Abstract
The invention discloses a spare wheel for a rear wheel of a two-wheeled vehicle. The spare wheel comprises a support, rollers and a connection shaft, the connection shaft is provided with right-angled bent portions, the rollers are arranged at the right-angled bent portions, the connection shaft is arranged at the bottom of the support and capable of rotating around a connection point, and a retaining rod is arranged at the bottom end of the support. The spare wheel for the rear wheel of the two-wheeled vehicle enables a bicycle or an electric bicycle to be conveniently pushed to run when a tire is damaged, and is simple and practical in structure.
Description
Technical field
The present invention relates to a kind of two-wheel car trailing wheel Das Reserverad, be mainly used in the foot-supporting frame of bicycle or storage battery car.
Background technology
After the tire gas leakage, have only and carry out by force or bear away behind ordinary bicycle or the storage battery car, so very inconvenient, possibly cause secondary to damage simultaneously to the Tire & Tube of tire.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned existing existence, the purpose of this invention is to provide a kind of two-wheel car trailing wheel Das Reserverad, it can be carried out after tire gas leakage easily.
Technical scheme: for realizing the foregoing invention purpose, the present invention adopts following technical scheme: a kind of two-wheel car trailing wheel Das Reserverad comprises support, roller and connecting shaft; Said connecting shaft is provided with right angle bends; This right angle bends is equipped with roller, and said connecting shaft is located at frame bottom and can rotates around point of connection, and the bottom of said support also is provided with lever; And lever is positioned at connecting shaft top, and the Flexible Connector through the pretension setting is connected between connecting shaft and the support simultaneously; When the two-wheel car trailing wheel just often, the restoring force of roller through Flexible Connector is supported on the lever top, has spacing with ground, promptly the right angle bends on the connecting shaft all is inwardly to be in, roller is collected in the inside can not influence normal use; Can not cruising the time, roller be pushed into the lever below when two-wheel car bad tire of trailing wheel, contact with ground, alternative two-wheel car trailing wheel goes; Promptly put down foot-supporting frame, break the rotation connecting shaft off with the fingers and thumb outwardly, this moment roller is exposed and land, thereby can conveniently the gas leakage vehicle be pushed away away by roller with the right angle bends of connecting shaft.
As preferably, Flexible Connector is a spring.
As preferably, said right angle bends also is provided with retaining and colludes, thus the rotation connecting shaft make retaining collude can be firm the lever that entangles, improve the steadiness of connecting shaft.
Beneficial effect: compared with prior art, the present invention has the following advantages: bicycle or storage battery car still can easily be carried out when breaking tire, and simple in structure, practical.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of the present invention under the damaged situation of back tire;
Fig. 4 is the left view of Fig. 3.
Wherein, support 1, roller 2, connecting shaft 3, right angle bends 4, lever 5, retaining collude 6.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Shown in Fig. 1～4, a kind of two-wheel car trailing wheel Das Reserverad comprises support 1, roller 2, connecting shaft 3 and lever 5; Said connecting shaft 3 is a bent axle, and two right angle bends 4 just are set on d-axis, on this right angle bends 4, roller 2 is set; And the two ends of this connecting shaft 3 are installed in the bottom of support 1, and rotatable, between connecting shaft 3 and support 1, back-moving spring is set simultaneously; Like this, the right angle bends 4 of normal circumstances connecting shaft 3 is roller 2 is collected in inside and can influence vehicle and normally use inwardly, when needs; Put down foot-supporting frame; And rotating shaft makes right angle bends 4 outwardly, and roller 2 came out and can replace the rolling that lands of former trailing wheel this moment, and said in addition lever 5 is installed in the bottom of support 1.As improvement, retaining is set on right angle bends 4 colludes 6, thus fixedly connecting shaft 3 that can be more firm, thus and then fixed idler whell 2.
