Specific implementation mode

The utility model is described in detail below with reference to embodiment shown in the drawings.But the embodiment is not Limit the utility model, structure that those skilled in the art are made according to the embodiment, method or functionally Transformation is all contained in the scope of protection of the utility model.The description of "front", "rear", "upper", "lower", which please refers to, to be illustrated as marking It is accurate.

It please refers to Fig.1 as the structural schematic diagram of packing box 100 provided by the utility model.The packing box 100 includes Inner box 1, outer box 2 and the retaining mechanism being set between inner box 1 and outer box 2, the outer box 2 are along the front end of first direction in opening Setting, so that the inner box 1 can pull out or be contained in backward in the outer box 2 from the outer box 2 along the first direction Portion.

In conjunction with shown in Fig. 2 to Fig. 4, both side plate 12, connection both side plate 12 that the inner box 1 has bottom plate 11, is oppositely arranged Foreboard 13 and back plate 14, what the bottom plate 11, side plate 12, foreboard 13 and back plate 14 were collectively formed upper opening holds space. The outer box 2 have side wall 23, the rear wall 24 of bottom wall 21, roof 22, the connection roof 22 and bottom wall 21.The retaining mechanism Including being fixed on the stop surface 32 for supporting plate 31, being formed in the bottom wall 21 of the bottom plate 11 and being set on the bottom wall 21 Control piece 33.When the inner box 1 is contained in completely in outer box 2, it is described support plate 31 be located at the rear side of stop surface 32 and with institute It states and abuts against before and after stop surface 32 to prevent the inner box 1 from being extracted out outward from outer box 2；When needs extract the inner box 1 out outward When, plate 31 is supported by 33 upward top pressure of the control piece so that the plate 31 that supports exceeds the stop surface 32 upwards, i.e., Inner box 1 can smoothly be extracted out.

The plate 31 that supports includes being attached at the fixed part 311 of 11 lower surface of the bottom plate and from the fixed part 311 The support division 312 that rear bends downward and extends towards top rake.The support division 312 extends beyond the fixed part 311 forward And it has the first elastic part 3121 between the fixed part 311 and bottom wall 21, from 3121 court of the first elastic part Before extend beyond the second elastic part 3122 of the fixed part 311.Second elastic part 3122 is transversely without departing from institute State the first elastic part 3121 and fixed part 311.

Usually, the control piece 33 is transversely set to the centre position of the bottom wall 21；The support division 312 is along cross Exceed the width of the control piece 33 transversely to the width of extension.The also two sides with front and back extension of the support division 312 3123 and what is be laterally extended support side 3124, when the control piece 33 compresses upwards, the middle section of the support division 312 is straight Capacity, and make in described support when the height of the part of 3124 adjacent sides 3123 can be slightly below described support 3124 Between part height, therefore, the junction setting arc angling 3125 for supporting side 3124 and side 3123, to avoid described Side 3124 and 3123 junction of side and 32 crimp of the stop surface are supported, the normal pull of inner box 1 is influenced.Preferably, The width of second elastic part 3122 transversely is less than the width of first elastic part 3121, the support division 312 At least side 3123 of side also 3123 ＇ of changeover portion with facing laterally inward retraction.

The bottom wall 21 includes substrate 211 and covers in the thickening layer 212 of 211 portion of upper surface of the substrate, the increasing The rear of thick-layer 212 forms the stop surface 32.Preferably, the equivalent width of the thickening layer 212 and the substrate 211, and The rear of the thickening layer 212 transversely linear extension.The control piece 33 and bottom wall 21 are in being wholely set and the control piece 33 are located in the substrate 211 of 212 rear side of the thickening layer, and the control piece 33 is preferably from second elastic part 3122 Lower section extends to the lower section of first elastic part 3121 backwards.

The width of the control piece 33 transversely gradually increased from after the previous dynasty, and the control piece 33 is preferably provided in semicircle Shape.The first breach 213 is formed between the control piece 33 and bottom wall 21.The bottom wall 21 is additionally provided with from the first breach 213 Rear end transversely extend outwardly the second breach 214, the third endwise and towards outer incline extended from the second breach 214 Breach 215.Second breach 214 and third breach 215 can reduce by 21 fatigue of materials of bottom wall, keep resilience；It can also subtract The stress of small 33 edge of the control piece especially rear end of first breach 213, avoids bottom wall 21 from tearing, thereby effectively prolongs The service life of the long packing box 100, improves structural reliability.

The inner box 1 further includes the pull for being arranged and extending beyond forward the foreboard 13 close to 11 upper surface of the bottom plate Plate 15.Adjacent to the part of the bottom plate 11 along the pull mouth 131 for laterally offering strip, the pull plate 15 has the foreboard 13 There is and runs through positioned at the main part 151 held in space and main body 151 pull of 131 projection facing forward of the pull mouth Portion 152.The front and rear edge of the main part 151 is respectively adjacent to or is connected to the foreboard 13 and back plate 14, to avoid the pull Portion 152 is held described in unexpected push in space, and causes pull inconvenient.Preferably, the size of the main part 151 and institute The size for stating bottom plate 11 is adapted, to hold the planarization of space bottom described in holding.

In conclusion using the utility model packing box 100, the stop surface 32 is held in by the plate 31 that supports, To prevent the inner box 1 from being skidded off outward from outer box 2；And plate 31 is supported so that described support by 33 upward top pressure of the control piece It holds plate 31 and exceeds the stop surface 32 upwards, in order to which inner box 1 is extracted out outward.100 structure of the packing box is more succinct durable, It is described to support plate 31 and 33 resilience performance of control piece is good, prolong the service life, is not easy to tear；And the packing box 100 is convenient for behaviour Make, there is preferable application foreground.

It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say As a whole, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can for bright book With the other embodiment of understanding.

Tool of the series of detailed descriptions listed above only for the feasible embodiment of the utility model Body illustrates that they are all without departing from made by the utility model skill spirit not to limit the scope of protection of the utility model Equivalent implementations or change should be included within the scope of protection of this utility model.
