Description
Technical Field
[0001] The utility model relates to the technical field of LED lamps, in particular to a pull-proof power cord for LED lamps. Background Art
[0002] LED lamps are lighting equipment that use LED as a light source. They are energy-saving, environmentally friendly, and have a long life. LED lamps are widely used in various fields such as home lighting and commercial lighting. They are available in various styles and colors, and the brightness and color temperature can be adjusted as needed. Compared with traditional lamps, LED lamps have good power saving effects, long service life, and reduce energy consumption and lamp replacement costs.
[0003] When the LED lamp is in use, the power cord needs to be connected to the power supply end. However, the power cord on the existing LED lamp is welded on the lamp board and then extended out. When the power cord of the LED lamp is pulled by external force, the power cord is easy to fall off the lamp board, making the LED lamp unusable. The power cord of the LED lamp has no anti-pull function and is easy to break. The LED lamp has poor practicality. Therefore, we propose a pull-proof power cord for LED lamps. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1:
[0020] See also Figure 1-3 The utility model provides a technical solution: a pull-proof LED lamp power cord, comprising an LED lamp body 1, a power cord 6 is connected inside the LED lamp body 1, a U-shaped seat 5 is installed on the outer wall of the LED lamp body 1, a driving shaft 7 is rotatably connected to the inner wall of the U-shaped seat 5, and the bottom end of the driving shaft 7 passes through the bottom wall of the U-shaped seat 5, a winding wheel 8 for winding the power cord 6 is provided on the driving shaft 7, an iron ring 9 is provided on the lower surface of the U-shaped seat 5, a rectangular sleeve 10 is slidably connected to the outer wall of the driving shaft 7, a locking assembly is provided between the rectangular sleeve 10 and the driving shaft 7, and a magnetic ring 11 matched with the iron ring 9 is provided on the upper surface of the rectangular sleeve 10.
[0021] The LED lamp body 1 is an existing device. The LED lamp body 1 is powered by a power cord 6. The rotation of the drive shaft 7 can drive the winding wheel 8 fixedly connected to the drive shaft 7 to rotate forward or reverse. The power cord 6 wound on the winding wheel 8 can be retracted or released. When the LED lamp is in use, it can effectively prevent the power cord from falling off the LED lamp after encountering a strong pull. The power cord of the LED lamp has an anti-pull function to prevent the power cord from being damaged after being pulled. When the LED lamp body 1 is in use, the locking block 15 is locked with the locking assembly. The locking hole 16 is connected, and the position of the rectangular sleeve 10 is fixed. At this time, the magnetic ring 11 is not attracted to the iron ring 9, and the driving shaft 7 can be rotated. After determining the length and usage position of the power cord 6, the locking block 15 is disengaged from the corresponding locking hole 16 through the locking assembly. At this time, the rectangular sleeve 10 can slide up, so that the magnetic ring 11 on the rectangular sleeve 10 is attracted to the iron ring 9, that is, the position of the driving shaft 7 is locked, preventing the winding wheel 8 from rotating, avoiding the power cord of the LED lamp from being loose when not in use, and improving the practicality of the LED lamp.
[0022] Among them, preferably, the inner wall of the LED lamp body 1 is provided with a circuit board 2, and the lower surface of the circuit board 2 is provided with multiple groups of LED lamp beads 3, the bottom of the circuit board 2 is provided with solder points compatible with the power cord 6, and the bottom of the LED lamp body 1 is installed with a lampshade 4.
[0023] Preferably, the locking assembly includes an operating rod 12, which is slidably connected to the right side wall of the rectangular sleeve 10, and a locking block 15 is installed at the bottom of the operating rod 12, and a locking hole 16 adapted to the locking block 15 is opened at the bottom end of the outer wall of the drive shaft 7.

The outer wall of the operating rod 12 is sleeved with a return spring 13, and the return spring 13 is located between the outer side surface of the auxiliary plate 14 and the inner wall of the rectangular sleeve 10; the right side of the inner cavity of the rectangular sleeve 10 is hollow. When the rectangular sleeve 10 needs to slide on the driving shaft 7, the operating rod 12 is pulled outward, and the auxiliary plate 14 is moved outward at this time, the return spring 13 is compressed, and the locking block 15 is away from the locking hole 16. At this time, the position of the rectangular sleeve 10 is no longer restricted, and the rectangular sleeve 10 can slide on the driving shaft 7. When the position of the rectangular sleeve 10 needs to be fixed, the locking block 15 is aligned with the locking hole 16, and the operating rod 12 is released. The compressed return spring 13 automatically returns to its original position, so that the locking block 15 is connected to the corresponding locking hole 16, thereby fixing the position of the rectangular sleeve 10 and the driving shaft 7.
[0025] Preferably, a pull ring is installed on the top of the operating rod 12, and the hand-held end of the pull ring is covered with an anti-skid rubber sleeve; the pull ring facilitates the pulling of the operating rod 12, and the anti-skid rubber sleeve plays an anti-skid role to prevent the hand from slipping when holding the pull ring.
