Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.

As shown in fig. 1 and 2: the high-strength hoop comprises a hoop sleeve and a connecting piece connected to an opening of the hoop sleeve; the clamp sleeve comprises a sleeve ring 1 with a groove-shaped cross section and two connecting plates 6 located at the position, extending out of the opening, of the sleeve ring 1, wherein the groove opening of the sleeve ring is inward, the two connecting plates 6 are parallel and opposite and are provided with connecting holes 5 for installing connecting pieces, and the sleeve ring 1 and the two connecting plates 6 are integrally formed and are made by stamping and bending plates.

In this embodiment, the cross section of the lantern ring 1 is a trapezoidal groove with a notch wider than the bottom of the groove, and the stability is good.

In this embodiment, the both sides border of the lantern ring 1 is equipped with a plurality of evenly distributed's opening 2 respectively, can be at the crooked in-process stress relief of lantern ring 1, makes the lantern ring 1 produce the reducing ability of certain degree simultaneously.

In this embodiment, the width of two connecting plates 6 is unanimous with the notch width of lantern ring 1, and two connecting plates 6 are the cell type and the notch is relative, adds man-hour earlier with two 6 stamping forming of connecting plates, and the inside punching press bending in both sides limit portion and the outer end limit portion of connecting plate 6 forms the cell type structure, then carries out punching press and bending to lantern ring 1, and overall structure intensity is higher, and connecting plate 6 non-deformable does benefit to stable connection. As shown in fig. 3, in order to further enhance the fastening strength of the clamp, the outer ends of the two connecting plates 6 are located close to each other to form an outwardly extending abutting convex edge 61, the two abutting convex edges 61 are oppositely arranged, and the width of the abutting convex edge 61 is not less than two thirds of the width of the connecting plate 6, so that when the two connecting plates 6 are locked by the connecting piece, the two abutting convex edges 61 abut together to form an effective support of the outer ends, thereby facilitating reliable locking. The abutting convex edge 61 is a long strip shape arranged along the width direction of the connecting plate 6 and is formed by punching.

In this embodiment, the connecting piece includes bolt 7 and nut 3, the inner of nut 3 is fixed with two card ears 4 that the symmetry set up to through two 4 joints of card ear in the connecting hole 5 departments of corresponding connecting plate 6, this connecting hole 5 be with two card ear 4's position assorted slot holes, the tip of two card ears 4 all is equipped with the boss that is used for the joint location, install back nut 3 and can fix a position in slot hole department, and can not drop, insert bolt 7 during the equipment then screw up can, convenient operation. Preferably, the bolts 7 are flange bolts.
