It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.
[0018] Example 1:
[0019] like Figures 1 to 3 As shown, this utility model provides a lipstick extrusion tube, including a tube body 1 and a tube cap 2. A knob 3 is rotatably connected to the bottom of the tube body 1. A receiving cavity 4 is provided inside the tube body 1. A threaded rod 5 is fixed on the knob 3. A connecting plate 6 is threadedly connected to the threaded rod 5. A support frame 7 is provided on the connecting plate 6. An ejection mechanism 8 is provided on the tube body 1.
[0020] Example 2:
[0021] like Figures 1 to 3As shown, this utility model provides a lipstick extrusion tube, including a tube body 1 and a tube cap 2. A knob 3 is rotatably connected to the bottom of the tube body 1. A receiving cavity 4 is provided inside the tube body 1. A threaded rod 5 is fixed on the knob 3. A connecting plate 6 is threadedly connected to the threaded rod 5. A support frame 7 is provided on the connecting plate 6. An ejection mechanism 8 is provided on the tube body 1.
[0022] Rotating the knob 3 moves the threaded rod 5 and the connecting plate 6, thus pushing the lipstick refill out. The rotating connection between the knob 3 and the bottom of the tube 1 ensures ease of operation; the receiving cavity 4 provides a stable storage space for the lipstick refill; and the ejection mechanism 8 ensures the ejection of any remaining lipstick refill.
[0023] The support frame 7 includes a left support rod 9, a right support rod 10, and a base plate 11. The left support rod 9 and the right support rod 10 are both mounted on the connecting plate 6, and the tops of the left support rod 9 and the right support rod 10 are fixedly connected to the base plate 11.
[0024] The support frame 7 can evenly distribute the pressure on the connecting plate 6, improving the stability and reliability of the overall structure; the setting of the left support rod 9 and the right support rod 10 ensures the symmetry and balance of the support frame 7, further enhancing the stability of the structure; the fixed connection between the bottom plate 11 and the left support rod 9 and the right support rod 10 provides a stable support platform for the lipstick core, ensuring the smoothness of the extrusion process.
[0025] Furthermore, in another embodiment, the ejection mechanism 8 includes a base 12, which is fixed to the bottom of the knob 3. A push rod 13 is slidably connected to the base 12.
