Description

Laser protective mask

Technical Field

The utility model belongs to laser protection field especially relates to a laser protective face mask.

Background

Laser radiation can cause serious damage to the human eye and skin. The human eyes have different transmission and absorption of laser with different wavelengths, and the parts of the human eyes damaged by the laser with different wavelengths are also different. The eye injury caused by laser irradiation is mainly photokeratitis (also called electric ophthalmia or snow blindness) caused by ultraviolet rays, burn, coagulation, perforation, hemorrhage and burst of retina caused by visible light, and clouding of crystalline lens, corneal coagulation and the like caused by infrared light. Skin damage caused by laser radiation is mainly pigmentation, erythema, blisters and the like.

The laser protective mask can protect eyes and skin of an operator in laser operation.

However, the angle of the mask cannot be adjusted by the existing laser protective mask, and when a user does not need to use the mask in the laser operation process, the user needs to take off the mask from the head and then put on the mask, so that inconvenience is caused by taking off and wearing the mask for many times; meanwhile, the existing protective mask is not only complicated in wearing steps, but also not easy to fix.

SUMMERY OF THE UTILITY MODEL

The utility model provides a laser protective face mask aims at solving current face mask and need take problem of wearing and loaded down with trivial details problem of step when dressing many times on the way in laser operation.

The utility model discloses a realize like this, a laser protective mask, a serial communication port, include:

the left end of the rotatable bracket is fixedly connected with the mask, and the right end of the rotatable bracket is hinged with the left end of the fixed frame;

the head clamp comprises a head hoop, wherein the outer side of the right end of the head hoop is fixedly connected with one end, far away from the rotatable support, of the fixing frame, a small groove is formed in the fixing frame and the right end of the head hoop, a group of spring hinge shafts penetrate through the small groove from top to bottom, the spring hinge shafts are connected with a head clamp through spring hinges, and the head clamp can rotate around the spring hinge shafts in the small groove.

Further, the front and rear surfaces of the mask are uniformly coated with a mirror oil.

Furthermore, an anti-slip layer is fixedly connected to the inner side of the fixing frame.

Furthermore, the inner side of the anti-skid layer is provided with anti-skid lines.

Further, the four sides of the face mask are wrapped with hems.

Still further, the material of the face mask is polycarbonate.

Compared with the prior art, the utility model discloses a during beneficial effect: the rotatable bracket can rotate on the fixed frame, so that the problems that the angle of the mask cannot be adjusted when the existing mask is used and the mask needs to be worn for many times during laser operation are solved; meanwhile, the head clamp can rotate through the spring hinge, so that the head of a user can be conveniently and firmly buckled, and the wearing steps of the existing mask are simplified.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present embodiment, with reference to fig. 1 to 3, a laser protective mask is characterized by comprising:

the left end of the rotatable bracket 3 is fixedly connected with the face mask 2, and the right end of the rotatable bracket 3 is hinged with the left end of the fixed frame 4;

the head clamp comprises a head hoop 5, the outer side of the right end of the head hoop 5 is fixedly connected with one end, far away from the rotatable support 3, of the fixing frame 4, a small groove is formed in the fixing frame 4 and the right end of the head hoop 5, a group of spring hinge shafts 9 penetrate through the small groove from top to bottom, the spring hinge shafts 9 are connected with a head clamp 6 through spring hinges, and the head clamp 6 can rotate around the spring hinge shafts 9 in the small groove.

Mirror surface oil is evenly coated on the front surface and the back surface of the face mask 2, so that fingerprints can be prevented from being left on the surface of the face mask 2 by a user. The inner side of the fixing frame 4 is fixedly connected with an anti-slip layer 7, the anti-slip layer 7 can prevent the hair of a user from being clamped by the spring hinge when the head clamp 6 moves, and can play a certain buffering role when the head clamp is retracted. The anti-skidding layer inboard is equipped with anti-skidding line 8, can guarantee that the firm card of head clamp is in user's head. Four sides of the face mask 2 are wrapped with wrapping edges 1, and the wrapping edges 1 can prevent a user or an instrument from being cut or scratched by the periphery of the face mask 2. The mask 2 is made of polycarbonate, so that the laser can be prevented from directly irradiating the skin and eyes.

When using the laser protective mask, a user rotates the head clip 6 around the spring hinge shaft 9 toward both sides while putting the head band 5 on the forehead of the user, and then rotates the head clip 6 around the spring hinge shaft 9. When a user does not need to use the face mask 2 for protection, the bottom of the face mask 2 can be lifted, the rotatable bracket 3 fixedly connected with the face mask 2 rotates upwards, and the face mask 2 rotates upwards along with the rotatable bracket to rotate to the angle desired by the user.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
