Abstract
Description
Technical Field
[0001] This utility model relates to the field of power safety technology, specifically to a power safety warning light strip. Background Technology
[0002] Power safety warning light strips are flexible luminous warning devices that use LED beads arranged in a strip, combined with a high-strength shell and warning signs. They are used for warning of dangerous areas, indicating equipment status, and providing safety reminders in power facilities. By placing the light strip around high-voltage equipment, the continuous flashing of the light strip alerts personnel to their presence. At the same time, different colors or flashing frequencies indicate the operating status of the equipment, providing visual guidance for workers at night or in low-light conditions.
[0003] For example, Chinese patent CN216864924U, entitled "A Warning Tape Device with Warning Light," includes a main body with a circumferential side and a display plane, the circumferential side and the display plane being perpendicularly arranged, and a pull-out opening on the circumferential side allowing the warning tape to enter and exit; a warning light, located on the display plane of the main body, emitting light to serve as an alarm; a switch on the main body connected to the warning light circuit; a battery compartment on the main body, the warning light connected to the battery circuit; the main body being a turntable, with a winding reel extending from the central axis of the turntable toward the display plane; the turntable being made of ABS material; and a pull-out ring located outside the pull-out opening, connected to the warning tape, the pull-out ring having a through hole allowing a finger to pass through, and the size of the pull-out ring being larger than the size of the pull-out opening.
[0004] While the aforementioned existing technologies can enable the use of LED strips, in practical applications, on the one hand, the LED strip winding is not convenient enough, usually requiring manual winding to wrap the LED strip onto the winding drum, thus reducing the efficiency of LED strip winding; on the other hand, it is difficult to fix the stretched LED strip, usually after the LED strip is unfolded, it will slightly rewind under the interference of external forces, causing the operator to need to adjust the position of the LED strip, thus reducing the user experience of the LED strip. Therefore, it does not meet the current needs. In response, we propose an electrical safety warning LED strip. Utility Model Content
[0005] The purpose of this utility model is to provide an electrical safety warning light strip to solve the problems mentioned in the background art, such as the inconvenience of rewinding the light strip and the difficulty in fixing the stretched light strip.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a power safety warning light strip, comprising an outer shell, of which two shells are provided. A fixing rod is provided at the center of the interior of each shell. The front and rear ends of the fixing rod are fixedly connected to the two shells. A winding drum is provided on the outer side of the fixing rod. An installation cavity is provided at the center of the interior of the winding drum. The winding drum is sleeved on the outside of the fixing rod through the installation cavity. A rotary spring is fixedly provided on the outside of the fixing rod. The other end of the rotary spring is fixedly connected to the winding drum. A light strip body is wound around the outside of the winding drum. One end of the light strip body extends to the outside of the outer shell.
[0007] Preferably, the outer shell has a limiting cavity inside the side near the take-up drum. The limiting cavity is an open structure. The front and rear ends of the take-up drum are fixedly provided with a retaining plate. One end of the retaining plate extends into the interior of the limiting cavity, and the retaining plate slides and limits the limiting cavity.
[0008] Preferably, the winding drum has four first through holes inside the outer side of the light strip body. The first through holes are distributed in a ring at equal intervals and have a through structure. The outer shell has several second through holes inside the outer side of the limiting cavity. The second through holes are distributed in a ring at equal intervals and correspond to the positions of the first through holes.
[0009] Preferably, a plug is provided on the lower part of the outer shell, the front end of the plug extends into the interior of the shell through the first through hole and the second through hole, and a fixing hook is fixedly provided on both the upper and lower parts of the front end of the plug, the front end of the fixing hook extends into the exterior of the shell through the second through hole, and the fixing hook is engaged and fixed with the shell.
[0010] Preferably, a limiting seat is fixedly provided on one side above the housing, and the limiting seat has a sliding groove inside. The sliding groove has a through structure, and the light strip body passes through the limiting seat through the sliding groove.
[0011] Preferably, a snap-fit seat is fixedly provided at one end of the light strip body, and the snap-fit seat is in contact with the limiting seat.
[0012] Preferably, a connecting rod is provided at the center of the outer shell, and a handle is fixedly provided on the outside of the connecting rod, extending to the top of the outer shell.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model can drive the take-up drum to rotate through the rotary spring and the snap-fit disc. When it is necessary to stretch the light strip, first pull the plug out of the second through hole to release the fixation of the take-up drum. At this time, the operator holds the snap-fit seat and pulls it. The snap-fit seat drives the light strip body fixedly connected to it to move outside the take-up drum. At the same time, the snap-fit discs at both ends of the take-up drum rotate inside the limiting cavity, and the rotary spring is in the stretched state until the light strip body is stretched to a suitable length and put into use. When winding the light strip body, release the snap-fit seat. At this time, the rotary spring resets. The reset of the rotary spring drives the take-up drum to rotate between the outer shells. At the same time, the stretched light strip body is wrapped around the outside of the take-up drum until the rotary spring completes the reset. At this time, the snap-fit seat contacts the limiting seat, thereby improving the convenience of light strip winding.
[0015] (2) This utility model can fix the stretched light strip body through the second through hole and the insert rod. When it is necessary to fix the light strip, the light strip body has been stretched to a suitable length. At this time, the operator aligns the insert rod with the appropriate second through hole opening and inserts it into the second through hole. At the same time, the elastic fixing hook on the insert rod extends to the outside of the outer shell through the first through hole. When the fixing hook passes through the first through hole and the second through hole, it is in a compressed state. When the fixing hook extends to the outside of the outer shell, the fixing hook is reset and locked with the outer shell, thus completing the fixing of the winding drum. This avoids the situation where the light strip body is wound up due to external force interference, thereby improving the user experience of the light strip body.
[0016] (3) This utility model can maintain the stability of the light strip body during the stretching and winding process by using the limiting seat and the sliding groove. When the light strip is being wound up, the light strip body slides in the sliding groove inside the limiting seat. The limiting seat maintains the stability of the light strip body during the winding process and prevents it from shifting or deviating from the predetermined winding path. At the same time, the light strip body passes through the limiting seat, so the light strip body can maintain a more stable state during winding, reducing the phenomenon of uneven winding or tangling caused by shaking or deviation, and avoiding quality problems caused by loosening or uneven winding of the light strip during the winding process.

The handle 2 extends to the top of the housing 1.
[0024] Please see Figure 1 , Figure 2 and Figure 3 An installation cavity 14 is provided at the center of the inside of the take-up drum 4. The take-up drum 4 is sleeved on the outside of the fixing rod 12 through the installation cavity 14. A rotary spring 13 is fixedly installed on the outside of the fixing rod 12. The other end of the rotary spring 13 is fixedly connected to the take-up drum 4. A light strip body 7 is wound around the outside of the take-up drum 4. One end of the light strip body 7 extends to the outside of the outer shell 1. A limiting cavity 16 is provided inside the outer shell 1 on the side close to the take-up drum 4. The limiting cavity 16 is an open structure. A retaining plate 17 is fixedly installed at both the front and rear ends of the outside of the take-up drum 4. One end of the retaining plate 17 extends into the inside of the limiting cavity 16. The retaining plate 17 slides and limits the limiting cavity 16, so that the light strip body 7 can be wound up by the rotary spring 13.
[0025] Please see Figure 1 , Figure 3 and Figure 4The take-up drum 4 is located inside the outer side of the light strip body 7 and has four first through holes 8. The first through holes 8 are distributed in a ring at equal intervals and are through-holes. The outer shell 1 is located inside the outer side of the limiting cavity 16 and has several second through holes 9. The second through holes 9 are distributed in a ring at equal intervals and correspond to the positions of the first through holes 8. A rod 11 is provided at the lower part of the outer shell 1. The front end of the rod 11 extends into the inner side of the outer shell 1 through the first through holes 8 and the second through holes 9. Fixing hooks 10 are fixedly provided above and below the front end of the rod 11. The front end of the fixing hooks 10 extends into the outer side of the outer shell 1 through the second through holes 9 and is engaged with the outer shell 1 to fix the take-up drum 4.
[0026] Please see Figure 1 and Figure 2 A limiting seat 5 is fixedly installed on one side above the outer shell 1. The limiting seat 5 has a sliding groove 15 inside. The sliding groove 15 has a through structure, and the light strip body 7 passes through the limiting seat 5 through the sliding groove 15, so as to maintain the stability of the light strip body 7 during winding through the limiting seat 5.
[0027] Working principle: In use, first pull the plug 11 out of the second through hole 9 to release the fixing of the take-up drum 4. At this time, the operator holds the locking seat 6 and pulls it. The locking seat 6 drives the LED strip body 7, which is fixedly connected to it, to move outside the take-up drum 4.

When winding the LED strip body 7, release the locking seat 6. At this time, the rotary spring 13 returns to its original position. The return of the rotary spring 13 drives the take-up drum 4 to rotate between the outer shell 1. At the same time, the stretched LED strip body 7 is wrapped around the outside of the take-up drum 4 until the rotation ends. Spring 13 completes its reset. At this time, the snap-fit seat 6 contacts the limit seat 5, and the light strip body 7 slides in the groove 15 inside the limit seat 5. When it is necessary to fix the light strip body 7, the light strip body 7 has been stretched to a suitable length. At this time, the operator aligns the plug rod 11 with the appropriate second through hole 9 opening and inserts it into the second through hole 9. At the same time, the elastic fixing hook 10 on the plug rod 11 extends to the outside of the outer shell 1 through the first through hole 8. When the fixing hook 10 passes through the first through hole 8 and the second through hole 9, it is in a compressed state. When the fixing hook 10 extends to the outside of the outer shell 1, the fixing hook 10 resets and snaps into the outer shell 1, thus completing the fixation of the take-up drum 4.
