The specific embodiment
Technological means and the effect thereof taked for further setting forth the present invention are described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
See also Fig. 3 and Fig. 4, the present invention provides a kind of packing chest with removable shim, comprising: casing 2 and be installed on several pads 4 on the casing 2.These several pads 4 detachably are installed on the corner location of casing 2, and strengthening the support strength of this corner location, and then protection is loaded on the liquid-crystalline glasses panel (not shown) in the casing, avoids owing to external force causes the liquid-crystalline glasses panel breakage.
Said casing 2 comprises base plate 22 and is vertically connected at several side plates 24 of base plate 22 that said pad 4 is installed on the side plate 24.In the present embodiment, the quantity of this side plate 24 is four.
Said each pad 4 comprises body 42 and is connected in the installation portion 44 of body 42, and said side plate 24 corresponding installation portions 44 are provided with mounting groove 242, and this installation portion 44 is installed in the mounting groove 242, and then pad 4 is installed on the casing 2.
Said installation portion 44 comprises first installation unit 442 that is connected in body 42 and second installation unit 444 that is connected in first installation unit 442; The size of this second installation unit 444 is greater than the size of first installation unit 442; Said mounting groove 242 comprises first slot part 244 and second slot part 246 that is connected with first slot part 244; The size of this second slot part 246 is greater than the size of this first slot part 244; And then make second installation unit 444 be arranged in second slot part 246, realize the detachable installation of pad 4 and casing 2.
The base plate 22 and side plate 24 one-body molded the processing of said casing 2, preferred, said base plate 22 and side plate 24 are by expanded polypropylene (EPP) or one-body molded the processing of polyethylene foamed (EPE); The body 42 of said pad 4 and installation portion 44 one-body molded processing, preferred, said body 42 and installation portion 44 are by electrostatic prevention high density polyethylene foamed, ethylene-vinyl acetate copolymer (EVA) or one-body molded the processing of elastomeric material with electrostatic-proof function.Because side plate 24 all has elasticity with installation portion 44, this installation portion 44 can with mounting groove 242 interference fit of side plate 24, come off on the side plate 24 of casing 2 at transportation Intermediate gasket 4 preventing, and then can effectively protect the liquid-crystalline glasses panel.
The body 42 of said pad 4 is provided with at least one installation portion 44; Corresponding installation portion 44 is provided with at least one mounting groove 242 on the side plate 24 of said casing 2.
In the present embodiment, the installation portion 44 on said each pad 4 is two, and said second installation unit 444 cross sections are ball-type, and said mounting groove 242 corresponding each pad 4 are provided with two, and second slot part 246 corresponds to cylinder groove.Each installation portion 44 is arranged in respectively in the cooresponding mounting groove 242, and then pad 4 detachably is installed on the casing 2.
See also Fig. 5, for the present invention has the local structure scheme drawing of another embodiment of packing chest of removable shim, in the present embodiment; Installation portion 44 ' on said each pad 4 ' is two; Said second installation unit 444 ' cross section is trapezoidal, and its size increases towards first installation unit 442 gradually, and said second slot part 246 ' corresponds to dovetail groove; Its size increases towards first slot part 244 gradually, and it can realize the technique effect identical with first embodiment.
See also Fig. 6; The local structure scheme drawing that has the another embodiment of packing chest of removable shim for the present invention; In the present embodiment, said each pad 4 " on installation portion 44 " be one, and said second installation unit 444 " cross section is ball-type; said mounting groove 242 " corresponding each pad 4 " be provided with one, and second slot part 246 " correspond to cylinder groove.Each installation portion 44 " be arranged in cooresponding mounting groove 242 respectively " in, and then with pad 4 " detachably be installed on casing 2 " on, it can realize the technique effect identical with first embodiment.
In sum, the present invention has the packing chest of removable shim, and it cooperatively interacts through the mounting groove that on pad, is provided with in installation portion and the casing; Make pad and casing removably connect, simple to operate, and then promoted the assembling yield; And; Gasket construction is simple, and is reusable, and then reduced productive costs.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of claim of the present invention.
