Abstract
A shell with meshing type rabbet structures is provided. The shell with the meshing type rabbet structures is characterized in that the shell comprises a first half shell and a second half shell; the periphery of the shell wall of the first half shell is alternately provided with recessed grooves and protruding edges so as to form one meshing type rabbet structure; the periphery of the shell wall of the second half shell is alternately provided with recessed grooves and protruding edges so as to form one meshing type rabbet structure, wherein the recessed grooves and the protruding edges of the second half shell are respectively corresponding to the protruding edges and the recessed grooves of the first half shell; and the two meshing type rabbet structures are meshed with each other, so that the first half shell and the second half shell can be connected together so as to form a complete shell. According to the shell with the meshing type rabbet structures of the utility model adopted, a single-rabbet and rib connection mode is replaced by a double-rabbet meshing structure connection mode, and therefore, side walls of the product can be perfectly aligned with each other, and deformation and dislocation under the effect of a thrust force can be avoided, and as a result, the two parts of the shell can be connected with each other more tightly, and inward and outward slide of the two parts of the shell can be avoided; and rib structures are omitted, so that the shell can be of structural simplicity, and inner space of the shell occupied by the ribs can be saved, and at the same time, manufacturing difficulty and cost can be reduced.
Description
Technical field
The utility model relates to housing, refers in particular to a kind of housing with engagement type fixing structure.
Background technology
Shell is the most general a kind of layer structure part, and it is widely used, in most of electronic product, be useful, and such as computer, mobile phone, portable hard drive etc., computer chassis, television cabin, hand set machine shell, instrument and meter casing motor case, micromachine casing etc.Can be divided into cabinet, alloy housing, composite material casing etc. according to material.
Shell comprises integral type shell and two-piece housing according to its connected mode, two-piece housing is generally to be dismantled and linked together by two parts shell, but, existing shell is the mode that adopts single seam+furcula (rib) while connecting design, that is: the periphery of two housing sections is equipped with a seam, the mutual interlock of two seams, be provided with furcula (rib) in the inside of lower half shell seam, to the seam of the seam of upper half shell and lower half shell is fixed, prevent that the housing assembling from misplacing under External Force Acting from outside to inside, loosening connection not fastening (prior art upper half shell as shown in Figure 1 and the assembling schematic diagram of lower half shell of causing, Fig. 2 to Fig. 5 is the concrete structure figure of each parts in Fig. 1), the problem that this mode exists comprises: a, after assembling the in the situation that of undercapacity or injection molding deformation, two parts of housing produce local shrinking away from theshell phenomenon, assemble insecure, b, increase furcula prevent inside or outside shrinking away from theshell degree in a side of seam between certain length, inner a lot of practical spaces but furcula can account for, reduce space in shell, c, adopt the mode complex structure of single seam+furcula (rib), cost is high.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of reasonable in design, in conjunction with fastening, saves the housing with engagement type fixing structure in enclosure interior space.
The technical scheme that the utility model is taked is as follows:
There is a housing for engagement type fixing structure, it is characterized in that comprising: the first half shells and the second half shells, wherein: the shell wall periphery of above-mentioned the first half shells is staggered is provided with groove and flange, forms engagement type fixing structure; The shell wall periphery of above-mentioned the second half shells is staggered groove and the flange of being provided with also, form engagement type fixing structure, and its groove and flange flange and the groove of corresponding the first half shells respectively, the mutual interlock of two engagement type fixing structures, the first half shells and the second half shells are linked together, form complete housing.
Preferably, described groove is identical with the thickness of flange, is the half of housing wall thickness, so that stressed even.
Preferably, described engagement type fixing structure is arranged on the whole periphery of the first half shells and the second half shell shell walls or on part periphery.
Preferably, described engagement type fixing structure comprises at least two grooves and at least two flanges, and groove and flange are crisscross arranged, and adjacent groove and flange lay respectively at inwall side and the outer wall side of housing.
The beneficial effects of the utility model are:
The utility model replaces with the mode of tradition list seam+furcula (rib) type of attachment of the engagement type structure of double stopper, can allow product sidewall complete matching, and ensure indeformablely under thrust not misplace being subject to, make two parts of housing connect more fastening, avoid both and inwardly or outwards slided, furcula structure has been removed, made shell structure simple, avoid furcula to take enclosure interior space, made manufacturing cost reduce simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Fig. 6 to Figure 11, a kind of housing with engagement type fixing structure, is characterized in that comprising: the first half shell A and the second half shell B, wherein: the shell wall periphery of above-mentioned the first half shell A is staggered is provided with groove and flange, forms engagement type fixing structure; The shell wall periphery of above-mentioned the second half shell B is staggered groove and the flange of being provided with also, form engagement type fixing structure, and its groove and flange be flange and the groove of corresponding the first half shell A respectively, the mutual interlock of two engagement type fixing structures, the first half shell A and the second half shell B are linked together, form complete housing.
