Abstract

The utility model relates to an improved combined three-wheel bicycle, which is formed by the combination of a bicycle and a handcart. The utility model is characterized in that the joining of the bicycle and the handcart adopts a simultaneous tension mechanism which is composed of an eccentric wheel, a clamping piece, an operating lever, and a pin rod. In order to cause the two front wheels to divert simultaneously, the front fork of the bicycle is provided with a guide wheel which is connected and used to draw a wire cable which is arranged on two front guide wheels. The front side of the guide wheel is provided with a mechanism which is compose of a draw rod, a locating ring, and a spring and is used for connecting and tensioning the wire cable. The utility model has the advantages of fast and stable ride, flexible steering, comfortable sitting, convenient disassembly and assembly, convenient carrying, and convenient placement. The utility model can carry the adult, the child, or the object of 135 kilograms. The improved combined tricycle is an ideal domestic multi-purpose tricycle for the urban dweller.

Description

Improved combined tricycle
The utility model relates to a kind of manually driven vehicle that combined by barrow and bicycle, belongs to the bicycle sciemtifec and technical sphere.
December 5 nineteen ninety the Decree of Patent Office of China compound type tricycle (utility model, application number 89220911.9), it has can close and can divide, two front-wheels such as can turn to synchronously at function, have solved three-wheel vehicle and have deposited inconvenience and move difficult problem.But, it remains in the some shortcomings part: former utility model is used for the eccentric wheel tensioner mechanism of hand barrow and bicycle butt joint, not only structure is complicated, the cost height, and it does not have the effect of opening outside the prevention clamp ring in butt joint, cause butt joint to be easy to generate to a certain degree loosening, fastness is not enough to guarantee traffic safety; Again, intrinsic synchronous steering hardware part is more, and cost is higher, and in a single day the fulcrum shaft of fan-shaped transmission levers and axle sleeve and afterbody notch have expansion because of wearing and tearing slightly with the gap that turns to driving lever, just can cause that two front-wheels slightly rock under steam, it is steady inadequately to cause riding; In addition, the former wheel carrier that is located under the hand barrow vehicle frame is fixed on the vehicle frame stage casing, and hand barrow exists when using separately if not having other people helps, and takes the defective that dumps forward easily.
The purpose of this utility model is, the eccentric wheel tensioner mechanism of two cars butt joint is carried out suitable improvement design, and so that a kind of compact conformation to be provided, cost is low, not only can backward but also can inwardly strain clamp ring simultaneously, makes the solid and reliable synchronous tensioner mechanism of two cars butt joint; Be that the synchronous steering hardware under the specification conditions improves below 20 inches or 20 inches to this vehicle bicycle front-wheel and trolley wheel simultaneously, make it become cost and decrease, the synchronous steering hardware of stable performance; Improve hand barrow, make its wheel carrier become transportable movable wheel carrier, help also and can take safety and steady thereby make hand barrow when using separately, not have other people.
The utility model is achieved in that the synchronous tensioner mechanism that is made of eccentric wheel, holding piece, joystick and pin rod etc. in the setting of cycle frame leading portion; Wherein, the side that holding piece at first contacts clamp ring is along being extratensive type, so that inwardly strain clamp ring, and can be backward but also can inwardly strain the effect of clamp ring thereby eccentric wheel is become have not only.Improvement to synchronous steering hardware is: keep be located at guide wheel (being front jocket wheel) that two preceding casters stick and around the steel rope of knot in the front jocket wheel outside original the branch, but cancel former fan-shaped transmission levers and turn to driving lever, a guide wheel (i.e. back guide wheel) is set on the bicycle front fork transverse tube in addition.Because on two car bodies of front and back guide wheel branch fashionable branch when being located at, so the binding tensioner mechanism that must constitute by pull bar, nest and spring etc. in the setting of the front side of back guide wheel.
In addition, stop the bicycle front fork right-hand rotation, must be retrofitted in the front fork rear side to brake before the bicycle wire rope for avoiding steel rope.
Improvement to hand barrow is: the bindiny mechanism that adopts draw runner, the porose formations such as clamping ring, wheel carrier spacer and spring holder in upper end wheel carrier to be connected with the hand barrow vehicle frame and can to move forward and backward.When the wheel carrier reach puts in place, spring holder just can insert wheel carrier spacer and wheel orienting piece, two front-wheels just form the support of the basic symmetry in front and back with the cardan wheel that the hand barrow vehicle frame back lower place falls, and help thereby make hand barrow not have other people when using separately, but take also safety and steady.
The utility model compared with prior art has the following advantages:
1. tensioner mechanism and synchronous steering hardware structure are compact synchronously, and cost reduces, and performance obviously strengthens, thereby make the butt joint of two cars solid and reliable, ride steadily.
2. do not have other people when hand barrow uses separately and help, but take yet safety and steady.
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is an improved type compound type tricycle External view.
Fig. 2 is synchronous tensioner mechanism constructional drawing.
1-eccentric wheel among the figure; The 2-holding piece; The 3-joystick; The 4-pin rod; The 5-clamp ring; 6-bite (this is not shown); The 7-cycle frame.
Fig. 3 is the A-A section-drawing of Fig. 2.
1-eccentric wheel among the figure; The 2-holding piece; The 3-joystick; The 4-pin rod; The 5-clamp ring; The 6-bite; The 7-cycle frame.
Fig. 4 is that back guide wheel and steel rope link the tensioner mechanism scheme drawing.
8-round bar fag end among the figure; Guide wheel behind the 9-; The 10-pull bar; The 11-nest; The 12-spring; The 13-steel rope.
Fig. 5 is synchronous steering hardware and wheel carrier bindiny mechanism scheme drawing.
Guide wheel behind the 9-among the figure; The 13-steel rope; The 14-front-wheel; The 15-front jocket wheel; 16-hand barrow vehicle frame; The 17-wheel carrier; The 18-clamping ring; The 19-draw runner; 20-wheel carrier spacer; 21-wheel orienting piece; The 22-spring holder.
By Fig. 2 and Fig. 3 as can be known, when the preceding position of shifting onto of joystick (3), the convex surface of eccentric wheel (1) and holding piece (2) all are in the front side of pin rod (4), are inserted in clamp ring (5), and joystick (3) post-tensioning puts in place, and clamp ring (5) is just by inwardly tension backward simultaneously.
As can be seen from Figure 4 and Figure 5, after the butt joint of two cars steel rope (13) intersection is walked around back guide wheel (9) rear side, again the round bar fag end (8) at steel rope (13) two ends is inserted the socket on guide wheel (9) front side, back and the pull bar (10) respectively, pull pull bar (10) and it is inserted in the nest (11), steel rope (13) just realizes linking tension with back guide wheel (9).
In addition, the front-wheel of bicycle must adopt the wheel of or close specification identical with trolley wheel, makes front jocket wheel (15) and back guide wheel (9) be in the height of basically identical, can realize turning to synchronously around knot steel rope (13).
