Description

Technical Field

[0001] This utility model relates to the field of door accessories technology, specifically to a small-sized variable speed controller for doors. Background Technology

[0002] Sliding doors and guide rail doors are popular in the market. These doors often use motors to achieve electric opening and closing. Many electric doors and windows use worm gears to drive the door. This worm gear transmission design can output relatively large transmission force, which is more suitable for heavy doors and windows. However, the transmission device of this design is often large in size. When installing doors and windows, the motor and transmission device will be exposed, or a hole needs to be dug in the wall to install the transmission device.

[0003] The large size of the aforementioned transmission devices and motors affects the consumer experience and product installation. Therefore, it is necessary to develop a small-sized regulator with high transmission power that can be stored in the track for easy installation. Utility Model Content

[0004] Therefore, this utility model provides a small-sized variable speed controller for doors to solve the problems caused by the large displacement due to the worm gear connection design.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small-sized variable speed controller for doors, comprising a base, one end of which is fixedly connected to a motor; a first transmission rod is designed at the end of the base near the motor; a second transmission rod is designed at the middle of the base; a third transmission rod is designed at the right side of the base; an output rod extends from the middle of the motor; and a transmission wheel corresponding to the output rod is designed on the first transmission rod.

[0006] The second transmission rod is designed with a second fine transmission tooth and a second large transmission tooth arranged side by side. The second large transmission tooth meshes with the transmission wheel and rotates synchronously with the second fine transmission tooth.

[0007] Below the third transmission rod is a third transmission gear that meshes with the second transmission fine gear, and above the third transmission gear are pulleys arranged side by side.

[0008] Preferably, the output rod and the surface of the transmission wheel are designed with oblique grooves for transmission, and the surface of the transmission wheel and the second transmission large tooth are designed with oblique grooves for transmission.

[0009] Preferably, the second transmission fine gear and the second transmission large gear are synchronously rotated, and the third transmission gear and the pulley are synchronously rotated.

[0010] Preferably, the number of teeth on the outer periphery of the second transmission large tooth is greater than that of the second transmission small tooth.

[0011] Preferably, the base is designed with multiple shock-absorbing rubber feet underneath.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the output rod and the transmission rod convert lateral power into longitudinal transmission, changing the transmission direction by 90 degrees. This effectively saves space. Furthermore, the transmission method involves adjusting the transmission speed to increase torque. The number of teeth on the outer periphery of the second transmission large gear is greater than that of the second transmission small gear, effectively converting speed into torque and providing power output. Finally, the second transmission fine gear and the third transmission gear further reduce the speed, thereby increasing the torque effect. Finally, the pulley drives the belt and pulls the door and window. Attached Figure Description

[0017] Example:

[0018] See attached document Figure 1-2 This utility model provides a small-sized variable speed controller for doors. The controller includes a base 1, with a motor 2 fixedly connected to one end. A first transmission rod 11 is designed at the end of the base 1 near the motor 2. A second transmission rod 12 is designed at the middle of the base 1. A third transmission rod 13 is designed at the right side of the base 1. An output rod 21 extends from the middle of the motor 2. A transmission wheel 111 corresponding to the output rod 21 is designed on the first transmission rod 11.

[0019] The second transmission rod 12 is designed with a second fine transmission tooth 121 and a second large transmission tooth 122 arranged side by side. The second large transmission tooth 122 is meshed with the transmission wheel 111. The second large transmission tooth 122 and the second fine transmission tooth 121 rotate synchronously.

[0020] Below the third transmission rod 13, a third transmission gear 131 is designed to cooperate with the second transmission fine gear 121, and above the third transmission gear 131, a pulley 132 is designed side by side.

[0021] Preferably, the output rod 21 and the transmission wheel 111 are designed with oblique grooves for transmission, and the transmission wheel 111 and the second transmission gear 122 are designed with oblique grooves for transmission.

[0022] Preferably, the second transmission fine tooth 121 and the second transmission large tooth 122 are synchronously rotated, and the third transmission gear 131 and the pulley 132 are synchronously rotated.

[0023] Preferably, the number of teeth on the outer periphery of the second transmission large tooth is greater than that of the second transmission small tooth.

[0024] Preferably, the base is designed with multiple shock-absorbing rubber feet 4.

[0025] In this invention, the output rod and the herringbone transmission rod convert lateral power into longitudinal transmission. This efficient transmission method provides a basis for subsequent adjustment and transmission of variable torque. The number of teeth on the outer periphery of the second transmission large tooth is greater than that of the second transmission small tooth, converting speed into torque and providing power output. Finally, the second transmission fine tooth and the third transmission gear further reduce the speed, thereby increasing the torque effect, and finally driving the pulley to pull the belt and the door / window.
