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.
[0030] Furthermore, 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.

[0031] This application provides a lens mounting base that can be applied to optical paths, such as laser optical paths, for mounting optical lenses. The lens mounting base can be used to mount optical lenses such as lenses or mirrors.
[0032] See Figure 1 and Figure 2 A lens mounting base includes a base 100 and a mounting body 200. The mounting body 200 is used to mount an optical lens 800. The base 100 and the mounting body 200 are connected by a first connector 300a. The first connector 300a allows a first opening 400a to be formed between the base 100 and the mounting body 200. The first opening 400a has two opposing first adjustment spaces. A first lifting member (not shown in the figure) is provided on the base 100 located at the first opening 400a. The first lifting member can rise relative to the base 100 to abut against the mounting body 200, so as to drive the mounting body 200 to shift from one first adjustment space to the other first adjustment space.
[0033] It should be noted that the first opening 400a can specifically refer to a groove or through hole with an opening formed between the edge of the base 100 and the edge of the mounting body 200.
[0034] Specifically, the lens mounting base can be adjusted by a first lifting member disposed on the base 100 and located in the first opening 400a, so that the first lifting member can abut against the mounting body 200 and drive the mounting body 200 to shift from one first adjustment space to another first adjustment space.
[0035] It is understandable that when the mounting body 200 is angularly offset relative to the base 100, the first connecting body 300a may undergo corresponding deformation. In addition, the offset angle between the mounting body 200 and the base 100 is generally small, so the amount of deformation of the first connecting body 300a is generally small, and therefore, it generally will not cause the first connecting body 300a to break.
[0036] In other words, in the lens mounting base of this application, the base 100 and the mounting body 200 are connected by a first connector 300a, and the first connector 300a forms a first opening 400a between the base 100 and the mounting body 200. The first opening 400a has two first adjustment spaces arranged opposite to each other. A first lifting member is provided on the base 100 at the first opening 400a. The first lifting member can rise to abut against the mounting body 200, so as to drive the mounting body 200 to shift from one first adjustment space to another first adjustment space, thereby realizing the angular shift of the mounting body 200 relative to the base 100, that is, realizing the adjustment of the angle of the optical lens 800 mounted on the mounting body 200. The adjustment method is simple and convenient.
[0037] For example, in some embodiments, the first connector 300a can be connected to the area near the middle of the base 100 and the mounting body 200 respectively, so that an annular first opening 400a is formed between the base 100 and the mounting body 200. This allows the mounting body 200 to be tilted toward another first adjustment space after the first lifting member is set from a first adjustment space of the first opening 400a to lift the mounting body 200, that is, the angle of the mounting body 200 can be adjusted.
[0038] See Figure 1 In other embodiments, the first connector 300a may also form two first adjustment spaces with first openings 400a on opposite sides between the seat 100 and the mounting body 200, and a first lifting member is provided on the seat 100 located in at least one of the first adjustment spaces.
[0039] It is understandable that since the first opening 400a is located on opposite sides between the base 100 and the mounting body 200, when the mounting body 200 is lifted by the first lifting member located in the first adjustment space on one side, the mounting body 200 can tilt towards the first adjustment space on the other side to achieve angle adjustment.
[0040] Furthermore, the first openings 400a that are arranged opposite to each other are interconnected. It can be understood that after the first openings 400a that are arranged opposite to each other are interconnected, when the mounting body 200 is angularly offset relative to the base 100, the obstruction of the first connecting part to the movement of the mounting body 200 can be reduced, and the first lifting member can easily lift and adjust the mounting body 200.
[0041] For example, two first connectors 300a may be provided between the mounting body 200 and the base 100. The two first connectors 300a are respectively disposed opposite to each other between the base 100 and the mounting body 200. The interval between the two first connectors 300a can allow the two oppositely disposed first openings 400a to communicate.
[0042] Preferably, in order to ensure the stability of the connection between the mounting body 200 and the base 100 through the first connector 300a, the first connector 300a can be connected to the base 100 near the edge of the mounting body 200.
[0043] Furthermore, the first opening 400a may extend along the circumferential direction of the mounting body 200 so that a sufficiently large first opening 400a can be formed between the seat 100 and the mounting body 200 to facilitate the angular offset of the mounting body 200 relative to the seat 100.
[0044] See Figure 1 In some embodiments, to facilitate multi-angle adjustment of the mounting body 200, the lens mounting base may also include an adapter 500, which is disposed between the base 100 and the mounting body 200.
[0045] The adapter 500 and the mounting body 200 are connected by a first connector 300a. The first connector 300a creates two opposing first adjustment spaces with a first opening 400a between the adapter 500 and the mounting body 200 along a first direction. A first lifting member is provided on the adapter 500 located in the first adjustment space.
[0046] The adapter 500 and the base 100 are connected by a second connector 300b. The second connector 300b creates two opposing second adjustment spaces with a second opening 400b between the adapter 500 and the base 100 along a second direction. A second lifting member is provided on the base 100 located in the second adjustment space. The second lifting member can approach and abut against the adapter 500 to drive the adapter 500 to shift from one second adjustment space to another. The second direction is perpendicular to the first direction.
[0047] It is understandable that, since the first adjustment space is set relative to the first direction, the first lifting member lifts the mounting body 200, and the mounting body 200 can tilt relative to the seat 100 in the plane of the first direction, thereby realizing the adjustment of the angle offset of the mounting body 200 in the plane of the first direction.
[0048] Since the second adjustment space is arranged relative to the second direction, when the second lifting member lifts the adapter 500, the adapter 500 can tilt relative to the base 100 in the plane in the second direction. Since the adapter 500 is connected to the mounting body 200 through the first connector 300a, the mounting body 200 can tilt in the second direction with the adapter, thereby realizing the adjustment of the angle offset of the mounting body 200 in the plane in the second direction.
[0049] Furthermore, the two relatively arranged adjustment spaces are interconnected. It can be understood that after the two relatively arranged adjustment spaces are interconnected, when the adapter 500 is angularly offset relative to the base 100, the obstruction of the second connecting part to the movement of the adapter 500 can be reduced, making it easier for the second lifting member to lift and adjust the adapter 500.
[0050] For example, two second connectors 300b can be provided between the adapter 500 and the base 100. The two second connectors 300b are respectively arranged opposite to each other between the adapter 500 and the base 100, and the interval between the two second connectors 300b can connect the two oppositely arranged second adjustment spaces.
[0051] Preferably, in order to ensure the stability of the connection between the adapter 500 and the base 100 through the second connector 300b, the second connector 300b can be connected to the base 100 near the edge of the adapter 500.
[0052] Furthermore, the second opening 400b may extend along the circumferential direction of the adapter 500 so that a sufficiently large second opening 400b can be formed between the base 100 and the adapter 500 to facilitate the angular offset of the adapter 500 relative to the base 100.
[0053] In addition, in some embodiments, in order to facilitate the connection of the first connector 300a to the mounting body 200 and the adapter 500 respectively, and to facilitate the connection of the second connector 300b to the adapter 500 and the base 100 respectively, the mounting body 200, the first connector 300a, the adapter 500, the second connector 300b and the base 100 can be integrally formed.
[0054] See Figure 1 When the first lifting member lifts the mounting body 200, in order to ensure that the mounting body 200 can be accurately offset on the plane of the first direction, and when the second lifting member lifts the adapter body 500, in order to ensure that the adapter body 500 can be accurately offset at an angle on the plane of the second direction, the relatively set first adjustment space can be symmetrical about the first connecting body 300a as the axis of symmetry, and the relatively set second adjustment space can be symmetrical about the second connecting body 300b as the axis of symmetry.
[0055] Furthermore, the first lifting member can abut against the middle position of the mounting body 200 located in the first adjustment space to ensure that when the first lifting member applies force to the mounting body 200, the mounting body 200 can be accurately offset in the plane of the first direction.
[0056] The second lifting member can abut against the middle position of the adapter 500 located in the second adjustment space to ensure that when the second lifting member applies force to the adapter 500, the mounting body 200 can be accurately offset on the plane of the second direction.
[0057] See Figure 2 A first lifting hole 600a may be provided at the end of the base 100 away from the adapter 500. The first lifting hole 600a is connected to the first opening 400a via the second connector 300b and the adapter 500. A first lifting member is threadedly connected to the first lifting hole 600a. The first lifting member may be a kimming screw, and the first lifting hole 600a may be a threaded hole.
[0058] It is understandable that the first lifting hole 600a, in conjunction with the first lifting member, facilitates the adjustment of the first lifting member, enabling it to lift the mounting body 200 by a predetermined angle. Furthermore, the first lifting hole 600a connects to the first opening 400a via the second connector 300b and the adapter 500, facilitating the installation and adjustment of the first lifting member.
[0059] A second lifting hole 600b may be provided at the end of the base 100 away from the adapter 500. The second lifting hole 600b connects to the second opening 400b, and the second lifting hole 600b corresponds to the area on the adapter 500 where the first connector 300a is connected. The second lifting member is threadedly connected to the second lifting hole 600b. The second lifting member may be a ferrule, and the second lifting hole 600b may be a threaded hole.
[0060] Since the second lifting hole 600b corresponds to the area on the adapter 500 where the first connector 300a is connected, the second lifting member located within the second lifting hole 600b can abut against the area on the adapter 500 where the first connector 300a is connected and cause the adapter 500 to shift. This ensures that the adapter 500 can shift the mounting body 200 via the first connector 300a. It is understood that because the first opening 400a is provided between the adapter 500 and the mounting body 200, if the second lifting member abuts against the adapter 500 corresponding to the first opening 400a, the first opening 400a may cause deformation of the adapter 500, thus affecting the adjustment accuracy.
[0061] In addition, to prevent the mounting body 200 from being scratched and damaged by the first lifting member, and to prevent the adapter body 500 from being scratched and damaged by the second lifting member, a first gasket 700a may be provided on the mounting body 200 corresponding to the area supported by the first lifting member, and a second gasket 700b may be provided on the adapter body 500 corresponding to the area supported by the second lifting member.
[0062] Specifically, the first lifting member can move the mounting body 200 by abutting against the first gasket 700a, and the second lifting member can move the adapter body 500 by abutting against the second gasket 700b.
[0063] See Figure 1 and Figure 2 This application also provides an optical mechanism, including an optical lens 800 and a lens mounting base in the embodiments of this application. The optical lens 800 is disposed on the mounting body 200. The optical lens 800 is a reflector or a lens. When the optical lens 800 is a lens, the area of the base 100 and the mounting body 200 corresponding to the lens is provided with a light-transmitting hole.
[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
