Exterior and interior cover releasing mechanism
Technical field
It the utility model is related to the releasing mechanism that a kind of top cover to bottle cap and inner cap are departed from.
Background technology
The bottle cap of cosmetic bottle generally comprises top cover and inner cap, wherein top cover be enclosed in cover protection inner cap, inside covering has
Internal thread, so coordinate with bottle.In actual production process, single part presence in two parts of inner cap and top cover be present and lack
The problem of falling into, two parts are such as all lost, then waste of resource, need to separate above-mentioned two part successively.
Utility model content
The purpose of this utility model is to provide a kind of exterior and interior cover releasing mechanism, and how solution is departed from top cover and inner cap
Technical problem.
Exterior and interior cover releasing mechanism, including outer fixture, inner sleeve, operation panel, the cylinder with expansion link, air cylinder support;It is outer solid
Determine part boring and be provided with above-mentioned inner sleeve;The internal diameter of the outer fixture is between the internal diameter and external diameter of enclosing cover;At the top of inner sleeve
Side coordinates with inner cap, and the expansion link of boring and cylinder coordinates;Operation panel is fixed on outer fixture and inner sleeve bottom, the behaviour
Make the movable span for having for inner sleeve lifting on plate;Air cylinder support is fixed on the bottom of operation panel and linked together with cylinder.
The inner sleeve is spirally connected or snapped connection with inner cap.
The expansion link is spirally connected or snapped connection with inner sleeve.
The beneficial effects of the utility model are:Due to being provided with outer fixture and inner sleeve, the inner cap of wherein cosmetic bottle is interior
Set is fixed, when it is interior be enclosed on moved vertically down under the drive of motion bar when, the enclosing cover of cosmetic bottle by outer fixture block so as to
Realize the disengaging with inner cap.

Embodiment
It refer to Fig. 1 to Fig. 5, the exterior and interior cover releasing mechanism in figure, including an outer inner sleeve 2, one of fixture 1, one
4, one, the cylinder air cylinder support 5 of operation panel 3, one.
Outer fixture 1 is a cylinder, and its boring is provided with above-mentioned inner sleeve 2;Outer fixture 1 is overall to use irony
Material or nylon material.The internal diameter of the outer fixture 1 is between the internal diameter and external diameter of enclosing cover 62, so the outer fixture 1
The outer fixture 62 of cosmetic bottle can be blocked but not block the inner cap 61 of cosmetic bottle, thus be avoided that interference.
The top-side of inner sleeve 2 has external screw thread 21, and inside has internal thread, and the inner cap 61 of the external screw thread 21 and cosmetic bottle is matched somebody with somebody
Close, internal thread coordinates with motion bar 4.Inner sleeve 2 can also be connected and fixed with inner cap 61 by way of buckle.
Operation panel 3 is fixed on outer fixture 1 and the bottom of inner sleeve 2, has the movable span lifted for inner sleeve 2 on the operation panel 3
31、
There is expansion link 51, it does expanding-contracting action in the presence of ambient pressure, so drives inner sleeve 2 to do on cylinder 5
Lower lifting action and then make it that inner cap 61 and enclosing cover 62 are departed from.The cylinder 5 mainly passes through conventional air valve and extraneous source of the gas
Connection.
