Description

Technical Field

[0001] The present invention relates to the technical field of linear guide rails, in particular to a linear guide rail with a dustproof structure. Background Art

[0002] Linear guides are used for high-precision or high-speed linear reciprocating motion. They can withstand a certain amount of torque and achieve high-precision linear motion under high loads. Linear guides support and guide moving parts, performing reciprocating linear motion in a given direction. Depending on the nature of their friction, linear guides can be categorized as sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides.

Detailed implementation manners

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0037] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 As shown in

[0038] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown, the sliding structure 2 includes a slider 201. The slider 201 is provided on the slide rail 1. The top side of the slide rail 1 is in a rhombus structure. Pulley 202 is rotatably connected to both sides of the slider 201. The pulley 202 is obliquely arranged. The end of the pulley 202 is rotatably connected to a fixed sleeve 204. The fixed sleeve 204 is fixedly connected to the inner side of the slider 201. A plurality of balls 203 are annularly arranged on the side of the pulley 202. The side of the pulley 202 is slidably connected to the fixed sleeve 204 through the balls 203.

[0039] The top side of the slide rail 1 is in a rhombus structure, and a pulley 202 obliquely arranged on each side of the slider 201 provides support and sliding effect for the slider 201. Due to the inclined plane structure on both sides of the slide rail 1, it is difficult for large particles of impurities to remain on the slide rail 1 and affect the sliding of the slider 201. At the same time, the two obliquely arranged pulleys 202 slide on the slide rail 1, which can prevent the slider 201 from shifting during the sliding process. The balls 203 arranged between the fixed sleeve 204 and the pulley 202 can reduce the wear of the top side part of the pulley 202 during the rolling process.

[0040] Specifically, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 As shown, the connecting structure 3 includes a fixed seat 301. The fixed seat 301 is fixedly connected to the end of the slide rail 1. A connecting rotating block 302 is rotatably connected to the fixed seat 301. The connecting rotating block 302 is in a "U" - shaped structure. A clamping groove 306 is formed inside the connecting rotating block 302. A clamping block 304 is slidably connected to the side of the slider 201. A first spring 305 is fixedly connected between the clamping block 304 and the slider 201. The end of the clamping block 304 is clamped with the connecting rotating block 302 through the clamping groove 306. Pushing rods 307 are respectively slidably connected to both ends of the connecting rotating block 302. A second spring 308 is fixedly connected between the pushing rods 307 and the connecting rotating block 302. The end of the pushing rod 307 is in an arc - shaped structure. A release rod 303 is rotatably connected to the middle of the connecting rotating block 302. An arc - shaped notch is provided on the side of the release rod 303. The arc - shaped end of the pushing rod 307 abuts against the release rod 303 through the notch on the side of the release rod 303. The other end of the pushing rod 307 is arranged on the side of the clamping block 304.

[0041] When it is necessary to clean the slide rail 1 or the slider 201, the user can rotate the connecting rotating block 302 provided on the fixed seat 301 at the end of the slide rail 1 to the horizontal state, and then slide the slider 201 until it abuts against the fixed seat 301. At this time, the engaging block 304 provided on the side of the slider 201 will engage with the card slot 306 on the side of the connecting rotating block 302. With the rotation angle limit of the connecting rotating block 302, the slider 201 can be fixed on the fixed seat 301. When the user needs to release the slider 201, the user can rotate the release lever 303 on the connecting rotating block 302. At this time, the end of the push rod 307 will disengage from the arc-shaped groove on the side of the release lever 303 and slide to one side. At this time, the end of the push rod 307 will push the engaging block 304 to release the connection state between the slider 201 and the fixed seat 301.

[0042] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 13As shown, the driving structure 6 includes a central slide rod 603, the middle part of the slider 201 is slidably connected to the central slide rod 603, the central slide rod 603 is perpendicular to the side of the fixed seat 301, and an eighth spring 615 is fixedly connected between the side of the central slide rod 603 and the slider 201. The pulley 202 is perpendicular to the adjacent side of the central slide rod 603. The end of the pulley 202 is rotatably connected to the worm gear sleeve 602. The inner side of the worm gear sleeve 602 is provided with a connecting groove 606. The end of the pulley 202 is slidably connected to the connecting groove 606. The connecting column 604 is fixedly connected to the pulley 202 with a third spring 605. The two side ends of the connecting column 604 are slidably connected to the worm gear sleeve 602 through the connecting groove 606. The side of the central slide 603 is provided with a positioning groove 611. The end of the connecting column 604 is a hemispherical structure. The spherical end of the connecting column 604 abuts against the side of the central slide 603. The raised part of the middle side of the connecting rotary block 302 abuts against the first inclined block 608. The inclined side of the first inclined block 608 is slidably connected to the A ejector block 610 is connected, and the ejector block 610 is slidably connected to the inner side of the fixed seat 301. A fourth spring 609 is fixedly connected between the ejector block 610 and the fixed seat 301. The end of the ejector block 610 conflicts with the end of the central slide 603. A worm 601 is provided on both sides of the central slide 603 in parallel. The worm 601 is rotatably connected to the inner side of the slider 201. The side of the worm 601 is engaged with the worm gear sleeve 602 provided on the same side. A slot 612 is provided at the end of the worm 601. Two drive shafts 613 are rotatably connected to the inner side of the fixed seat 301. The drive shafts 613 are located on the same straight line as the worm 601 on the same side. The two fixed seats 301 are rotatably connected to the side facing away from the slide rail 1 with a rotary cover 607. The ends of the drive shafts 613 are engaged with the inner side of the rotary cover 607. The ends of the drive shafts 613 are slidably connected to a plug rod 616. The end of the plug rod 616 is slidably connected to the worm 601 through a slot 612. A seventh spring 614 is fixedly connected between the plug rod 616 and the drive shaft 613.

[0043] When the slider 201 is fixedly connected to the connecting rotating block 302, since the connecting rotating block 302 rotates, the convex structure in the middle of the connecting rotating block 302 will push the first inclined surface block 608 to slide downward, and then push the end of the ejecting block 610 to extend out of the side surface of the fixed seat 301 through the inclined side surface of the first inclined surface block 608. Thus, when the end of the slider 201 abuts against the fixed seat 301, the end of the ejecting block 610 will push the central slide bar 603 arranged in the slider 201. As the central slide bar 603 slides, the end of the connecting column 604 at the end of the pulley 202 will disengage from the positioning groove 611 on the side surface of the central slide bar 603. At this time, both side ends of the connecting column 604 will be engaged in the connecting groove 606 inside the worm gear sleeve 602. At this time, the worm gear sleeve 602 and the pulley 202 will rotate synchronously. On the other hand, since the slider 201 abuts against the side surface of the fixed seat 301, the end of the insertion rod 616 on the side surface of the fixed seat 301 will slide into the slot 612 at the end of the worm 601. At this time, the user can rotate the screw cap 607 located on the side surface of the fixed seat 301. The inner side of the screw cap 607 meshes with the end of the driving shaft 613. The rotation of the screw cap 607 will drive the two driving shafts 613 and the insertion rod 616 sliding on the driving shaft 613 to rotate simultaneously. Further, the insertion rod 616 will drive the worm 601 to rotate, and the worm 601 will drive the pulley 202 to rotate through the worm gear sleeve 602. By manually controlling the rotation of the pulley 202 arranged at the bottom side of the slider 201, it is convenient to fully clean the impurities that may adhere to the side surface of the pulley 202.

[0044] Specifically, as Figure 9 shown, the cleaning structure 7 includes a cleaning scraping block 701. The side surface of the pulley 202 is provided with a cleaning scraping block 701. The cleaning scraping block 701 is slidably connected to the inside of the slider 201. One side of the cleaning scraping block 701 abuts against the pulley 202. The end of the cleaning scraping block 701 is slidably connected with a pushing block 702. A fifth spring 703 is fixedly connected between the pushing block 702 and the cleaning scraping block 701. A sixth spring 704 is fixedly connected between the two pushing blocks 702 on the same side. The side surface of the pushing block 702 is an inclined surface structure. A second inclined surface block 705 is slidably connected between the two pushing blocks 702 through the inclined surface. An arc-shaped protrusion is provided in the middle of the central slide bar 603. The end of the second inclined surface block 705 abuts against the protrusion on the side surface of the central slide bar 603;

[0045] When the slider 201 and the fixed seat 301 are in a connected state, the central slide bar 603 will slide under the push of the ejecting block 610. At this time, the convex structure in the middle of the central slide bar 603 will move to the end position of the second inclined plane block 705 and push it. The end of the second inclined plane block 705 is in a triangular structure. The two inclined sides of the second inclined plane block 705 will push the squeezing blocks 702 on both sides to both sides respectively. Then, through the fifth spring 703, the cleaning scraping block 701 will be pushed towards the adjacent pulley 202 until the side of the cleaning scraping block 701 is in close contact with the side of the pulley 202. At this time, the user rotates the rotary cover 607 to drive the pulley 202 to rotate, so as to scrape off the impurities attached to the side of the pulley 202 and maintain the smooth sliding of the slider 201.

[0046] Specifically, the lifting structure 5 includes a lifting block 501. The two sides of the slide rail 1 are slidably connected with the lifting block 501. The lifting block 501 abuts against the bottom side of the slider 201. The bottom side of the lifting block 501 is provided with a convex structure. The bottom side of the lifting block 501 is slidably connected with a first rack 502. A plurality of grooves 505 are formed in the first rack 502. The end of the first rack 502 is slidably connected to the inside of the fixed seat 301. A reversing gear 506 is rotatably connected to the inside of the fixed seat 301. The first rack 502 is meshed with the reversing gear 506. A second rack 504 is slidably connected to the inside of the fixed seat 301. The second rack 504 and the first rack 502 are arranged perpendicular to each other. A torsion spring 507 is fixedly connected between the reversing gear 506 and the fixed seat 301. A tooth groove 503 is formed in the side of the connecting rotary block 302. The second rack 504 is meshed with the connecting rotary block 302 through the tooth groove 503.

[0047] In order to separate the pulley 202 from the surface of the slide rail 1 during the cleaning process of the pulley 202 and avoid friction between the two, the connecting rotary block 302 will drive the second rack 504 to slide through the tooth grooves 503 on both sides, and the sliding of the second rack 504 will further drive the first rack 502 set horizontally to slide through the reversing gear 506. The groove 505 on the other side of the first rack 502 will be staggered with the protrusion on the bottom side of the lifting block 501 as the first rack 502 slides. At this time, the lifting block 501 will move toward the top side and The slider 201 is slightly lifted from the slide rail 1 as a whole. At this time, the pulley 202 is separated from the surface of the slide rail 1, so that the pulley 202 will not rub against the slide rail 1 during the rotation cleaning process. After the cleaning of the pulley 202 is completed, the connecting rotary block 302 and the slider 201 are released. The connecting rotary block 302 will return to the vertical state due to the action of the torsion spring 507, and the first rack 502 slides back so that the protrusion on the bottom side of the lifting block 501 slides into the groove 505 on the first rack 502. At this time, the lifting block 501 is lowered, so that the slider 201 returns to the surface of the slide rail 1.

[0048] Specifically, such as Figure 1 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 As shown, the support structure 4 includes an adjusting screw 403, the bottom side of the slide rail 1 is rotatably connected to the adjusting screw 403, the adjusting screw 403 is threadedly connected to a threaded block 404, the side of the slide rail 1 is rotatably connected to a plurality of support rods 401, two adjacent support rods 401 are arranged in an "eight" shape, and the side of the support rod 401 is provided with a limiting groove 402, the threaded block 404 is slidably connected to the support rod 401 through the limiting groove 402, the top side of the threaded block 404 is slidably connected to the slide rail 1, and the thread directions of the two adjacent threaded blocks 404 and the upper part of the corresponding adjusting screw 403 are opposite;

[0049] There are multiple groups of support rods 401 arranged in an "eight" shape on the bottom side of the slide rail 1. The user can rotate the adjustment screw 403 at the end of the slide rail 1 to drive the threaded block 404 on the bottom side of the slide rail 1 to slide. When the threaded block 404 slides, its side will slide in the limit groove 402 on the support rod 401 and drive the support rod 401 to rotate, thereby adjusting the height of the slide rail 1.

[0050] When the present invention is in use, first, the top side of the slide rail 1 is in a diamond structure, and a pulley 202 arranged obliquely is provided on each side of the slider 201 to provide support and sliding effect for the slider 201. Due to the inclined plane structure on both sides of the slide rail 1, it is difficult for large-particle impurities to remain on the slide rail 1 and affect the sliding of the slider 201. At the same time, the two obliquely arranged pulleys 202 slide on the slide rail 1, which can prevent the slider 201 from shifting during the sliding process. The ball 203 arranged between the fixed sleeve 204 and the pulley 202 can reduce the wear of the top side part of the pulley 202 during the rolling process. When it is necessary to clean the slide rail 1 or the slider 201, the user can rotate the connecting rotary block 302 arranged on the fixed seat 301 at the end of the slide rail 1 to the horizontal state, and then slide the slider 201 to abut against the fixed seat 301. At this time, the engaging block 304 arranged on the side of the slider 201 will engage with the card slot 306 on the side of the connecting rotary block 302. With the rotation angle limit of the connecting rotary block 302, the slider 201 can be fixed on the fixed seat 301. When it is necessary to release the slider 201, the user can rotate the release rod 303 on the connecting rotary block 302. At this time, the end of the pushing rod 307 will disengage from the arc-shaped groove on the side of the release rod 303 and slide to one side. At this time, the end of the pushing rod 307 will push the engaging block 304 to release the connection state between the slider 201 and the fixed seat 301. When the slider 201 is connected and fixed to the connecting rotary block 302, since the connecting rotary block 302 rotates, the convex structure in the middle of the connecting rotary block 302 will push the first inclined plane block 608 to slide downward, and then push the end of the ejecting block 610 to extend out of the side of the fixed seat 301 through the inclined side of the first inclined plane block 608. In this way, when the end of the slider 201 abuts against the fixed seat 301, the end of the ejecting block 610 will push the central slide rod 603 arranged in the slider 201. As the central slide rod 603 slides, the end of the connecting column 604 at the end of the pulley 202 will disengage from the positioning groove 611 on the side of the central slide rod 603. At this time, both side ends of the connecting column 604 will engage in the connecting groove 606 inside the worm gear sleeve 602. At this time, the worm gear sleeve 602 and the pulley 202 will rotate synchronously. On the other hand, since the slider 201 abuts against the side of the fixed seat 301, the end of the plugging rod 616 on the side of the fixed seat 301 will slide into the slot 612 at the end of the worm 601. At this time, the user can rotate the rotary cover 607 located on the side of the fixed seat 301. The inner side of the rotary cover 607 meshes with the end of the drive shaft 613. The rotation of the rotary cover 607 will drive the two drive shafts 613 and the plugging rod 616 sliding on the drive shaft 613 to rotate at the same time. Further, the plugging rod 616 will drive the worm 601 to rotate, and the worm 601 will drive the pulley 202 to rotate through the worm gear sleeve 602. By manually controlling the rotation of the pulley 202 arranged at the bottom side of the slider 201, it is convenient to fully clean the impurities that may adhere to the side of the pulley 202.When the slider 201 and the fixed seat 301 are in a connected state, the central slide bar 603 slides due to the push of the ejection block 610. At this time, the raised structure in the middle of the central slide bar 603 moves to the end position of the second inclined surface block 705 and pushes it. The end of the second inclined surface block 705 is a triangular structure. The two oblique sides of the second inclined surface block 705 push the pushing blocks 702 on both sides to the sides respectively, and then push the cleaning scraper 701 toward the adjacent pulley 202 through the fifth spring 703 until the side of the cleaning scraper 701 is aligned with the pulley 202. 02, the side of the pulley 202 is tightly in contact with the user, at this time the user rotates the rotary cover 607 to drive the pulley 202 to rotate to scrape off the impurities attached to the side of the pulley 202, and maintain the sliding smoothness of the slider 201. In order to separate the pulley 202 from the surface of the slide rail 1 during the cleaning process of the pulley 202 to avoid friction between the two, after the connecting rotary block 302 rotates, it will drive the second rack 504 to slide through the tooth grooves 503 on both sides, and the sliding of the second rack 504 will further drive the first rack 502 set horizontally to slide through the reversing gear 506 The groove 505 on the other side of the first rack 502 will be staggered with the protrusion on the bottom side of the lifting block 501 as the first rack 502 slides. At this time, the lifting block 501 will move toward the top side and slightly lift the slider 201 from the slide rail 1. At this time, the pulley 202 will be separated from the surface of the slide rail 1, so that the pulley 202 will not rub against the slide rail 1 during the rotation cleaning process. After the cleaning of the pulley 202 is completed, the connecting rotary block 302 and the slider 201 are released, and the connecting rotary block 302 will return to the vertical state due to the action of the torsion spring 507, and the first rack 502 will return to the vertical state. The sliding movement causes the protrusion on the bottom side of the lifting block 501 to slide into the groove 505 on the first rack 502. At this time, the lifting block 501 is lowered, causing the slider 201 to return to the surface of the slide rail 1. Multiple groups of support rods 401 arranged in an "eight" shape are provided on the bottom side of the slide rail 1. The user can rotate the adjustment screw 403 at the end of the slide rail 1 to drive the threaded block 404 on the bottom side of the slide rail 1 to slide. As the threaded block 404 slides, its side surface slides within the limit groove 402 on the support rod 401 and drives the support rod 401 to rotate, thereby adjusting the height of the slide rail 1.
