In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1 , Figure 2 As shown, the first aspect of this embodiment provides a safety protection device for a clamshell oven, the clamshell oven comprises an upper cover 11 and a lower cover 12, the first side of the upper cover 11 and the first side of the lower cover 12 are hinged; the safety protection device is arranged on the second side of the upper cover 11, and the second side of the upper cover 11 is opposite to the first side of the upper cover 11. The safety protection device is used to self-lock the upper cover 11 when the upper cover 11 is unfolded to a set angle to avoid related safety hazards. Specifically, the safety protection device comprises a support rod 2 and a self-locking component.

[0025] The self-locking assembly includes a fixed plate, a limiting plate 32 and a latch 31. The fixed plate is connected to the second side of the upper cover body 11 by bolts, and the limiting plate 32 is welded to the fixed plate. The limiting plate 32 is arranged in parallel with the upper cover body 11 and extends in a direction away from the upper cover body 11. The limiting plate 32 is provided with a first through slot, the length direction of which is consistent with the extension direction of the limiting plate 32, and the first through slot is used to limit the rotation angle of the support rod 2; the latch 31 is connected to the fixed plate and inserted into the first through slot, dividing the first through slot into a first sub-through slot 3211 close to the upper cover body 11 and a second sub-through slot 3212 away from the upper cover body 11, and the axial direction of the latch 31 is perpendicular to the length direction of the first through slot.

[0026] The first end of the support rod 2 is hinged to the lower cover 12 through a connecting piece. Specifically, the connecting piece is connected to the lower cover 12 through a bolt. The connecting piece is provided with a second through slot. The first end of the support rod 2 is inserted into the second through slot and connected to the connecting piece through a rotating shaft. The support rod 2 passes through the second sub-through slot 3212. The second sub-through slot 3212 is used to limit the support rod 2. The second end of the support rod 2 is provided with a bayonet 21 that cooperates with the latch 31, that is, the second end of the support rod 2 is recessed inwardly toward one side of the upper cover 11 to form a recessed portion. The recessed portion extends toward the first end of the support rod 2 and forms a "U"-shaped bayonet 21.

[0027] The connecting member is also provided with a triangular support member, which is located at one end of the second through groove close to the lower cover body 12, and the triangular support member includes an inclined surface; the first cylinder 4 includes a first cylinder body and a first push rod, and the first cylinder body is located on the inclined surface and connected to the inclined surface, that is, the first cylinder 4 is connected to the lower cover body 12 through the connecting member, and the first cylinder 4 and the lower cover body 12 are arranged obliquely; the first push rod faces the support rod 2 and is used to push the support rod 2.

[0028] When the upper cover 11 is opened, the side of the support rod 2 close to the upper cover 11 sticks to the latch 31, and the support rod 2 will tilt toward the upper cover 11 under the limit of the first through groove until the upper cover 11 is unfolded to the set angle, that is, when the upper cover 11 is unfolded to the horizontal height corresponding to the first through groove and the bayonet 21, the support rod 2 will further tilt in the direction of the upper cover 11 due to its own gravity, and the latch 31 is stuck in the bayonet 21, and one side of the bayonet 21 is inserted into the first sub-slot 3211, so that the support rod 2 is stuck and limited by the latch 31. At this time, the support rod 2 cannot move, the support rod 2 supports the latch 31, and the upper cover 11 is fixed by the support rod 2; if the gas or power is cut off accidentally in the flip-top oven, the upper cover 11 will not close, thereby providing operation safety.

[0029] When the operation is completed and the upper cover 11 needs to be closed, the first cylinder 4 is started to push the support rod 2 to rotate in a direction away from the upper cover 11 until the support rod 2 is disengaged from the latch 31, and the upper cover 11 can be closed. In this embodiment, the inclination angle and specifications of the first cylinder 4 are adjusted, and when the first cylinder 4 reaches the maximum stroke, the support rod 2 is disengaged from the latch 31. At this time, the first push rod of the first cylinder 4 is controlled to be retracted, so that the support rod 2 can lock the upper cover 11 when the upper cover 11 is unfolded next time.

[0030] The second aspect of the present embodiment provides a clamshell oven, which includes an upper cover 11, a lower cover 12, a second cylinder 5, and a safety protection device. The first side of the upper cover 11 is hinged to the first side of the lower cover 12; the safety protection device is arranged on the second side of the upper cover 11, and the second side of the upper cover 11 is opposite to the first side of the upper cover 11; the safety protection device is as described in the first aspect of the present embodiment. The second cylinder 5 includes a second cylinder body and a second push rod, the second cylinder 5 is arranged next to the safety protection device, the second cylinder body is connected to the lower cover 12, and the end of the second push rod away from the second cylinder body is hinged to the upper cover 11; the second cylinder 5 is used to open or close the upper cover 11.

[0031] The flip-top oven is equipped with a safety protection device and has good safety performance.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
