Description
Technical field
The utility model is related to a kind of luggage case, more particularly to a kind of portable stair climbing luggage case.
Background technology
Being lifted using the luggage case of climbing stairs can be conveniently many compared with heavy articles, but the luggage case of climbing stairs is simultaneously at present
Do not popularize, major influence factors have the ability and service life on product adaptation road surface, by taking triangle wheeled luggage as an example, are only suitable for
Pull underloading article and linkage is poor, quick walking is difficult on scraggly road surface, physical life is short.In the market
There is built-in belt luggage case, the shortcoming of this kind of luggage case easily scratches the lower surface of casing when being walking, and damping is imitated
It is really bad.
Utility model content
The purpose of this utility model is a kind of portable stair climbing luggage case of offer, solves asking for luggage case stair climbing
Topic, and can adapt to scraggly road surface.
In order to solve the above problems, the utility model provides a kind of portable stair climbing luggage case, including casing, is located at
Support on casing, it is connected to and is used for the elastic component and the walking unit located at mid-stent that control support folding on support.Institute
State first connecting rod and third connecting rod that support is connected to including track frame, two ends on track frame and casing；The track frame
Elastic component is provided between third connecting rod.
The support has the state of opening and closing with casing relatively, and the elastic component controls the folding angle of support, the row
Walk the friction that unit avoids support and ground or other contact surfaces.
Further, the support also includes second connecting rod, and the track frame, first connecting rod, second connecting rod and the 3rd connect
Bar is sequentially hinged, and forms linkage.
Further, the second connecting rod is fitted with casing, and the first connecting rod and second connecting rod pass through third connecting rod
It is connected with casing.
Further, the elastic component includes the nitrogen spring that two ends are connected on track frame and third connecting rod,
The velocity-stabilization when upholding of nitrogen spring.
Further, the walking unit includes the Athey wheel on track frame and the crawler belt of annular.
Further, in addition to the guide located at track frame end, during stair climbing the guide first with stair
Contact, directly collides with stair so as to avoid crawler belt and produces impulsive force.
Further, the casing includes being formed on body and pull bar and universal wheel on body, the body
The support, and provided with the groove for placing support and guide.
Compared with prior art, there is following technique effect in the utility model：
1st, the application realizes the function of stair climbing using external caterpillar belt structure, while adaptation of the caterpillar belt structure to contact surface
Property is good, therefore the utility model can adapt to scraggly ground.
2nd, luggage case is substituted for other housing pieces, it is also frequent in daily life except being used when removal of home, travelling
Use, such as the elderly early get on food market buy vegetables, to student as school bag use.
3rd, the support of the application is folding, can be taken in the groove of the body under non-stair climbing state, occupancy
Space very little, is used easily.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the utility model.
Wherein：1st, casing, 11, groove, 21, track frame, 22, first connecting rod, 23, second connecting rod, 24, third connecting rod, 3,
Nitrogen spring, 4, directive wheel, 51, crawler belt, 52, Athey wheel.
Embodiment
Below in conjunction with accompanying drawing, lift a specific embodiment and described in detail.
As shown in figure 1, the application includes casing 1, the support on casing 1, is connected on support for controlling support
The elastic component of folding, the guide on support and the walking unit located at mid-stent.
The casing 1 includes body and pull bar and universal wheel on body, and pull bar and universal wheel are easy in common road
Pushed box on road.Body is provided with groove 11, for placing support and guide.The support includes two groups of shoes being sequentially connected with
Tape holder 21, first connecting rod 22, second connecting rod 23 and third connecting rod 24 are sequentially hinged, and form two groups of linkages, two groups of connecting rod machines
It is attached between structure by connecting plate, the end of the connecting plate is fixed on an even track frame 21.In every group of linkage,
Second connecting rod 23 is fitted with the body, and elastic component, i.e. nitrogen spring 3 are provided between third connecting rod 24 and track frame 21.Nitrogen
The extension speed of spring 3 is more stable, to support without too strong impulsive force.In stair climbing or walking process, connecting rod machine
Structure can play cushioning effect to vibrations to a certain extent, directly be connected much with casing 1 than nitrogen spring 3.Crawler belt
Frame 21 is in the shape of channel-section steel, is made up of the backplate and middle bottom plate of both sides, backplate is used to connect nitrogen spring 3, third connecting rod
24 grade parts, bottom plate is used to connect walking unit, i.e. Athey wheel 52 and crawler belt 51.Elongated hole, the both sides of elongated hole are provided with bottom plate
The mounting seat of Athey wheel 52 is disposed with, for installing Athey wheel 52.Crawler belt 51 is circularized, and is tensioned by Athey wheel 52.Track frame
21 end connection guide, i.e. directive wheel 4, the backward wheel passes through axle and bearing connecting band track frame 21.The process of stair climbing
In, directive wheel 4 is contacted with stair first, so that avoid crawler belt 51 directly produces impulsive force with stair collision.
Under off working state, the support and guide are taken in the groove 11 of body, when running into stair, are broken manually
Connecting plate, nitrogen spring 3 is upheld automatically, is made track frame 21 and the formation certain angle of casing 1, is then lifted pull bar, just realize
The function of stair climbing.
The application realizes the function of stair climbing using external caterpillar belt structure, while adaptability of the caterpillar belt structure to contact surface
It is good, therefore the utility model can adapt to scraggly ground.Luggage case is substituted for other housing pieces, except removing
Family, travelling when use, also often used in daily life, such as the elderly early get on food market buy vegetables, to student as book
Bao Yong.
Disclosed above is only the specific embodiment of the application, but the application is not limited to this, any this area
Technical staff can think change, should all fall in the protection domain of the application.
