Description

Technical Field

[0001] This utility model relates to the field of barbecue grill technology, and in particular to a portable folding barbecue grill. Background Technology

[0002] With the increasing popularity of outdoor activities, portable grills have become widely popular due to their lightweight and ease of use. However, some lightweight folding grills have certain safety hazards in their structural design, especially in outdoor environments where they are often easily blown over or tipped over due to strong winds or uneven ground, posing a significant risk of use.

[0003] Chinese invention patent CN106308562B discloses a portable oven, including a base frame with a storage cavity inside, and a guide rail inside the storage cavity; an oven body including two baking trays, which are respectively located on both sides of the guide rail and can move along the height direction of the guide rail; one baking tray has a first through hole and the other baking tray has a second through hole; when the two baking trays rotate in a direction away from each other, the first through hole and the second through hole overlap and communicate; the bottom end of the baking tray has a first limiting part; and a locking component. The locking assembly is mounted on the base frame and includes an elastic component and a locking pin.
