[0002] With the acceleration of urbanization and the continuous increase in buildings, the completeness of building security systems has become increasingly important. Access control equipment, as a core component of building security, plays an irreplaceable role in protecting the lives and property of people within buildings and maintaining building management order. By verifying identity and controlling access permissions for personnel entering and exiting buildings, access control equipment can effectively prevent unauthorized entry, reduce theft, vandalism, and other security incidents, and accurately record personnel entry and exit information, providing reliable evidence for daily building management and security traceability. Whether in residential buildings, commercial office buildings, industrial plants, government agencies, or other building scenarios, access control equipment has become an indispensable security infrastructure, and its stability and reliability directly affect the overall protective effect of the building security system.

[0003] Most existing access control systems rely on municipal power for operation and lack reliable emergency power supply mechanisms or emergency unlocking schemes. In the event of a sudden power outage, the access control system will cease functioning, rendering the locks unable to unlock. This situation causes significant inconvenience to residents and office workers within the building. Utility Model Content

[0004] In view of the problem that access control systems stop working due to power outages, making it impossible to unlock access locks, this utility model proposes an access control device for building security to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an access control device for building security, comprising a body, a blocking component provided on the side of the body, a protective component provided on the outer surface of the body, and a telescopic component and a limiting component provided inside the body. The blocking component is divided into two parts, which are connected by the telescopic component. The limiting component is used to limit the height of the telescopic component.

[0006] Furthermore, the blocking assembly includes a motor, which is fixedly installed inside the body. The output shaft of the motor has a spline groove, and the output shaft of the motor is connected to a rotating shaft through a telescopic assembly and the spline groove.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-6 As shown, this utility model is an access control device for building security, including a body 1. A blocking component 2 is provided on the side of the body 1, a protective component 3 is provided on the outer surface of the body 1, and a telescopic component 4 and a limiting component 5 are provided inside the body 1. The blocking component 2 is divided into two parts, which are connected by the telescopic component 4. The limiting component 5 is used to limit the height of the telescopic component 4.

[0021] During normal use, the identification module inside the body 1 identifies the correct identity information, which causes the barrier component 2 to work and open, allowing personnel to enter and exit normally. In the event of an unexpected power outage, security personnel can open the protective component 3, release the limiting component 5 inside the body 1 from limiting and fixing the telescopic component 4, pull the telescopic component 4 upward to move it, causing the two parts of the barrier component 2 to separate, and then push the telescopic component 4 to rotate the movable part of the barrier component 2, which will open and allow personnel to enter and exit normally.

[0022] This utility model connects the barrier component 2 and the telescopic component 4. The barrier component 2 is divided into two parts, and the telescopic component 4 is set between the two parts of the barrier component 2, so that the two parts of the barrier component 2 can rotate at the same time. In the event of an accidental power outage, the telescopic component 4 can be pulled to separate it from the power source of the barrier component 2. The telescopic component 4 can be manually pushed to drive the moving part of the barrier component 2 to rotate, so that the barrier component 2 can be opened, thus ensuring that the normal entry and exit of personnel is not affected.

[0023] In one embodiment, the blocking component 2 includes a motor 201, which is fixedly installed inside the body 1. The output shaft of the motor 201 has a spline groove 202. The output shaft of the motor 201 is connected to a rotating shaft 203 via a telescopic component 4 and the spline groove 202. A baffle 204 is fixedly connected to the outer surface of the rotating shaft 203.

[0024] After the identification module inside the machine body 1 identifies the correct personnel information, it starts the motor 201. The output shaft of the motor 201 drives the rotating shaft 203 to rotate through the telescopic component 4 and the spline groove 202. The rotating shaft 203 can drive the baffle 204 to rotate, so that the two sets of baffles 204 move away from each other and open the passage for personnel to pass through.

[0025] In one embodiment, the protective component 3 includes a protective plate 301, which is rotatably connected to the body 1. A rotating seat 302 is rotatably connected to the outer surface of the protective plate 301. A locking plate 303 is fixedly connected to the outer surface of the rotating seat 302. A slot 304 is provided on the outer surface of the rotating seat 302. A support piece 305 is fixedly connected to the inside of the body 1. A locking groove 306 is provided inside the body 1.

[0026] Insert the key into the slot 304 within the rotating base 302, and rotate the key to drive the rotating base 302 and the support plate 305, causing the support plate 305 to rotate out of the locking slot 306, releasing the limiting fixation between the body 1 and the protective plate 301. At this point, the protective plate 301 can be pulled to rotate and open. The support plate 305 inside the body 1 is used to support the protective plate 301 when it is closed.

[0027] In one embodiment, the telescopic component 4 includes a telescopic shaft 401, a spline shaft 402 fixedly connected to the lower end of the telescopic shaft 401, a handle 403 fixedly connected to the upper end of the telescopic shaft 401, both the telescopic shaft 401 and the spline shaft 402 being rotatably connected to the rotating shaft 203, the spline shaft 402 being inserted into the spline groove 202, and a circular plate 404 fixedly connected to the outer surface of the telescopic shaft 401.

[0028] In the normal position, the splined shaft 402 is located inside the spline groove 202. After the motor 201 is started, the motor 201 drives the telescopic shaft 401 and the rotating shaft 203 to rotate through the spline groove 202 and the splined shaft 402. The rotating shaft 203 drives the baffle 204 to open and close. When the telescopic shaft 401 slides upward, the splined shaft 402 at the lower end of the telescopic shaft 401 can be retracted into the rotating shaft 203, and the connection between the splined shaft 402 and the rotating shaft 203 drives the rotating shaft 203 to rotate.

[0029] In one embodiment, the limiting component 5 includes a sliding plate 501, a limiting plate 502 is fixedly connected to the outer surface of the sliding plate 501, the sliding plate 501 and the limiting plate 502 are both slidably connected inside the body 1, a spring 503 is fixedly connected to the outer surface of the limiting plate 502, and the end of the spring 503 is fixedly connected inside the body 1.

[0030] After opening the protective plate 301, push the sliding plate 501 to move, causing the sliding plate 501 to drive the limiting plate 502 to move. The limiting plate 502 compresses the spring 503 and separates from the telescopic shaft 401. At this time, the handle 403 can be pulled to drive the telescopic shaft 401 and the spline shaft 402 to move upward, so that the circular plate 404 on the outer surface of the telescopic shaft 401 passes over the sliding plate 501, and the spline shaft 402 is retracted into the rotating shaft 203. Then, release the sliding plate 501, and the spring 503 pushes the limiting plate 502 and the sliding plate 501 to reset. The sliding plate 501 is located below the circular plate 404, supporting the circular plate 404 and the telescopic shaft 401. The spline shaft 402 at the lower end of the telescopic shaft 401 separates from the spline groove 202. Push the handle 403 to drive the rotating shaft 203 and the baffle 204 to rotate through the spline shaft 402, realizing the manual opening and closing of the channel.

[0031] In one embodiment, for the aforementioned sliding plate 501, a push plate 6 is fixedly connected to the top of the sliding plate 501.

[0032] The push plate 6 is configured to provide a point of force for pushing the sliding plate 501, making it easier to move the sliding plate 501.

[0033] In one embodiment, the top of the protective plate 301 is provided with a groove 7.

[0034] The groove 7 is designed to provide a point of force for rotating the protective plate 301, making it easier to open and close the protective plate 301.

[0035] Through the above technical solution, 1. By connecting the barrier component 2 and the telescopic component 4, the barrier component 2 is divided into two parts, and the telescopic component 4 is located between the two parts of the barrier component 2, so that the two parts of the barrier component 2 rotate simultaneously. In the event of an unexpected power outage, pulling the telescopic component 4 separates it from the power source of the barrier component 2, and manually pushing the telescopic component 4 drives the moving part of the barrier component 2 to rotate, so that the barrier component 2 opens, thus ensuring that personnel can enter and exit normally without being affected; 2. Through the sliding plate 501 The connection between the circular plate 404 and the sliding plate 501 is such that, in the normal position, the circular plate 404 is located below the sliding plate 501, and the sliding plate 501 presses down on the circular plate 404 to prevent the circular plate 404 and the telescopic shaft 401 from moving upward and causing the spline shaft 402 to come out of the spline groove 202. When the baffle 204 is manually opened, the circular plate 404 is located above the sliding plate 501, and the sliding plate 501 supports the circular plate 404 and the telescopic shaft 401 to prevent the spline shaft 402 at the lower end of the telescopic shaft 401 from being inserted into the spline groove 202.
