Detailed Implementation

[0022] like Figures 1 to 4 As shown, this utility model relates to an oven door locking structure, which includes a mounting bracket 1, a fastening assembly, a drive motor 2, a drive component 3, and a micro switch 15. The fastening assembly, drive motor 2, and micro switch 15 are all mounted on the mounting bracket 1. The drive motor 2 is connected to the drive component 3, with one end of the drive component 3 abutting against the fastening assembly. The drive motor 2 drives the drive component 3 to rotate, thereby rotating the fastening assembly. The fastening assembly fastens the oven door, opening and closing it. The other end of the drive component 3 is connected to the micro switch 15. The open and closed state of the fastening assembly is confirmed by whether the drive component 3 abuts against the micro switch 15. The fastening assembly fastens the oven door, closing it and preventing wear after prolonged use, thus solving the problem of incomplete oven door closure. Simultaneously, the drive motor 2 drives the drive component 3 to rotate, achieving the fastening function and automatically unlocking the oven door. The structure is simple and practical.

[0023] The fastening assembly includes a snap-fit ​​component 4 and a spring 9. The mounting bracket 1 has a hinge seat 5. One end of the snap-fit ​​component 4 is hinged to the hinge seat 5, allowing the snap-fit ​​component 4 to rotate around the hinge seat 5. The mounting bracket 1 has a limiting groove 6 through which the snap-fit ​​component 4 passes. One end of the snap-fit ​​component 4 passing through the limiting groove 6 has a snap-fit ​​part 7, which engages with the oven door to open and close the oven door. The mounting bracket 1 has a connecting folding plate 10 with a limiting notch 11. The snap-fit ​​component 4 has an abutment part 8 with a limiting hole 12. Both ends of the spring 9 are respectively installed in the limiting notch 11 and the limiting hole 12. The driving component 3 presses against the abutment part 8, thereby rotating the snap-fit ​​component 4, thus engaging the oven door.

[0024] The driving component 3 includes a cam 13 and a roller 14. The roller 14 is connected to the cam 13 and rotates synchronously with the cam 13. The driving motor 2 is connected to the cam 13 and drives the cam 13 and the roller 14 to rotate. When the cam 13 is rotating, one end of the cam 13 presses against the abutting part 8, thereby driving the snap-fit ​​part 4 to rotate. The roller 14 is provided with a pressing surface 16, which abuts against the micro switch 15.

[0025] Mounting bracket 1 is provided with mounting plate 17, mounting plate 17 is provided with mounting hole 18, and drive motor 2 is mounted on mounting plate 17 and fixed by bolts through mounting hole 18.

[0026] In use, the cam 13 is driven to rotate by the drive motor 2. During the rotation, one end of the cam 13 gradually presses against the abutment part 8 of the latching member 4, causing the latching member 4 to rotate until it separates from the oven door, thus allowing the oven door to be opened. At this time, the abutment surface 16 of the roller 14 separates from the micro switch 15. The micro switch 15 confirms that the locking structure is in the unlocked state. When the drive motor 2 drives the cam 13 to continue rotating, the cam 13 gradually separates from the abutment part 8. During the separation process, the elastic force of the spring 9 pulls the latching member 4 to rotate back to its original position, causing the latching member 4 to lock the oven door, thus locking the oven door. At this time, the abutment surface 16 of the roller 14 abuts against the micro switch 15, and the micro switch 15 confirms that the locking structure is in the locked state.
