[0030] like Figure 3 The control component provides power to drive the stud 7 to move in the vertical direction, thereby driving the tray 3 and the face recognition attendance machine 4 fixed to the tray 3 to move, so as to be suitable for users of different heights, thereby improving the applicability of the face recognition attendance machine 4.

[0031] like Figure 3 and Figure 5The control assembly includes a driven bevel gear 8 which is arranged at the bottom of the control groove 5 and is rotatably connected to the control groove 5. A sleeve 9 is coaxially fixed at the middle position of the driven bevel gear 8. A threaded hole 10 is opened at the middle position of the inner cavity of the sleeve 9. The stud 7 extends into the sleeve 9 through the threaded hole 10 and is threadedly connected to the sleeve 9. A driving bevel gear 11 which meshes with the driven bevel gear 8 is also rotatably connected to the wall of the control groove 5. A transmission motor which drives the driving bevel gear 11 to rotate is fixed on the support 2.

[0032] like Figure 3 and Figure 5 The transmission motor provides power to drive the active bevel gear 11 coaxially fixed with the output shaft of the transmission motor to rotate. The rotation of the active bevel gear 11 will drive the driven bevel gear 8 meshing with the active bevel gear 11 to rotate, thereby driving the sleeve 9 coaxially fixed with the driven bevel gear 8 to rotate. The rotation of the sleeve 9 will drive the stud 7 threadedly connected to the sleeve 9 to move in the vertical direction.

[0033] like Figure 3 and Figure 5 The support 2 is provided with two guide grooves 12 which are arranged opposite to each other and communicated with the control groove 5 , a guide rod 13 is slidably connected in the guide groove 12 , one end of the guide rod 13 passes through the support 2 , and the part of the guide rod 13 passing through the support 2 is fixed to the tray 3 .

[0034] like Figure 3 and Figure 5 Two support plates 14 fixed to the support 2 are fixed outside the sleeve 9, and two guide tubes 15 arranged oppositely and axially are fixed on the support plate 14. The inner cavity of the guide tube 15 is hollow and open at both ends. The guide rod 13 extends to the part of the control groove 5 through which the guide tube 15 is passed, and the active bevel gear 11 passes through the support plate 14 and is rotatably connected to the support plate 14.

[0035] like Figure 3 and Figure 5 Through the cooperation of the guide tube 15 and the guide groove 12, the guide rod 13 is guided and limited, thereby guiding and limiting the movement of the tray 3 and the face recognition attendance machine 4, reducing the possibility of shaking of the face recognition attendance machine 4 during movement.

[0036] like Figure 1 and Figure 2 Two front columns 16 and two rear columns 17 are fixed at the four end corners of the upper end surface of the base plate 1, and each front column 16 and the adjacent rear column 17 are fixedly connected at one end away from the base plate 1 through a connecting seat 19.

By setting the ceiling cloth 18, the face recognition attendance machine 4 can be shielded from the sun and rain, reducing the possibility that outdoor light and rain will affect the use of the face recognition attendance machine 4.

[0037] like Figure 1 and Figure 2 The height of the front column 16 is lower than that of the rear column 17. The tops of the front column 16 and the rear column 17 and the connecting seat 19 are all inclined. A mounting box 20 with a hollow inner cavity is fixed on the two connecting seats 19. A driving component for driving the extension and retraction of the ceiling cloth 18 is provided in the mounting box 20. The driving component provides power to drive the extension and retraction of the ceiling cloth 18. When light is needed, the ceiling cloth 18 is retracted and does not block the face recognition attendance machine 4. When sunshade and rain protection are needed, the ceiling cloth 18 is unfolded to block the face recognition attendance machine 4.

[0038] like Figure 1 and Figure 2 The driving assembly includes a transmission shaft arranged in the middle position of the inner cavity of the installation box 20, both ends of the transmission shaft are rotatably connected to the inner cavity groove wall of the installation box 20, the ceiling cloth 18 is wound around the outside of the transmission shaft, one end of the ceiling cloth 18 is fixed to the circumferential outer wall of the transmission shaft, and a removal groove 21 is opened on the installation box 20, and the other end of the ceiling cloth 18 extends out of the installation box 20 through the moving groove. A baffle 22 is fixed to one end of the ceiling cloth 18 extending out of the installation box 20, and the size of the baffle 22 is larger than the size of the moving groove. The baffle 22 is connected to the connecting seat 19 through a guide assembly, and a control motor that drives the transmission shaft to rotate is fixed in the installation box 20.

[0039] like Figure 1 and Figure 2 , by controlling the motor to provide power, the transmission shaft is driven to rotate, and the rotation of the transmission shaft will drive the movement of the ceiling cloth 18. Since the connecting seat 19 is tilted, the ceiling cloth 18 will move under the action of gravity to block the face recognition attendance machine 4, and the movement of the ceiling cloth 18 is guided by the guide component.

[0040] like Figure 1 and Figure 2 and Figure 4 The guide assembly includes a tubular slide rail 23 fixed on the upper surface of the connecting seat 19, and each connecting seat 19 is provided with a fixed seat 24 with a C-shaped cross-section. The baffle 22 is fixedly connected to the two fixed seats 24, and a connecting shaft 25 is fixed on the fixed seat 24. The circumferential outer wall of the connecting shaft 25 is embedded with a movable roller 26 rotatably connected to the connecting shaft 25.

Through the cooperation of the moving roller 26, the tubular slide rail 23, the limiting roller 27 and the connecting seat 19, the movement of the baffle 22 and the ceiling cloth 18 is guided and limited.

[0042] like Figure 4 At the same time, through the cooperation of the moving roller 26, the tubular slide rail 23, the limiting roller 27 and the connecting seat 19, a windproof effect is played, thereby increasing the service life of the device.

[0043] like Figure 1 and Figure 2 A rainproof cover is fixed on the installation box 20 to shield the installation box 20.

[0044] When in use, the power is turned on, the switch is turned on, and when it is necessary to clock in, the staff member stands on the base plate 1 and clocks in through the face recognition attendance machine 4. When the staff member is taller or shorter and the height of the face recognition attendance machine 4 is not suitable, the staff member turns on the transmission motor, and provides power through the transmission motor to drive the active bevel gear 11 coaxially fixed with the output shaft of the transmission motor to rotate. The rotation of the active bevel gear 11 will drive the driven bevel gear 8 meshing with the active bevel gear 11 to rotate, and the active bevel gear 11 and the driven bevel gear 8 are both rotatably connected with the control slot 5. The rotation of the driven bevel gear 8 will drive the sleeve 9 coaxially fixed with the driven bevel gear 8 to rotate, and the rotation of the sleeve 9 will drive the stud 7 threadedly connected to the sleeve 9 to move in the vertical direction. The movement of the stud 7 will drive the tray 3 rotatably connected with the stud 7 to move in the vertical direction, and the movement of the tray 3 will drive the face recognition attendance machine 4 fixed with the tray 3 to move until the height of the face recognition attendance machine 4 matches the height of the user;

[0045] In the initial state, the baffle 22 moves to contact the outer wall of the installation box 20, and the ceiling cloth 18 is received in the installation box 20 and wound outside the transmission shaft. When the sunlight is strong or the weather is rainy and snowy and affects the normal use of the face recognition attendance machine 4, the control motor is turned on, and the power provided by the control motor will drive the transmission shaft coaxially fixed with the output shaft of the control motor to rotate. The rotation of the transmission shaft will drive the ceiling cloth 18 to move out of the installation box 20. Since the connecting seat 19 is tilted, the ceiling cloth 18 will move under the action of gravity until the ceiling cloth 18 is fully unfolded and the face recognition attendance machine 4 is blocked;

[0046] The movement of the ceiling cloth 18 will drive the movement of the baffle 22 fixed to the ceiling cloth 18, the movement of the baffle 22 will drive the movement of the fixed seat 24 fixed to the baffle 22, the movement of the fixed seat 24 will drive the moving roller 26 to slide on the tubular slide rail 23, and the limiting roller 27 is slidingly connected to the side wall of the connecting seat 19. Through the cooperation of the moving roller 26, the tubular slide rail 23, the limiting roller 27 and the connecting seat 19, the movement of the baffle 22 and the ceiling cloth 18 is guided and limited, and the impact of strong winds on the ceiling cloth 18 is reduced.
