[0034] Reference Figure 1 As shown, a small door that is easy to adjust and assemble includes a door body 1, a main doorpost 2, a motor assembly 3, and a secondary doorpost 4. One side of the door body 1 is rotatably mounted on the main doorpost 2. The motor assembly 3 is mounted on the top of the main doorpost 2 to drive the door body 1 to rotate. The secondary doorpost 4 cooperates with the other side of the door body 1.

[0035] Combination Figure 2 As shown, the door body 1 is composed of a door frame 101 and multiple uprights 102 installed within the door frame 101. The door frame 101 is formed by fastening together a left side frame 1011, a right side frame 1012, an upper side frame 1013, and a lower side frame 1014. The left side frame 1011 is connected to the main doorposts 2. Adjustable inserts 1016 for connecting extension frames 1015 are movably installed within the upper side frame 1013 and the lower side frame 1014. After the adjustable inserts 1016 are moved into place, they are locked and fixed by screws or bolts 1017. The right side frame 1012 is locked and fixed to the adjustable inserts 1016 by long bolts 1018 that axially penetrate the adjustable inserts 1016. Since the adjusting insert 1016 is locked and fixed inside the upper frame 1013 and the lower frame 1014 by screws or bolts 1017, and the right frame 1012 is fixed by a long bolt 1018 that passes through the adjusting insert 1016, it can achieve good connection strength even if there is no traditional interlocking structure between the right frame 1012 and the upper frame 1013 and the lower frame 1014.

[0036] To facilitate the tightening of the long bolt 1018, a through hole corresponding to the long bolt 1018 is preferably provided on the outer side of the right frame 1012. The tightening tool can pass through the through hole and rotate in both directions to operate the long bolt 1018 to tighten or loosen it. Preferably, both the upper and lower ends of the right frame 1012 are open structures. In some embodiments, only one of the upper and lower ends is an open structure. A pad 1019 is provided inside the right frame 1012, and the long bolt 1018 passes through the pad 1019.

[0037] By setting the shim plate 1019, when it is necessary to change the width of the door 1 by replacing it with a different extension frame 1015, the long bolt 1018 can be loosened by turning it with a tool. Then, the shim plate can be moved or removed to separate the right frame 1012 from the long bolt 1018 and remove it. After that, the positioning and adjusting insert 1016 is moved according to the new extension frame 1015. Finally, the new extension frame 1015 is put on and the right frame 1012 is put back on to complete the replacement of the extension frame 1015. It should be noted that the extension frame 1015 is a pre-assembled part with several different lengths. Depending on the actual needs, the extension frame can be assembled in one, two, or more sections, depending on the actual needs of the installation site. The locking element used to lock the adjusting insert 1016 is preferably a bolt. The bolt can pass through the upper and lower sides of the adjusting insert 1016, or it can be set to pass through the inner cavity of the adjusting insert 1016. When the bolt is set to pass through the inner cavity of the adjusting insert 1016, it is preferable to provide a washer with a nut in the inner cavity of the adjusting insert 1016 to cooperate with the bolt, so as to ensure the reliability and strength of the connection.

[0038] Preferably, the adjusting insert 1016 has a plurality of axially distributed strip-shaped holes, and the upper frame 1013 and the lower frame 1014 each have a plurality of axially distributed connecting holes. In this way, besides changing the position of the adjusting insert 1016 through the strip-shaped holes, the position of the adjusting insert 1016 can also be changed through the cooperation between different strip-shaped holes and connecting holes, resulting in a large adjustable range for the position of the adjusting insert 1016. In this embodiment, it is preferable that both the strip-shaped holes and the connecting holes are 2×3 array holes; the two rows of arrangement better ensure connection strength.

[0039] Furthermore, to avoid exposing screws or bolts 1017, through holes, and openings, corresponding decorative cover plates are provided on the right side frame 1012, the upper frame 1013, and the lower frame 1014. The specific installation structure of the decorative cover plates is common technical knowledge for those skilled in the art and will not be elaborated upon here.

[0040] In this embodiment, a magnetic attraction device 5 is also installed between the door body 1 and the secondary doorpost 4. The magnetic attraction device 5 helps to better seal the doorway. The specific installation structure of the magnetic attraction device 5 is common technical knowledge known to those skilled in the art and will not be described in detail here.

[0041] Combination Figure 3 , Figure 4As shown, the column 102 is connected to the upper frame 1013 and the lower frame 1014 through the column mounting cover 7. The column mounting cover 7 is provided with through holes corresponding to the column 102. The upper end and the lower end of the column 102 are respectively inserted into the corresponding through holes. The column mounting cover 7 is fastened to the upper frame 1013 through the corresponding buckle 701 and the slot 10131. The column mounting cover 7 is also fastened to the lower frame 1014 through the corresponding buckle and the slot.

[0042] The post mounting cover 7 is a pre-assembled part, available in several different lengths to suit the specific needs of the installation site. When it is necessary to replace the post 102, external force can be applied to remove the post mounting cover 7 from the upper frame 1013 and lower frame 1014. Then, the post mounting cover 7 can be moved outwards to tilt the post 102 for easy removal and replacement, making the replacement of the post 102 very convenient.

[0043] Reference Figure 5 As shown, in one embodiment, a snap-on sealing cover 6 is provided at the inner end of the extension frame 1015. The snap-on sealing cover 6 can better prevent rainwater from entering the cavities of the upper and lower door frames, and can also avoid the unsightly problem caused by exposed joint seams. The snap-on sealing cover 6 is preferably composed of two U-shaped covers that cooperate with each other and are then fixed by screws. It should be noted that, in order to avoid affecting the aesthetics, the screws can be locked from the top or bottom, rather than the front locking shown in the figure.

[0044] In one embodiment, the column 102 is an adjustable-length column. For example, the column 102 comprises upper and lower sections and a connecting seat 1023 located in the middle to connect the upper and lower sections. The upper section 1021 and / or the lower section 1022 are threadedly connected to the connecting seat 1023. When the column 102 needs to be replaced, the upper section 1021 and / or the lower section 1022 can be rotated relative to the connecting seat 1023, thereby shortening the overall length of the column 102, facilitating the removal and replacement of the column. Of course, the adjustable-length structure of the column 102 is not limited to the above example. Those skilled in the art can also use other known or future-possible length adjustment mechanisms according to different actual needs.
