Binoculars, comprising two housings (1). The two housings (1) are fixed to one another by a twisting column (2) and the outer sides of the two housings (1) can be moved closer together or farther apart by twisting the two housings (1). Fastened at the front end of each housing (1) is an objective lens holder (3), the objective lens holder (3) having an objective lens fastened therein. An ocular lens holder (4) is fastened at the rear end of each housing (1), a prism fixing base (6) is fastened at the front end of the ocular lens holder (4), said prism fixing base (6) being used to fasten a prism (5), and an ocular lens is fastened on the ocular lens holder (4) at the rear end of the prism (5). Screw holes are provided on the ocular lens holders (4) at the top parts of the prisms (5) and on the housings (1), flat head screws (7) rotate into the screw holes and press against the prisms (5), and by means of the rotation of the flat head screws (7), the positions of the prisms (5) are corrected so that the prisms (5) are placed in optimal positions, and ideal binocular usage results are ensured.

Description

telescope Technical field

The invention relates to a telescope.

Background technique

A telescope is an optical device used to observe distant objects, and can help people see objects that are invisible to the naked eye, and is widely used in daily life. The existing telescope contains two bodies, namely the binoculars of the telescope. The two bodies are provided with a torsion column between them, which can be twisted to adjust the distance of the eyepiece of the telescope. The body is equipped with an eyepiece, an objective lens and a prism. The optical function is used to see distant objects. The above prism is between the eyepiece and the objective lens. The prism is an important part of the optical lens. Because the lens of the existing prism is thick, it reflects light through several surfaces, and the prism is installed when the telescope is produced. It is inevitable that there will be a slight deviation in the position of the prism, so that the position of the prism is not in the best position, which makes the objects we see darker and leads to unclear vision.

Summary of the invention

In view of the defects of existing telescopes, the technical problem to be solved by the present invention is to provide a telescope whose prism position can be adjusted appropriately.

In order to achieve the above objective, according to one aspect of the present invention, the present invention is achieved through the following technical measures: a telescope, including; a body, the body is two, the two bodies are fixed by a torsion column, so that the two The main body can be rotated along the torsion column. The front end of the main body is provided with an objective lens holder, the objective lens is fixed in the objective lens holder, the rear end of the main body is provided with an eyepiece holder, and the eyepiece holder is provided with an eyepiece and a prism. There are screw holes on the eyepiece frame and the body, and the flat-bottomed screws rotate through the screw holes to resist the prism.

The telescope is designed with flat-bottomed screws, and the angle of the prism can be corrected by simply rotating the flat-bottomed screws.

Further, the screw hole on the body is movably closed by a sealing plug. The above design firstly plays a role of dust prevention, and at the same time does not affect the beauty of the telescope.

Compared with the prior art, the present invention has the advantages that the prism can be adjusted through flat-bottomed screws, so that the prism is in the best position, and the telescope has the most ideal use effect.

detailed description

Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other if there is no conflict.

In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", The orientation or positional relationship indicated by "bottom", "top", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have The specific orientation, construction and operation in a specific orientation cannot be understood as a limitation of the present invention.

Example 1

Please refer to Figure 1. The telescope provided in this embodiment includes two bodies 1. The two bodies 1 are the binoculars of the telescope. The two bodies 1 are fixed by a torsion column 2, and the two bodies 1 are twisted to make the two bodies 1. 1 The outer side can be close to or far away, the front end of each body 1 is fixed with an objective lens holder 3, the objective lens is fixed in the objective lens holder 3, the rear end of each body 1 is fixed with an eyepiece holder 4, and the front end of the eyepiece holder 4 is fixed with a prism The fixing seat 6, the prism fixing seat 6 is used to fix the prism 5, the eyepiece holder 4 at the back of the prism 5 is fixed with an eyepiece, and the eyepiece holder 4 on the top of the prism 5 and the body 1 are provided with screw holes, and the flat-bottom screw 7 is rotated into the screw hole Then, when the angle or position of the prism 5 is not very positive, you can make proper corrections by rotating the flat-bottom screw 7 to make the position of the prism 5 best. At the same time, the above-mentioned screw hole is movably closed by the sealing plug to prevent dust.

In summary, the telescope with the structure of this embodiment can ensure the most ideal use effect.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and changes. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
