Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, and in particular to a flip-type blade hair clipper. Background Technology

[0002] Hair clippers are tools used to trim hair and are widely used in the hairdressing industry. The clipper head is the key component of a hair clipper that is directly used to trim hair. The clipper head usually consists of two rows of overlapping, bladed teeth. The upper row of teeth is called the moving blade, and the lower row of teeth is called the stationary blade. During use, the stationary blade is stationary, while the moving blade is driven by the clipper's motor to quickly reciprocate, thereby cutting the hair. Powered by batteries or plug-in electricity, it is easy to operate, highly efficient, and can quickly trim large amounts of hair.

[0003] Chinese Patent Publication No. CN219617826U relates to the field of hair trimming technology, specifically a flip-type hair clipper. It includes a clipper body with a blade groove at one end, a blade head disposed within the groove, a rotating ring groove at the end of the clipper body near the blade groove, a first rotating ring within the rotating ring groove, and an anti-slip texture on the outer surface of the first rotating ring. A detachable base is located at the end of the clipper body away from the blade groove, and a charging port is located at the end of the detachable base away from the clipper body. A display screen is located at the end of the clipper body near the detachable base, and a start button is located between the display screen and the rotating ring groove. This allows the blade head to be flipped and fixed at any angle, facilitating cleaning of the blade head and blade groove.

[0004] For existing flip-type hair clippers, adjusting the blade angle is inconvenient during actual use. It requires the use of both hands or other auxiliary tools to adjust the blade angle, which affects the efficiency of adjustment. Furthermore, it is inconvenient to determine the blade angle after adjustment, which affects the subsequent haircutting effect. In addition, during use after adjustment, it is easily affected by vibration, which also affects the haircutting effect. Utility Model Content

[0005] The purpose of this invention is to provide a flip-type hair clipper that solves the problems in the prior art where the blade is inconvenient to adjust, affecting efficiency, and the blade is unstable after adjustment, which easily affects the haircutting effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flip-type hair clipper includes a blade head, a handle at the bottom of the blade head, two support rods fixedly connected to the top of the handle, an arc-shaped auxiliary plate fixedly connected to the top of the handle, an arc-shaped anti-jamming plate fixedly connected to the bottom of the blade head, a rotating shaft fixedly connected to the surface of the blade head, the rotating shaft being rotatably connected to the support rods, a half gear fixedly connected to the surface of the rotating shaft, a limiting half wheel fixedly connected to the surface of the half gear, a limiting mechanism between the surface of the support rods and the limiting half wheel, and a driving mechanism between the surface of the support rods and the half gears.

[0007] Preferably, the limiting mechanism includes an L-shaped limiting rod rotatably connected to the surface of the support rod, and the surface of the limiting half wheel is provided with a plurality of arc-shaped limiting grooves, with one end of the limiting rod located inside an adjacent limiting groove.

[0008] Preferably, the surface of the limiting rod and the side of the support rod are elastically connected by a compression spring.

[0009] Preferably, the drive mechanism includes an extension rod fixedly connected to the surface of the support rod, and a drive gear is rotatably connected to the surface of the extension rod.

[0010] Preferably, a knob is fixedly connected to the side of the drive gear near the extension rod.

[0011] Preferably, the top of the auxiliary plate has two anti-detachment grooves, the bottom of the anti-jamming plate is rotatably connected to two anti-detachment rods, the inside of the anti-detachment grooves is slidably connected to an anti-detachment block, and the free end of the anti-detachment rod is rotatably connected to the adjacent anti-detachment block.

[0012] This utility model has the following beneficial effects: When using hair clippers to cut hair, if the angle of the blade head needs to be adjusted for easier cutting, you can use one finger to apply force to the limiting rod to release the restriction on the blade head, and then use another finger to apply force to the knob to adjust the angle of the blade head. After adjustment, release the limiting rod, and the limiting rod will reset and restrict the blade head again by the elastic force of the compression spring, thus facilitating hair cutting. When the blade head rotates, the auxiliary plate and anti-jamming plate ensure smooth rotation without getting stuck. The two sides of the anti-jamming plate fit against the inner side of the support rod, increasing stability through friction during rotation. The angle of the blade head can be adjusted with only one hand, and the adjusted angle can be easily fixed for subsequent hair cutting. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-6A flip-type hair clipper includes a blade head 2, which is the main body of existing hair clippers. In use, the power supply to the main body of the blade head 2 is turned on, enabling the blade head 2 to start cutting hair. A handle 1 is located at the bottom of the blade head 2, allowing for convenient operation of the blade head 2 for hair cutting. Two support rods 3 are fixedly connected to the top of the handle 1, and an arc-shaped auxiliary plate 4 is fixedly connected to the top of the handle 1. An arc-shaped anti-jamming plate 13 is fixedly connected to the bottom of the blade head 2. The anti-jamming plate 13 and the auxiliary plate 4 ensure rotation... For smooth operation, the anti-jamming plate 13 is fitted against the inner side of the support rod 3 on both sides, which increases stability through friction during rotation. The blade head 2 needs to rotate via the support rod 3 during haircutting, allowing the blade on the blade head 2 to be easily used for haircutting at different angles and in different postures. A rotating shaft 5 is fixedly connected to the surface of the blade head 2, and the rotating shaft 5 is rotatably connected to the support rod 3. When it is necessary to rotate the blade head 2, the rotation of the rotating shaft 5 on the support rod 3 can easily drive the blade head 2 to rotate on the support rod 3. This allows the blade head 2 and handle 1 to rotate. A half gear 6 is fixedly connected to the surface of the rotating shaft 5, and a limiting half wheel 7 is fixedly connected to the surface of the half gear 6. The half gear 6 and the limiting half wheel 7 form a circular wheel that can rotate with the rotation of the rotating shaft 5. A limiting mechanism 8 is provided between the surface of the support rod 3 and the limiting half wheel 7. After the rotation of the blade head 2 is adjusted, the limiting mechanism 8 can conveniently restrict the limiting half wheel 7, preventing it from rotating and thus preventing the blade head 2 from rotating. After the blade head 2 is adjusted, the angle of the blade head 2 is stabilized for easy use. A driving mechanism 9 is provided between the surface of the support rod 3 and the half gear 6. When the driving mechanism 9 needs to drive the half gear 6, it allows the half gear 6 to rotate, ensuring that the blade head 2 can rotate to adjust its angle. The half gear 6 and the limiting half wheel 7 are on a circular wheel, which allows the distance between the limiting and driving mechanisms to be close. When the angle of the blade head 2 needs to be adjusted, it can be easily done with one hand, thereby improving the efficiency of the adjustment and preventing situations where the other hand is occupied and it is inconvenient to adjust the angle of the blade head 2.

[0018] Furthermore, the limiting mechanism 8 includes an L-shaped limiting rod 801 rotatably connected to the surface of the support rod 3. The surface of the limiting half-wheel 7 is provided with several arc-shaped limiting grooves 802. One end of the limiting rod 801 is located inside the adjacent limiting groove 802. Before rotating the angle of the blade head 2, the limiting rod 801 needs to be rotated first so that the limiting rod 801 can disengage from the inside of the limiting groove 802. Then, the limiting half-wheel 7 is driven to rotate by the half gear 6. After the angle of the half gear 6 is adjusted, the limiting rod 801 is rotated so that the limiting rod 801 can enter the adjacent limiting groove 802, locking the limiting half-wheel 7 so that the limiting half-wheel 7 cannot rotate. This prevents the rotating shaft 5 from rotating and driving the blade head 2 to rotate, ensuring that the blade head 2 can be used stably after the angle is adjusted, and will not shake after adjustment, affecting the accuracy of haircutting.

[0019] Furthermore, the surface of the limiting rod 801 is elastically connected to the side of the support rod 3 by a compression spring 803. The limiting rod 801 can rotate towards the limiting half-wheel 7 due to the elasticity of the compression spring 803. Before adjusting the angle of the blade head 2, the limiting rod 801 needs to be pulled first. After adjusting the angle, the limiting rod 801 is released, and the limiting rod 801 can rotate towards the limiting groove 802 due to the elasticity of the compression spring 803. Then, the limiting half-wheel 7 is finely adjusted by the drive mechanism 9 so that the limiting rod 801 can enter the interior of the adjacent limiting groove 802 to ensure stable use after the angle of the blade head 2 is adjusted, and the blade head 2 will not shake and affect hair cutting.

[0020] Furthermore, the drive mechanism 9 includes an extension rod 901 fixedly connected to the surface of the support rod 3. A drive gear 902 is rotatably connected to the surface of the extension rod 901. The drive gear 902 meshes with the teeth on the half gear 6. When the drive gear 902 rotates, it can drive the half gear 6 to rotate. When it is necessary to rotate the half gear 6, the drive gear 902 on the extension rod 901 can be rotated to drive the half gear 6 to rotate, so that the rotating shaft 5 can drive the cutter head 2 to rotate and adjust the angle.

[0021] Furthermore, a knob 903 is fixedly connected to the side of the drive gear 902 near the extension rod 901. When it is necessary to rotate the drive gear 902, force can be easily applied through the knob 903 to drive the drive gear 902 to rotate. The knob 903 is cylindrical and has anti-slip texture on its surface. Force can be easily applied through the fingers to the knob 903 to make the drive gear 902 rotate, thereby driving the half gear 6 to rotate.

[0022] Furthermore, the top of the auxiliary plate 4 has two anti-detachment grooves 10, and the bottom of the anti-jamming plate 13 is rotatably connected to two anti-detachment rods 11. An anti-detachment block 12 is slidably connected inside the anti-detachment groove 10. The free end of the anti-detachment rod 11 is rotatably connected to the adjacent anti-detachment block 12. When the anti-jamming plate 13 rotates with the blade head 2, it can drive the anti-detachment rod 11 to move. The anti-detachment rod 11 can drive the bottom of the anti-detachment block 12 to rise and fall inside the anti-detachment groove 10. The anti-detachment rod 11 can limit the rotation angle of the anti-jamming plate 13 to prevent the blade head 2 on the anti-jamming plate 13 from rotating too far and causing damage. The anti-detachment block 12 can rise and slide inside the anti-detachment groove 10, but cannot completely detach from the anti-detachment groove 10, so that the anti-detachment rod 11 can be driven by the anti-jamming plate 13 while limiting the rotation angle of the anti-jamming plate 13.

[0023] In summary: When using hair clippers for a haircut, the blade head 2 is activated, and then the handle 1 is held for the haircut. During the haircut, if the angle of the blade head 2 needs to be adjusted to accommodate different hand positions and haircut angles, force can be applied to the limiting rod 801 with one finger, causing the limiting rod 801 to rotate away from the limiting groove 802, thus releasing the limiting rod 801 from the limiting half-wheel 7. Then, force is applied to the knob 903, causing the drive gear 902 on the extension rod 901 to rotate. The knob 903 also rotates with the extension rod 901. After the drive gear 902 rotates, it can easily drive the half gear 6 to rotate, which in turn drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 on the support rod 3 allows the blade head 2 to adjust its angle accordingly. After the angle is adjusted, the restriction on the limiting rod 801 is released, and the limiting rod 801 is released by the elastic force of the compression spring 803. The blade head 2 rotates into the adjacent limiting groove 802, thereby fixing the position of the limiting half-wheel 7. This fixes the adjusted position of the blade head 2, allowing for continued haircutting. During the rotation and angle adjustment of the blade head 2, the anti-jamming plate 13 slides above the auxiliary plate 4. The anti-jamming plate 13 and the auxiliary plate 4 determine the rotation amplitude, ensuring the stability of the rotation process and preventing it from getting stuck and affecting rotation. During this process, the anti-detachment rod 11 at the bottom of the anti-jamming plate 13 allows the anti-detachment block 12 inside the anti-detachment groove 10 to move up and down. The anti-detachment block 12 can limit the rotation angle of the blade head 2 through the anti-detachment rod 11, preventing the blade head 2 from over-rotating and causing damage, thus ensuring the safety of the blade head 2. Through the above mechanism, when the blade head 2 needs to be used, the angle of the blade head 2 can be easily adjusted, making it convenient to use different postures and haircutting angles for haircutting, improving the convenience and efficiency of haircutting.
