[0034] Reference Figures 1 to 5The foldable door frame of the embodiment of the present invention includes a first upright pole 100 and two side frame assemblies 200. The two side frame assemblies 200 are arranged at intervals along the front-to-back direction. The side frame assemblies 200 include a second upright 210 and a connecting frame 220. The second upright 210 is arranged on the first upright 100 through the corresponding connecting frame 220. The connecting frame 220 includes a first connecting beam 221 and a second connecting beam 222. One end of the first connecting beam 221 is rotatably connected to the first upright 100, one end of the second connecting beam 222 is rotatably connected to the corresponding second upright 210, and the other end of the first connecting beam 221 is rotatably connected to the other end of the corresponding second connecting beam 222; wherein the side frame assemblies 200 have an unfolded state and a folded state; in the unfolded state, the first upright 100, the first connecting beam 221, the second connecting beam 222 and the second upright 210 are arranged in sequence along the left-right direction, and a door leaf accommodating position is formed between the two side frame assemblies 200; in the folded state, the first upright 100, the first connecting beam 221, the second connecting beam 222 and the second upright 210 are overlapped with each other.

[0035] During production, the door frame is pre-assembled and is in a folded state. At this time, the first vertical pole 100, the second vertical pole 210, the first connecting beam 221 and the second connecting beam 222 are stacked on each other, thereby occupying a smaller storage and transportation space and reducing storage and transportation costs; the door frame is deformed and switched to an expanded state when installed and used on site by the user, and is connected to other structures of the door. The door leaf accommodating position can be used to accommodate the door leaf when the door is opened, and there is no need to assemble the door frame on site, thereby improving the user's installation efficiency.

[0036] In this embodiment, one end of the first connecting beam 221 is disposed in the front-to-back direction relative to the rotation axis of the first upright 100, and one end of the second connecting beam 222 is disposed in the front-to-back direction relative to the rotation axis of the second upright 210. When the side frame assembly 200 is deployed, the other end of the first connecting beam 221 is disposed in the vertical direction relative to the rotation axis of the other end of the second connecting beam 222. When the connecting frame 220 is folded, the first upright 100, the second upright 210, the first connecting beam 221, and the second connecting beam 222 are stacked, minimizing storage and transportation space.

[0037] Specifically, when the door frame is in the unfolded state and switched to the folded state, first the other end of the second connecting beam 222 is rotated relative to the other end of the first connecting beam 221, so that the first connecting beam 221 and the second connecting beam 222 are overlapped, and at this time the first vertical pole 100 is also overlapped with the second vertical pole 210; then the first connecting beam 221 and the second connecting beam 222 are rotated relative to the first vertical pole 100 and the second vertical pole 210, so that the first connecting beam 221 is overlapped on the first vertical pole 100, and the second connecting beam 222 is overlapped on the second vertical pole 210, completing the folding of the door frame. The folded door frame is approximately strip-shaped, which can save storage and transportation space to the greatest extent.

[0038] When the door frame is in the folded state and switched to the unfolded state, the first connecting beam 221 and the second connecting beam 222 are first rotated and unfolded relative to the first vertical rod 100 and the second vertical rod 210, and then the second connecting beam 222 is rotated and unfolded relative to the first connecting beam 221 to complete the unfolding process of the door frame.

[0039] Specifically, the two second connecting beams 222 rotate in opposite directions relative to the corresponding first connecting beams 221. That is, when the door frame is folded, one of the second connecting beams 222 rotates clockwise, while the other second connecting beam 222 rotates counterclockwise. Correspondingly, when the door frame is unfolded, one of the second connecting beams 222 rotates counterclockwise, while the other second connecting beam 222 rotates clockwise.

[0040] It is conceivable that in other embodiments, the door frame can be folded in other ways. For example, the rotation axis of one end of the first connecting beam 221 and the first upright 100, the rotation axis of one end of the second connecting beam 222 and the second upright 210, and the rotation axis of the other end of the first connecting beam 221 and the other end of the second connecting beam 222 are all arranged in the front-to-back direction. It can also be achieved that when folding, the first upright 100, the second upright 210, the first connecting beam 221 and the second connecting beam 222 are overlapped with each other.

[0041] In this embodiment, the connecting frame 220 further includes a locking mechanism 224 disposed between the first connecting beam 221 and the second connecting beam 222. When the side frame assembly 200 is in the deployed state, the locking mechanism 224 can lock or unlock the position of the first connecting beam 221 relative to the second connecting beam 222. The provision of the locking mechanism 224 prevents the risk of accidental folding of the door frame when it is installed and used in the deployed state, and also enhances the structural strength of the door frame in the deployed state.

[0042] In an embodiment, a hinge 223 is provided between the first connecting beam 221 and the second connecting beam 222, the locking mechanism 224 includes a latch 2241 and a pin hole 2242, the hinge 223 includes a first page plate and a second page plate, the first page plate is provided at the other end of the first connecting beam 221, the second page plate is provided at the other end of the second connecting beam 222, one end of the first page plate is pivotally connected to one end of the second page plate, the other end of the first page plate and the other end of the second page plate are both provided with pin holes 2242, and when the side frame assembly 200 is in the expanded state, the latch 2241 is inserted into the two pin holes 2242.

[0043] The first connecting beam 221 and the second connecting beam 222 are rotatably connected via a hinge 223, which is simple and easy to implement. A pin hole 2242 is provided on the hinge 223, which cooperates with a latch 2241 to lock when plugged in and unlock when pulled out, making it easy and convenient to use. Specifically, the latch 2241 and the hinge 223 are both made of metal, and the hinge 223 is secured to the first connecting beam 221 and the second connecting beam 222 by screws.

[0044] It is conceivable that the first connecting beam 221 can also be rotatably connected to the second connecting beam 222 in other ways, such as using a hinge connection, or directly setting an axial hole in the first connecting beam 221 and a rotating shaft in the second connecting beam 222, and the rotating shaft is rotatably passed through the axial hole to complete the rotational connection between the two; the locking mechanism 224 can also be other structures, for example, the locking mechanism 224 is a strip plate and two bolt and nut pairs, one end of the strip plate is locked to the first connecting beam 221 by a bolt and nut pair, and when the door frame is in the expanded state, the other end of the strip plate is locked to the second connecting beam 222 by another bolt and nut pair to complete the locking; when one of the bolt and nut pairs is removed, the unlocking is completed.

[0045] In this embodiment, the side frame assembly 200 includes four first connecting beams 221 and an equal number of second connecting beams 222. The first connecting beams 221 correspond to each second connecting beam 222 in a one-to-one manner, and all first connecting beams 221 are arranged in a vertically spaced arrangement. The four first connecting beams 221 and second connecting beams 222 arranged vertically in each side frame assembly 200 enhance the structural strength between the first upright 100 and the second upright 210, thereby increasing the structural strength and durability of the door frame in the deployed state. Furthermore, the one-to-one rotational connection between the first connecting beams 221 and the second connecting beams 222 reduces manufacturing complexity.

[0046] It is conceivable that, in other embodiments, each side frame assembly 200 may also include other numbers of first connecting beams 221 and second connecting beams 222. For example, the number of first connecting beams 221 and second connecting beams 222 of each side frame assembly 200 is two, three or more than four. Those skilled in the art may make specific configurations according to actual needs.

[0047] In the embodiment, when the side frame assembly 200 is in the deployed state, the first connecting beam 221 and the second connecting beam 222 are both arranged in the left-right direction, resulting in a larger volume of the door frame in the deployed state, meeting conventional usage requirements. It is understood that in other embodiments, when the door frame is in the deployed state, the first connecting beam 221 and the second connecting beam 222 may also be arranged at an angle relative to the left-right direction, as long as they can connect the first upright 100 and the second upright 210.

[0048] In this embodiment, a first rotation stop 2211 is provided at one end of the first connecting beam 221, and a second rotation stop 2221 is provided at one end of the second connecting beam 222. When the side frame assembly 200 is deployed, the first rotation stop 2211 abuts against the first upright 100 and restricts downward rotation of the first connecting beam 221, while the second rotation stop 2221 abuts against the second upright 210 and restricts downward rotation of the second connecting beam 222. The first rotation stop 2211 and the second rotation stop 2221 are provided to prevent the first and second connecting beams 221, 222 from excessively swinging downward under the action of gravity when the door frame is deployed, thereby affecting the deployment and use of the door frame.

[0049] Specifically, the first anti-rotation portion 2211 is a right-angled block of the first connecting beam 221, and the second anti-rotation portion 2221 is a right-angled block of the second connecting beam 222. It is understandable that the first anti-rotation portion 2211 and the second anti-rotation portion 2221 can also be structures such as diagonal braces.

[0050] In the embodiment, when the side frame assembly 200 is folded, the two second uprights 210 are respectively stacked on the front and rear sides of the first upright 100, the first connecting beam 221 is stacked on the right side of the first upright 100, and the second connecting beam 222 is stacked on the right side of the second upright 210. The above-mentioned door frame can minimize its volume when folded, further saving storage and transportation costs.

[0051] In the embodiment, the first upright pole 100, the second upright pole 210, the first connecting beam 221, and the second connecting beam 222 are all made of wood to reduce material costs. It is understood that in other embodiments, the first upright pole 100, the second upright pole 210, the first connecting beam 221, and the second connecting beam 222 may also be made of other materials, such as metal or plastic.

[0052] Specifically, the first upright 100 is secured to the connecting plate 300 via screws, and one end of the first connecting beam 221 is rotatably mounted on the connecting plate 300 via a single screw, thereby achieving a rotatable connection between the first upright 100 and one end of the first connecting beam 221. Similarly, the second upright 210 is also rotatably connected to one end of the second connecting beam 222 via the aforementioned connecting plate 300. It is contemplated that in other implementations, the first upright 100 and one end of the first connecting beam 221 may also be rotatably connected via a hinge 223; similarly, the second upright 210 and one end of the second connecting beam 222 may also be rotatably connected via a hinge 223.

[0053] Specifically, the first upright pole 100 is approximately in the shape of a strip plate.

[0054] The utility model also discloses a pocket door, which adopts the above-mentioned door frame. Due to the adoption of the above-mentioned door frame, the storage and transportation costs of the pocket door are reduced, and the user's installation and use efficiency is high.

[0055] Specifically, the pocket door further includes a guide rail 400. When the door frame is in the expanded state, the guide rail 400 is partially located inside the door frame and partially located outside the door frame.

[0056] Specifically, the pocket door further includes a limiting upright rod 500 . The first upright rod 100 and the limiting upright rod 500 are located at both ends of the guide rail 400 , and the two second upright rods 210 are located on both sides of the guide rail 400 .
