Description
Technical field
The utility model relates to a kind of two and takes turns battery-driven car, bicycle accessories, and more particularly, it relates to a kind of rear wheels of electric vehicle bracing frame.
Background technology
Two take turns the common walking-replacing tool that battery-driven car is broad masses, and environmentally safe is so should widely popularize, but it is heavier to compare bicycle electric vehicle body, if once trailing wheel makes trailing wheel puncture gas leakage to continue to push away and secondary can be caused to lock to cover tire and steel ring badly whole rear tire seriously may to be made to scrap the place originally only need mending lower leakage, cause larger economic loss owing to encountering spine.
For the problems referred to above, be that a kind of electric vehicle Rear wheel support frame mentioned in the Chinese patent of 2014200090319 solves and to utilize when rear tire is blown out or do not had gas the roller be arranged on Rear wheel support frame to replace trailing wheel to reduce secondary damage for rear tire temporarily at application number, again such as application number be 201220120709.1 the one novel two brought up to of Chinese patent take turns battery-driven car, supporter of motorcycle replaces the damage of rear wheel minimizing to rear tire secondary when being also and utilizing the roller be located on bracing frame to arrive, there is the problem of inconvenient operation when needing to use roller in the above-mentioned two sections of patents mentioned simultaneously, battery-driven car own or motor bike are comparatively heavy, secondly what first will do is mention battery-driven car to navigate to assigned address roller is moved on to or installed, time-consumingly to require great effort again, one man operation is inconvenient, instrument in addition is also wanted to realize dismounting, practicality is poor, and be exposed outside roller and easily lose or wearing and tearing.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rear wheels of electric vehicle bracing frame, easy to operate time saving and energy saving, and structure is simple, supporting & stablizing, roller long service life.
For achieving the above object, the utility model provides following technical scheme:
A kind of rear wheels of electric vehicle bracing frame, comprise two bracing frames be arranged in parallel, support frame as described above comprises vertical rod, tilting bar and horizon bar, described vertical rod top is provided with the fixed orifice be arranged on battery-driven car wheel shaft, and the end of described horizon bar is connected by pipe link, and the bottom of described vertical rod is provided with opening, described vertical rod is provided with slippage chamber, described slippage chamber is communicated in opening, is provided with expansion chucking mechanism in described slippage chamber, and described expansion chucking mechanism rotary connection has roller.
By above-mentioned technical requirements; roller is arranged on expansion chucking mechanism; expansion chucking mechanism is placed in again in slippage chamber; only need stretch out roller by expansion chucking mechanism when needing to use roller and clamp location and fix; easy to operate, used time roller is not placed in slippage chamber, and well protection roller prevents from coming off when gouging abrasion or collision; add the service life of big roller, and the bracing frame stability utilizing leg-of-mutton stability to make is higher.
As preferably, described expansion chucking mechanism comprises slide block, the first elastic element and jumping bean spring, described slide block is arranged in slippage chamber by the first elastic element, the described vertical rod forward surface paralleled is equipped with chute, described slide block connects depression bar, described depression bar is through chute and slippage is connected to chute, described chute is communicated with slippage chamber, described slide block slippage is connected to slippage chamber, described vertical rod is provided with spacing hole, is connected to spacing hole when described roller stretches out described jumping bean Spring Card when slippage chamber is placed in the external world.
Pass through technique scheme, utilize depression bar to connect two pieces of slide blocks makes two pieces of slide blocks to move simultaneously, and be connected to spacing hole by jumping bean Spring Card and realize spacing fixing, firmly haul slide block by the elastic potential energy of the first elastic element and make it can not fall down when not needing work and can reset after using.
As preferably, described depression bar is provided with stretcher, and described stretcher is arranged in the middle of depression bar.
Pass through technique scheme, arrange stretcher get well that being in blows out needs to stretch out roller time slam stretcher firmly and lift battery-driven car gently roller just can be made to stretch out downwards by pin, power without the need to the power phase opponent with in one's hands and pin wants large, makes whole process very laborsaving.
Compared to existing technology, being preferentially of the rear wheels of electric vehicle bracing frame provided of the present utility model: easy to use time saving and energy saving, structure is simple, roller long service life.
