[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] See also Figures 1 to 3 In the embodiment of the utility model, a grid seal that is easy to disassemble and assemble includes a grid seal 1 composed of a convex outer frame 101 and a shutter 102. The shutter 102 is installed on the inner side of the convex outer frame 101. One end of the convex outer frame 101 is provided with a convex mounting hole 103 that penetrates to the other end of the convex outer frame 101.

[0026] The inner side of the convex mounting hole 103 is provided with a quick-install component 2 extending to the rear end of the convex outer frame 101, and the quick-install component 2 is used to realize the convenient disassembly and assembly operation of the convex outer frame 101 and the inner side of the ventilation window 3;

[0027] The quick-install assembly 2 includes a fan-shaped fixing block 201, a bolt 203, and a limiting convex plate 204;

[0028] The fan-shaped fixing block 201 is fixed to the rear end of the convex outer frame 101, and the center line of the fan-shaped fixing block 201 coincides with the center line of the convex mounting hole 103;

[0029] The bolt 203 is installed inside the convex mounting hole 103 and extends to the inside of the fan-shaped fixing block 201. The limiting convex disc 204 is threadedly connected to the outside of the bolt 203, and the outer wall of the annular part of the limiting convex disc 204 is attached to the inner wall of the fan-shaped fixing block 201.

[0030] When the raised portion of the limiting convex disc 204 faces the inner side of the convex outer frame 101, it does not affect the insertion of the convex outer frame 101 into the inner side of the ventilation window 3. When the convex portion of the limiting convex disc 204 rotates toward the outer side of the convex outer frame 101, the convex outer frame 101 and the ventilation window 3 are connected and fixed by the convex portion of the limiting convex disc 204 and the edge of the ventilation window 3.

[0031] There are four groups of convex mounting holes 103 and quick-install components 2, which are respectively distributed on the four sides of the convex outer frame 101. The spiral directions of the outer wall threads of the two bolts 203 in the two symmetrically distributed groups of quick-install components 2 are in opposite states, and the inner side of the limiting convex plate 204 is formed with a thread groove that matches the outer wall thread of the bolt 203.

[0032] The outer diameter of the annular portion of the limiting convex disc 204 matches the inner diameter of the sector-shaped fixing block 201, and the rotation angle of the limiting convex disc 204 is 180 degrees;

[0033] The convex outer frame 101, the convex mounting hole 103, the fan-shaped fixing block 201, and the limiting spring piece 202 are integrally formed by an injection molding process.

[0034] In this embodiment, when installing the grille seal 1, the operation steps are as follows:

[0035] First, use a screwdriver to tighten the bolt 203, so that the bolt 203 first drives the limiting convex plate 204 to rotate, so that the convex part of the limiting convex plate 204 rotates toward the inner side of the convex outer frame 101, and then, continue to tighten the bolt 203. At this time, the limiting convex plate 204 is limited by the fan-shaped fixing block 201 and cannot continue to rotate. Then, the limiting convex plate 204 is driven by the outer wall thread of the bolt 203 to move horizontally, and the limiting convex plate 204 will move away from the convex outer frame 101. When the distance between the limiting convex plate 204 and the diameter of the large-size part of the front end of the convex outer frame 101 is greater than the wall thickness of the ventilation window 3, the bolt 203 can be stopped from being screwed;

[0036] After that, the small-sized part of the convex outer frame 101 can be aligned with the inner side of the ventilation window 3 and inserted (it should be noted that the outer wall size of the small-sized part of the convex outer frame 101 matches the inner size of the ventilation window 3). Finally, the small-sized part of the convex outer frame 101 is completely inserted into the ventilation window 3, and the large-sized part of the convex outer frame 101 is attached to the front outer surface of the ventilation window 3. At this time, the limiting convex plate 204 completely passes through the ventilation window 3 to the rear end of the ventilation window 3.

[0037] Then, the bolt 203 is screwed in the opposite direction by a screwdriver. At this time, the bolt 203 first drives the limiting convex plate 204 to rotate so that its raised portion faces the outside of the convex outer frame 101. Then, the bolt 203 is further screwed. At this time, the limiting convex plate 204 moves horizontally close to the convex outer frame 101. Finally, the raised portion of the limiting convex plate 204 is attached to the rear end surface of the ventilation window 3, thereby realizing the installation and fixation of the convex outer frame 101 and the ventilation window 3.

[0038] The grille seal 1 can be conveniently disassembled and assembled by cooperating with the above-mentioned multiple parts. During the installation process, there is no need to drill holes on the wall, and the grille seal 1 can be adapted to installation operations on walls of different thicknesses. The grille seal 1 has a wider application range.

[0039] Please refer to Figures 2-3 , the quick-install assembly 2 also includes a limiting spring piece 202;

[0040] The limiting spring piece 202 is fixed to the side of the fan-shaped fixing block 201 facing the outside of the convex outer frame 101, and the end of the limiting spring piece 202 protrudes from the outside of the convex outer frame 101;

[0041] There are multiple limiting spring pieces 202 arranged on a single fan-shaped fixing block 201. When the convex outer frame 101 is inserted into the inner side of the ventilation window 3, the limiting spring pieces 202 are deformed by force. When the limiting spring pieces 202 pass through the ventilation window 3, they are reset and fit against the edge of the ventilation window 3 to achieve pre-fixation of the convex outer frame 101.

[0042] In this embodiment: when the convex outer frame 101 is installed inside the ventilation window 3, the limiting spring piece 202 is deformed by the contact force with the ventilation window 3. When the limiting spring piece 202 completely passes through the ventilation window 3, the limiting spring piece 202 is reset by its own elastic force. Finally, one of the limiting spring pieces 202 is in contact with the rear end surface of the ventilation window 3. In this way, the initial limiting of the convex outer frame 101 can be achieved. At this time, the support for the convex outer frame 101 can be released, and then the operator's hands can be released to facilitate the tightening operation of the bolt 203.

[0043] Please refer to Figure 1 The inner diameter of the large-size part of the convex mounting hole 103 matches the outer wall diameter of the top cap part of the bolt 203, and the depth of the large-size part of the convex mounting hole 103 is greater than the thickness of the top cap part of the bolt 203.

[0044] In this embodiment: through this structure, the bolt 203 can be completely received in the convex mounting hole 103, and a sealing plug can be provided to seal the opening of the convex mounting hole 103. After the installation is completed, the sealing plug is inserted into the convex mounting hole 103 to achieve the effect of hiding the ugliness;

[0045] It should also be noted that there is a certain friction between the top cap of the bolt 203 and the inner wall of the large-sized part of the convex mounting hole 103, which is used to limit the bolt 203 in the horizontal direction, so that the position of the limiting convex disc 204 remains fixed during the installation process.

[0046] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
