Description

Technical Field

[0001] The utility model relates to an eyepiece eye mask and an imaging device, belonging to the technical field of imaging products. Background Art

[0002] Infrared thermal imaging, low-light imaging, white-light imaging and other products observe the display screen through the eyepiece. In order to prevent the human eye from directly contacting the eyepiece glass lens, the eyepiece generally has a certain exit pupil distance. When the human eye is at the exit pupil distance to observe the display screen, an eye mask is required for light shielding.

[0003] However, in order to ensure that the eyepiece eye masks on the market do not fall off, most of them are fixed together with the eyepiece by gluing or locking, and are not removable, which is not conducive to cleaning the dust on the eyepiece glass. Or the eyepiece and the eyepiece are not fixedly connected, and the eyepiece is easy to fall off. Since the eyepiece and the eyepiece are not firmly fixed, when the user wants to pick up the imaging product by grabbing the eyepiece, the eyepiece will fall off and the entire thermal imaging device will fall and be damaged.

[0004] In summary, how to ensure that the eye mask and the eyepiece are easy to disassemble and prevent the eye mask and the eyepiece from falling off when the user wants to pick up the imaging product by grabbing the eye mask is a problem that currently needs to be solved by those skilled in the art. Utility Model Content

[0007] On the basis of the above technical solution, the present invention can also be improved as follows:

[0008] Furthermore, the inner diameter of the connecting portion is smaller than the outer diameter of the hand wheel, and the connecting portion is made of elastic material.

[0009] Furthermore, at least one raised ring is axially arranged on the inner side of the connecting portion, and grooves respectively matched with the raised rings are axially arranged on the outer side of the eyepiece.

[0010] Furthermore, the raised ring is a continuous ring structure or a discontinuous ring structure composed of a plurality of arc-shaped protrusions.

[0011] Furthermore, a knurling pattern extending in the axial direction is provided on the outer side of the hand wheel.

[0012] Furthermore, at least one blank area between the knurling patterns is provided on the outer side of the hand wheel.

In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Please combine Figure 1 , Figure 2 and Figure 3 The core of the utility model is to provide an eyepiece eye mask, which is easy to disassemble and not easy to fall off. Another core of the utility model is to provide an imaging device including the above-mentioned eyepiece eye mask, which is convenient for disassembling the eye mask and convenient for taking the imaging device through the eye mask.

[0029] Example 1

[0030] An eyepiece eye mask comprises an eyepiece 1 and an eye mask 2, wherein the eye mask 2 is detachably connected to the eyepiece 1, and after the eye mask 2 is removed from the eyepiece 1, it is convenient to clean the glass of the eyepiece 1; in addition, the eye mask 2 is connected to the eyepiece 1 through an interference force, and has a certain connection strength, so that when a small force is applied, the eye mask 2 is not easy to loosen from the eyepiece 1, and when a user grabs the eye mask 2 to pick up a thermal imaging product, the eye mask 2 is not easy to fall off from the eyepiece 1, thereby reducing the risk of the imaging device falling and being damaged.

[0031] The eyepiece 1 includes a hand wheel 11, and the eyepiece 1 can be focused by rotating the hand wheel 11. This focusing method and focusing structure are relatively mature in the field of imaging equipment and will not be described in detail here; the eye mask 2 is made of elastic material, preferably silicone material in this embodiment, and the eye mask 2 is integrally injection molded; the eye mask 2 includes an observation portion 21 and a connecting portion 22, the inner side of the connecting portion 22 is detachably connected to the outer side of the hand wheel 11, the inner diameter of the connecting portion 22 is smaller than the outer diameter of the hand wheel 11, and the connecting portion 22 and the hand wheel 11 are connected together by an interference fit, and the connecting portion 22 undergoes elastic deformation, which can be well fixed to the hand wheel 11, and it is also convenient to install and disassemble the eye mask 2. When the eye mask 2 needs to be disassembled, due to the shrinkage of the silicone itself, it is convenient to remove the eye mask 2 from the eyepiece 1, thereby facilitating the cleaning of the glass of the eyepiece 1.

[0032] The outer side of the handwheel 11 is provided with a knurling 111 extending in the axial direction, and the surface of the inner side of the connecting part 22 that contacts the knurling 111 is a smooth surface. The knurling 111 can increase the friction between the connecting part 22 to prevent the eye mask 2 from idling when the rotating eye mask 2 drives the handwheel 11 to focus. The inner side of the connecting part 22 is set to a smooth surface, which can adjust the friction between the handwheel 11 and the connecting part 22, and reduce the problem that the connecting part 22 is difficult to be pulled out of the handwheel 11 due to excessive friction between the handwheel 11 and the connecting part 22; the outer side of the handwheel 11 is provided with a blank area 112 located between the knurling 111, and the provision of the blank area 112 can ensure that the interference force between the handwheel 11 and the connecting part 22 is within a reasonable range.

[0033] A second knurling 221 is provided on the outer side of the connecting portion 22. When a user rotates the hand wheel 11 by rotating the connecting portion 22, the second knurling 221 can increase the friction between the user's hand and the connecting portion 22, thereby reducing the problem of slipping.

[0034] Two raised rings 23 are axially arranged on the inner side of the connecting portion 22, and the raised ring 23 is a continuous annular structure. The outer side of the eyepiece 1 is provided with card slots 24 respectively matched with the two raised rings 23, wherein one card slot 24 is arranged at one end of the hand wheel 11 close to the observation portion 21, and the other card slot 24 is arranged on the eyepiece 1, and the hand wheel 11 plays a blocking and limiting role on the raised ring 23 connected in the other card slot 24, and the raised rings 23 are respectively located at both ends of the connecting portion 22, and the raised rings 23 are inserted into the card slots 24, which can improve the limiting effect between the eye mask 2 and the eyepiece 1 and prevent the eye mask 2 from moving along the axial direction. At the same time, through the cooperation of the raised ring 23 and the card slot 24, it can be ensured that the eye mask 2 and the eyepiece 1 are not fixed and firmly connected. When the imaging product is picked up by the eye mask 2, the eye mask 2 and the eyepiece 1 are not easy to fall off, thereby reducing the risk of the imaging device falling off.

[0035] The observation part 21 is a retractable bellows, which enables the eye mask 2 to be retracted well, and can ensure that the human eye is at the exit pupil position of the eyepiece 1, so as to better view the image.

[0036] Example 2

[0037] The difference between this embodiment and the first embodiment is that there are multiple blank areas 112 outside the hand wheel 11 , and the specific number may be 2, 3 or 4, and the blank areas 112 may be evenly distributed outside the hand wheel 11 .

[0038] Example 3

[0039] The difference between this embodiment and embodiment 1 is that the raised ring 23 is a discontinuous ring structure composed of a plurality of arc-shaped protrusions, the arc-shaped protrusions are evenly distributed along the circumference of the connecting portion 22, and the arc-shaped protrusions are clamped in the clamping grooves 24 to ensure the clamping strength between the connecting portion 22 and the hand wheel 11.

[0040] In addition to the above-mentioned eyepiece eye mask, the present invention also provides an imaging device including the eyepiece eye mask disclosed in the above-mentioned embodiment. For the structures of other parts of the imaging device, please refer to the prior art and will not be described in detail herein.

[0041] Since the imaging device adopts the eyepiece eye mask disclosed in any one of the above embodiments, it has the same beneficial effects as the above eyepiece eye mask, which will not be repeated here.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
