Description
本創作係關於一種固定裝置,特別是一種可提升彈簧壓縮行程的固定裝置。This creation relates to a fixture, in particular a fixture that increases the compression stroke of the spring.
請參考圖1,其係表示一種目前現有用以固定散熱裝置的固定裝置。如圖1所示,傳統的固定裝置1a包括有彈簧10a、螺絲20a及O型環40a。傳統的固定裝置1a為使彈簧10a能夠保持容置在固定柱91的容納空間911中,螺絲20a的螺桿22a部分會設有一圈凹槽(圖未示),藉以使O型環40a在由螺桿22a下方套設至於螺桿22a後,可藉由與凹槽的干涉來與螺桿22a連接固定。一旦O型環40a與螺桿22a連接固定以後,即可透過O型環40a來與固定柱91底端干涉,以防止彈簧10a及螺絲20a因劇烈晃動而脫離容納空間911。Please refer to FIG. 1 , which shows a conventional fixing device for fixing a heat sink. As shown in Fig. 1, the conventional fixing device 1a includes a spring 10a, a screw 20a, and an O-ring 40a. The conventional fixing device 1a is configured to enable the spring 10a to be received in the receiving space 911 of the fixing post 91. A portion of the screw 22a of the screw 20a is provided with a groove (not shown), so that the O-ring 40a is in the screw. The sleeve 22a is sleeved under the screw 22a and can be fixed to the screw 22a by interference with the groove. Once the O-ring 40a is connected and fixed to the screw 22a, the O-ring 40a can be interfered with the bottom end of the fixing post 91 to prevent the spring 10a and the screw 20a from being detached from the accommodating space 911 due to severe shaking.
雖然利用上述方法可有效防止彈簧10a掉落,但由於O型環40a係設置於固定柱91下方,因此導致螺桿22a原本突出於固定柱91底端的部分(即L1所示部分)長度變短了,連帶著也影響到了彈簧10a向下壓縮的距離,對於厚度空間有限的電子裝置,如超薄型筆記型電腦或平板電腦而言,此種固定裝置1a將不敷使用。Although the spring 10a can be effectively prevented from falling by the above method, since the O-ring 40a is disposed under the fixing post 91, the length of the portion of the screw 22a that originally protrudes from the bottom end of the fixing post 91 (i.e., the portion indicated by L1) becomes shorter. The connecting belt also affects the downward compression distance of the spring 10a. For an electronic device having a limited thickness space, such as an ultra-thin notebook computer or a tablet computer, such a fixing device 1a will not be used.
因此,實有必要發明一種新的固定裝置以解決前述問題。Therefore, it is necessary to invent a new fixture to solve the aforementioned problems.

The screw includes a screw head and a screw; the screw head has a main body and an interference ring, and the interference ring is disposed around the main body; the screw system is connected with the screw head, and the screw is located in the accommodating space through the top opening and the spring, and the screw is at least One part protrudes from the bottom opening. The fixed gasket ring is sleeved on the main body of the screw head and located on the interference ring, and the fixed gasket ring is connected to the top end of the fixing cylinder to seal the top opening to prevent the spring and the screw from coming off the receiving space.
依據本創作之一實施例,本創作之固定墊片環之外緣設有複數尖角,且複數尖角之角度均為銳角,藉以使固定墊片環透過該複數尖角以便與固定筒之頂端鉚合連接。According to an embodiment of the present invention, the outer edge of the fixed spacer ring of the present invention is provided with a plurality of sharp corners, and the angles of the plurality of sharp corners are all acute angles, so that the fixed gasket ring passes through the plurality of sharp corners to be fixed with the fixed cylinder Top riveted connection.

由於本創作構造新穎,能提供產業上利用,且確有增進功效,故依法申請新型專利。Because the creation of this creation is novel, it can provide industrial use, and it has improved efficiency, so it applies for a new patent according to law.
為讓本創作之上述和其他目的、特徵和優點能更明顯易懂,下文特舉出本創作之具體實施例,並配合所附圖式,作詳細說明如下。The above and other objects, features and advantages of the present invention will become more apparent and understood.
以下請一併參考圖2及圖3關於本創作之固定裝置之結構示意圖。Please refer to FIG. 2 and FIG. 3 for a schematic structural view of the fixing device of the present invention.
如圖2所示,於本創作之一實施例中,本創作之固定裝置1係用以將一散熱裝置90固定於一電路板(圖未示)上方,該散熱裝置90包括有複數固定筒91,各固定筒91之為一中空圓柱體,以於各固定筒91內部形成一容納空間911。複數固定筒91各具有一頂端912及底端913,其中頂端912設有頂部開口914,而底端913設有底部開口915;頂部開口914係與底部開口915上下相對應,且頂部開口914之截平面面積係大於底部開口915之截平面面積。於本創作之一實施例中,本創作之固定裝置1包括有彈簧10、螺絲20及固定墊片環30。As shown in FIG. 2, in one embodiment of the present invention, the fixture 1 of the present invention is used to fix a heat sink 90 to a circuit board (not shown). The heat sink 90 includes a plurality of fixed cylinders. 91. Each of the fixing cylinders 91 is a hollow cylinder, so that a receiving space 911 is formed inside each of the fixing cylinders 91. The plurality of fixing cylinders 91 each have a top end 912 and a bottom end 913, wherein the top end 912 is provided with a top opening 914, and the bottom end 913 is provided with a bottom opening 915; the top opening 914 is corresponding to the bottom opening 915, and the top opening 914 The sectional plane area is greater than the sectional plane area of the bottom opening 915. In one embodiment of the present invention, the fixture 1 of the present invention includes a spring 10, a screw 20, and a fixed gasket ring 30.
如圖2及圖3所示,彈簧10係設置於容納空間911中。As shown in FIGS. 2 and 3, the spring 10 is disposed in the accommodation space 911.
於本創作之一實施例中,螺絲20包括有螺絲頭21及螺桿22。螺絲頭21具有一主體211及干涉環212,干涉環212係環設於主體211周圍。螺桿22係與螺絲頭21相連接,其穿過固定筒91之頂部開口914及彈簧10而容置於容納空間911中,且螺桿22之至少一部分突出固定筒91之底部開口915。於本創作之一實施例中,螺桿22突出固定筒91之底部開口915之至少一部分的長度(即圖3所示L2)實質上為6.4毫米(mm),但本創作不以此為限。In one embodiment of the present invention, the screw 20 includes a screw head 21 and a screw 22. The screw head 21 has a main body 211 and an interference ring 212. The interference ring 212 is disposed around the main body 211. The screw 22 is coupled to the screw head 21, which is received in the accommodating space 911 through the top opening 914 of the fixed cylinder 91 and the spring 10, and at least a portion of the screw 22 protrudes from the bottom opening 915 of the fixed cylinder 91. In one embodiment of the present invention, the length of at least a portion of the bottom opening 915 of the screw 22 protruding from the fixed cylinder 91 (ie, L2 shown in FIG. 3) is substantially 6.4 millimeters (mm), but the present invention is not limited thereto.
於本創作之一實施例中,固定墊片環30套設至螺絲頭21之主體211並位於干涉環212之上方。固定墊片環30之外緣設有複數個尖角31,且每一尖角31之角度均為銳角。複數尖角31用以使固定墊片環30便於與固定筒91鉚 合連接,以使固定墊片環30可連接於固定筒91之頂端912,並密封頂部開口914,以防止彈簧10及螺桿22脫離容納空間911。In one embodiment of the present invention, the fixed shim ring 30 is sleeved to the body 211 of the screw head 21 and above the interference ring 212. The outer edge of the fixed spacer ring 30 is provided with a plurality of sharp corners 31, and the angle of each sharp corner 31 is an acute angle. The plurality of sharp corners 31 are used to facilitate the fixing of the gasket ring 30 with the fixing cylinder 91 The connection is such that the fixed gasket ring 30 can be coupled to the top end 912 of the fixed cylinder 91 and seal the top opening 914 to prevent the spring 10 and the screw 22 from disengaging from the receiving space 911.
如圖2及圖3所示,本創作之固定裝置1在與固定筒91完成結合後,可藉由固定墊片環30與干涉環212間的干涉,以防止彈簧10及螺桿22由頂部開口914脫離容納空間911。此外,由於彈簧10及螺絲頭21之截平面面積大於底部開口915的面積,因此也防止了彈簧10及螺桿22由底部開口915脫離容納空間911的可能。由於本創作之固定裝置1是利用固定墊片環30來達成固定的效果,且固定墊片環30係設置於固定筒91的頂端912,因此在組裝完成以後,固定墊片環30並不會影響到螺桿22突出於底部開口915之部分(即L2所示的部分)的長度,因而彈簧向下壓縮的行程距離也不會因此而受有影響,有效改善了先前技術之缺失。As shown in FIG. 2 and FIG. 3, after the fixing device 1 of the present invention is combined with the fixed cylinder 91, the interference between the spacer ring 30 and the interference ring 212 can be prevented to prevent the spring 10 and the screw 22 from opening from the top. The 914 is separated from the accommodation space 911. Further, since the sectional plane area of the spring 10 and the screw head 21 is larger than the area of the bottom opening 915, the possibility that the spring 10 and the screw 22 are separated from the accommodating space 911 by the bottom opening 915 is also prevented. Since the fixing device 1 of the present invention achieves the fixing effect by using the fixed spacer ring 30, and the fixed spacer ring 30 is disposed at the top end 912 of the fixed cylinder 91, the fixing of the spacer ring 30 does not occur after the assembly is completed. It affects the length of the portion of the screw 22 that protrudes from the bottom opening 915 (i.e., the portion shown by L2), and thus the stroke distance at which the spring is compressed downward is not affected thereby, effectively improving the lack of prior art.
綜上所陳,本創作無論就目的、手段及功效,在在均顯示其迥異於習知技術之特徵,懇請 貴審查委員明察,早日賜准專利,俾嘉惠社會,實感德便。惟應注意的是,上述諸多實施例僅係為了便於說明而舉例而已,本創作所主張之權利範圍自應以申請專利範圍所述為準,而非僅限於上述實施例。In summary, this creation, regardless of its purpose, means and efficacy, is showing its characteristics that are different from the well-known techniques. You are kindly requested to review the examination and express the patent as soon as possible. It is to be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the claims is intended to be limited by the scope of the claims.
