Description
Technical field
The utility model is related to mounting technology field, more particularly to a kind of metal shell fixed structure.
Background technology
With the development of the electronic equipments such as mobile phone, computer, the material of the element of electronic device selection is presented diversification and becomes
Gesture, wherein due to metal material good heat dissipation effect, texture and appearance is good and the advantages such as intensity is high, the element of metal material
It is largely used in the electronic device.
A large amount of uses of metalwork relate to the connection between metalwork, and the connection type between existing metalwork is logical
There are three types of often：(1) connection between metalwork is realized by welding；(2) mode being screwed realizes metal
Connection between part；(3) connection being bonded by mucigel between realizing metalwork.
However, it is found by the inventors that at least there are the following problems in the prior art：(1) connection type welded so that two
It can not dismantle, make troubles for reprocessing for electronic equipment, and cause a degree of material waste between metalwork；(2) screw
Fixed mode so that nut exposes to appearance, affects the integrality of appearance, and the efficiency of assembling of screw is relatively low,
Appropriation of labour time is larger with manpower, to realize that the Automated assembly of screw, then higher to equipment requirement and cost are higher.
(3) in the fixed mode of mucigel, if adhesive strength causes greatly very much the dismounting between metalwork is more difficult (or to need other auxiliary
Mode is helped to dismantle, such as heating or solvent corrosion mucigel), if adhesive strength is weaker to lead between metalwork that connection can not
It leans on.

Second metal shell 12 is fixed or the complexity of dismounting；If the stiffness factor of elastic component 23 is smaller, the first metal shell
11 fix or remove opposite be easier to the second metal shell 12；If the stiffness factor of elastic component 23 is larger, first
Metal shell 11 is fixed or removes with the second metal shell 12 relatively harder.
In present embodiment, the number of elastic component 23 is related with the length of the first link block 21 (or second link block 22),
The number of elastic component 23 affects the first metal shell 11 and 12 fixation procedure of the second metal shell and metal-back in disassembly process
The moving equilibrium of body fixed structure.In one example, when the ratio of the length of the length and elastic component 23 of the first link block 21
When less than or equal to 3.5, an elastic component 23 may be used；If the ratio of the length of the first link block 21 and the length of elastic component 23
When more than 3.5, then multiple elastic components 23 are used, as shown in Figure 1, the number of elastic component 23 is 2；It is so exemplary theory here
It is bright, it is without being limited thereto in practice；The specific number of elastic component 23 can be set according to actual conditions.
In present embodiment, metal material may be used in the first link block 21 and the second link block 22, and intensity is high, the service life
Long, assembly is relatively reliable；So without being limited thereto in practice, the present embodiment is not intended to be limited in any the material of link block itself, such as
Link block can also use plastic material.
Preferably, in present embodiment, as shown in Fig. 2,4 and 5, the first link block 21 has the first stopper section 211, the
Two link blocks 22 have and 211 matched second stopper section 221 of the first stopper section；Second link block 22 is located at initial position
When, 221 backstop of the second stopper section is in the first stopper section 211；The second link block 22 is present embodiments provided movably to install
A kind of realization method in the first link block 21, it is so without being limited thereto in practice.
The utility model second embodiment is related to a kind of metal shell fixed structure, and second embodiment is implemented first
It is improved on the basis of mode, mainly thes improvement is that：As shown in Fig. 6 to 10, in the utility model second embodiment
In, the second link block 22 has the first inclined-plane 222 and the second inclined-plane 223.
In present embodiment, as shown in Figure 10, during the second metal shell 12 is connect with the first metal shell 11, the
Two metal shells 12 make elastic component 23 compress by oppressing the first inclined-plane 222, and the second gold medal is slid into so as to cause the second link block 22
In the resigning portion 121 for belonging to shell 12.
In present embodiment, during the second metal shell 12 and the dismounting of the first metal shell 11, the second metal shell
12 make elastic component 23 compress by oppressing the second inclined-plane 223, so as to cause the second link block 22 allowing from the second metal shell 12
It is skidded off in position portion 121.
In present embodiment, the first inclined-plane 222 of the second link block 22 and the range of grade on the second inclined-plane 223 be all higher than or
Equal to 45 degree and it is less than or equal to 60 degree；In the present embodiment, the first metal shell 11 and the second metal shell 12 are fixed and are dismantled
Complexity it is related with the gradient on inclined-plane, if the gradient on inclined-plane is smaller, the first metal shell 11 and the second metal shell 12
It is fixed to be relatively easy to removing, if the gradient on inclined-plane on the contrary is larger, the first metal shell 11 and the second metal shell 12
It fixes and removes more arduously.Present embodiment is not intended to be limited in any the specific value of slope on inclined-plane, can be according to practical feelings
Condition is specifically set.
In present embodiment, elastic component 23 includes spring or shrapnel；So without being limited thereto in practice, the present embodiment is to elastic component
23 concrete type is not intended to be limited in any.
