Embodiment 1

[0020] Such as figure 1 with figure 2 As shown, this embodiment includes a column 4 and baffles 1 symmetrically arranged on both sides of the column 4, the column 4 and the two baffles 1 are fixed on the ground by bolts, and the middle part of the column 4 has a movable cavity body 9, a motor 6 is installed in the column 4, the output end of the motor 6 is connected with a rotating shaft 5, the rotating shaft 5 can rotate freely in the movable cavity 9, and the two sides of the column 4 are also provided with rectangular holes communicating with the movable cavity 9 , two fence bodies 2 are set on the rotating shaft 5, the fence body 2 runs through the rectangular hole to close the gap between the column 4 and the baffle plate 1, the driving block 3 is fixedly installed on the rotating shaft 5, and the driving block 3 and the fence body 2 The position is configured such that when the rotating shaft 5 rotates in the forward and reverse directions, the drive block 3 is in cont...

Embodiment 2

[0023] Such as figure 1As shown, this embodiment is based on Embodiment 1, preferably, the spring 11 is a torsion spring. After the fence body 2 is fully opened, it is in contact with the spring 11 on the limit plate 10, and after the motor 6 stops power output, the kinetic energy carried by the fence body 2 itself gradually decreases, and the change is irregular, that is, the fence body 2 is opposite to the column. 4. The magnitude of the impact force varies greatly and the direction is inconsistent. The elastic strength of the torsion spring in each direction is relatively large. When buffering the impact of the fence body 2, the degree of damage to itself is low, and the present invention can ensure that the fence body 2 is continuously opened and closed. The higher service life of the various structural components increases the practicability of the present invention.

Abstract

The invention discloses an access control system, which includes a column and baffles arranged symmetrically on both sides of the column, a movable cavity is opened in the middle of the column, a motor is installed inside the column, and a rotating shaft is connected to the output end of the motor. It can rotate freely in the movable cavity, and also includes a first card swiping area and a second card swiping area arranged on the outer wall of the column. When the personnel enter and exit, the motor stops moving, and at the same time, the fence body contacts the spring on the limit plate and compresses it, and at the same time, the fence body contacts the travel switch to form a switch to control the external power supply to communicate with the electromagnet, so that the electromagnet is in a working state , the elastic force generated by the compressed spring recovery deformation pushes the fence body back, making the fence body return to its original shape, and re-closes the gap between the upright post and the baffle plate. At this time, the metal sheet on the fence body is attracted by the electromagnet, and makes both Maintain close contact, ensure that the entrance and exit of the construction site are restricted, and prevent unrelated foreign personnel from entering and exiting at will.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an access control system. Background technique [0002] The access control system refers to the prohibition authority of the "door", which is the guard against the "door". The "door" here, in a broad sense, includes various passages that can pass, including doors for people, doors for vehicles, etc. In the application of parking lot management, vehicle access control is an important means of vehicle management. It is not for the purpose of collecting parking fees, but mainly to manage vehicle entry and exit permissions. There are mainly two types of access control devices in the prior art, one is for long-term use, such as access control devices for office buildings, and the other is for temporary use, such as access control devices used in construction projects. Once the long-term use of access control equipment is constructed, it will not be dismantled and will be used all ...
