Detailed Implementation

[0030] Optical aiming devices are among the most widely used optical components in firearms and other instruments. A significant characteristic of firearms, artillery, aircraft, and ships is that they generate extremely strong recoil during actual use. This causes a strong impact on the various components of the optical aiming device. This impact can not only cause deviations in the optical path between the optical elements in the optical aiming device, but also cause damage to the optical elements to a certain extent.

[0031] When optical aiming devices are used in equipment such as cameras and astronomical telescopes, although they do not generate strong impact in actual use, it is still impossible to completely avoid the problem of optical displacement caused by accidental collisions during the handling and assembly of the equipment.

[0032] Therefore, this application provides an intermediate buffer connection component and an optical aiming device including the intermediate buffer connection component, which can enhance the resistance to external impact or vibration during the combined use of different aiming scopes, thereby improving the optical performance and service life of the optical aiming device to a certain extent.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the optical aiming device provided in the embodiments of this application.

[0035] like Figure 1 As shown, the optical aiming device in this application includes an infrared front sight assembly 102 and a white light sight assembly 101, and the infrared front sight assembly 102 and the white light sight assembly 101 are detachably connected to each other by a quick-release adapter ring 103; on this basis, an intermediate buffer connection assembly 100 is further provided between the quick-release adapter ring 103 and the white light sight assembly 101, and the intermediate buffer connection assembly 100 can buffer the impact force between the infrared front sight assembly 102 and the white light sight assembly 101 to a certain extent.

[0036] like Figures 2 to 4 As shown, Figure 2 A cross-sectional structural schematic diagram of an intermediate buffer connection assembly provided in an embodiment of this application; Figure 3 An exploded view of the intermediate buffer connection assembly provided in the embodiments of this application; Figure 4 This is a schematic diagram of another cross-sectional structure of the intermediate buffer connection component provided in an embodiment of this application.

[0037] In one specific embodiment of this application, the intermediate buffer connection assembly 100 is used to connect the first sight assembly and the second sight assembly in the optical aiming device; the intermediate buffer connection assembly 100 may specifically include a first cylindrical connector 11, a second cylindrical connector 12 and a pressure buffer 13;

[0038] The first cylindrical connector 11 and the second cylindrical connector 12 are nested together; a pressure buffer 13 is provided between two surfaces perpendicular to the axial direction of the surfaces of the first cylindrical connector 11 and the second cylindrical connector 12 that are in contact with each other; the central axes of the first cylindrical connector 11 and the second cylindrical connector 12 are collinear; and the axial direction is parallel to the central axis.

[0039] It is understood that the intermediate buffer connection component 100 in this embodiment is a connector for connecting the first sight assembly and the second sight assembly in the optical aiming device. The first sight assembly can be an infrared front sight assembly 102, and the second sight assembly can be a white light sight assembly 101.

[0040] Based on this, the intermediate buffer connection assembly 100 of this embodiment includes a first cylindrical connector 11 and a second cylindrical connector 12. The first cylindrical connector 11 and the second cylindrical connector 12 generally adopt a cylindrical structure, and should at least be a centrally symmetrical cylindrical structure. Furthermore, the central symmetry axes of the first cylindrical connector 11 and the second cylindrical connector 12 should coincide and be collinear.

[0041] Furthermore, in this embodiment, the first cylindrical connector 11 and the second cylindrical connector 12 are also connected sequentially along their collinear central axis of symmetry. When the optical aiming device is applied to firearms or other instruments and is subjected to significant impact during use, the mutual impact force between the first cylindrical connector 11 and the second cylindrical connector 12 is mainly along their collinear central axis. Therefore, in this embodiment, a pressure buffer 13 is provided between the surfaces of the first cylindrical connector 11 and the second cylindrical connector 12 that are in contact with each other, especially between the surfaces of the first cylindrical connector 11 and the second cylindrical connector 12 that are in contact with each other and perpendicular to the axial direction. Obviously, the pressure buffer 13 can effectively buffer the impact force between the first cylindrical connector 11 and the second cylindrical connector 12 along the axial direction. Based on the rigid connection between the first cylindrical connector 11 and the second cylindrical connector 12 and the first and second scope assemblies respectively, the pressure buffer 13 can buffer the impact force on the connection structure between the first and second scope assemblies, thereby avoiding the problem of optical deviation between the first and second scope assemblies due to external impact force.

[0042] Based on the above discussion, this application uses an intermediate buffer connection component 100 to connect two different sights in an optical aiming device. Compared to the conventional optical aiming device where all optical components are rigidly connected, the intermediate buffer connection component 100 in this application can effectively buffer the strong impact force (such as the strong recoil generated by gun firing) that the optical aiming device is subjected to during use. In other words, it buffers the mutual impact force between the first sight component and the second sight component to a certain extent, which helps to ensure the optical performance of the optical aiming device in practical applications and extend the service life of the optical aiming device.

[0043] Based on the above embodiments, in an optional embodiment of this application, the intermediate buffer connection component 100 may specifically include:

[0044] The first cylindrical connector 11 includes a first limiting member and a second limiting member that are connected to each other; the second cylindrical connector 12 includes a nested portion;

[0045] When the nested part is nested between the first limiting member and the second limiting member, the first limiting member and the second limiting member are respectively located on both sides of the nested part in the axial direction, so that the first limiting member restricts the nested part from moving in the axial direction, and the second limiting member restricts the nested part from moving in the opposite direction in the axial direction.

[0046] Pressure buffers 13 are provided between the first limiting member and the nested part, and between the second limiting member and the nested part.

[0047] In this embodiment, the first and second limiting members can be rigidly connected, or the distance between them in the axial direction should be fixed, thereby forming a space in the axial direction to accommodate the nested portion. The size of this space in the axial direction is equivalent to, or slightly larger than, the size of the nested portion in the axial direction of the second cylindrical connector 12. The pressure buffer 13 further fills the gaps between the first and second limiting members and the nested portion, thereby allowing the first and second limiting members, together with the pressure buffer 13, to buffer and limit the nested portion in the axial direction. Furthermore, the nested portion is part of the second cylindrical connector 12, and buffering and limiting the nested portion is also buffering and limiting the second cylindrical connector 12. That is to say, the first cylindrical connector 11 and the second cylindrical connector 12 are not directly rigidly connected, but are nestedly connected in the axial direction through buffering and limiting.

[0048] Therefore, the connection method of the first cylindrical connector 11 and the second cylindrical connector 12 in this application can effectively avoid stress concentration, loosening, stripping, jamming and other problems in the rigid threaded connection part compared with the rigid connection method between the components in the conventional optical sight device, thereby improving the impact resistance of the optical sight device to shooting impact force.

[0049] It is understood that the first and second limiting members in this application can have various different configurations; such as Figure 2 and Figure 3 As shown, in an optional embodiment of this application, the intermediate buffer connection component 100 may specifically include:

[0050] The first limiting member is an annular groove 111 with a U-shaped cross section; the second limiting member is an annular pressure cap 112 with an L-shaped cross section.

[0051] The second cylindrical connector 12 includes an integrally formed first annular cylinder 121, an annular plate 123, and a second annular cylinder 122; wherein the inner diameter of the first annular cylinder 121 is the same as the inner diameter of the annular plate 123, and the outer diameter of the second annular cylinder 122 is the same as the outer diameter of the annular plate 123, and the first annular cylinder 121, the annular plate 123, and the second annular cylinder 122 together form an annular stepped structure.

[0052] The second annular cylinder 122 is inserted into the annular groove 111; the annular cover 112 is attached to the surface of the annular plate 123 away from the annular groove 111 and the outer side of the annular groove 111; and the annular cover 112 and the outer annular wall of the annular groove 111 are detachably connected.

[0053] The pressure buffer 13 includes a first pressure buffer 131 and a second pressure buffer 132;

[0054] The first pressure buffer 131 is disposed between the annular cover 112 and the annular plate 123; the second pressure buffer 132 is disposed between the bottom of the annular groove 111 and the end face of the second annular cylinder 122.

[0055] exist Figure 2 and Figure 3 In the illustrated embodiment, the annular groove 111 with a U-shaped cross-section and the annular cap 112 with an L-shaped cross-section are respectively equivalent to the first limiting member and the second limiting member in the above embodiment; based on this, the structure formed by the annular plate 123 and the second annular cylinder 122 in the second cylindrical connector 12 is also equivalent to the nesting part in the above embodiment; at the same time, the first annular cylinder 121, the annular plate 123, and the second annular cylinder 122 are integrally formed to form the second cylindrical connector 12, wherein the first annular cylinder 121 is used to connect with a sight assembly in an optical aiming device, for example, by means of... Figure 1 The quick-release connector shown is detachably connected to the infrared front sight assembly 102.

[0056] Obviously, the first annular cylinder 121, the annular plate 123, and the second annular cylinder 122 can together form an annular cylindrical structure with a stepped cross-section. The first cylindrical connector (11) is composed of an annular groove 111 and an annular cap 112 that are rigidly connected to each other.

[0057] It is understood that the annular groove 111 and the annular cap 112 should be detachably connected to ensure that the second annular cylinder 122 can be placed inside the annular groove 11. Optionally, the outer wall of the annular groove 111 and the corner of the annular cap 112 can be fixedly connected by a nut; alternatively, the outer surface of the annular groove 111 and the surface of the annular cap 112 that fits against the outer wall of the annular groove 111 can be provided with mutually mating threads, so that the annular groove 111 and the annular cap 112 can be connected by threads.

[0058] Obviously, a rigid connection between the annular groove 111 and the annular cap 112 can form an L-shaped annular receiving space, which is used to accommodate the annular structure formed by the annular plate 123 and the second annular cylinder 122. In practical applications, the second annular cylinder 122 in the second cylindrical structure can be inserted into the annular groove 111 first, and then the annular cap 112 can be pressed onto the L-shaped outer surface formed by the surface of the annular plate 123 facing away from the annular groove 111 and the outer surface of the annular groove 111. The outer wall of the annular cap 112 and the annular groove 111 can be fixedly connected. In this way, the annular plate 123 and the second annular cylinder 122 in the second cylindrical connector 12 can be confined in the space between the annular cap 112 and the annular groove 111, which also realizes the non-rigid connection of the first cylindrical connector 11 and the second cylindrical connector 12 nested together.

[0059] Obviously, in this embodiment, the annular cap 112 can restrict the movement of the second cylindrical connector 12 in the opposite direction of the axial direction, while the annular groove 111 can restrict the movement of the second cylindrical connector 12 along the axial direction. Therefore, the pressure buffer 13 in this embodiment can further include a first pressure buffer 131 disposed between the annular cap 112 and the annular plate 123, and a second pressure buffer 132 disposed at the bottom of the annular groove 111.

[0060] It is understood that in this embodiment, the width of the annular groove 111 in the radial direction should be approximately the same as the thickness of the second annular cylinder 122 in the radial direction, which can limit the mutual offset between the second annular cylinder 122 and the annular groove 111 in the radial direction. In addition, although the impact force between the first cylindrical connector 11 and the second cylindrical connector 12 in the radial direction is relatively small in general, it cannot be completely eliminated. Therefore, in an optional embodiment of this application, elastic rubber membranes distributed in a circumferential direction are provided between the inner and outer annular sides of the second annular cylinder (122) and the two sides of the annular groove (111) respectively.

[0061] Specifically, annular elastic rubber membranes can be bonded to the groove walls on both sides of the annular groove 111. On the one hand, this can increase the friction between the inner and outer sides of the second annular cylinder 122 and the groove wall of the annular groove 111, avoiding unnecessary relative sliding between the annular groove 111 and the second annular cylinder 122 in the circumferential direction. On the other hand, it can also buffer the impact force between the second annular cylinder 122 and the annular groove 111 in the radial direction.

[0062] In addition, the depth of the annular groove 111 in this embodiment should be approximately the same as the dimension of the second annular cylinder 122 along the axial direction, at least ensuring that there is a gap between the end of the inner annular wall of the annular groove 111 near the annular plate 123 and the annular plate 123 along the axial direction, so as to avoid the inner annular wall of the annular groove 111 directly abutting against the annular plate 123, thereby ensuring that there is space for relative buffering movement between the annular groove 111 and the second annular cylindrical connector 12 along the axial direction; and when the annular cap 112 and the annular groove 111 are connected by mutual connection When connected, the distance between the bottom surface of the annular cap 112 and the annular groove 111 should be slightly larger than the axial dimension of the structure formed by the annular plate 123 and the second annular cylinder 122. Thus, with the second pressure buffer 132 provided at the bottom of the annular groove 111 and the first pressure buffer 131 provided between the annular cap 112 and the annular plate 123, the nested part formed by the second annular cylinder 122 and the annular plate 123 can have a certain buffer movement space between the annular cap 112 and the annular groove 111.

[0063] As described above, the annular cap 112 is rigidly connected to the outer wall of the annular groove 111 by bolts or threads. Obviously, when the annular cap 112 is pressed onto the annular plate 123 and connected to the annular groove 111, the first pressure buffer 131 between the annular plate 123 and the annular cap 112 will inevitably be squeezed. Therefore, in this embodiment, the first pressure buffer 131 can be a metal elastic element capable of withstanding greater compressive force, while the second pressure buffer 132 can be a flexible buffer pad. Specifically, the first pressure buffer 131 can be a wave-shaped elastic element, a metal spring sheet, etc., while the second pressure buffer 132 can be a rubber pad or a high-hardness foam pad, etc.

[0064] In addition, to ensure the stability of the annular cap 112 pressed onto the annular plate 123, an annular stepped groove can be formed around the edge of the annular plate 123 near the annular cap 112, and the second pressure buffer 132 can be placed in the annular stepped groove.

[0065] Based on the above discussion, the annular groove 111 and the annular cap 112 are merely one specific implementation of forming the first and second limiting members in this application. This application does not exclude other methods of forming a structure capable of buffering and limiting the second cylindrical connector 12 in the axial direction. For example... Figure 4 As shown, in Figure 4 In the illustrated embodiment, the nesting portion of the second cylindrical connector 12 is an externally protruding ring 120 located at its end and protruding from the outer side of the second cylindrical connector 12. The first limiting member and the second limiting member are respectively an L-shaped limiting ring 113 and a stepped limiting ring 114 pressed onto both sides of the externally protruding ring 120, and the L-shaped limiting ring 113 and the stepped limiting ring 114 are also fixedly connected by bolts 115. The pressure buffer 13 is respectively disposed in the gaps between the externally protruding ring 120 and the L-shaped limiting ring 113 and the stepped limiting ring 114. Obviously, in Figure 4 In the embodiment shown, a buffer connection in which the first cylindrical connector 11 and the second cylindrical connector 12 are nested together can also be achieved.

[0066] In summary, the intermediate buffer connection assembly of this application, as a connection between the first and second scope assemblies, includes a first cylindrical connector and a second cylindrical connector that can be nested together and share a central axis. Furthermore, a pressure buffer is provided between the first and second cylindrical connectors. This pressure buffer is located between two surfaces of the first and second cylindrical connectors that are in contact with each other and perpendicular to the axial direction. This allows the first and second scope assemblies to buffer strong impact forces during practical applications, thereby preventing optical axis misalignment between the first and second scope assemblies to a certain extent, delaying impact damage between components, and extending the service life of the entire optical aiming device.

[0067] Based on any of the above embodiments, refer to Figure 1 This application also provides an embodiment of an optical aiming device, which includes a first aiming scope assembly and a second aiming scope assembly, as well as an intermediate buffer connection assembly 100 as described above; the two ends of the intermediate buffer connection assembly 100 are respectively connected to the first aiming scope assembly and the second aiming scope assembly.

[0068] Optionally, the first sight assembly in this embodiment can be Figure 1 The white light scope assembly 101 in the middle, while the second scope assembly can be Figure 1 The infrared front-facing aiming scope assembly 102 is shown in the figure. Of course, the first and second aiming scope assemblies in this embodiment may also be other types of aiming scopes, depending on the actual application requirements. This application does not impose any specific restrictions on this.

[0069] In addition, in this embodiment, the first sight assembly can be connected to the first cylindrical connector 11 via a quick-release assembly; the second sight assembly can be connected to the second cylindrical connector 12. The quick-release assembly can be as follows: Figure 1 The quick-release adapter ring 103 is shown.

[0070] The first cylindrical connector 11 may be equipped with a protruding structure that cooperates with the quick-release assembly, so as to facilitate quick disassembly and connection of the two, and thus allow the scope type to be changed at any time according to actual needs.
