Abstract
The utility model relates to a trailing wheel dual-gripper safety device, comprising a dual-gripper, a trailing wheel shaft, a trailing wheel fastening nut, a conjoined rear chain stay splicing, a dual-gripper safety plate and a fastening screw. The L-shaped dual-gripper safety plate is provided with a trailing wheel shaft hole and an upper fixing hole, and the lower part of the conjoined rear chain stay splicing is hooked to the lower projecting part of the dual-gripper safety plate. The trailing wheel shaft hole is sleeved on the trailing wheel shaft. The fastening screw traverses through the upper fixing hole, and fixes the dual-gripper safety plate on the conjoined rear chain stay splicing. The dual-gripper is disposed on the trailing wheel shaft and is capable of screwing up the trailing wheel and fastening the screw. Compared with prior art, the utility model has advantages of enhancing safety, and preventing a conjoined rear chain stay splicing from falling off due to the increase of the opening.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle safety device, especially relates to a kind of 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, easily the lower end of the flat upright fork-join sheet of vehicle frame is pulled, 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 purpose of this utility model is exactly to provide a kind of safe trailing wheel double bracing safety device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of trailing wheel double bracing safety device, comprise double bracing, hind axle, the trailing wheel clamp nut, the flat upright fork-join sheet of disjunctor, it is characterized in that, also comprise the double bracing safeguard, holding screw, described double bracing safeguard is provided with the trailing wheel axis hole, the upper end fixed orifice, 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, described holding screw passes the upper end fixed orifice, the double bracing safeguard is fixed on the flat upright fork-join sheet of disjunctor, and 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 lower end tab length of described double bracing safeguard is 3～5mm.
Compared with prior art, the utlity model has flat upright fork-join sheet, trailing wheel and double bracing and link into an integrated entity, strengthened safety, prevent that the flat upright fork-join sheet opening of disjunctor from increasing and come off.
