[0032] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figure 1 and Figure 2 shown, a belt clamping device for a linkage door provided by an embodiment of the present utility model includes a fixed part 1, a base 2, and a roller 3. Among them, the fixed part 1 is fixed to one side of the window sash 10 (as Figure 3 shown), and has a slide rail 101 arranged in the vertical direction. The first end of the base 2 (i.e., the right end in Figure 1 ) is formed with a clamping part 21 for clamping a belt (not shown in the figure) installed on the window sash. The second end of the base 2 (i.e., the left end in Figure 1 ) is provided with a sliding fit part 22 arranged in the vertical direction, and the sliding fit part 22 is slidably fitted with the slide rail 101, so that the base 2 can reciprocally move in the vertical direction relative to the fixed part 1, thereby driving the clamping part 21 to adjust the clamping height of the belt. The roller 3 is rotatably arranged on the clamping part 21 around the vertical direction for rolling cooperation with another window sash 10.

[0034] As Figure 2As shown in the figure, in this embodiment, the fixing member 1 is L-shaped and consists of a cross bar 11 and a vertical bar 12. Among them, a wedging groove 13 is formed on the upper surface of the cross bar 11, and a wedging bolt 14 is installed in the wedging groove 13 for fixing the fixing member 1 to the window sash 10. Preferably, the wedging groove 13 is an inclined groove, so that the wedging bolt 14 can connect the fixing member 1 and the window sash 10 at an inclined upward angle, which is beneficial to improving the connection strength. One fixing plate 15 is provided on each side of the vertical bar 12. The two fixing plates 15 are parallel to each other and a dovetail protrusion is provided on the inner surface along the vertical direction. The two dovetail protrusions are arranged oppositely to jointly form a slide rail 101.

[0035] In the above embodiment, preferably, at least one threaded hole 121 is formed on the outer side of the vertical bar 12, and a fastening bolt 16 is threadedly connected in the threaded hole 121. Thus, by screwing the fastening bolt 16 into the threaded hole 121, the inner end surface of the fastening bolt 16 abuts against the second end of the base 2 (drilling holes on the upper surface of the base 2 can be avoided), thereby restricting the relative position between the fixing member 1 and the base 2. Preferably, the number of the threaded holes 121 is multiple (two in this embodiment), and the multiple threaded holes 121 are arranged at intervals in the vertical direction, so as to further ensure the positioning effect on the base 2. It can be understood that the positioning and installation of the base 2 can be very conveniently carried out by using this structural form. Moreover, in cooperation with the sliding connection between the sliding fit portion 22 and the slide rail 101, the sliding guide for the height adjustment of the base 2 can also be carried out to further improve the convenience of the height adjustment of the base 2.

[0036] As Figure 2 shown in the figure, in this embodiment, the base 2 is U-shaped. The first end (i.e., the right end) of the base 2 is a clamping portion 21, and the second end (i.e., the left end) is a sliding fit portion 22. Among them, a plurality of belt holes 211 are formed on the clamping portion 21, and the plurality of belt holes 211 are distributed at intervals in the horizontal direction. A belt is passed through any one of the belt holes 211 and connected to the clamping portion 21. Thus, the tightness of the belt can be adjusted through the belt holes 211 at different positions. The sliding fit portion 22 is a dovetail groove formed on both sides of a cuboid column, and is symmetrically arranged on both sides of the second end of the base 1, so that the base 1 can be installed regardless of left or right, adapting to different installation directions and improving the convenience of the installation of the base 1. In addition, the dovetail groove matches the dovetail protrusion on the slide rail 101, so as to realize the horizontal limit between the fixing member 1 and the base 2 to prevent the slide rail 101 from disengaging from the sliding fit portion 22.

[0037] In the above embodiments, preferably, a rotating column 212 is provided at the top of the clamping portion 21, and the axial direction of the rotating column 212 is parallel to the vertical direction. Correspondingly, the roller 3 is rotatably sleeved on the rotating column 212, which facilitates the installation or disassembly of the roller 3. It can be understood that by rolling the roller 2 provided on the rotating column 212 with the window sash 10, it is possible to avoid setting a guide rail on the ground, which is beneficial to improving the aesthetics of the door and window structure.

[0038] In the above embodiments, preferably, the fixing member 1 is integrally formed, and the base 2 is integrally formed to reduce the assembly process and improve production efficiency.

[0039] As Figure 4 shown, the embodiment of the present invention further provides a linkage door structure, which includes the above belt clamping device, and also includes structural members such as window sashes and hanging rails, which will not be specifically described here.

[0040] In summary, a belt clamping device and a linkage door structure for a linkage door provided by the embodiment of the present invention have the following beneficial effects:

[0041] (1) Through the sliding fit between the sliding fit portion 22 and the sliding rail 101, the base 2 can reciprocally move in the vertical direction relative to the fixing member 1, thereby driving the clamping portion 21 to adjust the clamping height of the belt.

[0042] (2) By providing at least one threaded hole 121 on the outer side of the vertical rod 12, and a fastening bolt 16 is threadedly connected in the threaded hole 121, the positioning and installation of the base 2 are realized by the end face of the fastening bolt 16 abutting against the surface of the base 2. Thus, drilling holes in the base 2 is avoided, and the convenience of positioning and installing the base 2 is improved.

[0043] (3) The sliding fit portion 22 is a dovetail groove opened on both sides of the rectangular column, and is symmetrically arranged on both sides of the second end of the base 1, so that the base 1 can be installed regardless of left or right, adapting to different installation directions, and improving the convenience of installing the base 1.

[0044] (4) By rolling the roller 2 provided on the rotating column 212 with the window sash 10, it is possible to avoid setting a guide rail on the ground, which is beneficial to improving the aesthetics of the door and window structure.
