Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door access controllers, in particular to a door access controller. Background Art
[0002] The access control system, also known as the access management control system, is developed on the basis of the traditional door lock. The access controller is the core of the system. It uses the combination of modern computer technology and various identification technologies to embody an intelligent management method. In order to avoid the access controller from being damaged by collision during use, which leads to abnormal control of the access switch, most of the access controllers are fixed in a protective box to protect the protective box. However, when the protective box is hit by the outside world, it cannot well absorb the impact force generated by the collision, which can easily affect the access controller. Eventually, the internal components of the access controller will be damaged by the impact force generated by the collision, affecting the service life of the access controller. In addition, the access controller will generate a certain amount of heat when in use, especially in the hot summer season. The heat cannot be dissipated in the protective box, and the heat accumulates, which can easily damage the internal components of the access controller due to the heat in the protective box, further affecting the service life of the access controller. Therefore, we have launched a new access controller. Utility Model Content
