DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The following combination Figure 1-Figure 5 The rotatable and lockable hardware hook of the present invention is described in detail:

[0021] A rotatable and lockable hardware hook comprises a hook body 1 and a movable fastener 2. A notch 4 is provided on the hook body 1. One end of the movable fastener 2 is connected to the hook body 1 through a hinge 3. The movable fastener 2 can be flipped relative to the hook body 1 with the hinge 3 as the axis. The movable fastener 2 can close the notch 4 on the hook body 1. A torsion spring 5 is provided between the movable fastener 2 and the hook body 1. The hinge 3 is provided in an active cavity 6. A limit plate 7 is provided at one end of the movable fastener 2 close to the active cavity 6. The two ends of the torsion spring 5 respectively press against the limit plate 7 and the surface and the inner wall of the active cavity 6. A connecting ring 8 is provided on the surface of the hook body 1. The connecting ring 8 is rotatably connected to the hook body 1 through a rotating shaft. The surfaces of the hook body 1 and the movable fastener 2 are both provided with an electroplated anti-rust layer.

[0022] The cross-sections of the hook body 1 and the movable fastener 2 are both circular, and a limit bayonet 16 and a movable cavity 6 are respectively provided at both ends of the notch 4. A locking sleeve 9 is provided on the surface of the movable fastener 2, and an annular groove 11 is provided on the surface of the movable fastener 2. A positioning block 10 is provided on the inner wall of the locking sleeve 9. The positioning block 10 slides with the annular groove 11. The locking sleeve 9 can rotate along the surface of the movable fastener 2. An unlocking opening 19 is provided on the side wall of the locking sleeve 9. The end of the locking sleeve 9 away from the movable fastener 2 is sleeved on the limit bayonet 16. On the surface, an unlocking groove 12 and a locking groove 13 are provided on the annular slide groove 11, and the unlocking groove 12 and the locking groove 13 are 90° apart. A return spring 14 is provided between the locking sleeve 9 and the movable fastener 2, and a limiting inclined surface 15 is provided on the surface of the limiting bayonet 16. A positioning inclined surface 17 is provided on the end of the movable fastener 2 close to the limiting bayonet 16. After the movable fastener 2 is engaged with the limiting bayonet 16, the positioning inclined surface 17 contacts the limiting inclined surface 15, and the movable fastener 2 has left and right positioning grooves 18 on one end close to the limiting bayonet 16.

[0023] The rotatable locking hardware hook of this embodiment is provided with a locking sleeve 9, and the positioning block 10 can slide in the annular slide groove 11 and be stuck in the unlocking groove 12 or the locking groove 13. When the positioning block 10 is stuck in the unlocking groove 12, the unlocking opening 19 of the locking sleeve 9 is aligned with the limiting bayonet 16. At this time, the movable fastener 2 can be flipped into the hook body 1. When flipping, the limiting bayonet 16 is separated from the movable fastener 2 from the unlocking opening 19. When the positioning block 10 is stuck in the locking groove 13, the unlocking opening 19 of the locking sleeve 9 is staggered with the limiting bayonet 16, so that the movable fastener 2 cannot be flipped into the hook body 1, thereby preventing the movable fastener 2 from being pushed open by other items and causing the items hung on the hook to fall.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
