Description

An angle-adjustable auxiliary bicycle handle

technical field

The utility model belongs to the field of bicycle manufacture and relates to a novel bicycle auxiliary handle device, in particular to a novel bicycle auxiliary handle with adjustable angle. the

Background technique

At present, bicycles are not only an environmentally friendly means of transportation for transportation and travel; more and more people use bicycles as fitness equipment for cycling and exercising; bicycles themselves are also a competitive sport. Because of the wide range of uses, the design of bicycles is more and more humanized, and the quality of the bicycle handle structure will directly affect the comfort level of users during bicycle use. The known bicycle auxiliary handle is to directly fix the auxiliary handle on the end of the main handle of the bicycle with screws, and the user can directly hold it on the auxiliary handle. However, when the general auxiliary handle is installed, the inclination angles of the left and right sides cannot be completely guaranteed to be completely consistent. Moreover, if the inclination angle of the auxiliary handle of the bicycle needs to be adjusted, it can only be reinstalled and adjusted, so as to adjust the inclination angle of the auxiliary handle of the bicycle at any time. Difficult and needs to be improved. The bicycle auxiliary handle of the utility model can help the user to quickly locate by first determining the relative position angle of the armrest and the sleeve boss during installation, and adjust the inclination angle of the handle after positioning to ensure that the inclination angle is consistent. At the same time, the bicycle auxiliary handle is installed. In the future, the inclination angle of the auxiliary handle can be adjusted anytime and anywhere, so that the user can adjust the inclination angle of the auxiliary handle according to his own needs under different road conditions, thereby improving the comfort of the bicycle. the

Detailed ways

As shown in Figure 1, the auxiliary handle of the utility model is composed of an inner sleeve 1, an outer sleeve 2, a positioning screw 4, a hand sleeve 5, and a shrapnel 6. To the through hole, the two ends of the inner sleeve 1 are provided with protrusions, and the cylinder body of the inner sleeve 1 is provided with a shrapnel installation groove 7, and the shrapnel 6 is fixed in the shrapnel installation groove 7; the outer sleeve 2 is a hollow cylinder, Both ends of the outer sleeve 2 are provided with protrusions toward the axial direction, and the shape of the end surface of the protrusion matches the outer wall surface of the inner sleeve 1. The inner wall surface of the outer sleeve 2 is provided with a groove 8 parallel to the axial direction. The cross-section of the groove 8 is a right-angled trapezoid, and the elastic piece 6 cooperates with the groove 8, so that the inner sleeve 1 can rotate in one direction relative to the outer sleeve 2; The positioning holes 9 are provided with a plurality of positioning holes 10 of the outer sleeve along the circumferential direction at corresponding positions on the outer sleeve 2, and the positioning screws 4 penetrate into the positioning holes 9 of the inner sleeve and the positioning holes 10 of the outer sleeve; The sleeve 5 is fixed on the outer sleeve 2 . Assemble the handle sleeve 5 with the inner sleeve 1, and finally fix it on the main handle of the bicycle through the clamping bolt 3. the

The handle sleeve 5 and the outer sleeve 2 of the device can rotate unidirectionally around the handlebar, and the bending angle of the shrapnel 6 is the same as the angle of the inclined surface of the groove 8 of the outer sleeve 2, so that the shrapnel 6 can be better adhered to. Coupling groove 8. When the sleeve 5 is rotated backward around the handlebar, the shrapnel 6 can move along the inclined boundary surface of the trapezoidal cross-section groove 8, and when the sleeve is turned in the opposite direction, the shrapnel 6 will be stuck in the right-angled trapezoidal groove. At the bottom of the groove 8, the end face of the shrapnel 6 is perpendicular to the groove and fully fits the reverse rotation of the locking device, so that the secondary handle of the bicycle can be adjusted at any time. In addition, a positioning screw 4 is arranged axially on the outer edge of the handle to fix the relative position between the handle sleeve 5 and the inner sleeve 1. After the adjustment of the angle of the handle sleeve is completed, the positioning screw 4 is screwed in, and the positioning screw 4 Penetrate through the inner sleeve 1 and penetrate into the round hole on the outer sleeve 2 with the same diameter as the screw (the number of positions of the round holes is the same as that of the groove 8), so as to lock the handle sleeve 5 and the inner sleeve 1 The relative position prevents the one-way rotation of the holding sleeve. the

It can be seen from the above that the new angle-adjustable bicycle auxiliary handle described in the utility model is indeed the first in the industry and meets the novelty requirements of the utility model patent, and its comprehensive innovative design meets the utility model patent requirements. Creative elements, with strong industrial mass production practicability. the

In addition, the exemplary solutions described here are only to explain the principles of the present invention. The above description should not be used to limit the scope of the present invention in any way. Those skilled in the art can utilize the principle of the utility model to design various implementations without going beyond the scope of the utility model. the
