Abstract: A packaging tube is disclosed, which includes a cartridge core and a base; the cartridge core and the base are both made of metal materials, the cartridge core has an axial direction in space, the cartridge core comprises a bead, a fork and a spiral in sequence from inside to outside; the inner wall of the spiral is provided with a thread structure, when the spiral rotates relative to the fork, the thread structure drives the bead to slide in the axial direction relative to the fork, an adaptation structure capable of being inserted and pulled in the axial direction is provided between the fork and the base, and the adaptation structure limits the relative movement of the fork and the base in the axial direction and in a circumferential direction.

Abstract: A center tube core and a cosmetic packaging tube that contains the center tube core are provided. The center tube core comprises a prong, a spiral rotatably sleeved on the prong, and a bead slidably mounted in the prong so as to carry a product. The side wall of the prong is provided with a slide slot that extends axially, the outer wall of the bead is provided with a slide block that extends radially out from the slide slot, and the inner wall of the spiral is provided with a feeding thread that acts on the slide block. The prong, the bead and the spiral are all made using a metal material.

Abstract: A lipstick tube cartridge core comprising a ball (1), a fork (2), a spiral (3), and a cartridge (4). The spiral (3) and the cartridge (4) are provided therebetween with a keyway structure (33 and 43) arranged in the axial direction and an engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction. As the spiral (3) and the cartridge (4) are provided therebetween with the keyway structure (33) arranged in the axial direction and the engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction, retention of the spiral (3) and of the cartridge (4) is implemented without using a glue, thus preventing a scenario in which a cosmetic paste is contaminated by the glue.

Abstract: An easily dismantled escalator outer decking, the escalator including a handrail system bracket and a balustrade panel, the escalator outer decking including cover plate (1), wherein the escalator outer decking also includes a first bracket (3) mounted on the handrail system bracket (5), a retention member (2) secured to the cover plate (1) and an insertion strip (8), wherein the retention member (2) is connected to the first bracket (3) in a manner of embedding or snapping, and the insertion strip (8) is wedged between the cover plate (1) and the balustrade panel (9); such that when the outer decking is disassembled, the cover plate (1) and the retention member (2) can be taken down together by putting away the insertion strip (8) first and then lifting the cover plate (1) and the retention member (2) or pushing them towards the balustrade panel (9). The escalator outer decking the present invention has good configuration and can be dismantled easily during maintenance.

Abstract: A bi-directional escalator includes an ascending escalator and a descending escalator arranged in parallel and side-by-side with the ascending escalator. A driving machine drives an ascending driving unit and a descending driving unit at the same time. A controller controls operation of the driving machine. The driving machine includes an electric motor and a reduction gearbox connected to the electric motor. The reduction gearbox has a first output shaft and a second output shaft both arranged on the same side of the reduction gearbox.
