The positioning end of the mounting bracket is installed at the upper end of the swing arm, the connecting end of the mounting bracket is installed with a mounting shaft, the mounting shaft is movably connected to the middle of the swing arm, and the two elastic ends of the elastic member are respectively pressed and connected to the swing arm and the mounting shaft. Under the elastic action of the elastic member, the mounting bracket always applies a downward force to make the swing arm always buckled on the door panel.

[0006] Optimized according to the above, a limiting cavity for the up and down movement of the mounting shaft is provided at the connecting end of the swing arm, and the elastic member is installed in the limiting cavity and its two elastic ends are respectively pressed and connected to the inner wall of the limiting cavity and the outer edge of the mounting shaft.

[0007] According to the above optimization, the mounting bracket is set to an "n"-shaped mounting bracket, the upper end of the "n"-shaped mounting bracket is covered and connected to the upper end of the swing arm, the two side portions of the "n"-shaped mounting bracket are respectively connected to the two sides of the swing arm and cover the ports on both sides of the limiting cavity, the mounting shaft passes through the limiting cavity and its two ends are respectively fixedly connected to the two side portions of the "n"-shaped mounting bracket.

[0008] According to the above optimization, the upper end of the swing arm is provided with a connection clamping position for covering and connecting with the upper end of the adapter mounting bracket.

[0009] According to the above optimization, a connecting platform is provided at the upper end of the swing arm, and a lower snap-in is provided at the outer edge of the connecting end of the swing arm. The connecting platform and the lower snap-in form a limiting snap-in portion that is snapped onto the door panel.

[0010] The advantages of the utility model are:

[0011] By adding an elastic locking device, with the structural cooperation of the mounting bracket and the elastic part of the elastic locking device, when the number of times the door is opened and closed increases, the door panel becomes thinner under the force, or when the box is turned upside down during transportation, the mounting bracket will continue to apply force downward under the elastic action of the elastic part, so that the swing arm can always be tightly fastened to the door panel, with a strong locking force, which effectively prevents the hinge from separating from the door panel, improves the structural stability, and ensures the use effect of the oven.
