Abstract

The utility model relates to a bicycle spare wheel. The bicycle spare wheel comprises a supporting plate, a pendulum bar and a rolling wheel component; one end of the supporting plate is provided with a fastening piece which is fixedly connected with a bicycle frame, the pendulum bar is connected on the supporting plate in a swinging way; the rolling wheel component is connected with the bottom end of the pendulum bar. In normal riding, the pendulum bar uplifts, which causes the rolling wheel to be suspended in the air, thus normal driving can not be affected; when tire burst occurs, a user can quick pull the pendulum bar straight and allows the pendulum bar to be in the same straight line with the supporting plate along the vertical direction; in this way, the rolling wheel component is in contact with the ground for rolling, while the punctured tire is suspended in the air, thus the user can push an electric bicycle easily. The bicycle spare wheel of the utility model has the advantages of reasonable structure, convenient usage and fine effect and can be put into use within one minute after tire burst occurs. Users can push the bicycle easily and roll compacting between a tire tube as well as a cover tire and a steel ring during walking can be avoided. The tires are protected from being further damaged.

Description

The bicycle Das Reserverad

Technical field

The utility model relates to a kind of bicycle accessories, especially a kind of when Electrical Bicycle is blown out as standby bicycle Das Reserverad.

Background technology

Existing Electrical Bicycle in use can be run into the awkward situation that halfway is blown out unavoidably, when pushing away flat tire, the user finds when repairing the stand, often because the distance of flat tyre walking is long, the inner tube of a tyre has galled under the rolling roll compacting of steel ring together with cover tire, have to renew again, economic loss and physical demands are depressing.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of bicycle Das Reserverad that is fixed on the cycle frame is provided, and solves the problem that present bicycle does not have Das Reserverad, thereby the bicycle inconvenience that brings of blowing out is eliminated basically.

The utility model solves the technical scheme that its technical matters adopts: this bicycle Das Reserverad, comprise stay bearing plate, fork, roll wheel assembly, and stay bearing plate one end is provided with the fastener affixed with cycle frame, and fork is connected on the stay bearing plate in the mode that can swing; Roll wheel assembly is connected the bottom of fork.When normally riding, fork lifts, and roll wheel assembly is suspended in the air, does not influence cruising; After blowing out, the user can very fast manual stretching fork, makes itself and stay bearing plate be the straight line of vertical direction, like this, the roll wheel assembly rolling that just lands, thus be suspended in the air blowing out, and the user just can carry out Electrical Bicycle like a cork.

The effect that the utility model is useful is: the utility model is rational in infrastructure, and is easy to use, effective.Blow out take place after, can one minute with interior place in operation, make user's go-cart light, and avoided the roll compacting of Tire ﹠ Tube and steel ring in the process of walking, protect tire no longer to strengthen damage rate.

Description of reference numerals: stay bearing plate 1, chute 1-1, positioning groove 1-2, swinging chute 1-3, extension spring 2, jam nut 3, wheel body 4, wheel fork 5, fork 6, the first pin 6-1, the second pin 6-2, fastener 7, bearing 8, screw rod 9, nut 10, wheel 11, level shelves 12, groove 13, wheel shaft 14.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to accompanying drawing: this bicycle Das Reserverad, comprise stay bearing plate 1, fork 6, roll wheel assembly, stay bearing plate 1 one ends are provided with the fastener 7 affixed with cycle frame, and this fastener 7 is pressing plates, and pressing plate is by the side of screw retention at stay bearing plate 1; Pressing plate is provided with the groove 13 that is complementary with vehicle frame, and stay bearing plate 1 also is provided with corresponding grooves 13 with the pressing plate opposite position.By pressing plate, stay bearing plate 1 can be fixed on the vehicle frame, specifically be to be fixed on the level shelves 12 that are used to install wheel 11 wheel shafts.

Fork 6 is connected on the stay bearing plate 1 in the mode that can swing.Fork 6 itself and stay bearing plate 1 bonded assembly end are provided with the first pin 6-1, and this first pin 6-1 is interspersed in the chute 1-1 of stay bearing plate 1; Fork 6 is provided with the second pin 6-2 below the first pin 6-1, this second pin 6-2 is interspersed in the swinging chute 1-3 of stay bearing plate 1; It is the circular arc in the center of circle that swinging chute 1-3 is with chute 1-1, and the inner end of swinging chute 1-3 extends upward and forms a positioning groove 1-2, and this positioning groove 1-2 aims at chute 1-1 and is straight line with chute 1-1; Also be provided with extension spring 2 on the stay bearing plate 1, an end of this extension spring 2 is fixed on the stay bearing plate 1, and the other end is fixed on the fork 6.Like this, fork 6 can be the axle center with the first pin 6-1, swings along swinging chute 1-3.When fork 6 was rocked to the perpendicular state of stay bearing plate 1, roll wheel assembly was by unsettled, and can locate by extension spring 2 this moment, made fork 6 keep the state perpendicular with stay bearing plate 1.When fork 6 is rocked to straight line with 1 one-tenth vertical direction of stay bearing plate, roll wheel assembly is put down with ground and is contacted, and this moment, the second pin 6-2 was pushed in the positioning groove 1-2, added the tensile force effect of extension spring 2, just can position, fork 6 can not rocked in the horizontal direction.The length of chute 1-1 is identical with the length of positioning groove 1-2, when the second pin 6-2 moves in the positioning groove 1-2, guarantees that the first pin 6-1 has corresponding displacement.

Roll wheel assembly is connected the bottom of fork 6.Roll wheel assembly comprises wheel fork 5, wheel body 4, and wheel fork 5 is provided with wheel shaft 14, is provided with bearing 8 in the wheel body 4, and wheel body 4 is enclosed within on the wheel shaft 14 by this bearing 8.The upper end of wheel fork 5 is provided with screw rod 9, and the bottom of fork 6 is provided with nut 10, and screw rod 9 is tightened on 10 li on nut, and screw rod 9 is provided with jam nut 3.Adjusting screw(rod) 9 one is in order to regulate adjustable height, and two in order to adjust the directions of wheel body 4, makes it guarantee the Das Reserverad direction and blow out consistently, and it is smooth to roll forward.

Fork 6 relies on the slip of pin, stay bearing plate 1 carries out the revolution of 90 degree relatively, the structure of stay bearing plate 1 upper hopper chute, positioning groove adds that the tensile force of extension spring 2 guarantees that fork 6 can be fixed at two end positions, even under vibrational state, still fixedly relative position is constant.Under normal riding condition, fork 6 is vertical mutually with stay bearing plate 1, and wheel body 4 is suspended in the air, and Electrical Bicycle rolls with the air-inflation tyre of self; After blowing out, the user can spur fork 6, makes the straight line of 1 one-tenth vertical direction of itself and stay bearing plate, thereby makes wheel body 4 rolling that lands.The utility model Design of device height is enough to be suspended in blowing out aerial, thereby avoided in the process of moving ahead tyre rim to the roll compacting of rubber tyre, and the height of wheel fork 5 can regulate by the screw rod 9 of wheel fork 5 upper ends, to adapt to the Electrical Bicycle of multiple model.Ball bearing of main shaft 8 in the wheel body 4 guarantees that the user can carry out Electrical Bicycle like a cork.

After the reparation of blowing out, the user makes fork 6 and stay bearing plate 1 return to mutual plumbness with pulling movable pendulum bar 6, and at this moment, wheel body 4 has suspended in mid air again, and the user can continue to ride with electric power.The action of pulling fork is simple, and whole process just can be settled in one minute.The height of the standby wheel body 4 of each Electrical Bicycle and direction only need to adjust when this device is installed and once get final product, and be very convenient.
