Abstract
The invention relates to a rear wheel double-support safety device for an electric bicycle. The device comprises double supports, a rear wheel shaft, a rear wheel fastening nut, a combined horizontal vertical cross connection sheet, a double-support safety plate and a fastening screw, wherein the double-support safety plate is provided with a rear wheel shaft hole and an upper-end fixed hole and is L-shaped; the lower end of the combined horizontal vertical cross connection sheet is hooked by a protruding part at the lower end of the double-support safety plate; the rear wheel shaft hole of the double-support safety plate is sleeved on the rear wheel shaft; the fastening screw passes through the upper-end fixed hole to fix the double-support safety plate on the combined horizontal vertical cross connection sheet; and the double supports are arranged on the rear wheel shaft, and the rear wheel fastening nut is tightly screwed. Compared with the prior art, the device has the advantages of enhancing safety, preventing the combined horizontal vertical cross connection sheet from falling due to an enlarged opening, and the like.
Description
Technical field
The present invention relates to a kind of Electrical Bicycle safety device, especially relate to a kind of Electrical Bicycle trailing wheel double bracing safety device.
Background technology
The motor and the double bracing of Electrical Bicycle are installed on the chain stay.Because battery-driven car is propped up in double bracing at ordinary times in use, if this moment, battery-driven car was uploaded weight, weight all can act in the double bracing contact pin; Under the effect of lever principle, pull the lower end of the flat upright fork-join sheet of vehicle frame easily, cause trailing wheel loosening; Can't ride; As shown in Figure 1, wherein A portion is a failure mode, and Kai Dakou can not use.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of safe Electrical Bicycle trailing wheel double bracing safety device to be provided.
The object of the invention can be realized through following technical scheme:
A kind of Electrical Bicycle trailing wheel double bracing safety device comprises double bracing, hind axle, trailing wheel clamp nut, the flat upright fork-join sheet of disjunctor, it is characterized in that; Also comprise double bracing safeguard, holding screw, described double bracing safeguard is provided with trailing wheel axis hole, upper end fixed orifice, and described double bracing safeguard is L shaped; Its lower end protrusion catches on the lower end of the flat upright fork-join sheet of disjunctor; The hind axle borehole jack of described double bracing safeguard is on the arbor wheel of back, and described holding screw passes the upper end fixed orifice, and the double bracing safeguard is fixed on the flat upright fork-join sheet of disjunctor; Described double bracing is contained on the hind axle, tightens the trailing wheel clamp nut.
The thickness of described double bracing safeguard is 2～4mm.
The following advantage of following distal process of described double bracing safeguard:
Flat to found out minister's degree be 3～5mm disjunctor through the double bracing safeguard.
Compared with prior art, the present invention has flat upright fork-join sheet, trailing wheel and double bracing and links into an integrated entity, and has strengthened safety, prevents that the flat upright fork-join sheet opening of disjunctor from increasing and come off.
