Description

Technical Field

[0001] This utility model relates to the technical field of nail art, and specifically to a button flipping mechanism for a nail lamp. Background Technology

[0002] Traditional nail lamps mostly use ultraviolet (UV) light sources, with a peak wavelength of 370nm, which is within the visible light range and does not directly harm the eyes. UV light sources can effectively activate the photoinitiators in the phototherapy gel, achieving rapid curing. At the same time, they also have certain drying, sterilization, and disinfection effects, ensuring the durability and hygiene of the nail art. The equipment has low maintenance costs and is easy to operate, making it suitable for widespread use in professional nail salons or home environments, with outstanding economic practicality.

[0003] However, the button design of traditional nail lamps generally has problems such as fixed operating angle and high risk of accidental touch. Fixed buttons require users to passively adapt to the angle of the device, and buttons exposed to the outside of the device are prone to accidental operation due to external pressure or contact with foreign objects when not in use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by providing a button flipping mechanism for nail lamps. Through the cooperation of the flipping base and the rotating shaft-slide groove of the button box, dynamic adjustment of the button operation angle is achieved. When the user applies force to the surface of the button box, the rotating shaft rotates along the slide groove trajectory, allowing the button box to flip freely within the range of 0° to 90°. This solves the limitation of fixed button angles in traditional nail lamps. When used on a desktop, the user can flip the button box to a 90° upright position, allowing the fingers to press the buttons vertically, significantly reducing hand fatigue caused by prolonged operation. When using the device handheld, the button box can be fitted against the device surface. The flat appearance formed by the flipping box and the upper shell effectively avoids misoperation caused by external pressure or contact with foreign objects. The protrusions on the inner sides of the two end plates of the flipping base and the limiting slots on the side of the rotating shaft of the button box form mechanical interference. When the protrusions contact the end of the slot, the flipping action is physically restricted, preventing excessive rotation of the button box from causing wire breakage and ensuring stable button operation within the set angle. This solves the technical problems of easy accidental button presses and a single operating angle in traditional nail lamps.

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

[0006] The button flipping mechanism of the nail lamp includes a flipping base, a button box rotatably connected to the flipping base, a circuit board disposed inside the button box, and several buttons disposed on one side of the circuit board. The circuit board is used to receive and process electrical signals emitted by the buttons. Each button passes through one side of the button box. The button is connected to the circuit board through a pin to establish electrical contact to achieve signal conduction. The flipping base is used to adjust the flipping angle of the button box. The button box is used to install the circuit board and buttons. The buttons are used to emit corresponding electrical signals according to user needs. The button flipping mechanism is connected to the main body through the flipping base.

[0007] The flip base has a cavity with two open sides, which is used to cooperate with the key box to flip. A nut post is provided on the outer side of each end plate of the flip base, which is used to fix the flip base to the main body by bolts. A wire groove is provided on one of the flip surfaces of the flip base, which is used to pass through the discharge wire. A sliding groove is provided on each end plate of the flip base, which is used to limit the movement of the key box.

[0008] The flip base has a protrusion on the inner side of each of its two end plates, which is used to limit the flip angle of the button box.

[0009] The button box includes a main body disposed within the cavity and a bottom cover covering the main body. The main body is used to install the button and circuit board in conjunction with the bottom cover, and the bottom cover is used to form a protective cavity in conjunction with the main body to prevent accidental damage to the circuit board.

[0010] The main housing has a rotating shaft at each end, which is used to cooperate with the sliding groove of the flip base to realize the flipping action of the key box; a limiting slot is provided on one side of the rotating shaft, which cooperates with the protrusion of the flip base to limit the flipping angle of the key box.

[0011] The bottom cover is provided with a wire hole for passing through a discharge wire; the inner side of the bottom cover is provided with at least two threaded posts for fixing the bottom cover to the main body by bolts.

[0012] The main body of the button flipping mechanism includes an upper shell and a bottom plate. The bottom plate is installed below the upper shell and forms a nail cavity with an opening on one side. An electronic control board and a light board, sensor, switch, display, power supply and power socket are installed inside the upper shell. The electronic control board is electrically connected to the circuit board.

[0013] One side of the upper shell is provided with an installation port for installing the button flipping mechanism. The installation port is provided with a limiting part that matches the flipping base. The limiting part is used to limit the flipping box through mutual cooperation with the flipping base. At each end of the limiting part is a threaded post that matches the nut post of the flipping base. The threaded post is used to be threadedly connected to the nut post by bolts.

[0014] The beneficial effects of this utility model are as follows: By cooperating with the rotating shaft and sliding groove of the flip base and the button box, the dynamic adjustment of the button operation angle is realized. When the user applies force to the surface of the button box, the rotating shaft rotates along the sliding groove trajectory, allowing the button box to be freely flipped within the range of 0° to 90°. This solves the limitation of the fixed button angle of traditional nail lamps. When used on a desktop, the user can flip the button box to a 90° upright position, allowing the fingers to press the buttons vertically, significantly reducing hand fatigue caused by long-term operation. When using the device handheld, the button box can be attached to the surface of the device. The flat appearance formed by the flip box and the upper shell effectively avoids misoperation caused by external pressure or contact with foreign objects. The protrusions on the inner side of the two end plates of the flip base and the limiting slots on the side of the rotating shaft of the button box form mechanical interference. When the protrusions contact the end of the slots, the flipping action is physically restricted, which not only prevents the button box from rotating excessively and causing the wires to break, but also ensures that the buttons work stably within the set angle. This solves the technical problems of traditional nail lamp buttons being prone to accidental touches and having a single operating angle. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figure 1-15As shown, this utility model relates to a button flipping mechanism for a nail lamp. The button flipping mechanism includes a flipping base 1, a button box 2 rotatably connected to the flipping base 1, a circuit board 3 disposed inside the button box 2, and a plurality of buttons 4 disposed on one side of the circuit board 3. The circuit board 3 is used to receive and process electrical signals emitted through the buttons 4. Each button 4 passes through one side of the button box 2. The buttons 4 are connected to the circuit board 3 through pins to establish an electrical contact connection to achieve signal conduction. The flipping base 1 is used to coordinate with the flipping angle adjustment of the button box 2. The button box 2 is used to mount the circuit board 3 and the buttons 4. The buttons 4 are used to emit corresponding electrical signals according to user needs. The button flipping mechanism... The flip base 1 is connected to the main body 5. When the button box 2 is assembled to the main body 5, its working surface is lower than the surface of the upper shell, making it less likely for the buttons 4 on the button box 2 to be accidentally pressed. The flip base 1 is the basic support frame for the button flipping mechanism. Its two-sided open cavity 10 provides the physical space for the button box 2 to accommodate and achieve the flipping action. The nut post 12 on the outer side of its two end plates 11 is fixedly connected to the threaded part 502 of the mounting port 500 of the upper shell 50 of the nail lamp main body 5 by bolts, ensuring the stable assembly of the button flipping mechanism and the main body 5. The sliding groove 14 in the cavity 10 and the rotating shaft 200 of the button box 2 cooperate to form a mechanical guide structure for the flipping action. When the user applies force to the surface of the button box 2, When the key box 2 rotates, the rotating shaft 200 rotates along the circular surface of the slide groove 14. During this process, the protrusions 15 on the inner sides of the end plates 11 of the flip base 1 and the limiting slots 201 on the side of the rotating shaft 200 of the key box 2 form mechanical interference, allowing the key box 2 to rotate freely within the range of 0° to 90°. When the protrusions 15 contact the end of the slots 201, the flipping action is physically restricted to prevent the key box 2 from rotating excessively and causing the wires to break. The key holes on the surface of the key box 2 provide an installation channel for the key 4. The internal cavity accommodates the circuit board 3. The bottom cover 21 is locked with the main box 20 through the threaded post 211 to form a sealed inner cavity, which isolates the circuit board 3 from the external environment and effectively resists moisture, dust and grease. To prevent corrosion from chemical reagents that may come into contact during the nail lamp process, the bottom cover 21's wire hole 210 is axially aligned with the wire groove 13 of the flip base 1, ensuring that the electrical wires can be orderly led out from the circuit board 3 to the electrical control board 53 of the nail lamp body 5. At the same time, protective measures such as corrugated pipe wrapping can further prevent the wires from being pulled or bent during the flipping process. When the user presses the button 4, it triggers the corresponding contact switch on the circuit board 3, converting the mechanical action into an electrical signal. This signal is transmitted to the electrical control board 53 of the nail lamp body 5 via the wire, which can control the lamp board 54 to turn on and off, adjust the irradiation time, or switch the working mode. The fixed installation method of the circuit board 3 and the button box 2 ensures the stability of signal transmission during the flipping process.The flip-up design of the button box 2 allows users to adjust the orientation of the buttons 4 according to their operating habits or device placement. For example, when using it on a desktop, the button box 2 can be flipped to a 90° upright position for vertical finger pressing, while when holding the device 5, it can be fitted to the surface of the device 5 to avoid accidental touches. This dynamic adaptation capability significantly improves operating comfort and the portability of the device 5.

[0034] like Figure 4-7 As shown in Figure 11, the flip base 1 has a cavity 10 with openings on both sides, which is used to rotate the key box 2. A nut post 12 is provided on the outer side of each of the two end plates 11 of the flip base 1, which is used to fix the flip base 1 to the main body 5 with bolts. A wire groove 13 is provided on one of the flipping surfaces of the flip base 1, which is used to pass discharge wires. A sliding groove 14 is provided on each of the two end plates 11 of the flip base 1, which is used to limit the movement of the key box 2. The cavity 10 inside the flip base 1 provides operable physical space for the key 4 of the key box 2 through its two-sided opening. The sliding groove 14 cooperates with the rotating shaft 200 of the key box 2, and the limiting groove 201 cooperates with the protrusion 15. The flip angle of the button box 2 is limited, allowing it to rotate within a range of 0° to 90° to adapt to different operating scenarios. At the same time, the limiting part 501 on the cavity forms a radial constraint on the rotation axis 200 of the button box 2, ensuring smooth axial rotation during the flipping action. The nut column 12 is the connection interface between the flipping base 1 and the nail lamp body 5. It forms a rigid connection with the threaded part 502 of the mounting port 500 of the upper shell 50 of the body 5 through the symmetrical layout of the outer sides of the two end plates 11, thereby maintaining the stability of the flipping action of the button box 2. The wire groove 13 is set on the end face of the flipping base 1, providing a passage for the wires from the circuit board 3 of the button box 2 to the nail lamp body 5. The width of the groove matches the diameter of the wire bundle, avoiding the risk of the wires being pinched during the flipping process.

[0035] like Figure 3-6 As shown, each of the two end plates 11 of the flip base 1 has a protrusion 15 on its inner side, which is used to limit the flip angle of the button box 2.

[0036] like Figure 5 , 15 As shown, the button box 2 includes a main box 20 disposed in the cavity 10 and a bottom cover 21 covering the main box 20. The main box 20 is used to cooperate with the bottom cover 21 to install the button 4 and the circuit board 3. The bottom cover 21 is used to cooperate with the main box 20 to form a protective cavity to prevent accidental damage to the circuit board 3.

[0037] like Figure 1-6As shown in Figure 10, a rotating shaft 200 is provided at each end of the main housing 20. The rotating shaft 200 is used to cooperate with the slide groove 14 of the flip base 1 to realize the flipping action of the key box 2. A limiting groove 201 is provided on one side of the rotating shaft 200 to cooperate with the protrusion 15 of the flip base 1. The limiting groove 201 is used to cooperate with the protrusion 15 to limit the flipping angle of the key box 2.

[0038] like Figure 8 As shown, the bottom cover 21 is provided with a wire hole 210 for passing through the discharge wire; the inner side of the bottom cover 21 is provided with at least two threaded posts 211 for fixing the bottom cover 21 to the main housing 20 by bolts.

[0039] like Figure 1-2 As shown in Figure 7, the main body 5 of the button flipping mechanism includes an upper shell 50 and a base plate 51. The base plate 51 is installed below the upper shell 50 and forms a nail cavity 52 with an opening on one side. The upper shell 50 is equipped with an electronic control board 53 and a light board 54, a sensor, a switch 55, a display 56, a power supply 57, and a power socket 58, which are electrically connected to the electronic control board 53. The electronic control board 53 is electrically connected to the circuit board 3.

[0040] like Figure 12 As shown, one side of the upper shell 50 is provided with a mounting port 500, which is used to install the button flipping mechanism. A limiting part 501 matching the flipping base 1 is provided on the mounting port 500. The limiting part 501 is also provided with a chute matching the slide groove 14. The slide groove 14 and the chute are combined to form a rotating hole that limits the rotation shaft 200. The limiting part 501 is used to limit the flipping box through mutual cooperation with the flipping base 1. At each end of the limiting part 501, there is a threaded part 502 that matches the nut post 12 of the flipping base 1. The threaded part 502 is used to be threadedly connected to the nut post 12 by bolts.

[0041] Assembly principle: First, button 4 is soldered to the corresponding contact of circuit board 3 via pins, and circuit board 3 is fixed inside the main body 20 of button box 2. Then, bottom cover 21 is locked to main body 20 with bolts, and wires are led out through wire holes. Next, the rotating shaft 200 of button box 2 is embedded into the sliding groove 14 of flip base 1 to ensure that protrusion 15 and limit slot 201 are correctly matched. Finally, the nut post 12 of flip base 1 is fixed to the threaded part 502 of nail lamp upper shell 50 with bolts to complete the installation. In actual use, the user can achieve the flip operation by pushing the surface of button box. When button box is rotated to 90°, the protrusion of flip base contacts the end of limit slot, preventing further rotation. At this time, the button is in the most easy-to-operate state. In the non-working state, button box can be flipped to fit the surface of nail lamp, and bottom cover and upper shell form a flat appearance to avoid accidental contact with foreign objects. After the wire passes through the wire groove and wire hole, it is wrapped with corrugated tube and fixed inside the nail lamp to prevent breakage due to pulling during the flipping process.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
