Abstract: The present invention relates to an internal fixing device for an apparatus in a transport mode, an apparatus comprising said device, and a method for reducing the risk of damage to the apparatus during transport. The internal fixing device comprises a limiting device, eccentric roller transmission assemblies, a motor assembly, a motion guide assembly, etc. The two ends of a motor output shaft are fixedly disposed on eccentric roller transmission assemblies on two sides of the apparatus. By triggering a microswitch on the limiting device, eccentric rollers and rocking handles form self locking in a transport mode to stop motion. The present invention can effectively reduce the risk of damage to the apparatus during transport.

Abstract: A quickly assembled and disassembled window frame structure is provided. The quickly assembled and disassembled window frame structure includes a sliding window frame, within which two pieces of movable glass are mounted. The sliding window frame is provided with a rail. The rail at an upper side of a movable glass defines a section of notch, through which the moveable glasses can be removed upwards. A trim strip for sealing the notch is detachably mounted in the notch. A cover plate is detachably mounted at an upper side of the trim strip. A latch is fixedly mounted on the sliding window frame. The latch is located at an upper side of the cover plate and is configured to fix the cover plate and the trim strip.
