Description

Technical Field

[0001] This invention relates to the field of hair styling device technology, and in particular to a multi-segment variable diameter hair clip. Background Technology

[0002] In related technologies, curling irons are usually of a fixed diameter, with both their outer and inner contours being fixed curves formed by injection molding. These types of hair clips cannot be adjusted in size, and users need to purchase multiple sizes according to different hair volumes or curl patterns, resulting in poor adaptability.

[0003] Later, based on the aforementioned shortcomings, a curling iron with a variable diameter was developed; please refer to [link / reference]. Figure 9 The diagram shows a simplified structure of a variable diameter curling iron. This curling iron has a frame 200, and multiple rotatable styling plates 2001 are arranged around the frame 200. By driving the multiple styling plates 2001 to rotate outward or inward, the diameter can be adjusted to suit different curvature styling needs.

[0004] However, during the actual research and development process, the inventors discovered that when the diameter of the multiple styling plates 2001 is close to the diameter of the skeleton 200, the contact area of ​​the hair wrapped around the outer surface of the multiple styling plates is the largest, and the resulting hair curls are the most natural and continuous. However, when the diameter of the multiple styling plates increases or decreases, after the hair is wrapped around the outer surface of the styling plates with larger or smaller diameters, the hair will only contact the extreme points 2003 between the two styling plates 2001. This results in many gaps 2002 between the two styling plates that cannot be contacted by the hair. Because of the existence of these gaps 2002, the hair will become discontinuous curls after styling, with sections of straight hair and sections of curly hair, resulting in poor styling effect and greatly reducing the user experience.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0006] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a multi-segment variable diameter styling hair clip, effectively solving the technical defect of poor styling effect in the prior art of variable diameter curling irons.

[0007] This invention provides a multi-segment variable diameter hair clip, including... Base body; Adjustable rotating wheel, which is rotatably mounted on the base body; and The adjustable hair clip can be rotated by adjusting a rotating wheel to change its diameter. The base body is fixedly equipped with a fixed hair clip plate, and the movable hair clip plate is cut to form at least a head hair clip plate and a tail hair clip plate; the head hair clip plate is connected to the fixed hair clip plate, and the tail hair clip plate is connected to the head hair clip plate; when the adjusting wheel is rotated, it can drive the head hair clip plate and the tail hair clip plate to move, so that the head hair clip plate and the tail hair clip plate connected in sequence can open outward or close inward to adjust the overall diameter of the hair clip.

[0008] The beneficial effects of the multi-segment variable diameter styling hair clip provided by this invention are as follows: Compared with the prior art, firstly, by cutting the movable hair clip plate into at least a head hair clip plate and a tail hair clip plate, and hinged the head hair clip plate to the fixed hair clip plate, and hinged the tail hair clip plate to the head hair clip plate, a continuous structure with overall linkage is formed; when the adjusting wheel rotates, it can simultaneously drive the head hair clip plate and the tail hair clip plate to move, so that the head hair clip plate and the tail hair clip plate, which are pivotally connected in sequence, open outward or close inward to adjust the overall diameter of the styling hair clip; such a structure can ensure that the outline of the fixed hair clip plate, the head hair clip plate and the tail hair clip plate always maintains a continuous curved shape, rather than discrete point contact, thereby ensuring that there will be no gap between the two plates due to the adjustment of the diameter, and the hair can fit in close to the surface of the hair clip plate throughout the process, fundamentally eliminating the play, ensuring that the curl is continuous, natural and without breaks, and improving the user's styling effect and user experience; Secondly, the movable hair clip plate is hinged to the fixed hair clip plate. At the same time, the first and last hair clip plates of the movable hair clip plate are hinged together in sequence to achieve a hierarchical transmission chain structure. The movable and fixed hair clip plates can be installed without the use of a frame. This structure not only simplifies the overall structure of the styling hair clip, reducing assembly difficulty and manufacturing costs, but also further increases the diameter adjustment range through the structure of the first and last hair clip plates that are hinged in sequence, allowing users to adapt to different curvatures of hair according to different diameter sizes.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Please refer to the following: Figures 1 to 8 The multi-segment variable diameter hair clip 100 provided in this application embodiment will now be described. The multi-segment variable diameter hair clip 100 includes a base body 10, an adjusting wheel 20, and a movable hair clip plate 30.

[0028] The adjusting wheel 20 is rotatably mounted on the base body 10, and the movable hair clip 30 is hinged to the base body 10. The adjusting wheel 20 is used to rotate the movable hair clip 30 to adjust different diameters. The base body 10 is fixedly equipped with a fixed hair clip 40, and the movable hair clip 30 is cut to form at least a head hair clip 31 and a tail hair clip 32. The head hair clip 31 is connected to the fixed hair clip 40, and the tail hair clip 32 is connected to the head hair clip 31. When the adjusting wheel 20 is rotated, it can drive the head hair clip 31 and the tail hair clip 32 to move, so that the head hair clip 31 and the tail hair clip 32 connected in sequence open outward or close inward to adjust the overall diameter of the styling hair clip 100.

[0029] Specifically, compared with the prior art, in the first aspect, by cutting the movable hair clip 30 into at least a head hair clip 31 and a tail hair clip 32, and hinged the head hair clip 31 to the fixed hair clip 40, and hinged the tail hair clip 32 to the head hair clip 31, a continuous structure with overall linkage is formed. When the adjusting wheel 20 rotates, it can simultaneously drive the head hair clip 31 and the tail hair clip 32 to move, so that the head hair clip 31 and the tail hair clip 32 connected in sequence open outward or close inward to adjust the overall diameter of the styling hair clip 100. This structure can ensure that the outline of the fixed hair clip 40, the head hair clip 31 and the tail hair clip 32 always maintains a continuous curved shape, rather than discrete point contact, thereby ensuring that the two pieces of material will not be affected by adjusting the diameter. The gaps created allow the hair to adhere to the surface of the hair clip plate throughout the entire process, fundamentally eliminating any play and ensuring a continuous, natural, and uninterrupted curl, thus improving the user's styling effect and user experience. Secondly, the movable hair clip plate 30 is hinged to the fixed hair clip plate 40, and at least the first and last hair clip plates 31 and 32 of the movable hair clip plate 30 are sequentially hinged together to achieve a hierarchical transmission chain structure. This allows the movable hair clip plate 30 and the fixed hair clip plate 40 to be installed without the need for a frame. This structure not only simplifies the overall structure of the styling hair clip 100, reducing assembly difficulty and manufacturing costs, but also further increases the diameter adjustment range through the sequentially hinged first and last hair clip plates 31 and 32, allowing users to adapt to different hair curvatures according to different diameter sizes.

[0030] More specifically, the end hair clip 32 is provided with a first drive arm 321, the first drive arm 321 having a first connecting shaft 322; the adjusting wheel 20 is provided with an arc-shaped adjusting groove 21, the first connecting shaft 322 being able to be inserted into the arc-shaped adjusting groove 21; by driving the adjusting wheel 20 to rotate, at least the first connecting shaft 322 can be moved from the first adjusting position 211 to the second adjusting position 212 within the arc-shaped adjusting groove 21, so as to sequentially link the head hair clip 31 and the end hair clip 32 to open outward or close inward.

[0031] Preferably, it also includes a third adjustment position 213, which is located between the first adjustment position 211 and the second adjustment position 212; the first adjustment position 211, the second adjustment position 212 and the third adjustment position 213 are all limiting notches, which can maintain the diameter of the movable hair clip 30 in its current state when the first connecting shaft 322 slides into the limiting notch.

[0032] Furthermore, the base body 10 is rotatably mounted with a first adjusting shaft 13, and the center of rotation of the adjusting wheel 20 is provided with a first mounting shaft hole 22 for the first adjusting shaft 13 to be inserted; the first adjusting position 211 of the arc-shaped adjusting groove 21 is set on the side close to the first adjusting shaft 13, and the second adjusting position 212 is set close to the edge of the adjusting wheel 20; when the first connecting shaft 322 slides to the first adjusting position 211, it can sequentially link the head hair clip 31 and the end hair clip 32 to retract inward to the minimum diameter; when the first connecting shaft 322 slides to the second adjusting position 212, it can sequentially link the head hair clip 31 and the end hair clip 32 to open outward to the maximum diameter.

[0033] It should be noted that the arc-shaped adjustment groove 21 can be modified to increase the number of adjustment positions as needed based on actual production requirements or user feedback; for example, between the first adjustment position 211 and the second adjustment position 212, a third adjustment position 213, a fourth adjustment position, a fifth adjustment position, and so on can be added sequentially. In actual use, when the user gradually adjusts the first connecting shaft 322 towards the first position, the diameter can be gradually reduced; when the user gradually adjusts the first connecting shaft 322 towards the second position, the diameter can be gradually increased.

[0034] It is understandable that when the limiting notch structure is removed from each adjustment position, such as the first adjustment position 211, the second adjustment position 212, and the third adjustment position 213, the effect of stepless adjustment of the diameter can be achieved. Different types of adjustment wheels 20 can be selected according to the user's actual needs.

[0035] More specifically, the base body 10 includes a clip base 11 and an adjusting base 12, with a front-to-back distance between the adjusting base 12 and the clip base 11; a fixed hair clip plate 40 extends front-to-back, with one end of the fixed hair clip plate 40 fixed to the rear surface of the adjusting base 12 and the other end fixed to the front surface of the clip base 11, and the fixed hair clip plate 40 is located at the top between the clip base 11 and the adjusting base 12; one end of the first adjusting shaft 13 is rotatably mounted on the clip base 11, and the other end is rotatably mounted on the adjusting base 12. The adjusting wheel 20 has two wheels located at the front and rear ends of the first adjusting shaft 13, and the first drive arm 321 has two wheels located at the front and rear ends of the end hair clip plate 32; the first connecting shaft 322 of one of the first drive arms 321 can be inserted into the arc-shaped adjusting groove 21 of the corresponding adjusting wheel 20.

[0036] For example, one end of the fixed hair clip plate 40 is fastened to the top of the clip base 11 with screws, and the other end is fastened to the top of the adjusting base 12 with screws, so that the front and rear distance between the adjusting base 12 and the clip base 11 is set. At the same time, the adjusting base 12 is rotatably mounted with an adjusting knob 121, and the first adjusting shaft 13 is inserted into the adjusting knob 121. By rotating the adjusting knob 121, the first adjusting shaft 13 is rotated synchronously, which in turn drives the two adjusting wheels 20 to rotate.

[0037] In some embodiments, the fixed hair clip 40 is provided with a fixed end hinge hole 401 on the left and / or right sides, and the head hair clip 31 is provided with a first hinge hole 301 on one side. When the first hinge hole 301 and the fixed end hinge hole 401 are coaxially arranged, the first pin 50 can be inserted into the fixed end hinge hole 401 and the first hinge hole 301, so that the head hair clip 31 can rotate relative to the fixed hair clip 40 around the axis of the first pin 50.

[0038] Specifically, the first hair clip 31 has a second hinge hole 302 on the side opposite to the first hinge hole 301, and the last hair clip 32 has a first hinge hole 301 on the end opposite to the first drive arm 321. When the first hinge hole 301 of the last hair clip 32 and the second hinge hole 302 of the first hair clip 31 are coaxially arranged, the first pin 50 can be inserted into the first hinge hole 301 and the second hinge hole 302, so that the last hair clip 32 can rotate relative to the first hair clip 31 around the axis of the first pin 50.

[0039] For example, the fixed hair clip 40 is provided with fixed end hinge holes 401 on both the left and right sides, and the fixed hair clip 40 is hinged to the left and right sides; when the movable hair clip 30 is only cut with a head hair clip 31 and a tail hair clip 32, the head hair clip 31 is hinged to the left and right sides of the fixed hair clip 40, and the tail hair clip 32 is hinged to the head hair clip 31.

[0040] In other embodiments, the movable hair clip 30 is further divided into a first intermediate hair clip 33 and a second intermediate hair clip 34 with identical structures; one side of the first intermediate hair clip 33 is provided with a first hinge hole 301, and the side opposite to the first hinge hole 301 is provided with a second hinge hole 302; after the first hinge hole 301 of the first intermediate hair clip 33 and the second hinge hole 302 of the head end hair clip 31 are coaxially arranged, they can be inserted into the first hinge hole 301 and the second hinge hole 302 through a first pin 50, so that the first intermediate hair clip 33 can rotate relative to the head end hair clip 31 around the axis of the first pin 50; the second intermediate hair clip 34... After the first hinge hole 301 of the first intermediate hair clip 33 and the second hinge hole 302 of the first intermediate hair clip 33 are coaxially arranged, the first pin 50 can be inserted into the first hinge hole 301 and the second hinge hole 302, so that the second intermediate hair clip 34 can rotate relative to the first intermediate hair clip 33 around the axis of the first pin 50; after the first hinge hole 301 of the end hair clip 32 and the second hinge hole 302 of the second intermediate hair clip 34 are coaxially arranged, the first pin 50 can be inserted into the first hinge hole 301 and the second hinge hole 302, so that the end hair clip can rotate relative to the second intermediate hair clip 34 around the axis of the first pin 50.

[0041] Specifically, by cutting the original rigid, long, curved movable hair clip 30 into a short arc segment structure, the first end hair clip 31, the first middle hair clip 33, the second middle hair clip 34, and the end hair clip 32 can be cut. Furthermore, the first end hair clip 31, the first middle hair clip 33, the second middle hair clip 34, and the end hair clip 32 are sequentially hinged. The outline of this structure, due to the hinged curve, approaches an ideal circular curve. Regardless of the user's adjusted diameter, the gap between the hair and each clip is reduced, ensuring that when the hair is styled on the fixed hair clip 40 and the movable hair clip 30, there will be no discontinuous "straight in one section, curly in another" phenomenon. Its outer contour always maintains a continuous curved shape, rather than discrete point contact; regardless of the diameter change, the hair can adhere to the hair clip surface throughout, fundamentally eliminating any gaps and ensuring a continuous, natural, and discontinuous curl.

[0042] Furthermore, it also includes multiple first torsion springs 51, each of which is sleeved in a first pin 50. The first torsion springs 51 provide elastic force to the head hair clip 31, the first intermediate hair clip 33, the second intermediate hair clip 34, and the end hair clip 32.

[0043] More specifically, the first torsion spring 51 includes a spring body 511, a first elastic arm 512, and a second elastic arm 513. The spring body 511 is sleeved in the first pin 50. The first torsion spring 51 located between the first-end hair clip 31 and the fixed hair clip 40 has its first elastic arm 512 abutting against the inner side of the first-end hair clip 31, and its second elastic arm 513 abutting against the inner side of the fixed hair clip 40. The first torsion spring 51 located between the first-end hair clip 31 and the first intermediate hair clip 33 has its first elastic arm 512 abutting against the inner side of the first intermediate hair clip 33. The second elastic arm 513 abuts against the inner side of the first hair clip plate 31; the first torsion spring 51 located between the first intermediate hair clip plate 33 and the second intermediate hair clip plate 34 has one first elastic arm 512 abutting against the inner side of the second intermediate hair clip plate 34 and the second elastic arm 513 abutting against the inner side of the first intermediate hair clip plate 33; the first torsion spring 51 located between the second intermediate hair clip plate 34 and the end hair clip plate 32 has one first elastic arm 512 abutting against the inner side of the end hair clip plate 32 and the second elastic arm 513 abutting against the inner side of the second intermediate hair clip plate 34.

[0044] Specifically, by setting a first torsion spring 51 between the first hair clip plate 31, the first intermediate hair clip plate 33, the second intermediate hair clip plate 34, and the end hair clip plate 32, a lateral preload can be provided, ensuring that there is no play during the closing or retraction of each movable hair clip plate 30, and ensuring that the styling hair clip 100 can change precisely when its diameter changes. At the same time, the first torsion spring 51, as a flexible medium, absorbs the instantaneous impact force and the reaction force of the hair during the adjustment process, allowing each movable hair clip plate 30 to self-adapt to each other, avoiding hard pulling on the root of the cutting seam of the board, and significantly extending the service life of the movable styling board.

[0045] It is understandable that the first hair clip 31, the first intermediate hair clip 33, the second intermediate hair clip 34 and the end hair clip 32 can be connected in sequence by means of hinge, pivot, elastic connection and additional support, as long as the first hair clip 31, the first intermediate hair clip 33, the second intermediate hair clip 34 and the end hair clip 32 can be rotated in sequence.

[0046] It should be noted that the outer surfaces of the first hair clip 31, the first intermediate hair clip 33, the second intermediate hair clip 34, and the end hair clip 32 are all curved surfaces.

[0047] More specifically, a hair clip plate 111 is pivotally connected to the top of the clip base 11. The hair clip plate 111 has an upper clip 112, and the clip base 11 has a lower clip 113. A second torsion spring 114 is provided between the upper clip 112 and the lower clip 113. The second torsion spring 114 can provide an elastic force to the hair clip plate 111, so that when no force is applied to the upper clip 112 and the lower clip 113, the hair clip plate 111 can abut against the upper surface of the fixed hair clip plate 40. When hair styling is required, the upper clip 112 and the lower clip 113 are applied, so that the hair clip plate 111 moves upward and retracts relative to the fixed hair clip plate 40. After the hair is wrapped around the fixed hair clip plate 40 and the movable hair clip plate 30, the application of the upper clip 112 and the lower clip 113 can be canceled, and the hair clip plate 111 and the fixed hair clip plate 40 are used to hold the hair for hair styling.

[0048] In some embodiments, a hair treatment device is also provided, which is a hair dryer 200 or a heater; when the hair treatment device is a hair dryer 200, the styling hair clip 100 can be inserted into the air outlet of the hair dryer 200, and hot air is provided by the hair dryer 200 to blow onto the fixed hair clip plate 40 and the movable hair clip plate 30 to heat the fixed hair clip plate 40 and the movable hair clip plate 30, so as to heat and style the hair with the fixed hair clip plate 40 and the movable hair clip plate 30; when the hair treatment device is a heater, the styling hair clip 100 can be heated by the heater, and the heated fixed hair clip plate 40 and the movable hair clip plate 30 can be used to heat and style the hair.

[0049] The above are merely preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way.
