When the slider 2 slides horizontally on the upper end of the linear guide 1, when the primary sealing sheet 24 contacts the side wall of the linear guide 1, the dust on the surface of the linear guide 1 can be scraped off, and the inside of the slider 2 is sealed to avoid contamination and damage to the internal components of the slider 2;

[0041] A strengthening sealing component is provided to strengthen the sealing effect on the basis of the sealing of the initial sealing sheet 24. The strengthening sealing component is movably arranged in the sealing connection box 3 through the adjusting component. The strengthening sealing component includes a flat support frame 6 and two vertical support frames 5.

The adjusting component includes an air inlet groove 11. A guide installation groove 4 is provided in the sealing connection box 3. The vertical support frame 5 is horizontally arranged at the upper end of the guide installation groove 4. Two matching grooves 7 are symmetrically arranged on both sides of the vertical support frame 5. The two flat support frames 6 are vertically symmetrically arranged on both sides of the vertical support frame 5. The vertical support frame 5 and the vertical support frame 5 are connected to each other. The upper end of the linear guide rail 1 is flush, the flat support frame 6 corresponds vertically to the side of the linear guide rail 1, the vertical sealing sheet 8 and the horizontal sealing sheet 9 are respectively in contact with the side walls of the linear guide rail 1, and when the vertical sealing sheet 8 and the horizontal sealing sheet 9 are in contact with the linear guide rail 1, there is a gap between the vertical support frame 5 and the flat support frame 6 and the linear guide rail 1, and sealing compensation blocks 10 are provided on both sides of the lower end of the horizontal sealing sheet 9, and one side of the sealing compensation block 10 passes over one side of the vertical support frame 5 and is in contact with the vertical sealing sheet 8. When the initial sealing interception of the initial sealing sheet 24 fails, the vertical sealing sheets 8 and the horizontal sealing sheets 9 on both sides of the vertical support frame 5 and the flat support frame 6 can be strengthened with double sealing, so that when the sealing connection box 3 performs a sealing operation on the slider 2, it has a triple sealing effect;

[0043] In this embodiment, when the slider 2 slides horizontally above the linear guide rail 1, a layer of sealing is performed under the action of the initial sealing sheet 24 to prevent dust and dirt above the linear guide rail 1 from entering the slider 2, and then the sealing effect is further improved with the auxiliary reinforcement of the four vertical sealing sheets 8 and the two horizontal sealing sheets 9.

[0044] Embodiment 2

[0045] On the basis of the first embodiment, the positions of the two vertical support frames 5 and the horizontal support frame 6 are adaptively adjusted, the air inlet groove 11 is U-shaped and opened in the sealing connection box 3, and a gas joint 12 is provided on one side of the air inlet groove 11 through the sealing connection box 3, and a plurality of piston grooves 13 are horizontally and symmetrically opened on one side of the air inlet groove 11 close to the vertical support frame 5, and an adjusting push rod 14 is horizontally provided on one side of the vertical support frame 5 close to the piston groove 13, and one side of the plurality of adjusting push rods 14 is respectively movably penetrated through one side of the guide installation groove 4, and is inserted into the piston groove 13 and sleeved with an adjusting piston 30, and the gas joint 12 can be connected to the high-pressure gas connected by the hose, and when the high-pressure gas is injected into the air inlet groove 11, the adjusting piston 30 can push the adjusting piston 30 and the vertical support frame 5 to move;

[0046] A first shunt groove 15 is provided on the inclined surface of the second linkage block 19 in the vertical support frame 5, and a valve groove is provided at the center of the adjusting push rod 14 on one side of the vertical support frame 5 to connect the air inlet groove 11 and the first shunt groove 15. A one-way valve is horizontally provided in the valve groove, and the one-way valve includes a valve body, and air holes are provided on both sides of the valve body. A sealing ball 31 and a valve spring 32 are respectively provided on one side of the two air holes in the valve body, and one side of the sealing ball 31 and the valve spring 32 are in contact. When the adjusting piston 30 pushes the vertical support frame 5 to move, the vertical support frame 5 can push the flat support frame 6 to descend through the inclined surface of the second linkage block 19 and the inclined surface of the first linkage block 18, so that the vertical support frame 5 and the flat support frame 6 are respectively close to the linear guide rail 1, so that the vertical sealing sheet 8 and the horizontal sealing sheet 9 are better sealed and fitted with the linear guide rail 1;

[0047] A second diverter groove 20 is provided on one side of the flat support frame 6 close to the linear guide rail 1, and docking grooves 21 are provided on both sides of the second diverter groove 20 respectively penetrating the inclined surface of the first linkage block 18. The first diverter groove 15 and the docking groove 21 are arranged opposite to each other, and the relative sliding of the second linkage block 19 and the first linkage block 18 always maintains the gas connection between the first diverter groove 15 and the docking groove 21. A plurality of second impact holes 22 are provided in the second diverter groove 20 penetrating the flat support frame 6, and a plurality of first impact holes 16 are provided in the first diverter groove 15 penetrating one side of the vertical support frame 5. The second impact holes 22 and the first impact holes 16 point to the linear guide rail 1 respectively, and the apertures of the second impact holes 22 and the first impact holes 16 on one side close to the linear guide rail 1 are smaller than the apertures on the other side. There is a track splicing seam 34 when the linear guide rail 1 is spliced ​​and installed. When the sealing connection box 3 passes through the track splicing seam 34, high-pressure blowing can be performed to clean pollutants.

[0048] In this embodiment, a position sensor is arranged at the position of the track joint 34 of the linear guide rail 1. When the slider 2 is about to reach the position of the track joint 34, high-pressure air is injected into the air inlet groove 11. The high-pressure air pushes the sealing ball 31 and enters the first diverter groove 15. At this time, there is still a gap between the vertical support frame 5 and the flat support frame 6 and the linear guide rail 1. The vertical sealing sheet 8 and the horizontal sealing sheet 9 are in pressurized contact with the linear guide rail 1, but do not affect the normal sliding of the slider 2. A part of the high-pressure gas entering the first diverter groove 15 is blown from the first impact hole 16 to the side of the track joint 34 of the linear guide rail 1, and the other part enters the flat support frame 6 through the first linkage block 18 and the second linkage block 19, and is blown from the second impact hole 22 to the top of the track joint 34 to clean the dust accumulation and improve the cleanliness of the slider 2.

[0049] Another one-way valve can be set on the gas connector 12. During normal use, a certain amount of high-pressure gas is introduced into the air inlet groove 11. At this time, the high-pressure gas will not push the sealing ball 31, but will push the vertical support frame 5 and the horizontal support frame 6 closer to the linear guide rail 1, thereby improving the contact sealing effect. When the cleaning function of the track joint 34 is required, higher-pressure gas is introduced.

[0050] Embodiment 3

[0051] On the basis of the second embodiment, a bottom sealing assembly is provided to seal the bottom of the slider 2 and the sealing connection box 3. The bottom sealing assembly includes two bottom sealing boxes 26. The bottom sealing boxes 26 are installed at the lower ends of the same sides of the two sealing connection boxes 3 by bolts. The lower end centers of the two vertical support frames 5 of the two sealing connection boxes 3 are vertically provided with positioning rods 25. The upper ends of the two bottom sealing boxes 26 are symmetrically provided with two positioning grooves 36. The lower ends of the two positioning rods 25 are movably inserted into the two positioning grooves 36 respectively. The two sides of the two bottom sealing boxes 26 are respectively fitted with the compression pieces 23 of the two sealing connection boxes 3 by bolts. The bottom sealing boxes 26 are horizontally provided with bottom sealing strips 27 on the side close to the linear guide rail 1. One side of the bottom sealing strips 27 is fitted and contacted with the linear guide rail 1. The lower ends of the two sides of the two initial sealing pieces 24 are respectively squeezed and contacted with one side of the upper ends of the two bottom sealing pieces 27 for sealing. The bottom sealing box 26 cooperates with the compression piece 23 for simple and convenient installation and operation. When in use, the bottom of the slider 2 and the sealing connection box 3 can be sealed to prevent dirt in the air from entering from below.

[0052] The bottom sealing box 26 is provided with a receiving groove 28 on one side of the positioning groove 36, and a pressure relief groove 35 is provided in the bottom sealing box 26 between the two receiving grooves 28 in a horizontal manner. An exhaust window is provided in the center of the lower end of the pressure relief groove 35 and penetrates the bottom sealing box 26, and a filter cloth 29 is horizontally inserted in the exhaust window. After the first impact hole 16 and the second impact hole 22 blow back the dust in the track joint 34, the dust-containing gas enters the pressure relief groove 35 from the receiving groove 28 for pressure relief, and finally the gas is discharged from the filter port of the filter cloth 29. Since there is less dust in the track joint 34, the dust is first retained in the pressure relief groove 35, and the bottom sealing box 26 can be disassembled and cleaned regularly. The filter cloth 29 can prevent the dust in the pressure relief groove 35 from being discharged, and can also prevent external dust from entering.

[0053] In addition, an oil storage tank 33 may be provided at the upper end of the sealing connection box 3 , and one side of the oil storage tank 33 is connected to the slider 2 , so as to facilitate the subsequent oil replenishment operation of the slider 2 .
