Problems solved by technology

For the above-mentioned intelligent portable cleaning and ironing suitcase, the two threaded screw rods only play the role of lifting, and an additional track mechanism (ie, the upper guide rail of the inner box and the lower guide rail of the outer box) needs to be configured for the lifting movement of the cleaning mechanism. Increases cost and also takes up space inside the suitcase

Abstract

The invention provides screws, a lifting mechanism and a luggage case. Each screw comprises a screw main body part extending along the axial direction of the screw, wherein the screw main body part comprises an inner cavity, track parts symmetrically arranged at the periphery of the inner cavity, external threads arranged at the periphery of the track parts, and a sliding groove formed between thetwo adjacent track parts along the circumferential direction of the screw main body part. The track parts are matched with the sliding grooves. When the screws are used in the lifting mechanism, thetrack parts of one screw is matched with the sliding groove of the other screw so as to achieve sliding fit and meshing between the two screws, and the sliding fit of the two screws provides a risingand falling motion space for rising and falling of the lifting mechanism. After the two screws mesh with each other, tracks for the rising and falling motion of a lifting part in the lifting mechanismis provided, so that the lifting mechanism integrates the functions of rising, falling and the tracks, and the functions of the lifting mechanism are improved.

Description

technical field [0001] The invention relates to a screw. [0002] The present invention also relates to a lifting mechanism comprising the above-mentioned screw rod. [0003] The present invention further relates to a suitcase comprising the above-mentioned lifting mechanism. Background technique [0004] Some equipment will be equipped with lifting parts that move up and down, and the height of the equipment will change. It is necessary to wait for the height of the equipment to rise to a certain height before allowing the lifting parts to move up and down inside the equipment. For example: an intelligent portable cleaning and ironing suitcase disclosed in the Chinese invention patent application with the application number of 201910221256.8, which has an inner box, an outer box, a box lifting mechanism, a washing machine lifting mechanism, and a cleaning mechanism. The body and the outer box are connected through the box lifting mechanism, so that the inner box can move ...
