Description

The bicycle handle setting device

The utility model relates to a kind of bicycle handle, particularly a kind of bicycle handle setting device of adjusting the bicycle handle angle.

The kind of existing bicycle is extremely many, as RV recreational vehicle, contest is with sport car and cross-country car etc., and because the purpose difference of various vehicle utilization, the environment that it adapted to is also different, therefore also different to the requirement of body construction, wherein RV recreational vehicle is emphasized easy, and sport car is emphasized lightly, cross-country car is then owing to be to apply to the field mainly, therefore its body construction is emphasized firm, and that its handle is not only emphasized is firm, also must have simultaneously the function of adjusting angle, to adapt to all-environment needs, be the grip structure of existing cross-country car as shown in Figure 6, the preceding forked standard 50 of this grip structure mainly is to extend upwardly and be provided with the sheathed standpipe 52 of frame vertical tube of can buying car in installments in takeing on 51 central authorities once, under take on 51 both sides and set firmly a front fork stem 53 respectively, and on each front fork stem 53, correct and be installed with a C pencil of forms ring 55 respectively, these beam ring 55 two ends have outwards protruded out cooresponding projection 56 respectively, 57, make beam ring 55 can utilize bolt 58 to be locked on the front fork stem 53, two beam rings, 55 relative inner of two front fork stems 53 are respectively equipped with a leading sheet 60 again, these two leading sheets, 60 tops are formed with C clamp 61, and C clamp 61 medial margins are formed with a dissected valley 62, and utilize bolt 63 screw locks to establish handle 70 in C clamp 61 with lock, and beam ring 55 screws 570 places, correspondence top, leading sheet 60 stage casing are formed with a perforation 64, beam ring 55 screws 570 places, leading again sheet 60 hypomere correspondences below also are formed with one group of perforation 66 with camber line, utilize screw rod 65 respectively, 67 are locked on leading sheet 60, following two beam rings, 55 sides make the user can utilize the series of perforations 66 of leading sheet 60 hypomeres to change the purpose of itself and front fork stem 53 angles.

Though above-mentioned handle can utilize the perforation of leading medium film section to adjust angle, yet because its each perforation is respectively to be independent setting, therefore when user's desire is adjusted the angle of handle, then need the complete spiral of the screw rod on the leading sheet is gone out, select suitable perforation screw lock then in addition, so step very bothers, cause the user in the inconvenience of adjusting on the handle angle, moreover because leading sheet bottom area is limited, therefore its perforation that only can form a little is adjusted usefulness for the user, and can't satisfy user's demand fully, and causes inconvenience and puzzlement in the use, historical facts or anecdotes is improved at this shortcoming of grip structure being necessary, so that the user to be provided better convenience.

The purpose of this utility model is to provide a kind of bicycle handle setting device, and its assembling is simple, can easily adjust the angle of bicycle handle, and have bigger setting range.

The technical solution of the utility model is to provide a kind of bicycle handle setting device, be that the following shoulder central authorities of forked standard before extend upwardly and are provided with the sheathed standpipe of frame vertical tube of buying car in installments, and following shoulder both sides also set firmly a front fork stem respectively, each front fork stem upper end utilizes the beam ring lock to be provided with a leading sheet respectively again, each beam ring two ends is formed with a projection respectively, wherein a projection is formed with a counterbore, and another projection is formed with a cooresponding screw, it is characterized in that;

Two leading sheet tops form ringent semi-circular arc groove, wherein the arc rooved face is formed with sawtooth, and leading sheet top is provided with the cover plate of a corresponding arc groove, this cover plate inner edge also is formed with the sawtooth of corresponding arc grooving saw tooth, establish a micro-adjusting mechanism to utilize the cover plate lock, moreover the screw place of two leading medium film sections beam ring above the front fork stem of corresponding both sides is formed with a perforation respectively, establish in order to utilize screw rod lock, the screw place of two leading sheet hypomere correspondences below beam rings is formed with the poroid adjustment of a long cucurbit respectively and connects the hole again, this adjustment Lian Kongshi is made up of one group of adjacent location division with camber line, and be formed with neck between each adjacent positioned portion respectively than path, make screw rod can cooperate a positioning tube that leading mortice lock is established on the beam ring

And aforesaid micro-adjusting mechanism be in axostylus axostyle two ends respectively clipping two relative intermediate plates are arranged, wherein the front and rear sections of each intermediate plate opposite edges is formed with the pull clip slot of axostylus axostyle and handle of a folder respectively, and each clip slot surface is formed with sawtooth respectively, the two ends of two corresponding intermediate plates are sealed with bolt again, and the axostylus axostyle two ends are formed with toothed segment respectively.

Aforesaid bicycle handle setting device is characterized in that: the intermediate plate of micro-adjusting mechanism can be positioned at the relative inner of two leading sheets.

Aforesaid bicycle handle setting device is characterized in that: the intermediate plate of micro-adjusting mechanism can be positioned at the relative outside of two leading sheets.

The utlity model has following advantage, such as;

1 is easy to adjust the angle of bicycle handle: because leading sheet is to utilize positioning tube to be sheathed in the location division in the company of adjustment hole, the screw rod that passes positioning tube then can pass for the neck that leading sheet adjustment connects the hole, therefore the user is when adjusting leading sheet angle, only need screw rod is slightly withdrawed from, the location division that makes positioning tube can break away from leading sheet can be adjusted, and it is much easier screw rod need to be produced this adjustment entirely compared to existing person.

2 are convenient to assembling: because the top of leading sheet is to form opening shape arc groove, and utilize the cover plate lock to establish, therefore the user is when handle assembled, the brake spanner at handle two ends and anti-sliding sleeve need not pulled down, handle directly can be locked on the leading sheet, be to be closed compared to existing leading sheet owing to C clamp, so handle is when assembling, other parts can not be assembled in the handle end, so that the utility model can be convenient to the user is handle assembled.

3 setting ranges are bigger: because leading sheet top is provided with micro-adjusting mechanism in addition, and the axostylus axostyle two ends of micro-adjusting mechanism are arranged with toothed segment, and make micro-adjusting mechanism adjust angle by leading relatively sheet, and can pull on leading sheet by firm folder, reach the purpose that increases setting range.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
