[0016] The following will further explain the present invention in conjunction with the appended Figure 1 to the appended Figure 5 drawings.

[0017] An embedded plug box and a lower-outlet coiling machine include: a box body 1 with a cavity inside, in which a reel 18 is rotatably installed through a rotating mechanism, and the axis of the reel 18 is horizontally arranged along the left-right direction; a power mechanism arranged in the box body 1 for driving the reel 18 to rotate; a cable outlet 2 arranged at the lower end of the box body 1, and the length of the cable outlet 2 matches the axial length of the reel 18; a spiral groove 22 is spirally arranged along the axis on the reel 18, one end of a cable 3 is wound in the spiral groove 22 of the reel 18, and the other end thereof extends out of the box body 1 through the cable outlet 2 and is connected with an aviation plug 4. The power mechanism drives the reel 18 to rotate forward or backward through the rotating mechanism. Since the cable 3 is wound in the spiral groove 22 of the reel 18, the cable 3 can be wound in or unwound from the reel 18 by the forward or reverse rotation of the reel 18. Since the cable outlet 2 is arranged at the lower end of the box body 1, more preferably, the cable outlet 2 is located on the horizontal tangent line at the lower end of the reel 18. Therefore, the cable 3 wound in the spiral groove 22 can extend out of the box body 1 through the cable outlet 2. Since the lower-outlet method is adopted, there is no height difference between the cable 3 and the ground. At the same time, the lower cable outlet located on the horizontal tangent line at the lower end of the reel 18 further reduces the space waste of the cable 3 and increases the effective use length of the cable 3.

[0018] In an embodiment of the present invention, the rotating mechanism includes a support shaft Ⅰ 19 coaxially installed at the left end of the reel 18 and a support shaft Ⅱ 20 coaxially installed at the right end of the reel 18. The support shaft Ⅰ 19 is rotatably connected to the left end of the box body 1, and the support shaft Ⅱ 20 is rotatably connected to the right end of the box body 1. The reel 18 can rotate in the box body 1 through the support shaft Ⅰ 19 and the support shaft Ⅱ 20, thereby realizing the winding and unwinding of the cable 3.

[0019] In one embodiment of the present invention, the power mechanism includes a speed reducer 21 and a motor 10 mounted on the box body 1. The output shaft of the motor 10 is coaxially and drivingly connected to the input shaft of the speed reducer 21, and the output shaft of the speed reducer 21 is coaxially and drivingly connected to the support shaft II 20. When the motor 10 operates, it drives the drum 18 to rotate after reducing and amplifying the torque through the speed reducer 21. The structure is simple and the operation is reliable.

[0020] In one embodiment of the present invention, the helix direction of the spiral groove 22 is right-handed. The spiral groove 22 is set to be right-handed. Therefore, when the speed reducer 21 rotates clockwise, the drum 18 rotates clockwise, thus releasing the cable 3. When the speed reducer 21 rotates counterclockwise, the drum 18 rotates counterclockwise, thus retracting the cable 3.

[0021] In one embodiment of the present invention, it further includes a fixing device arranged on the box body 1. The aviation plug 4 is fixed to the box body 1 through the fixing device. By arranging the fixing device, it is convenient to fix the aviation plug 4 to the box body 1, which is convenient for storage.

[0022] In this embodiment, preferably, the fixing device includes a plug slot 5 arranged at the upper end of the box body 1 and a support plate 6 rotatably mounted on the box body 1 through a hinge 9. The inner diameter of the plug slot 5 matches the outer diameter of the aviation plug 4. The support plate 6 is located at the lower end of the plug slot 5. A U-shaped opening 11 is arranged in the support plate 6. The width of the U-shaped opening 11 matches the outer diameter of the cable 3. When the aviation plug 4 is inserted into the plug slot 5, the support plate 6 rotates upward until the cable 3 is inserted into the U-shaped opening 11. The support plate 6 holds the aviation plug 4 by embedding the cable 3 into the U-shaped opening 11, ensuring that its head end is located in the plug slot 5. When the aviation plug 4 is pulled outwards, the support plate 6 rotates downward, so that the cable 3 disengages from the U-shaped opening 11 of the support plate 6, thus realizing the removal operation of the aviation plug 4. The removal and storage operation of the aviation plug is convenient.

[0023] In one embodiment of the present invention, it further includes a groove 7 arranged in the box body 1. The inner diameter of the groove 7 matches the outer diameter of the support plate 6. When the support plate 6 rotates downward to the vertical state, it is embedded in the groove 7.

[0024] In one embodiment of the present invention, it further includes a Y-shaped opening 12 arranged at the front end of the U-shaped opening 11. The width of the Y-shaped opening 12 is greater than the outer diameter of the cable 3. After the aviation plug 4 is taken out from the plug slot 5, the support plate 6 rotates downward and flips to be embedded in the groove 7. The support plate 6 is flush with the front end surface of the box body 1, which plays a role in storing the support plate 6 and also improves the overall aesthetics of the equipment.

[0025] In an embodiment of the present invention, it further includes a cover plate 8. L-shaped guide grooves 13 are respectively arranged at the left and right ends of the cover plate 8, and mounting holes 17 are respectively arranged on the left and right sides of the upper end of the cover plate 8. A screw I 15 passes through the guide groove 13 and is screwed into the box body 1 at the lower end of the wire outlet 2. When the screw I 15 is at the uppermost end of the vertical section of the guide groove 13, the cover plate 8 slides downward until the wire outlet 2 is exposed. When the screw I 15 is at the rightmost end of the horizontal section of the guide groove 13, the cover plate 8 slides upward to close the wire outlet 2. A screw II 16 passes through the mounting hole 17 and is screwed into the box body 1 at the upper end of the wire outlet 2. When the reel 18 rotates to wind and unwind the cable 3, after loosening the screw II 16, the cover plate 8 is first pushed to the right. The screw I 15 plays a guiding role in the guide groove 13 and slides from the horizontal section of the guide groove 13 to the vertical section. Then, the cover plate 8 is moved downward, and the screw I 15 slides within the vertical section of the guide groove 13. The cover plate 8 moves to the lowermost end. At this time, the wire outlet 2 is completely exposed, facilitating the winding and unwinding of the cable 3. After use, the cover plate 8 is moved upward, the screw I 15 moves to the lowermost end within the vertical section, and then the cover plate 8 is moved to the left. The screw I 15 moves to the rightmost end within the horizontal section, and the cover plate 8 closes the wire outlet 2, preventing mice from entering the box body 1 through the wire outlet 2 and damaging the cable 3, further improving the safety of the use of the reel machine. Finally, the screw II 16 is passed through the mounting hole 17 and screwed into the box body 1 at the upper end of the wire outlet 2 to lock and fix the cover plate 8 relative to the box body, preventing it from falling off.

[0026] In this embodiment, preferably, a handle 14 is installed on the cover plate 8. The handle 14 can facilitate the driving of the cover plate 8 to move, further improving the convenience of use.
