Description

A kind of buckle connecting structure

Technical field

The utility model relates to mechanical manufacturing field, particularly relates to a kind of buckle connecting structure.

Background technology

At present, the drain pan of mobile phone mostly is metal structure, as shown in Figure 1, for a kind of structural representation of metal bottom shell, by utilizing CNC (Computernumericalcontrol, Digit Control Machine Tool) to make a deep gouge (groove) 201 at the side of metal bottom shell, as shown in Figure 2, this deep gouge 201 coordinates with the boss 401 (as shown in Figure 4) in the plastic surface shell (as shown in Figure 3) of interior of mobile phone, and the buckle realized between drain pan with face-piece is connected.Design sketch after the two assembling as shown in Figure 5.In Fig. 5,501 be metal bottom shell, 502 be deep gouge, 503 be boss, 504 for plastic surface shell.

But there are the following problems for above-mentioned buckle connecting structure:

1, because the buckle boss distortion on face-piece is almost nil, extrusion metal drain pan by force of need exerting oneself, makes flow of metal open outward, just can buckle into, there is the problem that plastic surface shell is difficult to buckle into metal bottom shell;

2, when machine is torn in production maintenance open, need to make metal bottom shell be out of shape energetically, face-piece just can disassemble, and easily causes metal card buckle side to subside, unrenewable, then causes inventory disposal, and cost improves;

3, firmly large owing to fastening, easily cause flow of metal excessive, after being assembled into complete machine, machine middle part is greater than two ends, causes product degree attractive in appearance and exquisite to decline;

4, production efficiency is low, and fasten the power needed with larger, operation employee production capacity is low, increases time cost.

Utility model content

The utility model provides a kind of buckle connecting structure, has that operating difficulties in dismounting and assembling process, housing are fragile, the exquisite appearance degree problems such as easily influenced and/or labor hour cost is large in order to solve buckle connecting structure in prior art between drain pan and face-piece.

Concrete, the buckle connecting structure that the utility model provides, comprise: drain pan and face-piece, described drain pan is provided with groove, described face-piece is provided with the boss that can be connected with described groove buckle, wherein, described boss is laid on elastic arm, allows the deformation space that described elastic arm is out of shape along pressure direction when the rear of described elastic arm is provided with pressing described boss.

Alternatively, in buckle connecting structure described in the utility model, described boss and described elastic arm integrated shaping.

Alternatively, in buckle connecting structure described in the utility model, described face-piece, boss and elastic arm are made by plastic material.

The utility model beneficial effect is as follows:

Buckle connecting structure described in the utility model improves coordinating of drain pan and face-piece, after guarantee assembling while terminal intensity, be convenient to produce line assembling operation (conveniently buckle into, solution is difficult to packing problem) and produce bad maintenance (be convenient to dismounting, after dismounting, material can reuse);

Buckle connecting structure described in the utility model can reduce inventory disposal, improving production efficiency and yield, thus reduces R&D costs;

Buckle connecting structure described in the utility model avoid metal bottom shell when assembling in the middle part of heave, ensure the exquisite degree of product.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of buckle connecting structure, is intended to the elastically deformable utilizing plastic cement, click-on design is become resilient arm structure, in mobile phone terminal assembling with when tearing machine open, and elastic arm elastically deformable, thus realize assembling smoothly and disassemble.

Concrete, buckle connecting structure described in the utility model, comprising: drain pan 610 and face-piece 620, and described drain pan 610 is provided with groove 611, and described face-piece 620 is provided with the boss 621 that can be connected with described groove 611 buckle, wherein:

Described boss 621 is laid on elastic arm 622, as shown in Figure 6, for boss 621 is laid in the structural representation on elastic arm 622.

The deformation space 630 that described elastic arm 622 is out of shape along pressure direction is allowed when the rear of described elastic arm 622 is provided with pressing described boss 621.In the present embodiment, it is front that elastic arm 622 arranges boss 621 side, and to arrange side be rear to the boss 621 that deviates from corresponded.And Fig. 6 is that oblique upper is the structure chart into visual angle in the past, so deformation space does not directly embody in figure.

Further, in a preferred embodiment of the present utility model, described boss 621 and the integrated molding structure of elastic arm 622.

Further, in another better enforcement of the present utility model, described face-piece 620, boss 621 and elastic arm 622 can be, but not limited to as being made up of plastic material.Described drain pan 610 can be, but not limited to as metal material is made.

In the utility model, face-piece 620 and the drain pan 610 of said structure are clasped as follows: as shown in Figure 7, when tearing machine open, utilize the strain of elastic arm, the elastic arm 622 of face-piece 620 is out of shape backward under machine of tearing open the pressure of drain pan 610, and utilizing the C angle of boss 621 to coordinate, boss 621 is extruded smoothly in the groove 611 of drain pan 610.As can be seen from above-mentioned engagement process, buckle connecting structure described in the utility model, due to the existence of elastic arm, facilitate buckling into and dismantling of drain pan, solve the problem of assembly and disassembly difficulty, and after dismounting, material not damaged can reuse, and avoids the problem of waste of material, avoid metal bottom shell assemble time in the middle part of heave, affect the problem of the exquisite degree of product.

It should be noted that, in the utility model, other portion structures of drain pan and face-piece are not protection directions of the present utility model, so, other structure divisions of the unspecified drain pan of the utility model and face-piece.

Although describe the application by embodiment, those skilled in the art will appreciate that the application has many distortion and change and do not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
