Description

Technical Field

[0001] This utility model relates to the field of cabinet equipment installation technology, and in particular to a chassis slide rail installation structure and chassis. Background Technology

[0002] In the field of electrical equipment, the chassis, as a key component that carries electronic components, is usually installed inside a cabinet using a sliding rail structure. The common installation method is as follows: a pair of sliding rails are fixed to both sides of the cabinet, and the inner rails of the two sliding rails are removed and installed on both sides of the chassis. During installation, the operator needs to lift the chassis, precisely align the inner rails on both sides of the chassis with and insert them into the outer rail slots fixed to the cabinet, and finally push the chassis horizontally into the cabinet to complete the installation.

[0003] However, in practical applications, the above-mentioned slide rail mounting structure has the following problems: First, installation and alignment are difficult, operation is inconvenient, and components are easily damaged. When the chassis is large and heavy, operators need to expend a lot of physical strength to lift the chassis while ensuring that the inner rails on both sides of the chassis are horizontally aligned with the outer rail tracks on the rack. The alignment process is difficult and inefficient, and misalignment can easily cause the slide rails to jam or collide, thus damaging the slide rail structure. It is not suitable for scenarios requiring frequent loading and unloading. Second, the slide rail specifications have poor universality and low interchangeability. Different sizes and weights of chassis require different slide rail specifications, resulting in differences in the mounting hole positions of different specifications of slide rails. When it is necessary to replace the slide rail, it is often impossible to match the original mounting hole positions, requiring re-drilling or replacement of the entire chassis shell, which damages the appearance of the chassis and increases additional costs. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a slide rail mounting structure, which aims to solve the technical problems of existing slide rail mounting structures, such as difficulty in installation and alignment, inconvenience in operation and easy damage to components; as well as poor universality and low interchangeability of slide rail specifications.

[0005] One aspect of this utility model is to provide a chassis slide rail mounting structure for detachably connecting the chassis and the inner rail of the slide rail, comprising: The mounting component is used to fix it to the inner rail of the slide rail, and the mounting component is provided with at least one mounting part; At least one limiting member is used to be fixedly disposed on the side of the chassis. The limiting member is provided with a limiting part, wherein the chassis and the inner rail of the slide rail are detachably connected by the locking engagement of the limiting part with the mounting part.

[0006] In addition, the chassis slide rail mounting structure described above according to this utility model may also have the following additional technical features: Furthermore, the mounting component is a mounting plate, and the mounting part is a slot formed on the top of the mounting plate. A plurality of slots are spaced apart along the length direction of the mounting plate, and the depth direction of the slot is set along the width direction of the mounting plate. The mounting plate has multiple mounting holes, and the mounting plate and the slide rail are fixedly connected by fasteners passing through the mounting holes and threadedly connected to the inner rail of the slide rail.

[0007] Furthermore, guide rounded corners are provided on both sides of the entrance of the card slot.

[0008] Furthermore, the slot has a U-shaped structure.

[0009] Furthermore, the limiting component includes a limiting rod and a connecting bolt. The limiting rod includes a first end, a limiting part, and a second end connected in sequence. The limiting part is a locking rod structure and is adapted to a locking groove. The second end is provided with an internal threaded hole for engaging with the connecting bolt to fix the limiting rod to the side of the chassis.

[0010] Furthermore, the diameter of the limiting portion is smaller than the diameter of the second end, and the diameter of the second end is smaller than the diameter of the first end.

[0011] Furthermore, the limiting member also includes a gasket, and the connecting bolt passes through the gasket, the side of the chassis, and is threadedly connected to the second end to fix the limiting member on the side of the chassis.

[0012] Another aspect of this utility model is to provide a chassis, including a chassis body and the aforementioned chassis slide rail mounting structure, wherein at least one side of the chassis body is fixedly provided with the at least one limiting member.

[0013] Compared to existing technologies, the advantages of this utility model's chassis slide rail mounting structure are as follows: It facilitates installation and disassembly, significantly reducing the difficulty of alignment. Specifically, when using this invention, simply align the limiting part with the mounting part, and the chassis itself will automatically engage, greatly reducing the physical exertion of operators and preventing slide rail jamming or impact damage due to alignment deviations. This is particularly suitable for scenarios with large chassis, heavy weight, and frequent loading and unloading. Disassembly only requires lifting the chassis, further improving operational efficiency. Simultaneously, it significantly improves the universality and interchangeability of slide rail specifications, reducing usage costs. Specifically, the elongated mounting plate has multiple spaced mounting holes, which can accommodate the mounting holes on the inner rails of different slide rail specifications, eliminating the need for re-drilling or replacing the chassis shell due to changes in slide rail specifications.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Please see Figures 1 to 6 The diagram shows the chassis slide rail mounting structure of this utility model, which is used to detachably connect the chassis 40 and the inner rail of the slide rail 50. The chassis slide rail mounting structure includes a mounting member 10 for fixed connection with the inner rail of the slide rail 50, and at least one limiting member 20 for fixedly set on the side of the chassis 40. The mounting member 10 is provided with at least one mounting part 11, and the limiting member 20 is provided with a limiting part 212. In actual use, the detachable connection between the chassis 40 and the inner rail of the slide rail 50 is realized through the snap-fit ​​cooperation between the limiting part 212 and the mounting part 11.

[0021] In this embodiment, the mounting component 10 is a long, narrow mounting plate. The length of the mounting plate can be adapted to the length of the inner rail of the slide rail 50. The mounting part 11 is a slot located on the top of the mounting plate. Multiple slots are spaced apart along the length of the mounting plate, and the spacing can be adapted to the weight and size of the chassis 40 to ensure balanced load-bearing after connection. The depth of the slot opening is set along the width of the mounting plate. The mounting plate has multiple mounting holes 12. Fasteners 30 pass through the mounting holes 12 and are threadedly connected to the inner rail of the slide rail 50 to achieve a fixed connection between the mounting plate and the slide rail 50. The fasteners can be bolts, screws, or other connection structures to prevent the mounting plate from loosening during use.

[0022] Furthermore, guide rounded corners are provided on both sides of the entrance of the slot. The guide rounded corners can guide the limiting part 212 when it is engaged in the slot, thereby improving the ease of assembly. In some embodiments, guide slopes can be provided on both sides of the entrance of the slot.

[0023] Furthermore, the slot has a U-shaped structure.

[0024] In this embodiment, the limiting component 20 includes a limiting rod 21 and a connecting bolt 22. The limiting rod 21 includes a first end 211, a limiting part 212, and a second end 213 connected in sequence. The limiting part 212 is a locking rod structure, the shape and size of which are adapted to the locking groove to ensure that the limiting part 212 can be accurately locked into the locking groove and achieve a stable fit. The second end 213 is provided with an internal threaded hole for cooperating with the connecting bolt 22 to fix the limiting rod 21 to the side of the chassis 40 and prevent the limiting rod 21 from falling off. In this embodiment, the end face of the first end 211 is provided with a slot and a chamfer structure. The slot can be adapted to common tools such as a flathead screwdriver. By inserting a flathead screwdriver into the slot and rotating the limiting rod 21, the installation angle or tightness of the limiting rod 21 on the side of the chassis 40 can be finely adjusted, thereby adjusting the position of the limiting rod 21.

[0025] Furthermore, the diameter of the limiting part 212 is smaller than the diameter of the second end 213, and the diameter of the second end 213 is smaller than the diameter of the first end 211. This gradient design makes it easier for operators to quickly identify the position of the limiting part 212, enabling the limiting part 212 to be quickly aligned with the slot and accurately engaged during assembly.

[0026] Furthermore, the limiting member 20 also includes a washer. A connecting bolt 22 passes through the washer, and the side of the housing 40 is threadedly connected to the second end 213 to fix the limiting member 20 on the side of the housing 40. The washer enhances the anti-slip properties of the threaded connection and prevents the connecting bolt 22 from loosening due to vibration. In this embodiment, the side of the housing 40 is provided with a connecting hole for the connecting bolt 22 to pass through. The washer includes a first washer 23 and a second washer 24. The first washer 23 is a notched elastic washer. The notch design facilitates quick insertion of the washer into the connecting bolt 22. The elastic material can produce elastic deformation when the bolt is tightened, further improving the anti-slip effect. The second washer 24 is a flat washer. The flat washer can be used in conjunction with the elastic washer to further increase the contact area and improve the fixing stability.

[0027] Another aspect of this utility model is to provide a chassis, including a chassis body and the aforementioned chassis slide rail mounting structure, wherein at least one limiting member 20 is fixedly provided on at least one side of the chassis body. In this embodiment, multiple limiting members are respectively provided on both sides of the chassis body. When it is necessary to install the chassis on the slide rail, the installation can be completed by the cooperation of the limiting members and the mounting members, effectively improving the installation flexibility and applicability of the chassis.

[0028] In practical application, the working principle of the chassis slide rail mounting structure of this application is as follows: First, the mounting part 10, i.e., the long strip mounting plate, is threadedly connected to the inner rail of the slide rail 50 through the mounting holes 12 on the mounting plate 10 using fasteners such as bolts or screws, so that the plate body of the mounting plate is in close contact with the surface of the inner rail, thereby completing the fixation of the mounting part 10 and the inner rail of the slide rail 50. Then, limiting parts are installed on the connecting holes on both sides of the chassis 40. Specifically, the limiting rod of the limiting part is fixed to the side of the chassis body by connecting bolts, a first washer, and a second washer, ensuring that the limiting rod is firmly installed. Finally, the limiting part of the limiting rod on the side of the chassis is aligned with the slot on the mounting part. Under the action of the chassis' own weight, the limiting part will engage with the slot, thereby completing the connection between the chassis and the inner rail of the slide rail. When it is necessary to disassemble the chassis, simply lift the chassis so that the limiting part comes out of the slot, and the chassis can be separated from the inner rail of the slide rail. The operation is simple and efficient.

[0029] In summary, the beneficial effects of this utility model's chassis slide rail mounting structure are as follows: It facilitates installation and disassembly, significantly reducing the difficulty of alignment. Specifically, when using this invention, simply align the limiting part with the mounting part, and the chassis itself will automatically engage, greatly reducing the physical exertion of operators and preventing slide rail jamming or impact damage due to alignment deviations. It is particularly suitable for scenarios with large chassis, heavy weight, and frequent loading and unloading. Disassembly only requires lifting the chassis, further improving operational efficiency. Simultaneously, it significantly improves the universality and interchangeability of slide rail specifications, reducing usage costs. Specifically, the elongated mounting plate has multiple spaced mounting holes, which can accommodate the mounting holes on the inner rails of different specifications of slide rails, eliminating the need for re-drilling or replacing the chassis shell due to changes in slide rail specifications. Furthermore, the spacing between the slots can be flexibly adjusted according to the weight and size of the chassis, adapting to different types of chassis and avoiding cosmetic damage and additional costs caused by specification mismatch.
