Description
Technical field
The utility model relates to a kind of travelling case, particularly a kind of variable displacement draw-bar box.
Background technology
At present, existing travelling case is generally fixed volume and has the draw-bar box of telescopic lever and roller, very laborsaving when this draw-bar box drags, and for people's trip brings convenience, becomes the article of indispensability when people's travelling or trip.But its defect is that tank-volumes makes article fail to lay down not when articles they bring in are too much; When articles they bring in are very few, tank-volumes has residue wasting space, and this makes people select to bring worry to the size of be with suitcase when going on a journey.Although there is now the appearance of retractable wagon, this cabinet characteristic is bad, structural instability, makes draw-bar box effectively can not realize the number with articles they bring in and change volume.
Summary of the invention
The technical problem that the utility model mainly solves is the above-mentioned defect how overcoming prior art, effectively realizes draw-bar box volume and the function of change how many with object.For solving the problems of the technologies described above, this variable displacement draw-bar box, comprise telescopic lever, variable casing and guide rail slide block mechanism, casing comprises internal layer case, outer case, internal layer case lid and outer case lid, internal layer case is covered by outer case and bag and opening is relative, internal layer case lid is by outer case lid is coated and opening is relative, internal layer case be provided with two main positioning guide rail slide block mechanisms at the bottom of the case of outer case and be fixedly connected with, main positioning guide rail slide block mechanism comprises guide rail and positioning sliding block, guide rail and outer case are fixed, guide rail is provided with the equal locating hole of more than six or six spacing, positioning sliding block is fixed on internal layer case, positioning sliding block is provided with two spacing holes equal with locating hole spacing on guide rail, with the control panel controlling pin, hole site is limited, inside the tank wall of internal layer case and outer case, both sides are respectively equipped with a secondary supporting guide slide block mechanism, secondary supporting guide slide block mechanism comprises supporting guide and slide block, supporting guide and outer enclosure wall are fixed, slide block is fixed on internal layer tank wall, secondary supporting guide slide block mechanism is used for supporting box, make body structure more stable.
Preferred according to utility model, the material of described variable displacement box body of draw-bar box is rigid plastic sheet.
Preferred according to utility model, the material of described guide rail slide block mechanism is slimmer and more graceful alloy material.
Preferred according to utility model, described telescopic lever, handle, universal wheel, coded lock and connecting band adopt prior art, telescopic lever is provided with button, handle is located at outside internal layer case head, universal wheel is located at bottom outer case, two coded locks are located at the outer wall of internal layer case and internal layer case lid and outer case and outer case lid, and connecting band is located at the junction of internal layer case and internal layer lid and outer case and outer case lid.
The beneficial effects of the utility model: positioning guide rail slide block mechanism adopts the structure of the locating hole of more than six or six, when articles they bring in of going on a journey are too much, by control panel pull-up, slip internal layer case, under suitable volume, select the position of locating hole on guide rail, then guide rail and positioning sliding block control panel are limited; If when article are very few, internal layer case can be slided into least limit position, limit with control panel, have effectively achieved draw-bar box how many and change the function of volume size with article; Secondly, secondary supporting guide slide block mechanism, is fixed on cabinet wall, effectively serves the effect of load-bearing; The utility model structure is simple, stable practical, easy to use.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of variable displacement draw-bar box of the present utility model, comprise telescopic lever 1, casing and guide rail slide block mechanism, the positioning sliding block 8 of main positioning guide rail slide block mechanism is fixed with bottom the internal layer case 3 of casing, positioning sliding block 8 is fixed with loop bar 5, loop bar 5 and internal layer case 3 are connected and fixed, telescopic lever 1 is in loop bar 5, guide rail 11 is fixed with bottom outer case 20, internal layer case 3 inwall is fixed with the slide block 7 of secondary supporting guide slide block mechanism, outer chamber interior wall is fixed with supporting guide 6, coded lock 4 is separately fixed at internal layer case 3, outer case 20, on the outer wall of internal layer case lid 14 and outer case lid 16.Button 13 is fixed on telescopic lever 1, handle 2 is fixed on outside internal layer case 3 head, universal wheel 17 is fixed on the bottom outer wall of outer case 20 and outer case lid 16, and connecting band 15 is fixed on the junction of internal layer case 3 and internal layer case lid 14 and outer case 20 and outer case lid 16.
