Description

Technical Field

[0001] This utility model belongs to the field of safety helmet technology, and specifically relates to a safety helmet with adjustable lighting angle. Background Technology

[0002] A safety helmet is a type of personal protective equipment used to protect the head. It typically consists of a sturdy outer shell and an inner liner and is designed to reduce the risk of head injury in accidents. In the industrial and construction sectors, safety helmets are essential personal protective equipment.

[0003] To facilitate workers' work in poor lighting conditions such as at night or underground in mines, safety helmets are usually equipped with integrated lights to make it easier for workers to carry out their work. Moreover, to adapt to different working conditions and environments, some safety helmets are usually equipped with adjustable lights.

[0004] For example, Chinese patent application number CN202421542888.7 discloses an engineering safety helmet, which has a U-shaped frame connected to one side of the helmet body. A crossbar is set on the U-shaped frame. The lighting unit is installed on the crossbar through a connecting block and fixed by two pressure plates threaded to the crossbar. A box is set on one side of the U-shaped frame. One end of the crossbar passes through the U-shaped frame and is inserted into the box. A disc is set at one end of the crossbar inside the box. Several limiting holes are set on the outside of the disc. A vertical rod is set on the box. A handle is set at the upper end of the vertical rod. A pair of springs are set between the handle and the box. A limiting block is set at the lower end of the vertical rod. The positioning block is inserted into the limiting hole to restrict the rotation of the horizontal bar, thereby fixing the illumination angle of the lighting body. When it is necessary to adjust the illumination angle of the lighting body, the handle is pulled up, and the positioning block is driven away from the limiting hole by the vertical rod. Keep the handle pulled up and adjust the lighting body to the required angle. Release the handle, and the positioning block is driven by the spring to re-insert into the limiting hole, thus completing the lighting angle adjustment. However, in the above technical solution, the operator needs to operate with both hands at the same time to complete the adjustment of the illumination angle of the lighting body. The operation process is complicated, resulting in extremely inconvenient and inefficient adjustment of the illumination angle. Utility Model Content

[0005] The purpose of this invention is to provide a safety helmet with an adjustable illumination angle, thereby overcoming the technical problems in existing technologies where adjusting the illumination angle requires simultaneous operation of both hands, resulting in a complex operation process, inconvenient adjustment of the illumination angle, and low adjustment efficiency. The specific technical solution is as follows:

[0006] An adjustable lighting angle safety helmet includes a safety helmet body and a strap located at the bottom end of the safety helmet body. An angle adjustment device and a lighting lamp are provided on the front side of the safety helmet body.

[0007] The angle adjustment device includes a U-shaped mounting plate, a rotating sleeve, a lamp holder, a rotating inner rod, and a regular polygonal fixing block. The lighting lamp is mounted on the lamp holder, which is in turn mounted on the rotating sleeve. A rotating through hole is provided through the U-shaped mounting plate, and the rotating sleeve is rotatably mounted on the rotating through hole. A polygonal stepped groove is provided on the opposite side of the rotating through hole. Sliding cavities are provided at both opposite ends of the rotating sleeve, and the rotating inner rod is slidably mounted in the sliding cavity. A return spring is provided in the sliding cavity, with one end connected to the bottom of the sliding cavity and the other end connected to the rotating inner rod. The regular polygonal fixing block is located near the end of the rotating inner rod and is adapted to the polygonal stepped groove. The rotating sleeve is fixed to the U-shaped mounting plate by means of the regular polygonal fixing block.

[0008] Preferably, the sliding cavity is provided with a sliding groove, and the rotating inner rod is provided with a slider that matches the sliding groove.

[0009] Preferably, the U-shaped mounting plate is further provided with a fixing seat, and the fixing seat is provided with a rotating bearing for supporting the rotating sleeve.

[0010] Preferably, the safety helmet body is provided with an arc-shaped protrusion, the arc-shaped protrusion is provided with a T-shaped groove, a T-shaped slider is slidably disposed in the T-shaped groove, the U-shaped mounting plate is mounted on the T-shaped slider, a plurality of adjustment through holes are provided on both sides of the arc-shaped protrusion, and elastic locking keys adapted to the adjustment through holes are provided on the opposite sides of the T-shaped slider.

[0011] Preferably, the arc-shaped protrusion is provided with a disassembly groove, which communicates with the T-shaped sliding groove.

[0012] Preferably, the end of the rotating inner rod away from the rotating sleeve is provided with a fingertip groove, and a rubber pad is provided on the fingertip groove.

[0017] Compared with existing technologies, this utility model has the following beneficial effects:

[0018] This utility model provides an adjustable lighting angle safety helmet. When it is necessary to change the illumination angle of the light, the operator only needs to use two fingers to press the two rotating inner rods against the rotating sleeve to release the spring, causing the regular polygonal fixing block and the polygonal stepped groove to separate. This allows adjustment of the illumination angle. When the illumination angle is adjusted to the appropriate angle, the two fingers are released, and the rotating inner rods return to their original position under the action of the return spring. The regular polygonal fixing block re-embeds into the polygonal stepped groove, thus fixing the illumination angle. This adjustment method is convenient and quick, solving the technical problem in the prior art where adjusting the lighting angle requires two hands simultaneously, resulting in a complex operation process, inconvenient adjustment of the illumination angle, and low adjustment efficiency.

[0030] Example

[0031] like Figures 1 to 4As shown, this embodiment of the utility model provides an adjustable lighting angle safety helmet, including a helmet body 100 and a strap 200. The strap 200 is connected to the bottom end of the helmet body 100 and is used to fasten to the worker's chin. An angle adjustment device 300 and a lighting lamp 400 are provided on the front side of the helmet body 100. The lighting lamp 400 is a rechargeable lithium battery headlamp.

[0032] Preferably, the angle adjustment device 300 includes a U-shaped mounting plate 310, a rotating sleeve 320, a lamp holder 330, a rotating inner rod 340, and a regular polygonal fixing block 350. The lighting lamp 400 is mounted on the lamp holder 330, and the lamp holder 330 is mounted on the rotating sleeve 320. A rotating through hole 311 is provided through the U-shaped mounting plate 310. The rotating sleeve 320 is rotatably mounted on the rotating through hole 311. A polygonal stepped groove 312 is provided on the opposite side of the rotating through hole 311. Sliding cavities 321 are provided at both opposite ends of the rotating sleeve 320. The rotating inner rod 340 is slidably disposed within the sliding cavity 321. A return spring 322 is disposed within the sliding cavity 321, with one end connected to the bottom of the sliding cavity 321 and the other end connected to the rotating inner rod 340. A regular polygonal fixing block 350 is disposed near the end of the rotating inner rod 340. The regular polygonal fixing block 350 is adapted to the polygonal stepped groove 312. By engaging the regular polygonal fixing block 350 within the polygonal stepped groove 312, the rotating sleeve 320 is fixed to the U-shaped mounting plate 310. (A bearing is disposed on the rotating through hole 311 away from the polygonal stepped groove 312. The rotating inner rod 340 is connected to the inner ring of the bearing to allow the rotating inner rod 340 to rotate on the U-shaped mounting plate 310. When the regular polygonal fixing block 350 is embedded in the polygonal stepped groove 312, it restricts the rotation of the rotating inner rod 340.)

[0033] In some preferred embodiments, a groove 323 is provided within the sliding cavity 321, and a slider 341 adapted to the groove 323 is provided on the rotating inner rod 340. The cooperation between the slider 341 and the groove 323 ensures stability during rotation and prevents angular differences between the regular polygonal fixing blocks 350 at opposite ends of the rotating sleeve 320, which could cause the rotating sleeve 320 to be unstablely fixed on the U-shaped mounting plate 310. Furthermore, the groove 323 does not extend to the opening of the sliding cavity 321 to prevent the rotating inner rod 340 from slipping out of the rotating sleeve 320. A fingertip groove 342 is provided at the end of the rotating inner rod 340 away from the rotating sleeve 320. A rubber pad is provided on the fingertip groove 342. By providing the fingertip groove 342, it is easier for the worker's fingers to press the rotating inner rod 340 better and at the same time drive the rotating inner rod 340 to rotate, so as to drive the lighting lamp 400 to rotate and adjust the illumination angle. The rubber pad is used to increase the friction between the rotating inner rod 340 and the worker's fingers.

[0034] In some preferred embodiments, the fixed base 313 is provided with a rotating bearing for supporting the rotating sleeve 320, and the rotating sleeve 320 passes through the rotating bearing. By providing the fixed base 313 and the rotating bearing on the U-shaped mounting plate 310, and by ensuring an interference fit between the rotating sleeve 320 and the rotating bearing, axial movement of the rotating sleeve 320 can be prevented when adjusting the angle of the lighting lamp 400.

[0035] In some preferred embodiments, the helmet body 100 is provided with an arc-shaped protrusion 110, the arc-shaped protrusion 110 is provided with a T-shaped groove 111, a T-shaped slider 120 is slidably disposed in the T-shaped groove 111, the U-shaped mounting plate 310 is mounted on the T-shaped slider 120, a plurality of adjustment through holes 112 are provided on both sides of the arc-shaped protrusion 110, and elastic locking keys 130 adapted to the adjustment through holes 112 are provided on the opposite sides of the T-shaped slider 120. By setting the arc-shaped protrusion 110, the T-shaped slide groove 111, and the T-shaped slider 120, the U-shaped mounting plate 310 can slide on the T-shaped slide groove 111 to adjust the installation position of the lighting lamp 400, thereby increasing the practicality of this application. When the lighting lamp 400 is moved to a suitable position, the U-shaped mounting plate 310 is fixed by the elastic key 130 cooperating with the corresponding adjustment through hole 112 to fix the installation position of the lighting lamp 400. The arc-shaped protrusion 110 is also provided with a disassembly groove 113, which communicates with the T-shaped slide groove 111. By providing the disassembly groove 113, it is convenient to disassemble the T-shaped slider 120, the angle adjustment device, and the lighting lamp 400 as a whole. It should be noted that the T-shaped slider 120 should protrude from the T-shaped slide groove 111 by a certain distance so that the U-shaped mounting plate 310 and the arc-shaped protrusion 110 have a certain distance. This distance is such that it does not hinder the U-shaped mounting plate 310 from sliding with the T-shaped slider 120.

[0036] In some preferred embodiments, the helmet body 100 is provided with reinforcing ribs 140. There are two reinforcing ribs 140, and both reinforcing ribs 140 are connected to the arc-shaped protrusion 110 to form a "V"-shaped reinforcing rib structure, thereby improving the structural strength of the helmet body 100.

[0037] In some preferred embodiments, the helmet body 100 is provided with a plurality of heat dissipation holes 150. The plurality of heat dissipation holes 150 are distributed circumferentially along the helmet body 100 and their axial direction is on the horizontal plane, so as to prevent fine particles or dust from the top of the worker's head from entering the helmet through the heat dissipation holes 150 when the worker wears the helmet.

[0038] In some preferred embodiments, the helmet body 100 is provided with reflective strips 160, wherein the reflective strips 160 improve the visibility of the helmet and the worker wearing the helmet in low-light environments, thereby increasing safety.

[0039] In summary, the safety helmet with adjustable lighting angle provided by this utility model allows for easy adjustment of the lighting angle. When the illumination angle needs to be changed, the operator only needs to use two fingers to press the two rotating inner rods against the rotating sleeve to release the return spring, causing the regular polygonal fixing block and the polygonal stepped groove to separate. Once the illumination angle is adjusted to the appropriate angle, the two fingers are released, and the rotating inner rods return to their original position under the action of the return spring. The regular polygonal fixing block then re-embeds into the polygonal stepped groove, thus fixing the illumination angle. This adjustment method is convenient and quick, solving the technical problems of existing technologies where adjusting the lighting angle requires simultaneous operation of two hands, resulting in complex procedures, inconvenient angle adjustment, and low efficiency.
