[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] like Figures 1-4 As shown, a pet door with a locking mechanism includes: a door frame 100, a door body 200, a first locking mechanism 300, and a second locking mechanism 400.

[0036] The door frame 100 includes an inner door 110 and an outer door 120, and the door frame 100 is provided with a locking hole 130.

[0037] The door body 200 includes a rotating side 210 and a limiting side 220. The door body 200 is rotatably connected to the door frame 100 through the rotating side 210. The door body 200 is located between the door interior 110 and the door exterior 120. The door body 200 can rotate toward the door interior 110 or the door exterior 120. The locking hole 130 is disposed between the door interior 110 and the door body 200, and between the door exterior 120 and the door body 200.

[0038] The first locking mechanism 300 is disposed in the door frame 100 and located between the door interior 110 and the door body 200. The first locking mechanism 300 includes a locking seat 310 and a locking pin 320. The locking seat 310 is located inside the door frame 100 and can be raised and lowered relative to the door frame 100. The locking pin 320 is connected to the locking seat 310 and can extend or retract from the locking hole 130.

[0039] Specifically, when the locking pin 320 of the first locking mechanism 300 extends out of the locking hole 130, the locking pin 320 of the first locking mechanism 300 can contact the limiting side 220 to restrict the door body 200 from rotating toward the door interior 110; when the locking pin 320 of the first locking mechanism 300 retracts into the locking hole 130, the door body 200 can rotate freely toward the door interior 110.

[0040] The second locking mechanism 400 is disposed on the door frame 100 and located between the door exterior 120 and the door body 200. The structure of the second locking mechanism 400 is the same as that of the first locking mechanism 300.

[0041] Specifically, when the locking pin 320 of the second locking mechanism 400 extends out of the locking hole 130, the locking pin 320 of the second locking mechanism 400 can contact the limiting side 220, thereby restricting the door body 200 from rotating toward the outside of the door 120; when the locking pin 320 of the second locking mechanism 400 retracts into the locking hole 130, the door body 200 can rotate freely toward the outside of the door 120.

[0042] Specifically, the extension or retraction of the locking pin 320 into the locking hole 130 can be controlled manually or automatically, without being specifically limited here.

[0043] In this embodiment, the first locking mechanism 300 restricts the door 200 from rotating toward the inside 110 of the door, and the locking pin 320 is manually or automatically extended or retracted into the locking hole 130, thereby locking the pet door in the open / closed state and restricting outside pets from entering.

[0044] In this embodiment, the second locking mechanism 400 restricts the door 200 from rotating toward the outside 120, and the locking pin 320 is manually or automatically extended or retracted into the locking hole 130, thereby locking the pet door in the open / closed state and preventing pets from escaping from the house.

[0045] like Figures 1-4 As shown, based on the above embodiment, the first locking mechanism 300 further includes a return spring 330. One end of the return spring 330 contacts the door frame 100, and the other end of the return spring 330 contacts the locking seat 310. The return spring 330 pushes the locking seat 310 and drives the locking pin 320 to extend out of the locking hole 130.

[0046] In this embodiment, the return spring 330 pushes the locking seat 310 and drives the locking pin 320 to extend out of the locking hole 130. Therefore, under normal circumstances, the locking pin 320 can contact the limiting side 220 to restrict the door body 200 from rotating toward the inside 110 or the outside 120 of the door, thus playing a safety protection role and restricting outside pets from entering or pets from escaping from the house.

[0047] like Figures 1-4 As shown, based on the above embodiment, the locking seat 310 is provided with a pressure plate 311, and the first locking mechanism 300 also includes a rotating shaft 340 and an eccentric wheel 350. The rotating shaft 340 is fixed relative to the door frame 100 and can rotate around its own axis. The eccentric wheel 350 is connected to the rotating shaft 340, and the pressure plate 311 is located between the eccentric wheel 350 and the return spring 330.

[0048] Specifically, the rotation of the rotating shaft 340 around its own axis can be controlled manually or automatically, without being specifically limited here.

[0049] In this embodiment, the pressure plate 311 is located between the eccentric wheel 350 and the return spring 330. Therefore, when the return spring 330 pushes the locking seat 310, it will press against the eccentric wheel 350 and rotate with the rotating shaft 340 around its own axis, causing the eccentric wheel 350 to rotate. This will cause the locking seat 310 to reciprocate linearly through the pressure plate 311, so as to realize that the locking pin 320 extends or retracts into the locking hole 130.

[0050] like Figures 1-4 As shown, based on the above embodiment, the first locking mechanism 300 further includes a motor 360, which is connected to the door frame 100. The rotating shaft 340 is connected to the output shaft of the motor 360, and the motor 360 can drive the rotating shaft 340 to rotate.

[0051] In this embodiment, the rotating shaft 340 is fixedly connected to the output shaft of the motor 360, and the motor 360 can drive the rotating shaft 340 to rotate, thereby realizing automatic control of the rotating shaft 340 without the need for manual control by the user.

[0052] like Figures 1-4 As shown, based on the above embodiment, the door frame 100 is further provided with a guide post 140, and the locking seat 310 is provided with a guide hole 312. The guide post 140 is slidably connected to the guide hole 312, thereby allowing the locking seat 310 to be raised and lowered and connected to the door frame 100.

[0053] In this embodiment, the guide post 140 is slidably connected to the guide hole 312 so that the locking seat 310 can be raised and lowered to be connected to the door frame 100. This guides the raising and lowering of the locking seat 310 relative to the door frame 100, thereby limiting the movement direction of the locking pin 320 and keeping it always aligned with the locking hole 130.

[0054] like Figures 1-4 As shown, based on the above embodiment, the guide post 140 is provided with a limiting block 141, and the locking seat 310 is also provided with a limiting groove 313. The limiting groove 313 communicates with the guide hole 312, and the limiting block 141 is located in the limiting groove 313 and can move along the length direction of the limiting groove 313.

[0055] In this embodiment, the limiting block 141 is located in the limiting groove 313 and can move along the length direction of the limiting groove 313. It assists the locking seat 310 in raising and lowering relative to the door frame 100 and plays a guiding role. At the same time, the limiting block 141 can contact the limiting groove 313 to limit the range of motion of the locking seat 310.

[0056] As Figures 1-4 shown, on the basis of the above-mentioned embodiments, a remote control system is further included, which is in communication connection with the motor 360 of the second locking mechanism 400 and is used to control whether the motor 360 of the second locking mechanism 400 works or not.

[0057] In the present embodiment, the management of the opening and closing of the pet door towards the door exterior 120 can be realized by presetting the access time and the free time through the remote control system, and meanwhile, the motor 360 of the second locking mechanism 400 can be temporarily controlled through the remote control system so as to make the locking pin 320 extend or retract from the locking hole 130.

[0058] As Figures 1-4 shown, on the basis of the above-mentioned embodiments, a pet face recognition system 400 is further included, which is connected with the door frame 100 and located at the door exterior 120, and the pet face recognition system 400 is in electrical connection with the motor 360 and is used to recognize the pet face so as to control whether the motor 360 works or not.

[0059] In the present embodiment, the management of the opening and closing of the pet door towards the door interior 110 can be realized through the pet face recognition system 400.
