Description

Technical Field

[0001] This utility model relates to the technical field of shielding boxes, specifically to a shielding box flip-door structure with controllable angle. Background Technology

[0002] In scenarios such as electromagnetic compatibility (EMC) testing of electronic equipment and wireless signal shielding, shielding boxes are key devices used to isolate external electromagnetic interference, ensure the purity of the testing environment, or achieve signal shielding. Among them, the flip door is an important component of the shielding box, and its structural design directly affects the ease of use, shielding effectiveness, and operational safety of the shielding box. When existing shielding boxes are opened, the cover is fully opened. Sometimes, during maintenance work, it is not necessary to open the cover completely; only opening the cover to a certain angle is required for inspection. Fully opening the cover allows humid air from the outside to enter the interior of the shielding box. To address the aforementioned deficiencies, existing technology (Chinese patent announcement number CN217037834U, announcement date 2022-07-22) provides an angle-controllable shielding box flip-door structure. During use, the operator opens the cover from one side of the shielding box using a latch. As it opens, the first locking plate slides downwards on the inner side of the first sliding groove. At this time, the sliding rod slowly moves out from the inner side of the support rod. When it reaches the appropriate position, the operator rotates the nut using a baffle, slowly pushing the washer forward. The washer's limiting block slides on the inner side of the threaded rod's limiting groove, fixing the sliding rod and preventing movement. This fixes the angle of the cover, allowing the operator to inspect the interior of the shielding box.

[0003] The above solution requires tightening nuts to fix the tilting door every time the angle is adjusted. This is time-consuming and cumbersome, and consumes time and labor costs. Furthermore, the shielding plate and mounting base are easily damaged during disassembly and maintenance. The threads of the nuts are also prone to wear and tear over time, which affects the locking of the tilting door after adjustment and is not conducive to subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide an angle-controllable shielding box flip door structure to solve the problem mentioned in the background art that the existing angle-controllable shielding box flip door structure requires tightening nuts to fix the flip door angle every time it is adjusted. This operation is time-consuming and cumbersome, consuming time and labor costs. Moreover, the shielding plate and mounting base are easily damaged during disassembly and maintenance. The threads of the nuts are prone to wear and tear during long-term use, which affects the locking of the flip door after adjustment and is not conducive to subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-controllable shielding box flip door structure, including a shielding box body, wherein a flip door body is rotatably mounted on the front side of the shielding box body via a hinge.

[0006] A connecting frame is fixed to the top rear side of the flip door body. The connecting frame is slidably connected to the slide groove. The slide groove is opened on the top left side of the shielding box body. Positioning holes are opened at equal angles on the top of the connecting frame. A pin is slidably connected through the top left side of the shielding box body. The bottom of the pin is engaged with the positioning hole.

[0007] Sealing bags are laid around the four edges of the opposite sides of the flip door body and the shielding box body.

[0008] Furthermore, both the connecting frame and the sliding track are configured as arc-shaped structures, and the connecting frame and the sliding track are concentrically set with the flipping point of the flipping door body.

[0009] Furthermore, a spring is provided between the pin and the top of the shielding box body, and the pin forms a positioning and fixing structure with the positioning hole through the spring.

[0010] Furthermore, the shielding box body has symmetrically fixed protrusions on the front sides of the top and bottom, and the protrusions cooperate with the grooves, which are correspondingly opened on the top and bottom of the rear side of the flip door body.

[0011] Furthermore, an air reservoir is installed in the groove, the protrusion is in contact with the air reservoir by compression, the air reservoir is connected to a sealing bladder through a connecting tube, and the sealing bladder is configured as a rectangular structure.

[0012] Furthermore, the flip door body is composed of a surface metal shielding layer, a middle insulating buffer layer and a bottom metal shielding layer. The surface metal shielding layer is made of nano-silver copper alloy material, the middle insulating buffer layer is made of polyimide foam material, and the bottom metal shielding layer is made of manganese zinc ferrite magnetic material.

[0013] Furthermore, the surface of the surface metal shielding layer is provided with a nano-level anti-oxidation coating, which is a silicon dioxide-titanium oxide composite coating.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This angle-controllable shielding box flip door structure allows for convenient adjustment of the flip door's angle during use. The simple operation saves manpower and time costs, facilitates later equipment maintenance and upgrades, and increases the sealing between the flip door and the shielding box when closed. It also enhances the shielding performance of the flip door itself, improving the electromagnetic shielding performance of the shielding box and ensuring the stable operation of data center equipment.

[0015] Furthermore, when adjusting the angle of the flip door body, first pull the pin on the top of the shielding box body, which will stretch the spring and separate the pin from the positioning hole in the initial position. Then the angle of the flip door can be adjusted, and the connecting frame will slide in the slide groove. After positioning, release the pin, and the spring will drive it to move down and reset, thereby engaging with the positioning groove in the corresponding position on the connecting frame, and thus locking the adjusted state.

[0016] Furthermore, after the flip door body and the shielding box body are closed, the protruding strip will be inserted into the corresponding groove, thereby squeezing the air storage bag in the groove. After being compressed, the air storage bag will transport the gas inside to the sealing bag. After the sealing bag expands, it will fill the gap between the flip door body and the shielding box body, improve the use effect of the device, and avoid interference from external factors.

[0017] Furthermore, the nano-silver-copper alloy possesses excellent conductivity and oxidation resistance. In high-frequency electromagnetic environments, it can quickly sense and generate reverse current to counteract external electromagnetic interference. Polyimide foam is lightweight, has good insulation properties, and can buffer and absorb energy, effectively reducing the weight of the shielding plate. At the same time, it isolates the upper and lower metal shielding layers to prevent short circuits and can also buffer external vibrations and impacts to prevent the shielding plate from cracking due to stress. Manganese-zinc ferrite has a good shielding effect on low-frequency magnetic fields. Combined with the surface metal shielding layer, it achieves all-round shielding against high and low frequency electromagnetic interference.

[0018] Furthermore, the nano-level anti-oxidation coating is a silicon dioxide-titanium oxide composite coating, which has excellent anti-oxidation and anti-corrosion properties, effectively isolating air and moisture from contact with the metal surface and extending the service life of the shielding plate.
