Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, and more specifically, to a limiting comb for a hair clipper. Background Technology

[0002] A hair clipper is an electric tool that uses a motor to drive the blades in a reciprocating or rotating motion to trim hair. It mainly consists of a blade, motor, housing, and power supply system (battery or power cord), and is widely used in professional hairdressing, home care, and pet grooming. Its core function is to replace manual haircuts with mechanical movement. Different types of blades (such as titanium alloy or ceramic blades) can be changed to suit various trimming needs, from very short buzz cuts to long curly hair. Some models also feature rounded blades designed for children to enhance safety.

[0003] A guide comb is a comb-like accessory installed on the outside of the clipper head. It is usually made of plastic and marked with clear length markings (such as 1mm, 3mm, 6mm). Its main functions include: physically limiting the distance between the clipper head and the scalp by the height of the comb teeth, avoiding uneven trimming length caused by manual operation, which is especially suitable for beginners to achieve standardized trimming; users do not need professional skills, they can simply select the guide comb with the corresponding marking to move along the scalp to complete an even trim, reducing the operation threshold; different sizes of guide combs can support a variety of hairstyle designs such as buzz cuts and gradients, and by using them in combination, they can also create a sense of layering or transition effects.

[0004] The current limiting comb only offers preset specifications such as 1mm, 3mm, and 6mm, which cannot meet the needs of fine lengths such as 4.5mm. Users need to replace the comb teeth or make manual adjustments multiple times, which is cumbersome and can easily lead to uneven hairstyling, especially affecting the aesthetics of children's hairstyles or gradient designs. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting comb for a hair clipper, which aims to solve the technical problems in the background art mentioned above.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This application provides a limiting comb for a hair clipper, comprising: a limiting comb body with a comb tooth structure; a connecting bracket for connecting the limiting comb body to the hair clipper and slidingly engaging with the limiting comb body to adjust the distance between the comb tooth structure and the hair clipper; and an adjusting component including a straight tooth structure, a gear, and an adjusting knob. The straight tooth structure is disposed on the connecting bracket, the gear meshes with the straight tooth structure, and the adjusting knob is rotatably disposed on the outer arm of the limiting comb body and connected to the gear to drive the gear to rotate. The limiting comb body and the adjusting knob have multiple circumferentially arranged slots at their rotation points. The adjusting knob is elastically connected to a positioning ring, and the positioning ring has a spherical connector for fitting into each of the multiple slots.

[0008] Furthermore, based on the aforementioned solution, the connecting bracket is provided with a protruding buckle for fitting into the concave groove of the hair clipper head.

[0009] Furthermore, based on the aforementioned scheme, a knob cover is provided on the outer wall of the adjustment knob, and the knob cover is provided with scale markings in the circumferential direction;

[0010] The aforementioned limiting comb body is provided with a starting mark portion for matching the aforementioned scale markings.

[0011] Furthermore, based on the aforementioned scheme, the aforementioned limiting comb body is provided with a mounting hole, and the aforementioned connecting bracket and the aforementioned adjusting knob are respectively provided at both ends of the aforementioned mounting hole;

[0012] The mounting hole has a positioning slot at one end facing the connecting bracket, and the adjustment knob has a plug structure that engages with the positioning slot.

[0013] Furthermore, based on the aforementioned scheme, the positioning ring and the adjustment knob are elastically connected by a spring.

[0014] Furthermore, based on the aforementioned scheme, the connecting bracket is provided with a guide groove, and the limiting comb body is provided with a guide slider that slides in cooperation with the guide groove.

[0015] Furthermore, based on the aforementioned scheme, the guide groove and the guide slider form a guide sliding structure, and the number of the guide sliding structures is two.

[0016] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0017] The limiting comb for the hair clipper described in this application works by adjusting a knob to drive a gear to rotate. The gear meshes with a straight tooth structure on the connecting bracket, converting the rotational motion of the knob into relative sliding between the connecting bracket and the limiting comb body. This allows for continuous adjustment of the distance between the comb teeth and the hair clipper blade. Simultaneously, multiple circumferentially arranged slots on the limiting comb body and the rotating part of the adjusting knob, along with a positioning ring and a spherical connector that are elastically connected to the adjusting knob, allow for positioning and locking after the target distance is reached by engaging the spherical connector with the corresponding slot. The advantages of this structure are as follows: Firstly, it breaks through the limitations of traditional fixed-position combs, allowing for stepless fine-tuning of the spacing (e.g., 0.5mm precision) through the precise engagement of gears and straight teeth, meeting the requirements for fine lengths such as 4.5mm, and avoiding the cumbersome operation and uneven haircut caused by multiple comb changes or manual adjustments. Secondly, the matching structure of the positioning ring, the spherical connector, and the groove can form a reliable mechanical lock after adjustment, preventing spacing displacement due to vibration or external force during trimming. This is more stable than traditional snap-fit ​​fixing, and the elastically connected spherical connector can achieve "click-like" positioning feedback, allowing users to intuitively perceive the adjustment position and improving operational convenience and precision reliability.

Through the precise docking of the plug and the positioning slot 17, it is ensured that the transmission components (such as gear 4 and spur gear structure 3) of the adjusting knob 6 and the connecting bracket 5 maintain coaxiality during installation, avoiding adjustment jamming or transmission failure caused by assembly deviation. At the same time, it simplifies the disassembly and assembly process and improves the stability and assembly efficiency of the overall structure of the limiting comb.

[0038] In a preferred embodiment, the positioning ring 13 and the adjustment knob 6 are elastically connected by a spring 15.

[0039] In the above embodiment, the positioning ring 13 and the adjustment knob 6 are elastically connected by a spring 15, which allows the spherical connector 18 on the positioning ring 13 to automatically adapt to the undulations of the slot 10 during the rotation of the adjustment knob 6, ensuring that the spherical connector 18 can stably fit into any slot 10 to achieve positioning and locking.

[0040] In a preferred embodiment, the connecting bracket 5 is provided with a guide groove 16, and the limiting comb body 1 is provided with a guide slider 12 that slides in cooperation with the guide groove 16.

[0041] In the above embodiment, the connecting bracket 5 is provided with a guide groove 16, and the limiting comb body 1 is provided with a guide slider 12 that slides with it. Through the precise guidance of the groove and the slider, it can be ensured that the limiting comb body 1 slides smoothly in a fixed direction when adjusting the spacing, avoiding adjustment accuracy errors caused by shaking or deviation.
