Problems solved by technology

[0002] There are two main ways for existing access cabinets to prevent the leakage of RFID signals (Radio Frequency Identification) in the cabinet; the first is to tightly compress the access cabinet door, so that the signal sealing strip between the cabinet door and the cabinet body is compacted. , in order to achieve the shielding of the RFID signal in the cabinet, but this method is not comfortable to close the door, requiring the user to use a lot of force to close the cabinet door completely, and the cabinet door will be slightly deformed after repeated use, resulting in a The signal sealing is not strong, resulting in signal leakage; the second is to transmit directional RF

Embodiment 1

[0036] Such as Figure 1-Figure 3 As shown, this embodiment provides an airtight structure for preventing signal leakage, including a male structure 1 and a female structure 2, a plurality of first protrusions 11 are arranged at intervals on the male structure 1; a plurality of first protrusions 11 are arranged at intervals on the female structure 2 The first groove 21, the plurality of first grooves 21 correspond to the plurality of first protrusions 11 one by one, the first protrusions 11 abut against the first grooves 21, and the first protrusions 11 and the first grooves The signal shielding surface 3 is formed at the abutment surface of the first protrusion 11 and the first groove 21 ; the signal absorption cavity 4 is formed at the gap between the first protrusion 11 and the first groove 21 .

[0037] In this embodiment, the public structure 1 is provided with two first protrusions 11 (such as figure 1 shown), the parent structure 2 is also provided with two first groov...

Embodiment 2

[0042] Such as Figure 4 As shown, this embodiment provides an access cabinet, including the airtight structure for preventing signal leakage in Embodiment 1. Specifically, the access cabinet also includes a cabinet body 100 and a cabinet door 200. The interior of the cabinet body 100 is hollow, and an open end is provided on one side, and the male structure 1 is fixedly installed on the outer periphery of the open end; The structure 2 is fixedly installed inside the cabinet door 200 , and the male structure 1 corresponds to the female structure 2 one by one. When the cabinet door 200 is closed, the first protrusion 11 abuts against the first groove 21 .

[0043] In this embodiment, the processing method of the cabinet body 100 is laser welding. The traditional arc welding cannot meet the technical requirements of signal shielding. The "mouth" type is fixedly installed on the inner side of the cabinet door 200. When the cabinet door 200 is closed, the first protrusion 11 abut...

Abstract

The invention belongs to the technical field of signal shielding and access cabinets, and discloses an anti-signal-leakage closed structure and an access cabinet. The anti-signal-leakage closed structure comprises a male structure and a female structure. The male structure is provided with a plurality of first bulges at intervals. A plurality of first grooves are formed in the female structure at intervals, the first grooves correspond to the first bulges in a one-to-one mode, the first bulges abut against the first grooves, and signal shielding faces are formed on the abutting faces of the first bulges and the first grooves. Signal absorption cavities are formed in the gaps between the first bulges and the first grooves. The signal shielding faces can effectively prevent signal leakage, and the signal absorption cavities can absorb leaked signals, so that complete shielding of the signals is realized. The access cabinet adopts the anti-signal-leakage closed structure. Signals emitted by an RFID signal transmitter in the cabinet can be completely shielded, and meanwhile, the comfort of a user when a cabinet door is closed is improved.

Description

technical field [0001] The invention relates to the technical field of signal shielding and access cabinets, in particular to an airtight structure for preventing signal leakage and an access cabinet. Background technique [0002] There are two main ways for existing access cabinets to prevent the leakage of RFID signals (Radio Frequency Identification) in the cabinet; the first is to tightly compress the access cabinet door, so that the signal sealing strip between the cabinet door and the cabinet body is compacted. , in order to achieve the shielding of the RFID signal in the cabinet, but this method is not comfortable to close the door, requiring the user to use a lot of force to close the cabinet door completely, and the cabinet door will be slightly deformed after repeated use, resulting in a The signal sealing is not strong, resulting in signal leakage; the second is to transmit directional RFID signals into the cabinet through a directional RFID signal transmitter.
