[0003] Currently, when installing the ceiling, most of them are supported manually by hand, which is not only laborious, but also there is a risk of the ceiling board falling or personnel being injured; or machines or other equipment are used as the support for the ceiling board, but the position needs to be moved frequently, which is extremely inconvenient and increases the installation period.

[0004] Chinese Patent CN 107772603 A discloses a safety helmet with anti-smashing function. This kind of safety helmet includes ventilation holes, an outer shell, a brim, a fixing band, a lacing, a plastic shell, a wire mesh, a first connecting plate, a first spring, a sliding rod, a baffle, a second spring, a sponge layer, a support plate, a second connecting plate, a bump, a rotating shaft, a first groove, a second groove, a sliding groove and a pulley. When the safety helmet is impacted by sundries, the plastic shell will move downward, and then the pulley will move upward in the sliding groove, reducing the impact force of the sundries on the safety helmet. When the impact of the sundries on the safety helmet is too large, when the pulley moves to the top of the sliding groove and the safety helmet still has to bear a huge impact, the wire mesh will press down the sliding rod, and then the sliding rod will rotate downward around the rotating shaft, and then compress the first spring, thereby reducing the impact force of the sundries on the safety helmet, and thus protecting the worker's head. However, the safety helmet of this application only has the anti-smashing function and has a single function, and it cannot support the ceiling board during ceiling installation. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 , Figure 1 is a schematic diagram of the structure of a safety helmet for assisting in ceiling installation provided by an embodiment of the present invention. In Figure 1 , this kind of safety helmet for assisting in ceiling installation includes a body 1 and a lifting device 2 installed on the body 1;

[0026] The lifting device 2 is used to lift and lower the ceiling board, and includes a lifting tabletop 24 for placing the ceiling board, a first folding structure 25 and a second folding structure 26 hinged to the body 1, and a pull rope 23 fixedly connected to the first folding structure 25; wherein, a spring is sleeved outside the pull rope 23 located between the first folding structure 25 and the second folding structure 26;

[0027] After the ceiling board is placed on the lifting tabletop 24, pull the pull rope 23, and then pull the first folding structure 25. At the same time, the spring limited between the first folding structure 25 and the second folding structure 26 is compressed, raising the lifting tabletop and thus lifting the ceiling board;

[0028] When the pull rope 23 is relaxed, the spring rebounds, causing the lifting tabletop 24 to descend, and then lowering the ceiling board.

[0029] Specifically, as Figure 1 shown, the main body 1 is hemispherical and can be made of fiberglass, polycarbonate plastic, ABS plastic, ultra-high molecular weight polyethylene plastic, modified polypropylene plastic, etc., but not limited thereto.

[0030] A brim 11 is provided at the front end of the hemispherical main body 1. When wearing the safety helmet, the hemispherical main body 1 can protect the head of the construction worker, and the brim 11 is convenient for protecting the eyes of the construction worker. A lighting lamp 12 is also installed above the brim 11. Through the function of the lighting lamp 12, it is convenient for the construction worker to observe the environment of the construction site without the need for others to provide lighting, and the structure is simple and reliable.

[0031] The lifting device 2 is arranged at the top of the main body 1 to control the lifting of the ceiling board, including a pulley 21 and a pull rope 23 wound around the pulley 21; the pulley 21 is fixedly installed on one side surface of the main body 1, and a rocker 22 is rotatably installed on the side of the pulley 21 away from the main body 1. By rotating the rocker 22, the pulley 21 can be driven to rotate, thereby pulling the pull rope 23 to move; the rocker 22 can be folded. When the height of the lifting device 2 does not need to be adjusted or the ceiling board is installed, the rocker 22 can be folded to avoid collision with surrounding walls or objects, and the fixed pull rope 23 does not move. The lifting device 2 further includes a first folding structure 25 formed by hinging a first web member 251 and a second web member 252 and a second folding structure 26 formed by hinging a third web member 261 and a fourth web member 262; the first folding structure 25 and the second folding structure 26 are respectively in a V shape, and the open ends of the first folding structure 25 and the second folding structure 26 are arranged facing each other to ensure the stability of the entire device.

[0032] The draw rope 23 passes through the hinge seam at the hinge part between the third web member 261 and the fourth web member 262 in the second folding structure 26, that is, the closed end of the "V" - shaped structure, and extends to the first folding structure 25, and is fixedly connected to the hinge shaft between the first web member 251 and the second web member 252. A spring (not shown in the figure) is sleeved outside the draw rope 23 located between the first folding structure 25 and the second folding structure 26. When the draw rope 23 is pulled and wound around the pulley 21, under the pulling force of the draw rope 23, the first folding structure 25 rotates relatively on the body 1. At the same time, the spring sleeved on the draw rope 23 is limited between the first folding structure 25 and the second folding structure 26 and is thus compressed. The opening of the first folding structure 25 and the second folding structure 26 in the shape of "V" increases, so that the lifting device 2 rises. When pulling the draw rope 23, in order to avoid the situation that the force on the first folding structure 25 is much greater than that on the second folding structure 26 due to excessive force, resulting in an uneven lifting table surface, the draw rope 23 should be pulled slowly, and the ceiling board should be gently supported by hand during pulling to ensure the smooth rise of the ceiling board.

[0033] When the draw rope 23 wound around the pulley 21 is released, the length of the draw rope 23 becomes relatively longer. At this time, the compressed spring gradually rebounds. Under the combined action of the gravity of the ceiling board and the elastic force of the spring, the included angle formed by the first web member 251 and the second web member 252 and the included angle formed by the third web member 261 and the fourth web member 262 decrease, thereby controlling the descent of the lifting device 2.

[0034] The draw rope 23 can be a polyester braided rope, a steel wire rope, a nylon rope, etc., but is not limited thereto.

[0035] The lifting table surface 24 installed on the lifting device 2 is used to place the ceiling board. By controlling the lifting of the lifting device 2, the position of the ceiling board is adjusted to realize the flexible installation of the ceiling board. The second web member 252 and the fourth web member 262 are respectively hinged to the lifting table surface 24. In order to keep the lifting table surface 24 horizontal and avoid the ceiling board from falling due to tilting, causing material damage or personal injury, the lengths of the first web member 251 and the third web member 261 are equal, and the lengths of the second web member 252 and the fourth web member 262 are equal.

[0036] On one side of the third web member 261 close to the pulley 21, an auxiliary pulley 27 is hinged by a hinge rod to support the draw rope 23 and play a buffering role to avoid the draw rope 23 from breaking due to friction during movement.

[0037] When installing the ceiling board, first put on the safety helmet provided in this embodiment, and then place the ceiling board on the lifting table 24 (at this time, both the worker and the ceiling board are already on the installation frame). By the movement of the installer, the ceiling board is moved horizontally. Then, turn the rocker 22 by hand. When turning clockwise, it will cause the rotation of the pulley 21, and then the pulling rope 23 is wound around the pulley 21. The pulling rope 23 is tightened. At this time, the spring sleeved on the pulling rope 23 is compressed because it is limited between the first folding structure 25 and the second folding structure 26, thereby causing the included angles of the first folding structure 25 and the second folding structure 26 to increase simultaneously, making the lifting table 24 rise and lifting the ceiling board. When turning the rocker 22 counterclockwise, the pulley 21 rotates in the reverse direction, and the pulling rope 23 wound around the pulley 21 unwinds to the relaxed state. At this time, the compressed spring will gradually bounce back, causing the included angles of the first folding structure 25 and the second folding structure 26 to decrease, thereby driving the lifting table 24 to descend, and the ceiling board follows to descend, thus realizing the adjustment of the ceiling board in the vertical direction. The safety helmet provided by the embodiment of the present invention can not only assist in the ceiling installation, enabling the installer to achieve flexible support and installation of the ceiling board, but also play a role in protecting the installer's own safety during the ceiling installation.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
