Description
Technical field:
The utility model relates to and a kind ofly holds the case and bag that article are used, but particularly relates to the case and bag that a kind of root need increase volume.
Background technology:
General case and bag such as draw-bar box, computer package, knapsack and travelling all be that the volume that limits is immutable with chest, and when user's article increase or minimizing, the volume of case and bag but can not increase and decrease.For this reason, someone adds an internal layer and is provided with slide fastener in the stage of case and bag, when needing increase-volume slide fastener is opened, draw back the purpose that internal layer has reached increase-volume, but the manufacturing procedure complexity of these class case and bag, materials cost height, the consumption that has particularly increased slide fastener increase the deadweight of case and bag itself, and folding and unfolding is cumbersome when using.
Summary of the invention:
The purpose of this utility model is exactly in order to overcome the shortcoming of prior art, designs a kind of case and bag of increased volume easy to use simple in structure.The utility model mainly comprises: casing, case lid, slide fastener and handle, it is characterized in that: be provided with a circle increase-volume portion between case lid and the casing, this increase-volume portion one has the banded stretchable layer of elastic force, one circle edge is connected with case lid, and the both sides of slide fastener are stitch-bonded to respectively on the limit mouth of banded stretchable layer another circle edge and casing of increase-volume portion.The banded stretchable layer of increase-volume portion and the inboard of case lid junction are provided with one deck waterproof cloth, this waterproof cloth one circle edge is connected with case lid with the banded stretchable layer one circle edge of increase-volume portion, and another circle edge sews up with slide fastener with another circle edge of banded stretchable layer of increase-volume portion.The utility model has the advantages that: simple and reliable for structure, the volume of case and bag can change within the specific limits with user's needs, during use flexible convenient freely, and can increase volume and not increase the deadweight of case and bag itself.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vertical view;
Fig. 3 is that the utility model structure waterproof cloth is provided with schematic diagram.
Among the figure: 1 case lid, 2 casings, 3 slide fasteners, 4 increase-volume portions, 5 handles.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
Embodiment one:
Be provided with a circle increase-volume portion 4 between one casing 2 and case lid 1 casing, this increase-volume portion 4 one has the banded stretchable layer 41 of elastic force, one circle edge is connected with case lid 1, two row zipper teeth both sides of slide fastener 3 are stitch-bonded to respectively on the limit mouth of another circle edges of increase-volume portion 4 banded stretchable layers 41 and casing 2, and handle 5 is located at the outside of casing 2.Hold article during use and only increase and need cover case lid 1, compress case lid 1 and casing 2 simultaneously and pull on and march 3, increase-volume portion 4 is extended with the article that increase, chest just can increase volume freely in the flexible scope of increase-volume portion 4.
Embodiment two:
Identical with embodiment one, different is: rain in order to prevent to use, but rainwater enters in the casing by the increase-volume portion 4 of stretching, one deck waterproof cloth 42 is established in inboard in described increase-volume portion 4 and case lid 1 junction, these waterproof cloth 42 1 circle edges are connected with case lid 1 with the banded stretchable layer 41 1 circle edges of increase-volume portion 4, and another circle edge sews up with slide fastener 3 with banded stretchable layer 41 another circle edges of increase-volume portion 4.This waterproof cloth 42 should be greater than the banded stretchable layer 41 of increase-volume portion 4, and size is identical during at least with banded stretchable layer 41 extended configurations of increase-volume portion 4, and influencing so that increase-volume portion 4 is not subjected to the tractive of waterproof cloth when flexible flexible should have scope.
