Embodiment Construction
[0076] First, see Figure 2 to Figure 11 As shown, the electromagnetic door lock 60 disclosed in the present invention includes: an electromagnet assembly 20 and an adsorption assembly 30. In this embodiment, as Figure 8 , Figure 9As shown, the electromagnet assembly 20 is installed on the door frame 13, and the adsorption assembly 30 is installed on the door panel 14 correspondingly, but it is not limited thereto, and the electromagnet assembly 20 can also be installed on the door panel 14, and the adsorption assembly 30 is correspondingly arranged on the door frame 13, all can be implemented. However, the electromagnet assembly and the adsorption assembly belong to the prior art (Prior Art), and their internal detailed structure and connection with the external power supply are not the patent object of the present invention, and will not be described in detail.
[0077] The main feature of the present invention is that: the electromagnet assembly 20 is electrically conne...

The invention relates to an occlusion detection type energy-saving and power-saving device for an electromagnetic door lock. The occlusion detection type energy-saving and power-saving device for the electromagnetic door lock comprises an electromagnetic assembly and a corresponding adsorption assembly. The electromagnetic assembly is connected with an occlusion detection module. The adsorption assembly is provided with a suppression unit capable of abutting against the occlusion detection module. Thereby, when the door is closed, the electromagnetic assembly adsorbs the adsorption assembly with a magnetic force and allows the suppression unit suppressing the occlusion detection module; when the door is static, the electromagnetic door lock is in a low power consumption adsorption state; when a door plate is affected by external actions, the electromagnetic door lock returns to a lock state that is supplied by normal current rapidly by virtue of detection and trigger of the occlusion detection module, so as to achieve the function of taking account of saving energy and power and controlling external force detection.
Description
technical field [0001] The invention relates to an electromagnetic door lock, in particular to a blocking detection type energy-saving and power-saving device. Background technique [0002] In the access control monitoring system, the use of electromagnetic door locks is very common; figure 1 As shown, most of the current electromagnetic door locks 10 adopt the structure of an electromagnet 11 and an adsorption iron plate 12. The electromagnet 11 is arranged on the door frame 13, and the adsorption iron plate 12 is installed at the relative position of the door panel 14. When the electromagnet 11 Electricity generates electromagnetic suction, and the adsorption iron plate 12 is sucked, and then the electromagnetic door lock 10 forms a locked state (LOCK). When the electromagnet 11 is powered off, the electromagnetic attraction disappears, and the adsorption iron plate 12 can be separated from the electromagnet 11 at will, and the electromagnetic door lock is locked. The loc...
