Problems solved by technology
[0002] In the prior art, due to the simple structure and single function of the existing construction helmets, there will be a lot of noise during the construction process, and the workers will be in it for a long time, which will cause damage to the ears. The existing construction helmets It is inconvenient to wear, and the heat dissipation effect is poor, so there is an urgent need for a construction safety helmet to solve the above problems

specific Embodiment approach
[0018] Specific implementation method: when in use, the operator wears the cap body 3 on the head, so that the buffer strip 1 fits the head, avoiding that in hot weather, the heat is directly transferred to the head through the cap body 3, which affects the operation At the same time, due to the arrangement of ventilation holes and dust-proof net 2, the heat dissipation effect is improved, and dust is prevented from entering the cap body 3 through the ventilation holes. When the cap body 3 is impacted by external force, the impact force is reduced under the action of the buffer zone 1 , to avoid damage to the head, then hold the elastic band 10 and move to the right, then clamp the fixing ring 11 in the slot on the fixing rod 12, and then fix the cap body 3, when working in a noisy environment, The operator turns the sound-proof cover 9 to the right, and the sound-proof cover 9 drives the sound-absorbing panel and the rubber ring 8 to move to the right. At the same time, the so...

The invention provides a safety helmet for building construction, which comprises a first gear, a mounting block, a second gear, a connecting rod, a rubber ring, a sound insulation cover, an elastic belt, a fixing ring and a fixing rod, wherein the first gear is assembled in the mounting block, the mounting block is welded on the left end of the body of the helmet, and the second gear is assembledin the mounting block, the second gear is meshed with the first gear through a gear, the upper end of the connecting rod is connected with the second gear, the rubber ring is adhered on the right endsurface of the sound insulation cover, the sound insulation cover is connected with the second gear through the connecting rod, the sound insulation cover is arranged at the left end of the helmet body, the left end of the elastic belt is fixed to the left end of the helmet body on the front side of the sound insulation cover, the right end of the elastic belt is connected with the fixing rod through the fixing ring, the right end of the fixing rod is fixed on the right end of the helmet body through screws. The design facilitates wearing, protecting the ears and heat dissipation and avoids dust, the helmet is convenient to use and easy to wear, the ears are conveniently protected, the heat dissipation is facilitated and the dust is avoided, the reliability is high.
Description
technical field [0001] The invention relates to a building construction safety helmet, which belongs to the field of construction safety helmet equipment. Background technique [0002] In the prior art, due to the simple structure and single function of the existing construction helmets, there will be a lot of noise during the construction process, and the workers will be in it for a long time, which will cause damage to the ears. The existing construction helmets It is inconvenient to wear, and the heat dissipation effect is poor, so a kind of building construction safety helmet is badly in need of to solve the above-mentioned problems that occur. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a construction safety helmet to solve the problems raised in the above-mentioned background technology. The present invention is easy to use, easy to wear, easy to protect ears, easy to dissipate heat...
