Description

A kind of case and bag casing with high tenacity

Technical field

The utility model belongs to case and bag technical field, is related to a kind of case and bag casing with high tenacity.

Background technology

As requirement of the people for daily living article is gradually lifted, the requirement for the crushing resistance and toughness of case and bag More and more higher, but in general casing is using extruding plastics sucking moulding, this results in the toughness of casing deficiency, in the mistake used Cheng Zhong, easily break, can cause forming process difficult during injection molding, while production process is more, long processing time.

It is most of only to select one case of band during going out to travel or going on a journey during the routine use of people Son, and during travelling process or aircraft are consigned, case and bag can often be fallen down, so in people for the toughness of casing It is required that also with regard to more and more higher, and two kinds of injection moldings of existing case and bag generally use, and then improve casing toughness Demand, although existing case and bag solve the problems, such as that casing toughness is poor in certain degree, due to the bearing capacity of plastics It is not strong, and then cause casing or easily produce the phenomenon of rupture.

The content of the invention

The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of case with high tenacity Lodge body, technical problem to be solved in the utility model are how to improve the toughness of casing.

The purpose of this utility model can be realized by following technical proposal：

A kind of case and bag casing with high tenacity, including outer layer, intermediate layer and internal layer, the intermediate layer be arranged on outer layer and Between internal layer, the outer layer and internal layer use PC or PET materials, it is characterised in that are convexed to form on the outer layer some Clamping block one, the intermediate layer are made of metal material, and some buckling grooves one, institute are offered on the lateral wall in the intermediate layer State that the lateral wall in intermediate layer is mutually binded with the inwall of outer layer and clamping block one can be embedded in corresponding buckling groove one, the internal layer Some clamping blocks two are convexed to form on lateral wall, some buckling grooves two, the centre are offered on the madial wall in the intermediate layer The madial wall of layer is mutually binded with the lateral wall of internal layer and clamping block two can be embedded in corresponding buckling groove two.

By using the structure of outer layer, intermediate layer and internal layer, the intensity increase to casing, while outer layer and internal layer are realized Adopt made of plastic, user can be caused to be not easy to scratch hand in use, and intermediate layer is to use the gold with high tenacity Category material be made so that when casing is by outer stressor layer, pressure is transferred to intermediate layer from outer layer, due to intermediate layer intensity and Good toughness, and then the most toughness for weakening the pressure from outer layer, improving casing of energy, buckling groove one and clamping block one Set, can make it that the connection between outer layer and intermediate layer is more firm, while when outer layer is squeezed and produces deformation, clamping Groove one can play a part of a resigning, the setting of buckling groove two and clamping block two so that the connection between internal layer and intermediate layer It is more firm, and then realize the raising of casing toughness.

In the above-mentioned case and bag casing with high tenacity, the clamping block one is dovetail-shape, and the buckling groove one is in swallow Tail shape, the side wall and the cell wall of buckling groove one of the clamping block one fit, and the clamping block two is dovetail-shape, the buckling groove Two is dovetail-shape, and the side wall and the cell wall of buckling groove two of the clamping block two fit.

Using the structure of swallow-tail form so that after mounting, outer layer and internal layer are further to improve all without departing from intermediate layer The stability of the structure of whole casing.

In the above-mentioned case and bag casing with high tenacity, the clamping block one and clamping block two are elongated.

In the above-mentioned case and bag casing with high tenacity, several resilient balls are provided between the outer layer and intermediate layer One, several resilient balls two are provided between the internal layer and intermediate layer.

The setting of resilient balls one and resilient balls two, outer layer is reduced to the extruding force in intermediate layer and intermediate layer to internal layer Extruding force.

In the above-mentioned case and bag casing with high tenacity, stiffener one, institute are convexed to form on the lateral wall of the outer layer State and stiffener two is convexed to form on the madial wall of internal layer, the length direction of the stiffener one and the length direction phase of clamping block one Together, the length direction of the stiffener two is identical with the length direction of clamping block two.

Compared with prior art, there is the case and bag casing of high tenacity to have the advantage that for this：Using outer layer and internal layer using modeling Expect material, intermediate layer uses the setting of metal material, further improves the toughness of casing.
