Structure for rapid adjustment of inclination of lens

Abstract

The invention discloses a structure for rapid adjustment of the inclination of a lens. The structure comprises a lens holder, a lens assembly is arranged in the lens holder, an end part of the lens holder is connected with a lens cover, the lens cover is provided with a lens, an adjustment mechanism capable of adjusting the distance between the lens cover and the lens holder and the inclination ofthe lens is arranged between the lens cover and the lens holder, the adjustment mechanism comprises a through hole arranged in the circumferential direction of the lens cover, the adjustment mechanism also comprises a threaded hole arranged on the lens holder and corresponding to the through hole, the lens cover is connected with the threaded hole on the lens holder through an adjustment screw arranged in the through hole in a penetrating manner, and a compression spring capable of being arranged on the adjustment screw in a sleeved manner is arranged in the threaded hole. According to the structure, through cooperation of the lens cover, the compression spring, the adjustment screw and the lens holder, the inclination of the lens can be rapidly adjusted by employing and adjusting the counterforce of the compression spring.

Description

【Technical field】 [0001] The invention relates to a structure for quickly adjusting the inclination of a lens. 【Background technique】 [0002] With the rapid development of high technology, security optical zoom lens has been widely used. In order to meet the needs of the market, more and more lenses need to use high-resolution large chips, and zoom lenses must also be used in different fields and environments, making lens design more and more difficult, and the technical requirements of each group are getting higher and higher. The higher the level, the higher the requirements for product molding and process manufacturing. Under the premise of existing manufacturing technology, it is difficult to achieve the initial requirements of optical design, and it is even more difficult to achieve the expected production yield, so that it cannot meet high-speed The increased market demand will eventually make it difficult to maintain the industry leader. [0003] The present invent...
