[0028] Refer to the following Figure 1-Figure 11A support structure of a microwave baking tray according to some embodiments of the present application is described.

[0029] A support structure of a microwave baking tray comprises an upper support 1 and a lower support 2, wherein the upper support 1 and the lower support 2 are respectively mounted on an upper baking tray 3 and a lower baking tray 4 of the microwave baking tray, wherein one end of the upper support 1 and the lower support 2 are rotatably connected, and the other end is unfolded or locked to open or close the upper baking tray 3 and the lower baking tray 4 of the microwave baking tray.

[0030] The support structure also includes at least one limiting rotating shaft 5 and at least one protrusion 8, and the limiting rotating shaft 5 and the protrusion 8 are arranged in a one-to-one correspondence; wherein the limiting rotating shaft 5 includes a fixed end 6 and a free end 7, and the fixed end 6 of the limiting rotating shaft 5 is arranged on one of the upper bracket 1 and the lower bracket 2, and the corresponding protrusion 8 is arranged on the other of the upper bracket 1 and the lower bracket 2; a rotating shaft hole 9 is arranged on the protrusion 8, and the limiting rotating shaft 5 is inserted into the rotating shaft hole 9 and can rotate in the rotating shaft hole 9; a first limiting portion 10 is arranged on the fixed end 6 of the limiting rotating shaft 5; a second limiting portion 11 is arranged on the upper bracket 1 or the lower bracket 2 where the corresponding protrusion 8 is located, and the second limiting portion 11 is located on the insertion side of the rotating shaft hole 9 To one side, the first limiting portion 10 can be placed in the gap between the second limiting portion 11 and the protrusion 8; the avoidance groove 12 is arranged on the side of the first limiting portion 10 facing the second limiting portion 11; when the upper bracket 1 and the lower bracket 2 form a first angle range, that is, the installation connection angle of the upper bracket 1 and the lower bracket 2, within this first angle range, the second limiting portion 11 can pass through the avoidance groove 12 and make the limiting shaft 5 inserted into the shaft hole 9 to realize the connection between the upper bracket 1 and the lower bracket 2; within the second angle range outside the first angle range, since the end of the first limiting portion 10 conflicts with the end of the second limiting portion 11, the limiting shaft 5 cannot escape from the shaft hole 9, and the upper bracket 1 and the lower bracket 2 maintain a rotational connection.

[0031] In the first embodiment, the surface of the avoidance groove 12 is sloped, the entrance 13 of the avoidance groove 12 matches the outer edge of the second limiting portion 11, and the exit 14 of the avoidance groove 12 is smaller than the outer edge of the second limiting portion 11. Therefore, as the second limiting portion 11 enters the avoidance groove 12, the upper bracket 1 and the lower bracket 2 are gradually slightly elastically deformed, and the elastic deformation is reset after the second limiting portion 11 passes through the avoidance groove 12, and the second limiting portion 11 is blocked outside the exit 14 of the avoidance groove 12, so that the limiting rotating shaft 5 cannot be disengaged from the rotating shaft hole 9 within the first angle range. That is, after the upper bracket 1 and the lower bracket 2 are installed and connected, they can maintain a rotation connection within the entire rotation angle range.

[0032] In the second embodiment, a conical protrusion 15 is provided at the end of the second limit portion 11, and the height of the protrusion 15 is greater than the depth of the avoidance groove 12. As the second limit portion 11 enters the avoidance groove 12, it gradually causes slight elastic deformation of the upper bracket 1 and the lower bracket 2. After the second limit portion 11 passes through the avoidance groove 12, the elastic deformation is reset, and the second limit portion 11 is stopped outside the outlet 14 of the avoidance groove 12, so that the limit rotation shaft 5 cannot escape from the rotation shaft hole 9 within the first angle range. That is, after the upper bracket 1 and the lower bracket 2 are installed and connected, they can maintain a rotation connection within the entire rotation angle range.

[0033] In Example 3, the free end 7 of the limiting rotating shaft 5 is provided with an elastic limiting portion 16, the width of which is greater than the inner diameter of the rotating shaft hole 9, and when the second limiting portion 11 passes through the avoidance groove 12, the elastic limiting portion 16 is inserted into the rotating shaft hole 9 and deforms, and resets after the elastic limiting portion 16 extends out of the rotating shaft hole 9, and since the width of the elastic limiting portion 16 is greater than the inner diameter of the rotating shaft hole 9, the limiting rotating shaft 5 cannot escape from the rotating shaft hole 9. That is, after the upper bracket 1 and the lower bracket 2 are installed and connected, the rotation connection can be maintained within the entire rotation angle range.

[0034] The limiting rotating shaft 5 includes a clearance groove 17, which extends from the end surface of the free end 7 to the inside of the limiting rotating shaft 5, and the length of the clearance groove 17 extending from the end surface of the free end 7 to the inside of the limiting rotating shaft 5 is greater than the length of the elastic limiting portion 16. The clearance groove 17 can cooperate to complete the deformation and reset of the elastic limiting portion 16. The elastic limiting portion 16 can be an annular flange or a convex block provided on the free end 7.

[0035] In embodiments 1-3, there are two limit shafts 5 and two protrusions 8, which are respectively arranged on the upper bracket 1 and the lower bracket 2. Of course, according to the use requirements, one or more limit shafts 5 and protrusions 8 can be arranged, and the limit shafts 5 and protrusions 8 can be arranged in sequence or at intervals.

[0036] In this technical solution, the avoidance grooves and multiple limiting parts set on the upper and lower brackets work together to prevent the limiting shaft from falling out of the shaft hole during use, thereby ensuring the long-term stability of the microwave oven. When the upper and lower brackets need to be disassembled for maintenance or cleaning, it can only be completed by using a certain external force to release the constraints of the multiple limiting parts.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
