Description

Technical Field

[0001] This utility model relates to the field of air sintering furnace technology, specifically a box-type air sintering furnace. Background Technology

[0002] Air sintering furnaces typically consist of a box-type casing containing the furnace itself. A swingable door is usually installed to close the furnace. Currently, after closing, the door needs to be locked to the casing. This is generally achieved by a rotating wheel connected to a swinging threaded rod. After the threaded rod engages with a clip on the door, rotating the wheel secures it to the door. This process requires rotating at least four wheels to gradually lock the door to the casing, making it quite complex for operators. Extensive research has been conducted on this issue.
