Angle adjustment structure of vertical tube seat of bicycle horizontal handle

The present invention relates to a bicycle connecting pipe structure, in particular to a vertical pipe seat angle adjusting structure of a bicycle horizontal handle capable of quickly adjusting a handle angle.

According to the conventional bicycle, the rear wheel is connected by a frame, and the front wheel is connected to the front end of the frame by a vertical pipe, so that the wheel can perform the steering function of the bicycle through the rotation of the vertical pipe, and the top end of the vertical pipe is fixed. There is a connecting tube, and a horizontal handle is fixed at the other end of the connecting tube, and the handle of the rider is provided by the horizontal handle. However, in view of the difference in the height of the rider and the ratio of the hands and feet, the handle suitable for each person The angles of the elevation angles are different, so the bicycle handles have the function of adjusting the angle of the handles, so that the user can adjust when riding the bicycle, and the adjustable horizontal handle structure of the bicycle is formed by the two pipe members being pivoted. The pipe member is formed with a pivoting portion, and the pivoting portion is locked and fixed by a bolt, and the opposite faces of the two pivoting portions are designed with a rough surface, which can be formed when the bolt and the nut are locked. The rough surface is clamped and fixed, and the relative angle adjustment of the two pipe fittings can be performed when the bolt is loosened. However, it is not difficult to find out that the above-mentioned conventional structure has some shortcomings, mainly the main reason. It is as follows: After the bolt of the connecting pipe is loosened, the horizontal handle is loose and cannot be fixed, so it is necessary to grasp the horizontal handle with one hand, so that the other hand cannot simultaneously control the relative locking of the bolt and the nut, so most of them Everyone will first tighten the bolt and nut tightly, then let the pivotal parts of the two pipe parts adjust the angle in the state of not easy to rotate, and after determining the angle of the horizontal handle, then the bolts are locked with both hands. The nut is too cumbersome and difficult to operate. If the adjustment angle is not suitable after the trial ride, it is necessary to repeat a complicated adjustment action. Therefore, there is a lack of elevation angle that is not easy to quickly adjust the horizontal handle. Moreover, when the bicycle is used for a long period of time or when driving a bumpy road surface, the loosening of the bolt is prone to occur, and the two pipe members of the connecting pipe are only clamped and fixed by the rough surface of the pivoting portion, so that the elevation angle of the horizontal handle may be loosened. Can't effectively fix the angle he wants to use, causing riding It is inconvenient to take advantage of it, and it is more serious to use it.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a vertical tube seat angle adjustment structure for a bicycle horizontal handle in view of the above-mentioned shortcomings existing in the prior art.

a sleeve is formed at one end with two parallel symmetrical extension arms, and an outer edge of the extension arm is formed in a circular arc shape with a tooth surface, and the extension arm has a screw hole at a same center of the tooth surface, and the two extensions a conical portion is protruded from the periphery of the opposite inner screw hole, and a bolt is locked at the screw hole, and the sleeve is formed with a tightening portion at the other end, and the binding portion forms a connection to the bicycle standpipe Fixing, a glove has a connecting portion protruding at one end, and a locking portion is formed at the other end, the connecting portion is formed with an elliptical hole, and the opening at both ends of the elliptical hole is retracted to form a conical groove, and the handle is formed The glove is formed with a circular arc tooth surface facing the connecting portion at two sides of the adjacent connecting portion, and the glove is disposed between the two extending arms of the sleeve with the connecting portion, and the elastic limit is formed by the tapered groove and the conical portion. And providing the bolt through the elliptical hole so that the arc tooth surface of the glove can be engaged with the tooth surface of the sleeve, and the lock portion of the glove is locked with a curved cover and is curved The cover and the locking portion form a pair of bicycle handles Fixing knot.

Wherein, the elliptical hole of the glove communicates with the through hole through a through hole, and the glove is provided with a spring at the through hole, and one end of the spring is fixed to the locking portion, and the other end of the spring is coupled to the bolt position, so that the glove is The arc tooth surface can be toothed on the tooth surface of the sleeve, and the glove is formed with two card slots at one end of the locking portion away from the joint portion, and the card slot is provided with a rod body to fix the spring to the lock The way of the joint position is set on the rod body.

The first main purpose of the present invention is that the tightening portion of the sleeve is coupled to the bicycle standpipe, and the lock portion of the glove and the curved cover are formed to be locked and fixed to the bicycle handle. When the elevation angle of the handle is to be adjusted First, loosen the bolt of the screw at the screw hole, so that the glove can be pulled outward through the elliptical hole space, and the micro-outer of the extension arm is formed by pressing the conical groove of the glove to make the circle The curved tooth surface can be separated from the tooth surface of the sleeve, thereby adjusting the elevation angle of the glove, thereby facilitating the adjustment of the handle angle easily and quickly, thereby improving the convenience of the angle adjustment, and Through the multi-tooth toothing of the tooth surface and the arc tooth surface, a plurality of steps for adjusting the handle angle are formed, so as to improve the practicability.

The second main purpose of the present invention is that the glove is provided with a spring at the through hole, and one end of the spring is fixed to the locking portion, and the other end of the spring is coupled to the bolt position, and the spring is biased toward the sleeve. The direction is abutted, and the extension arm of the sleeve is used to clamp the screw lock of the joint of the glove, thereby further strengthening the meshing effect between the tooth surface and the arc tooth surface, so as to apply force to the bicycle handle or the bicycle to travel on the bump When the road surface is maintained, the relative angle between the sleeve and the glove can be maintained, thereby improving the stability of use.
