Description

Technical Field

[0001] This utility model relates to the technical field of shielding cover structure, and in particular to a shielding cover structure that is easy to disassemble. Background Technology

[0002] A shielding cover is a device used to protect electronic components and circuits from electromagnetic interference, physical damage, and environmental influences.

[0003] In the prior art, such as Chinese Publication No. CN218831166U, this utility model relates to an electromagnetic shielding cover, belonging to the technical field of electromagnetic shielding devices. It mainly addresses the problem that existing electromagnetic shielding covers, which use multiple isolation shielding plates within the main cover to isolate multiple electronic components, can only be distributed along one direction. That is, when the electronic components are not linearly distributed in one direction, it is impossible to install the corresponding shielding plate within the cover. The proposed technical solution is as follows: It includes a cover body, and an electromagnetic shielding plate is disposed inside the cover body. The electromagnetic shielding plate includes a first shielding plate and a second shielding plate. Both ends of the first shielding plate have first slots. This application, through the design of installing the electromagnetic shielding plate within the cover body, can separate various components for electromagnetic shielding; by dividing the electromagnetic shielding plate into a first shielding plate and a second shielding plate, it can be applied to different electronic component distribution methods, thus having a wider range of applications.

[0004] While the above-mentioned solutions have the advantages mentioned above, their disadvantages include the lack of a structure that allows workers to easily separate the shielding cover, which may reduce work efficiency and increase maintenance costs when installing or repairing electronic components inside the shielding cover; the lack of a convenient disassembly and assembly structure, which may damage the device's fasteners due to frequent disassembly and assembly, thereby affecting the fixing effect and sealing performance of the shielding cover; the lack of a multi-layer shielding structure to improve the device's shielding effect; and the lack of a structure to dampen and buffer the vibrations and shaking experienced by the shielding cover and shielding device, which may easily cause damage to electronic components and shielding devices and electromagnetic interference leakage, resulting in a reduction in the device's shielding effect. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for easy disassembly of the shielding cover. This utility model is designed to allow workers to easily separate the shielding cover, improving the work efficiency of workers when installing or repairing electronic components inside the shielding cover, reducing maintenance costs, and designing a convenient disassembly and assembly structure to avoid damage to the device fasteners caused by frequent disassembly and assembly, thereby improving the fixing effect and sealing performance of the shielding cover. A multi-layer shielding structure is set to improve the shielding effect of the device, and a structure is designed to dampen and buffer the vibration and shaking of the shielding cover and shielding device, avoiding damage to electronic components and shielding device and electromagnetic interference leakage, thereby improving the shielding effect of the device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a structure for easy disassembly of a shielding cover, comprising:

[0007] The enclosure, on the outer surface of which a motor is fixedly mounted, also includes:

[0008] Two first rotating shafts are rotatably connected to the outer surface of the housing. A first electro-hydraulic rod is fixedly mounted on the outer surface of each of the two first rotating shafts.

One end face of one of the second rotating shafts is fixedly connected to the output shaft of the motor. Two mounting plates are fixedly mounted on the outer surfaces of the two first electro-hydraulic rods and the two second electro-hydraulic rods. The first rotating shafts on both sides and the second electro-hydraulic rods on both sides drive the two mounting plates to separate from the top of the housing while maintaining a suitable distance from the top of the housing to avoid collision. When the motor is turned on, the motor output shaft drives the second rotating shafts, the second electro-hydraulic rods on both sides, and one mounting plate to rotate away from the top of the housing. Simultaneously, the motor drives the second gear and the first gear to reverse, thereby driving the first rotating shafts, the first electro-hydraulic rods on both sides, and the other mounting plate to rotate in the opposite direction away from the top of the housing.

By tightening or loosening the multiple fastening bolts and cooperating with the positioning pads, the mounting plates on both sides, the ferromagnetic material shielding plate, and the carbon-filled composite shielding plate can be easily fastened and disassembled with the first electro-hydraulic rods and the second electro-hydraulic rods.

[0011] Preferably, a ferromagnetic material shielding plate is fixedly embedded on the inner surface of one of the mounting plates, and a carbon-based filled composite shielding plate is fixedly embedded on the inner surface of the other mounting plate.

[0013] Preferably, each of the multiple shock-absorbing and damping outer surfaces is fixedly provided with a buffer spring, and each of the multiple buffer springs is fixedly connected to the bottom outer surface of the box body.

[0014] Preferably, two protective frames are fixedly installed on the outer surface of the base plate, and two guide rods are fixedly installed on the inner surface of each of the two protective frames, with the two protective frames supporting multiple guide rods.

[0015] Preferably, two limiting sliders are fixedly provided on the outer surface of the box, and the inner surfaces of the two limiting sliders are slidably connected to the outer surfaces of the multiple guide sliders respectively. The limiting sliders on both sides cooperate with the multiple guide sliders to protect and limit the box.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, the first rotating shafts on both sides and the second electric hydraulic rods on both sides drive the two mounting plates to separate from the top of the box and maintain an appropriate distance from the top of the box without collision. The motor output shaft drives the second rotating shaft, the second electric hydraulic rods on both sides and one mounting plate to rotate away from the top of the box. At the same time, the motor drives the second gear and the first gear to reverse, thereby driving the first rotating shaft, the first electric hydraulic rods on both sides and the other mounting plate to rotate in the opposite direction away from the top of the box. This facilitates the installation or maintenance of electronic components inside the box by the staff. By tightening or loosening multiple fastening bolts and cooperating with positioning pads, the mounting plates on both sides, the ferromagnetic material shielding plate and the carbon-filled composite shielding plate are easily fastened and disassembled with the first electric hydraulic rods and the second electric hydraulic rods. Multiple fixing screw holes are used to fix the mounting plates on both sides and the top of the box.

[0018] 2. In this utility model, when the box body is subjected to external impact and vibrates, multiple shock-absorbing damping extensions reduce the vibration and shaking of the box body. At the same time, multiple buffer springs undergo elastic deformation to buffer the vibration and shaking of the box body.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figures 1 to 4 As shown, this utility model provides a structure for convenient disassembly of a shielding cover, including a housing 1. A motor 14 is fixedly installed on the outer surface of the housing 1. Two first rotating shafts 15 are rotatably connected to the outer surface of the housing 1. A first electric hydraulic rod 17 is fixedly installed on the outer surface of each of the two first rotating shafts 15. A first gear 16 is fixedly sleeved on the outer surface of one of the first rotating shafts 15. Two second rotating shafts 18 are rotatably connected to the outer surface of the housing 1.

A second gear 20 is fixedly sleeved on the outer surface of one of the second rotating shafts 18. The second gear 20 meshes with the first gear 16. One end face of one of the second rotating shafts 18 is connected to... The output shaft of motor 14 is fixedly connected. Two mounting plates 2 are fixedly installed on the outer surfaces of the two first electro-hydraulic rods 17 and the two second electro-hydraulic rods 19. The first rotating shafts 15 on both sides and the second electro-hydraulic rods 19 on both sides drive the two mounting plates 2 to separate from the top of the box 1 and maintain an appropriate distance from collision. When motor 14 is turned on, the output shaft of motor 14 drives the second rotating shaft 18, the second electro-hydraulic rods 19 on both sides and one mounting plate 2 to rotate away from the top of the box 1. At the same time, motor 14 drives the second gear 20 and the first gear 16 to reverse, thereby driving the first rotating shaft 15, the first electro-hydraulic rods 17 on both sides and the other mounting plate 2 to rotate in the opposite direction and leave the top of the box 1.

[0028] Furthermore, such as Figures 1 to 4 As shown, multiple fixing screw holes 7 are provided on the outer surface of the top of the housing 1 and the outer surfaces of the two mounting plates 2. The multiple fixing screw holes 7 are respectively provided on the top of the housing 1 and the outer surfaces of the two mounting plates 2, and the mounting plates 2 on both sides and the top of the housing 1 are fastened and positioned through the multiple fixing screw holes 7.

[0029] Furthermore, such as Figures 1 to 4 As shown, the inner surfaces of the two first electro-hydraulic rods 17 and the two second electro-hydraulic rods 19 are each threaded with multiple fastening bolts 5. The multiple fastening bolts 5 are respectively threaded to the inner surfaces of the two mounting plates 2. The outer surfaces of the two mounting plates 2 are each movably connected with two positioning pads 6. By tightening or loosening the multiple fastening bolts 5 and cooperating with the positioning pads 6, the mounting plates 2 on both sides, the ferromagnetic material shielding plate 3 and the carbon-filled composite shielding plate 4 can be easily fastened and disassembled with the first electro-hydraulic rods 17 and the second electro-hydraulic rods 19.

[0030] Furthermore, such as Figures 1 to 4 As shown, a ferromagnetic material shielding plate 3 is fixedly embedded on the inner surface of one mounting plate 2, and a carbon-based filled composite shielding plate 4 is fixedly embedded on the inner surface of another mounting plate 2. The shielding effect of the device is improved by setting the ferromagnetic material shielding plate 3 and the carbon-based filled composite shielding plate 4.

[0031] Furthermore, such as Figures 1 to 4 As shown, multiple shock-absorbing dampers 10 are fixedly installed on the bottom outer surface of the box 1, and a base plate 12 is fixedly installed on the bottom outer surface of the multiple shock-absorbing dampers 10. The multiple shock-absorbing dampers 10 extend and retract to reduce the vibration and shaking of the box 1.

[0032] Furthermore, such as Figures 1 to 4 As shown, multiple shock-absorbing dampers 10 are fixedly provided with buffer springs 11 on their outer surfaces. Multiple buffer springs 11 are fixedly connected to the bottom outer surface of the housing 1.

The inner surfaces of the two limiting sliders 8 are slidably connected to the outer surfaces of multiple guide sliders 13 respectively. The limiting sliders 8 on both sides cooperate with the multiple guide sliders 13 to protect and limit the box 1.

[0035] Working principle: Opening the first rotating shaft 15 and the second electro-hydraulic rods 19 on both sides causes the two mounting plates 2 to separate from the top of the housing 1, maintaining a suitable distance to prevent collision. Turning on the motor 14 causes the output shaft of the motor 14 to rotate the second rotating shaft 18, the second electro-hydraulic rods 19 on both sides, and one mounting plate 2 away from the top of the housing 1. Simultaneously, the motor 14 drives the second gear 20 and the first gear 16 to reverse, thereby causing the first rotating shaft 15, the first electro-hydraulic rods 17 on both sides, and the other mounting plate 2 to rotate in the opposite direction away from the top of the housing 1. This facilitates the installation or maintenance of electrical components inside the housing 1. The sub-components, by tightening or loosening multiple fastening bolts 5 and cooperating with positioning pads 6, can easily fasten and disassemble the side mounting plates 2, ferromagnetic material shielding plates 3 and carbon-filled composite shielding plates 4 with the first electro-hydraulic rod 17 and the second electro-hydraulic rod 19. Multiple fixing screw holes 7 are used to securely fix the side mounting plates 2 and the top of the box 1. When the box 1 is subjected to external impact and vibrates, multiple shock-absorbing dampers 10 extend and retract to reduce the vibration and shaking of the box 1. At the same time, multiple buffer springs 11 undergo elastic deformation to buffer the vibration and shaking of the box 1. The side limit sliders 8, together with multiple guide sliders 13, protect and limit the box 1.
