Description

The utility model relates to a bicycle auxiliary handle which can be used for adjusting the angle. Fit a set of semicircular clamping blocks with concave arc grooves in the upper end of the hole, so as to accept the lower cylindrical sphere of the auxiliary handle, so that two lugs made of one piece are provided on the periphery of the upper end of the hole and a short bolt is positioned; while the side In the perforation of the larger diameter on the side, a hollow inclined-plane column tube and an opposite-shaped inclined-plane nut head must be assembled with a long bolt to fit in the tubes at both ends of the handlebar and fix it; in order to achieve the change of holding angle Quick and easy adjustment function.

Press, the auxiliary handle structure of the bicycle generally seen, that is, as shown in Figure 1: it is on the position A1 at both ends of the handlebar A, and its auxiliary handle B is in the shape of an elbow, and has a perforation B1 at the lower end to make it After being inserted, a bolt C is used to approach and lock it for fixation. However, since the shoulder width of each rider is not the same, each rider must first loosen the bolt C under the auxiliary handle B before operating the auxiliary handle B, and then make a displacement adjustment to fit the shoulder. Wide, and then re-lock the bolt C in place, which is convenient to control; but invisibly, the bolt C used for adjustment is loosened and locked too frequently, and finally the bolt C and the auxiliary handle B are locked with the bolt C The position is easy to crack and break; moreover, sometimes the adjusted displacement cannot be completed at one time, and more than several times of trial and error are required, which is the biggest shortcoming of this structure.

The purpose of this utility model is to provide a bicycle auxiliary handle that can quickly change the holding angle and adjust the angle easily in view of the many defects in the holding of the above bicycle handle.

According to the utility model, a bicycle auxiliary handle that can be used to adjust the angle is formed by connecting the upper end and the side of the main body to form a through hole with different diameters, and the content of the upper end of the hole is packed into a set to form a concave arc groove. The semicircular clamping block of the groove is in a rotating state to accept the lower cylindrical sphere of the auxiliary handle, and then a short bolt is placed through the upper perforation with two lugs on the periphery; and a hollow inclined surface must be assembled in the perforation on the side The column tube and the inclined nut head in opposite shape are combined with a long bolt to fit in the tubes at both ends of the handlebar and fixed; so that it can be adjusted according to the changing holding angle according to the personal situation, so as to achieve the effect of quick and easy adjustment and transformation .

Another aspect of the present utility model is to provide a bicycle auxiliary handle structure that can be used for adjusting the angle; wherein, the two integrally formed lugs formed at the proper position on the perforated periphery of the upper end of the connecting body have a The groove gap is cut, and the holes in the middle of the two lugs are smooth and threaded, so that the auxiliary handle connected to the main body can be effectively connected to a set of concave arc groove semicircle clamps for any angle adjustment. , and then locked and positioned by a short bolt through the smooth and threaded holes of the two lugs.

Another aspect of the present utility model is to provide a bicycle auxiliary handle structure that can be used to adjust the angle; wherein, a hollow column tube with an inclined plane and an inclined nut head with a corresponding shape are assembled in the tubes at both ends of the handlebar. Use a long bolt to gradually screw the column tube and the nut head close, so that the two slopes can slide to make the two column tubes and the nut head sticky and fixed without falling and loosening.

For the rest, the structural features and operation of the present utility model are described in detail in the form of illustrations. in:

Fig. 1 is a perspective view of a known structure and assembly.

Fig. 2 is a three-dimensional illustration of the structure of the utility model.

Fig. 3 is a sectional view of the combined utility model.

Fig. 4 is the embodiment figure of the utility model structure.

Fig. 4A is a motion diagram of the utility model auxiliary handle ball.

First of all, please refer to Fig. 2 and show as shown: a kind of bicycle auxiliary handle structure that can be used as adjustment angle of the utility model; The perforated holes 11 and 12 are in one phase but with different diameters, and a set of semicircular clamping blocks 21 and 22 with concave arc grooves 2A are installed in the upper end of the perforated hole 11 to receive the auxiliary handle 3. The lower cylindrical ball 31 is in a rotating state (such as Fig. 4A), after that, there are two lugs 111, 112 which are integrally made on the periphery of the perforation 11 at the upper end, and there is a groove gap 115 in the middle, and the centers of the faces of the two lugs 111, 112 are respectively smooth holes 113 and threaded hole 114, two lugs 111, 112 are locked and clamped and positioned by a short bolt 6B; and in the larger-diameter perforation 12 on the side, a hollow inclined-plane column tube 4 must be assembled and be in a relative shape. The beveled nut head 5 is connected by a long bolt 6A passing through the connecting body 1, the beveled column tube 4 to the central threaded hole 51 of the beveled nut head 5.

In this way, after the inclined column tube 4 and the inclined nut head 5 are installed in the two ends A1 of the handlebar, the long bolt 6A must be screwed and actuated to make the column tube 4 and the nut head 5 Gradually approach each other, so that the two inclined surfaces 41, 51 can slip and make the two column pipes 4, the nut heads 5 form a stagnation and stick to the A1 in the pipe fixed on the handlebar, which is in a fixed position, as shown in Figure 3; after that, due to The lower end of the auxiliary handle 3 is a cylindrical sphere 31, which is accommodated in the semicircular clamping blocks 21 and 22 in a group of concave arc grooves 2A connected to the upper end of the main body 1 through the hole 11, so that it can be transferred at any angle of 360° naturally. The direction is as shown in Figure 3 and Figure 4. After the rider moves to the most appropriate position, the smooth hole 113 and the threaded hole 114 of the two lugs 111 and 112 on the periphery of the upper end of the main body 1 are passed through. A short bolt 6B twist-lock pliers are tightly positioned, so that the angle can be changed appropriately according to individual conditions, and the fast and easy effect of adjustment and transformation can be achieved.

To sum up, compared with the known structure, the utility model does have the practical effect of more convenient grip adjustment.
