Abstract
The utility model relates to a folding-typed three-wheel device for a bicycle. One side of an auxiliary wheel is provided with a folding leg which is composed of brackets, and longitudinal hooks. The two brackets are connected by T-shaped pins and a slideway, and each bracket is positioned by the longitudinal hooks. The lower end of an L-shaped supporting rod is fixedly connected to the axle of the auxiliary wheel, and the upper end of the L-shaped supporting rod is hinged on the upper cross rod of the bracket whose upper end can be separated from the outer side of a rear wheel. The lower end of the support frame whose upper end can be separated from the outer side of a rear wheel is hinged with a support frame which is used for fixing on the rear wheel and a rear fork. The upper cross rod of the other bracket is hinged with a support dog which is used for fixing with the supporting rod of a school bag frame. The upper side of the longitudinal hooks is fixed with a bicycle hopper. The utility model has the advantages of foldability, small occupation area, and double purpose for carrying people and carrying article. The conversion between the two-wheel and the three-wheel is convenient, and no tool is required.
Description
The utility model is a kind of exclusive annex of bicycle that belongs to, and is a kind of carrying apparatus.
A kind of bicycle of selling on the market set up three wheel apparatus be at the bicycle rear lateral surface cross bar, wheel and support thereof are set, fixing wagon box above the cross bar.These all form with bolted connection or riveted joint, and are not quick detachable, can not fold, and park to take up an area of greatly, are difficult to loaded with articles, and practicality is little.
In view of the foregoing, the purpose of this utility model provides and a kind ofly can convert bicycle to three-wheel vehicle at any time, also can restore a kind of three wheel apparatus for bicycle at any time.
The purpose of this utility model is achieved in that the side at wheel, be provided with a folding stand of forming by two supports and horizontal hook thereof, be connected with the slide hinge form with chute by T type pin between two supports, horizontal hook be hinged on a upper end can leave on the cross tube of support of trailing wheel lateral surface, and can clasp joint on the cross tube of another support.One
The lower end of shape pole is fixed on the axle of wheel, its slide hinged cross tube one that can leave the support of trailing wheel lateral surface in the upper end in upper end, and the lower end of this support is hinged bracing frame is used for fixing on the axle and back vent of bicycle rear lateral surface.Slide hinged one is supported dog on another support cross tube, is used to be fixed in the pole of bicycle schoolbag frame, and its sheer pole can be supported on
On the shape bar.Fixing wagon box on horizontal hook.
The upper end is fixed on the support on the schoolbag frame, and its sheer pole front end can connect a retractable foot rest.Wagon box can be the U-lag body.Can connect in U-lag body back that an energy rotates along groove, and can erect the U-lag body of locating with as seat back.
The utility model is collapsible, takes up an area of for a short time, and manned loading two is suitable, and two, the three-wheel convenient functional conversion, do not need advantages such as tool operation.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the back view that Fig. 1 folds;
Fig. 3 is two U-lag bodies (wagon box) lateral plan that links to each other.
With reference to Fig. 1, Fig. 2, wheel 10 is the bicycle quick of φ 50cm, is provided with a folding stand of being made up of support 3,4, horizontal hook 7 in its side.Between two supports 3,4 by the T type pin that is fixed on a support 3 or 4, constitute rotation and sliding block joint with the chute of another support 4 or 3, hinged two horizontal hooks 7 on support 3 cross tubes, its can clasp joint on the cross tube of support 4, play the fixed pedestal folding stand.Folding stand is all used tubular steel except that cross tube.
Shape pole 9 upper ends are slide hinged on support 3 cross tubes, between two horizontal hooks 7, it not only can be rotated and slidably on cross tube, folding after, wheel 10 is raised and breaks away from ground, at this moment can with
The upper end edge cross tube of shape support 9 slides backward, and makes the bicycle step that bigger activity space be arranged.
The lower end of shape pole 9 is fixed on the axle of wheel 10, plays fixedly wheel 10, and the axis hole of the affixed wheel 10 in its lower end can be provided with 1~4, and pitch-row is 2.5cm, to adapt to the use of different size bicycle.The lower end of support 3 is hinged bracing frame 8 is used for fixing on the axle and back vent of bicycle rear 1 lateral surface.The cross tube of support 4 is slide hinged one support dog 5, be used to be fixed in schoolbag frame pole 6, support the slip of dog 5 on support 4 cross tubes, solved the different connection difficulty in different bicycle schoolbag frame poles 6 positions.But in the tubular sheer pole front socket of support 4 a retractable leg rest frame 2.Horizontal hook 7 top fixedly wagon boxes 11.Wagon box 11 can be the U-lag body, also can connect in U-lag body back that crossheading rotates, and the U-lag body 12 that can erect the location make backrest usefulness when manned, this locatees turning joint realization by a turning joint and another, as shown in Figure 3.
Three-wheel recovers the operating process of bicycle: on one side as long as wagon box 11 dug by vehicle body voluntarily the horizontal hook 7 that is fixed together with it is thrown off with the cross tube of support 4, will again
Shape pole 9, outwards pull breaks away from the sheer pole of itself and support 4 downwards, then wheel 10 and folding stand is pushed to bicycle rear together, wheel 10 promptly is raised, and wagon box 11 rested on the schoolbag frame, fix and just finished folding process, recovered the bicycle state.Above-mentioned bicycle is converted to three-wheel, and just the inverse process of aforementioned operation is also very simple and direct.
