Annular concave-convex clamp

Abstract

The invention relates to an annular concave-convex clamp belonging to articles for daily use. Because the upper clamp and the lower clamp of the existing annular clamp are not provided with structures for preventing the upper clamp and the lower clamp from moving left and right, so that the upper clamp and the lower clamp can move left and right sometimes and the clamped objects fall off, thereby bring loss to people. The annular concave-convex clamp of the invention consists of an annular clamp body (8), an upper clamp and a lower clamp, wherein the upper clamp and the lower clamp are arranged on the annular clamp body (8); the upper clamp is provided with a rectangular lug (1), a lug (3) and a groove (6); the lower clamp is provided with a rectangular lug (5), a rectangular lug (7), a rectangular groove (2) and a groove (4); the rectangular lug (1) and the lug (3) are matched with the rectangular groove (2) and the groove (4); and the rectangular lug (5) and the rectangular lug (7) are matched with the groove (6). The invention has the advantages of improvement on security of the annular clamp, simple structure, convenient use, easy production and low cost.

Description

Technical field [0001] The invention belongs to daily necessities, specifically a ring-shaped concave-convex clip. Background technique [0002] The ring clip is widely used on key rings, clothespins, and straps because of its convenient use. The existing ring clamp is composed of a ring clamp body and an upper card and a lower card arranged on the ring clamp body. The upper card and the lower card are generally inclined planes or planes with right angles, and mutually define positions to make the clamp clamp. However, this kind of clip, because the upper card and the lower card do not have a structural setting that restricts the left and right movement, the upper card and the lower card sometimes move left and right, causing the clamped objects such as belts, key rings, clothespins, etc. to fall off, giving people a loss . Therefore, it is necessary to invent an annular concave-convex clamp that can limit the left and right movement of the upper and lower cards and ensure the ...
