Description

Technical Field

[0001] The utility model relates to the technical field of pet products, in particular to a cat roller. Background Art

[0002] In the wild, cats run, climb, and hunt, but in indoor environments, cats' range of activities is often limited. When they cannot fully release their energy, cats will vent their energy by scratching and biting indoor objects. Cat rollers, also known as cat treadmills, are mainly used to provide cats with an indoor exercise environment. Cats are naturally active and they need enough exercise and play to stay healthy and energetic.

[0003] The cat roller is composed of a hollow cylinder installed on a U-shaped wheel. The cat runs on the inner wall of the hollow cylinder to make the cat roller rotate. Generally, the cylinder is placed directly on the U-shaped wheel. When the cat is running, the roller continues to shake, resulting in poor stability. Cats are prone to lose balance or be frightened when running, increasing the risk of falling and injury or cat stress. In addition, lighter objects nearby will be drawn into the rotating cat roller. For a multi-cat household, it may cause accidental injury to other cats. Light objects drawn into the cat roller may cause blockage, affecting the normal rotation of the roller, or even causing the roller to stop rotating. If the object that enters is hard or sharp, it may damage the cat roller or other components, affecting the cat's experience and safety. Utility Model Content

[0004] The purpose of the utility model is to provide a cat roller to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The guide bar is installed on the rotating wheel, and the inner wall of the fixed wheel is provided with a guide rail matching with the guide bar.

[0009] Preferably, the guide rail is provided on the inner wall of the fixed wheel, the side plates are symmetrically arranged on both sides of the fixed wheel, and the guide strip is arranged on the outer surface of the rotating wheel.

[0010] Preferably, the outer wall diameter of the rotating wheel is matched with the inner wall diameter of the fixed wheel, and the guide rails and guide strips are symmetrically arranged and have matched sizes.

[0011] Preferably, grooves are symmetrically arranged through the lower portion of the fixing wheel, and connecting plates are symmetrically arranged below the grooves.

[0012] Preferably, the connection plate is fixedly connected to the connection point of the rotating wheel, the rotating wheel is located in the groove, and the middle bending part of the rotating wheel is in contact with the guide strip on the outer surface of the rotating wheel.

[0013] Preferably, a threaded rod is connected through the middle of the connecting plate.

[0014] Preferably, a clamping block is provided on one side of the threaded rod close to the rotating wheel, and the outer surface of the clamping block is an inclined conical shape.

[0015] Preferably, a slot is provided in the middle of the outer surface of the rotating wheel, and the side walls of the slot are symmetrically inclined.

[0016] Preferably, the card slot is adapted to the size of the card block.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] By setting guide rails and guide strips on the fixed wheels and the rotating wheels, the stability of the cat roller is increased, the movement direction of the cat roller can be effectively guided, the shaking and swaying of the roller can be reduced, and the comfort and stability of the cat when walking on it can be improved. The stable cat roller can reduce the risk of accidental falls or unstable rolling, protect the safety of the cat and avoid injuries.

[0019] By setting up fixed wheels, stability is ensured while preventing foreign objects from getting stuck in the cat roller, maintaining the normal operation of the cat roller, improving the safety of the cat roller, and protecting the cat from accidental injuries. A stable cat roller without foreign object interference can improve the cat's exercise experience and increase the fun of the cat playing on it.

[0020] By inserting the block on the threaded rod into the slot of the rotating wheel, the cat roller can be prevented from being used by the pet at night or when no one is watching over it, which can reduce the risk of accidents. Limiting its use can maintain a quiet environment, which helps both the owner and the pet to get a good rest. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the above terms should not be understood as limitations on the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0031] Example:

[0032] See also Figure 1-Figure 4The cat roller comprises two side panels 1, and a fixed wheel 2 arranged on the side panel 1, a rotating wheel 3 is arranged inside the fixed wheel 2, and a rotating wheel 401 which rotates with the rotating wheel 3 is arranged below the rotating wheel 3; it also comprises a guide bar 301 which is installed on the rotating wheel 3, and a guide rail 201 which cooperates with the guide bar 301 is arranged on the inner wall of the fixed wheel 2. The guide rail 201 and the guide bar 301 are arranged on the fixed wheel 2 and the rotating wheel 3 to increase the stability of the cat roller, effectively guide the movement direction of the cat roller, reduce the shaking and swaying of the roller, and improve the comfort and stability of the cat when walking on it. The fixed wheel 2 arranged on the outer surface of the rotating wheel 3 ensures stability while preventing foreign objects from getting stuck in the cat roller, thereby maintaining the normal operation of the cat roller.

[0033] Among them, the guide rail 201 is opened on the inner wall of the fixed wheel 2, the side panels 1 are symmetrically arranged on both sides of the fixed wheel 2, the guide strip 301 is arranged on the outer surface of the rotating wheel 3, the outer wall diameter of the rotating wheel 3 is adapted to the inner wall diameter of the fixed wheel 2, the guide rail 201 and the guide strip 301 are symmetrically arranged, and the sizes are adapted. By setting the two guide rails 201 and the guide strip 301, the stability of the cat roller during use is increased, the safety of the cat roller is improved, and the cat is protected from accidental injuries.

[0034] Furthermore, a groove 202 is symmetrically arranged below the fixed wheel 2 , and a connecting plate 4 is symmetrically arranged below the groove 202 .

[0035] The connection between the connecting plate 4 and the rotating wheel 401 is fixedly connected, the rotating wheel 401 is located in the groove 202, and the middle bending part of the rotating wheel 401 fits with the guide strip 301 on the outer surface of the rotating wheel 3, which reduces the shaking and swaying of the roller and improves the comfort and stability of the cat when walking on it. The stable cat roller can reduce the risk of accidental falls or unstable rolling, protect the safety of the cat and avoid injuries.

[0036] Furthermore, a threaded rod 402 is connected through the middle of the connecting plate 4. A block 403 is provided on the side of the threaded rod 402 close to the rotating wheel 3, and a slot 302 is provided in the middle of the outer surface of the rotating wheel 3, and the side wall of the slot 302 is symmetrically inclined. The slot 302 and the block 403 are of the same size, and when the threaded rod 402 is rotated toward the side close to the slot 302, the block 403 gradually approaches the slot 302 and squeezes the edge of the slot 302 until the block 403 is stuck on the inner wall of the slot 302, so as to prevent the pet from using the cat roller at night or when no one is watching, thereby reducing the risk of accidents and ensuring that the owner can have a quiet environment during rest time.

[0037] It is worth mentioning that the outer surface of the block 403 is an inclined cone. When the threaded rod 402 is rotated, the block 403 squeezes the groove 202, and the rotating wheel 3 can be quickly fixed without positioning. It can be fixed with one hand, which is easy and convenient to operate and reduces the complexity of operation for users.

[0038] It should be additionally explained that the above mechanisms and components can be arranged to be connected or snap-fitted for easy disassembly and installation, so as to facilitate storage or transportation.
