With the development of society and the demands of job sites, liquid cosmetic pens become more attractive products for women because of the characteristics of portability and easiness in making up. The production line of liquid cosmetic pens is also becoming mature. With the continuous development of the production of liquid cosmetic pens, the traditional liquid cosmetic pens with liquid pushing and discharging functions are abandoned gradually, and instead, a rotary liquid cosmetic pen with more uniform liquid discharging and less leakage of cosmetic liquid is adopted.

At present, the existing rotary liquid cosmetic pencil can control the liquid outlet amount of the cosmetic liquid through rotation. However, in the actual operation, the cosmetic liquid is decomposed into a semisolid state at the outlet due to the fact that the cosmetic liquid is stored in the cosmetic pen for a long time. When the cosmetic liquid is used, the cosmetic liquid can be extruded again by using larger force, and in the rotating process, the larger force can cause the connection between the rear cover part of the cosmetic pen and the pen tube to be loose, and the larger force is needed to be used after the connection is loose, so that the experience is definitely reduced for female users; on the other hand, the back cover and the pen tube are loosened, so that the cosmetic liquid in the pen tube can be leaked. It is therefore desirable to provide a tamper-resistant rotary fluid pen.

The rotary ring 54 is internally provided with a waist-round matching hole 543 in a penetrating way, and matching threads 544 are arranged on the inner wall of the matching hole 543 in a surrounding way. The waist circle of the matching hole 543 is consistent with the threaded rod 52, the threaded rod 52 can be inserted into the matching hole 543, and the matching thread 544 is meshed with the thread outside the threaded rod 52.

The working principle of the anti-loosening rotary liquid pen provided by the utility model is as follows:

before the liquid pen is used, each component is installed, the rotating ring 54 is inserted into the threaded rod 52 in a rotating mode through the matching of threads, and then the elastic piece 55 and the positioning ring 53 are installed below the rotating ring 54 in sequence. After the installation, the threaded rod 52 is inserted into the rotating rod 51, the rotating rod 51 is inserted into the tail cap seat 4, and the locking portion 541 is inserted into the positioning hole groove 43 by positioning the positioning groove 542, so that the connection between the rotating assembly 5 and the tail cap seat 4 is completed. Finally, the lower half part of the rotating rod 51 is completely inserted into the mounting seat 31, so that the tail cover seat 4 and the tail cover 3 are connected in a rotating way. After the tail cap 3 is connected with the tail cap seat 4, the tail cap seat 4 is tightly connected inside the pen tube 1 through the dual functions of the axial installation groove 44 on the outer side wall of the tail cap seat and the fixing seat 41.

When a liquid pen is required to be used, the tail cover 3 is slowly rotated, the rotary rod 51 rotates synchronously, and the rotary rod 51 can only rotate unidirectionally under the action of the ratchet wheel 512 and the pawl 531. The rotating rod 51 rotates to drive the rotating ring 54 to move towards the side close to the limit ring 521, the axial groove 42 on the inner wall of the tail cover seat 4 limits the positioning ring 53 to return to the original position, and at the moment, the force generated by the rotation of the positioning ring 53 is transmitted to the rotating ring 54 through the elastic piece 55, and the rotating ring 54 rotates. Since the rotary ring 54 is fixedly mounted in the tail cap seat 4 by the engagement portion 541, the rotary ring 54 does not move toward the stopper 521, but moves the threaded rod 52 relatively toward the inside of the pen container 1 by engagement of the threaded rod 52 with the thread 544, thereby completing squeezing of the cosmetic liquid in the pen container 1 and allowing the cosmetic liquid to ooze out for makeup.

It will be apparent that the embodiments described above are merely some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
