Description

Technical Field

[0001] This utility model relates to the field of door opener technology, specifically to a door opener that automatically opens and locks. Background Technology

[0002] Large buildings typically have heavy and wide gates, usually operated electrically by gate openers, providing convenience to users. However, gate openers often experience malfunctions such as power outages, preventing the gate from rotating freely. Forcibly moving the gate can damage internal components, significantly reducing the gate's lifespan. To ensure the gate can still open and close normally in the event of a power outage or other malfunctions, opening mechanisms have been developed. In emergencies, the connection between the opening mechanism and the transmission device can be disconnected, allowing the gate to be moved manually. However, current opening mechanisms on the market are complex in structure, expensive to manufacture, prone to jamming, difficult to open, and ineffective. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide an automatic door opener with a simple structure and low manufacturing cost.

[0004] This utility model is achieved through the following technical solution:

[0005] An automatic opening and locking door opener includes a rotating shaft, a transmission gear mounted on one side of the rotating shaft, a roller mounted on the other side of the rotating shaft, the roller being rotatably connected to the rotating shaft, a lever mounted in the middle of the rotating shaft, the lever being slidably connected to the rotating shaft, an adjusting spring mounted on the other side of the rotating shaft to abut the lever, the roller having a connecting groove for the lever to connect to, and an adjusting screw on one side of the rotating shaft.

[0006] Furthermore, the paddle is connected to the rotating shaft via a positioning pin, and the paddle has an elongated opening for the positioning pin to slide through.

[0007] Furthermore, the outer side of the transmission gear is provided with teeth.

[0008] Furthermore, a self-locking buckle is installed on one side of the rotating shaft to abut against the transmission gear.

[0009] Furthermore, a positioning screw is installed on the other side of the rotating shaft to abut against the adjusting spring, and the positioning screw is provided with a positioning screw adjustment hole.

[0010] Furthermore, the adjusting screw is provided with an adjusting screw adjusting hole.

[0011] Furthermore, the paddle is provided with a sleeve for positioning and mounting the adjusting spring.

[0012] Furthermore, the inner side of the transmission gear is provided with a stop block for the paddle to abut against.

[0013] Furthermore, the rotating shaft is provided with a sliding groove for the paddle to slide in.

[0014] Furthermore, the transmission gear is used for transmission connection with the motor output device.

[0015] Compared to existing technologies, this invention features a lever installed in the middle of a rotating shaft, which is slidably connected to the shaft. An adjusting spring is installed on the other side of the shaft to hold the lever in place. A roller has a connecting groove for the lever, and an adjusting screw is located on one side of the shaft. In use, adjusting the adjusting screw holds the lever in place, allowing it to enter the connecting groove of the roller. The transmission gear drives the roller to rotate via the shaft and lever, achieving automatic opening, closing, and locking of the gate. In the event of a power outage or other malfunction, adjusting the adjusting screw causes the lever to be released from the connecting groove of the roller by the adjusting spring, allowing the roller to rotate freely. The gate can be moved manually and still open or close normally. Furthermore, the opening device has a simple structure, low manufacturing cost, no jamming, easy opening, low power consumption, and a safe and reliable locked state, resulting in excellent performance.
