Description

Technical Field

[0001] This utility model relates to the field of skin roller needle technology, and in particular to a self-locking skin roller needle. Background Technology

[0002] In today's beauty and skincare industry, people's demand for skin care and repair is increasing, prompting the continuous innovation of various beauty devices. Among them, the skin roller, as a highly regarded beauty tool, aims to precisely pierce the skin's surface through numerous tiny needles equipped on the roller, creating micro-channels and significantly improving the skin's absorption efficiency of various beauty liquids, providing a more effective way to improve and nourish the skin.

[0003] However, existing skin rollers have many limitations. Firstly, the assembly process requires extremely high directional precision. Users must carefully identify and confirm a specific direction to complete the assembly, a process that is not only time-consuming but also prone to failure due to misjudgment, requiring repeated attempts and significantly reducing ease of use. This causes considerable inconvenience for beauty professionals and consumers who use them for daily skincare. Secondly, existing connection methods primarily rely on peripheral friction to maintain the connection between the roller's components. In actual use, especially when the roller is subjected to significant external force, such as during rapid rolling, forceful pressing, or frequent angle adjustments, this friction-based connection structure lacks stability and is prone to detachment. Once detached, it not only interrupts the beauty process and affects skincare results but may also cause accidental skin damage, leading to adverse consequences such as scratches and infections, posing a potential threat to the user's personal safety.

[0004] In conclusion, given the significant deficiencies of existing skin rollers in terms of ease of assembly and connection stability, there is an urgent need to develop a novel skin roller structure to overcome these problems and meet the market's pressing demand for efficient, safe, and convenient beauty devices. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a self-locking skin roller with significant improvements in assembly convenience and connection stability.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a self-locking skin roller, including a bracket, a handle and a roller. The handle has a liquid inlet channel in the center, one end of the handle is provided with a screw thread, and the other end is provided with a self-locking structure. The self-locking structure includes a guide rod and a backstop hook. The bracket has a guide groove and a backstop groove. The guide groove and the backstop groove cooperate with the guide rod and the backstop hook to guide and lock. The cavity formed by the bracket and the handle after connection is a liquid storage part. A liquid outlet channel is opened in front of the liquid storage part. The roller is set in front of the liquid outlet channel and is rotatably connected to the bracket. Several needles are evenly distributed on the surface of the roller.

[0007] Furthermore, the self-locking structure is configured as two symmetrical structures.

[0008] Furthermore, a boss is provided at one end of the handle, the self-locking structure is provided on the boss, and the length of the guide groove is the sum of the axial length of the boss and the length of the guide rod.

[0009] Furthermore, the outer diameter of the boss is the same as the inner diameter of the bracket.

[0010] Furthermore, the bracket has rotating shafts on both sides, and the rollers have shaft holes at both ends. The shaft holes cooperate with the rotating shafts, so that the rollers are rotatably connected to the bracket.

[0011] Furthermore, the roller is provided with rotating shaft mounting grooves at both ends, and the rotating shaft mounting grooves are deeper from the edge to the center.

[0012] The beneficial effects of this self-locking skin roller are:

[0013] 1. A self-locking structure, including a guide rod and a check hook, is designed at one end of the handle. This design simplifies the operation process and eliminates the strict requirement for precise orientation identification in traditional assembly. During assembly, the operator does not need to identify the direction; simply align the guide rod with the pre-set guide groove inside the bracket, and then steadily push the handle inward until the check hook precisely engages with the corresponding check groove inside the bracket. During this process, the guide rod moves smoothly along the guide groove, not only providing a stable path for the handle's advancement and effectively preventing deviation and misassembly, but also, thanks to the ingenious cooperation of the check hook and check groove, instantly achieving a high-strength, high-stability, and reliable connection between the handle and the bracket.

[0014] 2. The rollers are equipped with mounting grooves that gradually decrease in depth from the edge to the center. When assembling the rollers and brackets, operators can easily identify the side with the deeper groove on the roller with the naked eye. Simply align this side precisely with the rotating shaft of the bracket and gently push it in. Guided by the gradual change in groove depth, the rotating shaft can slide along the groove to the bottom until it is fixed. The assembly process does not require complicated tools, which greatly shortens the assembly time and improves work efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figure 1 , 2The self-locking skin roller shown includes a support 2, a handle 1, and a roller 3. The handle 1 has a liquid inlet channel 13 in the center. One end of the handle 1 is provided with a screw thread 11, and the other end is symmetrically provided with two self-locking structures. The self-locking structure includes a guide rod 14 and a check hook 15. The support 2 has a guide groove 21 and a check groove 22. The guide groove 21 and the check groove 22 cooperate with the guide rod 14 and the check hook 15 respectively to guide and lock. The cavity formed by the support 2 and the handle 1 after connection is a liquid storage part 25. A liquid outlet channel 23 is opened in front of the liquid storage part 25. The roller 3 is located in front of the liquid outlet channel 23 and is rotatably connected to the support 2. Several needles are evenly distributed on the surface of the roller 3.

[0024] A boss 12 is provided at one end of the handle 1, and a self-locking structure is provided on the boss 12. The length of the guide groove 21 is the sum of the length of the boss 12 in the axial direction and the length of the guide rod 14. The outer diameter of the boss 12 is the same as the inner diameter of the bracket 2. After assembly, the boss 12 is inserted into the bracket 2 and fits tightly with the bracket 2, so that the liquid storage part 25 for containing beauty liquid is formed between the bracket 2 and the handle 1, and the sealing of the liquid storage part 25 is guaranteed.

[0025] The bracket 2 has rotating shafts 24 on both sides, and the roller 3 has shaft holes 32 at both ends. The shaft holes 32 cooperate with the rotating shafts 24, so that the roller 3 is rotatably connected to the bracket 2. The roller 3 has rotating shaft mounting grooves 31 at both ends. The rotating shaft mounting grooves 31 are from deep to shallow from the edge to the center. During assembly, the side of the deeper groove of the roller 3 is aligned with the rotating shaft 24 of the bracket 2 and pushed in, so that the rotating shaft 24 slides along the rotating shaft mounting groove 31 to the bottom of the groove and is fixed. The assembly is quick and reliable.

[0026] The installation and usage steps for a self-locking skin roller are as follows:

[0027] Step 1: Align the guide rod 14 of the handle 1 with the guide groove 21 of the bracket 2, and press it into the bracket 2 with a little force, keeping the guide rod 14 in close contact with the guide groove 21 during the process, until the guide rod 14 is fully embedded in the bracket 2. A slight "click" sound is heard, indicating that the handle 1 has been initially fixed in place.

[0028] Step 2: Observe the mounting grooves 31 of the rotating shaft on both sides of the roller 3, and make them precisely aligned with the rotating shaft 24 on the bracket 2. Gently push the roller 3 to the installation position to ensure that the roller 3 can rotate flexibly without any jamming. This means that the installation is successful.

[0029] Step 3: When using, first inject an appropriate amount of beauty serum, medicine, or other suitable liquid into the reservoir 25 through the inlet channel 13. Hold the handle 1 and slowly and evenly apply moderate pressure to the reservoir 25. As the pressure increases, the liquid stored in the reservoir 25 will be discharged through the outlet channel 23 at a stable flow rate to the surface of the roller 3, wetting the needle. Then, push the roller 3 on the skin with a steady force to achieve the roller needle therapy. The entire operation can be easily completed with one hand, bringing great convenience to the user.
