Abstract
The invention discloses a novel effort-saving draw-bar box which comprises a main box body (1), a draw bar (2), a movable hinge (3) and wheels (4). The whole box body of the draw-bar box is placed on the ground in parallel and the draw bar is connected with the main box body (1) through the movable hinge; and when the draw bar (2) is pulled, the draw bar (2) is obliquely and upwardly pulled to pull the main box body (1) to horizontally move forwards, so that the weight of the main box body (3) is completely applied to the ground, the draw bar (2) only needs to bear a pulling force for pulling the box body without a pressure of the main box body (1) on the draw bar (2), and cannot be bent by pressing and broken off even if the draw bar is in a pulled state, the service life of the draw-bar box is greatly prolonged, and the difficult problems of damage and inconvenience for carrying due to heavy luggage in the draw-bar box are solved.
Description
Technical field
The present invention relates to a kind of draw-bar box, the comprehensive Labor-saving pull rod case landing of especially a kind of casing.
Background technology
Rod-pulling type luggage case is Out Traveler's ordinary articles at present, especially long-distance travel and the student that attends school outside, on market, existing draw-bar box all adopts the mode of oblique pull, no matter be built-in pull bar or external pull bar, the gravity of casing itself just directly acts on pull bar itself like this, make pull bar for a long time in by pressure condition, even backfin of very easy press-bending, cause unnecessary economic loss, and carry and carry inconvenience, bring unnecessary trouble to journey, affect the pleasure mood of journey.
Summary of the invention
In order to address the above problem, the invention discloses a kind of new-type Labor-saving pull rod case, the present invention makes the casing of draw-bar box be parallel to ground completely, then hauling casing level by pull bar moves ahead, alleviate the portable weight of user, reduce greatly the pressure that pull bar bears, increased the service life of draw-bar box.
The object of the present invention is achieved like this:
A new-type Labor-saving pull rod case, comprising: 1, main box, 2, pull bar, 3, hinges, 4, wheel.
Above-mentioned a kind of new-type Labor-saving pull rod case, described main box 1 entirety is parallel to ground.
Above-mentioned a kind of new-type Labor-saving pull rod case, described pull bar 2 is connected with main box 1 by hinges 3.
Because the present invention is by parallel being put on ground of casing entirety of draw-bar box, then pull bar is connected with main box 1 by hinges, while pulling pull bar 2, pull bar 2 pulls main box 3 levels to advance obliquely, the weight of main box 3 own just puts on ground completely like this, 2 needs of pull bar bear the pulling force that pulls casing, and there is no the pressure of main box 1 to pull bar 2 itself, even if pull bar 2 also can not be bent in the time of extended state, more can not fracture, greatly increase the service life of draw-bar box, solve the damage that draw-bar box causes because luggage is heavy and carried an inconvenient difficult problem.
Brief description of the drawings
Fig. 1 is the mechanical analysis of existing draw-bar box.
Fig. 2 is structural representation of the present invention.
In figure: 1 main box, 2 pull bars, 3 hinges, 4 wheels.
Detailed description of the invention
