Description

Multifunctional combination domestic trolley

The utility model relates to a kind of bicycle that is convertible into or changes system into the other types vehicle, especially a kind of multifunction combined home vehicle.

The bicycle of Xiao Shouing, wheelchair, and all effects of each tool self of forward and backward seat three-wheel vehicle in the market, but function is more single; The type of attachment of all kinds of front and back seat formula three-wheel vehicle is generally: bolt-type, directly three kinds of fixed type, hinge types, and these draw bails are more complicated on the whole, and external form is not attractive in appearance, and stability is relatively poor.

The purpose of this utility model provides a kind of simple in structure, and universal performance is good, and is safe in utilization comfortable, and mounting or dismounting are convenient, and appearance and modeling U.S. both can ride as bicycle, can make people's goods dual-purpose tricycle again and make, and also can work as the multifunction combined home vehicle that hand barrow is used.

The utility model be by before the bicycle partly, back part, wheel chair type front stall part, ramp type coupling mechanism, connection rotating mechanism, and compositions such as cardan wheel, handrail, tread plate.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 connects the rotating mechanism structural representation for the utility model.

Fig. 3 is a part structural representation before the utility model bicycle.

Fig. 4 is that the utility model coupling mechanism K is to structural representation.

Fig. 5 is that the utility model front stall lock B is to structural representation.

Fig. 6 is the utility model front stall brake structure birds-eye view.

The utility model has adopted existing woman style U type bicycle structure, and bottom camber beam, it is divided into front and back two partly (21), (11), the one ramp type coupling mechanism (9) by concave, convex inclined-plane (24,25) and guide finger, screw (22,23) formation is set at the camber beam place, as Fig. 4, front and back are partly separated or connection by coupling mechanism.

Front stall partly adopts wheel chair type, and cushion (6), back cushion (7), handrail (5), main wheel (13), cardan wheel (2), block material net (3), tread plate (1) etc. are promptly arranged.Wherein, be provided with by quick-release screw (15), back plate (14), locating dowel pin and cover (16), strengthen gusset (18), connection mainboard (20), steel ball and go up the connection rotating mechanism (12) that lower blocking bowl (17) constitutes at front stall main wheel (13) axletree center position, realize rotating by steel ball, last lower blocking bowl, realize connecting fastening by quick-release screw, locating dowel pin, cover.Front stall lock (11) adopts pincerlike lock, left and right wheels is respectively joined 1 cover, its principle is: lock and brake lever all are positioned on the front stall, steel cable and brake lever are connected as a single entity, the centre of (26) there is a fixing guide wheel of steel cable (27) in that integral body is curved, as long as with brake lever external force upward movement, affect pincerlike lock by steel cable, can play braking function.Front stall handrail (5) is located to be fixed with and can be stretched rolling over of receipts and hold up frame (4), and tread plate (1), cushion (6) are all collapsible, and fwd cardan wheel (2) is handled to be drawn by steel cable by handle (8) and made it can reach the top to the inside again to turn an angle.Connect the main pitman that there is the ramp type coupling mechanism end in the middle of the front stall main wheel (13), conveniently with behind the bicycle partly connect or separate.

The occupation mode of this multifunction combined home vehicle can be divided into following two aspects:

Compound type: by behind the bicycle partly with front stall partly after the new special bindiny mechanism of Fig. 2, Fig. 4 connects, use with the structure of Fig. 1, this structure vehicle can singlely be ridden, and can walk front stall band of position people or band thing again.If front stall band man-hour holds up frame and tread plate to stretch out expansion, cardan wheel upwards reaches the inboard through steering unit and turns an angle away from ground; When being with thing, holding up frame, tread plate, seat cushions all can fold and put, can be with thing to ride if front stall need not be with the people.

Split type: as to be about to bicycle trailing portion and front stall coupling mechanism partly and to remove, the front stall of this moment partly can be used as hand barrow, can be with the people can be with thing again, cardan wheel again through steering unit make its down to outside rotation vertical ground firmly, when travelling comfortable steadily.Behind the bicycle partly again with bicycle before partly as Fig. 3, with the coupling mechanism connection of Fig. 4, can form a complete U type bicycle, its safety performance can reach the bicycle national standard equally.

This multifunction combined home vehicle is safe in utilization comfortable, aesthetic in appearance, universal performance is good, coupling mechanism is simple in structure, and mounting or dismounting are convenient, and the mode that can be used as bicycle, people's goods dual-purpose tricycle, hand barrow after this vehicle combined deformation is used, can satisfy adult, teenager's needs, being suitable for the elderly, mothers and sons, man and wife, baby, disabled person's use again, also can realizing electric power, manpower both and usefulness, is the more perfect desirable vehicle of a kind of function.

Claims (1)

1, a kind of multifunction combined home vehicle, by before the bicycle partly, the back partly, the wheel chair type front stall partly, and compositions such as cardan wheel, handrail, stretcher is characterized in that:

A, the forward and backward part of bicycle (21,11) are provided with a ramp type coupling mechanism (9) by concave, convex inclined-plane (24,25) and guide finger, screw (22,23) formation at the camber beam place;

B, front stall main wheel (13) axletree center position are provided with by quick-release screw (15), back plate (14), locating dowel pin and cover (16), strengthen gusset (18), connect the connection rotating mechanism (12) that mainboard (20), steel ball and upper and lower retaining bowl (17) constitute;

C, front stall lock (11) adopt pincerlike lock, and left and right wheels is respectively joined 1 cover, there is a fixing guide wheel of steel cable (27) centre of (26) in that integral body is curved;
