[0002] The facial recognition access control system is an offline or networked facial recognition access control and attendance system. It targets the mid-to-high-end access control and attendance market, replacing existing card and fingerprint access control systems. It uses a widely adopted regional feature analysis algorithm in facial recognition technology, integrating computer image processing techniques with biometric principles. It uses computer image processing to extract facial feature points from video, then applies biometric principles to analyze and create a mathematical model, known as a facial feature template. The generated facial feature template is then compared with the subject's facial image for feature analysis, generating a similarity score based on the analysis results. This score can be used to determine if the subject is the same person.

[0003] The access locks in the prior art are usually fixed on a wall or the ground. For example, the access locks in a residential area are fixed on the ground by a bracket, and the height of the bracket is generally fixed, which is difficult to meet the needs of users of different heights. In addition, the access locks are usually installed using bolts, and the access locks in the residential area are placed outdoors most of the time. After a long period of wind and sun, the bolts are prone to rust, making the access lock difficult to disassemble. Therefore, it is necessary to study a mounting bracket that can adjust the height of the access lock and facilitate the disassembly of the access lock to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 5 A mounting bracket for a face recognition access control lock includes a base plate 1 with threaded holes on the base plate 1. A square tube 2 is fixedly installed on the upper surface of the base plate 1. A square column 3 is inserted in the square tube 2. A mounting block 4 is fixedly installed on the top of the square column 3. A mounting groove 5 is opened on one side of the mounting block 4. Two sliding plates 6 are symmetrically slidably installed in the mounting groove 5. An L-shaped plate 7 is fixedly installed on one side of the two sliding plates 6. A lock body 8 is arranged between the two L-shaped plates 7. An adjusting component 9 for adjusting the height of the lock body 8 is provided in the square tube 2. A fixing component 10 for fixing the lock body 8 is provided in the mounting groove 5.

[0019] See also Figure 1 The adjustment component 9 includes a first spring 91 fixedly mounted on the upper surface of the base plate 1. The first spring 91 is arranged in the square tube 2, and the top of the first spring 91 is fixedly connected to the bottom end of the square column 3. The four sides of the square tube 2 are provided with a slide groove 92. An adjustment plate 93 is slidably installed between the two sides of the inner wall of the slide groove 92, and one side of the adjustment plate 93 is fixedly connected to one side of the square column 3.

[0020] See also Figure 4 The fixing assembly 10 includes a fixing rod 101 fixedly installed between the two sides of the inner wall of the mounting groove 5. The fixing rod 101 is in a vertical state. The two sliding plates 6 are both sleeved on the outer surface of the fixing rod 101. A second spring 102 is provided between one side of the sliding plate 6 and one side of the inner wall of the mounting groove 5. The second spring 102 is sleeved on the outer surface of the fixing rod 101.

[0021] See also Figure 5, one of the L-shaped plates 7 is symmetrically distributed on the left and right sides, and two limiting grooves 11 are provided. An insertion rod 12 is inserted in the two limiting grooves 11, and a circular plate 13 is fixedly sleeved on the outer surface of the insertion rod 12. A third spring 14 is sleeved on the outer surface of the insertion rod 12. The circular plate 13 and the third spring 14 are both arranged in the limiting groove 11, and one end of the third spring 14 is fixedly connected to one side of the circular plate 13, and the other end is fixedly connected to one side of the inner wall of the limiting groove 11. A splint 15 is fixedly installed on the end of the insertion rod 12 away from the limiting groove 11. The arrangement of the limiting groove 11, the insertion rod 12, the circular plate 13, the third spring 14 and the splint 15 can further improve the fixing effect of the lock body 8, and at the same time make the device suitable for lock bodies 8 of different sizes.

[0022] The two L-shaped plates 7 are then pulled away from each other, and the two L-shaped plates 7 drive the two sliding plates 6 to slide along the fixing rod 101 in the installation groove 5, squeezing the second spring 102 at the same time. At this time, the lock body 8 is placed between the two L-shaped plates 7. The L-shaped plates 7 are then released, and the rebound force of the second spring 102 is used to drive the two sliding plates 6 and the two L-shaped plates 7 to move closer to each other, thereby clamping and fixing the lock body 8 between the two L-shaped plates 7, thereby achieving the installation of the lock body 8. Conversely, if the size of the lock body 8 is large, the clamping plate 15 can be pulled so that the inserted rod 12 fixed on one side of the clamping plate 15 is withdrawn from the limiting groove 11, and at the same time, the circular plate 13 in the limiting groove 11 is driven to move out of the limiting groove 11 and stretch the third spring 14, and then the lock body 8 is placed between the two L-shaped plates 7. When the user needs to adjust the height of the lock body 8, the user directly presses the adjusting plate 93 downwards, and the adjusting plate 93 slides downwards in the slide groove 92, and at the same time drives the square column 3 to slide downwards in the square tube 2 and squeezes the first spring 91. When the square column 3 moves downwards, it will drive the mounting block 4, sliding plate 6, L-shaped plate 7 and lock body 8 to move downwards synchronously, thereby adjusting the height of the lock body 8. After the user completes face recognition, he directly releases the adjusting plate 93 and uses the rebound force of the first spring 91 to drive the square column 3 to move upwards in the square tube 2, so that the height of the lock body 8 returns to its initial state, and vice versa.
