[0024] Please see Figure 1-6 This utility model provides the following technical solution: a pet cage that is easy to fold and install, including a connecting frame 1, a hinge 2 fixedly installed on the inner side of the connecting frame 1, a side cage frame 3 fixedly installed on one side of the hinge 2, a second hinge 4 fixedly installed on the outer side of the side cage frame 3, a front cage frame 5 fixedly connected to one side of the connecting frame 1, a rear cage frame 6 fixedly connected to one side of the connecting frame 1, a support shaft 7 movably installed inside the connecting frame 1, and a top cage frame 8 movably connected to the surface of the support shaft 7. A second support shaft 9 is installed, and a bottom cage frame 10 is movably connected to the surface of the second support shaft 9. Mesh 11 is fixedly connected to the inner sides of the side cage frame 3, front cage frame 5, rear cage frame 6 and top cage frame 8. A square rod 12 is fixedly connected to the inner side of the bottom cage frame 10. A second square rod 13 is fixedly connected to the lower surface of the square rod 12. A support plate 14 is fixedly connected to one side of the connecting frame 1. A fixed frame 20 is fixedly connected to the upper surface of the top cage frame 8. A sliding groove 21 is fixedly installed on the upper surface of the connecting frame 1. An insert plate 22 is slidably installed inside the sliding groove 21.

[0025] In this embodiment, the symmetrical side cage frames 3 can be folded inwards via hinge 4, forming an inverted V shape. This causes the front cage frame 5 and the rear cage frame 6 to move closer to the center, shortening their distance. The top cage frame 8 can be folded downwards via support shaft 7, and the bottom cage frame 10 can be folded upwards via support shaft 9. After folding, the top cage frame 8 and the bottom cage frame 10 are located between the front cage frame 5 and the rear cage frame 6. During installation, the front cage frame 5 and the rear cage frame 6 can be pulled apart first, causing the side cage frames 3 to form a plane. Then, the top cage frame 8 can be pulled upwards, and the bottom cage frame 10 can be pushed downwards so that its edge reaches the support plate 14 to form a support. The support plate 14 supports the bottom cage frame 10 to form a cage bottom platform. The sliding insert plate 22 can be inserted into the fixing frame 20 on the upper surface of the top cage frame 8 to support the top cage frame 8. This pet cage will not cause parts to fall off after folding. The folding method is only achieved by manual pushing and pulling, making the folding and restoration operations simple and quick.

[0026] Specifically, square bars 12 and 13 are arranged in a horizontal array. The array of square bars 12 forms a platform at the bottom of the cage. Compared with traditional round bars, square bars make it easier for pets to stand and walk. Furthermore, square bars 12 and 13 are arranged in a crisscross pattern, which helps to improve the load-bearing capacity of the pet cage. Compared with the round bars of traditional pet cages, bars 12 and 13 can provide better support. They are suitable for most pets. Square bars generally have better bending resistance than round bars, and are less prone to deformation under load, making them suitable for long-term use.

[0027] Specifically, each pair of side cage frames 3 forms a group, and hinge 2 4 is located between the two side cage frames 3. The two symmetrical side cage frames 3 can be folded inward through hinge 2 4, which helps to reduce the space occupied by the pet cage after folding.

[0028] Specifically, both the bottom of the front cage frame 5 and the rear cage frame 6 are equipped with casters 15. With the casters 15, the pet cage can be moved when folded or in use, making it easier to move the pet cage manually.

[0029] Specifically, square holes 16 are provided on the sides of both the front cage frame 5 and the rear cage frame 6. A support rod 17 is inserted into the square hole 16. The support rod 17 is two-sectioned, and a connecting shaft 18 is movably installed inside the support rod 17. The two-section support rod 17 can be folded through the connecting shaft 18. When the support rod 17 is opened to form a straight rod, both ends can be inserted into the square hole 16 to support the receiving plate 19, which is conducive to the horizontal placement of the receiving plate 19.

[0030] Specifically, a receiving tray 19 is provided above the support rod 17. The receiving tray 19 is placed on the support rod 17 and can collect pet feces and food scraps to keep the cage bottom platform clean.

[0031] Specifically, the front cage frame 5 also includes a U-shaped frame 51, with a cage door 52 movably connected inside the U-shaped frame 51. A limit rod 53 is fixedly connected to one side of the cage door 52, and a fixed shaft 54 ​​is fixedly connected to one side of the U-shaped frame 51. A locking plate 55 is rotatably mounted on the surface of the fixed shaft 54. The locking plate 55 can rotate through the fixed shaft 54, so that when the locking plate 55 is engaged in the limit rod 53, it can block the cage door 52 and prevent the pet from escaping.

[0032] The working principle or usage process of this utility model is as follows: During installation, the front cage frame 5 and the rear cage frame 6 can be pulled apart first, thereby causing the side cage frame 3 to form a plane. Then, the top cage frame 8 can be pulled upwards, and the bottom cage frame 10 can be pushed downwards so that its edge reaches the support plate 14 to form a support. The support plate 14 supports the bottom cage frame 10 to form a cage bottom platform. The sliding insert plate 22 can be inserted into the fixing frame 20 on the upper surface of the top cage frame 8 to support the top cage frame 8. Then, the support rod 17 can be opened to form a straight rod, and its two ends can be inserted into the square holes 16 to support the receiving plate 19. Then, the receiving plate 19 can be placed on the support rod 17. The receiving plate 19 can collect pet feces and food scraps. To ensure the cleanliness of the cage bottom platform, when folding, first remove the receiving plate 19, then remove the support rod 17, then slide the insert plate 22 away from the fixed frame 20, open the top cage frame 8 so that the bottom cage frame 10 can be folded upward through the second support shaft 9, then push the top cage frame 8 downward through the first support shaft 7, and then the symmetrical side cage frames 3 can be folded inward through the second hinge 4. After folding, it forms an inverted V shape, which drives the front cage frame 5 and the rear cage frame 6 to move closer to the center, shortening the distance between them. After folding, the top cage frame 8 and the bottom cage frame 10 are located between the front cage frame 5 and the rear cage frame 6. This pet cage will not cause parts to fall off after folding. The folding method is only through manual pushing and pulling, so the folding and restoration operations are simple and quick.
