Abstract
The utility model provides a kind of luggage case, comprising: pull bar, is arranged at the back side of draw-bar box and has hinged end, and hinged end extends the bottom surface of draw-bar box; Multiple transmission strut, apical support is connected to hinged end; Connecting axle, wears the bottom being fixed in multiple transmission struts; At least two rolling wheel supports, are movably set in the two ends of connecting axle respectively, and each rolling wheel support comprises at least three roller stiff ends, and roller stiff end is positioned at the circumferentially same of different azimuth; Multiple roller, turning cylinder is connected to roller stiff end respectively separately.The utility model solves the problem of the smooth convenient stair activity step of draw-bar box or avoiding obstacles, and improves the Labor-saving portable of draw-bar box further.
Description
Technical field
The utility model is specifically related to a kind of luggage case.
Background technology
At present, when people travel outdoors or do shopping, often can use a draw-bar box case.Common draw-bar box is provided with road wheel in bottom, and with telescopic pull bar, facilitates it to walk on level land.But, when at stair activity or when running into barrier, easily by the bottom of the case of draw-bar box with stairway step or barrier grazing, thus damage is caused to draw-bar box.Now, still need manpower to be mentioned by draw-bar box, it is portable, labour-saving effect to cause draw-bar box to lose, cannot while pulling casing effective avoiding obstacles or stair activity step.This is a problem that could not obtain effectively solving always.
As Fig. 1, it is existing a kind of draw-bar box structure.Although this structure turns to realize stair activity by three wheel axles of both sides, its casing is directly fixed on connecting axle, when stair activity, needs larger drawing force, and, still likely and between stair there is grazing.Existing this structure still Shortcomings.
Utility model content
For overcoming the defect existing for prior art, now providing a kind of luggage case, to solve the problem of the smooth convenient stair activity step of draw-bar box or avoiding obstacles, and improving the Labor-saving portable of draw-bar box further.
For achieving the above object, a kind of luggage case is provided, comprises:
Pull bar, is arranged at the back side of draw-bar box and has hinged end, and hinged end extends the bottom surface of draw-bar box;
Multiple transmission strut, apical support is connected to hinged end;
Connecting axle, wears the bottom being fixed in multiple transmission struts;
At least two rolling wheel supports, are movably set in the two ends of connecting axle respectively, and each rolling wheel support comprises at least three roller stiff ends, and roller stiff end is positioned at the circumferentially same of different azimuth;
Multiple roller, turning cylinder is connected to roller stiff end respectively separately.
The beneficial effect of the utility model luggage case is,
By arranging transmission strut on connecting axle, the level height of pull bar bottom is directly higher than the level height of connecting axle, thus the arm of force is defined between pull bar and connecting axle, when draw-bar box wants stair activity step or avoiding obstacles in the process pulled, leverage is produced by the arm of force formed, pull bar is made not to be lift rigidly or pull connecting axle, but in the situation of labour-saving, make the light axle of connecting axle turn, and then the roller on rolling wheel support is driven successfully to climb over step or barrier.
Preferably, the bottom of pull bar has a support bridge, and the top of transmission strut is fixed on support bridge.
Preferably, any one end of connecting axle has at least two transmission struts, and adjacent drive strut forms angle and converges and is connected on connecting axle.
Preferably, rolling wheel support comprises and to extend and one end converges at multiple poles of connecting axle along different directions, and the angle of the angle formed between adjacent two poles is identical, and the other end of each pole stretches out to form roller stiff end.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing draw-bar box;
Fig. 2 is the side structure schematic diagram of the utility model luggage case.
Detailed description of the invention
For the benefit of to the understanding of structure of the present utility model, be described below in conjunction with drawings and Examples.
With reference to Fig. 1, it is the structural representation of existing luggage case.With reference to Fig. 2, it is the side structure schematic diagram of the utility model luggage case.
As shown in Figure 2, on the basis of Fig. 1, the utility model provides a kind of luggage case, comprising: pull bar 2, is arranged at the back side of draw-bar box 1 and has hinged end, and this hinged end extends the bottom surface of draw-bar box 1; Multiple transmission strut 4, apical support is connected to the hinged end of pull bar 2; Connecting axle 3, wears the bottom being fixed in multiple transmission struts 4; At least two rolling wheel supports 5, are sheathed on the two ends of connecting axle 3 respectively, and each rolling wheel support 5 comprises at least three roller stiff ends, and roller stiff end is positioned at different azimuth circumferentially; Multiple roller 6, turning cylinder is connected to roller stiff end respectively separately.
Particularly, the bottom of pull bar 2 has a support bridge 7, and the top of transmission strut 4 is fixed on support bridge 7.Any one end of connecting axle 3 has at least two transmission struts 4, and adjacent drive strut 4 forms angle and converges and is connected on connecting axle 3.Rolling wheel support 5 comprises and to extend and one end converges at multiple poles 50 of connecting axle along different directions, and the angle formed between adjacent two poles 50 is 120 °, and the other end of each pole 50 stretches out to form roller stiff end.
After having said structure feature, shown in composition graphs 1 and Fig. 2, the utility model can be implemented by following process:
By the architectural feature between above-mentioned each component, the luggage case that formation one is complete is installed.Wherein, especially it is noted that: need in the bottom of pull bar 2 an affixed support bridge 7, two the transmission struts 4 being mutually angle are fixed in the back side of support bridge 7 and draw-bar box 1 respectively.Meanwhile, the two ends of connecting axle 3 affixed two transmission struts 4 respectively.With this, when dragging draw-bar box 1 by pull bar 2, the level height of pull bar 2 bottom is by the direct level height higher than connecting axle 3, even higher than the horizontal plane of step, due to lever arm of force principle, and then drive connecting axle 3 axle to turn better, realize better labour-saving effect.
After completing above-mentioned implementation process, following characteristics of the present utility model should be able to be embodied:
By arranging transmission strut on connecting axle, the level height of pull bar bottom is directly higher than the level height of connecting axle, thus the arm of force is defined between pull bar and connecting axle, when draw-bar box wants stair activity step or avoiding obstacles in the process pulled, leverage is produced by the arm of force formed, pull bar is made not to be lift rigidly or pull connecting axle, but in the situation of labour-saving, make the light axle of connecting axle turn, and then the roller on rolling wheel support is driven successfully to climb over step or barrier.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain.
