Description

Technical Field

[0001] The utility model relates to the field of slide rails, in particular to an oil injection structure of a slide rail. Background Art

[0002] Linear guides, also known as linear rails, slides, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion situations. They can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] The prior art, such as announcement number: CN217081120U, discloses a linear slide rail that is easy to add lubricating oil to. In order to solve the problem that the slide rail will oxidize and rust after being used for a long time, and the existing slide rail needs to be manually smeared with lubricating oil, the excessive lubricating oil will fall and be wasted, through the cooperation between the long strip, compression spring, trapezoidal plate, L-shaped groove and other structures, the lubricating oil can move through the gap to the side of the inner wall of the L-shaped groove, so that the lubricating oil contacts the side of the sliding ball through the side of the inner wall of the L-shaped groove transverse groove, making the lubrication of the linear slide rail more convenient; through the cooperation between the T-shaped rod, tension spring, slot, round rod and other structures, by relaxing the tension spring, the T-shaped rod is moved to the side of the inner wall of the slot through the elastic potential energy of the tension spring, so that the triangle plate is fixed, so that the triangle plate can drive the lubricating oil on the lower side of the side of the slide rail body to scrape, so that the lubricating oil can be evenly applied to the side of the slide rail body, thereby reducing the waste of lubricating oil.

[0004] In short, the above-mentioned prior art is that an infusion channel connected to the inner ball is provided on the top of the slide seat on the slide rail, and triangular plates are provided on both sides of the inner wall of the slider seat to scrape the overflowed lubricating oil onto the surface of the slide rail. However, the amount of lubricating oil that can be stored in the infusion channel and the surface of the ball is relatively small. When the slide seat moves, the lubricating oil adhered to the surface of the ball will gradually transfer to the contacting surface of the slide rail. After the slide seat moves a short distance, the lubricating oil will be consumed. In addition, although the triangular plate can smear the overflowed lubricating oil on the surface of the slide rail, due to the height of the overflow position of the lubricating oil and the influence of the gravity on the sliding of the lubricating oil, the lubricating oil smeared near the upper side of the slide rail surface is relatively insufficient. For this reason, we propose an oil filling structure for the slide rail. Utility Model Content

[0006] To achieve the above-mentioned purpose, an oil injection structure for a slide rail comprises a slide rail body, the upper surface of the slide rail body is slidably connected to a sliding seat, the inner wall of the sliding seat is rotatably connected to a ball, a movable mechanism is arranged inside the sliding seat near the upper side, and the lower end of the movable mechanism is fixedly connected to the oil injection mechanism.

[0007] Furthermore: the movable mechanism includes a bidirectional roller, the bidirectional roller is rotatably connected to the inside of the sliding seat, a cam is fixedly connected to the middle of the bidirectional roller, and one end of the cam extends to the outside of the sliding seat.

[0008] Furthermore: both ends of the bidirectional roller are threadedly connected to supports, the two supports are respectively located on both sides of the slide rail body and the bottoms are fixedly connected to movable plates.

[0009] Furthermore: the upper surface of the movable plate is fixedly connected with a movable tube, one end of the movable tube extends to the inside of the fixed tube, the fixed tube is fixedly connected to the inside of the sliding seat and one end is connected to the oil tank.

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

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The figure shows a preferred embodiment of the utility model, an oil injection structure of a slide rail, including a slide rail body 1, a slide seat 2 is slidably connected to the upper surface of the slide rail body 1, a ball 3 is rotatably connected to the inner wall of the slide seat 2, a movable mechanism 4 is arranged near the upper side inside the slide seat 2, and an oil injection mechanism 5 is fixedly connected to the lower end of the movable mechanism 4.

[0021] Specifically, the movable mechanism 4 includes a bidirectional roller 6, which is rotatably connected to the inside of the sliding seat 2. A cam 7 is fixedly connected to the middle of the bidirectional roller 6, and one end of the cam 7 extends to the outside of the sliding seat 2, so that the cam 7 can be used to push the bidirectional roller 6 to rotate.

[0022] Specifically, both ends of the bidirectional roller 6 are threadedly connected with supports 8, the two supports 8 are respectively located on both sides of the slide rail body 1 and the bottoms are fixedly connected with movable plates 9; when the bidirectional roller 6 rotates, due to the reverse threads on both sides, the two sets of movable plates 9 can be simultaneously approached or moved away from the cam 7 through the supports 8.

[0023] Specifically, the upper surface of the movable plate 9 is fixedly connected with a movable tube 10, one end of the movable tube 10 extends to the inside of the fixed tube 11, the fixed tube 11 is fixedly connected to the inside of the sliding seat 2 and one end is connected to the oil tank 12; because one end of the movable tube 10 has a sufficient length, when the movable tube 10 moves with the movable plate 9, one end can always be located in the fixed tube 11 to obtain lubricating oil from the oil tank 12.

[0024] Among them, the outer wall of the sliding seat 2 is provided with an oil tank 12, and the height of the bottom oil outlet of the oil tank 12 is not lower than the height of the fixed pipe 11, which is convenient for the discharge of lubricating oil. It should be supplemented that the top of the oil tank 12 is provided with an oil filling hole.

[0025] Specifically, the oil filling mechanism 5 includes an oil drain pipe 13, which is fixedly connected to the lower surface of the movable plate 9. The lower surface of the movable plate 9 is fixedly connected with a U-shaped cotton 14 on the outer side of the oil drain pipe 13. The material of the U-shaped cotton 14 is sponge. It should be added that the surface of the oil drain pipe 13 is evenly provided with small-aperture oil holes. After the lubricating oil is slowly discharged from the oil holes, it is absorbed by one end of the U-shaped cotton 14. When the two groups of movable plates 9 are close to each other, so that one end of the U-shaped cotton 14 is in contact with the outer wall of the slide rail body 1, the lubricating oil absorbed by the U-shaped cotton 14 is smeared on the surface of the slide rail body 1, and with the movement of the sliding seat 2, the entire slide rail body 1 is fully smeared. It should be noted that the shape of the end of the U-shaped cotton 14 close to the inner wall of the slide rail body 1 is consistent with the shape of the inner wall of the slide rail body 1, so as to avoid insufficient application of the lubricating oil.

[0026] Among them, a partition is provided inside the sliding seat 2 between the two ends of the U-shaped cotton 14 close to the slide rail body 1 to limit the diffusion surface of the lubricating oil so that the surface of the slide rail body 1 has sufficient lubricating oil for smearing. The length of the end of the U-shaped cotton 14 close to the ball 3 is 3 mm shorter than the end of the U-shaped cotton 14 close to the ball 3, so that only the lubricating oil protruding excessively from the surface of the slide rail body 1 is absorbed at this place, avoiding the outflow of the lubricating oil and reducing the pollution to the surface of the slide rail body 1.

[0027] In this embodiment, the cam 7 can push the bidirectional roller 6 to rotate. When the bidirectional roller 6 rotates, since the two sides are provided with opposite threads, the support 8 can make the two sets of movable plates 9 approach or move away from the cam 7 at the same time, so as to control whether the U-shaped cotton 14 contacts the inner wall of the slide rail body 1;

[0028] When the oil tank 12 is filled with sufficient lubricating oil, the lubricating oil flows into the oil drain pipe 13 along the fixed tube 11, the movable tube 10 and the movable plate 9. After the lubricating oil is slowly discharged from the oil hole of the oil drain pipe 13, it is absorbed by one end of the U-shaped cotton 14. When the two groups of movable plates 9 are close to each other, so that one end of the U-shaped cotton 14 is in contact with the outer wall of the slide rail body 1, the lubricating oil absorbed by the U-shaped cotton 14 is smeared on the surface of the slide rail body 1, and with the movement of the sliding seat 2, the entire slide rail body 1 is fully smeared.

[0029] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
