在安装座基板11上位于导向槽211的下方还设置有与导向槽211连通的卡槽111，销轴凸台33卡合在卡槽111内。The mounting base 11 is further provided with a clamping groove 111 which is located below the guiding groove 211 and communicated with the guiding groove 211 , and the pin shaft boss 33 is engaged in the clamping groove 111 .
装配时，将销轴3的销轴凸台33插入在连接管21的导向槽211内，并沿着导向槽211向下滑动，当滑动到安装座基板11上的卡槽111内时，将销轴3转动一定角度，从而将销轴3卡接固定，再加上压簧4的预紧力，使得销轴3不会轴向窜动。During assembly, insert the pin boss 33 of the pin 3 into the guide groove 211 of the connecting tube 21, and slide down along the guide groove 211. When sliding into the slot 111 on the mounting base The pin shaft 3 is rotated at a certain angle, so that the pin shaft 3 is clamped and fixed, and the pre-tightening force of the compression spring 4 is added, so that the pin shaft 3 will not move axially.
在销轴3的中部还设置有导向凸台34，其与导向槽211配合，在销轴3沿着轴向向下滑动安装或轴向向上移动取出时，起到导向作用。A guide boss 34 is also provided in the middle of the pin shaft 3, which cooperates with the guide groove 211, and plays a guiding role when the pin shaft 3 is slid downward in the axial direction to be installed or moved upward in the axial direction.
较佳地，如图3和图8所示，在销轴3的顶端上设置有一圈止挡边31。Preferably, as shown in FIG. 3 and FIG. 8 , a ring of stop edges 31 is provided on the top end of the pin shaft 3 .
压簧4的上端位于止挡边41的下方，在止挡边31设置有至少一个缺口部311。The upper end of the compression spring 4 is located below the stop edge 41 , and at least one notch portion 311 is provided on the stop edge 31 .
通过止挡边31限制压簧4的上端，避免压簧4脱离销轴3，也可以避免压簧4自动上蹿。在止挡边31设置的缺口部311，可以将扳手插入缺口部311内转动销轴3，使销轴3安装在安装座基板11上，方便组装。The upper end of the compression spring 4 is restricted by the stop edge 31 to prevent the compression spring 4 from being separated from the pin shaft 3 and also to prevent the compression spring 4 from jumping up automatically. In the notch portion 311 provided on the stop edge 31, a wrench can be inserted into the notch portion 311 to rotate the pin shaft 3, so that the pin shaft 3 is mounted on the base plate 11 of the mounting seat, which facilitates assembly.
较佳地，如图3和图8所示，在销轴3上还设置有压簧限位板32。Preferably, as shown in FIG. 3 and FIG. 8 , a compression spring limiting plate 32 is further provided on the pin shaft 3 .
压簧限位板32的上端与止挡边31连接，其下端朝向安装座基板11侧延伸。The upper end of the compression spring limiting plate 32 is connected with the stop edge 31 , and the lower end thereof extends toward the side of the mounting base substrate 11 .
其中，在沿着从安装座基板11至止挡边31的方向上，压簧限位板32距离销轴3的中心轴的距离逐渐变大。Wherein, along the direction from the mounting base 11 to the stop edge 31 , the distance between the compression spring limiting plate 32 and the central axis of the pin shaft 3 gradually increases.
压簧4的上端至少部分套在压簧限位板42上。The upper end of the compression spring 4 is at least partially sleeved on the compression spring limiting plate 42 .
如此设置，在内侧凸缘213与止挡边31之间的距离发生变化时，压簧4可以在压簧限位板32上做相应的上下移动以自动调节，方便组装。In this way, when the distance between the inner flange 213 and the stop edge 31 changes, the compression spring 4 can move up and down correspondingly on the compression spring limiting plate 32 to automatically adjust, which is convenient for assembly.
综上所述，本实用新型提供的汽车后视镜，可以通过转动的方式使得连接筒卡接部与基座卡接部配合和分离，进而调整镜头在安装座上转动及定位，以实现镜头转动调节视野角度与镜片调节视野角度的功能结合，扩宽了通过外后视镜观察后方视野的可调节范围，可以提高驾驶安全性。To sum up, the car rearview mirror provided by the utility model can make the connecting cylinder clamping part and the base clamping part cooperate and separate by rotating, and then adjust the rotation and positioning of the lens on the mounting seat, so as to realize the lens The combination of the function of adjusting the viewing angle by turning and adjusting the viewing angle of the lens widens the adjustable range of viewing the rear vision through the exterior rearview mirror, which can improve driving safety.
根据需要，可以将上述各技术方案进行结合，以达到最佳技术效果。According to needs, the above technical solutions can be combined to achieve the best technical effect.
