Description
Technical field
The utility model relates to the technical field of charger, in particular to a kind of multifunctional charger convenient for assembling.
Background technique
Charger is essential in the daily production of people as the matched portable charging apparatus of each class of electronic devices
Equipment.Charger case is as the protective device to internal circuit board and component, also essential a part of charger.
Existing charger case generally uses upper casing and lower casing to assemble, and is fixed by bolt.Upper casing with
For lower casing in order to can guarantee the closure effect between them, the opening of lower casing can generally be slightly larger than the opening of upper casing, in order to will be upper
Shell is tightly stuck on lower casing.However, this will lead to before carrying out bolt and fixing, lower casing is easy the problem of bouncing upper casing, therefore needs
It wants worker that upper casing is pressed on lower casing, influences, the packaging efficiency of charger case.
Utility model content
In view of the problems of the existing technology, the main purpose of the utility model is to provide a kind of convenient for the multi-functional of assembling
Charger improves the packaging efficiency of charger case.
To achieve the above object, the utility model proposes convenient for assembling multifunctional charger comprising upper casing, lower casing
And string holes.The upper casing opening edge portion is arranged with annular groove, and the lower casing opening edge portion is arranged with and the annular groove
Corresponding annular protrusion, the annular protrusion are connected in the annular groove.The edge side of the annular protrusion is equipped with positioning card
Bolt, the annular groove inside edge are equipped with fixed card slot corresponding with the positioning snib.
Preferably, the end of the positioning snib is in semicircle shape.
Preferably, the end of the positioning snib is equipped with ball bumps.
Preferably, the quantity of the positioning snib is two, and is arranged along the diagonal line of upper shell opener.
Preferably, it is obliquely installed on the outside of the upper end of the annular protrusion towards its medial surface.
The technical solution of the utility model is by being arranged positioning snib in the marginal portion of lower shell opener, in the opening of upper casing
Edge setting fixed card slot corresponding with positioning snib, contraposition is realized by positioning snib and fixed card slot and is fixed temporarily card
It connects, is bounced to avoid upper casing, subsequent screw is facilitated to fix, the packaging efficiency of charger case can be effectively improved.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the explosive view of an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of upper casing；
Fig. 3 is the assembling schematic diagram of upper casing and lower casing；
The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.
Specific embodiment
The utility model proposes a kind of multifunctional chargers convenient for assembling.
Referring to Fig.1-2, Fig. 1 is the explosive view of an embodiment of the present invention, and Fig. 2 is the structural schematic diagram of upper casing.
It as shown in Figs. 1-2, should be convenient for the multifunctional charger of assembling comprising upper casing in the utility model embodiment
100, lower casing 200 and string holes 300.100 opening edge portion of upper casing is arranged with annular groove 110, and 200 opening edge portion of lower casing sets up separately
There is annular protrusion 210 corresponding with annular groove 110, annular protrusion 210 is connected in annular groove 110.The edge of annular protrusion 210
Side is equipped with positioning snib 211, and 110 inside edge of annular groove is equipped with fixed card slot 111 corresponding with positioning snib 211.
In the present embodiment, the quantity for positioning snib 211 is two, and the diagonal line setting being open along lower casing 200.Diagonally
The positioning snib 211 of setting facilitates accurate contraposition, improves the packaging efficiency of upper casing 100 and lower casing 200.
The technical solution of the utility model is by being arranged positioning snib 211 in the marginal portion that lower casing 200 is open, in upper casing
100 open edge setting fixed card slot 111 corresponding with positioning snib 211, passes through positioning snib 211 and fixed card slot 111
Come realize contraposition and be fixed temporarily clamping, bounced to avoid upper casing 100, subsequent screw facilitated to fix, can effectively improved and fill
The packaging efficiency of electric appliance casing.
Preferably, in the present embodiment, it is obliquely installed on the outside of the upper end of annular protrusion 210 towards its medial surface, to be formed
Conical opening, convenient for annular protrusion 210 to be caught in annular groove 110.
Preferably, in the present embodiment, the end for positioning snib 211 is in semicircle shape, solid in order to position the insertion of snib 211
Determine in card slot 112.
Preferably, as shown in figure 3, in the present embodiment, the end of positioning snib 211 is equipped with ball bumps 112, corresponding
Ground.Spherical groove is set in fixed card slot 111.When positioning in the insertion locating groove 111 of snib 211, ball bumps 112 are pressed into ball
In shape slot, the fixed effect between positioning snib 211 and fixed card slot 111 is improved.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
