Abstract

The invention discloses a flange type connector for engineering machinery. The flange type connector comprises a top plate, a compression spring, C-shaped springs, a nut body and an outer barrel, wherein the outer barrel is provided with a first through hole, a transition hole and a second through hole from top to bottom in a sequence; the inner diameter of the first through hole is larger than that of the second through hole; the transition hole is in an inverted cone frustum shape; a main threaded hole is formed in the axis of the nut body; the nut body is located in the first through hole;the lower portion side wall, in the first through hole, of the nut body is matched with the side wall of the transition hole; a circle of mounting groove is formed in the side wall of the nut body; aplurality of C-shaped springs are mounted in the mounting groove; and the top plate is fixed to the top end of the outer barrel. According to the flange type connector, arc-shaped pieces are combinedinto the nut body, and the connector is convenient to mount and not prone to loosening through cooperation of the C-shaped springs and the compression spring.

Description

【Technical field】 [0001] The invention relates to the technical field of joints, especially the technical field of flanged joints. 【Background technique】 [0002] The joint is a commonly used pipe connection part, which is widely used and has many types. Among them, the flange joint is a commonly used joint in construction machinery. The connection effect of the existing flange joint is not ideal enough, and it is easy to loosen. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a flanged joint for engineering machinery, which can make the joint firmly fixed and is easy to use. [0004] In order to achieve the above object, the present invention proposes a flanged joint for construction machinery, which includes a top plate, a compression spring, a C-shaped spring, a nut body, and an outer cylinder. Hole, transition hole, second through hole, the inner diameter of the first through hole is larger ...
