Detailed Description

As shown in fig. 1 to 6, the present utility model provides a bicycle rear view mirror with changeable length, wherein the rear view mirror 1 comprises a mirror frame 10 and a rear view mirror body 20 mounted on the mirror frame 10; the main improvement is that:

the frame 10 has a first end 11 and a second end 12; the second end 11 is provided with at least two mounting holes 13 along the extending direction X of the frame 10, as shown in fig. 2, and a screw hole 14 is respectively disposed in a radial direction of the mounting holes 13 and is communicated with the mounting holes.

The extending direction X is a general direction extending from the first end 11 to the second end 12, and may be a long axis direction of the frame 10.

The first end 11 may be directly or indirectly mounted and fixed to a handlebar of a bicycle, for example, by a connecting fastener, however, the fixing structure of the first end 11 is not the technical point of the present utility model and will not be described herein.

A bushing 30 is rotatably nested in a selected one of the mounting holes 13 of the frame 10 and defines a socket 31 therein.

The mirror body 20 has a ball head 21 for being positioned in the socket 31 of the bush 30. It can be seen that the ball head 21 of the mirror body 20 and the ball socket 31 of the bush 30 together form a common ball joint, so that the mirror body 20 can rotate in three degrees of freedom. In addition, the rearview mirror body 20 of the present embodiment includes a mirror frame 20a, and a lens 20b mounted on the front surface of the mirror frame 20a, and the ball 21 is formed or disposed on the back surface of the mirror frame 20 a.

A fastener 40 is selectively threaded into a selected one of the threaded bores 14 of the frame 10 to bear against the peripheral wall of the bushing 30 in the opposite mounting bore 13, allowing the bushing 30 to resiliently tighten the internally nested ball head 21. The fastener 40 of this embodiment is a bolt, such as a headless bolt.

In this embodiment, as shown in fig. 3 and 5, the inner hole wall of the mounting hole 13 is provided with at least one limiting hole wall 131 extending along the axial direction to form a tangential plane; the peripheral wall of the bushing 30 is provided with at least one limiting stop wall 32 extending along the axial direction to form a tangential plane, and the limiting stop wall 31 can be positioned in a matched manner, so that the bushing 30 can be limited to rotate.

Preferably, two limiting hole walls 131 are disposed opposite to the inner hole wall of the mounting hole 13, and the positions of the limiting hole walls 131 at the position of the mounting hole 13 and the positions of the screw holes 14 communicated with the mounting hole 13 are perpendicular to each other. Similarly, two limiting blocking walls 32 are symmetrically arranged on the outer peripheral wall of the bushing 30, and can be respectively and coincidently positioned on each limiting hole wall 31.

In this embodiment, the ball socket 31 of the bushing 30 has an opening 311 and a bottom wall 312, and the limiting wall 32 is respectively provided with a groove 313 to the bottom wall 312 along the axial direction from the end edge around the opening 311, so that the peripheral wall of the bushing 30 can generate elastic tightening effect when being abutted by the fastener 40.

Furthermore, since the positioning hole wall 131 is perpendicular to the screw hole 14 communicating with the mounting hole 13 at the positioning position of the mounting hole 13, as shown in fig. 5, after the fastener 40 is screwed into the screw hole 14, the bushing 30 can generate a good elastic tightening effect by means of the groove 313 on the positioning hole wall 131, so as to tightly clamp and fix the ball head 21 nested therein, thereby enabling the rearview mirror body 20 to be adjusted to rotate and be firmly positioned at any suitable angle.

In this embodiment, a positioning groove 33 is provided on the peripheral wall of the bushing 30 opposite to the screw hole 14, so that the fastener 40 can be abutted and positioned.

In this embodiment, as shown in fig. 4, 6 and 7, the mounting holes 13 of the frame 10 each have an inlet end 132; the bushing 30 has an opposite inner end 34 and an outer end 35, the inner end 34 being insertable from the inlet end 132 of the mounting hole 13, the outer end 35 being formed with a retaining lip 351 for retaining the opposite walls of the mounting hole 13 around the inlet end 132. With this design, the bushing 30 will facilitate accurate and quick installation and positioning in the mounting hole 13 to ensure that the locating groove 33 thereon can be aligned with the screw hole 14 on the frame 10 and that the fastener 40 for subsequent screwing can be accurately positioned against.

As can be seen from the above description, when the rearview mirror 1 of the present utility model is mounted on a bicycle handlebar, a rider can choose or adjust the mounting position of the rearview mirror body 20 on the mirror frame 10 according to the individual stature, preference or actual requirement, for example, when the user wants the rearview mirror body 20 to be closer to the inner side of the body, the ball 21 of the rearview mirror body can be chosen or changed to the mounting hole 13 of the mirror frame 10 further from the second end 12; conversely, if the user wishes to have the mirror body 20 be farther from the body, the sphere 21 can be selected or shifted to the mounting hole 13 of the frame 10 nearer the second end 12. Accordingly, the length of the rearview mirror 1 can be freely adjusted and changed by the rider, and the distance position of the lens 20b on the rearview mirror body 20 can be freely adjusted and changed by the rider, so as to meet the personal best demands of the rider.
