[0014] like Figures 1 to 5 As shown, an automatic cord retractor for an electric heating table includes a cord retractor base 10, a rotating cord reel 20, and a cord retractor cover 30. The cord retractor base 10 has a recessed cord reel mounting groove 11, in which the rotating cord reel 20 is installed. The cord retractor cover 30 covers the cord retractor base 10. The front of the cord retractor base 10 has a cord inlet opening 12. In use, the power cord of the power plug can pass through the cord inlet opening 12 and be wound and stored on the rotating cord reel 20, thus achieving orderly storage of the power cord.

[0015] In practical implementation, the coil mounting groove 11 has a coil connecting post 13 in the middle, and the rotating take-up coil 20 has a coil connecting groove 21 in the middle. The diameter of the coil connecting groove 21 is larger than the diameter of the coil connecting post 13. The coil connecting post 13 is connected in the coil connecting groove 21, so that the rotating take-up coil 20 can be rotatably installed in the coil box base 10. The rotating take-up coil 20 has a winding ring 22 in the middle, and the winding ring 22 has a wire outlet opening 221 on its side. In use, one end of the power cord is led out through the wire outlet opening 221, and the remaining part is wound around the winding ring 22 for storage, thereby realizing the orderly arrangement and convenient storage of the power cord.

[0016] In practical implementation, a circular cable exit slot 31 is provided in the middle of the cable box cover 30. The cable exit slot 31 is located at the upper end of the cable winding ring 22. A fixed cable code 23 is installed inside the cable winding ring 22. A rotating cable code 32 is installed on one end surface of the cable box cover 30. A rotating coil 321 is provided in the middle of the rotating cable code 32. During use, the power cord passes through the fixed cable code 23 and the rotating coil 321 in sequence. The fixed cable code 23 is used to limit and fix a part of the power cord to prevent it from sliding or tangling abnormally during the rotation and winding process. The rotating coil 321 can adapt to the angle of movement of the power cord during the pulling out or retraction process, reduce the risk of cable twisting or tangling, and further improve the smoothness and service life of the power cord winding and unwinding. This structure is simple and eliminates the complex design of multiple gear components such as three gears working together in the traditional anti-tangling structure, reducing the structural complexity and manufacturing cost, while significantly improving the smoothness and service life of the power cord winding and unwinding. By preventing the power cord from twisting and knotting during use, damage to the wire core is effectively avoided, thereby further improving the lifespan of the power cord and its safety during use.

[0017] In practical implementation, the inside of the winding ring 22 is provided with a first wire code mounting seat 24, and the fixed wire code 23 is set on the first wire code mounting seat 24 and is connected and fixed to the first wire code mounting seat 24 by fasteners passing through the fixed wire code 23. One end surface of the wire box cover 30 is provided with a second wire code mounting seat 33, and the rotating wire code 32 is set on the second wire code mounting seat 33 and is connected and fixed to the second wire code mounting seat 33 by fasteners passing through the rotating wire code 32. The structure design is simple, easy to process and assemble, and the installation method is stable and firm, which can effectively prevent the wire code from loosening, shifting or falling off during long-term use.

[0018] In practical implementation, symmetrical roller connecting posts 14 are provided on both sides of the inlet opening 12. Inlet rollers 15 can be rotatably fitted onto the outer sides of both roller connecting posts 14. During use, when the power cord is led out, its path passes through the gap between the two inlet rollers 15 and contacts the outer surface of the inlet rollers 15. The inlet rollers 15 can rotate freely with the direction of power cord pulling, thereby reducing wear caused by friction during power cord insertion or pulling. This structure not only effectively reduces wear and damage to the power cord sheath but also avoids jamming caused by direct friction between the power cord and the fixed structure, improving the smoothness and durability of the overall cord retraction system. It can further enhance the reliability and service life of the automatic cord retraction box for electric heating tables under frequent use conditions.

[0019] In practical implementation, a disc spring 16 is provided on the inner side of the coil mounting groove 11, and a spring retaining groove 131 is provided on the side of the coil connecting post 13. A spring retaining edge 161 is provided on the inner side of the disc spring 16, and the spring retaining edge 161 is engaged in the spring retaining groove 131. During use, as the rotating take-up reel 20 rotates, the disc spring 16 is synchronously driven to undergo torsional deformation and gradually accumulate elastic potential energy. When the user releases the power cord or triggers the retraction operation, the disc spring 16 quickly releases its stored elastic potential energy, driving the rotating take-up reel 20 to rotate in the opposite direction, thereby automatically and orderly retracting the power cord wound on it, completing the automatic retraction action of the power cord.

[0020] In practical implementation, the lower surface of the rotary take-up reel 20 is provided with a spring clip mounting position 25, in which a rotary spring clip 251 is clipped. A lever connecting post 26 is provided on one side of the spring clip mounting position 25, and a rotary lever 261 is movably connected to the outer side of the lever connecting post 26. The rotary lever 261 is positioned between the two sides of the rotary spring clip 251. During use, when the rotary take-up reel 20 rotates as the power cord is pulled out or retracted, the rotary lever 261, driven by the lever connecting post 26, intermittently pushes or disengages relative to the rotary spring clip 251, allowing the rotary spring clip 251 to automatically engage and disengage according to the rotation direction and angle, thus providing damping, rotation limiting, and preventing excessive rotation. This structure effectively prevents the take-up reel from experiencing unstable cable retrieval due to excessively rapid release of spring force, while also improving safety and control accuracy.

[0021] In practical implementation, the front of the junction box base 10 is provided with a control panel mounting plate 17. One side surface of the control panel mounting plate 17 is provided with a storage box mounting position 171, and an external junction box 18 is fitted into the storage box mounting position 171. The external junction box 18 is correspondingly arranged with the inlet opening 12. During use, the control panel mounting plate 17 can be used to install the control panel of the electric heating table. Users can use the control panel on the control panel mounting plate 17 to operate the electric heating table such as powering on, heating, and temperature control. At the same time, the external junction box 18 is used to properly store the power plug, avoiding the plug from being exposed and causing collision, pollution, or tangling, thus improving the overall neatness and safety of storage.

[0022] In practical implementation, the outer side of the junction box base 10 is provided with several fixing through posts 19, and the outer side of the junction box cover 30 is provided with several fixing through ears 34. The fixing through ears 34 and the fixing through posts 19 correspond one-to-one, and are connected and fixed by fasteners passing through the fixing through ears 34 and fixing through posts 19, so that the junction box cover 30 is fixedly installed on the junction box base 10, which is convenient and stable.

[0023] In summary, the cable box base 10 has a recessed cable reel mounting groove 11, the rotating cable reel 20 is installed in the cable reel mounting groove 11, and the cable box cover 30 is installed on the cable box base 10. The rotating cable reel 20 has a winding ring 22 in the middle, and the cable box cover 30 has a cable outlet slot 31 in the middle. The cable outlet slot 31 is located at the upper end of the winding ring 22. A fixed cable code 23 is installed inside the winding ring 22. A rotating cable code 32 is installed on one end surface of the cable box cover 30, and a rotating coil 321 is provided in the middle of the rotating cable code 32. The automatic cable box of the electric heating table of this utility model can adapt to the movement angle of the power cord when it is pulled out or retracted, effectively reducing the risk of cable twisting and knotting, improving the smoothness and service life of the power cord, and has a simple structure, reducing structural complexity and manufacturing cost.
