Description

Technical Field

[0001] The utility model relates to the technical field of guide rail structures, in particular to a guide rail steel ball lubricating oil filling mechanism. Background Technique

[0002] A steel ball slide rail is a slide rail that uses high-precision steel balls as rolling elements. Generally, an outer strip of the slide rail is embedded with a bead sheet for fixing the steel balls on both sides. The moving part is placed on the bead sheet, and the moving part slides forward through the rolling of the steel balls. It is mostly used in cabinets, wardrobe drawers, toolboxes, tool cabinets, fire trucks, etc.

[0003] Due to the fine steel ball design of the steel ball guide rail, although the pulling and sliding are smooth, after a long time, dust and other debris adhere to the surface of the steel balls, resulting in the solidification of the lubricating oil on the surface of the steel balls. It is necessary to lubricate the steel balls regularly. When adding lubricating oil, it is not convenient. Direct addition will cause the lubricating oil to drip, affecting the addition efficiency of the lubricating oil. Therefore, a guide rail steel ball lubricating oil filling mechanism is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A through groove is opened on the side of the rail sleeve plate, and a ball assembly is installed inside the through groove. An active rail group is movably installed inside the rail sleeve plate. The active rail group includes an inserted rail. Guide grooves are opened on both sides of the inserted rail. An adding hole is opened on the side of the top of the inserted rail, and an oil pipe is arranged below the adding hole. A sponge pad is adhesively attached to the guide groove of the inserted rail.

[0007] Preferably, a plug pin is inserted into the adding hole of the inserted rail, and a silica gel connecting plate is connected to the right side of the plug pin. The right side of the silica gel connecting plate is fixedly connected to the surface of the inserted rail. By inserting the plug pin into the adding hole of the inserted rail, it is convenient to close the adding hole of the inserted rail.

[0008] Preferably, a spherical storage groove is opened in the adding hole of the inserted rail. The oil pipe is designed to be inclined. The top of the oil pipe is connected and communicated with the bottom right side of the spherical storage groove of the inserted rail. Through the spherical storage groove design of the inserted rail, it is convenient to temporarily store the lubricating oil.

[0009] Preferably, two fastening cover plates are symmetrically connected to both sides of the top of the rail sleeve plate, and the fastening cover plates are inserted into the surface of the inserted rail through the guide grooves. By inserting the fastening cover plates into the guide grooves on the surface of the inserted rail, the inserted rail can be limited.

[0010] Preferably, a groove is formed in the left side of the top end of the rail sleeve plate, and a spring plate is installed inside the groove. The spring plate is butt-jointed and fixed to the rail sleeve plate through a locking bolt. A groove adapted to the spring plate is formed at the bottom end of the inserted rail. The inserted rail is limited by the groove of the inserted rail and the spring plate to prevent the inserted rail from disengaging from the inside of the rail sleeve plate when being pulled out to the left.

[0011] Preferably, the ball component includes a rotating shaft, and steel balls are rotatably installed inside the rotating shaft. The steel balls are abutted against the concave surface on the inner wall of the sponge pad. Through the design of independent steel balls, the steel balls can be replaced after being damaged.

[0012] Preferably, the rotating shaft penetrates through the inside of the bracket through a through hole, and a fixing bolt is inserted into the end of the rotating shaft through a threaded hole. The bracket is fixed to the inner wall of the through groove of the rail sleeve plate through a bolt. By pulling the steel balls, the rotating shaft can be driven to disengage from the through hole of the bracket, ensuring the convenience of replacing the steel balls.

[0013] The utility model at least has the following beneficial effects:

[0014] 1. By setting the movable rail group, quick lubrication of the surface of the steel balls is realized. Compared with the traditional structure, in this device, an adding hole is formed at the top end of the inserted rail, an oil pipe is arranged below the adding hole, the sponge pad is attached to both sides of the inserted rail, the lubricating oil enters from the adding hole, is absorbed by the sponge pad after passing through the oil pipe, and the upper inner side of the sponge pad contacts the steel balls, so that the sponge pad lubricates the surface of the steel balls during the pulling movement of the inserted rail, ensuring the convenience of filling the lubricating oil.

[0015] 2. By setting the ball component, independent replacement of the steel balls is realized. This device changes the traditional installation method of the steel balls. By rotating and removing the fixing bolt from the threaded hole of the rotating shaft, the rotating shaft can be pulled out of the through hole of the bracket, facilitating the independent replacement of the steel balls after they are taken off, ensuring the convenience of replacing the steel balls.

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Referring to Figures 1-4 , a guide rail steel ball lubricating oil filling mechanism includes a guide rail assembly 1. The guide rail assembly 1 includes a rail sleeve plate 11. A through groove is opened on the side of the rail sleeve plate 11, and a ball assembly 3 is installed inside the through groove. An inner inserted rail 21 is movably installed inside the rail sleeve plate 11. Guide grooves are opened on both sides of the inner inserted rail 21. An adding hole is opened on the top side of the inner inserted rail 21, and an oil pipe 25 is arranged below the adding hole. A sponge pad 22 is adhesively attached to the guide groove of the inner inserted rail 21.

[0024] A plugging pin 23 is inserted into the adding hole of the inner inserted rail 21, and a silicone connecting plate 24 is connected to the right side of the plugging pin 23. The right side of the silicone connecting plate 24 is fixedly connected to the surface of the inner inserted rail 21.

[0025] A spherical storage groove is opened in the adding hole of the inner inserted rail 21. The oil pipe 25 is inclined. The top end of the oil pipe 25 is connected and communicated with the bottom right side of the spherical storage groove of the inner inserted rail 21.

[0026] Two buckle cover plates 12 are symmetrically connected to both sides of the top end of the rail sleeve plate 11, and the buckle cover plates 12 are inserted into the surface of the inner inserted rail 21 through the guide grooves.

[0027] A groove is opened on the left side of the top end of the rail sleeve plate 11, and a spring plate 13 is installed inside the groove. The spring plate 13 is butt-jointed and fixed to the rail sleeve plate 11 through a locking bolt 14. A groove adapted to the spring plate 13 is opened at the bottom end of the inner inserted rail 21.

[0028] The ball assembly 3 includes a rotating shaft 32 , and a steel ball 33 is rotatably mounted inside the rotating shaft 32 . The steel ball 33 abuts against the concave surface on the inner wall of the sponge pad 22 .

[0029] The rotating shaft 32 passes through the inside of the bracket 31 through the through hole, and a fixing bolt 34 is inserted into the end of the rotating shaft 32 through a threaded hole. The bracket 31 is fixed to the inner wall of the through groove of the rail sleeve plate 11 by the bolt.

[0030] After the lubricating oil is added to the adding hole of the inner rail 21, the plugging pin 23 can be inserted into the adding hole of the inner rail 21 to close the adding hole of the inner rail 21. The silicone connecting plate 24 can connect and fix the inner rail 21 to the side of the plugging pin 23 to prevent the plugging pin 23 from loosening and falling. The spherical storage groove design of the inner rail 21 can facilitate temporary storage of the lubricating oil, and facilitate the lubricating oil to penetrate the sponge pad 22 through the oil pipe 25. When the inner rail 21 drives the sponge pad 22 to move on the surface of the steel ball 33, the steel ball 33 can be lubricated conveniently. When the inner rail 21 moves in the rail sleeve 11, the buckle cover plate 12 is inserted in the guide groove on the surface of the inner rail 21 to limit the inner rail 21 to prevent the inner rail 21 from moving. When the inner rail 21 moves on the surface of the rail sleeve 11, the spring plate 13 can move in the groove at the bottom end of the inner rail 21, and the groove of the inner rail 21 and the spring plate 13 are used to limit the inner rail 21 from being separated from the inside of the rail sleeve 11 when it is pulled to the left. When the inner rail 21 has a sponge pad 22 to cooperate with the steel ball 33 to roll, the sponge pad 22 can lubricate the surface of the steel ball 33. Through the independent design of the steel ball 33, the steel ball 33 can be replaced after it is damaged. The fixing bolt 34 is rotated and moved in the threaded hole of the rotating shaft 32, and then the fixing bolt 34 is pulled out of the rotating shaft 32. At this time, the steel ball 33 can be pulled out, and then the rotating shaft 32 can be driven to separate from the through hole of the bracket 31, thereby ensuring the convenience of replacing the steel ball 33.

[0031] Working principle: According to the attached Figure 2 With attached Figure 3 As shown, during the process of adding lubricating oil, the plugging pin 23 can be moved to pull the plugging pin 23 out of the surface of the inner rail 21. At this time, the lubricating oil is put into the adding hole of the inner rail 21 through the needle tube, and the lubricating oil can be immersed in the sponge pad 22 through the oil pipe 25. The inner rail 21 is pulled in the rail sleeve 11, and the inner rail 21 can drive the sponge pad 22 to roll on the surface of the steel ball 33, thereby facilitating the lubrication of the surface of the steel ball 33.

[0032] Secondly, according to the attached Figure 4As shown, after the steel ball 33 is damaged, a tool can be used to turn the knob of the fixing bolt 34, so that the shaft end of the fixing bolt 34 is disengaged from the threaded hole of the rotating shaft 32. Subsequently, the steel ball 33 can be pulled, so that the steel ball 33 drives the rotating shaft 32 to disengage from the through hole of the bracket 31, which facilitates the independent replacement of the steel ball 33.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention.
