Description

Technical Field

[0001] The utility model relates to the field of door access devices, in particular to a door access alarm structure. Background Art

[0002] With the continuous advancement of technology, people pay more and more attention to security monitoring alarms, and using door magnets to monitor illegal opening in the box access control system is a common safety device;

[0003] China Patent Authorization Application No.: CN201922334700.5 provides a security network monitoring box. The protective side buckle cover of the side heat dissipation louver of this solution prevents rain from invading the box. The gap between the top of the side buckle cover and the side of the box allows rainwater to flow vertically along the outer wall of the box through the heat dissipation holes of the side heat dissipation louver, and naturally flush the sponge filter above the air inlet at the bottom of the side buckle cover, achieving natural cleaning; air enters from the air inlet at the bottom of the side buckle cover, passes through the sponge filter, and enters the box through the louver. The heat generated by the internal electrical components drives the hot air flow to rise and be discharged through the rain cap outlet at the bottom edge of the rain cap at the top of the box to form a cycle, achieving heat dissipation.

[0004] The existing access control alarm structure has certain drawbacks when in use. First, when the access control alarm structure uses a door magnetic structure, most of the access control alarm structures are fixed on the outside of the box by threads, or the access control alarm structure is positioned by pasting when in use. This makes the access control alarm structure inconvenient to disassemble, and the pasting structure connection is not stable enough. For this reason, we propose an access control alarm structure.
