Description

Technical Field

[0001] The utility model relates to the technical field of height adjustment of face recognition equipment, and more specifically, to a height adjustment mechanism for face recognition equipment. Background Art

[0002] Face recognition technology has been widely used in various fields, such as security, attendance, payment, etc. In order to adapt to users of different heights, face recognition equipment needs to be equipped with a height adjustment mechanism. However, most of the existing height adjustment mechanisms use bolted connections to fix the equipment on brackets of different heights. This adjustment method has some inconveniences. First, bolt connections require the use of tools, such as wrenches or screwdrivers, which are relatively cumbersome to operate and not intuitive and convenient. Second, after the bolts are tightened, if the height needs to be adjusted again, the bolts must be loosened first, and then the position must be adjusted and then tightened again. The process is time-consuming and affects the efficiency of the equipment. In addition, frequent bolt disassembly and assembly may cause thread wear. After long-term use, problems such as bolt loosening and slipping may occur, affecting the stability and reliability of the equipment. Therefore, the existing height adjustment mechanism of face recognition equipment is insufficient in terms of convenience. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a height adjustment mechanism for face recognition equipment, which has the following beneficial effects:

[0016] 1.

At the same time, a guide strip is provided on the inner wall of the fixed sleeve, and a guide groove is provided on the side wall of the adjusting tube. The guide strip is slidably connected in the guide groove, which further limits the sliding direction of the adjusting tube and ensures the continuity and stability of the height adjustment.

[0028] See also Figure 1-5 A height adjustment mechanism for a face recognition device comprises a fixing sleeve 1, which is mounted on an external device. The fixing sleeve 1 is provided with an adjustment mechanism, which comprises an adjustment tube 2, a clamping rod 3, a transverse plate 4, a spring 5, a tension spring 6, an elastic strip 7, a guide mechanism and a limiting mechanism. The adjustment tube 2 is slidably connected in the fixing sleeve 1. A telescopic hole 8 is provided on the side wall of the fixing sleeve 1. The clamping rod 3 is slidably connected in the telescopic hole 8. A plurality of annular grooves 9 are equidistantly provided on the side wall of the adjustment tube 2. The clamping rod 3 is connected in the annular groove 9. A transverse plate 4 is mounted on the clamping rod 3. One end of the spring 5 is connected to the transverse plate 4. The other end of the spring 5 is connected to the side wall of the fixing sleeve 1. One end of the tension spring 6 is connected to the transverse plate 4. Both ends of the tension spring 6 are connected to the transverse plate 4. The segment is connected to the elastic strip 7, and the guiding mechanism and the limiting mechanism are respectively installed on the sub-fixed sleeve 1. The guiding mechanism includes a lateral plate 10 and a sliding block 11. The lateral plate 10 is installed on the side wall of the fixed sleeve 1. The two ends of the elastic strip 7 are respectively connected to the sliding block 11, and the sliding block 11 is slidably connected to the lateral plate 10. The side walls of the plurality of sliding blocks 11 are respectively provided with lateral strips 12, and the lateral plate 10 is provided with a lateral groove 13.

A guide strip 14 is provided on the inner wall of the fixed sleeve 1, and a guide groove 15 is provided on the side wall of the adjusting tube 2. The guide strip 14 is slidably connected in the guide groove 15.

[0029] In this embodiment, when adjusting the height, the adjusting tube 2 is first slidably connected in the fixing sleeve 1. Under the action of the spring 5, the clamping rod 3 can be driven to slide inward along the telescopic hole 8. Therefore, it is necessary to pinch the two sliding blocks 11 first, which will cause the elastic sheet to deform, and then drive the tension spring 6 to pull backward, thereby driving the clamping rod 3 to slide outward, and then slide the adjusting tube 2 inward to select the most suitable height, and then release the elastic strip 7 so that the clamping rod 3 is inserted into the corresponding annular groove 9, so that its height can be adjusted. The reciprocating sliding of the elastic strip 7 is guaranteed by the limiting of the lateral strip 12, and then the limiting of the adjusting tube 2 is guaranteed by the sliding of the guide groove 15 and the guide strip 14, thereby ensuring the continuity of the height adjustment.

[0030] See also Figure 2 , as an implementation method of a height adjustment mechanism for a face recognition device for a limiting mechanism: the limiting mechanism includes a threaded ring 16, two threaded rings 16 are provided, and the two threaded rings 16 are respectively threadedly connected to the fixing sleeve 1, and the two threaded rings 16 are respectively in contact with the side plate 10, and a plurality of anti-slip grooves 17 are opened on the side walls of the two threaded rings 16, and the plurality of anti-slip grooves 17 are respectively equidistantly arranged, a fixing plate 18 is provided on the adjusting tube 2, an adjusting frame 19 is provided on the fixing plate 18, and a camera 20 is provided on the adjusting frame 19.

[0031] More specifically, after adjusting the height, since the adjustment frame 19 is respectively connected to the adjustment tube 2 and the camera 20, the height can be adjusted to ensure the best position for face recognition. When it is necessary to limit the position of the sliding block 11, the sleeve 1 can be fixed through the threaded connection of the two threaded rings 16, and then the threaded rings 16 are placed on the side plate 10, thereby ensuring the limitation of the sliding block 11 and ensuring the continuity of use.

[0032] In summary, when the overall equipment is in use or running: when adjusting the height, first slide the adjusting tube 2 into the fixed sleeve 1, and under the action of the spring 5, the clamping rod 3 can be driven to slide inward along the telescopic hole 8, so it is necessary to pinch the two sliding blocks 11 first, which will cause the elastic sheet to deform, and then drive the tension spring 6 to pull backward, thereby driving the clamping rod 3 to slide outward, and then slide the adjusting tube 2 inward to select the most suitable height, and then release the elastic strip 7 so that the clamping rod 3 is inserted into the corresponding annular groove 9, so that its height can be adjusted, and the reciprocating sliding of the elastic strip 7 is guaranteed by the limiting of the lateral strip 12, and then the limiting of the adjusting tube 2 is guaranteed by the sliding of the guide groove 15 and the guide strip 14, thereby ensuring the continuity of the height adjustment.

[0033] After adjusting the height, since the adjustment frame 19 is respectively connected to the adjustment tube 2 and the camera 20, the height can be adjusted to ensure the best position for face recognition. When it is necessary to limit the position of the sliding block 11, the sleeve 1 can be fixed through the threaded connection of the two threaded rings 16, and then the threaded rings 16 are placed on the side plate 10, thereby ensuring the limitation of the sliding block 11 and ensuring the continuity of use.
