Description

Technical Field

[0001] The invention relates to an accessory of a hair cutter, in particular to a limiting comb. Background Art

[0002] The existing hair cutters, whether for shop use or home use, are all used to cut hair to a certain length through the limit comb on the hair clippers. At present, the hair cutters generally on the market are equipped with different types of limit combs to meet the needs of different people. People change a certain limit comb according to how short they want to cut hair. If they need to cut hair into a certain shape, they need to frequently replace the limit comb, which is not only very troublesome to disassemble and assemble the limit comb, but also makes the limit comb easy to break. Summary of the invention

[0003] Based on the above problems, the present invention proposes a dial limit comb with a self-locking function. The position of the limit comb on the comb frame is adjusted by the dial to adjust the cut length of the hair cutter. At the same time, it has a self-locking function to achieve hair cutting accuracy.

[0004] The technical scheme adopted is: a dial limit comb with a self-locking function, including a limit comb, a comb frame, a scale rod and a dial; the limit comb and the limit frame cooperate, and the dial is fixed on the comb frame; the scale rod is installed on the comb frame, passes through the comb frame and cooperates with the limit comb;

[0005] The limiting comb comprises a head seat and a base, which are connected to form an integral body; positioning grooves are provided on both sides of the head seat; a through hole is provided on the base, and a rack is provided on one side of the through hole; a convex strip is provided on one side of the base, and a sawtooth is provided on the convex strip; and a guide groove is also provided on the outer side of the base;

[0006] The comb frame has a circular hole at the bottom, positioning holes are formed around the outer side of the circular hole, and a comb frame concave platform is formed inside; a guide rail is fixed to the inner wall of the comb frame, and the guide rail cooperates with the guide groove on the limit comb to install the limit comb on the comb frame, and the limit comb can move up and down through the guide rail; a through hole is formed on one side of the circular hole; a limit groove, a boss buckle and a comb frame boss are formed on the outer wall of the bottom of the comb frame; the limit groove is semicircular with the circular hole as the center, a boss buckle is fixed on one side of the limit groove, and a comb frame boss is fixed on one side of the circular hole;

[0007] The dial is matched with the limit comb through the round hole on the comb frame; a gear is arranged in the middle of the dial, a positioning circle is fixed on the outer periphery of the gear, and a limit buckle is arranged on the positioning circle; the gear is meshed with the rack on the limit comb, the positioning circle is matched with the positioning hole outside the round hole on the comb frame, and the limit buckle is matched with the comb frame concave platform to fix the dial on the bottom of the comb frame; a scale groove is arranged on the inner wall of the dial, a positioning boss is arranged at one end of the scale groove, and the positioning boss is matched with the limit groove on the comb frame; a scale plate is arranged on the outer side of the dial;

[0008] The scale rod comprises a first support rod and a second support rod; the first support rod and the second support rod are connected by a round shaft; the round shaft is hollow and is installed on the boss buckle of the comb frame; one end of the first support rod is provided with a reverse tooth; the first support rod passes through the through hole on the comb frame, and the reverse tooth engages with the sawtooth on the limit comb; one end of the second support rod is provided with a boss, and the other side of the boss is provided with a spring column; the boss is clamped on the positioning slot on the dial; a spring is installed on the spring column, and one end of the spring is installed on the boss of the comb frame.

[0009] Furthermore, the guide rails on the combing frame include long guide rails and short guide rails.

[0010] Furthermore, a positioning rib is fixed on the comb frame, and the positioning rib cooperates with a positioning groove on the limit comb; when the limit comb is in a low position, the comb frame and the limit comb are aligned on both sides.

[0011] Furthermore, the boss is triangular in shape.

[0012] The invention has a simple structure and few parts. The position of the limit comb on the comb frame can be adjusted at any time by driving the gear on the dial to achieve the required hair trimming length. The boss is always stuck on the scale groove of the dial through the spring tension, and the inverted teeth on the first lever are always engaged with the saw teeth on the limit comb. When the dial is in a certain working gear, the reverse force applied to the limit comb during operation, when the dial is not turned, the inverted teeth and the saw teeth will be tightly engaged, so that the boss on the scale rod is always in contact with the scale groove of the dial, forming an automatic locking state, so as to realize the self-locking function of the limit comb.

[0013] When the dial is turned, the boss and the scale groove, the inverted teeth and the saw teeth will move first due to the tension of the spring, and the inverted teeth on the first lever and the saw teeth will be disengaged first, so as to ensure the hand feeling and comfort when turning the dial. When the dial is turned, the gear on the dial rotates, and the guide rail on the comb frame slides on the guide groove on the limit comb, so as to realize the displacement of the limit comb. The present invention has few parts, simple structure, stable trimming length, and solves the problems of precision, hand feeling and self-locking of the limit comb and the locking device of the hairdressing tool.
