组装时，可以同时向多个注胶孔124内注入胶水，以提高组装效率，并保证每一形成第一容胶槽123的凹槽内均填充有胶水。当然，注胶孔124的数量也可以只有一个。此时，胶水由注胶孔124注入，并由与注胶孔124对应的凹槽流入至第二容胶槽340内。当第二容胶槽340填充满胶水后，胶水能够填充至其余的凹槽内，且多余的胶水能够容纳在注胶孔124内。
可以理解地，在其他实施例中，也可以是第一容胶槽123为环形槽，第二容胶槽340为环绕光轴400设置的多个凹槽。或者，第一容胶槽123及第二容胶槽340均为绕光轴400间隔设置的多个凹槽。此时，形成第一容胶槽123的凹槽的数量与形成第二容胶槽340的凹槽的数量相同，每一形成第一容胶槽123的凹槽对应于每一形成第二容胶槽340的凹槽。而且，注胶孔124也需设有多个，且注胶孔124的数量与形成第一容胶槽123的凹槽的数量相同，每一注胶孔124对应于每一形成第一容胶槽123的凹槽。组装时，多个注胶孔124内均需要注入胶水，胶水由注胶孔124流入至形成第一容胶槽123的凹槽及形成第二容胶槽340的凹槽内，以将压环300与镜筒100通过胶水连接。
进一步地，在本实施例中，主要参考图6，第一容胶槽123包括沿物侧至像侧的方向顺次连接的第一连接面1231、第一底面1232及第二连接面1233，第一连接面1231及第二连接面1233均与内表面121连接。在物侧至像侧的方向上，第一连接面1231向远离光轴400的方向倾斜，第二连接面1233向靠近光轴400的方向倾斜。
如图4所示，第二容胶槽340包括沿物侧至像侧的方向顺次连接的第三连接面341、第二底面342及第四连接面343，且第三连接面341及第四连接面343均与外侧面310连接。在物侧至像侧的方向上，第三连接面341向靠近光轴400的方向倾斜，第四连接面343向远离光轴400的方向倾斜。即，第一容胶槽123的入口处的尺寸最大，第二容胶槽340的出口处的尺寸最大，以使得注胶孔124内的胶水能够快速填充至第一容胶槽123及第二容胶槽340内。而且，第一连接面1231及第二连接面1233倾斜设置既可以保证胶水与第一容胶槽123的接触面积，又可以保证镜筒100的强度，防止镜筒100为增加第一容胶槽123与胶水的接触面积而使得镜筒100在第一容胶槽123的位置处的强度减弱。同样地，第三连接面341及第四连接面343倾斜设置也既可以保证胶水与第二容胶槽340的接触面积，又可以保证压环300的强度。
可以理解地，在其他实施例中，也可以取消第一底面1232及第二底面342。此时，第一连接面1231直接与第二连接面1233连接，第三连接面341直接与第四连接面343连接，第一容胶槽123及第二容胶槽340均为三角形凹槽。
值得一提的是，主要参考图4及图6，第一连接面1231与第一底面1232的连接处、第二连接面1233与第一底面1232的连接处、第三连接面341与第二底面342的连接处、第四连接面343与第二底面342的连接处、以及注胶孔124与第二容胶槽340的连接处均为弧形结构，避免应力集中而影响镜筒100及压环300的强度。
此外，在本实施例中，注胶孔124的轴线为直线，以减小加工难度。而且，在物侧至像侧的方向上，注胶孔124的轴线向远离光轴400的方向倾斜。这样，注胶孔124的内壁与筒壁120的内表面121之间的结构的厚度在物侧至像侧的方向上逐渐变厚，可以保证筒壁120的强度，还可以延长注胶孔124的轴线的长度，以增加注胶孔124的容积，确保多余的胶水不会从注胶孔124内溢出。
在本实施例中，注胶孔124为圆孔，在其他实施例中，注胶孔124的横截面也可以是其他形状，且注胶孔124的轴线也可以为非直线型。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
