Description

Technical Field

[0001] The utility model relates to the technical field of anti-cracking net structures, in particular to a wall anti-cracking net structure. Background Art

[0002] Wall anti-crack mesh is a material used to prevent wall cracking. It is usually installed on the surface or inside of the wall to enhance the structural strength and stability of the wall.

[0003] The wall anti-cracking net can effectively enhance the overall strength of the wall and improve the wall's load-bearing capacity and stability through its high-strength material and mesh structure. At the same time, when the wall is affected by factors such as temperature changes, humidity changes, and foundation settlement, the wall anti-cracking net can buffer and disperse stress to prevent cracks in the wall.

[0004] However, when such wall anti-cracking nets in the prior art are used, such as the wall anti-cracking net structure of the Chinese patent application No. 202220403325.4, the anti-cracking net can be installed efficiently and conveniently by utilizing the mutual cooperation of the mounting plate, guide groove, guide shaft, cavity, connecting shaft, telescopic spring, connecting block and hinged rod of the mounting mechanism, so that the anti-cracking net is more convenient to use to prevent the entire anti-cracking net from falling off after the putty is applied. However, after the installation of the cavity 11; 12, connecting shaft; 14, connecting block; 15, hinged rod, there are large gaps between the parts, which are easy to shake, resulting in poor installation stability of the entire anti-cracking net. Therefore, a wall anti-cracking net structure needs to be improved to address this problem. Utility Model Content

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wall anti-cracking net structure, comprising a wall body, an anti-cracking net body is arranged on the outside of the wall body, a fixing mechanism for fixing the anti-cracking net is arranged between the wall body and the anti-cracking net body, the fixing mechanism comprising a fixing hole, a fixing ring, a filling column, and an expansion rod, a plurality of fixing holes are evenly opened on the outer surface of the wall body, a plurality of fixing rings are evenly fixedly arranged inside the anti-cracking net body, a filling column is fixedly arranged on one side of the surface of the fixing ring, an expansion rod is arranged on the side of the fixing ring away from the filling column, and an anti-loosening mechanism is arranged between the expansion rod and the fixing ring.

[0007] Preferably, the anti-loosening mechanism includes a limiting groove, a groove, and a limiting plate. The inner side wall of the fixing ring is evenly provided with a number of limiting grooves, the outer surface of the expansion rod is evenly provided with a number of grooves, and a limiting plate is fixed inside the groove. The anti-loosening mechanism can effectively prevent the expansion rod from loosening and falling off from the inside of the filling column when the expansion rod is inserted into the filling column, thereby ensuring the stability of the filling column being interference-fixed inside the fixing hole.

[0008] Preferably, one end of the expansion rod is fixedly provided with a chamfer, and the chamfer can facilitate the expansion rod to be inserted into the filling column.

[0009] Preferably, the interior of the filling column is hollow, and the expansion rod can be easily inserted through the hollow filling column, thereby squeezing the filling column, so that the filling column can be expanded, and the filling column can be tightly fixed in the fixing hole with interference fit.

[0010] Preferably, the limiting piece is made of elastic metal material. The limiting piece made of elastic metal material can have sufficient structural strength and elasticity. When the expansion rod enters, it can be squeezed and automatically deformed and accommodated in the groove. After the expansion rod is fully inserted, it bounces up under the action of its own elasticity and is stuck in the limiting groove, thereby effectively preventing the expansion rod from falling off from the filling column.

[0011] Preferably, the outer surface of the filling column is provided with notches all around, which facilitate the filling column to expand to all sides after the expansion rod is inserted, so that the expanded filling column can be firmly fixed in the fixing hole by interference fit.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model inserts the filling column of the anti-crack net body into the fixing hole first, so that the anti-crack net body can be preliminarily fixed, and then the expansion rod is inserted into the filling column in turn, so that the expansion rod can be used to squeeze the filling column, so that the filling column can be expanded, so that the filling column can be tightly fixed in the fixing hole with interference fit; after the anti-crack net is hung, it is stable and not easy to shake, and the fixing effect is good and not easy to fall off, thereby effectively ensuring the quality of subsequent wall painting.

[0014] 2. When the utility model is used, when the expansion rod is inserted into the filling column, the limiting piece is inserted into the limiting groove, which can effectively prevent the expansion rod from loosening and falling off from the filling column, thereby ensuring the stability of the filling column being fixed in the fixing hole by interference fit.

The inner side wall of the fixing ring 4 is evenly provided with a plurality of limiting grooves 7, and the outer surface of the expansion rod 6 is evenly provided with a plurality of grooves 8. The limiting piece 9 is fixedly arranged inside the groove 8. The anti-loosening mechanism can effectively prevent the expansion rod 6 from loosening and falling off from the filling column 5 when the expansion rod 6 is inserted into the filling column 5, thereby ensuring the stability of the filling column 5 interference-fixed inside the fixing hole 3;

[0023] One end of the expansion rod 6 is fixedly provided with a chamfer 10, which makes it easy to insert the expansion rod 6 into the filling column 5;

[0024] The interior of the filling column 5 is hollow, and the expansion rod 6 can be easily inserted through the hollow filling column 5, thereby squeezing the filling column 5, so that the filling column 5 can be expanded, so that the filling column 5 can be tightly fixed in the fixing hole 3 with interference fit;

[0025] The limiting piece 9 is made of an elastic metal material. The limiting piece 9 made of the elastic metal material has sufficient structural strength and elasticity. When the expansion rod 6 enters, it is squeezed and automatically deformed and accommodated in the groove 8. After the expansion rod 6 is fully inserted, it bounces up under the action of its own elasticity and snaps into the limiting groove 7, thereby effectively preventing the expansion rod 6 from falling off from the filling column 5.
