[0001] This utility model relates to the field of electromagnetic shielding shell technology, specifically to an electromagnetic shielding shell assembly. Background Technology
[0002] Electronic products are now widely used in daily life. Some electronic devices need to be used in an electromagnetic shielding environment. Therefore, electromagnetic shielding shells are used to store and use them. Currently, most electromagnetic shielding shells are composed of a cover plate and a shell, and their connection is not reliable. Most of them are inserted by fitting rods together, which do not have stable stopping and are prone to loosening. Utility Model Content
[0003] In order to solve the above problems, the purpose of this utility model is to provide an electromagnetic shielding housing assembly.
[0004] To solve the above technical problems, the present invention adopts the following technical solution: an electromagnetic shielding shell assembly, including an outer shell and a cover plate, the cover plate being located above the outer shell, vertically arranged insert rods being fixedly provided at the four corners of the lower surface of the cover plate, the insert rods having through-cut fixing grooves, the four corners of the upper surface of the outer shell having slots corresponding to the insert rods, fixing plates being fixedly provided on both sides of the outer wall of the outer shell, rotating sleeves being rotatably provided at both ends of the fixing plates, positioning rods being threaded into the rotating sleeves, the positioning rods being inserted through the outer shell into the fixing grooves inside the insert rods, a drive gear being fixedly provided on the outer wall of the rotating sleeves, a toothed plate being slidably provided below the fixing plate and meshing with the drive gear, a slider being fixedly provided at the end of the toothed plate, and two sliders inside the fixing plate having a common fixed magnetic block at one end facing each other.
[0005] Preferably, a first stop is fixedly provided at the middle end of the fixed plate near each slider, a first spring is fixedly provided on the first stop, the end of the first spring away from the first stop is fixedly provided on the slider, and second stops are fixedly provided at both ends of the fixed plate.
[0006] Preferably, a limiting rod is fixedly provided on the slider, the first spring is sleeved above the limiting rod and the end of the limiting rod passes through the first stop block; the end of the toothed plate away from the first spring passes through the fixed plate, and a pressing block is provided at the end of the toothed plate outside the fixed plate.
[0007] Preferably, a mounting block is fixedly provided at the middle end of the outer wall of the fixing plate, the mounting block is in communication with the interior of the fixing plate, a top block is slidably provided inside the mounting block, one end of the two sliders is wedge-shaped, the end of the top block is wedge-shaped, a second spring is fixedly provided inside the mounting block and the end of the second spring is fixedly provided on the top block; a pull rod is fixedly provided at the end of the top block near the second spring, and the end of the pull rod passes through the mounting block.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, after the insertion rod is inserted into the slot to complete the initial connection, the positioning rod passes through the outer shell and is inserted into the fixing groove of the insertion rod to form a cross fixation. Compared with the traditional single insertion rod fitting, this greatly enhances the connection reliability between the cover plate and the outer shell and effectively prevents loosening problems caused by vibration, collision and other factors during use. 2. The operator only needs to insert the rod into the slot to complete the initial positioning, and then squeeze the pressing block to trigger the subsequent linkage mechanism, so that the positioning rod automatically inserts into the fixing groove. The whole process does not require complicated tools, the operation steps are simple, and the fixed installation of the shell and the cover plate can be completed quickly. At the same time, when disassembling, only the pull rod needs to be squeezed, and the slider is pushed by the top block to separate, which triggers the positioning rod to move in the opposite direction and get out of the fixing groove. Then, the cover plate can be pulled directly to complete the disassembly. This avoids the jamming or laborious problems that may occur during the disassembly of traditional structures, and takes into account both installation stability and operation convenience.

Detailed Implementation
[0016] 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.
[0017] Example: Figure 1-5 As shown, this utility model provides an electromagnetic shielding housing assembly, including an outer shell 1 and a cover plate 11. The outer shell 1 and the cover plate 11 are made of copper, aluminum, or stainless steel. These materials have high electrical conductivity and achieve shielding effect by reflecting electromagnetic waves, thus realizing the electromagnetic shielding housing structure of this invention. The cover plate 11 is located above the outer shell 1. Vertically arranged insert rods 12 are fixed at the four corners of the lower surface of the cover plate 11. Fixing grooves 13 are formed through the insert rods 12. Corresponding to the insert rods 12, fixing grooves 13 are formed at the four corners of the upper surface of the outer shell 1. The slot 18, the outer wall of the outer shell 1 is fixedly provided with fixing plates 14 on both sides, the two ends of the fixing plates 14 are rotatably provided with rotating sleeves 16, the rotating sleeves 16 are threaded with positioning rods 15, the positioning rods 15 pass through the outer shell 1 and are inserted into the fixing grooves 13 in the insert rods 12, the outer wall of the rotating sleeves 16 is fixedly provided with driving gears 2, the lower part of the fixing plates 14 is slidably provided with toothed plates 21 and the toothed plates 21 are meshed with the driving gears 2, the end of the toothed plates 21 is fixedly provided with sliders 22, and the two sliders 22 in the fixing plates 14 are fixedly provided with a magnetic block 44 at one end facing each other.
[0018] A first stop 3 is fixedly provided at the middle end of the fixed plate 14 near each slider 22. A first spring 31 is fixedly provided on the first stop 3. The end of the first spring 31 away from the first stop 3 is fixedly provided on the slider 22. Second stops 33 are fixedly provided at both ends of the fixed plate 14. The first spring 31 can quickly push the slider 22 to move, so that the slider 22 drives the toothed plate 21 to move out of the fixed plate 14. During this process, the toothed plate 21 will drive the drive gear 2 to rotate in the opposite direction, so as to achieve the purpose of quick disassembly.
[0019] A limiting rod 32 is fixedly provided on the slider 22. The first spring 31 is sleeved above the limiting rod 32 and the end of the limiting rod 32 passes through the first stop 3. The limiting rod 32 is mainly used to limit the first spring 31 to avoid excessive bending and reduced service life.
[0020] The toothed plate 21 has one end away from the first spring 31 that passes through the fixed plate 14. The toothed plate 21 is provided with a pressing block 23 at the end outside the fixed plate 14. The pressing block 23 can be easily squeezed by the staff to push the toothed plate 21 back into the fixed plate 14.
[0021] A mounting block 4 is fixedly provided at the middle end of the outer wall of the fixed plate 14. The mounting block 4 communicates with the interior of the fixed plate 14. A top block 41 is slidably provided inside the mounting block 4. The two sliders 22 are wedge-shaped at one end adjacent to each other. The end of the top block 41 is wedge-shaped. A second spring 42 is fixedly provided inside the mounting block 4, and the end of the second spring 42 is fixedly provided on the top block 41. The top block 41 is pushed to move by the pull rod 43, so that the two sliders 22 can be quickly separated. The toothed plate 21 fixedly provided at the end of the slider 22 drives the drive gear 2 to rotate in the opposite direction, thus completing the disengagement of the positioning rod 15 from the fixing groove 13.
[0022] A pull rod 43 is fixedly provided at one end of the top block 41 near the second spring 42. The end of the pull rod 43 passes through the mounting block 4. The pull rod 43 allows the staff to push the top block 41 to move, thereby causing the top block 41 to push the two sliders 22 to separate and complete the disassembly operation.
[0023] Working principle: In use, the outer shell 1 of the electromagnetic shielding housing is first placed inside the outer shell 1. Then, the operator inserts the plug 12 at the bottom of the cover plate 11 into the slot 18 on the outer shell 1, completing the initial connection between the cover plate 11 and the outer shell 1. Next, the operator can squeeze the pressing block 23 extending out of the fixing plate 14. The pressing block 23 pushes the toothed plate 21 into the fixing plate 14, causing the toothed plate 21 to push the slider 22 to move until the magnetic blocks 44 at the ends of the two sliders 22 attract each other. During this process, the toothed plate 21 will... The drive gear 2 drives the rotation, and the rotating drive gear 2 will drive the fixed rotating sleeve 16 to rotate. The positioning rod 15, which is threaded into the rotating sleeve 16, will gradually pass through the outer shell 1 and be inserted into the fixing groove 13 in the insertion rod 12. At this time, the cover plate 11 and the top of the outer shell 1 will be finally fixed. Through the above operation, the outer shell 1 and the cover plate 11 can be fixed and installed quickly, and the positioning rod 15 is inserted into the fixing groove 13 for a second layer of fixation. Through the cross-fixing method, the outer shell 1 and the cover plate 11 of the electromagnetic shielding shell are stably fixed. When the staff disassembles the cover plate 11 from the outer shell 1, they can directly squeeze the pull rod 43 on the side wall of the outer shell 1, causing the pull rod 43 to push the top block 41 to move and insert between the two sliders 22. At this time, the top block 41 will push the two sliders 22 to separate. During this process, the first spring 31 will push the slider 22 towards the end of the fixing plate 14. At this time, the toothed plate 21 fixed at the end of the slider 22 will drive the drive gear 2 to rotate in the opposite direction, thereby driving the rotating sleeve 16 to rotate the positioning rod 15 so that it gradually disengages from the fixing groove 13 on the insertion rod 12. The staff can then pull the outer shell 1 along the gap between the outer shell 1 and the cover plate 11 to make the outer shell 1 detach from the cover plate 11. While ensuring stable installation, it also has a quick disassembly mode, increasing the practicality of the electromagnetic shielding shell assembly.
