DETAILED DESCRIPTION

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0044] like Figure 1 、 Figure 2 As shown, a specific embodiment of the present invention discloses a support structure, including a motor 410 and a screw rod 420; the screw rod 420 is supported by a rotation of a bearing seat 430; the screw rod 420 is provided with two threaded sections with opposite spiral directions, and a sliding sleeve 440 is sleeved on the threaded section, and a push block 450 is installed on the top surface of the sliding sleeve 440; the push block 450 is rotatably connected to a support plate 460 on one side close to the center of the screw rod 420, and the ends of the two support plates 460 are movably connected by a support plate 470; the screw rod 420 is driven by the motor 410, driving the two sliding sleeves to move, thereby driving the support plate to rise and fall.

[0045] The above structural design can realize deformation adjustment through the cooperation of the motor, the screw rod and multiple movable connected plates. When the two sleeves move toward each other, the support plate in the middle position is steadily arched and lifted, which can play an effective supporting effect; and when the two sleeves move in the opposite direction to the end, the multiple plates can be restored to a straight state, which will not occupy too much external space and is convenient for the overall layout setting; and the screw rod structure is adopted, which can perform more accurate displacement adjustment and more accurate height adjustment on the one hand; on the other hand, it can have a certain self-locking effect, will not shift easily, and provide stable support.

[0046] Further, if Figure 2 As shown, a convex block 461 is fixedly provided at the middle of both ends of the support plate 460, and both ends of the support plate 460 and the end of the block 461 are convex arc-shaped structures; the end surface of the push block 450 close to the support plate 460 is a convex arc-shaped structure, and a first slot 451 is provided in the middle position; the first slot is an arc-shaped concave structure, which is adapted to the shape of the block 461; both end surfaces of the support plate 470 are convex arc-shaped structures, and a second slot 471 is provided in the middle position; the second slot is an arc-shaped concave structure, which is adapted to the shape of the block 461 The shape is adapted; holes for installing pins are provided through the card block, the first card slot and the second card slot; the card blocks at both ends of the support plate are respectively clamped in the first card slot and the second card slot, and are rotatably connected by the pins passing through the holes, and the connected ends slide against each other; this structural design allows the push plate, the support plate and the supporting plate to be movably connected and coordinated, and to slide against each other at the connection parts, reducing the gap, reducing heat loss and waste, and preventing debris from splashing onto the screw rod when baking food, thereby maintaining the cleanliness and normal operation of the screw rod.

[0047] like Figures 3 to 6 As shown, the present invention further discloses an oven, comprising a housing 100, a door 200, a baking tray 300, and the aforementioned support structure 400; the bottom of the door 200 is rotatably connected to the bottom of the open opening of the housing 100; the support structure 400 is mounted on one side of the inner wall of the door 200; when the door 200 is opened to a horizontal position, the starter motor 410 can be adjusted to move the support plate 470 to a desired height position, so as to support the baking tray 300 moved to the outside;

[0048] The oven door of the above-mentioned oven adopts a downward-flipping opening action. When the oven door is swung to the horizontal position, it no longer moves and can serve as a support base. The supporting structure is installed on the oven door. When the support plate is raised to the required height, it can support one side of the baking tray moved out to the outside, so that the baking tray is in a relatively stable suspended position, without having to be completely moved to the outside, and both hands are freed for operation, thereby improving overall efficiency and operational safety.
