[0015] As a further technical solution of the present invention, the side wall of the second brush plate is fixedly connected with a second slider, the second slider is slidably installed inside the dustproof box, and a second spring is installed at the bottom end of the second slider.

[0016] A dust prevention method for a linear guide rail with a dust prevention structure comprises the following steps:

[0017] S1: When working, the guide rail slider slides on the outer wall of the guide rail body, and the movement of the guide rail slider drives the movement of the dust box. At the same time, the air pump is started, and the dust is sucked from the surface of the guide rail body through the dust suction pipe connected to the first connecting pipe, and the sucked impurities are discharged into the dust collection box for storage, and the gas is discharged after being filtered by the filter;

[0018] S2: The movement of the dustproof box drives the movement of the cleaning plate, the first brush plate and the second brush plate, so that the cleaning plate, the first brush plate and the second brush plate contact and clean the surface of the guide rail body;

[0019] S3: When inhaling, the gas inside the airbag is sucked away through the second connecting pipe, so that the side of the airbag close to the guide rail body moves inward and separates from the surface of the guide rail body. At the same time, the movement of the airbag drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the limit plate. When the limit plate moves, the first spring is deformed by force and stores elastic potential energy, and the movement of the limit plate drives the movement of the rack plate. When the rack plate moves to mesh with the gear, it drives the gear to rotate. The rotation of the gear drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the rotation of the ball valve to close the intake pipe.

[0020] S4: The gas flows in the dust suction pipe and drives the wind control plate to rotate. The rotation of the wind control plate drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the reciprocating screw. The rotation of the reciprocating screw drives the first slider to reciprocate for a distance. The movement of the first slider drives the first brush plate to reciprocate laterally on the surface of the guide rail body. When the first brush plate moves, the end of the first brush plate contacts the top of the second brush plate, forcing the second brush plate to move downward. The movement of the second brush plate drives the movement of the second slider, and the elastic potential energy of the second spring causes the second slider to move up and down, so that when the first brush plate reciprocates laterally, the second brush plate reciprocates vertically to clean the surface of the guide rail body.

[0021] S5: When the air intake stops, the elastic potential energy is released by the first spring to move the limit plate to the side close to the airbag, assisting the airbag to reset. Similarly, the ball valve rotates to open the air intake pipe, so that the airbag is inflated when it is reset, so that the airbag and the outer wall of the guide rail body are tightly fitted again to seal and prevent dust.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention sets a dust removal component. When working, the guide rail slider slides on the outer wall of the guide rail body. The movement of the guide rail slider drives the movement of the dust box, and the air pump is started at the same time. The surface of the guide rail body is dusted through the dust suction pipe connected to the first connecting pipe, and the sucked impurities are discharged into the dust box for storage. The gas is discharged after being filtered by the filter. Finally, the impurities in the dust box can be cleaned by removing the maintenance plate, and the linear guide rail is dusted by dust suction through the dust suction pipe, which reduces the space occupied by the current dustproof structure and improves the space utilization efficiency.

[0024] 2. The present invention provides a sealing component. When the device is not working, the airbag is located between the dustproof box and the guide rail body to seal the gap between the two, preventing dust and particles from entering the interior of the guide rail, thereby achieving a dustproof effect.

[0025] 3. Through the setting of the cleaning component, the present invention, when working, the movement of the dustproof box drives the movement of the first brush plate and the second brush plate, and the bristles installed on the outer walls of the first brush plate and the second brush plate contact the outer wall of the guide rail body to clean it, which can effectively remove the attached dust, oil stains and other impurities. When used in conjunction with the dust removal component, the cleaning effect and efficiency of the device can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, in an embodiment of the present invention, a linear guide rail with a dustproof structure includes a guide rail body 1, a guide rail slider 2 is slidably mounted on the outer wall of the guide rail body 1, and a dust removal component is mounted on the side wall of the guide rail slider 2;

[0037] Among them, the dust removal component includes a dust box 3 installed on the side wall of the guide rail slider 2, the inner wall of the dust box 3 is provided with a sealing component and a cleaning component, the interior of the dust box 3 is provided with a first connecting pipe 5, the inner wall of the first connecting pipe 5 is fixedly connected with a dust suction pipe 6, the dust suction pipe 6 is evenly distributed, an air pump 7 is installed at the top of the first connecting pipe 5, a dust box 8 is arranged on one side of the top of the air pump 7, a maintenance plate 9 is arranged above the dust box 8, and a filter 10 is evenly installed on the inner wall of the maintenance plate 9.

[0038] The dustproof box 3 can be installed on both sides or one side of the guide rail slider 2 according to actual needs;

[0039] The air intake port of the air pump 7 is connected to the first connecting pipe 5, and the air exhaust port of the air pump 7 is arranged at the top end of one side of the dust collecting box 8;

[0040] During operation, the guide rail slider 2 slides on the outer wall of the guide rail body 1, and the movement of the guide rail slider 2 drives the movement of the dust box 3, and at the same time, the air pump 7 is started, and the dust is sucked from the surface of the guide rail body 1 through the dust suction pipe 6 connected to the first connecting pipe 5, and the sucked impurities are discharged into the dust box 8 for storage, and the gas is filtered by the filter 10 and then discharged. Finally, the impurities in the dust box 8 can be cleaned by removing the maintenance plate 9;

[0041] The linear guide rail is dusted by suction through the dust suction pipe 6, which reduces the space occupied by the current dust-proof structure and improves the space utilization efficiency.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, a cleaning plate 4 is fixedly mounted on the inner wall of the dustproof box 3 .

[0043] When the dustproof box 3 moves at the top end of the guide rail body 1 , the cleaning plate 4 contacts and cleans the surface of the guide rail body 1 , thereby further improving the dust removal effect on the guide rail body 1 .

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the sealing assembly includes an airbag 11 installed on the inner wall of the first connecting tube 5 , and the inner wall of the airbag 11 is in contact with the outer wall of the guide rail body 1 .

[0045] The airbag 11 is usually made of a wear-resistant and aging-resistant rubber material with good elasticity and sealing performance;

[0046] When the device is not working, the airbag 11 is located between the dustproof box 3 and the guide rail body 1 to seal the gap between the two, preventing dust and particles from entering the interior of the guide rail, thereby achieving a dustproof effect.

[0047] like Figure 5 and Figure 6 As shown, an air intake pipe 13 is fixedly connected to one side of the air bag 11 , a second connecting pipe 12 is fixedly connected to one side of the air intake pipe 13 , and an end of the second connecting pipe 12 away from the air intake pipe 13 is fixedly connected to the first connecting pipe 5 .

[0048] When vacuuming, the gas inside the airbag 11 is sucked away through the second connecting pipe 12, so that the airbag 11 moves inward on the side close to the guide rail body 1, preventing the airbag 11 from fitting tightly against the guide rail body 1 when the dustproof box 3 moves, causing wear on the airbag 11 and affecting its service life and sealing effect.

[0049] like Figure 2 and Figure 6 As shown, two connecting rods 14 are fixedly connected to the inner wall of the airbag 11 , and one end of the two connecting rods 14 away from the airbag 11 is fixedly connected to a limit plate 15 , and a first spring 16 is provided on one side of the two limit plates 15 .

[0050] When the airbag 11 moves inward, it drives the connecting rod 14 to move. The movement of the connecting rod 14 drives the movement of the limit plate 15. When the limit plate 15 moves, the first spring 16 is deformed by force and stores elastic potential energy. When the vacuuming stops, the elastic potential energy is released by the first spring 16 to assist the airbag 11 in resetting, so that the airbag 11 and the outer wall of the guide rail body 1 are tightly fitted again for sealing, thereby preventing dust.

[0051] A one-way valve is installed on the outer wall of the air inlet pipe 13;

[0052] When the airbag 11 is reset, external air is drawn into the airbag 11 through the air inlet pipe 13 .

[0053] like Figure 6 and Figure 7 As shown, a ball valve 20 is rotatably installed inside the intake pipe 13, and the top of the ball valve 20 is fixedly connected to a first rotating shaft 19, and a gear 18 is fixedly installed on the top of the first rotating shaft 19. A rack plate 17 is provided on one side of the gear 18, and the rack plate 17 is fixedly installed at the bottom end of one of the limit plates 15.

[0054] When inhaling, the limit plate 15 moves to the side away from the airbag 11, and the movement of the limit plate 15 drives the movement of the rack plate 17. When the rack plate 17 moves to mesh with the gear 18, it drives the gear 18 to rotate. The rotation of the gear 18 drives the rotation of the first rotating shaft 19. The rotation of the first rotating shaft 19 drives the rotation of the ball valve 20 to close the air inlet pipe 13. External air cannot enter the device from the air inlet pipe 13, preventing external air from being inhaled through the air inlet pipe 13 during vacuuming, thereby affecting the air extraction effect of the airbag 11.

[0055] When the air intake stops, the limit plate 15 moves to the side close to the airbag 11. Similarly, the ball valve 20 rotates to open the air inlet pipe 13, so that the airbag 11 is inflated when it is reset to ensure the sealing and dustproof effect.

[0056] like Figures 1 to 5 and Figure 8 As shown, the cleaning assembly includes a first brush plate 27 installed on the inner wall of the dustproof box 3, and second brush plates 28 are provided at both ends of the first brush plate 27. The first brush plate 27 and the second brush plate 28 are both arranged on the outer wall of the guide rail body 1.

[0057] During operation, the movement of the dustproof box 3 drives the movement of the first brush plate 27 and the second brush plate 28. The bristles installed on the outer walls of the first brush plate 27 and the second brush plate 28 contact the outer wall of the guide rail body 1 to clean it, which can effectively remove the attached dust, oil stains and other impurities. When used in conjunction with the dust removal component, the cleaning effect and efficiency of the device can be further improved.

[0058] like Figures 1 to 5 and Figure 8 As shown, the top of the first brush plate 27 is fixedly connected to the first slider 26, and the first slider 26 is slidably installed inside the dustproof box 3. The internal thread of the first slider 26 is connected to the reciprocating screw 25, and one end of the reciprocating screw 25 is fixedly connected to the second bevel gear 24, and one side of the second bevel gear 24 is meshingly connected to the first bevel gear 23. The side wall of the first bevel gear 23 is fixedly connected to the second rotating shaft 22, and one end of the second rotating shaft 22 is fixedly connected to the wind control plate 21, and the wind control plate 21 is arranged inside the dust suction pipe 6.

[0059] During vacuuming, the gas flows in the vacuum tube 6 to drive the wind control plate 21 to rotate, and the rotation of the wind control plate 21 drives the rotation of the second rotating shaft 22, and the rotation of the second rotating shaft 22 drives the rotation of the first bevel gear 23, and the rotation of the first bevel gear 23 drives the rotation of the second bevel gear 24, and the rotation of the second bevel gear 24 drives the rotation of the reciprocating screw 25, and the rotation of the reciprocating screw 25 drives the first slider 26 to reciprocate a certain distance, and the movement of the first slider 26 drives the first brush plate 27 to reciprocate laterally on the surface of the guide rail body 1 to clean the top of the guide rail body 1 and improve the cleaning effect.

[0060] like Figure 8 As shown, the side wall of the second brush plate 28 is fixedly connected with a second slider 29 , and the second slider 29 is slidably installed inside the dustproof box 3 , and a second spring 30 is installed at the bottom end of the second slider 29 .

[0061] Both ends of the first brush plate 27 are configured to be wedge-shaped;

[0062] When the first brush plate 27 moves, the end of the first brush plate 27 contacts the top of the second brush plate 28, forcing the second brush plate 28 to move downward. The movement of the second brush plate 28 drives the movement of the second slider 29, and the elastic potential energy of the second spring 30 causes the second slider 29 to move up and down, so that when the first brush plate 27 moves back and forth horizontally, the second brush plate 28 moves back and forth vertically, so as to ensure the comprehensiveness and cleaning effect of the surface of the guide rail body 1.

[0063] A dust prevention method for a linear guide rail with a dust prevention structure comprises the following steps:

[0064] S1: During operation, the guide rail slider 2 slides on the outer wall of the guide rail body 1, and the movement of the guide rail slider 2 drives the movement of the dust box 3. At the same time, the air pump 7 is started, and the dust is sucked from the surface of the guide rail body 1 through the dust suction pipe 6 connected to the first connecting pipe 5, and the sucked impurities are discharged into the dust collecting box 8 for storage, and the gas is discharged after being filtered by the filter screen 10;

[0065] S2: The movement of the dust box 3 drives the movement of the cleaning plate 4, the first brush plate 27 and the second brush plate 28, which contact and clean the surface of the guide rail body 1;

[0066] S3: When inhaling, the gas inside the airbag 11 is sucked away through the second connecting tube 12, so that the side of the airbag 11 close to the guide rail body 1 moves inward and separates from the surface of the guide rail body 1. At the same time, the movement of the airbag 11 drives the movement of the connecting rod 14, and the movement of the connecting rod 14 drives the movement of the limit plate 15. When the limit plate 15 moves, the first spring 16 is deformed by force and stores elastic potential energy, and the movement of the limit plate 15 drives the movement of the rack plate 17. When the rack plate 17 moves to mesh with the gear 18, it drives the gear 18 to rotate. The rotation of the gear 18 drives the rotation of the first rotating shaft 19. The rotation of the first rotating shaft 19 drives the rotation of the ball valve 20 to close the intake pipe 13.

[0067] S4: The gas flows in the dust suction pipe 6 to drive the wind control plate 21 to rotate, and the rotation of the wind control plate 21 drives the rotation of the second rotating shaft 22, and the rotation of the second rotating shaft 22 drives the rotation of the first bevel gear 23, and the rotation of the first bevel gear 23 drives the rotation of the second bevel gear 24, and the rotation of the second bevel gear 24 drives the rotation of the reciprocating screw 25, and the rotation of the reciprocating screw 25 drives the first slider 26 to reciprocate for a distance, and the movement of the first slider 26 drives the first brush plate 27 to reciprocate laterally on the surface of the guide rail body 1. When the first brush plate 27 moves, the end of the first brush plate 27 contacts the top of the second brush plate 28, forcing the second brush plate 28 to move downward, and the movement of the second brush plate 28 drives the movement of the second slider 29, and the elastic potential energy of the second spring 30 causes the second slider 29 to move up and down, so that when the first brush plate 27 reciprocates laterally, the second brush plate 28 reciprocates vertically, thereby cleaning the surface of the guide rail body 1;

[0068] S5: When the air intake stops, the elastic potential energy is released by the first spring 16 to move the limit plate 15 to the side close to the airbag 11, and the airbag 11 is assisted to reset. Similarly, the ball valve 20 rotates to open the air intake pipe 13, so that the airbag 11 is inflated when it is reset, so that the airbag 11 and the outer wall of the guide rail body 1 are tightly fitted again to seal and prevent dust.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

When the rack plate (17) moves to mesh with the gear (18), it drives the gear (18) to rotate. The rotation of the gear (18) drives the rotation of the first rotating shaft (19). The rotation of the first rotating shaft (19) drives the rotation of the ball valve (20) to close the air intake pipe (13); S4: The gas flows in the dust suction pipe (6) to drive the wind control plate (21) to rotate, the rotation of the wind control plate (21) drives the second rotating shaft (22) to rotate, the rotation of the second rotating shaft (22) drives the first bevel gear (23) to rotate, the rotation of the first bevel gear (23) drives the second bevel gear (24) to rotate, the rotation of the second bevel gear (24) drives the reciprocating screw (25) to rotate, the rotation of the reciprocating screw (25) drives the first slider (26) to reciprocate for a distance, and the movement of the first slider (26) The first brush plate (27) is moved to reciprocate laterally on the surface of the guide rail body (1). When the first brush plate (27) moves, the end of the first brush plate (27) contacts the top of the second brush plate (28) to force the second brush plate (28) to move downward. The movement of the second brush plate (28) drives the movement of the second slider (29), and the elastic potential energy of the second spring (30) causes the second slider (29) to move up and down, so that when the first brush plate (27) reciprocates laterally, the second brush plate (28) reciprocates vertically, thereby cleaning the surface of the guide rail body (1); S5: When the air intake stops, the elastic potential energy is released by the first spring (16) to move the limit plate (15) toward the side close to the airbag (11), thereby assisting the airbag (11) to reset. Similarly, the ball valve (20) rotates to open the air inlet pipe (13), so that the airbag (11) is inflated when reset, and the airbag (11) and the outer wall of the guide rail body (1) are tightly fitted again to seal and prevent dust.
