Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, and in particular to a hair clipper with adjustable angle of the limiting comb. Background Technology

[0002] Electric hair clippers are used for trimming hair, and the limiting comb teeth, as an accessory of electric hair clippers, can not only separate the blade head from the skin to prevent the skin from being cut by the blade head, but also control the length of the haircut by the distance between the comb teeth and the blade head.

[0003] Traditional hair clippers control the length of haircuts by directly changing different comb teeth. Modern hair clippers, however, feature comb teeth that are movably mounted on the blades. These comb teeth can slide and adjust along the length of the clippers, thus changing the distance between the comb teeth and the blades. Taking Chinese utility model patent application number 202320575884.8 as an example, it discloses a comb teeth with an adjustable tooth mechanism and a hair clipper with comb teeth. The comb teeth are detachably connected to one end of a sliding bracket installed inside the housing. The other end of the sliding bracket meshes with an adjusting wheel. When the adjusting wheel rotates under external force, it simultaneously moves the sliding bracket back and forth along the housing axis, increasing or decreasing the distance between the end faces of the comb teeth and the end faces of the clipper blades. This utility model adjusts the distance between the end faces of the comb teeth and the end faces of the clipper blades by moving the sliding bracket back and forth along the housing axis.

[0004] In this utility model, since the end face of the trimmer head is conventionally inclined to the shell, and the direction of movement of the comb teeth is the axial direction of the shell, the end face of the comb teeth moves back and forth along the axial direction of the shell, rather than moving closer or further away directly along the radial direction of the trimmer head. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The problem to be solved by this utility model is to provide a hair clipper with adjustable angled positioning comb. One end of the drive plate is provided with a spring that can be elastically deformed. The spring slides in the inclined groove, which directly drives the positioning comb to move closer to or away from the fixed blade, thereby overcoming the defects in the prior art.

[0007] (II) Technical Solution

[0008] To solve the aforementioned technical problem, this utility model provides a hair clipper with an adjustable angled positioning comb, comprising:

[0009] A bracket is placed inside the housing of a hair clipper; a fixed blade and a limiting comb that can move closer to or further away from the fixed blade are installed at the front end of the bracket; an inclined sliding groove is provided at the front end of the bracket, and the inclined sliding groove faces the end face of the fixed blade.

[0010] An adjustment mechanism, mounted on the bracket, includes a drive plate that can slide relative to the bracket. The drive plate is provided with an elastically deformable spring piece, which slides within the inclined groove. The limiting comb is connected to the spring piece.

[0011] During use, the drive plate slides, and the spring sheet slides and extends within the inclined groove, causing the limiting comb to move closer to or further away from the fixed blade along the sliding direction of the inclined groove.

[0012] In this design, the inclined slide is tilted to the X-axis of the support and faces directly toward the limiting comb and the fixed blade. Therefore, it can directly drive the limiting comb to move closer to or further away from the fixed blade in the radial direction of the fixed blade end face. The drive plate slides along the X-axis of the support. Through the elastic deformation of the spring sheet of the drive plate, the sliding of the drive plate in the X-axis direction can be directly converted into sliding on the inclined slide. Therefore, it can directly drive the limiting comb to slide along the sliding direction of the inclined slide, that is, it can directly realize the movement of the limiting comb in the radial direction of the fixed blade end face.

[0013] In some embodiments, the adjustment mechanism includes a knob rotatably mounted on the bracket, which allows the drive plate to slide. In this design, power is transmitted to the drive plate by rotating the knob, while the positioning comb can move directly in the radial direction relative to the end face of the fixed blade. Therefore, compared to existing hair clipper positioning comb adjustment mechanisms, the displacement between the positioning comb and the fixed blade is greater in this design under the same knob rotation stroke.

[0014] In some embodiments, the bracket is slidably mounted with a self-locking member for locking the knob, the outer peripheral surface of the knob is provided with self-locking teeth, and the self-locking member is provided with a self-locking flange that can lock and engage with the self-locking teeth.

[0015] In this design, the self-locking component is used to lock the knob in place to prevent it from rotating during use. This is achieved by inserting a self-locking flange into the self-locking teeth of the knob.

[0016] In some embodiments, a positioning seat is mounted on the bracket, the knob is rotatable relative to the positioning seat, a stop pin is movably disposed on the positioning seat, and a stop tooth is correspondingly disposed on the inner sidewall of the knob.

[0017] In this design, a spring is installed inside the gear shift pin, so that the gear shift pin always moves toward the side that passes through the gear shift teeth. After rotating the knob, the gear shift pin will fall into the corresponding gear shift teeth.

[0018] In some embodiments, the knob includes a knob base and an outer ring and an inner ring that fasten to the knob base; the gear teeth are disposed within the inner ring.

[0019] In this design, the outer ring is knurled or frosted for direct contact with the user's fingers; the inner ring is located below the positioning seat in the axial direction, which can limit the displacement of the inner ring in the axial direction; both the outer and inner rings are fastened to the knob seat, and rotating the outer ring drives the inner ring to rotate.

[0020] In some embodiments, the knob is provided with a first gear, and the drive plate is provided with a rack, wherein the first gear transmits power to the rack through gear transmission;

[0021] The first gear meshes directly with the rack; or, the first gear meshes with the rack in sequence through the second gear and the double gear.

[0022] In some embodiments, a connecting post is provided on the inner side of the limiting comb, and the spring piece is fastened to the connecting post; the connecting post is provided with a slot, and the end of the spring piece is formed with a positioning post that cooperates with the slot.

[0023] In this design, the spring and the limiting comb are detachably fitted together, and the spring is positioned by being engaged with the positioning post of the limiting comb in the slot of the connecting post.

[0024] In some embodiments, the inclined slide groove is preferably perpendicular to the end face of the fixed blade, that is, the center line of the inclined slide groove is preferably perpendicular to the end face of the fixed blade. And / or, the angle between the inclined slide groove and the bracket is 110 degrees to 180 degrees.

[0025] In some embodiments, the self-locking component includes a push button slider slidably mounted on the housing and a push button for operation, the self-locking flange being disposed on the push button slider; and an arc-shaped transition groove is also provided at the upper end of the inclined slide groove.

[0026] In this design, the push button is exposed outside the housing. By pushing the push button, the self-locking flange and the self-locking teeth cooperate to form the self-locking of the knob. The arc-shaped transition groove is used to guide the spring of the transition drive plate into the inclined slide groove, which can avoid jamming and other phenomena to a certain extent.

[0027] In another embodiment, the hair clippers include:

[0028] A bracket is placed inside the housing of a hair clipper; a fixed blade and a limiting comb that can move closer to or further away from the fixed blade are installed at the front end of the bracket; an inclined sliding groove is provided at the front end of the bracket, and the inclined sliding groove faces the end face of the fixed blade.

[0029] An adjustment mechanism, mounted on the bracket, includes a drive plate that can slide relative to the bracket and a slider that is slidably placed in the inclined groove. The drive plate is connected to the slider via a crank connecting rod, and the limiting comb is connected to the slider.

[0030] In use, the drive plate slides, and the crank connecting rod drives the slider to extend and retract within the inclined groove, thereby causing the limiting comb to move closer to or further away from the fixed blade along the sliding direction of the inclined groove.

[0031] In this scheme, the drive plate of the adjustment mechanism drives the slider and the limiting comb to slide in the inclined groove through the crank-slider mechanism, thereby realizing that the limiting comb moves closer or further away from the fixed knife.

[0032] (III) Beneficial Effects

[0033] This utility model provides a hair clipper with an adjustable angled positioning comb. It features an inclined sliding groove that extends directly towards the fixed blade end face. The adjustment mechanism utilizes a deformable spring piece at one end of the drive plate. This spring piece slides within the inclined sliding groove, directly moving the positioning comb closer to or further away from the fixed blade along the sliding direction of the groove, thus making the adjustment of the distance between the positioning comb and the fixed blade end face more efficient. This utility model also includes a self-locking component for locking the knob, achieved by pushing the self-locking flange of the push knob to engage with the self-locking teeth of the knob. The spring piece and the connecting post of the positioning comb are detachably connected, with the positioning post of the spring piece engaging in a slot within the connecting post of the positioning comb for positioning. The knob adjustment method provides convenient adjustment. Attached Figure Description

[0054] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0055] See Figures 1-3This utility model provides a hair clipper with an adjustable limiting comb, comprising: a support 1, a fixed blade 2, a limiting comb 3, and an adjustment mechanism. The fixed blade 2 is installed at the front end of the support 1, and the limiting comb 3 can move closer to or further away from the fixed blade 2. The front end of the support 1 is provided with an inclined sliding groove 101, which faces the end face of the fixed blade 2. The adjustment mechanism is installed on the support 1 and specifically includes a drive plate 4 that can slide relative to the support 1. The drive plate 4 is provided with an elastically deformable spring piece 401, which slides within the inclined sliding groove 101. The limiting comb 3 is connected to the spring piece 401. In use, the drive plate 4 slides, and the spring piece 401 slides and extends within the inclined sliding groove 101, causing the limiting comb 3 to move closer to or further away from the fixed blade 2 along the sliding direction of the inclined sliding groove 101.

[0056] It should be noted that in this embodiment, the drive plate 4 slides along the X-axis of the bracket 1, while the inclined slide groove 101 is inclined to the X-axis of the bracket 1. The inclined slide groove 101 is directly facing the limiting comb 3 and the fixed knife 2. Through the elastic deformation of the spring piece 401 of the drive plate 4, the sliding of the drive plate 4 in the X-axis direction can be directly converted into sliding on the inclined slide groove 101. Therefore, the limiting comb 3 can be directly driven to slide along the sliding direction of the inclined slide groove 101, that is, the limiting comb 3 can be directly moved in the radial direction along the end face of the fixed knife 2.

[0057] like Figure 1 and Figure 2 As shown, the shell includes an upper shell (not shown in the figure) and a lower shell 9.

[0058] In a preferred embodiment, the inclined groove 101 is preferably arranged perpendicularly to the end face of the fixed blade 2, and the limiting comb 3 moves closer to or further away from the end face of the fixed blade 2 in a direction perpendicular to the end face of the fixed blade 2.

[0059] See Figures 1-3 In some embodiments, the adjustment mechanism includes a knob 5 rotatably mounted on the bracket 1, which allows the drive plate 4 to slide. In this solution, power is transmitted to the drive plate 4 by rotating the knob 5, and the limiting comb can move directly in the radial direction relative to the end face of the fixed blade. Therefore, compared with the existing hair clipper limiting comb adjustment mechanism, the displacement between the limiting comb and the fixed blade 2 is greater in this solution under the same rotation stroke of the knob 5.

[0060] In some embodiments, such as Figure 1 , Figure 2 and Figure 12 As shown, the bracket 1 is slidably equipped with a self-locking element 6 for locking the knob 5. The self-locking element 6 is used to lock the knob 5 to prevent it from rotating during use; as shown Figure 7 and Figure 10As shown, self-locking teeth 502 are distributed on the outer peripheral surface of the knob 5, and the self-locking member 6 is provided with a self-locking flange 601 that can lock and engage with the self-locking teeth 502. The self-locking of the knob 5 is achieved by inserting the self-locking flange 601 into the self-locking teeth 502.

[0061] In some embodiments, such as Figure 2 , Figure 5 , Figure 10 and Figure 11 As shown, a positioning seat 102 is mounted on the bracket 1, and the knob 5 can rotate relative to the positioning seat 102. A stop pin 103 is movably mounted on the positioning seat 102, and a spring is provided inside the stop pin 103; Figure 11 As shown, the inner wall of knob 5 is provided with corresponding gear teeth 503; as Figure 5 As shown, the gear pin 103 is pushed into the gear tooth 503 by the spring on its inner side; the knob 5 includes a knob seat 504 and an outer ring 505 and an inner ring 506 that are fastened to the knob seat 504; the gear tooth 503 is disposed in the inner ring 506.

[0062] In this embodiment, the outer ring is knurled or frosted; such as... Figure 5 As shown, the inner ring 506 is located below the positioning seat 102 in the axial direction, which can limit the displacement of the inner ring 506 in the axial direction; both the outer ring 505 and the inner ring 506 are fastened to the knob seat 504, and the inner ring 506 is rotated by rotating the outer ring 505.

[0063] In some embodiments, a first gear 501 is provided on the knob 5, and a rack 402 is provided on the drive plate 4. The first gear 501 transmits power to the rack 402 through gear transmission.

[0064] In one example, such as Figure 2 and Figure 6 As shown, the first gear 501 meshes with the rack 402 in sequence through the second gear 7 and the double gear 8.

[0065] It should be noted that in other embodiments, the first gear 501 can also directly mesh with the rack 402, and the drive plate 4 can be driven to slide by the rotation of the knob 5 and the direct meshing of the first gear 501 and the rack 402.

[0066] In some embodiments, such as Figure 2 , Figure 8 and Figure 9 As shown, a connecting post 301 is provided on the inner side of the limiting comb 3, and the spring piece 401 is fastened to the connecting post 301.

[0067] like Figure 2 , Figure 8 and Figure 9As shown, in one example, the connecting post 301 is provided with a slot 302, and the end of the spring piece 401 is formed with a positioning post 403 that cooperates with the slot 302, so that the spring piece 401 and the limiting comb 3 form a detachable engagement, and the positioning is achieved by the positioning post 403 engaging in the slot 302 of the connecting post 301.

[0068] In some embodiments, such as Figure 12 As shown, the self-locking component 6 includes a push-button slider 602 slidably mounted on the housing 1 and a push button 603 for operation, with a self-locking flange 601 disposed on the push-button slider 602. By pushing the push button 603, the self-locking flange 601 engages with the self-locking teeth 502 to form the self-locking mechanism of the knob 5.

[0069] In some embodiments, such as Figure 4 As shown, an arc-shaped transition groove 104 is also provided at the upper end of the inclined slide groove 101. The arc-shaped transition groove 104 is used to guide the spring piece 401 of the transition drive plate 4 into the inclined slide groove 101.

[0070] In some embodiments, such as 3 and Figure 4 As shown, the angle between the inclined slide 101 and the bracket 1 is 110 to 180 degrees, that is, the angle between the center of the inclined slide 101 and the X-axis is 110-180 degrees, preferably 140 degrees.

[0071] like Figure 13 As shown in the embodiment of this specification, another type of hair clipper with an adjustable limiting comb is also provided, including: a bracket 1, a fixed blade 2, a limiting comb 3, and an adjustment mechanism. The bracket 1 is placed inside the housing of the hair clipper, and the fixed blade 2 is installed at the front end of the bracket 1. The limiting comb 3 can move closer to or further away from the fixed blade 2. An inclined sliding groove 101 is provided at the front end of the bracket 1, with the inclined sliding groove 101 facing the end face of the fixed blade 2. The adjustment mechanism is installed on the bracket 1 and specifically includes a drive plate 4 that can slide relative to the bracket 1 and a slider that slides in the inclined sliding groove 101. The drive plate 4 is connected to the slider through a crank connecting rod, and the limiting comb 3 is connected to the slider. In use, the drive plate 4 slides, and the crank connecting rod drives the slider to extend and retract within the inclined sliding groove 101, causing the limiting comb 3 to move closer to or further away from the fixed blade 2 along the sliding direction of the inclined sliding groove 101.

[0072] The difference between this embodiment and the previous embodiment is that in this embodiment, the drive plate 4 drives the slider to slide in the inclined groove 101 through the crank connecting rod, thereby driving the limiting comb 3 to move closer to or further away from the fixed knife 2.

[0073] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0074] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
