Description

Technical Field

[0001] The utility model relates to the technical field of optical elements, in particular to an adapter ring structure and an optical aiming device for realizing rapid disassembly and assembly of infrared front-end products. Background Art

[0002] At present, the white light sight on the market can only be used for aiming during the day and cannot be used at night. However, an infrared front mirror can be added to the front of the white light sight to expand the night vision function of the white light sight. The white light sight obtains an infrared image through the display screen in the infrared front mirror for aiming. Therefore, the connection between the white light sight and the infrared front mirror requires a specific adapter to ensure that the two can be firmly connected to ensure the stability of the image display.

[0003] In the outdoor field, white light sights are widely used. They can clearly see the detailed features of the target, but their usage time is limited to scenarios with good light during the day. Their use is limited in conditions such as night, fog, haze, or through vegetation. However, an infrared thermal imaging component can be added to the front end of the white light sight. The fusion of infrared and visible light can achieve all-weather target recognition and detection, allowing the white light sight to be used normally at night, in fog, haze, or through vegetation.

[0004] The current infrared front-end products use a threaded structure to spirally connect the infrared thermal imaging component to the white light sight. In order to ensure a stable connection between the two, it must be rotated at least 10 times before it can be installed in place. This method of installing the infrared thermal imaging component to the white light sight takes too long, affecting the user's actual experience.

[0005] Therefore, how to reduce the installation time of infrared front-end products is a technical problem that technicians in this field need to solve. Utility Model Content

When the locking ring slider slides into the body slide, the anti-falling screw is inserted into the anti-falling screw hole and extends into the body mounting interface.

[0014] As a further improvement of the above technical solution:

[0015] A plurality of body stoppers are provided at one end of the adapter ring body close to the locking ring, and the body stoppers are used to limit the rotation of the components to be connected through the locking ring.

For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. Technical personnel in the field can understand their specific meanings in this application according to the specific circumstances.

[0036] like Figures 1 to 3As shown, an adapter ring structure provided by an embodiment of the present application includes a hollow adapter ring body 1 and a locking ring 2, wherein the locking ring 2 is rotatably connected to the adapter ring body 1, a through hole 25 is provided in the locking ring 2, and a plurality of locking ring pressure pieces 23 extending inward from the edge of the through hole 25 are provided at the end away from the adapter ring body 1, and a whole machine installation port 21 is formed between two adjacent locking ring pressure pieces 23, and the whole machine installation port 21 is used to match with the buckling part of the component to be connected, and the locking ring 2 can be rotated between a connection state in which the locking ring pressure piece 23 is opposite to the buckling part, and a quick release state in which the whole machine installation port 21 is opposite to the buckling part.

[0037] Among them, the hollow part of the adapter ring body 1 is used to connect the daylight sight, and the hollow part of the locking ring 2 is used to connect the component to be connected. The component to be connected in this embodiment is specifically an infrared thermal imager. Four eyepiece barrel buckles 91 are provided on the eyepiece barrel 9 of the infrared thermal imager. In other embodiments, any number of eyepiece barrel buckles 91 can be provided on the eyepiece barrel 9 according to actual needs. The shape of the whole machine mounting port 21 of the locking ring 2 is adapted to the shape of the eyepiece barrel buckle 91, so that the eyepiece barrel 9 of the infrared thermal imager can be inserted through the through hole 25 and the whole machine mounting port 21. In this embodiment, there are also four locking ring pressing pieces 23, thereby forming four whole machine mounting ports 21. After the eyepiece barrel 9 of the infrared thermal imager is inserted, the locking ring 2 is rotated to make the locking ring pressure piece 23 of the locking ring 2 face the eyepiece barrel buckle 91. The contact surface between the locking ring pressure piece 23 and the eyepiece barrel buckle 91 is an inclined surface. When the locking ring 2 rotates, the distance between the locking ring pressure piece 23 and the eyepiece barrel buckle 91 is gradually reduced. Finally, when the locking ring pressure piece 23 faces the eyepiece barrel buckle 91, the locking ring pressure piece 23 is tightly against the eyepiece barrel buckle 91. Therefore, after the eyepiece barrel 9 of the infrared thermal imager is inserted into the locking ring 2, the locking ring 2 only needs to be rotated 1 / 4 turn to install the infrared thermal imager on the adapter ring structure. Compared with the current rotation connection method, the installation time of the infrared thermal imager is greatly reduced.

[0038] Optionally, the locking ring 2 further includes a plurality of locking ring sliders 22 arranged on the inner side, and a locking ring wrench 24 arranged on the outer side for driving the locking ring 2 to rotate.

[0039] Specifically, in the present embodiment, the number of locking ring sliders 22 on the inner side of the locking ring 2 is specifically 4. In other embodiments, the number of locking ring sliders 22 can also be set to any number according to actual needs. The locking ring wrench 24 is a part of the cylindrical locking ring 2 protruding outward, so as to facilitate the user to turn the locking ring 2 to rotate.

[0040] Optionally, a body slide 11 corresponding to the locking ring slider 22 is provided on the adapter ring body 1. The body slide 11 is an elongated hole extending in the radial direction. One end of the body slide 11 is provided with an end surface passing through the adapter ring body 1 for the locking ring slider 22 to slide into a body mounting interface 12 in the corresponding body slide 11.

[0041] Among them, in this embodiment, the elongated hole can be a through hole that radially penetrates the adapter ring body 1, or it can be a blind hole that does not penetrate the adapter ring body 1. The elongated hole in this embodiment is specifically a blind hole that does not penetrate the adapter ring body 1. At one end of the body slide 11, the body mounting interface 12 is formed after penetrating the adapter ring body 1 along the axial direction of the adapter ring body 1. The shape of the body mounting interface 12 is adapted to the locking ring slider 22 on the inner side of the locking ring 2, so that the locking ring slider 22 can slide into the body slide 11 through the body mounting interface 12. When the four locking ring sliders 22 on the inner side of the locking ring 2 all slide into the body slide 11 of the adapter ring body 1, the locking ring 2 is connected to the adapter ring body 1. Since the body slide 11 has a certain length, the locking ring 2 can rotate in the adapter ring body 1.

[0042] Optionally, along the axial direction of the adapter ring body 1, the bottom of the body mounting interface 12 is provided with an anti-falling screw hole 14 connected to the body mounting interface 12, and when the locking ring slider 22 slides into the body slide 11, the anti-falling screw 7 is inserted into the anti-falling screw hole 14 and extends into the body mounting interface 12.

[0043] In order to prevent the locking ring slider 22 from rotating to the main body mounting interface 12 during the rotation, thereby causing the locking ring 2 to separate from the adapter ring body 1, the present embodiment also provides an anti-falling screw hole 14 that penetrates the adapter ring body 1 at the bottom of the main body mounting interface 12. When the locking ring slider 22 slides into the main body slide 11, the anti-falling screw 7 is inserted into the anti-falling screw hole 14 and extends the anti-falling screw 7 to the main body mounting interface 12, thereby limiting the locking ring slider 22 and preventing the locking ring slider 22 from sliding to the main body mounting interface 12 and causing the locking ring 2 to separate from the adapter ring body 1.

[0044] Optionally, a plurality of body stops 13 are provided at one end of the adapter ring body 1 close to the locking ring 2 , and the body stops 13 are used to limit the rotation of the components to be connected through the locking ring 2 .

[0045] Specifically, the number of the main body blocks 13 is 4. When the connecting ring structure of this embodiment is ready to install the infrared thermal imager, the main body block 13 is opposite to the locking ring pressure piece 23. When the eyepiece barrel 9 for installing the infrared thermal imager is inserted into the locking ring 2, the two sides of the eyepiece barrel buckle 91 on the eyepiece barrel 9 will be limited by the main body block 13. When the locking ring 2 is rotated, the infrared thermal imager can be prevented from rotating together due to the influence of friction.

[0046] Optionally, the side wall of the adapter ring body 1 is provided with an opening extending in the axial direction and bosses located on both sides of the opening, and the adjusting screw 5 is connected to the boss. The adjusting screw 5 includes a screw rod passing through the boss, a locking insert 3 connected to the end of the screw rod away from the nut, and a locking knob 4. The locking knob 4 drives the locking insert 3 to rotate to adjust the size of the opening, thereby adjusting the radial dimension.

[0047] In order to make the adapter ring body 1 adapt to day-light sights of different diameters, an opening is provided on the side wall of the adapter ring body 1 of the present embodiment, and the opening extends along the axial direction of the adapter ring body 1 and penetrates the entire adapter ring body 1 in the radial direction of the adapter ring body 1. Bosses are provided on both sides of the opening, and the adjusting screw 5 connects the two bosses. The adapter ring body 1 can adjust the size of the opening by adjusting the screw 5, and then adjust the radial size. Specifically, the locking knob 4 is a device similar to a wrench, and the locking insert 3 is driven to rotate by the locking knob 4. The locking insert 3 is equivalent to a nut. When the locking insert 3 rotates, the distance between the locking insert 3 and the nut will be changed. When the locking insert 3 and the nut respectively contact the two bosses, further rotating the locking insert 3 can shorten the distance between the two bosses, thereby reducing the opening size and adjusting the radial size of the adapter ring body 1.

[0048] In other preferred embodiments of the present invention, the locking insert 3 and the locking knob 4 are no longer required. One of the two bosses is a threaded boss with a threaded through hole, and the other boss is an ordinary boss without a threaded through hole. The adjusting screw 5 first passes through the ordinary boss and then enters the threaded boss. When the nut of the adjusting screw 5 contacts the ordinary boss, further rotating the adjusting screw 5 can shorten the distance between the two bosses, thereby reducing the opening size. The principle of increasing the opening is the same as that of reducing it, so it is not repeated here. In this way, the radial size of the adapter ring body 1 is adjusted. Compared with the method of adjusting the opening size by using the locking insert 3 and the locking knob 4, the structure of this embodiment is simpler.

[0049] Optionally, the adapter ring body 1 is further provided with a body annular groove 15 for accommodating the rubber ring 8 , and when the locking ring 2 is installed on the adapter ring body 1 , the rubber ring 8 forms an interference fit with the adapter ring body 1 .

[0050] Specifically, the main body annular groove 15 in this embodiment is used to place the rubber ring 8. The cross-section of the main body annular groove 15 is semicircular. When the rubber ring 8 is placed in the main body annular groove 15, half of the rubber ring 8 will be exposed outside the main body annular groove 15. When the locking ring 2 is installed on the adapter ring body 1, the inner side surface of the locking ring 2 will be tightly against the rubber ring 8 and form an interference fit, which can enhance the rotation feel when the locking ring 2 rotates, thereby improving the user experience.

[0051] Optionally, an inner lining ring 6 for connecting another component to be connected is also provided in the adapter ring body 1.

[0052] Specifically, the other component to be connected in the present embodiment is a day light sight. The diameter and thickness of the inner lining ring 6 are selected according to the day light sight. After the inner lining ring 6 is arranged inside the adapter ring body 1, the locking insert 3 is driven to rotate by the locking knob 4 to reduce the opening, so that the inner lining ring 6 is fastened inside the adapter ring body 1.

[0053] The adapter ring structure of the present embodiment directly inserts the white light sight into the inner lining ring 6, and the eyepiece barrel 9 of the infrared thermal imager and the eyepiece barrel buckle 91 on the eyepiece barrel 9 are inserted into the through hole 25 of the locking ring 2 of the connecting ring structure and the whole machine installation port 21. After the eyepiece barrel 9 contacts the adapter ring body 1, it stops, and then the locking ring 2 is rotated 1 / 4 turn to make the locking ring 2 face and abut against the eyepiece barrel buckle 91, thereby connecting the infrared thermal imager and the white light sight together. Compared with the current threaded connection method, the connection through the connecting ring structure of the present embodiment can greatly reduce the installation time of the infrared thermal imager and improve the user experience.

[0054] like Figure 3 As shown, on the other hand, the present application further provides an optical aiming device, including a white light aiming component, an infrared thermal imaging component and the adapter ring structure described in any embodiment of the present application, the white light aiming component is connected to the inner lining ring 6 in the adapter ring body 1, the outer periphery of the eyepiece barrel 9 of the infrared thermal imaging component is provided with an eyepiece barrel buckle 91 matching the whole machine mounting port 21, and the infrared thermal imaging component is connected to the locking ring 2.

[0055] Compared with the current method of connecting the infrared thermal imager and the white light sight together by threaded connection, the optical aiming device of this embodiment only needs to rotate the tightening ring 2 by 1 / 4 circle to fix the infrared thermal imaging component, which greatly reduces the installation time of the infrared thermal imager and improves the user experience.

[0056] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
