Abstract
The utility model discloses a fastener, in particular to a screw used for connection of parts of computers, radiators and the like. The screw comprises a screw head and a screw rod, the screw head is provided with an installation groove, the screw rod is positioned at the lower end of the screw head, the upper portion of the screw rod is arranged into a thick screw rod, the lower portion of the screw rod is arranged into a thin screw rod, and the lower end of the thin screw rod is provided with a thread used for being connected with a connection hole of parts of the computers, radiators and the like. By means of the structure, the screw rod is arranged into a thick section and a thin section, rough positioning is firstly conducted through the lower-section thin screw rod, and the screw rod is screwed up after an installation is captured. As the thin screw rod is relatively thin, the installation position is easy to capture, installation time is saved, and installation efficiency is improved. An arranged annular groove can position two parts needing connecting, at the same time, only the thread of the lower section of the thin screw rod is turned, so that the screw rod is simple in processing technique, processing cost is low, and processing efficiency is high.
Description
Technical field
The utility model relates to a kind of fastening piece, specifically the screw used of the parts such as a kind of computer, radiator.
Background technique
The connected element that generally all needs that connection computer or radiator are used in the prior art is assembled; Because the parts more complicated of computer or cpu heat, the connected element that people adopt is generally long spiro nail, and screw of the prior art mostly is greatly a stock, be provided with screw thread on the stock, although adopt such structure can realize the connection of the parts such as computer, radiator, but there is following defective in such screw:
1, screw thread need to be with whole screw vehicle screw thread during machining screw through whole screw rod, and processing technology is complicated, wastes time and energy, and processing cost is high;
2, the equal diameters of whole screw rod is not easy to accurately find accurately link position when connecting the parts such as computer, radiator, caused inconvenience for the installation of computer, radiator etc., makes installation efficiency very low.
The model utility content
It is simple that the technical problems to be solved in the utility model provides the processing technology of a kind of not only screw own, and can conveniently connect the parts such as computer, radiator, improves the screw of installation efficiency.
In order to solve the problems of the technologies described above, screw of the present utility model, comprise with the screw head that groove is installed and the screw rod of screw head lower end, screw rod upper half part is set to thick screw rod, screw rod lower half portion is set to micro screw, and the lower end of micro screw is provided with the screw thread that is connected with the attachment hole of computer, heat sink assembly.
Also be provided with the annular groove that one section two-part that are used for computer, radiator to required connection positions on the described thick screw rod.
Described installation groove can also can be cross groove for the in-line groove.
The bottom of described screw thread is provided with the cone point of convenient location.
After adopting above-mentioned structure, because screw rod is set to two sections of thicknesses, can carry out first coarse localization by the micro screw of hypomere thus, again screw rod is screwed after finding the mounting point accurately, because micro screw is thinner so be easy to find accurately the mounting point, saved the installation time, installation efficiency is provided, the annular groove that arranges, can two-part that needs connect be positioned, owing to only the micro screw hypomere is carried out cutted thread, make thus the processing technology of screw rod simple simultaneously, processing cost is low, and work efficiency is high.

Fig. 2 is the plan structure schematic representation of the utility model screw.
Embodiment
Below in conjunction with the drawings and specific embodiments, screw of the present utility model is described in further detail.
As shown in the figure, screw of the present utility model comprises with in-line groove or cross the screw head 1 of groove 6 and the screw rod of screw head lower end is installed; Screw rod upper half part is set to thick screw rod 2, and screw rod lower half portion is set to micro screw 3, and wherein thick screw rod 2 is main body, plays main connection function, and micro screw 3 is slave part, plays the effect of auxiliary positioning; The lower end of micro screw 3 is provided with the screw thread 4 that is connected with the attachment hole of the parts such as computer, radiator, and the bottom of screw thread 4 is provided with the cone point 7 of convenient location, can be tightened by screw thread two-part with computer or radiator thus; Also be provided with the annular groove 5 that one section two-part that are used for the computer of required connection or radiator positions on the thick screw rod 2, can two-part that needs connect be positioned by annular groove 5.
Claims (4)
