[0035] As mentioned above, in order to solve the problem in the prior art that the front infrared imaging device needs to be installed on the sight by rotating several turns through the threaded structure before it can be installed into place, the present application provides a front infrared imaging device quick-release adapter device, which is used to quickly transfer the front infrared imaging device to the white light sight and quickly remove the front infrared imaging device from the white light sight. The front infrared imaging device quick-release adapter of the present application includes a quick-release ring and an adapter ring installed on the sight; the quick-release ring includes a clamping ring and a quick-release ring body, the clamping ring and the adapter ring are respectively threadedly connected to the two axial ends of the quick-release ring body; the quick-release ring body is provided with a fixed seat positioning hole seat at one end facing the clamping ring, the fixed seat positioning hole seat is in a shape matching the front device fixed seat of the front infrared imaging device; the clamping ring is provided with a fixed seat limiting portion for the front device fixed seat to pass through in the axial direction, the fixed seat limiting portion and the fixed seat positioning hole seat are arranged opposite to each other in the axial direction; the fixed seat limiting portion rotates axially relative to the quick-release ring body with the clamping ring, and selectively clamps the front device fixed seat between the fixed seat limiting portion and the fixed seat positioning hole seat. The front infrared imaging device quick-release adapter of the present application assembles the quick-release ring to the adapter ring, and is quickly combined with the front infrared imaging device, and can be disassembled and assembled by clamping the quick-release ring around the quick-release ring body and rotating it at a small angle.

[0036] See also Figure 1 The front infrared imaging device quick-release adapter of one embodiment of the present application is used to quickly transfer the front infrared imaging device 10 to a white light sight (not shown) and quickly remove the front infrared imaging device 10 from the white light sight. The front infrared imaging device quick-release adapter in this embodiment includes a quick-release ring 20 and an adapter ring 30. The adapter ring 30 is installed at the front end of the white light sight. One end of the quick-release ring 20 is connected to the adapter ring thread 31 (and the white light sight) of the adapter ring 30, and the other end is connected to the front device fixing seat 11 of the front infrared imaging device 10.

[0037] Please refer to Figure 2 and Figure 3 The quick-release ring 20 includes a locking ring 21, a pressing ring 22, a quick-release ring body 23 and a stop screw 24. The locking ring 21, the pressing ring 22 and the quick-release ring body 23 are all annular and coaxially arranged. The locking ring 21 and the pressing ring 22 are respectively installed at the axial ends of the quick-release ring body 23, and the stop screw 24 passes through the radial direction of the pressing ring 22 and extends into the side wall of the quick-release ring body 23.

[0038] The inner wall of the locking ring 21 is provided with a locking ring thread 211, which is used to be threadedly connected to one end of the quick release ring body 22 (the end connected to the adapter ring 30). A toggle arm 212 protrudes outward from one side of the locking ring 21. The toggle arm 212 is used to conveniently rotate the locking ring 21 axially from the outside.

[0039] The inner wall of the pressing ring 22 is successively provided with a pressing ring thread portion 221, a fixing seat limiting portion 222, and a guiding portion 223 along the axial direction. Among them, the pressing ring thread portion 221 is used for threaded connection with the other end of the quick-release ring body 23 (the end connected to the connecting front infrared imaging device 10); the fixing seat limiting portion 222 is used for the front device fixing seat 11 of the front infrared imaging device 10 to axially pass through at a certain angle, and can limit the front device fixing seat 11 at one end of the quick-release ring body 23.

[0040] The fixing seat limiting portion 222 is in a shape matching the front device fixing seat 11 of the front infrared imaging device 10, so that the front device fixing seat 11 can pass through the fixing seat limiting portion 222. As Figure 3 shown, the fixing seat limiting portion 222 includes first notches 2221 and first limiting plates 2222 that are alternately distributed around the axial direction. The shape of the first notch 221 is the same as the shape of the front device fixing seat 11, and the shape of the first limiting plate 2222 is the same as the shape of the vacant part between adjacent front device fixing seats 11. In the illustrated embodiment, 4 front device fixing seats 11 spaced from the end of the front infrared imaging device 10, correspondingly, 4 first notches 2221 and 4 first limiting plates 2222 are alternately and spacedly distributed, thereby forming a shape corresponding to the front device fixing seat 11.

[0041] The guiding portion 223 is arranged between the outer end face of the pressing ring 23 and the fixing seat limiting portion 222. The guiding portion 223 is a conical surface, and the diameter gradually decreases from the outside to the fixing seat limiting portion 222 along the axial direction. It is used for guiding and aligning the front device fixing seat 11 of the front infrared imaging device 10 after entering from the outside, and can align the front infrared imaging device 10 coaxially with the quick-release ring 20. The diameter of the outside of the guiding portion 223 is larger than the outer diameter of the front device fixing seat 11, and the diameter of the guiding portion 223 adjacent to the fixing seat limiting portion 222 is approximately equal to the outer diameter of the front device fixing seat 11.

[0042] A through-wall stop screw mounting hole 224 is also provided on the outer wall of the pressing ring 22. The stop screw mounting hole 224 is arranged radially, and a stop screw 24 is used for installation therein. The end of the stop screw 24 protrudes from the inner wall of the pressing ring 22 and extends into the quick-release ring body 23.

[0043] On the outer wall of the pressing ring 22, a pressing ring wrench 225 protrudes outward. The pressing ring wrench 225 is used to rotate the pressing ring 22 axially. On the outer wall of the pressing ring 22, a pressing ring auxiliary wrench 226 may also protrude outward. The pressing ring auxiliary wrench 226 and the pressing ring wrench 225 are circumferentially spaced apart. In the illustrated embodiment, the portion of the pressing ring wrench 225 protruding from the outer wall of the pressing ring 22 is longer than the portion of the pressing ring auxiliary wrench 226 protruding from the outer wall. The pressing ring wrench 225 can be used for the operation of slightly rotating the pressing ring 22 with a single finger, and the pressing ring auxiliary wrench 226 can be used together with the pressing ring wrench 225 for the operation of rotating the pressing ring at a large angle with multiple fingers.

[0044] Please refer to Figure 4 , one end of the quick-release ring body 23 where the locking ring 21 (adapter ring 30) is installed is provided with a first body thread 231. The external thread of the first body thread 231 is matched with the internal threads of the adapter ring thread 31 of the adapter ring 30 and the locking ring thread 211, so that the adapter ring 30 and the locking ring 21 are detachably threadedly connected to one end of the quick-release body 22. One end of the quick-release ring body 23 where the pressing ring 22 is installed is provided with a second body thread 232, and the second body thread 232 is used for threaded connection with the pressing ring thread portion 221 of the pressing ring 22.

[0045] A fixed seat positioning hole seat 233 is formed on the end face where the quick-release ring body 23 is connected to the pressing ring 22 (front infrared imaging device 10). The fixed seat positioning hole seat 233 is used to abut against the end of the front device fixed seat 11 of the front infrared imaging device 10 and limit the front device fixed seat 11 axially and circumferentially. The fixed seat positioning hole seat 233 has a shape matching that of the front device fixed seat 11 of the front infrared imaging device 10, so that the front device fixed seat 11 can pass through the fixed seat limiting portion 222 and fall into the fixed seat positioning hole seat 233.

[0046] Specifically, as Figure 4As shown in the figure, the fixing seat positioning hole seat 233 includes a second notch 2331, a second limiting plate 2332 and an abutting plate 2333. The second notch 2331 and the second limiting plate 2332 are alternately distributed around the axis. The shape of the second notch 2331 is the same as the shape of the front device fixing seat 11, and the shape of the second limiting plate 2332 is the same as the shape of the vacant part between adjacent front device fixing seats 11, so that the front device fixing seat 11 can be limited in the second notch 2331 and cannot rotate around the axis. The abutting plate 2333 is connected to the side of the second notch 2331 and the second limiting plate 2332 away from the fixing seat limiting part 222, and is used for abutting against the outer end face of the front device fixing seat 11, so that the front device fixing seat 11 cannot continue to enter the quick-release ring body 23 along the axis. In the illustrated embodiment, 4 front device fixing seats 11 are spaced apart from the end of the front infrared imaging device 10. Correspondingly, 4 second notches 2331 and 4 second limiting plates 2332 are alternately spaced apart, so as to form a shape corresponding to the front device fixing seat 11; the abutting plate 2333 is an annular plate, and its inner diameter is slightly smaller than the inner diameter of the front device fixing seat 11, and does not affect the optical path of the front infrared imaging device, that is, the abutting plate 2333 protrudes slightly inward along the radial direction compared with the first limiting plate 2222.

[0047] In the illustrated embodiment, the fixing seat limiting part 222 is designed to have a shape matching that of the front device fixing seat 11, so that the front device fixing seat 11 can just pass through it, that is, the first limiting plate 2222 has the same shape as the notch between adjacent front device fixing seats 11, and the size of the first limiting plate 2222 reaches the maximum. In this way, when the front device fixing seat 11 is pressed, the pressing area of the first limiting plate 2222 on the front device fixing seat 11 reaches the maximum, making the pressing more stable. In other embodiments, the fixing seat limiting part 222 can also appropriately reduce the size of the first limiting plate 2222 or reduce the number of the first limiting plates 2222, and can also achieve the purpose of allowing the front device fixing seat 11 to pass through and pressing the front device fixing seat 11.

[0048] The quick-release ring body 23 is provided with a stop screw limiting groove 234 on the cylinder wall where the second body thread 232 is provided. The stop screw limiting groove 234 is an arc-shaped groove around the axis. The stop screw limiting groove 234 is used to limit the stop screw 24 installed in the stop screw mounting hole 224 of the pressing ring 22. The rotation angle of the pressing ring 22 relative to the quick-release ring body 23 around the axis is limited by the end of the stop screw 24 extending into the stop screw limiting groove 234. The central angle corresponding to the stop screw limiting groove 234 is set as the rotation angle of the pressing ring 22 relative to the quick-release ring body 23 when the front infrared imaging device is quickly disassembled and assembled. Preferably, the central angle corresponding to the stop screw limiting groove 234 is set as the central angle corresponding to the adjacent front device fixing seats 11, so that quick disassembly and assembly can be achieved without rotating a large angle, and the operation is more convenient. In the illustrated embodiment, the central angle corresponding to the stop screw limiting groove 234 is 90°. That is, the included angle between the limiting groove starting position 2341 at one end of the stop screw limiting groove 234 and the limiting groove ending position (not marked) at the other end relative to the axis is 90°.

[0049] When the stop screw 24 is at the limiting groove starting position 2341 of the stop screw limiting groove 234, the second notch 2331 of the fixing seat positioning hole seat 233 is axially aligned with the first notch 2221 of the fixing seat limiting portion 222. Thus, the front device fixing seat 11 can axially pass through the fixing seat limiting portion 222 and then fall into the fixing seat positioning hole seat 233. When the stop screw 24 is at the limiting groove ending position of the moving screw limiting groove 234, the second notch 2331 of the fixing seat positioning hole seat 233 is axially aligned with the first limiting plate 2222 of the fixing seat limiting portion 222. Thus, the first limiting plate 2222 stops the front device fixing seat 11 from axially disengaging from the second notch 2331.

[0050] The assembly process of the above front infrared imaging device quick-release adapter is as follows:

[0051] The locking ring 21 is assembled and connected to one end of the quick-release ring body 23 through the thread fit of the locking ring thread 211 and the first body thread 231. The pressing ring 22 is assembled and connected to the other end of the quick-release ring body 23 through the thread fit of the second body thread 232 and the pressing ring thread portion 221.

[0052] As the pressing ring 22 rotates axially relative to the quick-release ring body 23, when the set screw installation hole 224 rotates to a proper position (the position within the set screw limiting groove 234), a set screw 24 is inserted into the set screw installation hole 224 so that the set screw 24 extends into the set screw limiting groove 234. After assembling the set screw 24, the movement range of the set screw 24 and the pressing ring 23 on which the set screw 24 is installed relative to the quick-release ring body 23 is restricted within the set screw limiting groove 234. Thus, the rotation stroke of the pressing ring 22 after assembly is always the central angle corresponding to the set screw limiting groove 234 (90° in the illustrated embodiment).

[0053] After the locking ring 21 is installed on the quick-release ring body 23, one end of the quick-release ring body 23 where the locking ring 21 is installed is in threaded engagement with the adapter ring thread 31 through the first body thread 231, and is connected to the adapter ring 30 (and the white light sight). After the quick-release ring 20 and the adapter ring 30 are assembled, the locking ring 21 is twisted in the reverse direction towards the end face of the adapter ring 30 until the locking ring 21 abuts against the end face at the adapter ring thread 31, so that the quick-release ring body 23 is fixed relative to the adapter ring 30 and cannot be twisted any further. Since the angle of the front infrared imaging device 10 relative to the white light sight is determined by the angle of the fixed seat positioning hole seat 233, thus, after the relative angle between the quick-release ring body 23 (fixed seat positioning hole seat 233) and the white light sight is adjusted by the thread, the current position can be locked by the locking ring 21.

[0054] After the above-mentioned quick-release adapter device for the front infrared imaging device is assembled, the quick disassembly and assembly process of the front infrared imaging device 10 and the white light sight is as follows:

[0055] When installing the front infrared imaging device 10 on the white light sight, the front infrared imaging device 10 is axially inserted into the quick-release ring body 23 from the other end, so that the front device fixed seat 11 passes through the fixed seat limiting part 222 and is placed in the fixed seat positioning hole seat 233. After turning the pressing ring wrench 225 and the pressing ring auxiliary wrench 226 to rotate the pressing ring 22, under the cooperation and limiting action of the set screw 24 and the set screw limiting groove 234, the set screw 24 turns from the starting position 2341 of the limiting groove to the ending position of the limiting groove in the set screw limiting groove 234. Since the pressing ring thread part 221 and the second body thread 232 are connected by threads, during the rotation process, the axial distance d (as Figure 6 shown in the figure, in the direction of the arrow) between the pressing surface of the fixed seat limiting part 222 (the end face facing the fixed seat positioning hole seat 233) and the abutting surface of the fixed seat positioning hole seat 233 (i.e., the end face of the abutting plate 2333 facing the fixed seat limiting part 222) gradually becomes shorter, so that the pressing ring 22 gradually presses the front device fixed seat 11, playing a role in quickly fixing the front infrared imaging device 10.

[0056] When removing the front infrared imaging device 10 from the daylight sight, after the clamping ring wrench 225 and the clamping ring auxiliary wrench 226 are turned in the opposite direction to rotate the clamping ring 22, the stop screw 24 is rotated from the stop screw limit groove 234 to the limit groove starting position 2341. During the rotation process, the axial distance d (as shown in FIG. 2 ) between the clamping surface of the fixing seat limit portion 222 and the abutting surface of the fixing seat positioning hole seat 233 is Figure 6 As shown in the figure, it gradually becomes longer in the opposite direction of the arrow, so that the clamping ring 22 gradually loosens the front device fixing seat 11, until it is rotated until the second notch 2331 of the fixing seat locating hole seat 233 is axially aligned with the first notch 2221 of the fixing seat limiting portion 222, so that the front device fixing seat 11 can axially pass through the fixing seat limiting portion 222 and then escape from the quick release ring 20, thereby playing the role of quickly removing the front infrared imaging device 10.

[0057] See also Figure 6 According to the above working principle, it can be understood that when the stop screw 24 is located at the starting position 2341 of the limiting groove, the axial distance d between the two opposite end faces of the fixing seat limiting portion 222 and the fixing seat positioning hole seat 233 is greater than the thickness of the front device fixing seat 11. In addition, the axial distance d is not greater than the sum of the thickness of the front device fixing seat 11 and 0.25 times the pitch of the second body thread 232, so as to ensure that the clamping ring 22 can press the front device fixing seat 11 in the fixing seat positioning hole seat 233 of the quick release ring body 23 during the rotation process relative to the quick release ring body 23.

[0058] To sum up, the front infrared imaging device quick-release adapter device of the present application provides a structure that can quickly install and disassemble the front infrared imaging device. Compared with the threaded structure in the prior art that requires several turns (about 10 turns) to install the front infrared imaging device in place, the front infrared imaging device quick-release adapter device of the present application only needs to rotate the clamping ring (such as 1 / 4 turn as shown in the figure) to complete the disassembly and assembly, which can improve the user experience and meet the user's needs for quick disassembly and assembly.

[0059] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0060] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims described above.
