Description

The auxiliary steering mechanism of compound type carriage for children

The utility model relates to a kind of compound type carriage for children auxiliary steering mechanism.

The car body of normal children's Straddle riding type, its whole locomotive body overwhelming majority is all established the mode combination with weldering, make it constitute a kind of firm perambulator, its handlebar and mode of connection between the body of recoil are that the two ends by a hack lever contact with it, and then the sticking formation of weldering, on the pedestal leading edge pipe support of back, weld jack base earlier, install the frame that holds a writing brush or pen-write of holding up of a bending, afterwards in order to prevent that the child from extracting it, and between the jack base of holding up hold a writing brush or pen-write frame and back pedestal leading edge pipe support, give again and welding, so not only on whole manufacturing process, very waste man-hour, outside the weldering knot material, and on the packaging volume of fixed body, very show again and take up space, also cause simultaneously in transporting, bumping against easily and touches phenomenon.And normal children's car system directly controls for child oneself and turns to, therefore whenever becoming human desires instruction child study just must bend over to hold up to hold handlebar when turning to, so that just cause this adult's waist bar to ache, endure not get up painful shape after a period of time, so be the actual bodily harm when a kind of child of education that is grown up is driven on the contrary.

The purpose of this utility model provides a kind of auxiliary steering mechanism of compound type carriage for children, and this mechanism can make to control and turn to conveniently, and tool incabloc function, practical comfortable.

For achieving the above object the utility model by the following technical solutions: auxiliary steering mechanism comprises: preceding handlebar, vehicle frame, back handle hand, and it is respectively:

Preceding handlebar is provided with two and goes to upper and lower the pivot joint connecting support that splits, it articulates connecting support circular hole, put the hollow sleeve of a vehicle frame front end between circular hole and with a plug with its combination, preceding handlebar below articulates one circular hole both sides, connecting support center and has circle perforation, circle perforation for the sheathed combination of connecting rod:

Being shaped on a cushion pivot connecting seat and middle back segment position in the middle of the vehicle frame has to hold and holds the hollow base that dimple and protrudes out shape, it is connect respectively establish a cushion, a spring coil and a back handle hand;

Cushion is to be shaped in the cushion pivot connecting seat in the middle of being installed on vehicle frame, and has one can fill the air bag cushion that air inlet is used;

Back handle hand, tie up to the both sides, lower end and make the connecting strap that protrudes out, on this connecting strap that protrudes out and circle perforation arranged, make the hollow base of its hub setting in vehicle frame, think and cooperate preceding handlebar below to articulate the rounding perforation of connecting support center one circular hole both sides institute, make each sheathed connecting rod combination about it, and below protruding out connecting strap, also dig the spacing short slot that is provided with an ellipticity again, make to constitute this back handle hand rotational angle limit setting behind its hollow base one screw that is incorporated into vehicle frame and by a fly-headed bolt.

The utility model is described in further detail below in conjunction with accompanying drawing:

As Fig. 1-A ,-B and shown in Figure 2: a kind of auxiliary steering mechanism of compound type carriage for children, it is made of a preceding handlebar 1, vehicle frame 2, back handle hand 3, its front truck is provided with the two pivot joint connecting supports 11 that go to upper and lower to 1, it articulates connecting support 11 circular hole 111, the hollow sleeve 21 of ccontaining vehicle frame 2 front ends between circular hole, and with a plug 1A combination, and there is the perforation of justifying 112 both sides of preceding handlebar 1 below pivot joint connecting support 11 center holes 111, these hole confession connecting rod 6 sheathed combinations; Have to hold and hold the hollow base 23 that dimple 22 and protrudes out shape and be shaped on a cushion pivot connecting seat 24 and middle back segment position in the middle of the vehicle frame 2, it is connect respectively establish a cushion 4, a spring coil 5 and a back handle 3, think that this spring coil 5 can produce a shock-absorbing effect when running into Uneven road after touch mutually with cushion 4, and cushion 4 and have one can fill air inlet with and the air bag cushion 41 of tool animal ear moulding; Back handle hand 3 lower ends two collateral lines are made the connecting strap 31 that protrudes out, on this connecting strap that protrudes out 31 and circle perforation 311 arranged, think and cooperate preceding handlebar 1 below to articulate connecting support 11 centers one circular hole, 111 both sides institute rounding perforation 112, make about it each sheathed connecting rod 6 in conjunction with (as figure-B), and below protruding out connecting strap 31, also dig the spacing short slot 32 that is provided with an ellipticity again, make it when hollow base 23 1 screws 231 that are incorporated into vehicle frame 2, and, cause connecting rod 6 impaired to avoid excessive angular turn by the limit setting that fly-headed bolt 2A constitutes these back handle hand 3 rotational angles; Satisfy with by by after spring coils 5 are provided with under handlebar 1 before being connected with of connecting rod 6 and back handle hand 3 and the cushion 4, promptly shown in Figure 2, the child in the study when making it only will be static by back handle hand 3 drives voluntarily (as Fig. 3-A), and if auxiliary child that must the adult is when learning to drive, then by back handle hand 3 be or a left side or right steering operation (as Fig. 3-B ,-C) get final product, do not bend over and cause the injury virtually of health spinal cord just must not make thus to be grown up.

Simultaneously, when child each time takes advantage of seat in cushion 4, then gas is being subjected under the state of pushing in the air bag cushion on the cushion 4 41, and makes the air bag cushion 41 of animal ear moulding be little aliform (as shown in Figure 4), is the practical effect of holding and attract to consume use with comfortable seat.

Among Fig. 5, A is that handlebar, A2 are the recoil body for perambulator A1, and A21 is that leading edge pipe support A22 is a jack base, and A3 is for staying bar A4 for holding up the frame that holds a writing brush or pen-write.

Advantage of the present utility model: adopt this auxiliary steering mechanism, not only control and turn to convenience and tool shock-absorbing Function, practical comfortable.
