[0030] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.

[0031] The following will be described in detail with reference to the drawings Figures 1-7 The present application will be further described in detail.

[0032] The present application provides a comb with telescopic function, which refers to Figure 1 The comb with telescopic function comprises a shell 1, a comb needle assembly 2 movably installed in the shell 1, a first telescopic driving assembly 3 and a second telescopic driving assembly 4. The first telescopic driving assembly 3 and the second telescopic driving assembly 4 are located on the same side of the comb needle assembly 2 and are arranged at intervals, and the first telescopic driving assembly 3 and the second telescopic driving assembly 4 move synchronously towards or away from each other along the length direction of the comb needle assembly 2 and are movably connected with the comb needle assembly 2. When the comb is not used, the first telescopic driving assembly 3 and the second telescopic driving assembly 4 are synchronously moved relative to the shell 1 to drive the comb needle assembly 2 to retract and hide in the shell 1, and when the comb is used, the first telescopic driving assembly 3 and the second telescopic driving assembly 4 are synchronously moved in reverse to drive the comb needle assembly 2 to extend out of the shell 1. During the telescopic process of the comb needle assembly 2, the moving distance of the first telescopic driving assembly 3 and the second telescopic driving assembly 4 can be shortened, the time is reduced, and the efficiency during the telescopic process of the comb needle assembly 2 is improved.

[0033] Refer to Figure 1 With Figure 2 The shell 1 comprises a mounting portion and a holding handle portion, the mounting portion is connected to one end of the holding handle portion, the holding handle portion is held by the user's hand, and the comb needle assembly 2, the first telescopic driving assembly 3 and the second telescopic driving assembly 4 are all mounted on the mounting portion. The width of the holding handle portion is smaller than the width of the mounting portion, on the one hand, it is convenient for the user to hold the holding handle portion with the hand, and on the other hand, it makes the mounting portion have a larger space for mounting the comb needle assembly 2, the first telescopic driving assembly 3 and the second telescopic driving assembly 4.

[0034] Further, the shell 1 comprises a first shell 11, a second shell 12, and a tail cover 13, and the first shell 11 and the second shell 12 are respectively provided with a half of the mounting portion and the handle portion. The side of the first shell 11 and the second shell 12 close to each other is provided with an assembly chamber, that is, the side of the first shell 11 and the second shell 12 close to each other is open. The first shell 11 and the second shell 12 are connected by clamping, so that the assembly is convenient and the cost is low. In another embodiment, the first shell 11 and the second shell 12 can be connected by screws. The tail cover 13 is clamped and mounted on the end of the handle portion away from the rotating portion to shield the opening of the end of the handle portion away from the mounting portion. The end of the first shell 11 and the second shell 12 is inserted into the tail cover 13. The tail cover 13 can improve the fault tolerance rate when the first shell 11 and the second shell 12 are assembled, and also improve the stability of the first shell 11 and the second shell 12 after being connected.

[0035] Referring to Figure 2 With Figure 3 , the comb assembly 2 can reciprocate inside the shell 1 along the direction from the second shell 12 to the first shell 11, and the comb assembly 2 can extend or retract through the mounting portion of the first shell 11. The outer wall of the side of the mounting portion of the first shell 11 away from the second shell 12 is provided with an arc surface 111, which is bent along the extension direction of the first shell 11, that is, the middle position of the mounting portion of the first shell 11 is bent towards the second shell 12, so that the shell 1 can fit the user's scalp better during combing, improving the comfort during combing.

[0036] The edge of the side of the first shell 11 close to the second shell 12 is integrally formed with a connecting buckle plate 112, which extends towards the second shell 12 and is in a cantilevered state. The cavity wall of the assembly chamber of the second shell 12 is integrally formed with a side wall clamping protrusion 121, which can be clamped into the connecting buckle plate 112, so that the first shell 11 and the second shell 12 are clamped and connected together. Among them, the connecting buckle plate 112 is provided with multiple, and the multiple connecting buckle plates 112 are arranged circumferentially on the mounting portion of the first shell 11. Correspondingly, the number of side wall clamping protrusions 121 is consistent with the number of connecting buckle plates 112 and one-to-one correspondence, so that the mounting portion of the first shell 11 and the second shell 12 is more stable after being connected. In another embodiment, the connecting buckle plate 112 can be provided on the second shell 12, and the side wall clamping protrusion 121 is provided on the first shell 11.

[0037] The inner part of the holding handle part of the second shell 12 is integrally formed with a connecting buckle plate, and the inner part of the holding handle part of the first shell 11 is integrally formed with a clamping plate clamped on the connecting buckle plate, thereby improving the stability of the first shell 11 and the second shell 12 after being connected.

[0038] Referring to Figure 1 With Figure 2 , one end of the tail cover 13 is integrally formed with an annular flange 131 and a plug-in sleeve 132, the plug-in sleeve 132 is located inside the annular flange 131, and the outer diameter of the plug-in sleeve 132 is smaller than the inner diameter of the annular flange 131. The plug-in sleeve 132 is inserted into the end of the holding handle part of the first shell 11 and the second shell 12 away from the mounting part, and the end of the holding handle part of the first shell 11 and the second shell 12 away from the mounting part is inserted between the annular flange 131 and the plug-in sleeve 132, thereby limiting the first shell 11 and the second shell 12 along the direction of being clamped and buckled, and making the first shell 11 and the second shell 12 more stable after being spliced together. The inner wall of the holding handle part of the first shell 11 and the second shell 12 is integrally formed with a handle clamping protrusion, and the outer wall of the plug-in sleeve 132 is provided with a connecting clamping groove for clamping the handle clamping protrusion of the first shell 11 and the second shell 12, thereby enabling the tail cover 13 to be clamped and connected with the first shell 11 and the second shell 12, and improving the stability after being connected. The tail cover 13 is connected with the first shell 11 and the second shell 12 through the clamping structure, which makes the assembly more convenient and reduces the production cost. In another embodiment, the tail cover 13 can be connected with the first shell 11 and the second shell 12 by screws.

[0039] Referring to Figure 2 With Figure 3 , the comb needle assembly 2 includes an integrated plate 21 and a plurality of comb teeth needles 22, the plurality of comb teeth needles 22 are integrally formed on the same side of the integrated plate 21 and are arranged at intervals, and the comb teeth needles 22 are used for combing hair. The first shell 11 is provided with a plurality of comb needle holes 113 on one side of the arc surface 111 for the comb teeth needles 22 to pass through, and the number of the comb needle holes 113 is the same as and corresponds to the number of the comb teeth needles 22. The movement of the first telescopic driving assembly 3 and the second telescopic driving assembly 4 will drive the integrated plate 21 to move, and the integrated plate 21 will drive the comb teeth needles 22 to extend out of or retract into the comb needle holes 113 after moving.

[0040] Since multiple comb pins 22 need to extend from one side of the first housing 11 where the arc surface 111 is provided, the integrated plate 21 is directly set as an arc-shaped plate equidistant from the arc surface 111 to ensure that the shape of the extended length of the multiple comb pins 22 is also an arc shape that matches the shape of the arc surface 111. This setting also allows multiple comb pins 22 to extend or retract together from the corresponding comb pin holes 113, so that when the comb pins 22 retract, the hair wrapped around different comb pins 22 can be smoothly removed, making it less likely for the hair to wrap around other comb pins 22 after it is removed. In another embodiment, the integrated plate 21 can be a straight plate, while the multiple comb pins 22 have different lengths forming an arc shape.

[0041] Reference Figure 2 and Figure 3 The assembly chamber of the second housing 12 has four sets of directional plates 122 integrally formed. Each set of directional plates 122 consists of two spaced-apart stiffeners, with the gap between the two stiffeners being a directional groove 123. Four directional posts 23 are integrally formed on the side walls of the integrated plate 21 on opposite sides. The four directional posts 23 are located at the four corners of the integrated plate 21, and each of the four directional posts 23 corresponds to one of the four directional grooves 123. The directional posts 23 move directionally within the directional grooves 123, thereby enabling the integrated plate 21 to move directionally during movement.

[0042] Reference Figure 3 and Figure 4 The first telescopic drive assembly 3 includes a first substrate 31 and a first side plate 32. The first substrate 31 is located on the side of the integrated plate 21 away from the comb needles 22. Two first side plates 32 are provided, each integrally formed on the side of the first substrate 31 near the integrated plate 21 and arranged symmetrically at intervals. The integrated plate 21 is located between the two first side plates 32. First mating posts 24 are integrally formed on the side walls of opposite sides of the integrated plate 21. The first side plate 32 has a first driving groove 321 for the first mating post 24 to be inserted and slid. The first driving groove 321 is gradually inclined towards the first substrate 31 along the direction of approaching the second telescopic drive assembly 4. Thus, as the first side plate 32 slides towards or away from the second telescopic drive assembly 4, the first mating post 24 moves from one end to the other end of the first driving groove 321. At the same time, in conjunction with the cooperation of the directional post 23 and the directional groove 123, the comb needles 22 are driven to extend or retract. To facilitate the insertion of the first mating post 24 into the first driving inclined groove 321, a groove is provided on the inner wall of the first side plate 32 at one end of the first driving inclined groove 321.

[0043] Reference Figure 3 and Figure 4, similarly, the second telescopic driving assembly 4 comprises a second base plate 41 and two second side plates 42. The second base plate 41 is located on the side of the integrated plate 21 away from the comb teeth 22, and the two second side plates 42 are integrally formed on the side of the second base plate 41 close to the integrated plate 21 and are symmetrically and spacedly arranged. The integrated plate 21 is located between the two second side plates 42, and the second matching column 25 is integrally formed on the side wall of the integrated plate 21. The second side plate 42 is provided with a second driving inclined groove 421 for inserting and sliding the second matching column 25. The second driving inclined groove 421 is gradually inclined towards the second base plate 41 in the direction close to the first telescopic driving assembly 3. Thus, in the process of sliding the second side plate 42 towards or away from the first telescopic driving assembly 3, the second matching column 25 moves from one end to the other end of the second driving inclined groove 421, and at the same time, the directional column 23 and the directional groove 123 are combined to drive the comb teeth 22 to extend or retract. In order to facilitate the insertion of the second matching column 25 into the second driving inclined groove 421, a groove is formed in the inner wall of the second side plate 42 at one end of the second driving inclined groove 421.

[0044] Wherein, the first base plate 31 is integrally formed with a driving rack 33 on the side close to the second base plate 41, and a rotating column is integrally formed on the cavity wall of the assembly chamber of the second shell 12. A transmission gear 14 is sleeved and rotatably installed on the rotating column, and the transmission gear 14 is meshed with the driving rack 33. A screw is installed on the rotating column to limit the axial movement of the transmission gear 14, so that the transmission gear 14 is not easy to fall off the second shell 12. The second base plate 41 is integrally formed with a driven rack 43 at one end close to the first base plate 31, and the driven rack 43 is meshed with the transmission gear 14. When the first base plate 31 and the first side plate 32 move, the driving rack 33 moves synchronously to drive the transmission gear 14 to rotate; the transmission gear 14 rotates to drive the driven rack 43 to move; and then the second base plate 41 and the second side plate 42 are driven to move towards or away from the first telescopic driving assembly 3 synchronously.

[0045] Referring to Figure 3 With Figure 4Further, the driving rack 33 is a bidirectional rack (i.e., the opposite sides have protruding teeth), the transmission gear 14 is provided with two, and the two transmission gears 14 are respectively located on the two sides of the driving rack 33 and are in meshing with the driving rack 33, and the driving rack 33 moves to drive the two transmission gears 14 to rotate synchronously. The driven rack 43 is symmetrically and spacedly provided with two, and the two transmission gears 14 are located between the two driven racks 43 and are in meshing with the two driven racks 43 one by one. Compared with the single-side stress of the second substrate 41, the above-mentioned arrangement makes the second substrate 41 be able to receive uniform force on the opposite sides, and the phenomenon of jamming or locking due to uneven stress during movement is not easy to occur. In another embodiment, the driving rack 33 can be arranged on the first side plate 32, and the driven rack 43 can be arranged on the second side plate 42.

[0046] In combination Figure 1 With reference to Figure 3 With Figure 4 The second shell 12 is provided with a push key 15 on the side away from the first shell 11, and a moving groove 124 is formed on the side of the second shell 12 away from the first shell 11, the moving groove 124 is in communication with the assembly chamber on the second shell 12, the push key 15 is inserted into the moving groove 124 and can slide in the moving groove 124, and one end of the push key 15 protrudes from the second shell 12 for the user to push. The push key 15 can be fixedly connected with the first telescopic driving assembly 3; or can be fixedly connected with the second telescopic driving assembly 4, so that the user only needs to drive the push key 15 to move to drive the first telescopic driving assembly 3 and the second telescopic driving assembly to move to drive the integrated plate 21 to move to drive the comb teeth 22 to extend or retract. The push key 15 is preferably fixedly connected to the first substrate 31 in the first telescopic driving assembly 3 by a screw in the embodiment. In another embodiment, the push key 15 can not be provided, but a part of the first substrate 31 or the second substrate 41 is directly pushed through the moving groove 124.

[0047] In combination Figure 4 With reference to Figure 5 With Figure 6The push key 15 is integrally formed with a shielding plate 151 at one end close to the second base plate 41. When the push key 15 is moved, the shielding plate 151 can shield the moving slot 124, so that dust is not easy to enter the inside of the assembly chamber through the moving slot 124. The first and second gear protrusions 125 and 126 are integrally formed on the cavity wall of the second housing 12 at intervals. The first gear protrusion 125 is located between the first base plate 31 and the second base plate 41, and the second gear protrusion 126 is located on the side of the first base plate 31 away from the second base plate 41. The side wall of the shielding plate 151 is provided with a gear clamping groove 5 for clamping the first gear protrusion 125. When the gear clamping groove 5 on the shielding plate 151 clamps the first gear protrusion 125, the comb teeth 22 are in the extended state. The end of the first base plate 31 away from the second base plate 41 is also provided with a gear clamping groove 5. When the second gear protrusion 126 clamps the gear clamping groove 5 on the first base plate 31, the comb teeth 22 are in the retracted state. Such arrangement makes the comb teeth 22 in the extended state or the retracted state be clamped and limited more stably.

[0048] In combination Figure 5 With reference to Figure 6 With Figure 7 In some embodiments, the gear clamping groove 5 can also be provided on the second base plate 41 to clamp the first gear protrusion 125; or two gear clamping grooves 5 are directly provided on the first base plate 31 to clamp the first and second gear protrusions 125 and 126 respectively; or a gear clamping groove 5 is provided on the push key 15 to clamp the second gear protrusion 126; or the first and second gear protrusions 125 and 126 are respectively provided on the two sides of the sliding direction of the second base plate 41, and then two gear clamping grooves 5 are provided on the second base plate 41 to clamp the first and second gear protrusions 125 and 126 respectively.

[0049] In another embodiment, the first and second telescopic driving assemblies 3 and 4 can each be only one sliding block with an inclined surface. The inclined surfaces of the two sliding blocks abut against the integrated plate 21, and the two sliding blocks are connected by a linkage to realize synchronous movement towards or away from each other. When the two sliding blocks move close to each other, the integrated plate 21 moves under the action of the inclined surface to make the comb teeth 22 extend; similarly, when the two sliding blocks move away from each other, the integrated plate 21 moves under the action of the inclined surface to make the comb teeth 22 retract.

[0050] The implementation principle of the comb with the telescopic function is that when the comb needle assembly 2 is driven to extend out of the shell 1, the push key 15 is directly driven to move away from the holding handle part, in this process, the first side plate 32 and the driving rack 33 are both moved to the middle part of the integrated plate 21; the driving rack 33 drives the transmission gear 14 to rotate, the transmission gear 14 drives the driven rack 43 to move and drives the second side plate 42 to move, thereby making the first side plate 32 and the second side plate 42 close to each other, at the same time, the first matching column 24 and the second matching column 25 on the integrated plate 21 are respectively moved to the direction close to the first shell 11 under the action of the first driving inclined groove 321 and the second driving inclined groove 421 and make the comb tooth needle 22 extend out of the comb tooth hole 113. In addition, at this time, the first gear position protrusion 125 is clamped into the gear position clamping groove 5 on the shielding plate 151 to limit the extension and retraction of the comb tooth needle 22.

[0051] When the comb needle assembly 2 is driven to retract into the shell 1, the push key 15 is reversely moved, the driving rack 33 drives the transmission gear 14 to reversely rotate, the transmission gear 14 drives the driven rack 43 to move and drives the second side plate 42 to move, thereby making the first side plate 32 and the second side plate 42 move away from each other, at the same time, the first matching column 24 and the second matching column 25 on the integrated plate 21 are respectively moved to the direction away from the first shell 11 under the action of the first driving inclined groove 321 and the second driving inclined groove 421 and make the comb tooth needle 22 completely retract into the comb tooth hole 113 and the assembly chamber.
