DETAILED DESCRIPTION

(4) The present utility model is further described below with reference to the accompanying drawings.

Embodiment 1

(5) As shown in FIG. 1, a door of a pet cage includes a door frame 1 disposed on a cage body, where the door frame 1 is provided with multiple insertion buckles 2 protruding toward one side of the door frame 1, the door frame 1 is further provided with a door stop 3 capable of rotating relative to the door frame 1 to close same, the door stop 3 is provided with a door bolt 4 capable of transversely sliding relative to same, one end of the door bolt 4 can be in insertion fit with one of the insertion buckles 2, the other end of the door bolt 4 is connected to a vertical bar 5 capable of transversely moving relative to the door stop 3 along with the door bolt 4, the end portion of the vertical bar 5 is provided with a transverse bar 6 that extends toward one side of the vertical bar 5, the end portion of the transverse bar 6 is provided with a turning-back bar 7 that extends toward one side of the vertical bar 5 and keeps spaced from the transverse bar 6, and the turning-back bar 7 can be in insertion fit with the other insertion buckle 2 on the door frame 1. The door bolt 4 on the door stop 3 can fit with the insertion buckle 2 on the door frame 1, and the turning-back bar 7 spaced from the door bolt 4 also can be in insertion fit with the insertion buckle 2 on the door frame 1, so when the door bolt 4 fits with the insertion buckle 2, the turning-back bar 7 is in inserted connection with the insertion buckle 2 at another place of the door frame 1. Therefore, when the door of the pet cage is locked, multiple locking points are provided, so as to ensure locking firmness of the door of the pet cage and to guarantee that a pet cannot escape.

(6) As shown in FIG. 1, the door bolt 4 is rotationally connected to the door stop 3, and the door bolt 4 includes a latch 41 and a handle 42, which can rotate relative to the door stop 3, where the handle 42 is connected to the latch 41, the latch 41 is in insertion fit with the insertion buckle 2, the door stop 3 is provided with an engaging position 8 capable of engaging with or disengaging from the handle 42 after the door bolt 4 rotates relative to the door stop 3, the latch 41 is further provided with an annular slot 43, and the vertical bar 5 is provided with a reducing sleeve 9 that is sleeved in the annular slot 43 and rotationally connected to the latch 41. The latch 41 is rotationally connected to the vertical bar 5 through the reducing sleeve 9 on the vertical bar 5, so the latch 41 can rotate relative to the vertical bar 5, and after the handle 42 is pulled to rotate, the handle 42 can engage with or disengage from the engaging position 8 on the door stop 3. Therefore, when the latch 41 is inserted into the insertion buckle 2, the handle 42 engages with the engaging position 8 to make the handle 42 blocked, so the latch 41 cannot slide transversely. Accordingly, the latch 41 keeps in inserted connection with the insertion buckle 2, and the turning-back bar 7 also keeps in inserted connection with the insertion buckle 2. When it is necessary to open the door of the cage, the handle 42 is rotated to make the handle 42 disengage from the engaging position 8. In this case, the handle 42 is no longer blocked, the latch 41 can slide transversely to disengage from the insertion buckle 2, and when sliding transversely, the latch 41 also pushes the vertical bar 5 transversely, so that the turning-back bar 7 disengages from the insertion buckle 2. Accordingly, the door of the cage is unlocked. Because it is necessary to rotate the handle 42 in order to make the latch 41 slide transversely, the stability of insertion fit between the latch 41 and the insertion buckle 2 is ensured, accidental disengagement of the latch 41 is prevented, and the locking firmness of the door of the cage is ensured.

(7) As shown in FIG. 1, the door stop 3 includes multiple vertical rods 31 that are spaced from one other, the engaging position 8 is formed in a space between the adjacent vertical rods 31, the handle 42 is U-shaped, and after the handle 42 rotates relative to the door stop 3, the end portion of the handle 42 is inserted into the space between the adjacent vertical rods 31 or withdraws from the space between the adjacent vertical rods 31. During inserted connection between the latch 41 and the insertion buckle 2, the end portion of the handle 42 is inserted into a space between the adjacent vertical rods 31. If the latch 41 is driven to move transversely, the vertical rods 31 will block the handle 42, so as to ensure that the latch 41 keeps in an inserted connection state with the insertion buckle 2. When it is necessary to open the door of the cage, the handle 42 is rotated, and the end portion of the handle 42 withdraws from the space between the adjacent vertical rods 31 in a rotating process. In this case, the latch 41 can be pushed transversely to make the latch 41 disengage from the insertion buckle 2.

(8) As shown in FIG. 1 and FIG. 2, the vertical bar 5, the transverse bar 6 and the turning-back bar 7 are of an overall structure formed by integrated bending.

(9) As shown in FIG. 2, the door stop 3 is provided with a sleeve buckle 11 that allows the transverse bar 6 to slide therein.

Embodiment 2

(10) As shown in FIG. 3, the difference between Embodiment 2 and Embodiment 1 is as follows.

(11) The middle of the vertical bar 50 (similar to vertical bar 5 of Embodiment 1 discussed above) is rotationally connected to the latch 41 through the reducing sleeve 9, the upper end and the lower end of the vertical bar 50 are provided with the transverse bar 6 separately, the middle of the transverse bar 6 is connected to the vertical bar 50, one end of the transverse bar 6 is connected to the turning-back bar 7, the other end of the transverse bar 6 is provided with an insertion segment 61 capable of being in inserted connection with the insertion buckle 2 on the door frame 1, and the outer side of the vertical bar 50 is further provided with a reinforcing bar 10 connected to the transverse bar 6. Therefore, the upper and lower portions of the door stop 3 both fit with the insertion buckles 2 on the door frame 1 through the turning-back bar 7 and the insertion segment 61 respectively, and the middle of the door stop 3 fits with the insertion buckle 2 on the door frame 1 through the latch 41. Therefore, the present embodiment has five locking points, thus ensuring locking firmness of the door of the pet cage.
