At present, cell phone rear cover on the market is provided with fixture block, and center is provided with corresponding with fixture block Draw-in groove, is linked together with center by the cooperation cell phone rear cover of fixture block and draw-in groove.Once cell phone rear cover On fixture block imprudence be broken off, then cell phone rear cover just becomes to be easy to come off on center.

Utility model content

This utility model is for the disappearance of prior art existence, it is provided that a kind of cell phone rear cover and the company of center Access node structure, makes bonnet more tight, firmly with the connection of center.

For achieving the above object, this utility model uses such as purgation technical scheme:

A kind of cell phone rear cover and the attachment structure of center, including bonnet and center, the both sides of described bonnet Being provided with the surrounding edge protruding from bonnet inner surface, the medial surface of described both sides surrounding edge is provided with draw-in groove, described Being provided with arc convex in draw-in groove, the upper end of described arc convex is higher than draw-in groove outer surface, described center Two sides be provided with the fixture block corresponding with draw-in groove, the surface of described fixture block is provided with corresponding with arc convex Arc groove, during assembling, center is stuck in the inner side of bonnet both sides coaming plate, and described fixture block is stuck in draw-in groove, Described arc convex is stuck in arc groove.

As a kind of preferred version, the draw-in groove mutual dislocation on the surrounding edge of described both sides is arranged.

This utility model compared with prior art, has the following advantages and advantage, specifically, passes through Draw-in groove and the arc convex of bonnet coordinate with fixture block and the arc groove of center, make bonnet tight with center Linking together, and on bonnet be draw-in groove, on center is fixture block, can avoid thus The situation causing bonnet to come off on center because fractureing fixture block occurs, so that bonnet and the company of center Connect more closely, firmly；The most such attachment structure makes center become simple with bonnet assembling, group Fill in hgher efficiency.

By more clearly illustrate architectural feature of the present utility model, technological means and reached concrete Purpose and function, come with specific embodiment to make this utility model the most below in conjunction with the accompanying drawings Bright:

Accompanying drawing explanation

Fig. 1 is the structural representation of the embodiment of this utility model；

Fig. 2 is the enlarged drawing in Fig. 1 at A；

Fig. 3 is the enlarged drawing in Fig. 1 at B.

Accompanying drawing identifier declaration:

1-bonnet, 2-center, 3-surrounding edge, 4-draw-in groove, 5-arc convex, 6-fixture block, 7-arc is recessed Groove.

Detailed description of the invention

As Figure 1-3, a kind of cell phone rear cover and the attachment structure of center, including bonnet 1 and center 2, The both sides of described bonnet 1 are provided with the surrounding edge 3 protruding from bonnet 1 inner surface, described both sides surrounding edge 3 interior Side is provided with draw-in groove 4, is provided with arc convex 5 in described draw-in groove 4, and the upper end of described arc convex 5 is higher than Draw-in groove 4 outer surface, the two sides of described center 2 are provided with the fixture block 6 corresponding with draw-in groove 4, described fixture block 6 Surface be provided with the arc groove 7 corresponding with arc convex 5, during assembling, center 2 is stuck in bonnet 1 both sides The inner side of coaming plate 3, described fixture block 6 is stuck in draw-in groove 4, and described arc convex 5 is stuck in arc groove 7. Draw-in groove 4 mutual dislocation on described both sides surrounding edge 3 is arranged.

In sum, this utility model is by the fixture block of the draw-in groove of bonnet and arc convex and center and arc Connected in star coordinates, and makes bonnet be closely joined together with center, and on bonnet is draw-in groove, center On be fixture block, the feelings causing bonnet to come off on center because fractureing fixture block can be avoided thus Condition occurs, so that bonnet is more tight, firmly with the connection of center；The most such attachment structure Making center assemble with bonnet and become simple, packaging efficiency is higher.

The above, be only preferred embodiment of the present utility model, not in order to limit this practicality Novel, thus every according to technology of the present utility model reality above example is made any amendment, Equivalent, improvement etc., all still fall within the range of technical solutions of the utility model.
