Description

An adjustment device for a face recognition device Technical Field

[0001] This utility model relates to the field of facial recognition device adjustment technology, specifically an adjustment device for facial recognition devices. Background Technology

[0002] Facial recognition devices are technological devices that use facial features for identity verification or identification, and are widely used in security, access control, payment, and other fields. The following is detailed information about facial recognition devices.

[0003] Existing facial recognition devices are generally equipped with height adjustment mechanisms. For example, Chinese Patent Publication No. CN222352004U discloses a height adjustment mechanism for facial recognition devices. The adjustment tube is slidably connected inside the fixed sleeve. A snap-fit ​​rod is slidably connected inside the telescopic hole on the side wall of the fixed sleeve. The snap-fit ​​rod is connected to the annular groove on the side wall of the adjustment tube and is connected to the elastic strip through a transverse plate, a spring, and a tension spring. When the height needs to be adjusted, the sliding block is pinched, which causes the elastic strip to deform, pulling the tension spring and the snap-fit ​​rod to slide outward. Then, the adjustment tube is slid to the appropriate height, the sliding block is released, and the snap-fit ​​rod is inserted into the corresponding annular groove under the action of the spring, thus completing the height adjustment.

[0004] However, in the existing technology, there are two elastic strips, so when the locking lever is pulled out, both elastic strips need to be operated at the same time, which is cumbersome and cannot achieve synchronous operation of multiple locking levers. Therefore, those skilled in the art have proposed an adjustment device for face recognition equipment to solve the problems mentioned in the background. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustment device for a face recognition device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustment device for a face recognition equipment includes a base, a fixed cylinder mounted on the base, a top frame mounted on the top of the fixed cylinder, a sliding cavity formed inside the fixed cylinder, a movable rod slidably connected to the sliding cavity, a mounting frame mounted on the top of the movable rod, and a face recognition equipment mounted on the mounting frame. The device also includes:

[0008] A locking mechanism, which is arranged in a ring inside the fixed cylinder, is used to limit and fix the movable rod;

[0009] A synchronization mechanism, which is connected to a snap-fit ​​mechanism, is used to synchronize several snap-fit ​​mechanisms.

[0010] As a further embodiment of this utility model: the snap-fit ​​mechanism includes several annularly distributed inner cavities opened in the fixed cylinder, a spring is provided in the inner cavity, the spring is connected to a connecting block, the connecting block is fixedly connected to the snap-fit ​​rod, and the outer wall of the movable rod is provided with several spaced snap-fit ​​grooves corresponding to the snap-fit ​​rod.

[0011] As a further embodiment of this utility model: the synchronization mechanism includes a limiting rod installed in the inner cavity, a driving block slidably disposed on the limiting rod, the driving block being connected to the connecting block, an inclined groove being opened on the driving block, and a sliding column being slidably disposed in the inclined groove.

[0012] As a further improvement of this utility model: a plurality of sliding rods are slidably arranged in a ring and corresponding to the inner cavity on the top frame, the bottom end of the sliding rod is connected to the sliding column, and a pressure plate is installed on the top of the sliding rod.

[0013] As a further improvement of this utility model, a recessed cavity is provided inside the top frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model performs face recognition using a face recognition device mounted on a frame. When it is necessary to adjust the recognition height of the face recognition device, pressing the synchronization mechanism will simultaneously drive several locking mechanisms to release the limit on the movable rod, thereby allowing free adjustment of the extension length of the movable rod and realizing the height adjustment of the face recognition device. After the height adjustment is completed, releasing the press on the synchronization mechanism will cause the locking mechanism to automatically lock onto the movable rod, thus completing the height adjustment of the face recognition device. This utility model can achieve the synchronous operation of multiple locking mechanisms through a single pressing method, making the height adjustment of the face recognition device more convenient and improving its practicality.

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Please refer to Figures 1-3. An adjustment device for a face recognition device includes a base 1, a fixed cylinder 2 mounted on the base 1, a top bracket 3 mounted on the top of the fixed cylinder 2, a sliding cavity 4 formed inside the fixed cylinder 2, a movable rod 5 slidably connected to the sliding cavity 4, wherein the movable rod 5 is non-circular, a mounting bracket 6 mounted on the top of the movable rod 5, and a face recognition device 7 mounted on the mounting bracket 6. The device also includes:

[0021] A snap-fit ​​mechanism is arranged in a ring inside the fixed cylinder 2 to limit and fix the movable rod 5;

[0022] A synchronization mechanism, which is connected to a snap-fit ​​mechanism, is used to synchronize several snap-fit ​​mechanisms.

[0023] Face recognition is performed using the face recognition device 7 mounted on the mounting bracket 6. When the recognition height of the face recognition device 7 needs to be adjusted, the synchronization mechanism can be pressed. The synchronization mechanism will simultaneously drive several locking mechanisms to release the limit on the movable rod 5, thereby allowing the extension length of the movable rod 5 to be freely adjusted, thus realizing the height adjustment of the face recognition device 7. After the height adjustment is completed, the pressure on the synchronization mechanism is released, and the locking mechanism will automatically lock the movable rod 5, thus completing the height adjustment of the face recognition device 7. This utility model can realize the synchronous operation of multiple locking mechanisms through a single pressing method, making the height adjustment of the face recognition device 7 more convenient and improving its practicality.

[0024] In one embodiment, the snap-fit ​​mechanism includes several annularly distributed inner cavities 19 formed within the fixed cylinder 2. A spring 11 is provided within each inner cavity 19. The spring 11 is connected to a connecting block 10. The connecting block 10 is fixedly connected to the snap-fit ​​rod 9. The outer wall of the movable rod 5 is provided with several spaced snap-fit ​​grooves 8 that correspond to the snap-fit ​​rod 9.

[0025] In this embodiment, the locking rod 9 inside the inner cavity 19 is aligned with the locking groove 8 on the movable rod 5. Thus, in a natural state, the elastic force of the spring 11 will automatically push the connecting block 10, causing the connecting block 10 to push the locking rod 9 into the locking groove 8 of the movable rod 5, thereby limiting the movement of the movable rod 5.

[0026] In one embodiment, the synchronization mechanism includes a limiting rod 13 installed in the inner cavity 19, a driving block 12 slidably disposed on the limiting rod 13, the driving block 12 being connected to the connecting block 10, and an inclined groove 14 being provided on the driving block 12, with a sliding column 15 slidably disposed in the inclined groove 14.

[0027] The top frame 3 is slidably provided with a plurality of slide rods 16 arranged in a ring and corresponding to the inner cavity 19. The bottom end of the slide rod 16 is connected to the slide column 15, and the top of the slide rod 16 is equipped with a pressure plate 17.

[0028] In this embodiment, when the height of the face recognition device 7 needs to be adjusted, the pressure plate 17 can be pressed down. The pressure plate 17 will push the slide rod 16 to move downward, so that the slide post 15 at the bottom of the slide rod 16 will slide along the inclined groove 14 on the drive block 12, thereby pushing the drive block 12 to slide along the limit rod 13. Then, through the connecting block 10, the locking rod 9 will be driven to exit the locking groove 8 of the movable rod 5. Since the pressure plate 17 is connected to multiple slide rods 16, multiple locking rods can be achieved during the pressing down of the pressure plate 17. The synchronous movement of 9 allows multiple locking rods 9 to exit the locking slots 8 of the movable rod 5 simultaneously, resulting in better performance. After the height adjustment of the face recognition device 7 is completed, the pressure plate 17 is released. Under the elastic force of the spring 11, the connecting block 10 will push the locking rods 9 to automatically lock into the locking slots 8 of the movable rod 5. The connecting block 10 will also drive the drive block 12 to reset. At the same time, the slider will move back along the inclined groove 14 and push the slide rod 16 to rise, so that the slide rod 16 pushes the pressure plate 17 to rise, realizing the reset of the entire structure.

[0029] In one embodiment, the top frame 3 has a recess 18, which is provided to protect the outside of the pressure plate 17 and also to limit the top of the pressure plate 17.

[0030] This invention uses a face recognition device 7 mounted on a mounting bracket 6 for face recognition. When the recognition height of the face recognition device 7 needs to be adjusted, the synchronization mechanism can be pressed. The synchronization mechanism simultaneously drives several locking mechanisms to release the limit on the movable rod 5, thereby allowing free adjustment of the extension length of the movable rod 5 and realizing the height adjustment of the face recognition device 7. After the height adjustment is completed, the pressure on the synchronization mechanism is released, and the locking mechanism will automatically lock the movable rod 5, thus completing the height adjustment of the face recognition device 7. This invention can realize the synchronous operation of multiple locking mechanisms through a single pressing method, making the height adjustment of the face recognition device 7 more convenient and improving its practicality.
