Description

Technical Field

[0001] This utility model relates to the field of construction protective gear technology, and in particular to a construction protective gear that is easy to wear. Background Technology

[0002] During construction, workers often face various potential dangers, such as falls from heights, injuries from falling heavy objects, and machinery injuries. Therefore, using protective gear to improve safety is one of the most important measures on construction sites. However, due to the different needs of different working environments and job types, existing protective gear often only provides protection in one aspect and cannot meet safety requirements in multiple aspects simultaneously.

[0003] Application number CN202022266276.8 discloses a dustproof protective gear for construction work, including a safety helmet and two chin straps installed on the lower side of the helmet. Fixed rods are fixedly connected to both sides of the safety helmet. A frame is provided below the helmet, and goggles are installed inside the frame. A groove is provided on the inner side of the frame, and the goggles are detachably connected to the frame. Mounting brackets are fixedly connected to both sides of the frame, and a dustproof face shield is provided below the frame. A sleeve is provided on the dustproof face shield, and a Velcro fastener is fixedly connected to the end of the sleeve away from the face shield. The Velcro fastener is adhered to the face shield. This utility model employs a sliding structure for easy removal and replacement of the goggles, a rotating structure to avoid the frame obstructing vision, and a wrap-around structure to improve dust protection in different situations.

[0004] The device uses buckles and blocks to secure the chin strap, which is not easy to adjust to different face sizes. This results in a loose fit between the helmet and the head, providing inadequate protection in dangerous situations and reducing safety. The rotating structure avoids the frame from affecting vision, but the frame still needs to be constantly rotated to maintain clear vision during different tasks, which is inconvenient and reduces work efficiency. Utility Model Content

[0005] To address the problems of the aforementioned devices being inconvenient to adjust to different face sizes, providing inadequate protection in dangerous situations, reducing safety, and requiring constant rotation of the frame during use, this utility model provides a wearable protective gear for construction.

[0006] This utility model is achieved using the following technical solution: a construction protective gear that is easy to wear, including a helmet, with an edge support plate fixedly connected to the outside of the helmet, a helmet strap fixedly connected to the bottom of the edge support plate, and a pad fixedly connected to the outside of the helmet strap; it also includes a wearing mechanism, which includes a rotating frame fixedly connected to the top of the edge support plate, a rotating column rotatably connected to the inner wall of the back of the rotating frame, a worm gear fixedly connected to the outside of the rotating column, a winding column fixedly connected to the outside of the worm gear, a worm rotatably connected to the inner wall of the right side of the rotating frame, a rotating disk fixedly connected to the end of the worm away from the rotating frame, and a lighting lamp fixedly connected to the top of the rotating frame.

[0007] The above technical solution allows the worm gear to rotate by twisting the rotating disc, which in turn meshes with the worm gear to rotate the winding column. Simultaneously, the helmet strap is wound around the outside of the winding column, allowing adjustment of the length of the helmet strap.

[0008] As a further improvement to the above solution, the end of the worm gear away from the rotating frame passes through the rotating frame, the helmet fixing strap is fixedly connected to the outside of the winding column, the rotating column is rotatably connected between the inner wall of the back and the inner wall of the front of the rotating frame, and the worm wheel meshes with the worm gear.

[0009] As a further improvement to the above solution, a through groove is provided at the bottom of the rotating frame, and the portion of the helmet fixing strap near the rotating frame is slidably connected to the inside of the support plate.

[0010] As a further improvement to the above solution, a protective mechanism is fixedly connected to the top of the edge support plate. The protective mechanism includes a support block fixedly connected to the top of the edge support plate, a rotating shaft fixedly connected to the right side of the support block, a support frame rotatably connected to the outside of the rotating shaft, a protective cover fixedly connected to the left side of the support frame, a lens adjustment block fixedly connected to the front of the protective cover, a sliding column fixedly connected to the inside of the lens adjustment block, a protective lens slidably connected to the outside of the sliding column, a first spring fixedly connected to the bottom of the protective lens, and a locking block rotatably connected to the bottom of the protective lens.

[0011] With the above technical solution, the protective lens can be pressed down and moved. When it reaches the bottom, the locking block is rotated to lock into the slot set in the lens adjustment block. At this time, the first spring is under pressure. When the locking block is rotated to disengage from the slot, the protective lens bounces back to the initial position under the action of the first spring.

[0012] As a further improvement to the above solution, the first spring is fixedly connected between the lens adjustment block and the protective lens, the sliding column is set inside the first spring, the lens adjustment block has a sliding groove inside, there are two support frames, which are distributed on the top of the edge support plate, and a slot block is provided on the right side of the lens adjustment block.

[0013] As a further improvement to the above solution, a grooved rotating column is fixedly connected to the left side of the support frame, a limiting support frame is rotatably connected to the outside of the grooved rotating column, a second spring is fixedly connected to the left side of the limiting support frame, a limiting column is rotatably connected to the left side of the limiting support frame, a limiting sliding block is slidably connected to the outside of the limiting column, and a limiting locking block is fixedly connected to the right side of the limiting sliding block.

[0014] With the above technical solution, the limiting sliding block can be pulled to drive the limiting card block to disengage from the grooved rotating column and rotate the limiting support frame. After the rotation is completed, the limiting sliding block can be released so that the limiting card block can be inserted into the grooved rotating column to complete the limiting.

[0015] As a further improvement to the above solution, a limiting hole is provided on the left side of the grooved rotating column, and the limiting hole on the left side of the grooved rotating column matches the limiting block. The second spring is fixedly connected between the limiting sliding block and the limiting support frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention allows the rotating disc to drive the worm gear to rotate, causing the worm wheel to mesh with the worm gear and drive the winding column to rotate. This adjusts the position of the pad, making the pad fit against the chin. At the same time, it causes the helmet strap to wrap around the outside of the winding column. The length of the helmet strap can be adjusted to ensure a tighter fit between the helmet and the head for people of different head sizes, thus improving safety.

[0018] This invention allows the protective lens to be adjusted downwards by pressing it. At this time, the first spring is under pressure. When it reaches the bottom, the locking block is rotated to lock into the slot of the lens adjustment block. The locking block is then fixed by the rebound. When the locking block is released from the slot, the protective lens can be pressed and the locking block can be rotated to release it from the slot. At the same time, the protective lens rebounds back to its initial position under the action of the first spring. This allows for quick adjustment of the protective lens when facing different working environments, ensuring clear vision and improving work efficiency. Attached Figure Description

[0035] The implementation principle of a wearable protective gear for construction in this application embodiment is as follows: When in use, the helmet 1 is first worn on the head. The position of the pad 13 is adjusted so that it fits snugly against the chin. The rotating disk 206 is then rotated, causing the worm gear 205 to rotate, meshing with the worm wheel 203, which in turn rotates the rotating column 202 and the winding column 204. The helmet strap 12 wraps around the winding column 204 and continuously shortens. Once shortened to the appropriate position, the rotating disk 206 is stopped, completing the wearing process. If the construction environment is dark, the lighting lamp 207 can be turned on for illumination. During use, the protective cover 304 can be moved by pulling the limiting sliding block 3014 along the limiting column 3013, causing the limiting latch 3015 to disengage from the limiting groove of the grooved rotating column 3010, thus rotating the protective cover 304. After rotating to the appropriate position, the limiting sliding block 3014 can be released, causing it to spring back under the action of the second spring 3012. The limiting block 3015 is inserted into the limiting groove of the grooved rotating column 3010 to limit the movement of the protective cover 304. Simultaneously, the protective lens 307 blocks sparks and strong light during operation to protect the eyes. When observation of the processed part is needed, the protective lens 307 can be pressed, causing it to move downwards along the sliding column 306. After moving to the appropriate position, the locking block 309 is rotated so that it aligns with the locking groove on the outside of the protective cover 304. At this point, the locking block is released. Under the action of the first spring 308, the protective lens 307 drives the locking block 309 to move upward, so that the locking block 309 contacts the locking slot block, limiting the protective lens 307 and making the vision clearer. After observation, the protective lens 307 can be pressed to drive the locking block 309 out of the locking slot block position, and the locking block 309 can be rotated to make the protective lens 307 return to the initial position under the rebound of the first spring 308, avoiding the need to rotate the protective cover 304 multiple times and improving work efficiency.
