The specific embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the utility model.
By among Fig. 1 as can be known, this Electron product packaging case with fluting board buffer pad comprises inner box 300, the outer box 200 of mutual fastening and is arranged at this inner box 300 and fastens the interior buffer pad 100 of institute's hollow region that forms with outer box 200, this buffer pad 100 is folded into 3D shape by a corrugated board, comprising the supply unit memory space 10 that separates after being folded by corrugated board, annex memory space 20 and product lay down area 30.The utility model adopts the folding liner buffer pad of corrugated board, can substitute traditional EPE and EPS material fully, and, structure design by exquisiteness, can also satisfy the requirement of test fully, meet national standard, adopt subregion to place each several part main frame and the accessory of product, preventing that it from wiping mutually bumps, and guarantees the intact of product.
By among Fig. 1 and Fig. 2 as can be known, supply unit of the present utility model memory space 10 comprise the first top board 12 with and dual-side extends and the first side plate 11 and second side plate 13 of in the same way bending.Product of the present utility model is be used to packing middle-size and small-size electronic product, the power unit volume of this series products is all larger, easily damage product main frame and other accessories, so, the utility model is carried out independent zoning for such accessory, and the space of reserving is also larger, can satisfy the requirement of the large volume accessories such as adapter fully.
By among Fig. 1 and Fig. 2 as can be known, annex of the present utility model memory space 20 comprises by the second side plate 13 another sides extends and the second top board 21 of outward and the 3rd side plate 22 of being believed bending by the side of the second top board 21, this its volume of class accessory is all smaller, and this class accessory generally all compares resistance to compression, so, the utility model with its be arranged on product below deposit, not only can reduce the volume of whole packing chest, effectively utilize the space, and, the impact resistance bottom can also increasing.
By among Fig. 1 and Fig. 2 as can be known, described product lay down area 30 comprises the first base plate 31 that the end by the second top board 21 extends out, extends folding the first side wall 32 and extend the second folding sidewall 33 along another side of the first base plate 31 along a side of the first base plate 31, and the hollow region of described the first base plate 31, the first side wall 32 and the second sidewall 33 formation of crowding around is shelved product.Described the first side wall 32 comprises the 4th side plate 321 that connects successively, the 3rd top board 322 and the 5th side plate 323, described the 4th side plate 321, the 3rd top board 322, the 5th side plate 323 and the first base plate 31 are crowded around into cylindrical sidewall, one side of described the 4th side plate 321 has two and is the first otch 324 that dovetail form is arranged, the position of described the second side plate 13 corresponding described the first otch 324 has second otch 131 identical with described the first otch 324 shapes, after product is folding, the folded cardboard creasing of the first otch 324 plays fixing effect to the breach the inside of the second otch 131.Described the second sidewall 33 comprises the 6th side plate 331, the 4th top board 332 and the heptalateral plate 333 that connects successively, and described the 6th side plate 331, the 4th top board 332, heptalateral plate 333 and the first base plate 31 are crowded around into cylindrical sidewall.Because a side of product lay down area 30 is Power Supply fittings, an other side is the outer wall of packing box, the impulsive force that both sides are subject to may be larger, so, the protection of both sides is extremely important, adopt cylindrical sidewall to carry out the side shield of product in the utility model, not only can strengthen the shock proof ability in side, and the sidewall of tubular can also improve the ability of its buffering, the support of multiple vertical direction, also can improve the up and down pressure resistance of both direction, so the design of this sidewall is extremely important, it also is emphasis of the present utility model place.
By among Fig. 1 and Fig. 2 as can be known, have two articles of three cutses 325 on the described the first side wall 32, these two articles of three cutses 325 extend to respectively on the 3rd top board 322 and the 5th side plate 323, after inwardly folding, these two articles of three cutses, 325 first folded flaps 326 form step-like depression, have two article of the 4th otch 334 on described the second sidewall 33, this two article of the 4th otch 334 extends to respectively on the 4th top board 332 and the heptalateral plate 333, forms step-like depression after these two article of the 4th otch, 334 second folded flaps 335 inwardly fold.The utility model is the buffering effect that further improves product, also adopted unsettled product to deposit scheme, product is shelved on the first flap 326 and the second flap 335 folding rear formation in the step-like depression, with wall all less than directly contacting, thereby guarantee when being subject to impacting have sufficient space to cushion.
By among Fig. 1 and Fig. 2 as can be known, for the structure that guarantees liner buffer pad in the utility model not loose, the side of the utility model the 5th side plate 323 free sides is extended with the first inserted sheet 327, the side of described heptalateral plate 333 free sides is extended with the second inserted sheet 336, the midway location of described the first base plate 31 has the jack 311 of two strip shapes, described the first inserted sheet 327 and the second inserted sheet 336 insert respectively in these two jacks 311, and the connection side of described the first base plate 31 and the second top board 21 is provided with the first connecting panel 312.And, after the first inserted sheet 327 and the second inserted sheet 336 insert jack 311, also protrude from the bottom surface of described the first base plate 31, directly be supported on the upper surface of the second top board 21, consist of longitudinally and support, further improve longitudinally pressure resistance.
By among Fig. 1 and Fig. 2 as can be known, the utility model is for guaranteeing the anti-bang ability of end face, product lay down area 30 of the present utility model also comprises the folding end retaining wall 34 of end limit extension by the first base plate 31, this end retaining wall 34 comprises the first end plate 341 that is extended and folded by the end limit of the first base plate 31 downwards, end plate by the first end plate 341 extends and the second folded-out base plate 342 and the second end plate 343 that is extended and made progress and fold by the end limit of the second base plate 342, also further comprises the first side plate 344 and the second side plate 345 that extend and inwardly fold along the second end plate 343 both sides respectively.End retaining wall 34 also adopts the structure of multidirectional folding grafting, and has reserved cushion space, thus, guarantees the impact resistance of end face direction, guarantees the safety of product.
By among Fig. 1 as can be known, for exhibiting product better, the position of corresponding described product lay down area 30 has transparent window 201 on described outer box 200 end faces, these transparent window 201 liner transparent plastic films 202.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
