Abstract
The utility model relates to a hand tricycle for children, comprising a front wheel, a back wheel, a horse head and a cranking bar arranged on one end of the horse head. The horse head can swing around a pin shaft fixed on a horse body. The utility model is characterized in that double connection ratchet wheels are arranged on the wheel shaft of rear wheels; a chain on the double connection ratchet can respectively be connected with both ends of a straight pull-bar through connection bars; the straight pull-bar can be connected with the lower end of the horse head through a transverse pull-bar. The utility model has high mechanical efficiency and stable tricycle speed; the utility model has the interesting when rid; the children's whole bodies can be sufficiently exercised.
Description
The utility model relates to a kind of Hand tricycle for child.
The Chinese patent application (GG8211356) that name is called " multipotency hand-car " discloses a kind of hand-propelled tricycle, and it is made up of crank, the parts such as ratchet, chain and pull back spring that are contained on the trailing wheel.The pulling crank drives chain, ratchet can make trailing wheel rotate, and pushes back crank, and chain resets under the pull back spring effect, and ratchet skids, and does not influence trailing wheel and advances.Its weak point is, just car being advanced when having only the pulling crank has contribution, is an idle travel and push back crank, and mechanical efficiency is lower and the speed of a motor vehicle is unstable.
The purpose of this utility model is will overcome the deficiency of above-mentioned prior art and the Hand tricycle for child that a kind of mechanical efficiency is higher, the speed of a motor vehicle is stable is provided.
The purpose of this utility model can take following measure to reach:
A kind of Hand tricycle for child, comprise front-wheel, trailing wheel, head of the horse and the crank that is contained in head of the horse one end, head of the horse can be around the bearing pin swing that is fixed on the length, it is characterized in that on rear axle, being equipped with left ratchet and right ratchet, chain on it is connected with the two ends of drag link by connecting rod respectively, and drag link is connected with the lower end of head of the horse by intermediate rod.
The purpose of this utility model can also reach by following measure:
Escapement and step are housed on the described front-wheel.
Because the utility model has been taked above-mentioned technical measures, making it to contrast prior art has following advantage:
1,, makes to push away or spur that crank all can drive chain, ratchet turns a wheel that mechanical efficiency is higher and the speed of a motor vehicle stable owing to adopted the doubly-linked escapement.
2, front-wheel is equipped with step and escapement, available foot-operated driving front-wheel.
3, its crank is the head of the horse image, shakes crank perambulator is advanced the spitting image of the action of riding, and both can increase interest, makes children's health obtain taking exercise again.
The drawing explanation of accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below with reference to embodiment: with reference to accompanying drawing, the utility model comprises front-wheel (5), trailing wheel (16), head of the horse (1) and the device crank (2) at head of the horse (1) one end, and head of the horse (1) can be around bearing pin (17) swing that is fixed on the length (3).Left ratchet (13) and right ratchet (11) are housed on trailing wheel (16) wheel shaft, drive by left chain (12) and right chain (10) respectively.The lower end of head of the horse (1) is connected with drag link (9) by intermediate rod (8).The two ends of drag link (9) are connected with four connecting rods (14) respectively, and the other end of connecting rod (14) is connected with the two ends of left and right chain (12), (10) respectively.Should stagger mutually with being connected of drag link (9) in left and right chain (12), (10), be that the upper end of left chain (12) and the lower end of right chain (10) are connected by the lower end of connecting rod with drag link (9), and the upper end of the lower end of left chain and right chain is connected by the upper end of connecting rod with drag link (9).Like this, when pulling head of the horse crank (2), the lower end of head of the horse (1) spurs direct bar (9) by intermediate rod (8), and drag link (9) is by connecting rod (14) pulling chain.At this moment, right chain (10) drives right ratchet (11) rotation advances trailing wheel (16), and left chain (12) skids on left ratchet (13); When promoting head of the horse crank (2), the lower end of head of the horse (1) promotes drag link (9) by intermediate rod (8), and drag link (9) is by connecting rod (14) pulling chain.At this moment, left chain (12) drives left ratchet (13) rotation advances trailing wheel (16), and right chain (10) skids on right ratchet (11).Front-wheel mechanism is made up of front-wheel (5), front fork (4), step (6) and escapement (7).When using back-wheel drive, can grasp the direction that car advances by step (6) control front-wheel (5).Also available pedal drives front-wheel advances car.
Claims (2)
1, a kind of Hand tricycle for child, comprise front-wheel (5), trailing wheel (16), head of the horse (1) and the crank (2) that is contained in head of the horse (1) one end, head of the horse (1) can be around bearing pin (17) swing that is fixed on the length (3), it is characterized in that on trailing wheel (16) wheel shaft, being equipped with left ratchet (13) and right ratchet (11), chain on it (12), (10) are connected with the two ends of drag link (9) by connecting rod (14) respectively, and drag link (9) is connected with the lower end of head of the horse (1) by intermediate rod (8).
2, Hand tricycle for child according to claim 1 is characterized in that being equipped with on the described front-wheel (5) escapement (7) and step (6).
