Abstract

The present invention relates to a linear sliding rail with a dust-proof sheet, which includes: a track, a sliding block sleeved onto the track for moving relative to the track; a plurality of rolling members installed between the track and the sliding block; two terminal caps respectively installed at two ends of the sliding block, wherein the terminal cap is provided with an installing groove relative to the track, and the installing groove has a wall face; and a dust-proof sheet arranged on the installing groove, wherein the dust-proof sheet has a main body and two elastic parts respectively extending from two sides of the main body. One of the elastic parts is abutted against the wall face, and the other elastic part is abutted against the surface of the track, thereby using the elasticity of the elastic parts to timely adjust the contacting pressure between the dust-proof sheet and the track. When the elastic part that contacts the track has been abraded, the other elastic part gives elasticity to make up the gap of abrasion.

Description

Linear slide with dust-proof plate

The invention is a linear slide rail, especially a linear slide rail with a dustproof sheet.

Please refer to the sixth and seventh figures. The conventional dust-proof blade (10) is a clip of a soft left blade (14) and a right blade (15) with two metal plates (11, 12). On the left and right sides of the chute (13), the left blade (14) and the right blade (15) are respectively formed with a lower edge portion (143, 153), an upper lip portion (141, 151), and a lower lip portion. (142, 152), when the dust-proof sheet (10) is applied, a dust-proof sheet (10) is set on each end cap (51, 52) attached to both ends of the slider (50), and the left and right blades ( 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 the left, The lower edges (143, 153) of the right scraper blades (14, 15) abut against the left and right sides of the upper end surface of the slide rail (40). The function of the conventional dust wiper blade (10) is attached to the slider (50). ) When reciprocating 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 end covers (10) and entering the slide (50). In the block (50) and the end cover (10) Ring reflux of the ball (45) stained with dust, it can not smooth scrolling displacement.
However, after long-term use of the conventional dust wiper (10), the lower edge (143, 153), upper lip (141, 151), and lower lip (142) of the left and right scrapers (14, 15) , 152) will wear out because of this, there will be a gap between the two left and right scrapers (14, 15) and the slide rail (40), you must remove the entire dust sheet (10), and then replace it with a new one (10) The conventional dust-proof sheet (10) must not only stop when it is disassembled and assembled, and it is extremely time-consuming. Furthermore, after dismantling the entire dust-proof sheet (10), it is unusable and must be discarded. Waste of wasted materials; therefore, the conventional dust sheet (10) needs to be improved.

In view of the above problems, the main object of the present invention is to develop a dust-proof sheet capable of automatically adjusting the interference amount with the track.
In order to achieve the above-mentioned object, the present invention is a linear slide rail with dust-proof plate, which includes: a track; a slider, which is sleeved on the track and can run relative to the track; a plurality of rolling elements, which are provided on the track; Between the track and the slider; the two end covers are respectively arranged at the two ends of the slider, the end cover is provided with a mounting groove opposite to the track, the mounting groove has a wall surface, and a dustproof plate is provided on the installation Groove, the dustproof sheet has a main body and two elastic portions respectively extending from two sides of the main body, one elastic portion is in contact with the wall surface, and the other elastic portion is in contact with the surface of the track.
Preferably, the mounting groove and the dust-proof sheet are both generally shaped.
Preferably, the mounting groove is provided with a positioning portion, the dust-proof sheet is provided with a positioning hole opposite to the positioning portion, and the positioning hole is sleeved on the positioning portion.
Preferably, a plurality of ribs are provided between the elastic portion and the body.
Preferably, the two end caps are respectively covered with a fixed piece, and the fixed piece limits the degree of freedom of the dust piece in the axial direction.
Preferably, the elastic part of the dust-proof sheet is continuously in contact with the wall surface or the surface of the track.
By this, the two elastic parts provided by the dust-proof sheet of the present invention respectively abut the wall surface and the surface of the track, and the contact pressure between the dust-proof sheet and the track can be adjusted in time by the elasticity of the elastic part. When the part is worn, an elastic force is given by another elastic part to make up for the abrasion gap, so as to prevent foreign matter from invading the inside of the slider.
