Description

Technical Field

[0001] The utility model relates to the technical field of shielding cylinders, in particular to a shielding cylinder which is easy to clean. Background Art

[0002] Shielding cylinders play a vital role in many fields, including electronic equipment and communications facilities. They can effectively shield external electromagnetic interference, protect internal sensitive components, or prevent internal signal leakage. However, traditional shielding cylinders have some obvious problems in actual use.

[0003] Over time, dust and impurities tend to accumulate inside shielding cylinders. Due to the structural limitations of traditional shielding cylinders, their internal components are often difficult to disassemble, making it difficult for cleaning personnel to thoroughly clean the interior. This accumulation of dust and impurities not only affects the shielding effectiveness of the cylinder but can also damage the shielding materials within, reducing the overall performance and service life of the cylinder.

[0004] At the same time, the sealing performance of traditional shielding tubes is also insufficient. In complex working environments, impurities such as moisture, dust, and other impurities can easily enter the shielding tube through leaky seals, disrupting the stability of the internal environment. Alternatively, the shielding material inside may leak through poorly sealed areas, affecting the normal operation of the entire device. This is especially true in electronic equipment with strict environmental requirements, such as high-precision test instruments, where even a small amount of moisture or dust can cause deviations in measurement results.

[0005] Therefore, in order to solve the problems of traditional shielding tubes in terms of cleaning convenience and sealing performance, a new shielding tube design that is easy to clean is urgently needed to meet the requirements of modern electronic equipment and communication facilities for efficient cleaning and good sealing of shielding tubes.

The movable plate principle has one end of the pull spring fixedly connected to a pull rod, which is slidably connected to the limit box. The movable plate is subjected to the tension of the pull spring, and the slot in the movable plate wall can engage with the limit rod, thereby limiting the relative position of the shielding cover and the inner cylinder.

[0010] Preferably, the sealing assembly includes a sealing cover, the outer wall of which is fixedly connected to a rubber disc, a sealing groove being defined in the wall of the rubber disc, and the inner wall of the sealing cover being rotatably connected to a limit screw.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model is provided with a shielding assembly. The design of the shielding cylinder is convenient for cleaning operation. When cleaning is needed, the sealing assembly can be separated from the shielding assembly by rotating the limit screw, and then the moving block is used to slide on the inner wall of the outer cylinder, so that the shielding cover and the inner cylinder can be pulled out from the outer cylinder, the engagement between the card slot and the bayonet is released, and the limit box is further separated from the limit rod, and finally each component can be taken out separately for cleaning. This detachable design allows cleaning personnel to easily access various internal components and thoroughly clean parts such as the shielding cover and inner cylinder where dust and impurities may accumulate, effectively removing dirt remaining after long-term use, and ensuring that the performance of the shielding cylinder is not affected.

[0013] 2. This utility model utilizes a sealing assembly, with the inner wall of the sealing cover slidingly connected to the inner wall of the outer cylinder. The rubber disc on its outer wall engages the inner wall of the outer cylinder, while the sealing groove of the rubber disc slides into the outer wall of the shielding cover. When the sealing cover is installed, these components form a tight fit, and the rubber disc effectively fills the gap between the outer cylinder and the shielding cover, preventing external impurities such as dust and moisture from entering the shielding cover. This is crucial for protecting the internal shielding and maintaining the stability of the shielding cover's internal environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The outer wall of the outer cylinder 21 is fixedly connected to the top of the mounting base 1. The outer wall of the movable block 24 is slidably connected to the inner wall of the outer cylinder 21. The outer wall of the stop block 26 is slidably connected to the inner wall of the inner cylinder 23. The outer wall of the limit rod 25 is slidably connected to the inner walls of the inner cylinder 23 and the shielding cover 22. The bottom end of the limit rod 25 is provided with a bayonet 28. The inner wall of the limit box 27 is slidably connected to the movable plate 29. The wall of the movable plate 29 has symmetrical slots 211. The outer wall of the movable plate 29 is fixedly connected to a pull spring 210.

[0025] The inner wall of the limit box 27 is slidably connected to the outer wall of the limit rod 25 , the inner wall of the slot 211 is slidably connected to the outer wall of the limit rod 25 , and the end of the pulling spring 210 away from the movable plate 29 is fixedly connected to the inner wall of the limit box 27 .

[0026] The sealing assembly 3 includes a sealing cover 31 , the outer wall of the sealing cover 31 is fixedly connected to a rubber disc 33 , a sealing groove 34 is opened in the wall of the rubber disc 33 , and the inner wall of the sealing cover 31 is rotatably connected to a limiting screw 32 .

[0027] The inner wall of the sealing cover 31 is slidably connected to the inner wall of the outer cylinder 21 , the outer wall of the rubber disc 33 is slidably connected to the inner wall of the outer cylinder 21 , the inner wall of the sealing groove 34 is slidably connected to the outer wall of the shielding cover 22 , and the outer wall of the limiting screw 32 is threadedly connected to the inner wall of the outer cylinder 21 .

[0028] Working principle:

[0029] During use, the mounting base 1 serves as the foundation of the entire shielding cylinder, providing stable support for the shielding assembly 2. The shielding assembly 2 is the core part, with the shielding material placed inside the inner cylinder 23. The outer cylinder 21 is fixedly connected to the top of the mounting base 1, and the inner cylinder 23 is located at the center of the outer cylinder 21. The shield cover 22 is placed between the two, together forming a shielding structure.

[0030] When cleaning is required, first rotate the limiting screw 32 to disengage the sealing assembly 3 from the shielding assembly 2. At this time, the moving block 24 slides on the inner wall of the outer cylinder 21 to pull the shield cover 22 and the inner cylinder 22 out of the outer cylinder 21. At this time, by pulling the pull rod fixedly connected to the moving plate 29, the moving plate 29 is made to slide in the limiting box 27. Without the pull of the pulling spring 210, the card groove 211 in the wall of the moving plate 29 is no longer engaged with the card slot 28 on the limiting rod 25, so that the limiting box 27 is separated from the limiting rod 25. At this time, the block 26 is no longer in contact with the inner cylinder 23. When the limiting box 27 and the block 26 are both separated from the limiting rod 25, the limiting rod 25 is rotated to disengage the movable plate 29 threadedly connected thereto, so that the shield cover 22 and the inner cylinder 23 are no longer restricted and can be taken out separately for cleaning.

[0031] The sealing assembly 3 is used to seal the shielding assembly 2. The inner wall of the sealing cover 31 is slidably connected to the inner wall of the outer cylinder 23, and the rubber disc 33 fixed on its outer wall is also slidably connected to the inner wall of the outer cylinder 21. The sealing groove 34 in the wall of the rubber disc 33 is slidably connected to the outer wall of the shielding cover 22. When the sealing cover 31 is installed in place, the rubber disc 33 can effectively fill the gap between the outer cylinder 21 and the shielding cover 22 to achieve sealing. At the same time, the limiting screw 32 rotatably connected to the inner wall of the sealing cover 31 is threadedly connected to the inner wall of the outer cylinder 21. By rotating the limiting screw 32, the sealing cover 31 can be tightly fixed on the outer cylinder 21, further enhancing the sealing effect, preventing external dust, water vapor and other impurities from entering the interior of the shielding cylinder, and also preventing the internal shielding material from leaking or being contaminated, ensuring the normal operation and good performance of the shielding cylinder, and providing a reliable way for re-sealing after cleaning.
