fig. 2 is a structural schematic diagram of a second group of working states of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1, the utility model discloses a motor, middle part and motor rotation axis fixed connection's first gear 1 still include rack 2 and sector gear 4, wherein, the both sides of rack 2 are equipped with the meshing tooth respectively, and wherein one side meshes with first gear 1, and the opposite side meshes with sector gear 4.

The utility model discloses utilize the motor to drive 2 movements of rack, rack 2 drives the sector gear 4 rotation of major diameter again, and sector gear 4's marginal end is used by push-and-pull article 5 on, realizes the motion process of push-and-pull. The rack 2 is additionally used as a middle transmission part, because a complete gear is inconvenient to install in order to save space in an actual device, a pinion of a motor cannot directly drive a complete stroke, the stroke is conveniently controlled according to the length of the rack 2 after the rack 2 is used, redundant space cannot be occupied, and the push-pull device can be made to be proper in size. Of course, if the installation control is not limited, the transmission component arranged in the middle of the present example and the gear which can be 1 or more gears which are meshed with each other.

In the embodiment, the motor drives the rack 2 to move, the rack 2 drives the sector gear 4 with large diameter to rotate, and the edge end of the sector gear 4 acts on a pushed or pulled object to realize the pushing and pulling movement process.

The local gear combination electric push-pull mechanism of the embodiment can be widely applied to various electric revolving doors, such as electric doors of various cabinets, and the utility model can be applied to the electric doors which can be opened in the largest direction, and can be opened only half or occupy the side position unlike the transverse push-pull. Moreover, the push-pull device of the utility model has the acting force placed at the far end of the door rotating shaft 6, so that the force required by the rotation is minimum. Therefore, the utility model discloses will bring fine social energy saving and emission reduction's effect for the work efficiency of revolving door is higher, must bring the helping hand for new machine innovation.

In the embodiment, the pushing or pulling effect is realized by setting the meshing position of the rack 2 and the first gear 1, and the two setting modes are shown in fig. 1 and fig. 2. The gray arrow and the black arrow represent the action direction of the rack and the movement direction of the pushed and pulled object 5 relative to the device body 7 under the driving of the sector gear 4 when the rotation directions of the motors are different.

The rack 2 in this embodiment may be straight, or may have a certain curvature, or may be partially straight, or partially curved.

Preferably, the rack 2 of the embodiment is mounted on the slide rail 3, so that the rack 2 is meshed with the first gear 1 driven by the motor under pressure, the position of the motor is fixed, the rotating shaft of the motor can drive the first gear 1 to rotate in place, the rack 2 is driven to move when the first gear 1 rotates, the insection of the rack 2 is meshed with the sector gear 4 on the other side, the sector gear 4 is driven to rotate when the rack 2 moves, the sector gear 4 is mounted on the pushed and pulled object 5, and thus the pushed and pulled object can rotate along with the sector gear. The pushed object rotates back along with the sector gear 4 along with the forward rotation and the reverse rotation of the motor.

The sector gear 4 of this example can be made as large as the cross section of the object 5 to be pushed and pulled, so that the object can be rotated with a minimum force by applying the rotational pushing and pulling force to the distal end from the center of rotation (the rotation axis 6). In this embodiment, the rack 2 is mounted on the slide rail 3, so that the friction force can be reduced. Therefore, a relatively heavy object can be pushed and pulled with relatively little force. Preferably, in this embodiment, in-place detection switches are further disposed at both ends of the rack 2, so that the stroke of the motor can be conveniently controlled.

The above-mentioned embodiments are the preferred embodiments of the present invention, and the scope of the present invention is not limited to the above-mentioned embodiments, and the scope of the present invention includes and is not limited to the above-mentioned embodiments, and all equivalent changes made according to the present invention are within the protection scope of the present invention.
