Description

Technical Field

[0001] The utility model relates to the technical field of pet appliances, in particular to a cage grid connection structure of a pet cage and the field of pet cages. Background Art

[0002] Currently, pet cages on the market are usually connected by bent metal rings, so that the cages can be rotated and folded relative to each other. The folding method is usually to first flip the two side cages inward to above the lower cage, and then fold the front cage, upper cage and rear cage in a zigzag shape above the side cages. This type of metal ring connection method actually requires two rods to move inside the metal ring to achieve the rotation of the cage. Therefore, the metal ring usually needs to leave a large margin for the rods to move. This makes it easy for the cage bars to move after the pet cage is unfolded, making the pet cage structure relatively loose. When the pet moves inside the pet cage, it is easy for the cage bars to scratch against the metal ring, resulting in noise. In addition, the folding of this type of pet cage is actually achieved by the deformation of the cage bars during folding. If no restraint structure is installed after folding, the cage bars will tilt up on their own. After long-term storage and transportation of this type of pet cage, the deformation of the cage bars is often difficult to recover, thereby affecting the unfolding of the pet cage and further affecting the stability of the pet cage.

[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] Reference Figures 1 to 4A preferred embodiment of the cage-grid connection structure of the present invention includes a connector 10 and two rods 21 located on two cage grids 20, respectively. The connector 10 is provided with two connecting holes 11 spaced apart from each other. The two rods 21 are respectively inserted into the two connecting holes 11, and at least one connecting hole 11 allows the rod 21 inserted therein to rotate within the connecting hole 11. In this cage-grid connection structure, the rods 21 of the cage grids 20 can rotate within at least one connecting hole 11, thereby allowing the corresponding cage grid 20 to rotate for folding. The spacing between the two connecting holes 11 is constant. By appropriately setting the dimensional relationship between the cage grids 20, deformation of the cage grids 20 during folding can be reduced, and the stability of the pet cage can be improved when the pet cage is unfolded. There is no friction or mutual movement between the rods 21, which can reduce noise during use.

[0028] As a preferred embodiment of the cage-grid connection structure in the present invention, it may also have the following additional technical features:

[0029] In this embodiment, the connector 10 includes a base 12 and a blocking member 13. The base 12 includes two recessed portions 14 with openings facing each other. A mounting opening 15 is left between the two recessed portions 14 for the rod 21 to pass through. The blocking member 13 is mounted on the base 12 and is used to close the mounting opening 15 and the openings of the two recessed portions 14. The two connecting holes 11 are formed by the two recessed portions 14 being blocked by the blocking member 13. During assembly, the rod 21 can first be inserted through the mounting opening 15 and installed in the recessed portions 14, and then the blocking member 13 can be installed on the base 12. The inherent structures of the base 12 and the blocking member 13 are used to withstand external forces during use. The structure is simple and reliable, and is easy to install and use. In other embodiments, the connector 10 can also adopt other suitable assembly structures, and is not limited to this.

[0030] In this embodiment, the blocking member 13 has an I-shaped cross-section. The sliding grooves 16 on either side of the blocking member 13 respectively mate with the side panels of the two recessed portions 14. The blocking member 13 is slidably inserted into the base 12 through the engagement of the sliding grooves 16 with the side panels of the two recessed portions 14. A locking structure is provided between the base 12 and the blocking member 13 to restrict the blocking member 13 from sliding relative to the base 12. During assembly in this manner, after the rod 21 enters the recessed portion 14, the blocking member 13 can be directly slid into the base 12 through the mounting opening 15. This provides a pre-fixed position and facilitates subsequent locking of the blocking member 13. The structure is simple and easy to install.

[0031] In this embodiment, a fin 22 is provided on a rod 21. The fin 22 is clamped by the base 12 and the blocking member 13 to limit the rotation of the rod 21 in which it is located relative to the connecting member 10. This structure can be used in locations where it is necessary to limit the relative rotation of the connecting member 10 and the rod 21. It can reduce the torsional force applied between the connecting hole 11 and the rod 21, making it more secure and reliable. It also reduces the requirements for the size of the rod 21 and the structural strength of the connecting member 10, helping to reduce costs. In other embodiments, the fin 22 can also be optionally provided on the outside of the connecting member 10 and abut against the outer wall of the connecting member 10 to limit the relative rotation of the connecting member 10 and the rod 21. Alternatively, the relative rotation of the connecting member 10 and the rod 21 can be limited solely by the shape matching relationship between the rod 21 and the connecting hole 11. The present invention is not limited to this.

[0032] In this embodiment, the locking structure is a screw 17. The fin 22 is provided with a positioning hole 23 corresponding to the screw 17. The screw 17 is inserted into the positioning hole 23. This simple structure is easy to manufacture and assemble, and the connection is secure and not easily loosened. It also restricts the sliding of the connector 10 along the rod 21, making it more secure and reliable. In other embodiments, the locking structure may also adopt other commonly used structures such as a buckle or a latch, and is not limited to these. In this embodiment, a gasket 18 is provided on the blocking member 13. The gasket 18 cooperates with the screw 17 to achieve locking, facilitating the manufacture of the base 12 and blocking member 13.

[0033] In actual application, by setting the shape of the connecting hole 11 and the corresponding rod 21, the rotation of the rod 21 in the connecting hole 11 can be adjusted. For example, the rod 21 and the connecting hole 11 are both set to be circular, or the connecting hole 11 is set to other shapes but the rod 21 is circular, or the connecting hole 11 is larger than the size of the rod 21, etc., so that the rod 21 can rotate in the connecting hole 11; and if the connecting hole 11 and the rod 21 are both set to compatible non-circular shapes such as square, oblate, triangle, etc., the rotation of the rod 21 in the connecting hole 11 can be restricted. For example, in this embodiment, one of the two connecting holes 11 on the connecting member 10 is a square hole, and the rod 21 inserted in the connecting hole 11 is a square rod adapted thereto, thereby restricting the rotation of the connecting member 10 relative to the rod 21; Figure 5 , is another preferred embodiment of the connecting member 10. In this embodiment, both connecting holes 11 are square holes, and the rod 21 can be a round rod to enable it to rotate in the connecting hole 11, or the rod 21 can also be a square rod to limit the rotation of the rod 21 relative to the connecting member 10, and the two rods 21 can be a combination of a round rod and a square rod so that only one rod 21 can rotate in the connecting hole 11, etc.; these are all commonly used technical means in this field, and those skilled in the art can flexibly select and adjust them as needed.

[0034] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0035] Reference Figure 6 The present invention also provides a pet cage, comprising a main cage body 30, on which the cage grid connection structure of the present invention is applied. Since the cage grid connection structure of the present invention is adopted, the cage also has the above advantages.

[0036] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
