Description

Technical Field

[0001] The utility model belongs to the technical field of linear slide rails, and in particular relates to an improved silent linear guide rail system. Background Art

[0002] Slide rail devices are widely used in mechanical equipment, transmission systems or furniture to facilitate relative sliding between a first element and a second element.

[0003] In the existing slide rail device, it usually includes a guide rail and a slider, and the guide rail is slidably installed on the slider. In order to reduce the friction of the slider on the guide rail, a plurality of spherical balls are usually arranged in the slider, and the spherical balls have rolling friction with the slider during the sliding process of the slider. Although the use of a sliding device with balls can reduce the friction of the slide rail device, the wear between the balls is uneven, and the balls after wear are likely to no longer be standard spherical shapes. The rolling direction of balls that are not standard spherical shapes is selective. For example, when the ball becomes ellipsoidal, it is easy to roll around its long axis. At this time, if the long axis of the ellipsoidal ball is consistent with the sliding direction of the slider in the slide groove, the ball is not easy to roll and appears to slide, which will increase the friction of the sliding slider, thereby affecting the service life of the slide rail device;

[0004] At the same time, the rolling friction between the ball and the slide rail will generate considerable noise, and the noise will be even greater when the ball is worn and rubbed against the slide rail. Therefore, CN218844850U is a slider structure of a linear slide rail. By setting a sliding body, it effectively solves the problem of easy wear and short service life of the existing ball slider. However, due to the sliding friction between the sliding body and the slide rail, the noise during operation will be relatively large. Therefore, in order to solve the problems of high noise, easy wear and short service life of the slider, it is urgent to design a silent linear slider to solve the above problems.

The slider seat 300 is provided with mounting grooves 301 on both sides of the slide rail 100. A slide-assisting column 400 is arranged inside the mounting groove 301. The slide-assisting column 400 is a hollow structure with two ends open. A plurality of lubrication holes 401 are evenly provided on the surface of the slide-assisting column 400 and near both ends. A portion of the slide-assisting column 400 extends outside the mounting groove 301. The slide rail 100 is provided with slide grooves on both sides along the length direction. 102, a part of the sliding column 400 is slidably connected to the inside of the slide groove 102, and the front and rear ends of the slider seat 300 are provided with a scraper plate 500 and a decorative plate 200 in sequence from the inside to the outside. The scraper plate 500 and the decorative plate 200 are fixed to the slider seat 300 by bolts, and the scraper plate 500 is sleeved on the outside of the two sliding columns 400, and the two ends of the sliding column 400 are respectively blocked by two decorative plates 200, the interior of the sliding column 400 is filled with lubricating oil, and the surface of the sliding column 400 is coated with a layer of low-friction coating.

[0024] In a preferred embodiment of the present invention, further, a balancing groove 101 is opened in the center of the inner wall of the slide groove 102, and a balancing block 202 is arranged at the decorative plate 200 corresponding to the balancing groove 101, and the balancing block 202 is slidably connected to the corresponding balancing groove 101.

[0025] In a preferred embodiment of the present invention, further, two balancing blocks 202 are integrally formed with the decorative panel 200 .

[0026] In a preferred embodiment of the present invention, further, an oil seal protrusion 201 is provided on one side of the decorative plate 200 close to the slider seat 300 and corresponding to the opening of each sliding column 400, and the oil seal protrusion 201 is plugged and sealed at the end opening of the corresponding sliding column 400.

[0027] In a preferred embodiment of the present invention, further, the sliding column 400 is in a cylindrical structure, and the shapes of the mounting groove 301 and the balancing groove 101 match the shape of the sliding column 400.

[0028] In a preferred embodiment of the present invention, further, the inner surfaces of the mounting groove 301 and the balancing groove 101 are completely covered with a plurality of lubrication holes 401 .

[0029] In a preferred embodiment of the present invention, further, the low friction coating adopts a low friction coefficient metal coating, and its thickness is two to five microns.

[0030] Specifically, as shown in the figure, a semicircular mounting groove 301 is provided inside the slider seat 300 of the silent linear slider, and a semicircular sliding groove 102 is provided on the side of the slide rail 100. A sliding column 400 is provided between the slide rail 100 and the slider seat 300, and oil scrapers 500 are provided at both ends of the slider seat 300. The oil scrapers 500 prevent the sliding column 400 from being separated from the multifunctional slider, and a decorative plate 200 is provided again on the outer side of the oil scraper 500 to fix the positional relationship between the sliding column 400 and the slider seat 300.

[0031] The sliding column 400 is a cylindrical structure with a hollow interior. Lubricating holes 401 are provided at the left and right ends of the middle sliding column 400 , and the lubricating holes 401 are connected to the hollow part.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
