Abstract

The invention discloses a lipstick cap with an improved structure. The lipstick cap comprises an internal tube, an end cover and a pull hook, wherein the internal tube is positioned under the end cover by adopting the direction where a lipstick extends out as the upward side; an annular rail is arranged on the outer sidewall of the upper end of the internal pipe along the length direction of the internal tube of the lipstick; the upper end of the pull hook is fixedly arranged on the outer sidewall of the end cover while the lower end of the pull hook extends into the annular rail on the outer sidewall of the internal tube of the lipstick and can slip along the annular rail; an upper positioning point and a lower positioning point are arranged in the annular rail; and the upper end of the pull hook can be fixedly positioned to the upper positioning point and the lower positioning point of the annular rail. The lipstick cap further comprises a tower-shaped spring, wherein the upper end and the lower end of the tower-shaped spring are respectively and tightly propped against the end wall of the lower end of the internal tube of the lipstick and the end wall of the upper end of the end cover. According to the invention, the length of the lipstick cap is effectively reduced, so that the lipstick cap is small and attractive in appearance; the internal tube can move smoothly in the annular rail of the internal tube under the coordination of the metal pull hook and a shrapnel, and the circumstance that the lipstick cap can not be popped out can be prevented.

Description

Structure improved lipstick cap

Technical field

The present invention relates to a kind of lipstick cap, particularly the structure improved lipstick cap of one.

Background technology

Lipstick needs lipstick cap to open in use, taking off of current conveniently lipstick cap, interior pipe is provided with in lipstick cap, end cap and pull hook, pull hook is driven to move in the circular orbit of interior pipe bottom and realize axially-movable and the location of pipe by pressing end cap, this structure facilitates the ejection of lipstick cap, and at present because spring between interior pipe and end cap is all common spring, owing to still taking larger space after its contraction, bottom interior pipe, just form longer one section of groove structure deposited for spring, both material is wasted like this, make again lipstick cap long, small and exquisite not attractive in appearance, existing structure also easily occurs that pull hook lost efficacy or departed from the situation of endless glide, make lipstick cap smooth and easy not when ejecting.

Summary of the invention

In order to overcome above-mentioned defect, the invention provides a kind of structure improved lipstick cap, this structure improved lipstick cap uses smooth and easy, and small volume saves material and processing cost.

The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of structure improved lipstick cap, comprise interior pipe, end cap and pull hook, direction is stretched out for top with lipstick, interior pipe is positioned immediately below end cap, interior pipe upper end lateral wall is provided with one along the circular orbit in lipstick inner tube length direction, pull hook upper end is fixedly arranged on end cap lateral wall, pull hook lower end is stretched in the circular orbit in lipstick on pipe lateral wall and also can be slided along this circular orbit, be provided with in circular orbit, lower anchor point, pull hook upper end can be fixed positioned in the place of anchor point up and down of annular slide track, also be provided with turriform spring, these upper and lower two ends of turriform spring press closer the end wall of pipe lower end in lipstick and the end wall of end cap upper end respectively, during use, press end cap, end cap just moves downward the upper anchor point of disengaging circular orbit until the lower anchor point moving to circular orbit is relocated again with pull hook, now internal tube shrinks is to the one end near end cap, lipstick cap can cover on lipstick body, when needs use lipstick, only again need press end cap, pull hook departs from again after lower anchor point moves upward to anchor point under the elastic force effect of turriform spring is located again, now interior pipe stretches out principle end cap, now lipstick cap is upspring from lipstick body, lipstick cap is convenient to take off, can overlap completely due to during turriform spring contraction, substantially reduce the distance between end cap and interior pipe, shorten the length of whole lipstick cap, lipstick entirety is made to seem smaller and more exquisite exquisiteness, also material is saved during manufacture, be conducive to reducing costs, and turriform spring structure is stablized, conduct can not be there is, make the flexible more smooth and easy of interior pipe.

As a further improvement on the present invention, described pull hook is that metal material is made, and its intensity is large, not easily deforms and departs from circular orbit, positioning stablity.

As a further improvement on the present invention, also be provided with shell fragment and spring plate bracket, shell fragment one end and spring plate bracket are connected, shell fragment other end madial wall elasticity presses closer pull hook lateral wall, spring plate bracket upper end and end cap axial retention circumferencial direction can be rotationally connected, the circumferencial direction stop of axially can sliding of spring plate bracket lower end is located at outside interior pipe, this structure ensure pull hook lower end all the time annularly track slide, prevent it from departing from circular orbit.

The invention has the beneficial effects as follows: the present invention deposits the part of spring by the bottom using turriform spring and eliminate interior pipe, directly pull hook and circular orbit are arranged at interior pipe lateral wall, effectively shorten the length of lipstick cap, it is made to seem small and exquisite attractive in appearance, it is smooth and easy that the pull hook of metal material and shell fragment mating reaction guarantee that pull hook moves in the circular orbit of interior pipe, prevents lipstick cap and eject the situation appearance of losing efficacy.

Detailed description of the invention

Embodiment: a kind of structure improved lipstick cap, comprise interior pipe 1, end cap 2 and pull hook 3, direction is stretched out for top with lipstick, interior pipe 1 is positioned immediately below end cap 2, interior pipe 1 upper end lateral wall is provided with one along the circular orbit 11 of pipe in lipstick 1 length direction, pull hook 3 upper end is fixedly arranged on end cap 2 lateral wall, pull hook 3 lower end is stretched in the circular orbit 11 in lipstick on pipe 1 lateral wall and also can be slided along this circular orbit 11, be provided with in circular orbit 11, lower anchor point, pull hook 3 upper end can be fixed positioned in the place of anchor point up and down of annular slide track, also be provided with turriform spring 5, these turriform spring about 5 two ends press closer the end wall of pipe 1 lower end in lipstick and the end wall of end cap 2 upper end respectively, during use, press end cap 2, end cap 2 just moves downward the upper anchor point of disengaging circular orbit 11 until the lower anchor point moving to circular orbit 11 is relocated again with pull hook 3, now interior pipe 1 is retracted to the one end near end cap 2, lipstick cap can cover on lipstick body, when needs use lipstick, only need again press end cap 2, pull hook 3 departs from again after lower anchor point moves upward to anchor point under the elastic force effect of turriform spring 5 is located again, now interior pipe 1 stretches out principle end cap 2, now lipstick cap is upspring from lipstick body, lipstick cap is convenient to take off, owing to can overlap completely when turriform spring 5 shrinks, substantially reduce the distance between end cap 2 and interior pipe 1, shorten the length of whole lipstick cap, lipstick entirety is made to seem smaller and more exquisite exquisiteness, also material is saved during manufacture, be conducive to reducing costs, and turriform spring 5 Stability Analysis of Structures, conduct can not be there is, make the flexible more smooth and easy of interior pipe 1.
