Abstract
Description
Technical Field
[0001] This utility model relates to the field of lipstick technology, specifically to retractable lipstick. Background Technology
[0002] Lipstick is a cosmetic product primarily used on the lips to enhance or alter their color. Its structure includes a main body containing the lipstick, which moves along the main body using a pusher. However, lipstick materials vary in hardness. For hard lipsticks, a conventional structure—where the pusher moves the lipstick directly—works without issue. But for softer lipsticks, a conventional structure is unsuitable. First, in a conventional structure, a significant portion of the lipstick is unsupported. Without support, the soft lipstick will deform, resulting in an undesirable shape after it extends. Second, a conventional structure only allows extension, not retraction or downward movement. Retraction only applies a downward pull to the bottom of the lipstick—one end is stressed, or only a small portion is stressed—while the rest remains unsupported and unstressed, leading to deformation or even tearing of the lipstick. Summary of the Invention
[0003] The purpose of this invention is to provide a retractable lipstick in which the lipstick body is always located inside the limiting tube and always in contact with the push rod. The limiting tube can support and limit the lipstick body, thereby preventing deformation. Furthermore, the push rod only applies upward force to the lipstick body and no downward force, thus preventing the lipstick body from deforming or even tearing due to force on the bottom. Therefore, this invention solves the problem that softer lipstick bodies are not suitable for existing push rod structures.
[0004] The purpose of this utility model is achieved as follows:
[0005] A retractable lipstick, including a casing, with the casing containing a liquid and a pushing component for moving the liquid up or down;
[0006] The pushing assembly includes a rotating rod one, a rotating rod two, a ratchet, a push rod, and a limiting tube. The bottom of the push rod is located inside the rotating rod one and is threadedly connected to the rotating rod one. The rotating rod two is sleeved on the outside of the rotating rod one and is threadedly connected to the outer shell. The ratchet is sleeved on the outside of the push rod and is located between the rotating rod one and the rotating rod two. An elastic element is provided between the ratchet and the rotating rod two. The ratchet tooth one of the ratchet includes an inclined surface one and a vertical surface one. Under the action of the elastic element, the ratchet tooth one always matches the ratchet tooth two at the top of the rotating rod one, thereby controlling whether the push rod and the rotating rod one rotate synchronously or relative to each other.
[0007] The limiting tube contains the material, and the bottom of the limiting tube is sleeved on the outside of the rotating rod two. The top of the push rod is located inside the limiting tube and in contact with the material. By rotating the rotating rod one, the rotating rod two is driven to rotate and moves upward due to the threaded connection. The limiting tube, the push rod, and the rotating rod one move upward as the rotating rod two moves upward until the rotating rod two can no longer move. At this time, the rotation of the rotating rod one is in the direction of the ratchet inclined surface one, and the push rod and the rotating rod one rotate relative to each other. The top of the push rod moves inside the limiting tube due to the threaded connection and pushes the material upward.
[0008] When it is time to retract, rotate lever one. At this time, the rotation of lever one is in the direction of the vertical plane of the ratchet, and the push rod and lever one rotate synchronously. Then, by rotating lever one in the opposite direction, lever two is driven to rotate and, due to the threaded connection, lever two moves downward. At this time, the limit tube, push rod and lever one move downward as lever two moves downward.
[0009] Preferably, the push rod includes a rod and a pushing part disposed at the top of the rod, and the rod has flat surfaces formed on both sides, and the ratchet has an elongated hole in the middle corresponding to the rod;
[0010] Or / and, the second ratchet includes a second inclined surface and a second vertical surface, wherein the second inclined surface is adapted to the first inclined surface, and the second vertical surface is adapted to the first vertical surface.
[0011] Preferably, the rotating rod 2 includes a threaded portion and a connecting portion disposed on the threaded portion, and the outer side of the connecting portion is provided with ribs to increase friction, and a limiting tube is sleeved on the outer side of the connecting portion, and the bottom of the limiting tube abuts against the top of the threaded portion.
[0012] Preferably, the push rod includes a rod and a pushing part disposed at the top of the rod, with the top of the pushing part protruding upwards, and a groove being formed at the bottom of the material corresponding to the pushing part.
[0013] Preferably, the rotating rod includes a middle section and mounting parts 1 and 2 disposed at both ends of the middle section. The rotating rod 2 is sleeved on the outside of the mounting parts 1, and the bottom of the rotating rod 2 abuts against the top of the middle section. The mounting parts 2 are used to connect with the rotating seat.
[0014] Preferably, the push rod is provided with protrusions on both sides, and the protrusions are used to adapt to the rotating rod to limit the range of movement of the push rod.
[0015] Preferably, the outer shell includes a main body and limiting members and a rotating seat disposed at both ends of the main body, wherein the limiting tube is located inside the limiting member, and the rotating seat is connected to the bottom of the rotating rod.
[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:
[0017] When the material moves upward, it moves within the limiting tube under the push of the push rod. When the material moves downward, it moves synchronously with the limiting tube and the push rod. Therefore, the material is always located within the limiting tube and is always in contact with the push rod. The limiting tube can support and limit the material, thereby preventing deformation. Furthermore, the push rod only applies an upward force to the material and no downward force, thus preventing the material from deforming or even tearing due to force on the bottom.

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0029] like Figures 1-6 As shown, the retractable lipstick includes a casing, and the casing contains a liquid 10 and a pushing component for moving the liquid 10 up or down.
[0030] The pushing assembly includes a rotating rod 1, a rotating rod 2, a ratchet 3, a push rod 4, and a limiting tube 5. The bottom of the push rod 4 is located inside the rotating rod 1 and is threadedly connected to the rotating rod 1. The rotating rod 2 is sleeved on the outside of the rotating rod 1 and is threadedly connected to the outer shell. The ratchet 3 is sleeved on the outside of the push rod 4 and is located between the rotating rod 1 and the rotating rod 2. An elastic element 6 is provided between the ratchet 3 and the rotating rod 2. The ratchet tooth 31 of the ratchet 3 includes an inclined surface and a vertical surface. Under the action of the elastic element 6, the ratchet tooth 31 is always adapted to the ratchet tooth 11 at the top of the rotating rod 1, thereby controlling whether the push rod 4 and the rotating rod 1 rotate synchronously or relative to each other.
[0031] Meanwhile, the limiting tube 5 contains the material body 10, and the bottom of the limiting tube 5 is sleeved on the outside of the rotating rod 2, while the top of the push rod 4 is located inside the limiting tube 5 and in contact with the material body 10.
[0032] Therefore, in actual use, rotating rod 1 drives rotating rod 2 to rotate, and due to the threaded connection, rotating rod 2 moves upward. The limiting tube 5, push rod 4 and rotating rod 1 move upward as rotating rod 2 moves upward, until rotating rod 2 can no longer move, that is, the threaded rotation has reached the end. At this time, the rotation of rotating rod 1 is in the direction of the inclined surface of ratchet 3, and the push rod 4 and rotating rod 1 rotate relative to each other. Furthermore, the top of push rod 4 moves within the limiting tube 5 due to the threaded connection and pushes the material 10 upward.
[0033] When it is time to retract, the first rotating rod 1 is rotated. At this time, the first rotating rod 1 rotates in the direction of the vertical plane of the ratchet 3, and the push rod 4 and the first rotating rod 1 rotate synchronously. Then, by rotating the first rotating rod 1 in the opposite direction, the second rotating rod 2 is driven to rotate and moves downward due to the threaded connection. At this time, the limit tube 5, the push rod 4 and the first rotating rod 1 move downward as the second rotating rod 2 moves downward.
[0034] Therefore, when the material body 10 moves upward, it moves within the limiting tube 5 under the push of the push rod 4. When the material body 10 moves downward, it moves synchronously with the limiting tube 5 and the push rod 4. Thus, the material body is always located within the limiting tube and is always in contact with the push rod. The limiting tube can support and limit the material body, thereby preventing deformation. Furthermore, the push rod only applies upward force to the material body and no downward force, thus preventing the material body from deforming or even tearing due to the force at the bottom.
[0035] like Figures 1-6 As shown, the structure of the ratchet 3 includes the structure between the ratchet 3 and the push rod 4. The push rod 4 includes a rod 41 and a pushing part 42 set on the top of the rod 41. The rod 41 has flat surfaces 421 formed on both sides, and the ratchet 3 has an elongated hole 32 in the middle corresponding to the rod 41.
[0036] Meanwhile, the structure between ratchet 3 and ratchet 11, namely ratchet 11 includes inclined surface 2 and vertical surface 2, and inclined surface 2 is adapted to inclined surface 1, and vertical surface 2 is adapted to vertical surface 1.
[0037] Secondly, the structure between the limiting tube 5 and the rotating rod 2 is as follows: the rotating rod 2 includes a threaded part 21 and a connecting part 22 provided on the threaded part 21, and the connecting part 22 is provided with ribs to increase friction on the outside of the connecting part 22, and the limiting tube 5 is sleeved on the outside of the connecting part 22, and the bottom of the limiting tube 5 abuts against the top of the threaded part 21.
[0038] Furthermore, the structure between the push rod 4 and the material body 10 is as follows: First, the push rod 4 includes a rod 41 and a pushing part 42 disposed on the top of the rod 41, and the top of the pushing part 42 protrudes upward, and the bottom of the material body 10 is provided with a groove corresponding to the pushing part 42.
[0039] Meanwhile, the structure between rotating rod 1 and rotating rod 2 is as follows: firstly, rotating rod 1 includes an intermediate section 12 and mounting parts 13 and 24 located at both ends of the intermediate section 12, and rotating rod 2 is sleeved on the outside of mounting part 13, and the bottom of rotating rod 2 abuts against the top of the intermediate section 12, and mounting part 2 is used to connect with rotating seat 7.
[0040] The structure between the rotating rod 2 and the mounting part 13 is as follows: First, a protruding strip 1 is provided on the outer side of the mounting part 13, and the rotating rod 2 is correspondingly slotted. Moreover, the structure between the mounting part 2 14 and the rotating seat 7 is as follows: First, a plate 1 and a plate 2 are respectively provided on the outer side of the mounting part 2 14 and the inner wall of the rotating seat 7, and the plate 1 and plate 2 are adapted to each other. When the rotating seat 7 rotates, the plate 1 is pushed by the plate 2, thereby driving the mounting part 2 14 to rotate.
[0041] like Figures 1-6 As shown, push rod 4 has protrusions 43 on both sides, and the protrusions 43 are used to adapt to rotating rod 2 to limit the range of movement of push rod 4. Specifically, rotating rod 2 has a through hole to allow push rod 4 to pass through, and the protrusions 43 abut against the inner wall of rotating rod 2 located outside the through hole to limit its movement.
[0042] like Figures 1-6 As shown, the outer shell includes a main body 8 and limiting members 9 and a rotating seat 7 disposed at both ends of the main body 8, and the limiting tube 5 is located inside the limiting member 9, and the rotating seat 7 is connected to the bottom of the rotating rod 1.
[0043] The structure between the rotating seat 7 and the main body 8 is as follows: firstly, a raised strip four is provided on the outer side of the rotating seat 7, and a corresponding groove is opened on the inner wall of the main body 8. Furthermore, the structure between the limiting tube 5 and the main body 8 is as follows: firstly, a raised edge is provided on the outer side of the limiting tube 5, and the raised edge is located at the top of the main body 8 to limit movement; secondly, a raised strip two for connection or a raised strip three for increasing friction is provided on the outer side of the end of the limiting tube 5 located inside the main body 8. Simultaneously, a cover 20 is fitted onto the outer side of the top of the limiting tube 5, and at least one protrusion is provided on the outer side of the limiting tube 5 to engage and increase friction.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
