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 making creative efforts are within the scope of protection of the present invention.

[0036] In a preferred embodiment, the lubricating assembly 4 includes a limiting rail 401, an inner cavity of the limiting rail 401 is provided with a storage groove 402, an inner cavity of the limiting rail 401 is provided with a release groove 403, an inner wall of the release groove 403 is fixedly assembled with a limiting rod 404, an outer wall of the limiting rod 404 is movably sleeved with a movable plate 405, an outer wall of the limiting rod 404 is movably sleeved with a return spring 406, an outer wall of the movable plate 405 is fixedly assembled with a blocking plate 407, an inner cavity of the storage groove 402 is movably sleeved with a movable plug 408, the bottom of the movable plug 408 is rotatably connected to a rotating plate 409, and the bottom of the movable plug 408 is fixedly assembled with a limiting frame 4010;

[0037] In the above structure, by providing the storage groove 402 and the release groove 403 in the inner cavity of the limit rail 401, and by injecting grease into the inner cavities of the release groove 403 and the storage groove 402, in the process of the movable plug 408 moving downward along the inner wall of the limit rail 401, the grease in the inner cavities of the storage groove 402 and the release groove 403 can be squeezed, so that the grease pushes the movement of the movable plate 405 and the sealing plate 407, so that the movable plate 405 moves toward the outside of the limit rail 401. At this time, the grease in the inner cavity of the limit rail 401 will move outward from the inner cavity of the release groove 403, so that the grease contacts the outer wall of the limit rail 401, thereby realizing lubrication of the outer wall of the limit rail 401 under the action of the grease, ensuring that the movable seat 5 can operate stably on the outer wall of the limit rail 401.

[0038] In a preferred embodiment, a fixing rod 4011 is fixedly mounted on the top of the movable plug 408, a piston plate 4012 is fixedly mounted on the top of the fixing rod 4011, an air guide cylinder 4013 is mounted on the top of the column body 3, a connecting pipe 4014 is fixedly mounted on the top of the air guide cylinder 4013, a driving cylinder 4015 is fixedly mounted on the outer wall of the column body 3, a driving plate 4016 is movably sleeved on the inner cavity of the driving cylinder 4015, a driving rod 4017 is fixedly mounted on the top of the driving plate 4016, an electromagnet 4018 is fixedly mounted on the top of the driving rod 4017, a permanent magnet 4019 is fixedly mounted on the outer wall of the movable seat 5, and an oiling screw 4020 is threadedly connected to the outer wall of the limiting rail 401.

[0039] In the above structure, by providing the driving cylinder 4015 and the driving plate 4016 provided in the inner cavity of the driving cylinder 4015, when the outer wall of the limit rail 401 needs to be lubricated, the position of the movable seat 5 is adjusted to the middle of the limit rail 401, and the electromagnet 4018 is energized to generate magnetism. At this time, the electromagnet 4018 will adsorb the permanent magnet 4019, so that the driving rod 4017 and the movable seat 5 can move synchronously. At this time, when the movable seat 5 moves downward, it will drive the driving rod 4017 to move synchronously with the movable seat 5. The moving rod 4017 and the driving plate 4016 move downward, thereby squeezing the air in the inner cavity of the driving cylinder 4015, so that the air in the inner cavity of the driving cylinder 4015 enters the air guide cylinder 4013 along the connecting tube 4014, thereby driving the piston plate 4012 and the movable plug 408 in the air guide cylinder 4013, so that the movable plug 408 moves downward along the inner cavity of the limiting rail 401, thereby squeezing the grease in the inner cavity of the limiting rail 401, causing the grease to overflow and then contact the outer wall of the limiting rail 401.

[0040] In a preferred embodiment, the outer diameter of the movable plug 408 matches the inner diameter of the storage tank 402 , the outer ends of the return spring 406 contact the outer wall of the movable plate 405 and the inner wall of the release tank 403 , respectively, and the return spring 406 is made of high-carbon steel. The downward rotation angle of the rotating plate 409 is thirty degrees.

[0041] In the above structure, by setting the movable plug 408 in the inner cavity of the limit rail 401, when the movable plug 408 moves downward, the rotating plate 409 will fit against the bottom of the movable plug 408, thereby squeezing the grease. When the movable plug 408 moves upward along the limit rail 401, the rotating plate 409 will rotate downward under the action of gravity. At this time, with the movement of the movable plug 408, the grease of the horizontal base 1 in the inner cavity of the limit rail 401 will not be drawn upward, ensuring that the grease in the limit rail 401 can be squeezed out during the downward movement of the movable plug 408, and the grease will not be affected by the upward movement of the movable plug 408, so that the grease can better lubricate the outer wall of the limit rail 401.

[0042] In a preferred embodiment, the outer diameter of the piston plate 4012 matches the inner diameter of the gas cylinder 4013. The ends of the connecting tube 4014 are connected to the gas cylinder 4013 and the driving cylinder 4015, respectively. The connecting tube 4014 is made of natural rubber. There are two driving cylinders 4015, which are respectively installed on both sides of the outer wall of the column body 3.

[0043] In the above structure, the driving cylinder 4015 is connected to the gas cylinder 4013 under the action of the connecting tube 4014. After the electromagnet 4018 is energized, it can attract the permanent magnet 4019, so that the driving rod 4017 can move with the up and down movement of the movable seat 5, thereby realizing the driving of the driving plate 4016. When the movable seat 5 moves downward, it can squeeze the gas in the inner cavity of the driving cylinder 4015, so that the gas in the driving cylinder 4015 will enter the gas cylinder 4013 along the connecting tube 4014, thereby driving the piston plate 4012 in the gas cylinder 4013, so that the piston plate 4012 moves downward along the inner wall of the gas cylinder 4013, thereby realizing the driving of the movable plug 408 and squeezing the grease in the limit rail 401.

[0044] In a preferred embodiment, the oil discharge assembly 6 includes a fixed tube 601, an oil storage tube 602 is fixedly mounted on the outer wall of the fixed tube 601, an oil storage cylinder 603 is fixedly mounted on the bottom of the oil storage tube 602, a release tube 604 is fixedly mounted on the outer wall of the oil storage cylinder 603, a support plate 605 is mounted on the outer wall of the column body 3, a movable rod 606 is movably sleeved on the inner cavity of the fixed tube 601, a movable plug 607 is fixedly mounted on the top of the movable rod 606, and a lifting plug 608 is fixedly mounted on the bottom of the movable rod 606;

[0045] In the above structure, the fixed tube 601 is provided, and both ends of the fixed tube 601 are respectively connected to the gas guide cylinder 4013, so that the gas in the driving cylinder 4015 can enter the fixed tube 601 along the limit rod 404, thereby allowing the gas to enter the fixed tube 601. At this time, the gas can drive the movable plug 607 in the inner cavity of the fixed tube 601, so that the movable plug 607 moves downward along the inner cavity of the fixed tube 601, thereby pushing the lifting plug 608. Under the action of the lifting plug 608, the grease in the oil storage tube 602 and the oil storage cylinder 603 is squeezed into the release tube 604, and released to the bottom of the column body 3 along the release tube 604, so as to lubricate the contact track between the longitudinal base 2 and the column body 3, thereby ensuring the stable operation of the column body 3.

[0046] In a preferred embodiment: the bottom of the lifting plug 608 is rotatably connected to the rotating plate 409, the bottom of the lifting plug 608 is fixedly assembled with a limiting frame 4010, and the outer wall diameter of the movable plug 607 matches the inner wall diameter of the fixed tube 601;

[0047] In the above structure, by providing the lifting plug 608 in the inner cavity of the oil storage tube 602, when the lifting plug 608 moves downward along with the movable plug 607, the rotating plate 409 will similarly fit the bottom of the lifting plug 608 to squeeze the grease, so that the grease is released outward through the release tube 604. Subsequently, when the movable plug 607 moves upward, the rotating plate 409 will rotate downward, thereby preventing the lifting plug 608 from sucking the grease in the inner cavity of the oil storage cylinder 603 upward when it moves upward.

[0048] In a preferred embodiment: the outer wall of the oil reservoir 603 is threadedly connected to the oil filling screw 4020, and the outer wall diameter of the lifting plug 608 is equal to the inner wall diameter of the oil reservoir 603;

[0049] In the above structure, by providing the oil filling screw 4020 on the outer wall of the oil storage barrel 603 and the limiting rail 401, and by removing the oil filling screw 4020 from the outer wall of the oil storage barrel 603 and the limiting rail 401 respectively, grease is injected into the inner cavity of the oil storage barrel 603 and the limiting rail 401 respectively, and when injecting grease, the movable plug 408 and the lifting plug 608 are respectively located at the top of the limiting rail 401 and the oil storage pipe 602, so that there is enough space in the storage tank 402 and the oil storage pipe 602 to inject grease.

[0050] In a preferred embodiment, the inner volume of the driving cylinder 4015 is larger than the sum of the inner volumes of the gas cylinder 4013 and the oil storage tube 602. The outer wall of the gas cylinder 4013 is connected to the outer wall of the fixed tube 601, and the inner cavity of the gas cylinder 4013 is in communication with the inner cavity of the fixed tube 601.

[0051] In the above structure, through the driving cylinder 4015 set on the outer wall of the column body 3, when the outer wall of the limit rail 401 needs to be lubricated, the movement trajectory of the movable seat 5 starts from the middle of the limit rail 401 and moves downward. After the bottom of the movable seat 5 contacts the top of the column body 3, the movable seat 5 moves upward. After the movable seat 5 moves upward to the middle of the limit rail 401, the entire grease extrusion action is completed. At this time, the electromagnet 4018 stops supplying power, and the electromagnet 4018 is disconnected from the permanent magnet 4019. During the entire process of extruding grease, the blocking plate 407 will not affect the movement of the movable seat 5.

[0052] In a preferred embodiment, the outer wall shape of the limiting rail 401 matches the outer wall shape of the movable base 5, the piston plate 4012 is made of natural rubber, and the inner wall diameter of the storage groove 402 is larger than the inner wall diameter of the release groove 403;

[0053] In the above structure, the limiting rail 401 is provided on the outer wall of the column body 3, so that the movable seat 5 can move along the outer wall of the limiting rail 401. After the grease in the inner cavity of the limiting rail 401 is squeezed out, it can contact the outer wall of the limiting rail 401. Then, as the movable seat 5 moves, the lubrication is fully applied to the outer wall of the limiting rail 401 during the entire operation of the movable seat 5 along the limiting rail 401, thereby ensuring a better lubrication effect on the outer wall of the limiting rail 401.

[0054] Working principle: during the use of the above-mentioned device, when the device needs to be lubricated regularly, the position of the movable seat 5 is adjusted to the middle of the limit rail 401, and then the electromagnet 4018 is powered to increase the magnetic force of the electromagnet 4018. After the magnetic force of the electromagnet 4018 increases, the electromagnet 4018 is synchronized with the permanent magnet 4019. At this time, the movable seat 5 is in the middle position of the limit rail 401, and then the movable seat 5 is moved downward from the middle of the limit rail 401. As the movable seat 5 moves downward, the permanent magnet 4019 is driven to move downward. When the permanent magnet 4019 moves downward, it drives the electromagnet 4018 and the driving rod 4017 to move downward, thereby pushing the movement of the driving plate 4016, and the driving cylinder 4015. The gas in the inner cavity is squeezed, so that the gas enters the connecting pipe 4014 from the driving cylinder 4015, and enters the gas guide cylinder 4013 along the connecting pipe 4014, driving the piston plate 4012 in the inner cavity of the gas guide cylinder 4013, thereby pushing the movable plug 408 downward under the action of the piston plate 4012 and the fixing rod 4011, and the grease in the inner cavity of the limit rail 401 is squeezed by the movable plug 408, and the blocking plate 407 is pushed to move under the action of the grease, so that the blocking plate 407 moves outward. At this time, the grease in the inner cavity of the storage groove 402 and the release groove 403 will be squeezed out, so that the grease is released to the outer wall of the limit rail 401, and the air in the inner cavity of the connecting pipe 4014 is released to the gas guide cylinder After entering 4013, it will enter the fixed tube 601 and drive the movable plug 607 and the lifting plug 608, so that the grease in the inner cavity of the oil storage tube 602 and the oil storage cylinder 603 is squeezed into the release tube 604 and released along the release tube 604 to the outer wall of the sliding seat 7, which plays a role in lubricating the sliding seat 7 and the top of the longitudinal base 2. In the process of squeezing the grease, the moving seat 5 moves downward from the middle of the limit rail 401 to the top of the limit rail 401, completing the lubrication of the outer wall of the limit rail 401 and the outer wall of the sliding seat 7, and then the moving seat 5 moves upward along the outer wall of the limit rail 401. When the moving seat 5 moves upward, the driving cylinder 4015 will back-pump the gas in the gas guide cylinder 4013 and the inner cavity of the fixed tube 601, As a result, the movable plug 408 and the lifting plug 608 move upward along the inner cavity of the storage tank 402 and the oil storage tube 602 respectively, and in the process of the lifting plug 608 and the movable plug 408 moving upward, the grease in the inner cavity of the storage tank 402 and the oil storage tube 602 will not be extracted upward, completing the entire grease squeezing action. At this time, the movable seat 5 moves upward from the bottom of the limit rail 401 to the middle section of the limit rail 401, and then stops supplying power to the electromagnet 4018, so that the electromagnet 4018 and the permanent magnet 4019 are disconnected. At this time, the movable seat 5 can move up and down normally, and after the sealing plate 407 completes the release of the grease, the movable plug 408 moves upward, and the effect of the air pressure on the sealing plate 407 will be reduced.The blocking plate 407 will be attached to the outer wall of the limit rail 401 under the action of the return spring 406, and will not affect the normal movement of the movable seat 5. After the electromagnet 4018 and the permanent magnet 4019 are disconnected, the movable seat 5 can move up and down normally. The grease on the outer wall of the limit rail 401 is evenly applied to ensure the normal and stable operation of the column body 3, so that the outer wall of the limit rail 401 and the outer wall of the sliding seat 7 are well lubricated.
