[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See also Figures 1-8 A movable door gap adjustment structure includes a door frame 10, wherein grooves 110 are respectively provided on the upper and lower sides of the door frame 10, and a movable seal 20 that can move up and down relative to the door frame 10 is provided in the groove 110, and a driving component 30 is provided on the door frame 10 for driving the movable seal 20 to move up and down relative to the door frame 10.

[0030] The utility model is provided with a groove, in which a movable seal is arranged. Under the action of a driving assembly, the movable seal can move up and down to achieve a fitting seal with the ceiling rail or the floor rail, thereby improving the aesthetics of the product and meeting the needs of users.

[0031] See also Figures 1-8 The movable seal 20 is connected to a driving rod 40, which is connected to the driving assembly 30. The driving assembly 30 drives the driving rod 40 to move up and down relative to the door frame 10, thereby driving the movable seal 20 to move up and down relative to the door frame 10. In the present invention, the driving assembly 30 drives the driving rod 40 to drive the movable seal 20 to move up or down, so that the gap between the movable seal 20 and the ceiling rail 70 or the floor rail 80 is adjusted during the upward and downward movement of the movable seal 20, thereby achieving better sealing.

[0032] See also Figure 6The driving assembly 30 includes a screw rod 310 rotatably arranged on the door frame 10, and the screw rod 310 is respectively threaded with a screw rod nut 320 on the left and right sides; the driving rod 40 is hinged with two connecting rods 340 at one end close to the screw rod 310, and the two connecting rods 340 are respectively hinged to the left and right screw rod nuts 320; the door frame 10 is provided with a driving element for driving the screw rod 310 to rotate.

[0033] The screw rod 310 is divided into a first threaded end 311 and a second threaded segment 312. One screw nut 320 is threadedly connected to the first threaded end 311, and the other is threadedly connected to the second threaded segment 312. The threads of the first threaded end 311 and the second threaded segment 312 are arranged in opposite directions. This means that when the screw rod 310 rotates, it can drive the left and right screw nuts 320 to move in opposite directions. In other words, when the screw rod 310 rotates in the forward direction, it drives one screw nut 320 to move from the right and the other screw nut 320 to the left. Under this regular movement, the linkage action of the connecting rod 340 can drive the drive rod 40 to move upward or downward relative to the door frame 10.

[0034] See also Figure 6 The end of the drive rod 40 near the screw rod 310 is threadedly connected to an adjustment member 330, and two connecting rods 340 are hingedly connected to the adjustment member 330. The adjustment member 330 is used to connect the connecting rod 340 and the drive rod 40. Its threaded connection with the drive rod 40 allows for position adjustment. Rotating the adjustment member 330 according to the adjustment requirements can adjust the upward and downward movement of the adjustment member 330 relative to the drive rod 40.

[0035] See also Figure 4 The driving element is a motor 301 or a rotating crank 302 connected to the screw rod 310. According to different usage requirements, the motor 301 or the rotating crank 302 can be set to realize the electric drive screw rod 310 rotation or the manual drive screw rod 310 rotation.

[0036] See also Figure 5 An elastic component 50 is connected between the driving rod 40 and the movable seal 20. The function of the elastic component 50 is to provide a certain upper and lower elastic buffer space for the movable seal 20 to avoid hard contact between the movable seal 20 and the door frame 10, thereby preventing wear and damage or generating loud noise.

[0037] See also Figure 5The elastic component 50 includes a movable sleeve 520 connected to the movable seal 20, and the end of the driving rod 40 close to the movable seal 20 is movably inserted in the movable sleeve 520, and a spring 540 is provided in the movable sleeve 520 to abut against the driving rod 40; a limiting pin 530 is provided on the movable sleeve 520, and a limiting groove 410 is provided at the end of the driving rod 40 close to the movable sleeve 520, and the limiting pin 530 is movably inserted in the limiting groove 410, and the driving rod 40 is arranged to move up and down relative to the limiting pin 530.

[0038] In the above embodiment, the spring 540 is disposed within the movable sleeve 520. In this state, the spring 540 applies a force to the movable sleeve 520 with the drive rod 40 as a fulcrum, causing the movable seal 20 to fit against the ceiling rail 70 or the floor rail 80. The engagement of the limit pin 530 with the limit groove 410 constrains the relative position of the movable sleeve 520 and the drive rod 40, preventing the drive rod 40 from disengaging from the movable sleeve 520.

[0039] See also Figure 5 The elastic component 50 further includes a hinged seat 510 connected to the movable seal 20, and the movable sleeve 520 is hingedly connected to the hinged seat 510. The hinged arrangement allows the movable seal 20 to have a certain amount of left and right adjustment space during assembly, facilitating assembly and adjustment and meeting assembly requirements.

[0040] See also Figure 5 The upper and lower sides of the door frame 10 are respectively provided with guide sleeves 60 , the guide sleeves 60 are fixedly provided on the door frame 10 , and the movable sleeve 520 is movably inserted into the guide sleeve 60 .

[0041] See also Figures 1 to 4 A cross bar 120 is provided in the door frame 10 . The cross bar 120 is hollow inside. The driving assembly 30 is provided inside the cross bar 120 .

[0042] See also Figure 3 and Figure 4 The movable seal 20 is provided with a guide shaft 210 , and the guide shaft 210 is movably connected with the door frame 10 to achieve guidance.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
