Description
Technical field
The utility model belongs to the folding castor of a kind of case and bag.
Background technology
Traditional casing transportation is completed with the wheel car, uses and carry equal inconvenience.Though a kind of less case and bag are arranged at the bottom belt wheel, take turns little and fix, crank when dragging case and bag, the easy overturning of case and bag, the case and bag transportation is also inconvenient.
Summary of the invention
The purpose of this utility model is the folding castors of a kind of case and bag of design, makes the castor of case and bag or casing collapsible, have simple in structure, reasonable in design, folding and easy to use, the advantage that result of use is good.
For this reason, the utility model mainly is comprised of fixed head and wheel, and four jiaos of fixed heads are provided with the screw fixing with the casing lower end, and folded sheet one end is coupling with the connecting axle that is positioned at the fixed head middle part, and the folded sheet other end is coupling by universal drive shaft and wheel.Described folded sheet is positioned at the fixed head lower end.The width of described folded sheet is less than the width of fixed head.The threaded portion is established in the upper end of described universal drive shaft, and universal drive shaft is fixed in the corresponding screwed hole of folded sheet by the threaded portion.The said structure design has realized the purpose of this utility model.
The utility model makes the castor of case and bag or casing collapsible, have simple in structure, reasonable in design, folding and easy to use, the advantage that result of use is good.Concrete advantage is as follows:
1, carry walking when using case and bag daily, folded sheet opens, and this moment, wheel leant out outside casing, had enlarged the chassis strong point of casing, made the center of gravity of case and bag firm, can be not high because of center of gravity, the chassis is little topples over.
2, when container shipping, universal drive shaft can be unloaded, and take in the lump together with wheel and disintegrate lamination, then the folded sheet closure of turning back.Folded sheet is got back within casing takes up space, and can additionally not take transportation volume, and effect is especially obvious when the case and bag container shipping of multi-layer stacking.Also can simplify step during general transportation, not dismantle universal drive shaft and wheel, the folded sheet folding to vertical with fixed head, casing with the same horizontal of can falling fully of castor is not installed.
3, the utility model simple for structure, be easy to make processing, installation and use is convenient, and case and bag are advanced steadily, the volume when not increasing its container shipping again is specially adapted to the casing of erect type, flat, as qin box, instrumentation package box, suitcase etc.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of looking up of Fig. 1.
Fig. 3 is use status architecture schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of case and bag fold castor, mainly are comprised of fixed head 1 and wheel 5.Four jiaos of fixed heads are provided with the screw 6 fixing with the casing lower end, the lower-end corners of fixed head and case and bag or casing 7 can be fixed by screw.Folded sheet 3 one ends are coupling with the connecting axle 2 that is positioned at fixed head middle part, and the folded sheet other end is coupling by universal drive shaft 4 and wheel.
Described folded sheet is positioned at the fixed head lower end, and after opening folded sheet, folded sheet one side upper end holds in the fixed head lower end, is beneficial to load-bearing.The width of described folded sheet is less than the width of fixed head.The threaded portion is established in the upper end of described universal drive shaft, and universal drive shaft is fixed on by the threaded portion in the corresponding screwed hole of folded sheet, with convenient transportation, dismounting and installation.
In a word, the utility model makes the castor of case and bag or casing collapsible, has simple in structurely, reasonable in design, and folding and easy to use, the advantage that result of use is good can be promoted the use of.
