Background technology

In the time carrying out power construction, conventionally need safe wearing face shield to protect face.But, in the time carrying out power construction, the wearing also than indispensable of safety cap.Existing safety eyewear is all the heads wearer by static line or bar colligation, and the in the situation that of safe wearing cap, wearing of safety eyewear will be very inconvenient, and user has to safety eyewear colligation on safety cap.Due to safety cap smooth surface, make safety eyewear be difficult to keep firm, easily drop, can not well play protection effect.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can be firm be fixed on the safety eyewear on safety cap.

The purpose of this utility model is achieved through the following technical solutions:

Safety eyewear, comprises framework, mask body, sucker and sealing plectrum; Mask body is fixed on framework; The middle position of the outer surface of cupular part of framework is provided with plane, offers chute in plane, and sealing plectrum slides and is arranged in chute; Sucker is connected with the middle position of frame roof inner surface; Also comprise tubule, tubule runs through plane, and one end of tubule is positioned at the bottom of chute, and the other end of tubule is communicated with sucker, and the position of tubule is configured to block by the sealed plectrum of hydrodynamic reciprocating sealing plectrum.

The utility model, in the time wearing, is pressed on sucker on safety cap, and the air between sucker and safety cap is discharged by tubule, and then hydrodynamic reciprocating sealing plectrum makes to seal plectrum and shelters from tubule, prevents that air from entering.So, the utility model can firm being adsorbed on safety cap.The utility model is worn conveniently, has utilized the ganoid characteristic of safety cap, has realized firm fixing.

Further, the bottom surface of described sealing plectrum is enclosed with flexible rubber.

The bottom surface parcel flexible rubber of sealing plectrum, can make to seal plectrum and better realize the sealing to tubule, prevents that air from entering between sucker and safety cap outer surface by tubule.

Further, on described framework, be provided with multiple joint pins; Also comprise and rotate the rubber plectrum being fixed on joint pin; On described mask body, offer multiple holes corresponding with rubber plectrum, rubber plectrum is pressed on described mask body on described framework through hole.

Traditional mask body and framework are monolithic construction, or between mask body and framework, are non-dismountable connection, if mask body breakage, whole safety eyewear will be scrapped.

In utility model, it between mask body and framework, is detachable connection.Mask body is affixed on framework, and rubber plectrum is through the hole on mask body, and then rotating rubber plectrum can be pressed on mask body on framework.In the utility model, mask body can be easy to be mounted and take off, and in the situation that mask body damages, can change separately mask body, has reduced cost.

Further, described framework comprises that center of top position offers frame body jaggy and rotate the adjustment body that is fixed on indentation, there by rotating shaft, and described plane is positioned at tune on the whole, described sucker with adjust integrated connection.

Under the effect of rotating shaft, frame body can be with respect to adjusting unitary rotation, thus the adjustment that realizes safety eyewear and wear angle.

Further, in described rotating shaft, be enclosed with damping rubber.

Damping rubber can increase the frictional force between rotating shaft and frame body, is adjusting after the angle of safety eyewear, and larger frictional force contributes to maintain the angle of wearing of safety eyewear.

In sum, advantage of the present utility model and beneficial effect are:

1. the utility model is worn conveniently, has utilized the ganoid characteristic of safety cap, can be firm by sucker be fixed on safety cap;

2. the bottom surface parcel flexible rubber of sealing plectrum, can make to seal plectrum and better realize the sealing to tubule, prevents that air from entering between sucker and safety cap outer surface by tubule, improved reliability of the present utility model;

3. the utility model can be changed separately mask body, has reduced cost;

4. the angle of wearing of the present utility model can be adjusted, easy to use, widely applicable;

5. in rotating shaft, be enclosed with damping rubber, contribute to maintain the angle of wearing of safety eyewear.
