Description

Technical Field

[0001] This utility model relates to the field of cosmetic box lid technology, and in particular to a cosmetic lid with an opening and closing angle limiting structure. Background Technology

[0002] A cosmetic case is a container specifically designed for storing and carrying cosmetics. It is usually designed to be both beautiful and practical, helping users organize their cosmetics for convenient use in different situations. As an important storage tool for daily cosmetics, the practicality and convenience of the cosmetic case design directly affect the user's makeup experience. Traditional cosmetic cases generally consist of a box and a lid. The lid usually has a makeup mirror inside, allowing users to adjust their makeup while using cosmetics. However, existing cosmetic cases have certain limitations in the design of the lid's opening angle, making it difficult for users to adjust the mirror to a suitable viewing angle while applying makeup. Therefore, a cosmetic lid with an opening angle limiting structure is needed.

[0003] Traditional makeup case designs often lack effective opening and closing angle limiting structures. During the makeup process, users need to constantly adjust the opening and closing angle of the lid to ensure that the makeup mirror is at the best viewing angle. This means that users must use their hands to support or hold the lid, increasing the inconvenience of use. Since the makeup process usually takes a certain amount of time, especially for makeup that requires delicate operation, controlling the opening and closing angle of the lid with your hands for a long time will lead to wrist fatigue and soreness, causing physical discomfort to users and further affecting the user experience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cosmetic cap with an opening and closing angle limiting structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cosmetic lid with an opening and closing angle limiting structure includes a cosmetic box body. A connecting shaft with a hollow structure is fixed to one side of the top of the cosmetic box body. An arc-shaped groove is formed in the middle of the outer wall of the connecting shaft. A lid is provided on the top of the cosmetic box body, and the bottom side of the lid is rotatably connected to the connecting shaft. A knob with a cavity structure is rotatably connected to one end of the connecting shaft. A snap-fit ​​mechanism for snapping the cosmetic box body and the lid is provided on the other side of the top of the cosmetic box body. A limiting mechanism for limiting the lid is provided inside the connecting shaft. An installation groove is formed at the bottom of the lid, and a cosmetic mirror is embedded in the installation groove. The limiting mechanism effectively limits the opening and closing angle of the lid, ensuring that the cosmetic mirror is always at the best viewing angle when the user uses it. The user does not need to support or fix the lid with their hands, improving the convenience of use and avoiding the problem of wrist fatigue and soreness caused by prolonged hand control of the opening and closing angle of the lid, thus improving user comfort.

[0007] As a further embodiment of this utility model, the limiting mechanism includes a rotating shaft, which is rotatably connected inside the connecting shaft. One end of the rotating shaft passes through the outer wall of one end of the connecting shaft, and one end of the rotating shaft is fixed to the knob. A limiting block is fixed to the side wall of the rotating shaft, and one end of the limiting block is located outside the arc-shaped sliding groove. When it is necessary to limit the opening and closing angle of the lid, the knob is rotated first. The rotation of the knob drives the arc-shaped sliding groove to rotate, which in turn drives the rotating shaft to rotate inside the limiting block. When the limiting block rotates to the appropriate position, the lid stops rotating when the limiting block on one side of the top of the lid contacts it, thus completing the limitation of the opening and closing angle of the lid to ensure that the makeup mirror is at the best viewing angle.

[0008] As a further embodiment of this utility model, a circular slider is slidably connected inside the knob. Multiple extrusion rods are fixed in a circular pattern at equal intervals at one end of the circular slider. Multiple through slots are equally spaced in a circular pattern on the outer wall of one end of the knob, with each through slot corresponding to one of the extrusion rods. A threaded rod is rotatably connected to the other end of the circular slider, with one end of the threaded rod penetrating the outer wall of the other end of the knob. An internal threaded sleeve is fixed to the other end of the knob, fitting onto the side wall of the threaded rod, and the threaded rod and internal threaded sleeve are compatible. Two symmetrical protrusions are fixed on the inner sidewall. Two limiting grooves are symmetrically opened on the sidewall of the circular slider, and the two limiting grooves and the two protrusions correspond one-to-one. When the threaded rod is rotated, under the action of the internal threaded sleeve, the circular slider is pushed along the inside of the knob towards the end close to the connecting shaft. This causes multiple extrusion rods to pass through multiple through grooves and make close contact with the outer sidewall of one end of the connecting shaft. At this time, the friction between the contact surface of one end of the multiple extrusion rods and one end of the connecting shaft is large. With the cooperation of the two protrusions and the two limiting grooves, the knob can be restricted, so that the knob stops rotating.

[0009] As a further embodiment of this utility model, the snap-fit ​​mechanism includes a groove, which is located in the middle of the other side of the top of the cosmetic box body. A second magnet is fixed inside the groove, and a first magnet is fixed in the middle of the other side of the bottom of the box lid. The first magnet and the groove are compatible, and the magnetic poles of the adjacent ends of the first magnet and the second magnet are opposite in direction. The box lid can be quickly opened or closed by the first magnet and the second magnet, which is convenient to use.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the lid of this cosmetic box is designed with a limiting mechanism to effectively restrict the opening and closing angle of the lid, ensuring that the makeup mirror is always at the best viewing angle when the user is using it. The user does not need to support or fix the lid with their hands, which improves the convenience of use and avoids the problem of controlling the opening and closing angle of the lid with their hands for a long time. This can effectively reduce wrist fatigue and soreness and improve the user's comfort.

[0012] 2. The design of the fixing mechanism allows for quick opening or closing of the lid, making it convenient to use. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-8 A cosmetic lid with an opening and closing angle limiting structure includes a cosmetic box body 1. A connecting shaft 9 is fixed to one side of the top of the cosmetic box body 1, and the connecting shaft 9 has a hollow structure. An arc-shaped groove 10 is formed in the middle of the outer side wall of the connecting shaft 9. A lid 2 is provided on the top of the cosmetic box body 1, and one side of the bottom of the lid 2 is rotatably connected to the connecting shaft 9. A knob 13 is rotatably connected to one end of the connecting shaft 9, and the knob 13 has a cavity structure. A locking mechanism for locking the cosmetic box body 1 and the lid 2 is provided on the other side of the top of the cosmetic box body 1. The connecting shaft 9 has a hollow structure inside. The lid 2 is equipped with a limiting mechanism to restrict its opening and closing. The bottom of the lid 2 has an installation groove 3, and a makeup mirror 4 is embedded in the installation groove 3. During use, the limiting mechanism effectively restricts the opening and closing angle of the lid 2, ensuring that the makeup mirror 4 is always in the best viewing angle when the user uses it. The user does not need to support or fix the lid 2 with their hands, which improves the convenience of use and avoids the problem of wrist fatigue and soreness caused by prolonged hand control of the opening and closing angle of the lid 2, thus improving the user's comfort.

[0024] In this embodiment, the limiting mechanism includes a rotating shaft 11, which is rotatably connected to the inside of the connecting shaft 9. One end of the rotating shaft 11 passes through the outer wall of one end of the connecting shaft 9, and one end of the rotating shaft 11 is fixed to the knob 13. A limiting block 12 is fixed to the side wall of the rotating shaft 11, and one end of the limiting block 12 is located outside the arc-shaped slide groove 10. When it is necessary to limit the opening and closing angle of the lid 2, the knob 13 is rotated first. The rotation of the knob 13 drives the arc-shaped slide groove 10 to rotate, which in turn drives the rotating shaft 11 to rotate inside the limiting block 12. When the limiting block 12 rotates to the appropriate position, the lid 2 stops rotating when the limiting block 12 on one side of the top of the lid 2 contacts it, thus completing the limitation of the opening and closing angle of the lid 2 to ensure that the makeup mirror 4 is in the best viewing angle.

[0025] In this embodiment, a circular slider 16 is slidably connected inside the knob 13. Multiple extrusion rods 19 are fixed at equal intervals in a circular pattern at one end of the circular slider 16. Multiple through slots 14 are equally spaced in a circular pattern on the outer wall of one end of the knob 13, with each through slot 14 corresponding to one of the extrusion rods 19. A threaded rod 17 is rotatably connected to the other end of the circular slider 16, with one end of the threaded rod 17 penetrating the outer wall of the other end of the knob 13. An internal threaded sleeve 15 is fixed to the other end of the knob 13, fitting onto the side wall of the threaded rod 17. The threaded rod 17 and the internal threaded sleeve 15 are compatible. Two... Each of the two protrusions 18 and the circular slider 16 has two symmetrically arranged limiting grooves 20 on its side wall, with the two limiting grooves 20 corresponding one-to-one with the two protrusions 18. When the threaded rod 17 is rotated, under the action of the internal threaded sleeve 15, the circular slider 16 is pushed along the inside of the knob 13 towards the end closer to the connecting shaft 9, thereby causing multiple extrusion rods 19 to pass through multiple through grooves 14 and make close contact with the outer side wall of one end of the connecting shaft 9. At this time, the friction between the contact surface of one end of the multiple extrusion rods 19 and one end of the connecting shaft 9 is large. With the cooperation of the two protrusions 18 and the two limiting grooves 20, the knob 13 can be restricted, so that the knob 13 stops rotating.

[0026] In this embodiment, the snap-fit ​​mechanism includes a groove 7, which is located in the middle of the other side of the top of the cosmetic box body 1. A second magnet 8 is fixed inside the groove 7, and a first magnet 5 is fixed in the middle of the other side of the bottom of the box cover 2. The first magnet 5 and the groove 7 are compatible, and the magnetic poles of the adjacent ends of the first magnet 5 and the second magnet 8 are opposite. The box cover 2 can be opened or closed quickly by using the first magnet 5 and the second magnet 8, which is convenient to use.

[0027] Working principle: During use, the lid 2 is rotated to open. When the opening angle of the lid 2 needs to be limited, the knob 13 is rotated first. The rotation of the knob 13 drives the arc-shaped slide groove 10 to rotate, which in turn drives the rotating shaft 11 to rotate inside the limiting block 12. When the limiting block 12 rotates to the appropriate position, the threaded rod 17 is rotated. Under the action of the internal threaded sleeve 15, the circular slider 16 is pushed along the inside of the knob 13 towards the end near the connecting shaft 9. This causes multiple pressing rods 19 to pass through multiple through slots 14 and make close contact with the outer wall of one end of the connecting shaft 9. At this time, one end of the multiple pressing rods 19 and one end of the connecting shaft 9 are in close contact. The contact surface has high friction. With the cooperation of the two protrusions 18 and the two limiting grooves 20, the knob 13 can be restricted, so that the knob 13 stops rotating. This restricts the rotation of the shaft 11, preventing the shaft 11 from rotating, and the limiting block 12 stops rotating. Thus, when the limiting block 12 on the top side of the lid 2 contacts, the lid 2 stops rotating, thereby limiting the opening and closing angle of the lid 2. This ensures that the makeup mirror 4 is in the best viewing angle, eliminating the need for the user to support or fix the lid 2 with their hands. This increases the convenience of use and avoids the problem of wrist fatigue and soreness caused by prolonged hand control of the opening and closing angle of the lid 2, thus improving the user experience.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
