相关申请的交叉引用
本申请要求于2022年01月26日提交中国国家知识产权局的申请号为202220219559.3、名称为“X射线球管安装结构、机盒和牙科X射线机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及X射线技术领域，尤其是涉及一种X射线球管安装结构、机盒和牙科X射线机。
背景技术
牙科X射线机是口腔治疗中广泛应用的影像学检查，主要功能是拍摄单颗牙齿的X光片，也叫口内X线成像设备，单次曝光可拍摄门齿或犬齿的X线影像。
X射线球管是牙科X射线机的关键部件，其通常包括同轴设置的玻璃壳(管壳)、灯丝(阴极)和靶材柱(阳极)，灯丝发射的电子撞击到阳极的靶面后即可产生X射线。
由于阳极的靶面与自身轴线呈一定角度，X射线是呈与阳极轴线以一定角度向外发射，球管的位置精度对球管发出的X射线角度有很大影响。对于X射线球管，当前市场上普遍使用直套筒加点胶的方式对球管进行保护固定。这种方式虽然能防止球管转动，但在装配时，球管的位置需要人为不断的对齐调试，直到位置正确再进行点胶。这样不但安装操作繁琐复杂，定位精度也无法保证。

下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参考图1至图4，本申请实施例提供了一种机盒，该机盒包括盒体1以及X射线球管安装结构3，X射线球管安装结构3包括、接线板36、电路板38、固定板30、缓冲保护套32和X射线球管34。
固定板30和缓冲保护套32均设置于盒体1内，且固定板30与缓冲保护套32的一端以预设间隔相对布置，其中，固定板30靠近缓冲保护套32的一侧设有定位凸起301，缓冲保护套32的侧壁设有出射孔321，盒体1的侧壁设有与出射孔321对应且连通的配合口14。
X射线球管34的阳极341连接于固定板30，且有与定位凸起301相配合的定位凹陷3410，X射线球管34的管壳343同轴配合于缓冲保护套32内，以使阳极341的靶面3416与出射孔321在垂直于缓冲保护套32的轴线的方向相对，接线板36位于阳极341和固定板30之间，以连接线路，电路板38焊接于X射线球管34远离固定板30的一端，从而通 过电路板38控制X射线球管34的灯丝的通断电，以使灯丝向阳极341的靶面3416发射电子，由靶面3416产生的X射线能够从出射孔321射出，且使X射线的光轴相对于出射孔321处于确定位置。
由此，通过固定板30和缓冲保护套32以预设间隔相对布置，并在固定板30上设置定位凸起301，从而在将管壳343同轴配合于缓冲保护套32内后，使阳极341的定位凹陷3410与定位凸起301配合，再将阳极341和固定板30连接，即可限定X射线球管34的轴向位置和周向位置，实现X射线球管34的精准定位，缓冲保护套32对X射线球管34进行保护，从而使得阳极341的靶面3416与出射孔321在垂直于缓冲保护套32的轴向的方向相对，由此阳极341的靶面3416产生的X射线能够以确定的方向从出射孔321和配合口14射出，相对于现有技术而言，不再需要人为不断对其调试，只需要通过简单地将固定板30、缓冲保护套32和X射线球管34正常装配即可使X射线球管34的安装定位精度满足需求。
另外，为了进一步方便X射线球管34的轴向位置的确定，因此可以在装配过程中，将预设间隔设置为使得缓冲保护套32靠近固定板30的一端与X射线球管34的管壳343靠近固定板30的一端齐平。
在本实施例中，盒体1包括底座10和罩体12，X射线球管安装结构3设置于底座10上，罩体12与底座10连接，以将X射线球管34罩覆。
进一步的，底座10上有依次间隔设置的卡槽101和支撑部103，其中支撑部103的数量不做具体限制，一个以上均可，例如，盒体1有依次间隔设置的卡槽101和至少两个支撑部103，固定板30卡接于卡槽101，每个支撑部103具有形状与缓冲保护套32的形状相适配的支撑面1030，缓冲保护套32配合于支撑面1030，由此即可将X射线球管安装结构3设置于盒体1内。
示例性的，配合口14的两侧均有至少一个支撑部103，从而保证X射线球管34通过缓冲保护套32搁置在支撑部103的支撑面1030上有更好地稳定性。底座10上设有凸起的卡持件105，卡持件105设有一卡槽101，由此固定板30卡接于每个卡持件105的卡槽101内，以实现固定板30相对于底座10的固定。其中，卡持件105可以是至少两个，从而使得固定板30与同时与至少两个卡持件105的卡槽101卡接，以使固定板30相对于底座10更为稳定，进而保证X射线球管34相对于底座10的稳定性。
底座10的边缘还凸设有配合部107，该配合部107远离底座10的部位设有半圆形的第一凹槽1070，罩体12的一侧壁则设有半圆形的第二凹槽121，由此在底座10和罩体12连接后，第一凹槽1070和第二凹槽121共同形成配合口14。
需要说明的是，一般而言，出射孔321和配合口14同轴，且出射孔321的轴线与缓冲 保护套32的轴线相交且垂直，以更利于X射线球管34的阳极341产生的X射线射出。
另外，缓冲保护套32的外周面设有围绕于出射孔321的外周缘的凸环323，凸环323配合于配合口14，由此，在装配机盒时，可以先将固定板30、X射线球管34和缓冲保护套32设置于底座10后，再将罩体12的第二凹槽121对准第一凹槽1070，两者将凸环323包围，最后再将罩体12和底座10连接，以方便装配，同时配合口14与凸环323配合，能够使得缓冲保护套32相对于盒体1更为稳定，继而使得X射线球管34能够稳定。
示例性的，结合图3至图6，固定板30和阳极341之间为螺接，即固定板30设有连接穿孔303，阳极341用于与固定板30连接的端面设有螺纹孔3412，螺丝39穿过连接穿孔303后与螺纹孔3412螺纹连接，从而实现固定板30和阳极341之间的连接固定，从而限定X射线球管34的轴向位置。
另外，阳极341用于连接固定板30连接的端面设有定位凹陷3410，从而定位凸起301直接插接配合于定位凹陷3410，以限定X射线球管34的周向位置。其中，定位凸起301可以一体连接于固定板30的柱状凸起。定位凹陷3410则可以是设置于阳极341的端面的盲孔，定位凸起301的长度延伸方向以及定位凹陷3410的深度延伸方向均沿阳极341的轴向。
当然，需要说明的是，在一些实施例中，定位凸起301也可以是依次穿设于固定板30和定位凹陷3410的销钉，定位凹陷3410还可以是设置于阳极341的外周面，由此两者相配合也能够限制阳极341相对于固定板30的转动，进而限制X射线球管34的周向位置。
缓冲保护套32通常为具有一定弹性的橡胶材质，其与X射线球管34的管壳343之间为过盈配合，从而能够在机盒收到冲击时起到缓冲作用，以保护X射线球管34，示例性的，结合图4和图7，缓冲保护套32的内周面设有沿自身轴轴向间隔分布的第一配合组件和第二配合组件，第一配合组件包括沿缓冲保护套32的周向间隔分布的多个第一配合凸起325，第二配合组件包括沿缓冲保护套32的周向间隔分布的多个第二配合凸起327，X射线球管34的管壳343与多个第一配合凸起325和多个第二配合凸起327均过盈配合，由此即可实现X射线球管34的管壳343同轴配合于缓冲保护套32内，且保持X射线球管34与缓冲保护套32的相对固定，另外，由于多个第一配合凸起325和多个第二配合凸起327均呈缓冲保护套32的周向间隔分布，因此能够在缓冲保护套32和X射线球管34的管壳343之间形成的间隙通入冷却液，冷却液与管壳343有较大的接触面积，以在X射线球管34工作时对其进行冷却降温。
当然，为了使冷却液流经更为自由地流经缓冲保护套32和管壳343之间的间隙，因此可以将多个第一配合凸起325和多个第二配合凸起327设置为在缓冲保护套32的周向上呈 依次交替分布，从而提高了冷却效率。
其中，第一配合凸起325和第二配合凸起327的形状基本相同，均可以是半圆柱式凸起，即第一配合凸起325的表面和第二配合凸起327的表面均可以是圆柱面的一部分，且第一配合凸起325和第二配合凸起327的长度延伸方向均沿缓冲保护套32的轴向，以达到固定X射线球管34的优良作用，而且更好地保证冷却液在球管和缓冲保护套32之间的间隙内的流通。当然也可以均是球状、圆台状或其他形状的凸起，在本实施例中具体的形状并不进行限制。
X射线球管安装结构3还包括防辐射层33，防辐射层33覆盖于缓冲保护套32的外周面上除出射孔321以外的区域，因此防辐射层33的形状与缓冲保护套32的形状相适配，从而防止X射线球管34工作时的辐射泄露。示例性的，防辐射层33可以是铅皮，还可以是防辐射硅胶，硅胶里加入防辐射的氧化铋，硫酸钡，氧化锆等。
在本实施例中，阳极341的外周面设有第一定位部3414，缓冲保护套32的外周面设有第二定位部329，第一定位部3414的几何中心、第二定位部329的几何中心与阳极341的轴线均在预设平面内，且在预设平面内，第一定位部3414的几何中心和第二定位部329的几何中心均位于阳极341的轴线的同一侧。
也就是说，在将固定板30与阳极341连接固定之前，可以通过观察第一定位部3414和第二定位部329是否在阳极341的轴向上对正，若不对正可以微调X射线球管34，使得X射线球管34相对于缓冲保护套32转动，直至第一定位部3414和第二定位部329对正，再紧固固定板30和阳极341，即可进一步保证X射线球管34的安装定位精度。
为了便于观察第一定位部3414和第二定位部329是否在阳极341的轴向上对正，因此将第一定位部3414与出射孔321在垂直于缓冲保护套32的轴线的方向上相对，第二定位部329与出射孔321在缓冲保护套32的轴向上相对，靶面3416为椭圆形，靶面3416的长轴与阳极341的轴线相交，以确定预设平面，预设平面能够将出射孔321对半分割，从而可以直接从缓冲保护套32上设有出射孔321的一侧直接进行观察。
当然，可以理解的是，在一些实施例中，第一定位部3414和第二定位部329也可以是设置于其他位置，例如在在缓冲保护套32的周壁上背离出射孔321的一侧设置由弹性透明材料制成的观察区域，观察区域附近设置第二定位部329，相应的，第一定位部3414则设置于阳极341的外周面上背离出射孔321的位置。
另外，第一定位部3414和第二定位部329还可以是分别设置在阳极341以及缓冲保护套32上的球状凸点，从而可以将第一定位部3414和第二定位部329调为均在阳极341的轴向上或者完全重合即可。
由于在本实施例中，出射孔321的轴线与缓冲保护套32的轴线垂直，因此出射孔321的轴线也位于预设平面内，即阳极341的靶面3416上的X射线的射出点位于出射孔321的轴线上，进而保证X射线的光轴与出射孔321的轴线重合，以保证成像效果。
可选择的，第一定位部3414为沿阳极341的轴向延伸的第一凸条或第一切槽。第二定位部329为沿缓冲保护套32的轴向延伸的第二凸条或第二切槽。由此在装配X射线球管34时，通过出射孔321进行观察，由于第一定位部3414和第二定位部329的延伸方向均与阳极341的轴向平行，因此更利于调整X射线球管34，以使第一定位部3414和第二定位部329对齐，或者第一定位部3414和第二定位部329分别在垂直于预设平面内的参考平面内的投影有部分重叠，即可保证X球管的周向定位。
需要说明的是，在一些实施例中，第一定位部3414也可以是设于X射线球管34的管壳343的外周面。
本申请实施例还提供了一种牙科X射线机，该牙科X射线机包括如上述的机盒实施例，因此也具有相应的结构和有一效果，在此不再赘述。
综上，本申请实施例的X射线球管安装结构3、机盒和牙科X射线机，能够以结构更为简单，装配更为方便地将X射线球管34的安装定位精度满足需求。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
