Abstract
The utility model discloses an infant wheel capable of automatically braking. The infant wheel structurally comprises a wheel body and an axle. The wheel body comprises an outer wheel body, an inner wheel body and the axle. The axle is arranged at the center of the inner wheel body, and a certain gap exists between the outer wheel body and the inner wheel body. Two semi-round brake pieces are arranged in the gap, and grooves are evenly distributed in the outer ring of the inner wheel body. Each groove is provided with a spherical flying hammer, one half of each flying hammer is embedded into each groove, and the other half of each flying hammer is positioned into a space among the brake pieces and the inner wheel body. When the infant wheel capable of automatically braking rotates too fast, automatic braking can be achieved through friction between the brake pieces and the outer wheel, and therefore an infant sitting in an infant vehicle can be prevented from being injured.
Description
Technical field
The utility model relates to the wheel of installing on a kind of perambulator, specifically a kind of can self-stopping perambulator wheel.
Background technology
When people were pushing away perambulator and go out, if do not catch perambulator during descending, accident was loosed one's grip when perhaps car being parked in down-hill position, the capital causes perambulator fast to preshoot, existing perambulator does not have dead-man's device, gently then can frighten child, and is heavy then can be with child's tumble injury.
The utility model content
The purpose of this utility model be to provide a kind of can self-stopping perambulator wheel, have brake gear on this perambulator wheel, can brake voluntarily when the perambulator speed of advance is too fast.
The technical scheme in the invention for solving the technical problem is: a kind of can self-stopping perambulator wheel, its structure comprises wheel and axle, described wheel comprises wheel and axle in car foreign steamer, the car, axle is positioned at the center of car wheel, be provided with a fixed gap between car foreign steamer and the Che Nei wheel, two semi-round brake facings are installed in the space, the outer ring of wheel is provided with the well-distributed groove in the car, be provided with the flyball of a sphere in each groove, half embeds flyball in the groove, in the space between second half is taken turns in brake facing and car.
The beneficial effects of the utility model are: this can self-stopping perambulator wheel when rotating speed is too fast, can realize self-actuating brake by the friction of brake facing and car foreign steamer, the child who avoids being sitting on the perambulator is injured.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 car foreign steamer, wheel in 2 brake facings, 3 cars, 4 flyballs, 5.
The specific embodiment
As shown in Figure 1.A kind of can self-stopping perambulator wheel, comprise wheel and axle, described wheel comprises wheel 3 and axle 5 in car foreign steamer 1, the car, axle 5 is positioned at the center of car wheel 3, is provided with a fixed gap between car foreign steamer 1 and the Che Nei wheel 3, and two semi-round brake facings 2 are installed in the space, the outer ring of wheel 3 is provided with the well-distributed groove in the car, be provided with the flyball 4 of a sphere in each groove, half embeds flyball 4 in grooves, and second half is taken turns in brake facing 2 and car in the space between 3.
This can self-stopping perambulator wheel when rotating speed is too fast, centnifugal force makes flyball 4 to external compression, compressing brake facing 3 makes brake facing 3 and 1 friction of car foreign steamer, friction force makes vehicle wheel rotational speed progressively slack-off, finally stops.
