Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of barbecue oven equipment, especially a lock catch for locking the upper cover and lower oven of a barbecue oven. BACKGROUND

[0002] Barbecue ovens originated in the United States. They are airtight containers that combine multiple cooking methods, such as baking, smoking, steaming, grilling, boiling, and stewing. They can cook steaks, turkeys, pizzas, and hamburgers. The features include thick walls, good airtightness, heat retention, fast heating, constant temperature, heat preservation, and temperature reflection. When cooking, the moisture of the food can be "locked in", preventing the food from drying out and improving the taste.

[0003] Chinese patent document with the authorization publication number CN211874201U discloses a lock catch for locking the upper cover and lower oven of a barbecue oven. It includes two fixed seats, each with two or more mounting holes. The fixed seats are divided into a first fixed seat and a second fixed seat. The first fixed seat has a barb. The second fixed seat has a clasp hinge in the middle. The clasp has a clamping end and a pressing end. The clamping end has a groove for inserting the barb hook. The second fixed seat has two lugs. The clamping end and the pressing end are connected by a hollow middle body. The middle body is bent towards the hook side of the barb at the pressing end. The middle body and the lugs are connected by a pin shaft. A V-shaped torsion spring is fitted on the pin shaft. The two legs of the V-shaped torsion spring are clamped between the second fixed seat and the middle body, separating the pressing end from the second fixed seat. The barbecue oven in the utility model has better sealing performance and is less likely to leak. The lock catch is easy to open and close.
