Abstract
The utility model discloses a forward turnover-proof mountain bike during downhill process. The mountain bike comprises a bicycle frame, as well as a front wheel and a rear wheel which are connected with the bicycle frame, a seat arranged on the bicycle frame, and a transmission device; the bicycle frame is connected with a front fork and a handle stand; the handle stand is connected with the handle and a ratchet wheel; a ratchet shaft is connected with the front fork or the bicycle frame; a ratchet pawl is hinged on the front fork or the bicycle frame; the pawl head of the ratchet pawl can be connected with the ratchet wheel; a hand-operated switch is connected on the ratchet pawl; and a return spring is arranged between the front fork and the ratchet pawl or between the bicycle frame and the ratchet pawl. The mountain bike adopts an adjustable handlebar, and the bicycle handlebar can be moved backward by rotation when the bike goes down a steep slope, so that the entire center is moved backward, and the turnover caused by fronted center when the mountain bike goes down a steep slope is avoided. The adjustable structure is simple and convenient to use.
Description
Technical field
The utility model belongs to non-power-driven vehicle, is specifically related to a kind of mountain bike of turning over before the descending of preventing.
Background technology
It comprises vehicle frame present mountain bike, vehicle frame bonded assembly front-wheel and trailing wheel, the chair of choosing a place to give a banquet on the vehicle frame, driving device, vehicle frame connects front fork and integral cast handle frame, and the handgrip frame connects handgrip, and the angle of this handle is nonadjustable, in the traveling on mountainous region process particularly in the process on following abrupt slope since the reach of center of gravity turn over before causing easily.
Summary of the invention
The purpose of this utility model is to provide that a kind of handlebar angle can regulate prevents the mountain bike that turns over before the descending, to address the above problem.
The technical solution of the utility model is: prevent the mountain bike that turns over before the descending, it comprises vehicle frame, vehicle frame bonded assembly front-wheel and trailing wheel, the chair of choosing a place to give a banquet on the vehicle frame, driving device, vehicle frame connects front fork and handgrip frame, and the handgrip frame connects handgrip, the handgrip frame connects ratchet, ratchet shaft is connected with front fork or vehicle frame, the ratchet that is articulated and connected on front fork or the vehicle frame, and the pawl head of ratchet can be connected with ratchet, connect hand switch on the ratchet, be connected retracing spring between front fork or vehicle frame and the ratchet.
The utility model adopts adjustable handlebar.When following abrupt slope, will move after the handlebar rotation, thereby make and move behind the whole center, the reach of when avoiding down the abrupt slope because center causes overturning.This adjustment structure is simple and convenient.
Description of drawings
Fig. 1 prevents the mountain bike scheme drawing that turns over before the descending.
Fig. 2 ratchet connection structure scheme drawing.
The specific embodiment
As shown in Figure 1, the structure of bicycle and existing mountain bike structural similitude comprise vehicle frame 10, vehicle frame 10 bonded assembly front-wheels 11 and trailing wheel 12, the chair 13 of choosing a place to give a banquet on the vehicle frame 10, driving device 14, vehicle frame 10 connects front fork 15 and handgrip frame 16, and handgrip frame 16 connects handgrip 2, concrete not tired in detail stating.
Connect supporting plate frame 18 on the vehicle frame 10, ratchet 4 is in supporting plate frame 18.The pawl head of ratchet 5 can be connected with ratchet 4; Ratchet 5 is connected with pole on the vehicle frame 10 by hinge 7.Be connected retracing spring 6 between vehicle frame 10 and the ratchet 5.Handgrip frame 16 is connected (shown in Figure 2) with ratchet 4 by screw thread 9.Bonded assembly rotary knob 1 on the handgrip 2, bonded assembly control line 3 between rotary knob 1 and the ratchet 5.
As shown in Figure 2, ratchet shaft 8 passes supporting plate frame 18 and is connected with ratchet 4.
Instantly during the abrupt slope, by pressing rotary knob 1, rotary knob 1 is by pulling control line 3 pulling ratchets 5.Ratchet 5 unclamps with ratchet 4, and handlebar just can rotate around ratchet shaft 8 (screw) like this, reaches the purpose of adjustment.Ratchet shaft 8 plays the effect that connects handlebar and car bottom section.Couple together by screw thread 9 between handlebar 2 and the ratchet.Under the normal circumstances, the retracing spring 6 of ratchet can not unclamp between the pawl-and-gearing by there being certain pretension effect to make.When unclamping the rotating handles master cock, retracing spring 6 makes that ratchet returns the home position again and ratchet is stuck.
Claims (3)
