Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a head-worn protective device for construction engineering. Background Art

[0002] A helmet is a protective gear used to protect the head. It is an indispensable tool for people in transportation, construction sites and certain occasions. It is mostly made of rigid and tough materials for the outer shell, and flexible cushioning materials for the interior to resist the damage to the head caused by striking objects. On construction sites, workers are required to wear safety helmets to ensure their safety.

[0003] The front end of existing construction site safety helmets is usually designed to be flat and without a brim. This is to enable workers to obtain the best field of vision during construction. However, under some special working conditions, such as construction that requires shielding from direct sunlight, the lack of a brim may cause damage to the workers' eyes. Based on this, we propose an improved construction engineering head protection device. Utility Model Content

[0013] The beneficial effects of the utility model are as follows:

[0014] By arranging the mounting block, sleeve block, clamp block, clamp slot, and mounting slot structure, the brim of the hat can be sleeved in the mounting slot through the mounting block, and the mounting block is fixed by sleeved in the clamp slot to achieve quick installation with the safety helmet. At the same time, the clamp block can be pulled out of the clamp slot by the guide rod to disassemble the mounting block, so that the brim of the hat can be quickly removed from the safety helmet, so that the safety helmet can block the sunlight through the brim of the safety helmet when working in direct sunlight to avoid the sunlight affecting the eyes of the workers. In a general working environment, the brim of the hat can be disassembled to avoid the problem of blocking the field of vision.

[0015] By arranging a motor on the brim of the hat to drive the fan blades to rotate to supply air, it can assist workers in blowing air to dissipate heat when working in hot weather, thereby preventing workers from suffering from heatstroke due to excessively high temperatures, which is very practical.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a construction engineering head protection device includes a safety helmet 1 and a brim 2, a sleeve block 8 is fixedly connected to the middle part of the front end of the safety helmet 1, a mounting groove 13 is provided at the front end of the sleeve block 8, a mounting plate 14 is fixedly connected to the middle part of the upper end of the brim 2, a mounting block 15 is fixedly connected to one side of the mounting plate 14, the mounting block 15 is slidably sleeved in the mounting groove 13, a guide plate 9 is fixedly connected to one side of the sleeve block 8, a guide rod 10 is slidably sleeved on the guide plate 9, a clamping block 11 is fixedly connected to one end of the guide rod 10, a clamping groove 16 is provided on one side of the mounting block 15, and the clamping block 11 is slidably sleeved in the clamping groove 16.

[0023] In this embodiment, a mounting ring 3 is fixedly sleeved on the brim 2, a fixing plate 4 is fixedly connected inside the mounting ring 3, a motor 5 is fixedly provided on the upper end of the fixing plate 4, an output end of the motor 5 passes through the fixing plate 4 and is fixedly sleeved with a fan blade 6, and the fan blade 6 is driven by the motor 5 to rotate to supply air.

[0024] In this embodiment, an air outlet is provided at the lower end of the mounting ring 3, and the air outlet is arranged in an oblique downward structure, so that the air flow can blow obliquely downward toward the worker's face.

[0025] In this embodiment, a filter screen 19 is fixedly sleeved near the upper end of the mounting ring 3 to filter debris to prevent it from blowing toward the worker's face and causing visual impact or facial scratches. A battery box 7 is fixedly set on one side of the upper end of the brim 2, and a power supply battery is provided in the battery box 7 to power the motor 5.

[0026] In this embodiment, a spring 12 is fixedly connected between the block 11 and the guide plate 9. The spring 12 is movably sleeved on the outer end of the guide rod 10. The spring 12 is used to reset the block 11 so that the block 11 can always be stuck in the slot 16 during the installation of the mounting block 15 to prevent the mounting block 15 from detaching.

[0027] In this embodiment, the mounting block 15 is made of an inclined structure at one end close to the sleeve block 8, which automatically lifts up the clamping block 11 during installation. The guide rod 10 is fixedly connected to the end away from the clamping block 11 with a pull cap, and the pull cap can be used to conveniently pull the guide rod 10 to move, thereby pulling the clamping block 11 to move.

[0028] In this embodiment, positioning sleeves 18 are fixedly connected to the front and rear outer walls of the safety helmet 1, and positioning pins 17 are fixedly connected to the upper end of the brim 2 near the front and rear positions. The two positioning pins 17 are respectively slidably connected with the two positioning sleeves 18. The positioning pins 17 are connected with the positioning sleeves 18 to assist in loading the weight of the brim 2 and guiding it.

[0029] It should be noted that the utility model is a head-worn protective device for construction projects. When in use, when it is necessary to wear the brim 2 to work, the positioning pin 17 is aligned with the positioning sleeve 18 and inserted. At this time, the mounting block 15 is pushed into the mounting groove 13, and the clamping block 11 is squeezed by the inclined surface of the mounting block 15 to rise and compress the spring 12. When the clamping groove 16 moves to the clamping block 11, under the reaction force of the spring 12, the clamping block 11 is re-inserted into the clamping groove 16 to fix the mounting block 15, thereby completing the installation of the brim 2. When the weather is hot, the motor 5 can be started to drive the fan blades 6 to rotate, attracting air flow to blow to the worker's face for heat dissipation, making the worker feel more comfortable and cool.
