Embodiment 1

[0020] Such as figure 1 and 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, and the rotating shaft 5 can rotate freely in the movable cavity 9, and the two sides of the column 4 are also provided with a rectangle connected to the movable cavity 9 Holes, 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 so that when the rotating shaft 5 rotates in the forward and reverse directions, the drive block 3 contacts with th...

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. The access control system comprises a stand column, baffles, a first card swiping area and a second card swiping area, wherein the baffles are symmetrically arranged on two sides of the stand column; a movable cavity is formed in the middle part of the stand column; a motor is mounted in the stand column; the output end of the motor is connected with a rotation shaft; the rotation shaft is capable of freely rotating in the movable cavity; the first card swiping area and the second card swiping area are formed in the outer wall of the stand column. After people go in and out, the motor stops moving and fence bodies are in contact with springs on a limiting plate and are used for compressing the springs, and meanwhile, the fence bodies are in contact with travel switches which are then used for controlling an external power supply to be communicated with electromagnets, so that the electromagnets are in a working state; the fence bodies are ejected back by elasticity which is generated by return deformation of the compressed springs, so that the fence bodies return to the original state so as to seal gaps between the stand column and the baffles again, and meanwhile, a metal plate on each fence body is attracted by the corresponding electromagnet and is in close contact with the corresponding electromagnet so as to ensure that an exit of a construction site is limited and non-staff members are prevented from randomly going in and out of the construction site.

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 ...
