Description

Anti-toppling bicycle

Technical Field

The utility model relates to a bicycle field especially relates to prevent empting bicycle.

Background

The strutting arrangement of bicycle generally is located the position of bicycle rear axle, and the basket generally is leading front end to the handlebar, and the steadiness that rearmounted strutting arrangement was difficult to guarantee the bicycle and parks has been decided to the hub connection mode of front fork and head tube, especially under the condition that the basket was filled with the heavy object, very easily blown or external force influence leads to the handlebar distortion, and the front wheel diversion causes the bicycle to be blown down or turn on one's side.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure is provided, it is firm to park, is difficult for letting wind blow or other external force influence and prevent empting bicycle.

The utility model discloses a realize through following technical scheme:

an anti-toppling bicycle comprises a front fork tube, a front tube, a lower tube and an upper tube, wherein the front tube is sleeved on the front fork tube, one end of the lower pipe is welded on the outer side wall of the front pipe, an upper pipe is arranged right above the lower pipe, one end of the upper tube is also welded on the outer side wall of the front tube, the outer side wall of the front fork tube is provided with a fixing ring in a surrounding way, the fixing ring is of an annular structure with a clamping groove arranged at the outer edge, the clamping groove is of a semicircular groove structure which is inwards concave in the radial direction, the outer side wall of the front tube below the fixing ring is also provided with a positioning base which is a cylindrical structure with a vertical through groove at the tail end, the positioning base is characterized in that a positioning bolt is arranged at the tail end of the positioning base, a clamping rod is arranged on the positioning bolt, the clamping rod is a cylinder which can be lapped on the clamping groove, and the positioning bolt is in threaded connection with the clamping rod and the positioning base.

Furthermore, a backing plate is fixed on the positioning base and is located under the clamping rod.

Further, the backing plate is made of rubber.

Beneficial effects of the utility model

The utility model provides a bicycle quiescent condition is many because of receiving transverse section exogenic action to lead to the front fork pipe diversion then the front wheel removes and makes the automobile body unbalance finally topple over, the utility model provides a prevent empting the bicycle can pass through the relative position of stuck bar overlap joint indirect fixed front fork pipe and head tube on the draw-in groove, thereby make the front wheel can not redirecting, the automobile body still can keep the fixed of front wheel direction under the wind-blowing that receives transverse section direction or other exogenic actions like this, avoid producing the front wheel direction and twist reverse along with the displacement of external force direction, thereby guarantee the steadiness of parkking, in addition, positioning bolt all is threaded connection with stuck bar and positioning base, the stuck bar can not lead to the relative position of front fork pipe and head tube to be difficult to the condition fixed along stuck bar lateral sliding displacement like this.

Furthermore, a backing plate is fixed on the positioning base and is positioned under the clamping rod, so that the clamping rod cannot collide with a vehicle body below the clamping rod due to bumping of a vehicle in running.

Furthermore, the backing plate is made of rubber, the clamping rod and the backing plate are elastically collided due to bumping of a vehicle in running, and the joint of the clamping rod and the positioning bolt cannot be abraded and loosened under the action of buffering force.

Detailed Description

As shown in figure 1, the utility model provides an anti-toppling bicycle, including a front fork 1, a front tube 2, a lower tube 3 and an upper tube 4, the front tube 2 is sleeved on the front fork 1, one end of the lower tube 3 is welded on the lateral wall of the front tube 2, the upper tube 4 is arranged right above the lower tube 3, one end of the upper tube 4 is also welded on the lateral wall of the front tube 2, a fixing ring 5 is arranged on the lateral wall of the front fork 1 in a surrounding manner, the fixing ring 5 is an annular structure with a clamping groove 6 at the outer edge, the clamping groove 6 is a semicircular groove structure which is radially inwards concave, a positioning base 9 is also arranged on the lateral wall of the front tube 2 below the fixing ring 5, the positioning base 9 is a cylindrical structure with a vertical through groove at the tail end, a positioning bolt 8 is arranged at the tail end of the positioning base 9, a clamping bar 7 is arranged on the positioning bolt 8, but the card stick 7 overlap joint is in cylinder on the draw-in groove 6, positioning bolt 8 with card stick 7 with positioning base 9 threaded connection is in the same place, card stick 7 with positioning bolt 8's hookup location is located between the vertical groove that runs through that positioning base 9's end was seted up, be fixed with backing plate 10 on the positioning base 9, backing plate 10 is located under the card stick 7, backing plate 10 is the rubber material.

The working mode is as follows: the bicycle is not prevented from being bumped during riding, the clamping rod 7 can continuously touch the backing plate 10, and the backing plate 10 is made of rubber, so that the impact energy of the clamping rod 7 can be offset by the elastic action, and the clamping rod 7 or other contacted parts cannot be damaged due to bumping of the running bicycle.

After the bicycle is parked, the front wheel is adjusted to be collinear with the rear wheel, then the clamping bar 7 is in lap joint with the clamping groove 6, so that the relative angle between the front fork tube 1 and the front tube 2 is fixed, the front wheel is prevented from being turned to and moved under the action of external force, the gravity center of the bicycle body is changed to cause the toppling of the bicycle, and when the bicycle is ridden next time, the clamping bar 7 is pulled out from the clamping groove 6, and the bicycle can be ridden normally.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
