Abstract
The utility model relates to a lifting hot pot stove, in particular to a lifting device for the lifting hot pot stove. The lifting ejector rod and the nut are arranged in the guide sleeve, a guide limiting mechanism is arranged between the nut and the guide sleeve, the motor drives the screw rod to rotate, the screw rod extends into the guide sleeve from the bottom end of the guide sleeve and penetrates through the nut, the screw rod is in threaded fit with the nut, and the top end and the bottom end of the guide sleeve are respectively provided with a limiting block for limiting the nut to move up and down. The utility model discloses cancel the spring, the nut rises to a certain position and is prevented by the spacing piece and can not up move again, and screw rod and motor can unable the rotation, and motor current can change, and the circuit board detects the electric current of motor and changes the back this moment, and stop motor work, it is this principle that the nut descends also to have the same reason. By adopting the lifting structure, the noise is reduced, the chafing dish stove does not shake, the structure is simple, and the cost is reduced.
Description
Technical Field
The utility model relates to a lifting hot pot stove, in particular to a lifting device for the lifting hot pot stove.
Background
The lifting device of the existing lifting hot pot stove comprises a motor, a guide sleeve, a screw rod, a nut and a lifting ejector rod, when the lifting ejector rod is lifted to the highest position, the nut is separated from the screw rod, the nut idles, the lifting ejector rod does not rise, if the lifting ejector rod is lowered, a spring is also arranged between the nut and the screw rod, and the spring can push the nut to be meshed with the screw rod downwards to enable the nut to be in threaded fit with the screw rod again. The structure is complex, and after the nut is separated from the screw rod, the nut idles and generates large noise and vibration with the spring.
Disclosure of Invention
Therefore, the utility model aims to provide a lifting device for lifting hot pot stoves, which saves cost, reduces noise and is reliable in lifting.
The purpose of the utility model is realized like this.
The utility model provides a lifting device that lift chafing dish stove was used, includes motor, uide bushing, screw rod, nut and lift ejector pin, uide bushing top and bottom trompil, lift ejector pin bottom is connected with the nut, and lift ejector pin and nut are all established in the uide bushing, are equipped with direction stop gear between nut and the uide bushing, motor drive screw rod is rotatory, and the screw rod stretches into the uide bushing and passes the nut from the uide bushing bottom, screw rod and nut screw-thread fit, and uide bushing top and bottom are equipped with the stopper that the restriction nut reciprocated respectively.
The technical scheme can be further perfected as follows.
The guiding and limiting mechanism comprises a guiding groove arranged on the outer surface of the nut, a guiding strip is arranged on the inner wall of the guiding sleeve along the axial direction, and the guiding groove is meshed with the guiding strip.
The utility model discloses cancel the spring, the nut rises to a certain position and is prevented by the spacing piece and can not up move again, and screw rod and motor can unable the rotation, and motor current can change, and the circuit board detects the electric current of motor and changes the back this moment, and stop motor work, it is this principle that the nut descends also to have the same reason. By adopting the lifting structure, the noise is reduced, the chafing dish stove does not shake, the structure is simple, and the cost is reduced.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The embodiment combines the attached drawing, a lifting device for lifting hot pot stove comprises a motor 1, a guide sleeve 2, a screw rod 3, a nut 4 and a lifting ejector rod 5, wherein holes are formed in the top end and the bottom end of the guide sleeve 2, the bottom end of the lifting ejector rod 5 is connected with the nut 4, the lifting ejector rod 5 and the nut 4 are both arranged in the guide sleeve 2, a guiding and limiting mechanism is arranged between the nut and the guide sleeve, the guiding and limiting mechanism comprises a guiding groove 6 arranged on the outer surface of the nut 4, a guiding strip 7 is arranged on the inner wall of the guide sleeve 2 along the axial direction, and the guiding groove 6 is meshed with the guiding strip 7. Of course, the outer surface of the nut is provided with the guide strip, the surface of the inner wall of the guide sleeve is provided with the guide groove along the axial direction, and the guide limiting function between the nut and the guide sleeve can also be realized.
The motor drives the screw rod to rotate, the screw rod extends into the guide sleeve from the bottom end of the guide sleeve and penetrates through the nut, the screw rod is in threaded fit with the nut, and the top end and the bottom end of the guide sleeve are respectively provided with limiting blocks 8 and 9 for limiting the nut to move up and down.
The motor drives the screw rod to rotate, the nut is in threaded fit with the screw rod, the nut rises along the screw rod, the lifting ejector rod rises together with the nut under the fit of the guide groove and the guide strip, when the nut rises and touches the limiting block 8, the nut stops rising, and the circuit board indicates the motor to stop working after detecting that the current of the motor changes. When the motor rotates reversely and the nut descends and touches the limiting block 9, the nut stops descending, and the circuit board detects that the current of the motor changes and then indicates the motor to stop working.
