Description

Technical Field

[0001] The utility model relates to the technical field of binoculars, in particular to a pair of binoculars. Background Art

[0002] With the advancement of telescope technology, binoculars have become widely used for observing distant scenery because they provide stereoscopic vision and a comfortable viewing experience. However, the fixed positions of the two barrels in traditional binoculars make them incompatible with different users due to differences in interpupillary distance (IPD). To address this problem, some binoculars with adjustable barrels have appeared on the market. These use an adjustment mechanism to allow users to adjust the distance between the barrels based on their individual interpupillary distance. For example, patent document CN217739606U discloses a continuously variable magnification binocular that adjusts the distance between the two barrels by rotating the barrels on their central axis. However, these adjustment mechanisms in the prior art have some shortcomings. While they can adjust the distance between the barrels to a certain extent, they often fail to maintain a stable position of the two barrels after adjustment. This instability can cause the barrels to shift during use, affecting observation quality and even requiring frequent readjustment, causing inconvenience to the user. Utility Model Content

[0003] The embodiment of the utility model provides a binoculars to solve the problem in the prior art that the positions of the two lens barrels of the binoculars cannot be fixed stably for a long time.

[0004] To achieve the above-mentioned object, the embodiment of the present utility model adopts the following technical solution: a binoculars, comprising a central axis and two monocular bodies, a connecting seat is provided on one side of the monocular body, the connecting seat is rotatably connected to the central axis, and a first gear disk is provided on the connecting seat;

[0005] A second toothed disc is provided at the axis center of the central shaft, and the tooth shape of the second toothed disc is consistent with that of the first toothed disc. A locking screw for fixing the second toothed disc on the central shaft is provided at the end of the second toothed disc away from the central shaft, and a first mounting hole for embedding the locking screw is provided at the axis center of the central shaft, and an internal thread is provided in the first mounting hole. When the locking screw fixes the relative position of the second toothed disc and the central shaft, the second toothed disc and the first toothed disc engage with each other, so that the relative position of the second toothed disc and the first toothed disc is fixed.

[0006] Furthermore, a second mounting hole is provided on the monocular body, and a countersunk screw is provided on the first gear disc. When the first gear disc is installed, the countersunk screw passes through one end of the first gear disc and extends into the second mounting hole.

[0007] Furthermore, a spring is provided between the second sprocket and the central shaft.

[0008] The beneficial effects of the utility model are:

[0009] The binoculars provided by the utility model fix the second gear disc on the central axis by means of a locking screw, thereby limiting the position of the first gear disc on the connecting seat, so that the connecting seat and the monocular body will not rotate on the central axis, and the distance between the two monocular bodies will not change.

[0015] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0016] like Figure 1-3 As shown, an embodiment of the present invention provides a pair of binoculars, comprising a central axis 1 and two monocular bodies 2. A connecting seat 3 is provided on one side of the monocular body 2. The connecting seat 3 is rotatably connected to the central axis 1. The position of the monocular body 2 is adjusted by adjusting the position of the connecting seat 3, so that the binoculars can adapt to the pupil distance of different users. A first gear wheel 4 is provided on the connecting seat 3.

[0017] A second toothed disc 5 is provided at the axis center of the central shaft 1. The tooth shape of the second toothed disc 5 is consistent with that of the first toothed disc 4. A locking screw 6 for fixing the second toothed disc 5 to the central shaft 1 is provided at the end of the second toothed disc 5 away from the central shaft 1. A first mounting hole 11 for embedding the locking screw 6 is provided at the axis center of the central shaft 1. An internal thread is provided in the first mounting hole 11 to realize a fixed connection between the central shaft 1 and the locking screw 6. When the locking screw 6 fixes the relative position of the second toothed disc 5 and the central shaft 1, the second toothed disc 5 and the first toothed disc 4 engage with each other, so that the relative position of the second toothed disc 5 and the first toothed disc 4 is fixed.

[0018] Specifically, the user first rotates the monocular body 2 on the central axis 1, and then adjusts the relative position of the monocular body 2 and the central axis 1 so that the telescope can adapt to the user's pupil distance, and rotates the locking screw 6 on the central axis 1 until it is tightened, so that the second gear disc 5 moves toward the central axis 1, so that the second gear disc 5 and the first gear disc 4 engage with each other, limiting the rotation of the first gear disc 4, so that the relative position of the monocular body 2 and the central axis 1 will not change.

[0019] To facilitate the connection between the first gear disc 4 and the monocular body 2, in a preferred embodiment of the present utility model, a second mounting hole 31 is provided on the monocular body 2. The second mounting hole 31 is used to install fixing parts such as bolts and screws. A countersunk screw 7 is provided on the first gear disc 4. When installing the first gear disc 4, the countersunk screw 7 passes through one end of the first gear disc 4 and extends into the second mounting hole 31, thereby realizing a fixed connection between the first gear disc 4 and the monocular body 2.

[0020] Taking into account the need to readjust the position of the monocular body 2, in order to facilitate the second gear disc 5 to disengage from the outer wall of the first gear disc 4, in a preferred embodiment of the present utility model, a spring 8 is provided between the second gear disc 5 and the central axis 1. When the locking screw 6 is tightened, the spring 8 is compressed, so that the spring 8 provides additional friction (the friction of the threaded contact surface is increased in the compressed state of the spring 8), thereby enhancing the locking effect of the locking screw 6, so that the first gear disc 4 and the second gear disc 5 can maintain an engaged state even under vibration conditions. When the locking screw 6 is loosened, the spring 8 stretches to generate a thrust, causing the second gear disc 5 to disengage from the first gear disc 4.

[0021] To sum up, the binoculars fix the second gear disc 5 on the central axis 1 by means of the locking screw 6, thereby limiting the position of the first gear disc 4 on the connecting seat 3, so that the connecting seat 3 and the monocular body 2 will not rotate on the central axis 1, and the distance between the two monocular bodies 2 will not change.

[0022] The above-described embodiments merely represent implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
