Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically to a self-lubricating slide rail composite device. Background Technology

[0002] A slide rail is a linear guide device made of high-strength steel or aluminum alloy through precision stamping and extrusion. It is usually composed of dozens of parts such as a fixed rail, a movable rail, a ball bearing retainer, a damping buffer, an anti-disengagement buckle, and a preload adjustment screw. It converts sliding friction into rolling friction through a closed-loop ball bearing or polymer slider, enabling the smooth extension, retraction, hovering, and locking of drawers, server racks, industrial robotic arms, and even aircraft seats within a load range of a few kilograms to hundreds of kilograms. This allows furniture, home appliances, medical equipment, rail transportation, and even spacecraft doors to achieve a quiet, labor-saving, and long-lasting linear motion experience.

[0003] Lubrication is required for slide rails to establish a continuous low-shear oil film or solid transfer film between the two contact surfaces, which transforms the high frictional wear of the metal into low internal loss within the lubricant, thereby reducing starting force, suppressing creep, reducing noise, and removing wear debris and heat, ultimately extending the life of the slide rail and maintaining positioning accuracy.

[0004] When the slide rail is first used or restarted after a long period of shutdown, the solid self-lubricating transfer film has not yet been fully formed. The transient friction coefficient between the slide plate and the metal track surface increases sharply, and the interfacial shear stress rises sharply. Under the combined action of high load and micro-slippage, scratches, grooves, or even seizing and jamming occur, resulting in early failure. Therefore, a self-lubricating slide rail composite device is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figures 1-6 This utility model provides a technical solution:

[0028] A self-lubricating slide rail composite device includes a track 1, a slide plate assembly 2 slidably connected to the outer side of the track 1, and a drive control assembly 3 fixedly connected to the upper end of the slide plate assembly 2 by bolts. The slide plate assembly 2 includes a slide plate body 21, and the inner side of the slide plate body 21 is provided with a column groove 23, a cross 24, a filling hole 25, an oil storage tank 27 and an oil distribution hole 28. A silicone duckbill valve 26 is fixedly connected to the inner side of the filling hole 25, and a cross silicone valve 29 is fixedly connected to the inner side of the oil distribution hole 28. The drive control assembly 3 includes a fixing plate 31, a first rubber sealing ring 32 is fixedly connected to the outer side of the fixing plate 31, and an electric telescopic rod 33, a columnar plate 34 and a pressure rod 36 are fixedly connected to the bottom end of the fixing plate 31 in sequence. A second rubber sealing ring 35 is fixedly connected to the outer side of the columnar plate 34. The fixing plate 31 is fixedly connected to the upper end of the slide plate body 21 by bolts.

[0029] Furthermore, the device uses an electric telescopic rod 33 to instantly pressurize the slide rail before it starts, automatically establishing a continuous oil film, significantly reducing the starting torque, eliminating crawling and abnormal noise, and avoiding scratches, seizing, and jamming during the first slide after a long period of shutdown, thereby extending the slide rail's life, maintaining positioning accuracy, and saving on manual lubrication costs.

[0030] As a further implementation of this solution, the inner side of the skateboard body 21 is slidably connected to the outer side of the track 1, and a track groove is provided at the lower end of the skateboard body 21.

[0031] Furthermore, by setting up the above, the lubrication point is directly aligned with the friction pair, and the oil film can instantly cover the entire sliding surface, significantly reducing the starting torque and reducing dry friction damage.

[0032] As a further implementation of this solution, the column groove 23 is located at the rear end of the filling hole 25. The column groove 23 is connected to the filling hole 25 through the cross passage 24. The cross passage 24 is located at the upper end of the column plate 34 and at the lower end of the silicone duckbill valve 26.

[0033] It should be noted that: a channel is provided on the inner side of the skateboard body 21 near the filling hole 25, and the filling hole 25 is connected to the oil storage tank 27 through the channel. The front and rear ends of the oil storage tank 27 are fixedly connected to the glass plate 22 by sealant.

[0034] Furthermore, the above setup creates a compact, enclosed oil chamber, which reduces space requirements while ensuring stable oil pressure and achieves bidirectional equal distribution of lubricating oil, ensuring uniform lubrication of the left and right rail grooves.

[0035] As a further implementation of this scheme, the oil distribution hole 28 is close to the lower end of the oil storage tank 27, the oil distribution hole 28 is close to the upper end of the track groove of the slide body 21, and the oil distribution hole 28 is connected to the oil storage tank 27.

[0036] Furthermore, the above settings allow oil droplets to fall vertically and distribute oil precisely, thus improving lubrication efficiency.

[0037] As a further implementation of this solution, the fixed plate 31 is shaped as two cylinders with different diameters, and the cylindrical plate 34 has an annular groove near the second rubber sealing ring 35.

[0038] It should be noted that: the outer side of the first rubber sealing ring 32 is in contact with the inner side of the column groove 23, and the column plate 34 slides on the inner side of the column groove 23, with the outer side of the column plate 34 in contact with the inner side of the column groove 23;

[0039] Furthermore, the above-mentioned setup facilitates quick positioning and installation, enhances sealing and clamping force, and utilizes the expansion of the gas inside the slide plate body 21 to expel the lubricating oil.

[0040] Specifically: the outer walls of the first rubber sealing ring 32 and the cylindrical plate 34 are both in contact with and slide against the inner wall of the column groove 23, forming a double guiding seal, which suppresses oil side leakage and gas flow, maintains stable oil pressure, and extends the maintenance-free cycle of the entire lubrication module.

[0041] Workflow: To lubricate the track 1 and the skateboard assembly 2, first install the device by embedding the drive control assembly 3 entirely into the column groove 23, ensuring the fixing plate 31 faces upwards. Once the through hole on the inner side of the fixing plate 31 aligns with the screw hole on the upper end of the skateboard body 21, secure the fixing plate 31 to the skateboard body 21 with bolts. Then, insert the syringe plug through the silicone duckbill valve 26 until it deforms, injecting lubricating oil into the filling hole 25. At this point, the lubricating oil will flow through the skateboard body... The channels inside body 21 allow lubricant to flow into the left and right oil reservoirs 27 respectively, until the lubricant reaches the lower part of the crossbar 24. At this point, lubrication can be applied between the skateboard body 21 and the track 1. The electric telescopic rod 33 is powered by a battery and controlled via Bluetooth. Before the skateboard body 21 slides to the outside of the track 1, the bottom of the silicone duckbill valve 26 is in close contact with the upper end of the track 1. Through the friction between the pressure rod 36 and the track 1, the skateboard body 21 is positioned against the fixed plate 31. When the electric telescopic rod 33 is activated, it retracts, causing the cylindrical plate to move. As the pressure rod 34 and pressure bar 36 move upward, the second rubber sealing ring 35 seals the space between the cylindrical plate 34 and the slide body 21. At this time, the air pressure inside the column groove 23 expands, and the silicone duckbill valve 26 allows for one-way gas flow. Due to the air pressure expansion, multiple cross-shaped silicone valves 29 open under pressure, and the lubricating oil inside the oil reservoir 27 flows through the oil distribution hole 28 to the space between the track 1 and the slide body 21, thus achieving lubrication. At this time, lubricating oil is generated inside the slide groove of the slide body 21, thereby reducing the friction when the slide body 21 slides. After stopping, the electric telescopic rod 33 pushes the cylindrical plate 34 and the pressure rod 36 downward. External air enters the filling hole 25 through the silicone duckbill valve 26, facilitating the re-lubrication of the slide body 21 and the track 1. Based on the above principles, the device achieves the effect of lubrication before the slide rail moves, preventing the instantaneous increase in the transient friction coefficient between the slide and the track 1 surface when restarting after a long period of shutdown, before the solid self-lubricating transfer film has been fully formed. This improves the smoothness of the slide rail movement and significantly reduces the phenomenon of slide rail slippage failure caused by scratches, grooves and jamming.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
