[0002] A slide rail assembly refers to a complete, ready-to-use sliding mechanism system that enables objects to move horizontally in a stable manner.

[0003] However, in current slide rail assemblies, the internal balls wear down due to long-term rolling, which increases the gap between the slider and the rail, affecting the sliding accuracy. Furthermore, dust adhering to the rail surface during slider movement also increases the wear of the balls. Therefore, a high-precision slide rail assembly is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision slide rail assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-precision slide rail assembly, including two rails, with V-shaped grooves opened on the left and right end surfaces of the two rails, and sliders provided above the two rails, the two sliders being located on the same horizontal line, and a fixing plate connecting the two sliders, and a recess being provided transversely through the interior of the two sliders.

[0006] A dust removal mechanism is provided on the outer side of each of the two recesses, and a dust collection mechanism is installed and removed inside each of the two recesses. A ball bearing mounting bracket is connected to the outer surface of each of the two sliders, and a compensation mechanism is provided below the ball bearing mounting bracket.

[0007] Both tracks have a base plate detachably connected to their lower surfaces.

[0008] Preferably, the upper surface of the fixing plate is provided with a hollow structure running from top to bottom.

[0024] Example 1

[0025] like Figures 1 to 4 As shown in this embodiment, a high-precision slide rail assembly includes a rail 1, and two rails 1 are provided. V-grooves 2 are provided on the left and right end surfaces of the two rails 1. A slider 3 is provided above the two rails 1. By providing the V-grooves 2, the slider 3 is constrained in both the lateral and radial directions, ensuring the stability of the overall structure and improving the sliding accuracy. The two sliders 3 are located on the same horizontal line, and a fixing plate 4 is connected between the two sliders 3. A notch 5 is provided transversely through the interior of the two sliders 3. By providing the notch 5, the overall weight of the slider 3 is reduced, and it is also convenient to install other parts and components necessary for operation inside the slider 3.

[0026] Dust removal mechanisms 6 are provided on the outer sides of both recesses 5. The dust removal mechanisms 6 can remove dust on the path of the slider 3 when it slides, so as to avoid dust wear on the balls and cause errors in sliding accuracy. Dust collection mechanisms 7 are installed inside both recesses 5. The dust collection mechanisms 7 can collect the cleaned dust. The outer surfaces of both sliders 3 are connected to ball mounting brackets 8. A compensation mechanism 10 is provided below the ball mounting brackets 8. Multiple balls are pre-installed inside the ball mounting brackets 8 and it is located at the bottom middle of the slider 3. There are reserved spaces at both ends of the slider 3 for the dust removal mechanism 6 to work. The compensation mechanism 10 can compensate for the gaps when the balls are worn after long-term operation, so as to avoid affecting the sliding accuracy.

[0027] Both tracks 1 have a base plate 11 detachably connected to their lower surfaces, which facilitates the disassembly and replacement of components such as the tracks 1.

[0028] Furthermore, the upper surface of the fixing plate 4 is provided with a hollow structure running from top to bottom, which can reduce the overall weight.

[0029] Furthermore, the dust removal mechanism 6 includes a conveying channel 601, an inner cavity 602, and an entry channel 603. The conveying channel 601 is provided on both the left and right sides of the recess 5. The bottom ends of the two conveying channels 601 are connected to the inner cavity 602, and the inner cavity 602 is opened inside the slider 3. The outer surface of the two inner cavities 602 is provided with the entry channel 603. When the slider 3 slides, the entry channel 603 faces the track 1 at both ends of the slider 3 to avoid air extraction, so that the surface dust enters the interior of the inner cavity 602 and is finally conveyed to the dust collection mechanism 7 through the conveying channel 601.

[0030] Furthermore, the dust collection mechanism 7 includes a dust collection box 701, an inlet 702, and an outlet 703. The dust collection box 701 is connected inside the recess 5. The inlets 702 are reserved on both the left and right ends of the dust collection box 701, and the outlet 703 is opened on the upper surface of the dust collection box 701. Dust enters the dust collection box 701 and is stored. When the device is not in use, the dust collection box 701 can be disassembled and the collected dust can be poured out through the outlet 703. The connection method of the dust collection box 701 inside the recess 5 can be selected according to the actual situation, as long as it can be disassembled.

[0031] Furthermore, a miniature air pump is pre-installed inside the dust collection box 701. The position of the inlet 702 corresponds to the top of the conveying channel 601. When the dust collection box 701 is installed and fixed, the inlet 702 will be aligned with the top of the conveying channel 601 to ensure that dust can enter the dust collection box 701. The miniature air pump is installed in a suitable position inside the dust collection box 701. The model is selected from existing products on the market according to actual needs, and conventional installation and power supply methods are adopted.

[0032] Furthermore, the outer surface of the ball mounting bracket 8 is provided with fixing bolts 9, and the other end of the fixing bolts 9 passes through the interior of the slider 3. The shape of the ball mounting bracket 8 matches the bottom shape of the slider 3, which facilitates the assembly and disassembly of the ball mounting bracket 8. The surface of the ball mounting bracket 8 near the track 1, that is, the two inclined surfaces of the V-groove 2, are provided with balls.

[0033] Furthermore, the compensation mechanism 10 includes a groove 1001, a connecting plate 1002, and a through hole 1003. The groove 1001 is located at the bottom of the track 1, and the connecting plate 1002 is connected inside the groove 1001. The through hole 1003 is located below the connecting plate 1002 and is located inside the track 1. An electric telescopic rod is installed inside the through hole 1003, and the top of the electric telescopic rod is fixedly connected to the connecting plate 1002. When the ball bearings are worn due to long-term sliding, the user can judge whether there is shaking or noise when using the device. At this time, the connecting plate 1002 can be pushed up by the electric telescopic rod installed inside the through hole 1003, which in turn pushes the slider 3, so that the ball bearings on the ball bearing mounting bracket 8 are stably in contact with the inclined surface of the V-groove 2. It should be noted that multiple electric telescopic rods are synchronously extended and retracted by a single controller, and the controller and power supply are installed in appropriate positions on the track 1.

[0034] The usage method of this embodiment is as follows: When the slider 3 slides, the entry channel 603 is located at both ends of the slider 3 facing the track 1 to avoid air extraction, so that the surface dust enters the interior of the inner cavity 602 and is finally transported to the dust collection mechanism 7 through the conveying channel 601. When the dust collection mechanism 7 has collected enough dust, it can be removed and the dust can be emptied. When the ball bearings are worn due to long-term sliding, the connecting plate 1002 can be pushed up by the electric telescopic rod inside the mounting hole 1003, which in turn pushes the slider 3 up, so that the ball bearings on the ball bearing mounting bracket 8 are in stable contact with the inclined surface of the V-groove 2.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
