Summary of the invention

The technical problems to be solved in the utility model provides a kind of folding child's tricycle that can reduce to take up an area the space when store status.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of folding child's tricycle, comprise main body of vehicle frame and V-shaped rest, the two ends of this V-shaped rest all are equiped with trailing wheel, described main body of vehicle frame is provided with permanent seat and drive-connecting shaft, the middle part of described V-shaped rest is provided with hinged seat, and drive-connecting shaft passes permanent seat and hinged seat.

Wherein, described drive-connecting shaft is set with the stop inner sleeve of captiveing joint with hinged seat and the stop overcoat of captiveing joint with permanent seat, the stop inner sleeve is positioned at the stop overcoat, the outer wall of stop inner sleeve offers storage tank, be equiped with button and spring in this storage tank, the two ends of this spring respectively with the bottom of storage tank and the inner butt of button; The sidewall of described stop overcoat offers stop hole, and when main body of vehicle frame and V-shaped rest launched, stop hole was passed in the outer end of button.

Wherein, the middle part of described V-shaped rest is provided with back-up block, the bottom butt of this back-up block and described main body of vehicle frame.

Wherein, the upper surface of described back-up block offers groove, and the bottom of described main body of vehicle frame is embedded at this groove.

Wherein, the inboard of described V-shaped rest is provided with storage tank.

Wherein, described storage tank is triangular in shape, the inboard butt of the two side of storage tank and described V-shaped rest.

The beneficial effects of the utility model are: the utility model provides a kind of folding child's tricycle, comprise main body of vehicle frame and V-shaped rest, the two ends of this V-shaped rest all are equiped with trailing wheel, described main body of vehicle frame is provided with permanent seat and drive-connecting shaft, the middle part of described V-shaped rest is provided with hinged seat, and drive-connecting shaft passes permanent seat and hinged seat.The V-shaped rest of the utility model folding child's tricycle can rotate around drive-connecting shaft, and in use, the rear that described V-shaped rest is turned to drive-connecting shaft can normally be used; When needs are stored child's tricycle or transport, described V-shaped rest is turned to the place ahead of drive-connecting shaft, front-wheel and the trailing wheel of child's tricycle are folded together, and have greatly reduced taking up room of child's tricycle, and convenient storage and transportation are practical.

The specific embodiment

For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that embodiment is mentioned not is to restriction of the present utility model.

As shown in Figures 1 to 4, a kind of folding child's tricycle, comprise main body of vehicle frame 1 and V-shaped rest 2, the two ends of this V-shaped rest 2 all are equiped with trailing wheel 3, described main body of vehicle frame 1 is provided with permanent seat 4 and drive-connecting shaft 5, the middle part of described V-shaped rest 2 is provided with hinged seat 6, and drive-connecting shaft 5 passes permanent seat 4 and hinged seat 6.

The V-shaped rest 2 of the utility model folding child's tricycle can rotate around drive-connecting shaft 5, and in use, the rear that described V-shaped rest 2 is turned to drive-connecting shaft 5 can normally be used; When needs are stored child's tricycle or transport, described V-shaped rest 2 is turned to the place ahead of drive-connecting shaft 5, the front-wheel of child's tricycle and trailing wheel 3 are folded together, and have greatly reduced taking up room of child's tricycle, convenient storage and transportation, practical.

In the present embodiment, described drive-connecting shaft 5 is set with the stop inner sleeve 7 of captiveing joint with hinged seat 6 and the stop overcoat 8 of captiveing joint with permanent seat 4, stop inner sleeve 7 is positioned at stop overcoat 8, the outer wall of stop inner sleeve 7 offers storage tank 9, be equiped with button 10 and spring 11 in this storage tank 9, the two ends of this spring 11 respectively with the bottom of storage tank 9 and the inner butt of button 10; The sidewall of described stop overcoat 8 offers stop hole 12, and when main body of vehicle frame 1 launched with V-shaped rest 2, stop hole 12 was passed in the outer end of button 10.

In the use procedure of child's tricycle, stop hole 12 is passed in the outer end of button 10, rotates the configuration state when making child's tricycle remain on the use state around described drive-connecting shaft 5 voluntarily to prevent V-shaped rest 2; When needs with child's tricycle is folding when storing or transporting, press described button 10, make after button 10 is retracted in the storage tank 9 fully, can easily V-shaped rest 2 be turned to the place ahead of drive-connecting shaft 5 around drive-connecting shaft 5; When needing to launch child's tricycle, V-shaped rest 2 is got final product around the rear of drive-connecting shaft 5 backward rotation to drive-connecting shaft 5, button 10 ejects under the effect of spring 11 and passes stop hole 12, and is simple in structure, easy to use.

The middle part of the described V-shaped rest 2 of the present embodiment is provided with back-up block 13, the bottom butt of this back-up block 13 and described main body of vehicle frame 1, when launching child's tricycle, being provided for of back-up block 13 prevents that V-shaped rest 2 from continuing upwards to rotate, keep between described main body of vehicle frame 1 and the ground certain altitude being arranged, guarantee the normal use of child's tricycle.

Concrete, the upper surface of described back-up block 13 offers groove 14, and the bottom of described main body of vehicle frame 1 is embedded at this groove 14, to prevent that main body of vehicle frame 1 is with respect to back-up block 13 double swerves, improve the stabilized structure of child's tricycle, prolonged the service life of child's tricycle.

The inboard of the described V-shaped rest 2 of the present embodiment is provided with storage tank 15, concrete, described storage tank 15 is triangular in shape, the inboard butt of the two side of storage tank 15 and described V-shaped rest 2, the setting of storage tank 15 can additionally not increase taking up room of child's tricycle, be convenient to deposit other toy or carry-on object etc., practicality is stronger.
