Abstract

The utility model discloses a splicing structure of a freezer case body, which is formed by splicing and encircling a front case board, a rear case board, a left case board and a right case board, inevery two adjacent spliced case boards, the edge of one of the case boards is bent into a folded edge, the edge of the other case board is bent into a U-shaped groove, the outer lateral edge of the formed U-shaped groove is bent outwards to form a fastening edge, an inserting slot is formed between the fastening edge and the outer lateral edge, and the folded edge is inserted in the inserting slot. The splicing structure has the advantages of reducing product cost, simplifying production procedures, increasing splicing efficiency, improving technical reasonableness of splicing process of the case boards and only needing to guarantee straightness (determined by forming molds) rather than guarantee parallelism or perpendicularity.

Description

A kind of splicing construction of refrigerator box body

Technical field

The utility model relates to a kind of refrigerator box body, and particularly a kind of splicing is the splicing construction of refrigerator box body easily.

Background technology

Refrigerator box body is to be spliced by the four blocks of boxboards in front, rear, left and right, and the connecting method of existing casing is as follows, earlier the left and right plate of refrigerator and forward and backward plate two ends splicing place is processed into U type limit 1, as shown in Figure 1; Again the U type limit 1 of the U type limit of the left and right plate of refrigerator and forward and backward plate is inserted between two U type limits 1 with the plastics cutting 2 of customization simultaneously and together then, as shown in Figure 2, two adjacent boxboards are fixed together, thereby boxboard splicing is all around surrounded refrigerator box body.

But said structure and connecting method have weak point, the first: the technological requirement height when the boxboard edges at two ends is processed into the U type, its depth of parallelism and linearity directly influence the presentation quality of refrigerator box body.It two is: the refrigerator boxboard adheres to as sprayed coating and can cause the thickening of U type limit on the U type limit after surperficial spray treatment, thereby plastics are transplanted a cutting and inserted not advance when splicing, and serious meeting is transplanted a cutting plastics to crack and caused the box body splicing failure.It three is: the casing of each refrigerator needs four plastics to transplant a cutting when splicing, so product cost just more increases by 2.0 yuan/platform.

Summary of the invention

The utility model has mainly solved above-mentioned deficiency of the prior art, provides a kind of making simple, and splicing is convenient, and the splicing construction of the refrigerator box body of escapable cost.

The technical solution of the utility model is achieved in that

A kind of splicing construction of refrigerator box body, be to surround by the four boxboard splicings in front, rear, left and right to form, in two blocks of boxboards of contiguous concatenation, wherein a boxboard edge is bent to form a flanging, the edge of another piece boxboard is bent to form a U type groove, the outer side edges that constitutes U type groove outwards is bent into one and buckles the limit, forms a slot between button limit and the outer side edges, and described flanging is plugged in the described slot.

In order to increase the grafting elastic force of slot, make the boxboard flanging insert behind the slot card and fasten admittedly, prevent to get loose, as preferably, the opening part width of described slot is narrower than its inner width.

As preferably, upper end, described button limit is bent to form a flange towards the direction away from the outer side edges of U type groove.Described flange plays a part guiding, makes the flanging of adjacent boxboard look for the position more convenient when inserting slot.

The beneficial effects of the utility model are:

A. reduce product cost, transplant a cutting owing to removed four plastics, so every refrigerator cost reduces by 2.0 yuan approximately.

B. simplify production process, splicing place of the left and right plate of the present invention only need be processed into the L type and be got final product, and promptly only need be bent into flanging and get final product, and is bent into the few procedure in U type limit than originally, and does not need slotting plastics cutting also to lack a procedure when splicing again, has improved splicing efficient.

C. improve the splicing place processing technology reasonability of boxboard, only need to guarantee that linearity (guaranteeing by mould) gets final product, and needn't impose its depth of parallelism or perpendicularity.

The specific embodiment

The specific embodiment of the present utility model is as follows:

Embodiment: as shown in Figure 3, Figure 4, a kind of splicing construction of refrigerator box body, be to surround by 3 splicings of the four blocks of boxboards in front, rear, left and right to form, in two blocks of boxboards of contiguous concatenation, with rearing-box plate 3a and right boxboard 3b is example, as Fig. 4, shown in Figure 6, the edge of wherein right boxboard 3b is bent to form a flanging 4, as Fig. 4, shown in Figure 5, the edge of rearing-box plate 3a is bent to form a U type groove 5, the outer side edges 6 that constitutes U type groove 5 outwards is bent into one and buckles limit 7, forms a slot 8 between button limit 7 and the outer side edges 6, and described flanging 4 is plugged in the described slot 8.

In order to increase the grafting elastic force of slot 8, make boxboard flanging 4 insert slot 8 back cards and fasten admittedly, to avoid getting loose, the opening part width of described slot 8 is narrower than its inner width.In addition, 7 upper ends, described button limit are bent to form a flange 9 towards the direction away from the outer side edges 6 of U type groove.Described flange 9 plays a part guiding, makes the flanging 4 of adjacent boxboard look for the position more convenient when inserting slot 8.

Claims
