Description

Telescoping tube for luggage case

Technical field

This utility model relates to a kind of telescoping tube for luggage case, belongs to suitcase technical field.

Background technology

Draw-bar box occupies an important position in daily life, particularly in travelling.Draw-bar box can make us carry a large amount of the articles for daily use easily.Common draw-bar box is provided with road wheel in bottom, and with telescopic pull bar, facilitates it to walk on level land.Wherein realizing flexible and pull pull bar is most frequently used position.Mostly conventional pull bar is by handle hands, it is arranged on handle button on hand, by the expansion link of button control, upper boom, lower beam is constituted, the pull bar of this structure can realize the flexible and pull under regular situation, but, in use, owing to everyone body constitution is different, in draw process, firmly size also can be variant, when the most overweight, directly upper boom can be completely forced in lower beam, in this process, the impulsive force produced during press-in can be to handle hands and lower beam, upper boom causes damage, as handle ment splits, there is mechanical damage etc. in lower beam or upper boom, and handrail part once breaks down, the normal use of this draw-bar box will be affected.

Based on this, make the application.

Utility model content

In order to overcome the drawbacks described above existing for existing draw-bar box pull bar, this utility model offer is a kind of can spacing, protecting against shock, the telescoping tube for draw-bar box of stable safety.

For achieving the above object, the technical scheme that this utility model is taked is as follows:

Telescoping tube for luggage case, including handle hands, it is positioned at the button in the middle part of handle hands, is positioned at the upper boom of handle hands both sides and coordinates the lower beam installed with upper boom, button connects expansion link, and this expansion link is positioned at upper boom, and with the draw-in groove that arranges on lower beam with the use of；Described handle subordinate side is provided with cover plate, and this cover plate can move up and down along upper boom, and its width is more than lower beam width；Along its cross direction, positive stop strip is installed in lower beam；Positive stop strip and upper boom, cover plate and lower beam coordinating each other, it is achieved the control of upper boom descending depth.

Further, as preferably:

Described upper boom is identical with lower beam cross section structure, and upper boom coordinates and is installed in lower beam, and its cross section structure includes end face, side and bottom surface, and is provided with step trough in the middle part of upper end face and bottom surface, and this step trough highlights up or down.This irregular cross section structure, the beneficially dispersion of impulsive force in drawing process, it is to avoid impulsive force is excessive, affect its mechanical performance.

Described cover plate is the L-shaped structure that one side raises up, and makes the handle hands position unilateral L-shaped structure raised up in the inner, makes handle hands position in the inner.

It is set with protection set on described lower beam, when expansion link contraction, upper boom decline, protection set can be enclosed within draw-in groove；When upper boom is stretched to top, the buckle of expansion link side snaps in draw-in groove, and protection set slides to below draw-in groove.The setting of protection set, it is to avoid dust, granule fall into draw-in groove, affect normally using of draw-in groove.

Detailed description of the invention

Embodiment 1

The present embodiment is for the telescoping tube of luggage case, in conjunction with Fig. 1-Fig. 4, including handle hands 1, it is positioned at the button 2 in the middle part of handle hands 1, is positioned at the upper boom 3 of handle hands 1 both sides and coordinates the lower beam 4 installed with upper boom 3, button 2 connects expansion link 21, this expansion link 21 is positioned at upper boom 3, and with the draw-in groove 41 that arranges on lower beam 4 with the use of；Being provided with cover plate 5 below handle hands 1, cover plate 5 is the unilateral L-shaped structure raised up, and its width is more than the width of lower beam 4；Along its cross direction, positive stop strip 7 is installed in lower beam 4；Positive stop strip 7 cooperates with lower beam 4 with upper boom 3, cover plate 5, it is achieved the control of upper boom 3 descending depth.

In the present embodiment, in conjunction with Fig. 5, upper boom 3 is identical with lower beam 4 cross section structure, and upper boom 3 cooperation is installed in lower beam 4, its cross section structure includes end face a, side b and bottom surface c, and upper end face a relatively bottom surface c width, and in the middle part of bottom surface c, it being provided with step trough d, this step trough d projects upwards；Side b is arcwall face outwardly.This irregular cross section structure, the beneficially dispersion of impulsive force in drawing process, it is to avoid impulsive force is excessive, affect its mechanical performance.

Cover plate 5 is the unilateral L-shaped structure raised up; when sliding at handle hands 1 on cover plate 5, handle hands 1 is whole to be placed in the side that cover plate 5 raises up, and this structure complies with the normal use of push-and-pull work; while protection handle hands 1, it is also avoided to be damaged to operator.

Be set with protection set 6 on lower beam 4, when expansion link 21 shrink, upper boom 3 decline time, protection set 6 can be enclosed within draw-in groove 41；When upper boom 3 is stretched to top, the buckle of expansion link 21 side snaps in draw-in groove 41, and protection set 6 slides to below draw-in groove 41.The setting of protection set, it is to avoid dust, granule fall into draw-in groove 41, affect normally using of draw-in groove 41.
