The stacked plastic box in unit
Technical field
The utility model relates to a kind of Turnover Box, is specifically related to fixedly Turnover Box of the stacked plastics in a kind of unit.This Turnover Box is to make up stacked one-tenth with the cell cube of being made by two molds when producing, and reaches various height (also claiming the degree of depth) size with this.
Background technology
In wholesale, the retail process of commodity, need to use Turnover Box, so that the transportation of commodity, have enough to meet the need and deposit.Particularly in the pipelining, the frequency of utilization of Turnover Box is higher, is used for depositing semi-finished machinery, electronic product more in commercial production.
Divide from body structure, existing Turnover Box has two kinds of fixed type Turnover Box and folding turnaround cases.Collapsible during the folding turnaround case empty van, the storage volume is little, but its fastness is limited, only is suitable for depositing lighter article as electronic product etc.; The fixed type Turnover Box, casing is fixing not collapsible, but its fastness is good, can deposit the heavier article of deal, and Applicable scope is wider.
Existing fixed type Turnover Box is by lower shoe and four integrated uncovered square molding box bodies that sidewall constitutes, during production is to make mould by required size, with the mould integrated injection molding.Certainly, when the dimensions of product changes, die sinking tool in addition again, promptly can only produce a kind of product of length specification with a mold, therefore, manufacturer opens a series of mould according to the variation of various sizes at present, produces big and small a series of Turnover Box with this, to the high expense of the independent die sinking of each size Turnover Box, caused the high of Turnover Box productive costs.
On the other hand, when formulating the specification series of Turnover Box, except considering the variation of length and width two aspects, people must consider the variation of height, the very large a series of specifications of quantity have so just been extended, manufacturer must be at the independent die sinking production of the Turnover Box of all size, and die sinking quantity is big, and the fund input that Turnover Box is produced is huge.
Summary of the invention
The utility model purpose provides a kind of unit stacked plastic box, and purpose is the quantity of die sinking when reducing batch manufacturing with the stacked structure in unit, reduces the productive costs of Turnover Box.
For achieving the above object, the technical solution adopted in the utility model is: the stacked plastic box in a kind of unit, comprise that a base unit and at least one increase the unit, described base unit be by lower shoe and around around the one-body molded uncovered casing that constitutes of sidewall; Described each to increase the structure of unit identical, all be by around around the framework of the one-body molded upper and lower opening that constitutes of sidewall; The opening end of described bottom open end of increasing the unit and base unit is by captiveing joint to piecing together structure, and open top end of increasing the unit and another bottom open end of increasing the unit constitute the casing of differing heights by captiveing joint to piecing together structure with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " around sidewall all around " is meant barrel-contoured sidewall, it specifically can be the tubular that is made of polylith tabular sidewall, also can be directly constitute by the sidewall of a cylindrical tube shape, in other words, this just illustrates base unit and increases the box shape that the unit constitutes and do not limit, can be square, polygon or cylindrical.
2, in the such scheme, described " opening end of described bottom open end of increasing the unit and base unit is by captiveing joint to piecing together structure; and open top end of increasing the unit and another bottom open end of increasing the unit are by captiveing joint to the assembly structure; " captive joint wherein comprises various connection modes: clamping, welding or riveted joint etc., and to be connected and fixed reliably with base unit be an integral body in the unit as long as can will increase; Wherein the best is to adopt ultrasonic welding, and concrete mode is: establish the hot melt muscle between joint face, fix with ultrasonic welding then.
3, in the such scheme, described specifically have following two kinds of preferred version to piecing together structure:
The inboard on a, described bottom sides edge of increasing unit sidewall or lateral have the cross section and are " the connection side of " " shape; form an interface at the bottom opening place of increasing the unit with this; this interface embeds or is enclosed within on base unit uncovered; the cross section is for " connection side of " " shape and the sidewall of base unit lean, and at it between the two with welding or riveted and fixed, with this constitute increase between unit and the base unit to piecing together structure.Certainly, in order to realize many highly splicings with a plurality of unit of increasing, described open top of increasing the unit also will be complementary with the bottom interface of increasing the unit, it is increased the unit and increases as follows to piecing together structure between the unit: an interface of increasing unit bottom embed or be enclosed within last increase the unit open top in, " connection side of " " shape and increasing between the sidewall of unit leans; and between the two with welding or riveted and fixed, with this constitute increase the unit with increase between the unit to the assembly structure.
B, the described unit bottom edge of increasing are provided with a circle flanging laterally, base unit open-mouth edge also laterally correspondence be provided with one the circle flanging, the flanging of increasing the flanging of unit and base unit up and down against, and at it between the two with welding or riveted and fixed, with this constitute increase between unit and the base unit to piecing together structure.Certainly, in order to realize many highly splicings with a plurality of unit of increasing, the described top sides of unit of increasing is along also being provided with a circle flanging laterally, be complementary with the flanging of increasing the top, unit, it is increased the unit and increases as follows to piecing together structure between the unit: about a flanging of increasing unit bottom and the last flanging of increasing the top, unit against, its between the two with the welding or riveted and fixed, with this constitute increase the unit with increase between the unit to the assembly structure.
C, also can adopt simultaneously above two kinds to piecing together structure, that is: establish interface and at the bottom opening place of increasing the unit and enclose flanging, and the open-mouth of base unit and the top open part of increasing the unit are all established a circle flanging, both between flanging and flanging, be connected, " being connected between the connection side of " " shape and sidewall; fixing to piecing together structure, connecting fastness at interface again to improve with these two of constituting on vertical and horizontal two directions.
Design of the present utility model, principle of design are: adopt and to increase the mutually stacked structure of unit and base unit and make Turnover Box, produce a plurality of unit of increasing with a mold injection mo(u)lding during making, again with another set of mold injection molding production basis unit, then according to series specification, need not or to increase the unit mutually stacked with base unit to a plurality of with one respectively, produce the Turnover Box of a series of height dimensions, thereby reach as long as two molds can be produced the purpose of a series of height Turnover Boxes.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the special stacked structure in unit of the utility model as long as two molds can be produced the Turnover Box of series height, has reduced the required fund input amount of die sinking during production, greatly reduces the productive costs of Turnover Box.
2, because block construction of the present utility model is just fixing with ultrasonic welding when making, can guarantee its degree of being connected firmly, compare that its firmness, service life do not descend with integrated casing.
