Detailed Implementation

[0027] To achieve the above objectives, this utility model provides a door structure, such as... Figures 1 to 3 As shown, Figure 1 This is a front view of the door structure in the embodiment of this application; Figure 2 for Figure 1 A cross-sectional view of region A along the first direction; Figure 3 for Figure 1 A cross-sectional view of region B along the second direction.

[0028] The door structure includes a door body 101 with a door opening, the door opening penetrating two door walls of the door body 101 along its thickness direction. The door structure also includes a frame portion 103 and a sub-door body 102 hinged to the frame portion 103; the frame portion 103 includes a first petal portion 103a and a second petal portion 103b arranged around the door opening, one end of the first petal portion 103a and the second petal portion 103b pressing against the corresponding door wall along their thickness direction; the other end abuts against the inside of the door opening.

[0029] The main door 101 is for people to pass through, the doorway is for pets to pass through, and the sub-door 102 is used to open and close the doorway. The sub-door 102 is connected to the doorway via a frame 103. The frame 103 includes an interlocking first petal 103a and a second petal 103b, which surround the doorway and wrap around its edges to prevent pets from rubbing against the doorway while passing through.

[0030] The first petal 103a and the second petal 103b can be made of lightweight and durable materials, such as thermoplastic extrusion or injection molding.

[0031] By adopting the technical solution of this application, a doorway is opened in the door body 101 for pets to pass through, and a sub-door body 102 is provided in the doorway to close the doorway. The frame 103 is provided with interlocking first petal 103a and second petal 103b, which facilitates the installation, maintenance and replacement of the frame 103. The first petal 103a and second petal 103b can also be connected by threaded connection, snap-fit, glued connection, etc., all of which are within the protection scope of this application.

[0032] In some embodiments, the first petal portion 103a and the second petal portion 103b form a cavity portion 103c, and the opening has a wall portion 101a located within the cavity portion 103c. It also includes a transition portion located within the cavity portion 103c, a portion of which abuts against at least one of the first petal portion 103a and the second petal portion 103b, and another portion of which abuts against the wall portion 101a.

[0033] As shown in the figure, the outer surfaces of the first petal 103a and the second petal 103b transition to an arc shape, forming a cavity 103c. The wall 101a of the doorway is located within the cavity 103c and is enclosed by the first petal 103a and the second petal 103b. A connecting part is disposed within the cavity 103c and connects to the wall 101a of the doorway, as well as to the cavity 103c itself, and can connect to the first petal 103a.

[0034] In this way, the frame 103 and the door body 101 can be further connected, improving the connection strength between the frame 103 and the door body 101. At the same time, the transition part also serves as an installation limit, ensuring the installation accuracy of the frame 103 and the door opening.

[0035] In other embodiments, the first lobe 103a has a stepped structure, and the stepped surface 103a-1 of the stepped structure extends in a direction perpendicular to the wall portion 101a; the transition portion includes a first transition arm 104a and a second transition arm 104b that are perpendicular to each other, the first transition arm 104a is in contact with the stepped surface 103a-1, and the second transition arm 104b is in contact with the wall portion 101a.

[0036] The adapter is a plate-like structure, with the first adapter arm 104a and the second adapter arm 104b arranged vertically. The first adapter arm 104a is fitted against and connected to the step surface 103a-1. The second adapter arm 104b is fitted against and connected to the wall portion 101a. Connections can be made using threaded connections, riveting, adhesive bonding, or other methods.

[0037] This increases the contact area between the transition part and the door opening and the first petal 103a. During daily use, the stress on the frame 103 can be transferred to the door body 101 through the transition part, thereby preventing the frame 103 from shifting after long-term use.

[0038] In some other embodiments, a stop portion 103a-2 is also included, which is located inside the cavity 103c and is disposed on the first flap portion 103a; the stop portion 103a-2 abuts against the wall portion 101a.

[0039] The stop portion 103a-2 is a stop structure provided on the first petal portion 103a, used to abut against the wall portion 101a in a direction perpendicular to the wall portion 101a. This can limit the movement of the first petal portion 103a and the wall portion 101a during installation, thereby further ensuring the installation accuracy of the first petal portion 103a.

[0040] In some embodiments, a locking part is also provided on the frame portion 103. The locking part has a locking bar portion 105a and a locking tongue portion that engages with the locking bar portion 105a to prevent rotation. The locking tongue portion is located in the cavity portion 103c. The locking tongue portion has two locking arms 105b, which are spaced apart along the axial direction of the locking bar portion 105a and are staggered in the circumferential direction of the locking bar portion 105a. The frame portion 103 is provided with an opening 103d, through which portions of the locking arms 105b can extend and abut against the surface of the corresponding side of the sub-door body 102.

[0041] The locking lever 105a and the latch can be connected by a key to form a circumferential anti-rotation mechanism, allowing the latch to rotate by turning the locking lever 105a. The latch includes two locking arms 105b. One locking arm 105b extends through the opening 103d and abuts against one side of the sub-door body 102 in the thickness direction of the door body 101. The other locking arm 105b extends through the opening 103d and abuts against the other side of the sub-door body 102.

[0042] In this way, the user can switch the opening direction of the sub-door 102 by rotating the locking lever 105a, thereby locking the sub-door 102. Of course, it can also be rotated until both locking arms 105b are retracted into the cavity 103c, at which point the sub-door 102 can be opened freely in both directions.

[0043] In this way, the user can choose to lock the sub-gate 102 in a single direction.

[0044] In this embodiment, the locking bar portion 105a has two ends, which are located on the side of the frame portion 103 away from the cavity portion 103c.

[0045] One end of the locking lever 105a is located indoors, and the other is located outdoors. This allows the user to operate the locking mechanism from either indoors or outdoors.

[0046] In other embodiments, the door structure further includes a pivot 106 hinged to the frame portion 103 and the sub-door 102; the central axis of the pivot 106 is perpendicular to the extending direction of the central axis of the locking rod portion 105a.

[0047] By hinged to the sub-door 102, the opening and closing of the sub-door 102 can be facilitated. The axial direction of the hinge 106 extends along the width or length direction of the door opening. The central axis of the locking rod 105a extends along the thickness direction of the door opening. This optimizes the opening and closing performance of the sub-door 102 and improves the convenience of installation and maintenance.

[0048] Optionally, the sub-gate body 102 is a rectangular structure, with the corners of the rectangular structure having an arc transition; the two corners are hinged to the corresponding pivot 106.

[0049] By hinged the sub-door 102 to the pivot 106 at the corner of the rectangle, damage to the sub-door 102 and the frame 103 can be avoided, thus improving the structural strength of the frame 103. This also ensures sufficient space for the pet to pass through.

[0050] The sub-door body 102 is formed with a hinged mounting groove for hinged connection with the rotating shaft 106 by injection molding. A damping structure can also be set in the mounting groove to improve the smoothness of opening and closing of the sub-door body 102 and reduce the noise generated during the opening and closing of the sub-door body 102.

[0051] In other embodiments, a sealing ring 107 is also fitted around the edge of the sub-door body 102. The sealing ring 107 can contact the frame portion 103, thereby sealing the door opening and enhancing airtightness and sound insulation performance.

[0052] In the various embodiments described above, the sub-door 102 can adopt a gradient from top to bottom, from opaque to transparent, thereby taking into account the safety needs of pets when passing through the doorway, while reducing the overall light transmittance of the sub-door 102.

[0053] Compared with related technologies, the advantages of this application are:

[0054] First, by adopting the technical solution in this application, a doorway is opened in the door body 101 for pets to pass through, and a sub-door body 102 is provided in the doorway so that the doorway can be closed. The frame 103 is provided with a first lobe 103a and a second lobe 103b that interlock, so as to facilitate the installation, maintenance and replacement of the frame 103.

[0055] Secondly, it enables further connection between the frame 103 and the door body 101, improving the connection strength between them. Simultaneously, the adapter also serves as an installation limit, ensuring the installation accuracy of the frame 103 and the door opening.

[0056] Third, it can further increase the contact area between the transition part and the door opening and the first petal 103a. During daily use, the stress on the frame 103 can be transmitted to the door body 101 through the transition part, thereby preventing the frame 103 from shifting after long-term use.

[0057] Fourth, this can limit the position of the first petal 103a and the wall 101a during installation, thereby further ensuring the installation accuracy of the first petal 103a.

[0058] Fifth, the user can switch the opening direction of the sub-door 102 by rotating the locking lever 105a to lock the sub-door 102. Of course, it can also be rotated until both locking arms 105b are retracted into the cavity 103c, at which point the sub-door 102 can be opened freely in both directions.
