[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figure 1-4As shown, an assembled heating rod for a hair curler includes a heating rod body 1, a support frame 6 inside the heating rod body 1, a cover 7 threadedly connected to the right side of the heating rod body 1, the left side of the cover 7 abutting against the right side of four sets of heating plates 4, a guide strip 2 provided on the inner side wall of the heating rod body 1, and a sliding groove 201 provided on the left side and bottom of the guide strip 2, and four sets of guide strips 2 are arranged in a circular array on the inner wall of the heating rod body 1.

[0015] In this solution, by setting a support frame 6 inside the heating rod body 1, a stable support effect is achieved for the internal structure of the heating rod, ensuring that the heating rod is not easily deformed or damaged during long-term use, thus extending the overall service life. Secondly, four sets of circular array guide bars 2 are set. Through the sliding grooves 201 opened on the left side and bottom of the guide bars 2, a precise guiding effect is achieved for the heating plate 4 during the installation process, enabling the heating plate 4 to be quickly and accurately positioned to the designated position, thus improving assembly efficiency.

[0016] Reference Figure 1-3 As shown, a locking mechanism 3 is provided on the inner side of the guide bar 2, and a heating plate 4 is movably installed on the inner side of the guide bar 2. A cover plate 5 is provided directly above the heating plate 4. There are four sets of cover plates 5. A spring plate 501 is provided on the left side of the four sets of cover plates 5. An unlocking block 502 is fixedly installed at the bottom of the four sets of spring plates 501. The four sets of unlocking blocks 502 are located directly above the locking plate 304. There are four sets of heating plates 4. Slide bars 401 are provided at the four corners of the front and rear sides of the four sets of heating plates 4. A locking block 402 is provided on the left side of the four sets of heating plates 4. The four sets of locking blocks 402 are locked inside the locking plate 304.

[0017] In this solution, a snap-fit ​​mechanism 3 is set inside the guide strip 2 to achieve a reliable fixing effect on the heating plate 4, preventing the heating plate 4 from loosening or shifting during operation and ensuring the stability of heating performance. The mounting plate 301 in the snap-fit ​​mechanism 3 has a fixing plate 302 fixedly installed at its top. By opening two sets of mounting grooves 303 on the fixing plate 302, the two sets of snap-fit ​​plates 304 can be flexibly rotated and installed, improving the adaptability of the snap-fit.

[0018] Reference Figure 1-4 As shown, the snap-fit ​​mechanism 3 includes a mounting plate 301. The snap-fit ​​mechanism 3 is provided in four sets, and the four sets of snap-fit ​​mechanisms 3 are arranged in a circular array inside the guide strip 2. A fixing plate 302 is fixedly installed on the top of the mounting plate 301. An installation groove 303 is opened through the right side on the left outer surface of the fixing plate 302. There are two sets of installation grooves 303. A snap-fit ​​plate 304 is rotatably installed inside the two sets of installation grooves 303. A spring 305 is provided on the inner side of the left end of the two sets of snap-fit ​​plates 304.

[0019] In this design, springs 305 are installed on the inner left side of the two sets of clamping plates 304, achieving an elastic clamping effect between the clamping plates 304 and the heating plate 4. When the heating plate 4 is installed in place, the springs 305 provide appropriate pressure to firmly clamp the heating plate 4. At the same time, when disassembly is required, the unlocking block 502 is fixedly installed at the bottom of the spring plate 501, achieving a convenient unlocking effect for the clamping plates 304. When the heating plate 4 needs to be disassembled, simply press the unlocking block 502 to open the clamping plates 304, thereby smoothly removing the heating plate 4. The operation is simple and convenient, facilitating the replacement and maintenance of the heating plate 4. Secondly, four sets of heating plates 4 are provided. By setting slide bars 401 at the four corners of the front and rear sides of the heating plate 4, a sliding cooperation effect with the slide groove 201 on the guide bar 2 is achieved, further enhancing the stability and smoothness of the installation of the heating plate 4.

[0020] The working principle of this utility model is as follows: First, the support frame 6 provides stable support for the overall structure inside the heating rod body 1, preventing deformation and damage from long-term use. The four sets of annular array guide bars 2, with their left side and bottom sliding grooves 201, provide precise guidance for the installation of the heating plate 4, enabling the heating plate 4 to be quickly positioned. During installation, the sliding strips 401 at the four corners of the front and rear sides of the heating plate 4 slide and engage with the sliding grooves 201 on the guide bars 2, improving installation stability and smoothness. The snap-fit ​​mechanism 3 on the inner side of the guide bars 2 fixes the heating plate 4. Two sets of mounting grooves 30 are opened on the fixing plate 302 at the top of the mounting plate 301. 3. This allows the two sets of clamping plates 304 to rotate flexibly during installation. When the heating plate 4 is installed in place, the clamping block 402 on its left side enters the interior of the clamping plate 304. The spring 305 on the inner side of the left end of the clamping plate 304 provides pressure, which makes the clamping plate 304 firmly clamp the heating plate 4, preventing it from loosening or shifting during operation and ensuring stable heating performance. When it is necessary to remove the heating plate 4, press the unlocking block 502 at the bottom of the spring plate 501 on the left side of the cover plate 5. The unlocking block 502 acts on the clamping plate 304, causing the clamping plate 304 to open. The clamping block 402 on the left side of the heating plate 4 disengages from the clamping plate 304, so that the heating plate 4 can be easily removed for easy replacement and maintenance.
