Description

Technical Field

[0001] This utility model relates to the field of linear motion slides, and in particular to a silent linear motion slide. Background Technology

[0002] A linear slide is a mechanical structure that provides linear motion. It mainly comes in two types: synchronous belt type and ball screw type. When the slider of a linear slide moves, friction and noise are generated between it and the slide rail. Over time, this can easily cause wear on the slide rail and slider, thus reducing the service life of the linear slide. Current technology typically reduces friction by adding lubricating oil to the outer wall of the slide rail. However, the lubricating oil flows downwards under gravity after being added to the outer wall of the slide rail, resulting in reduced lubricating oil utilization and requiring frequent re-lubrication by the operator, making it inconvenient to use. Utility Model Content

[0019] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model.

[0020] Example 1

[0021] As attached Figure 1-2 As shown, this application provides a silent linear motion slide, including a slide rail 1, a slider 2, a lubrication assembly 3, and an opening and closing assembly 4;

[0022] Sliding slider 2 is slidably connected to slide rail 1, and sliding slider 2 is a hollow structure;

[0023] Both the lubrication component 3 and the opening / closing component 4 are located inside the slider 2, and the opening / closing component 4 is used to control the lubrication component 3.

[0024] The lubrication assembly 3 includes an oil injection hole 31, an oil groove 32, a hose 33, a limiting block 34, and a rigid tube 35;

[0025] The oil injection hole 31 is opened on the top of the slider 2, and the oil groove 32 is fixedly connected to the inside of the slider 2. The oil injection hole 31 and the oil groove 32 are connected. The oil groove 32 is a closed structure and is used to store lubricating oil.

[0026] The hose 33 is fixedly connected to the bottom of the oil tank 32. The limiting block 34 is fixedly connected to the outer wall of the hose 33 and the limiting block 34 is fixedly connected to the inner wall of the slider 2. The rigid tube 35 is fixedly connected to the bottom end of the hose 33. The other end of the rigid tube 35 leads to the side of the slider 2 near the slide rail 1. The rigid tube 35 is used to deliver lubricating oil to the surface of the slide rail 1. An oil-absorbing sponge strip 5 is fixedly connected to the inner side of the slider 2. The oil-absorbing sponge strip 5 is located below the rigid tube 35.

[0027] In the above embodiments, lubricating oil is added into the oil groove 32 through the oil injection hole 31, and the lubricating oil flows to the outer wall of the slide rail 1 through the hose 33 and the rigid tube 35. As the slider 2 moves along the slide rail 1, the lubricating oil is driven by the slider 2 to gradually cover the surface of the slide rail 1, thereby reducing the friction between the slider 2 and the slide rail 1, thereby reducing noise and achieving a silent effect.

[0028] Example 2

[0029] The opening and closing assembly 4 includes a push plate 41, a first inclined slider 42, a second inclined slider 43, a spring 44, and a push rod 45;

[0030] The push plate 41 and the hose 33 are perpendicular to each other. The end of the push plate 41 near the hose 33 is rounded. The end of the push plate 41 away from the hose 33 is fixedly connected to the first inclined slider 42. The first inclined slider 42 is slidably connected to the second inclined slider 43. The side of the second inclined slider 43 is fixedly connected to the push rod 45. The bottom end of the push rod 45 extends through to the bottom of the slider 2, and the bottom end of the push rod 45 is rounded. The bottom end of the spring 44 is fixedly connected to the top of the push rod 45. The top of the spring 44 is fixedly connected to the bottom of the oil groove 32. The top of the slide rail 1 has multiple grooves. The bottom end of the push rod 45 is movably connected to the grooves.

[0031] In the above embodiment, when the slider 2 moves to the groove position, the spring 44 rebounds and drives the push rod 45 to move downward. The push rod 45 drives the second inclined slider 2 to move downward. The second inclined slider 43 drives the first inclined slider 42 to move laterally. The first inclined slider 42 drives the push plate 41 to move laterally, so that the push rod 45 is disengaged from the hose 33, thereby opening the hose 33. The rounded corner at the outer end of the push plate 41 prevents the push plate 41 from cutting the hose 33, thereby preventing damage to the hose 33 and causing lubricating oil leakage.

[0032] Working principle: The operator adds lubricating oil into the oil tank 32 through the oil injection hole 31. The lubricating oil flows into the hose 33. As the slider 2 moves along the slide rail 1, when the slider 2 moves to the groove position, the spring 44 rebounds and drives the push rod 45 to move downward. The push rod 45 drives the inclined slider 22 to move downward, and the inclined slider 23 drives the inclined slider 1 42 to move laterally. The inclined slider 1 42 drives the push plate 41 to move laterally, causing the push rod 45 to disengage from the hose 33, thereby opening the hose 33. The lubricating oil flows along the hose 3 into the rigid tube 35 and onto the surface of the slide rail 1. Subsequently, the lubricating oil is... The slider 2 gradually covers the surface of the slide rail 1, thereby reducing the friction between the slider 2 and the slide rail 1. After the slider 2 moves away from the groove, the rounded corner at the bottom of the push rod 45 presses against the groove, causing the push rod 45 to move upward. The push rod 45 resets the push plate 41 through the inclined slider 1 42 and the inclined slider 2 43. The push plate presses the hose 33 to seal the hose 33, preventing the lubricating oil from flowing downward. This ensures that only a fixed amount of lubricating oil is allowed to flow out within the distance between adjacent grooves, thereby reducing lubricating oil waste. The lubricating oil can be added during the movement of the slider 2, making it easy to use.

[0033] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
