Description

Technical Field

[0001] This utility model belongs to the field of shielding cover technology, specifically relating to a quick-disassembly shielding cover. Background Technology

[0002] A shielding cover is a metal enclosure used in electronic devices. It is usually made of materials with good conductivity and electromagnetic shielding properties, such as copper, aluminum, iron and their alloys. It is mainly used to isolate electronic components or circuit modules from the external electromagnetic environment. By reflecting, absorbing or guiding electromagnetic waves, it prevents external electromagnetic waves from entering the internal circuits, and also prevents electromagnetic waves generated by the internal circuits from leaking into the external space, thereby reducing electromagnetic interference and improving the electromagnetic compatibility of electronic devices.

[0003] However, in actual equipment maintenance scenarios, when it comes to inspecting the internal circuitry of the shielding cover, the shielding cover needs to be disassembled. Disassembling the shielding cover is not convenient and can greatly hinder the maintenance work. Maintenance personnel have to spend a lot of time just on the basic operation of removing the shielding cover. They have to carefully try various tools and methods, or use special disassembly tools, or rely on their rich experience to constantly adjust the angle and force of application. However, the whole process is extremely cumbersome and greatly slows down the maintenance progress.

[0004] To address the aforementioned issues, this application proposes a quick-release shielding cover. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a quick-disassembly shielding cover, which enables the shielding cover to be disassembled quickly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-disassembly shielding cover, comprising a shielding cover, a base frame snapped onto the outer surface of the shielding cover, two sets of slotted shells fixedly connected to the inner wall of the base frame, a limiting frame slidably connected inside each slotted shell, the outer surface of each limiting frame contacting the inner wall of the shielding cover, a telescopic spring fixedly connected to the inner wall of each slotted shell, one end of each set of telescopic springs approaching each other contacting the side of each set of limiting frames away from each other, a pull rod fixedly connected to the side of each set of limiting frames away from each other, and the outer surface of each pull rod slidably connected to the inner wall of the slotted shell.

[0007] As a preferred embodiment of this utility model, a dustproof frame is fixedly connected to the outer surface of the shielding cover, and the bottom surface of the dustproof frame is in contact with the upper surface of the base frame.

[0008] As a preferred embodiment of this utility model, the shielding cover is fixedly connected to both the front and back sides with connecting plates, and the two connecting plates are fixedly connected to each other on the side that is far apart from each other with an assist plate.

[0009] As a preferred embodiment of this utility model, two connecting frames are fixedly connected to the left and right sides of the base frame, and each connecting frame has a fixing pin inserted inside.

[0010] As a preferred technical solution of this utility model, a reinforcing frame is fixedly connected to the outer surface of each of the slot shells, and the side of each group of reinforcing frames that is close to each other is fixedly connected to the front and back of the base frame respectively.

[0011] As a preferred embodiment of this utility model, a viewing plate is snapped onto the upper surface of each of the slot shells, a fixing frame is fixedly connected to the outer surface of each of the viewing plates, and the bottom surface of each fixing frame is fixedly connected to the upper surface of the slot shell.

[0012] As a preferred technical solution of this utility model, each set of pull rods has a connecting ring fixedly connected to one end that is far apart from each other, and each set of connecting rings has a handle fixedly connected to one side that is far apart from each other.

[0013] As a preferred technical solution of this utility model, a fixing plate is fixedly connected to the outer surface of each of the telescopic springs, and the side of each group of fixing plates that is close to each other is fixedly connected to the side of each group of limiting frames that is far from each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a shielding cover in conjunction with a base frame, it can be assembled and used for shielding. At the same time, by utilizing the shape of the shielding cover and the base frame, the shielding cover can be placed inside the base frame. Through the elastic force of the telescopic spring, the limiting frame can be pushed to slide closer to each other in the slot shell. Through the sliding of the limiting frame, the shielding cover can be limited inside the base frame, thereby enabling the shielding cover and the base frame to be assembled and used stably. Then, by using a pull rod, the limiting frame can be pulled, and by the movement of the limiting frames away from each other, the shielding cover can be released from the limitation, thereby enabling the shielding cover to be disassembled from the base frame. Furthermore, it enables the shielding cover and the base frame to be conveniently disassembled and assembled for use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a quick-disassembly shielding cover, comprising a shielding cover 1, a base frame 2 snapped onto the outer surface of the shielding cover 1, two sets of slot shells 3 fixedly connected to the inner wall of the base frame 2, a limit frame 14 slidably connected inside each slot shell 3, the outer surface of each limit frame 14 contacting the inner wall of the shielding cover 1, a telescopic spring 16 fixedly connected to the inner wall of each slot shell 3, the end of each set of telescopic springs 16 that is close to each other contacting the side of each set of limit frames 14 that is far away from each other, a pull rod 17 fixedly connected to the side of each set of limit frames 14 that is far away from each other, and the outer surface of each pull rod 17 slidably connected to the inner wall of the slot shell 3;

[0024] In this embodiment, the shielding cover 1 and the base frame 2 are made of alloy materials. By alloying different metal elements, the advantages of multiple metals can be combined to obtain better performance. At the same time, the right side of the shielding cover 1 is provided with a ventilation port to allow air circulation, remove heat, and maintain the normal operating temperature of the equipment. Furthermore, by matching the shape of the bottom of the shielding cover 1 with the shape of the limiting frame 14, the limiting frame 14 can slide away from each other within the groove shell 3 when the shielding cover 1 squeezes the limiting frame 14. When the shielding cover 1 reaches the bottom of the base frame 2, the limiting frame 14 can be pushed into the interior of the shielding cover 1 by the elastic force of the telescopic spring 16, thus limiting the shielding cover 1.

[0025] Specifically, a dustproof frame 7 is fixedly connected to the outer surface of the shielding cover 1. The bottom surface of the dustproof frame 7 is in contact with the upper surface of the base frame 2. In this embodiment, the dustproof frame 7 can block the connection between the shielding cover 1 and the base frame 2, thereby reducing the amount of dust entering the interior of the base frame 2.

[0026] Specifically, the front and back of the shielding cover 1 are fixedly connected to connecting plates 4, and the two connecting plates 4 are fixedly connected to each other on the side that is far apart. In this embodiment, the connecting plates 4 can fix the auxiliary plates 5 to the shielding cover 1, and the auxiliary plates 5 can be used to move the shielding cover 1 easily.

[0027] Specifically, two connecting frames 8 are fixedly connected to the left and right sides of the base frame 2. Each connecting frame 8 has a fixing pin 6 inside. In this embodiment, the connecting frame 8 can be fixed to the base frame 2, and the fixing pin 6 can be used to fix the connecting frame 8, thereby enabling the base frame 2 to be used in a fixed manner.

[0028] Specifically, each outer surface of the slot shell 3 is fixedly connected with a reinforcing frame 9. The side of each set of reinforcing frames 9 that is close to each other is fixedly connected to the front and back of the base frame 2 respectively. In this embodiment, the reinforcing frame 9 can reinforce the slot shell 3 to the base frame 2 and make the slot shell 3 sturdy.

[0029] Specifically, a viewing plate 10 is snapped onto the upper surface of each tank shell 3, and a fixing frame 11 is fixedly connected to the outer surface of each viewing plate 10. The bottom surface of each fixing frame 11 is fixedly connected to the upper surface of the tank shell 3. In this embodiment, the viewing plate 10 can be fixed to the tank shell 3 through the fixing frame 11, and the interior of the tank shell 3 can be easily observed using the viewing plate 10.

[0030] Specifically, each set of pull rods 17 has a connecting ring 12 fixedly connected to one end of each set of pull rods 17 that is far apart from each other, and a handle 13 fixedly connected to one side of each set of connecting rings 12 that is far apart from each other. In this embodiment, the handle 13 can be fixed to the pull rod 17 through the connecting ring 12, and the pull rod 17 can be moved easily through the handle 13.

[0031] Specifically, each telescopic spring 16 has a fixed plate 15 fixedly connected to its outer surface. The side of each fixed plate 15 that is close to each other is fixedly connected to the side of each set of limiting frames 14 that is far away from each other. In this embodiment, the fixed plate 15 can fix the telescopic spring 16 to the limiting frame 14, thereby enabling the telescopic spring 16 to push the limiting frame 14 to move.

[0032] The working principle and usage process of this utility model are as follows: First, using the connecting frame 8 and the fixing pin 6, the base frame 2 is fixed to a suitable position, and the corresponding equipment is fixed onto the base frame 2 for use. Simultaneously, using the connecting plate 4 and the assist plate 5, the shielding cover 1 is pushed into the base frame 2. As the shielding cover 1 moves, it compresses the limiting frame 14, causing each set of limiting frames 14 to slide away from each other within the slot shell 3. The sliding of the limiting frames 14 compresses the telescopic spring 16. When the shielding cover 1 reaches the bottom of the base frame 2, the elastic force of the telescopic spring 16 pushes each set of limiting frames 14 closer together, simultaneously moving the limiting frames 14 into the interior of the shielding cover 1 and locking the shielding cover 1 into the base frame 2. This allows the shielding cover 1 to work with the base frame 2 for shielding. When it is necessary to disassemble the shielding cover 1 and the base frame 2, the handle 13 and the connecting ring 12 are used to move each set of pull rods 17 away from each other. The movement of the pull rods 17 causes each set of limit frames 14 to slide away from each other within the slot shell 3. At the same time, the limit frames 14 release their contact with the shielding cover 1. Then, the connecting plate 4 and the assist plate 5 are used to move the shielding cover 1 out of the base frame 2, thereby disassembling the shielding cover 1 and the base frame 2. After the shielding cover 1 moves out of the base frame 2, the force applied to the pull rods 17 is released, and the elastic force of the telescopic spring 16 causes the limit frames 14 to return to their original positions, further enabling the shielding cover 1 to be easily disassembled and used.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
