Description
Technical Field
[0001] The utility model relates to the technical field of hair styling devices, and in particular to a locking mechanism for a hair styling device. Background Art
[0002] In today's society, the pursuit of beauty has become a trend among people. Beautiful hair can better showcase one's individual beauty, and hair styling tools are indispensable. Hair styling tools generally include straighteners and curlers.
[0003] With the continuous update of users' usage requirements, hair styling tools that can be used for both straightening and curling have emerged on the market. A hair styling tool that can be used for both straightening and curling usually includes two handles. A heating plate is provided on each handle, and the handle is provided with a blowing port and a blower. When straightening hair, the heating plate is heated, two pieces are opened to put in the hair and then closed, and then the heating plate can be pulled along the extension direction of the hair to straighten the hair. When the two handles are closed and the hair is wound around the outside of the two handles, the hair can be blown and curled by using the blower.
[0004] In order to improve the convenience of use when the hair styling tool is switched to straightening or curling, a locking mechanism is required to limit the opening and closing of the two handles. When curling is needed, the opening and closing of the two handles are locked by the locking mechanism. When straightening operation is needed, the opening and closing of the two handles are unlocked by the locking mechanism. The locking mechanism usually includes a push button and a lock core. By pushing the push button into the locking position or the unlocking position, the push button can be inserted into or withdrawn from the lock core to control the opening and closing state of the two handles.
[0005] However, the inventor found in the actual research and development process that for this type of locking mechanism, once the two handles are opened, it is very easy for the user to accidentally operate the push button into the locking position. At this time, when the user closes the two handles, the push button will interfere because it has entered the locking position in advance, causing the push button to impact the outer surface of the lock core and unable to cooperate with the lock core to lock the two handles. During this impact process, the push button is easily damaged, indicating that it is not reliable in use.
[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model
[0007] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide a locking mechanism for a hair styling device, which effectively solves the technical defect that the locking mechanism for a hair styling device in the existing technology is unreliable in use.
[0008] To achieve the above purpose, the present utility model adopts the following technical solution: A locking mechanism for a hair styling device includes a hair styling device and a locking mechanism provided on the hair styling device. The hair styling device is provided with a first handle and a second handle that are pivotally connected to each other and can be opened or closed. The locking mechanism locks the first handle and the second handle.
[0009] The locking mechanism includes a locking member, a lock core and a stop protrusion. The locking member can move along a first path to enter the locked position or the unlocked position. When the first handle and the second handle are closed, the locking member can enter the locked position and connect with the lock core to lock the first handle and the second handle. When the first handle and the second handle are opened, the stop protrusion can limit the locking member from entering the locked position.
[0010] The beneficial effect of the locking mechanism of the hair styling device provided by this application is as follows: When it is necessary to lock the first handle and the second handle, rotate the first handle and the second handle relative to each other to complete the closing, and then push the locking member into the locked position and connect it with the lock core, then the locking of the first handle and the second handle can be achieved. Once the locking member is disconnected from the lock core, after the first handle and the second handle are opened relative to each other, the stop protrusion can be used to limit the locking member from entering the locked position, so as to ensure that the user will not accidentally operate the locking member to enter the locked position after the first handle and the second handle are opened. Compared with the prior art, when the first handle and the second handle are in the open state, it effectively avoids the situation that the locking member enters the locked position in advance, resulting in impact and damage to the locking member during the subsequent closing process of the first handle and the second handle, further improving the reliability of the locking mechanism during use and extending the service life of the locking mechanism.
[0011] As a preferred solution: The locking member is movably installed on the first handle, and the lock core is fixedly installed on the second handle. The locking member and the lock core are arranged front and back. When the locking member moves back and forth along the first path, it can be connected to the lock core for locking or disconnected for unlocking.
[0012] As a preferred solution: The hair styling device further includes a base, and the first handle and the second handle are pivotally connected to the base. When the locking member is movably installed on the first handle and / or the second handle, the lock core is fixedly installed on the base. When the locking member is movably installed on the base, the lock core is fixedly installed on the first handle and / or the second handle.
[0013] As a preferred solution: When the lock core is provided on the first handle, the stop protrusion is provided on the first handle. When the lock core is provided on the second handle, the stop protrusion is provided on the second handle.
[0014] When the lock core is provided on the base, the stop protrusion is provided on the base.
[0015] As a preferred solution: A first locking protrusion is provided on the rear side of the locking member, and a first locking groove is provided on the front side of the lock core. When the first handle and the second handle are rotated relative to each other and closed, the first locking protrusion can be inserted into the first locking groove.
[0016] As a preferred solution: The first handle is a hollow shell structure with a first installation cavity. A first travel groove is provided at the top of the first handle, and the first travel groove penetrates downward through the first installation cavity; The locking member is movably installed in the first installation cavity. A first push rod is provided at the top of the locking member, and the first push rod extends upward through the first travel groove. The top of the first push rod protrudes from the top of the first handle.
[0017] As a preferred solution: The front end and the rear end of the first travel groove extend along a first path. The front end of the first travel groove is the unlocking position, and the rear end of the first travel groove is the locking position; When the first push rod is pushed forward into the unlocking position, the first locking convex portion can withdraw from the first locking groove; When the first push rod is pushed backward into the locking position, the first locking convex portion can be inserted into the first locking groove.
[0018] As a preferred solution: The locking mechanism further includes
[0019] a limiting frame, which is fixedly installed on the first handle; The limiting frame is provided with a first limiting groove, and the locking member is movably installed in the first limiting groove.

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0034] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.
[0037] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application will be described first.
[0039] In the prior art, a hair styling device that can be used for both straightening and curling includes an upper handle and a lower handle, and the upper handle and the lower handle are provided with a heating plate and an air outlet. When performing a straightening operation, the upper handle and the lower handle are opened, the hair is placed between the two clamping plates, and then the upper handle and the handle are closed and pulled along the extension direction of the hair to straighten the hair. When performing a curling operation, the upper handle and the lower handle are closed, and the hair is wound around the outer surfaces of the upper handle and the lower handle, and by blowing air out through the air outlet, the hair can be blown into curls.
[0040] When curling is needed, the opening and closing of the upper handle and the lower handle are locked by a locking mechanism; the locking mechanism generally includes a push button and a lock core. By pushing the push button into the locked position or the unlocked position, the push button can be inserted into or withdrawn from the lock core to control the opening and closing state of the upper handle and the lower handle. For this type of locking mechanism, once the two handles are opened, it is very easy for the user to accidentally operate the push button into the locked position. At this time, when the user closes the two handles, the push button will interfere because it has entered the locked position in advance, causing the push button to impact the outer surface of the lock core and unable to cooperate with the lock core to lock the two handles. During this impact process, the push button is easily damaged.
[0041] Please refer to Figures 1 to 6 , and now the locking mechanism 20 of the hair styling device 10 provided by the embodiments of the present application will be described. The locking mechanism 20 of the hair styling device 10 includes: the hair styling device 10 and the locking mechanism 20.
[0042] The hair styling device 10 includes a first handle 11 and a second handle 12. The first handle 11 and the second handle 12 are pivotally connected to each other so that the first handle 11 and the second handle 12 can be opened or closed to clamp hair for straightening. A locking mechanism is installed in the hair styling device. The locking mechanism is used to lock the first handle 11 and the second handle 12. The locking mechanism 20 includes a locking member 21, a lock core 22 and a stop protrusion 23. The locking member 21 can move along a first path x1 to enter a locking position 1112 or an unlocking position 1111. When the first handle 11 and the second handle 12 are closed, the locking member 21 can enter the locking position 1112 and connect with the lock core 22 to lock the first handle 11 and the second handle 12. When the first handle 11 and the second handle 12 are opened, the stop protrusion 23 can limit the locking member 21 from entering the locking position 1112.
[0043] When it is necessary to lock the first handle 11 and the second handle 12, rotate the first handle 11 and the second handle 12 relative to each other to complete the closing, and then push the locking member 21 into the locking position 1112 and connect it with the lock core 22, then the locking of the first handle 11 and the second handle 12 can be realized. Once the locking member 21 is disconnected from the lock core 22, after the first handle 11 and the second handle 12 are opened relative to each other, the stop protrusion 23 can be used to limit the locking member 21 from entering the locking position 1112.
[0044] It can be seen that through the arranged stop protrusion 23, after the first handle 11 and the second handle 12 are opened, the locking member 21 can be prevented from entering the locking position 1112, thereby preventing the locking member 21 from entering the locking position 1112 in advance when the first handle 11 and the second handle 12 are in the open state, resulting in impact and damage to the locking member 21 during the subsequent closing process of the first handle 11 and the second handle 12, further improving the reliability of the locking mechanism 20 during use and being able to extend the service life of the locking mechanism 20.
[0045] In some embodiments of the present application, the locking member 21 is movably installed on the first handle 11, and the lock core 22 is fixedly installed on the second handle 12. The locking member 21 and the lock core 22 are arranged front and back. When the locking member 21 moves back and forth along the first path x1, it can be connected to the lock core 22 for locking or disconnected for unlocking.
[0046] It should be noted here that the locking member 21 can also be arranged on the second handle 12. When the locking member 21 is arranged on the second handle 12, the lock core 22 is correspondingly arranged on the first handle 11. As long as the first handle 11 and the second handle 12 can be locked by the connection between the locking member 21 and the lock core 22 after being closed.
[0047] Specifically, a first locking convex portion 211 is provided at the rear side of the locking member 21, and a first locking groove 221 is provided at the front side of the lock core 22; when the first handle 11 and the second handle 12 are relatively rotated and closed, the first locking convex portion 211 can be inserted into the first locking groove 221.
[0048] It can be understood that since the locking member 21 and the lock core 22 are arranged front and back, the first locking convex portion 211 is correspondingly provided at the rear side of the locking member 21, and the first locking groove 221 is correspondingly provided at the front side of the lock core 22, so that the first locking convex portion 211 can cooperate with the first locking groove 221 to complete the locking or unlocking operation. When the lock core 22 and the locking member 21 are arranged front and back, the first locking groove 221 is provided at the rear side of the lock core 22, and the first locking convex portion 211 is provided at the front side of the locking member 21.
[0049] More specifically, the first handle 11 is a hollow housing structure having a first installation cavity 112. A first travel groove 111 is provided at the top of the first handle 11, and the first travel groove 111 penetrates downward through the first installation cavity 112; the locking member 21 is movably installed in the first installation cavity 112. A first push rod 212 is provided at the top of the locking member 21, and the first push rod 212 extends upward through the first travel groove 111, and the top of the first push rod 212 protrudes from the top of the first handle 11.
[0050] The front end and the rear end of the first travel groove 111 extend along a first path x1. That is to say, the first travel groove 111 extends back and forth along the first path x1; the front end of the first travel groove 111 is the unlocking position 1111, and the rear end of the first travel groove 111 is the locking position 1112; when the first push rod 212 is pushed forward into the unlocking position 1111, the first locking convex portion 211 can withdraw from the first locking groove 221; when the first push rod 212 is pushed backward into the locking position 1112, the first locking convex portion 211 can be inserted into the first locking groove 221.
[0051] It should be noted here that the unlocking position 1111 and the locking position 1112 need to be used in cooperation with the first locking convex portion 211 and the first locking groove 221. For example, when the first push rod 212 is pushed backward to insert the first locking convex portion 211 into the first locking groove 221, the unlocking position 1111 and the locking position 1112 need to be arranged front and back to allow the first push rod 212 to be pushed forward into the unlocking position 1111 to disengage the first locking convex portion 211 from the first locking groove 221.
[0052] In addition, the forward and backward movement of the locking member 21 and the first push rod 212 mentioned in this application are only for clearly explaining the specific working principle of the locking mechanism 20. If the locking member 21 and the first push rod 212 are changed to move left and right, that is, the first path x1 extends in the left-right direction; and the first locking groove 221 is adaptively provided on the left and right sides of the lock core 22, the first locking protrusion 211 can also move left and right and insert into the first locking groove 221.
[0053] In some other embodiments of this application, the locking mechanism 20 further includes a limiting frame 24; the limiting frame 24 is fixedly installed on the first handle 11. After the limiting frame 24 is fixedly installed on the first handle 11, the bottom of the limiting frame 24 is flush with the bottom of the first handle 11; the limiting frame 24 is provided with a first limiting groove 241, and the locking member 21 is movably installed in the first limiting groove 241.
[0054] The limiting frame 24 is provided with a gear plate 242, and the upper surface of the gear plate 242 has a gear protrusion 243; the lower surface of the locking member 21 is provided with a gear groove 213 for the gear protrusion 243 to be adaptively inserted. Specifically, there is one gear protrusion 243 and two gear grooves 213, and the two gear grooves 213 are spaced along the extension direction of the first path x1. The two gear grooves 213 are adapted to be used with the unlocking position 1111 and the locking position 1112. When the gear protrusion 243 is inserted into the front gear groove 213, the first push rod 212 enters the locking position 1112; when the gear protrusion 243 is inserted into the rear gear groove 213, the first push rod 212 enters the unlocking position 1111.
[0055] With such a structure, by providing the gear plate 242 and the gear protrusion 243, when the user operates the first push rod 212 to enter the unlocking position 1111 or the locking position 1112, a damped gear can be obtained; at the same time, it is also convenient for the position of the first push rod 212 not to change easily after entering the unlocking position 1111 or the locking position 1112, improving the reliability of use.
[0056] Specifically, the limiting frame 24 is provided with a first through hole 244, and the first through hole 244 is exposed on the lower surface of the first handle 11; the lock core 22 is installed on the upper surface of the second handle 12. When the first handle 11 and the second handle 12 are relatively rotated and closed, the lock core 22 is inserted into the first through hole 244.
[0057] In some embodiments of this application, the stop protrusion is integrally formed on the lock core, and a first arc-shaped guiding surface is provided on the side surface of the stop protrusion facing the locking member.
[0058] Specifically, when the locking member 21 is movably mounted on the first handle and the lock core is mounted on the second handle, the stop protrusion 23 is integrally formed on the top of the lock core 22. The first arc-shaped guiding surface is provided on the front surface of the stop protrusion and extends backward from bottom to top. The first arc-shaped guiding surface 231 is smoothly transitioned with the front surface of the lock core 22. After the first push rod 212 is pushed forward to move into the unlocking position 1111, the rear side surface of the first locking protrusion 211 is always located in front of the lock core 22 and the stop protrusion 23. During the opening process of the first handle 11 and the second handle 12, the first locking protrusion 211 can be switched from the front side of the lock core 22 to the front side of the first arc-shaped guiding surface 231. However, when the first push rod 212 is pushed backward at this time, the rear side of the first locking protrusion 211 abuts against the first arc-shaped guiding surface 231 to limit the first push rod 212 from entering the locking position 1112.
[0059] Specifically, the opening stroke of the first handle 11 and the second handle 12 is defined as the second path a1, and the stop protrusion 23 is located within the numerical range of the second path a1. For example, when the maximum angle at which the first handle 11 and the second handle 12 open along the second path a1 is 45 degrees, at least a part of the stop protrusion 23 coincides with the position of 45 degrees, and at least a part of the stop protrusion 23 has an area for the first locking protrusion 211 to abut against, so as to limit the first push rod 212 from entering the locking position 1112.
[0060] In some other embodiments of the present application, the hair styling device 10 further includes a base, and the first handle 11 and the second handle 12 are pivotally connected to the base. When the locking member 21 is movably mounted on the first handle 11 and / or the second handle 12, the lock core 22 is fixedly mounted on the base. When the locking member 21 is movably mounted on the base, the lock core 22 is fixedly mounted on the first handle 11 and / or the second handle 12. When the lock core 22 is provided on the first handle 11, the stop protrusion 23 is provided on the first handle 11. When the lock core 22 is provided on the second handle 12, the stop protrusion 23 is provided on the second handle 12. When the lock core 22 is provided on the base, the stop protrusion 23 is provided on the base.
[0061] It can be understood that when the lock core 22 is provided on the base, locking members can be provided on both the first handle and the second handle. At this time, the lock core is provided with a stop protrusion corresponding to the locking members of the first handle and the second handle. With such a structure, after the first handle and the second handle are closed, the locking members of the first handle and the second handle can be locked with the lock core. When the first handle and the second handle are opened, the two stop protrusions can respectively stop the locking members of the first handle and the second handle from entering the locking position.
[0062] Specifically, by flexibly setting the positions of the lock element 21, the lock core 22 and the stop protrusion 23, the first handle 11 and the second handle 12 can be locked; when the first handle 11 and the second handle 12 are opened, as long as the position where the stop protrusion 23 is set can stop the lock element 21 from entering the locked position; the lock element 21, the lock core 22 and the stop protrusion 23 are mentioned in this application only to specifically describe the working principle of the locking mechanism 20, and their specific positions are not limited to this.
[0063] It should be noted here that the hairdressing device can be a hair straightener with only a hair straightening function, or a hair straightening and curling dual-purpose hair straightening and curling function; as long as these hairdressing devices have two handles that are opened or closed to each other, a locking mechanism can be provided to lock the two handles.
[0064] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
