The principle that the conventional raft cannot expand the turnover box: as shown in Fig. 18, the conventional raft structure described in the background art cannot be used to expand the turnover box. The conventional raft structure is that the hoe is in the sag, a group of 卯The 榫 structure has only one type of connection, and one type of connection has only one connection size. The one-turn container that can be expanded into a turnover box and the expansion into a plurality of units combined with the turnover box require the side panels to be assembled into different splicing lengths, so the conventional 卯榫 connection method has only one connection size and cannot use one side panel. The splicing into a unit turnover box can be spliced into multiple units to merge the turnover box.

The upper diagram of Fig. 18 is a splicing side panel 1 of the present invention, but the splicing side panel 1 is fully spliced with a conventional cymbal. \¥0 2019/119533 卩(:17 \2018/000419 榫 seamless and seamless connection, the connection length of the two splicing side panels 1 is less than the length of the two upper and lower covers 3 The length, using the splicing side panel 1 of the present invention but connected by a conventional raft, can not be connected to an extended turnover box, can only be connected to "2 _& = 2 + 3 〇 - (: /2", can not achieve the purpose of the invention, With the traditional 卯榫卯榫全卯榫卯榫 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,

As shown in the lower part of Fig. 18, the splicing side panel 1 of the present invention is used to splicing the turnover box, and the splicing side panel 1 is connected by a squeezing method with a slotted gap, and the raft is seamlessly leak-free. The empty full-fitting mode is combined and connected, and the two types of splicing side plates 1 can be connected into a "2& = 2 + 3 (;" length, which is exactly two upper and lower covers. The same plane connection length of the board 3, so with the splicing side panel 1 and the upper and lower cover 3 of the present invention, the two types of connection can be realized to expand into a large inner and inner turnover box by using two types of joints. The three principles of the ability to expand the tote are:

The first is to invent the long and short dual-purpose boring head and the deep and shallow dual-purpose grooving: The splicing side panel 1 卯榫 structure of the present invention can be connected into two kinds of length and length, and the splicing side panel 1 has two of the deep and shallow dual-purpose boring 10 The depth-to-depth concave rack 26 makes the deep and shallow dual-purpose groove 10 a deep and shallow dual-purpose groove which can be used with one concave rack 26 and two internal concave racks 26. The single-slip length of the splicing side panel 1 has two slanted racks 25 of equal length of the cross-section of the slats, so that the single-slip length of the dual-purpose slats 4 becomes available with an external rack 25 and is available Two outer convex racks 25 long and short dual-purpose purlins.

The second is to invent the matching of the size of each side of the splicing side panel 1, that is, the pitch-width relationship of each convex tooth: the same single-slip length and the length of the dual-purpose sill edge 4, one single-slip length and the length of the double-use slat edge 4 The width of the convex rack 25 is: 1 single sliding length and the length of the other convex rack 25 of the double-purpose purlining edge 4: the same side of the shallow-ditch dual-purpose slot 10, one side of the deep and shallow dual-purpose slot 10 Width of the concave rack 26: 1 width of the inner side of the two sides of the double groove 40: Width of the inner concave rack 26 of one end shallow groove 11 = 1 : 1 : 1 : 1 : 1〇 The engagement of the cymbal size causes a single spur rack 25 of the single-slip length dual-purpose slat edge 4 to be caught in one of the inner concave racks 26 of the side-deep-ditch sipe 10 to produce a short-sized connection; The two externally toothed racks 25 of the single-slip length and the double-striped side 4 are engaged in the two internal concave racks 26 of the side-deep-ditch dual-purpose groove 10 to produce a long-sized connection. This realizes that the splicing of the side panel 1 produces two long and short connection sizes, which solves the conventional splicing method, which has only one connection size and cannot be spliced into one unit by one side panel. The tote box can be spliced into a plurality of units to merge the totes.

The third is to invent the position setting of each side of the splicing side panel 1: the single sliding length and the short slat edge 4 and the single sliding double sill edge 5 are on opposite sides of the splicing side panel 1. Among them, the single-slip length and the short-sleeve side 4 are on one side of the end face, which can be used for extending and connecting the corners. It is a corner and an extended dual-purpose purlin; the single-slip double-slot edge 5 is a shallow and shallow dual-purpose gutter 10 The inner surface 9 of the splicing side panel 1 is only used for the corner, and the shallow grooving groove 11 of the single-sliding double sipe edge 5 is on the end surface of the splicing side panel 1 and is only used for extending the length when expanding; splicing the sipe of the side panel 1 Divided into a shallow and shallow dual purpose slot 10 for corners, and shallow for expansion \¥0 2019/119533 卩(:17 \2018/000419 slot 11.

The fourth is to invent an extended volume connection method of the structural splicing side panel 1: As shown in Fig. 12, when splicing a unit of the tote box, one splicing side panel 1 only uses a single sliding length and a short slat edge 4 and another piece The shallow and double gutters 10 of the splicing side plate 1 are connected in a full and seamless manner. As shown in Fig. 13, when the turnover box is extended, the single-slip length of the first piece of the splicing side plate 1 and the two-slice sipe 10 of the second piece of the splicing side plate 1 have (;/2 slit corners) In the manner of connection, the shallow groove 11 of the third splicing side panel 1 is connected with one of the single slat lengths of the first splicing side panel 1 of the first splicing side panel 1. The specific multi-splicing side panel 1 The description of the expansion of the connection to the extended upper and lower cover 3 is as follows: As shown in Fig. 13, when the tote is extended, the side plate 1 is spliced at the corner position [used on the grid line]. An externally toothed rack 25 of the strip edge 4 is snapped into an inner concave rack 26 of the shallow and shallow dual purpose slot 10, leaving a depth of 〇/2 in the shallow and shallow dual purpose slot 10, which is fully engaged with respect to FIG. In other words, the splicing side panel 1 corresponding to the corner position [used on the grid line] has a 〇/2 length; the splicing side panel 1 for extension [no grid line representation] single-slip length dual-purpose slat edge 4 Only one convex rack 25 is snapped into an inner concave rack 26 of the shallow groove 11, and the splicing side plate 1 for extension [the gridless line table ] Single sliding length dual-purpose purlin edge 4 Another external convex rack 25 is not in the gutter. Compared with the full entrapment of Fig. 12, the splicing side panel 1 for extension [no grid line representation] is added. /2 length. Thus, as shown in Fig. 13, in the extended connection mode, the corner position [used in the grid line] is extended by the splicing side panel 1 [no grid line representation] is added (: /2 length, for extension) The splicing side panel 1 [no grid line representation] adds 〇/2 length. Compared with the full card of Fig. 12, the corner of the same plane and the two splicing side panels 1 for extension have a total length, which is equivalent to The thickness of the splicing side panel 1 is increased, that is, when the two units of FIG. 12 are spliced, two splicing side panels 1 are overlapped in the middle, so that the splicing side panel 1 of FIG. 13 can be combined with the two upper and lower panels 3 The total length is equal. Figure 13 expands the square formed by the 8 splicing side panels 1 and the total length of the squares of the four upper and lower covers 3 are exactly equal, and the square of the splicing side panels 1 of the expansion mode can be realized. Connected to the four upper and lower covers 3 of the expansion mode to form a square connection into a turnover Box.

As shown in Figure 13, when expanding the tote,

The total length of _{a top} and bottom cover 3 _a = [b + c + 〇 / 2] = corner transfer [used on the grid line] splicing the total length of the side panel 1;

One upper and lower cover 3

Extend the [no grid line representation] to splicing the total length of the side panel 1;

The total length of one side of the 4 upper and lower covers 3 of 2x2 is 23 = 2 x^ + 0 + 0/2] =

Corner position [used on grid lines] splicing side panel 1 total length + extension [no grid line representation] splicing side panel 1 total length. Only the upper and lower cover plates 3 and the splicing side plates 1 can be used to realize the expansion of the expansion box of 2 x 2 upper and lower cover plates 3 . A unit turnover box splicing method, as shown in Fig. 12, in a 4 piece splicing side plate 1 and 2 upper and lower cover plates 3 into a single 0 2019/119533 ?<:17 52018/000419 When the box is turned, the single-slip length and the short-striped side 4 of the end face of one piece of the splicing side plate 1 are all inserted into the side of the other side of the splicing side plate 1 There is no hole space in the side-deep-sand dual-purpose gutter 10, that is, the two outer convex racks 25 of the single-slip length and the double-purpose purlins edge 4 are fully fitted with the two concave-concave racks 26 of the side-deep-dark dual-purpose gutter 10 There is no hole space.

Unit turnover box upper and lower cover 3 length splicing side panel 1 main body length + splicing side panel 1 single sliding length and width of dual purpose sill edge 4 (: + splicing side panel 1 shallow sipe 11 depth <: /2, ie 3 = +〇+(:/2. Two stitching side panels 1 two corner stitching methods are as follows: Figure 12, the first one unit turnover box corner stitching method is, the first stitching side panel 1 single sliding length The two externally protruding racks 25 of the dual-purpose rafter edge 4 are all snapped into the deep and shallow dual-purpose groove 10 of the second splicing side panel 1, and the deep and shallow dual-purpose grooving 10 does not leave a hole. The corner splicing method of the extended turnover box is that the first splicing side plate 1 has two single convex racks 25 of the single slat length and the short slat side 4, and only one outer convex rack 25 and the second one can be used. The inner side of the block splicing side plate 1 is fully fitted with a concave rack 26 on the outer side of the sipe 10 to realize the corner splicing. The side slanting and shallowing groove 10 at the corner has a hole space, and the hole space depth is (: /2, equivalent to the first piece of the splicing side plate 1 added in the structure of the (: /2 length. Methods as below:

The method for the same plane extension splicing of the two splicing side panels 1 is: when the first splicing side panel 1 of the 〇/2 length is added and the same plane is extended, the first splicing side panel 1 of the 〇/2 length is added. The end shallow groove 11 has a depth of only 〇/2, and the third piece of the same side of the splicing side plate 1 for the same plane extension has only one of the two outer ribs That one of the convex racks 25 is caught in the shallow groove 11 of the first splicing side panel 1. In the single-slip length and short-strip side 4 of the third splicing side panel 1, the outer convex rack 25 is not able to be caught in the shallow grooving groove 11. The outer convex rack 25 has a length of 〇/2, and the outer convex rack 25 of the third splicing side panel 1 is similar to the plane extension of the first block and the third splicing side panel 1. The third splicing side panel 1 is further extended by 0/2. 2x2 four upper and lower cover plates 3 are combined into four unit turnover boxes with a length of 2 _& each side, as shown in Figure 13, the first piece of the connected piece and the third piece of the side plate 1 are added with two corners to join the side plate 1 The length is also 2&, as follows:

2& = 2 + 3〇=^ +〇+(:/2] of the first side panel + ^ +〇+(:/2] of the third side panel = two upper and lower covers of the extension phase Sum.

It can be seen that the splicing side plate 1 and the upper and lower cover plates 3 used for splicing the unit turnover box of FIG. 12 can also be used for assembling the four-unit upper and lower cover plates 3 of FIG. 13 into four units and expanding the turnover box. That is, the splicing side panel 1 and the upper and lower slabs 3 of the present invention are a unit splicing box of the unit turnover box and the above-mentioned person, : 6, (:, 0, £, etc., some splicing structures, vacant capacity expansion turnover boxes. The set of corresponding sides of the upper and lower cover plates 3 constituting the tote is a plug-and-slide two-way connecting structural component \¥0 2019/119533 卩 (: 17 \2018/000419 set side 38, another set of corresponding sides is a single plug-in connection structure set side 39;

Each of the inserting and sliding two-way connecting structural members is provided with a side surface of the side 38 and a spherical missing card sliding protrusion 17 and a sliding type short groove 18 on different sides, but the number and position correspond; each single insertion The ball-shaped snap-slip projections 17, the snap-slip type sipe 18, and the porous communication sipe 37 of the side and end faces of the side of the connecting member 39 are disposed on different faces, but in number and position. The expansion of the present invention means that the turnover box is composed of four splicing side plates 1 and two upper and lower cover plates 3, and after expanding into an extended turnover box of a plurality of unit turnover boxes, the inner space of the expansion turnover box is not separated. Board, the inner space of the extended tote is the consolidation space of multiple unit turnover boxes. Expansion of the tote is also called a consolidation of the tote or an extended tote.
