Description

Technical Field

[0001] This utility model relates to the field of intelligent security access control technology, and in particular to an intelligent security access control device. Background Technology

[0002] A security access control system is an electronic system designed for security purposes, controlling the entry and exit of personnel into a specific area. It integrates electronic, information, and mechanical technologies, using physical barriers at entrances and exits and identity verification to effectively manage and control personnel access, preventing unauthorized entry and thus ensuring the safety of people and property within the designated area. It typically consists of access controllers, card readers, electric locks, door magnets, buttons, communication equipment, and management software.

[0003] For the installation of some security access control systems, especially turnstiles, it is generally necessary to install the base in the groove in the ground in advance, and then install the main body of the turnstile and fix it with bolts. During this process, the operator needs to bend over to operate, and when maintenance is needed later, it is also necessary to bend over to remove the bolts, which increases the difficulty of operation. Based on this, an intelligent security access control device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an intelligent security access control device that effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides an intelligent security access control device, including a base and an access control body. The edge of the top surface of the base is bent upwards, and multiple protrusions are installed on its top surface. A limit seat and a limit frame are installed in the middle of the top surface of the base, and a vertically placed connecting tube is rotatably installed between the two. An operating rod is rotatably installed at the top of the connecting tube. Two first connecting rods are symmetrically installed at the bottom of the outside of the connecting tube. The ends of the two first connecting rods that are far apart are rotatably connected to second connecting rods. U-shaped guide seats are installed on both sides of the top surface of the base, and both of them are slidably installed inside. The access control system includes two limiting pins, each with a limiting protrusion at its center. A spring is installed between the limiting protrusion and the inner wall of the U-shaped guide seat. The adjacent ends of the two limiting pins are rotatably connected to the ends of two second connecting rods. Limiting plates are fixedly installed on the top surfaces of both U-shaped guide seats. Limiting portions that mate with the protrusions are installed on the bottom surface of the inner wall of the access control body. An operating groove is formed in the center of the top surface of the access control body. The top end of the connecting tube and the operating rod are located inside the operating groove. A protective plate is snapped into the inside of the operating groove. Limiting tubes that mate with the limiting pins are installed on both sides of the inner wall of the access control body.

[0006] Preferably, the tops of the multiple protrusions are provided with bevels, and the outer walls of the multiple protrusions are respectively attached to the inner walls of the access control body and the inner walls of the limiting part. The bevels in this solution can reduce the thickness of the tops of the multiple protrusions. When the access control body is installed with the base, it can make contact first and limit the connection between the access control body and the base, ensuring smooth installation. At the same time, it improves the accuracy of the connection between the limiting pin and the limiting tube. As the protrusions enter the interior of the limiting part, the access control body has a certain tilting performance, ensuring the stability of the access control body installation.

[0007] Preferably, both ends of the limiting seat and the bottom end of the limiting frame are fixedly connected to the base with screws. A gap is left between the bottom end of the limiting frame and the ends of the two first connecting rods. This solution avoids motion interference between the two first connecting rods and the limiting frame when they rotate. As the connecting tube rotates, the two first connecting rods pull the limiting pins through the second connecting rod, ensuring that the two limiting pins slide out from the inside of the limiting tube, making it easy for the operator to lift the access control unit as a whole.

[0008] Preferably, in any of the above solutions, the end of the operating rod is rotatably connected to the top of the connecting tube by a pin, and a gap is left between the other end of the operating rod and the inner wall of the operating groove. This solution facilitates providing a gripping position for the operator, makes full use of the lever structure, drives the connecting tube to rotate at a certain angle, and then makes the two first connecting rods rotate synchronously, and pulls the two limit pins through the two second connecting rods.

[0009] Preferably, in any of the above embodiments, two limiting slots are provided on both sides of the operating groove, and buckles that cooperate with the limiting slots are provided on both sides of the protective plate. In this embodiment, the top of the protective plate has a stepped structure, extending downwards on all four sides and fitting against the inner wall of the limiting slot, thereby improving the installation stability of the protective plate. In addition, the four corners of the top surface of the protective plate are rounded to improve the appearance. The protective plate is also made of engineering plastic, which is easy to mold and process, and allows the four buckles to be bent at a certain angle, making it convenient for operators to install and disassemble the protective plate later.

[0010] This utility model has the following advantages:

[0011] 1. This intelligent security access control device comprises a base, an access control body, a U-shaped guide seat, a spring, and a limiting pin. The spring pushes the limiting pin into the interior of the limiting tube through a limiting protrusion ring. Simultaneously, the other end of the limiting pin is connected to the end of the first connecting rod via a second connecting rod. An operating rod is rotatably mounted on the top of the connecting tube. By gripping the operating rod, the connecting rod is rotated horizontally. The two first connecting rods are pulled by the second connecting rod, causing the limiting pin to slide out from the interior of the limiting tube, thus facilitating the overall lifting of the access control body. This allows for quick assembly and disassembly of the access control body. The overall structure is simple and easy to operate. Compared to traditional bolt connections, it can greatly save operation time and reduce operation difficulty.

[0012] 2. This intelligent security access control device consists of an access control body and a protective plate. The top surface of the access control body has an operating groove, and the inner wall of the operating groove has a limit slot. The sides of the protective plate are equipped with buckles, which facilitates the easy disassembly of the protective plate. When the access control is in normal use, the protective plate is installed inside the operating groove to seal the operating groove, improves aesthetics, and prevents external personnel from accidentally touching the operating lever.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 7 As shown, an intelligent security access control device includes a base 1 and an access control body 2. The edge of the top surface of the base 1 is bent upward to form a stepped structure, and multiple protrusions 16 are installed on its top surface. A limiting seat 18 and a limiting frame 12 are installed in the middle of the top surface of the base 1. The limiting seat 18 is a hollow structure, and the limiting frame 12 extends upward. A vertically placed connecting pipe 4 is rotatably installed between the two. The top of the connecting pipe 4 is slotted, and an operating rod 5 is rotatably installed inside it. Two first connecting rods 15 are symmetrically installed at the bottom of the connecting pipe 4 near the limiting seat 18. The ends of the two first connecting rods 15 that are far apart are rotatably connected to a second connecting rod 9.

[0023] U-shaped guide seats 7 are installed on both sides of the top surface of the base 1, and limit pins 8 are slidably installed inside both. Limiting rings 20 are provided in the middle of the two limit pins 8. Springs 19 are installed between the limiting rings 20 and the inner wall of the U-shaped guide seats 7. The adjacent ends of the two limit pins 8 are rotatably connected to the ends of the two second connecting rods 9 respectively. Limiting plates 17 are fixedly installed on the top surface of the two U-shaped guide seats 7. The internal size of the U-shaped guide seats 7 is larger than the outer diameter of the springs 19 and the limiting rings 20, so that the limit pins 8 can be pulled and the limiting rings 20 can compress the springs 19. During this process, the lengths of the two second connecting rods 9 are different, but as the two first connecting rods 15 rotate, they can synchronously drive the two limit pins 8 to slide.

[0024] The bottom surface of the inner wall of the access control body 2 is equipped with a limiting part 10 that cooperates with the protrusion 16. An operating groove 11 is opened in the middle of the top surface of the access control body 2. The top end of the connecting pipe 4 and the operating rod 5 are located inside the operating groove 11. A protective plate 3 is snapped into the inside of the operating groove 11. Limiting tubes 6 that cooperate with the limiting pin 8 are installed on both sides of the inner wall of the access control body 2.

[0025] The main body of the access control unit 2 is made of stainless steel sheet welded together to ensure its structural stability. The main body of the access control unit 2 is also equipped with a facial recognition display screen, camera, card reader, control motherboard and other structures. The control motherboard is interconnected with the external network via network cable. The control motherboard integrates a microcontroller and related control circuits and power supply circuits to facilitate information transmission and comparison, and to provide stable power support for the facial recognition display screen, camera and card reader.

[0026] The tops of the multiple protrusions 16 are all provided with bevels. The outer walls of the multiple protrusions 16 are respectively attached to the inner walls of the access control body 2 and the inner walls of the limiting part 10. As an optional technical solution of this utility model, the bevels can reduce the thickness of the tops of the multiple protrusions 16. When the access control body 2 is installed with the base 1, it can make contact first and limit the connection between the access control body 2 and the base 1, ensuring the smooth installation. At the same time, it improves the accuracy of the connection between the limiting pin 8 and the limiting tube 6. As the protrusions 16 enter the interior of the limiting part 10, the access control body 2 has a certain tilting performance, ensuring the stability of the installation of the access control body 2.

[0027] Both ends of the limiting seat 18 and the bottom end of the limiting frame 12 are fixedly connected to the base 1 by screws. A gap is left between the bottom end of the limiting frame 12 and the ends of the two first connecting rods 15. As an optional technical solution of this utility model, this avoids the two first connecting rods 15 from interfering with the movement of the limiting frame 12 when they rotate. As the connecting tube 4 rotates, the two first connecting rods 15 pull the limiting pins 8 through the second connecting rod 9, ensuring that the two limiting pins 8 slide out from the inside of the limiting tube 6, so that the operator can lift the access control body 2 as a whole.

[0028] The end of the operating lever 5 is rotatably connected to the top of the connecting tube 4 by a pin. A gap is left between the other end of the operating lever 5 and the inner wall of the operating groove 11. As an optional technical solution of this utility model, this facilitates providing a gripping position for the operator, making full use of the lever structure to drive the connecting tube 4 to rotate at a certain angle, thereby causing the two first connecting rods 15 to rotate synchronously, and pulling the two limiting pins 8 through the two second connecting rods 9.

[0029] Two limiting slots 13 are provided on both sides of the operating groove 11. The protective plate 3 is provided with buckles 14 on both sides that cooperate with the limiting slots 13. As an optional technical solution of this utility model, the top of the protective plate 3 is a stepped structure, extending downward on all four sides and fitting against the inner wall of the limiting slots 13, thereby improving the installation stability of the protective plate 3. In addition, the four corners of the top surface of the protective plate 3 are rounded to improve the appearance. The material of the protective plate 3 is also made of engineering plastic, which is easy to mold and process, and allows the four buckles 14 to be bent at a certain angle, making it convenient for operators to install and disassemble the protective plate 3 later.

[0030] This intelligent security access control device requires the following steps to use:

[0031] 1) During installation, remove the protective plate 3;

[0032] 2) Raise the height of the access control unit 2 and completely cover the limit frame 12 and the connecting pipe 4 within it;

[0033] 3) Align the access control body 2 and the base 1, and at the same time, the operator's hand grips the operating 5 along the operating groove 11;

[0034] 4) Rotate the operating lever 5 to make the first connecting rod 15 rotate synchronously, which drives the two limit pins 8 to move in opposite directions through the second connecting rod 9 and compresses the spring 19;

[0035] 5) The protrusions 16 on the base 1 enter the interior of the limiting part 10, and then the operating rod 5 is released. The spring 19 pushes the limiting pin 8, so that the limiting pin 8 and the limiting tube 6 are stably engaged, and the quick connection is completed.

[0036] In summary, when in use, the user utilizes the base 1, access control body 2, U-shaped guide seat 7, spring 19, and limiting pin 8. Spring 11 pushes the limiting pin 8 into the interior of the limiting tube 6 via the limiting protrusion ring 20. Simultaneously, the other end of the limiting pin 8 is connected to the end of the first connecting rod 15 via the second connecting rod 9. An operating rod 5 is rotatably mounted on the top of the connecting tube 4. By gripping the operating rod 5, the connecting rod 4 rotates horizontally. The two first connecting rods 15 are pulled by the second connecting rod 9, causing the limiting pin 8 to slide out from inside the limiting tube 6, thus facilitating the overall lifting of the access control body 2. The system achieves the purpose of quick assembly and disassembly of the access control body 2. The overall structure is simple and easy to operate. Compared with traditional bolt connections, it can greatly save operation time and reduce operation difficulty. The system is composed of the access control body 2 and the protective plate 3. The top surface of the access control body 2 is provided with an operation groove 11. The inner wall of the operation groove 11 is provided with a limit slot 13. The sides of the protective plate 3 are equipped with buckles 14, which facilitates the disassembly of the protective plate 3. When the access control is in normal use, the protective plate 3 is installed inside the operation groove 11 to seal the operation groove 11, improve the aesthetics, and prevent external personnel from accidentally touching the operating lever 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
