Abstract
The utility model relates to a universal folding maintenance vehicle which mainly comprises a front and a back connecting rods, an upper and a lower shelf bodies, a positioning lock, upper and lower universal wheels, etc. The upper end of the front connecting rod is provided with a front spacing rod on a position near the upper shelf body. The upper shelf body near the position of the back connecting rod is provided with a back spacing rod. A draw rod of the upper shelf body and the back spacing rod are provided with the upper universal wheels. The lower shelf body near the lower end of the back connecting rod is provided with the positioning lock which can be opened and closed. When the universal folding maintenance vehicle is folded anticlockwise for use as a stool, the upper shelf body can be reliably and firmly in the state of an upright sitting stool through the front and the back spacing rods and the positioning lock. When the universal folding maintenance vehicle is used as a lying vehicle, an upper pad part on the upper shelf body is supported by the upper universal wheels. Thus, the utility model has the function of strengthening rigidity.
Description
The utility model relates to a kind of universal wheel car, specifically refers to a kind of universal collapsible maintenance car.
The universal collapsible maintenance car that uses mainly comprises front and rear connecting rods at present, upper and lower support body, location lock, parts such as four position-limiting ears and upper and lower universal wheel.Front and rear connecting rods is passed through hinges respectively: be connected on the upper and lower support body, pad and underlay are housed respectively on the upper and lower support body; Four position-limiting ears are contained in the upper end of front and rear connecting rods respectively, are used for the spacing of upper frame when maintenance car is folding to be used; Going up universal wheel for four is contained on the support body of upper frame.Four its position-limiting actions of position-limiting ear in this structure are reliable inadequately, firm, and the rigidity of upper frame is also good inadequately simultaneously, and promptly when human body forced in pad, the last pad on the upper frame deformed easily.
The purpose of this utility model is to design a kind of simple in structure, and is spacing firmly reliable, the universal collapsible maintenance car that rigidity is strong.
In order to solve above-mentioned topic, the utility model has adopted following technical scheme: a kind of universal collapsible maintenance car mainly comprises front rod, back link, upper frame, lower frame, location lock and part such as universal wheel up and down; Front-rear linkage is connected on the dual-side of lower frame by hinges respectively, pad and underlay are housed respectively on the last lower frame, be provided with one at lower frame near the lower end of back link and can drive the location lock that can close, the upper end of front rod is provided with the front limit bar near the upper frame place, is provided with the back gag lever post near the back link place on the upper frame; On pull bar on the upper frame and the back gag lever post universal wheel is housed.
After having adopted forward and backward gag lever post, fold up counterclockwise when making stool and using when maintenance car, the physical efficiency of putting on the shelf reliably is limited in the bench state of setting securely; Again owing on the pull bar of upper frame and back gag lever post universal wheel is housed, when maintenance car was made recumbent bicycle and used, the pad part that goes up on the upper frame was supported by last universal wheel, thereby the effect of strengthening rigidity is arranged.
The utility model will be further described below in conjunction with accompanying drawing
Fig. 1 folds up structural representation front view when making stool and using for the utility model
Fig. 2 folds up for the utility model and does the structural representation vertical view (removing universal wheel and last underlay) that stool uses
Vertical view (removing underlay) when Fig. 3 does the recumbent bicycle use for the utility model
A kind of universal collapsible maintenance car comprises that mainly front rod 1A, back link 1B, upper frame 5, lower frame 8, location lock 9, front limit bar 11, back gag lever post 2 reach part such as universal wheel 7A and 7B up and down.Four front- rear linkage 1A, 1B are connected on the dual-side of lower frame 5 and 8 by hinges 6 respectively, and pad 3 and underlay 10 is housed respectively on the last lower frame 5 and 8, are provided with one at lower frame near the lower end of a back link 1B and can drive the location lock 9 that can close; Front limit bar 11 adopts Type of Welding to be fixed on the upper end of two front rod 1A, and back gag lever post 2 adopts Type of Welding to be fixed on the framework of upper frame 5.Respectively adorn universal wheel 7A on 2 on the pull bar 4 of upper frame and back gag lever post 2, its installation site is symmetrical distribution with the axial line of upper frame 5.
When maintenance car is done the stool use, front and rear connecting rods 1A and 1B be rotated counterclockwise promptly fold up, this moment, front limit bar 11 and back gag lever post 2 can make upper frame 5 reliably be limited in the bench state of setting securely, stop upper frame 5 mobile to counterclockwise again with front rod 1A, the back link 1B hinge 6 on lower frame, location lock 9 cuts out and blocks a back link 1B simultaneously, thereby upper frame 5, front rod 1A, back link 1B also can not move to clockwise direction again, thereby form stable folded state.
When maintenance car is done the recumbent bicycle use, open location lock 9, front rod 1A, back link 1B move to horizontal plane around hinges 6 clockwise directions respectively, on the pull bar 4 of upper frame and the back gag lever post 2 four go up universal wheel 7A kiss the earth at this moment, last pad part is supported by last universal wheel, thereby the effect of strengthening rigidity is arranged.
