Abstract

The utility model relates to a children's tricycle. The utility model is composed of a front decorative plate with a front wheel cover, a handle bracket, a vegetable basket positioned on the upper side of two rear wheels and which is connected with a rear wheel cover, a main bracket seat, a front wheel, a left pedal lever, a tight pedal lever, the two rear wheels and other members, which are all formed in integral forming way. Thus, the utility model can reduce processing procedures of welding, locking with screws, etc. Besides, the utility model can save the members and relatively reduce the cost, and the utility model has the effect of convenient, rapid and safe assembly.

Description

Children's tricycle

The utility model relates to a kind of child's tricycle, particularly a kind of child's tricycle of structural development.

Normal children's three-wheel vehicle (1) as shown in Figure 1, it mainly is made up of handle supporting (11), front-wheel (12), front shroud (13), left and right foot-driven lever (14) (15), front plaquette (16), main support (17), seat cushion (18), two trailing wheels (19) and food basket members such as (20), and there is following shortcoming in it:

1, each member must lock separately, therefore assembles formality and quite bothers, and relative cost also increases.

2, owing to must mutually link between each member or solid with the screw spiral shell, so member the more, the point of binding also the more, and the irony concatenator is in the majority with hard, sharp keen person at present, so increase also relative to the threat of child safety.

3, a lot of local must welding fixing (as main support (17) back and the cross bar of below and crossbeam (114) position of handle supporting (11) before), waste of manpower and time.

4, in order to simplify decoration, two poles (111) of main support (11) tail down bending extension are directly fixing with two trailing wheels (19), and there is no two wheel covers, because if will install two wheel covers, it certainly will will change the structure of main support region of interest such as (11), and increase accessory and combine and assemble man-hour relatively.

5, owing to no wheel cover, its safety reduces for toy for children, relatively loses the retaining mud effect of wheel cover.

In order to overcome the deficiency of prior art, the invention provides a kind of child's tricycle of structural development, reaching work programmes such as reducing welding and screw locking, but and the saving member cost-cutting, assembling is fast, enhances productivity relatively and safety and be difficult for the scratch user.

A kind of child's tricycle described in the utility model comprises:

One of integrally formed handle supporting, outwards bend and establish grip on the pole of both sides respectively, be provided with crossbeam in the middle of two poles, it is fixing that it and main support seat hold pivot connecting seat to be pivoted before, respectively have perforate in addition and be arranged with cushion cover respectively below its both sides pole, left and right foot-driven lever runs through this perforate;

One front plaquette, its below is provided with a front shroud;

One food basket, its both sides, top have two wheel covers;

An one left foot treadle and a right crus of diaphragm treadle;

Two trailing wheels;

One front-wheel is to be positioned at side under main support seat the place ahead, and its front-wheel both sides are coated with left foot treadle and the right crus of diaphragm treadle that runs through pole below, handle supporting both sides respectively;

Integrally formed main support seat, its top is provided with seat cushion, and its front side is provided with pivot connecting seat, this pivot connecting seat of mat can be pivoted fixing with handle supporting, afterbody then bends and is extended with two downward-sloping poles and is connected with a crossbeam in addition, it can be for locking one food basket, and the terminal both sides of two poles are pivoted respectively and are fixed with two trailing wheels;

It is characterized in that:

This handle supporting is the cushion cover of pole below, integrally formed tool both sides and the crossbeam in the middle of the pole of both sides;

This front plaquette below is integrally formed to have a front shroud;

Both sides, this dish indigo plant top are integrally formed to have the wheel cover that is positioned at the trailing wheel top;

This main support seat is one of the forming and has seat cushion and pivot connecting seat.

Description of drawings:

Fig. 1 is the three-dimensional exploded view of common product.

Fig. 2 is this practical three-dimensional exploded view.

Fig. 3 is a block diagram of the present utility model.

Describe the utility model in detail below in conjunction with accompanying drawing.

As Fig. 2, shown in Figure 3, child's tricycle of the present utility model comprises:

One of integrally formed handle supporting (3), front end is provided with a front plaquette (5), then outwards bend and be provided with grip (321) on the both sides pole (32) respectively, be provided with crossbeam (34) in the middle of two poles (32), the front end pivot connecting seat (41) of it and main support seat (4) seat is pivoted fixing, in addition, perforate is respectively arranged and be arranged with cushion cover (322) respectively its both sides pole (32), it runs through it by left and right foot-driven lever (14) (15) respectively;

One front plaquette (5), its below is provided with a front shroud (51);

One dish indigo plant (20), its both sides, top have two wheel caps (201) (202);

An one left foot treadle (14) and a right crus of diaphragm treadle (15);

Two trailing wheels (29);

One front-wheel (12) be positioned at side under main support seat (4) the place ahead, and its front-wheel (12) both sides is coated with the left foot treadle (14) and right crus of diaphragm treadle (15) that runs through handle supporting (3) both sides poles (32) below respectively;

Integrally formed main support (4), its top is provided with seat cushion (42), and its front side is provided with pivot connecting seat (41), this pivot connecting seat of mat (41) can be pivoted fixing with handle supporting (3), its afterbody then bends and is extended with downward-sloping two poles (43) and easily is connected with a crossbeam (431) in addition, it can be for locking dish indigo plant (20), and these terminal both sides of two pole (43) are pivoted respectively and fix two trailing wheels (29) in addition;

Handle supporting in the utility model (3), being one of the forming has the cushion cover (322) and both sides pole (32) intermediate transverse girder (34) of both sides pole (32) below;

This main support seat (4) is integrally formed have seat cushion (42) and pivot connecting seat (41);

This front plaquette (5), being one of the forming has a front shroud (51);

This food basket (20) is one of the forming and has the wheel cover (201) that is positioned at two trailing wheels (19) tops;

Moreover aforementioned handle supporting (3) is to be all rigidity plastics or PP impact resistant plastics or nylon plastic(s) with main support seat (4), to increase the steadiness of its structure.

But the utility model saving member, cost-cutting, and reach the safe effect that has concurrently again fast easy to assembly.
