Mechanism for connecting two flanged pipe ends or tube ends

Abstract

Disclosed is a mechanism for connecting free flanged pipe ends or tube ends (2, 22). Said mechanism comprises several hingedly interconnected clamp segments (3A, 3B, 3C, 3D) that have a substantially U-shaped cross-section, a clamping lever (4), one end of which is arranged at a free end of a clamp segment (3A), and at least one spring (5). The clamp segments (3A, 3B, 3C, 3D) externally overlap the flanges of the joined pipe ends or tube ends (2, 22) while the free ends of the first and the last clamp segment (3A and 3D) can be locked by means of the clamping lever (4) and the spring (5). In order to reliably prevent the closed mechanism from automatically opening under all circumstances, the clamping lever (4) can be positively connected to the free end of the adjacent clamp segment (3D)and can be locked in the tightened position.

Description

technical field

[0001] The invention relates to a device for connecting free ends of flanged pipes or hoses, the device comprising: a plurality of mutually hinged clamp segments with a substantially U-shaped cross-section; a clamping rod, the clamp The tightening rod is arranged on the free end of a clamp section with the end side; and the spring, wherein the clamp section rests on the flanges of the pipe or hose ends that are pushed together, and the first and last The free end of a clamp section can be locked by means of a clamping lever and a spring. Background technique

[0002] Various designs of such devices, referred to as pipe or hose connectors or pipe or hose clamps for short, have been known for a long time. The simplest arrangement of this type consists of a clamp with two clamp segments, which are hinged to each other at both ends by means of screws (EP 0 195 914 A2). For locking, the open clamp is placed on the flange of the pushed-together pipe ends or, corr...
