Through the provided meshing assembly 33, the driving assembly 11 and the combination rod, the lifting and lowering of the storage assembly 13 can be automatically completed, which is easy to operate and consumes less manpower. At the same time, the tooth column 19 climbs vertically upward or downward along the vertical tooth plate 6, and the annular cylinder 25 rotates continuously and wipes and lubricates the outer wall of the combination rod, so as to achieve the purpose of automatic lubrication and maintenance, improve the smoothness of the lifting and lowering of the storage assembly 13, avoid jamming, and improve the user experience.

[0017] Embodiment 2 On the basis of the first embodiment, the combination rod 1 and the combination rod 2 both include a threaded rod 10, the bottom end of the threaded rod 10 belonging to the combination rod 1 is fixedly connected to the vertical rod 8, the bottom end of the vertical rod 8 is rotatably connected to the top of the inner wall of the installation space 5, the bottom end of the threaded rod 10 belonging to the combination rod 2 is fixedly connected to the meshing gear 1, the outer wall of the meshing gear 1 is meshed with the meshing gear 2, one end of the meshing gear 2 is fixedly connected to one end of the output shaft of the motor, the motor is arranged at the bottom end of the inner wall of the installation space 5, a connecting belt 1 9 is transmission-connected between the outer walls of the two vertical rods 8, and the two ends of the inner wall of the installation space 5 are fixedly connected.

Under the connection of the connecting belt 1 9, the two vertical rods 8 and the threaded rod 10 all start rotating. Since the driving component 11 and the threaded rod 10 are in a threaded connection relationship, the support block 12 will support the storage component 13 to move up or down. Under the restriction of the two auxiliary slide bars 7, the overall displacement process will become smooth and smooth, and at the same time improve the stability of the storage component 13 during displacement.

[0019] Embodiment 3 On the basis of the second embodiment, the outer wall of the horizontal axis 16 is fixedly connected with a tooth column 19, and the tooth column 19 is in a meshing connection relationship with the vertical tooth plate 6. A square groove is provided at one end of the driving component 11, and a horizontal axis 2 17 is rotatably connected between the two ends of the inner wall of the square groove. The outer wall of the horizontal axis 2 17 is fixedly connected with a bevel gear 1 20, and the bottom end of the inner wall of the square groove is rotatably connected with a plane gear 22. The top of the plane gear 22 is fixedly connected with a bevel gear 21 that meshes with the outer wall of the bevel gear 20. A connecting belt 2 18 is transmission-connected between the outer walls of the horizontal axis 16 and the horizontal axis 2 17. A placement groove 24 and a square oil storage cavity 28 are provided inside the driving component 11. A rectangular through groove 23 that penetrates the placement groove 24 is provided at one end of the inner wall of the square groove. An oil filling port 1 31 and a small channel 30 are respectively provided on the top and one side inner wall of the square oil storage cavity 28. Two The oil filling port 2 35 is located far away from each other and symmetrically distributed. The oil filling port 2 35 and the oil filling port 1 31 are located on the same vertical line. The annular cylinder 25 is rotatably connected to the inside of the placement groove 24. The outer wall of the annular cylinder 25 is provided with an annular groove. The inside of the annular groove is fixedly connected with a gear ring 26. The outer wall of the planar gear 22 passes through the rectangular through groove 23 and is in a meshing connection with the gear ring 26. The outer wall of the annular cylinder 25 is provided with a narrow channel 29. The narrow channel 29 is located below the small channel 30. The inside of the annular cylinder 25 is provided with an annular oil storage chamber 34. The inside of the annular oil storage chamber 34 is connected to the narrow channel 29. The inner wall of the annular cylinder 25 is fixedly connected to a plurality of equidistantly arranged cleaning brushes 27. The inner wall of one side of the annular oil storage chamber 34 is provided with a plurality of equidistantly arranged horizontal channels 32. The inside of each horizontal channel 32 is connected to the inside of the horizontal channel 32 at the corresponding position.

[0020] When the support block 12 moves, the driving assembly 11 fixed on its outer wall will also move synchronously, and the tooth column 19 will climb or descend along the connecting belt 19, so that the horizontal shaft 16 will rotate synchronously and drive the horizontal shaft 2 17 to rotate synchronously through the connection of the connecting belt 2 18, and the plane gear 22 will rotate through the meshing bevel gear 1 20 and the bevel gear 2 21, and the meshing gear ring 26 will also rotate together, and drive the annular cylinder 25 to start rotating, and the cleaning brushes 27 on the inner wall of the annular cylinder 25 will continuously clean the threads in the rotating state. The rod is wiped. It should be noted here that: in the initial state, the interior of the square oil storage chamber 28 and the annular oil storage chamber 34 are filled with sufficient lubricating oil, and the lubricating oil will enter each cleaning brush 27 through each horizontal channel 32 to soak it. When the annular cylinder 25 rotates, a plurality of cleaning brushes 27 can automatically lubricate the outer wall of the threaded rod to reduce the occurrence of jamming. As the lubrication operation continues, the oil storage amount inside the annular oil storage chamber 34 gradually decreases, and the oil storage amount inside the annular oil storage chamber 34 gradually decreases through the narrow channel 29 opened. Figure 6It can be seen that the small channel 30 and the narrow channel 29 are both inclined. Because the square oil storage chamber 28 is located above the annular oil storage chamber 34, whenever the position of the narrow channel 29 passes through the small channel 30, a part of the lubricating oil in the square oil storage chamber 28 will enter the annular oil storage chamber 34 to gradually complete the automatic filling of the lubricating oil. When the position of the narrow channel 29 is staggered with the small channel 30, a small amount of lubricating oil in the square oil storage chamber 28 will pass through the small channel 30 and slowly flow downward along the inner wall of the placement groove 24, automatically lubricating the bottom end of the annular cylinder 25, the inner wall of the placement groove 24 and the rectangular through groove 23, thereby improving the smoothness of the operation of each linkage component and facilitating use. When the position of the storage component 13 rises to the highest point, the oil filling port 1 31 comes to the bottom of the oil filling port 2 35, and the lubricating oil can be replenished by a syringe or the like.

[0021] In actual use, the user gently presses the preset fingerprint on the fingerprint sensor, and the system immediately recognizes and verifies the user's identity. When the identity authentication is successful, the built-in microprocessor will respond quickly, and the drive motor will start, thereby driving the meshing gear 1 and the meshing gear 2 to start rotating. Under the connection of the connecting belt 1 9, the two vertical rods 8 and the threaded rod 10 all start rotating. Since the driving assembly 11 and the threaded rod 10 are in a threaded connection relationship, the support block 12 will support the storage assembly 13 to move up or down. During this process, the driving assembly 11 fixed on its outer wall will also move synchronously, and the tooth column 19 will climb or descend along the connecting belt 1 9. Then the horizontal axis 16 will rotate synchronously and through the connection of the connecting belt 2 18, the horizontal axis 2 17 will be driven to rotate synchronously, and through the meshing bevel gear 1 20 and the bevel gear 2 21, the plane gear 22 will rotate, and the meshing gear ring 26 will also rotate together, and drive the annular cylinder 25 to start rotating. Then the cleaning brushes 27 on the inner wall of the annular cylinder 25 will continuously lubricate and wipe the threaded rod in the rotating state, so as to achieve the purpose of automatic lubrication and maintenance, improve the smoothness of the storage assembly 13 when it is lifted and lowered, avoid jamming, and improve the user experience.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
