[0021] In order to better understand the purpose, structure and function of the utility model, the specific embodiments of the utility model "a kind of oven automatic door opening and closing mechanism" are further described in detail below in combination with the drawings.

[0022] Reference Figures 1-4In the embodiment, the automatic oven door opening and closing mechanism comprises a box body 100 and a door body 200. The box body 100 is provided with an opening 101. The door body 200 is hinged to the lower edge of the opening 101 so as to open and close the box body 100 by rotating the door body 200. A support frame 102 is arranged in the box body 100. A groove 103 perpendicular to the direction of the opening 101 is arranged on the support frame 102. A rack 104 is arranged in the groove 103. A sliding frame 105 is arranged on the support frame 102 and slides along the groove 103. A motor 106 is fixed to the sliding frame 105. A gear 107 engaged with the rack 104 is arranged on the groove 103. One end of the wheel shaft of the gear 107 is connected with the motor 106. The other end of the gear 107 is hinged to one end of a transmission rod 108. The other end of the transmission rod 108 is hinged to the door body 200. In use, the motor 106 drives the gear 107 to rotate. The gear 107 moves back and forth in the groove 103 along the rack 104. The sliding frame 105 carrying the motor 106 and the transmission rod 108 move back and forth along the groove 103. The transmission rod 108 drives the door body 200 to rotate to automatically open and close the box body 100. The mechanism can automatically open and close the oven door, saving time and effort, without the need for manual operation, and is safe.

[0023] It should be noted that, in the embodiment, in order to ensure the stability of the opening and closing of the door body 200, the automatic door opening and closing mechanisms are arranged on both sides of the box body to simultaneously apply a pushing force / pulling force to the door body 200 to open / close the door. The rack 104 and the groove 103 are detachably fixedly connected. When the precision of the mechanism needs to be adjusted, the rack 104 with different precision can be replaced, which is convenient for adjustment.
