Description

The pneumatic control device of industrial glasses

This utility model relates generally to a kind of pneumatic control device of industrial glasses, and it is used for getting rid of during operation heat that is sent by human body and the fog that is produced at industrial glasses by this heat.Particularly, this utility model relates to a kind of like this pneumatic control device of industrial glasses, and it can pass through to form air inlet/steam vent at the left and right sides of the upper and lower surface of industrial glasses, thereby optionally controls entering and discharging of air according to working condition.

Industrial glasses are widely used in protecting operator's eyes to avoid the injury of the dust and the foreign body of multiple harm ray, disperse, and these materials are to handle grinding, cutting, pulverizing or air slaking material, pesticide or chemicals or producing man-hour in coating, welding, Laser Processing, grinding or similar adding.

The heat that produces in these technologies can cause producing fog at the inner surface of lens, and the fog that is produced can hinder operator's sight line, thereby causes significant inconvenience at work.Therefore, attempted to adopt multiple mode to get rid of heat.

So far disclosed conventional air control device is a fixed pattern, and wherein the upper and lower surface at industrial glasses is provided with the passage with appropriate size, to guarantee air circulation.But traditional pneumatic control device has such shortcoming, and promptly it can not arbitrarily control entering and discharging of air according to the variation of working condition.Its another fatal shortcoming is to stop the microgranule of aerial various dusts of disperse during operation or chemicals to suck the inboard of industrial glasses.

Therefore, the purpose of this utility model is to provide a kind of pneumatic control device of industrial glasses, it can be by arbitrarily controlling the opening angle of air inlet/steam vent, control entering and discharging of air with variation, thereby can under any working condition, make the wearer have comfortable sensation according to working condition.

For achieving the above object, this utility model provides a kind of pneumatic control device of industrial glasses, and it comprises: a framework, and it has a fastening part that is positioned at the lens on its front surface and is positioned at the left and right sides of its upper surface and lower surface; Be arranged on the air inlet on the fastening part that is formed on the lower surface, each air inlet all can be formed at the switching angle that a lid is arbitrarily controlled in engagement between the elongator on the side plate by being formed on gear and on the guide plate; And being arranged on steam vent on the fastening part that is formed on the upper surface, each steam vent all can be formed on gear and on the guide plate by one and be formed at the switching angle that a lid is arbitrarily controlled in engagement between the elongator on the side plate.

Each air inlet includes: a retainer ring, and this retainer ring has a groove in its periphery; One guide plate, this guide plate have a gear and are distributed to the retainer ring both sides in an one side; A lid integrally formed, described side plate with side plate have one with the elongator that extends internally of described gears engaged, all these parts all are integrally molded on the rear side of retainer ring.

Each steam vent that is formed on the upper surface includes: a retainer ring that is positioned at its periphery; One guide plate, this guide plate has a gear and is distributed to the retainer ring both sides at the one inner surface; One with the integrally formed lid of side plate, described side plate have one with the elongator that extends internally of described gears engaged, all these parts all are integrally molded on the rear side of retainer ring.

Pneumatic control device of the present utility model can be controlled the opening angle of described lid according to the change of working condition, can arbitrarily control entering and discharging of air thus, thereby can prevent to be trapped in industrial glasses inboard, and prevent from industrial glasses, to produce fog by described heat by the heat that human body sends.

Below in conjunction with accompanying drawing, and will more be expressly understood above-mentioned and other purpose of the present utility model, characteristics and advantage by following description, wherein:
