Abstract

The utility model provides a rear control turning double-seat tricycle, which includes a vehicle frame 7, a front fork 4, a front wheel 1, a front seat 6, two rear wheels 13, a rear wheel shaft 14, a rear seat 8, a rear seat backrest 9, a turning handle 10, a turning link rod 12, a rear shaft supporting tube 15, a connecting tube 20, and a hasp 11. The rear shaft supporting tube 15 is fixed on the middle part of the rear wheel shaft 14. A short tube on the front part of the connecting tube is inserted and fixed in the rear shaft supporting tube 15. The lower end of turning handle 10 passes through a sleeve ring 19 on the connecting tube, and a convex block 16 is fixed on the lower end face of the turning handle. The middle part of the turning handle passes through the hasp 11 on the rear seat backrest. The front end of the turning link rod 12 is inserted in a hole 17 arranged on one side of a transverse board 2 on the front fork, and the rear end of the turning link rod is inserted in a hole 18 on the convex block 16 on the lower end of the turning handle 10. When in use, the adult stands behind the tricycle to turn the turning handle by hand, and the direction of the front wheel can deflect under the driving of the turning link rod, and then the tricycle can change the direction of the progress according to requirements.

Description

The back control turns to the two-seater toy tricycle

(1) technical field:

The utility model relates to a kind of structure of perambulator, and the control of a kind of back turns to the two-seater toy tricycle.

(2) background technology:

Perambulator is children's play and exercise instrument by bike.There is a kind of perambulator that two seats are arranged, one in front and one in back.When being sitting in front stall, the step on the moving front-wheel that can tramp with one's feet moves ahead car, and children can practise by bike with it.Toe board is arranged below the back seat.The handle that a big human hand barrow of confession can also be arranged on the back backrest.This car, when big human hand propelled, control car working direction is not too convenient.

(3) summary of the invention:

The purpose of this utility model is the two-seater toy tricycle that proposes to be easy to control when a kind of adult promotes the car working direction, and the control of a kind of back turns to the two-seater toy tricycle.

The control of this back turns to the two-seater toy tricycle, comprise vehicle frame, front fork, front-wheel, preceding seat, two trailing wheels, hind axle, back seat and recoil backrest, there are two transverse slats at the middle part of front fork, the front end of vehicle frame inserts between two transverse slats of front fork, by pin the vehicle frame front end is connected with transverse slat, it also comprises and turns to handle, steering connecting rod, the rear axle arm, connection pipe and hasp, the rear axle arm is fixed on the middle part of hind axle, the front portion of connection pipe is a short tube, there is a lasso at the rear portion, the short tube of connection pipe front portion inserts in the rear axle arm, and fix with it, turn to the lower end of handle to pass lasso on the connection pipe, turn on the lower surface of handle and fixing the projection that protrudes to a side, the middle part of hasp circularizes, its two ends and recoil backrest fix, turn to the middle part of handle to pass from the annular of hasp, the front end of steering connecting rod inserts in the hole of transverse slat one side on the front fork, and insert in the hole on the projection that turns to the handle lower end rear end of steering connecting rod.

When the control of this back turns to the two-seater toy tricycle to use, after the adult stands in car, turn to the handle that adds on handle or the recoil backrest, can promote car forward with hand propelled.Turn to handle with hand, because the drive of steering connecting rod can make the direction deflection of front-wheel, car just can change working direction on request.

Accompanying drawing 1 is the integral structure figure that the control of this back turns to the two-seater toy tricycle;

Accompanying drawing 2 is schematic diagrams that front fork connects to ground;

Accompanying drawing 3 is the catenation principle figure that turn to handle and steering connecting rod, hind axle, reach the recoil backrest;

Accompanying drawing 4 is exploded of Fig. 3;

Accompanying drawing 5 is telescopic constructionals drawing that turn to handle.

(5) specific embodiment:

As depicted in figs. 1 and 2, the control of this back turns to the two-seater toy tricycle, comprise vehicle frame 7, front fork 4, front-wheel 1, preceding seat 6, two trailing wheels 13, hind axle 14, back seat 8 and recoil backrests 9, there are two

transverse slats

2,3 at the middle part of front fork, the front end of vehicle frame 7 inserts between two transverse slats of front fork, by pin 5 the vehicle frame front end is connected with transverse slat.As Fig. 1, Fig. 3 and shown in Figure 4, the control of this back turns to the two-seater toy tricycle also to comprise and turns to handle 10, steering connecting rod 12, rear axle arm 15, connection pipe 20 and hasp 11.Rear axle arm 15 is fixed on the middle part of hind axle 14.The front portion of connection pipe 20 is a short tube, and there is a lasso 19 at the rear portion, and the short tube of connection pipe front portion inserts in the rear axle arm 15, and fixes with it.Turn to the lower end of handle 10 to pass lasso 19 on the connection pipe, turn on the lower surface of handle and fixing the projection 16 that protrudes to a side.The middle part of hasp 11 circularizes, and its two ends and recoil backrest 9 fix, and turns to the middle part of handle to pass from the annular of hasp 11.The front end of steering connecting rod 12 inserts in the hole 17 of transverse slat 2 one sides on the front fork (referring to Fig. 2), and insert in the hole 18 on the projection 16 that turns to handle 10 lower ends the rear end of steering connecting rod 12.Pin 21 among Fig. 4 is used for fixing connection pipe 20 and rear axle arm.Pin 22 is to be used for making the lower end and the projection 16 that turn to handle 10 to fix.This back is controlled can also a handle that supplies adult's go-cart to use on the recoil backrest that turns to the two-seater toy tricycle, do not draw among the figure.

As shown in Figure 5, this back control turns to the handle that turns to of two-seater toy tricycle can also make telescoping, and bar 24 and outer bar 25 two parts in its straight-bar portion comprises, interior bar are outside the upper end insertion of outer bar the bar, the upper end of interior bar links to each other with handle 23, and the lower end of outer bar and projection 16 fix.The cross section of interior bar is square, and the cross section, top of outer bar is square, and the cross section of the bottom of outer bar is circular.This structure turns to handle time spent not, in the outer bar of bar retraction, is beneficial to the implementation of car in can making, the volume in the time of also can reducing to dismantle the back packing.
