Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 2 As shown, it is a structural schematic diagram of the doorway device according to the first embodiment of the present invention. The doorway device includes a first tube 100 , a second tube 110 , a refraction element 120 and a second optical lens 130 .

[0022] The first tube 100 can pass through the through hole 142 of the door 140 from the first surface 141 of the door 140 , and the first lens 150 is disposed in the first tube 100 . Wherein, the first pipe member 100 includes a first abutment portion 101 and a first tubular portion 102, the outer diameter of the first abut...

Abstract

The invention discloses a door eye device, which at least comprises a first pipe fitting (100), a second pipe fitting (110), a first lens (150), a refractive element (120) and a second optical lens (130), wherein the first pipe fitting (100) and the second pipe fitting (110) respectively penetrate through a door panel through hole (142) through opposite surfaces of a door panel (140) and are in threaded connection in the through hole (142), and the first lens (150) is arranged in the first pipe fitting (100); and a light entrance surface (121) of the refractive element (120) is butted against the second pipe fitting (110). After an image enters the refractive element (120) through the first lens (150), the first pipe fitting (100), the second pipe fitting (110) and the light entrance surface (121), the image is refracted by a refractive curved surface (123) and is emitted from a light exit surface (122), and finally enters the second optical lens (130) for imaging. The technical scheme provided by the invention is implemented to effectively correct image deformation and distortion and other side effects caused by the wide-angle effect of the first lens.

Description

technical field [0001] The present invention relates to a doorway device, in particular to a doorway device using a refraction element. Background technique [0002] Usually, the door panels of houses, apartments or buildings are provided with eyelet devices, which enable the homeowner to check the visitors or the situation outside the door through the door eye device without opening the door. [0003] Common door opening devices such as figure 1 As shown, a first tube 10 and a second tube 20 are included, a lens 11 is installed in the first tube 10, and rings 11 and 21 with enlarged outer diameters are respectively provided at one end of the first tube 10 and the second tube 20 . During installation, the first pipe 10 and the second pipe 20 respectively penetrate the through hole 31 from the opposite surface of the door panel 30 and are screwed and clamped and fixed in the door panel 30, so that the user can see through one end of the second pipe 20 and the lens 11. to t...
