Description
Technical field
The relevant a kind of face shield ear cover structure of this utility model, refer in particular to the preceding frame that a kind of energy will be connected with face shield and do to dismantle to do adjustment of multisection type wide-angle and front and back displacement, and the button portion disassembly and assembly of earmuff and rotary fixing frame easily and the modularity safety eyewear ear cover structure of difficult drop-off and suitable big or small various head dummys.
Background technology
Face shield the time can be avoided foreign body for work and directly injure the usefulness of eyes as the protection eyes, current no matter factory, outdoor gardening, laboratory etc. are indispensable necessary, and its structure of face shield of existing articles for use is fixed, be fixed in head by an elastic strands, because its structural design is bad, except can't secure in head, its top is without any support, so face shield is easy to glide because of weight relationships, this face shield can't start and various angle adjustment again, more causes the inconvenience in the use; Though someone invents to constructing and goes up to preventing the injury of noise to ear, and be provided with earmuff in face shield, yet the earmuff of existing articles for use mainly is fixed on the headgear of fixed dimension, utilization has U-shaped shape trepanning and is located at the buckling plate of its trepanning one side, the fastening that bar wears U-shaped shape trepanning and buckling plate of striding by earmuff fixes, because it has the U-shaped shape trepanning of the long arm of force existing articles for use, therefore can't bear earmuff and stride the weight of bar, earmuff comes off in U-shaped shape trepanning easily, the bar of striding of earmuff is assembled and must be worn to afterbody by head at fastening again, and the side buckling plate is made accurate clip seal, quite time-consuming taking a lot of work in operation and fastening and the dismounting, it can't can't be made the face shield that is provided with earmuff quick dismounting and change at all and do front and back displacement and adjustment to present articles for use again, often cause and user inapplicable in different places, fixed headgear can't be fit to outside the user use of all size capitiform, be located at the face shield on the headgear if will do fine setting adjustment, then must decompose the beginning fully and can make to finely tune the adjustment angle putting in order the group part, can't satisfy the needs of user, these all disappearances that manifest, usually cause work can't carry out smoothly and dangerous the generation, this is to be dealer and consumer's utmost point desire breakthrough part, it serves as to consider to create that the inventor puts with this, become a preceding frame that can will be connected to dismantle eventually and can do multisection type wide-angle directly adjustment and front and back displacement with face shield, and the button portion disassembly and assembly of earmuff and rotary fixing frame are easy and difficult drop-off, effectively promote the modularity safety eyewear ear cover structure of its ease of use and suitable various head dummys.
Summary of the invention
For solving above-mentioned prior art weak point, this utility model main purpose is providing a kind of modularity safety eyewear ear cover structure, its face shield is convenient for changing and need not dismantles adjustment and the front and back displacement that promptly can make the multisection type wide-angle and adjusts with being fit to various head dummy sizes, in the hope of overcoming difficulty of the prior art.
Secondary objective of the present utility model is to provide a kind of modularity safety eyewear ear cover structure, the easy and difficult drop-off of the button portion disassembly and assembly of its earmuff and rotary fixing frame.
Another purpose of the present utility model is to provide a kind of modularity safety eyewear ear cover structure, and the button portion selectivity of its rotary fixing frame is difference in functionality is done the top in conjunction with the pars contractilis that is provided with earmuff or adjusts up and down support.
