Description

Folding pushchair

Technical field

The utility model relates to a kind of hand barrow, particularly relates to a kind of folding pushchair.

Background technology

Existing common hand barrow, its sweep, castor have not only increased the weight of car body itself all based on ferrous material, make go-cart very heavy under steam, and can produce big noise in the conveying objects process.

The utility model content

Technical problem to be solved in the utility model is to solve hand barrow car body problem heavy and the big noise of meeting generation in the conveying objects process.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of folding pushchair, comprise sweep, at least three castors and handrail, described castor is installed in respectively on the bottom surface of sweep, the material of described base plate is a synthetic plastics, described castor is quiet castor, the rear portion of plate upper surface is provided with two handrail mount pads, this handrail mount pad comprises two vertical with plate upper surface respectively risers, described handrail takes the shape of the letter U, and two free end is inserted into respectively between two risers of described handrail mount pad and is hinged with riser respectively.

On the basis of such scheme, also comprise the folding operation device, described folding operation device comprises front limit bearing pin, folding operation bar and torsion spring, relatively be provided with vertical Long Circle through hole on the described riser respectively, described front limit bearing pin is fixedly mounted between two risers of handrail mount pad, two free ends of folding operation bar are installed on respectively between front limit bearing pin and the folding operation bar and are hinged with the riser of handrail mount pad respectively, and the two ends of torsion spring are separately fixed on front limit bearing pin and the folding operation bar.

Be fixed with the plurality of rubber slipmat on the described sweep upper surface.

The quantity of described rubber antiskid pad is four, and it highly is 1～5mm.

The utility model, base plate adopts synthetic plastics, and castor adopts quiet castor, handrail is collapsible to be placed on the sweep, car load is from heavy and light, moves noiselessly, brisk, is widely used in material handling industries such as plant area, office building, library, hotel, catering trade, logistics transportation.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the scheme drawing of the utility model after folding;

Fig. 3 is a folding operation apparatus structure scheme drawing;

Fig. 4 is a folding operation device diagram of work.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As Fig. 1, shown in Figure 2, the utility model comprises sweep 7, four castors 6, handrail 1 and folding operation device, base plate 7 is made by synthetic plastics, it is red that color can be respectively, yellow, green, blue, ash or other colors, be fixed with four rubber antiskid pads 4 on the upper surface of base plate 7, four rubber antiskid pads 4 are arranged on four angles of rectangle, highly be 1～5mm, be used for article anti-skidding on sweep, improve the safety of transportation, castor 6 is installed in respectively on the bottom surface of sweep 7, wherein rear truckle can be done 360 degree rotations along axis, be used for the turning of hand barrow, handrail 1 takes the shape of the letter U and the middle part is provided with two free ends 11 that handrail connecting panel 2 connects U-shaped, and handrail 1 is positioned at the part of handrail connecting panel more than 2 to the bending of car body rear, and handrail 1 adopts the SPCC gapless stainless steel tube to make, wall thickness 1.8～2.0mm, three platings are adopted on the surface, three throw technology chromium plating.

In conjunction with Fig. 3, Fig. 4, the folding operation device comprises front limit bearing pin 9, folding operation bar 5 and torsion spring 10, the rear portion of base plate 7 upper surfaces is provided with two handrail mount pads 3, this handrail mount pad 3 comprises two vertical with base plate 7 upper surfaces respectively risers 8, relatively be provided with vertical Long Circle through hole on the riser 8 respectively, front limit bearing pin 9 is fixedly mounted on respectively between two risers 8 of handrail mount pad, the two ends of folding operation bar 5 are installed on respectively in vertical Long Circle through hole on two handrail mount pad risers, and on the relative riser medial surface of two handrail mount pads 3, realize axial limiting by two back-up rings 12 retaining, two free ends 11 of handrail 1 are installed on respectively between front limit bearing pin 9 and the folding operation bar 5 and are hinged with riser 8 respectively, torsion spring 10 is separately positioned on front limit bearing pin 9 and the folding operation bar 5, is used for folding operation bar 5 and resets.

As shown in Figure 3, Figure 4, when handrail 1 needed to fold, the folded control lever 5 of backfin downwards made it be moved downward to the bottom along the Long Circle through hole, at this moment, folding operation bar 5 is positioned at below the end of free end 11 of handrail 1, it can be folded on the upper surface of sweep 7 so promote handrail 1 forward.When needs lift handrail 1, the folded control lever 5 of backfin downwards is to the Long Circle via bottoms, be pulled upwardly handrail 1, when handrail 1 is in vertical position, unclamp folding operation bar 5, under the effect of torsion spring 10, folding operation bar 5 moves up along the Long Circle through hole and is reset to the top, so folding operation bar 5 and front limit bearing pin 9 block the free end 11 of handrail 1.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
