Abstract
The utility model discloses a kind of ultra-thin accurate screw, comprise head, and the screw section to connect as one with described head, described head arranges cross recess, wherein, arrange four roads in described cross recess for increasing the raised line of friction, the thickness of described head is 0.15mm ~ 0.20mm, and the total length of described head and screw section is below 1.0mm.A kind of ultra-thin accurate screw that the utility model provides, fabrication cycle is fast, the lightening assembling of energy fit digital product, and cross recess Percent of contact area is good, and effectively promote client and produce line packaging efficiency, dimensional accuracy is high, can meet the requirement of client's high-quality.
Description
Technical field
The utility model relates to a kind of mechanical basic part, specifically relates to a kind of ultra-thin accurate screw.
Background technique
A kind of ultra-thin accurate screw that the utility model proposes is for lightening and high-quality demands of digital product such as current market notebook computer, panel computer and smart mobile phones, particularly propose for the smart mobile phone of below thickness 10mm and panel computer, specially for coordinating digital equipment production firm to design to the lightening of screw whole height, external diameter and head thickness and to the demand of precision screw.Screw traditional in prior art is because screw whole height, external diameter and head thickness can not meet assembling requirement, and screw tolerance of size is comparatively large, can not meet the requirement of client's high-quality.The utility model improves traditional screw for above-mentioned shortcoming.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of ultra-thin accurate screw, and screw is accurate, it is little to take up room, and fabrication cycle is fast, can coordinate the use of the product of different size, and especially can tackle digital product new product and release, flexibility is strong.
The utility model is for solving the problems of the technologies described above and providing a kind of ultra-thin accurate screw, its concrete structure comprises head, and the screw section to connect as one with described head, described head arranges cross recess, arranges four roads for increasing the raised line of friction in described cross recess.
Preferably, the thickness of described head is 0.15mm ~ 0.20mm.
Preferably, the shape of cross section of described raised line is rectangle.
Preferably, the both sides of described raised line are provided with and are respectively provided with a groove.
Preferably: the total length of described head and screw section is below 1.0mm.
The utility model has following beneficial effect relative to prior art: a kind of ultra-thin accurate screw that the utility model provides, by arranging four road raised lines in the cross recess of head, increase twisting resistance during screw assembling, stop the generation of distortion and skidding in screw assembling process, effectively can solve when client assembles and the phenomenons such as cross recess distortion, skidding occur, effectively improve the packaging efficiency of client, decrease the cost of production of client; In addition, screw is accurate, it is little to take up room, especially for such as producing the smart mobile phone of the digital product manufacturers, particularly below thickness 10mm such as notebook computer, panel computer and smart mobile phone and dull and stereotyped computer market; The product that the utility model provides also can do size adjusting according to customer demand, and the lightening assembling of energy fit digital product, cross recess Percent of contact area is good, and dimensional accuracy is high, can meet the requirement of client's high-quality.

In figure: 1, head; 2, cross recess; , 3 raised lines; 4, screw section
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
A kind of ultra-thin accurate screw that the utility model provides, comprises head 1, and the screw section 4 connected as one with described head 1, and described head 1 arranges cross recess 2, arranges four roads for increasing the raised line 3 of friction in described cross recess 2.In addition, the THICKNESS CONTROL of described head 1 is 0.15mm ~ 0.20mm, and described head 1 and the total length of screw section 4 control as below 1.0mm.
In order to make screw-driver avoid and screw generation relative movement when thread, the shape of cross section of raised line 3 is rectangle.
In order to increase the frictional force of screw-driver when thread, the both sides of raised line 3 are provided with and are respectively provided with a groove.
The product that the utility model provides is for lightening and high-quality demands of digital product such as notebook computer, panel computer and smart mobile phones on market, the particularly smart mobile phone of below thickness 10mm and the market demand of panel computer, effectively can overcome conventional screw because screw whole height, external diameter and head thickness can not meet assembling and the larger defect of screw tolerance of size.
The production cycle that the utility model provides is fast, flexibility is good, multi-size, can coordinate the use of the product of different size, and it is high that client produces dangerous packaging efficiency, screw is accurate, take up room little, fabrication cycle is short, within usual 3 ~ 7 days, can complete sample preparation, assembling property is good, has good anti-slip function.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
