Mobile phone photographic fixing bracket provided with telescope eyepiece

Abstract

The invention discloses a mobile phone photographic fixing bracket provided with a telescope eyepiece. The mobile phone photographic fixing bracket comprises a sleeve; a plurality of connection sleeves of which the diameters are increased gradually are moulded at a front end of the sleeve; an upper end of a connection sleeve at a most front end of the sleeve is connected with a locking bolt in a screwed manner; a vertical bottom plate is moulded on a sidewall of a rear end of the sleeve; supporting columns are fixed on a side edge of the bottom plate; pressure springs are fixed on the supporting columns through a clamp plate in an insertion and sleeving manner; two ends of the pressure springs are respectively propped against on the clamp plate and limit sleeves; the limit sleeves are fixed on the supporting columns in an insertion and sleeving manner; a baffle block is respectively moulded on an upper end surface and a sidewall of the bottom plate; a slot is formed in each of the baffle blocks; a supporting plate is moulded on a sidewall, far away from the side with the baffle blocks, of a lower end of the clamp plate; a first insertion hole is formed in the supporting plate; anda second insertion hole is formed in a rear end surface, opposite to a center of the sleeve, of the clamp plate. According to the mobile phone photographic fixing bracket, the structure is simple, andthe installation and the connection with mobile phones with multiple specifications and sizes are implemented conveniently; and meanwhile, the installation and the connection with eyepieces with multiple specifications are also conveniently implemented.

Description

Technical field: [0001] The invention relates to the technical field of optical instrument accessories, and more specifically relates to a fixed bracket for taking pictures of a mobile phone equipped with a telescope eyepiece. Background technique: [0002] Visual optical instruments are generally composed of objective lenses and eyepieces, such as our telescopes, microscopes, etc. The eyepieces are used to further clearly and magnify the image magnified by the objective lens to the human eye. Photography behind the eyepiece is to replace the human eye with a camera or mobile phone. The lens of the camera is equivalent to the human lens, and the sensor of the camera is equivalent to the human retina. When the camera is placed behind an optical instrument equipped with an objective lens and an eyepiece, and the optical axis of the camera is coaxial with the optical axis of the optical instrument, and adjusted to an appropriate distance, the camera can capture the image seen b...

AI Technical Summary

Problems solved by technology

When the camera is placed behind an optical instrument equipped with an objective lens and an eyepiece, and the optical axis of the camera is coaxial with the optical axis of the optical instrument, adjusted to an appropriate distance, the camera can capture the image seen by the human eye and process it. In order to achieve versatility, the existing mobile phone camera fixing bracket can be used with various sizes of mobile phones and eyepieces of various sizes. The structure of the mobile phone camera fixing bracket is generally complicated, and it is troublesome to realize the connection with the eyepiece or mobile phone. difficulty
