Abstract

An improved structure of a framework under handlebars of a baby carriage comprises a handlebar framework, a back wheel frame and a folding device, wherein, the handlebar bracket of the handlebar framework and the back wheel bracket of the back wheel frame form a reverse Y-shaped frame structure, therefore, the space of the seat of the baby carriage is increased; moreover, when the baby carriage is pushed under the action of force, the back wheel bracket can respectively lead the force applied to the handlebar bracket, therefore, the integral structure is difficult to distort and transmute.

Description

Stroller handle below skeleton structure-improved

Technical field

The utility model is relevant for a kind of stroller configuration, especially stroller handle below skeleton structure-improved.

Background technology

The perambulator rear wheel top skeleton of commonly using all is the skeleton structure of groined type, the groined type skeleton, and easy torsional deflection when bearing weight, the skeleton volume can't dwindle when folding.

Because above-mentioned disappearance drawback, the utility model people thinks that it has necessity anxious to be corrected, then be engaged in the many years of experience that Related product manufactures and designs with it, and always adhere to the well-designed theory that has, at above bad place study and composition in addition, through after constantly making great efforts, be to release stroller handle of the present utility model below skeleton structure-improved eventually, it promotes the effect of product with corrigendum good quality production structure.

Summary of the invention

The utility model purpose is, provides a kind of stroller handle below skeleton structure-improved, to overcome the defective of above-mentioned conventional confguration, make the perambulator integral structure more firm, increase the space of pedestal, integral structure is greatly simplified, and is folding the also littler minimizing cost of transportation of upper volume.

According to above-mentioned purpose, a kind of stroller handle below skeleton structure-improved comprises that handrail skeleton and rear wheel skeleton and folding mechanism constitute; It is characterized in that:

The handrail skeleton is made up of handrail and armrest support, and handrail lower end and armrest support tabling are fixed, and armrest support lower end and folding mechanism are chimeric mutually fixing;

The rear wheel skeleton is made up of two rear wheel supports and wheel cross bar, and rear wheel support is arranged on both sides, folding mechanism lower end, becomes the shape of the font of falling Y with armrest support;

Folding mechanism for fixing and the device that folds armrest support and rear wheel support, is arranged in the middle of armrest support and the rear wheel support, and the both sides, upper end are provided with two projection shape buttons, and button inside is provided with spring, and button projection position props up expansion link.

Wherein, the both sides button of folding mechanism inwardly press pressing spring simultaneously, and expansion link is foreshortened in the armrest support, armrest support can be slided up and down, and decontrols expansion link and spring gets final product involution when button, makes armrest support locate slip arbitrarily.

The utility model beneficial effect: by said structure, the utility model can reach really and make the perambulator integral structure more firm, increases the space of pedestal, and integral structure is greatly simplified, at the beneficial functional that folds the also littler minimizing cost of transportation of upper volume.

The specific embodiment

Stroller handle of the present utility model below skeleton structure-improved, it comprises that handrail skeleton 1 and rear wheel skeleton 2 and folding mechanism 3 constitute [seeing also Fig. 1]; Wherein:

Handrail skeleton 1 is made up of handrail 11 and armrest support 12, and handrail 11 lower ends can be fixed with armrest support 12 tablings, and armrest support 12 lower ends and folding mechanism 3 are chimeric mutually fixing;

Rear wheel skeleton 2 is made up of two rear wheel supports 21 and wheel cross bar 22, and rear wheel support 21 is arranged on both sides, folding mechanism 3 lower end, with the shape of 12 one-tenth fonts of falling Y of armrest support, is provided with rear wheel cross bar 22 in rear wheel support 21 lower ends;

Folding mechanism 3 (seeing also Fig. 4 or Fig. 5), for fixing and the device that folds armrest support 12 and rear wheel support 21, it is middle with rear wheel support 21 to be arranged in armrest support 12, its outer rim is provided with the handle 31 of locking armrest support 12, the both sides, upper end are provided with two projection shape buttons 32, and button 32 inside are provided with spring 33, and button projection position props up expansion link 34, reach a kind of positioning action with the flexible of expansion link 34 by spring 33, but and 31 lockings of mat handle reach the second road fixation.

Use when implementing stroller handle below skeleton structure-improved, [seeing also Fig. 1] is when using perambulator, the armrest support 11 of its handrail skeleton 1 and the rear wheel support 21 of rear wheel frame 2 are the frame structure of the font of falling Y, allow the space of perambulator pedestal increase, and when the application of force promotes, rear wheel support 21 can be with the strength that forces on the armrest support 11, can separately guide and make integral structure be difficult for torsional deflection, its rear wheel support 21 and wheel cross bar 22 join merge triangular in shape, can make perambulator more firm, [seeing also Fig. 2 figure and Fig. 4] inwardly presses pressing spring 33 simultaneously with the button 32 of folding mechanism 3 both sides, expansion link 34 is foreshortened in the armrest support 12, armrest support 11 can be slided up and down, (seeing also Fig. 5) decontrols expansion links 34 and spring 33 gets final product involution when button 32, do not slided arbitrarily in armrest support 11 location, and can press down by handle 31 and reach locking location, second road, it is minimum only to need pressing button 32 that armrest support 12 is slided down to when folding, and reaches a kind of effect enhancement effect that reduces volume and be convenient to folding.

Its characteristics are, armrest support 11 and vehicle wheel frame 2 are the frame structure of the font of falling Y, can make the perambulator integral structure more firm, and the space of pedestal greatly increases, and integral structure is greatly simplified, and is folding the also littler minimizing cost of transportation of upper volume.

Only the above person only is the utility model one preferred embodiment, when can not with qualification scope of the present utility model.Promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1, skeleton structure-improved below a kind of stroller handle comprises that handrail skeleton and rear wheel skeleton and folding mechanism constitute; It is characterized in that:

2, stroller handle below skeleton structure-improved according to claim 1, it is characterized in that, the both sides button of folding mechanism is inwardly pressed pressing spring simultaneously, expansion link is foreshortened in the armrest support, armrest support can be slided up and down, decontrol expansion link and spring gets final product involution when button, do not slided arbitrarily in the armrest support location.
