The invention discloses a bottom-plate-free connecting rod spherical hinge. The bottom-plate-free connecting rod spherical hinge comprises a ball pin base, a ball pin sleeve and a ball pin. The ball pin is arranged in a cavity in the ball pin base so that a spherical friction pair can be formed. The ball pin sleeve is arranged on the ball pin base in a sleeving manner. A flange is arranged on theouter wall of the ball pin base. A riveting edge is arranged at an end of the ball pin sleeve, and the flange is clamped between the inner wall of the ball pin sleeve and the riveting edge. A concave-convex structure is arranged on the surface of the riveting edge connected with the flange and is connected to the interior of the flange in a pressed manner. According to the spherical hinge, the flange on the ball pin base is clamped by the inner wall of the ball pin sleeve and the riveting edge on the ball pin sleeve, and therefore the ball pin base is not easily separated from the ball pin sleeve; and meanwhile, the riveting edge is provided with the concave-convex structure to be clamped and pressed on the flange of the ball pin base, and therefore, relative rotation of the ball pin sleeve and the ball pin base in a low-temperature state can be prevented.

    本发明公开了一种无底板连接杆球铰,包括球销座、球销套及球销,所述球销设于球销座内的腔体内,以构成一组球面摩擦副;所述球销套套设在球销座上,球销座外壁上设有凸缘,球销套的端部设有铆边,且凸缘卡接于球销套内壁与铆边之间;与凸缘相接的铆边的表面设有凹凸结构,所述凹凸结构压接于所述凸缘内;本发明的球铰中,球销座上的凸缘被球销套内壁和球销套上的铆边卡接,使得球销座不易脱离球销套,同时铆边上设有凹凸结构卡压在球销座的凸缘上,可防止低温状态下,球销套与球销座的相对转动。
