As shown in FIG. 3 again, the oil scraper 20 of the present invention includes a metal piece 30 and a soft covering body 40.

金屬件30在本實施例中所使用的材質為鐵,但不以此為限。金屬件30是以沖壓加工的方式所製成的一體式結構,厚度為0.2-0.8mm。如圖4及圖5所示,金屬件30具有二個相對之端部31、一個橋接部32及二個相對之支撐部33,其中,橋接部32以其二端分別經由一個第一彎折部34連接一個端部31,該等支撐部33分別經由一個第二彎折部35連接一個端部31之底緣且分別自一個端部31之底緣往內斜伸而出,使得金屬件30在該等端部31的下方分別形成一個填料槽36,每一個填料槽36鄰接一個支撐部33及一個第二彎折部35。此外,每一個端部31具有一個開口朝上之第一開槽312,橋接部32的中央具有一個開口朝上之第二開槽322。The material used for the metal part 30 in this embodiment is iron, but it is not limited to this.

In addition, each end portion 31 has a first slot 312 with an opening upward, and the center of the bridge portion 32 has a second slot 322 with an opening upward.

請繼續參閱圖5,每一個填料槽36具有一個介於20-60度之間的傾斜角θ,若傾斜角θ小於20度,填料槽36會太小而不利於射出成型作業,若傾斜角θ大於60度,填料槽36會太大而過於靠近第一開槽312,導致端部31的結構強度會受到影響,所以傾斜角θ的範圍在20-60度之間為較佳實施態樣。此外,如圖5所示,每一個支撐部33具有一個第一水平長度H 1,第一水平長度H 1為支撐部33之一個支撐端332與端部31之一個外側邊314之間的長度,各個填料槽36具有一個第二水平長度H 2,兩者滿足以下關係式:0.4H 1≦H 2≦0.7H 1,若H 2小於0.4H 1,填料槽36會太小而不利於射出成型作業,若H 2大於0.7H 1,填料槽36會太大而影響支撐部33的結構強度,所以H 2的範圍在0.4H 1-0.7H 1之間為較佳實施態樣。 Please continue to refer to FIG. 5, each filling groove 36 has an inclination angle θ between 20-60 degrees. If the inclination angle θ is less than 20 degrees, the filling groove 36 will be too small to facilitate injection molding operations. If θ is greater than 60 degrees, the filling groove 36 will be too large and too close to the first slot 312, which will affect the structural strength of the end portion 31. Therefore, the range of the inclination angle θ between 20-60 degrees is a preferred embodiment. . In addition, as shown in FIG. 5, each support portion 33 has a first horizontal length H 1 , and the first horizontal length H 1 is between a support end 332 of the support portion 33 and an outer side 314 of the end 31 Each packing trough 36 has a second horizontal length H 2 , and both satisfy the following relationship: 0.4H 1 ≦H 2 ≦0.7H 1 , if H 2 is less than 0.4H 1 , the packing trough 36 will be too small to be advantageous In the injection molding operation, if H 2 is greater than 0.7H 1 , the filling groove 36 will be too large and affect the structural strength of the support portion 33. Therefore, the range of H 2 is between 0.4H 1 -0.7H 1 as a preferred embodiment.

請再回到圖3,本創作之刮油片20在製作完成後具有以下的尺寸規格:L≦25mm,W≦7.5mm,t≦1.2mm,ts≦0.6mm,其中的L為刮油片20的長度,W為刮油片20的高度,t為刮油片20在第一穿孔312及第二穿孔422以外的厚度,ts為刮油片20在對應第一穿孔312的厚度(亦即金屬件30的厚度),如此即可適用於微型線性滑軌10。Please go back to Figure 3. The oil scraper 20 of this creation has the following dimensions after production: L≦25mm, W≦7.5mm, t≦1.2mm, ts≦0.6mm, where L is the oil scraper The length of 20, W is the height of the oil scraper 20, t is the thickness of the oil scraper 20 outside the first perforation 312 and the second perforation 422, and ts is the thickness of the oil scraper 20 at the corresponding first perforation 312 (ie The thickness of the metal piece 30), so that it can be applied to the miniature linear slide 10.

由上述可知,本創作之刮油片20透過該等填料槽36的特殊設計,讓金屬件30在不影響支撐部33的結構強度下於該等填料槽36進行軟質包覆體40的射出成型作業,使金屬件30在前述作業當中不易產生結構變形而能與軟質包覆體40穩固地結合在一起,藉以達到增加結構強度及延長使用壽命的效果。It can be seen from the above that the oil scraper 20 of the present invention through the special design of the filling grooves 36 allows the metal parts 30 to perform injection molding of the soft covering body 40 in the filling grooves 36 without affecting the structural strength of the supporting portion 33 The operation makes the metal part 30 difficult to produce structural deformation during the aforementioned operation and can be firmly combined with the soft covering body 40, thereby achieving the effect of increasing the structural strength and extending the service life.
