Description
Technical field
Present invention relates particularly to a kind of trolley case.
Background technology
At present, when people travel outdoors or do shopping, a trolley case is often used.Common trolley case is in bottom
Equipped with traveling wheel, and telescopic pull rod is carried, facilitate it to walk on level land.But when in stair activity or running into barrier
When hindering thing, easily by the bottom of trolley case and stairway step or barrier grazing, so as to cause to damage to trolley case.At this time, still
It is old to need manpower to lift trolley case, cause trolley case to lose the effect of its is portable, laborsaving, can not have while babinet is pulled
Imitate avoiding obstacles or stair activity step.This, which is always one, effectively to be solved the problems, such as.
And for example Fig. 1, is a kind of existing draw-bar box structure.Although the structure is turned with reality by three wheel axles of both sides
Existing stair activity, still, its babinet is directly anchored in connecting shaft, in stair activity, it is necessary to larger drawing force, and
And it is possible to grazing occurs between stair.Existing this structure still Shortcomings.
The content of the invention
The defects of to overcome present in the prior art, now provide a kind of trolley case, smoothly convenient upper and lower to solve trolley case
The problem of stairway step or avoiding obstacles, and further improve the Labor-saving portable of trolley case.
To achieve the above object, there is provided a kind of trolley case, including：
Pull rod, is arranged at the back side of trolley case and has hinged end, the bottom surface of trolley case is extended in hinged end；
Multiple transmission struts, apical support are connected to hinged end；
Connecting shaft, wears the bottom for being fixed in multiple transmission struts；
At least two rolling wheel supports, are movably set in the both ends of connecting shaft respectively, and each rolling wheel support includes at least three
Roller fixing end, roller fixing end are located on the same circumference of different azimuth；
Multiple rollers, each rotation axis is connected to roller fixing end respectively.
A kind of beneficial effect of trolley case of the present invention is,
By setting transmission strut in connecting shaft, the level height of pull rod bottom is directly high higher than the level of connecting shaft
Degree, so as to form the arm of force between pull rod and connecting shaft, when trolley case wanted during pulling stair activity step or
During avoiding obstacles, leverage is produced by the arm of force of formation so that pull rod is not to lift or pull rigidly connecting shaft, and
It is in the case of labour-saving so that the light axis of connecting shaft turns, and then drives the roller on rolling wheel support successfully to climb over step or barrier
Hinder thing.
Preferably, the bottom of pull rod has a support bridge, and the top for being driven strut is fixed on support bridge.
Preferably, the either end of connecting shaft has at least two transmission struts, and adjacent drive strut forms angle and converges
It is poly- to be connected in connecting shaft.
Preferably, rolling wheel support includes extending in different directions and one end converges at multiple struts of connecting shaft, and adjacent two
The angle of the angle formed between a strut is identical, and the other end of each strut extends outwardly to form roller fixing end.
Brief description of the drawings
Fig. 1 is the structure diagram of existing trolley case；
Fig. 2 is a kind of side structure schematic diagram of trolley case of the present invention.
Embodiment
For the benefit of to the understanding of structure of the invention, illustrate with reference to the accompanying drawings and embodiments.
With reference to Fig. 1, for the structure diagram of existing trolley case.With reference to Fig. 2, for a kind of side structure of trolley case of the present invention
Schematic diagram.
As shown in Fig. 2, on the basis of Fig. 1, the present invention provides a kind of trolley case, including：Pull rod 2, is arranged at pull rod
The back side of case 1 simultaneously has hinged end, which extends the bottom surface of trolley case 1；Multiple transmission struts 4, apical support connection
In the hinged end of pull rod 2；Connecting shaft 3, wears the bottom for being fixed in multiple transmission struts 4；At least two rolling wheel supports 5, respectively
The both ends of connecting shaft 3 are sheathed on, each rolling wheel support 5 includes at least three roller fixing ends, and roller fixing end is positioned at not Tongfang
On the circumference of position；Multiple rollers 6, each rotation axis is connected to roller fixing end respectively.
Specifically, the bottom of pull rod 2 has a support bridge 7, and the top of transmission strut 4 is fixed on support bridge 7.Even
The either end of spindle 3 has at least two transmission struts 4, and adjacent drive strut 4, which forms angle and converges, is connected to connecting shaft 3
On.Rolling wheel support 5 includes extending in different directions and one end converges at multiple struts 50 of connecting shaft, two neighboring strut 50 it
Between the angle that is formed be 120 °, the other end of each strut 50 extends outwardly to form roller fixing end.
After with said structure feature, with reference to shown in Fig. 1 and Fig. 2, the present invention can be implemented by procedure below：
By the architectural feature between above-mentioned each component, installation forms a complete trolley case.Wherein, especially it is noted that：
Need in the affixed support bridge 7 in the bottom of pull rod 2, angled therebetween two transmission struts 4 be respectively and fixedly connected with support bridge 7 and
The back side of trolley case 1.Meanwhile the both ends of connecting shaft 3 are respectively and fixedly connected with two transmission struts 4.With this, drawn when being dragged by pull rod 2
During rod box 1, the level height of 2 bottom of pull rod will directly be higher than the horizontal plane of the level height, even above step of connecting shaft 3,
Due to lever arm of force principle, and then preferably drive 3 axis of connecting shaft to turn, realize more preferably labour-saving effect.
After completing above-mentioned implementation process, the following characteristics of the present invention should be able to be embodied：
By setting transmission strut in connecting shaft, the level height of pull rod bottom is directly high higher than the level of connecting shaft
Degree, so as to form the arm of force between pull rod and connecting shaft, when trolley case wanted during pulling stair activity step or
During avoiding obstacles, leverage is produced by the arm of force of formation so that pull rod is not to lift or pull rigidly connecting shaft, and
It is in the case of labour-saving so that the light axis of connecting shaft turns, and then drives the roller on rolling wheel support successfully to climb over step or barrier
Hinder thing.
The present invention is described in detail above in association with attached drawing embodiment, those skilled in the art can be according to upper
State and bright many variations example is made to the present invention.Thus, some details in embodiment should not form limitation of the invention, this
Invention will be used as protection domain using the scope that the appended claims define.
