Abstract

The utility model relates to a luggage with a foldable single-pipe trolley, which comprises a case body, and a spring structure is mounted on the case body, and a single-pipe trolley is rotatably connected with the spring structure through a rotary pivot. The utility model has the advantages that: when the foldable trolley case is in use, the foldable trolley can be drawn out, so that the case body can be used like an ordinary trolley case; when the trolley is not needed, the trolley is retracted and folded to the top of the case body, consequently, the whole internal space of the case body is not occupied, the neatness of luggage is protected, and materials are saved as well.

Description

A kind of folding single tube bar traveling box

Technical field

The utility model relates to a kind of suitcase, especially a kind of folding single tube bar traveling box.

Background technology

The pull bar of suitcase adopts two-tube structure at present, this makes the bottom space out-of-flatness of box house, it is many to take up room simultaneously, adaptability is poor in actual use, and no matter be single tube or two-tube, all only be installed in the casing the inside and then stretch out outside the casing, exist a pull bar also to take up room equally, just occupy little space, also there is the side out-of-flatness in bottom space.Because the bottom space of existing suitcase is taken and local out-of-flatness by pull bar, cause that to deposit article smooth inadequately, also exist the waste of suitcase inner space simultaneously.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of folding single tube bar traveling box of saving space in the case is provided.

The utility model solves the technical scheme that its technical problem adopts: this folding single tube bar traveling box, comprise casing, and the spring structure is housed on the casing, the spring structure forms rotatable the connection by pivot point with the single tube pull bar.

As preferably, described single tube pull bar comprises tie component one and tie component two, and wherein the bottom of tie component one is provided with retractor device, and tie component one can form with tie component two by retractor device and be slidingly matched.

As preferably, the spring structure is known ball pen press-button structure, comprises spring and connected button, single tube pull bar bottom is provided with the switch cover, be provided with in the switch cover button is carried out spacing trepanning, the retractor device bottom is provided with projection, and projection passes trepanning and can cooperate with button formation.

The effect that utility model is useful is: collapsible pull bar can pull out when in use; casing uses as common draw-bar box; when not using pull bar; pull bar is regained; and folding top of regaining in box body; the inner space integral body of casing does not take, and has protected the planarization of luggage, has saved raw material yet.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: as Fig. 1, this folding single tube bar traveling box comprises casing 1, and spring structure 4 is housed on the casing 1, and spring structure 4 is by 2 one-tenth rotatable connections of pivot point 5 and single tube pull bar shape.Single tube pull bar 2 comprises tie component one 2-1 and tie component two 2-2, and wherein the bottom of tie component one 2-1 is provided with retractor device 6, and tie component one 2-1 can form with tie component two 2-2 by retractor device 6 and be slidingly matched.Spring structure 4 is known ball pen press-button structure, comprise spring 4-2 and connected button 4-1, single tube pull bar 2 bottoms are provided with switch cover 3, be provided with in the switch cover 3 button 4-1 is carried out spacing trepanning 3-1, retractor device 6 bottoms are provided with projection 6-1, and projection 6-1 passes trepanning 3-1 and can cooperate with button 4-1 formation.

During use, as Fig. 2, when the 2 withdrawal bendings of single tube pull bar are placed on the casing, the outstanding a bit about 4 millimeters height of button 4-1; As Fig. 3, when pull bar is pulled directly, the projection 6-1 of retractor device 6 bottoms just in time passes the trepanning 3-1 of switch cover 3 by on button 4-1, and button 4-1 is pressed, and spring 4-2 brings together; As Fig. 4, after pull bar is pulled out, button 4-1 ejects highly higher, about 10 millimeters, reached in the trepanning 3-1, pull bar is pulled out like this, in pulling, button 4-1 switch cover 3 spacing down can bonding tubular tie 2 and spring structure 4 point-blank, guaranteed the force intensity that is subjected to of pull bar simultaneously with pivot point 5; When the pull bar withdrawal, the projection 6-1 on the pull bar is by on button 4-1, and button 4-1 presses the restriction of having broken away from switch cover 3, and pull bar just can be placed on the casing in the bending withdrawal.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
