[0021] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0022] Embodiment 1:

[0023] The present application provides an electric door opening device, comprising a door frame 1; a door leaf 2 is rotatably mounted inside the door frame 1, a door opening mechanism 3 is mounted on the inner top of the door frame 1, a connecting mechanism 6 is mounted on the bottom of the door opening mechanism 3, and a connecting rod 4 is mounted between the bottom of the connecting mechanism 6 and the door leaf 2;

[0024] The connection mechanism 6 includes a connection plate 601, a telescopic rod 602 and a fixed plate 603. The connection plate 601 is installed at the bottom of the door opening mechanism 3, the telescopic rod 602 is installed at the top of the connection plate 601, and the fixed plate 603 is installed at the top of the telescopic rod 602;

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a door opening mechanism 3 is installed on the inner top of the door frame 1, and the door opening mechanism 3 is connected to the door leaf 2 through a connecting mechanism 6 and a connecting rod 4. The door opening mechanism 3 works to drive the door leaf 2 to move via the connecting mechanism 6 and the connecting rod 4, so that the door can be opened and closed automatically. The connecting mechanism 6 is used to connect the door opening mechanism 3 and the connecting rod 4. The top of the fixed plate 603 is a rectangular protrusion, and a groove corresponding to the rectangular protrusion is provided at the bottom of the door opening mechanism 3. When the door opening mechanism 3 fails, the telescopic rod 602 on the top of the connecting plate 601 works, and the telescopic end of the telescopic rod 602 drives the fixed plate 603 to move. When the top of the fixed plate 603 is moved out from the inside of the door opening mechanism 3, the person can directly push the door leaf 2 to open and close the door, thereby avoiding affecting the movement of the door leaf 2 when the door opening mechanism 3 fails.

[0026] Further, a rotation sensor 7 is installed at the central position of the top of the connection disk 601;

[0027] Specifically, Figure 4 As shown, in order to monitor the working status of the door opening mechanism 3, the rotation sensor 7 can be used to observe whether the connecting disk 601 is rotating, so as to avoid the worker being unable to know the internal working conditions of the door opening mechanism 3 when the door opening mechanism 3 is working normally or malfunctioning. When the door opening mechanism 3 is working and rotating, and the connecting disk 601 does not rotate, it indicates that there is a fault at the transmission position, which makes it convenient for the worker to perform maintenance in time.

[0028] Further, the door opening mechanism 3 includes a motor 301, a coupling 302, a pinion 303, a large gear 304 and a fixed seat 305. The fixed seat 305 is installed on the inner top of the door frame 1, the motor 301 is installed on the top of the fixed seat 305, the coupling 302 is installed on the output end of the motor 301, the pinion 303 is installed on the bottom end of the coupling 302, and the large gear 304 is installed on one side of the pinion 303;

[0029] Specifically, Figure 3 As shown, in order to realize the opening and closing of the door leaf 2, the fixing seat 305 is used to fix the motor 301, and the output end of the motor 301 is connected to the small gear 303 through the coupling 302. The small gear 303 and the large gear 304 are gear-transmitted. The bottom of the large gear 304 is connected to the door leaf 2 through the connecting mechanism 6 and the connecting rod 4. The small gear 303 drives the large gear 304 to increase the torque, and then drives the door leaf 2 to open and close through the connecting rod 4, thereby realizing automatic opening and closing of the door.

[0030] Further, a contact structure 5 is installed on the top of the door leaf 2;

[0031] Specifically, Figure 2 As shown, in order to monitor whether the door leaf 2 is fully closed, a contact structure 5 is arranged on one side of the top of the door leaf 2. When the connecting rod 4 drives the door leaf 2 to open and close under the movement of the door opening mechanism 3, the contact structure 5 can be used to monitor whether the door leaf 2 is fully closed.

[0032] Furthermore, a storage plate 8 is installed on one side of the door frame 1 near the door opening mechanism 3, and a sponge 801 is installed on one side of the storage plate 8 near the door opening mechanism 3;

[0033] Specifically, Figure 3 As shown, in order to achieve better transmission between the small gear 303 and the large gear 304, lubricating oil is stored inside the storage plate 8, and the sponge 801 is in contact with the outer side of the small gear 303. The lubricating oil is directly applied to the outer side of the small gear 303 through the sponge 801, thereby enabling better transmission between the small gear 303 and the large gear 304.

[0034] Working principle: The motor 301 drives the small gear 303 to rotate through the coupling 302, and the small gear 303 and the large gear 304 are gear-transmitted. The bottom of the large gear 304 drives the door leaf 2 to open and close through the connecting rod 4, thereby realizing automatic opening and closing of the door.

[0035] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
