Description

Technical Field

[0001] The utility model relates to a comb, in particular to a comb with retractable comb teeth. Background Art

[0002] When combing hair with a comb, if the hair is long, it is easy to get tangled in the comb teeth, which is troublesome to clean. Therefore, combs with retractable comb teeth have appeared on the market. However, in the prior art, the retractable structure is easily worn, resulting in a short service life of the comb. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the utility model provides a comb with retractable comb teeth.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a comb with retractable comb teeth, including a shell, a comb tooth assembly, and a plurality of connecting rods. The shell is provided with a main rod that can slide in the shell, the comb tooth assembly includes a base plate and comb teeth arranged on the base plate, and the shell is provided with a through hole for the comb teeth to pass through. One end of the connecting rod is hinged to the main rod, and the other end is hinged to the base plate. When the main rod slides in the shell, it drives the connecting rod to move, and then drives the comb tooth assembly to move, thereby realizing the switching of the extended state and the retracted state of the comb teeth.

[0005] The shell body is provided with a first sliding groove, and the corresponding main rod is detachably connected with a first sliding block which can slide in the first sliding groove, and the first sliding block is provided with a button.

[0006] The main rod is provided with at least one second sliding groove, and the corresponding housing is provided with a corresponding number of second sliding blocks that can slide in the second sliding groove.

[0007] The main rod is provided with a first clamping portion and a second clamping portion, and the corresponding shell is provided with a first clamping block. When the comb teeth are in an extended state, the first clamping block is clamped with the first clamping portion, and when the comb teeth are in a retracted state, the first clamping block is clamped with the second clamping portion.

[0008] A plurality of third sliding grooves are arranged on the side of the bottom plate, and guide ribs corresponding to the third sliding grooves are arranged in the shell.

[0009] The shell comprises an upper shell, a lower shell and a head cover. The upper shell and the lower shell are detachably connected. After the upper shell and the lower shell are connected, the head cover is sleeved on one end of the upper shell and the lower shell.

[0010] The utility model has the beneficial effects that the utility model adopts the telescopic structure of the connecting rod, which is not easy to wear, easy to use and has a long service life. The utility model also realizes the firm positioning of the comb teeth in the extended state and the retracted state by setting the first clamping part, the second clamping part and the first clamping block.

[0018] like Figure 1-Figure 7 As shown, a comb with retractable comb teeth 202 includes a housing 1, a comb tooth 202 assembly 2, and a plurality of connecting rods 3. The housing 1 is provided with a main rod 4 that can slide in the housing 1. The comb tooth 202 assembly 2 includes a bottom plate 201 and comb teeth 202 arranged on the bottom plate 201. The housing 1 is provided with a through hole 101 for the comb teeth 202 to pass through. One end of the connecting rod 3 is hinged to the main rod 4, and the other end is hinged to the bottom plate 201. When the main rod 4 slides in the housing 1, it drives the connecting rod 3 to move, and then drives the comb tooth 202 assembly 2 to move, so as to switch the extended state and retracted state of the comb teeth 202. In this embodiment, four connecting rods 3 are provided in the housing 1. The connecting rods 3 are symmetrically arranged in pairs, and the corresponding main rods 4 are provided with first rotating shafts that are symmetrical in pairs. The bottom plate 201 is provided with first connecting holes that are symmetrical in pairs. The lower end of the connecting rod 3 is provided with a second connecting hole that is sleeved on the first rotating shaft, and the upper end of the connecting rod 3 is provided with a second rotating shaft that is sleeved on the first connecting hole. Connecting rods 3 of different numbers or structures may also be provided according to the size of the comb or other requirements.

[0019] The housing 1 is provided with a first slide groove 102, and the corresponding main rod 4 is detachably connected with a first slider 5 that can slide in the first slide groove 102, and the first slider 5 is provided with a button 6. The button 6 can more conveniently slide the main rod 4. In this embodiment, the first slider 5 is connected to the main rod 4 by a buckle, and can also be connected by other forms such as screws and threads.

[0020] The main rod 4 is provided with at least one second sliding groove 401 , and the housing 1 is correspondingly provided with a corresponding number of second sliding blocks 103 that can slide in the second sliding groove 401 .

[0021] The main rod 4 is provided with a first clamping portion 402 and a second clamping portion 403, and the corresponding housing 1 is provided with a first clamping block 104. When the comb teeth 202 are in an extended state, the first clamping block 104 is clamped with the first clamping portion 402, and when the comb teeth 202 are in a retracted state, the first clamping block 104 is clamped with the second clamping portion 403. The first clamping portion 402, the second clamping portion 403, and the first clamping block 104 are provided to achieve a secure clamping position of the comb teeth 202 in the extended state and the retracted state. In this embodiment, the first clamping block 104 is semi-cylindrical, and this shape can play a transition role when the first clamping block 104 is inserted and pushed out, which is convenient for use. One or more third clamping portions can also be provided between the first clamping portion 402 and the second clamping portion 403 to achieve multi-stage adjustment of the extended length of the comb teeth 202.

[0022] A plurality of third sliding grooves 203 are disposed on the side of the bottom plate 201 , and guide ribs 105 corresponding to the third sliding grooves 203 are disposed in the housing 1 .

[0023] The housing 1 includes an upper shell 11, a lower shell 12, and a head cover 13. The upper shell 11 and the lower shell 12 are detachably connected. After the upper shell 11 and the lower shell 12 are connected, the head cover 13 is sleeved on one end of the upper shell 11 and the lower shell 12.

[0024] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
