Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, specifically to an electromagnetic shielding cabinet. Background Technology

[0002] An electromagnetic shielding cabinet is a specially designed enclosed cabinet used to prevent electromagnetic interference and protect equipment and personnel from electromagnetic radiation. It is commonly used in various electronic devices, communication equipment, medical equipment, and other applications, effectively shielding against external electromagnetic interference (EMI) and internal electromagnetic leakage (EMC), ensuring the equipment operates normally in an interference-free environment.

[0003] Traditional electromagnetic shielding cabinets mostly use a single layer of conductive gasket or metal spring to achieve the seal between the cabinet door and the cabinet body. Although they have basic electromagnetic shielding capabilities, they are prone to structural deformation during long-term use, which can lead to loose sealing and potential electromagnetic leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electromagnetic shielding cabinet with advantages such as a linked double-layer sealing mechanism that improves the reliability and service life of the sealing structure. It solves the problem that the current method of using a single-sided conductive gasket or metal spring between the cabinet door and the cabinet body can only achieve basic electromagnetic shielding capabilities, resulting in poor sealing and electromagnetic interference resistance between the cabinet door and the cabinet body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic shielding cabinet, including a cabinet, a top cover, a cabinet door, and a sealing element. The top cover is fixed on the cabinet, and an exhaust duct is provided on the side of the top cover. The temperature generated inside the cabinet is specially treated by the top cover, so as to provide the necessary heat dissipation channel for the equipment inside the cabinet while ensuring the electromagnetic shielding effectiveness.

[0006] The cabinet has a fixed frame inside, and a cabinet door is rotatably connected to the front of the cabinet. The cabinet door is movably connected inside the frame and matches the door frame on the front of the cabinet. When the cabinet door is closed to the door frame, the cabinet door is inside the frame.

[0007] A sealing element is movably connected inside the frame. The sealing element consists of a first sealing frame and a second sealing frame. The back of the first sealing frame and the second sealing frame are fixed. The first sealing frame is used to close with the cabinet door, and the second sealing frame is used to close with the frame, so as to achieve double sealing and improve the sealing performance between the cabinet and the cabinet door.

[0008] A side panel is fixed to the side of the cabinet door. The first sealing frame engages with the side panel at a set position, while the second sealing frame is attached to the frame at a set position. The first sealing frame has a double-layer design. When the cabinet door and the cabinet are closed, the first and second sealing frames are displaced, and the side panel engages in the gap between the first sealing frames to improve the sealing strength. At the same time, the second sealing frame is attached to the inside of the frame to further improve the sealing strength.

[0009] When using this electromagnetic shielding cabinet, the required anti-interference equipment is installed inside the cabinet, and then the cabinet door is closed. When the cabinet door is closed, the rotational force generated by the rotation of the cabinet door drives the transmission gear to rotate. Under the action of the transmission gear meshing with the transmission plate, the sealing element is moved forward as a whole, so that the side plate engages with the first sealing frame, and the second sealing frame fits against the frame, achieving a double seal at the gap between the cabinet door and the cabinet. At this time, the tension spring tightens, and the locking kit locks the cabinet door and the cabinet.

[0010] As a further improvement to the above solution, casters and feet are installed at the bottom of the cabinet.

[0011] With the above technical solution, casters and retractable legs are installed at the four corners of the bottom of the cabinet. After the cabinet is moved to the appropriate position by the casters, the bottom of the legs are attached to the ground to fix the position of the cabinet.

[0012] As a further improvement to the above solution, the cabinet and cabinet door are equipped with locking kits, and the cabinet door is also rotatably connected with an adjustment plate.

[0013] Through the above technical solution, the locking kit consists of a locking plate and a lock body. The locking plate is fixed to one side of the cabinet, while the lock body is fixed to the cabinet door. When the cabinet door is closed, the lock cylinder of the lock body is inserted into the locking plate to achieve the locking operation after the cabinet door is closed.

[0014] As a further improvement to the above solution, a rotating block is fixed on one side of the cabinet door, and the rotating block is rotatably connected to the inside of the cabinet.

[0015] With the above technical solution, rotating blocks are provided at the top and bottom of one side of the cabinet door. The two rotating blocks are respectively rotatably connected to the corresponding positions at the top and bottom of one side of the cabinet, so that the cabinet door rotates around the rotating blocks as the axis, realizing the opening and closing operation between the cabinet and the cabinet.

[0016] As a further improvement to the above solution, a clamping plate is fixed on one side of the cabinet door, and a transmission gear is fixed inside the clamping plate. At the same time, a transmission plate is provided on one side of the first sealing frame, and the transmission gear meshes with the transmission plate.

[0017] With the above technical solution, clamps are fixed at the top and bottom of one side of the cabinet door. The two clamps are located between two rotating blocks, and the clamps and rotating blocks are vertically aligned. At the same time, the transmission gears inside the clamps mesh with the corresponding transmission plates on the side of the first sealing frame. Thus, when the cabinet door is opened outward, the sealing element moves into the cabinet as a whole, and when the cabinet door is closed inward, the sealing element moves outward, thereby achieving the closing and unclosing operation of double-layer protection.

[0018] As a further improvement to the above solution, a stabilizing groove is provided on the side of the transmission plate, and a stabilizing button is slidably connected in the stabilizing groove. One end of the stabilizing button is fixed in the corresponding position inside the cabinet.

[0019] With the above technical solution, the stabilizing slide button is fixed in the corresponding position inside the cabinet. Under the action of the meshing transmission force of the transmission gear and the transmission plate, the seal is displaced as a whole. At this time, the stabilizing slide groove slides on the side of the stabilizing slide button, thereby limiting the displacement distance of the seal and avoiding excessive movement.

[0020] As a further improvement to the above solution, the first sealing frame is composed of an inner frame plate and an outer frame plate. A first electromagnetic shielding strip is fixed on the opposite side of the inner frame plate and the outer frame plate and is attached to the side of the side plate.

[0021] Through the above technical solution, the inner frame plate and the outer frame plate are attached to the side plate, thereby pressing the first electromagnetic shielding strip tightly to the inner and outer sides of the side plate, thereby enhancing the sealing and anti-interference strength of the door gap when the cabinet door is closed, and achieving the first layer of sealing.

[0022] As a further improvement to the above solution, a second electromagnetic shielding strip is fixed on the second sealing frame, and the second electromagnetic shielding strip is attached to the frame.

[0023] Through the above technical solution, when the cabinet door and the cabinet are closed, the displacement of the sealing element causes the second sealing frame to press the second electromagnetic shielding strip tightly onto the frame, thus achieving a second layer of sealing.

[0024] As a further improvement to the above solution, a sleeve is fixed to the side of the second sealing frame, and a stabilizing rod is movably connected inside the sleeve, with one end of the stabilizing rod fixed to the frame.

[0025] With the above technical solution, sleeves are fixed at the top and bottom of both sides of the second sealing frame. The stabilizing rod inside the sleeve is fixed at the corresponding position on the back of the frame. When the sealing component is displaced as a whole, the sleeve slides on the side of the stabilizing rod, thereby improving the stability of the sealing component's displacement.

[0026] As a further improvement to the above solution, a tension spring is movably sleeved on the stabilizing rod, with both ends of the tension spring fitting between the sleeve and the frame.

[0027] Through the above technical solution, when the cabinet door and the cabinet are opened, the directional force generated, and under the push of the tension spring, causes the seal to return to its initial position.

[0028] As a further improvement to the above solution, a limit button is fixed to one end of the stabilizing rod, and the limit button is attached to the sleeve.

[0029] Through the above technical solution, the limit button is used to limit the distance of the sleeve movement and prevent the sleeve from detaching from the stabilizing rod.

[0030] Compared with the prior art, this utility model provides an electromagnetic shielding cabinet, which has the following beneficial effects:

[0031] 1. When the cabinet door is closed, the first sealing frame engages with the side panel, causing the first electromagnetic shielding strip on the inside to be tightly attached to both the inner and outer sides of the side panel. This enhances the protection against electromagnetic interference compared to traditional cabinets. Simultaneously, the second sealing frame is attached to the frame, ensuring the second electromagnetic shielding strip is tightly attached to the frame, thus achieving double-layer anti-interference protection and significantly improving the electromagnetic shielding capability of the cabinet.

[0032] 2. When the cabinet door is opened and closed, the rotational force generated drives the transmission gear to rotate. The force of the transmission gear meshing with the transmission plate causes the overall displacement of the sealing components to change, thereby realizing dual linkage control and effectively improving the practicality of the device.

Detailed Implementation

[0044] 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

[0045] Please see Figure 1-6 As shown, the electromagnetic shielding cabinet proposed in this embodiment includes a cabinet 1, a top cover 2, a cabinet door 3, and a sealing element 4. The top cover 2 is fixed on the cabinet 1, and an exhaust duct 201 is provided on the side of the top cover 2. The temperature generated inside the cabinet 1 is specially treated by the top cover 2, so as to provide the necessary heat dissipation channel for the equipment inside the cabinet while ensuring the electromagnetic shielding performance.

[0046] The cabinet 1 is fixed with a frame 103, and the front side of the cabinet 1 is rotatably connected with a cabinet door 3. The cabinet door 3 is movably connected inside the frame 103. The cabinet door 3 matches the door frame on the front side of the cabinet 1. When the cabinet door 3 is closed with the door frame, the cabinet door 3 is inside the frame 103.

[0047] A sealing element 4 is movably connected inside the frame 103. The sealing element 4 consists of a first sealing frame 404 and a second sealing frame 405. The back of the first sealing frame 404 and the second sealing frame 405 are fixed. The first sealing frame 404 is used to close with the cabinet door 3, and the second sealing frame 405 is used to close with the frame 103, so as to achieve double sealing and improve the sealing performance between the cabinet 1 and the cabinet door 3.

[0048] A side panel 306 is fixed to the side of the cabinet door 3. A first sealing frame 404 engages with the side panel 306 at a set position, while a second sealing frame 405 is attached to the frame 103 at a set position. The first sealing frame 404 has a double-layer design. When the cabinet door 3 is closed with the cabinet 1, the first sealing frame 404 and the second sealing frame 405 are displaced, and the side panel 306 engages in the gap between the first sealing frames 404 to improve the sealing strength. At the same time, the second sealing frame 405 is attached to the inner side of the frame 103 to further improve the sealing strength.

[0049] The working principle of the electromagnetic shielding cabinet proposed in this embodiment is as follows: When in use, the required anti-interference equipment is installed in the cabinet 1, and then the cabinet door 3 is closed to the cabinet 1. When closed, the rotational force generated by the rotation of the cabinet door 3 drives the transmission gear 305 to rotate. Under the action of the meshing force between the transmission gear 305 and the transmission plate 401, the sealing element 4 is moved forward as a whole, so that the side plate 306 is engaged with the first sealing frame 404, and the second sealing frame 405 is attached to the frame 103, so as to achieve double sealing at the gap between the cabinet door 3 and the cabinet 1. At this time, the tension spring 408 is tightened, and then the locking kit 301 is used to lock the cabinet door 3 and the cabinet 1.

[0050] Furthermore, the bottom of the cabinet 1 is equipped with casters 101 and support legs 102.

[0051] More specifically, casters 101 and retractable legs 102 are installed at the four corners of the bottom of the cabinet 1. After the cabinet 1 is moved to the appropriate position by the casters 101, the bottom of the legs 102 are attached to the ground to fix the position of the cabinet 1.

[0052] Furthermore, a locking kit 301 is installed on the cabinet 1 and the cabinet door 3, and an adjusting plate 302 is rotatably connected to the cabinet door 3.

[0053] More specifically, the latch kit 301 consists of a latch plate and a lock body. The latch plate is fixed to one side of the cabinet 1, while the lock body is fixed to the cabinet door 3. When the cabinet door 3 is closed to the cabinet 1, the lock cylinder of the lock body is inserted into the latch plate to achieve the locking operation after the cabinet door 3 is closed to the cabinet 1.

[0054] Furthermore, a rotating block 303 is fixed on one side of the cabinet door 3, and the rotating block 303 is rotatably connected to the inside of the cabinet 1.

[0055] More specifically, rotating blocks 303 are provided at the top and bottom of one side of the cabinet door 3. The two rotating blocks 303 are respectively rotatably connected to the corresponding positions at the top and bottom of one side of the cabinet 1, so that the cabinet door 3 rotates around the rotating block 303 as the axis, realizing the opening and closing operation between the cabinet door 3 and the cabinet 1. Example

[0056] Please see Figures 4-6 As shown, the electromagnetic shielding cabinet proposed in this embodiment, based on the first embodiment, further includes a clamping plate 304 fixed on one side of the cabinet door 3, a transmission gear 305 fixed inside the clamping plate 304, and a transmission plate 401 provided on one side of the first sealing frame 404, with the transmission gear 305 meshing with the transmission plate 401.

[0057] More specifically, clamping plates 304 are fixed at the top and bottom of one side of the cabinet door 3. The two clamping plates 304 are located between the two rotating blocks 303. At the same time, the clamping plates 304 and the rotating blocks 303 are vertically aligned. Meanwhile, the transmission gear 305 inside the clamping plate 304 meshes with the corresponding transmission plate 401 on the side of the first sealing frame 404. Thus, when the cabinet door 3 is opened outward, the sealing element 4 moves into the cabinet 1 as a whole, and when the cabinet door 3 is closed inward, the sealing element 4 moves outward from the cabinet 1 as a whole, thereby realizing the closing and unclosing operation of double-layer protection.

[0058] Furthermore, a stabilizing groove 402 is provided on the side of the transmission plate 401, and a stabilizing button 403 is slidably connected in the stabilizing groove 402. One end of the stabilizing button 403 is fixed in the corresponding position inside the cabinet 1.

[0059] More specifically, the stabilizing slider 403 is fixed at the corresponding position inside the cabinet 1. Under the action of the meshing transmission force of the transmission gear 305 and the transmission plate 401, the seal 4 is displaced as a whole. At this time, the stabilizing groove 402 slides on the side of the stabilizing slider 403, thereby limiting the displacement distance of the seal 4 and avoiding excessive movement.

[0060] Furthermore, the first sealing frame 404 is composed of an inner frame plate 4041 and an outer frame plate 4042. A first electromagnetic shielding strip 4043 is fixed on the opposite surfaces of the inner frame plate 4041 and the outer frame plate 4042 and is attached to the side of the side plate 306.

[0061] More specifically, the inner frame plate 4041 and the outer frame plate 4042 are attached to the side plate 306 to press the first electromagnetic shielding strip 4043 tightly against the inner and outer sides of the side plate 306, thereby enhancing the sealing and anti-interference strength of the door gap when the cabinet door 3 is closed with the cabinet 1, and achieving the first layer of sealing.

[0062] Furthermore, a second electromagnetic shielding strip 4051 is fixed on the second sealing frame 405, and the second electromagnetic shielding strip 4051 is attached to the frame 103.

[0063] More specifically, when the cabinet door 3 and the cabinet 1 are closed, the displacement of the sealing element 4 causes the second sealing frame 405 to press the second electromagnetic shielding strip 4051 onto the frame 103, thus achieving a second layer of sealing.

[0064] Furthermore, a sleeve 406 is fixed to the side of the second sealing frame 405, and a stabilizing rod 407 is movably sleeved inside the sleeve 406. One end of the stabilizing rod 407 is fixed to the frame 103.

[0065] More specifically, sleeves 406 are fixed at the top and bottom of both sides of the second sealing frame 405. The stabilizing rod 407 inside the sleeve 406 is fixed at the corresponding position on the back of the frame 103. When the seal 4 as a whole is displaced, the sleeve 406 slides on the side of the stabilizing rod 407, thereby improving the stability of the displacement of the seal 4.

[0066] Furthermore, a tension spring 408 is movably sleeved on the stabilizing rod 407, with both ends of the tension spring 408 fitting between the sleeve 406 and the frame 103.

[0067] More specifically, when the cabinet door 3 and the cabinet 1 are opened, the resulting directional force, and the push of the tension spring 408, causes the seal 4 to return to its initial position.

[0068] Furthermore, a limit button 409 is fixed to one end of the stabilizing rod 407, and the limit button 409 is attached to the sleeve 406.

[0069] More specifically, the limit button 409 is used to limit the distance the sleeve 406 moves, preventing the sleeve 406 from disengaging from the stabilizing rod 407.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
