Abstract

A swivel snaphook has a hook and a retainer. The retainer has a support portion and a strap mounting portion. The support portion has a base body connected to the strap mounting portion, a through hole passing through the base body, and a snap-in portion protruding from the surface of the base body and surrounding the through hole. The hook has a hook and connector portion and an engaging portion. The engaging portion has a connecting shaft connected to the hook and connector portion, and a snap-on portion. When the hook and the retainer are snap-fitted together, the snap-on portion surrounds the snap-in portion and fits with the snap-in portion in an inverted manner.

First claim

The invention claimed is:

1. A swivel snaphook, comprising:
a hook comprising a hook and connector portion configured for hooking an object or connecting a fabric strap, and an engaging portion connected to the hook and connector portion, the engaging portion comprising a connecting shaft connected to the hook and connector portion, and a snap-on portion; and
a retainer configured to be snap-fitted together with the hook, the retainer comprising a support portion and a strap mounting portion configured to connect a fabric strap, the support portion comprising a base body connected to the strap mounting portion, a through hole passing through the base body, and a snap-in portion protruding from a surface of the base body and surrounding the through hole;
wherein the snap-on portion surrounds the snap-in portion and is snap-fitted with the snap-in portion, and wherein the connecting shaft is rotatably inserted in the through hole,
wherein the snap-in portion comprises a raised ring protruding from the surface of the base body, and a snapping boss extending outward from a tail end of the raised ring; the snap-on portion comprises a plurality of bosses arranged surrounding the connecting shaft in a centrosymmetric manner; and
when the hook and the retainer are snap-fitted, the plurality of bosses and the snapping boss abut against each other, such that the snap-in portion and the snap-on portion are snap-fitted together in an inverted manner.

2. The swivel snaphook according to claim 1 , wherein the snap-in portion further comprises a plurality of notches recessed from an end surface of the raised ring.

3. The swivel snaphook according to claim 1 , wherein
each boss of the plurality of bosses has an inner side surface forming an acute angle with respect to a vertical plane;
the snapping boss has a smooth arc-shaped surface connected to the raised ring, and an abutting surface extending from an end of the arc-shaped surface; and

when the hook and the retainer are snap-fitted, the inner side surface abuts against the abutting surface.

4. The swivel snaphook according to claim 1 , wherein the plurality of bosses of the snap-on portion comprises two bosses configured opposite each other, and wherein a width of the two bosses is greater than a radial width of the connecting shaft.

5. The swivel snaphook according to claim 1 , wherein the plurality of bosses are joined to each other to form an annular boss.

6. The swivel snaphook according to claim 1 , wherein each boss of the plurality of bosses has a protrusion protruding from a surface of the each boss that faces the connecting shaft; and when the hook and the retainer are snap-fitted, the protrusion is snap-fitted with the snapping boss.

7. The swivel snaphook according to claim 1 , wherein the hook and connector portion comprises a D-shaped ring body.

8. The swivel snaphook according to claim 1 , wherein the hook and connector portion comprises a hook body in a shape of a curved hook.
