Description

Technical Field

[0001] This invention relates to a mechanical connection fastener, and more particularly to a high lateral load riveted spacer assembly. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this invention and does not constitute prior art.

[0003] In the installation of large equipment such as computer rooms, there is a need to connect two relatively far apart plates. Therefore, long spacer columns can be used for support and connection.

[0004] Existing spacer columns mostly adopt a one-piece machining structure. Due to their large length-to-diameter ratio, they are easily limited by tool rigidity and equipment stroke during machining, making it difficult to control the dimensional accuracy of the product. Moreover, slender rods are prone to bending and deformation during transportation and installation. In addition, the connection between traditional spacer columns and the substrate usually relies on a single-point riveting at the root. When the component is subjected to lateral loads or vibration impacts, the stress is highly concentrated at the riveting point, which can easily lead to loosening, tilting, or even breakage at the root of the column, seriously affecting the structural safety of the equipment.

[0005] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0006] The purpose of this invention is to provide a high lateral load riveted spacer assembly that can significantly improve the lateral load-bearing capacity and installation flexibility of large aspect ratio support members through a split assembly structure and additional sleeve support.

[0007] To achieve the above objectives, the present invention discloses a high-side-load riveting spacer assembly having a first end and a second end disposed opposite to each other along the axial direction. The high-side-load riveting spacer assembly is used to connect a first plate and a second plate. The high-side-load riveting spacer assembly includes: A rivet nut, the first end of which is used for riveting connection with the first plate; A sleeve is fixedly disposed on the outside of the rivet nut, and the first end face of the sleeve abuts against the second end face of the first plate; A connecting post, wherein the first end of the connecting post is threadedly connected to the second end of the rivet nut; A locking screw is threaded to the second end of the connecting post and clamps the second plate therebetween.

[0008] As a further description of the above technical solution, the outer wall of the rivet nut is provided with a toothed pattern, and the sleeve is sleeved on the toothed pattern and riveted to the toothed pattern.

[0009] As a further description of the above technical solution, the first end of the riveting nut is provided with a flange, and the second end face of the flange is used to abut against the first end face of the first plate.

[0010] As a further description of the above technical solution, the second end face of the flange is provided with a riveting part protruding in the direction of the second end, and the riveting part is used to pierce the first plate.

[0011] As a further description of the above technical solution, the riveting part is configured as a plurality of ribs extending radially around the riveting nut.

[0012] As a further description of the above technical solution, the riveting part is configured as a toothed structure surrounding the riveting nut.

[0013] As a further description of the above technical solution, the second end of the rivet nut is provided with an internal thread, and the first end of the connecting post is provided with an external thread that mates with the internal thread, so that the rivet nut and the connecting post are connected without gaps.

[0014] As a further description of the above technical solution, the connecting post has a preset length so that the second end face of the connecting post abuts against the first end face of the second plate.

[0015] The present invention also provides an installation method for a high lateral load riveted spacer assembly, comprising the following steps: A first plate is provided, and the first end of the rivet nut is riveted and fixed to the first plate; The sleeve is inserted through the second end of the rivet nut and fixed on the perforated teeth on the outer wall of the rivet nut, such that the first end of the sleeve abuts against the second end face of the first plate. The connecting post is threaded to the second end of the rivet nut; A second plate is provided, which is placed at the second end of the connecting post and locked in place by a locking screw.

[0016] By employing the above technical solutions, the beneficial effects of the present invention are as follows: The high lateral load-bearing riveted spacer assembly of the present invention significantly improves the lateral load-bearing capacity and installation flexibility of large aspect ratio supports through its split-type assembly structure and the support of additional sleeves. Specifically, the present invention adds an additional sleeve outside the riveting nut, so that the first end face of the sleeve forms a large-area abutment support with the surface of the first plate, achieving an additional clamping state for the first plate. This changes the stress model at the root of the traditional support column, effectively dispersing concentrated stress and preventing root fracture or loosening caused by lateral forces under large aspect ratio conditions. At the same time, the present invention uses a split multi-segment structure to decompose the ultra-long support into multiple shorter sub-parts, reducing the difficulty and cost of machining, significantly improving the dimensional accuracy and straightness of the product, and also facilitating stacking protection during logistics transportation.

The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0022] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0023] Please see Figure 1 This embodiment provides a high lateral load riveting spacer assembly, having a first end and a second end arranged axially opposite to each other. The high lateral load riveting spacer assembly is used to connect a first plate 100 and a second plate 200. The high lateral load riveting spacer assembly includes: Riveting nut 1, the first end of which is used for riveting connection with the first plate 100; Sleeve 2, sleeve 2 is fixedly disposed on the outside of the rivet nut 1, and the first end face of sleeve 2 abuts against the second end face of the first plate 100; Connecting post 3, the first end of which is threadedly connected to the second end of the riveting nut 1; The locking screw 4 is threadedly connected to the second end of the connecting post 3 and clamps the second plate 200 therebetween.

[0024] Specifically, in the above structure, the high lateral load riveting spacer assembly is specifically designed to achieve a stable connection and spacing support between the first plate 100 and the second plate 200. In reality, the first plate 100 and the second plate 200 have a considerable distance between them, which could be two adjacent large plates in a device such as a chassis. The first end of the riveting nut 1 is configured to pass through a pre-set mounting hole in the first plate 100 and be riveted to it. The sleeve 2, as a key reinforcing component, is used to increase the contact area and disperse force in the event of lateral load.

[0025] In fact, the connecting column 3 in this invention can be set to multiple as needed, and its length can also be flexibly adjusted according to the spacing requirements.

[0026] Based on the above structure of the present invention, assembly can be achieved through the following installation process. First, a first plate 100 is provided, and the first end of the rivet nut 1 is riveted and fixed to the first plate 100; then, a sleeve 2 is inserted through the second end of the rivet nut 1 and fixed on the perforated teeth 11 on the outer wall of the rivet nut 1, such that the first end of the sleeve 2 abuts against the second end face of the first plate 100; then, the connecting post 3 is threadedly connected to the second end of the rivet nut 1; then, a second plate 200 is provided, the second plate 200 is placed at the second end of the connecting post 3, and the second plate 200 is locked by the locking screw 4.

[0027] In the above installation, a riveting device can be used to initially pierce and rivet the nut 1 to the first plate 100, achieving a stress connection between the two. The sleeve 2 is then inserted through the second end of the nut 1 and pressed and fixed onto the perforated teeth 11 on the outer wall of the nut 1. Similarly, the perforated riveting of the perforated teeth 11 forms a stress connection, ensuring that the first end face of the sleeve 2 tightly abuts against the second end face of the first plate 100, thus completing the root reinforcement. Finally, a suitable connecting post 3 is selected according to the required spacing. After the second plate 200 is placed, the locking screw 4 is passed through the second plate 200 and locked with the connecting post 3, thereby firmly locking the second plate 200, thus achieving the locking connection of the two plates.

[0028] In other words, the lateral load-bearing capacity and installation flexibility of the large length-to-diameter ratio support can be significantly improved through the split-type combined structure and the support of the additional sleeve 2. Specifically, by adding an additional sleeve 2 outside the riveting nut 1, the first end face of the sleeve 2 forms a large-area abutment support with the surface of the first plate 100, realizing an additional clamping state for the first plate 100. This changes the stress model of the traditional support root, effectively dispersing concentrated stress and preventing root breakage or loosening caused by lateral force under large length-to-diameter ratio conditions. At the same time, the split multi-segment structure of the present invention decomposes the ultra-long support into multiple shorter sub-parts, reducing the difficulty and cost of machining, significantly improving the dimensional accuracy and straightness of the product, and also facilitating stacking protection during logistics transportation.

[0029] Furthermore, to ensure the torsional resistance and connection strength between the sleeve 2 and the rivet nut 1, the outer wall of the rivet nut 1 is machined with a specific shape of serrations 11. During installation, the sleeve 2 passes downward from the second end of the rivet nut 1 and is riveted to the serrations 11 by means of interference fit or compression deformation.

[0030] Furthermore, the first end of the rivet nut 1 is designed with a flange 12. The diameter of the flange 12 is larger than the mounting hole diameter on the first plate 100, and its second end face abuts against the first end face of the first plate 100 in the installed state. Through the axial relative arrangement of the flange 12 and the sleeve 2, the first plate 100 is effectively partially clamped between the flange 12 and the sleeve 2. This double-sided clamping structure greatly enhances the rigidity of the connection, ensuring that even in a large aspect ratio support scenario, the root of the component still has extremely high structural stability.

[0031] To further enhance the riveting strength and prevent the rivet nut 1 from rotating or axially dislodging from the first plate 100, a riveting portion 13 protruding towards the second end is provided on the second end face of the flange portion 12. During the riveting process, the riveting portion 13 is subjected to force and penetrates or pierces the material of the first plate 100. This physical embedding can form a very strong mechanical interlocking force, ensuring that the base portion remains stable even when screwed into the connecting column 3 with high torque or subjected to severe vibration. The basic configuration of the riveting portion 13 can be set as follows: Figure 4 The polygonal structure is easy to manufacture.

[0032] Of course, the riveting part 13 can be configured as needed, such as Figure 2 The radial rib structure 131 shown provides excellent torsional resistance after being pressed into the sheet metal. Alternatively, it can be configured as follows: Figure 3 The toothed structure 132 shown creates a uniform gripping force around the mounting holes of the first plate 100 by continuously inserting tooth tips into the plate.

[0033] Furthermore, to ensure the precise positioning of the second plate 200, the axial length of the connecting post 3 is precisely preset according to the pre-defined inter-plate distance. When the connecting post 3 is fully engaged with the rivet nut 1, its second end face has sufficient length to abut against the first end face of the second plate 200, forming a solid supporting surface. Subsequently, by passing the locking screw 4 through the second plate 200 and screwing it into the threaded hole at the top of the connecting post 3, the second plate 200 is firmly pressed against the second end face of the connecting post 3, completing the entire spacing support task.

[0034] The connection between the rivet nut 1 and the connecting post 3 can be configured as a threaded connection that facilitates disassembly and installation. The second end of the rivet nut 1 is provided with an internal thread 14, and the first end of the connecting post 3 is provided with an external thread 31 that mates with the internal thread 14, so that the rivet nut 1 and the connecting post 3 are connected without gaps.

[0035] like Figure 5 As shown, the outer wall of the connecting column 3 can actually be set to hexagon as needed, making it easy to rotate with a socket wrench.
