Description
Technical field
A kind of chest is the utility model is related to, specifically a kind of draw-bar box.
Background technology
Draw-bar box is a kind of conventional trip instrument, is made up of two casing, pull bar and bottom rear rollers, 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 utility model provides a kind of simple in construction, easy to use, push-and-pull labour-saving draw-bar box.
The technical solution of the utility model is：A kind of draw-bar box, including casing, the bottom four corners of casing are provided with universal wheel,
It is characterized in that：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, and support bar rotation is bonded box back surface, pull bar synchronous rotary patch
Box back surface is closed, push-and-pull roller is not less than universal wheel, and now casing is normal configuration draw-bar box；When storing is heavier in casing,
Support bar and pull bar are rotated, makes support bar vertical support box back surface, push-and-pull roller lands, and pull bar stretches out, case supports
It is in that bottom half universal wheel is hanging, and upper shelf leans against on pull bar or be connected to push-and-pull parallel to the state of ground on support bar
On bar, support bar, pull bar, casing top form 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 the utility model structure diagram；
Fig. 2 is Fig. 1 use state figure.
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 four corners are 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, and two
Coaxially the be hinged lower end of two pull bar 4 and two push-and-pull rollers 5, pull bar are adjustable pushing pull bar to the lower end of support bar 3.
In order to ensure the stability of strutting system of support bar, it can set up more support bars at box back surface and be fitted in box back surface and hang down
Straight connection support bar, the mechanism on fastening connection casing top can be also set up on pull bar, in order under casing horizontality
Fastening connection ensures the stability of casing horizontal support.
