Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a photocuring lamp-house external use lens hood.
Background
Photocuring refers to the process of curing a monomer, oligomer or polymer matrix under light induction, and is generally used in film forming processes. The technology has the characteristics of high efficiency, wide adaptability, economy, energy conservation and environmental protection. Photocuring of unsaturated polyester resin; the activation energy generated by the ultraviolet light with the highest energy in the spectrum can break the C-C bond of the unsaturated polyester resin to generate free radicals so as to cure the resin. When the photosensitizer is added into the unsaturated polyester resin, the photosensitizer is initiated by using ultraviolet rays or visible light as energy, so that the resin can quickly generate a crosslinking reaction.
In the process of tooth repairing treatment, resin for filling decayed teeth needs to be solidified through photocuring effect so as to repair teeth, but light emitted by a photocuring lamp is harmful to eyes of people, when a dentist holds the photocuring lamp to irradiate the inside of a mouth of a patient, the curing condition of the resin inside the teeth needs to be checked at any time, so that inevitable eyes can be irradiated by the photocuring lamp, and a device capable of shielding the light of the photocuring lamp outside the mouth needs to be designed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a photocuring lamp-house external use lens hood to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a light-curable external light shield for a light fixture, comprising: photocuring lamp body, lens hood and protective sheath, photocuring lamp body comprises handheld portion and illumination portion, illumination portion includes connecting rod and lamp holder, the lens hood comprises solid fixed ring, first movable rod and second movable rod, gu fixed ring is one and has the open-ended ring, and gu be equipped with one spout on the fixed ring lateral wall, and the tip of first movable rod and second movable rod be equipped with spout complex slider, first movable rod and second movable rod pass through the slider with gu fixed ring sliding connection to be equipped with the cover body between first movable rod and the second movable rod, first movable rod and second movable rod all have magnetism simultaneously, and magnetism is inhaled mutually, the protective sheath cover is in the outside of lamp holder and connecting rod to the opening part of protective sheath is fixed by the stationary ring.
As a further aspect of the present invention: the fixing ring is made of deformable metal materials.
As a further aspect of the present invention: the cover body is in a foldable corrugated shape.
