Abstract
The utility model relates to a demountable and foldable three-wheeled cart which mainly comprises a bicycle and a cart. The utility model is characterized in that the vehicle frame of the bicycle is divided into a front vehicle frame and a back vehicle frame; pin tightening screws are used to fix the front and the back vehicle frames; by using the pin tightening screws, the back vehicle frame of the bicycle and the vehicle frame of the cart which are fixed with each other can form a three-wheeled cart, and the vehicle frame of the cart can be folded; so the width of the vehicle frame is reduced, and the convenient storage is realized. The utility model is suitable for single-person riding and is also suitable for person-loading and goods-loading. The demountable and foldable three-wheeled cart is a manpower vehicle which is suitable for family.
Description
The utility model relates to a kind of bicycle and two-wheel hand barrow, relates to a kind of three-wheel vehicle simultaneously again.
At present, the trishaw of this use and bicycle can not be dismantled and fold, and therefore be not easy to move into indoor storage, and it are bigger to deposit floor area.Especially for general family, deposit and thisly can not dismantle folding three-wheel vehicle and bicycle, just more feel difficulty.
The purpose of this utility model is can dismantle folding three-wheel vehicle in order to provide a kind of.Another purpose of the present utility model is can be disassembled into two-part bicycle for a kind of.The utility model is to realize this purpose by the structure that changes vehicle frame, so that deposit conveniently.
The utility model is made by a bicycle and a barrow.Its architectural feature is vehicle frame two parts before and after the vehicle frame of bicycle is divided into, and front vehicle frame is to form one by front fork (8), cant beam (6) and the square beam of being with handlebar by welding.Back vehicle frame is had a lock screw by standpipe (1), camber beam (3), end fork (4) and the bottom side of upright fork (2), upright saddle square hole crossbeam is formed one by welding axle sleeve, in the square hole of the square hole crossbeam (5) of square crossbeam (7) the insertion back vehicle frame of front vehicle frame, fix by the lock screw on it again, refill the foot-operated rotating mechanism of front and back wheel and chain at last, just can form a complete detouchable bicycle.
The vehicle frame of barrow is divided into symmetrical two parts, by angle bar (11) and screw shaft (10) the movable binding of the two-part middle standpipe of vehicle frame (22) is one.The upper lateral tube (24) of side and lower transverse tubule (25) respectively are made up of two transverse tubes before and after the every part of vehicle frame.Between two transverse tubes, flexibly connect, two transverse tubes can be folded with rivet (12).About the middle pipe support (26) of bottom of frame is gone up by bearing pin, respectively connect a base plate (14), two base plates can upwards be started.Weld a tilted supporter (15) in the rear end of vehicle frame, tilted supporter (15) upper end is by the solid handlebar (9) of locking.Midway location is installed two pedestals (17) in vehicle frame (26) bottom, is connected one one end by central siphon (19) with bearing (18) and has axle sleeve (20) between two pedestals (17), and the other end has the swivel arm (16) of square hole and lock screw.Two front-wheels can form a hand barrow by the both sides that transverse axis is installed in vehicle frame.
One end of a short square beam (21) is inserted in the square hole of swivel arm (16) of hand barrow, its other end is inserted in crossbeam (5) square hole of back vehicle frame of bicycle after regulating vehicle body length distance, with the lock screw fixation of each square hole crossbeam, just can form a trishaw again.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a bicycle structure scheme drawing of the present utility model, Fig. 2 is a trolley structure scheme drawing of the present utility model, and Fig. 3 is the structural representation of three-wheel vehicle, and Fig. 4 is plate shaped body frame structure for automotive scheme drawing, Fig. 5 is a platform shape body frame structure for automotive scheme drawing, and Fig. 6 is the structural representation of vehicle frame folding state. are wherein: (1) saddle stand pipe, (2) vertical fork, (3) frame pipe in short square beam (22) standpipe (23) wheelchair circle (24) upper lateral tube (25) lower transverse tubule of camber beam (4) end fork (5) square hole crossbeam (6) cant beam (7) square beam (8) front fork (9) handlebar (10) screw shaft (11) angle bar (12) rivet shaft (13) bearing pin (14) base plate (15) tilted supporter (16) cursor (17) pedestal (18) bearing (19) axle (20) axle sleeve (21) (26)
Implementation method of the present utility model is fairly simple, and wherein the handlebar of bicycle (9), seat saddle, front-wheel, trailing wheel, chain pedal transmission mechanism and retaining brake can be purchased the ready-made gauge member of system.Have only the vehicle frame part to make, promptly can be made into a detouchable bicycle according to characteristics of the present utility model.The wheel of barrow of the present utility model can be purchased the wheel of bicycle, also can use two wheels on the wheelchair, and its vehicle frame need be made according to architectural feature of the present utility model.Bottom of frame can be made plate shaped (as Fig. 4), also can be made into leave from office shape (as Fig. 5), simultaneously for easy to use, can also be equipped with two in the vehicle frame front bottom end of hand barrow and turn to steamboat.
When not using this three-wheel, the lock screw that can become flexible on the swivel arm (16) makes swivel arm (16) separate with main beam transverse (21), just can be used as hand barrow and use, if the front-wheel of this three-wheel vehicle installs is two wheelchairs wheels, just can be used as wheelchair and use this moment.When not using, base plate (14) upwards can be started, because the standpipe (22) of side or transverse tube (24) all are to flexibly connect before and after the stroller frame, so just collapsible with hand to the vehicle frame that the vehicle frame center position promotes a side a little, fold afterwards so that deposit.
The Rotation With Changing of this three-wheel vehicle is finished by swivel arm (16) to action, therefore handlebar (9) is fixing by lock screw with the back tilted supporter (15) of stroller frame, so left or turn right, when rotating handlebar (9), its vehicle frame also will rotate thereupon.Because the axle sleeve (20) of swivel arm (16) is connected between the middle pedestal (17) in car bottom by axle (19) and bearing (18), be that rotating shaft is along with the rotation of handlebar (9) is rotated again so whole vehicle frame can form with axle (18).
After having dismantled before and after the three-wheel vehicle, if think by bike, can extract out crossbeam (5) square hole with main beam transverse (21) vehicle frame behind bicycle, square beam (7) with front wheel frame inserts in crossbeam (5) square hole of back vehicle frame again, and lock screw fixed, just can use.
The handlebar of three-wheel vehicle and bicycle (9) can use one mutually.Because this three-wheel vehicle can dismantle and fold,, can be used as the use of cyclist's go-cart and wheelchair simultaneously again so deposit more conveniently.
