[0023] The present invention provides a pet safety hook, as Figures 1-4 shown, including a pet hook 1. The upper end of the pet hook 1 is connected to a collar, and the lower end is connected to a dog leash. One side of the pet hook 1 is hinged with a locking pin 2. An outer sleeve of the locking pin 2 is provided with a safety sleeve 3. The bottom end of the locking pin 2 is riveted to the lower part of the pet hook 1. A hook groove 24 is arranged at the top end of the locking pin 2. The hook groove 24 is clamped and matched with the upper hook 11 of the pet hook 1. A card entrance 31 is arranged on one side of the top of the safety sleeve 3. The safety sleeve 3 rotates to align or stagger the card entrance 31 with the hook groove 24, so as to lock or unlock the hook 11, thus ensuring that the dog leash will not fall off accidentally.

[0024] In this embodiment, an installation groove 12 is arranged near the lower end of the locking pin 2 on the pet hook 1. A pin 13 is installed on the side wall of the installation groove 12. The pin 13 is rotationally connected to the bottom ends of the pet hook 1 and the locking pin 2, which is convenient for the locking pin 2 to turn outwards or inwards to lock or unlock the hook groove 24 and the hook 11.

[0025] Specifically, a return spring 14 is horizontally arranged inside the installation groove 12. One end of the return spring 14 is fixed in position with the inner wall of the installation groove 12, and the other end of the return spring 14 is fixed in position with the outer wall of the locking pin 2. The return spring 14 pushes the locking pin 2 outwards, so that the hook groove 24 and the hook 11 are tightly clamped and matched. By pressing the locking pin 2 inwards, the hook 11 is separated from the hook groove 24 to realize the unlocking operation. At this time, the return spring 14 contracts and stores energy. After releasing the hand, the return spring 14 acts on the locking pin 2 to make it reset.

[0026] Further, a steel ball groove 21 is provided on the outer wall of one side of the locking pin 2. A pressing spring 22 is arranged in the steel ball groove 21. A steel ball 23 is arranged at the outer end of the pressing spring 22. First clamping grooves 33 and second clamping grooves 34 are arranged on the inner wall of the safety sleeve 3. The card entrance 31 and the hook groove 24 can be aligned or staggered. By rotating the safety sleeve 3, the outside of the hook groove 24 can be closed and opened. After the hook 11 is snapped into the hook groove 24, the hook 11 can be insured to prevent it from slipping off.

[0027] Further, the hook 11 is of an L-shaped structure, and the shape of the hook groove 24 is adapted to the shape of the hook 11, which is convenient for the hook 11 to be accurately snapped into the hook groove 24.

[0028] Further, a sliding groove 32 is arranged on one side of the bottom of the safety sleeve 3. A convex block 25 is installed on the outer wall of the locking pin 2 close to the sliding groove 32. The convex block 25 is slidably matched with the sliding groove 32, so that the rotation range of the safety sleeve 3 meets the alignment or staggering of the card entrance 31 and the hook groove 24, and it will not rotate excessively.

[0029] Further, the width dimension of the card entrance 31 is larger than the width dimension of the hook groove 24, which is convenient for the hook 11 to be smoothly snapped in.

[0030] Further, a plurality of anti-slip protrusions are arranged on the outer wall of the lower part of the pet hook 1, which has a good anti-slip effect during installation.

[0031] When the pet safety hook of the present utility model is in use, first, one side of the pet hook 1 is hinged with a locking pin 2, and a safety sleeve 3 is sleeved outside the locking pin 2. The bottom end of the locking pin 2 is rotationally connected to the installation groove 12 at the lower part of the pet hook 1 through a pin 13, so that the locking pin 2 can be turned outwards or inwards. A hook groove 24 is arranged at the top end of the locking pin 2 for snap-fitting with the hook 11 at the upper part of the pet hook 1.

[0032] When it is necessary to lock the pet safety hook, by rotating the safety sleeve 3, the card entrance 31 and the hook groove 24 are aligned. At this time, the steel ball 23 on the outer wall of one side of the locking pin 2 is snapped into the first clamping groove 33 on the inner wall of the safety sleeve 3 under the action of the pressing spring 22, and then the hook 11 is snapped into the hook groove 24. At this time, the return spring 14 pushes the locking pin 2 outwards, so that the hook groove 24 and the hook 11 are tightly snap-fitted. Then rotate the safety sleeve 3 to stagger the card entrance 31 and the hook groove 24. At this time, the steel ball 23 on the outer wall of one side of the locking pin 2 is snapped into the second clamping groove 34 on the inner wall of the safety sleeve 3 under the action of the pressing spring 22, realizing the closure of the outside of the hook groove 24, and playing an insurance effect on the hook 11 to prevent it from slipping off.

[0033] When it is necessary to unlock the pet safety hook, first rotate the safety sleeve 3 so that the card entrance 31 is aligned with the hook slot 24. At this time, the steel ball 23 on the outer wall of one side of the locking pin 2 is snapped into the first card slot 33 on the inner wall of the safety sleeve 3 under the action of the pressing spring 22. Then press the locking pin 2 inward to overcome the elastic force of the return spring 14, so that the hook 11 is disengaged from the hook slot 24, and the dog leash can be unlocked. At this time, the return spring 14 contracts and stores energy. After releasing the hand, the return spring 14 acts on the locking pin 2 to reset it, preparing for the next locking.

[0034] During the whole working process, the sliding groove 32 at the bottom of the safety sleeve 3 and the convex block 25 on the outer wall of the locking pin 2 are in sliding fit, ensuring that the rotation range of the safety sleeve 3 meets the alignment or misalignment of the card entrance 31 and the hook slot 24. At the same time, the width dimension of the card entrance 31 is larger than the width dimension of the hook slot 24, facilitating the smooth snapping of the hook 11. In addition, the anti-slip protrusions at the lower part of the pet hook 1 have a good anti-slip effect during installation, improving the stability and safety of use.
