Description

Technical Field

[0001] The utility model relates to the technical field of intelligent door locks, in particular to a door lock with an intelligent identity recognition function. Background Technique

[0002] An intelligent door lock refers to a composite lock improved on the basis of a traditional mechanical lock, which is more intelligent and simpler in terms of user security, identification, and management. It is an execution component for locking doors in an access control system. Common intelligent door locks include magnetic card locks, fingerprint locks, iris recognition locks, etc. They are widely used in banks, government departments, hotels, etc.

[0003] After retrieval, an intelligent door lock based on identity recognition disclosed in a Chinese patent with the publication number CN210049716U includes a housing. The housing is divided into a left accommodation cavity and a right accommodation cavity by a partition plate. A telescopic cylinder is arranged in the right accommodation cavity. One end of the main shaft of the telescopic cylinder is provided with a limiting groove. A cam is sleeved on the main shaft of the telescopic cylinder. An annular sliding groove is arranged outside the cam, and a strip-shaped sliding groove is arranged on one side of the cam. A rotating shaft is arranged on the right accommodation cavity, and a limiting block is arranged at the rear end of the rotating shaft. A lock shaft is arranged in the left accommodation cavity. A sliding block is arranged at the right end of the lock shaft. A limiting part is arranged on the lock shaft in the left accommodation cavity. A rack is arranged on the lock shaft. The left accommodation cavity is rotatably connected with a second rotating shaft, and a gear is coaxially installed at the front end of the second rotating shaft. An identity information acquisition device is arranged on the front side of the front panel of the housing, and a main control board is installed on the front panel of the housing. The utility model has the characteristics of simple structure, convenient operation, smooth operation, etc. Its technical key points are as follows:

[0004] Although the above scheme can identify the identity, there are still some deficiencies in the actual use process. For example, during the identification, since the position of the intelligent lock body is relatively low and the shooting angle of the identification structure cannot be adjusted, it is necessary to bend down when performing face recognition. Once the identification time is relatively long, it will cause discomfort to the user.

[0005] Therefore, we propose a door lock with an intelligent identity recognition function to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a door lock with an intelligent identity recognition function to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A door lock with an identity intelligent recognition function includes an intelligent lock body. A control panel is fixedly installed on the front surface of the intelligent lock body. A circular groove is formed on the front surface of the intelligent lock body. An adjusting circular plate is provided on the inner wall of the circular groove.

[0024] Please refer to Figures 1-5, in the present utility model, a door lock with an intelligent identity recognition function includes an intelligent lock body 1. An operation panel 2 is fixedly installed on the front surface of the intelligent lock body 1. A circular groove 5 is formed on the front surface of the intelligent lock body 1. An adjusting circular plate 7 is provided on the inner wall of the circular groove 5. A through opening 11 is formed on the front surface of the intelligent lock body 1. A housing 6 is fixedly connected to the inner wall of the intelligent lock body 1. Two rotating rods 16 are rotatably connected to the inner wall of the housing 6 through two bearings. A connecting seat 12 is fixedly connected to the ends of the two rotating rods 16 close to each other. A face recognition camera 15 is fixedly installed on the inner wall of the connecting seat 12. Two support plates 9 are fixedly connected to the outer surface of the connecting seat 12. An arc-shaped toothed plate 8 is fixedly connected to the ends of the two support plates 9 away from the connecting seat 12. A control rod 13 is rotatably connected to the left and right side surfaces of the housing 6 through two bearings. A gear 14 is fixedly connected to the outer surface of the control rod 13. The gear 14 meshes with the arc-shaped toothed plate 8. The left end of the control rod 13 is fixedly connected to the right side surface of the adjusting circular plate 7.

[0025] In this embodiment, an installation frame 4 is fixedly connected to the front surface of the intelligent lock body 1. A tempered glass sheet 3 is fixedly connected to the inner wall of the installation frame 4. By providing the cooperation of the installation frame 4 and the tempered glass sheet 3, dust prevention can be carried out for the through opening 11 to prevent dust from entering the interior of the intelligent lock body 1.

[0026] In this embodiment, two limiting rings 17 are fixedly connected to the outer surface of the control rod 13. The two limiting rings 17 are respectively fixedly connected to the left and right side surfaces of the gear 14. By providing the limiting rings 17, the gear 14 can be strengthened, the stability of the gear 14 can be increased, and the loosening of the gear 14 can be prevented.

[0027] In this embodiment, two baffle plates 10 are provided inside the housing 6. The side surfaces of the two baffle plates 10 close to the arc-shaped toothed plate 8 are respectively fixedly connected to the upper surface of the arc-shaped toothed plate 8 and the right side surface of the arc-shaped toothed plate 8. By providing the baffle plates 10, the arc-shaped toothed plate 8 can be limited, the separation of the arc-shaped toothed plate 8 from the gear 14 can be prevented, and the phenomenon that the connecting seat 12 cannot be controlled can be avoided.

[0028] In this embodiment, the arc-shaped toothed plate 8 is coaxial with the rotating rod 16, and the control rod 13 is coaxial with the adjusting circular plate 7. By the coaxiality of the arc-shaped toothed plate 8 and the rotating rod 16, it can be ensured that the arc-shaped toothed plate 8 can mesh with the gear 14, and the coaxiality of the control rod 13 and the adjusting circular plate 7 can avoid the collision between the adjusting circular plate 7 and the circular groove 5 during the rotation of the adjusting circular plate 7, resulting in a jamming phenomenon.

A brake ring 20 is fixedly connected to the outer surface of the control rod 13. Two springs 21 are fixedly connected to the bottom surface of the brake plate 19. The bottom end of each spring 21 is fixedly connected to the inner bottom wall of the housing 6. Through the elastic force of the spring 21, the brake plate 19 can be moved upward, so that the brake plate 19 and the brake ring 20 can cooperate to limit the control rod 13 and prevent the control rod 13 from automatically rotating during use.

[0030] The working principle of the present utility model is as follows:

[0031] During use, the user can rotate the adjustment circular plate 7, so that the adjustment circular plate 7 drives the control rod 13 to rotate. The control rod 13 rotates and drives the gear 14 to rotate. The gear 14 can control the connecting seat 12 to rotate around the rotating rod 16 through the meshing action with the arc-shaped tooth plate 8, so that the connecting seat 12 drives the face recognition camera 15 to rotate, thereby completing the angle adjustment of the face recognition camera 15. Thus, it is not necessary for the user to bend down, and it is convenient to recognize the face. After adjustment, through the elastic force of the spring 21, the spring 21 can push the brake plate 19 upward to contact the brake ring 20 and limit the control rod 13 to prevent the control rod 13 from driving the gear 14 to rotate during use.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. The narrative mode of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
