Abstract

The utility model relates to a tricycle for children, which comprises a tricycle frame, wheels arranged under the tricycle frame, and pedals [1] used for driving the wheels to rotate, wherein, one connecting element [12] is sheathed on a steering bundle [8]; the steering handle [8] is rotatablely connected with the connecting element [12]; a C-type opening clamping element [13] is arranged at the back of the connecting element [12]. One pushing handle [9] has two operating positions, wherein, a first operating position is that the pushing handle [9] is positioned at the back of a back tricycle frame [7]; the pushing handle [9] is contained in the opening clamping element [13]; the second operating position is that the pushing handle [9] is disengaged from the opening clamping element [13] and turns down to under the frame. Because one connecting element is sheathed on the steering handle, the steering handle is rotatablely connected with the connecting element; therefore, when the connecting element is connected with the pushing handle, the rotation of the steering handle can be influenced; the structure for fixing the pushing handle is simple and convenient.

Description

Child's tricycle

Technical field

The utility model relates to a kind of child's tricycle.

Background technology

Present child's tricycle comprises vehicle frame, be arranged at the wheel of vehicle frame below, be used for the tread plate that drive wheels is rotated, described vehicle frame comprises front vehicle frame and back vehicle frame, described front vehicle frame is connected between the vehicle frame rotationally with the back, the below of described front vehicle frame is provided with the front fork of bifurcated, described front fork is provided with a front-wheel, the top left-right symmetric of described front vehicle frame is connected with handgrip, the top, middle part of described back vehicle frame is provided with the seat, the left and right sides of the lower rear of described back vehicle frame is provided with trailing wheel, the rear portion of described back vehicle frame is provided with the handle that turns to of setting, a handle can be used as the handle use and is positioned at the vehicle frame rear side, can be used as also that rocking bar uses and the downside that is positioned at vehicle frame, when using as handle, the rear portion how this handle is fixed in vehicle frame becomes an insoluble problem, because turn to being a rotary rod member, therefore turn to needs the rotation direction of needs control front-wheel often to rotate.

Summary of the invention

It is a kind of when handle is positioned at the rear side of vehicle frame that the purpose of this utility model is to provide, the child's tricycle that can locate handle easily.

The technical solution of the utility model is: a kind of child's tricycle, comprise vehicle frame, be arranged at the wheel of vehicle frame below, be used for the tread plate that drive wheels is rotated, described vehicle frame comprises front vehicle frame and back vehicle frame, described front vehicle frame is connected between the vehicle frame rotationally with the back, the below of described front vehicle frame is provided with the front fork of bifurcated, described front fork is provided with a front-wheel, the top left-right symmetric of described front vehicle frame is connected with handgrip, the top, middle part of described back vehicle frame is provided with the seat, the left and right sides of the lower rear of described back vehicle frame [7] is provided with trailing wheel, the rear portion of described back vehicle frame is provided with the handle that turns to of setting, an attaching parts is enclosed within and turns to last, turn to handle to be rotatably connected with attaching parts, the rear portion of attaching parts is provided with C type opening fastener; A handle has two control positioies, and first control position is the rear portion that handle is positioned at the back vehicle frame, and the opening fastener contains handle; Second control position is that handle breaks away from the opening fastener and following below of turning over to vehicle frame.

The utility model compared with prior art has following advantage:

Because an attaching parts is enclosed within and turns to last, turn to be rotatably connected, so attaching parts can not influence the rotation that turns to handle, fixedly the convenience simple in structure of handle when being connected with handle with attaching parts.
