[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 and Figure 2 As shown, the utility model is a cosmetic pen with a middle section and a rotating rod integrated, comprising a pen head 10, a middle section 201, a rotating rod 202 and a pen core (not shown in the figure). The middle section 201 and the rotating rod 202 are an integrated structure to form a rod body 20. The rod body 20 is connected to the pen head 10 and can rotate relative to the pen head 10.
[0023] like Figure 1 and Figure 2 As shown, the rod body 20 has a receiving cavity 21. The pen head 10 has a core cavity 11 communicating with the receiving cavity 21. An outlet 12 communicating with the outside is provided at the upper end of the core cavity 11. The pen head 10 is divided into a front end 101 and a rear end 102 inserted into the receiving cavity 21.
[0024] like Figure 2 As shown, a push rod 9 is provided in the accommodating chamber 21, and the push rod 9 is connected to the pen core and drives the upper end of the pen core to extend out of the pen core chamber through the outlet.
[0025] The accommodating chamber 21 is divided into a screw chamber 211 and a connecting chamber 212 connected to the top of the screw chamber 211. The diameter of the connecting chamber 212 is larger than the diameter of the screw chamber 211. The rear end 102 of the pen tip 10 is inserted into the connecting chamber 211. The push rod 9 is divided into a screw portion 91 and a fixed head 92 connected to the front end of the screw portion 91.
[0026] The position of the screw cavity 211 near the connecting cavity 212 has an internal thread meshing with the screw portion 91. A stop step 111 is provided at the front position near the outlet in the refill cavity 11. The stop step 111 can stop and limit the push rod 9.
[0027] The fixing head 92 has a fixing cavity in it. The tail end of the pen core is clamped in the fixing cavity.
[0028] In this way, the rotation of the rod body 20 relative to the pen tip 10 can drive the push rod 9 to move axially, thereby pushing the pen core to be exposed outside the pen tip 10 or to be retracted into the pen tip 10.
[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a plurality of ridges 801 extending in the axial direction are distributed on the outer wall of the fixed head 92. A plurality of slots 802 extending in the axial direction are distributed at intervals on the inner wall of the refill cavity 11. The upper ends of the slots 802 extend to the stop step 111. Thus, when the ridges 801 are inserted into the corresponding slots 802, the push rod 9 can only move axially along the slots 802 and cannot rotate in the pen tip.
[0030] like Figure 2 , Figure 3 and Figure 4 As shown, in addition, small protrusions 803 extending axially are arranged at intervals on the inner wall surface of the fixed cavity. With the above technical solution, the small protrusions 803 can increase friction, position the pen core, prevent the pen core from rotating, and increase structural strength, which helps to ensure that the pen core is firmly fixed in the fixed cavity.
[0031] like Figure 2 As shown, a ring-shaped convex ring 13 is provided around the rear end 102 of the pen head 10. An annular groove 22 adapted to the convex ring 13 is provided on the inner wall of the middle section 201.
[0032] like Figure 2 As shown, a sealing ring 7 is provided between the front portion of the middle section 201 of the rod body 20 and the rear end portion 102 of the pen tip 10 .
[0033] In summary, the utility model simplifies the structure of the cosmetic brush by setting the middle section and the rotating rod as an integrated structure, facilitates assembly, and reduces costs. A convex ridge is set on the outer wall surface of the fixed head, and a card slot is set in the pen core cavity. In this way, when the convex ridge is inserted into the card slot, the push rod can only move up and down along the card slot and cannot rotate in the pen head. By setting a small protrusion on the inner wall surface of the fixed cavity, friction can be increased, the pen core can be positioned, and the pen core can be prevented from rotating.
[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
