Description

Technical Field

[0001] This utility model relates to the field of hair straightener technology, and in particular to a hair straightener that is easy to assemble. Background Technology

[0002] A hair straightener, as the name suggests, straightens hair by heating and softening it with a heating element, and then cooling it to achieve the desired straightness.

[0003] In related technologies, hair straighteners include an upper handle assembly, a lower handle assembly, an elastic element, and a shaft. Both the upper and lower handle assemblies have through holes for the shaft to pass through. During installation, the elastic element is first assembled between the upper and lower handle assemblies. Then, the shaft is passed through the through holes in both the upper and lower handle assemblies. Finally, screws are used to connect the upper and lower handle assemblies. However, in this type of hair straightener, the presence of the elastic element makes it easy for the upper and lower handle assemblies to wobble during shaft assembly. This makes it difficult to align the through holes, resulting in difficulty for the shaft to pass through the upper and lower handle assemblies, significantly reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a hair straightener that is easy to assemble, thereby solving the technical problem of low production efficiency caused by the difficulty in assembling hair straighteners in related technologies.

[0005] This application provides a hair straightener that is easy to assemble, which includes an upper handle assembly, a lower handle assembly, an elastic member, and a tail cap. One end of the upper handle assembly is provided with a pivot, and the lower handle assembly has a first receiving groove. The two ends of the elastic member abut against the upper handle assembly and the lower handle assembly, respectively. The tail cap is connected to the lower handle assembly, and a second receiving groove is provided on the side of the tail cap near the lower handle assembly. The upper handle assembly and the tail cap are both located above the lower handle assembly, and the pivot rotates in the left and right directions within the first and second receiving grooves.

[0006] The beneficial effects of this utility model's easy-to-assemble hair straightener are as follows: In this application, the rotating shaft and the upper handle assembly are integrally formed. During installation, the elastic element is assembled between the upper and lower handle assemblies, then the rotating shaft is assembled into the first receiving groove, and finally the tail cap is installed on the lower handle assembly, thus achieving the assembly of the hair straightener. The upper half of the rotating shaft is located in the second receiving groove of the tail cap, and the lower half of the rotating shaft is located in the first receiving groove of the lower handle assembly. When using the hair straightener, the consumer places hair between the upper and lower handle assemblies, presses the upper and lower handle assemblies with their fingers, and the rotating shaft rotates, causing the upper and lower handle assemblies to clamp the hair together. After straightening, the hair straightener is released, and the upper and lower handle assemblies return to their original positions under the action of the elastic element.

[0007] Compared with hair straighteners in related technologies, the hair straightener of this application has an integrally formed shaft and upper handle assembly, and the shaft only needs to pass through the lower handle assembly to achieve the shaft to rotate, which greatly reduces the assembly difficulty of the hair straightener and thus improves production efficiency.

[0008] Furthermore, in related technologies, the use of a shaft core can easily damage the internal leads of the hair straightener, leading to product defects. However, because the shaft and upper handle assembly of this hair straightener are integrally molded, the aforementioned problem does not occur, greatly improving the product yield.

[0009] Optionally, a limit block is provided on the upper surface of the lower handle assembly. The limit block is located above the rotating shaft and is used to limit and abut against the rotating shaft.

[0010] Optionally, a third receiving groove is provided on the lower surface of the limiting block. The third receiving groove penetrates the left and right surfaces of the limiting block and the front surface of the limiting block. The wall of the third receiving groove is used to abut against the rotating shaft. The third receiving groove is provided with a first rounded corner.

[0011] Optionally, the limiting block is located inside the first receiving groove.

[0012] Optionally, the first receiving groove is provided with a second rounded corner.

[0013] Optionally, it also includes a fastener, the tail cap has a through hole, the lower handle assembly has a threaded hole corresponding to the through hole, and the fastener passes through the through hole and is threadedly connected to the threaded hole.

[0014] Optionally, the lower handle assembly is provided with a first protrusion, and the tail cap is provided with a second protrusion for limiting and abutting against the first protrusion.

[0015] Optionally, the first protrusion is located in front of the second protrusion, the surface of the first protrusion facing the second protrusion is a first inclined surface, and the surface of the second protrusion facing the first protrusion is a second inclined surface, wherein the first inclined surface and the second inclined surface are gradually forward from bottom to top.

[0033] Please refer to Figures 1 to 3 The following describes a hair straightener 100 that is easy to assemble according to an embodiment of the present invention.

[0034] Please refer to Figures 1 to 3 This application provides an easy-to-assemble hair straightener 100, comprising an upper handle assembly 10, a lower handle assembly 20, an elastic element 30, and a tail cap 40. The upper handle assembly 10 has a rotating shaft 11 at one end. The lower handle assembly 20 has a first receiving groove 21. The two ends of the elastic element 30 abut against the upper handle assembly 10 and the lower handle assembly 20, respectively. The tail cap 40 is connected to the lower handle assembly 20, and a second receiving groove 41 is provided on the side of the tail cap 40 closest to the lower handle assembly 20. The upper handle assembly 10 and the tail cap 40 are both located above the lower handle assembly 20, with the tail cap 40 located in front of the upper handle assembly 10. The rotating shaft 11 rotates left and right within the first receiving groove 21 and the second receiving groove 41. Specifically, in this embodiment, the elastic element 30 is a spring.

[0035] In this application, the rotating shaft 11 is integrally formed with the upper handle assembly 10. During installation, the elastic element 30 is fitted between the upper handle assembly 10 and the lower handle assembly 20, then the rotating shaft 11 is fitted into the first receiving groove 21, and finally the tail cap 40 is installed on the lower handle assembly 20, thus completing the assembly of the hair straightener. The upper half of the rotating shaft 11 is located in the second receiving groove 41 of the tail cap 40, and the lower half of the rotating shaft 11 is located in the first receiving groove 21 of the lower handle assembly 20. When the consumer uses the hair straightener, they place their hair between the upper handle assembly 10 and the lower handle assembly 20, press the upper handle assembly 10 and the lower handle assembly 20 with their fingers, and the rotating shaft 11 rotates, causing the upper handle assembly 10 and the lower handle assembly 20 to clamp the hair together. After straightening, the hair straightener is released, and the upper handle assembly 10 and the lower handle assembly 20 return to their original position under the action of the elastic element 30.

[0036] Compared with hair straighteners in related technologies, the hair straightener of this application has an integrally formed shaft 11 and upper handle assembly 10, and the shaft 11 only needs to pass through the lower handle assembly 20 to enable the shaft 11 to rotate while facilitating assembly, which greatly reduces the assembly difficulty of the hair straightener and thus improves production efficiency.

[0037] Furthermore, in related technologies, the use of a shaft core can easily damage the internal leads of the hair straightener, leading to product defects. However, since the shaft 11 and the upper handle assembly 10 of this hair straightener are integrally molded, the aforementioned problem does not occur, greatly improving the product yield.

[0038] In another embodiment of this application, please refer to Figures 1 to 3 A limiting block 22 is provided on the upper surface of the lower handle assembly 20. The limiting block 22 is located above the rotating shaft 11 and is used to limit and abut against the rotating shaft 11. Specifically, the limiting block 22 is located above the first receiving groove 21.

[0039] During assembly, after the rotating shaft 11 is installed in the first receiving groove 21, under the restraint of the limiting block 22, the rotating shaft 11 will not move upward even under the action of the elastic element 30. In this way, the operator does not need to press the upper handle assembly 10 continuously, or in other words, does not need to use too much force to press the upper handle assembly 10 to complete the connection between the tail cover 40 and the lower handle assembly 20. If the limiting block 22 is not provided, the operator needs to press the upper handle assembly 10 continuously until the tail cover 40 and the lower handle assembly 20 are connected together.

[0040] The setting of limit block 22 further reduces the assembly difficulty of this hair straightener and helps to improve production efficiency.

[0041] In another embodiment of this application, please refer to Figure 2 and Figure 3The lower surface of the limiting block 22 is provided with a third receiving groove 221, which penetrates the left and right surfaces of the limiting block 22 and the front surface of the limiting block 22. The wall of the third receiving groove 221 is used to limit and abut against the rotating shaft 11. The third receiving groove 221 is provided with a first rounded corner 2211. The first rounded corner 2211 can reduce stress concentration, thereby improving the strength of the limiting block 22 and reducing the risk of the limiting block 22 breaking during the assembly of the hair straightener.

[0042] In another embodiment of this application, please refer to Figure 2 The limiting block 22 is located inside the first receiving groove 21. In this embodiment, the inside of the first receiving groove 21 refers to the side of the first receiving groove 21 closer to the center line of the hair straightener, wherein the center line of the hair straightener is parallel to the front-back direction. The outside of the first receiving groove 21 refers to the side of the first receiving groove 21 away from the center line of the hair straightener. After the upper handle assembly 10 and the lower handle assembly 20 are assembled, the tail cap 40 also needs to be assembled. Compared with setting the limiting block 22 on the outside of the first receiving groove 21, setting the limiting block 22 on the inside of the first receiving groove 21 can reduce the width of the tail cap 40, that is, reduce the length of the tail cap 40 in the left-right direction. In this way, while saving materials and space, a lightweight design is achieved.

[0043] In some embodiments, please refer to Figure 3 The first receiving groove 21 is provided with a second rounded corner 211. The provision of the second rounded corner 211 helps to reduce stress concentration.

[0044] In another embodiment of this application, please refer to Figure 2 The easy-to-assemble hair straightener 100 also includes fasteners (not shown). The tail cap 40 has a through hole 42, and the lower handle assembly 20 has a threaded hole 23 corresponding to the through hole 42. The fastener passes through the through hole 42 and is threadedly connected to the threaded hole 23. Specifically, the through hole 42 extends through both the upper and lower surfaces of the tail cap 40 in a vertical direction, and the threaded hole 23 is located on the upper surface of the lower handle assembly 20 and extends in a vertical direction. The tail cap 40 and the lower handle assembly 20 are detachably connected by screw fastening, which facilitates the recycling or replacement of parts inside the hair straightener.

[0045] It is understood that fasteners can be screws, bolts, etc., and no special limitation is made here.

[0046] In another embodiment of this application, please refer to Figures 1 to 3The lower handle assembly 20 is provided with a first protrusion 24, and the tail cap 40 is provided with a second protrusion 43 for limiting and abutting against the first protrusion 24. Specifically, the first protrusion 24 is connected to the first receiving groove 21, and the second protrusion 43 is connected to the third receiving cavity. During assembly, after the tail cap 40 is placed on the lower handle assembly 20, the second protrusion 43 is located in the first receiving cavity. The provision of the first protrusion 24 and the second protrusion 43 can prevent the tail cap 40 from shifting in the front-to-back direction during the connection with the lower handle assembly 20, and can facilitate the fastener to pass through the through hole 42 and threadedly connect to the threaded hole 23, which helps to improve assembly efficiency.

[0047] In another embodiment of this application, please refer to Figures 1 to 3 The first protrusion 24 is located in front of the second protrusion 43. The surface of the first protrusion 24 facing the second protrusion 43 is a first inclined surface 241, and the surface of the second protrusion 43 facing the first protrusion 24 is a second inclined surface 431. From bottom to top, both the first inclined surface 241 and the second inclined surface 431 gradually move forward. This arrangement facilitates the entry of the second protrusion 43 into the first receiving groove 21, thus improving assembly efficiency.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
