Description

Technical Field

[0001] This application relates to the field of pet door technology, and more particularly to a pet door. Background Technology

[0002] With the increasing number of pets in households, pet doors, as a convenient device, have been widely used in residential homes and outdoor spaces. Most common pet doors are recessed, installed in existing doors or walls, and are of moderate size, allowing small animals to pass through freely.

[0003] Currently, pet doors can be broadly categorized into two types based on existing technology: mechanical and electronically controlled. Mechanical pet doors typically employ a flap or sliding structure, relying on the pet to push the door open for passage; some products are equipped with a simple magnetic closing device to enhance convenience and safety.

[0004] However, mechanical pet doors use a one-way or sliding switch structure and lack an effective two-way locking mechanism. This makes it impossible to flexibly control the opening and closing of the door according to actual usage scenarios, resulting in poor safety and environmental isolation. Pets' activities are complex, and the inability to reliably control the opening and closing of the door can easily cause it to get stuck or break, potentially rendering the pet unable to continue using it or causing injury in the process. Utility Model Content

[0005] In view of this, it is necessary to provide a pet door that can better lock the door to prevent pets from colliding and getting injured, in order to solve the above problems.

[0006] An embodiment of this application provides a pet door, including a frame and a door body disposed on the frame;

[0007] The locking assembly includes a first locking member and a second locking member. The door body has a rotating end and an opening and closing end that are disposed opposite to each other. The first locking member is disposed on the side of the door body near the opening and closing end. When the door body is attached to the frame, the first locking member partially extends into the frame to lock or extends out of the frame to unlock.

[0008] The rotating end is located on the frame and connected to the frame's pivot. The second locking member is located on the side of the door body near the rotating end. When the door body is opened, the second locking member moves to abut against the frame to support the door body in the open state.

[0009] In at least one embodiment of this application, a guide groove is provided on the side of the door body near the opening end, and the first locking member extends out of the guide groove.

[0010] The frame has a locking groove. When the door body fits into the frame, the locking groove is directly opposite the guide groove. The guide groove extends inward from the side near the door body to form a stop. The first locking member extends into the locking groove and abuts against the stop to lock the frame.

[0011] In at least one embodiment of this application, the door body includes a first door panel and a second door panel that overlap each other, and the first locking member is disposed between the first door panel and the second door panel;

[0012] The door also includes a positioning part, which is disposed on the second door panel and engages with the first locking member to position the first locking member.

[0013] In at least one embodiment of this application, the first locking member includes a body and an engaging portion and a first locking portion disposed on the body. The body is disposed between the first door panel and the second door panel, and the first locking portion extends into the locking groove to lock the frame.

[0014] One end of the engaging portion is provided on the body, and the other end extends outward. A deformation cavity is formed between the engaging portion and the body, and the deformation cavity is located on the side of the engaging portion away from the positioning portion.

[0015] In at least one embodiment of this application, the first locking member further includes a pushing portion, wherein the pushing portion has a first pushing cavity and a second pushing cavity arranged side by side, which are recessed inward at opposite ends, and the openings of the first pushing cavity and the second pushing cavity are arranged in opposite directions.

[0016] In at least one embodiment of this application, the door body and the frame are respectively provided with a first through hole and a second through hole on the side near the rotating end, and the second locking member includes a fixing part and a second locking part disposed on the fixing part, and the fixing part is rotatably disposed on the door body along its axis;

[0017] When the door is opened to be parallel to the frame, the first through hole is aligned with the second through hole, and rotating the fixing part causes the second locking part to extend into the second through hole.

[0018] In at least one embodiment of this application, the first door panel extends toward the second door panel to form a limiting block, the limiting block being located on the side of the second door panel near the opening end, and when the second locking member is unlocked, the limiting block abuts against the second locking member.

[0019] In at least one embodiment of this application, the locking assembly further includes a first magnetic element and a second magnetic element. The first magnetic element is disposed in the door body, and the second magnetic element is disposed in the second locking part. When the second locking part is rotated to unlock, the first magnetic element attracts the second magnetic element to fix the second locking part.

[0020] In at least one embodiment of this application, the frame includes a first frame having a pet passage and a second frame disposed on the first frame, the first frame and the second frame forming a fixing groove, the fixing groove engaging with a wall to fix the frame, and the first frame being connected to the door hinge.

[0021] In at least one embodiment of this application, the pet door further includes a flexible curtain with a fixing hole, the fixing groove sidewall extending outward to form a fixing post, the fixing hole being fitted onto the fixing post, and the flexible curtain covering the pet passage.

[0022] The pet door provided above uses a first locking element and a second locking element to lock and control the opening and closing end and the rotating end of the door body respectively. It can flexibly set the opening or closing state of the door body according to different usage scenarios. When the door body is open, the second locking element can form abutment support with the frame, effectively keeping the door body in the open state and preventing the door body from automatically closing due to wind, human collision or pet collision. This helps to prevent pets from being caught in the door or feeling fear and anxiety during the process of entering and exiting, and improves the safety and comfort of pet passage.

[0039] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0040] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0041] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] Please see Figures 1-14 An embodiment of this application provides a pet door 100, comprising:

[0043] Frame 10 and door 20 disposed on the frame 10;

[0044] The locking assembly 30 includes a first locking member 31 and a second locking member 32. The door body 20 has a rotating end 21 and an opening and closing end 22 that are disposed opposite to each other. The first locking member 31 is disposed on the side of the door body 20 near the opening and closing end 22. When the door body 20 is attached to the frame 10, the first locking member 31 partially extends into the frame 10 to lock or extends out of the frame 10 to unlock.

[0045] The rotating end 21 is disposed on the frame 10 and connected to the rotating shaft of the frame 10. The second locking member 32 is disposed on the side of the door 20 near the rotating end 21. When the door 20 is opened, the second locking member 32 is moved to abut against the frame 10 to support the door 20 to remain open.

[0046] Specifically, frame 10 is a fixed support component of the overall structure, typically installed on a wall or door 20, used to define the boundary for pet passage; door 20 is the movable part that can be opened and closed, hinged to frame 10. A first locking member 31 located near the opening / closing end 22 of door 20 can partially extend into the locking groove 11 within frame 10 to form a locked state when door 20 is against frame 10, achieving mechanical limitation between door 20 and frame 10; when the first locking member 31 exits frame 10, door 20 is unlocked and enters an openable state. This structure, in conjunction with the locking groove 11 of frame 10, forms an effective closing locking mechanism.

[0047] Furthermore, a second locking element 32 is provided near the rotating end 21 of the door body 20. When the door body 20 is rotated open to a certain angle, the second locking element 32 can move to contact the frame 10, forming a stable support, so that the door body 20 remains stationary in the open state, preventing automatic rebound or free swinging. The first locking element 31, the second locking element 32 and the rotating structure of the door body 20 work together to form a complete actuation process of closing and locking - opening - opening support - re-closing.

[0048] In one specific embodiment, a guide groove 23 is provided on the side of the door body 20 near the opening end 22, and the first locking member 31 extends out of the guide groove 23.

[0049] The frame 10 has a locking groove 11. When the door 20 is attached to the frame 10, the locking groove 11 is directly opposite the guide groove 23. The guide groove 23 extends inward on the side near the door 20 to form a stop part 231. The first locking member 31 extends into the locking groove 11 and abuts against the stop part 231 to lock the frame 10.

[0050] Specifically, a guide groove 23 is provided on one side of the opening and closing end 22 of the door body 20, and the first locking member 31 is partially embedded in the guide groove 23 to form a movable fitting structure. The guide groove 23 provides an active guiding path for the first locking member 31 and at the same time constrains its active direction to prevent the locking member from deviating or falling off, thereby improving its stability during the opening and closing process.

[0051] Furthermore, the locking groove 11 provided on the frame 10 aligns with the guide groove 23 when the door 20 is closed, so that the first locking member 31 can be smoothly inserted into the locking groove 11. Through the alignment and cooperation between the guide groove 23 and the locking groove 11, the insertion action between the first locking member 31 and the frame 10 is accurately completed, realizing fast and accurate locking / unlocking behavior and enhancing the closing accuracy.

[0052] Furthermore, a stop portion 231 is formed at one end of the guide groove 23, which serves as a blocking surface after the first locking member 31 is inserted. When the first locking member 31 is inserted into the locking groove 11, its tail end abuts against the stop portion 231, effectively preventing loosening or retraction caused by external force, and further improving locking strength and impact resistance.

[0053] In one specific embodiment, the door body 20 includes a first door panel 24 and a second door panel 25 that overlap each other, and the first locking member 31 is disposed between the first door panel 24 and the second door panel 25;

[0054] The door body 20 also includes a positioning part 26, which is disposed on the second door panel 25 and engages with the first locking member 31 for positioning the first locking member 31.

[0055] Specifically, the door body 20 adopts a two-piece cover structure, allowing the first locking member 31 to be embedded in the interlayer space between the two door panels. This clamping structure provides a closed and controlled installation space, preventing the first locking member 31 from loosening or falling off inside the door body 20. The positioning part 26 is an internal structural component of the door body 20, used to engage with the first locking member 31; through the engagement relationship, the movement of the first locking member 31 in the locking direction inside is restricted.

[0056] In one specific embodiment, the first locking member 31 includes a body 311 and a locking part 312 and a first locking part 313 disposed on the body 311. The body 311 is disposed between the first door panel 24 and the second door panel 25, and the first locking part 313 extends into the locking groove 11 to lock the frame 10.

[0057] One end of the engaging portion 312 is provided on the body 311, and the other end extends outward. A deformation cavity 314 is formed between the engaging portion 312 and the body 311. The deformation cavity 314 is located on the side of the engaging portion 312 away from the positioning portion 26.

[0058] Specifically, the main body 311, as the core component supporting the overall structure, is embedded between the first door panel 24 and the second door panel 25 to achieve a stable installation of the locking component. One end of the engaging part 312 is connected to the main body 311, and the other end extends outward, cooperating with the deformation cavity to generate elastic deformation, providing deformation response when the locking part enters the locking groove 11.

[0059] Furthermore, a deformation cavity 314 is formed between the engaging part 312 and the body 311, allowing the engaging part 312 to elastically deform relative to the body 311 when subjected to force; during the process of the door 20 closing and pushing the first locking member 31 into the locking groove 11, the engaging part 312 is squeezed by the groove wall of the frame 10 and undergoes a brief deformation, allowing the first locking part 313 to be smoothly inserted. After insertion, it automatically resets, realizing the operation process of "automatic locking + automatic restoration".

[0060] In one specific embodiment, the first locking member 31 further includes a pushing part 315, wherein the pushing part 315 has a first pushing cavity 315a and a second pushing cavity 315b arranged side by side, which are recessed inward at opposite ends. The openings of the first pushing cavity 315a and the second pushing cavity 315b are arranged in opposite directions.

[0061] Specifically, the openings of the push chambers are opposite, facing opposite sides of the first locking member 31, allowing users to freely choose to operate from either side depending on the opening direction of the door 20 or the installation environment, thus adapting to different installation directions or space limitations. The recessed design of the push chambers allows users to insert their fingers or tools into the push chambers for pressing or flicking operations, avoiding slippage of traditional flat push structures when hands are wet or angles are limited, thus enhancing the human-computer interaction experience and control.

[0062] In one specific embodiment, the door body 20 and the frame 10 are respectively provided with a first through hole 27 and a second through hole 28 on the side near the rotating end 21. The second locking member 32 includes a fixing part 321 and a second locking part provided on the fixing part 321. The fixing part 321 is rotatably provided on the door body 20 along its axis.

[0063] When the door 20 is opened to be parallel to the frame 10, the first through hole 27 is directly opposite the second through hole 28, and rotating the fixing part 321 causes the second locking part to extend into the second through hole 28.

[0064] Specifically, the first through hole 27 provides a insertion and positioning passage for the second locking member 32, ensuring that the second locking member 32 can accurately extend into the frame 10 when the door 20 is opened to a specific angle, thereby achieving mechanical support and stopping. When the door is opened to be parallel to the frame 10, by rotating the fixing part 321, the second locking part is inserted from the inside of the door 20 into the second through hole 28 of the frame 10, thereby keeping the door 20 in the open state.

[0065] Furthermore, the fixing part 321 allows the second locking member 32 to rotate around its axis, enabling the extension or retraction of the second locking part 322 through a simple manual rotation. This avoids complex spring or drive component designs, making the locking / unlocking process simple and reliable. Users can quickly and manually lock the door 20 after it is opened to prevent it from automatically springing back or swinging.

[0066] In one specific embodiment, the first door panel 24 extends toward the second door panel 25 to form a limiting block 241. The limiting block 241 is located on the side of the second door panel 25 near the opening end 22. When the second locking member 32 is unlocked, the limiting block 241 abuts against the second locking member 32.

[0067] Specifically, the limiting block 241 is integrally formed through structural extension, simplifying the number of parts and eliminating the need for an additional independent limiting device. It is located inside the door body 20, between the two door panels, and does not affect the overall appearance of the door body 20. The limiting block 241 itself does not directly lock the door body 20, but in the unlocked state, it provides a physical limiting position for the second locking member 32, preventing excessive swinging or rotational dislocation during rotation or release.

[0068] Furthermore, after the limiting block 241 is combined with the second locking member 32 located inside the door body 20, the limiting block 241 can form a natural stop structure, which not only makes the structure more compact, but also prevents users or pets from accidentally touching the locking member and causing damage or jamming.

[0069] In one specific embodiment, the locking assembly 30 further includes a first magnetic element 40 and a second magnetic element 50. The first magnetic element 40 is disposed inside the door body 20, and the second magnetic element 50 is disposed in the second locking part 322. When the second locking part 32 is rotated to unlock, the first magnetic element 40 attracts the second magnetic element 50 to fix the second locking part 322.

[0070] Specifically, the magnetic adsorption device does not affect the basic movement of the locking structure, but it can maintain the preset posture of the locking component after unlocking, preventing the structure from swinging and interfering with the door's return movement.

[0071] Furthermore, the first magnetic component 40 is embedded within the door housing 20, near the endpoint of the second locking component 32's movement. This ensures that the magnetic fixation does not affect the structural integrity of the door 20, nor is it exposed to the pet's contact surface, thus enhancing safety and durability. The second magnetic component 50 rotates and moves with the second locking component 32, acting as the active agent for magnetic adsorption. Its installation position has been structurally calibrated to ensure alignment with the first magnetic component 40 during unlocking, thereby achieving automatic alignment and adsorption.

[0072] Furthermore, after the user rotates the second locking component 32 to disengage it from the hole in the frame 10 and return it to the inner cavity of the door body 20, the magnetic component can directly fix the locking component in the unlocked position without additional operation or auxiliary structures. In conjunction with the through holes in the door body 20, the limiting block 241, and other structures, the entire process of opening or closing the door body 20 is smoother, while maintaining a compact and stable structure, thus improving overall stability.

[0073] In one specific embodiment, the frame 10 includes a first frame 12 with a pet passage and a second frame 13 disposed on the first frame 12. A fixing groove 14 is formed between the first frame 12 and the second frame 13. The fixing groove 14 engages with the wall to fix the frame 10. The first frame 12 is pivotally connected to the door 20.

[0074] Specifically, the first frame 12 and the second frame 13 provide basic passage space for pets to pass through, while the first frame 12 serves as the main load-bearing structure for the installation and rotation of the door 20. This double-layer structure gives the frame 10 good structural strength and installation adaptability, which can be flexibly adjusted according to wall thickness or different installation scenarios, improving the product's versatility.

[0075] Furthermore, a certain space is left between the two frames, and a locking groove is constructed to accommodate the wall. Through this fixing groove 14, the entire pet door frame 10 can be inserted and locked into the wall structure, achieving embedded installation by utilizing the fit between the wall thickness and the groove depth. Initial positioning and installation can be achieved without screws or glue, which is convenient and quick. The rotating hinge structure of the door 20 is set on the first frame 12, so that the door 20 can open and close smoothly around the pivot.

[0076] In one specific embodiment, the pet door further includes a flexible curtain 60, the curtain having a fixing hole 61, the fixing groove 14 extending outward to form a fixing post 141, the fixing hole 61 being fitted onto the fixing post 141, and the flexible curtain 60 covering the pet passage.

[0077] Specifically, as an additional shielding device for the door 20, it covers the pet passage and still provides isolation and protection when the door 20 is open. The flexible curtain 60 can automatically droop back to its original position after the pet passes through, and has good effects in blocking wind, dust, insects, and light interference. It can also provide partial sealing when the door 20 is not closed, improving the overall sealing performance and ease of use.

[0078] Furthermore, the fixing post 141 is integrally installed on the side wall of the fixing groove 14, which not only provides a robust structure but also does not occupy additional wall space. It provides a stable hanging position for the curtain without affecting the opening and closing of the door 20. The curtain has fixing holes 61 and is fitted onto the fixing post 141, simplifying installation and avoiding damage or difficulty in disassembly caused by using screws or adhesives. This allows users to quickly replace, clean, or adjust the curtain's position, providing a passageway for pets that is both freely accessible and slightly enclosed.

[0079] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
