Description

Technical Field

[0001] The utility model belongs to the technical field of hair curlers, in particular to an electric clamping plate structure. Background Art

[0002] An electric hair straightener, also known as an electric hair straightener or an electric hair curler, is used to heat and shape the hair to achieve a straight or curly effect. Currently, in order to achieve both straightening and curling functions, an electric hair straightener is used to achieve both straightening and curling functions.

[0003] To achieve different styling effects on hair, Chinese patent publication CN215271023U discloses a multifunctional hair styling device comprising a base plate, a straightening plate pivotally mounted on one side of the base plate, a straightening assembly for straightening hair disposed between the straightening plate and the base plate, and a curling plate pivotally mounted on the side of the base plate away from the straightening plate, a curling assembly disposed between the curling plate and the base plate. When the straightening plate and the base plate are in contact, the device is in curling mode, and when the curling plate and the base plate are in contact, the device is in straightening mode. A push rod assembly is mounted on the base plate for controlling the base plate to switch between straightening and curling modes. When a user wishes to curl their hair, the curling assembly places their hair between the curling plate and the base plate for curling. When a user wishes to straighten their hair, the user places their hair between the straightening plate and the base plate for straightening. Throughout the entire process, the user can switch between functional modes using the push rod assembly, making the device convenient to use, multi-purpose, and portable, eliminating the need for carrying multiple hair styling devices with different functions. The push rod assembly includes a button plate disposed on a base plate, a first hanging plate fixed to the side of the straightening plate facing the base plate, and a second hanging plate fixed to the side of the curling plate facing the plate plate. A clearance hole is formed through the side of the base plate facing the straightening plate, allowing the first and second hanging plates to extend into the base plate's inner cavity. Both ends of the button plate extend out of the base plate's inner cavity. The button plate is hollow. A first hole is formed on the side of the button plate facing the straightening plate for attaching the first hanging plate, the first hole being connected to the clearance hole. A second hole is formed on the other side of the button plate for attaching the second hanging plate, the second hole being connected to the clearance hole. When the user performs a curling operation, the straightening plate is brought into contact with the base plate, the first hanging plate is attached to the first hole, and the second hanging plate is disengaged from the second hole. The curling plate and the base plate are in an open state, allowing the user to perform a curling operation. Conversely, the user can perform a straightening operation. The mode switching is simple, and the device is also convenient to carry.

[0004] The above-mentioned patent document uses a straightening plate and a curling plate in cooperation with a substrate respectively to realize the functions of curling and straightening hair. And the first hanging plate and the second hanging plate are used in cooperation with the first hole and the second hole of the button plate to realize the switching limit of the straightening plate or the curling plate. However, when both the straightening plate and the curling plate are in a fully unfolded state and the button plate has not slid to the corresponding position, when the straightening plate and the curling plate are clamped on the substrate, the first hanging plate and the second hanging plate cannot be snapped into the corresponding first hole and second hole, but are in contact with the surface of the button plate, resulting in problems such as the button plate being deformed under pressure. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an electric hair straightening and curling iron structure to solve the problems of deformation and the like caused by the self-locking of the hanging plates of the straightening and curling plates in the prior art.

[0006] To achieve the above purpose, an electric hair straightening and curling iron structure provided by an embodiment of the present utility model includes a first clamping plate, a second clamping plate, a third clamping plate and a self-locking structure; the third clamping plate includes a handle shell, and a connecting portion is provided at one end of the handle shell; a first mounting plate extends from one end of the first clamping plate, a second mounting plate is provided at one end of the second clamping plate, and a rotating shaft passes through the connecting portion, the first mounting plate and the second mounting plate; a first limiting groove is provided on the first mounting plate, and a second limiting groove is provided on the second mounting plate; the first limiting groove includes a first guiding groove and a clamping groove, and the clamping groove is provided on one side of the bottom end of the first guiding groove; one end of the second limiting groove overlaps with the lower end of the first guiding groove, and the other end overlaps with the clamping groove;

[0007] The self-locking structure includes a slider, a limiting member and a limiting shaft; the slider is slidably connected in the handle shell, and the limiting member limits the slider; the slider is connected with an operating portion, the operating portion is used to push the slider to slide, the slider extends with a pushing plate, and a second guiding groove is provided on the pushing plate, and the second guiding groove penetrates the top side of the pushing plate; the limiting shaft passes through the first limiting groove, the second limiting groove and the second guiding groove.

[0008] Further, a supporting plate is further provided on the slider, the limiting shaft is pushed into the clamping groove, and the supporting plate supports on the bottom side of the second mounting plate.

[0009] Further, a pressing portion extends upward from one end of the first clamping plate, and a compression spring is further provided between the bottom side of the pressing portion and the handle shell, and the compression spring is used to push the pressing portion upward to clamp the first clamping plate and the second clamping plate or the second clamping plate and the third clamping plate.

[0010] Furthermore, a clearance groove is provided on the bottom side of the handle shell, the operating portion is provided on a toggle block on the bottom side of the slider, and the toggle block passes through the clearance groove.

[0011] Furthermore, the operating portion is rotatably connected to the handle shell, and the operating portion is provided with an eccentric portion abutting against the slider.

[0013] The above one or more technical solutions in the electrical splint structure provided by the embodiment of the present invention have at least the following technical effects:

[0014] To open the first panel freely while the second and third panels are fixed together, the operating unit is pushed, causing the slider to slide. The push plate on the slider pushes the limit shaft to move to the bottom end of the first guide slot. To open the first panel, the first panel rotates about the axis, clearing the limit shaft in the first guide slot, allowing the first mounting plate to swing downward, thereby allowing the first panel to rotate and open. To open the second panel, the operating unit can be used to push the slider backward, causing the push plate on the slider to push the limit shaft, positioning the limit shaft within the slot. To open the second panel, the first panel is also pressed, causing the first mounting plate to rotate about the axis. As the first mounting plate rotates, the top side of the slot pushes the limit shaft downward. The downward rotation of the limit shaft pushes the second mounting plate to rotate together, allowing the second panel to become integrated with the first panel and rotate and open together. This achieves self-locking between the first and second panels, and between the third and second panels. Since the limiting shaft passes through the first limiting slot, the second limiting slot and the second guide slot, and switches between the first limiting slot and the first guide slot, only the first splint and the second splint can be opened freely on one side, or the third splint and the second splint can be opened freely, avoiding the problem of deformation of the self-locking structural parts when the three groups of splints are opened at the same time and then closed.

[0028] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0029] In an embodiment of the electric hair straightener structure of the present utility model, please refer to Figure 1 、 Figure 2 、 Figures 6 to 8, an electric clamping plate structure, used for heating and curling hair. Specifically, it includes a first clamping plate 100, a second clamping plate 200, a third clamping plate 400 and a self-locking structure 430 that can be rotated to open, and the first clamping plate 100, the second clamping plate 200, and the third clamping plate 400 are all provided with electric heating elements (not shown in the drawings). The structure, installation method and heating principle of the electric heating elements are conventional technologies in this field, so they are not described in detail in this embodiment. The first clamping plate 100 is provided with a first clamping surface 101, and the second clamping plate 200 is provided with a second clamping surface 201. The first clamping surface 101 and the second clamping surface 200 are both provided with multiple rows of forming teeth 300, and are staggered, and the mutually staggered forming teeth 300 form a curling clamping position 301. The tooth tips 302 of the forming teeth 300 are externally curved, while the first and second clamping surfaces 101, 201 are provided with internally curved surfaces 102, 202 that mate with the tooth tips 302 of the corresponding forming teeth 300. This electric clamping plate structure allows hair to be pulled out one by one during curling. The first and second clamping plates 100, 200 clamp the pulled-out hair. The forming teeth 300 on the first and second clamping surfaces 101, 201 form a curling clamping area 301 to clamp the hair, creating a wavy, curving effect. The clamping method of the first and second clamping plates 100, 200 makes operation more convenient. Furthermore, users can selectively heat and shape hair at certain locations, such as the ends of the hair, thereby avoiding the need for uniform curling and allowing them to customize their hair. Furthermore, the tooth tops 302 of the curling teeth 300 and the mating surfaces with the first clamping surface 101 or the second clamping surface 201 are respectively located on outer arc and inner arc surfaces, so that the hair can be bent smoothly when clamped, thereby achieving a certain degree of protection for the hair.

[0030] Further, refer to Figure 2 When the first clamping plate 100 and the second clamping plate 200 are clamped together, a gap 303 for clamping hair is formed between the tooth tops 302 and the corresponding inner arc surfaces 102, 202. In this embodiment, when clamping hair, the tooth tops 302 of the forming teeth 300 are prevented from clamping the hair too tightly and causing damage to the hair, thereby providing good protection for the hair.

[0031] For further information, please refer to Figures 1 to 8 The second clamping plate 200 is further provided with a fourth clamping surface 203, and the third clamping plate 400 is provided with a third clamping surface 401. The third clamping plate 400 is provided with an electric heating element. In this embodiment, the third clamping surface 401 and the fourth clamping surface 203 can cooperate to clamp the hair to achieve the effect of straightening or curling the hair, thereby realizing multifunctional curling.

[0032] Further, please refer to Figure 2 , Figure 3 and Figure 5, the third clamping surface 401 and the fourth clamping surface 203 are arc surfaces that are clamped to each other. Among them, the third clamping surface 401 is an inner arc groove surface that is recessed inward, and the fourth clamping surface 203 is an outer arc surface. Using the cooperation of the inner arc surface and the outer arc surface to clamp the hair can not only increase the curling effect, make the hair curl inward more smoothly and have a better effect, but also increase the contact area with the hair, thereby increasing the clamping force on the hair, clamping the hair more tightly, and making the hair receive more uniform heat.

[0033] Further, referring to Figures 2 to 4 , the third clamping plate 400 includes a handle shell 410 and a heat conduction plate 420. An installation cavity 411 is provided inside the handle shell 410, and a control circuit 500 is arranged in the installation cavity 411. One end of the handle shell 410 extends with an installation part 412, an installation groove 413 is provided in the installation part 412, the heat conduction plate 420 is arranged in the installation groove 413, and an electric heating element is arranged inside the heat conduction plate 420. The third clamping surface 401 is arranged on the heat conduction plate 420. A connecting part 413 is provided at one end of the installation part 412 close to the handle shell 410, and the second clamping plate 200 is rotatably connected to the connecting part 413.

[0034] Still further, referring to Figure 2 , an elastic support member 414 is further provided in the installation groove 413, and the heat conduction plate 420 is supported on the elastic support member 414, so that the heat conduction plate 420 can sink toward the bottom side of the installation groove 413. Therefore, by moving the heat conduction plate 420 up and down, the pulling force of the hair can be adjusted to avoid pulling or breaking the hair due to excessive pulling force.

[0035] Further, referring to Figure 4 , Figure 5 , Figure 8 and Figure 9 , a self-locking structure 430 is provided inside the handle shell 410, and the self-locking structure 430 is used to alternately limit the opening of the first clamping plate 100 and the second clamping plate 200. Specifically, when using the forming teeth 300 to curl the hair, the second clamping plate 200 and the third clamping plate 400 can be locked together, and the first clamping plate 100 can be freely opened to realize the function of curling the hair by clamping the hair with the second clamping plate 200. When it is necessary to use the third clamping surface 401 and the fourth clamping surface 203 to clamp the hair for shaping, the first clamping plate 100 and the second clamping plate 200 are locked together through the self-locking structure 430, so that the overall formed by the second clamping plate 200 and the first clamping plate 100 can be freely opened.

[0036] A specific embodiment of the self-locking structure 430 for realizing the self-locking of the first clamping plate 100 and the second clamping plate 200, and the self-locking of the third clamping plate 400 and the first clamping plate 100. Specifically, referring to Figure 4 , Figure 5 , Figure 8 and Figure 9, one end of the first clamping plate 100 extends with a first mounting plate 110, one end of the second clamping plate 200 is provided with a second mounting plate 210, and a rotating shaft 600 passes through the connecting portion 413, the first mounting plate 110 and the second mounting plate 210, so that the first clamping plate 100 and the second clamping plate 200 can rotate freely relative to the third clamping plate 400. More specifically, there are two groups of the first mounting plate 110, the second mounting plate 210, and the connecting portion 413, and they are arranged oppositely, so as to increase the connection stability between the first clamping plate 100 and the second clamping plate 200 and the third clamping plate 400. The first mounting plate 110 is provided with a first limiting groove, and the second mounting plate 210 is provided with a second limiting groove 211. Among them, the first limiting groove includes a first guiding groove 111 and a clamping groove 112, and the clamping groove 112 is provided on one side of the bottom end of the first guiding groove 111. One end of the second limiting groove 211 overlaps with the lower end of the first guiding groove 111, and the other end overlaps with the clamping groove 112; among them,

[0037] Please refer to Figure 5 , Figure 8 and Figure 9The self-locking structure 430 includes a slider 431, a stopper 432, and a stopper shaft 433. The slider 431 is slidably connected within the handle housing 410. The stopper 432 limits the slider 431, allowing it to slide in only one direction. The slider 431 is connected to an operating portion 434. A push plate 435 extends from the slider 431. The push plate 435 is provided with a second guide groove 436 that extends through the top side of the push plate 435. The stopper shaft 433 passes through the first and second stopper grooves 211 and 436. Specifically, when the first splint 100 needs to be opened freely and the second splint 200 and the third splint 400 are fixed as one, the slider 431 is driven to slide by pushing the toggle portion 434 downward, and the push plate 435 on the slider pushes the limit shaft 433 to move to the bottom end of the first guide groove 111. When the first splint 100 is opened, the first splint 100 rotates around the rotating shaft 600, and the limit shaft 433 is avoided by the first guide groove 111, so that the first mounting plate 110 can swing downward, thereby realizing that the first splint 100 can be rotated around the rotating shaft 600 to open. When the second splint 200 is opened, the slider 431 can be pushed backward by the toggle portion 434. The push plate 435 on the slider 431 pushes the limit shaft 433 to move, so that the limit shaft 433 is located in the slot 112. Therefore, when the second splint 200 is opened, the first splint 100 is pressed, causing the first mounting plate 100 to rotate about the rotation axis 600. When the first mounting plate 100 rotates, the top side of the slot 112 pushes the limit shaft 433 to rotate downward. The downward rotation of the limit shaft 433 pushes the second mounting plate 210 to rotate together, so that the second splint 200 and the first splint 100 are integrated and rotated together to open. In this way, the first splint 100 and the second splint 200, and the third splint 400 and the second splint 200 can alternately self-lock and freely open. Since the limiting shaft 433 passes through the first limiting groove, the second limiting groove 211 and the second guide groove 436, and switches between the card slot 112 and the first guide groove 111, only the first splint 100 and the second splint 200 can be opened freely on one side, or the third splint 400 and the second splint 200 can be opened freely, avoiding the problem of deformation of the self-locking structural parts when the three groups of splints are opened at the same time and then closed.

[0038] Further, refer to Figure 8 The slider 431 is further provided with a support plate 437. When the limiting shaft 433 is pushed into the slot 112, the support plate 437 is supported on the bottom side of the second mounting plate 210. This achieves the purpose of limiting the position of the second mounting plate 210. The second clamping plate 200 cannot be rotated open, and only the first clamping plate 100 can be freely opened to clamp and shape the hair curlers.

[0039] Further, refer to Figure 4 , Figure 5 and Figure 8, one end of the first clamping plate 100 further extends upward to form a pressing portion 120. A compression spring 130 is further provided between the bottom side of the pressing portion 120 and the handle housing 400. The compression spring 130 is used to push the pressing portion 120 upward, so that the first clamping plate 100 and the second clamping plate 200 are clamped or the second clamping plate 200 and the third clamping plate 400 are clamped.

[0040] Further, an avoidance groove is provided on the bottom side of the handle housing 410. The operating portion 434 is provided on a toggle block at the bottom side of the slider 431, and the toggle block passes through the avoidance groove. Therefore, the slider 431 can be pushed to slide by the toggle block.

[0041] Further, for another embodiment of the operating portion 434, specifically; the operating portion 434 is rotatably connected to the handle housing 410, and the operating portion 434 is provided with an eccentric portion (not shown in the drawings) that abuts against the slider 431. Therefore, by rotating the operating portion 434, under the action of the eccentric portion, the slider 431 can be pushed to slide.

[0042] Further, referring to Figure 4 , a changeover switch 440 is further provided in the handle housing 410; the heating element and the changeover switch 440 are electrically connected to the control circuit 500. The changeover switch 440 is used to switch the on and off states of the heating elements in each clamping plate. The slider 431 is provided with a pushing member 450, and one end of the pushing member 450 is connected to the changeover switch 440. In this embodiment, when the self-locking structure 430 limits the first clamping plate 100, the pushing member 450 pushes the changeover switch 440, so that the heating element of the first clamping plate 100 and the heating element on the top side of the second clamping plate 200 are powered off, while the heating element in the third clamping plate 400 is powered on, and vice versa. Energy conservation is achieved and a good protection effect is achieved.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
