Abstract
A simple speed adjusting device on a toy car comprises a screw which is connected to a car frame in a threaded mode, wherein the inner end of the screw is pressed on the outer wall of a rotating shaft in an abutting mode. The simple speed adjusting device on the toy car is simple and reasonable in structural design; as the screw is pressed on the outer wall of the rotating shaft in the abutting mode and friction for preventing the rotating shaft from rotating is produced between the screw and the rotating shaft, the function of adjusting the rotation flexibility of the rotating shaft is achieved, the movement speed of the toy car can be lowered, and the safety for children to use the toy car is improved.
Description
Technical field
The utility model relates to a kind of for the simple and easy arrangements for speed regulation on toy car.
Background technology
Current toy is of a great variety, toy car particularly, for toy car, be generally that the children that age is less is played, and current toy car is equipped with the wheel with rotating shaft, make toy car slide very flexible, because children is very slow on foot, can't control the toy car flexibly that slides, make children often fall down when using toy car, bring very large danger.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and the simple and easy arrangements for speed regulation on a kind of toy car are provided, and it is simple in structure, easy for installation, plays the rotation friction that increases toy vehicle wheels, the translational speed of the toy car that slows down.
The utility model solves the technical scheme that its technical problem adopts: the simple and easy arrangements for speed regulation on this toy car, and this device comprises a screw be threaded on vehicle frame, the top, the inner of screw is pressed in the rotating shaft outer wall.By rotary screw, make to move inside and outside it like this, and the active force between while set screw and rotating shaft, the flexibility ratio that rotating shaft is rotated controlled.
For further perfect, vehicle frame is provided with the through hole passed for screw, is fixed with the nut be connected with screw thread in through hole, and wherein screw is pressed in the rotating shaft outer wall through nut top.Screw can be fixedly mounted on vehicle frame more like this, and inside and outside adjusting of screw is more prone to, and result of use is good.
Screw the inner is provided with friction plate.The friction plate top is pressed in rotating shaft, increases the contact area between screw and rotating shaft, so not only can strengthen the deceleration effect, and the wearing and tearing of minimizing countershaft, friction plate can adopt the nut of spiral on screw, and nut can inside and outsidely be regulated, and also plays the effect of adjusting tightness.Be provided with cell body 1-2 in the installing hole 1-1 of installation rotating shaft 2 on vehicle frame 1, cell body 1-2 is positioned at the top of installing hole 1-1, and friction plate 6 is positioned at cell body 1-2.Such structural design is more reasonable.
The effect that the utility model is useful is: the utility model structural design advantages of simple; push up and be pressed in the rotating shaft outer wall by screw; produce the frictional force that stops the rotating shaft rotation between screw and rotating shaft; thereby play the effect of the flexibility ratio of regulating the rotating shaft rotation; can slow down the like this translational speed of toy car, child protection is used the safety of toy car.
The accompanying drawing explanation
Fig. 1 is that the utility model is that the structure chart of arrangements for speed regulation is installed on vehicle frame;
The enlarged diagram that Fig. 2 is A part in Fig. 1;
Fig. 3 is that the utility model is that the cutaway view of arrangements for speed regulation is installed on vehicle frame; Wherein in vehicle frame, be fixed with nut;
Fig. 4 is that the utility model is that the cutaway view of arrangements for speed regulation is installed on vehicle frame; Wherein nut the inner is equipped with friction plate.
Description of reference numerals: vehicle frame 1, installing hole 1-1, cell body 1-2, through hole 1-3, rotating shaft 2, wheel 3, screw 4, nut 5, friction plate 6.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: the simple and easy arrangements for speed regulation on this toy car, this device comprises a screw 4 be threaded on vehicle frame 1, and the top, the inner of screw 4 is pressed in rotating shaft 2 outer walls, and wheel 3 is installed in the outer end of rotating shaft 2.Vehicle frame 1 is provided with the through hole 1-3 passed for screw 4, is fixed with the nut 5 be threaded with screw 4 in through hole 1-3, and wherein screw 4 is pressed in rotating shaft 2 outer walls through nut 5 top.Screw 4 the inners are provided with friction plate 6, and friction plate 6 can be the nut that is threaded in screw 4 the inners, install so more conveniently, also increase the contact area between screw 4 and rotating shaft 2.Be provided with cell body 1-2 in the installing hole 1-1 of installation rotating shaft 2 on vehicle frame 1, cell body 1-2 is positioned at the top of installing hole 1-1, and friction plate 6 is positioned at cell body 1-2.The utility model structural design advantages of simple; be pressed in rotating shaft 2 outer walls by screw 4 tops; produce the frictional force that stops rotating shaft 2 rotations between screw 4 and rotating shaft 2; thereby play the effect of the flexibility ratio of regulating rotating shaft 2 rotations; can slow down the like this translational speed of toy car, child protection is used the safety of toy car.
Although the utility model illustrates and describes by reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and details.
