[0032] See Figures 1 to 7 and combined Figures 8-11 This utility model relates to a door gap sealing structure 100 and a door leaf using the door gap sealing structure 100. The door leaf is, for example, an aluminum alloy sliding door (including floor sliding and hanging sliding structures). By setting the door gap sealing structure 100, the gaps between the upper and lower ends of the door leaf and the external structure (such as the ground, upper and lower door frames or upper and lower tracks) are sealed, thus solving the problems of air leakage and poor sound insulation of the door leaf.

[0033] The door gap sealing structure 100 includes a sealing seat 10, a sealing strip 20, a spring strip 30, a drive assembly 40, and a limiting assembly 50.

[0034] Please combine Figure 2The sealing seat 10 is provided with a rubber strip mounting groove 12 and a spring receiving groove 11, which are respectively arranged at two ends of the sealing seat 10 along the height direction, wherein the rubber strip mounting groove 12 is T-shaped.

[0035] Please combine Figure 3 The sealing rubber strip 20 is made of flexible material and comprises a rubber strip body 21 and mounting portions 22 and sealing portions 23 connected to two sides of the rubber strip body 21, the mounting portions 22 are T-shaped and embedded in the T-shaped rubber strip mounting groove 12, the rubber strip body 21 and the sealing portions 23 are exposed to the rubber strip mounting groove 12, the sealing portions 23 are sheet-shaped and connected to the rubber strip body 21 in an eight-character shape and can be deformed under pressure.

[0036] Please combine Figures 4 to 6 The spring strip 30 is long strip-shaped and made of metal material with elasticity and restoring original shape, which comprises a mounting end 31, a first fixing portion 32 and an elastic deformation portion 33 connected between the two, the first fixing portion 32 is fixed with the sealing seat 10, and the elastic deformation portion 33 is embedded in the spring receiving groove 11 and can be deformed in an arch shape towards the sealing rubber strip 20 under force.

[0037] The driving assembly 40 and the limiting assembly 50 are connected with the mounting end 31 of the spring strip 30 and respectively arranged at two ends of the sealing seat 10 along the length direction, the driving assembly 40 can slide transversely along the length direction of the sealing seat 10 and slide towards the limiting assembly 50 when subjected to external pressure, and the limiting assembly 50 is used for fixing with the door leaf frame to limit the transverse movement of the spring strip 30, so that the elastic deformation portion 33 of the spring strip 30 is elastically deformed to push the sealing seat 10 and drive the sealing rubber strip 20 to extend from the door leaf frame along the height direction to seal the door gap when the driving assembly 40 is subjected to pressure.

[0038] The working principle of the door gap sealing structure 100 is that when the door is closed, the driving assembly 40 installed in the door leaf frame first contacts the door frame and gradually retracts into the door leaf frame (i.e. moves towards the limiting assembly 50) under the pressing of the door frame, during the closing process, the spring strip 30 has a tendency to move towards the limiting assembly 50, and since the limiting assembly 50 is fixed with the door leaf frame to limit the transverse movement of the spring strip 30, the spring strip 30 can only elastically deform in the direction of the sealing rubber strip 20, thereby pushing the sealing seat 10 and the sealing rubber strip 20 to move away from the door leaf frame, and the sealing rubber strip 20 gradually extends from the door leaf frame and finally seals the door gap.

[0039] Please combine Figure 2In one embodiment, the sealing seat 10 further includes a second fixing part 13, which is, for example, plate-shaped, fixed above the spring receiving groove 11 and has a clearance hole. The second fixing part 13 is preferably integrally formed with the sealing seat 10.

[0040] The portion of the spring strip 30 furthest from the mounting end 31 is bent into an arched structure to form the first fixing part 32. The arched structure passes through the clearance hole and is then fixed to the sealing seat 10 by a rod-like component.

[0041] Please combine Figure 4 and Figure 5 In one embodiment, the spring bar 30 is provided as one, with mounting ends 31 respectively at both ends, and the first fixing part 32 is provided between the two mounting ends 31.

[0042] As can be seen from the above embodiments, the extension amount of the sealing strip 20 is related to the deformation range of the elastic deformation portion 33. In one embodiment, two first fixing portions 32 are provided, and the two first fixing portions 32 are arranged at intervals. The elastic deformation portion 33 is formed between the first fixing portion 32 and the nearest mounting end 31. The lengths of the two elastic deformation portions 33 are equal or unequal. Thus, by providing two first fixing portions 32, a technician can adjust the spacing between the two first fixing portions 32 according to the required deformation range of the two elastic deformation portions 33, thereby meeting the displacement requirements of the sealing strip 20 in height.

[0043] Please combine Figure 6 In one embodiment, the spring strip 30 is provided in two parts, each spring strip 30 including a mounting end 31 and a first fixing part 32 respectively disposed at both ends, and an elastic deformation part 33 disposed between the mounting end 31 and the first fixing part 32. By separating the spring strips 30, the length of the spring strips 30 can be reduced, the strength of the spring strips 30 can be guaranteed, and the processing of the spring strips 30 and the assembly of the spring strips 30 with the sealing seat 10 can be facilitated.

[0045] In one embodiment, the driving assembly 40 further comprises a touch rod 41, one end of the touch rod 41 is provided with external threads, the other end of the sliding block 42 away from the spring mounting hole is provided with first internal threads, the touch rod 41 and the sliding block 42 are detachably connected by the external threads and the first internal threads, the other end of the touch rod 41 extends out of the end of the sealing seat 10 and can extend out of the door leaf frame being pressed by the external structure.

[0046] By setting the touch rod 41 threadedly connected with the sliding block 42, the length of the exposed part of the touch rod 41 can be adjusted by adjusting the length of the connecting part between the touch rod 41 and the sliding block 42, so that the driving assembly 40 can be normally pressed by the external structure (such as the door frame), and the use requirement of different distances between the longitudinal edge of the door leaf and the door frame is met.

[0047] In one embodiment, the limiting assembly 50 comprises a limiting block 51 and a locking screw 52, the limiting block 51 is provided with a second spring mounting hole and a second internal thread at both ends respectively, the mounting end 31 of the spring strip 30 is inserted into the second spring mounting hole, and the locking screw 52 is connected with the second internal thread for fixing the limiting block 51 with the door leaf frame.
