is provided with plug perforation on its top; The young corresponding socket place that extends vertical tube and front fork vertical bar that is provided in of described bundle clamps in order to will extend vertical tube and front fork vertical bar; Described plug penetrate extend vertical tube the plug perforation again with the spiro connecting piece bolt of front fork vertical bar inner ring.

Described bundle son vertically is provided with two folder ears, between two folder ears, be provided with slot one, and be respectively equipped with at least one group of corresponding screw perforation and screw hole on the ears in two folders, available screw is worn between lock and the two folder ears, will extend the clamping of vertical tube and front fork vertical bar.

Described extension vertical tube bottom corresponds to the zone of establishing for the young folder of bundle and is provided with long slot bore one.

Described spiro connecting piece is provided with screw and is spirally connected for plug.

The beneficial effects of the utility model are:

1) utilizes the mode of plug and spiro connecting piece bolt will extend up pearl dish place packing of vertical tube, can organize urgent device by the whole pearl bowl of packing, make it be fixed in front fork vertical bar, reach the purpose that certain formation handle and front fork connect.

2) the young tight bundle of utilization bundle corresponds to the position of pearl dish end face in extension montant outer ring, and has long slot bore one because of extending montant, utilized the bundle son to come this long slot bore of packing, can allow the extension montant be anchored on the front fork vertical bar, make between front fork vertical bar and the vehicle head tube normally to be relatively rotated, and be unlikely and move to axial.

3) see through to use the extension vertical tube of different length or be about to extend the mode that vertical tube is cut into Len req certainly, can cooperate the height and position of adjusting handle, make it satisfy different riders' user demand.

Below in conjunction with accompanying drawing the utility model is described in further detail.
