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 slide block with ultra-high rigidity. Background Art

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

[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 number of spherical balls are usually set in the slider, and the spherical balls cause 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 slider sliding, 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 slides against the slide rail. Therefore, CN218844850U is a slider structure for a linear slide rail. It effectively solves the problem of easy wear and short service life of the existing ball slider by setting a sliding body. 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.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] In a preferred embodiment of the present utility model, the oil seal structure includes an oil scraper plate, a positioning protrusion is provided in the middle of the oil scraper plate, a threaded countersunk hole is opened in the middle of the balancing block, the oil scraper plate is threadedly connected to the threaded countersunk hole by a pan head screw, the positioning protrusion is inserted into the end of the threaded countersunk hole, and the surrounding surface of the oil scraper plate is in close contact with the inner wall of the balancing groove.

[0009] In a preferred embodiment of the present invention, a balancing groove is provided in the center of the inner wall of the slide groove, and balancing blocks are provided at positions of the decorative panels corresponding to the balancing groove, and the balancing blocks are slidably connected to the corresponding balancing grooves.

[0013] The beneficial effects of the utility model are:

[0014] The utility model installs an oil seal structure on the balancing block of the decorative plate, and isolates an oil storage space in the balancing groove through two sets of oil seal structures and the sliding-assisting pillar. The oil storage space stores lubricating oil, and the surface seal prevents the lubricating oil from leaking while providing lubrication. As a result, the friction between the slide rail and the sliding-assisting pillar is reduced during the operation of the silent linear slider due to the continuous supply of lubricating oil by the sliding-assisting pillar, thereby significantly reducing the noise generated by friction during the operation of the slider.

[0015] In addition, by providing a coating with a thickness of 2 to 5 microns on the surface of the sliding column, the coating is a high-strength, high-temperature-resistant, low-friction coefficient metal coating (diamond-like coating), which can further effectively reduce noise and increase the lubricity and smoothness of sliding.

The slider seat 300 is provided with mounting grooves 301 on both sides corresponding to the slide rail 100. A sliding column 500 is provided inside the mounting groove 301. The sliding column 500 is a hollow structure with both ends open. A part of the sliding column 500 extends outside the mounting groove 301. The slide rail 100 is provided with a slide groove 101 on both sides along the length direction. A part of the sliding column 500 is slidably connected to the inside of the slide groove 101. Baffles are provided at the front and rear ends of the slider seat 300 from the inside to the outside. 400 and the decorative panel 200, the baffle 400 and the decorative panel 200 are fixed to the slider seat 300 by bolts, the baffle 400 is close to the ends of the two sliding columns 500, a balancing groove 102 is opened in the center of the inner wall of the slide groove 101, and the decorative panel 200 is provided with a balancing block 201 at the corresponding balancing groove 102. The balancing block 201 is slidably connected with the corresponding balancing groove 102, and an oil seal structure is provided in the middle of the balancing block 201. The two sets of oil seal structures and the sliding columns 500 inside the same balancing groove 102 isolate the oil storage space in the balancing groove 102, and the lubricating oil is stored in the oil storage space.

[0024] In a preferred embodiment of the present invention, the oil seal structure further includes an oil scraper 203, a positioning protrusion 2031 is provided in the middle of the oil scraper 203, a threaded countersunk hole 2011 is opened in the middle of the balancing block 201, the oil scraper 203 is threadedly connected to the threaded countersunk hole 2011 through a pan head screw 202, the positioning protrusion 2031 is inserted into the end of the threaded countersunk hole 2011, and the surrounding surfaces of the oil scraper 203 are in close contact with the inner wall of the balancing groove 102.

[0025] In a preferred embodiment of the present invention, further, a balancing groove 102 is opened in the center of the inner wall of the slide groove 101, and a balancing block 201 is provided at the corresponding balancing groove 102 of the decorative panel 200, and the balancing block 201 is slidably connected to the corresponding balancing groove 102.

[0026] In a preferred embodiment of the present invention, further, the two balancing blocks 201 are integrally formed with the decorative plate 200 .

[0027] In a preferred embodiment of the present invention, further, the sliding column 500 is a cylindrical structure, and the shapes of the mounting groove 301 and the sliding groove 101 match the shape of the sliding column 500.

[0028] In a preferred embodiment of the present invention, further, the low-friction coating is a low-friction coefficient metal coating with a thickness of two to five microns.

[0029] Specifically, as shown in the figure, a semicircular mounting groove 301 is provided inside the slider seat 300 of the ultra-high rigidity improved silent linear slider, and a semicircular slide groove 101 is provided on the side of the slide rail 100. A sliding column 500 is provided between the slide rail 100 and the slider seat 300, and baffles 400 are provided at both ends of the slider seat 300. The baffles 400 prevent the sliding column 500 from detaching from the slider seat 300, and a decorative plate 200 is provided again on the outside of the baffle 400 to fix the sliding column 500 and the slider seat 300. The positional relationship between the slider seat 300 and the sliding post 500 is a solid cylindrical structure. Two sets of oil seal structures and the sliding post isolate an oil storage space in the balance groove 102. The oil storage space stores lubricating oil. The surface seal prevents oil leakage while providing lubrication. As a result, the sliding post 500 continuously provides lubricating oil during operation of the silent linear slider, thereby reducing the friction between the slide rail and the sliding post 500, thereby significantly reducing the noise generated by friction during operation of the slider 100.

[0032] Place the slide-assisting post 500 in the slider groove, push the slide rail 100 into the slider, place baffles 400 at both ends of the slider seat 300, and fill the balancing groove 102 with lubricating oil through the threaded countersunk hole 2011. After the lubricating oil is filled, insert the baffle 400 into the balancing groove 102 and fasten it to the balancing block 201 with the pan head screw 202 to prevent the lubricating oil in the balancing groove 102 from leaking.

[0033] The two sets of oil seal structures and the anti-sliding column 500 isolate the oil storage space in the balancing groove 102. The oil storage space stores lubricating oil without oil leakage, thereby playing a lubricating role. As a result, the balancing groove 102 continuously provides lubricating oil during the operation of the silent linear slider, thereby reducing the friction between the slide rail 100 and the anti-sliding column 500, thereby significantly reducing the slider's operation.

[0034] The present invention has another advantage. By providing a coating with a thickness of 2 to 5 microns on the surface of the sliding column 500, the coating is a high-strength, high-temperature-resistant, low-friction metal coating (diamond-like coating), which can effectively reduce noise and increase the lubricity and smoothness of sliding.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
