AI Technical Summary
The handles of existing insulated boxes are not securely connected to the box body and are prone to coming loose.
The first inner plug and the first outer plug, and the second inner plug and the second outer plug are connected by a joint. The pull rope passes through these plugs and is finally fixed in the second outer plug, which increases the contact area between the pull rope and the heat preservation device and ensures a stable connection.
This effectively prevents the handle from coming loose during use, improving the reliability of the connection between the handle and the insulated box and the stability of its use.
