Description

Technical Field

[0001] This utility model relates to the field of beauty care technology, specifically an improved universal joint structure. Background Technology

[0002] Most beauty instruments and skincare devices on the market currently use a fixed-angle handle design, requiring users to constantly adjust the wrist angle of the robotic arm to suit the needs of different body parts. This design has the following drawbacks: 1. When the robotic arm moves at a small angle, it cannot flexibly adapt to the curves of different parts of the face or body; 2. The operation is not user-friendly and affects the user experience. If the angle is fixed, the front electrode cannot move and lie flat against the body surface during operation. 3. Some hard-to-reach areas require the user to contort their body to access them; While some existing products employ adjustable angle designs, the adjustment range is limited, and they are mostly limited to a few preset angles, making it impossible to achieve continuous and smooth self-rotation and overall rotational motion. Furthermore, the rotation mechanisms of these products are often complex, increasing manufacturing costs and maintenance difficulties. Utility Model Content

Furthermore, through the self-limiting effect of the cooperation between the outer shell of the motion component, the arc-shaped positioning plate, and the inner shell of the motion component, the stability and reliability during rotation can be effectively guaranteed. Moreover, the entire universal joint component has a simple structure, which can effectively reduce production costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides a technical solution: an improved universal joint structure, including a massager main unit 1, the upper end of the massager main unit 1 is connected to the universal joint assembly 2, the lower end of the universal joint assembly 2 is connected to the massage assembly 3, and the massager main unit 1 realizes the angle adjustment between itself and the massage assembly 3 through the universal joint assembly 2.

[0017] Universal joint assembly 2 includes an indicator light cover 21 that is fixed to the massager main unit 1 by screws, and the indicator light cover 21 is fixed to the connecting ring 22 by screws. An arc-shaped motion component housing 23 is fixed to the lower side of the connecting ring 22. The inner wall of the motion component housing 23 slides in contact with the outer wall of the arc-shaped positioning plate 24, and the arc-shaped positioning plate 24 is fixed on the connecting sleeve 25. The end of the motion component housing 23 contacts the connecting sleeve 25 to achieve positioning. The inner wall of the arc-shaped positioning plate 24 slides in contact with the outer wall of the motion component inner shell 26, and the end of the arc-shaped positioning plate 24 contacts the motion component inner shell 26 to achieve positioning. A threaded joint 261 is fixed to the upper end of the motion component inner shell 26, and the threaded joint 261 and the motion component housing 23 are nested together. The threaded joint 261 cooperates with the locking nut 262 to achieve the locking effect between the motion component inner shell 26 and the motion component housing 23. When using this improved universal joint structure, such as Figures 1-5As shown, the entire device is first assembled and fixed according to the above principle. When assembling the inner shell 26 of the motion component, the inner shell 26 of the motion component is assembled with the arc-shaped positioning plate 24 through the lower opening of the arc-shaped positioning plate 24. The outer shell 23 of the motion component is assembled with the upper side of the arc-shaped positioning plate 24, so that the arc-shaped positioning plate 24 is located between the inner shell 26 of the motion component and the outer shell 23 of the motion component. A dust cover assembly 27 is provided on the outside of the motion component housing 23, and the dust cover assembly 27 includes a corrugated dust cover 271 made of rubber material; an upper convex ring 272 is fixed on the upper side of the corrugated dust cover 271, and the upper convex ring 272 is locked to the motion component housing 23 by an upper pressure ring 273 and screws; a lower convex ring 274 is fixed on the lower side of the corrugated dust cover 271, and the lower convex ring 274 is locked to the connecting sleeve 25 by a lower pressure ring 275 and screws; After the device is assembled, such as Figures 1-5 As shown, during use, the massager main unit 1 is mounted on the robotic arm. The robotic arm moves the massager main unit 1, causing the massage component 3 to come into contact with the user (the massage component 3 can be replaced with other beauty instruments, care products, etc.). When it is necessary to adjust the angle between the massager main unit 1 and the massage component 3, a certain force is applied to the massager main unit 1. Combined with the sliding action between the motion component shell 23 and the arc-shaped positioning plate 24 and the sliding action between the arc-shaped positioning plate 24 and the motion component inner shell 26, the angle between the massager main unit 1 and the massage component 3 can be adjusted in any direction. With the elasticity of the corrugated dust cover 271, the angle adjustment can be ensured to better meet the actual use needs. During angle adjustment, the contact positioning between the end of the moving component housing 23 and the connecting sleeve 25, and the contact positioning between the end of the arc-shaped positioning plate 24 and the inner housing 26 of the moving component, can effectively prevent the moving component housing 23 from separating from the arc-shaped positioning plate 24 or the arc-shaped positioning plate 24 from the inner housing 26 of the moving component, thereby ensuring the normal operation of the device. In addition, with the function of the corrugated dust cover 271, it can achieve the function of isolation and dust prevention, preventing external dust from entering the device and causing increased friction, thereby affecting the normal use of the device.
