The bottom of the threaded rod of the threaded sleeve assembly 6 is connected, the top of the threaded rod threaded sleeve assembly 6 is fixed to the top of the inner wall of the cylindrical card cover 7, the top of the cylindrical card cover 7 is fixed to the outside of the bottom of the table panel 2, and a transmission shaft 9 is installed horizontally through the bearing seat between the upper part of the inner wall of the cylindrical card cover 7 and the bottom of the table panel 2. The outer wall of the transmission shaft 9 is located on the inner side of the cylindrical card cover 7 and an L-shaped plate 10 is installed through a bearing. The upper part of the outer wall of the spline sleeve of the spline shaft spline sleeve assembly 5 is also installed with an L-shaped plate 10 through a bearing, and the top of the spline sleeve is connected to the end of the transmission shaft 9 through a bevel gear pair. The inner side of the table panel 2 The outer side of the workbench 1 is slidably fitted, specifically: the inner side of the table panel 2 is slidably fitted with the outer side of the workbench 1 through the universal ball installed with the embedded protrusion, reducing friction resistance and facilitating up and down movement. At the same time, an anti-collision strip is fixedly arranged around the top surface of the table panel 2. The anti-collision strip is made of elastic material. The anti-collision strip of the table panel 2 near the workbench 1 fills the gap between the outer side of the workbench 1 and the table panel 2, thereby improving safety and preventing debris from entering the gap. A drive shaft 11 is installed on the inner side of the bottom of the table panel 2 through a bearing seat for horizontal rotation front and back. The rear side of the outer wall of the drive shaft 11 is connected to the transmission shaft The outer ends of 9 are connected by a worm gear assembly 13, wherein the worm is coaxially fixed with the transmission shaft 9, and the worm wheel is fixedly sleeved on the driving shaft 11. The worm gear transmission has a self-locking function to prevent the worm wheel from rotating freely. The front side of the outer wall of the driving shaft 11 and the outer side surface of the workbench 1 are connected by a gear rack assembly 12, the gear is fixedly sleeved on the front side of the outer wall of the driving shaft 11, and the rack is vertically embedded in the outer side surface of the workbench 1.

[0021] See also Figure 3The lower middle part of the inner wall of the cylindrical cover 7 is expanded to form an expanded diameter section, and the top of the expanded diameter section and the top of the cylindrical base 3 are respectively matched and inserted with an embedded limiting ring 70, and the top of the outer wall of the expanded diameter section and the upper part of the outer wall of the cylindrical base 3 are threaded with limiting bolts 72 threaded with the limiting ring 70, and the relative surfaces of the upper and lower limiting rings 70 are inserted with telescopic elastic sleeves 71 through limiting circular grooves. The limiting bolts 72 squeeze and shrink the elastic sleeves 71, and the bottom of the outer wall of the cylindrical base 3 is welded with a connecting flange 30, which is fixed to the ground through stepped through holes and expansion bolts. When the cylindrical cover 7 rises, the telescopic elastic sleeve 71 is stretched to prevent debris from entering the installation space of the forward and reverse low-speed motor 8, and the outer diameter of the cylindrical cover 7 is consistent with that of the cylindrical base 3.

[0022] See also Figure 4 The relay control circuit includes a thermal relay FR1, relays KM1 and KM2, fuses FU1 and FU2 and an emergency stop button SB1; and the relay control circuit is connected to the mains via power terminals, a power cord and a plug. The power cord and the plug can be removed when not in use to avoid tripping the staff. The up button 14 and the down button 15 are connected in parallel and then connected in series to the relay control circuit via a spiral wire. The spiral wire is located between the table panel 2 and the cylindrical base 3 to connect the power, which can avoid knotting and entanglement.

[0023] When using a reception desk of the utility model: when the height of the table panel 2 needs to be adjusted, the rising button 14 or the falling button 15 can be manually pressed continuously, and then the relay KM1 or KM2 is energized, so that the forward and reverse low-speed motor 8 can be forward and reversed, and the spur gear pair is used to make the spline shaft spline sleeve assembly 5 forward and reverse, the threaded rod thread sleeve assembly 6 is extended and retracted, and the cylindrical card cover 7 moves up and down, so that the table panel 2 moves up and down. At the same time, the spline shaft spline sleeve assembly 5 can drive the transmission shaft 9 forward and reverse through the bevel gear pair and the L-shaped plate 10, and then the worm gear assembly 13 can make the drive shaft 11 forward and reverse, and the gear ratio design makes the gear ratio The speed at which the wheel meshes and moves up and down on the rack is consistent with the extension and retraction speed of the threaded rod threaded sleeve assembly 6. When the threaded rod threaded sleeve assembly 6 stops extending and retracting, the self-locking function of the worm gear assembly 13 can prevent the gear from moving up and down on the rack and is used for limiting. An up button 14 and a down button 15 are installed on the front and back surfaces of the table panel 2, allowing the user to operate at any time. Guests in wheelchairs can place their legs and part of the wheelchair under the table panel 2, further enhancing the comfort when communicating with the front desk staff, so that the front desk staff does not need to go around the outside of the workbench 1, thereby improving the work efficiency of the front desk staff and meeting the needs of aging-friendly design.
