Abstract

The invention discloses an eyebrow pencil capable of preventing a pencil lead from being broken, which comprises a rotary tube, a pencil cap and a pencil lead, wherein one end of the pencil lead is fixedly connected to a screw rod through a limiting block, the screw rod is in threaded connection with a nut, the outer ring of the nut is fixedly connected with the inner wall of the rotary tube, and a spring is sleeved outside the screw rod and in a cavity at the opening end of the rotary tube. The other end of the refill extends into a protective sleeve opposite to the opening end of the rotary tube, and a rigid protective pen point capable of fixing and protecting the refill is fixedly arranged at the upper end of the protective sleeve. When the screw is used, the protective sleeve is fixed, the rotary pipe is rotated, the nut drives the screw rod and the pen core to move upwards along the direction of the threads, and the nut rotates to extrude the spring, so that the nut needs larger external force to continue to rotate. The aim of preventing the user from rotating out too many refills is achieved, and the possibility of refill fracture is reduced. The invention has simple operation and convenient use.

Description

Eyebrow pencil capable of preventing refill from being broken

Technical Field

The invention relates to the technical field of eyebrow pencils in cosmetics, in particular to an eyebrow pencil capable of preventing a pencil lead from being broken.

Background

Eyebrows are positioned above eyes on the face of a human body, have a certain growth period and can fall off naturally, and the eyebrows are an important component of the beauty of the face of the human body. The quality of eyebrows represents the beauty of the face, sometimes tools are needed for repairing eyebrows, the tools for repairing eyebrows are eyebrow pencils, the existing eyebrow pencils are pencil-type and push-tube-type, and the pencil core is pushed out to draw eyebrows when the eyebrow pencils are used.

In order to color the eyebrow pencil easily and not to stab skin, the pencil core of the eyebrow pencil in the current market is generally soft, so that a plurality of people can find that the eyebrow pencil is easy to break when using the eyebrow pencil, and great waste is caused.

The chinese application with application number 201721123524.5 discloses an automatic rotating pen, wherein two groups of fastening points are added on the screw rod of the automatic rotating pen, so that the over-shift force is increased, the over-shift is not easy, and the problems of easy trip and easy breakage of the pen core are solved. However, such an automatic rotating pen has the following disadvantages: in a common automatic eyebrow pencil, the pencil core is about 4 cm, and only two groups of buckling position clamping points are additionally arranged, so that the pencil core screwed out every time is easy to be longer, and the problem that the pencil core is easy to break cannot be well solved. Therefore, the eyebrow pencil capable of preventing the refill from being broken is provided to solve the problems.

Drawings

FIG. 1 is a front perspective view of an eyebrow pencil with a lead break prevention according to the present invention;

fig. 2 is an enlarged view of the eyebrow pencil at a1 for preventing the lead from breaking according to the present invention.

In the figure: 1 refill, 2 screws, 3 caps, 4 rubber protective layers, 5, a rotary tube, 6 springs, 7 nuts, 8 protective nibs, 9 protective sleeves, 10 inner protrusions, 11 outer protrusions, 12 grooves, 13 protrusions and 14 limiting blocks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an eyebrow pencil capable of preventing a pencil lead from being broken comprises a rotary tube 5 with an opening at one end, a pencil cap 3 buckled at the opening end of the rotary tube 5, and a pencil lead 1 arranged in a cavity of the rotary tube 5, wherein one end of the pencil lead 1 is fixedly connected to a screw rod 2 through a limiting block 14, the screw rod 2 is connected with a nut 7 through threads, and the outer ring of the nut 7 is fixedly connected with the inner wall of the rotary tube 5. And a spring 6 is arranged outside the screw rod 2, in a cavity between the nut 7 and the opening end of the rotating pipe 5.

The other end of the refill 1 passes through the opening of the rotary tube 5 and extends into a cavity of the protective sleeve 9 opposite to the opening end of the rotary tube 5, and the protective sleeve 9 is of a cylindrical structure with two open ends. There is a round lug 13 at the one end opening part of rotatory pipe 5, lug 13 and the recess 12 phase-match that is equipped with on the protective sheath 9 outer wall, fixed protective sheath 9, rotatory pipe 5 can be round protective sheath 9 and do circular motion. An inner bulge 10 is further arranged on the outer wall of the protective sleeve 9, an outer bulge 11 is arranged on the inner wall of the pen cap 3, and the eyebrow pencil is buckled through the inner bulge 10 of the protective sleeve 9 and the outer bulge 11 on the pen cap 3.

Generally, a gap between the protective sleeve 9 and the pen core 1 is large, the pen core 1 is made of soft material, and the eyebrow pencil is very easy to break in the using process, so that the rigid protective pen point 8 is fixedly arranged at the upper end of the protective sleeve 9, and the protective pen point 8 can be almost tightly attached to the pen core 1 to play a role in protecting the pen core 1.

In addition, in order to prevent the broken pencil core caused by the vibration of the eyebrow pencil during the placement process, the rubber rings 4 are arranged on the outer walls of the pencil cap 3 and the protective sleeve 9, so that the broken pencil core caused by the vibration is reduced.

When the pen is used, the pen cap 3 is opened, the protective sleeve 9 is fixed, the rotary tube 5 is rotated, the screw rod 2 moves upwards along the direction of the screw thread, and the pen core 1 moves upwards simultaneously under the driving of the screw rod 2. Because the outside cover of screw rod 2 is equipped with spring 6, when nut 7 upwards moved on screw rod 2, extrusion spring 6, then need bigger external force just to make nut 7 continue to rotate, can play and remind the user at the in-process that uses, only the effect of the less refill of back-out to play the effect that prevents the refill fracture. When the eyebrow pencil is used, the protective sleeve 9 is fixed, the rotating tube 5 is rotated, the pencil core 1 moves downwards to the inside of the protective pencil head 8, and finally the pencil cap 3 is buckled.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention should be covered by the scope of the present invention.
