Description

Technical Field

[0001] This utility model relates to the field of KVM switch technology, specifically a portable KVM switch. Background Technology

[0002] A KVM switch is a computer peripheral hardware device that allows system administrators to control multiple PCs or servers using a set of keyboard, mouse, and monitor. The main principle of a KVM switch is to use a digital signal converter (DSC) and a multiplexer (MUX) to switch between different computers.

[0003] For example, the patent application number published on the China Patent Network is 202321414448.9, and the patent name is: A KVM switch with easy heat dissipation. It includes a support base plate and a KVM switch. A high-efficiency heat dissipation adjustment mechanism is set between the support base plate and the KVM switch. A temperature sensor is installed on the inner wall of the KVM switch, and a controller is installed on the bottom inner side of the KVM switch. The bottom of the KVM switch is fixedly connected to the output end of a cylinder. When the temperature is high, the controller can control the cylinder to lift the KVM switch upward. Since the heat dissipation component is set on the bottom inner side of the KVM switch and opposite to the sides of the controller, and the auxiliary heat conduction component is set on the side wall of the KVM switch, the heat dissipation effect of the heat dissipation component is better when the bottom of the KVM switch is raised, thereby improving the heat dissipation effect. The controller controls the cooling fan to work, so that the internal temperature of the KVM switch can be quickly discharged. The power of the cooling fan can also be adjusted according to the internal temperature.

[0004] However, the connection ends of existing KVM switches are generally directly exposed to the external environment. During the process of carrying and moving, the exposed connection ends are not only affected by the external environment, but also prone to deformation when they collide with external devices, which seriously affects the performance.

[0005] Therefore, the portable KVM switch needs to be redesigned and modified. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a portable KVM switch that has the advantage of being easy to protect during transport. This solves the problem that the connection ends of existing KVM switches are generally directly exposed to the external environment. During transport and movement, the exposed connection ends are not only affected by the external environment, but also easily deformed when they collide with external devices, which seriously affects the performance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable KVM switch, comprising a body;

[0008] Interfaces that are electrically connected to both sides of the machine body;

[0009] Connecting blocks are fixedly connected to the left and right sides of the machine body. A baffle is movably connected to the inner side of the connecting block via a pin. The side of the baffle away from the connecting block extends to the front and rear sides of the machine body. The interface is located inside the baffle and the baffle can cover the interface. A fixing structure is provided on the top of the machine body. The fixing structure can position the baffle after it swings.

[0010] As a preferred embodiment of this utility model, the fixing structure includes movable blocks fixedly connected to the four corners of the top of the machine body. The inner side of the movable block is movably connected to a shaft through a bearing. Both sides of the shaft surface are fixedly connected to pressure plates. The side of the pressure plate away from the shaft extends to the outside of the baffle and contacts the baffle. The top of the machine body is provided with a transmission structure, which can control the shaft to carry the pressure plate to rotate and swing and squeeze the baffle.

[0011] In a preferred embodiment of this utility model, the transmission structure includes a bracket fixedly connected to the top of the machine body. A threaded assembly is movably connected to the inner side of the bracket via a bearing. A handle located inside the bracket is fixedly connected to the surface of the threaded assembly. Both ends of the threaded assembly are threadedly connected to transmission plates. An extrusion frame is fixedly connected to the outer side of the transmission plate. A force-bearing plate located outside the extrusion frame is fixedly connected to the surface of the shaft. The outer side of the extrusion frame is in contact with the surface of the force-bearing plate.

[0012] As a preferred embodiment of this utility model, a guide rod is fixedly connected to the inner side of the transmission plate, and the side of the guide rod away from the transmission plate passes through the bracket and is slidably connected to the bracket.

[0013] As a preferred embodiment of this utility model, a spring plate is fixedly connected to the inner side of the pressure plate. The side of the spring plate away from the pressure plate is in contact with the surface of the interface. A groove is provided on the side of the spring plate near the interface, and the groove can accommodate the cable connector that is connected to the interface.

[0014] As a preferred embodiment of this invention, the inner part of the spring plate is fixedly connected with a rubber pad, which can buffer the spring plate after bending and deformation and cover the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a movable baffle that connects to the machine body via a connecting block and a pin. This baffle can cover the interfaces on both sides of the machine body, which is not only aesthetically pleasing but also effectively prevents dust and debris from entering the interfaces and protects them from physical damage. At the same time, the baffle design makes it easy for users to open it during use and connect cables.

[0017] 2. This utility model achieves the fixation of the baffle through a movable block, a shaft and a pressure plate. When the baffle is opened to the desired position, the pressure plate can rotate and swing to squeeze the baffle, thereby fixing it. It is not only simple and practical, but also ensures that the baffle remains stable in the open state and is not easily closed by external force.

[0018] 3. This utility model achieves control of the pressure plate through the cooperation of the threaded assembly, transmission plate, extrusion frame and force plate. The user only needs to rotate the handle, and the threaded assembly will drive the transmission plate to move, which in turn pushes the force plate through the extrusion frame, causing the shaft and pressure plate to rotate and swing, thus achieving precise adjustment and control.

[0019] 4. This utility model, through the design of the guide rod on the inner side of the transmission plate, not only enhances the stability of the transmission structure, but also ensures the straightness of the transmission plate during movement. The guide rod passes through the bracket and slides through the bracket, which can effectively prevent the transmission plate from shifting or shaking during movement, thereby improving the reliability and durability of the entire KVM switch.

[0020] 5. This utility model, through the spring plate design on the inner side of the pressure plate, not only increases the contact area between the pressure plate and the interface, improving the stability of the fixation, but also accommodates the cable connector connected to the interface through the groove. This effectively prevents the cable connector from being damaged or falling off during the connection process.

[0021] 6. The rubber pad design inside the spring plate not only provides a buffer when the spring plate is bent and deformed, protecting it from damage, but also covers the groove to prevent dust and debris from entering, further improving the dustproof performance and durability of the KVM switch, while also providing users with a more comfortable and convenient user experience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, the present invention provides a portable KVM switch, including a body 1;

[0029] Interfaces 2 are electrically connected to both sides of the body 1;

[0030] Connecting blocks 3 are fixedly connected to the left and right sides of the body 1. A baffle 4 is movably connected to the inner side of the connecting block 3 via a pin. The side of the baffle 4 away from the connecting block 3 extends to the front and rear sides of the body 1. The interface 2 is located inside the baffle 4 and the baffle 4 can block the interface 2. A fixing structure 5 is provided on the top of the body 1. The fixing structure 5 can position the baffle 4 after it swings.

[0031] refer to Figure 3 The fixed structure 5 includes movable blocks 6 fixedly connected to the four corners of the top of the machine body 1. The inner side of the movable block 6 is movably connected to the shaft 7 through bearings. Both sides of the surface of the shaft 7 are fixedly connected to the pressure plate 8. The side of the pressure plate 8 away from the shaft 7 extends to the outside of the baffle 4 and contacts the baffle 4. The top of the machine body 1 is provided with a transmission structure 9. The transmission structure 9 can control the shaft 7 to carry the pressure plate 8 to rotate and swing and squeeze the baffle 4.

[0032] As a technical optimization of this utility model, the baffle 4 is fixed by the movable block 6, the shaft 7 and the pressure plate 8. When the baffle 4 is opened to the required position, the pressure plate 8 can rotate and swing to squeeze the baffle 4, thereby fixing it. This is not only simple and practical, but also ensures that the baffle 4 remains stable in the open state and is not easily closed by external force.

[0033] refer to Figure 4The transmission structure 9 includes a bracket 10 fixedly connected to the top of the body 1. A threaded assembly 11 is movably connected to the inner side of the bracket 10 via a bearing. A handle 12 located inside the bracket 10 is fixedly connected to the surface of the threaded assembly 11. Both ends of the threaded assembly 11 are threadedly connected to a transmission plate 13. A pressing frame 14 is fixedly connected to the outer side of the transmission plate 13. A force-bearing plate 15 located outside the pressing frame 14 is fixedly connected to the surface of the shaft 7. The outer side of the pressing frame 14 is in contact with the surface of the force-bearing plate 15.

[0034] As a technical optimization of this utility model, the control of the pressure plate 8 is realized through the cooperation of the threaded assembly 11, the transmission plate 13, the extrusion frame 14 and the force plate 15. The user only needs to rotate the handle 12, and the threaded assembly 11 will drive the transmission plate 13 to move, and then push the force plate 15 through the extrusion frame 14, so that the shaft 7 and the pressure plate 8 can rotate and swing, thus achieving precise adjustment and control.

[0035] refer to Figure 4 A guide rod 16 is fixedly connected to the inner side of the transmission plate 13. The side of the guide rod 16 away from the transmission plate 13 passes through the bracket 10 and is slidably connected to the bracket 10.

[0036] As a technical optimization of this utility model, the design of the guide rod 16 on the inner side of the transmission plate 13 not only enhances the stability of the transmission structure 9, but also ensures the straightness of the transmission plate 13 during movement. The guide rod 16 passes through the bracket 10 and is slidably connected to the bracket 10, which can effectively prevent the transmission plate 13 from shifting or shaking during movement, thereby improving the reliability and durability of the entire KVM switch.

[0037] refer to Figure 4 A spring plate 17 is fixedly connected to the inner side of the pressure plate 8. The side of the spring plate 17 away from the pressure plate 8 contacts the surface of the interface 2. A groove 18 is provided on the side of the spring plate 17 close to the interface 2. The groove 18 can accommodate the cable connector that is connected to the interface 2.

[0038] As a technical optimization of this utility model, the design of the spring plate 17 on the inner side of the pressure plate 8 not only increases the contact area between the pressure plate 8 and the interface 2, improving the stability of the fixation, but also accommodates the cable connector connected to the interface 2 through the groove 18. This effectively prevents the cable connector from being damaged or falling off during the connection process.

[0039] refer to Figure 3 The spring plate 17 is internally fixedly connected with a rubber pad 19, which can buffer the spring plate 17 after it is bent and deformed and cover the groove 18.

[0040] As a technical optimization of this utility model, the rubber pad 19 inside the spring plate 17 not only provides a buffer when the spring plate 17 is bent and deformed, protecting the spring plate 17 from damage, but also covers the groove 18 to prevent dust and debris from entering, further improving the dustproof performance and durability of the KVM switch, while also providing users with a more comfortable and convenient user experience.

[0041] The working principle and usage process of this utility model: The body 1 is the core part of the KVM switch. Interfaces 2 are electrically connected to both sides of the body 1 for connecting to different computers or devices. Connecting blocks 3 are fixed on the left and right sides of the body 1. These connecting blocks 3 are movably connected to baffles 4 via pins. Baffles 4 can swing around the pins, and their extensions can cover the front and rear sides of the body 1, especially the interface 2, thus providing a certain degree of protection and dustproof effect. When the baffles 4 are installed, the handle 12 is rotated synchronously, and the threaded assembly 11 drives the transmission plate 13 to move. A compression frame 14 is fixed to the outer side of the transmission plate 13, and a force-bearing plate 15 is fixed to the shaft 7. As the transmission plate 13 moves, the pressing frame 14 presses the force plate 15, causing the shaft 7 and the pressure plate 8 to rotate and swing. During the swing, the pressure plate 8 presses the baffle 4 to prevent the baffle 4 from disengaging from the interface 2. When the interface 2 needs to be used, the handle 12 is operated in the opposite direction. As the transmission plate 13 moves, the pressing frame 14 disengages from the force plate 15, causing the shaft 7 and the pressure plate 8 to rotate and swing. During the swing, the pressure plate 8 disengages from the baffle 4, causing the baffle 4 to swing around the pin and open, exposing the interface 2. Then, the user plugs in the data connector and, after plugging in, uses the spring plate 17 to press and position the data connector to ensure connection stability.

[0042] In summary, this portable KVM switch, with its movable baffle 4 connected to the body 1 via connecting block 3 and pin, can cover the interfaces 2 on both sides of the body 1. This not only improves aesthetics but also effectively prevents dust and debris from entering the interfaces 2, protecting them from physical damage. At the same time, the baffle 4 is designed to be easy for users to open during use, facilitating cable connection.
