The extension block 210 pushes the fixed seat 27 connected to it in front to shift to the right. The fixed seat 27 connected to the extension block 210 pushes the connecting rod 29 to rotate through the connecting rod 3 28 on its right side. While the connecting rod 4 29 is rotating, it drives the other fixed seat 27 to move to the left through the other connecting rod 3 28, realizing the relative movement of the two fixed seats 27. The two fixed seats 27 also pull the connecting rod 1 25 backward through the connecting rod 2 26. While the connecting rod 1 25 is backward, it pulls the locking tongue 23 away from the U-shaped card seat 216.

[0026] like Figure 4 As shown, this utility model provides a technical solution: a sliding groove is provided on the left side of the base 21 and is slidably connected to the slider 213 and the adjusting seat 212. A locking block 214 is fixedly connected to the base 21 below the adjusting seat 212. A lever 215 is rotatably connected inside the adjusting seat 212. When the adjusting seat 212 is pulled forward, the lever 215 is rotated to lock it into the locking block 214 to prevent the locking tongue 23 from springing back.

[0027] like Figure 5 As shown, this utility model provides a technical solution: four limiting blocks 24 and locking tongues 23 are all fixedly connected with springs 217, and the front ends of the four locking tongues 23 are all engaged with U-shaped brackets 216. The four U-shaped brackets 216 are all fixedly connected to the bottom of the box body 11. The upper end of the locking tongue 23 is provided with a ramp, so that when the four U-shaped brackets 216 descend, they push the locking tongue 23 backward through the ramp above the locking tongue 23. At this time, the springs 217 contract. When the middle slot of the U-shaped bracket 216 is aligned with the locking tongue 23, the springs 217 rebound and push the locking tongue 23 into the U-shaped bracket 216, at which point the box body 11 cannot be moved.

[0028] like Figure 6 As shown, this utility model provides a technical solution: a fixed rod 61 is rotatably connected to the rear of the base 21; a handle nut 62 is threadedly connected to the outer wall of the fixed rod 61; an extension section 64 is movably connected inside the fixed rod 61; a handle nut 63 is threadedly connected to the outer wall of the extension section 64; an extension section 66 is slidably connected inside the extension section 64; handles 67 are fixedly connected to the left and right sides of the extension section 66; and a support block is fixedly connected to the box 11 below each of the two handles 67. 65. When the lever 6 is needed, hold the handle 67 and pull the extension section 2 66 away from the extension section 1 64. Then fix the relative position of the extension section 1 64 with the handle nut 2 63. Then pull the extension section 1 64 away from the fixing rod 61. Then fix the extension section 1 64 with the handle nut 1 62. At this time, the pet carrier 1 can be pulled by the handle 67. When the lever 6 is not needed, loosen the handle nut 2 63 and the handle nut 1 62 and put the handle 67 into the support block 65.

[0029] The working principle of this detachable and assembleable pet carrier will be explained in detail below.

[0030] like Figure 1-6 As shown,

[0031] When it is time to put the pet in, pinch the first lock cylinder 14 and the second lock cylinder 18 inwards to move them away from the positioning holes of the box body 11. At this time, the grille 13 can be opened. After that, pinch the first lock cylinder 14 and the second lock cylinder 18 inwards again and rotate the grille 13 to reset it. Release the first lock cylinder 14 and the second lock cylinder 18 to allow them to be inserted back into the positioning holes of the box body 11. When it is time to remove the pet box 1 from the bottom plate 2, move the adjusting seat 212 forward. At this time, the adjusting seat 212 pushes the extension block 210 to the right through the slider 213 and the connecting rod 211. At the same time, the extension block 210 will also push its front end forward. The fixed seat 27 of the connecting rod shifts to the right. The fixed seat 27 connected to the extension block 210 pushes the connecting rod 4 29 to rotate via the connecting rod 3 28 on its right side. While the connecting rod 4 29 rotates, it drives the other fixed seat 27 to move to the left via another connecting rod 3 28, realizing the relative movement of the two fixed seats 27. At the same time, the two fixed seats 27 pull the connecting rod 1 25 backward via the connecting rod 2 26. While the connecting rod 1 25 is backward, it pulls the locking tongue 23 away from the U-shaped latch 216. While the locking tongue 23 is backward, it presses the spring 217. At this time, the lever 215 is rotated to lock it into the locking block 214, preventing the spring 217 from being locked. 217 rebounds, at which point the pet carrier 1 can be removed. When the pet carrier 1 needs to be placed back into the base plate 2, first disengage the lever 215 from the locking block 214, then slide the adjusting seat 212 backward, and then insert the lever 215 into the locking block 214. At this time, spring 217 rebounds, pushing the locking tongue 23 to reset. The pet carrier 1 can then be inserted into the base plate 2. Because the upper end of the locking tongue 23 has a ramp, when the four U-shaped brackets 216 descend, they push the locking tongue 23 backward through the ramp above the locking tongue 23. At this time, spring 217 contracts. When the middle slot of the U-shaped bracket 216 aligns with the locking tongue 23, the spring... Spring 217 rebounds, pushing the locking tongue 23 into the U-shaped bracket 216, at which point the box body 11 cannot be moved. When the pull rod 6 is needed, hold the handle 67 and pull the extension section 2 66 away from the extension section 1 64. Then, fix the relative position of the extension section 1 64 with the handle nut 2 63. Then pull the extension section 1 64 away from the fixing rod 61. Then, fix the extension section 1 64 with the handle nut 1 62. At this time, the pet box 1 can be pulled by the handle 67. When the pull rod 6 is not needed, loosen the handle nut 2 63 and the handle nut 1 62 and put the handle 67 into the support block 65.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
