Description
Technical field
The present invention relates to a kind of chest, specifically a kind of draw-bar box.
Background technology
Draw-bar box is a kind of conventional trip instrument, is made up of casing, two rollers of pull bar and bottom rear, its shortcoming
It is：When casing storage is heavier, user's horizontal sliding or horizontal drawing are more laborious.
The content of the invention
The invention provides a kind of simple structure, easy to use, push-and-pull labour-saving draw-bar box.
The technical scheme is that：A kind of draw-bar box, including casing, the bottom corner of casing are provided with universal wheel, and it is special
Levy and be：Also include support bar, pull bar, push-and-pull roller, the middle part or middle and lower part hinged support bar upper end at casing back, support
Bar lower end is coaxially hinged pull bar lower end and push-and-pull roller.
Further, the middle part at the casing back or the side of middle and lower part two are respectively articulated with two post uppers, two supports
Bar lower end is coaxially hinged two pull bar lower ends and two push-and-pull rollers.
Yet further, the pull bar is adjustable pushing pull bar.
When normal, adjustable pushing pull bar is contraction state, support bar rotation laminating box back surface, pull bar synchronous rotary patch
Box back surface is closed, push-and-pull roller is not less than universal wheel, now casing is normal configuration draw-bar box；When storing is heavier in casing,
Rotation support bar and pull bar, make support bar vertical support box back surface, push-and-pull roller land, and pull bar stretches out, case supports
It is in that, parallel to the state of ground, bottom half universal wheel is hanging, and upper shelf leans against on pull bar or be connected to push-and-pull on support bar
On bar, support bar, pull bar, casing top constitute stable triangle structure, by push-and-pull roller pull bar extension bar promotion
Or pull lower drive casing quickly to move, it is easy to use, laborsaving.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the use state figure of Fig. 1.
Specific embodiment
It is described further below in conjunction with drawings and Examples.
Fig. 1, shown in 2：A kind of draw-bar box, including casing 1, universal wheel 2, support bar 3, pull bar 4, push-and-pull roller 5, casing
1 bottom corner is provided with universal wheel 2, and the middle part or the side of middle and lower part two at the back of casing 1 are respectively articulated with the upper end of two support bar 3, two
The lower end of support bar 3 is coaxially hinged the lower end of two pull bar 4 and two push-and-pull rollers 5, and pull bar is adjustable pushing pull bar.
In order to ensure the stability of strutting system of support bar, can box back surface set up many support bars be fitted in box back surface hang down
Straight connection support bar, can also set up the mechanism for buckling connection casing top, in order under casing horizontality on pull bar
Buckling connection ensures the stability of casing horizontal support.
