Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a pet door. Background Technology

[0002] As living standards continue to improve, more and more families are keeping pets (such as dogs and cats). Currently, many families install pet doors on their doors or walls. A pet door is a device that allows pets to freely enter and exit the house. Pets do not need to rely on their owners to open the door, which can reduce anxiety or barking caused by waiting, increase the pet's freedom and independence, and improve the convenience of life for owners who do not need to frequently open and close the door for their pets.

[0003] In existing technology, most pet doors only have opening and closing functions. When the pet door is open, pets can freely enter and exit from the outside to the inside or vice versa. When the pet door is closed, pets are completely prohibited from entering or exiting. In daily life, sometimes pets are outdoors and users want them to be able to enter the house but not go outside again; other times pets need to use the pet door to go from the house to the outside for play, and after play, they cannot directly return to the house but must be washed before being allowed to enter. Clearly, the above types of pet doors are too simplistic and cannot meet all user needs, nor can they provide precise management of pet activities. Utility Model Content

[0004] The purpose of this utility model is to provide a pet gate that can flexibly control the entry and exit of pets according to different usage needs, accurately manage pet activities, meet all the needs of users, and has strong security and flexibility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Provides a pet door, including:

[0007] A door frame assembly is configured to be mounted on a door, the door frame assembly having an access passage through the door for connecting the inside and outside of the door;

[0008] A door panel, one end of which is rotatably mounted on the door frame assembly, is used for bidirectional closing, unidirectional closing, or bidirectional opening of the access passage. The other end of the door panel is provided with a first stop and a second stop at intervals along the thickness direction of the door panel. The second stop is located on the side of the door panel facing the access passage. Along the thickness direction of the door panel, the projections of the first stop and the second stop partially overlap or do not overlap. The first stop and the second stop form an insertion cavity.

[0009] A limiting insert is rotatably mounted on the door frame assembly. The limiting insert has a first position, a second position, and a third position inserted into the insertion cavity, and a fourth position away from the insertion cavity. In the first position, along the thickness direction of the door panel, the projection of the limiting insert at least partially overlaps with the projections of the first stop and the second stop, and the door panel closes the access passage in both directions. In the second position, along the thickness direction of the door panel, the projection of the limiting insert at least partially overlaps with the projection of the first stop, and the door panel closes the access passage in one direction. In the third position, along the thickness direction of the door panel, the projection of the limiting insert at least partially overlaps with the projection of the second stop, and the door panel closes the access passage in one direction. In the fourth position, the door panel opens the access passage in both directions.

[0010] Optionally, the door frame assembly includes a first frame body disposed at one end of the access channel. The first frame body and the access channel form a receiving chamber. The side of the first frame body facing the limiting plug has an insertion opening communicating with the receiving chamber. The limiting plug is rotatably disposed in the receiving chamber. In the fourth position, the limiting plug is housed in the receiving chamber. In the first position, the second position, and the third position, the limiting plug rotates out of the receiving chamber through the insertion opening and is inserted into the insertion cavity. The first frame body is disposed on either side of the door, inside or outside, and is detachably connected to the door.

The first transmission component is disposed in the receiving cavity, the limiting plug is disposed on the first transmission component, the first frame is provided with an insertion hole, the screwing component is screwably inserted into the insertion hole and extends into the receiving cavity, the screwing component is connected to the first transmission component, and the screwing component drives the limiting plug to rotate through the first transmission component.

[0012] Optionally, the first transmission assembly includes a first driving wheel, a first driven wheel, and a second driven wheel. The first driving wheel is disposed on the screwing member, the first driving wheel meshes with the first driven wheel, and the first driven wheel meshes with the second driven wheel. The limiting plug is disposed on the second driven wheel.

[0013] Optionally, the pet door further includes a control module, a rotary drive mechanism, and a second transmission component. The control module is communicatively connected to the rotary drive mechanism. The limiting plug is disposed on the second transmission component. The housing of the rotary drive mechanism is disposed in the receiving cavity. The output end of the rotary drive mechanism is drively connected to the second transmission component. The rotary drive mechanism drives the limiting plug to rotate through the second transmission component.

[0014] Optionally, the second transmission assembly includes a second driving wheel and a third driven wheel. The output end of the rotary drive mechanism is connected to the second driving wheel, the second driving wheel meshes with the third driven wheel, and the limiting plug is disposed on the third driven wheel.

[0015] Optionally, the pet gate further includes an identification module, which is communicatively connected to the control module and configured to identify identification devices on the pet.

[0016] Optionally, the door frame assembly further includes a sealing cover, a second frame, and a connector. The sealing cover is fitted onto the access passage and can seal the receiving chamber. The second frame is disposed on the side of the door away from the first frame, so that the second frame and the first frame are sandwiched between the two sides of the door. The connector passes through the first frame, the sealing cover, and the door, and is threaded into the second frame.

[0017] Optionally, the pet door further includes a first magnet and a second magnet. The first magnet is provided on the side of the door frame assembly facing the door panel, and the second magnet is provided on the side of the door panel facing the door frame assembly. The first magnet and the second magnet attract each other so that the door panel is attracted to the door frame assembly.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a pet gate, including a door frame assembly, a door panel, and a limiting plug. By setting the door panel, a first stop, a second stop, and the limiting plug, the limiting plug can be flexibly rotated according to different user needs. This allows the limiting plug to selectively limit either the first or second stop, or simultaneously limit both stops, or not limit either stop. This enables one-way closure (from outside to inside), one-way closure (from inside to outside), two-way closure, or two-way opening of the access passage. This allows for flexible control of pet entry and exit according to different usage needs, precise management of pet activities, and meets all user requirements, offering strong security and flexibility.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] This embodiment provides a pet door, such as Figures 1 to 6 As shown, the system allows for flexible control of pets' entry and exit according to different usage needs, enabling precise management of pet activities and meeting all user requirements. It also offers strong security and flexibility.

[0038] like Figures 1 to 3As shown, the pet door includes a door frame assembly 1, a door panel 2, and a limiting plug 3. The door frame assembly 1 is configured to be installed on the door. The door frame assembly 1 has an access passage 111 that passes through the door, connecting the inside and outside of the door. One end of the door panel 2 is rotatably mounted on the door frame assembly 1, allowing for two-way closing, one-way closing, or two-way opening of the access passage 111. Figures 2 to 4 As shown, a first stop 21 and a second stop 22 are spaced apart along the thickness direction of the door panel 2 at the other end of the door panel 2. The second stop 22 is located on the side of the door panel 2 facing the access passage 111. Along the thickness direction of the door panel 2, the projections of the first stop 21 and the second stop 22 partially overlap or do not overlap, and the first stop 21 and the second stop 22 surround and form an insertion cavity 23. Thus, it can be seen that the first stop 21 and the second stop 22 are staggered along the width direction of the door panel 2.

[0039] The limiting plug 3 is rotatably mounted on the door frame assembly 1. The limiting plug 3 has a first position, a second position, a third position, and a fourth position away from the insertion cavity 23, all inserted into the insertion cavity 23. In the first position, along the thickness direction of the door panel 2, the projection of the limiting plug 3 at least partially overlaps with the projections of the first stop 21 and the second stop 22, thus closing the entrance / exit passage 111 in both directions. In the second position, along the thickness direction of the door panel 2, the projection of the limiting plug 3 at least partially overlaps only with the projection of the first stop 21, thus closing the entrance / exit passage 111 in one direction. In the third position, along the thickness direction of the door panel 2, the projection of the limiting plug 3 at least partially overlaps only with the projection of the second stop 22, thus closing the entrance / exit passage 111 in one direction. In the fourth position, the door panel 2 opens the entrance / exit passage 111 in both directions.

[0040] In this embodiment, the door panel 2 is installed on the side facing the outside. When pets are prohibited from freely entering and exiting, the limiting plug 3 is rotated so that it is inserted into the insertion cavity 23 and in the first position, so that the projection of the limiting plug 3 at least partially overlaps with the projection of the first stop 21 and the projection of the second stop 22. At this time, if the door panel 2 is rotated in a direction away from the entrance / exit passage 111, the limiting plug 3 will abut against the second stop 22. If the door panel 2 is rotated in a direction close to the entrance / exit passage 111, the limiting plug 3 will abut against the first stop 21, thereby limiting the door panel 2 in both directions, so that the door panel 2 cannot be rotated, and the entrance / exit passage 111 is closed in both directions. This prevents pets outside from pushing the door panel 2 to open the entrance / exit passage 111 to enter the room, and at the same time, prevents pets inside from pushing the door panel 2 to open the entrance / exit passage 111 to go outside.

[0041] When pets are allowed to move freely in and out (i.e., pets are allowed to move from indoors to outdoors and from outdoors to indoors), the limiting plug 3 is rotated away from the insertion cavity 23. The limiting plug 3 is in the fourth position, and there is no projection overlap between the limiting plug 3 and the first stop 21 and the second stop 22. At this time, the door panel 2 can rotate in a direction away from the entrance and exit channel 111 or in a direction close to the entrance and exit channel 111, so that pets on both sides of the door panel 2 can push the door panel 2 to rotate, thereby opening the entrance and exit channel 111 and realizing bidirectional opening of the entrance and exit channel 111, allowing pets to move freely in and out.

[0042] When a pet is outdoors and the user wants the pet to be able to enter the room and not be able to go out again, the limiting plug 3 can be rotated so that the limiting plug 3 is inserted into the insertion cavity 23 and is in the third position. At this time, the projection of the limiting plug 3 only partially overlaps with the projection of the second stop 22. Therefore, the door panel 2 can be rotated in the direction close to the entrance and exit passage 111. If the door panel 2 is rotated in the direction away from the entrance and exit passage 111, the limiting plug 3 will abut against the second stop 22, so that the pet outdoors can only enter the room from the outside and cannot go out again.

[0043] When a user wants their pet to be able to go from indoors to outdoors for activities, but not to be allowed to return indoors immediately after the activity, the limiting plug 3 can be rotated so that it is inserted into the insertion cavity 23 and in the second position. At this time, the projection of the limiting plug 3 only partially overlaps with the projection of the first stop 21. Therefore, the door panel 2 can be rotated away from the access passage 111. If the door panel 2 is rotated towards the access passage 111, the limiting plug 3 will abut against the first stop 21, thus allowing the pet indoors to go outdoors for activities, but not to return indoors.

[0044] By setting up door panel 2, first stop 21, second stop 22 and limiting plug 3, the limiting plug 3 can be flexibly rotated according to different user needs. The limiting plug 3 can selectively limit the first stop 21 or the second stop 22, or limit both the first stop 21 and the second stop 22 simultaneously, or not limit either the first stop 21 or the second stop 22. This achieves one-way closure, one-way closure, two-way closure or two-way opening of the access passage 111 from the outside to the inside, from the inside to the outside, and so on. This allows for flexible control of pet entry and exit according to different usage needs, precise management of pet activities, and meets all user needs, with strong safety and flexibility.

[0045] In this embodiment, the limiting plug 3 is a semi-circular baffle, and the first stop 21 and the second stop 22 are both fan-shaped baffles, with no overlap in their projections. In other embodiments, the limiting plug 3, the first stop 21, and the second stop 22 may also be of other shapes, and the first stop 21 and the second stop 22 may partially overlap; this is not limited here.

[0046] In some embodiments, the door panel 2 may also be installed on the side facing inward. When an outdoor pet is allowed to enter the room and cannot go out again, the limiting plug 3 is rotated to the second position; when an indoor pet is allowed to go outside and cannot enter the room, the limiting plug 3 is rotated to the third position.

[0047] Optionally, such as Figures 1 to 3 As shown, the door frame assembly 1 includes a first frame 11. The first frame 11 is disposed at one end of the access channel 111, and the first frame 11 and the access channel 111 enclose a receiving chamber 14. Figure 2 , Figure 3 and Figure 5 As shown, the first frame 11 has an insertion opening 112 on the side facing the limiting plug 3, which communicates with the receiving chamber 14. The limiting plug 3 is rotatably disposed within the receiving chamber 14. In the fourth position, the limiting plug 3 is retracted into the receiving chamber 14. In the first, second, and third positions, the limiting plug 3 rotates out of the receiving chamber 14 through the insertion opening 112 and is inserted into the insertion cavity 23. The first frame 11 is located on either side of the door, inside or outside, and is detachably connected to the door.

[0048] When indoor pets are prohibited from going out and outdoor pets are prohibited from entering the room, the access passage 111 needs to be closed in both directions. In this case, rotate the limiting plug 3 so that the limiting plug 3 moves out of the receiving chamber 14 from the insertion opening 112 and is gradually inserted into the insertion chamber 23 until the limiting plug 3 is rotated to the first position. Similarly, when only indoor pets are prohibited from going out or only outdoor pets are prohibited from entering the room, the access passage 111 needs to be closed in one direction. The limiting plug 3 can be rotated to the second or third position. When pets are allowed to enter and exit freely, rotate the limiting plug 3 so that the limiting plug 3 moves from the insertion opening 112 into the receiving chamber 14. At this time, the access passage 111 is opened in both directions. By setting the first frame 11, the entrance and exit channel 111 and the first frame 11 form a receiving chamber 14, which provides storage space for the limiting plug 3, making it easy to store the limiting plug 3 and avoid damage caused by its exposure. At the same time, the first frame 11 can be detachably set on either side of the door, inside or outside. The structure is simple and easy to disassemble and install the pet door.

[0049] Optionally, the door frame assembly 1 further includes a sealing cover 12, a second frame 13, and a connector. The sealing cover 12 is fitted onto the access passage 111 and can seal the receiving chamber 14. The second frame 13 is located on the side of the door opposite to the first frame 11, so that the second frame 13 and the first frame 11 are sandwiched between the two sides of the door. The connector passes through the first frame 11, the sealing cover 12, and the door, and is threaded into the second frame 13. The structure is simple and facilitates the disassembly and installation of the door frame assembly 1. Furthermore, the first frame 11 and the second frame 13 sandwiched between the two sides of the bedroom door can strengthen the connection between the door frame assembly 1 and the door, enhancing structural stability.

[0050] For example, the connector includes a screw. In other embodiments, bolts or the like may be used as connectors as needed, and this is not limited here.

[0051] Optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, the pet door also includes a first transmission assembly 4 and a screwing component 5. The first transmission assembly 4 is disposed within the receiving chamber 14, and the limiting plug 3 is disposed on the first transmission assembly 4. The first frame 11 is provided with an insertion hole 113, and the screwing component 5 is screwed into the insertion hole 113 and extends into the receiving chamber 14. The screwing component 5 is connected to the first transmission assembly 4, and the screwing component 5 drives the limiting plug 3 to rotate through the first transmission assembly 4. When it is necessary to rotate the limiting plug 3 to switch between the first position, the second position, the third position, and the fourth position, the user can hold the screwing component 5 and rotate it, thereby causing the screwing component 5 to drive the limiting plug 3 to rotate through the first transmission assembly 4. The structure is simple and the operation is convenient.

[0052] In this embodiment, as Figure 2 , Figure 3 and Figure 6 As shown, the first transmission assembly 4 includes a first driving wheel 41, a first driven wheel 42, and a second driven wheel 43. The first driving wheel 41 is mounted on the screwing member 5, meshing with the first driven wheel 42, and the first driven wheel 42 meshing with the second driven wheel 43. A limiting plug 3 is mounted on the second driven wheel 43. When the user grips the screwing member 5 and rotates it, the screwing member 5 drives the first driving wheel 41 to rotate, which in turn drives the first driven wheel 42 to rotate, and then drives the second driven wheel 43 to rotate. Since the limiting plug 3 is mounted on the second driven wheel 43, the limiting plug 3 rotates with the second driven wheel 43, thereby switching the position of the limiting plug 3. This allows control over the bidirectional closing, unidirectional closing, or bidirectional opening of the access channel 111, meeting various user needs and enabling precise management of pet activities.

[0053] In other embodiments, the first transmission assembly 4 may also include only a first driving wheel 41 and a first driven wheel 42. The first driving wheel 41 is disposed on the screwing member 5, and the limiting plug 3 is disposed on the first driven wheel 42. The first driving wheel 41 and the first driven wheel 42 mesh with each other. Alternatively, only the screwing member 5 may be provided, and the screwing member 5 may be directly connected to the limiting plug 3.

[0054] In some embodiments, the pet door further includes a control module, a rotary drive mechanism, and a second transmission assembly. The control module is communicatively connected to the rotary drive mechanism, and the limit plug 3 is disposed on the second transmission assembly. The housing of the rotary drive mechanism is disposed within the receiving chamber 14, and the output end of the rotary drive mechanism is drively connected to the second transmission assembly. The rotary drive mechanism drives the limit plug 3 to rotate via the second transmission assembly. When it is necessary to rotate and change the position of the limit plug 3, the control module controls the rotary drive mechanism to start, and then the output end of the rotary drive mechanism drives the limit plug 3 to rotate via the second transmission assembly. When the limit plug 3 rotates to the desired position, the control module controls the rotary drive mechanism to close, thereby realizing the regulation of the state of the entry / exit channel 111 and meeting various user needs.

[0055] Optionally, the second transmission assembly includes a second driving wheel and a third driven wheel. The output end of the rotary drive mechanism is connected to the second driving wheel, and the second driving wheel meshes with the third driven wheel. The limit plug 3 is disposed on the third driven wheel. When it is necessary to rotate the limit plug 3, the control module controls the rotary drive mechanism to start. Then, the output end of the rotary drive mechanism will drive the second driving wheel to rotate, which in turn drives the third driven wheel to rotate. Since the limit plug 3 is disposed on the third driven wheel, the limit plug 3 will rotate with the third driven wheel, thereby realizing the switching of the position of the limit plug 3.

[0056] In other embodiments, the second transmission component may also include a fourth driven wheel, in which case the limiting plug 3 is disposed on the fourth driven wheel, and the third driven wheel meshes with the fourth driven wheel. Alternatively, the limiting plug 3 may be directly connected to the output end of the rotary drive mechanism.

[0057] For example, the rotary drive mechanism includes a rotary motor.

[0058] Optionally, the pet gate also includes an identification module. The identification module is communicatively connected to the control module and is configured to identify the identification device on the pet, thereby determining the pet's identity. By setting the identification module, the pet's identity can be automatically identified, and the identification result can be sent to the control module. The control module can then control the rotation drive mechanism to start based on the identification result, thereby achieving rotational switching of the limit plug 3 position. This facilitates flexible control of the state of the entry / exit channel 111, meeting various user needs.

[0059] Optionally, the pet door also includes a first magnet and a second magnet. A first magnet is provided on the side of the door frame assembly 1 facing the door panel 2, and a second magnet is provided on the side of the door panel 2 facing the door frame assembly 1. The first magnet and the second magnet attract each other, causing the door panel 2 to adhere to the door frame assembly 1. By providing the first magnet and the second magnet, the door panel 2 can be adhered to the door frame assembly 1, preventing the door panel 2 from shaking freely and ensuring that the door panel 2 always covers the entrance / exit passage 111. This enhances the tightness of the connection between the door panel 2 and the door frame assembly 1, preventing outdoor debris from entering the room through the gap between the door panel 2 and the door frame assembly 1.

[0060] like Figure 1 and Figure 2 As shown, the two corners of the door panel 2 near the limit plug 3 are rounded. By setting the two corners of the door panel 2 to rounded corners, it is possible to prevent the sharp corners of the door panel 2 from scratching the pet when the pet pushes the door panel 2 to turn, and at the same time, it can also reduce the user's bumps and collisions, and improve safety.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
