In the initial state, the top cage frame 101, the bottom cage frame 102, the rear cage frame 103, the front cage frame 104 and the two side cage frames 105 conflict with each other and form a square frame structure. The inner cavity of the square frame structure is used to accommodate pets, and the top cage frame 101 is located at Directly above the bottom cage frame 102, the top cage frame 101 and the bottom cage frame 102 are arranged horizontally, the rear cage frame 103 is fixedly connected to the top cage frame 101 and the bottom cage frame 102, the rear cage frame 103 is arranged vertically, the bottom of the front cage frame 104 is hingedly connected to the bottom cage frame 102 by a hinge, the top of the front cage frame 104 is detachably fixedly connected to the top cage frame 101 by a first connecting assembly 2, each side cage frame 105 is connected to the bottom cage frame 102 by a rotating assembly 3, and each side cage frame 105 is detachably fixedly connected to the top cage frame 101 by a second connecting assembly 4.

[0035] like Figure 1 and Figure 2 and Figure 3, through the first connecting component 2 and the second connecting component 4, the top cage frame 101, the bottom cage frame 102, the rear cage frame 103, the front cage frame 104 and the two side cage frames 105 are fixedly connected, and the pet cannot run out from the gaps between the top cage frame 101, the bottom cage frame 102, the rear cage frame 103, the front cage frame 104 and the two side cage frames 105. When the pet needs to be taken out or put in, the front cage frame 104 is disconnected from the top cage frame 101 through the first connecting component 2, and the pet can enter the inner cavity of the box body 1 or move out of the box body 1 from the front part of the square frame structure. When the pet grows in size or more pets need to be placed, the side cage frames 105 are disconnected from the top cage frame 101 through the second connecting component 4, and the inner cavity space of the box body 1 is increased by the rotating component 3, which is suitable for pets with larger sizes or more numbers, thereby improving the utilization rate of the device.

[0036] like Figure 6 and Figure 7 The rotating assembly 3 includes a connecting pipe 301 close to the side of the bottom cage 102 and fixed to the bottom cage 102. The side cage 105 is sleeved outside the connecting pipe 301 and rotatably connected to the connecting pipe 301. Both sides of the side cage 105 are provided with intermediate support rods 302 rotatably connected to the connecting pipe 301. Each intermediate support rod 302 is provided with a side support rod 303 fixedly connected to the connecting pipe 301 on the side away from the side cage 105. The top of the side support rod 303 is fixed to the top cage 101.

[0037] like Figure 2 and Figure 3 and Figure 6 and Figure 7 The tops of the two side support rods 303, the tops of the two middle support rods 302 and the top of the side cage 105 are all fixedly connected through the top support mesh bag 5, the side support rod 303 and the adjacent middle support rod 302 are fixedly connected through the upper side support mesh bag 6, and the middle support rod 302 and the side of the side cage 105 are fixedly connected through the lower side support mesh bag 7.

[0038] like Figure 2 and Figure 3 and Figure 6 and Figure 7 When the side cage frames 105 are in a vertical state and conflict with the top cage frame 101, the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7 are all folded, which does not affect the use of the device. When the side cage frames 105 do not conflict with the top cage frame 101 and are in a horizontal state, the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7 are all unfolded, closing the gaps between the top cage frame 101, the side cage frames 105, the middle bracket, and the side brackets, reducing the possibility of pets escaping from the gaps between the top cage frame 101, the side cage frames 105, the middle bracket, and the side brackets.

[0039] like Figure 2 and Figure 3 The outer walls of the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7 are all integrated with PVC cat scratching cloth. By arranging PVC cat scratching cloth on the outer walls of the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7, the possibility of pets damaging the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7 in the inner cavity of the box 1 is reduced, thereby improving the service life of the device.

[0040] like Figure 2 and Figure 3 and Figure 4 and Figure 5 The first connecting component 2 includes a support 201, a V-shaped groove 202 is provided at the end of the support 201, and a groove 203 is provided in the inner cavity of the support 201 to communicate with the V-shaped groove 202. A block 205 with an arc-shaped cross-section is rotatably connected in the groove 203 through a short shaft 204. One end of the block 205 passes through the support 201 through the groove 203 and is movably connected to the support 201. The part of the block 205 passing through the support 201 is integrated with a handle 206. The outer wall of the block 205 is fixed to the inner wall of the groove 203 by a spring 207. A card rod 208 adapted to the V-shaped groove 202 and the block 205 is fixed on the front cage 104. The first connecting component 2 and the second connecting component 4 have the same structure.

[0041] like Figure 2 and Figure 3 and Figure 4 and Figure 5 The position of the card block 205 is limited by the spring 207, and the V-shaped groove 202 is closed by the card block 205 to limit the position of the card rod 208, so as to facilitate the fixed connection between the front cage frame 104 and the top cage frame 101, the side cage frame 105 and the top cage frame 101. The card block 205 is conveniently rotated manually by the handle 206 to improve the comfort of the staff. The card rod 208 is located on the side of the card block 205. When the card rod 208 moves, it will push the card block 205 to rotate, and will not press the card block 205 so that the card block 205 cannot move. The card rod 208 will not shake when it is located between the V-shaped groove 202 and the card block 205.

[0042] like Figure 2 and Figure 3 and Figure 4 and Figure 5 The support 201 and the top cage 101 are detachably fixedly connected through the installation component 8. The installation component 8 facilitates the disassembly and assembly of the support 201 and improves the stability of the connection between the support 201 and the top cage 101.

[0043] like Figure 2 and Figure 3 and Figure 4 and Figure 5The mounting assembly 8 includes a lower mounting plate 801 arranged at the lower end of the top cage 101 and in contact with the lower surface of the top cage 101. The upper end of the top cage 101 is provided with an upper mounting plate 802 in contact with the upper surface of the top cage 101. The support 201 is fixed to the side of the upper mounting plate 802 away from the top cage 101. The upper mounting plate 802 and the lower mounting plate 801 are fixedly connected by a number of evenly arranged bolts 803. The upper mounting plate 802 and the lower mounting plate 801 are respectively placed on the upper and lower sides of the top cage 101 and fixedly connected by bolts 803, which facilitates the disassembly and assembly of the upper mounting plate 802 and the lower mounting plate 801 and facilitates the adjustment of the position of the support 201.

[0044] like Figure 1 and Figure 2 and Figure 3 A handle 9 for conveniently grabbing the device is fixed at the middle position on the upper surface of the top cage 101. By providing the handle 9, it is convenient to take the device.

[0045] When in use, when it is necessary to put the pet into the inner cavity of the box body 1 or move the pet out of the inner cavity of the box body 1, the staff member grabs the handle 206 and manually rotates the handle 206. The handle 206 rotates around the short axis 204. The rotation of the handle 206 drives the block 205 of the structure integrated with the handle 206 to rotate. The spring 207 is compressed, and the block 205 rotates into the groove 203 and no longer limits the card rod 208. The card rod 208 is manually pushed. The movement of the card rod 208 drives the front cage frame 104 of the structure integrated with the card rod 208 to rotate. The front cage frame 104 rotates to expose the front opening part of the box body 1. At this time, the pet can be put into the inner cavity of the box body 1 or moved out of the inner cavity of the box body 1. The handle 206 is released, and the spring 207 rebounds, driving the handle 206 and the block 205 to rotate in the opposite direction around the short axis 204. The end of the block 205 conflicts with the wall of the V-shaped groove 202.

[0046] After completing the above operation, the user pushes the front cage 104 in the opposite direction, causing the front cage 104 and the integrated structure of the card rod 208 to rotate in the opposite direction. The card rod 208 rotates and contacts the outer wall of the card block 205. The card rod 208 contacts the side of the card block 205. The card block 205 has an inclined arc surface facing the card rod 208. As the card rod 208 moves, the card block 205 rotates around the short axis 204 under the pressure of the card rod 208, and the spring 207 is compressed until the card rod 208 is stuck between the V-groove 202 and the card block 205. In the gap, the latch rod 208 does not exert pressure on the block 205, and the spring 207 rebounds, driving the block 205 to rotate in the opposite direction, thereby causing the end of the block 205 to interfere with the V-shaped groove 202, limiting the latch rod 208, and thus limiting the front cage 104. Even if the pet runs and jumps in the inner cavity of the box 1 and pushes the front cage 104, it will not cause the front cage 104 to open. If the latch rod 208 cannot push the block 205, the user manually pushes the handle 206 to help the front cage 104 be fixedly connected to the top cage 101;

[0047] When the number of pets to be placed in the inner cavity of the box body 1 increases, the size of the pets increases, or more living space is needed, the handle 206 connecting the side cage frame 105 and the top cage frame 101 is manually pushed, and then the clamping rod 208 on the side cage frame 105 is pushed. The clamping rod 208 on the side cage frame 105 is disconnected from the adjacent clamping block 205, and the side cage frame 105 is manually pushed. The side cage frame 105 rotates to a horizontal state and contacts the ground or table. The side cage frame 105 drives the top support mesh bag 5 fixed to the side cage frame 105 to unfold. The unfolded top support mesh bag 5 drives the middle support rod 302 fixed to the top support mesh bag 5 to rotate. The rotation of the middle support rod 302 drives the upper side connecting the side support rod 303 and the middle support rod 302. The side support mesh bag 6 and the lower side support mesh bag 7 connecting the middle support rod 302 and the side cage frame 105 are unfolded, and the top support mesh bag 5, the upper side support mesh bag 6, and the lower side support mesh bag 7 close the gaps between the side cage frames 105 and the top cage frame 101, the front cage frame 104 and the rear cage frame 103, thereby increasing the inner space of the box body 1. At the same time, the pet cannot escape from the gaps between the side cage frames 105 and the top cage frame 101, the front cage frame 104 and the rear cage frame 103. In order to improve the stability of the device, a counterweight block is detachably fixed on the side cage frame 105. This is the usage process of this pet breeding box with a high application rate. At the same time, the contents not described in detail in this manual belong to the existing technology well known to professional and technical personnel in this field.
