The specific embodiment
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1-2, the laborsaving leather trunk of the utility model volute spring formula, comprises pull bar 1, upper school bag 2, lower box 3, handle 4, wheel 5, volute spring 6, support wheel 7, backpack strip 8, universal wheel 9, pull bar 2 10, side supporter 11.
The laborsaving leather trunk course of work of volute spring formula: be provided with hard interlayer in casing 3, in order to fill not to be stowed under heavy cargo breakables; Casing 3 is detachable, and detachable casing junior unit interconnects with slide fastener, with fabric sleeve and the pull bar at back, is connected and fixed, and while placing leather trunk when hoisting like this, can first split into two parts again to exceeding placement; Four universal rolls 9 and takes turns space 90o and be connected with centre wheel 5, centre wheel 5 is connected with center rod, the volute spring 6 with energy storage effect is housed at center rod place, can storage power downstairs time, during upstairs, energy discharges and can make stairs, adds a support wheel 7 in leather trunk bottom simultaneously, and downstairs time, support wheel 7 can play a supportive role, impulsive force when reducing leather trunk simultaneously and moving downward is milder while making downstairs; Determine the space size that you need, casing 3 is split into the form that you need, the article that then classification will be loaded and transported are put in casing 3, and for example frangible article can be put into hard interlayer, pack complete, can transport; When running into stair climbing, wheel 5 can reach by the energy storage of volute spring 6 labour-saving object, and pull bar is comprised of pull bar 1 and pull bar 22, uses flexibly, and upper school bag 2 detachably gets off, easy to use.
Preferably, described volute spring is contained on the axle that wheel is connected with casing, and four universal wheels are distributed on the wheel body of described wheel, and pull bar is comprised of pull bar one and pull bar two, and pull bar, adding a hinge and handle near handle portion, can make pull bar flexible like this.
Preferably, described support wheel in distribution triangular in shape, has increased stability when leather trunk is vertical with wheel, and side supporter is consistent with wheel height, is used for supporting box while being sidelong.
Preferably, volute spring and the universal wheel of the energy storage effect that this described scheme adopts cooperatively interact, and play power-saving function, while particularly above going downstairs, by the cooperation of the two, can pull on stair completely.
Preferably, in described casing, be provided with hard interlayer, be used for filling breakables, casing is detachable, and detachable casing junior unit interconnects with slide fastener, with fabric sleeve and the pull bar at back, is connected and fixed, while placing leather trunk when hoisting like this, can first split into two parts again to exceeding placement.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
