[0030] See Figures 1 to 8 This utility model relates to a door leaf sealing device 100 and a door leaf using the door leaf sealing device 100. The door leaf is, for example, a sliding door, having a door leaf body and a slide rail 300 disposed at at least one end of the vertical ends of the door leaf body. The door leaf sealing device 100 is used to realize the windproof function of the door leaf, preventing outdoor wind from seeping into the room through the gap between the door leaf body and the slide rail 300, thereby improving the user experience. The door leaf body includes a leaf panel (not shown) and a horizontal frame 200.

[0031] The door sealing device 100 includes a baffle assembly 10, a spring strip 20, a limiting assembly 40, and a driving assembly 30.

[0032] The upper end of the baffle assembly 10 is provided with a spring storage groove 11, and its lower end extends in a direction away from the spring storage groove 11 to form a windproof baffle 12.

[0033] The spring bar 20 is long and made of a metal material that is elastic and can return to its original shape. It includes an installation end 21, a first fixing part 22 and an elastic deformation part 23 connected between the two. The first fixing part 22 is fixed to the baffle assembly 10. The elastic deformation part 23 is embedded in the spring storage groove 11 and can be deformed by force towards the bottom of the spring storage groove 11.

[0034] The limiting component 40 and the driving component 30 are respectively disposed at both ends of the baffle assembly 10 along its length and are both connected to the mounting end 21 of the spring strip 20. The limiting component 40 is used to fix to the transverse frame 200 to limit the transverse displacement of the spring strip 20. The driving component 30 is used to move towards the limiting component 40 and fix to the transverse frame 200 when the door leaf is installed on the slide rail 300, thereby compressing the spring strip 20 to deform and push the windproof baffle 12 out of the transverse frame and into the sealing groove 310 on the slide rail 300.

[0035] The working principle of the door sealing device 100 of this utility model is as follows: the drive component 30 installed in the horizontal frame moves towards the limiting component 40 and is fixed to the horizontal frame 200 of the door leaf. During the process of fixing with the horizontal frame, the spring strip 20 is squeezed. The spring strip 20 has a tendency to move towards the limiting component 40. Since the limiting component 40 is fixed to the horizontal frame, the horizontal movement of the spring strip 20 is restricted. The spring strip 20 can only undergo elastic deformation in the direction of the bottom of the spring storage groove 11 of the baffle component 10, thereby pushing the windproof baffle 12 to move away from the horizontal frame. The windproof baffle 12 gradually extends out from the horizontal frame and finally extends into the pre-set sealing groove 310 on the door leaf slide rail 300, preventing wind from seeping into the room from the gap between the door leaf body and the door leaf slide rail 300, thus achieving the windproof effect.

[0036] In one embodiment, the baffle assembly 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 spring receiving groove 11.

[0037] The portion of the spring strip 20 furthest from the mounting end 21 is bent into an arched structure to form the first fixing part 22. The arched structure passes through the clearance hole and is then fixed to the spring strip 20 and the baffle assembly 10 by a rod-like component. Optionally, the spring strip 20 and the baffle assembly 10 are riveted together or connected by a pin.

[0038] In one embodiment, the spring bar 20 is provided as a single unit, with mounting ends 21 respectively provided at both ends, and the first fixing part 22 is provided between the two mounting ends 21.

[0039] As can be seen from the above embodiments, the extension amount of the windproof baffle 12 is related to the deformation range of the elastic deformation portion 23. In one embodiment, two first fixing portions 22 are provided, and the two first fixing portions 22 are arranged at intervals. The elastic deformation portion 23 is formed between the first fixing portion 22 and the nearest mounting end 21. The lengths of the two elastic deformation portions 23 are equal or unequal. Thus, by providing two first fixing portions 22, the technician can adjust the spacing between the two first fixing portions 22 according to the required deformation range of the two elastic deformation portions 23, thereby meeting the displacement requirements of the windproof baffle 12 in height.

[0040] In one embodiment, the spring bar 20 is provided with two spring bars, each spring bar 20 including a mounting end 21 and a first fixing part 22 respectively disposed at both ends, and an elastic deformation part 23 disposed between the mounting end 21 and the first fixing part 22.

[0041] In one embodiment, the spring strip 20 is provided in two parts, each spring strip 20 including a mounting end 21 and a first fixing part 22 respectively disposed at both ends, and an elastic deformation part 23 disposed between the mounting end 21 and the first fixing part 22. By separating the spring strips 20, the length of the spring strips 20 can be reduced, the strength of the spring strips 20 can be guaranteed, and the processing of the spring strips 20 and the assembly of the spring strips 20 with the baffle assembly 10 can be facilitated.

[0042] In one embodiment, the drive assembly 30 includes a slider 31, one end of which facing the limiting assembly 40 is provided with a first spring mounting hole 311, the mounting end 21 of the spring strip 20 is inserted into the first spring mounting hole 311, and the slider 31 is configured to slide along the length direction of the baffle assembly 10.

[0043] In one embodiment, the drive assembly 30 further includes an adjusting screw 32, which is threadedly connected to the slider 31.

[0044] In one embodiment, the slider 31 includes a slider 31 body and a fixing screw 33 with internal threads placed inside the slider 31 body, wherein the adjusting screw 32 is threadedly connected to the internal threads of the fixing screw 33.

[0045] By setting the adjusting screw 32 to be threadedly connected to the slider 31, the deformation amplitude of the spring can be adjusted as needed, thereby adjusting the extension amount of the windproof baffle 12 to adapt to different usage needs of the door body and the door slide rail 300.

[0046] In one embodiment, the limiting component 40 includes a limiting block 41 and a locking screw 42. The limiting block 41 has a second spring mounting hole 411 and a second internal thread at both ends. The mounting end 21 of the spring strip 20 is inserted into the second spring mounting hole 411. The locking screw 42 is connected to the second internal thread to fix the limiting block 41 to the horizontal frame.

[0047] As a second aspect, the present invention also provides a door leaf, including a door leaf body and a slide rail 300 disposed at at least one vertical end of the door leaf body, wherein the aforementioned door leaf sealing device 100 is provided in the horizontal frame 200.

[0048] In one embodiment, the inner side of the horizontal frame 200 is provided with a first storage cavity and a second storage cavity in sequence along the direction away from the fan plate. The second storage cavity is connected to the first storage cavity and has an opening. The driving component 30 and the limiting component 40 are both housed in the first storage cavity. The baffle component 10 is disposed in the second storage cavity and the windproof baffle 12 can extend out from the opening.

[0049] Thus, the drive assembly 30 and the limiting assembly 40 are arranged in layers with the baffle assembly 10 in the horizontal frame 200, limiting the lateral movement of the drive assembly 30 in the horizontal frame 200, and the baffle assembly 10 moves in the height direction relative to the horizontal frame 200, so that when the drive assembly 30 is pressed (such as when the drive assembly 30 is fixed to the horizontal frame 200), the windproof baffle 12 extends out from the opening of the horizontal frame 200 and is inserted into the sealing groove 310 of the door slide rail 300.

[0050] It should be understood that the horizontal frame 200 includes an upper frame and / or a lower frame, and the door slide rail 300 includes an upper slide rail 300 and / or a lower slide rail 300. As needed, technicians may install door sealing devices 100 in the upper and lower frames to seal gaps in corresponding directions (door gaps above or below the door) to solve the problem of air leakage between the sliding door body and the door slide rail 300.

[0051] In addition, it is understandable that in order to enhance the windproof effect, a wool strip can be provided in the sealing groove 310, and the wool strip abuts against both sides of the windproof baffle 12 when the windproof baffle 12 is inserted into the sealing groove 310.

[0052] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model is not limited to the specific combination of the above-described technical features, but also includes other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features of the utility model in this utility model that have similar functions.

[0053] Although the subject matter has been described using language specific to structural features and / or methodological logic, it should be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or actions described above. Rather, the specific features and actions described above are merely illustrative examples of implementing the claims.
