Description

Technical Field

[0001] This invention relates to the field of pet protective equipment technology, and in particular to a protective device for preventing pet cat bites. Background Technology

[0002] Cats are easy-to-care-for pets. They are relatively independent and don't require much training or space. Compared to dogs, cats typically don't need outdoor activities and are better suited to living in a home. Furthermore, cats spend a lot of time grooming themselves, rarely experiencing major cleaning problems. However, because they don't spend much time outdoors, their nails don't wear down quickly enough, leading them to scratch furniture for relief, thus requiring regular nail trimming. Unlike human nails, cats have a quick (blood vessel) in the nail area. If a cat is uncooperative, it's easy to accidentally injure it, triggering a stress response that will cause it to bite regardless of whether it's its owner or not, especially novice cat owners. Therefore, many cat owners choose to have their cat's nails trimmed at a veterinary clinic. However, cats with strong personalities may become hostile towards strangers in unfamiliar environments and won't cooperate. Even experienced veterinarians can get bitten or scratched during the process, and they are hesitant to use forceful methods for fear of injuring the cat, which also significantly slows down the entire nail trimming process, making it time-consuming and laborious. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides a protective device to prevent pet cat bites. It features a reasonable structural design and convenient operation. Through a guided fixation method, even in unfamiliar environments, strangers can effectively and naturally restrain the cat without physical contact, reducing stress responses. By effectively isolating the cat's head from its limbs, it allows ample time for people to observe the cat's nails, thus preventing accidental injury. Furthermore, the cat does not require reassurance in unfamiliar environments and will not attempt to escape, thereby speeding up the nail trimming process, saving time and effort, and solving problems encountered in practical use.

[0029] like Figure 1-9As shown, a protective device for preventing pet cat bites includes a transfer mechanism and a fixing mechanism connected to the left side of the transfer mechanism. The fixing mechanism includes a horizontally arranged fixing sleeve 1, with a head fixing member at the left end of the fixing sleeve 1. The head fixing member includes a head sleeve 2 movably fitted onto the fixing sleeve 1, and a locking mechanism on the head sleeve 2 that cooperates with the fixing sleeve 1. A flexible sleeve 3 is provided on the left side of the head sleeve 2, with the opening at the left end of the flexible sleeve 3 inclined upwards to the left. A notch 4 is provided at the top of the flexible sleeve 3, and a Velcro surface 5 is provided on the outer wall of the flexible sleeve 3 in front of the notch 4. The flexible sleeve 3 on the rear side of the opening 4 has a hook-and-loop hook surface 6 that matches the hook-and-loop hook surface 5; a sealing element is provided at the right end of the fixed sleeve 1, the sealing element includes an arc-shaped fixing block 7 that abuts against the front side wall of the fixed sleeve 1, and a number of sealing rods 8 are evenly spaced from top to bottom on the inner wall of the arc-shaped fixing block 7, each sealing rod 8 horizontally penetrating the fixed sleeve 1; an arc-shaped rubber block 9 is provided on the rear side wall of the fixed sleeve 1, and a locking hole 10 that matches each sealing rod 8 is provided on the arc-shaped rubber block 9; and leg fixing sleeves 11 that are connected to the fixed sleeve 1 are provided at the four corners of the bottom surface of the fixed sleeve 1.

[0030] Optionally, the locking mechanism includes an L-shaped groove 12 provided on the outer wall of the left end of the fixed sleeve 1. The horizontal section of the L-shaped groove 12 extends out of the left end of the fixed sleeve 1. An E-shaped groove 13 is provided on the head sleeve 2 corresponding to the position of the L-shaped groove 12, penetrating its top side wall. The three vertical sections of the E-shaped groove 13 are respectively arranged parallel to the vertical section of the L-shaped groove 12. The horizontal section of the E-shaped groove 13 coincides with the horizontal section of the L-shaped groove 12. A positioning block 14 is movably provided in the L-shaped groove 12. Its surface is provided with a sliding rod 15 that extends vertically out of the E-shaped groove 13. A sliding block 16 is provided at the outer end of the sliding rod 15. By pressing the sliding block 16, the doctor can move the sliding rod 15 and the positioning block 14. When it moves to the horizontal section of the E-shaped slot 13, the horizontal section of the E-shaped slot 13 coincides with the horizontal section of the L-shaped slot 12. Pulling the head sleeve 2 to the left will separate the head sleeve 2 from the fixing sleeve 1. The separated head sleeve 2 can be used alone and is only suitable for cats with good temperaments. The three vertical sections of the E-shaped slot 13 can be used to accommodate different neck lengths of cats. Before use, the positioning block 14 needs to be adjusted. The leftmost vertical section of the E-shaped slot 13 is suitable for cats with shorter necks, while the rightmost vertical section is suitable for cats with longer necks.

[0031] Optionally, guide grooves 17 are provided on the front and rear sides of the outer wall of the fixed sleeve 1 along the horizontal direction, and guide blocks 18 are provided on the inner wall of the head sleeve 2 corresponding to the two guide grooves 17. The head sleeve 2 is movably engaged with the fixed sleeve 1 by the two guide blocks 18 provided on its inner wall, thereby limiting the position of the head sleeve 2 and the fixed sleeve 1, keeping them unchanged, and preventing them from being misaligned or rotated.

[0032] Optionally, the two leg fixing sleeves 11 located at the right end of the fixing sleeve 1 have larger openings than the two leg fixing sleeves 11 located at the left end of the fixing sleeve 1. The two leg fixing sleeves 11 at the left end correspond to the forelimbs of the cat, and the elongated holes greatly accommodate cats of different sizes; while the two leg fixing sleeves 11 at the right end correspond to the hind limbs of the cat, allowing larger hind limbs to be inserted into the two leg fixing sleeves 11.

[0033] Optionally, the device also includes an observation window 19 on the top surface of the fixed sleeve 1. A groove 20 is provided at the right end of the fixed sleeve 1 corresponding to the observation window 19. An arc-shaped connecting plate 21 is provided on the groove 20 of the fixed sleeve 1. Several limiting rods 22 are horizontally spaced along the arc direction inside the observation window 19. The left end of each limiting rod 22 is movably engaged with the left inner wall of the observation window 19, while its right end extends horizontally through the fixed sleeve 1 and connects to the arc-shaped connecting plate 21. After the veterinarian finishes trimming the nails, they can lift the Velcro hook 6 and pull the arc-shaped connecting plate 21, causing the limiting rods 22 inserted into the observation window 19 to be pulled outwards, thereby lifting the pet cat outwards from the observation window 19 of the fixed sleeve 1.

[0034] Optionally, the transfer mechanism includes a housing 23, with an inlet 24 on the left side of the top plate of the housing 23, a groove 26 connected to the inlet 24 along the length of the top plate 25 of the housing 23, and retaining strips 27 along the length of the inner walls of the front and rear sides of the housing 23 below the top plate 25. A sealing plate 28 is provided below the top plate 25, with its bottom front and rear sides movably engaged with the retaining strips 27 on the corresponding side, and its surface movably closed on the inlet 24 of the housing 23. A push-pull handle 29 is vertically provided on the sealing plate 28 corresponding to the groove 26, passing through the groove 26. Several ventilation holes 30 are provided on the front and rear side walls of the housing 23, and a retaining pipe 31 is connected to the left side wall of the housing 23. Several retaining holes 32 that cooperate with the sealing rod 8 are horizontally provided on the retaining pipe 31 along its height.

[0035] Optionally, symmetrical U-shaped slots 33 are provided on both the front and rear sides of the top plate 25 of the box body 23 outside the entrance 24. Each U-shaped slot 33 contains a U-shaped lifting rod 34, which is movably hinged to the corresponding U-shaped slot 33 via pins 35 at its two ends. Fastening grooves 36, communicating with the corresponding U-shaped slots 33, are provided on both the front and rear sides of the top plate 25 of the box body 23. This allows people to lift the box body 23 by pulling the two U-shaped rods 34, thus moving the box body 23.

[0036] Optionally, a cushioning pad 37 is attached to the entrance 24 of the top plate 25 of the enclosure 23 to reduce the risk of the cat bumping into the entrance 24 when entering the enclosure 23.

[0037] Optionally, a connecting platform 38 is vertically provided at the center of the bottom surface of the fixed sleeve 1, and a threaded pipe 39 is vertically threaded to the bottom of the connecting platform 38. A counterweight circular plate 40 is horizontally provided below the threaded pipe 39, and a support rod 41 is vertically provided on the counterweight circular plate 40 and engaged with the threaded pipe 39. This provides support for the fixed sleeve 1, making it easier for people to trim the nails of pet cats that are suspended in the air.

[0038] Optionally, the flexible sleeve 3 is a rubber sleeve.

[0039] In use, the sealing components can be removed from the fixing sleeve 1 first, and the sealing rods 8 on the arc-shaped fixing block 7 can be inserted into the corresponding locking holes 32 on the locking tube 31. Then, the arc-shaped rubber block 9 can be used from the other side of the locking tube 31 to lock the corresponding locking holes 10 to the ends of the sealing rods 8. Next, pull the push-pull handle 29 on the sealing plate 28 by hand, so that the push-pull handle 29 moves to the right along the slide groove 26, thereby removing the sealing plate 28 that was originally closed on the entrance 24 of the box 23. Then, open the zipper of the pet carrier and align the opening of the pet carrier with the entrance 24 of the box 23, so that the pet cat can enter the box 23 smoothly. After the pet cat is completely inside the box 23, close the entrance 24 of the sealing plate 28 again. Then, take out the U-shaped lifting rods 34 from the buckle groove 36 and flip them upwards, so that the doctor can lift the box 23 with one hand.

[0040] After moving the box 23 to the operating position, the right end of the fixing sleeve 1 needs to be connected to the locking tube 31 of the box 23, and the sealing piece attached to the locking tube 31 should be removed. Using food as bait, lure the cat into the fixing sleeve 1. The cat crawls forward inside the fixing sleeve 1 until its head is inside the head sleeve 2 and protrudes outward from the outlet of the flexible sleeve 3. At this point, pull up the hook side 6 of the Velcro and pull it to adhere to the loop side 5 of the Velcro. This adjusts the opening size of the flexible sleeve 3 by adjusting the angle of the notch 4, thus securing the cat's neck and preventing its head from retracting into the fixing sleeve 1. The cat's limbs are then secured into the corresponding leg fixing sleeves 11. The sealing piece is then re-inserted into the right end of the fixing sleeve 11, and the fixing sleeve 1 is separated from the locking tube 31 of the box 23, thus securing the cat inside the fixing sleeve 1. Finally, the threaded tube 39 is connected to the bottom of the connecting platform 38 of the fixed sleeve 1 and placed on the operating surface, so that the threaded tube 39 is engaged with the support rod 41 of the counterweight circular plate 40. At this time, the nails of the pet cat's limbs can be trimmed. By rotating the fixed sleeve 1, it can be rotated along the axis of the support rod 41, thereby adjusting the angle of the pet cat and facilitating the doctor's operation. Its structure is reasonable and easy to operate. Through the guided fixation method, even in unfamiliar environments, strangers can effectively fix the pet cat naturally without touching it, reducing its stress response. By effectively isolating the cat's head from its limbs, people have enough time to observe the pet cat's nails, thus avoiding accidental injury. At the same time, the pet cat does not need to be comforted in unfamiliar environments and will not run away, thus speeding up the entire nail trimming process, saving time and effort, and solving problems existing in practical use.
