Background technology
The bar traveling box bag is a practical tool very in going out, travelling, and is subjected to consumer's welcome deeply.Yet, the set roller of tradition trolley luggage exposes to the casing outside, and the roller that exposes is easy to damage because of the collision of external force in the process of trolley luggage collection or carrying, and the roller that exposes also takies certain volume, thereby has influence on the convenience of trolley luggage collection or carrying.In order to address this problem, the patent No. is that 00242555.6 utility model patent discloses a kind of " the draw-bar box hired car of tool rocker-arm expanding pulley ".This draw-bar box hired car on casing, be provided with one can ccontaining roller wheel seat, on wheel seat, be pivoted with a wheel carrier in order to the roller that is pivoted, in wheel seat, be provided with a coupled frame that can move relative to the wheel seat vertical lift again, and rocking arm is pivoted between coupled frame and wheel carrier, in casing, be provided with in addition one can with the retaining pipe of pull bar interlock, and between retaining pipe and coupled frame, be provided with a trace, and reach the effect of flexible roller, reduced volume whereby.But this draw-bar box hired car number of spare parts is many, complex structure, making difficulty.
Summary of the invention
The technical problems to be solved in the utility model is to provide the pull rod device of a kind of luggage with scalable roller, it is simple in structure, easy to use, can make when folding telescopic lever in the roller withdrawal wheel box, roller is broken when avoiding collection or carrying, also can dwindle the volume of bar traveling box bag simultaneously.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
Luggage of the present utility model is with the pull rod device of scalable roller, mainly include draw-bar seat, sleeve pipe and end are fixed with the telescopic lever of handle, telescopic lever can insert in the sleeve pipe, described sleeve bottom position is provided with one and takes turns box, be provided with gear in the wheel box, the bottom is fixed with the wheel carrier of roller, penetrate sleeve pipe gathering sill wherein and penetrate wherein wheel carrier gathering sill for sleeve pipe for wheel carrier, these gathering sills are parallel to each other, gear is between sleeve pipe and wheel carrier, be embedded with the tooth bar that is meshed with gear at sleeve pipe and wheel carrier respectively near on the lateral wall of gear, sleeve pipe and wheel carrier are by the rack-and-pinion engaged transmission; Described draw-bar seat is provided with and can penetrates wherein gathering sill for sleeve pipe, and sleeve pipe passes draw-bar seat, inserts in the wheel box.
Described sleeve bottom is provided with alignment pin, does not have the sidewall of tooth bar at sleeve pipe, on the corresponding alignment pin position, offers and wears mouth, is provided with locating hole near the sleeve pipe gathering sill wearing mouthful, and alignment pin can pass and mouthful be sticked in locating hole.
The outer end of described alignment pin establishes one can protrude out the projection that is sticked in locating hole on the sleeve pipe gathering sill outward, is provided with in top side, alignment pin stage casing and establishes a spring between oblique surface, the inner and the internal surface of sleeve pipe; Oblique surface position, corresponding alignment pin stage casing, described telescopic lever bottom is provided with and protrudes out pin, is provided with beveled edge in the bottom that protrudes out pin.
Telescopic lever of the present utility model folds when being inserted into sleeve bottom, telescopic lever protrudes out under the beveled edge of pin and is pressed on the oblique surface in alignment pin stage casing, making alignment pin overcome inner spring force breaks away from locating hole and is withdrawn in the sleeve pipe, then, sleeve pipe moves down along gathering sill under the promotion of telescopic lever, and move simultaneously with the wheel carrier of quill gear tooth bar engaged transmission, the roller that is fixed on the wheel carrier bottom is retracted in the wheel box.So, can avoid roller in handling process, to be broken, and suitably dwindle the volume that takies of trolley luggage.
When telescopic lever launches to use, the beveled edge that telescopic lever protrudes out pin breaks away from the oblique surface on the alignment pin, make alignment pin under inner spring force effect, contact is on gathering sill, and when sleeve pipe moved on the gathering sill of telescopic lever pulling lower edge, wheel carrier moved down simultaneously, finally when moving on to position of positioning hole on the sleeve pipe, alignment pin is inserted under the spring force effect and forms the location in the locating hole, takes turns outside the box thereby roller is stretched out and be fixed on.
In sum, luggage of the present utility model has following advantage with the pull rod device of scalable roller: simple in structure, can when folding telescopic lever, make in the roller withdrawal wheel box, break roller when avoiding collection or carrying, and dwindle the luggage volume.
Description of drawings
Fig. 1 is the structural representation of pull rod device of the present utility model when being collapse state;
Fig. 2 is that pull rod device of the present utility model is the structural representation when launching user mode.
The specific embodiment
As depicted in figs. 1 and 2, luggage of the present utility model is with the pull rod device of scalable roller, include draw-bar seat 1, sleeve pipe 2 and end are fixed with the telescopic lever 4 of handle 3, telescopic lever 4 can insert in the sleeve pipe 2, be provided with one at sleeve pipe 2 bottom positions and take turns box 5, be provided with gear 6 in the wheel box 5, the bottom is fixed with the wheel carrier 8 of roller 7, and the sleeve pipe gathering sill 9 and the wheel carrier gathering sill 10 that supply sleeve pipe 2 and wheel carrier 8 to penetrate wherein and be parallel to each other respectively, its middle gear 6 is between sleeve pipe 2 and wheel carrier 8, lateral wall at sleeve pipe 2 and wheel carrier 8 close gears 6 is embedded with cover pipe rack 11 and the wheel carrier tooth bar 12 that is meshed with gear 6 respectively, and sleeve pipe 2 passes through the rack-and-pinion engaged transmission with wheel carrier 8; Be provided with on draw-bar seat 1 and can penetrate wherein gathering sill 13 for sleeve pipe 2, sleeve pipe 2 passes draw-bar seat 1, inserts in the wheel box 5.
