In order to ensure the smooth rotation of the lipstick tube as a whole, oil is usually applied to the screw, but since there is a gap between the screw and the fork, the oil is easy to seep out from the gap after the oil is applied, polluting the surface of the product, and there will also be a phenomenon of string movement ; But when there is no gap between the two, there will be a squeaking sound, which will affect the user's use

Embodiment Construction
[0013] The embodiment of the improved structure of the bundle in the lipstick tube of the present invention will be described in detail below with reference to the accompanying drawings.
[0014] The improved structure of a lipstick tube bundle in the present invention comprises a barrel 1, a fork 2, a spiral 3 and a casing 4 which are coaxially threaded sequentially from the inside to the outside, and the outer wall of the barrel is provided with a protrusion, so The fork 2 is provided with a hollow guide groove matching the protrusion along its axial direction, and a spiral guide groove is provided on the inner wall surface of the spiral 3 along its axial direction and spirally rises. It can be passed through the hollow guide groove on the fork 2 and slid in the helical guide groove, and the position of the helix relative to the outer cover is fixed, the base 5 and the fork 2 are integrally formed, and the The base is axially positioned at the bottom end of the fork, and one...

The invention discloses an improved structure of a lipstick tube middle bundle. The improved structure comprises a bucket, a fork, a spiral and a jacket which are sequentially and coaxially sleeved, wherein a bulge on the outer wall of the bucket can penetrate through a hollowed-out guide groove in the fork and is embedded in a spiral guide groove on the spiral in a sliding way, and the spiral is fixed relative to the jacket; a base and the fork are integrally molded and are axially positioned at the bottom end of the fork, and a plurality of steps close to the outer wall of the fork are arranged at one end of the base towards the fork at intervals; a notch is arranged between the adjacent steps, and the hollowed-out arc-shaped guide grooves corresponding to the notches are circumferentially arranged at one end of the fork towards the base; an arc-shaped elastic connecting piece is arranged between each notch and the corresponding hollowed-out arc-shaped guide groove, and the two ends of each arc-shaped elastic connecting piece are respectively and fixedly connected onto the two steps adjacent to the arc-shaped elastic connecting piece; and one end face of the spiral towards the base can elastically prop against the elastic connecting pieces, so that the spiral and the fork generate elasticity and have no gap, and thus an overall lipstick tube rotates smoothly.
Description
technical field [0001] The invention relates to the field of lipstick tubes, in particular to an improved structure of a bundle in a lipstick tube. Background technique [0002] The traditional lipstick tube uses the gap between the spiral and the fork to control the smooth rotation by rotating the spiral, so that the barrel moves upward along the guide groove on the inner wall of the spiral until the lipstick is pushed out of the fork port. In order to ensure the smooth rotation of the lipstick tube as a whole, oil is usually applied to the screw, but since there is a gap between the screw and the fork, the oil is easy to seep out from the gap after the oil is applied, polluting the surface of the product, and there will also be a phenomenon of string movement ; But when there is no gap between the two, there will be a squeaking sound, which will affect the user's use. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invent...
