[0020] The application of the technical solution of this utility model has at least the following beneficial effects:
[0021] (1) This utility model provides an auxiliary device for pets to open and close doors automatically. It features a grab plate for pets to open doors independently, and an elastic component for automatic closing, facilitating automatic closing. Furthermore, on the side of the door panel away from the grab plate, the pet can push the door open in reverse by using its head, and the elastic component enables the door to close automatically after the pet opens in reverse. Therefore, this utility model solves the problems of damage to the door structure and energy waste caused by keeping the door open for extended periods, which are common in the prior art. Specifically, the elastic component uses an elastic rope connected to a capsule-type connector to form a closed-loop elastic rope, facilitating connection to the first and second mounting seats. The closed-loop elastic rope is in a tensioned state, providing tension for automatic closing. Additionally, this utility model has the advantages of simple structure, easy installation, and no impact on door locking.
[0022] (2) The capsule-type connector used in this utility model includes a hollow capsule shell. The first through hole and the second through hole at both ends of its length direction facilitate the two ends of the elastic rope to pass through the capsule-type connector respectively. Then, the two ends of the elastic rope are tied at the window on the side of the capsule-type connector to prevent the two ends of the elastic rope from coming out of the first through hole and the second through hole, thus realizing the connection between the elastic rope and the capsule-type connector to form a stable closed loop elastic rope.
[0023] (3) The grabbing plate used in this utility model includes a connected flat plate and a curved plate. The curved plate is set on the end of the flat plate near the door opening and closing position, and its bending direction is opposite to the door opening direction. The curved plate provides a force point for the pet to open the door, making it easy for the pet to grab the curved plate, pry open the door, and complete the door opening action. It is in line with the pet's door opening habits in use.
[0024] (4) In the first mounting base, the end face dimensions of both the first base and the first top seat are larger than the end face dimensions of the first connecting post, which facilitates the stable confinement of one end of the closed-loop elastic rope on the first connecting post, preventing the closed-loop elastic rope from detaching from the first mounting base. In the second mounting base, the end face dimensions of both the second base and the second top seat are larger than the end face dimensions of the second connecting post, which facilitates the stable confinement of the other end of the closed-loop elastic rope on the second connecting post, preventing the closed-loop elastic rope from detaching from the second mounting base. By changing the number of turns of the closed-loop elastic rope wrapped around the first and second connecting posts, the tension of the closed-loop elastic rope can also be adjusted, improving the automatic closing effect.
[0025] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0038] Example 1:
[0039] See Figures 1-6 An aid for pets to open and close doors automatically, comprising a scratching plate 1 for pets to open doors and a spring-loaded component 2 for pets to close doors automatically;
[0040] The grab plate 1 can be detachably installed on one side of the door A in the opening direction;
[0041] The elastic component 2 is detachably installed on one side of the door A in the closing direction, and its two ends are detachably installed on the door A and the door frame B of the door A, respectively. The elastic component 2 includes a first mounting base 2.1, a second mounting base 2.2, an elastic rope 2.3, and a capsule-type connector 2.4. The first mounting base 2.1 is detachably installed on the door A. The second mounting base 2.2 is detachably installed on the door frame B of the door A. The two ends of the elastic rope 2.3 are connected to the capsule-type connector 2.4 to form a closed-loop elastic rope. One end of the closed-loop elastic rope is connected to the first mounting base 2.1, and the other end is connected to the second mounting base 2.2. The closed-loop elastic rope is in a tensioned state to facilitate the provision of tension to achieve automatic door closing. This embodiment 1 incorporates a scratching post 1 for pets to open the door independently, facilitating self-opening; and a spring-loaded component 2 for automatic closing, enabling automatic closing. Furthermore, on the side of the door panel away from the scratching post, the pet can push the door open in the opposite direction using its head, and the spring-loaded component 2 ensures the door closes automatically after the pet opens it in the opposite direction. Therefore, this embodiment solves the problems in the prior art where allowing pets to freely enter and exit the room leads to structural damage to door A and energy waste due to prolonged opening of door A.
[0042] The capsule-shaped connector 2.4 includes a hollow capsule-shaped shell; a first through hole 2.4.1 and a second through hole 2.4.2 communicating with the interior of the shell are respectively provided at both ends of the capsule-shaped shell along its length, so that both ends of the elastic rope 2.3 can pass through the capsule-shaped connector 2.4 respectively; a window 2.4.3 communicating with the interior of the shell is provided on one side of the capsule-shaped shell along its length, so that both ends of the elastic rope 2.3 can be knotted respectively, preventing the two ends of the elastic rope 2.3 from coming out of the first through hole 2.4.1 and the second through hole 2.4.2, that is, the elastic rope 2.3 and the capsule-shaped connector 2.4 are connected to form a stable closed-loop elastic rope.
[0043] The grab plate 1 comprises an integrally connected flat plate 1.1 and a curved plate 1.2. The flat plate 1.1 is detachably mounted on the door panel on the side of the door A facing the opening direction (specifically, on the flat surface of the door panel of door A). The curved plate 1.2 is located on the end of the flat plate 1.1 near the door edge of door A, and its bending direction is opposite to the opening direction of door A. The curved plate 1.2 provides a force point for the pet to open the door, making it easier for the pet to grab the curved plate 1.2, pry open door A, and complete the door opening action. Its use conforms to the pet's door-opening habits.
[0044] The pet-assisted door opening and closing device also includes multiple adhesive layers (specifically double-sided adhesive layers, not shown in the figure); the adhesive layers are provided between the grab plate 1 and the door A, between the first mounting base 2.1 and the door A, and between the second mounting base 2.2 and the door frame B.
[0045] The first mounting base 2.1 includes a first base, a first connecting post, and a first top seat; both ends of the first connecting post are connected to the first base and the first top seat respectively; the end face dimensions of the first base and the first top seat are both larger than the end face dimensions of the first connecting post, so that one end of the closed-loop elastic rope is stably limited on the first connecting post, and the closed-loop elastic rope is prevented from detaching from the first mounting base 2.1.
[0046] The first base is a circular base; the first top seat is an elliptical top seat.
[0047] The second mounting base 2.2 includes a second base, a second connecting post, and a second top seat; the two ends of the second connecting post are respectively connected to the second base and the second top seat; the end face dimensions of the second base and the second top seat are both larger than the end face dimensions of the second connecting post, so that the other end of the closed-loop elastic rope is stably limited on the second connecting post, and the closed-loop elastic rope is prevented from detaching from the second mounting base 2.2.
[0048] The second base is a circular base; the second top is an elliptical top.
[0049] Example 2:
[0050] Unlike Example 1, see [link to Example 1] Figures 7-9 The grab plate 1 has a new structure, and the flat plate 1.1 is attached to the door panel on one side of the door A in the opening direction by a double-sided adhesive layer, specifically on the side of the door panel of door A at the opening and closing position; the thickness of the flat plate 1.1 is less than the gap between the door A and the door frame B.
[0051] The operating principle of the pet-assisted door opening and closing device described in Examples 1 and 2 is the same. Specifically:
[0052] The scratching plate 1 provides a force point for the pet to open the door on its own, making it easier for the pet to open the door on its own; the tension force provided by the elastic component 2 enables the door to close automatically; in addition, on the side of the door panel away from the scratching plate, the pet can push the door with its head to achieve the effect of the pet opening the door in the opposite direction, and the elastic force of the elastic component 2 enables the door to close automatically after the pet opens the door in the opposite direction.
[0053] In addition, the tension of the closed-loop elastic rope can be adjusted by changing the number of turns it makes around the first and second connecting posts, thus improving the automatic closing effect.
[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
