Description

Technical Field

[0001] This utility model relates to the field of shielding cover technology, and in particular to an easily detachable shielding cover. Background Technology

[0002] A shielding cover is a metal or metallized component used in electronic devices. It is usually made of materials with good electromagnetic shielding properties, such as copper, aluminum, or iron-nickel alloys. It can prevent electromagnetic radiation generated by internal electronic components from leaking into the external environment, avoiding electromagnetic interference to other electronic devices in the vicinity. At the same time, it can also prevent external electromagnetic signals from entering the device, preventing interference to sensitive internal electronic components and ensuring the normal operation of the device.

[0003] Existing shielding covers are generally installed on the shielding shell using screws or other rigid connection methods. This means that the shielding cover needs to be tightened one by one during installation and unscrewed one by one during disassembly. The process is cumbersome and time-consuming. This is especially true for some large equipment or electronic devices with complex internal structures, where there are many screws, making the time cost of installation and disassembly even higher. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the connection method between the shielding cover and the shielding shell in the existing technology is relatively complicated, which makes it time-consuming to install and disassemble. Therefore, we propose an easily detachable shielding cover.

[0005] To achieve the above objectives, this application adopts the following technical solution: an easily detachable shielding cover, comprising a shielding shell, a shielding cover body installed at the bottom of the shielding shell, four fixing plates fixedly connected to the top of the shielding cover body, a limiting port opened on the surface of the fixing plate, four fixing blocks installed on the surface of the shielding shell, a pressing groove opened inside the fixing block, a spring fixedly connected inside the pressing groove, a pressing block fixedly connected to the end of the spring, and the limiting port and the inside of the pressing groove are slidably connected to the pressing block.

[0006] Preferably, a stop groove is provided on both sides of the inside of the pressing groove, and a stop block is fixedly connected to both sides of the pressing block, and the inside of the stop groove is slidably connected to the stop block.

[0007] Preferably, the surface of the pressing block has an inclined surface.

[0008] Preferably, the bottom of the shielding shell is provided with four guide grooves, and the top of the shielding cover body is provided with four guide blocks, and the interior of the guide grooves is slidably connected to the guide blocks.

[0009] Preferably, the shielding shell is provided with glass observation windows at both the front and rear ends, and the surface of the glass observation windows is covered with a transparent metal film.

[0010] Preferably, the top of the shielding shell is equipped with heat dissipation fins, and the number of heat dissipation fins is several and evenly distributed on the top of the shielding shell.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, when the operator needs to remove the shielding cover body, pressing the four pressing blocks inward simultaneously releases the shielding cover body from the shielding shell, allowing the shielding cover body to be removed. When the shielding cover body needs to be reinstalled on the shielding shell, the pressing blocks are pressed inward again to align and fit the shielding shell and shielding cover body. After completion, the elastic spring force causes the pressing blocks to pop out into the limiting slot, achieving rapid fixation between the shielding shell and the shielding cover body. With the shielding cover body that can be quickly installed and removed, when electronic equipment malfunctions, technicians can quickly remove the shielding cover body from the shielding shell to quickly locate and repair internal electronic components without spending a lot of time dismantling complex fixing structures, thereby shortening maintenance time and improving equipment availability.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] Reference Figures 1-4As shown, this utility model provides a technical solution: an easily detachable shielding cover, including a shielding shell 1, a shielding cover body 2 installed at the bottom of the shielding shell 1, four fixing plates 3 fixedly connected to the top of the shielding cover body 2, limit openings 4 on the surface of the fixing plates 3, four fixing blocks 5 installed on the surface of the shielding shell 1, pressing grooves 6 opened inside the fixing blocks 5, spring springs 7 fixedly connected inside the pressing grooves 6, and pressing blocks 8 fixedly connected to the ends of the spring springs 7. The limit openings 4 and the interiors of the pressing grooves 6 are slidably connected to the pressing blocks 8. When the operator needs to remove the shielding cover body 2, the four pressing blocks 8 are pressed inward simultaneously, which allows the shielding cover body 2 to detach from the shielding shell 1. Once the shielding shell 1 is released from its fixed position, the shielding cover body 2 can be removed. When it is necessary to reinstall the shielding cover body 2 back onto the shielding shell 1, press the pressing block 8 inward again to align and fit the shielding shell 1 and the shielding cover body 2. After completion, the elastic force of the spring spring 7 will cause the pressing block 8 to pop out into the limiting port 4, achieving quick fixation between the shielding shell 1 and the shielding cover body 2. With the shielding cover body 2, which can be quickly installed and removed, technicians can quickly remove the shielding cover body 2 from the shielding shell 1 when electronic equipment malfunctions, quickly locate and repair the internal electronic components, without spending a lot of time dismantling the complex fixing structure, thereby shortening the maintenance time and improving the availability of the equipment.

[0020] Reference Figure 4 As shown in this embodiment: both sides of the inside of the pressing groove 6 are provided with stop grooves 9, and both sides of the pressing block 8 are fixedly connected with stop blocks 10. The inside of the stop groove 9 is slidably connected with the stop block 10. Through the setting of the stop groove 9 and the stop block 10, when the spring spring 7 drives the pressing block 8 to pop out into the limit port 4, the movement trajectory of the pressing block 8 can be effectively limited, and the situation of excessive popping out will not occur, thereby making the fixing process of the shielding shell 1 and the shielding cover body 2 more stable.

[0021] Reference Figure 3 As shown in this embodiment: the surface of the pressing block 8 is provided with a bevel 11. With the setting of the bevel 11, when it is necessary to fix the shielding shell 1 and the shielding cover body 2, it is only necessary to align the shielding cover body 2 with the shielding shell 1 and fit it. The pressing block 8 can automatically slide into the limiting port 4 and pop out and snap, so as to achieve the rapid installation of the shielding cover body 2 and further improve the operating efficiency.

[0022] Reference Figure 3As shown in this embodiment: the bottom end of the shielding shell 1 is provided with four guide grooves 12, and the top end of the shielding cover body 2 is provided with four guide blocks 13. The inside of the guide grooves 12 is slidably connected with the guide blocks 13. Through the setting of the guide grooves 12 and the guide blocks 13, the shielding cover body 2 and the shielding shell 1 can be automatically aligned during the fitting and installation process, so that the shielding cover body 2 will not be offset during the installation process, effectively ensuring the stability of the shielding function and the installation efficiency.

[0023] Reference Figure 2 As shown in this embodiment: both the front and rear ends of the shielding shell 1 are provided with glass observation windows 14. The surface of the glass observation windows 14 is covered with a transparent metal film. Through the glass observation windows 14 covered with a transparent metal film, the operator can easily observe the working status of the electronic components or circuits inside the shielding shell 1 and the shielding cover body 2, such as the on and off of indicator lights and the operation of components, without having to disassemble the shielding cover body 2, which facilitates the debugging, maintenance and troubleshooting of the equipment.

[0024] Reference Figure 3 As shown in this embodiment: heat dissipation fins 15 are installed on the top of the shielding shell 1. The number of heat dissipation fins 15 is several and they are evenly distributed on the top of the shielding shell 1. By setting multiple heat dissipation fins 15 on the top of the shielding shell 1, the heat dissipation area of ​​the shielding shell 1 can be effectively increased, the heat dissipation efficiency can be improved, and the shielded electronic components or circuits can be better cooled to prevent performance or lifespan from being affected by overheating.

[0025] Working principle: When the operator needs to remove the shielding cover body 2, the four pressing blocks 8 are pressed inward simultaneously to release the shielding cover body 2 from the shielding shell 1, allowing the shielding cover body 2 to be removed. When it is necessary to reinstall the shielding cover body 2 onto the shielding shell 1, the pressing blocks 8 are pressed inward again to align and fit the shielding shell 1 and the shielding cover body 2. After completion, the elastic force of the spring spring 7 causes the pressing blocks 8 to pop out into the limiting port 4, achieving quick fixation between the shielding shell 1 and the shielding cover body 2. Through the quick-installation and removal of the shielding cover body 2, in electronic... When equipment malfunctions, technicians can quickly remove the shielding cover body 2 from the shielding shell 1, rapidly locate and repair internal electronic components, without spending significant time dismantling complex fixing structures. This shortens repair time and improves equipment availability. Through the placement of the stop groove 9 and stop block 10, when the spring spring 7 pushes the pressing block 8 into the limit port 4, the movement trajectory of the pressing block 8 is effectively limited, preventing excessive ejection. This makes the fixing process between the shielding shell 1 and the shielding cover body 2 more stable. (The text also mentions a slope, but this seems unrelated to the equipment malfunction and is likely a separate point.) With the setting of 11, when it is necessary to fix the shielding shell 1 and the shielding cover body 2, it is only necessary to align the shielding cover body 2 with the shielding shell 1 and attach it. The pressing block 8 will automatically slide into the limiting port 4 and pop out and snap, achieving rapid installation of the shielding cover body 2 and further improving the operation efficiency. Through the setting of the guide groove 12 and the guide block 13, the shielding cover body 2 and the shielding shell 1 can be automatically aligned during the attachment and installation process, so that the shielding cover body 2 will not be offset during the installation process, effectively ensuring the stability of the shielding function and the installation efficiency. Through the glass observation window 14 covered with a transparent metal film, the operator can easily observe the working status of the electronic components or circuits inside the shielding shell 1 and the shielding cover body 2, such as the on and off of the indicator lights and the operation of the components, without disassembling the shielding cover body 2, which facilitates the debugging, maintenance and troubleshooting of the equipment. By setting multiple heat dissipation fins 15 on the top of the shielding shell 1, the heat dissipation area of ​​the shielding shell 1 can be effectively increased, the heat dissipation efficiency can be improved, and the shielded electronic components or circuits can be better cooled, preventing performance or lifespan from being affected by overheating.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
