In the present embodiment, the first push rod 121 is provided with a sleeve 125 and a bearing 124 in this order in the X-axis direction near one end of the fourth gear 14 to cooperate with the push rod mechanism 12 to axially rotate in its own axis direction.
In a specific application scenario, the initial position of the second push rod 122 is located at the first station, the motor 11 is started, the output shaft 111 drives the third gear 13 to rotate, the third gear 13 is sequentially driven by the first gear 16, the second gear 17 and the fourth gear 14 and drives the first push rod 121 to rotate, it can be understood that when the first push rod 121 rotates, the first thread 1211 rotates to drive the second thread 1221 to rotate and further drive the second push rod 122 to axially move to the second station along the axial direction thereof, and the extension rod 123 fixed on the second push rod 122 also axially moves along the axial direction thereof along with the second push rod 122, so that the effect of pushing the door from the inner side of the door when the pushing device is installed on the inner side of the box door is achieved.

The first engagement portion 161 is disposed coaxially with the second engagement portion 162, and the radius of the second engagement portion 162 is smaller than the radius of the first engagement portion 161. The third engagement portion 171 is disposed coaxially with the fourth engagement portion 172, and the radius of the fourth engagement portion 172 is smaller than the radius of the third engagement portion 171.
Specifically, the third gear 13 is engaged with the first engagement portion 161, the second engagement portion 162 is engaged with the third engagement portion 171, and the fourth engagement portion 172 is engaged with the fourth gear 14. The third gear 13, the first engagement portion 161, the second engagement portion 162, the third engagement portion 171, the fourth engagement portion 172, the fourth gear 14, and the elastic mechanism 15 are disposed in this order along a first direction, which is opposite to the X-axis direction.
In other embodiments, the gear set may include a plurality of gears, and the size and engagement of each gear may be set according to the actual required gear ratio, which is not limited in this disclosure.
In other embodiments, the drive mechanism may be a linear drive mechanism or a rotary drive mechanism.
In other embodiments, the first and second actuators are negative pressure or magnetic suction mechanisms.
In this embodiment, the pushing device further includes a housing 18, a motor 11, a push rod mechanism 12, a third gear 13, a fourth gear 14, a gear set, and an elastic mechanism 15 all disposed inside the housing 18, where the push rod mechanism 12 extends partially outside the housing 18.
Specifically, the end of the extension rod 123 provided with the flexible member 1231 extends outside the housing 18 to abut against the inside of a cabinet door.
In this embodiment, a plurality of mounting holes 181 are further formed around the housing 18, and the mounting holes 181 are respectively disposed near two sides of the extension rod 123 and near two sides of the gear set, so as to facilitate mounting and fixing the push rod device of this embodiment. The noise reduction mechanism is further arranged on each mounting hole 181, and specifically comprises a rubber ring 182, wherein the rubber ring 182 is nested inside the mounting holes 181 so as to prevent noise generated during normal operation of the push rod device after installation and have a certain damping function.
In a specific application scenario, the output shaft 111 of the motor 11 drives the push rod mechanism 12 to move along the X-axis direction, and the displacement of the push rod mechanism 12 pushes a box door to open; after that, the motor 11 rotates the output shaft 111 in the reverse direction for a preset time to drive the push rod mechanism 12 to move in the reverse direction of the X axis, so that the push rod mechanism returns to the original position, and the case door is prevented from being unable to be closed.
In a specific application scenario, after the motor 11 drives the push rod mechanism 12 to move along the direction of the X axis and push a box door open, the motor 11 does not reversely drive the push rod mechanism 12 to return to the original position, at this time, the box door is forcibly closed manually, the push rod mechanism 12 receives force in the opposite direction of the X axis, and a series of transmissions enable the 111 motor shaft to be rotated under the action of external force, so that the push rod mechanism 12 moves in the opposite direction of the X axis, and the box door is normally closed.
It will be appreciated that the output shaft 111 of the motor 11 may be rotated in either a clockwise or counter-clockwise direction to drive the push rod mechanism 12 back and forth in the X-axis direction. When the push rod mechanism 12 does not normally return to the first station, the push rod mechanism 12 is subjected to the action of external force, and the push rod mechanism 12 can return to the first station by extruding the elastic mechanism 15, so that the box door is normally closed; at this time, the fourth gear 14 moves along with the push rod mechanism 12 in the opposite direction of the X-axis and is disengaged from the second gear 17, and since the fourth gear 14 is disengaged from the second gear 17, there is little self-locking force, preventing the motor 11 from being locked, and when the door of the case is opened again, the push rod mechanism 12 returns to the first station under the action of the elastic mechanism 15, and the second gear 17 and the fourth gear 14 return to the engaged state, thereby returning the pushing device to normal operation.
According to the embodiment, the elastic mechanism 15 is arranged at one end of the push rod mechanism 12, so that when accidents such as power failure and the like occur to the driving mechanism, the push rod mechanism 12 can still move along the X-axis direction without affecting the closing of the box door, the box door is opened, the operation of the pushing device can be restored to be normal, and the usability, safety and stability of the pushing device are improved.
It should be understood that the above embodiments are merely for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and implement the same according to the present utility model without limiting the scope of the present utility model. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
