Abstract

The present invention discloses a novel pet cage door, including a door frame and a switch door capable of rotating relative to the door frame so as to be opened and closed. A locking apparatus is disposed between the switch door and the door frame, and the locking apparatus includes a housing disposed on the switch door. The present invention has a simple structure and requires low costs.

Claims

1. A pet cage door, comprising a door frame (1) and a switch door (2) capable of rotating relative to the door frame (1) so as to be opened and closed, wherein a locking apparatus (3) is disposed between the switch door (2) and the door frame (1), the locking apparatus (3) comprises a housing (31) disposed on the switch door (2), and the housing (31) is internally provided with a vertical lock bar (32) capable of vertically moving so as to be inserted into a vertical socket on the door frame (1);

the vertical lock bar (32) is provided with a raised portion (33) raised from a side wall of the vertical lock bar (32);

the housing (31) is further internally provided with a lock bar retaining member (34) capable of rotating relative to the housing (31), and the lock bar retaining member (34) comprises a rotation portion (341) and a retaining portion (342) raised on the rotation portion (341);

before the rotation portion (341) rotates, the retaining portion (342) abuts against the raised portion (33) to prevent the vertical lock bar (32) from vertically moving; and

after the rotation portion (341) rotates, the retaining portion (342) is separated from the raised portion (33) to reserve a space for vertical movement of the vertical lock bar (32).

2. The pet cage door according to claim 1, wherein the vertical lock bar (32) comprises a first vertical bar segment (321) matching the vertical socket on the door frame (1), a lower portion of the first vertical bar segment (321) is transversely bent to form a cross bar segment (322), the cross bar segment (322) is vertically bent to form a second vertical bar segment (323), and the housing (31) is further internally provided with a reset spring (35) sleeved on the second vertical bar segment (323) and used for resetting the vertical lock bar (32).

3. The pet cage door according to claim 2, wherein the raised portion (33) is further provided with a toggle handle (36) integrated with the raised portion (33) and exposed from the housing (31), and the housing (31) is provided with a sliding slot (37) for the toggle handle (36) to vertically slide.

4. The pet cage door according to claim 3, wherein there are two vertical lock bars (32), and the two vertical lock bars (32) respectively match vertical sockets on an upper board and a lower board of the door frame (1);

there are two raised portions (33), and the two raised portions (33) are respectively disposed on the corresponding vertical lock bars (32); and

two retaining portions (342) are arranged on the rotation portion (341) along a circumference, and when the rotation portion (341) rotates, the two retaining portions (342) both abut against or are separated from the raised portions (33).

5. The pet cage door according to claim 4, wherein an arc-shaped protrusion (343) whose surface is arc-shaped is disposed on the rotation portion (341), and a plurality of clamping slots (38) capable of matching the arc-shaped protrusion (343) so as to position the rotation portion (341) is disposed on an inner side wall of the housing (31).

6. The pet cage door according to claim 4, wherein a knob (39) exposed from the housing (31) is connected to the rotation portion (341).
