[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figures 1 to 4 As shown;

[0027] A building expansion joint structure comprises a building body 1 and a water stop strip 11 arranged inside the building body 1;

[0028] In this embodiment: after checking the public (announcement) number: CN213115043U discloses a building expansion joint structure, but this expansion joint structure is not equipped with a dust blocking device, which will cause dust to accumulate inside. When the building expands and contracts due to thermal expansion and contraction, it will affect the operation of the expansion joint structure and reduce the life of the expansion joint structure. In order to solve this technical problem, a dustproof component 2 and an auxiliary component 3 are added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 4 As shown;

[0031] Combining the above:

[0032] In order to achieve dust prevention of the expansion joint, the building expansion joint structure further includes a dust prevention component 2 arranged inside the building body 1;

[0033] The dustproof component 2 includes two positioning grooves 21 symmetrically opened inside the building body 1, a positioning block 22 is inserted inside each positioning groove 21, the positioning block 22 and the building body 1 are slidably connected, and the opposite sides of the two positioning blocks 22 are fixedly connected with plug blocks 23, and two limiting grooves 212 are symmetrically opened inside the building body 1, and the plug blocks 23 are inserted inside the limiting grooves 212. The upper surface of each positioning block 22 is fixedly connected with a positioning plate 24, and the upper surface of each positioning plate 24 is fixedly connected with a slider 27. The upper surfaces of the two positioning plates 24 are provided with a cover plate 25, and the bottom surface of the cover plate 25 is provided with a slide groove 26, and the slider 27 is inserted inside the slide groove 26, and the slide groove 26 and the cover plate 25 are slidably connected.

[0034] In this embodiment: when the expansion joint needs to be waterproof and dustproof, the water stop strip 11 is placed inside the expansion joint and the two ends are inserted into the two positioning grooves 21, and then the two positioning plates 24 are squeezed in the direction of the cover plate 25, and the slider 27 connected to the positioning plate 24 will slide inside the slide groove 26, and the positioning block 22 connected to the positioning plate 24 will move closer to each other until the two plug-in blocks 23 can be inserted into the positioning groove 21, so that the plug-in blocks 23 slide downward inside the positioning groove 21 until they slide to a suitable position, and the two positioning plates 24 are loosened. The torsion spring 211 will insert the two plug-in blocks 23 into the limiting groove 212 due to the elastic potential energy, thereby achieving the limitation of the positioning block 22 and the installation of the cover plate 25.

[0035] Going further:

[0036] In an optional embodiment, the upper surface of the cover plate 25 is a serrated structure.

[0037] In this embodiment, the upper surface of the cover plate 25 is set to be serrated. First, it is more eye-catching and prevents force from being applied to it. Second, the serrated structure has better support than the flat structure.

[0038] Going further:

[0039] In an optional embodiment, two adjacent sides of the two positioning blocks 22 are symmetrically fixedly connected to two support rods 28, and one end of each support rod 28 away from the positioning block 22 is rotatably connected to a connecting rod 29. The two connecting rods 29 are rotatably connected to each other through a rotating shaft 210 at one end away from the support rod 28. A torsion spring 211 is sleeved on the surface of the rotating shaft 210, and the two ends of the torsion spring 211 are respectively fixedly connected to the two connecting rods 29.

[0040] In this embodiment, the two building bodies 1 will move toward the middle, the two positioning blocks 22 will be squeezed, the two support rods 28 will move toward the middle, the connecting rod 29 will rotate at the end of the support rod 28 away from the positioning block 22, the two connecting rods 29 will rotate with each other through the rotating shaft 210, and the torsion spring 211 will be compressed. When the two building bodies 1 expand to both sides, the torsion spring 211 will rotate the two connecting rods 29 in opposite directions with the rotating shaft 210 as the axis due to elastic potential energy, so that the two positioning blocks 22 can move close to the building body 1.

[0041] Going further:

[0042] In an optional embodiment, it further includes an auxiliary component 3 disposed on the surface of the cover plate 25;

[0043] The auxiliary component 3 includes two scraping blocks 31 symmetrically fixedly connected to the two ends of the cover plate 25 , and the two scraping blocks 31 are both attached to the surface of the positioning plate 24 .

[0044] In this embodiment, since the contraction and expansion of the building body 1 is a relatively slow movement, the two scraping blocks 31 fixed on both sides of the cover plate 25 can scrape off the dust on the surface of the positioning plate 24 during contraction to prevent it from entering the interior of the expansion joint.

[0045] The working principle and use process of the utility model are as follows: when the expansion joint needs to be waterproof and dustproof, the water stop strip 11 is placed inside the expansion joint and the two ends are inserted into the two positioning grooves 21, and then the two positioning plates 24 are squeezed in the direction of the cover plate 25, and the slider 27 connected to the positioning plate 24 will slide inside the slide groove 26, and the positioning block 22 connected to the positioning plate 24 will move closer to each other, and the support rod 28 connected to the positioning block 22 makes the two connecting rods 29 rotate at one end of the support rod 28, and the two connecting rods 29 rotate with each other through the rotating shaft 210, and the torsion spring 211 will be squeezed until the two plug blocks 23 can be inserted into the positioning groove 21, so that the plug blocks 23 slide downward inside the positioning groove 21 until they slide to a suitable position, and the two positioning plates 24 are released. The torsion spring 211 will insert the two plug blocks 23 into the limit groove due to elastic potential energy. The interior of 212 realizes the limitation of the positioning block 22, and the installation of the cover plate 25. When the expansion joint shrinks, the two building bodies 1 will move closer to the middle, the two positioning blocks 22 will be squeezed, the two support rods 28 will move closer to the middle, and the connecting rod 29 will rotate at the end of the support rod 28 away from the positioning block 22. The two connecting rods 29 will rotate with each other through the rotating shaft 210, and the torsion spring 211 will be compressed. When the two building bodies 1 expand to both sides, the torsion spring 211 will rotate the two connecting rods 29 in opposite directions with the rotating shaft 210 as the axis due to elastic potential energy, so that the two positioning blocks 22 can move closely against the building body 1. Because the contraction and expansion of the building body 1 is a slower movement, the two scraping blocks 31 fixed on both sides of the cover plate 25 can scrape off the dust on the surface of the positioning plate 24 during contraction to prevent it from entering the interior of the expansion joint.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
