Abstract
The utility model relates to a wheel combined device used on a labor-saving bicycle (a vehicle for climbing stairs). The wheel combined device is composed of two sets of identical wheels, and the two sets of wheels are connected with each other by a connecting rod; each set of wheels are composed of wheels A and wheels B provided with gears, and the wheels A and the wheels B which are in a symmetrical shape are respectively provided with two wheel brackets which is fixed on a vehicle wheel disc; the other end of vehicle wheel disc is provided with a wheel and regulating screws, and the wheels A and the wheels B provided with gears are connected with each other by butterfly screws. The four wheels form a cross shape, or form a reverse V shape by overlapping two after two. With the advantages of simple structure, convenient operation, time saving, and labour saving, the utility model can adapt to various topographies.
Description
The utility model relates to a kind of wheel combination device that is used on the Labour-saving car (cart for travelling up or down stairs).
Prior art, as laborsaving cart for travelling up or down stairs (ZL 96247334.1), it is that front end at kickstand joins the four wheel mechanism of a symmetry, on the axle of four wheel mechanism, fix a flywheel, connect a cam, a handle is arranged on the cam at the middle part of kickstand, chain is to be enclosed within on the flywheel, one end of chain is connected on by a spring near the axle center of cam, and the other end of spring is associated in an end in cam axle center far away, welds one handle on the cam axial line angled with kickstand.Its structure is complicated, also laborsaving inadequately.
The purpose of this utility model will propose a kind of simple in structure, and is easy to use, labour-saving wheel combination device.
Technical solution of the present utility model:
Form by two groups of identical wheels, there is a connecting rod to connect between two groups of wheels, each group wheel is made up of the wheel B of wheel A and band gear, they are symmetry shape, and two wheel stands 1 are arranged respectively, 14, wheel stand 1, an end of 14 is the wheel dish 10 that is fixedly connected on separately, on 12, wheel stand 1, wheel 4 is housed on 14 the other end, 13, wheel stand 1,14 are provided with the set screw 9 of scalable wheel stand length, 15, wheel dish 10 on the wheel B of wheel A and band gear, 12 centre bits are equipped with a centre hole 3, geared sleeve 6, two sides of centre hole 3 and geared sleeve 6 respectively have a screw 5, gear card 7 is arranged on the geared sleeve 6, one group of gear 8 is arranged in the geared sleeve 6, centre hole 3 on geared sleeve 6 and the wheel A matches, and the wheel B of wheel A and band gear links together by two wing bolts 11, and four wheels (i.e. two wheels 4 and two wheels 3) can be criss-cross, also can two or two overlapping, be inverted v-shaped.
Advantage of the present utility model:
Simple in structure, processing ease, time saving and energy saving, can adapt to various landform and use.
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is structural representations of wheel A
Accompanying drawing 3 is structural representations of wheel B
Among the figure 1, the 14th, wheel stand (telescopic), 2, the 16th, fix screw is used for fixing support and wheel dish 10,12, and the 3rd, centre hole, 4, the 13rd, wheel, the 5th, screw, the 6th, geared sleeve, the 7th, gear card, 8 is one group of gear, 9, the 15th, set screw, the 10, the 12nd, wheel dish, the 11st, wing bolt.
Further describe technical solution of the present utility model below in conjunction with accompanying drawing:
Form by two groups of identical wheels, each group wheel is made up of the wheel B (structure as shown in Figure 2) of wheel A (structure as shown in Figure 1) and band gear, they are symmetry shape, the wheel B of wheel A and band gear respectively has two wheel stands 1,14, wheel stand 1, an end of 14 is to be separately fixed at wheel dish 10, on 12, wheel stand 1, wheel 4 is housed on 14 the other end, 13, the length of wheel stand is with set screw 9,15 adjustings, general length is fixed with the height of stairway step, wheel dish 10 is arranged on the wheel A, a centre hole 3 is arranged in the middle of wheel dish 10, it matches with the set geared sleeve 6 in wheel B center of band gear, that is to say that geared sleeve 6 is stuck in this centre hole 3, two sides of centre hole 3 and geared sleeve 6 respectively have a screw 5, the wheel B centre bit of band gear is equipped with a geared sleeve 6, gear card 7 is arranged on the geared sleeve 6, one group of gear 8 is arranged in the geared sleeve 6, gear 8 is proal, wheel is in case backward, gear 8 is the stop motion, it is by gear card 7 controls that are arranged on the geared sleeve 6, when wheel 4,13 are obstructed or backward, gear card 7 is just fallen in the gear 8, stop gear 8 motions, wheel just can not be forward, two wing bolts 11 link together by the wheel B of the screw 5 among the wheel B of wheel A and band gear with wheel A and band gear, four wheels on the wheel B of wheel A and band gear can be criss-cross, and are also can two or two overlapping, are inverted v-shaped.Be that two groups of wheels are linked together with a connecting rod during use, two groups of wheels must be symmetry shape in use, and four wheels in one group of wheel can be criss cross, wherein have two wheels to land, also have two wheels towards the space (non-landing), as shown in Figure 1.When wheel 4 or 13 is obstructed (backward), gear card 7 is just fallen in the gear 8, stop gear 8 motions, wheel just can not be forward, if firmly pull a cart (startup wheel) forward, non-two wheels that land just forward (Gao Po) roll and land, wheel just steps a stage, constantly pull a cart forward just constantly to make wheel forward (Gao Po) roll, thereby realize the function that wheel is climbed the building.It is overlapping that four wheels in one group of wheel also can two or two, is inverted v-shaped, has only two wheels to land, and the space can reduce.
The utility model also is applicable on the sandy beach and uses.
