Description

Technical Field

[0001] The present invention relates to the field of hair clippers, and particularly to a limit comb adjusting mechanism and a hair clipper. Background Art

[0002] The limit comb accessory has a comb-shaped member that covers the blade portion of the electric hair clipper, and forms a fixed-length interval between the blade portion and the human skin. The trimming height can be changed as the installation position of the fixed-length limit comb accessory changes. In the past, there have been electric hair clippers configured to use a limit comb to control the trimming height, and different trimming lengths are achieved by replacing multiple limit combs with different limit heights.

[0003] Most current limit combs are pushed horizontally when pushed, without a sense of gear operation. Summary of the Invention

[0005] The technical solution adopted by the present invention is as follows:

[0006] The limit comb adjusting mechanism includes a housing, a limit comb slidably fitted on the housing, a first limit portion and a gear portion floatingly arranged on the housing, and a pressing portion and a second limit portion arranged on the limit comb; the first limit portion includes a first position in limit cooperation with the second limit portion and a second position away from the second limit portion; the pressing portion is provided with a plurality of gear grooves with arc-shaped surfaces, and the gear portion is provided with gear blocks that slidably cooperate with the gear grooves when the limit comb slides.

[0007] A floating plate is arranged inside the housing, and the first limit portion and the gear portion are arranged outside the housing with a part of the floating plate protruding out of the housing.

[0008] It further includes an elastic member for driving the floating plate to make the first limit portion extend out of the housing.

[0009] The pressing portion is a pressing plate arranged on the limit comb, and the pressing plate is used to contact the floating plate when pressed.

[0010] A rotating shaft is arranged on the floating plate, the gear portion is arranged at the middle end of the floating plate, the rotating shaft is arranged on one side of the gear portion, and the first limit portion is arranged on the other side of the gear portion.

[0011] The gear groove is a wavy groove.

[0012] A sliding groove is arranged on the housing, and a sliding block slidably cooperating with the sliding groove is arranged on the inner wall of the limit comb.

[0013] The first limiting part is a boss provided on the floating plate. The boss includes a first blocking surface and a first sliding surface that is inclined. The second limiting part is a convex block provided on the limiting comb. The convex block includes a second sliding surface that slidably cooperates with the first sliding surface and a second blocking surface that blockingly cooperates with the first blocking surface.

[0014] The housing is provided with a first through groove for a part of the first limiting part to pass through and a second through groove for a part of the gear part to pass through. When the floating plate is pressed, the first limiting part is not higher than the surface of the housing.

[0026] The present invention will be further described below in conjunction with the accompanying drawings: As shown in the figure, the limit comb adjusting mechanism includes a housing 1, a limit comb 2 is slidably fitted on the housing, a first limit portion 3 and a gear portion 4 are floatingly arranged on the housing, and a pressing portion 5 and a second limit portion 6 are arranged on the limit comb; the first limit portion includes a first position that is in limit fit with the second limit portion and a second position that is away from the second limit portion; the pressing portion is provided with a plurality of gear grooves 51 with an arc-shaped surface, and a gear block 41 that slidably cooperates with the gear grooves when the limit comb slides is arranged on the gear portion. The first limit portion provides positioning when the limit comb slides in place, and the gear portion provides cooperation with it when the pressing portion is pressed, so as to obtain a stepped operating feeling when sliding. This floating can be realized by an elastic member such as a spring, or can also be realized by using rubber, etc. The first limit portion can be a boss, and the second limit portion can be a groove adapted to it.

[0027] In this embodiment, as shown in the figure, a floating plate 7 is arranged inside the housing, and the first limit portion and the gear portion are arranged on a part of the floating plate that extends out of the housing. The floating of a floating plate is used to realize two structures, which is compact in structure and better in use effect.

[0028] In this embodiment, as shown in the figure, an elastic member 8 is further included, and the elastic member is used to drive the floating plate to make the first limit portion extend out of the housing. The elastic member is a spring, a spring piece, etc.

[0029] In this embodiment, as shown in the figure, the pressing portion is a pressing plate arranged on the limit comb, and the pressing plate is used to contact the floating plate when pressed. One end of the pressing plate can be connected to the limit comb, and the other end extends out and relies on its own elasticity to reset.

[0030] In this embodiment, as shown in the figure, a rotating shaft 70 is arranged on the floating plate, the gear portion is arranged at the middle end of the floating plate, the rotating shaft is arranged on one side of the gear portion, and the first limit portion is arranged on the other side of the gear portion. A shaft hole matched with the rotating shaft can be arranged inside the housing, and the distance between the axis of the first limit portion and the axis of the rotating shaft is greater than the distance between the axis of the gear portion and the axis of the rotating shaft. In this way, when the rotating shaft rotates, the rotating distance of the first limit portion is larger, and the first limit portion can be preferentially extended into the housing, and the pressing portion can always be in contact with the gear portion.

[0031] In this embodiment, as shown in the figure, the gear groove is a wavy groove. It is more stable when sliding and better in use effect.

[0032] In this embodiment, as shown in the figure, a sliding groove is arranged on the housing, and a sliding block 54 that slidably cooperates with the sliding groove is arranged on the inner wall of the limit comb. The sliding is realized through the sliding groove and the sliding block, which has a simple structure and is convenient to use.

[0033] In this embodiment, as shown in the figure, the first limiting portion is a boss provided on the floating plate. The boss includes a first blocking surface 31 and a first sliding surface 32 that is inclined. The second limiting portion is a convex block provided on the limiting comb. The convex block includes a second sliding surface 61 that slidably cooperates with the first sliding surface and a second blocking surface 62 that blockingly cooperates with the first blocking surface. When in use, press the pressing plate, and the floating plate descends. The first limiting portion can entirely enter the housing or partially protrude outside the housing. When it protrudes outside the housing, the first sliding surface can be arranged like a slope. When sliding forward, the second sliding surface contacts the first sliding surface to reduce resistance. After reaching the position, release the finger, and the floating plate resets. The first blocking surface and the second blocking surface cooperate to prevent it from retracting. Multiple such convex blocks can be provided, and a limiting groove 621 for the limiting cooperation of a single boss is formed between two adjacent convex blocks.

[0034] In this embodiment, as shown in the figure, the housing is provided with a first through groove 12 for a part of the first limiting portion to pass through and a second through groove 13 for a part of the gear portion to pass through. When the floating plate is pressed, the first limiting portion is not higher than the surface of the housing.

[0035] In this embodiment, as shown in the figure, the elastic member is a spring.

[0036] In this embodiment, as shown in the figure, the hair clipper includes the limiting comb adjusting mechanism as described above.
