Description

Linear slide with dustproof sheet

本發明係為一種線性滑軌，尤指一種具防塵片之線性滑軌。The invention relates to a linear slide rail, in particular to a linear slide rail with a dustproof sheet.

請參閱第六圖、第七圖所示，習知之防塵片（10），其係以兩金屬片（11、12）將一軟質左刮片（14）及右刮片（15）分別夾掣於滑槽（13）之左側及右側，該各左刮片（14）及右刮片（15）係分別形成有一下緣部（143、153）及上唇部（141、151）、下唇部（142、152），該防塵片（10）應用時，係於滑塊（50）兩端面之端蓋（51、52）上各組設一防塵片（10），該左、右刮片（14、15）之上唇部（141、151）、下唇部（142、152）係各抵靠於滑軌（40）兩側之滾道（41、42、43、44）中，且左、右刮片（14、15）之下緣部（143、153）係抵靠於滑軌（40）上端面之左右兩側，該習知防塵片（10）之功能，係在滑塊（50）與滑軌（40）作往復運動位移時，將滑軌（40）上粉塵預先予以刮除，以防止粉塵經由兩端蓋（10），再進入滑塊（50）中，而使在滑塊（50）及兩端蓋（10）中循環迴流之滾珠（45）沾到粉塵，使其無法平順的滾動位移。
惟，該習知之防塵片（10）經長期使用後，該兩左、右刮片（14、15）之下緣部（143、153）、上唇部（141、151）、下唇部（142、152）會因此而磨損，兩左、右刮片（14、15）與滑軌（40）間則會產生間隙，則須將整個防塵片（10）拆掉，再換上新的防塵片（10），該習知防塵片（10）在拆解及組裝時，不僅須停機，且極為耗時，再者，整個防塵片（10）拆解後，即不堪使用而須丟棄，而極浪費浪費材料；是以，該習知之防塵片（10）乃有待改良。 Referring to the sixth and seventh figures, the conventional dustproof sheet (10) is formed by sandwiching a soft left blade (14) and a right blade (15) with two metal sheets (11, 12). On the left and right sides of the chute (13), the left and right blades (14) and the right blade (15) are respectively formed with lower edge portions (143, 153) and upper lip portions (141, 151) and lower lip portions. (142, 152), when the dustproof piece (10) is applied, a dustproof piece (10) is disposed on each of the end covers (51, 52) on both end faces of the slider (50), and the left and right blade ( 14, 15) the upper lip (141, 151) and the lower lip (142, 152) are each abutted against the raceways (41, 42, 43, 44) on both sides of the slide rail (40), and left, The lower edge portions (143, 153) of the right blade (14, 15) abut against the left and right sides of the upper end surface of the slide rail (40), and the function of the conventional dustproof sheet (10) is attached to the slider (50). When the reciprocating displacement is made with the slide rail (40), the dust on the slide rail (40) is scraped off in advance to prevent the dust from entering the slider (50) through the two end covers (10), thereby making the slide Block (50) and both ends of the cover (10) The ball ring reflux (45) stained with dust, it can not smooth scrolling displacement.
However, after the conventional dustproof sheet (10) is used for a long period of time, the lower left edge portions (143, 153), the upper lip portion (141, 151), and the lower lip portion (142) of the two left and right blades (14, 15). 152) will wear out. If there is a gap between the two left and right blades (14, 15) and the slide rail (40), the entire dustproof piece (10) must be removed and replaced with a new dustproof piece. (10) When the conventional dustproof piece (10) is disassembled and assembled, it not only has to be shut down, but also is extremely time consuming. Moreover, after the entire dustproof piece (10) is disassembled, it is unbearable and must be discarded. Waste of wasted material; therefore, the conventional dustproof sheet (10) needs to be improved.
