Abstract

The invention belongs to the technical field of the bicycle and relates to a pedal hand-pulled bicycle. The pedal hand-pulled bicycle is characterized in that the lower part of a handle upright casing is welded with the periphery of one side of a bearing; an upper stop-gear and a lower stop-gear are separately connected with a front fork shaft; the two sides of a connection steel plate between the upper stop-gear and the lower stop-gear are separately welded with the sides of two U-shaped hooks; the bearing is arranged between the U-shaped hooks, the both ends of the bearing shaft extend out of the U-shaped hooks and are fastened and connected by nuts; the lower end of the handle upright casing is connected with a radius-changing rod through a stay; and one end of the stay is connected with the endpoint of the radius-changing rod, and the other end is fixedly connected with and wound in the rim groove of a coil spring assembly through a guide wheel and the coil spring assembly. The invention has the following beneficial effect that when riding the bicycle, the rider pulls the handle; the handle upright casing can rotate around the bearing shaft in the limit range of the upper and lower stop-gears; and the bearing and the U-shaped hooks are integrated with the front fork shaft through the upper and lower stop-gears, thus the bicycle can operate flexibly at a corner and have no hidden danger. Compared with the existing bicycle, the pedal hand-pulled bicycle has lower production cost.

Description

A kind of pedal hand-pulled bicycle

Technical field

The invention belongs to technical field of bicycles, relate to a kind of pedal hand-pulled bicycle, relate in particular to the patent No. 200720001556.8, name is called the steering mechanical structural development of the Chinese patent of pedal hand-pulled bicycle.

Background technology

Bicycle is the vehicle, the fitness tool that people commonly use, and has environmental protection, the plurality of advantages such as pollution-free, easy to use.But long-term travel, against the wind or climbing still feel effort when riding, the shortcomings such as physical consumption is large, speed is fast are not arranged.And only having both feet to trample motion when riding, both hands keep transfixion basically, in the both hands numbness of often enduring cold cold season.

For the problems referred to above, the patent No. is 200720001556.8, and name is called the Chinese patent of pedal hand-pulled bicycle, can be simultaneously by riding, pull the driven in two modes bicycle.The end of the pulling luffing car of this pedal hand-pulled bicycle fork is equipped with and turns to semicircular ring, turns between semicircular ring and the ultrasonic transformer to be connected by butt hook.When not only complex structure, and bicycle handle bar turns to, turn to semicircular ring easily and adjacent miscellaneous part generation grazing, greatly affected alerting ability and safety that bicycle when turning is ridden.

Summary of the invention

The technical problem to be solved in the present invention is to improve the steering hardware of bicycle, and the pedal hand-pulled bicycle of a kind of simple in structure, flexible operation, riding safety is provided.

For achieving the above object, the technical solution used in the present invention is: a kind of pedal hand-pulled bicycle, comprise vehicle frame, front and back wheel, ultrasonic transformer, place the vehicle frame right side bicycle chain and with the flying of hind axle assembly connection, it is characterized in that: the neighboring of handle vertical rod sleeve bottom and bearing one side is welded to connect fixing, upper stop, lower stop is connected with front fork shaft respectively, described upper stop, junction steel plate dual-side between the lower stop is welded to connect fixing with U-shaped hook side respectively, described bearing places between two U-shaped hooks, and the two ends of described bearing axle are stretched out U-shaped hook and connected by fastening nuts; Described handle vertical rod sleeve lower end by stay cord be connected with described ultrasonic transformer, withdrawal cord one end is connected with described ultrasonic transformer end points, the other end flies assembly set through track adjusting wheel wheel rim groove and disc spring and captives joint and be wrapped in the wheel rim groove that described disc spring flies assembly set.

Described handle vertical rod sleeve upper end is connected with the vertical rod lower sleeve formula of tee T handle, screw threads for fastening is fixed.

Described disc spring flies assembly set and places the bicycle rear axle left side.

The invention has the beneficial effects as follows: pull handle when riding, the handle vertical rod sleeve can in the scope that stop is placed restrictions on up and down, rotate around bearing axle; Bearing, U-shaped hook are connected with front fork shaft by stop up and down, and there is not potential safety hazard in the flexible operation of riding that turns round; In addition, the present invention is simple in structure, and many with existing Universal bicycle spare, productive costs is low.

Description of drawings

Below in conjunction with drawings and Examples, the invention will be further described.

Fig. 1 is structural representation of the present invention;

Fig. 2 is that the A of Fig. 1 is to view.

Among the figure, 1-tee T handle; 2-handle vertical rod sleeve; The upper stop of 3-; 4-U type hook; The 5-bearing; Stop under the 6-; The 7-stay cord; The 8-front fork; The 9-ultrasonic transformer; The 10-withdrawal cord; The 11-track adjusting wheel; The 12-disc spring flies assembly set.

The specific embodiment

Fig. 1 and Fig. 2 are structural representation of the present invention, by diagram as seen:

A kind of pedal hand-pulled bicycle, comprise vehicle frame, front and back wheel, ultrasonic transformer 9, place the vehicle frame right side bicycle chain and with the flying of hind axle assembly connection, it is characterized in that: the neighboring of handle vertical rod sleeve 2 bottoms and bearing 5 one sides is welded to connect fixing, upper stop 3, lower stop 6 are connected with front fork 8 axles respectively, junction steel plate dual-side between described upper stop 3, the lower stop 6 is welded to connect fixing with U-shaped hook 4 sides respectively, described bearing 5 places between two U-shaped hooks 4, and the two ends of described bearing 5 axles are stretched out described U-shaped hook 4 and connected by fastening nuts; Described handle vertical rod sleeve 2 lower ends by stay cord 7 be connected with described ultrasonic transformer 9, withdrawal cord 10 1 ends are connected with described ultrasonic transformer 9 end points, the other end flies assembly set 12 through track adjusting wheel 11 wheel rim grooves and disc spring and captives joint and be wrapped in the wheel rim groove that described disc spring flies assembly set 12.

The vertical rod lower sleeve formula connecting thread of described handle vertical rod sleeve 2 upper ends and tee T handle 1 is fastening fixing, and the handle height can need to regulate by bicyclist's height.

Described disc spring flies assembly set 12 and places the bicycle rear axle left side.

Pedal hand-pulled bicycle of the present invention, foot-operated riding fixed the transmission that flies of assembling by the bicycle chain and the hind axle right side that place the vehicle frame right side at ordinary times, is as good as with existing commercially available cycling mode; Go up a slope or against the wind, in the time of need pulling the acceleration of handle power-assisted, be wrapped in withdrawal cord in the wheel rim groove that described disc spring flies assembly set 12 by pull, the transmission that flies that makes disc spring fly assembly set 12 is accelerated, when pushing away before the tee T handle 1, because the elastic force of disc spring, disc spring flies to fly back in the assembly set 12 and restores the beginning state, meet next time pull, light and fast travels; Particularly the present invention has done improvement to the steering structure that name is called the Chinese patent (patent No. 200720001556.8) of pedal hand-pulled bicycle, with bearing 5, U-shaped hook 4 by the steering structure that connects as one of stop and front fork 8 axles up and down, replace the semicircular ring steering structure, not only simple in structure, and greatly improved pedal hand-pulled bicycle turn round flexibility of operation and safety when riding.
