As shown in fig. 1 to 8, the frying and roasting machine includes an upper roasting tray assembly 10, a lower roasting tray assembly 20, a lifting rod 30, a stop 50, a locking member 62 and a rail 32 slidably engaged with the stop 50, wherein the lower roasting tray assembly 20 has a base 21, the upper roasting tray assembly 10 is pivotally connected to the lifting rod 30, and an end of the lifting rod 30 is pivotally connected to the base 21 through a rotating shaft 40; a stopper 50 is provided on an end of the base 21 or the lift lever 30; the rail 32 is arranged on the end of the lifting rod 30 or the base 21, and the stop piece 50 can slide relative to the rail 32 when the lifting rod 30 rotates around the rotating shaft 40; the locking member 62 is movable in the radial direction of the rotating shaft 40, and when the locking member 62 moves in the radial direction of the rotating shaft 40 into the track 32, the stopper 50 stops sliding until the locking member 62 stops, and when the locking member 62 moves in the radial direction of the rotating shaft 40 away from the track 32, the stopper 50 can freely slide along the track 32.

When the upper roasting tray assembly 10 is opened, the lifting rod 30 is only lifted, the lifting rod 30 drives the upper roasting tray assembly 10 to open the cover, and after the locking piece 62 extending into the track 32 contacts the stop piece 50, the positions of the upper roasting tray assembly 10 and the lower roasting tray assembly 20 are locked; when the locking member 62 is withdrawn from the track 32 and disengaged from the stop member 50, the stop member 50 can slide freely relative to the track 32, so that the upper grill pan assembly 10 can rotate freely relative to the lower grill pan assembly 20 to unlock, and the upper grill pan assembly 10 can be switched between the closed and open positions.

In the embodiment of fig. 2, there are two lifting rods 30, and the two lifting rods 30 are respectively disposed at two sides of the upper grill plate assembly 10. The grill further includes a handle 70 that connects the two lifting bars 30.

In this embodiment, there are two bases 21, and the two bases 21 and the two lifting rods 30 are respectively connected through different rotating shafts 40. In order to ensure ease of adjustment, the stop 50 may be provided on the base 21 on only one side. The other side only ensures a pivotal connection.

When the lifting rod 30 is connected to the upper tray assembly 10, the lifting rod 30 has a connecting shaft 33, the connecting shaft 33 is connected to the upper tray assembly 10, and the connecting shaft 33 is located between two ends of the lifting rod 30. Alternatively, the connecting shaft 33 is inserted into the connecting hole of the upper grill pan assembly 10.

In the embodiment shown in fig. 2, the frying and roasting machine further includes a pivot shaft 11, the connecting shaft 33 has a through hole, the connecting shaft 33 is also inserted into the connecting hole of the upper roasting tray assembly 10, and the pivot shaft 11 is inserted into the through hole of the connecting shaft 33 to connect the lifting rod 30 with the upper roasting tray assembly 10. In this way, a secure connection of the lifting rod 30 to the upper tray assembly 10 can be ensured.

As shown in fig. 2, the rotation shaft 40 is fixed to the lifting rod 30 by a fastening member 41. Thus, the lifting lever 30 is fixed to the rotation shaft 40 so that the rotation shaft 40 can rotate with respect to the base 21. Alternatively, the fastener 41 may be a screw.

As shown in fig. 2 and 3, the frying and roasting machine further includes an elastic returning member 63, a first end of the elastic returning member 63 is fixed to the lifting rod 30 or the base 21, a second end of the elastic returning member 63 abuts against the locking member 62, and the elastic returning member 63 provides a returning force to the locking member 62, which extends into the track 32. Optionally, the resilient return 63 is a spring. By providing the elastic reset member 63, the lock member 62 can be reset without an external urging force. And the elastic restoring member 63 provides a pushing force to the side of the rotating shaft 40 such that the locking end of the locking member 62 protrudes into the rail 32 to allow the locking member 62 to be stopped by the stopper 50.

In the embodiment shown in fig. 2 and 3, and 4 to 8, the stop 50 is an arc-shaped positioning protrusion, the locking end of the locking member 62 extends into the rail 32 and abuts against the end surface of the arc-shaped positioning protrusion to stop the position, and the end surface of the arc-shaped positioning protrusion serves as the locking position 51. Referring specifically to fig. 5 and 6, it can be seen that the end surfaces of the arc-shaped positioning protrusions can be stopped by the locking members 62, so that the upper grill pan assembly 10 and the lower grill pan assembly 20 are positioned.

Specifically, the lift lever 30 has a slide groove 31. In order to improve the operation convenience of the locking member 62, the frying and roasting machine further comprises a push button 61, and the push button 61 is slidably disposed at the sliding groove 31 and connected with the locking member 62. When the user toggles the push button 61, the push button 61 drives the locking member 62 to move towards the side far away from the rotating shaft 40, the locking member 62 is unlocked from the arc-shaped positioning protrusion, and at this time, the locking member 62 is separated from the end face of the arc-shaped positioning protrusion. Then, as shown in fig. 7 and 8, the opening of the lid is continued, and the locking member 62 slides along the outer peripheral surface of the arc-shaped positioning protrusion, so that the upper grill pan assembly 10 can be opened by 180 degrees.

Specifically, the locking member 62 includes a locking section 621 and a guiding section 622, and one end of the elastic restoring member 63 is sleeved on the guiding section 622. In this way, the guide section 622 can ensure the movement reliability of the elastic restoring member 63, and avoid the elastic restoring member 63 from being out of order due to displacement.

In order to improve the installation stability of the elastic restoring member 63, the lifting rod 30 is further provided with a guide cylinder 35, and at least a part of the elastic restoring member 63 is located in the guide cylinder 35. In this way, the guide cylinder 35 further fixes the elastic resetting member 63, so as to prevent the elastic resetting member 63 from being displaced due to stress, and ensure the compression and resetting reliability thereof.

As shown in fig. 3, the rail 32 is disposed at an end portion of the lifting rod 30, the stopper 50 is disposed on the base 21, an opening adapted to pass the locking member 62 is disposed on a wall of the rail 32, two guide ribs 34 are further disposed at the opening, the two guide ribs 34 are spaced apart to form a guide groove therebetween, and the locking member 62 moves along an extending direction of the guide groove. In this way, the direction of movement of the locking member 62 is effectively planned, improving the reliability of the movement of the locking member 62.

As shown in fig. 3, 6 and 8, the rail 32 is an arc-shaped groove, the arc-shaped positioning lug is embedded in the rail 32, when the lifting rod 30 swings, the arc-shaped positioning lug slides relative to the rail 32, and the groove end surface of the rail 32 is matched with the end surface stop of the arc-shaped positioning lug to limit the limit opening position. Because the rail 32 is disposed on the lifting rod 30 and the lifting rod 30 can swing, when the lifting rod 30 swings, the rail 32 is driven to rotate, and at this time, the arc-shaped positioning protrusion and the rail 32 move relatively. When the end of the rail 32 contacts the end face of the arc-shaped positioning protrusion, the upper grill pan assembly 10 cannot move any more, and the upper grill pan assembly 10 and the lower grill pan assembly 20 are positioned.

In the embodiment shown in fig. 7 and 8, when the arc-shaped positioning protrusions are stopped by the groove end faces of the rails 32, the upper grate plate assembly 10 is opened up to 180 degrees relative to the lower grate plate assembly 20.

Optionally, the angle between the locking position 51 of the arc-shaped positioning lug and the horizontal plane in the counterclockwise direction is 100 to 110 degrees. By changing the angle between the locking position 51 relative to the horizontal, the angle of positioning of the upper grate assembly 10 can be changed.

Further optionally, the angle between the locking position 51 of the arc-shaped positioning lug and the horizontal plane in the counterclockwise direction is 105 degrees. That is, in this embodiment, the upper grill pan assembly 10 can be locked in position when opened 105 degrees or 180 degrees.

when the cover opening operation of the grill machine shown in fig. 8 is performed, the user can lock and unlock the position of the upper grill plate assembly 10 by controlling the push button 61 moving on the lifting rod 30.

When the cover is opened, the push button 61 on the lifting rod 30 is pushed upwards, the upper baking tray assembly 10 is not blocked at about 105 degrees, and the 180-degree turnover can be realized; the push button is reset again through the action of the elastic reset piece 63 after the cover is closed by less than 105 degrees. When the cover is opened, if the push button 61 on the lifting rod 30 is not pulled, the locking piece 62 is blocked by the stop of the arc-shaped positioning lug when the cover is opened by 105 degrees, and the 105-degree turnover positioning is realized. That is, the frying and roasting machine of the present invention can realize the positioning of 105 degrees and 180 degrees, the locking piece 62 is matched with the stop piece 50 by the rotation of the lifting rod 30, the clamping and fixing of the upper roasting tray assembly 10 at 105 degrees is realized, and after the locking piece 62 is withdrawn from the locking position 51, the movement interference is removed, so that the upper roasting tray assembly 10 can be unfolded to 180 degrees.

example two

the difference from the first embodiment is that the elastic restoring member 63 is not provided.

In this embodiment, the position of the locking member 62 is controlled only by changing the position of the push button 61 to achieve locking or unlocking between the locking member 62 and the locking position 51. When the push button 61 is pushed to the position toward one side of the rotating shaft 40, the locking piece 62 is in a position easy to stop with the arc-shaped positioning bump; when the push button 61 is pushed to the position away from the rotating shaft 40, the locking member 62 is withdrawn from the space of the track 32, so that no matter how to adjust the opening angle of the upper grill plate assembly 10, the clamping positioning will occur.
