Description

Technical Field

[0001] The utility model relates to the technical field of hairdressing equipment, in particular to an electric hair clipper with an adjustable comb cover. Background Art

[0002] Hairdressing is the most common beauty behavior for everyone. It not only occurs frequently, but also meets a variety of aesthetic and practical needs. Electric clippers, as hairdressing tools, are undoubtedly the most widely used.

[0003] The length of haircut is one of the most basic requirements of haircut. Initially, only professional barbers could control it well in the barber industry. However, with the improvement and development of haircut tools, non-professionals also perform corresponding operations. For example, some electric clippers are equipped with a device to automatically adjust the length of haircut, which solves the problem of pre-setting the length of hair for adjustment during trimming. However, it also faces problems such as troublesome adjustment or unstable limit. Different haircut lengths can be achieved by installing limit combs of different hair lengths, but there are also problems such as too many types of limit combs and troublesome disassembly and assembly.

[0004] In order to solve the above problems, a technical solution for adjusting the length of haircut by adjusting the distance between the comb cover and the blade has emerged. In order to prevent the distance between the comb cover and the blade from changing during the haircut process, a technical solution for locking and unlocking the adjustment mechanism has also emerged. For example, CN209364686U discloses an electric hair clipper with an adjustable comb row. Its locking technical solution is to set a locking switch that can be toggled back and forth to achieve the purpose of locking and unlocking the adjustment mechanism. However, in order for the thumb to apply effective push and pull force to the switch each time, the hand must change the grip of the electric hair clipper, which is not very convenient and may even cause the electric hair clipper to slip out of the hand accidentally. In addition, in places where the electric hair clipper is used frequently, the thumb repeatedly toggles the switch many times, causing finger fatigue and even soft tissue contusion. Improvements are urgently needed to address the above problems. Utility Model Content

[0049] As Figures 2 to 12As shown, the bracket 32 ​​includes a bottom plate 320 for fixing inside the fuselage 1, a positioning ring 321 is provided on the bottom plate 320, a first locking tooth 322 and a center plate 323 are provided on the bottom plate 320 inside the positioning ring 321, the center plate 323 and the bottom plate 320 are connected as a whole through the first locking tooth 322, and a through hole 324 is provided between the center plate 323 and the bottom plate 320, the through hole 324 can be used for the adjustment gear 33 to move back and forth, and a guide column 325 and a retaining block 326 are provided on the center plate 323, and the guide column 325 (axial guide rod) and the retaining block 326 are distributed correspondingly to each other. After the locking device 4 is activated, the locking device 4 is meshed with the first locking tooth 322 and the adjustment gear 33 for use, and the button is pressed. When the locking device 4 is in the downward direction, in addition to meshing with the adjusting gear 33, the locking device 4 also meshes with the first locking tooth 322. Such a configuration improves the stress condition of the guide column 325 and increases the locking strength. A hook 327 is provided on the center plate 323 at the position of the retaining block 326. The hook 327 is used in conjunction with the locking device 4. The hook 327 includes a hanging rod 3271 and a rotating shaft 3272 arranged at the lower end of the hanging rod 3271. A hook 3273 is provided at the upper end of the hanging rod 3271. The rotating shaft 3272 and the hook 3273 are both perpendicular to the hanging rod 3271. The rotating shaft 3272 can be rotatably assembled on the lower center part of the center plate 323. The hook is hung in the locking device 4. The retaining block 326 can prevent the hook of the hook 327 from detaching from the locking device 4. It is further explained that the location of the positioning ring 321 is provided with a node spring 328 and a node ball 329, and the node spring 328 is used to push the node ball 329, and the node ball 329 cooperates with the adjustment disk 34. It is further explained that the first locking tooth 322 is provided with a guide slope on both sides, and the guide slope is in an inverted "V" shape, so that when the locking operation is performed, the locking device 4 can mesh smoothly with the adjustment gear 33 and the first locking tooth 322, and will not be mutually opposed or stuck. Finally, it is also emphasized that the lower surface of the center plate 323 is provided with a mounting hole 3231 for mounting the upper shaft of the hook 327, and this arrangement is conducive to the installation of the hook 327.

[0050] like Figures 2 to 12The second locking tooth 333 is located in the through hole 324, and the lower end surface of the main body 331 is provided with a driving gear 334 which meshes with the rack 313. The adjusting disk 34 is provided with an arc-shaped female connecting block 343, and the arc-shaped female connecting block 343 matches the male connecting block 332 for wrapping and assembling. In this way, the linear motion of the adjusting member 31 is driven by the rotation of the adjusting gear 33, and the adjusting disk 34 is rotated to drive the adjusting gear 33 to rotate synchronously. The adjusting gear 33 drives the adjusting member 31 provided with the rack 313 to move axially along the body 1. The adjusting member 31 drives the comb set 2 to move away from or approach the cutter head along the driving protrusion through its driving rod 314, thereby realizing the hair cutting length adjustment. The comb set 2 is driven by the gear and rack method, which is simple and reliable. Further explanation, the outer side of the male connection block 332 is arc-shaped, which is more conducive to the use with the adjustment disk 34. Further explanation, guide slopes are provided above the two sides of the second locking tooth 333, and the guide slopes are in an inverted "V" shape. Such a setting enables the locking device 4 to mesh smoothly with the first locking tooth 322 and the second locking tooth 333 during the locking operation, so as not to be stuck or stuck against each other. When the locking device 4 of the utility model is pressed down, the locking device 4 meshes with the second locking tooth 333 to limit the rotation of the adjustment gear 33, thereby achieving the locking purpose. When the locking device 4 pops up, the locking device 4 disengages from the second locking tooth 333, thereby achieving the purpose of unlocking.

[0051] like Figures 2 to 12 As shown, the adjusting disk 34 includes a disk body 341 that moves axially along the positioning ring 321, and the inner side wall of the disk body 341 is provided with evenly arranged pit-shaped section grooves 342, and the section grooves 342 cooperate with the section balls 329. When the adjusting disk 34 is rotated, the outer side of the section balls 329 switches between different section grooves 342 of the adjusting disk 34, which not only ensures the accuracy of the position adjustment of the comb set 2, but also gives the user a clear and clear adjustment feedback. The disk body 341 is provided with an arc-shaped female connecting block 343, and the arc-shaped female connecting block 343 is provided on the disk body 341. The block 343 is located in the through hole 324, and the arc-shaped female connecting block 343 matches the wrapped assembly male connecting block 332, so that the adjusting disk 34 drives the adjusting gear 33 to rotate through the arc-shaped female connecting block 343 and the male connecting block 332, and the outer side surface of the arc-shaped female connecting block 343 cooperates with the inner side surface of the positioning ring 321, which not only prevents the adjusting disk 34 from being eccentric, but also plays a radial reinforcement role for the second locking tooth 333 on the adjusting gear 33, thereby avoiding the radial disengagement of the locking device 4 from the second locking tooth 333.

[0052] Embodiment 3: It can be explained on the basis of embodiment 2, such as Figures 2 to 12As shown, the locking device 4 includes a button 41 exposed on the surface of the adjustment device 3. A lock core 42 is fixed in the button 41. A spring 43 is arranged between the button 41 and the bracket 32. The lower end of the spring 43 is located on the center plate 323, and the guide post 325 and the retaining block 326 are located inside the spring 43. An installation groove 44 and a guide groove 45 for the hook 327 to be inserted therein are arranged on the lock core 42. The hook 327 extends into the installation groove 44, which is convenient for assembly. Further explanation, as Figure 11 As shown, the guide groove 45 includes an upper limit portion 451, a lower limit portion 452, an upper reversing portion 453, a lower reversing portion 454, an upward outer guide surface 455, an upward inner guide surface 456, a downward outer guide surface 457, and a downward inner guide surface 458. Such a setting enables the hook of the hook 327 to achieve the unlocking and closing states of the button 41 at different positions in the guide groove 45, which is beneficial to setting the locking device 4 at the central position of the adjustment device 3. The two cooperate with each other to finally achieve the adjustment of the hair cutting length. Even further explanation, a guide hole 421 matching the guide post 325 (axial guide rod) is arranged at the center of the lock core 42. The lock core 42 can move up and down along the guide post 325 (axial guide rod). One side of the lock core 42 located in the guide groove 45 is a plane, which is beneficial to the arrangement of the guide groove 45.

[0053] As Figures 2 to 12 As shown, a circle of third locking teeth 411 is arranged around the button 41. Guide inclined surfaces are arranged below both sides of the third locking teeth 411, and the guide inclined surfaces are in a "V" shape. Such a setting enables the third locking teeth 411 to mesh smoothly with the first locking teeth 322 and the second locking teeth 333 during the locking operation, without jamming or getting stuck with each other.

[0054] The working principle of the present utility model:

[0055] As Figure 13As shown, in the unlocked state, the hook 327 hooks the lower limit portion 452. The lock core 42 and the button 41 bounce up under the spring 43. The third locking tooth 411 of the button 41 disengages from the first locking tooth 322 and the second locking tooth 333. At this time, the adjustment disc 34 can be rotated and the comb sleeve 2 can be adjusted. → When locking is required, press the button 41. The hook of the hook 327 contacts the upward inner guide surface 456 of the guide groove 45 of the lock core 42 and moves upward and rightward relative to the lock core 42. → Keep pressing the button 42. The hook of the hook 327 moves to the highest point on the right under the guidance of the upward outer guide surface 455 of the guide groove 45 of the lock core 42. → In the locked state, release the button 41. The lock core 42 and the button 41 bounce up under the action of the spring 43. The hook of the hook 327 hooks the upper limit portion 451. At this time, the third locking tooth 411 of the button 41 is in an engaged state with the first locking tooth 322 and the second locking tooth 333. The adjustment disc 34 and the adjustment gear 33 are restricted from rotating. → When unlocking is required, press the button 41. The hook of the hook 327 moves to the highest point on the left under the action of the upper commutation portion 453. → Release the button 41. The lock core 42 and the button 41 move upward under the action of the spring 43. The hook of the hook 327 is guided by the downward inner guide surface 458 and the downward outer guide surface 457 of the guide groove 45 of the lock core 42 and finally hooks the lower limit portion 452. The button 41 and the lock core 42 stop moving upward and are at the highest position. The third locking tooth 411 of the button 41 disengages from the first locking tooth 322 and the second locking tooth 333.
