Description

Technical Field

[0001] This utility model relates to the field of slider structure technology, specifically a self-lubricating slider with an improved structure. Background Technology

[0002] Self-lubricating sliders perform exceptionally well in applications requiring low maintenance, high cleanliness, and corrosion resistance, and are widely used in industries such as food processing, textile machinery, and semiconductor manufacturing.

[0003] Self-lubricating sliders often have an oil reservoir directly on the slider body, allowing the oil to flow onto the guide rail for lubrication as the slider moves. This results in high oil consumption and waste, affecting the self-lubricating effect and requiring repeated replenishment of lubricating oil. Based on this, we propose a new type of self-lubricating slider with an improved structure. Utility Model Content

[0004] The purpose of this invention is to provide a self-lubricating slider with an improved structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating slider with an improved structure, comprising a slider body, a first lubricating shell and a second lubricating shell fixed on both sides of the slider body respectively, a rolling limiting cavity provided inside the first lubricating shell and the second lubricating shell, lubricating balls evenly distributed inside the rolling limiting cavity, a fixed base installed at the top of the first lubricating shell and the second lubricating shell, a drive seat provided on one side of the fixed base, a telescopic block and a spring evenly connected between the fixed base and the drive seat, an oil cotton body in contact with the lubricating balls provided inside the fixed base, an oil storage box installed at the top of the fixed base, an oil passage pipe evenly provided between the oil storage box and the oil cotton body, mounting strips welded to both ends of the fixed base, mounting slots matching the mounting strips provided inside the first lubricating shell and the second lubricating shell, a locking airbag provided at one end of the mounting strip, a locking hole matching the locking airbag provided on the mounting slot, and an air guide pipe connected to the locking airbag.

[0006] Preferably, the first lubricating shell and the second lubricating shell are symmetrically distributed about the vertical center line of the slider body.

[0007] Preferably, both ends of the top of the slider body are provided with external screw holes.

[0008] Preferably, the rolling limiting cavity is provided with an oil distribution hole matching the lubrication ball on the side near the slider body.

[0009] Preferably, the outer wall of the lubricating ball and the inner wall of the rolling limiting cavity are both provided with an epoxy ceramic wear-resistant coating.

[0010] Preferably, the spring is mounted on the telescopic block, and the oil-cotton body is made of high-density fiber.

[0011] Preferably, the top of the oil storage box is provided with an oil filling port, and a sealing plug is snapped onto the oil filling port.

[0012] Preferably, a valve is installed at the top of the air duct to facilitate the opening and closing control of the air duct.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By installing oil cotton bodies, the device optimizes its performance. The lubricating oil inside the oil storage box will soak into the oil cotton body through the oil pipe. Then, the slider body slides on the corresponding guide rail and drives the lubricating balls to contact the outer wall of the guide rail. During this process, the lubricating balls will pass through the oil cotton body and carry the oil to the outer wall of the guide rail. Compared with the ordinary method of directly adding liquid lubricating oil to the ball structure, it achieves the advantages of providing a stable oil supply, extending the maintenance interval, and avoiding oil waste. At the same time, by uniformly connecting the telescopic block and spring between the fixed base and the drive base, the elastic telescopic structure is used to apply elastic pressure to the drive base, so that the oil cotton body fixed on the drive base presses the lubricating balls towards the guide rail. This pressure is beneficial for the oil inside the oil cotton body to be distributed to the lubricating balls, further optimizing the self-lubricating effect.

[0015] (2) By setting up mounting strips, the device optimizes its structure. Users can use the positioning and insertion structure between the mounting strips on the fixed base and the corresponding mounting slots inside the first and second lubrication shells to achieve the positioning and assembly of the fixed base with oil supply structure such as the oil reservoir box inside the corresponding first and second lubrication shells. Then, users can open the pipe valve and inflate the locking airbag on the mounting strip through the air tube with a syringe to make it expand and lock into the locking hole of the mounting slot. The locking airbag and the locking hole can be locked in the horizontal direction to lock the vertically set mounting slot and mounting strip. This not only improves the firmness of the fixed base with oil supply structure such as the oil reservoir box when it is installed on the corresponding first and second lubrication shells, but also makes it easy to release air for disassembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model is provided: a self-lubricating slider with an improved structure, including a slider body 3, a first lubricating shell 1 and a second lubricating shell 2 are fixed on both sides of the slider body 3 respectively, and a rolling limiting cavity 20 is provided inside the first lubricating shell 1 and the second lubricating shell 2, and lubricating balls 11 are evenly distributed inside the rolling limiting cavity 20.

[0024] A fixed base 6 is installed at the top of the interior of both the first lubrication shell 1 and the second lubrication shell 2, and a drive seat 8 is provided on one side of the fixed base 6.

[0025] Telescopic blocks 10 and springs 7 are evenly connected between the fixed base 6 and the drive base 8. The fixed base 6 is provided with an oil cotton body 9 that is in contact with the lubricating balls 11.

[0026] An oil storage box 5 is installed on the top of the fixed base 6, and oil passages 14 are evenly arranged between the oil storage box 5 and the oil cotton body 9.

[0027] During use, the lubricating oil inside the oil reservoir 5 will soak into the oil cotton body 9 through the oil pipe 14. As the slider body 3 slides on the corresponding guide rail and drives the lubricating balls 11 to contact the outer wall of the guide rail, the lubricating balls 11 will pass through the oil cotton body 9 in sequence, carrying the oil to the outer wall of the guide rail. Compared with the ordinary method of directly adding liquid lubricating oil to the ball structure, this method provides the advantages of providing a stable oil supply, extending the maintenance interval, and avoiding oil waste. At the same time, by using the elastic telescopic structure composed of telescopic blocks 10 and springs 7 evenly connected between the fixed base 6 and the drive base 8, elastic pressure is applied to the drive base 8, causing the oil cotton body 9 fixed on the drive base 8 to press the lubricating balls 11 towards the guide rail. This pressure helps the oil inside the oil cotton body 9 to be distributed onto the lubricating balls 11, further optimizing the self-lubricating effect.

[0028] Both ends of the fixed base 6 are welded with mounting strips 16. The first lubrication shell 1 and the second lubrication shell 2 are provided with mounting slots 15 that match the mounting strips 16. One end of the mounting strip 16 is provided with a locking airbag 18. The mounting slot 15 is provided with a locking hole 17 that matches the locking airbag 18. The locking airbag 18 is connected with an air guide tube 12.

[0029] A valve 13 is installed at the top of the air duct 12 to facilitate the opening and closing control of the air duct 12.

[0030] In use, the user can use the positioning and insertion structure between the mounting strip 16 on the fixed base 6 and the corresponding mounting slot 15 inside the first lubrication shell 1 and the second lubrication shell 2 to achieve the positioning and assembly of the fixed base 6 with oil supply structure such as oil reservoir 5 inside the corresponding first lubrication shell 1 and second lubrication shell 2. Then, the user can open the pipe valve 13 and inflate the locking airbag 18 installed on the mounting strip 16 through the air guide tube 12 with a syringe to make it expand and snap into the locking hole 17 inside the mounting slot 15. The locking airbag 18 and the locking hole 17 in the horizontal position can achieve the locking of the vertically set mounting slot 15 and mounting strip 16. This not only improves the firmness of the fixed base 6 with oil supply structure such as oil reservoir 5 when installed on the corresponding first lubrication shell 1 and second lubrication shell 2, but also makes it easy to release air for disassembly.

[0031] The first lubrication shell 1 and the second lubrication shell 2 are symmetrically distributed about the vertical center line of the slider body 3;

[0032] Both ends of the top of the slider body 3 are provided with external screw holes 4;

[0033] The rolling limiting cavity 20 is provided with an oil distribution hole that matches the lubrication ball 11 on the side near the slider body 3;

[0034] The outer wall of the lubricating ball 11 and the inner wall of the rolling limiting cavity 20 are both provided with an epoxy ceramic wear-resistant coating.

[0035] Spring 7 is mounted on telescopic block 10, and the oil cotton body 9 is made of high-density fiber.

[0036] The top of the oil storage box 5 is provided with an oil filling port 19, and a sealing plug is snapped onto the oil filling port 19.

[0037] In use, this embodiment of the application demonstrates that by symmetrically arranging the first lubricating shell 1 and the second lubricating shell 2 on both sides of the slider body 3, and by providing a rolling structure consisting of a rolling limiting cavity 20 matching the guide rail and lubricating balls 11 inside both the first lubricating shell 1 and the second lubricating shell 2, rolling friction is used instead of traditional sliding friction to reduce the impact of friction. An exposed oil reservoir 5 is provided above the first lubricating shell 1 and the second lubricating shell 2 to facilitate the replenishment of lubricating oil. During actual operation, the lubricating oil inside the oil reservoir 5 flows through the oil pipe 14 to the oil cotton body 9, thereby causing the slider body 3 to slide on the corresponding guide rail and drive the lubricating balls 11. During the movement of the contact guide rail outer wall, the lubricating balls 11 will sequentially pass through the oil cotton body 9 to carry the oil onto the outer wall of the guide rail. Compared with the ordinary method of directly adding liquid lubricating oil to the ball structure, this method provides the advantages of providing a stable oil supply, extending the maintenance interval, and avoiding oil waste. At the same time, by using the elastic telescopic structure composed of telescopic blocks 10 and springs 7 evenly connected between the fixed base 6 and the drive base 8, elastic pressure is applied to the drive base 8, causing the oil cotton body 9 fixed on the drive base 8 to press the lubricating balls 11 towards the guide rail. This pressure helps the oil inside the oil cotton body 9 to be distributed onto the lubricating balls 11, further optimizing the self-lubricating effect.
