[0023] The sliding support plate 103 moves up or down along the rectangular sliding cylinder 102, so as to realize the adjustment of the arc-shaped clamping groove plate 104. Until the arc-shaped clamping groove plate 104 moves to be opposite to the edge of the cover plate of the cooking device, then synchronously rotate each screw rod 105. When the screw rod 105 rotates, it drives the rectangular sliding cylinder 102 to close towards the center of the frame 100 along the dovetail chute 101 through the screw hole threadedly connected therewith, so that the arc-shaped clamping groove plate 104 gradually approaches the edge of the cover plate of the cooking device, effectively clamping and pressing the cover plate, thereby ensuring the sealing effect of the cover plate, and being able to flexibly adapt to cover plates of different thicknesses and sizes. The structure is simple and the use is convenient.

[0024] As Figures 2-3 shown, the adjusting mechanism includes a screw cylinder 106 respectively arranged on the top wall surface of the rectangular sliding cylinder 102. The screw cylinder 106 is cylindrical and has internal threads on its inner arc surface. Grooves corresponding to the screw cylinders 106 one by one are provided at the upper ends of the sliding support plates 103. A screw rod 107 is rotatably connected to the lower end of each sliding support plate 103. A second rotation hole for providing rotational support for the screw rod 107 is provided at the lower end of each sliding support plate 103. The screw rods 107 are respectively threadedly connected to the screw cylinders 106 located in one rectangular sliding cylinder 102.

[0025] Relevant operators rotate the screw rods 107 in sequence. Affected by the threaded relationship between the screw rods 107 and the screw cylinders 106, when the screw rods 107 rotate, they drive the sliding support plates 103 to move up or down along the rectangular sliding cylinders 102, so as to realize the adjustment of the arc-shaped clamping groove plates 104.

[0026] As Figures 1-4As shown, it further includes a synchronous drive assembly. The synchronous drive assembly is used to synchronously drive the rotation of the wire column 105. The synchronous drive assembly includes bevel gear one 200 respectively arranged at the end of the wire column 105 close to the axis of the frame 100. A rotating shaft 201 is rotatably connected to the axis of the inner cavity of the frame 100. A third rotating hole for providing rotational support for the rotating shaft 201 is provided at the axis of the inner cavity of the frame 100. One end of the rotating shaft 201 is provided with bevel gear two 202. Bevel gear one 200 is meshed and connected with bevel gear two 202 respectively.

[0027] The rotating shaft 201 and the bevel gear two 202 thereon rotate synchronously. When the bevel gear two 202 rotates, it transmits power through the bevel gear one 200 meshed with it, so as to rotate the wire column 105 and play a role in rapid transmission.

[0028] As Figures 1-4 shown, the synchronous drive assembly further includes a motor 203 arranged at the axis of the upper surface of the frame 100. The lower end of the output shaft of the motor 203 is fixedly connected to the upper end of the rotating shaft 201. The motor 203 is electrically connected to an external controller. Relevant operators control the operation of the motor 203 through the external controller. The output shaft of the motor drives the rotating shaft 201 and the bevel gear two 202 thereon to rotate synchronously, playing a role in rapid drive.

[0029] As Figures 1-2 shown, a plurality of mounting seats 300 are arranged at the lower end of the outer arc surface of the frame 100. The mounting seats 300 are evenly distributed in a ring shape. Relevant operators connect the frame 100 and its affiliated mechanisms to the cover of the cooking equipment by passing bolts through the mounting seats 300 and the corresponding screw holes on the cover.

[0030] As Figures 1-3 shown, the openings of the arc-shaped card slot plates 104 are all inclined outward from their vertical centers. Since the openings of the arc-shaped card slot plates 104 are inclined outward, when it contacts the connection between the cover and the cooking equipment and continues to move, it can strengthen the clamping force, effectively clamp and press the cover, thereby ensuring the sealing effect of the cover.

[0031] As Figures 1-3 shown, an avoidance opening adapted to each arc-shaped card slot plate 104 is provided at the lower end of the surface of the rectangular sliding cylinder 102 close to each arc-shaped card slot plate 104. The design of the avoidance opening provides a moving space for the arc-shaped card slot plate 104 to avoid interference.

[0032] The working principle of a pressing device for the cover plate of a cooking device provided by the present utility model is as follows: First, relevant operators fix the frame 100 and its attached mechanisms to the upper end center of the cover plate of the cooking device through the mounting base 300. Then, the relevant operators rotate the lead screw 107 in sequence. Affected by the threaded relationship between the lead screw 107 and the wire barrel 106, when the lead screw 107 rotates, it drives the sliding support plate 103 to move up or down along the rectangular sliding cylinder 102, so as to realize the adjustment of the arc-shaped clamping groove plate 104. Until the arc-shaped clamping groove plate 104 moves to be opposite to the edge of the cover plate of the cooking device, the relevant operators control the operation of the motor 203 through an external controller. The output shaft of the motor drives the rotating shaft 201 and the bevel gear two 202 on it to rotate synchronously. When the bevel gear two 202 rotates, it transmits power through the bevel gear one 200 meshed with it, so that each wire column 105 rotates synchronously. When the wire column 105 rotates, it drives the rectangular sliding cylinder 102 to close towards the center of the frame 100 through the threaded holes connected to it, so that the arc-shaped clamping groove plate 104 gradually approaches the edge of the cover plate of the cooking device. Since the opening of the arc-shaped clamping groove plate 104 is inclined outwards, when it contacts the connection between the cover plate and the cooking device and continues to move, it can strengthen the clamping force, effectively clamp and press the cover plate, thus ensuring the sealing effect of the cover plate, and can flexibly adapt to cover plates of different thicknesses and sizes. The design of the avoidance opening provides space for the arc-shaped clamping groove plate 104 to move and avoids interference.

[0033] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] The above is the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
