Abstract
The utility model relates to a telescopic draw-bar box. Most of traditional draw-bar boxes are fixed in structures, the volume can not be changed along with the quantity of carried articles; and the carried articles cannot be contained if the carried articles are too many in travel, and a space is wasted if the carried articles are fewer. Therefore, the telescopic draw-bar box comprises a draw bar and a box body, wherein the box body comprises an upper box body and a lower box body; openings of the upper box body and the lower box body are opposite; the opening directions are parallel to the draw bar; at least two layers of telescopic expansion box bodies are arranged between the upper box body and the lower box body; each expansion box body comprises a first layer of expansion box body and a second layer of expansion box body; a fastener for stretching is arranged between the first layer of expansion box body and the second layer of expansion box body; a control button for controlling expansion of the expansion box bodies is arranged on the draw bar; and a zip fastener and a handle are arranged on the upper box body. The telescopic draw-bar box is simple in structure, scientific in design and convenient to use, the volume of the box body can be adjusted according to the quantity of the carried articles, and good practical application value and promotional value are achieved.
Description
Technical field
The utility model relates to a kind of draw-bar box, particularly a kind of telescopic lever case.
Background technology
The travelling draw-bar box that present people know is the pull bar that wheel is installed in the bottom of each chest and can stretches, and this draw-bar box is recoverable to, and saves the space, and is very laborsaving when dragging, and its invention offers convenience for people's travelling life.But the most structures of existing draw-bar box are fixed, can not be along with what and the variable volume of carrying object, and more then can not pack into if whilst on tour carries object, if carry the less wasting space again of object, can not satisfy people's demand.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and a kind of telescopic lever case of volume adjustable is provided.
For solving the problems of the technologies described above, this telescopic lever case comprises pull bar and casing, and casing comprises layer box body and following layer box body, the opening of last layer box body and following layer box body is relative and opening direction is parallel with pull bar, is provided with telescopic two-layer at least expansion cabinet between last layer box body and the following layer box body.
During trip, when carrying object when less, expansion cabinet can be withdrawn, volume is reduced to minimum, be easy to carry; When carrying object when more, can draw back the different layers expansion cabinet according to the size of carrying the object amount, easy to use.
So design can be according to the big or small adjusting tank body bulk that carries the object amount.
As optimization, expansion cabinet comprises ground floor expansion cabinet and second layer expansion cabinet, is provided with between ground floor expansion cabinet and the second layer expansion cabinet for flexible holding firmware.So design is convenient to install, and easy to use.
As optimization, pull bar is provided with for the flexible control button of control expansion cabinet.So design is convenient to control the flexible of expansion cabinet.
As optimization, last layer box body is provided with slide fastener and portable.So design is easy to use.
The utility model telescopic lever case, simple in structure, design science, easy to use can have actual application value and promotional value preferably according to the big or small adjusting tank body bulk that carries the object amount.
Description of drawings
