Abstract

The utility model discloses a multipurpose rocking cart, comprising a body, a transmission mechanism, a guide pulley, a pull ring, a pull stake, etc. The utility model can be used separately as a hand-operated tricycle, and a plurality of rocking carts can be connected end to end into a train used in group activities. The multipurpose rocking cart is not only suitable for families, but also suitable for kindergartens and various entertainment places.

Description

Multipurpose rocking cart

The utility model belongs to the recreation apparatus.

Number of patent application is 87207378 utility model described " body-building Recreation train ", and its every joint compartment can not singlely use, and this gives the use of this train, promotes being subjected to certain restriction.

For this reason, the utility model provide a kind of both can be as " body-building Recreation train " one by one the compartment link up use, the apparatus as collective's recreation also can use as hand-propelled tricycle in single compartment.

Structure below in conjunction with description of drawings multipotency hand-car described in the utility model, be provided with seat cushion 1 in the back upper place of central sill 8, its below connects two wheels 3 by wheel shaft 2, be provided with rotating mechanism ratchet 4 in the centre of wheel shaft 2, dish has chain 5 on ratchet 4, one end of chain 5 is fixedly connected on the spring bracket 11 that is positioned at central sill 8 belows after connecting a spring 6 again, chain 5 twined its another terminations of ratchet 4 back steel wire 12 of extending and linked to each other with T-shaped crank 9, T-shaped crank 9 is sold on central sill 8 by pin 10, T-shaped crank 9 can freely rotate by pin 10, the front end of central sill 8 is provided with tow ring 7, be provided with in the rear end of central sill 8 and pull stake 14, on seat cushion 1, choose a place to give a banquet and fill up railing 13, it is characterized in that on the central sill 8 between tow ring 7 and the pin 10, opening a circular hole 16, under it, be provided with bearing 18, it is fixed on the below of central sill 8 by meeting stile 17, the car of guide wheel 21 is pitched 23 tops and is connected a guide wheel shaft 15, guide wheel shaft 15 passes the centre hole of bearing 18 and circular hole 16 and can freely rotate, on the guide wheel shaft 15, a lateral pin 22 is established in the left and right sides in the top of bearing 18, on guide wheel shaft 15, establish a flange 19 in the below of bearing 18, each side the establishing and turn to treadle 20 of the guide wheel shaft 15 below flange 19.

When the multipotency hand-car uses separately, central sill 8 is by meeting stile 17, bearing 18 is bearing on the flange 19, the cyclist is sitting on the seat cushion 1, both feet rest and turn on the treadle 20, the rotation of controlling guide wheel 21 with stretching about both feet comes the sense of motion of maneuver vehicle, the cyclist is with the hands holding T-shaped crank 9, direction is pulled to the front, and chain 5 is forwards moved, and drives ratchet 4, wheel 3 rotates forward, whole vehicle just travels forward, and the spring 6 that links to each other with chain 5 simultaneously is elongated, after both hands loosen, spring 6 shortens, chain 5 moves backward owing to there is ratchet 4 that wheel can not rotated backward, thus a pull and a place of cyclist's both hands repeat shake T-shaped crank 9, vehicle will constantly march forward.

If it is some multipotency hand-cars are end to end, the tow ring 7 that is about to a back car is inserted in pulling in the stake 14 of last car, and joining so successively just can be linked to be a train easily, and guide wheel 15 can land or not land this moment, if guide wheel 15 does not land, then because of there being lateral pin 23 to hang on the bearing 18.So just the strength that can bring into play children collective is done collective activity, and the variety of increase activity improves children's interest.

Also can on plane on the bearing 18, open a groove 24 that is just passing through the center of circle as shown in Figure 4, groove 24 has been arranged, when some multipotency hand-cars join end to end into a train, central sill 8 is by tow ring 7 and pull hitching and setting up of stake 14, this moment the lateral pin 23 on the guide wheel shaft 15 just fall into groove 24 guide wheels 21 just can not left-right rotation, cyclist's biped is stepped on and is being turned on the treadle 20, can make double arm rocking stronger.

The advantage of multipotency hand-car described in the utility model is: can make hand-propelled tricycle separately and use, each family can buy one separately, children that also can some families altogether, several the end to end trains that are linked to be of multipotency hand-car, do collective activity, can also on tow ring, fasten rope, the haul small article, this moment the multipotency hand-car guide wheel 21, the position that will change 180 ° very naturally with state shown in Figure 1 travels forward along drawing direction with swinging.
