[0028] As Figures 1-5 The utility model provides a safety helmet for elevator operation, including safety helmet main part 5, the top of safety helmet main part 5 is connected with the sliding ring 7 through a plurality of connecting rods 8, and the upper and lower sides of the sliding ring 7 are both provided with sliding grooves 10.

[0029] Both sides of the inner end surface of the sliding sleeve 11 are provided with sliding blocks 15, the sliding sleeve 11 is sleeved on the outer end surface of the sliding ring 7, and the two sliding blocks 15 are respectively located inside the sliding grooves 10 on both sides, and the sliding blocks 15 on both sides are used.

[0030] A plurality of annular array distributed clamping grooves 12 are arranged in the upper sliding groove 10, and a plurality of abutting components matched with the clamping grooves 12 are arranged on the upper sliding block 15.

[0031] The utility model further includes a hinge 9, the side, away from the sliding sleeve 11, of the hinge 9 is provided with a mounting shell 4, the mounting shell 4 is provided with a camera body 2, and the opening of the mounting shell 4 is provided with a limiting component, and the camera angle of the camera body 2 can be adjusted through the hinge 9.

[0032] In the utility model, when in use, the staff wears the safety helmet main part 5, so that the staff can be protected.

[0033] When the camera body 2 needs to be installed, the limiting effect of the limiting component is cancelled first, then the camera body 2 is installed in the mounting shell 4, and then the camera body 2 is limited in the mounting shell 4 through the limiting component, so that the camera body 2 can be installed, and the current working condition can be shot through the camera body 2, and the camera angle of the camera body 2 can be adjusted through the hinge 9.

[0034] When the position of the mounting shell 4 needs to be adjusted, the sliding sleeve 11 can be slid on the sliding ring 7, and the sliding blocks 15 on both sides can be slid in the sliding grooves 10 on both sides, so that the stability of the sliding sleeve 11 is ensured.

[0035] When the sliding sleeve 11 slides on the sliding ring 7, the limiting ends of the plurality of abutting assemblies are clamped in the clamping grooves 12 at different positions to adjust the rotation angle of the sliding sleeve 11, so that the sliding sleeve 11 cannot slide on the sliding ring 7 at will.

[0036] In an optional embodiment, the limiting assembly includes a fixing bolt 1 and a top cover 6. The top cover 6 is hinged to the opening of the mounting shell 4. The fixing bolt 1 is symmetrically distributed and penetrates through the top cover 6 and extends into the mounting shell 4. The mounting shell 4 is in threaded connection with the fixing bolt 1.

[0037] It should be noted that when the camera body 2 needs to be taken out from the inside of the mounting shell 4, the fixing bolts 1 on both sides are rotated to take them off, and then the top cover 6 is turned over to take the camera body 2 out from the inside of the mounting shell 4. When the camera body 2 needs to be installed, the top cover 6 is turned over, the camera body 2 is installed in the inside of the mounting shell 4, the top cover 6 is turned over in the opposite direction, and finally the fixing bolts 1 on both sides are rotated to fix the top cover 6 and the mounting shell 4.

[0038] In an optional embodiment, the limiting assembly includes a fixing bolt 1 and a top cover 6. The top cover 6 is hinged to the opening of the mounting shell 4. The fixing bolt 1 is symmetrically distributed and penetrates through the top cover 6 and extends into the mounting shell 4. The mounting shell 4 is in threaded connection with the fixing bolt 1.

[0039] It should be noted that the two-sided extraction grooves 3 facilitate the staff to take the camera body 2 out from the inside of the mounting shell 4.

[0040] In an optional embodiment, the abutting assembly includes a hole 16, a spring 13 and a clamping block 14. The hole 16 is multiple and equidistantly arranged on the upper slider 15.

The distance between the adjacent two holes 16 is the same as the distance between the adjacent two clamping grooves 12. The plurality of clamping blocks 14 abut with the plurality of clamping grooves 12 matched therewith, wherein the clamping groove 12 is a semicircular ball.

[0041] It should be noted that when the sliding sleeve 11 needs to be driven to slide on the sliding ring 7, the plurality of clamping blocks 14 will move out of the clamping grooves 12 abutting therewith. At this time, the spring 13 is compressed and shrinks, so that the clamping block 14 shrinks into the hole 16. When the clamping block 14 moves to the next clamping groove 12, the spring 13 is elongated, so that the clamping block 14 connected therewith abuts with the clamping groove 12 matched therewith. The clamping block 14 is clamped in the clamping groove 12 at different positions to adjust the rotation angle of the sliding sleeve 11, so that the use angle of the camera body 2 can be adjusted, and the applicability is improved.

[0042] In an alternative embodiment, the sliding sleeve 11 is provided with a slot on the side edge, the connecting rod 8 is located in the slot, and the diameter of the connecting rod 8 is smaller than the distance of the slot.

[0043] It should be noted that the multiple connecting rods 8 can stably support and fix the sliding ring 7, and since the connecting rod 8 is located in the slot and has a diameter smaller than the distance of the slot, the sliding sleeve 11 can slide on the sliding ring 7.

[0044] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
