Technical Field

The invention relates to the field of building construction, in particular to an entrance guard structure for a building safe passage.

Background

Disclosure of Invention

The invention aims to provide an entrance guard structure for a building safe passage, which ensures the normal operation of entrance guard identification and improves the reuse rate of an entrance guard system.

The purpose of the invention is realized by the following technical scheme:

an entrance guard structure for a building safety passage comprises an upright post and baffles symmetrically arranged on two sides of the upright post, wherein the upright post and the two baffles are fixed on the ground through bolts, a movable cavity is formed in the middle of the upright post, a motor is installed in the upright post, the output end of the motor is connected with a rotating shaft, the rotating shaft can freely rotate in the movable cavity, rectangular holes communicated with the movable cavity are formed in two sides of the upright post, two fence bodies are sleeved on the rotating shaft, the fence bodies penetrate through the rectangular holes to seal a gap between the upright post and the baffles, a driving block is fixedly installed on the rotating shaft, the positions of the driving block and the fence bodies are configured, and when the rotating shaft rotates in the positive and negative directions, the driving block is respectively contacted with the two fence bodies; still including setting up first district and the second district of punching the card on the stand outer wall, first district and the second district of punching the card is connected with the motor through the controller, install the limiting plate on the stand, install the spring and form the switch in the both sides of limiting plate, when the fence body is opened completely, the outer wall and the spring of fence body, form the switch contact, install the electro-magnet on two baffles, install on the fence body with electro-magnet assorted sheetmetal, the electro-magnet passes through the electric wire and is connected with the formation switch. When the barrier is in work, the upright post and the two baffles are respectively fixed on the ground at the inlet and the outlet and can be fixed by screws, when a person passing in and out of a building site swipes a card in a first card swiping area for verification, the first card swiping area is an inlet verification area, after the identity verification of the person entering the barrier is qualified, the controller controls the motor to rotate anticlockwise, the driving block fixed on the rotating shaft rotates reversely along with the rotating shaft until the driving block is contacted with the outer wall of the barrier body, and the driving block drives the barrier body to rotate freely in the movable cavity and the rectangular hole until the barrier body between the baffles and the upright post is completely opened; when the person goes out from the construction site, the card is held in the second card swiping area for identity verification, when the person who goes out passes the identity verification, the controller controls the motor to rotate clockwise, the driving block fixed on the rotating shaft rotates positively along with the rotating shaft until the driving block is contacted with the outer wall of the other fence body, the driving block drives the fence body to rotate freely in the movable cavity and the rectangular hole until the fence body between the baffle and the upright post is completely opened, so that the person can freely enter and exit in the construction site, after the person finishes the entering and exiting, the motor stops moving, the fence body is contacted with the spring on the limiting plate and compresses the spring, the fence body is contacted with the travel switch to form a switch to control an external power supply to be communicated with the electromagnet, so that the electromagnet is in a working state, and due to the lack of continuous power output of the motor, the elastic force generated by the compressed spring recovery deformation pushes back the fence body, so that, the gap between the upright post and the baffle is closed again, at the moment, the metal sheet on the fence body is attracted by the electromagnet, and the metal sheet and the electromagnet are kept in close contact, so that the entrance and the exit of the construction site are ensured to be in a limited state, and extraneous people are prevented from entering and exiting at will; the door control system is simple in structure, can be conveniently and quickly mounted and dismounted by adopting bolt fixing mode, can be used for being continuously used on another construction site after being dismounted after one construction site is completed, improves the reuse rate of the door control system, and reduces the cost of engineering management.

The central angle corresponding to the rectangular hole is 95-125 degrees. The rectangular hole is communicated with the movable cavity, so that the fence body can freely rotate in a certain range around the rotating shaft, the central angle corresponding to the rectangular hole is in the range of 95-125 degrees, 90-degree complete opening and closing of the fence body are guaranteed, meanwhile, a certain space is reserved for the fence body, the situation that the connecting part between the fence body and the rotating shaft is damaged due to direct rigid friction between the fence body and the rotating shaft is avoided, and the service life of the invention is further prolonged.

The spring is a torsion spring. The fence body is in contact with the spring on the limiting plate after being completely opened, and after the motor stops outputting power, the kinetic energy carried by the fence body is gradually reduced and irregularly changed, namely the impact force of the fence body on the upright post is greatly changed and inconsistent in direction, the elastic strength of the torsion spring in each direction is high, the damage degree of the torsion spring is low when the impact of the fence body is buffered, the high service life of each structural component of the invention can be ensured when the fence body is continuously opened and closed, and the practicability of the invention is improved.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. after people finish entering and exiting, the motor stops moving, meanwhile, the fence body is in contact with the spring on the limiting plate and compresses the spring, meanwhile, the fence body is in contact with the travel switch to form a switch to control an external power supply to be communicated with the electromagnet, so that the electromagnet is in a working state, due to the lack of continuous power output of the motor, the elastic force generated by the return deformation of the compressed spring pushes back the fence body, so that the fence body returns to an original state, the gap between the upright post and the baffle plate is closed again, at the moment, the metal sheet on the fence body is attracted by the electromagnet, and the metal sheet and the baffle plate are in close contact, so that an entrance and an exit of a construction site are ensured to be in a limited;

2. the central angle corresponding to the rectangular hole is in the range of 95-125 degrees, a certain space is reserved for the fence body while the fence body is completely opened and closed at 90 degrees, the damage to the connecting part of the fence body and the rotating shaft due to the direct generation of hard friction between the fence body and the rotating shaft is avoided, and the service life of the invention is further prolonged;

3. the torsion spring has higher elastic strength in all directions, the self damage degree is low when the impact of the fence body is buffered, the higher service life of each structural part can be ensured when the fence body is continuously opened and closed, and the practicability of the invention is improved.
