Abstract
The utility model discloses an oil-free middle beam core for lipstick comprising a middle beam, a middle section, a bead, and a spiral, wherein the middle beam and the middle section are fixedly connected to each other, the inner circumferential surface of the spiral being provided with a spiral guide groove, the top end inserting to the middle section and being fastened to the inner wall in axial direction, the bottom end of the bead inserting to the inner chamber of the spiral and being fastened by the middle section longitudinally, the bottom end being provided with a projection which matches with the guide groove, the wall surface of the middle section being provided with a plurality of shrapnels, the inner side of each shrapnel being provided with a bump which is tightly abut against the external wall surface of the spiral. The bump on the inner side of the shrapnels of the middle beam and the middle section tightly clings to the external wall of the spiral. During the rotation of the spiral relative to the middle section, the bump and the spiral produce a friction therebetween due to effect of the shrapnels. The friction between the two is point-to-surface friction, so that it is very small. The utility model has the advantages of lubricating rotation, simple structure, and convenient installation.
Description
Technical field
The utility model relates to the cosmetic package field, relates in particular to Shu Xin in a kind of no oily lipstick tube.
Background technology
Middle Shu Xin is the topmost parts of lipstick tube, it mainly is made up of middle bundle, middle joint, pearl and spiral, the Shu Yuzhong joint is fixedly connected in general, spiral and middle nodal axisn are to fixing, pearl and middle pitch diameter are to fixing, in the middle relatively joint rotation process of spiral, spiral relies on the helicla flute on the inwall to drive pearl and moves back and forth in middle bundle.
Chinese patent 200820162956.1 discloses Shu Xin in a kind of lipstick tube, comprises middle bundle, middle joint, pearl and spiral; In joint be enclosed within on the pearl and and fix with middle bundle, middle joint also with spiral axial restraint, radially fixing with pearl, the outer surface of described pearl lower end is provided with screw thread, the inwall of spiral also is provided with the screw thread that the outer surface thread with the pearl lower end is complementary; The sidewall of middle joint has two upwardly extending supports, each fixing prerotation vane of bearing shell shape of the upper end of two supports, the inwall of prerotation vane is provided with axial protruding footpath, pearl also is provided with the groove that the protruding footpath with the prerotation vane inwall is complementary, the outside of the upper end of spiral has a circle projection, and the projection of spiral saves in described between sidewall upper face and the prerotation vane lower surface.But be somebody's turn to do not only assembly process complexity of middle Shu Xin, and be the friction of face face between spiral and the middle joint, damping is bigger, and rotation is lubricated inadequately.
Summary of the invention
The utility model provides Shu Xin in a kind of no oily lipstick tube, has solved existing middle bundle core assembly process complexity, and spiral and the lubricated inadequately problem of middle joint.
Shu Xin in a kind of no oily lipstick tube, comprise middle bundle, middle joint, pearl and spiral, middle Shu Yuzhong joint is fixedly connected, the spiral inner peripheral surface is provided with spiral gathering sill, during the top is stretched in the joint and with its inwall axial restraint, pearl bottom stretch into the spiral inner chamber and by in pitch diameter to fixing, the bottom is provided with the projection that matches with gathering sill, the joint wall is provided with some shell fragments in described, and each shell fragment inboard is provided with the salient point near the spiral outside wall surface.
The joint wall is provided with two symmetrically arranged shell fragments in described.
Described spiral outer wall is provided with bulge loop, and correspondingly middle joint inwall is provided with the cannelure that matches with bulge loop, makes the middle relatively nodal axisn of spiral to fixing.
Saving salient point and the spiral outer wall of going up the shell fragment inboard in the utility model among the Shu Xin is close to, spiral relatively in the joint rotation process in, because the effect of shell fragment, there is frictional force between salient point and the spiral, owing to be a face friction between them, frictional force is less, rotates very lubricated again, and simple in structure, equip also very convenient.
Description of drawings
Fig. 1 is the explosive view of Shu Xin in the utility model;
Fig. 2 cuts open figure for the axle of Shu Xin in the utility model;
Fig. 3 is a middle bundle core A partial enlarged drawing shown in Figure 2.
The specific embodiment
As shown in the figure, Shu Xin in a kind of, bundle 1, middle joint 2, pearl 3 and spiral 4 in comprising, fixedly connected with middle joint 2 in middle bundle 1 bottom, save in 2 inner chambers during spiral 4 tops are stretched into, outer wall is provided with a bulge loop 41, and correspondingly middle joint 2 inwalls are provided with the cannelure 21 that matches with bulge loop 41, makes and saves 2 axial restraints during spiral 4 relatively.Spiral 4 inwalls are provided with two spiral gathering sills 42.
In middle relatively joint 2 rotation processes of spiral 4, projection 33 is slided in gathering sill 42, in the sliding process, the pedestal 31 of pearl 3 also moves back and forth in middle bundle 1, salient point 24 is because the effect of shell fragment 23 has certain pressure to spiral 4, in rotation process, and salient point 24 friction screws 4, have certain torsion, feel is lubricated.
Claims (3)
