Ring clamp

摘要

A novel ring clamp, which comprises a housing, an articulated plate, rings, a handle and a slide plate, wherein the handle or the slide plate is provided with an idle stroke section, so that the slide plate does not slide towards a locking position along with the closing of the handle in the initial phase of the closing of the ring clamp; the articulated plate can cross a coplanar position along with the closing of the handle so as to close the clamp; the ring clamp is provided with a magnetic structure; and after the articulated plate crosses the coplanar position along with the closing of the handle so as to close the clamp, the slide plate is adsorbed to the locking position by the magnetic force, so that the articulated plate can be locked.

1. A novel ring clamp, comprising:
a housing; an articulated plate, in which the articulated plate consists of a first articulated plate and a second articulated plate which are articulated with each other; an articulated axis is disposed in the middle of the articulated plate; the first articulated plate and the second articulated plate are pivoted relative to the articulated axis; and both sides of the articulated plate are connected with the housing; at least two rings, in which each ring consists of a first ring member and a second ring member; the first ring member and/or the second ring member are/is connected with the articulated plate; when the articulated plate is pivoted, the first ring member and the second ring member are opened or closed along with the pivoting of the articulated plate; and after the articulated plate is pivoted towards the outside of the housing and crosses a coplanar position, the first ring member and the second ring member are closed to form a ring; a handle, in which the handle is connected with the housing and can drive the pivoting of the articulated plate; and a slide plate, in which the slide plate is arranged between the housing and the articulated plate, is connected with the handle, and can move relative to the housing; a locking position is disposed on a movement locus; when the ring clamp is in the closed state, the slide plate moves to the locking position and abuts against the articulated plate so as to lock the articulated plate; and the slide plate can be departed from the locking position along with the pulling of the handle, so that the articulated plate can be driven to rotate by the handle; wherein the handle or the slide plate is provided with an idle stroke section, so that the slide plate does not slide towards the locking position along with the closing of the handle in the initial phase of the closing of the ring clamp; the ring clamp is provided with a magnetic structure; and after the articulated plate crosses the coplanar position along with the closing of the handle, the slide plate is adsorbed to the locking position by the magnetic force generated by the magnetic structure, so that the articulated plate can be locked.
