Abstract
The utility model discloses a framework structure of a luggage. The framework structure comprises an annular cover frame arranged at the outer rim of an opening of an upper luggage cover, and an annular bottom frame arranged at the outer rim of an opening of a lower luggage cover, wherein the cover frame or/and the bottom frame is/are integrated by a macromolecular material; at least one annular channel is formed in the cover frame or/and at least one annular channel is formed in the bottom frame; the annular channel is fully filled with inert gas. Compared with the prior art, the framework structure of the luggage, which is disclosed by the utility model, has the characteristics that (1) by the adoption of the macromolecular material for injection molding, the processing working procedures can be reduced, and connection opening deformation caused by a metal material is avoided; (2) the channels are filled with the inert gas, so that the use cost of the macromolecular material can be greatly reduced, and the phenomenon of shrinkage of the whole structure caused by the shrinkage of the macromolecular material can be avoided.
Description
Technical field
The utility model relates to case and bag, in particular, relates to a kind of frame structure of case and bag.
Background technology
Case and bag are one of people's daily living articles that often can use, and case and bag comprise upper box lid and lower case lid, realize the folding of casing between upper box lid and lower case lid by the frame structure of slide fastener or casing.Take frame structure as example, and it comprises cover frame and underframe, and the cover frame of annular is fixedly installed on the opening outer rim of upper box lid, and the underframe of annular is fixedly installed on the opening outer rim of lower case lid.During use, the connecting interface of the mutual coupling by cover frame outer end and underframe outer end is realized the closure of case and bag, very convenient.But existing annular cover frame and underframe generally adopt aluminium alloy extrusions bending to form, not only operation is many for whole like this process, also needs manual debugging, very complicated.And, due to the metallic character of aluminium alloy extrusions, also can cause connecting interface place easily to produce distortion, cause the well problem of closure of upper box lid and lower case lid.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of frame structure of case and bag.
For achieving the above object, the utility model adopts following technical scheme:
A frame structure for case and bag, the annular cover frame that comprises the opening outer rim of being located at upper box lid with and be located at the annular underframe of the opening outer rim of lower case lid,
Described cover frame, or/and underframe adopts macromolecular material one-body molded, is provided with at least one annular passage or/and be provided with at least one annular passage in described underframe in described cover frame; In described circular passage, be full of inert gas.
Described macromolecular material adopts with lower a kind of: ABS, PP and PC.
Described inert gas is nitrogen.
Compared with prior art, adopt the frame structure of a kind of case and bag of the present utility model to there is following characteristics:
1) adopt macromolecular material injection moulding integrated molding, can reduce manufacturing procedure, avoid adopting metal material and the interface distortion that causes;
2) adopt inert gas is set in passage, not only can significantly reduce the materials cost (about 30%-40%) of macromolecular material, but also can extend the phenomenon of the overall structure " shrink " that the retraction problems because of macromolecular material existence itself causes.
In a word, adopt the frame structure of the case and bag of utility model, the original aluminium frame of whole weight ratio wants light by 35% to 45%, and the original aluminium frame of strength ratio will increase by 45% to 55%.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the frame structure of a kind of case and bag of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, further illustrate the technical solution of the utility model.
Refer to the frame structure of a kind of case and bag shown in Fig. 1, the annular cover frame 11 that comprises the opening outer rim of being located at upper box lid (not shown) with and be located at the annular underframe 12 of the opening outer rim of lower case lid (not shown), cover frame 11 is or/and underframe 12 adopts macromolecular material one-body molded, in cover frame 11, be provided with the annular passage 13 that 2 opening outer rims along upper box lid arrange, in underframe, be provided with the annular passage 13 that 3 opening outer rims along lower case lid arrange; In circular passage, be full of inert gas.It should be noted that, the quantity of the passage of above-mentioned annular can and need according to the concrete shape of cover frame and underframe to change, and for example all right 1 can be also other quantity.
Macromolecular material for example can adopt with lower a kind of: ABS, PP and PC.
Preferably, inert gas is nitrogen.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the purpose of this utility model is described, and not with opposing restriction of the present utility model, as long as in essential scope of the present utility model, the variation of the above embodiment, modification all will be dropped in the scope of claim of the present utility model.
Claims (3)
1. a frame structure for case and bag, the annular cover frame that comprises the opening outer rim of being located at upper box lid with and be located at the annular underframe of the opening outer rim of lower case lid, it is characterized in that,
Described cover frame, or/and underframe adopts macromolecular material one-body molded, is provided with at least one annular passage or/and be provided with at least one annular passage in described underframe in described cover frame; In described circular passage, be full of inert gas.
2. the frame structure of case and bag according to claim 1, is characterized in that:
Described macromolecular material adopts with lower a kind of: ABS, PP and PC.
