    松不脫螺釘
    瀏覽: 發布日期:2018-09-10


    廣州晟峰五金生產各種應用于面板上的螺釘:松不脫螺釘,也叫彈簧螺絲。松不脫螺釘可鉚接于鐵板上能自由擰進擰出螺絲,原理見本頁下附的動畫過程,該整體件能牢牢的鑲在面板上不脫離面板,故也稱不脫出螺釘。其外圓的手擰套一般都壓有直紋的齒,以便于手擰或手動擰緊,同時它也叫手緊螺釘或手擰螺釘。

    松不脫面板螺釘(彈簧螺釘)可用于安裝PCB板,只占微小空間。手緊螺釘的壓鉚套具有壓花齒,壓裝于于機箱或薄鈑孔內(注:薄板的鉆孔徑相對應彈簧螺釘的壓齒徑有一定要求的,請參考以下各明的技術參數),形成一個外露的彈簧螺釘,用手擰另一端(即手擰端).因其里面固定有彈簧,螺釘相對于薄板的另一端來回進出。該方案解決了需要經常拆卸螺釘難題,而且非常方便實用。

    可以查看松不脫螺釘安裝于面板后的效果圖

    當然,除了上述的幾種標準品外我公司還生產各種奇形怪狀的松不脫螺絲,可以根據用戶要求生產如同這些示例非標松不脫螺釘

    下面為標準PF11/PF12松不脫螺釘的示例/圖片/圖紙/技術參考介紹:

    松不脫螺釘

    名稱:松不脫螺釘,面板螺釘,彈簧手緊螺釘
    左圖小規格的松不螺釘規格為PF11 M3-0, 大的規格為M5-1 
    材質:碳鋼螺釘,碳鋼壓鉚套,鋁手擰套之組合;不銹鋼螺釘,不銹鋼壓鉚套,鋁手擰套之組合
    廣州晟峰五金生產的不脫出面板螺釘,質量一流,除了彈簧外協配套外,其余部件全部由本公司自行生產組裝完成,品質嚴格把關,相對于進口的松不脫螺釘而方具有很高的性價比,且其質量完全具有可替代性。
    彈簧螺釘
    左為PF11 M6-2松不脫螺釘.
    面板彈簧螺釘(松不脫螺釘)的構成分成幾個組成部分:
    1,螺釘部分( 緊固機箱薄板的另一端就靠它,一般材質有碳鋼及不銹鋼,頭型有十字或一字槽以利于工具擰緊,左圖為十一字槽,如果沒有特殊說明我公司是默認為這種槽型,請注意。)
    2,手擰套(一般會拉直紋花,材質通常為鋁,有時需據需要進行鋁氧化發黑,如右圖)
    3,壓鉚套(鉚接于面板就靠它了)
    4,彈簧(便于螺釘的伸出縮進及讓整個部件不脫出)
    每個部件生產完成后,組裝成一體并將手擰部分擠壓使其與壓鉚件通過彈簧鑲合在一起,形成一個完整松不脫彈簧面板螺釘.
    松不脫螺絲PF11

    廣州晟峰生產的彈簧螺絲具有較高的性價比.
    其它各種型式的不脫出螺絲價格都很優惠,具體價格歡迎來電咨詢
    左圖規格的松不脫彈簧規格為PF11 M4-0及PF11 M4-1(這一款彈簧螺釘的手擰鋁套為黑色氧化而螺釘部分為鍍黑鎳,以配合特殊的使用環境如機箱面板為黑色的時候以利用顏色一致)
    下附PF11 PF12 PF21 PF22松不脫式彈簧螺釘的安裝方式及規格明細表:
    (下表為常用的標準規格,如需非標的松不脫彈簧螺釘可根據用戶需要訂制)

    PF11與PF12的區別
    PF12松不脫螺釘

    PF11與PF12松不脫螺釘的區別:
    左圖中兩款松不脫螺釘為滾花的PF11類型與不滾花的PF12類型對比,兩種型號的尺寸及其它參考完全一樣,不同的是:
    PF11松不脫螺釘手擰柄為帶有直紋的花齒柄起防滑作用,如左圖中的左邊一款及本頁面中上面的三個圖;
    PF12松不脫螺絲手擰柄為不帶任何紋路的光柄,如左圖中的右邊這一款。
    大多數使用環境為PF11型的松不脫螺釘,也有少數用戶更傾向于選用PF12類型的光柄手擰螺釘.請用戶自行選擇
    PF11 12類松不脫螺釘各部件的材質
    這是我公司PF11 12類松不脫螺釘的各部件的材質及其它參數(熱處理,表面處理等):
    部件名稱PART 材質MATERAIL 牌號N.O 熱處理 硬度 表面SURFACE
    KNOB旋扭: Aluminum 6061鋁 natural Natural/Black
    RETAINER鉚接套: Carbon steel 1215快削鋼 滲碳 HV380-450 Nickel
    SCREW 螺絲: Stainless steel 304不銹鋼 natural Natural
    SPRING 彈簧: Stainless steel 304不銹鋼 固熔 natural Natural
    關于螺釘的槽型的說明

    PF11系列松不脫螺釘按行業標準,其螺釘的槽型分為十字,米字,內六角,內梅花,一字等槽型。我公司默認槽型來十一字,沒有特殊說明的情況下我們默認為十一字,即這樣的槽型:

    十一字是最為通用與適配的一種頭型,為了提高性價比,我公司內部統一了螺釘的槽型,如果您有指定的頭型,請提前告知,我們可以跟據客戶要求生產,PS:不論用戶選擇何種槽型,對整個產品單價(見最上面)不產生影響。

    松不脫螺釘的國標

    關于松不脫螺釘的國標?

    ——放棄這個想法吧朋友,松不脫螺釘沒有國家標準,也沒有國際標準。我公司及國內其它同行公司所執行的標準算是行業默認標準。這些產品標準早期由部分歐美企業所開發并逐步成為國內行業的標準。近來年國內一些權威的電信企業如華為也有制定個別規格的專利型松不脫螺釘,但其應用僅限這些企業內部,尚不足以成為行業標準。

    事實上隨著產業細分化,越來越多的緊固件產品呈專業化訂制化的趨勢,國標因其標準化和寬容度的特性不再能滿足行業應用,將會有越來越多的緊固件產品不再有國標。
