[0029] Example 1

[0030] See also Figure 1-5 The utility model provides a technical solution: a leisure chair driving and lifting combined device that is easy to disassemble, comprising:

[0031] The lifting assembly 100 and the mounting plate 300 are installed at the bottom of the leisure chair. A mounting ring is fixed to the outer ring surface of the top of the mounting plate 300, and the upper surface of the mounting ring is provided with six second mounting holes 400 in a circular array for facilitating the installation of the mounting plate 300 at the bottom of the leisure chair, so as to facilitate the installation of the mounting plate 300 at the bottom of the leisure chair.

[0032] The lifting assembly 100 is mounted on the base of the leisure chair. The lifting assembly 100 includes a bottom plate 101 mounted on the base of the leisure chair, and a top plate 102 disposed on the upper surface of the bottom plate 101. Six hydraulic rods 103 are disposed on the upper surface of the bottom plate 101 for lifting the top plate 102. Each group of two hydraulic rods 103 is a group, and three groups of hydraulic rods 103 are disposed in a circular array on the upper surface of the bottom plate 101.

[0033] A first rotating frame 104 corresponding to the hydraulic rod 103 is fixedly provided on the upper surface of the bottom plate 101, and a second rotating frame 105 corresponding to the hydraulic rod 103 is fixedly provided on the lower surface of the top plate 102.

[0034] Three fixed cylinders 106 are fixed on the upper surface of the base plate 101 in a circular array, and the inner walls of the three fixed cylinders 106 are slidably provided with limiting columns 107, and the top ends of the limiting columns 107 are fixedly connected to the lower surface of the top plate 102. The setting of the limiting columns 107 and the fixed cylinders 106 effectively ensures the stability of the up and down movement of the top plate 102 during lifting adjustment.

[0035] The lower surface of the bottom plate 101 is provided with three first mounting holes 108 in a circumferential array for facilitating the mounting of the bottom plate 101 to the base of the leisure chair.

[0036] In this embodiment, by providing the lifting assembly 100 , the device can achieve stable lifting and adjustment of the height of the leisure chair when lifting and adjusting the height of the leisure chair.

[0037] Example 2

[0038] Based on the first embodiment, and different from the first embodiment,

[0039] A conveniently disassembled leisure chair driving and lifting combined device further comprises:

[0040] The installation component 200 is used to quickly install the lifting component 100 and the leisure chair base. The installation component 200 includes a plug-in column 201 fixed on the upper surface of the top plate 102, and a plug-in groove 202 provided on the lower surface of the installation plate 300 and adapted to the plug-in column 201. The outer surface of the plug-in column 201 is provided with four cylindrical cavities 203 in a circumferential array, and the interior of the plug-in column 201 is provided with an installation cavity 204. The inner wall of the cylindrical cavity 203 is provided with a threaded column 205 extending into the interior of the installation cavity 204. The inner bottom wall of the installation cavity 204 is fixed. A motor 206 is provided, and a driving bevel gear 207 is fixedly provided at the output end of the motor 206. The ends of the four threaded columns 205 are fixedly provided with driven bevel gears 208 that mesh with the driving bevel gear 207. The mounting assembly 200 also includes four positioning columns 209 that are slidably arranged on the inner walls of the four cylindrical cavities 203 respectively. A cylindrical thread groove 2011 is provided at the end of the positioning column 209, and the outer surface of the threaded column 205 is threadedly connected to the inner wall of the cylindrical thread groove 2011, so that the positioning column 209 can be automatically moved by the rotation of the threaded column 205.

[0041] A limiting block 2012 is fixed to the end of the positioning column 209, and a limiting groove 2013 for the limiting block 2012 to slide is opened on the inner bottom wall of the cylindrical cavity 203, which effectively ensures the stability of the positioning column 209 during movement.

[0042] The inner side wall of the insertion slot 202 is provided with positioning slots 2010 in a circular array that match the four positioning posts 209 .

[0043] In this embodiment, by setting up the installation component 200, the motor 206 can be started to achieve rapid disassembly of the leisure chair and the lifting component 100. During installation, the motor 206 can be started to reverse to achieve rapid fixation of the installation plate 300 and the plug-in column 201, thereby achieving the purpose of rapid disassembly and installation of the lifting component 100 from the leisure chair.

[0044] During operation, when the height of the leisure chair is lifted and adjusted, the lifting and adjustment of the height of the leisure chair can be achieved through the extension and retraction of the three hydraulic rods 103. At the same time, during the lifting process, the top plate 102 can drive the limiting column 107 to slide on the inner wall of the fixed cylinder 106 when it moves up and down, thereby effectively ensuring that the top plate 102 moves straight up and down, thereby effectively ensuring the stability of the leisure chair during lifting and adjustment. Moreover, when it is necessary to disassemble the lifting component 100, the motor 206 can be started to drive the active bevel gear 207 to rotate. The rotation of the active bevel gear 207 drives the four driven bevel gears 208 to rotate, thereby driving the four threaded columns 205 to rotate at the same time. The simultaneous rotation of the four threaded columns 205 in the cylindrical thread groove 2 Under the action of 011, the four positioning columns 209 are driven to move toward the middle at the same time, so that the positioning columns 209 are disengaged from the positioning grooves 2010 and enter the interior of the cylindrical cavity 203. Finally, the leisure chair is lifted upward to achieve rapid disassembly of the leisure chair and the lifting component 100. Moreover, during installation, the installation plate 300 of the leisure chair can be plugged into the plug-in column 201 on the top plate 102, and the motor 206 is started to reverse. The reversal of the motor 206 drives the four positioning columns 209 to move toward the periphery at the same time, so that the four positioning columns 209 are simultaneously inserted into the positioning grooves 2010 inside the plug-in grooves 202, thereby achieving rapid fixation of the installation plate 300 and the plug-in column 201, and thus achieving the purpose of rapid disassembly and installation of the lifting component 100 and the leisure chair.
