Embodiment 1

[0038] refer to Figure 1-9 It is an embodiment of the present invention, disclosing a diopter and focal length adjustment device for binoculars, including a central axis 11, a left mirror body 12, a right mirror body 13, a hand wheel lower block 14, a viewing Degree hand wheel 15, diopter adjustment sleeve 16, right pull rod 17, adjustment screw sleeve 18, left pull rod 19, focusing hand wheel 20, hand wheel pressure ring 21, screw 22, the central axis 11 and the left mirror body 12, The right mirror body 13 is connected, and the central shaft 11 cooperates with the convex key 121 of the left mirror body 12 through the keyway 111, so that the central shaft 11 and the left mirror body 12 are fixed, and the right mirror body 13 rotates around the central shaft 11 at an angle β;

[0039] The outer wall of the central axis 11 is sleeved with a diopter handwheel 15 that can rotate relative to the central axis 11, a handwheel lower stopper 14 is provided below the diopter handwheel...

Embodiment 2

[0050] refer to Figure 10 , on the basis of Embodiment 1, the diopter adjustment sleeve 23 is set through a chute, the focusing screw sleeve 24 is provided with a threaded hole and a guide nail 25, and the guide nail 25 is passed through the diopter adjustment Cover 23 logical chute, pack in the 24 threaded holes of described focusing screw sleeve, all the other are exactly the same with embodiment 1. This embodiment is beneficial to the use of metal materials to manufacture parts to meet the requirements of some users who need all-metal handwheels. The chute and guide nails can be set in one or more groups according to the size of the structure.

Abstract

The invention discloses a diopter and focal length center adjusting device for a binocular telescope. The device comprises a center shaft, a left lens body and a right lens body are respectively arranged on two sides of the center shaft, the center shaft and the left lens body are fixed together, and the right lens body can rotate around the center shaft. The outer wall of the center shaft is sleeved with a diopter hand wheel capable of rotating relative to the center shaft, the lower portion of the diopter hand wheel is provided with a hand wheel lower blocking piece, the center shaft is provided with a blocking table, and the hand wheel lower blocking piece sleeves and is fixed to the outer wall of the blocking table. A diopter adjusting sleeve is arranged above the diopter hand wheel, and the diopter adjusting sleeve can synchronously rotate and move up and down along with the diopter hand wheel. The inner side of the diopter adjusting sleeve is connected with the outer circle of a focusing screw sleeve in a sliding fit mode. Compared with the prior art, diopter adjustment and focal length adjustment are carried out on the center shaft, and the device is convenient to assemble, low in cost, reliable in adjustment and capable of being widely applied to common telescopes.

Description

technical field [0001] The invention relates to the technical field of telescopes, in particular to a diopter and focus adjustment device for binoculars. Background technique [0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. Hand-held binoculars are one of the most widely used binoculars. In the binoculars, the diopter adjustment is required to balance the vision errors of the left and right eyes, and the focal length needs to be adjusted to observe objects at different distances. [0003] Most of the diopter adjustments of existing ordinary telescopes are at the eyepiece position, and the focal length adjustment is at the central axis position, which requires two hands to operate, which is inconvenient to use. The diopter and focal length of a few high-end telescopes are adjusted on the central axis, which can be operated with one hand and is easy to use. However, this adjustment structure is on...
