Spherical support with additional anti-drawing function
The invention provides a spherical support with an additional anti-drawing function. The spherical support comprises an upper support plate, a sliding plate, a piston and a lower support plate, wherein the piston and the lower support plate are matched with each other; a concave spherical surface and a convex spherical surface are arranged at the two ends of the piston respectively, a second middle seat plate is placed in the concave spherical surface, and a first middle seat plate is placed on the convex spherical surface; the second middle seat plate is located between the piston and the lower support plate. The second middle seat plate and the first middle seat plate are spherical surfaces with the same arc direction. The problems existing in two existing technical schemes in the background technology are ingeniously solved, including the defects that the structural size of the first technical scheme is too large, and the second technical scheme is difficult to assemble, complex in structure and prone to loosening.
本发明提供了一种附加抗拉拔功能的球型支座，该支座包括上支座板、滑动板及相互配合的活塞和下支座板；所述活塞的两端分别开有一个凹球面和一个凸球面，所述凹球面内放置有中座板二，所述凸球面上放置有中座板一；所述中座板二位于所述活塞与下支座板之间；所述中座板二和中座板一为圆弧方向同向的球面。本发明巧妙地克服了背景技术中所述的现有两种技术方案中存在的问题，包括技术方案一的结构尺寸偏大，以及技术方案二的组装困难、结构复杂、易松动的缺点。
