[0031] When the present invention is used, the locking component 4 is used to lock the installation component 1 and the lifting equipment chain, and the synchronous driving component 21 drives the multiple angle adjustment components 22 to synchronously adjust the angle. The warning spotlights 3 on the multiple angle adjustment components 22 are synchronously adjusted to adjust the angle, thereby changing the range of the warning circle composed of the multiple warning spotlights 3 to adapt to different warning needs.

[0032] In some embodiments, the mounting assembly 1 includes a sleeve 11, a slide groove 12, a shell 13 and a connecting ring 14. The slide groove 12 has multiple and evenly spaced grooves extending through the outer wall of the sleeve 11. The shell 13 is fixedly mounted on the top outer side of the sleeve 11. The connecting ring 14 is fixedly mounted on the bottom outer side of the sleeve 11. The sleeve 11 and the slide groove 12 are both connected to the synchronous drive assembly 21. The slide groove 12 and the connecting ring 14 are both connected to the angle adjustment assembly 22. The locking assembly 4 is mounted on the top of the shell 13. The locking assembly 4 is arranged on the top of the sleeve 11. Multiple angle adjustment assemblies 22 are distributed in a ring at equal intervals around the central axis of the sleeve 11.

[0033] The synchronous drive assembly 21 includes a worm gear 211, a worm 212, a ring platform 213, an arcuate groove 214, and a handle 215. The worm gear 211 is located inside the housing 13 and is rotatably mounted on the top outside of the sleeve 11. The worm 212 is rotatably mounted inside the housing 13. The worm gear 211 and the worm 212 are meshed and connected. One end of the worm 212 rotates through and extends to the outside of the housing 13 and is fixedly connected to the handle 215. The ring platform 213 is rotatably mounted on the outside of the sleeve 11 and is fixedly mounted on the bottom surface of the worm gear 211. A plurality of arcuate grooves 214 are evenly spaced on the bottom surface of the ring platform 213. The multiple arcuate grooves 214 and the bottom of the ring platform 213 form a continuous and smoothly transitioned wavy surface, which is in contact with the angle adjustment assembly 22.

[0034] The angle adjustment assembly 22 includes a slider 221, a slide post 222, a spring 223, a first connecting rod 224, and a second connecting rod 225. The slider 221 is arranged in a limited sliding connection within the chute 12. The slide post 222 is fixedly mounted on the side wall of the slider 221. The outer wall of the slide post 222 is in sliding contact with the wavy surface. One end of the spring 223 is fixedly connected to the bottom of the slider 221, and the other end of the spring 223 is fixedly connected to the inner bottom wall of the chute 12. The top of the first connecting rod 224 is hinged to the bottom side wall of the slider 221. The side wall of the first connecting rod 224 is hinged to one end of the second connecting rod 225. The other end of the second connecting rod 225 is hinged to the outer wall of the connecting ring 14. The warning spotlight 3 is fixedly mounted on the bottom of the first connecting rod 224. The warning spotlight 3 is a laser spotlight.

[0035] During use of the present invention, when adjusting the warning range of the warning spotlight 3, the handle 215 is rotated. The handle 215 drives the worm 212 to rotate, the worm 212 drives the worm gear 211 to rotate, the worm gear 211 drives the ring 213 to rotate, and the ring 213 drives the wavy surface at its bottom to rotate. The slide post 222 slides against the wavy surface, and the slide post 222 drives the slider 221 to slide within the slide groove 12. The slider 221 drives the first connecting rod 224 to move and rotate the first connecting rod 224 and the second connecting rod 225, thereby changing the illumination angle of the warning spotlight 3 located on the first connecting rod 224, thereby changing the warning range of the multiple warning spotlights 3. In addition, when the slider 221 moves downward, the warning range of the multiple warning spotlights 3 increases, and when the slider 221 moves upward, the warning range of the multiple warning spotlights 3 decreases.

[0036] In some embodiments, the locking assembly 4 includes a latch 41, an annular groove 42, a dome surface 43, an ear plate 44, a rotating shaft 45, a torsion spring 46, a locking block 47 and an arc-shaped locking groove 48. The latch 41 is plugged into two symmetrical through holes on the sleeve 11. An annular groove 42 is provided on the right side of the outer wall of the latch 41, and a dome surface 43 is provided on the right end of the latch 41. The two ear plates 44 are fixedly installed on the top of the shell 13 at intervals. A rotating shaft 45 is rotatably connected between the two ear plates 44. The outer end of the torsion spring 46 is fixedly connected to the ear plate 44, and the inner end of the torsion spring 46 is fixedly connected to the outer wall of the rotating shaft 45. One end of the locking block 47 is fixedly connected to the outer wall of the rotating shaft 45. The bottom surface of the other end of the locking block 47 is provided with an arc-shaped locking groove 48 for engaging with the annular groove 42. The outer wall of the dome surface 43 can be fitted and slidably connected with the inner wall of the arc-shaped locking groove 48.

[0037] When the present invention is used, the outer end of the chain of the lifting device is moved to the top interior of the sleeve 11. When the chain is in the appropriate position inside the sleeve 11, the latch 41 is inserted into the through hole on the left side of the sleeve 11 and passes through the hole on the chain. The dome surface 43 then passes through the through hole on the right side until the top side of the dome surface 43 contacts and slides against the inner wall of the arc-shaped locking groove 48. The inner wall of the arc-shaped locking groove 48 slides along the outer wall of the dome surface 43 into the annular retaining groove 42 and engages with the annular retaining groove 42. At this time, under the elastic force of the torsion spring 46, the annular retaining groove 42 and the arc-shaped locking groove 48 are locked. The locking block 47 needs to overcome the elastic force of the torsion spring 46 to drive the rotating shaft 45 to rotate. In addition, after the dome surface 43 passes through the through hole on the right side, the arc-shaped locking groove 48 can be lifted to allow the dome surface 43 to pass through, and then the inner wall of the arc-shaped locking groove 48 is in contact with the outer wall of the dome surface 43.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
