Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, the present utility model is a cosmetic pencil with a middle section and a rotary rod, which comprises a pen head 10, a middle section 201, a rotary rod 202 and a pen core (not shown). The middle section 201 and the rotating rod 202 are integrally formed to form a rod body 20. The lever body 20 is connected to the nib 10 and is capable of rotating with respect to the nib 10.

As shown in fig. 1 and 2, the rod body 20 has a receiving cavity 21 therein. A pen core cavity 11 communicated with the accommodating cavity 21 is arranged in the pen head 10. An outlet 12 communicated with the outside is arranged at the upper end of the refill cavity 11. The nib 10 is divided into a front end 101 and a rear end 102 inserted into the housing chamber 21.

As shown in fig. 2, a push rod 9 is provided in the accommodation chamber 21, and the push rod 9 is connected to the cartridge and drives the upper end of the cartridge to extend out of the cartridge chamber from the outlet.

The housing chamber 21 is divided into a screw chamber portion 211 and a connection chamber portion 212 connected to the tip of the screw chamber portion 211. Wherein the diameter of the connecting cavity portion 212 is larger than the diameter of the screw cavity portion 211. The rear end 102 of the nib 10 is inserted into the connecting chamber portion 211. The push rod 9 is divided into a screw portion 91 and a fixing head 92 connected to the front end of the screw portion 91.

The screw cavity 211 has an internal thread which engages with the screw 91 at a position close to the connection cavity 212. A stop step 111 is provided in the cartridge chamber 11 at a front portion near the outlet. The stopper step 111 can perform stopper limiting for the push rod 9.

The stationary head 92 has a stationary cavity therein. The tail end of the pen core is clamped in the fixing cavity.

Thus, the rod body 20 rotates relative to the pen point 10 to drive the push rod 9 to axially move, so that the pen core is pushed to be exposed out of the pen point 10 or retracted into the pen point 10.

As shown in fig. 2, 3 and 4, a plurality of ribs 801 extending in the axial direction are distributed on the outer wall of the fixing head 92. A plurality of axially extending detents 802 are spaced on the inner wall of the plunger cavity 11. The upper end of the clamping groove 802 extends to the stop step 111. Thus, when the protruding rib 801 is clamped into the corresponding clamping groove 802, the push rod 9 can only axially move along the clamping groove 802 and cannot rotate in the pen point.

As shown in fig. 2, 3 and 4, small projections 803 extending in the axial direction are provided at intervals on the inner wall surface of the fixing chamber. By adopting the technical scheme, the small protrusions 803 can play the roles of increasing friction force, positioning the pen refill, preventing the pen refill from rotating and increasing structural strength, and are beneficial to ensuring that the pen refill is firmly fixed in the fixing cavity.

As shown in fig. 2, a ring-shaped collar 13 is provided around the rear end 102 of the nib 10. The inner wall of the middle section 201 is provided with an annular groove 22 which is matched with the convex ring 13.

As shown in fig. 2, a sealing ring 7 is provided between the front portion of the section 201 of the body 20 and the rear end 102 of the nib 10.

The foregoing describes one embodiment of the present utility model in detail, but the description is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the utility model. All equivalent changes and modifications within the scope of the present utility model are intended to be covered by the present utility model.
