Description

Technical Field

[0001] The utility model belongs to the technical field of server node installation, in particular to a fool-proof structure for installing a multi-node server. Background Art

[0002] The server has high-speed CPU computing power, long-term reliable operation, strong I / O external data throughput capacity and better scalability. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, provide services, and guarantee services. The server is an important data processing hardware product, which has important application support in the fields of AI intelligence, big data processing, edge computing, etc. Its manufacturing process is complex and the quality control is strict.

[0003] With the continuous development of big data technology and cloud computing technology, high-performance storage and servers are widely needed and applied. Multi-node servers are the typical structure of high-end storage servers. The server nodes have similar configurations, but the installation positions cannot be interchanged. In this way, a fool-proof structure is needed to avoid confusion in the installation position.

[0004] The traditional and commonly used foolproof method for server nodes is to use foolproof PINs that are staggered in vertical height. The foolproof PINs are fixed on the side wall of the chassis, and corresponding long holes are opened on the side wall of the node. The long holes on the side wall of the server node cooperate with the corresponding foolproof PINs on the side wall of the chassis to achieve foolproof installation of the server node. However, this long hole has a great damage to the structural strength of the server node, especially on servers with multiple sets of high-density connectors, which has a great impact on the plug-in of the connectors, seriously affecting the installation accuracy, operation stability and reliability of the server node. Utility Model Content

[0005] In order to solve the problem that the traditional server node installation method uses an anti-fool PIN and a long hole, which greatly damages the structural strength of the server node and seriously affects the installation accuracy and operation stability and reliability of the server node, the utility model provides a multi-node server installation anti-fool structure.

[0006] The utility model is realized by the following technical solutions:

[0007] A fool-proof structure for installing a multi-node server comprises a chassis shell and a plurality of node shells, wherein the chassis shell has chassis side walls positioned and installed on the left and right sides; an elastic hook is positioned and installed on the outer side of the chassis side wall, and an inward hook body is provided at the end of the elastic hook, a through hole for the hook body to pass through is provided on the chassis side wall, and an avoidance hole cooperating with the hook body is provided on the side wall of the node shell, and the avoidance holes on the plurality of node shells are staggered in the vertical direction; the rear edge of the node shell side wall is bent inwardly and provided with a first guide folded edge corresponding to the avoidance hole.

[0008] A further improvement of the utility model is that the avoidance hole is arranged at the rear part of the side wall of the node shell.

[0009] A further improvement of the utility model is that the hook body is in a triangular structure, and the hook body includes a guide edge at the rear side and a barbed edge at the front side.

[0010] A further improvement of the utility model is that the angle between the barbed edge and the side wall of the chassis is not less than 90 degrees, and the distance between the rear edge of the first guide folded edge and the side wall of the chassis is greater than the length of the hook body extending out of the through hole.

[0011] A further improvement of the present invention is that the included angle between the guide edge and the side wall of the chassis is an obtuse angle.

[0012] A further improvement of the utility model is that the hook body and the elastic hook are integrally formed by sheet metal bending.

[0013] A further improvement of the utility model is that the hook body is provided with two upper and lower parts.

[0014] A further improvement of the utility model is that the through hole and the avoidance hole are both rectangular holes.

[0015] A further improvement of the utility model is that the rear edge of the avoidance hole is bent inwardly to provide a second guide folded edge.

[0016] A further improvement of the utility model is that one end of the elastic hook away from the hook body is connected and installed to the side wall of the chassis through at least two rivets.

[0017] It can be seen from the above technical solutions that the beneficial effects of the utility model are:

[0018] When the server node is installed, the node shell is inserted into the corresponding installation space, and the first guide fold is used to press the hook body of the elastic hook, so that the hook body moves outward (retracts into the through hole) to achieve smooth installation of the node shell. When the node shell is inserted into place, the hook body of the elastic hook moves inward (extends out of the through hole) under the action of its own elasticity and is stuck into the avoidance hole of the node shell; when the server node is installed in the wrong position, the first guide fold is misaligned with the hook body in the installation space (up and down), and the stop edge abuts against the hook body, making it impossible to continue installing the server node, thereby achieving a fool-proof effect for the installation of the server node. The overall structure is simple and easy to use, and it will not affect the structural strength of the node shell. It is especially suitable for servers with multiple sets of high-density connectors, ensuring the installation accuracy and stable and reliable operation of the server node.

DETAILED DESCRIPTION

[0025] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0026] like Figure 1-4 As shown, the utility model discloses a fool-proof structure for installing a multi-node server, comprising a chassis shell 4 and a plurality of node shells 1, wherein the chassis shell 4 is provided with chassis side walls 3 positioned and installed on the left and right sides, and the inner side of the chassis side wall 3 is provided with a plurality of guide strips for supporting and guiding the node shell 1; an elastic hook 2 is positioned and installed on the outer side of the chassis side wall 3 (between the chassis side wall 3 and the chassis shell 4), and an inward hook body is provided at the end of the elastic hook 2, and a through hole 32 for the hook body to pass through is provided on the chassis side wall 3, and an avoidance hole 12 cooperating with the hook body is provided on the side wall of the node shell 1, and the avoidance holes 12 on the plurality of node shells 1 are staggered in the vertical direction; the rear edge of the side wall of the node shell 1 is bent inwardly to provide a first guide folded edge 11 corresponding to the avoidance hole 12, and a stop edge 14 is formed at other positions along the rear edge of the side wall of the node shell 1.

[0027] When the server node is installed, the node shell 1 is inserted into the corresponding installation space, and the first guide fold 11 presses the hook body of the elastic hook 2, so that the hook body moves outward (retracts into the through hole 32), and the node shell 1 is smoothly installed. When the node shell 1 is inserted into place, the hook body of the elastic hook 2 moves inward (extends out of the through hole 32) under the action of its own elasticity, and is stuck into the avoidance hole 12 of the node shell 1; and when the server node is installed in the wrong position, the first guide fold 11 is misaligned with the hook body in the installation space (up and down), and the stop edge 14 abuts against the hook body, so that the server node cannot be installed further, thereby achieving a fool-proof effect for the installation of the server node. The overall structure is simple, easy to use, and will not affect the structural strength of the node shell 1. It is especially suitable for servers with multiple groups of high-density connectors, ensuring the installation accuracy and stable and reliable operation of the server node.

[0028] The avoidance hole 12 is arranged at the rear of the side wall of the node housing 1. Before the server node is installed in place, foolproofing is achieved to ensure the reliability of the early installation of the server node and prevent the server node from falling.

[0029] Among them, Figure 2-3As shown, the hook body is in a triangular structure, and the hook body includes a guide edge 23 at the rear side and a hook edge 22 at the front side. The angle between the hook edge 22 and the chassis side wall 3 is not less than 90 degrees (preferably 90 degrees), and the distance between the rear edge of the first guide folded edge 11 and the chassis side wall 3 is greater than the length of the hook body extending out of the through hole 32. When the first guide folded edge 11 contacts the hook edge 22 of the hook body, it effectively ensures that the first guide folded edge 11 can press the hook body smoothly, thereby ensuring the smooth installation of the server node.

[0030] Among them, Figure 2-3 As shown, the hook body and the elastic hook 2 are formed by bending a sheet metal, and the hook body is provided with two upper and lower parts. The through hole 32 and the avoidance hole 12 are both rectangular holes. The structure is simple, the forming is easy, and the influence on the structural strength of the chassis side wall 3 and the node housing 1 is effectively reduced.

[0031] Among them, Figure 3 As shown, the included angle between the guide edge 23 and the chassis side wall 3 is an obtuse angle, and is preferably 135 degrees, which effectively ensures the smoothness of the server node when it is pulled out and avoids jamming.

[0032] Further, such as Figure 2-3 As shown, in order to improve the smoothness of pulling out the server node, the rear edge of the avoidance hole 12 is bent inward to provide a second guide folded edge 13, and the second guide folded edge 13 presses the guide edge 23 to conveniently achieve the retraction of the hook body.

[0033] The end of the elastic hook 2 away from the hook body is connected to the side wall 3 of the chassis through at least two rivets 31. The elastic hook 2 is provided with a mounting hole 21 for the rivets 31 to pass through. The elastic hook 2 is easy to install, occupies little space, and does not affect the normal structural layout.

[0034] The present multi-node server installation fool-proof structure, when the server node is installed, the node shell 1 is inserted into the corresponding installation space, and the first guide fold 11 presses the hook body of the elastic hook 2, so that the hook body moves outward (retracts into the through hole 32), and the node shell 1 is smoothly installed. When the node shell 1 is inserted into place, the hook body of the elastic hook 2 moves inward (extends out of the through hole 32) under the action of its own elasticity, and is stuck into the avoidance hole 12 of the node shell 1; and when the server node is installed in the wrong position, the first guide fold 11 is misaligned with the hook body in the installation space (up and down), and the stop edge 14 abuts against the hook body, so that the server node cannot be installed further, thereby achieving the fool-proof effect of server node installation. The overall structure is simple, easy to use, and will not affect the structural strength of the node shell 1. It is especially suitable for servers with multiple groups of high-density connectors, ensuring the installation accuracy and stable and reliable operation of the server node.
