Technical Field

[0001] This utility model belongs to the field of electric hair clipper technology, and specifically refers to an adaptive hair clipper comb cover. Background Technology

[0002] Hair clippers, as common personal care and professional hair styling tools, are widely used in everyday home trimming and salon styling. The comb cap, as an auxiliary component, is mainly used to control the trimming length and protect the blades, playing a crucial role in safety and effectiveness.

[0003] However, most hair clipper caps on the market currently use a snap-on or embedded design, requiring precise matching with the slots, steps, and other structures of specific hair clipper models for installation. For example, hair clippers from different manufacturers vary in blade size, step position, and shape, resulting in a single cap only being compatible with one or a few models. This "one-to-one" compatibility not only increases the purchase cost and storage burden for users but also limits the versatility of hair clipper accessories. When consumers switch hair clipper brands or models, their original caps often become unusable, leading to resource waste and inconvenience. Utility Model Content

[0004] This invention achieves adaptive compatibility and quick assembly / disassembly for different models of hair clippers through an elastic fixing plate and a rotating locking mechanism, thus solving the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: an adaptive hair clipper comb cover, comprising:

[0006] The main body of the comb cover includes a base portion covering the hair clipper head and a comb tooth portion connected to the front end of the base portion;

[0007] The elastic fixing piece includes a hook end for locking the step of the hair clip, a fixing end detachably connected to the base portion, and an elastic portion connecting the hook end and the fixing end, the elastic portion being used to provide an elastic preload force that presses the hook end against the step.

[0008] A rotary locking mechanism is provided between the fixed end of the elastic fixing piece and the base of the comb cover body. The rotary locking mechanism is used to lock and separate the elastic fixing piece from the base through rotational movement.

[0009] The present invention is further configured such that the rotary locking mechanism includes:

[0010] A slider is disposed at the fixed end of the elastic fixing piece;

[0011] A slide rail is provided at the base of the comb cover body, and the end of the slide rail is connected to a rotating chamber;

[0012] The slider slides along the slide rail into the rotating chamber, and the elastic fixing piece is locked by rotation.

[0013] The present invention is further configured such that the inner wall of the rotating cavity is provided with a locking platform, and the side wall of the slider is provided with a locking groove that matches the locking platform.

[0014] The present invention is further configured such that the elastic portion of the elastic fixing piece consists of two symmetrically arranged W-shaped bent pieces.

[0015] The present invention is further configured such that the elastic part of the elastic fixing piece is made of any one of spring steel, titanium alloy or nickel-titanium shape memory alloy.

[0016] The present invention is further provided that the hook end is provided with a compensation pad for filling the gap between the steps through elastic deformation.

[0017] The present invention is further configured such that the compensation pad is a wedge-shaped structure, and its inclined surface is configured to form a progressive compression fit with the contact surface of the step gap.

[0018] The present invention is further configured such that a pressing member is provided on one side of the hook end of the elastic fixing piece, and the pressing member drives the hook end to disengage from the step by pressing.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0030] Example 1:

[0031] This embodiment provides an adaptive hair clipper comb cover, including:

[0032] The comb cover body 1 includes a base portion 10 covering the hair clipper head 2 and a comb tooth portion 11 connected to the front end of the base portion 10;

[0033] The elastic fixing piece 3 includes a hook end 30 for locking the hair clip step 4, a fixing end 31 detachably connected to the base part 10, and an elastic part 32 connecting the hook end 30 and the fixing end 31. The elastic part 32 is used to provide an elastic preload force that presses the hook end 30 against the step 4.

[0034] A rotating locking mechanism 5 is provided between the fixed end 31 of the elastic fixing piece 3 and the base portion 10 of the comb cover body 1. The rotating locking mechanism 5 is used to lock and separate the elastic fixing piece 3 from the base portion 10 through rotational movement.

[0035] The main body 1 of the comb cover serves as the basic structure of the hair clipper's comb cover, covering the blade head 2 and providing support for the comb teeth to control the length of hair trimming.

[0036] The base portion 10 provides a mounting base for the elastic fixing piece 3 and the comb portion 11, protecting the clipper head 2 from external impacts. The base portion 10 covers the clipper head 2 and is arranged parallel to the clipper head 2. The base portion 10 is generally a plate-like structure adapted to the contour of the clipper head 2, and is usually rectangular or elliptical.

[0037] The comb-like part 11 is used to comb the hair and control the trimming length, preventing the blade head 2 from directly contacting the skin. The comb-like part 11 can be fixed to the front end of the base part 10 by means of integral molding or other methods, corresponding to the comb-like part of the blade head 2. The comb-like part 11 is generally composed of multiple evenly spaced comb teeth.

[0038] The elastic fixing piece 3 fixes the comb cover body 1 to the hair clipper with elastic pre-tightening force and can be quickly removed.

[0039] The hook end 30 is used to engage with the step 4 of the hair clipper, and the compensation pad 8 fills the gap through elastic deformation to enhance stability. The hook end 30 is generally a hook-shaped structure adapted to the step 4 of the hair clipper. The hook end 30 is usually integrally molded with the elastic part 32.

[0040] The fixed end 31 is used to realize the detachable connection between the elastic fixing piece 3 and the base part 10. The fixed end 31 is generally a flat plate structure adapted to the surface of the base part 10, usually integrally formed with the elastic part 32, and can be detachably connected to the base part 10 by the rotation locking mechanism 5.

[0041] The elastic part 32 is used to provide elastic preload, so that the hook end 30 presses against the hair clipper step 4, adapting to different sizes. The elastic part 32 connects the hook end 30 and the fixed end 31, is located between the two, and the hook end 30 and the fixed end 31 are integrally formed, forming an integral structure through continuous material processing.

[0042] The rotary locking mechanism 5 achieves locking and separation of the elastic fixing plate 3 and the base part 10 through rotational movement.

[0043] The elastic preload of the elastic part 32 enables the hook end 30 to adaptively press against the steps 4 of different sizes. The rotary locking mechanism 5 achieves mechanical locking through rotational movement. The two work together to solve the problems of poor adaptability and cumbersome disassembly and assembly of traditional comb caps.

[0044] In this embodiment, when installing the comb cover body 1, the user can press the elastic part 32 of the elastic fixing piece 3 to make it elastically deform, align the hook end 30 with and snap it into the step 4 of the hair clipper. At this time, the elastic pre-tightening force of the elastic part 32 makes the hook end 30 continuously press against the step 4. Then, by rotating the locking mechanism 5, the elastic fixing piece 3 and the base part 10 are locked, thereby firmly connecting the elastic fixing piece 3 and the base part 10, completing the installation of the comb cover body 1 on the hair clipper. When disassembling, the locking mechanism 5 is rotated in the opposite direction to unlock the fixing end 31, and the hook end 30 is pressed to disengage it from the step 4, so that the comb cover body 1 can be removed from the hair clipper.

[0045] Example 2:

[0046] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The rotary locking mechanism 5 includes:

[0048] The slider 50 is located at the fixed end 31 of the elastic fixing piece 3;

[0049] A slide rail 51 is provided on the base portion 10 of the comb cover body 1, and the end of the slide rail 51 is connected to a rotating chamber 52;

[0050] The slider 50 slides along the slide rail 51 into the rotating chamber 52, and the elastic fixing piece 3 is locked by rotation.

[0051] The purpose of this embodiment is to achieve a quick and reliable connection between the elastic fixing piece 3 and the base part 10 through the synergistic effect of the slider 50, the slide rail 51 and the rotating chamber 52.

[0052] The slider 50 is generally a rectangular or T-shaped columnar protrusion, integrally formed with the fixed end 31 of the elastic fixing piece 3, and slides linearly along the matching groove slide rail 51 of the base part 10. The end of the slide rail 51 smoothly transitions to the rotating chamber 52 with an inner diameter slightly larger than that of the slider 50. The rotating chamber 52 can be cylindrical. When the slider 50 enters the rotating chamber 52, it can be rotated by 90° or other preset angles to make the side wall of the slider 50 abut against the end of the slide rail 51. Because the side wall of the slider 50 does not match the slide rail 51, the slider 50 cannot disengage from the slide rail 51 at this position, thus achieving the locking of the fixed end 31.

[0053] This design simplifies the cumbersome process of traditional buckles requiring multi-point alignment, and achieves mechanical locking through a single push-turn action, ultimately improving the convenience and stability of comb cap installation while ensuring structural compactness.

[0054] Example 3:

[0055] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] The inner wall of the rotating chamber 52 is provided with a locking platform 6, and the side wall of the slider 50 is provided with a locking groove 7 that matches the locking platform 6.

[0057] In this embodiment, the locking platform 6 on the inner wall of the rotating chamber 52 can be a radially protruding rectangular or semi-circular structure, and the locking groove 7 on the side wall of the slider 50 is a correspondingly shaped recessed groove, with the two shapes fitting together. When the slider 50 slides into the rotating chamber 52 along the slide rail 51, the locking platform 6 is inserted into the locking groove 7 by rotation, forming a mechanical locking structure with a convex-concave fit. The purpose is to restrict the movement of the slider 50 in the axial direction through the engagement of the locking platform 6 and the locking groove 7, thereby firmly locking the elastic fixing piece 3 on the base portion 10 of the comb cover body 1, preventing the elastic fixing piece 3 from loosening or falling off due to external forces such as vibration during the use of the hair clipper, ensuring the stability and reliability of the comb cover after installation. At the same time, the clear convex-concave fit also provides clear operational feedback to the user, making it easy to confirm the locking status.

[0058] Example 4:

[0059] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] The elastic part 32 of the elastic fixing piece 3 consists of two symmetrically arranged W-shaped bent pieces 320.

[0061] In this embodiment, the elastic part 32 of the elastic fixing piece 3 adopts two symmetrically arranged W-shaped bending pieces 320. The purpose of this design is to give the elastic fixing piece 3 stable and adjustable elastic deformation capability through a unique geometric shape and symmetrical structure. When subjected to force, the multiple bending segments of the W-shaped bending pieces 320 can be compressed or extended in concert, adapting to the size differences of different hair clipper steps 4 within a certain range, so that the hook end 30 always maintains the pressing force on the step 4; the symmetrical structure ensures that the force on both sides is balanced, avoiding the elastic fixing piece 3 from shifting or twisting during use, and ensuring the stability of the connection between the comb cover and the hair clipper; at the same time, this shape increases the deformation stroke of the elastic part 32, improves the elastic reserve without increasing the amount of material used, ensures the continuity of the pre-tightening force during long-term use, and effectively solves the problems of poor compatibility and easy loosening of traditional fixing methods.

[0062] Example 5:

[0063] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] The elastic part 32 of the elastic fixing piece 3 is made of any one of spring steel, titanium alloy or nickel-titanium shape memory alloy.

[0065] In this embodiment, the elastic part 32 of the elastic fixing piece 3 is made of any one of the following materials: spring steel, titanium alloy, or nickel-titanium shape memory alloy. Its design aims to leverage the unique mechanical and physical properties of these materials to ensure stable elastic deformation and structural reliability of the elastic fixing piece 3 during long-term use. Spring steel possesses high strength and excellent elastic recovery force, maintaining the preload of the elastic part 32 when the hook end 30 is frequently pressed, preventing the comb cap from loosening due to fatigue deformation. Titanium alloy combines lightweight and high corrosion resistance, reducing the overall weight of the comb cap while maintaining elasticity, and is suitable for use in humid environments. Nickel-titanium shape memory alloy can recover its initial shape after being deformed by external force through temperature or stress triggering, automatically resetting even under extreme external force and large deformation, significantly improving the damage resistance of the elastic part 32. All three types of materials possess good wear resistance and fatigue resistance, meeting the requirements of frequent pressing and long-term use of the elastic part 32, ensuring the stability and service life of the connection between the comb cap and the hair clipper from a material perspective.

[0066] Example 6:

[0067] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] The hook end 30 is provided with a compensation pad 8 for filling the gap of the step 4 through elastic deformation.

[0069] In this embodiment, a compensation pad 8 is provided on the hook end 30, which is designed to adaptively fill the gap between the hair clipper step 4 and the hook end 30 through its elastic deformation characteristics, thereby enhancing the stability of the comb cap connection. The compensation pad 8 can be designed as a hemispherical or cylindrical shape. This rounded structure can fully fit the surface of the step 4 at different angles, and tightly fill the gap through all-round elastic compression when under force. Alternatively, a thin sheet structure can be used to cover the main contact area between the hook end 30 and the step 4, relying on flexible deformation to fill tiny gaps. In terms of connection method, the compensation pad 8 can be integrally molded with the hook end 30 through injection molding to ensure a firm connection and no risk of falling off; it can also be glued with adhesive for easy quick assembly and replacement; or it can be an embedded design, embedding the compensation pad 8 into the groove reserved in the hook end 30, and achieving a detachable connection through interference fit or snap-fit ​​structure. In this way, no matter what differences there are in the size and shape of the hair clipper step 4, the compensation pad 8 can fit tightly with its own deformation, effectively eliminating installation gaps and preventing the comb cover from loosening, shifting or making noise due to vibration during use, thus greatly improving the compatibility and connection reliability between the comb cover and the hair clipper.

[0070] Example 7:

[0071] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] The compensation pad 8 has a wedge-shaped structure, and its inclined surface is configured to form a progressive compression fit with the contact surface of the gap between the steps 4.

[0073] In this embodiment, the compensation pad 8 adopts a wedge-shaped structure, and its inclined surface is designed to form a progressive pressing fit with the gap of the step 4. The purpose is to achieve dynamic adaptive fastening between the comb cap and the hair clipper through its unique geometry and force characteristics. When the hook end 30 of the elastic fixing piece 3 is engaged with the step 4 of the hair clipper, the wedge-shaped compensation pad 8 will be squeezed by the step 4. As the comb cap is further installed, the contact area between its inclined surface and the gap of the step 4 gradually increases, and the friction and pressing force generated also increase accordingly. This progressive pressing process can effectively fill the gap caused by the difference in the size of the steps 4 of different hair clippers, and when the hair clipper vibrates during operation, the pressure will increase with the increase of the vibration amplitude, forming a "self-locking" effect to prevent the comb cap from loosening or falling off. Compared with the ordinary planar structure compensation pad 8, the wedge-shaped design significantly improves the stability and compatibility of the comb cap installation, while simplifying the process of adapting to various hair clipper models.

[0074] Example 8:

[0075] This embodiment provides an adaptive hair clipper comb cover, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] The elastic fixing piece 3 has a pressing member 9 on one side of the hook end 30. The pressing member 9 drives the hook end 30 to disengage from the step 4 by pressing.

[0077] In this embodiment, a pressing element 9 is provided on one side of the hook end 30 of the elastic fixing piece 3, which aims to achieve quick disassembly of the comb cap through a convenient mechanical structure. The pressing element 9 is usually designed as a sheet-like or columnar protrusion structure, and the surface may have anti-slip texture or curvature to fit the ergonomic design of finger pressing, making it easy to apply force. In terms of connection, the pressing element 9 can be manufactured with the elastic fixing piece 3 using an integral molding process to ensure structural strength and reliability and avoid the risk of falling off due to long-term use; it can also be fixed to the side of the hook end 30 by means of buckles, screws or welding to ensure stable transmission of force when pressing. When the user presses this part, the pressing element 9 transmits the force to the hook end 30, using the lever principle or direct pushing force to drive the hook end 30 to deform, causing it to disengage from the hair clipper step 4. With the unlocking operation of the rotating locking mechanism 5, the comb cap can be easily removed, greatly improving the convenience and efficiency of disassembly and meeting the user's need for quick replacement of the comb cap.

[0078] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
