Description

Technical Field

[0001] This utility model belongs to the field of imaging equipment technology, specifically relating to an eyepiece and imaging device that can be rotated and positioned 360°. Background Technology

[0002] Most eyepieces use direct adhesive or grooved sliding for the eyecup, making 360° rotation and positioning unreliable. During use, the eyecup is prone to jamming or loosening, and the rotation feel is unpleasant, affecting the user experience. Furthermore, achieving 360° rotation and positioning requires many parts, resulting in a relatively complex structure and low assembly efficiency. Additionally, when focusing the eyepiece, the eyecup cannot move with the lens barrel, posing a risk of eye contact without increasing the eyecup height. Utility Model Content

[0003] The purpose of this invention is to provide an eyepiece that can be rotated and positioned 360° in an eye mask, which can at least solve some of the defects existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An eyepiece with a 360° rotatable positioning eyepiece includes an eyepiece tube, a tube support is provided on the outer side of one end of the eyepiece tube, and an eyepiece that can rotate circumferentially relative to the eyepiece tube is coaxially provided at the other end of the eyepiece tube via an eyepiece adjustment assembly. A focusing assembly is provided on the outer wall of the eyepiece tube between the tube support and the eyepiece.

[0006] Furthermore, the eye mask adjustment assembly includes an inner eye mask seat and an outer eye mask seat. The inner eye mask seat is fixedly connected to the outer wall of the eyepiece barrel, and the outer eye mask seat is convexly connected to the inner eye mask seat. The eye mask is connected to the outer eye mask seat.

[0007] Furthermore, the goggle adjustment assembly also includes a limiting member for restricting the axial relative displacement between the outer goggle seat and the inner goggle seat.

[0008] Furthermore, the outer wall of the inner seat of the eye mask is provided with an inner toothed ring in the circumferential direction, and the inner wall of the outer seat of the eye mask is provided with a number of outer toothed ring segments at intervals along its circumference, each of the outer toothed ring segments meshing with the inner toothed ring.

[0009] Furthermore, a limiting block is provided between two adjacent outer toothed ring segments on the outer seat of the eye mask, which can engage with the inner toothed ring.

[0010] Furthermore, the inner seat of the goggles is provided with a positioning structure for positioning and connecting with the goggles.

[0011] Furthermore, the positioning structure is an arc-shaped buckle located on one side of the inner seat of the eye mask near the eye mask, and the eye mask is provided with an annular groove that cooperates with the arc-shaped buckle.

[0012] Furthermore, the focusing assembly includes a focusing wheel, a focusing wheel insert, a focusing wheel retaining ring, and a focusing guide pin. One end of the focusing guide pin passes through the lens barrel support and is fixedly connected to the eyepiece barrel. The lens barrel support is provided with a limiting slot for the lens barrel support and the focusing guide pin to move relative to each other along the axial direction. The other end of the focusing guide pin is fixedly connected to the focusing wheel insert. The focusing wheel retaining ring is disposed between the focusing wheel insert and the eyecup adjustment assembly, and the focusing wheel retaining ring is threadedly connected to the lens barrel support. The focusing wheel is coaxially sleeved on the outside of the focusing wheel insert.

[0013] Furthermore, a first sealing ring is provided between the lens barrel support and the eyepiece barrel, and a second sealing ring is provided on the outer wall of the lens barrel support for sealing with external equipment.

[0014] In addition, this utility model also provides an imaging device, including the eyepiece of the above-mentioned eyecup that can be rotated and positioned 360°.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) This utility model fixes the eyecup to the eyepiece barrel by designing an eyecup focusing assembly, so that the eyecup can move together with the eyepiece barrel during the focusing process, avoiding the risk of the eyepiece touching the eyeball. At the same time, the eyecup can also be individually rotated to any angle by adjusting the eyecup focusing assembly. Moreover, the entire eyepiece structure achieves the required focusing and eyecup angle adjustment functions, requires fewer parts, is easy to install, and has high assembly and production efficiency.

[0017] (2) The eye mask inner seat and eye mask outer seat of the eye mask focusing assembly of this utility model are engaged and matched, so that the eye mask can be turned at any angle with a clear feel and the stopping position is not easily slipped by accidental touch; at the same time, the focusing assembly is optimized and the focusing is smoother, and the number of focusing turns and the focusing stroke can be increased or decreased according to optical needs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, abutting connections, or integral connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" or "several" means two or more.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an eyepiece with a 360° rotatable and positionable eyepiece, including an eyepiece tube 6. A tube support 1 is provided on the outer side of one end of the eyepiece tube 6. An eyepiece 3, which can rotate circumferentially relative to the eyepiece tube 6, is coaxially mounted on the other end of the eyepiece tube 6 via an eyepiece adjustment assembly. A focusing assembly 2 is disposed on the outer wall of the eyepiece tube 6 between the tube support 1 and the eyepiece 3. Optical elements are arranged inside the eyepiece tube 6; their specific structure will not be described in detail here. During the focusing process of the eyepiece in this embodiment, the focusing assembly 2 drives the eyepiece tube 6 to move relative to the tube support 1. During this process, since the eyecup 3 is connected to the eyepiece tube 6, the eyecup 3 can move together with the eyepiece tube 6, avoiding the risk of the eyepiece touching the eyeball. At the same time, through the adjustment of the eyecup focusing assembly, the eyecup 3 can also be independently rotated to any angle relative to the eyepiece tube 6 in the circumference. Moreover, the entire eyepiece structure achieves the required focusing and eyecup angle adjustment functions, requires fewer parts, is easy to install, and has high assembly and production efficiency.

[0031] As one specific implementation method, such as Figures 3 to 6 As shown, the eye mask adjustment assembly includes an inner eye mask seat 9 and an outer eye mask seat 8. The inner eye mask seat 9 is fixedly connected to the outer wall of the eyepiece barrel 6. The connection between the inner eye mask seat 9 and the eyepiece barrel 6 can be, but is not limited to, a threaded connection. By fixing the inner eye mask seat 9 to the eyepiece barrel 6, the eye mask 3 can move together with the eyepiece barrel 6. The eye mask is connected to the outer eye mask seat. For example, in some embodiments, the connection between the eye mask 3 and the outer eye mask seat 8 can be achieved by setting an annular groove on the inner side of the eye mask 3, and the outer eye mask seat 8 is engaged and fixed in the annular groove. At the same time, the outer eye mask seat and the inner eye mask seat are designed to be drivenly connected. In some embodiments, the outer eye mask seat 8 and the inner eye mask seat 9 are designed to be coaxially meshed. The outer eye mask seat 8 and the inner eye mask seat 9 can move relative to each other, so that the eye mask 3 can also be independently rotated at any angle relative to the eyepiece barrel 6 in the circumferential direction. In this embodiment, the meshing design of the inner seat 9 and the outer seat 8 of the eye mask makes the eye mask 3 easy to rotate at any angle, and the rotation and positioning are not easily affected by accidental slippage, which greatly improves the user experience.

[0032] In an optional embodiment, the outer wall of the inner seat 9 of the eye mask is provided with an inner toothed ring 17, and the inner wall of the outer seat 8 of the eye mask is provided with a plurality of outer toothed ring segments 15 spaced apart along its circumference, and each of the outer toothed ring segments 15 meshes with the inner toothed ring 17; in this embodiment, the outer seat 8 of the eye mask adopts an intermittent and discontinuous outer toothed ring design, which can reduce the resistance of rotation of the eye mask 3 on the one hand, and reduce the processing difficulty of the outer seat 8 of the eye mask on the other hand.

[0033] Furthermore, the eye mask adjustment assembly also includes a limiting member for restricting the axial relative displacement between the outer eye mask seat 8 and the inner eye mask seat 9. In some embodiments, the limiting member may be a limiting block 16 that can engage with the inner toothed ring 17 between two adjacent outer toothed ring segments 15 on the outer eye mask seat 8. Specifically, in this embodiment, the limiting block 16 is designed with a U-shaped structure. When the inner eye mask seat 9 and the outer eye mask seat 8 are assembled, the inner toothed ring 17 of the inner eye mask seat 9 engages in the groove of the limiting block 16, restricting the relative displacement between the inner eye mask seat 9 and the outer eye mask seat 8 along their axial direction. At the same time, the limiting block 16 does not restrict the relative rotation between the inner eye mask seat 9 and the outer eye mask seat 8 along their circumference, ensuring that the eye mask 3 can be rotated and positioned at any angle in the circumference.

[0034] Preferably, the inner seat 9 of the goggles is provided with a positioning structure for positioning and connecting with the goggles 3. In some embodiments, this positioning structure may be an arc-shaped buckle 18 provided on the side of the inner seat 9 near the goggles 3, and the goggles 3 is provided with an annular groove that cooperates with the arc-shaped buckle 18; the cooperation between the arc-shaped buckle 18 and the annular groove can play a positioning role in the installation of the goggles 3. Specifically, in this embodiment, there are two arc-shaped buckles 18, which are symmetrically arranged at intervals along the circumference of the inner seat 9 of the goggles.

[0035] As one specific implementation method, such as Figure 2 and Figure 3As shown, the focusing assembly 2 includes a focusing wheel 7, a focusing wheel insert 13, a focusing wheel pressure ring 14, and a focusing guide pin 5. One end of the focusing guide pin 5 passes through the lens barrel support 1 and is fixedly connected to the eyepiece barrel 6. The other end of the focusing guide pin 5 is fixedly connected to the focusing wheel insert 13. The lens barrel support 1 is provided with a limiting slot 4 for the lens barrel support 1 and the focusing guide pin 5 to move relative to each other along the axial direction. The focusing guide pin 5 passes through the limiting slot 4. Specifically, in this embodiment, the limiting slot 4 is an oblong hole, and the length direction of the oblong hole is horizontal. The focusing wheel is arranged axially along the lens barrel support 1; the focusing wheel retaining ring 14 is disposed between the focusing wheel insert 13 and the eyepiece adjustment assembly, and the focusing wheel retaining ring 14 is threadedly connected to the lens barrel support 1; the focusing wheel 7 is coaxially sleeved on the outside of the focusing wheel insert 13; in this embodiment, rotating the focusing wheel 7 will drive the focusing guide pin 5 and the eyepiece barrel 6 to move back and forth (i.e., axially) relative to the lens barrel support 1, thereby realizing the rotation focusing function, making focusing smoother, and the number of focusing rings and focusing stroke can be increased or decreased according to optical needs.

[0036] Preferably, the focusing wheel 7 has an interface portion at one end near the eye mask 3. The interface portion is coaxially sleeved on the outside of the eye mask 3, and the eye mask 3 can be limited by the interface portion of the focusing wheel 7. Specifically, the eye mask 3 has a trumpet-shaped structure with a gradually expanding outer diameter, and the interface portion of the focusing wheel 7 is correspondingly designed with a gradually expanding inner diameter.

[0037] To facilitate the installation of the eyepiece into the device in this embodiment, the end of the lens barrel support 1 away from the focusing assembly 2 is provided with a connecting part 11 for connecting to an external device. Specifically, the connecting part 11 in this embodiment can be, but is not limited to, a connecting thread provided on the outer wall of the lens barrel support 1. When the eyepiece is installed into the external device, the connecting thread of the lens barrel support 1 is aligned with the thread of the eyepiece mounting position of the external device and screwed in to lock it, which is convenient for installation.

[0038] Furthermore, a first sealing ring 10 is provided between the lens barrel support 1 and the eyepiece barrel 6, and a second sealing ring 12 for sealing with external equipment is provided on the outer side wall of the lens barrel support 1.

[0039] The eyepiece assembly process in this embodiment is as follows: First, the eyepiece barrel 6 is installed into the barrel support 1, a sealing ring is installed, and the focusing guide pin 5 is locked in place. Then, the focusing wheel insert 13 and the focusing wheel 7 are screwed in along the focusing guide pin 5 and fitted onto the barrel support 1. The focusing wheel retaining ring 14 is then screwed in to lock the barrel support 1. Finally, the inner toothed ring of the eyecup inner seat 9 is aligned with the toothed ring of the eyecup outer seat 8 and pressed in until they fit, completing the eyecup adjustment assembly. The eyecup 3 is then fastened onto the eyecup adjustment assembly, and the eyecup inner seat 9 of the eyecup adjustment assembly is aligned with the eyepiece barrel 6 and screwed in to lock, completing the eyepiece assembly. The entire eyepiece structure in this embodiment achieves the required focusing and eyecup angle adjustment functions, requires fewer parts, is easy to install, and has high assembly production efficiency.

[0040] In addition, this embodiment also provides an imaging device, including the eyepiece of the aforementioned goggles that can be rotated and positioned 360°. This imaging device can be a telescope, night vision device, microscope, etc.
