Abstract
The utility model relates to a fixing screw structure for a heat radiator. A screw comprises a fastening pin, wherein the upper end of the fastening pin is provided with an end cap, the lower end of the fastening pin is in a conical shape, the middle of the fastening pin is provided with screw threads, an expansion sleeve is sheathed on the fastening pin through screw threads, a spring is sheathed on the expansion sleeve and the fastening pin, the inner diameter of the spring is smaller than the outer diameter of the end cap of the fastening pin, the inner side of the upper end of the expansion sleeve is provided with internal screw threads matched with the screw threads arranged in the middle of the fastening pin, the lower end of the expansion sleeve is provided with at least two opening sheets capable of being opened through being supported by the lower end of the fastening pin, and the outer surface of each opening sheet is provided with a convex clamping table. The fixing screw structure has the advantages that the design is ingenious, the fastening degree between the heat radiator and elements requiring the heat radiation is controlled through regulating the compression quantity of the spring, the stability of the installation position of the heat radiator can be ensured, the heat condition effect between the heat radiator and the elements requiring the heat radiation can be improved, meanwhile, the dismounting and the installation of the heat radiator are also very convenient, and the manufacture cost is low.
Description
Technical field
The utility model relates to a kind of improvement structure of fixing screw.
Background technique
Radiator is the important heat-dissipating parts of electric component such as computer, in order to guarantee its heat conduction, radiating effect, to its with higher by the installation requirement of heat-dissipating part, some is directly to adopt normal screws to fix for the installation of existing radiator, this mode of structure radiator is installed unstable, and heat-conducting effect and radiating effect are not good.Some is then fixed by the mechanism of complexity, though increase in performance aspect heat conduction and the heat radiation, the also corresponding increase of cost is installed also complicated.
The model utility content
In view of this, the technical problems to be solved in the utility model provides a kind of radiator set screw mechanism ingenious, that installation is stable that designs.
In order to solve the problems of the technologies described above, the utility model is realized in the following way:
A kind of radiator set screw structure, this screw comprise that a upper end has the fixed pin of end cap, and the fixed pin lower end is taper, the middle part is provided with screw thread, be with an expansion sleeve by screw thread on the fixed pin, be with a spring on expansion sleeve and fixed pin, this spring inside diameter is less than fixed pin end cap external diameter.
As improvement to such scheme, described expansion sleeve upper end is inboard to be provided with internal thread with the screw thread coupling at fixed pin middle part, the expansion sleeve lower end is provided with at least two can open sheet by what the fixed pin lower end strutted, opens the Ka Tai that the sheet outer surface is provided with projection.
The utility model design is ingenious, can be by the decrement control radiator of Regulation spring and by the fastening degree between radiating piece, can guarantee the stable of radiator mounting point, also can improve radiator and by the heat-conducting effect between the radiating piece, the dismounting of radiator simultaneously is also very convenient, and fabricating cost is low.
Description of drawings
Fig. 1 is the utility model embodiment overall structure schematic representation;
Fig. 2 is a present embodiment decomposing state structural representation;
Fig. 3 utilizes the screw of present embodiment that radiator is installed on structural representation on the radiating piece;
Fig. 4 is Fig. 3 decomposing state structural representation.
Embodiment
Defective at prior art exists describes in further detail of the present utility model for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing:
Shown in accompanying drawing 1,2, the radiator set screw structure that present embodiment discloses is made up of a fixed pin 1, expansion sleeve 2 and spring 3.Wherein, fixed pin 1 is a screw-like, and its upper end has end cap 11, and the middle part is provided with screw thread, and the lower end is taper.2 of expansion sleeves can be placed on the fixed pin 1, be provided with internal thread with the screw thread coupling at fixed pin 1 middle part in inboard, expansion sleeve 2 upper end, the lower end is provided with at least two can open sheet 21 by what fixed pin 1 lower end strutted, opens the card platform 22 that sheet 21 outer surfaces are provided with projection.3 on spring is placed on the expansion sleeve 2 of fixed pin 1 end cap 11 belows.
For another example shown in the accompanying drawing 3,4.In the time of on needs are installed on radiator 4 by radiating piece 5, at first expansion sleeve 2 and spring 3 are placed on the fixed pin 1, then expansion sleeve 2 are interted by in the default hole of radiator 3, this hole internal diameter greater than expansion sleeve 2 external diameters less than spring 3 external diameters.The sheet 21 that opens with expansion sleeve 2 lower ends interts by in the fixed hole default on the radiating piece 5 then, this fixed hole internal diameter then greater than the external diameter that opens sheet 21 original states less than opening sheet 21 by the external diameter after strutting.Tighten fixed pin 1 downwards, make the tapering part of fixed pin 1 lower end go deep into opening in the sheet 21 of expansion sleeve 2, opening sheet 21 opens laterally, and the card platform 22 that opens sheet 21 outer surfaces is stuck in by in the fixed hole of radiating piece 5, cooperating of platform 22 radiator 4 is fixed in by on the radiating piece 5 by spring 3 lower ends with card.Simultaneously, by turning fixed pin 1, adjustable springs 3 decrements, thus adjust radiator 4 with by the degree that is fastened of radiating piece 5.
Above embodiment only is the preferable implementation of the utility model; can not limit protection domain of the present utility model with this; under the present utility model design prerequisite that do not come off; still may have the distortion that belongs within the utility model protection domain, so similar conspicuous variation all belongs to protection domain of the present utility model.
