Description

Draw-bar box

Technical field

This utility model relates to the technical field of chest, specifically a kind of draw-bar box.

Background technology

Draw-bar box has had become as people's daily travel or the most commonly used article of going on business, and draw-bar box in use also exists two states, i.e. vertical laying state and inclination driving status. So-called inclination driving status refers to that people pull pull bar to make casing inclined in the process of walking, the wheel bottom bottom and ground surface friction, and when vertically laying state mostly is people's short stay, casing is erected on ground.

And existing draw-bar box bottom wheel is divided into the roller and universal wheel that are arranged in pairs. The draw-bar box structure of roller structure is simple and bearing capacity big, therefore firm and durable more, but cannot rotate casing when vertical laying state, therefore operates inconvenience. And the draw-bar box of Universal wheel structure can arbitrarily rotate when draw-bar box is vertical laying state and translate draw-bar box, therefore operate more convenient, but owing to the structure of universal wheel is complex, single universal wheel can bearing capacity little, will cause monolateral universal wheel stress when the inclined driving status of draw-bar box pulls, therefore its service life is shorter.

Summary of the invention

Technical problem to be solved in the utility model is: providing a kind of draw-bar box, it can rotate and translate under vertical laying state, tilt driving status can bearing capacity big, long service life.

Technical solution adopted in the utility model is: provide a kind of draw-bar box, it includes casing, it is characterized in that: box bottom is provided with at least two roller and at least four universal wheel, the position at roller and the nearly wall box place of box bottom is rotatably assorted, universal wheel is installed on box bottom, when casing is vertical direction placement, bottom described universal wheel, the horizontal plane at place is positioned at the lower section of the horizontal plane at idler wheel bottom place, when tilting to when casing that bottom the horizontal plane at idler wheel bottom place and universal wheel, the horizontal plane at place is located in the same horizontal plane the axis of casing with the angle of perpendicular more than 15 degree, and less than 90 degree.

When casing be vertical direction place time described universal wheel bottom the horizontal plane at place to the distance of the horizontal plane at idler wheel bottom place more than 1mm, and less than 20mm.

When casing be vertical direction place time described universal wheel bottom the horizontal plane at place be 10mm to the distance of the horizontal plane at idler wheel bottom place.

When tilting to when casing that bottom the horizontal plane at idler wheel bottom place and universal wheel, the horizontal plane at place is located in the same horizontal plane, the axis of casing is 30 degree with the angle of perpendicular.

Described casing includes case body and case lid, flexibly connecting with case body of case lid, is provided with the spacing band for limiting case lid flip angle between case lid and case body, and one end of spacing band and case body are fixed, and the other end of spacing band and case lid are fixed.

Described spacing band is that elastic material is made.

Described spacing band includes the first spacing band and the second spacing band, one end of first spacing band and case body are fixed, the other end of the first spacing band is provided with the first buckle, one end of second spacing band and case lid are fixed, and the other end of the second spacing band is provided with the second buckle being interlocked with the first buckle on the first spacing band.

After adopting above structure, first draw-bar box of the present utility model compared with prior art has the advantage that, can be translated and rotate by universal wheel at vertical state lower box, easy to operate, and when tilting the roller of casing and earth surface, bearing capacity is big, long service life, secondly, by spacing band be possible to prevent case lid when turning up colliding surface and cause the article breakage being placed on case lid, also avoid case lid contact ground to pollute simultaneously.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

This utility model provides a kind of draw-bar box, it includes casing 1, it is characterized in that: bottom casing 1, be provided with at least two roller 2 and at least four universal wheel 3, bottom roller 2 and casing 1, the position at nearly casing 1 sidewall place is rotatably assorted, universal wheel 3 is installed on bottom casing 1, when casing 1 is placed in vertical direction, bottom described universal wheel 3, the horizontal plane at place is positioned at the lower section of the horizontal plane at place bottom roller 2, when tilting to when casing 1 that bottom the horizontal plane at place bottom roller 2 and universal wheel 3, the horizontal plane at place is located in the same horizontal plane the axis of casing 1 with the angle a of perpendicular 4 more than 15 degree, and less than 90 degree. i.e. angle a >=15 degree, and a < 90 degree.

The structure of above-mentioned multiple rollers 2 is all identical with size, same, and the structure of above-mentioned multiple universal wheels 3 is all identical with size.

When casing 1 is placed in vertical direction bottom described universal wheel 3 horizontal plane at place to the distance h of the horizontal plane at place bottom roller 2 more than 1mm, and less than 20mm.

When casing 1 is placed in vertical direction, bottom described universal wheel 3, the horizontal plane at place is 10mm to the distance h of the horizontal plane at place bottom roller 2.

When tilting to when casing 1 that bottom the horizontal plane at place bottom roller 2 and universal wheel 3, the horizontal plane at place is located in the same horizontal plane, the axis of casing 1 is 30 degree with the angle a of perpendicular.
