[0022] 1. In the utility model, when it is necessary to remove and clean the ventilation block, the pin rods are pulled to both sides through the handles respectively, so that the engagement state with the ventilation block is released and the pin rods retract into the installation shell. At the same time, the limiting block is driven to compress the spring, and then the ventilation block can be removed. When the limiting block moves to both sides, the blocking plate will automatically fall down under the influence of gravity to block the limiting block, so that the user can release the handle for convenient operation. When installing the ventilation block, only need to pull up the blocking plate through the sliding plate. Under the action of the resilience of the spring, the limiting block moves relatively to drive the pin rod to engage and fix with the ventilation block again, realizing the effect of enhancing the air permeability of the helmet through the ventilation mechanism. And through the installation mechanism, the ventilation block is convenient to disassemble and clean, improving the wearing comfort and the practicability of the device.

[0023] 2. In the present utility model, when the protective goggles are installed on the main body, the angle of the protective goggles can be adjusted by rotating the toothed ring. When the protective goggles do not need to be installed, the buckle is pulled backward to make the snap ring contract into the inside of the reinforcement ring to release its engagement with the protective goggles, and then the protective goggles can be removed. When installing, only need to push the buckle forward to make the snap ring engage into the inside of the protective goggles, achieving the effect of quickly installing and disassembling the protective goggles through the engaging mechanism. When the operator is performing electric welding or other operations that require eye protection, the protective goggles can be quickly installed for operation without replacing a special protective helmet, reducing the operation cost and improving the practicability of the device.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a safety helmet convenient to wear, including a main body 1. A protective mirror 2 is rotatably connected to the front end of the main body 1. A ventilation mechanism is arranged on the top of the main body 1, and the ventilation mechanism is used for internal ventilation when the main body 1 is worn. A clamping mechanism is arranged on the outside of the main body 1, and the clamping mechanism is used for quickly installing or removing the protective mirror 2. The ventilation mechanism includes a ventilation block 3. The ventilation block 3 is slidably connected to the top of the main body 1. An installation mechanism is arranged outside the ventilation block 3, and the installation mechanism is used for removing the ventilation block 3 for cleaning. The installation mechanism includes two installation shells 4. The installation shells 4 play a role in fixing the internal structure. The bottoms of the two installation shells 4 are fixedly connected to the top of the main body 1. Springs 5 are fixedly connected inside the two installation shells 4. The springs 5 play a role in providing elastic force to push the limit blocks 6. Limit blocks 6 are fixedly connected to the opposite sides of the two springs 5. The limit blocks 6 play a role in preventing the springs 5 from falling off. Pin rods 7 are fixedly connected inside the two limit blocks 6. The pin rods 7 play a role in clamping and fixing. Both pin rods 7 are engaged with the ventilation block 3. A fixed box 8 is fixedly connected to the top of the installation shell 4. The fixed box 8 plays a role in fixing the internal structure. A slide plate 9 is slidably connected inside the fixed box 8. A blocking plate 10 is fixedly connected to the bottom of the slide plate 9. The blocking plate 10 plays a role in blocking the limit block 6. The bottom of the blocking plate 10 is engaged with the top of the limit block 6. The limit block 6 is slidably connected inside the installation shell 4. The pin rod 7 penetrates through both ends of the installation shell 4. Handles 11 are fixedly connected to the opposite sides of the two pin rods 7.

[0032] Referring to Figure 1 , Figure 4 , the clamping mechanism includes two reinforcement rings 12. The reinforcement rings 12 play a role in connecting the mounting seats 14. Both reinforcement rings 12 are fixedly connected to the outside of the main body 1. Tooth rings 13 are fixedly connected to the front ends of the two reinforcement rings 12. The tooth rings 13 play a role in rotating the protective mirror 2. Clamping rings 16 are slidably connected to the opposite sides of the two reinforcement rings 12. The clamping rings 16 play a role in clamping and fixing. Mounting seats 14 are fixedly connected to the opposite sides of the two reinforcement rings 12.

The buckles 15 play a role in connecting the clamping rings 16. The two buckles 15 are respectively abutted against the two clamping rings 16.

[0033] Working principle: When it is necessary to remove and clean the ventilation block 3, the pin rods 7 are respectively pulled to both sides through the handles 11 to release their engagement with the ventilation block 3 and retract into the installation shell 4. At the same time, the limit blocks 6 are driven to compress the springs 5, and then the ventilation block 3 can be removed. When the limit blocks 6 move to both sides, the blocking plate 10 will automatically fall under the influence of gravity to block the limit blocks 6, enabling the user to release the handles 11 for convenient operation. When installing the ventilation block 3, only need to pull up the blocking plate 10 through the slide plate 9. Under the action of the restoring force of the spring 5, the limit blocks 6 move relatively to drive the pin rods 7 to engage and fix with the ventilation block 3 again.

[0034] When the protective goggles 2 are installed on the main body 1, the angle of the protective goggles 2 can be adjusted by rotating the protective goggles 2 through the gear ring 13. When the protective goggles 2 do not need to be installed, the buckle 15 is pulled backward to make the snap ring 16 contract into the inside of the reinforcement ring 12 to release its engagement with the protective goggles 2, and then the protective goggles 2 can be removed. During installation, just push the buckle 15 forward to make the snap ring 16 engage into the inside of the protective goggles 2.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
