Folding type bicycle back mirror

Technical field

The utility model relates to a kind of vehicle mirrors, relates in particular to a kind ofly to improve bicycle driving safety, and is convenient to the folding type bicycle back mirror that folding is taken in.

Background technology

Bicycle is very convenient and one of vehicle easily, because it is to utilize strength that the people the tramples source as power, therefore can not produce energy resource consumption and air-polluting problem, add the most light weight of bicycle, control easily, therefore now become the instrument of urbanite as short distance traffic transportation and Sport ﹠ Casual.

But in busy now society, bustling with vehicles on the road, up and-down vehicle is not only numerous and speed is very fast, and slow bicycle running is on road, if do not note back car slightly, be easy to suffer that the rear sails the overtaking collision of the self-propelled vehicle that comes, and damage for the bicycle rider, its life of severe patient entail dangers to, because generally add back mirror with the attention back car on the self-propelled vehicle now, and easy transport facility such as bicycle more needs to be equiped with safety devices such as back mirror, so that the bicycle rider is when lane change or turning, can note back car, to guarantee traffic safety.

Yet if installing not only can not mutually combine on the structure as the back mirror as the self-propelled vehicle on bicycle, and the automobile-use back mirror can't amount to mostly, so can make bicycle occupy bigger space when taking in, and then bring inconvenience.

The utility model content

Because existing bicycle is noted back car for convenience of the rider, guarantee traffic safety, the utility model provides a kind of folding type bicycle back mirror, and it has the bicycle of raising driving safety and is convenient to the advantage that folding is taken in.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of folding type bicycle back mirror is characterized in that, comprising: the mirror body, and back side central authorities are provided with pivot block; Strut bar, for having the hollow lever of suitable sinuousness, and upper end and lower end are provided with can be along first turning joint and second turning joint of strut bar axle center rotation, first turning joint outside is pivoted and has the pivot block of mirror body, second turning joint outside is pivoted with a pivotal part, this pivotal part is provided with pivot away from a side of second turning joint, and the pivot outside is provided with scrobicular ring; Connecting device is made up of upper and lower block, and the side that upper and lower block is relative is formed with the arcuation recess, and upper and lower block is by fixation kit combination, and last block central authorities form the perforation that the pivot of confession pivotal part wears; C shape clasp, it is to be located on the scrobicular ring of pivot of pivotal part.

Aforesaid folding type bicycle back mirror, wherein first turning joint and second turning joint are provided with the pivot that the outside has scrobicular ring with respect to an end of strut bar, cooperating central authorities to be provided with the coupling collar that perforation, the outside be provided with screw thread combines with strut bar, this inboard, strut bar two ends is provided with the screw thread that screws togather with the coupling collar outside screw, and pivot be located on the scrobicular ring to be connected with coupling collar with C shape clasp.

The utility model makes back mirror can reach the free movable effect that pivots in five places by pivot block, first turning joint, second turning joint, pivotal part and connecting device, therefore but the handle of relative proper motion car carries out folding and takes in, so can not take up space and can guarantee traffic safety.
