Description

Technical Field

[0001] This utility model relates to the field of communication chassis technology, and in particular to an electromagnetic shielding structure for a communication chassis with anti-interference function. Background Technology

[0002] Currently, communication enclosures often utilize their structural characteristics to achieve electromagnetic shielding, thereby reducing electromagnetic interference. In structural selection, materials with good conductivity or magnetic permeability are preferred, with metals like copper, aluminum, and steel being common choices. Copper has excellent conductivity, making it suitable for high-performance shielding applications; aluminum is lightweight, low-cost, and has good conductivity, making it widely used in various enclosures; steel, possessing both conductivity and magnetic permeability, offers outstanding shielding against low-frequency magnetic fields. For example, Chinese patent CN216873544U discloses an electromagnetic interference-resistant communication enclosure. During equipment operation, the positioning plate adjustment requires the removal and installation of a pair of locking nuts to move and adjust the device. During operation, the locking nuts must first be loosened to release the limiting force on the positioning plate, and after the positioning plate is adjusted, the locking nuts must be tightened again to complete the fixation. This repetitive nut removal and installation is considered "low-value repetitive labor." While individual steps are short-lived, the cumulative effect significantly slows down the overall operation process. For instance, during equipment maintenance, repeated nut removal and installation directly extends downtime. There are also operational efficiency issues in the use of the drive lever. When using the drive lever, one hand needs to push the lever to the appropriate position while the other hand simultaneously rotates the limit stop to fix the drive lever in place. This requires a high degree of coordination and rhythm; if one hand's movement falters (e.g., the lever is obstructed or the stop is not rotated smoothly), the other hand must pause, further reducing operational efficiency. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an electromagnetic shielding structure for a communication chassis with anti-interference function.

[0004] The technical solution of this utility model is as follows: an electromagnetic shielding structure for a communication chassis with anti-interference function, including a communication chassis, a drive rod on the communication chassis, and a positioning plate and a support plate that are positioned opposite each other inside the communication chassis. It also includes: a spring-loaded mechanism mounted on the support plate to push the positioning plate towards the drive rod; a locking mechanism located on the communication chassis that drives the positioning plate towards the support plate; and a reset mechanism mounted on the communication chassis to drive the positioning plate and the support plate into the communication chassis. The communication chassis also has a latching mechanism for locking the reset mechanism.

[0005] Optionally, the rebound mechanism includes a plurality of second support columns fixedly connected to the bearing plate, each of the second support columns being movably fitted with a second return spring, the end of each second support column away from the bearing plate being fixedly connected to a connecting plate, and the end of each second support column near the connecting plate being movably connected through a positioning plate.

[0006] Optionally, the locking mechanism includes a disc, the outer wall of which is fixedly connected to the end of the connecting plate away from the second support column, and a bolt with its end abutting against the middle of the positioning plate is spirally passed through the middle of the disc.

[0007] Optionally, the reset mechanism includes a pair of limiting slide grooves on the communication box corresponding to the ends of the drive rods. Each end of the limiting slide groove is provided with a first convex plate and a second convex plate fixedly connected to the communication box. A first support column is fixedly connected to the middle of each of the first and second convex plates. A first reset spring is movably sleeved on the first support column. The ends of the first support column away from the second convex plate movably pass through the ends of the drive rods. The ends of the first reset springs away from the second convex plate are also fixedly connected to the corresponding ends of the drive rods. Each end of the drive rod is fixedly connected with a connecting rod that movably passes through the limiting slide grooves. The ends of the connecting rods away from the drive rods are fixedly connected to a positioning plate.

[0008] Optionally, the latching mechanism includes a pair of rotating supports fixedly connected to the communication box. A tilting latch rod is fixedly connected to the middle of the rotating supports. The tilting latch rod is rotated toward the communication box after being pushed by the driving pull rod. A pressing rod is fixedly connected to the middle of the tilting latch rod. A third return spring is fixedly connected to the end of the pressing rod away from the tilting latch rod. The third return spring is used to cause the pressing rod to drive the tilting latch rod to latch the driving pull rod.

[0009] Optionally, the upper surface of the end of the pressing rod away from the tilting lever is provided with a pressing mark.

[0010] Optionally, the open end of the communication box is connected to an inspection door via a hinge.

[0011] Optionally, the first convex plate, the second convex plate, the first support column, the first reset spring, the connecting rod, and the limiting slide are all symmetrically arranged with the inclined locking rod as the center.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention optimizes the operation process of the communication box by utilizing a combination of a spring-loaded mechanism, a locking mechanism, a reset mechanism, and a latching mechanism. When adjusting the distance between the positioning plate and the support plate, there is no need to remove the nuts; simply rotating the bolt on the disc allows for quick and easy adjustment of the distance by varying the force exerted by the bolt end against the center of the positioning plate. This simple and efficient operation is achieved. When the positioning plate and support plate need to be removed from the communication box, the drive lever does not require manual operation. After being pushed to the appropriate position, the tilting lever automatically engages with the drive lever under the action of the third reset spring, preventing delays caused by manual operation and significantly reducing equipment downtime for maintenance, thus greatly improving operational convenience.

[0025] Example

[0026] like Figures 1 to 4As shown, the electromagnetic shielding structure of the communication enclosure with anti-interference function proposed in this utility model includes a communication enclosure 1. The open end of the communication enclosure 1 is connected to an inspection door 2 via a hinge. Opening the inspection door 2 facilitates operation of components such as the positioning plate 13 and the support plate 15 inside the enclosure; closing it ensures the sealing and shielding effect of the communication enclosure 1. The communication enclosure 1 is equipped with a drive rod 7. Pushing the drive rod 7 moves the positioning plate 13, which, in conjunction with a snap-fit ​​mechanism, achieves positioning without the need for two hands, improving adjustment efficiency. Inside the communication enclosure 1, there are also vertically opposite positioning plates 13 and support plates 15. The positioning plate 13 can slide along the second support column 10, cooperating with the support plate 15 to fix the equipment inside the communication enclosure 1, ensuring equipment stability and maintaining the shielding effect. The support plate 15 and the positioning plate 13 cooperate to clamp the equipment, ensuring the equipment's stable position inside the enclosure.

[0027] Among them, such as Figures 3 to 4 As shown, a spring-loaded mechanism is installed on the support plate 15 to push the positioning plate 13 towards the drive rod 7. The spring-loaded mechanism includes multiple second support columns 10 fixedly connected to the support plate 15, which provide sliding support for the positioning plate 13. Each second support column 10 is movably fitted with a second return spring 12. The release force of the second return spring 12 can push the positioning plate 13 back towards the drive rod 7. A connecting plate 11 is fixedly connected to the end of each second support column 10 away from the support plate 15. The connecting plate 11 allows the force of the bolt 8 to be transmitted to the positioning plate 13 through the disc 9 and the connecting plate 11. The end of each second support column 10 near the connecting plate 11 movably passes through the positioning plate 13. The positioning plate 13 and the support plate 15 cooperate to fix the equipment inside the communication box 1, ensuring equipment stability and maintaining the shielding effect.

[0028] In addition, such as Figure 4 As shown, the communication box 1 is equipped with a locking mechanism that drives the positioning plate 13 to move towards the support plate 15. The locking mechanism includes a disc 9, which provides a mounting carrier for the bolt 8, allowing the bolt 8 to be stably and spirally pushed forward, precisely acting on the positioning plate 13. The outer wall of the disc 9 is fixedly connected to the end of the connecting plate 11 away from the second support column 10. The middle of the disc 9 is spirally penetrated by a bolt 8 whose end abuts against the middle of the positioning plate 13. The bolt 8 can be rotated to adjust the clamping force, realizing fine adjustment of the distance between the positioning plate 13 and the support plate 15.

[0029] It is worth noting that, such as Figure 1 , Figure 3 and Figure 4As shown, the communication box 1 is equipped with a reset mechanism that drives the positioning plate 13 and the support plate 15 to slide into the communication box 1. The reset mechanism includes a pair of limiting slide grooves 101 on the communication box 1 corresponding to the ends of the drive rod 7. The limiting slide grooves 101 provide guidance for the movement of the ends of the drive rod 7, limit the sliding trajectory of the connecting rod 14, and ensure the stable movement of the positioning plate 13. Both ends of the limiting slide grooves 101 are provided with a first protruding plate 3 and a second protruding plate 4 fixedly connected to the communication box 1. The first protruding plate 3 provides a mounting base for the first reset spring 6 and assists in the stable operation of the reset mechanism. The second protruding plate 4 limits the extension range of the first reset spring 6 to ensure smooth reset of the drive rod 7. The middle of the first protruding plate 3 and the second protruding plate 4 are fixedly connected to a first support column 5. The first support column 5 provides sliding support for the drive rod 7 and also sleeves the first reset spring 6 to assist in the reset of the drive rod 7. The first reset spring 6 is movably sleeved on the first support column 5. When the first reset spring 6 releases its elastic force, it can drive the drive rod 7 back into the communication box 1 to achieve overall reset. The ends of the first support column 5 that are away from the second convex plate 4 all move through the ends of the drive rod 7.

[0030] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the end of the first return spring 6 away from the second convex plate 4 is also fixedly connected to the end of the corresponding drive rod 7. Both ends of the drive rod 7 are fixedly connected to a connecting rod 14 that moves through the limiting slide groove 101. The connecting rod 14 can slide along the limiting slide groove 101, transmitting the thrust of the drive rod 7 and driving the positioning plate 13 to move synchronously. The ends of the connecting rods 14 away from the drive rod 7 are fixedly connected to the positioning plate 13. The pair of first convex plates 3, second convex plates 4, first support columns 5, first return spring 6, connecting rods 14 and limiting slide grooves 101 are all symmetrically arranged with the inclined locking rod 72 as the center.

[0031] Furthermore, such as Figures 2 to 4As shown, the communication box 1 is also equipped with a latching mechanism for locking and resetting. The latching mechanism includes a pair of rotating supports 71 fixedly connected to the communication box 1. The rotating supports 71 provide rotational support for the tilting lever 72, allowing the tilting lever 72 to rotate around them, thereby locking and unlocking the drive rod 7. The tilting lever 72, which is pushed against by the drive rod 7 and rotates towards the communication box 1, is fixedly connected to the middle of the rotating supports 71. The tilting lever 72 can automatically latch the drive rod 7 under the action of the third reset spring 74, achieving positioning and locking; pressing the pressing rod 73 can rotate it to unlock it. The middle of the tilting lever 72 is fixedly connected to the pressing rod 73. Pressing the pressing rod 73 can drive the tilting lever 72 to rotate, releasing the lock on the drive rod 7. Its surface is provided with a pressing mark 75 for easy operation. A third return spring 74 is fixedly connected to the end of the pressing rod 73 away from the tilting latch 72. The release force of the third return spring 74 can drive the pressing rod 73 to return to its original position, so that the tilting latch 72 automatically locks the drive lever 7. The third return spring 74 is used to make the pressing rod 73 drive the tilting latch 72 to lock the drive lever 7. The upper surface of the end of the pressing rod 73 away from the tilting latch 72 is provided with a pressing mark 75. The pressing mark 75 is used to clearly indicate the pressing position, guide the operator to quickly find the unlocking point, and improve the convenience of operation.

[0032] In this embodiment, when using an electromagnetic shielding structure for a communication enclosure with anti-interference capabilities, after opening the inspection door 2 of the communication enclosure 1, pushing the drive rod 7 will cause the connecting rod 14 to slide along the limiting slide groove 101. Simultaneously, the connecting rod 14 will cause the positioning plate 13 to move away from the interior of the communication enclosure 1. During this process, the positioning plate 13 will compress the second return spring 12 on the second support column 10. When the drive rod 7 moves to the appropriate position, the tilting latch 72 at the rotating support 71 on the communication enclosure 1 will automatically lock the drive rod 7 under the elastic force of the third return spring 74, thus locking the position of the positioning plate 13. This eliminates the need for additional manual fixing, resulting in a quick and efficient operation.

[0033] If it is necessary to adjust the position of the positioning plate 13 or reset it, press the pressing rod 73 with the pressing mark 75. The pressing rod 73 will drive the tilting latch 72 to rotate around the rotating support 71, releasing the lock on the drive pull rod 7. At this time, the second reset spring 12 will release its elastic force, driving the positioning plate 13 to move closer to the inside of the communication box 1. At the same time, the drive pull rod 7 will reset synchronously with the positioning plate 13 through the connecting rod 14. If it is necessary to finely adjust the distance between the positioning plate 13 and the bearing plate 15, the bolt 8 in the middle of the disc 9 can be rotated. The end of the bolt 8 abuts against the middle of the positioning plate 13. By adjusting the screwing depth of the bolt 8, the position of the positioning plate 13 can be further fixed to ensure the stability of the equipment inside the communication box 1 and ensure the electromagnetic shielding effect.

[0034] When the positioning plate 13 and the drive rod 7 need to be retracted as a whole, the first reset spring 6 on the first support column 5 between the first convex plate 3 and the second convex plate 4 will release its elastic force, driving the drive rod 7 to slide into the communication box 1 along the limit slide groove 101. After the overall reset is completed, the maintenance door 2 can be closed.

[0035] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
