[0019] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.

[0020] As Figures 1 to 4 shown, it is a kind of adjustable binoculars provided by the utility model, the adjustable binoculars include two lens barrels 10, connecting portion 20, two protective covers 30 and two end caps 40, the connecting portion 20 is connected to two lens barrels 10, two protective covers 30 are installed on the rear side end of two lens barrels 10, and two end caps 40 are covered on the front side end of two lens barrels 10.

[0021] The lens barrel 10 includes body portion 11, objective lens assembly 12 and eyepiece assembly 13, the objective lens assembly 11 is arranged at the front end of body portion 11, and the eyepiece assembly 13 is arranged at the rear end of body portion 11.The end cap 40 is covered on the front end of objective lens assembly 12 to protect objective lens, and the protective cover 30 is detachably installed on the eyepiece assembly 13 and extends to the outside end, the protective cover 30 not only can protect the eyepiece assembly 13, but also can protect eyes, reduce external stray light interference, and can fix the binoculars, reduce shaking, make observation more clear and stable, and improve observation comfort.

[0022] The outside end of the eyepiece assembly 13 is provided with a mounting portion 131, an outer thread is arranged on the outer surface of the mounting portion 131, and the protective cover 30 is mounted on the mounting portion 131 by locking piece 50.The protective cover 30 is arranged in a horn shape from the mounting end to the free end, and the outside end of the protective cover 30 covers the outside of the eye to block the external light of the eye.The end of the protective cover 30 is provided with a positioning portion 31, the positioning portion 31 is a tubular structure and is communicated with the horn structure of the protective cover 30, an inner thread is arranged in the tube, and an outer thread is arranged outside the tube.A plurality of position adjusting grooves 311 are arranged on the positioning portion 31 and are evenly arranged along the circumferential direction of the positioning portion 31.The locking piece 50 is hollow, the inner side of the locking piece 50 is provided with an inner thread, and the inner diameter of the locking piece 50 includes a lead-in end 51 and a limiting end 52, which are gradually reduced from the lead-in end 51 to the limiting end 52.

[0023] The protective cover 30 comprises a main body 32 and a buffer sleeve 33 arranged outside the main body 32. The main body 32 is in the shape of the protective cover 30 and is arranged in a sheet shape. Further, the main body 32 is made of plastic material and is injection molded. The main body 32 is provided with an elongated portion 321 corresponding to the outer corner of the eye and an extension portion 322 corresponding to the lower part of the eye. The elongated portion 321 and the extension portion 322 are both provided with through holes 323 penetrating from the inside to the outside. The through holes 323 are micro-holes with small diameters. The elongated portion 321 and the extension portion 322 are arranged outside the visual field of the eye and do not affect the light in the protective cover 30. In addition, the arrangement of the through holes 323 reduces the hardness of the main body 32 in this area and makes it relatively soft. The edges of the main body 32 are more fitted to the face.

[0024] The buffer sleeve 33 is made of soft rubber material and comprises an inner portion 331 and an outer portion 332. The shape of the inner portion 331 is consistent with the shape of the inner surface of the main body 32, which is fitted to the inner surface of the main body 32. Specifically, the inner surface of the main body 32 is provided with a limiting groove 324 at the lower end, and the inner surface of the bottom of the inner portion 331 is provided with a convex ring 3311 which is embedded in the limiting groove 324, thereby making the installation of the buffer sleeve 33 more stable.

[0025] The outer portion 332 is outwardly folded and arranged on the outer surface of the main body 32. The outer portion 332 is arranged on the main body 32 below the convex portion 3321, which can limit the outer portion 332 and further improve the stability of the installation of the buffer sleeve. The buffer sleeve 33 is provided with corresponding holes corresponding to the through holes 323 of the main body 32 to facilitate air circulation. In this embodiment, the buffer sleeve 33 is made of silicone material. Further, the buffer sleeve 33 is made of soft silicone material, which can improve the comfort and fit of the eye when in contact with the eye. In addition, the buffer sleeve 33 can be replaced with thicker or thinner material according to the needs of different users. New buffer sleeves 33 can also be replaced according to different users to improve the hygiene of use.

The front end of the objective lens assembly 12 is provided with a magnetic member (not shown), and the outer surface of the end cover 40 is provided with a metal sheet. When in use, the end cover 40 is opened and the metal sheet on the outer surface is attracted to the magnetic member, thereby avoiding the loss of the lens cover and avoiding the shaking of the lens cover affecting the observation experience.

[0027] In use, the locking member 31 is sleeved on the inside of the mounting portion 131, and the small inside diameter end is on the inside, and the protective cover 30 is sleeved on the required position on the outside of the mounting portion 131, if the ocular lens assembly 13 needs to be installed close to some distance, the protective cover 30 needs to be installed on the inside end of the mounting portion 131, if the ocular lens assembly 13 needs to be far away, the protective cover 30 needs to be installed on the outside end of the mounting portion 131, and the specific position is set according to requirements, so that the flexibility of installation is better. The locking member 31 is screwed from the inside to the outside of the protective cover 30, and the internal thread of the protective cover 30 is locked on the external thread of the mounting portion 131. In this embodiment, the inside diameter of the protective cover 30 is greater than the outside diameter of the mounting portion 131, so that the protective cover 30 can be freely rotated to the required angle on the mounting portion, and it can be adjusted at any position according to individual needs.

[0028] In summary, the protective cover 30 of the utility model can be freely adjusted in angle and position, so that it has higher flexibility and can be adjusted for distance by people with different vision and different preferences. The protective cover 30 not only protects the ocular lens assembly, but also protects the eyes, effectively reduces the influence of external light, reduces glare interference, improves observation comfort, makes observation clearer and more stable, and helps to fix the telescope and reduce shaking. In addition, the protective cover 30 is provided with a lengthening portion 321 and an extension portion 322, the lengthening portion 321 and the extension portion 322 are arranged outside the line of sight area, and the upper portions of the lengthening portion 321 and the extension portion 322 are provided with micro-holes penetrating in and out to avoid water vapor in the protective cover 30 affecting use. The setting of the buffer sleeve 33 not only improves the contact comfort, but also makes the contact with the eye more conformable, avoiding large light transmission gaps.
