Abstract

The utility model relates to a high frame handcart which can be folded, in order to be cooperated with workings of decorating workers when the telescopic walking stilt device is used (china patent 87201860). The fold-typed high frame comprises a plurality of groups of linkages which can be folded, and every group of the linkage forms a platform after being unfolded and is racked on the next platform. All of the linkages are loaded by a platform trailer.

Description

The overhead go-cart of folding type

The utility model relates to the overhead go-cart of a kind of folding type, is suitable for work uses such as interior decoration, the series application of its exercise question " telescopic walking stilt device " (Chinese patent: No. 87201860).

When the workman uses " telescopic walking stilt device ", be sought after one and can follow the platform that the workman walks together and adapts to the work alternation, be used for place tool and material etc.In the time of necessary, the rest that can also be seated on platform is to increase work efficiency.

The purpose of this utility model provides a kind of overhead go-cart of folding type that is used with " telescopic walking stilt device ".

A kind of foldable car comprises flat truck and foldable leverage, organizes leverage more and forms the multilayer support, every group of bar by mutual cross-articulation constitutes, a bar wherein is by two hinged formation of bar, and its end is fixed with latch, and other rod end is hinged on the flat board or platform of car.

Task of the present utility model is to finish with following method:

The folding platform that hinged array is made up of leverage on the flat bogie.Be placed on behind each platform folding on the following flat-bed end face, it is fixed and is realized by the hinge and the spring tongue of a pair of pin.During use, draw back spring tongue, promptly become platform after the leverage of folding draws back, and be fixed on the following flat-bed end face by another spring tongue.Folding leverage on the deck roof can draw back on the frame platform below by same program again.Because this type of overhead go-cart generally is no more than 2.5 meters, three to four folding platforms can achieve the goal, and leverage adopts thin-wall steel tube to make, folding and draw back and do not have too big difficulty.Drawing back flat-bed group number is advisable with the height that is fit to work.Can all draw back, can also only draw back one, two group.And can when operating altitude changes, Duola open or folding one group platform, to adapt to new operating altitude.Overhead go-cart is equipped with to brake and is pulled, as long as wheel is checked, and overhead can the use as fixed support, and can be sitting in top rest or mounting or dismounting telescopic walking stilt device.After using, can be with each platform folding one by one, last folding is placed on the flat truck.Volume is little, conveniently moving.

The workman buttresses the go-cart walking when working with " telescopic walking stilt device ", can increase the sense of security, helps increasing work efficiency.

Below, the utility model will be further described in conjunction with the accompanying drawings:

Fig. 1 is the scheme drawing of the utility model embodiment;

Fig. 2 is a first order folding scheme drawing;

Fig. 3 is the scheme drawing that lies in behind the first order folding on the end face of the second stage;

Fig. 4 is the scheme drawing that is placed on behind whole platform foldings on the flat truck.

Fig. 5 is the section-drawing of the spring tongue of the utility model employing.

With reference to articulated bracket 2 is housed on Fig. 1 flat truck 6, bar 3 and bar 4 hinged backs constitute crossbar with bar 2.Hinged below the other end of bar 4 and bar 2 and the platform 1.The other end of bar 3 is fixed on the dolly by spring tongue 5, and this moment, the sponson 10 of bar 4 other ends can not clockwise rotate bar 4, therefore supported platform 1 with latch 5.And parallel with 4 with bar 2,3 respectively bar 12,13 and bar 14 are housed above the platform 1 equally, its structure one constitutes another grade platform as described above.Like this, then form one overheadly, on overhead, be provided with bicycle type brake steel cable, as long as the handle that control is braked just can be checked wheel by three platforms with spline structure.The other end of wheel is provided with dolly handle 7.To shake hands tiltedly to be placed on the first order platform, can use as ladder.

Flat-bed expansion and folding are referring to Fig. 2, Fig. 3 and Fig. 4.

See Fig. 2 earlier, open spring tongue 25, the free end of bar 23 can be drawn close to the following hinge of bar 22.At this moment, because the power of drawing close makes bar 24 rotate to anticlockwise direction, drive platform 21 and also rotate counter clockwise, till whole bars and platform (perpendicular to the next stage platform) all parallel to each other.Whole bars and platform clockwise direction are forwarded to parallel with the next stage platform, in this moment spring tongue 25 automatic insertion rods 22 cooresponding holes (Fig. 3), the overhead one-level that has been folding.Repeat above-mentioned action, up to platform foldings at different levels to flat truck.Finished the folding process of overhead go-cart.Number in the figure 25 ', 15 ', 5 ' be used for behind folding, fixing each grade leverage for spring tongue.This process is carried out conversely, be about to overheadly begin to draw back, till whole platforms draw back (Fig. 1) by platform to leave office most.Showed the situation behind whole foldings among Fig. 4, can find out, go-cart of the present utility model, structure is very compact, is convenient to work, and it can also use as common scaffold.

The spring tongue that adopts in the utility model has been shown among Fig. 5, and 5 among Fig. 1 and 5 ' all adopts such latch, and wherein label 140 is a handle, 130 is preparation hole, and 100 is spring housing, and 110 is compression spring, 120 is the spring upper shield, and 90 is latch, and 150 is the support of entire mechanism.From figure, can know and find out, be pulled outwardly handle, overcome spring force and just can pull out latch 90, thereby carry out desired folding or expansion with hand.
