Description

Technical Field

[0001] The present invention relates to a linear slide rail, and in particular to a guide lubrication structure of the linear slide rail. Background Art

[0002] A linear slide primarily involves mounting a slider structure on a track to produce reciprocating linear motion. The slider structure consists of a U-shaped slider, two end caps located on opposite sides of the slider, multiple balls within the slider, and a retaining assembly to position the balls. The balls reduce friction between the slider and the track during relative motion, resulting in smoother movement.

[0003] Furthermore, to improve the precision and smoothness of linear slides, the balls in these guides must be adequately lubricated to maintain proper operation. Linear guides are typically lubricated by installing a lubricating element on the outer end of the slider to lubricate the rail and balls. However, long-term wear and tear on these lubricating elements can easily cause deformation, resulting in an inability to maintain uniform contact with the rail. This can lead to uneven lubrication, poor lubrication, and reduced service life.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned existing technologies and applied scientific theories to try his best to solve the above-mentioned problems, which has become the goal of the applicant's improvement. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a guide lubrication structure for a linear slide rail, wherein the lubricating element moves toward the slide rail under the push of an elastic arm and the guidance of a guide plate and a guide post, so that the lip is tightly attached to the lubrication portion to continuously lubricate the slide rail, thereby improving the smoothness and service life of the linear slide rail.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a guide lubrication structure for a linear slide rail for lubricating a slide rail, and the guide lubrication structure includes an oil tank and a first lubricating element. The oil tank includes a frame plate, a first elastic arm, a guide plate and a first guide column. The frame plate encloses an oil storage space. The first elastic arm is connected to the frame plate and protrudes toward the oil storage space. The guide plate and the first guide column are arranged in the oil storage space. The first lubricating element includes an extended arm, a first abutting arm, a first hollow groove and a first lip. The extended arm is obliquely attached to the guide plate. The first elastic arm elastically pushes against the first abutting arm. The first hollow groove is penetrated by the first guide column and is located between the extended arm and the first abutting arm. The first lip is located on one side of the slide rail. When the first lubricating element moves toward the slide rail under the elastic push of the first elastic arm, the guide plate pushes against the extended arm and the first guide column pushes against the first hollow groove, so that the first lip abuts against the slide rail.

[0007] Compared to conventional technology, the lubricating element of the present invention is moved toward the slide rail by the elastic push of the elastic arm, and the guide plate pushes against the hollow groove along the extension arm and the guide column, so that the lip presses against the slide rail; accordingly, the lubricating element can continuously lubricate the slide rail during use, thereby improving the smoothness and service life of the linear slide rail during use, and increasing the practicality of the present invention.

[0039] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the drawings are only provided for reference and explanation and are not intended to limit the present invention.

[0040] Please refer to Figure 1 , is a three-dimensional schematic diagram of the linear slide rail of the present invention. The present invention is a guide lubrication structure 1 of a linear slide rail, which is arranged on one side of a slider 2 to lubricate a slide rail 3 inserted in the slider 2.

[0041] Please refer to Figures 2 to 4 , respectively, are a three-dimensional exploded schematic diagram of the guide lubrication structure of the present invention, a three-dimensional appearance schematic diagram of the guide lubrication structure combined with the slider, and a combined cross-sectional view of the guide lubrication structure and the slider. Figure 2 As shown, the guide lubrication structure 1 includes an oil tank 10 and a first lubricating element 20. The oil tank 10 is coupled to one side of the slider 2. The first lubricating element 20 is disposed in the oil tank 10. The guide lubrication structure 1 will be described in more detail below.

[0042] The oil tank 10 includes a frame plate 11, a first elastic arm 12, a guide plate 13, and a first guide post 14. The frame plate 11 encloses an oil storage space 110. The first elastic arm 12 is integrally formed with the frame plate 11. The first elastic arm 12 is connected to the frame plate 11 and protrudes toward the oil storage space 110. The guide plate 13 and the first guide post 14 are disposed within the oil storage space 110.

[0043] Furthermore, the guide lubrication structure 1 further includes a side cover 30 . The side cover 30 covers the oil storage space 110 and is combined with the oil tank 10 .

[0044] The first lubricating element 20 is disposed in the oil storage space 110. The first lubricating element 20 comprises an extending arm 21, a first abutting arm 22, a first hollow groove 23, and a first lip 24. The extending arm 21 obliquely contacts the guide plate 13. The first elastic arm 12 elastically pushes against the first abutting arm 22. The first guide post 14 is inserted into the first hollow groove 23 and is located between the extending arm 21 and the first abutting arm 22. The first lip 24 is located on one side of the slide rail 3.

[0045] It should be noted that the oil storage space 110 can be filled with oil such as lubricating oil or butter. The lubricating oil is retained in the first hollow groove 23 and slowly flows toward the lower side of the first lubricating element 20, thereby increasing the lubricating service life of the first lubricating element 20.

[0046] Accordingly, when the first lubricating element 20 moves toward the slide rail 3 under the elastic push of the first elastic arm 12, the guide plate 13 pushes against the extension arm 21 and the first guide column 14 pushes against the first hollow groove 23, thereby causing the first lip 24 to press against the slide rail 3.

[0047] In this embodiment, the oil tank 10 further includes a second elastic arm 15 and a second guide post 16 disposed within the oil storage space 110. Furthermore, the first lubricating element 20 further includes a second abutting arm 25, a second hollow groove 26, and a second lip 27. The second elastic arm 15 is connected to the frame plate 11 and protrudes toward the oil storage space 110. The second elastic arm 15 elastically pushes against the second abutting arm 25. The second lip 27 is spaced below the first lip 24. The second guide post 16 is positioned within the second hollow groove 26 and is located between the second abutting arm 25 and the second lip 27.

[0048] More specifically, the guide plate 13 is an oblique plate. The side of the guide plate 13 that abuts the extension arm 21 forms a first angle A with the horizontal direction. Furthermore, the side of the extension arm 21 that abuts the guide plate 13 forms a second angle B with the horizontal direction. The second angle B is greater than the first angle A.

[0049] Furthermore, one side of the first guide post 14 abuts against an inner wall of the first hollow groove 23, such that the other adjacent side of the first guide post 14 forms a third angle C with an inner wall of the first hollow groove 23. Furthermore, the first guide post 14 and the first hollow groove 23 are located above the first lip 24. The first guide post 14 pushes against the first hollow groove 23, causing the first lip 24 to abut against an upper corner of the slide rail 3.

[0050] Accordingly, when the first abutting arm 22 of the first lubricating element 20 is elastically pushed by the first elastic arm 12 and moves toward the slide rail 3, one side of the second guide column 16 abuts against an inner wall surface of the second hollow groove 26, so that the other adjacent side of the second guide column 16 forms a fourth angle D with an inner wall surface of the second hollow groove 26.

[0051] Furthermore, the second guide post 16 and the second hollow groove 26 are located below the second lip 27. The second guide post 16 pushes against the second hollow groove 26, causing the second lip 27 to abut against a lower corner of the slide rail 3. Furthermore, the fuel tank 10 has a second guide piece 17 formed on one side of the second guide post 16. This second guide piece 17 abuts against the lower side of the second lip 27. The second guide piece 17 also serves a guiding function, pushing the lower side of the second lip 27 against the lower corner of the slide rail 3.

[0052] It should be noted that the guide lubrication structure 1 further includes a second lubricating element 20a spaced apart from the first lubricating element 20. The second lubricating element 20a is disposed on the other side of the slide rail 3 relative to the first lubricating element 20. Furthermore, the first angle A, the second angle B, the third angle C, and the fourth angle D can be adjusted based on actual usage.

[0053] After the guide lubrication structure 1 is configured as described above, the first lubricating element 20 is elastically pushed by the first elastic arm 12 and moves toward the slide rail 3. Furthermore, the first lubricating element 20 is simultaneously pushed by the first guide post 14, the second guide post 16, and the second guide piece 17, causing the first lip 24 to abut against the upper corner of the slide rail 3 and the second lip 27 to abut against the lower corner of the slide rail 3.

[0054] Furthermore, the structure and configuration of the second lubricating element 20a are identical to those of the first lubricating element 20 and will not be further described herein. Furthermore, there are a plurality of first elastic arms 12. There are a pair of guide plates 13 and a pair of first guide posts 14. Multiple first elastic arms 12 are disposed on two opposing inner wall surfaces of the frame plate 11. The pair of guide plates 13 and the pair of first guide posts 14 are symmetrically disposed relative to the slide rail 3. Accordingly, the first lubricating elements 20, 20a can continuously and progressively lubricate the slide rail 3 during use of the linear slide rail, thereby improving the smoothness and service life of the linear slide rail.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to define the patent scope of the present invention. Other equivalent variations that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
