Description

红点瞄准镜 技术领域
本申请属于瞄准镜技术领域，尤其涉及一种红点瞄准镜。
背景技术
目前，红点瞄准镜通常包括光源、反射镜、准直物镜和分光棱镜，其中，光源用于朝目方出射光线，光源出射的光线会先经反射镜转向至准直物镜，再通过准直物镜转换成平行光，最后再经过分光棱镜转向并射入人眼。基于此，由于光源出射的光线朝向目方，从物方将基本观察不到光源的亮点，从而可降低射手暴露的风险。
但是在瞄准近距离的目标时，由于目标的光并非是平行光，而是具有一定发散角度的发散光，人眼为了能够看清目标，会自动调节晶状体来使目标成像于视网膜，而光源出射的光线经过准直物镜转换后却是平行光，此时人眼的晶状体形状已改变，因此光源出射的光线将成像在视网膜前方，导致光源出射的光线的成像与目标的成像没有在视网膜上叠加，进而会产生视差，具体表现为晃动头部时，光源出射的光线的成像与目标成像的相对位置会发生改变，这样就会影响瞄准的精准度。

具体实施方式
为了使本申请所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在本申请的描述中，需要理解的是，术语“长度”、“宽度”、“上”、 “下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
瞄准镜常用于安装在枪械上，以提高瞄准精度、降低射击难度。在本申请中，“目方”的含义为瞄准镜在实际操作过程中靠近射手的一端，“物方”的含义为瞄准镜在实际操作过程中靠近目标的一端，即远离射手的一端。
现有红点瞄准镜通常包括光源、反射镜、准直物镜和分光棱镜，其中，光源用于朝目方出射光线，光源出射的光线会先经反射镜转向至准直物镜，再通过准直物镜转换成平行光，最后再经过分光棱镜转向并射入人眼。基于 此，由于光源出射的光线朝向目方，从物方将基本观察不到光源的亮点，从而可降低射手暴露的风险。
但是在瞄准近距离的目标时，由于目标的光并非是平行光，而是具有一定发散角度的发散光，人眼为了能够看清目标，会自动调节晶状体来使目标成像于视网膜，而光源出射的光线经过准直物镜转换后却是平行光，此时人眼的晶状体形状已改变，因此光源出射的光线将成像在视网膜前方，导致光源出射的光线的成像与目标的成像没有在视网膜上叠加，进而会产生视差，具体表现为晃动头部时，光源出射的光线的成像与目标成像的相对位置会发生改变，这样就会影响瞄准的精准度。
对此，本申请实施例提供了新型的红点瞄准镜，不仅可隐藏光源的亮点以降低射手暴露的风险，且还可在瞄准距离不同时保障视差在允许范围内，进而保障并提高瞄准精准度。
以下结合具体实施例对本申请的具体实现进行更加详细的描述：
实施例一
请参阅图1、图3，本申请实施例提供了一种红点瞄准镜，包括镜座10、镜框20、光源件30、准直镜组40、反射镜50和分光棱镜60。镜座10的内部设有沿其轴向延伸形成的第一腔11，第一腔11靠近物方的一端连通至外部；镜框20设于镜座10靠近目方的周侧，镜框20的内部设有沿其轴向贯通的第二腔21，以及连通第二腔21和第一腔11的通口22；光源件30设于第一腔11靠近物方的一端，且用于朝目方出射光线，光源件30相对于镜座10的轴向位置可调；准直镜组40设于第一腔11，且设于光源件30靠近目方的一侧；反射镜50设于第一腔11，且与通口22对应设置；分光棱镜60设于 第二腔21，分光棱镜60包括相互胶合的第一棱镜61和第二棱镜62，第一棱镜61和第二棱镜62的胶合面上设有反射膜70。
在此需要说明的是，光源件30、准直镜组40和反射镜50均容纳于镜座10的第一腔11内，镜座10可对设于第一腔11的光源件30、准直镜组40和反射镜50进行可靠防护。
光源件30安装在第一腔11靠近物方的一端，且用于朝准直镜组40出射光线。基于此，由于光源件30出射的光线朝向目方，可基本避免目标从物方观察到亮点，进而可降低射手暴露的风险。其中，光源件30可受力沿镜座10的轴向往复移动，以调节其至准直镜组40的距离。其中，光源件30包括用于朝准直镜组40出射光线的发光元件31，以及用于支撑、固定发光元件31的灯座32，发光元件31的光轴与准直镜组40的光轴对准，发光元件31可为但不限于为LED(Light-Emitting Diode，发光二极管)灯。
准直镜组40安装在第一腔11的从光源件30至通口22的空间内，准直镜组40用于对光源件30出射的光线进行折射。具体地，当光源件30至准直镜组40的距离为调校距离时，准直镜组40可将光源件30出射的光线折射成近似平行光；以调校距离为基准，再带动光源件30朝靠近或远离准直镜组40的方向移动，以调节光源件30至准直镜组40的距离，即可改变准直镜组40对光源件30出射的光线的折射效果，例如使准直镜组40将光源件30出射的光线折射成发散光。
反射镜50与通口22对应设置，反射镜50倾斜于第一腔11的中轴线且倾斜于通口22的中轴线。反射镜50不具有屈光能力，主要用于将沿第一腔11传播的光线经由通口22反射、转向至分光棱镜60。
在此还需要说明的是，分光棱镜60限位容纳于镜框20的第二腔21内，镜框20可对设于第二腔21的分光棱镜60进行可靠防护。
分光棱镜60包括相互胶合的第一棱镜61和第二棱镜62。第一棱镜61和第二棱镜62的胶合面倾斜于第二腔21的中轴线且倾斜于通口22的中轴线，第一棱镜61和第二棱镜62的胶合面上设有反射膜70，反射膜70用于反射特定波长的光线并允许其他波长的光线透过，具体地，反射膜70用于将反射镜50反射的光线进一步反射至目方，并允许从第二腔21靠近物方的一端而来的目标光线透过其射向目方。其中，反射膜70可采用但不限于镀膜的方式设置在第一棱镜61的胶合面或第二棱镜62的胶合面上。
综上，本申请实施例提供的红点瞄准镜的工作原理基本为：在出厂时预先按照远距离目标进行调校。如图1、图2所示，当红点瞄准镜瞄准远距离目标时，远距离目标的光将以近似平行光穿过第二腔21和反射膜70射入目方，此时，可保持光源件30相对于镜座10的轴向位置不变，以保障光源件30和准直镜组40之间维持调校距离，这样，光源件30所出射的光线即可经由准直镜组40折射成近似平行光，并经由反射镜50反射至分光棱镜60，再经由分光棱镜60的第一棱镜61和第二棱镜62的胶合面上的反射膜70反射至目方，由此，即使人眼为了能够看清目标而自动调节晶状体使得目标成像于视网膜，由于来源于光源件30的光线与远距离目标的光在射入目方时近似平行，来源于光源件30的光线能够与远距离目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障并提高瞄准的精准度。
反之，如图3、图4所示，当红点瞄准镜瞄准近距离目标时，近距离目标的光将以具有一定发散角度的发散光穿过第二腔21和反射膜70射入目方， 此时，可带动光源件30相对于镜座10朝远离或靠近准直镜组40的方向移动，以调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，直至“光源件30所出射的光线可经由准直镜组40折射成发散光，且经由反射镜50和分光棱镜60的反射膜70多重反射至目方时的入射角度与近距离目标的光射入目方的角度近似相等”，由此，即使人眼为了能够看清目标而自动调节晶状体使得目标成像于视网膜，由于来源于光源件30的光线与近距离目标的光在射入目方时均为发散光，且射入人眼的角度近似相等，来源于光源件30的光线能够与近距离目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障并提高瞄准的精准度。
因而，本申请实施例提供的红点瞄准镜，通过将光源件30、准直镜组40、反射镜50设置在镜座10内部并将分光棱镜60设置在镜框20内部，以通过光源件30朝准直镜组40出射光线，通过准直镜组40对光源件30出射的光线进行折射，通过反射镜50和设于第一棱镜61和第二棱镜62上的反射膜70将来源于光源件30的光线多重反射至目方，基于此，即可有效保障光源件30及其出射的光线的隐蔽性，可基本避免目标从物方观察到亮点，进而可有效降低射手暴露的风险。在此基础上，本申请实施例提供的红点瞄准镜，还可根据瞄准距离的不同，通过调节光源件30相对于镜座10的轴向位置，以调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，从而可促使来源于光源件30的光线与目标的光在射入目方时的入射角度近似相等、基本一致，可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。因此，本申 请实施例提供的红点瞄准镜，可以应用于多种瞄准距离的场合，适应范围广。
此外，现有红点瞄准镜在瞄准近距离的目标时，由于红点瞄准镜的瞄准点成像与目标成像没有在视网膜上叠加成像，导致人眼为了能够看清其中之一成像会不断调整晶状体，这样会导致眼睛容易疲劳，导致红点瞄准镜的瞄准舒适性较差。对此，本申请实施例提供的红点瞄准镜在瞄准距离不同时，由于可调节光源件30相对于镜座10的轴向位置、可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可保障人眼能够自动调节晶状体并同时看清红点瞄准镜的瞄准点成像与目标成像，从而可有效保障并提高红点瞄准镜的瞄准舒适性，可有效降低眼睛的疲劳度。
此外，现有红点瞄准镜在瞄准距离不同时会产生不同的、较大的视差，当现有红点瞄准镜靠近目方的一侧安装有倍率镜时，射手只要稍微摆头观看倍率镜，在放大的视场中都可以很明显看到红点瞄准镜的瞄准点快速移动，并非与目标对准、相对位置固定，这样会导致射手难以瞄准。对此，本申请实施例提供的红点瞄准镜在瞄准距离不同时，由于可调节光源件30相对于镜座10的轴向位置、可消除视差、可保障在瞄准距离不同时视差在允许范围内，当红点瞄准镜靠近目方的一侧安装有倍率镜时，即使射手摆头观看倍率镜，在放大的视场中可以看到放大一定倍率、对准、相对位置固定的红点瞄准镜的瞄准点以及目标，从而可有效保障并提高射手的瞄准精度和瞄准舒适性，因此，本申请实施例提供的红点瞄准镜尤其适用于与倍率镜一起使用，优势更凸显。
请参阅图1、图3，在本实施例中，光源件30与镜座10螺纹连接。具体地，镜座10的第一腔11的内壁设有内螺纹，光源件30的灯座32的外侧设 有外螺纹，光源件30的灯座32螺纹连接至镜座10。
通过采用上述方案，可通过将光源件30螺纹连接于镜座10，而简便、快捷地实现光源件30与镜座10之间的组装，还可在使用时，通过旋转光源件30，而实现调节光源件30相对于镜座10的轴向位置，调节操作简便、快捷，且利于稳定、固定光源件30在调节后相对于镜座10的轴向位置。
请参阅图1、图3，在本实施例中，准直镜组40包括从物方到目方依次设置且均具有屈光能力的第一透镜41、第二透镜42和第三透镜43；第一透镜41和第二透镜42设于光源件30和反射镜50之间，第三透镜43设于通口22。
基于本实施例的设置，当光源件30朝准直镜组40出射光线时，光线会先经过第一透镜41，以由第一透镜41对光线进行第一重折射，随后，光线会再经过第二透镜42，以由第二透镜42对光线进行第二重折射，随后，光线会抵达反射镜50并被反射镜50反射至通口22，随后，光线会经过设于通口22的第三透镜43，以由第三透镜43对光线进行第三重折射，至此，准直镜组40可完成对光源件30出射的光线的折射。而通过调节光源件30至第一透镜41的距离，可改变准直镜组40对光源件30出射的光线的折射效果，如图2、图4所示。
并且，相对于实施例九，本实施例的设置可相对缩短红点瞄准镜的长度。
当然，在其他可能的实施方式中，准直镜组40可采用其他结构方案实现对光源件30出射的光线进行折射，例如准直镜组40可包括准直物镜胶合镜，本实施例对此不做限制。
请参阅图1、图3，在本实施例中，红点瞄准镜还包括与光源件30电连 接且用于为光源件30供电的电池(图中未示出)和/或太阳能电池板80。
其中，太阳能电池板80优选设置在镜框20或镜座10的顶侧表面，如此设置，可保障太阳能电池板80可较大程度地接收到太阳光，进而可提高太阳能电池板80的蓄电性能和供电性能。
其中，电池可选设置在镜座10的内部。
其中，当红点瞄准镜同时具有太阳能电池板80和电池时，红点瞄准镜可通过控制板自主/切换选择太阳能电池板80或电池为光源供电。
实施例二
本实施例与实施例一的区别在于：

在此需要说明的是，内管90安装于第一腔11中，内管90的第一球头91铰接于第一球窝111且被限制脱离第一球窝111，基于此，在内管90的端部受力时，内管90即可绕第一球头91进行一定幅度的平稳、可靠的转动。
第一调节机构100穿设安装于镜座10并设置在内管90靠近目方的一端，可用于对内管90靠近目方的一端施加作用力，以带动内管90绕第一球头91进行可控幅度的转动，基于此，即可便捷、可控地实现将安装于内管90的第三腔92的光源件30的光轴调节至与准直镜组40的光轴对准，进而可有效消 除组装误差，可有效保障并提高红点瞄准镜的瞄准点的位置精度，可有效保障并提高瞄准精准度。其中，请参考图7，第一调节机构100包括第一弹道调节钉101和第一风偏调节钉102，第一弹道调节钉101设于内管90沿竖直方向上的一侧，可用于对内管90靠近目方的一端施加竖直方向的作用力，以实现内管90、光源件30尤其光源件30的光轴在竖直方向的位移调节；第一风偏调节钉102设于内管90沿水平方向上的一侧，可用于对内管90靠近目方的一端施加水平作用力，以实现内管90、光源件30尤其光源件30的光轴在水平方向的位移调节。基于此，第一调节机构100即可快速、便捷地实现将光源件30的光轴调节至与准直镜组40的光轴对准。
光源件30安装于内管90的第三腔92中，光源件30相对于内管90的轴向位置可调。基于此，即可通过调节光源件30相对于内管90的轴向位置，实现调节光源件30相对于镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
请参阅图5，在本实施例中，光源件30与内管90螺纹连接。具体地，内管90的第三腔92的内壁设有内螺纹，光源件30的灯座32的外侧设有外螺纹，光源件30的灯座32螺纹连接至内管90。
通过采用上述方案，可通过将光源件30螺纹连接于内管90，而简便、快捷地实现光源件30与内管90之间的组装，还可在使用时，通过旋转光源件30，而实现调节光源件30相对于内管90的轴向位置，调节操作简便、快 捷，且利于稳定、固定光源件30在调节后相对于内管90的轴向位置。
由于螺纹配合属于间隙配合，内管90的第三腔92的内螺纹与光源件30的灯座32的外螺纹之间存在较小间隙，导致在调节时需先空转光源件30补足间隙，再旋转光源件30而实现调节光源件30相对于内管90的轴向位置，但这个间隙以及空转的动作，都会影响调节精度。
对此，请参阅图5，在本实施例中，红点瞄准镜还包括第一弹簧110，第一弹簧110设于第三腔92，第一弹簧110沿轴向的相对两端分别连接光源件30和内管90。通过采用上述方案，可通过第一弹簧110沿轴向的相对两端分别弹性抵持光源件30和内管90，基于此，即可经由第一弹簧110对光源件30的弹性抵持力，促使光源件30的外螺纹的螺牙与内管90的内螺纹的螺牙相抵紧，从而可有效消除光源件30的外螺纹与内管90的内螺纹之间的间隙，可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
此外，当螺纹加工误差较大，导致光源件30的外螺纹与内管90的内螺纹之间配合较为松动时，基于本实施例的设置，也可有效缓解甚至避免光源件30的外螺纹与内管90的内螺纹之间配合出现松动的情况，进而可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。

在此需要说明的是，第一调节杆120安装于第一安装孔921中，且在外力作用下可于第一安装孔921中绕第一调节杆120的中轴线进行自转。
第一压圈130可采用但不限于采用螺纹连接和/或胶水粘接的方式连接于内管90靠近物方的一端，第一压圈130压紧、抵止于第一调节杆120，并将第一调节杆120限位在第一安装孔921中，第一压圈130尤其可限制第一调节杆120相对于第一安装孔921轴向移动，尤其可限制第一调节杆120脱出第一安装孔921。第一调节杆120靠近物方的一端从第一压圈130的内圈露出或凸出，以便于外力带动第一调节杆120自转。
光源件30的一端连接于第一调节杆120的第一连接孔121，光源件30的另一端穿设于第一穿孔922，当第一调节杆120在外力作用下转动时，光源件30可相对于第一穿孔922轴向移动，而实现调节光源件30相对于内管90和镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在 瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
由此，相对于实施例二，本实施例通过转动第一调节杆120以带动光源件30轴向移动，不仅可实现光源件30的轴向位置的调节，且还可在调节期间保障供射手调节操作的区域(即第一调节杆120靠近物方的一端)维持轴向位置基本不变，进而可更便于射手进行调节操作。
请参阅图6，在本实施例中，光源件30的端部螺纹连接于第一连接孔121，第一穿孔922为非圆孔，并限制光源件30相对于第一穿孔922转动。其中，第一穿孔922为非圆孔，具体可为多边形孔或异形孔等等。其中，光源件30穿设于第一穿孔922的部分的截面形状相同于第一穿孔922的形状。
通过采用上述方案，当第一调节杆120在外力作用下转动时，由于光源件30被第一穿孔922限制转动，光源件30可在第一调节杆120的第一连接孔121的螺纹的带动下相对于第一穿孔922轴向移动，进而可实现调节光源件30相对于内管90和镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
由于光源件30仅相对于第一穿孔922轴向移动而不相对于第一穿孔922转动，本实施例尤其适用于采用多点LED和/或分划图案的光源件30，这样，只要在红点瞄准镜出厂前预先将光源件30的多点和/或分划图案调校好，在调节光源件30的轴向位置时，光源件30的多点和/或分划图案即可保持调校状态而不转动，进而更利于保障并提高瞄准精准度。其中，分划图案可为但 不限于为圈点式分划图案、带水平线和竖直线的分划图案等等。
由于螺纹配合属于间隙配合，光源件30的外螺纹与对应内螺纹之间的配合存在较小间隙，导致在调节时需先空转补足间隙，再旋转才能实现调节光源件30相对于内管90和镜座10的轴向位置，但这个间隙以及空转的动作，都会影响调节精度。
对此，请参阅图6，在本实施例中，红点瞄准镜还包括第二弹簧140，第二弹簧140设于第一连接孔121；第二弹簧140沿轴向的相对两端分别连接光源件30和第一调节杆120。通过采用上述方案，可通过第二弹簧140沿轴向的相对两端分别弹性抵持光源件30和第一调节杆120，基于此，即可经由第二弹簧140对光源件30的弹性抵持力，促使光源件30的外螺纹的螺牙与对应内螺纹的螺牙相抵紧，从而可有效消除光源件30的外螺纹与对应内螺纹之间的间隙，可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
并且，当螺纹加工误差较大，导致光源件30的外螺纹与对应内螺纹之间配合较为松动时，基于本实施例的设置，也可有效缓解甚至避免光源件30的外螺纹与对应内螺纹之间配合出现松动的情况，进而可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。

通过采用上述方案，当第一调节杆120在外力作用下转动时，由于光源件30被第一调节杆120的第一连接孔121限制相对偏转，光源件30将随第一调节杆120发生同步转动，基于此，光源件30即可在第一穿孔922的螺纹的带动下相对于第一穿孔922轴向移动，进而可实现调节光源件30相对于内管90和镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
实施例五

请参考图6，在本实施例中，红点瞄准镜还包括第二弹簧140，第二弹簧140设于第一连接孔121；第二弹簧140沿轴向的相对两端分别连接光源件30和内管90。
通过采用上述方案，可通过第二弹簧140沿轴向的相对两端分别弹性抵持光源件30和内管90，基于此，即可经由第二弹簧140对光源件30的弹性抵持力，促使光源件30的外螺纹的螺牙与对应内螺纹的螺牙相抵紧，从而可有效消除光源件30的外螺纹与对应内螺纹之间的间隙，可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
并且，当螺纹加工误差较大，导致光源件30的外螺纹与对应内螺纹之间配合较为松动时，基于本实施例的设置，也可有效缓解甚至避免光源件30的 外螺纹与对应内螺纹之间配合出现松动的情况，进而可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
实施例六
本实施例与实施例一的区别在于：
请参阅图8，在本实施例中，第一腔11靠近物方的一端设有从物方到目方依次设置的第二安装孔112和第二穿孔113，换言之，镜座10靠近物方的端面开设有第二安装孔112，第二安装孔112的孔底开设有第二穿孔113，第二安装孔112和第二穿孔113构成第一腔11靠近物方的一端。
红点瞄准镜还包括第二调节杆150和第二压圈160，第二调节杆150转动安装于第二安装孔112，第二压圈160连接于镜座10靠近物方的一端并限制第二调节杆150沿第二安装孔112轴向移动，第二调节杆150靠近目方的一端设有沿轴向延伸的第二连接孔151，光源件30的一端连接于第二连接孔151，光源件30的另一端穿设于第二穿孔113，第二调节杆150在转动时能够带动光源件30相对于第二穿孔113轴向移动。
在此需要说明的是，第二调节杆150安装于第二安装孔112中，且在外力作用下可于第二安装孔112中绕第二调节杆150的中轴线进行自转。
第二压圈160可采用但不限于采用螺纹连接和/或胶水粘接的方式连接于镜座10靠近物方的一端，第二压圈160压紧、抵止于第二调节杆150，并将第二调节杆150限位在第二安装孔112中，第二压圈160尤其可限制第二调节杆150相对于第二安装孔112轴向移动，尤其可限制第二调节杆150脱出第二安装孔112。第二调节杆150靠近物方的一端从第二压圈160的内圈露出或凸出，以便于外力带动第二调节杆150自转。
光源件30的一端连接于第二调节杆150的第二连接孔151，光源件30的另一端穿设于第二穿孔113，当第二调节杆150在外力作用下转动时，光源件30可相对于第二穿孔113轴向移动，而实现调节光源件30相对于镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
由此，相对于实施例一，本实施例通过转动第二调节杆150以带动光源件30轴向移动，不仅可实现光源件30的轴向位置的调节，且还可在调节期间保障供射手调节操作的区域(即第二调节杆150靠近物方的一端)维持轴向位置基本不变，进而可更便于射手进行调节操作。
请参阅图8，在本实施例中，光源件30的端部螺纹连接于第二连接孔151，第二穿孔113为非圆孔，并限制光源件30相对于第二穿孔113转动。其中，第二穿孔113为非圆孔，具体可为多边形孔或异形孔等等。其中，光源件30穿设于第二穿孔113的部分的截面形状相同于第二穿孔113的形状。
通过采用上述方案，当第二调节杆150在外力作用下转动时，由于光源件30被第二穿孔113限制转动，光源件30可在第二调节杆150的第二连接孔151的螺纹的带动下相对于第二穿孔113轴向移动，进而可实现调节光源件30相对于镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。
由于光源件30仅相对于第二穿孔113轴向移动而不相对于第二穿孔113转动，本实施例尤其适用于采用多点LED和/或分划图案的光源件30，这样，只要在红点瞄准镜出厂前预先将光源件30的多点和/或分划图案调校好，在调节光源件30的轴向位置时，光源件30的多点和/或分划图案即可保持调校状态而不转动，进而更利于保障并提高瞄准精准度。其中，分划图案可为但不限于为圈点式分划图案、带水平线和竖直线的分划图案等等。
由于螺纹配合属于间隙配合，光源件30的外螺纹与对应内螺纹之间的配合存在较小间隙，导致在调节时需先空转补足间隙，再旋转才能实现调节光源件30相对于镜座10的轴向位置，但这个间隙以及空转的动作，都会影响调节精度。
对此，请参阅图8，在本实施例中，红点瞄准镜还包括第三弹簧170，第三弹簧170设于第二连接孔151；第三弹簧170沿轴向的相对两端分别连接光源件30和第二调节杆150。通过采用上述方案，可通过第三弹簧170沿轴向的相对两端分别弹性抵持光源件30和第二调节杆150，基于此，即可经由第三弹簧170对光源件30的弹性抵持力，促使光源件30的外螺纹的螺牙与对应内螺纹的螺牙相抵紧，从而可有效消除光源件30的外螺纹与对应内螺纹之间的间隙，可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
并且，当螺纹加工误差较大，导致光源件30的外螺纹与对应内螺纹之间配合较为松动时，基于本实施例的设置，也可有效缓解甚至避免光源件30的外螺纹与对应内螺纹之间配合出现松动的情况，进而可有效保障并提高光源件30的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
实施例七
本实施例与实施例六的区别在于：

通过采用上述方案，当第二调节杆150在外力作用下转动时，由于光源件30被第二调节杆150的第二连接孔151限制相对偏转，光源件30将随第二调节杆150发生同步转动，基于此，光源件30即可在第二穿孔113的螺纹的带动下相对于第二穿孔113轴向移动，进而可实现调节光源件30相对于镜座10的轴向位置，调节光源件30至准直镜组40的距离，调节准直镜组40对光源件30出射的光线的折射效果，进而可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。

实施例九
本实施例与实施例一的区别在于：
请参阅图9、图10，在本实施例中，准直镜组40包括从物方到目方依次设置且均具有屈光能力的第一透镜41、第二透镜42和第三透镜43；第一透镜41、第二透镜42和第三透镜43设于光源件30和反射镜50之间。
基于本实施例的设置，当光源件30朝准直镜组40出射光线时，光线会先经过第一透镜41，以由第一透镜41对光线进行第一重折射，随后，光线会再经过第二透镜42，以由第二透镜42对光线进行第二重折射，随后，光线会再经过第三透镜43，以由第三透镜43对光线进行第三重折射，至此，准直镜组40可在光线抵达反射镜50之前完成对光源件30出射的光线的折射。而通过调节光源件30至第一透镜41的距离，可改变准直镜组40对光源件30出射的光线的折射效果。
实施例十
请参阅图11、图12，本申请实施例还提供一种红点瞄准镜，包括镜座10、镜框20、光源件30、反射镜50、分光棱镜60和准直镜组40。镜座10 的内部设有沿其轴向延伸形成的第一腔11；镜框20设于镜座10靠近目方的周侧，镜框20的内部设有沿其轴向贯通的第二腔21，以及连通第二腔21和第一腔11的通口22；光源件30设于第一腔11靠近物方的一端，且用于朝目方出射光线；反射镜50设于第一腔11，且与通口22对应设置；分光棱镜60设于第二腔21，分光棱镜60包括相互胶合的第一棱镜61和第二棱镜62，第一棱镜61和第二棱镜62的胶合面上设有反射膜70；准直镜组40设于第一腔11，准直镜组40包括依次设置且均具有屈光能力的第一透镜41、第二透镜42和第三透镜43，第一透镜41和第二透镜42设于光源件30和反射镜50之间，第三透镜43设于第二透镜42至分光棱镜60之间，第一透镜41和第三透镜43相对于镜座10固定，第二透镜42相对于镜座10的轴向位置可调。
在此需要说明的是，光源件30、准直镜组40和反射镜50均容纳于镜座10的第一腔11内，镜座10可对设于第一腔11的光源件30、准直镜组40和反射镜50进行可靠防护。
光源件30安装在第一腔11靠近物方的一端，且用于朝准直镜组40出射光线。基于此，由于光源件30出射的光线朝向目方，可基本避免目标从物方观察到亮点，进而可降低射手暴露的风险。其中，光源件30相对于镜座10的轴向位置确定、固定。其中，光源件30包括用于朝准直镜组40出射光线的发光元件31，以及用于支撑、固定发光元件31的灯座32，发光元件31的光轴与准直镜组40的光轴对准，发光元件31可为但不限于为LED灯。
准直镜组40安装在第一腔11的从光源件30至通口22的空间内，准直镜组40用于对光源件30出射的光线进行折射。准直镜组40包括依次设置且 均具有屈光能力的第一透镜41、第二透镜42和第三透镜43，准直镜组40可通过第一透镜41、第二透镜42和第三透镜43对光源件30出射的光线进行多重折射。具体地，如图11所示，在第一种实施方式中，第一透镜41和第二透镜42设于光源件30和反射镜50之间，第三透镜43设于通口22，基于此，当光源件30朝准直镜组40出射光线时，光线会先经过第一透镜41，以由第一透镜41对光线进行第一重折射，随后，光线会再经过第二透镜42，以由第二透镜42对光线进行第二重折射，随后，光线会抵达反射镜50并被反射镜50反射至通口22，随后，光线会经过设于通口22的第三透镜43，以由第三透镜43对光线进行第三重折射，至此，准直镜组40可完成对光源件30出射的光线的折射。请参考图9，在第二种实施方式中，第一透镜41、第二透镜42和第三透镜43设于光源件30和反射镜50之间，基于此，当光源件30朝准直镜组40出射光线时，光线会先经过第一透镜41，以由第一透镜41对光线进行第一重折射，随后，光线会再经过第二透镜42，以由第二透镜42对光线进行第二重折射，随后，光线会再经过第三透镜43，以由第三透镜43对光线进行第三重折射，至此，准直镜组40可在光线抵达反射镜50之前完成对光源件30出射的光线的折射。其中，相对于第二种实施方式，采用第一种实施方式可相对缩短红点瞄准镜的长度。
其中，第一透镜41和第三透镜43相对于镜座10固定，第二透镜42相对于镜座10的轴向位置可调，当第二透镜42至光源件30的距离为调校距离时，第二透镜42可配合第一透镜41和第三透镜43将光源件30出射的光线多重折射成近似平行光；以调校距离为基准，再带动第二透镜42朝靠近或远离光源件30的方向移动，以调节第二透镜42至光源件30的距离，即可改变 准直镜组40对光源件30出射的光线的折射效果，例如将光源件30出射的光线多重折射成发散光。
反射镜50与通口22对应设置，反射镜50倾斜于第一腔11的中轴线且倾斜于通口22的中轴线。反射镜50不具有屈光能力，主要用于将沿第一腔11传播的光线经由通口22反射、转向至分光棱镜60。
在此还需要说明的是，分光棱镜60限位容纳于镜框20的第二腔21内，镜框20可对设于第二腔21的分光棱镜60进行可靠防护。
分光棱镜60包括相互胶合的第一棱镜61和第二棱镜62。第一棱镜61和第二棱镜62的胶合面倾斜于第二腔21的中轴线且倾斜于通口22的中轴线，第一棱镜61和第二棱镜62的胶合面上设有反射膜70，反射膜70用于反射特定波长的光线并允许其他波长的光线透过，具体地，反射膜70用于将反射镜50反射的光线进一步反射至目方，并允许从第二腔21靠近物方的一端而来的目标光线透过其射向目方。其中，反射膜70可采用但不限于镀膜的方式设置在第一棱镜61的胶合面或第二棱镜62的胶合面上。
综上，本申请实施例提供的红点瞄准镜的工作原理基本为：在出厂时预先按照远距离目标进行调校。当红点瞄准镜瞄准远距离目标时，远距离目标的光将以近似平行光穿过第二腔21和反射膜70射入目方，此时，可保持第二透镜42相对于镜座10的轴向位置不变，以保障光源件30和第二透镜42之间维持调校距离，这样，光源件30所出射的光线即可经由准直镜组40的第一透镜41、第二透镜42和第三透镜43多重折射成近似平行光，并经由反射镜50反射至分光棱镜60，再经由分光棱镜60的第一棱镜61和第二棱镜62的胶合面上的反射膜70反射至目方，由此，即使人眼为了能够看清目标 而自动调节晶状体使得目标成像于视网膜，由于来源于光源件30的光线与远距离目标的光在射入目方时近似平行，来源于光源件30的光线能够与远距离目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障并提高瞄准的精准度。
反之，当红点瞄准镜瞄准近距离目标时，近距离目标的光将以具有一定发散角度的发散光穿过第二腔21和反射膜70射入目方，此时，可带动第二透镜42相对于镜座10朝远离或靠近光源件30的方向移动，以调节第二透镜42至光源件30的距离，调节准直镜组40对光源件30出射的光线的折射效果，直至“光源件30所出射的光线可经由准直镜组40的第一透镜41、第二透镜42和第三透镜43多重折射成发散光，且经由反射镜50和分光棱镜60的反射膜70多重反射至目方时的入射角度与近距离目标的光射入目方的角度近似相等”，由此，即使人眼为了能够看清目标而自动调节晶状体使得目标成像于视网膜，由于来源于光源件30的光线与近距离目标的光在射入目方时均为发散光，且射入人眼的角度近似相等，来源于光源件30的光线能够与近距离目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障并提高瞄准的精准度。
因而，本申请实施例提供的红点瞄准镜，通过将光源件30、准直镜组40、反射镜50设置在镜座10内部并将分光棱镜60设置在镜框20内部，以通过光源件30朝准直镜组40出射光线，通过准直镜组40对光源件30出射的光线进行折射，通过反射镜50和设于第一棱镜61和第二棱镜62上的反射膜70将来源于光源件30的光线多重反射至目方，基于此，即可有效保障光源件30及其出射的光线的隐蔽性，可基本避免目标从物方观察到亮点，进而可 有效降低射手暴露的风险。在此基础上，本申请实施例提供的红点瞄准镜，还可根据瞄准距离的不同，通过调节准直镜组40的第二透镜42相对于镜座10的轴向位置，以调节准直镜组40的第二透镜42至光源件30的距离，调节准直镜组40对光源件30出射的光线的折射效果，从而可促使来源于光源件30的光线与目标的光在射入目方时的入射角度近似相等、基本一致，可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，进而可有效消除视差，可有效保障在瞄准距离不同时视差在允许范围内，可有效保障并提高瞄准的精准度。因此，本申请实施例提供的红点瞄准镜，可以应用于多种瞄准距离的场合，适应范围广。
此外，现有红点瞄准镜在瞄准近距离的目标时，由于红点瞄准镜的瞄准点成像与目标成像没有在视网膜上叠加成像，导致人眼为了能够看清其中之一成像会不断调整晶状体，这样会导致眼睛容易疲劳，导致红点瞄准镜的瞄准舒适性较差。对此，本申请实施例提供的红点瞄准镜在瞄准距离不同时，由于可调节准直镜组40的第二透镜42相对于镜座10的轴向位置、可促使来源于光源件30的光线能够与目标的光在视网膜上叠加成像，可保障人眼能够自动调节晶状体并同时看清红点瞄准镜的瞄准点成像与目标成像，从而可有效保障并提高红点瞄准镜的瞄准舒适性，可有效降低眼睛的疲劳度。
此外，现有红点瞄准镜在瞄准距离不同时会产生不同的、较大的视差，当现有红点瞄准镜靠近目方的一侧安装有倍率镜时，射手只要稍微摆头观看倍率镜，在放大的视场中都可以很明显看到红点瞄准镜的瞄准点快速移动，并非与目标对准、相对位置固定，这样会导致射手难以瞄准。对此，本申请实施例提供的红点瞄准镜在瞄准距离不同时，由于可调节准直镜组40的第二 透镜42相对于镜座10的轴向位置、可消除视差、可保障在瞄准距离不同时视差在允许范围内，当红点瞄准镜靠近目方的一侧安装有倍率镜时，即使射手摆头观看倍率镜，在放大的视场中可以看到放大一定倍率、对准、相对位置固定的红点瞄准镜的瞄准点以及目标，从而可有效保障并提高射手的瞄准精度和瞄准舒适性，因此，本申请实施例提供的红点瞄准镜尤其适用于与倍率镜一起使用，优势更凸显。
请参阅图11、图13，在本实施例中，准直镜组40还包括安装第一透镜41的第一透镜座180，以及安装第二透镜42的第二透镜座190，第一透镜座180固定安装于第一腔11，第二透镜座190滑动安装于第一腔11。
通过采用上述方案，可通过第一透镜座180安装第一透镜41，以稳定、固定第一透镜41相对于第一透镜座180的安装状态，再通过将第一透镜座180固定安装于第一腔11，而确定、固定第一透镜41相对于镜座10的安装位置和状态。
通过采用上述方案，可通过第二透镜座190安装第二透镜42，以稳定、固定第二透镜42相对于第二透镜座190的安装状态，再通过将第二透镜座190滑动安装于第一腔11，而实现在稳定第二透镜42的光轴准直的基础上，通过第二透镜座190的滑动改变第二透镜42相对于镜座10的轴向位置。
请参阅图11、图13、图14，在本实施例中，镜座10的周面设有第三安装孔12，第三安装孔12的孔底设有连通至第一腔11的第三穿孔13，第三穿孔13为沿镜座10的轴向延伸形成的腰型孔；红点瞄准镜还包括调焦机构200，调焦机构200包括调焦手轮201和拨杆202，调焦手轮201转动安装于第三安装孔12，并被限制沿第三安装孔12轴向移动，调焦手轮201靠近第三安 装孔12的孔底的端面设有曲线槽2011，曲线槽2011沿调焦手轮201的周向延伸形成，且曲线槽2011的中心线逐渐靠近调焦手轮201的中轴线，拨杆202的一端滑动连接于曲线槽2011，拨杆202的另一端穿设于第三穿孔13并与第二透镜座190连接，调焦手轮201在转动时能够带动第二透镜座190于第一腔11滑动。
在此需要说明的是，调焦手轮201安装于第三安装孔12中，被限制沿第三安装孔12轴向移动，且在外力作用下可于第三安装孔12中绕调焦手轮201的中轴线进行自转。
拨杆202的一端滑动连接于调焦手轮201的曲线槽2011，拨杆202的另一端穿过第三穿孔13并与第二透镜座190固定连接或可拆卸连接，其中，拨杆202可选与第二透镜座190螺纹连接。基于此，当调焦手轮201正向(与下文的反向为相对概念)转动时，调焦手轮201的曲线槽2011可驱使拨杆202沿曲线槽2011向靠近调焦手轮201的中轴线的一侧滑动，同时由于拨杆202穿设于第三穿孔13，第三穿孔13可对拨杆202的移动方向进行导向、约束，从而使得拨杆202可带动第二透镜座190和第二透镜42朝靠近光源件30的方向进行轴向移动。反之，当调焦手轮201反向转动时，调焦手轮201的曲线槽2011可驱使拨杆202沿曲线槽2011向远离调焦手轮201的中轴线的一侧滑动，同时由于拨杆202穿设于第三穿孔13，第三穿孔13可对拨杆202的移动方向进行导向、约束，从而使得拨杆202可带动第二透镜座190和第二透镜42朝远离光源件30的方向进行轴向移动。由此，即可通过调焦机构200快速、便捷地实现第二透镜42相对于镜座10和光源件30的轴向位置的调节。
请参阅图11、图13，在本实施例中，第三安装孔12的孔底设有第三连接孔14；调焦机构200还包括锁紧螺钉203，锁紧螺钉203的钉部穿设于调焦手轮201并与第三连接孔14螺纹连接，锁紧螺钉203的头部压紧调焦手轮201并限制调焦手轮201沿第三安装孔12轴向移动。
基于本实施例的设置，锁紧螺钉203的钉部可采用螺纹连接的方式连接于第三连接孔14，而稳定其安装位置和安装状态；在此基础上，锁紧螺钉203的头部可压紧、抵止于调焦手轮201，而将调焦手轮201限位在第三安装孔12中，锁紧螺钉203尤其可限制调焦手轮201相对于第三安装孔12轴向移动，尤其可限制调焦手轮201脱出第三安装孔12。
请参阅图11、图13，在本实施例中，红点瞄准镜还包括弹性抵持于第一透镜座180和第二透镜座190之间的第四弹簧210。
通过采用上述方案，可通过第四弹簧210沿轴向的相对两端分别弹性抵持第一透镜座180和第二透镜座190，以保障并提高第二透镜座190在相对于镜座10发生轴向移动时的移动平稳性，保障并提高第二透镜座190在调节后相对于镜座10的轴向位置的稳定性。
当拨杆202与第二透镜座190螺纹连接时，由于螺纹配合属于间隙配合，拨杆202的外螺纹与第二透镜座190的内螺纹之间存在较小间隙，导致在调节时调焦手轮201先空转以补足拨杆202和第二透镜座190之间的配合间隙，再旋转才能实现通过拨杆202带动第二透镜座190和第二透镜42相对于镜座10和光源件30轴向移动，但这个间隙以及空转的动作，都会影响调节精度。对此，通过采用上述方案，可通过第四弹簧210沿轴向的相对两端分别弹性抵持第一透镜座180和第二透镜座190，以经由第四弹簧210对第二透镜座 190的弹性抵持力，促使第二透镜座190的内螺纹与拨杆202的外螺纹相抵紧，从而可有效消除第二透镜座190的内螺纹与拨杆202的外螺纹之间的间隙，可有效保障并提高第二透镜42的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
当拨杆202与第二透镜座190螺纹连接，螺纹加工误差较大，导致拨杆202的外螺纹与第二透镜座190的内螺纹之间配合较为松动时，通过采用上述方案，可有效缓解甚至避免拨杆202的外螺纹与第二透镜座190的内螺纹之间配合出现松动的情况，进而可有效保障并提高第二透镜42的轴向位置的调节精度，可有效保障并提高红点瞄准镜的使用精度。
请参阅图11、图12，在本实施例中，光源件30的周侧凸设有第二球头33，第一腔11的腔壁凹设有第二球窝114，第二球头33铰接于第二球窝114，红点瞄准镜还包括设于光源件30靠近目方的一端的第二调节机构220，第二调节机构220用于带动光源件30转动。
在此需要说明的是，光源件30的第二球头33铰接于第二球窝114且被限制脱离第二球窝114，基于此，在光源件30的端部受力时，光源件30即可绕第二球头33进行一定幅度的平稳、可靠的转动。
第二调节机构220穿设安装于镜座10并设置在光源件30靠近目方的一端，可用于对光源件30靠近目方的一端施加作用力，以带动光源件30绕第二球头33进行可控幅度的转动，基于此，即可便捷、可控地实现将光源件30的光轴调节至与准直镜组40的光轴对准，进而可有效消除组装误差，可有效保障并提高红点瞄准镜的瞄准点的位置精度，可有效保障并提高瞄准精准度。
其中，第二调节机构220包括第二弹道调节钉221和第二风偏调节钉222，第二弹道调节钉221设于光源件30沿竖直方向上的一侧，可用于对光源件30靠近目方的一端施加竖直方向的作用力，以实现光源件30尤其光源件30的光轴在竖直方向的位移调节；第二风偏调节钉222设于光源件30沿水平方向上的一侧，可用于对光源件30靠近目方的一端施加水平作用力，以实现光源件30尤其光源件30的光轴在水平方向的位移调节。基于此，第二调节机构220即可快速、便捷地实现将光源件30的光轴调节至与准直镜组40的光轴对准。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换或改进等，均应包含在本申请的保护范围之内。
