Progress along with current science and technology, the price of electronic product is more and more cheaper, become the object of mass consumption in the electronic product as PC, notebook computer, audio-visual products and domestic TV Game device etc., and in daily life and work, occupied very consequence.Regardless of different kinds of these electronic products, wherein all has electronic equipment, as PDA, PSP, NDSL, Wireless Pos 9603 etc.With wherein Wireless Pos 9603 is example, and this electronic product comprises upper casing and lower casing usually, and is fixed with screw.Owing to have the electronic product of this upper casing and lower casing when doing drop test, can be subjected to horizontal pulling force and shear action, and cause the screw in screw column (boss) hole of this lower casing to deviate from, even cause this boss hole to be broken, so that can't reach desirable requirement of strength.
Existing shell structure utilizes screw that this upper casing is fixed on the lower casing.Though, upper casing in this kind shell structure and lower casing are under the interference that does not have external force, also can firmly be fixed together, yet, because it is spacing that the standing part of this upper casing and this lower casing does not obtain, and can be subjected to the effect of pulling force and shearing force in test, and cause the constant intensity of this upper casing and lower casing to weaken, therefore can cause the breaking of boss hole of the boss hole of this upper casing and lower casing, so that can't reach desirable requirement of strength.
Therefore, how to overcome the shortcoming of aforementioned prior art, and propose in the process of upper and lower two shells combination, can reach the effect of better location and dispersive stress, increase the intensity of combination simultaneously, can also solve the improvement of this shell structure, become present industry the problem demanding urgently overcoming.
Summary of the invention
Be to solve the many disadvantages of aforementioned background art, the invention provides a kind of can be in the process of upper and lower shell combination location and dispersive stress and improve the shell structure of the bond strength of upper and lower two shells.
The invention provides a kind of fit location, can locate and the shell structure of the effect of dispersive stress.
Shell structure of the present invention, it is applied in the electronic equipment, and this electronic equipment has electronic component, and this shell structure comprises upper casing, lower casing, reaches first fastening part.This upper casing comprises retaining surface, is arranged at the fastener hole of these retaining surface central authorities and is arranged at this retaining surface fit portion on every side, and this electronic component is arranged in this upper casing; This lower casing comprises connecting portion, reaches second fastening part through this connecting portion, the connection sectional area of this connecting portion be slightly less than on this retaining surface not by this fit portion occupied fasten sectional area, second internal diameter of this second fastening part is equal to the fastening internal diameter of this fastener hole; This first fastening part comprises head and spiro union portion, an external diameter of this head is greater than this second internal diameter, the external diameter that is spirally connected of this spiro union portion equals this second internal diameter, and the length that is spirally connected of this spiro union portion is greater than the fastening length of this fastener hole even greater than the summation of second length of the fastening length of this fastener hole and this second fastening part.Thus, this first fastening part can be passed this fastener hole and prop up the mode of this retaining surface with this head by this spiro union portion, is anchored on this second fastening part, thereby makes the lower casing that is sleeved in this fit portion with this connecting portion be anchored on this upper casing.
Than existing shell structure, shell structure of the present invention is by being arranged at this upper casing fit portion cover on every side should the connecting portion of lower casing, with before this first fastening part is anchored on this second fastening part, being about to this upper casing earlier is positioned on this lower casing, so can increase the constant intensity between this upper casing and this lower casing.

Embodiment
Below by particular specific embodiment explanation embodiments of the present invention, those skilled in the art can understand other advantages of the present invention and effect easily by the content that this specification is set forth.The present invention also can be implemented or be used by other different specific embodiments, and each details in this specification also can be based on different viewpoints and application, carries out various modifications and change under the spirit of the present invention not deviating from.
See also Fig. 1, it is the side cutaway view of comparatively ideal embodiment middle shell structure 1 of the present invention, and shell structure 1 is applied in the electronic equipment, and this electronic equipment comprises electronic component.Shell structure 1 comprise first fastening part 11, upper casing 12, and lower casing 13, the first fastening parts 11 be used for upper casing 12 is anchored on the lower casing 13.
In comparatively ideal embodiment of the present invention, the connection sectional area of connecting portion 132 be slightly less than on the retaining surface 121 not by fit portion 120 occupied fasten sectional area, second internal diameter of second fastening part 131 is equal to the fastening internal diameter of fastener hole 122, an external diameter of the head 110 of first fastening part 11 is greater than this second internal diameter, the external diameter that is spirally connected of spiro union portion 111 equals this second internal diameter, and the length that is spirally connected of spiro union portion 111 is greater than the fastening length of fastener hole 122 even greater than the summation of second length of the fastening length of this fastener hole and this second fastening part.Thus, first fastening part 11 just can be passed fastener hole 122 and continue and prop up the mode of retaining surface 121 with head 110 by spiro union portion 111, be anchored in second fastening part 131, thereby make connecting portion 132 be sleeved on lower casing 13 in the fit portion 120, and then be anchored on upper casing 12.
