Laser induction alarm for access control

Abstract

The invention discloses a laser induction alarm for an access control. The laser induction alarm comprises an access control body, a laser sensor, a storage battery and a buzzer, the access control body is in bolted connection with an outer box, a top plate is arranged at the top of the outer box, a bottom plate is arranged in the outer box, a first elastic spring is mounted at the bottom of the bottom plate, the left side and the right side of the bottom plate are each provided with a first rack, through grooves are formed in a protection plate and a pressure plate correspondingly, the lasersensor is arranged above the bottom plate, and a connecting hole is formed in the outer wall of the laser sensor. According to the laser induction alarm for the access control, the through grooves areformed in the protection plate and the pressure plate correspondingly, the connecting hole is formed in the outer wall of the laser sensor, the laser sensor is in bolted connection with the protection plate and the pressure plate, in this way, after the laser sensor is placed well, fixing between the laser sensor and the protection plate as well as between the laser sensor and the pressure platecan be conducted again, and the stability of the laser sensor during using is further ensured.

Description

technical field [0001] The invention relates to the related technical field of access control, in particular to a laser induction alarm for access control. Background technique [0002] As the name implies, access control refers to the interception equipment set up at the entrance and exit. It is mainly a system used to manage the entry and exit of people and vehicles, including doors for people and vehicles. Some access control will be equipped with alarms for Prevent people and vehicles from entering by mistake. [0003] But existing laser sensor siren still has some deficiencies in use, for example: [0004] 1. It is inconvenient to self-fix sensors of different sizes, which leads to inconvenience in the disassembly and assembly of the sensors, especially when the parts are damaged and need to be repaired. equipment flexibility; [0005] 2. Most of the alarms on the existing access control are exposed outside, without protective devices to protect them, they are easily...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a laser sensor alarm for access control, to solve the problem that the access control on the market is not convenient for self-fixation of sensors of different sizes, resulting in the disassembly operation of the sensors. It is inconvenient, especially when the parts are damaged and needs to be repaired. It is troublesome, which brings inconvenience to the operation of the staff and reduces the flexibility of the entire equipment. Moreover, most of the alarms on the existing access control are exposed, and there is no protective device. It protects and is easily damaged, which affects the efficiency of the siren, thereby reducing the practicality of the entire device.
