[0002] Nowadays, access control systems are becoming more and more popular in China. With the development of biometric technology, biometric systems in access control systems are also applied in more places. In today's access control systems, face recognition can be carried out through a display screen to control the entry and exit of personnel. The face recognition system is a biometric technology for identity recognition based on the facial feature information of a person. The camera captures an image containing a human face, automatically detects and tracks the face in the image, and then recognizes the detected face.

[0003] For the installation of the existing door access display screen, first, workers drill holes in the wall, then install the bracket on the wall, then connect the power cord to the back of the display screen main body, and then tighten and fix the bottom of the display screen main body and the bottom of the bracket through bolts to install the display screen main body on the bracket, so as to fix the display screen main body on the bracket and complete the installation of the door access display screen.

[0004] However, in the above installation method, in some installation environments, the space is relatively narrow, making it inconvenient to fix the bottom of the display screen main body with bolts.

Convex blocks are provided at both ends of the display screen main body, and the convex blocks are matched with the second grooves.

[0007] By adopting the above technical solution, through the convex bump spring and the inclined plate provided, when the staff needs to install the display screen for the door lock, the bracket is fixed on the wall where it needs to be installed, and then the display screen body is pushed into the bracket. The convex bumps provided will be squeezed when they come into contact with the inner wall of the bracket, and under the action of the spring, they will contract into the groove, and then under the action of the elastic force, the convex bumps will be reset, so as to be stuck in the second groove to fix the display screen body. Through the inclined plate and the vertical plate provided, when the display screen body is fixed in the second card slot, at this time the bottom end of the display screen body will touch the inclined plate, thereby pushing the inclined plate, and the inclined plate drives the vertical plate to achieve secondary fixation of the display screen body, making the fixation of the display screen body more stable, solving the problem that after the display screen is installed, it is easy to loosen and needs to be fixed by bolting, and the disassembly is rather troublesome.

[0008] The present utility model is further configured such that grooves are formed at both ends of the display screen body, and the grooves are matched with the convex bumps. A fixing block is provided in the groove, and a spring is sleeved on the outer wall of the fixing block, and one end of the spring is connected to the convex bump.

[0009] By adopting the above technical solution, the convex bumps provided will contract and reset under the action of the spring, so as to be engaged in the second groove to fix the display screen body.

[0010] The present utility model is further configured such that the number of the convex bumps is two groups, and one side of the convex bump is provided with an inclined surface.

[0011] By adopting the above technical solution, the two groups of convex bumps can make the display screen body more firmly fixed when being engaged, and the inclined surface setting reduces the friction force, making it easier to squeeze the convex bumps to contract them in the groove.

[0012] The present utility model is further configured such that the bottom of the display screen body is provided with an inclined surface, and the inclined surface is attached to the outer wall of the inclined plate.

[0013] By adopting the above technical solution, the inclined surface provided at the bottom can make the display screen body completely attached to the inclined plate when moving, so as to squeeze the inclined plate.

Connect the power cord to the back of the display screen main body 2, and then push the display screen main body 2 towards the bracket 1. During the pushing process, when the convex blocks 3 provided at both ends of the display screen main body 2 contact the inner walls at both ends of the bracket 1, they will be squeezed and thus contract into the grooves 6. Then continue to push the display screen main body 2 forward. When the convex blocks 3 contact the second grooves 9 provided at both ends of the bracket 1, the convex blocks 3 will be reset under the elastic force of the spring 8 and be clamped in the second grooves 9, achieving the fixing effect of the display screen main body 2. A sloping plate 11 is provided at the bottom of the bracket 1, and a vertical plate 12 is provided on one side of the sloping plate 11. The sloping plate 11 and the vertical plate 12 are located in the limiting groove 13. Convex blocks 3 are provided at both ends of the display screen main body 2, and the convex blocks 3 match the second grooves 9.

[0032] Please refer to Figure 2 - Figure 5 , grooves 6 are opened at both ends of the display screen main body 2, and the grooves 6 match the convex blocks 3. Fixing blocks 7 are provided in the grooves 6, and springs 8 are sleeved on the outer walls of the fixing blocks 7. One end of the spring 8 is connected to the convex block 3. When the display screen main body 2 is pushed forward, the convex blocks 3 provided at both ends of the display screen main body 2 will be squeezed and contract into the grooves 6 under the action of the spring 8. Then when contacting the second grooves 9, the convex blocks 3 will be reset under the action of the spring 8 and thus be clamped in the second grooves 9, achieving the fixing of the display screen main body 2.

[0033] Please refer to Figure 1 and Figure 2 , the number of the convex blocks 3 is two groups, and one side of the convex block 3 is arranged in an inclined plane. The two groups of convex blocks 3 provided can make the display screen main body 2 be fixed more firmly when being clamped, and the inclined plane setting makes the friction force between the convex block 3 and the inner wall of the bracket 1 decrease, making it easier to squeeze the convex block 3 to contract it in the groove 6.

[0034] Please refer to Figure 2 and Figure 3, the bottom of the display screen main body 2 is provided with an inclined surface, and the inclined surface is attached to the outer wall of the inclined plate 11. When the display screen main body 2 is fixed, the bottom inclined surface setting enables the display screen main body 2 to be completely attached to the inclined plate 11 when moving, thereby squeezing the inclined plate 11.

[0035] Please refer to Figure 5 , a lead groove 14 is provided on one side of the display screen main body 2. Through the provided lead groove 14, the circuit is connected to the lead groove 14 on one side of the display screen main body 2, enabling it to complete operation.

[0037] Please refer to Figure 1 and Figure 2 , a display screen 4 is provided on one side of the display screen main body 2, and a camera 5 is provided on one side of the display screen main body 2. Through the setting of the camera 5, when the access control is in use, face recognition can be directly performed through the camera 5, which is more convenient and fast.

[0038] The working principle of the present utility model is as follows: When installing the display screen for access control, the worker first drills a hole in the wall to be installed, then fixes the bracket 1 to the wall through bolts, then connects the power cord to the back of the display screen main body 2, and then pushes the display screen main body 2 towards the bracket 1. During the pushing process, the convex blocks 3 provided at both ends of the display screen main body 2 will be squeezed when they come into contact with the inner walls at both ends of the bracket 1, and thus contract into the grooves 6. Then continue to push the display screen main body 2 forward. When the convex blocks 3 come into contact with the second grooves 9 provided at both ends of the bracket 1, the convex blocks 3 will be reset under the elastic force of the spring 8 and snap into the second grooves 9, achieving the fixing effect of the display screen main body 2. At this time, the bottom of the display screen main body 2 will come into contact with the inclined plate 11 at the bottom of the bracket 1 during the pushing process, and the inclined plate 11 will be pushed backward by the bottom of the display screen main body 2 and displace in the limit groove 13, thereby driving the vertical plate 12 to displace, making the vertical plate 12 fit against the outer wall of the display screen main body 2, clamping the display screen main body 2, and performing secondary fixation, with a better fixing effect, thus completing the installation of the display screen for access control.
