Problems solved by technology

[0004] Since the first and second connectors 80a and 80b at the two ends of the above-mentioned safety buckle 60 cannot rotate relative to the intermediate member 70, it is relatively easy to release the buckle only when it bears a pulling force parallel to the central axis 75; The buckle 60 can only be unbuckled when it is stressed at a specific angle, so the safety is relatively low

Embodiment Construction

[0053] exist figure 2 , showing the appearance of a safety buckle 10, image 3 for its component decomposition state, Figure 4 for its planar shape, Figure 5Represent its internal shape, which can be used to illustrate the technical content of the present invention. The safety buckle 10 includes an intermediate member 20, which has a first groove 21a and a second groove 21b opposite to each other. The upper surface and the lower surface of the first groove 21a respectively have two left-right symmetry, and are in the same circular arc. The arc-shaped groove 22a on the top, the upper surface and the lower surface of the second groove 21b also have two left-right symmetrical grooves 22b on the same arc; that is to say, the first groove The inner surfaces of the cavity 21a and the second groove cavity 21b each have four arc-shaped grooves 22a and 22b. In fact, the two circular arc-shaped grooves 22a and 22b symmetrically arranged on the same upper and lower surfaces can al...

Abstract

The invention discloses a safety buckle, which comprises a middle member having two relative groove holes; the upper surface and the lower surface of each groove hole are provided with two circular arc-shaped grooves; the safety buckle comprises two connecting pieces; the front end of each connecting piece is provided with an insertion part which can be inserted into one groove hole; each of the upper surface and the lower surface of each insertion part is provided with two protrusions which can be embedded into respective grooves, so that two connecting pieces are mutually locked the middle member and can rotate relative to the middle member within the angle defined by the groove to allow the buckle to automatically release the locking by the pull force acting within the angle range to ensure safety. Moreover, the two groove holes of the middle member and the insertion parts of the two connecting pieces can exchange positions to achieve the same aim.

Description

technical field [0001] The invention relates to a safety buckle, in particular to a buckle which can automatically unlock the buckle when a force is applied within a predetermined angle range. Background technique [0002] US Patent No. 7,069,625 discloses a safety buckle. Such as figure 1 As shown, the safety buckle 60 includes an intermediate member 70 having opposite first insertion portions 71a and second insertion portions 71b, which can be respectively inserted into the first groove 81a and the second connection portion 80b of the first connection member 80a In the second groove hole 81b; Also, the upper and lower surfaces of the first insertion portion 71a and the second insertion portion 71b respectively have two protrusions 72a and 72b, and the inner surfaces of the first groove hole 81a and the second groove hole 81b are provided with There are grooves 82a and 82b, allowing a pair of corresponding protrusions 72a and 72b to be embedded, thus forming a plurality o...
