DETAILED DESCRIPTION

[0018] like Figures 1 to 4As shown, a heating table lifting structure motor includes a motor fixing shell 10 and a driving motor 20, wherein the motor fixing shell 10 includes an upper shell 11 and a lower shell 12, the upper shell 11 and the lower shell 12 are relatively connected up and down, and the driving motor 20 is fixedly installed on the bottom of the lower shell 12 by fasteners, so that the driving motor 20 is installed on the motor fixing shell 10.

[0019] During the specific implementation, the upper shell 11 and the lower shell 12 are relatively recessed with mounting grooves 13, in which a driving rod 14 can be rotatably installed, and one end of the mounting groove 13 is recessed with a transmission slot 131, and one end of the driving rod 14 is provided with a transmission tooth 141 on the outer side, the size of the transmission slot 131 is larger than the size of the transmission tooth 141, and the transmission tooth 141 can be rotatably set in the transmission slot 131.

[0020] In a specific implementation, the drive motor 20 is provided with a motor shaft 21 in the middle of one end facing the motor fixed shell 10, and a worm sleeve 22 is fixedly sleeved on the outside of the motor shaft 21, and a transmission slot 132 is opened on one side of the transmission slot 131. The size of the transmission slot 132 is larger than the size of the worm sleeve 22, and the worm sleeve 22 is inserted into the transmission slot 132. At the same time, the worm sleeve 22 is meshed and connected with the transmission rotating gear 141. When in use, through the connection mode in which the worm sleeve 22 is fixedly sleeved on the outside of the motor shaft 21, the diameter of the motor shaft 21 can be made smaller, so that the overall volume of the drive motor 20 can be made smaller, thereby saving material costs.

[0021] During specific implementation, the worm sleeve 22 is sleeved on the outside of the motor shaft 21 and fixedly connected by interference fit. The size of the worm sleeve 22 is slightly larger than the size of the motor shaft 21. When the worm sleeve 22 is sleeved on the outside of the motor shaft 21, a certain pressure is generated. This pressure can ensure that the worm sleeve 22 is tightly fixed on the motor shaft 21 without loosening or falling off.

[0022] The driving motor 20 is provided with a plurality of fixing grooves 23 on one end surface facing the motor fixing shell 10, and a plurality of fixing holes 121 are provided on the surface of the lower shell 12. The fixing holes 121 correspond to the fixing grooves 23 one by one, and fasteners are passed through the fixing holes 121 to connect and fix to the fixing grooves 23, so that the driving motor 20 is fixedly installed on the motor fixing shell 10, which is convenient for installation.

[0023] The front and rear ends of the transmission slot 131 are symmetrically recessed with stabilizing grooves 133, and both of the stabilizing grooves 133 are provided with annular reinforcing ring sleeves 15. The two reinforcing ring sleeves 15 are respectively sleeved on both sides of the transmission tooth 141 of the driving rotating rod 14. This design can ensure that the driving rotating rod 14 has stable support around it when rotating, preventing excessive vibration or deviation during movement, so that the driving rotating rod 14 can be more stable when rotating, reducing the problems caused by the instability of the transmission device, and improving the reliability and stability of the entire system.

[0024] The edge of the upper shell 11 is recessed with a plurality of mounting through holes 111, and the edge of the lower shell 12 is opened with a plurality of mounting through grooves 122. The plurality of mounting through holes 111 and the plurality of mounting through grooves 122 correspond to each other one by one, and fasteners are passed through the mounting through holes 111 and connected and fixed to the mounting through grooves 122, so that the upper shell 11 and the lower shell 12 are fixedly connected, and the installation is simple and convenient.

[0025] To sum up the above, the driving motor 20 is installed on the motor fixing shell 10, and the middle part of one end of the driving motor 20 facing the motor fixing shell 10 is provided with a motor shaft 21, and the outer fixed sleeve of the motor shaft 21 is provided with a worm sleeve 22, and the worm sleeve 22 and the motor shaft 21 are fixedly connected by interference fit. Since the worm sleeve and the motor shaft are not integrated in the heating table lifting structure motor of the utility model, the diameter of the motor shaft is smaller, so that the overall volume of the driving motor can be smaller, thereby saving material costs.
