The utility model discloses a fixed structure with the adjustment of the radial dimension and rotation angle of the blade. A connecting part is arranged at the lower part of the blade. The connecting part comprises an upper convex ring and a lower convex ring, and the shaft shank is between the upper convex ring and the lower convex ring. Corresponding grooves are arranged, the lower convex ring is fastened by the groove of the cover and the hub, and the cover is fixed on the hub by bolts; long grooves corresponding to the shaft shank are arranged on the hub and the cover; cams are arranged on the lateral axis of the shaft shank; and grooves are arranged along the radial direction on the hub and the cover. The utility model has the advantages that: since a plurality of grooves are arranged along the radial direction corresponding to the convex ring, the structure can be adjusted radially according to the needs; and the convex ribs of the shaft handle are corresponding to the convex ribs of the long groove, which can limit the rotation of the blade after the blade angle is fixed and the rotation angle of the blade can be arbitrary. Set up to meet various needs.
【技术实现步骤摘要】
一种具有叶片径向尺寸及转动角度调节的固定结构
本技术涉及叶片,具体说是一种叶片与轮毂的固定结构。
技术介绍
叶片是常用的机械部件。在使用时,有时需要对叶片的转动角度及长度进行调整,以便改变排风量或与排风通道的内径吻合。现有的叶片均为固定结构的,尤其是叶片的径向长度都是固定的,这就无法实现调整功能。
技术实现思路
为了解决上述技术问题,本技术的目的是提供一种具有叶片径向尺寸及转动角度调节的固定结构,叶片的下方设置连接部,所述连接部包括上凸环及下凸环,上凸环和下凸环间为轴柄;所述上凸环嵌入叶片内,所述下凸环设置在轮毂的对应凹槽内;轮盖也设置相应的凹槽,轮盖与轮毂的凹槽对应将所述下凸环扣紧,轮盖通过螺栓固定在轮毂上;轮毂与轮盖上均设置与轴柄对应的长条凹槽;所述轴柄的外侧轴向上设置凸筋;所述轮毂和轮盖上沿径向设置多组凹槽。另外的一种轮毂结构是:所述轮毂为两组同心圆结构,外侧的轮毂设置与轴柄对应的长条凹槽,内侧轮毂上设置与下凸环对应的凹槽。为保证叶片调整角度后的固定,所述长条凹槽的内侧设置凸筋。这样,长条凹槽与轴柄接触后,由于凸筋的限制,叶片的转动角度不会发生变化。本技术中,叶片的 ...
