Nowadays draw-bar box on the market is mostly two wheel constructions, the four-wheel draw-bar box is only also the problem that can't vertically place in order to solve draw-bar box, and while dragging draw-bar box, angle due to the draw-bar box inclination, people not only need to overcome the resistance produced while dragging draw-bar box, also need bearing a part of gravity of draw-bar box, therefore when luggage is more, dragging draw-bar box can make hand more easily tired, if ground relief, shake frequently while dragging draw-bar box, more aggravated tired degree.
The utility model content
Technical problem to be solved in the utility model just is to provide and a kind ofly drags easily, absorbing vibration, be difficult for tired four-wheel draw-bar box.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of four-wheel draw-bar box, comprise the draw-bar box body, it is characterized in that: described draw-bar box body both sides are provided with cavity, the described cavity inner wall axle piece that is connected, described axle piece comprises steel disc section and axial region, described axial region is flexibly connected wheeled resilient legs, and the described wheeled resilient legs outside is provided with the stop collar be fixed on axial region, and described axial region end face is provided with the elastic force lever.
Preferably, described wheeled resilient legs comprises two single legs that be arranged in parallel, and two single legs are connected with cross bar.Cross bar makes two single legs remain parallel.
Preferably, described single leg comprises housing, and described housing is the barrel shape aluminium-alloy pipe, and the lower end outer wall is provided with external screw thread.The aluminium-alloy pipe quality is light.
Preferably, bottom surface, described housing top is provided with connecting portion, and described connecting portion is provided with a macropore and some apertures.Some apertures can be adjusted the angle of inclination of wheeled resilient legs as required.
Preferably, in described housing, be provided with spring, described spring one end is against the housing intracavity bottom, and the other end is against caster.Spring act as load-bearing and damping.
Preferably, described caster comprises cylindrical portion and support, and described support connects wheel by bearing.
Preferably, described cylindrical portion bottom surface, against capping, is provided with screw and through hole in described capping, and described screw is fixed on housing by external screw thread, and described support is through through hole.Capping prevents that the cylindrical portion of caster from deviating from housing.
Preferably, described elastic force lever comprises base and lever, and described base is secured by bolts in the axial region upper surface, and described lever head end is provided with protuberance, and described protuberance can embed aperture.Protuberance embeds when aperture can make wheeled resilient legs adjust to correct position and can not rotate.
Preferably, described draw-bar box body bottom surface is provided with tread plate.Can make draw-bar box vertically place, and there is antiskid function.
The utility model is by being improved draw-bar box structure, increased wheeled resilient legs, make draw-bar box longitudinally a part of gravity be supported, the spring of wheeled resilient legs can absorb the vibrations that the overwhelming majority causes because of Uneven road, the cavity of draw-bar box body both sides can be taken in wheeled resilient legs, the utlity model has simple in structure, drag easily, absorbing vibration, be difficult for tired advantage.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is side view of the present utility model;
Fig. 2 is connecting portion and each member connection structure schematic diagram in the utility model;
