Description

Technical Field

[0001] This utility model relates to the field of personal care device technology, and in particular to a nail grinder assembly. Background Technology

[0002] Existing nail grinders mostly employ a one-piece structure or a fixed-length cable connection, resulting in problems such as easy cable tangling, difficulty in storage, non-adjustable length during use, and poor portability. Especially during use, users often experience operational inconvenience due to cable length limitations, or find it difficult to store exposed cables, and cable tangling affects the device's aesthetics and safety. Furthermore, most existing nail grinders lack an effective dedicated placement structure; the grinder itself is usually left lying around when not in use, making it prone to falling or damage. Simultaneously, the overall device lacks a stable multi-angle support mechanism, making it difficult to adapt to operational needs in different environments. Although some products attempt to improve this through simple clamps or mounting bases, they still haven't achieved a holistic structural design that allows for easy disassembly, storage, and reliable fixation of the nail grinder and control module, failing to meet users' comprehensive requirements for device integration, portability, and ease of use.

[0041] Please see Figures 1 to 4This utility model provides a nail grinder assembly 100, including a control module 10 and a nail grinder 20. The control module 10 includes a power button 131, a display screen 132, a forward / reverse switch 133, a circuit board 134, a speed control knob 135, a charging port 136, and a battery 137. The control module 10 is electrically connected to the nail grinder 20. The control module 10 also includes a housing assembly 1 and a telescopic cable module 2 disposed in the housing assembly 1. The movable end 212 of the telescopic cable module 2 passes through the housing assembly 1 and is connected to the input end of the nail grinder 20 to achieve electrical connection. The circumferential side of the housing assembly 1 is provided with an annular fixing member 14 for placing the nail grinder 20. The annular fixing member 14 is detachably connected to the housing assembly 1. The back of the housing assembly 1 is provided with a rotating bracket 15.

[0042] Understandably, this design, through the integration of control components, telescopic cable module 2, ring-shaped fixing member 14, and rotating bracket 15, achieves centralized control, convenient storage, flexible placement, and support mechanisms for the armor grinder 20. The design of the telescopic cable module 2 allows its movable end 212 to be flexibly extended and retracted according to usage needs and can be completely stored within the housing component 1, avoiding problems such as tangling, inconvenient storage, or length limitations caused by traditional fixed cable lengths, thus improving the portability and operational freedom of the device. The main function of the ring-shaped fixing member 14 is to serve as a dedicated bracket or holder for the armor grinder 20 body. When the armor grinder 20 is separated from the control module 10... Afterwards, the user can directly snap or fix the nail polisher 20 onto the ring-shaped fixing member 14, thus providing a clear and secure location for the nail polisher 20. This design effectively solves the problem that the nail polisher 20 is easily lost after being placed carelessly, or damaged due to falling from a height. The ring-shaped fixing member 14 is detachably connected to the housing assembly 1, allowing users to choose to install or remove it according to their personal usage habits. It can also be removed when not in use to keep the housing simple, eliminating the hassle of searching for the nail polisher 20. At the same time, the rotating bracket 15 has a multi-angle adjustment function, which can realize the unfolded and retracted state of the housing assembly 1. In the retracted state, its back clip structure allows users to securely hang the entire housing assembly 1 on clothing pockets, belts, or bag straps, achieving a close-fitting storage and hands-free portability. In the unfolded state, the rotating bracket 15 can be unfolded 90°, allowing the housing assembly 1 to be tilted at a certain angle to the table, so that the screen and buttons are in the best viewing and operating position, conforming to ergonomics and making it easy for users to view the screen and operate the buttons.

[0043] Specifically, the movable end 212 of the telescopic cable module 2 passes through the housing assembly 1 and connects with the input end of the nail grinder 20; the annular fixing member 14 has a tapered cylindrical structure, with two protruding block-like structures extending from the outer side of the cylinder. Simultaneously, the inner wall of the cylinder has a contour that matches the part of the nail grinder 20 to be fixed, ensuring a good fit during contact. Secondly, the annular fixing member 14 achieves stable fixing of the nail grinder 20 through friction. That is, the tapered shape and contour of the inner wall of the annular fixing member 14 completely fit the shape of the corresponding part of the nail grinder 20, forming a tight surface contact. This effectively prevents relative sliding using friction; therefore, the nail grinder 20 must have a surface that matches the annular fixing member 14. The ring-shaped fastener 14 has no other button structure on its side and is located on the opposite side of the forward / reverse switch 133 and the speed control knob 135. It is detachably mounted on the side of the housing assembly 1 by means of a snap-fit ​​structure to fix the nail grinder 20. The rotating bracket 15 is connected to the back of the housing by a hinge and can be unfolded or erected to support the entire assembly for easy desktop use.

[0044] Furthermore, the annular fastener 14 and the housing assembly 1 are detachably connected by one of the following methods: magnetic attraction, snap-fit, or threaded connection.

[0045] Understandably, the multiple detachable connection methods provide a high degree of flexibility and ease of maintenance. Users can quickly disassemble the ring fastener 14 for cleaning or replacement as needed, while ensuring connection stability and assembly efficiency.

[0046] Specifically, the magnetic attraction method uses magnetic attraction to achieve automatic alignment and connection, which is simple to operate and durable; the snap-on method uses a mechanical snap-on structure to achieve a firm connection and one-click disassembly; the threaded method uses screws or knobs to lock the ring fastener 14 onto the housing, which is suitable for high vibration environments.

[0047] Please refer to further information. Figure 1 and Figure 3 When the rotating bracket 15 is unfolded and supports the housing assembly 1, the placement entrance of the annular fixing member 14 faces upward.

[0048] Understandably, this orientation design ensures that the nail grinder 20 is easy to access and store when placed, preventing accidental slippage, while optimizing human-computer interaction and maintaining a stable and intuitive operating posture when the product is supported.

[0049] Specifically, when the rotating bracket 15 is unfolded, the housing assembly 1 can be tilted at a certain angle to the table and placed on the table, with the opening of the annular fixing member 14 facing upward.

[0050] Please refer to further information. Figure 1 , Figure 5 and Figure 6The annular fastener 14 is provided with a T-shaped protrusion 141. The outer peripheral surface of the housing assembly 1 is provided with a T-shaped hole 114 that is adapted to the T-shaped protrusion 141. The housing assembly 1 is provided with a slot 115 that is adapted to the T-shaped protrusion 141 at the position corresponding to the T-shaped hole 114. The T-shaped protrusion 141 passes through the T-shaped hole 114 and engages with the slot 115, so that the annular fastener 14 and the housing assembly 1 can be detachably connected.

[0051] Understandably, the mating design of the T-shaped protrusion 141 and the slot 115 provides a mechanical interlock, ensuring a firm connection and alignment accuracy, while simplifying the installation process, reducing assembly complexity, and making it suitable for applications requiring frequent disassembly.

[0052] Specifically, the T-shaped protrusion 141 on the annular fastener 14 is a double T-shaped protrusion 141 with a T-shaped head; the T-shaped hole 114 is opened on the outer periphery of the housing assembly 1, and its size matches the protrusion; the slot 115 is located inside the housing and is snapped in place by an elastic wall structure; during installation, the protrusion is inserted along the T-shaped hole 114 and moved down to snap into the slot 115; during disassembly, it can be disassembled by moving it up and in the opposite direction.

[0053] Please refer to further information. Figure 1 and Figure 7 The rotating bracket 15 has rotating clamping parts 151 on both sides and a limiting abutment part 152 in the middle. The housing assembly 1 has a lower housing 12 and two positioning mating parts 122 that cooperate with the rotating clamping parts 151. The positioning mating part 122 includes a rotating shaft part 1221 and a limiting mating part 1222. The rotating clamping parts 151 are rotatably connected through the rotating shaft of the rotating shaft part 1221. During the rotation process, when the rotating bracket 15 rotates to the designed specific position, the limiting abutment part 152 on the rotating bracket 15 will abut against the limiting mating part 1222 on the lower housing 12.

[0054] Understandably, this rotation and limiting mechanism ensures the accurate positioning of the support when it is deployed and retracted, prevents excessive rotation or loosening, improves support stability and service life, and achieves a self-locking function through mechanical abutment.

[0055] Specifically, the rotating clamp 151 is a C-shaped metal or plastic part that covers the rotating shaft 1221; the limiting support part 152 is a protruding structure with a specific contour shape; the positioning mating part 122 includes a bearing seat and a rotating shaft fixed on the lower housing 12; when the bracket rotates to the use angle, the limiting support part 152 contacts the limiting mating part 1222 to form a mechanical stop; the rotating shaft part can use a pin or a bearing to reduce friction.

[0056] Furthermore, the inner wall of the annular fastener 14 is provided with an elastic buffer layer.

[0057] Understandably, the elastic buffer layer effectively prevents the armor grinder 20 from making hard contact with the fixing parts during storage, reducing wear and noise, while increasing the fixing force through friction, thus improving storage safety and product durability.

[0058] Specifically, the elastic buffer layer can be made of silicone or foam material and is attached to the inner wall of the annular fastener 14 by adhesive or insert injection molding. The surface can be designed with anti-slip texture to enhance the buffering and fixing effect.

[0059] Furthermore, the end of the rotating bracket 15 is provided with an anti-slip pad.

[0060] Understandably, the anti-slip pad increases the friction between the bracket and the contact surface, preventing slippage or displacement during use, ensuring the stability of the component on a smooth surface, and improving safety and user experience.

[0061] Specifically, the anti-slip mat is made of rubber or TPE material and is fixed to the end of the bracket by snaps or adhesives; its bottom surface can be designed with concave and convex patterns to increase the coefficient of friction and adapt to different desktop materials.

[0062] Please refer to further information. Figure 8 The housing assembly 1 includes an upper housing 11, a lower housing 12, and the upper housing 11 is detachably connected. The upper housing 11 is provided with a communicating opening 111 and a receiving groove 112. The movable end 212 of the telescopic cable module 2 passes through the opening 111 and is stored in the receiving groove 112. The receiving groove 112 is located on the outer surface of the upper housing 11.

[0063] Understandably, when the clipper 20 is not in use, the user can remove the movable end 212 of the telescopic cable module 2 from the clipper 20 and place it properly in the receiving slot 112. This design provides a fixed storage location for the connector head, avoiding cable tangling and a messy appearance caused by random hanging or placement. At the same time, the receiving slot 112 shields and protects the connector head, effectively preventing dust, moisture, and other contaminants from entering the interface or causing interface damage due to accidental collisions or scratches, thus extending the service life of the components. The support baffle 121 inside the lower housing 12 provides internal support for the telescopic cable module 2, ensuring its stability during operation. This storage design allows the movable end 212 of the telescopic cable module 2 to be neatly stored when not in use, avoiding cable tangling or damage, while also facilitating quick access and optimizing product appearance and space utilization.

[0064] Specifically, the opening 111 in the upper housing 11 provides a channel for the telescopic movement of the movable end 212 of the telescopic cable module 2. The receiving groove 112 is located on the outer surface of the upper housing 11 and communicates with the opening 111. At the same time, the receiving groove 112 and the power button 131 are located on the same side of the housing assembly 1 and are spaced apart, and their shape matches the movable end 212 of the telescopic cable module 2.

[0065] Please continue reading. Figure 8 The upper housing 11 is also provided with a mounting hole 113 that connects to the receiving groove 112. The housing assembly 1 includes a lower housing 12, and a support baffle 121 is provided on the lower housing 12. The support baffle 121 is exposed through the mounting hole 113 and closes the mounting hole 113.

[0066] Understandably, the support baffle 121 not only seals the mounting hole 113 to prevent dust from entering, but also provides structural reinforcement, enhances the overall strength of the housing, and facilitates maintenance and assembly.

[0067] Specifically, the mounting hole 113 is rectangular and located at the bottom of the receiving groove 112; the support baffle 121 can be made of metal or high-strength plastic and is fixed on the lower housing 12, with its surface flush with the outer surface of the mounting hole 113 of the upper housing 11, forming a complete enclosure.

[0068] Please refer to further information. Figure 1 , Figure 4 and Figure 9 The telescopic line module 2 is provided with a limiting block 22. When the movable end 212 of the telescopic line module 2 is retracted into the receiving groove 112, the limiting block 22 abuts against the support baffle 121 and the upper housing 11.

[0069] Understandably, the limit block 22 mechanism prevents the retractable cable from being over-retracted, ensuring that the movable end 212 is always in an accessible position, while dispersing stress through a supporting action, protecting the cable and internal components, and extending service life.

[0070] Specifically, the retractable cable module 2 includes a cable reel 21 and a limiting block 22. The limiting block 22 acts as a mechanical stop and has a cable outlet hole in the middle. Its installation position is precisely calculated. When the movable end 212 of the retractable cable module 2 is retracted to the predetermined minimum length through the cable outlet hole, the limiting block 22 contacts the support baffle 121 and the inner wall of the upper housing 11, forming a mechanical stop to prevent the cable reel 21 from over-retracting the cable, causing jamming or damage.

[0071] Please combine Figures 1 to 9The working process / principle of this utility model embodiment is briefly described as follows: The nail polisher assembly 100 provided in this utility model embodiment, through the integration of a telescopic cable module 2, an annular fixing member 14, and a rotating bracket 15, realizes a convenient storage, flexible placement, and support mechanism for the nail polisher 20. The design of the telescopic cable module 2 allows its movable end 212 to be flexibly extended and retracted according to usage needs and can be completely stored inside the housing assembly 1, avoiding the problems of tangling, inconvenient storage, or length limitations caused by traditional fixed cable lengths, thus improving the portability and operational freedom of the device. The main function of the annular fixing member 14 is to serve as a dedicated bracket or holder for the nail polisher 20 body. When the nail polisher 20 is separated from the control module 10, the user can directly insert or fix the nail polisher 20 onto the annular fixing member 14, thereby providing a clear and safe location for the nail polisher 20. This design effectively solves the problem that the nail polisher 20 is easily lost after being placed carelessly or damaged due to falling from a height. The ring-shaped fastener 14 is detachably connected to the housing assembly 1, allowing users to choose to install or remove it according to their personal habits. It can also be removed when not in use to keep the housing clean, eliminating the hassle of searching for the nail polisher 20. Meanwhile, the rotating bracket 15 has multi-angle adjustment capabilities, allowing the housing assembly 1 to be extended or retracted. In the retracted state, its clip structure allows users to securely attach the entire housing assembly 1 to a clothing pocket, belt, or bag strap, achieving a snug fit and hands-free portability. In the extended state, the rotating bracket 15 can be extended 90°, allowing the housing assembly 1 to be tilted at a certain angle on the table, placing the screen and buttons in the optimal viewing and operating position, conforming to ergonomics and facilitating user viewing of the screen and operation of the buttons.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
