Description

Technical Field

[0001] This invention relates to the field of network switch technology that is easy to maintain, specifically to a network switch that is easy to maintain. Background Technology

[0002] With the rapid development of information and communication technologies, network switches, as core devices in data communication networks, are widely used in enterprises, data centers, and various communication systems. To achieve centralized management and maintenance of network equipment, switches are typically installed in standard cabinets and positioned using mounting rails, screws, and other fixing methods.

[0003] However, traditional switches are typically fixed to the rack using screws or clips, requiring screwdrivers and other tools for disassembly. This process is particularly time-consuming and inefficient, especially in environments with dense equipment deployments. Specifically, maintenance personnel often have to frequently tighten screws in tight corners or pry open clips within the limited rack space. This can easily lead to misoperation due to obstructed vision and uneven force, potentially deforming the equipment or rack rails. Furthermore, the dense cabling and tangled labels mean that even a slight mishap can pull on the power or network cables of adjacent devices, causing secondary malfunctions. When multiple switches in a data center need to be upgraded or replaced simultaneously, this process of "loosening screws one by one—lifting the equipment—avoiding cables—removing the chassis" must be repeated repeatedly, often taking several hours. This not only increases labor costs but also extends business downtime, failing to meet the urgent needs of modern data centers for high availability, rapid iteration, and ease of maintenance.

[0004] Therefore, existing technologies still have significant shortcomings in the installation, disassembly, and daily maintenance of network switches. There is an urgent need for a switch installation solution that is structurally sound, easy to operate, and convenient to maintain, in order to improve the efficiency and reliability of equipment management. Summary of the Invention

[0005] The purpose of this invention is to provide a network switch that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A support plate is provided at the bottom center of the switch body, and an opening and closing screw is rotatably connected to the support plate. The opening and closing screw is split in the middle, and the threads on both sides are opposite. T-shaped plates are threaded to both sides of the opening and closing screw. First telescopic grooves are provided at both ends of the T-shaped plates. First telescopic columns are elastically connected in the first telescopic grooves. Limiting plates are provided at the outer ends of the first telescopic columns, and fixed plugs are provided on the outer sides of the limiting plates.

[0007] Preferably, the T-shaped plate has a threaded through hole in the middle, and the T-shaped plate is threaded to both ends of the opening and closing screw through the threaded through hole. An adjustment knob is provided in the middle of the opening and closing screw. Turning the adjustment knob can drive the T-shaped plate to open and close on both sides of the opening and closing screw.

[0008] Preferably, the T-shaped plate has first telescopic grooves on both sides, and a first spring is provided in the first telescopic groove. One end of the first spring is connected to the inner wall of the first telescopic groove, and the other end of the first spring is connected to the first telescopic column. The first spring can drive the first telescopic column to extend and retract in the first telescopic groove.

[0009] Preferably, the end of the first telescopic column is connected to an L-shaped plate inside the switch body. The L-shaped plate extends out from the through groove opened inside the first telescopic groove of the T-shaped plate. A second telescopic groove is opened at the bottom of the vertical rod of the extended L-shaped plate, and the second telescopic column is elastically connected in the second telescopic groove.

[0010] Preferably, a second spring is provided in the second telescopic groove, the top of the second spring is connected to the inner wall of the second telescopic groove, and the bottom of the second spring is connected to the second telescopic column. The second spring can drive the second telescopic column to extend and retract in the second telescopic groove.

[0011] Preferably, in the second telescopic column, the bottom inner side of the two sets of second telescopic columns in the longitudinal direction is provided with a second sleeve plate and a second plug plate respectively. The second plug plate is inserted into the second sleeve plate, and multiple sets of limiting holes are opened on the second sleeve plate and the second plug plate.

[0012] Preferably, the bottom of the T-shaped plate is provided with a limiting post at a position parallel to the limiting hole opened on the second sleeve plate and the second plug-in plate, and the limiting post can be inserted into the limiting hole that coincides with the second sleeve plate and the second plug-in plate.

[0013] Preferably, the bottom longitudinal inner side of the two sets of second telescopic columns in the lateral direction is closedly connected to the first sleeve plate and the first plug-in plate, and the first sleeve plate is inserted into the first plug-in plate.

[0014] Preferably, the second telescopic column, the first sleeve plate, the second sleeve plate, and the second plug plate form a telescopic rectangular frame located at the bottom of the switch body.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention proposes a network switch that is easy to maintain. When the switch body is installed on a cabinet support column, it is placed in the middle of four sets of cabinet support columns. First, according to the lateral spacing of the cabinet support columns, the adjustment knob located in the middle of the opening and closing screw at the bottom of the switch body is turned. The adjustment knob drives the opening and closing screw to rotate. The adjustment knob drives the threaded through hole on both sides of the opening and closing screw to move open and close, so that the fixing plug of the outer end of the limiting plate of the first telescopic column inserted in the first telescopic groove at both ends of the T-shaped plate can be parallel to the fixing hole on the cabinet support column. Then, by pulling down the first sleeve plate and the first plug plate, the first sleeve plate and the first plug plate pull the second telescopic column downward. The second telescopic column moves downward, driving the second sleeve plate and the second plug plate to move downward synchronously. This causes the bottom limiting column of the T-shaped plate to disengage from the corresponding vertical limiting hole of the second sleeve plate and the second plug plate. At this time, the first spring in the first telescopic groove on both sides of the T-shaped plate pushes the first telescopic column outward by a distance through tension, so that the limiting plate is held against the fixing hole on the parallel cabinet support column. Inside the fixed hole, the fixed plug is inserted into the corresponding fixed hole to fix the switch body to the cabinet column. Then, release the pull and pull down the first sleeve plate and the first plug plate. At this time, the second telescopic column drives the second sleeve plate and the second plug plate to reset through the contraction force, so that the bottom limiting post of the T-shaped plate is inserted again into the limiting hole opened on the corresponding second sleeve plate and the second plug plate perpendicular to it, fixing the telescopic movement of the second sleeve plate and the second plug plate, so that the second sleeve plate and the second plug plate synchronously fix the telescopic movement of the first telescopic column in the first telescopic groove. Once the switch body is fixed, the installation is complete. When it is necessary to remove the switch body from the cabinet column, pull down the first sleeve plate and the first plug plate again to disengage the limiting post from the limiting hole. Then, push the two sets of second telescopic posts and the first plug plate towards the middle of the switch body. At this time, the second plug plate extends and retracts in the second sleeve plate, while simultaneously causing the first telescopic post to retract in the first telescopic groove. This causes the limiting plate at the outer end of the first telescopic post to fall off and hold against the inside of the fixing hole. The fixing plug disengages from the fixing hole, and the switch body can be removed from the cabinet column. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 5 The present invention provides a technical solution: A support plate 2 is provided at the bottom center of the switch body 1. An opening and closing screw 3 is rotatably connected to the support plate 2. The opening and closing screw 3 is split in the middle with opposite threads on both sides. T-shaped plates 5 are threaded to both sides of the opening and closing screw 3. First telescopic grooves 7 are provided at both ends of the T-shaped plates 5. First telescopic columns 9 are elastically connected in the first telescopic grooves 7. Limiting plates 10 are provided at the outer ends of the first telescopic columns 9. Fixing plugs 11 are provided on the outer sides of the limiting plates 10. The fixing plugs 11 at the outer ends of the limiting plates 10 of the first telescopic columns 9 inserted into the first telescopic grooves 7 at both ends of the T-shaped plates 5 can be parallel to the fixing holes 23 on the upright column 22 of the cabinet.

[0020] The T-shaped plate 5 has a threaded through hole 6 in the middle. The T-shaped plate 5 is threaded to both ends of the opening and closing screw 3 through the threaded through hole 6. The opening and closing screw 3 has an adjustment knob 4 in the middle. Turning the adjustment knob 4 can drive the T-shaped plate 5 to open and close on both sides of the opening and closing screw 3. The T-shaped plate 5 has a first telescopic groove 7 on both sides. The first telescopic groove 7 is equipped with a first spring 8. One end of the first spring 8 is connected to the inner wall of the first telescopic groove 7, and the other end of the first spring 8 is connected to the first telescopic column 9. The first spring 8 can drive the first telescopic column 9 to extend and retract in the first telescopic groove 7. The first spring 8 in the first telescopic groove 7 on both sides of the T-shaped plate 5 pushes the first telescopic column 9 outward by a distance through tension, so that the limiting plate 10 is held against the inside of the fixing hole 23 on the cabinet column 22 parallel to it. The fixing plug 11 is inserted into the corresponding fixing hole 23 to fix the switch body 1 to the cabinet column 22.

[0021] The end of the first telescopic column 9 is connected to an L-shaped plate 12 inside the switch body 1. The L-shaped plate 12 extends out from the through slot opened inside the first telescopic groove 7 by the T-shaped plate 5. The bottom of the vertical rod of the extended L-shaped plate 12 is provided with a second telescopic groove 13. The second telescopic column 15 is elastically connected in the second telescopic groove 13. A second spring 14 is provided in the second telescopic groove 13. The top of the second spring 14 is connected to the inner wall of the second telescopic groove 13, and the bottom of the second spring 14 is connected to the second telescopic column 15. The second spring 14 can drive the second telescopic column 15 to extend and retract in the second telescopic groove 13. The first sleeve plate 16 and the first plug plate 17 pull the second telescopic column 15 to extend and retract downward. The second telescopic column 15, by extending and retracting downward, drives the second sleeve plate 18 and the second plug plate 19 to extend and retract downward synchronously.

[0022] The second telescopic column 15 has two sets of longitudinal second telescopic columns 15 with a second sleeve plate 18 and a second plug plate 19 respectively provided on the inner side of the bottom. The second plug plate 19 is inserted into the second sleeve plate 18. Multiple sets of limiting holes 20 are opened on the second sleeve plate 18 and the second plug plate 19. The bottom of the T-shaped plate 5 is provided with a limiting post 21 at a position parallel to the limiting holes 20 opened on the second sleeve plate 18 and the second plug plate 19. The limiting post 21 can be inserted into the limiting hole 20 that coincides with the second sleeve plate 18 and the second plug plate 19. The second telescopic column 15 drives the second sleeve plate 18 and the second plug plate 19 to reset by contraction force, so that the limiting post 21 at the bottom of the T-shaped plate 5 is inserted again into the limiting hole 20 opened on the corresponding second sleeve plate 18 and the second plug plate 19 perpendicular to it.

[0023] The bottom of the two sets of second telescopic columns 15 in the horizontal direction is longitudinally and internally connected to the first sleeve plate 16 and the first plug plate 17. The first sleeve plate 16 is inserted into the first plug plate 17. The second telescopic columns 15, the first sleeve plate 16, the second sleeve plate 18, and the second plug plate 19 form a telescopic rectangular frame located at the bottom of the switch body 1. Pulling down the first sleeve plate 16 and the first plug plate 17 causes the limiting column 21 to disengage from the limiting hole 20. Then, by pushing the two sets of second telescopic columns 15 and the first plug plate 17 towards the middle of the switch body 1, the second plug plate 19 extends and retracts in the second sleeve plate 18, while simultaneously causing the first telescopic column 9 to retract in the first telescopic groove 7.

[0024] In actual use, when installing the switch body 1 on the cabinet upright 22, place the switch body 1 in the middle of the four sets of cabinet uprights 22. First, according to the lateral spacing of the cabinet uprights 22, turn the adjustment knob 4 located in the middle of the bottom opening and closing screw 3 of the switch body 1. The adjustment knob 4 drives the opening and closing screw 3 to rotate. The adjustment knob 4 drives the threaded through hole 6 to open and close on both sides of the opening and closing screw 3, so that the fixing plug 11 of the outer end of the limiting plate 10 of the first telescopic column 9 inserted into the first telescopic groove 7 at both ends of the T-shaped plate 5 can be parallel to the fixing hole 23 on the cabinet upright 22. Then, pull down... The first sleeve plate 16 and the first plug-in plate 17 are moved, causing the first sleeve plate 16 and the first plug-in plate 17 to pull the second telescopic column 15 downward. The second telescopic column 15, by extending and retracting downward, drives the second sleeve plate 18 and the second plug-in plate 19 to extend and retract downward synchronously, causing the bottom limiting post 21 of the T-shaped plate 5 to disengage from the corresponding vertical limiting hole 20 of the second sleeve plate 18 and the second plug-in plate 19. At this time, the first spring 8 in the first telescopic groove 7 on both sides of the T-shaped plate 5, through tension, pushes the first telescopic column 9 outward by a certain distance, so that the limiting plate 10 is held against the inside of the fixing hole 23 on the parallel cabinet column 22, fixing the plug 1. 1. Insert the switch body 1 into the corresponding fixing hole 23 to fix it onto the cabinet column 22. Then, release and pull down the first sleeve plate 16 and the first plug plate 17. At this time, the second telescopic column 15 drives the second sleeve plate 18 and the second plug plate 19 to reset through the contraction force, so that the bottom limiting column 21 of the T-shaped plate 5 is inserted again into the limiting hole 20 opened on the corresponding second sleeve plate 18 and the second plug plate 19 perpendicular to it. The telescopic fixation of the second sleeve plate 18 and the second plug plate 19 is fixed, so that the second sleeve plate 18 and the second plug plate 19 synchronously fix the telescopic column 9 in the first telescopic groove 7, thus completing the process. Installation: When it is necessary to remove the switch body 1 from the cabinet column 22, pull down the first sleeve plate 16 and the first plug plate 17 again to disengage the limiting post 21 from the limiting hole 20. Then, push the two sets of second telescopic posts 15 and the first plug plate 17 towards the middle of the switch body 1. At this time, the second plug plate 19 extends and retracts in the second sleeve plate 18, and at the same time, it drives the first telescopic post 9 to retract in the first telescopic groove 7. This causes the limiting plate 10 at the outer end of the first telescopic post 9 to fall off and hold against the inner side of the fixing hole 23. The fixing plug 11 disengages from the fixing hole 23, and the switch body 1 can be removed from the cabinet column 22.
