External protection device for intelligent community entrance guard lock

Abstract

The invention discloses an external protection device for an intelligent community entrance guard lock. The external protection device comprises fixed plates, a protection plate, moving blocks, a protection cover and square columns, wherein a groove is formed in the front face of the protection plate, a rotating shaft is arranged on one side inside the groove, the rotating shaft is sleeved with connecting blocks, and one sides of the connecting blocks are fixedly connected with the protection cover; fixed blocks are fixedly arranged in the middle of the upper end and the lower end inside the protection plate, the two sides of each fixed block are connected with the corresponding moving blocks through first springs, a cylinder is fixedly arranged on one side of each moving block, one end ofeach cylinder penetrates through the protection plate to be fixedly connected with the corresponding fixed plate, the back surfaces of the fixed plates are connected with the square columns through second springs, and supporting rods fixed to the square columns are installed around each second spring; and the ends, away from the square columns, of the supporting rods are inserted into the fixed plates, limiting blocks are installed in the square columns, and suckers are installed on the back surface of the square columns. The external protection device has the advantages that unlocking is carried out without integral taking, installation and disassembly are convenient, and shock absorption during impact is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent community door lock protection, in particular to an external protection device for an intelligent community door lock. Background technique [0002] The access control lock uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to hold the iron plate tightly to achieve the effect of locking the door. As long as a small current electromagnetic lock will produce a huge Magnetic force, the access control system that controls the power supply of the electromagnetic lock will cut off the power after the correct identification of the person, and the electromagnetic lock can open the door when it loses its suction. The access control lock needs to be protected. The general access control lock protection device is integrally covered on the access control lock. When opening the door, the protection d...
