Description

Technical Field

[0001] This utility model relates to the field of cabinet guide rail technology, and in particular to a cabinet guide rail fine-tuning structure. Background Technology

[0002] Rack rails play a crucial role in server installation and management. Made of robust metal, the rails can withstand the weight of the server, ensuring the equipment is stable within the rack and preventing shaking or tipping. The rail design allows servers to slide easily into the rack, simplifying the installation process and eliminating the need for complex tray installations. It also supports servers sliding out of the rack, facilitating administrator access to the rear interfaces and internal components of the equipment for maintenance, upgrades, or troubleshooting.

[0003] However, traditional rack rails have a significant limitation in installation and positioning: their positions are usually fixed, offering only coarse adjustments in standard height units, and not fine-tuning. This means that when installing equipment, if high precision is required (e.g., strict alignment of panel gaps, optimized airflow, or precise cable connections), even a slight deviation in the initial installation position necessitates complete disassembly of the equipment, loosening of the rail fasteners, repositioning, and re-tightening. This process is time-consuming and labor-intensive, especially in racks with limited space or dense equipment. Therefore, we propose a rack rail fine-tuning structure. Utility Model Content

[0004] The main purpose of this utility model is to provide a cabinet guide rail fine-tuning structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cabinet rail fine-tuning structure includes a bracket body, an adjustment groove on the surface of the bracket body, a rail body inside the adjustment groove, several through holes on both opposite surfaces of the adjustment groove, several adjustment nuts I on the upper surface of the adjustment groove, an upper fine-tuning screw inside the adjustment nut I, and several adjustment nuts II on the bottom surface of the adjustment groove, a lower fine-tuning screw inside the adjustment nut II.

[0007] Preferably, the support body has two sets of fixing holes symmetrically formed on its surface.

[0008] By adopting the above technical solution, the fixing holes are standard installation interfaces, which are compatible with most cabinet products manufactured by the company on the market.

[0009] Preferably, the adjusting groove communicates with the through holes, and six through holes are provided.

[0010] Preferably, the position of the first adjusting nut is adapted to the position of the through hole opened on the upper surface of the adjusting groove, the first adjusting nut is threadedly engaged with the upper fine-tuning screw, and both the first adjusting nut and the upper fine-tuning screw are provided in three sets.

[0011] Preferably, the position of the second adjusting nut is adapted to the position of the through hole opened on the bottom surface of the adjusting groove, the second adjusting nut is threadedly engaged with the lower fine-tuning screw, and both the second adjusting nut and the lower fine-tuning screw are provided in three sets.

[0012] Preferably, the bottom end of the upper fine-tuning screw passes through the through hole opened on the upper surface of the adjustment groove and is tightly fitted with the upper surface of the guide rail body, and the top end of the lower fine-tuning screw passes through the through hole opened on the bottom surface of the adjustment groove and is tightly fitted with the bottom surface of the guide rail body.

[0013] By adopting the above technical solution, which uses six sets of symmetrically distributed through holes and three sets of upper adjusting nuts and upper fine-tuning screws, and three sets of lower adjusting nuts and lower fine-tuning screws, the fine-tuning module can be seamlessly adapted to the guide rail interfaces of various existing cabinet products while ensuring the uniformity of multi-point force and structural stability.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By adjusting the tight fit between the upper and lower fine-tuning screws in the groove and the guide rail body, operators can make millimeter-level precise adjustments to the vertical height and horizontal plane of the equipment carried by the guide rail body simply by turning the upper or lower fine-tuning screws without disassembling the server or loosening the guide rail body fixing parts. This completely solves the problem that traditional guide rails can only be positioned according to integer U and cannot finely correct position deviations, significantly improving installation efficiency and positioning accuracy.

[0016] 2. The design employs six symmetrically distributed through holes and three sets of upper adjusting nuts and upper fine-tuning screws, as well as three sets of lower adjusting nuts and lower fine-tuning screws. This design ensures uniform force distribution at multiple points and structural stability. Furthermore, the standardized layout of the adjusting grooves and through holes allows the fine-tuning module to seamlessly adapt to the guide rail interfaces of various existing cabinet products without altering the main cabinet structure. This significantly reduces manufacturing and modification costs and demonstrates high engineering practical value. Attached Figure Description

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A cabinet guide rail fine-tuning structure includes a bracket body 1. An adjustment groove 11 is formed on the surface of the bracket body 1. A guide rail body 2 is arranged in the adjustment groove 11. Several through holes 12 are formed on both opposite surfaces of the adjustment groove 11. Several adjusting nuts 13 are arranged on the upper surface of the adjustment groove 11. An upper fine-tuning screw 14 is arranged in the adjusting nut 13. Several adjusting nuts 15 are arranged on the bottom surface of the adjustment groove 11. A lower fine-tuning screw 16 is arranged in the adjusting nut 15.

[0028] In this embodiment, two sets of fixing holes 10 are symmetrically opened on the surface of the bracket body 1. The adjusting groove 11 communicates with the through hole 12. There are six through holes 12. The position of the adjusting nut 13 is adapted to the position of the through hole 12 opened on the upper surface of the adjusting groove 11. The adjusting nut 13 is threadedly engaged with the upper fine-tuning screw 14. There are three sets of adjusting nuts 13 and upper fine-tuning screw 14. The position of the adjusting nut 15 is adapted to the position of the through hole 12 opened on the bottom surface of the adjusting groove 11. The adjusting nut 15 is threadedly engaged with the lower fine-tuning screw 16. There are three sets of adjusting nuts 15 and lower fine-tuning screw 16. The bottom end of the upper fine-tuning screw 14 passes through the through hole 12 opened on the upper surface of the adjusting groove 11 and is tightly fitted with the upper surface of the guide rail body 2. The top end of the lower fine-tuning screw 16 passes through the through hole 12 opened on the bottom surface of the adjusting groove 11 and is tightly fitted with the bottom surface of the guide rail body 2.

[0029] Through the above scheme: tightening the upper fine-tuning screw 14 can press down the guide rail body 2, and tightening the lower fine-tuning screw 16 can push the guide rail body 2 up; when horizontal leveling is required, by tightening the upper and lower screw groups on both sides in a differentiated manner, the guide rail body 2 can be tilted in a controllable manner to achieve horizontal position correction. After adjustment, the guide rail body 2 is locked in the adjustment groove 11 at multiple points by the screw group to ensure stability.

[0030] It should be noted that when the guide rail height needs to be adjusted, tighten the upper fine-tuning screw 14. The upper fine-tuning screw 14 is screwed downward through the thread engagement with the adjusting nut 13. Its bottom end abuts against the upper surface of the guide rail body 2 and applies vertical downward pressure, forcing the guide rail body 2 to move downward along the adjusting groove 11. At the same time, loosen the lower fine-tuning screw 16. The lower fine-tuning screw 16 is pulled out downward through the thread engagement with the adjusting nut 15, releasing its support constraint on the bottom surface of the guide rail body 2, thereby achieving precise adjustment of the guide rail height. Conversely, if the guide rail height needs to be increased, loosen the upper fine-adjustment screw 14 to release the upper pressure, and simultaneously tighten the lower fine-adjustment screw 16 so that its top end abuts against the bottom surface of the guide rail body 2 and applies a vertical upward lifting force, driving the guide rail body 2 to move upward; when leveling is required, the screw groups on both sides of the guide rail body 2 are controlled independently: for example, when the left side needs to be raised, tighten the lower fine-adjustment screw 16 on that side to push up the left side of the guide rail, and simultaneously loosen the upper fine-adjustment screw 14 on the same side; when the right side needs to be lowered, tighten the upper fine-adjustment screw 14 on that side to press down the right side of the guide rail, and simultaneously loosen the lower fine-adjustment screw 16 on the same side. The differential displacement of the screw groups on both sides causes the guide rail body 2 to generate a controllable tilt angle in the adjustment groove 11, thereby driving the equipment fixed on it to rotate slightly in the horizontal plane until it reaches a precise horizontal position. After the height and level adjustment are completed, all the upper fine adjustment screws 14 and lower fine adjustment screws 16 are tightened simultaneously, so that the upper and lower surfaces of the guide rail body 2 form rigid multi-point contact with the screw groups respectively. Through the thread self-locking effect, the guide rail body 2 is firmly constrained in the adjustment groove 11, completely eliminating the risk of displacement.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
