[0002] Air foaming pouring is generally done by injecting a foaming agent into the mixture to produce a large number of bubbles, making the mixture light and having thermal insulation properties. Air foaming pouring machines and air injection devices are used. In the construction industry, they are often used to make insulation boards, insulation mortar and other materials to improve the thermal insulation performance and lightweight of building structures.

[0003] In the prior art, most air injection devices used for air foaming pouring machines are generally provided with filter elements and filter screens, through which impurities in the air can be filtered. However, in the prior art, most filter screens are connected to the air injection devices by bolts. When the air injection device is working, it will vibrate continuously, causing the bolts to loosen, which will cause the filter screen to loosen, resulting in a gap between the filter screen and the device housing. Large impurities will directly contact the filter element through the gap, affecting the service life of the filter element. Therefore, it is necessary to design an air foaming air injection device with a multi-stage filtering mechanism that can avoid bolt loosening to solve the above problems. Utility Model Content

This effectively solves the problem that most of the existing technologies proposed in the background technology are connected to the air injection device by bolts, and the air injection device will vibrate continuously when working, causing the bolts to loosen, which in turn causes the filter to loosen, resulting in a gap between the filter and the device housing. Larger impurities will directly contact the filter element through the gap, affecting the service life of the filter element. This achieves the technical effect of avoiding bolt loosening, ensuring the stability of the filter, avoiding direct contact between larger impurities and the filter element, and ensuring the service life of the filter element.

[0023] In this embodiment, a fixed plate 10 is slidably connected to one side of the first square plate 8, and the fixed plate 10 is fixedly connected to the first mounting plate 1. The fixed plate 10 is fixedly connected to a second square plate 11 on one side close to the third rectangular plate 12, and the second square plate 11 is fixedly connected to the third rectangular plate 12.

[0024] In this embodiment, the third square plate 12 is fixedly connected to two connecting plates 14 on the side away from the first square plate 8. The connecting plates 14 pass through the limit block 6. Both ends of the limit block 6 are provided with slots 13 that are compatible with the connecting plates 14. The connecting plates 14 are arranged in the slots 13, and the connecting plates 14 are slidably connected to the limit block 6.

[0025] In this embodiment, a shifting plate 15 is fixedly connected to the limiting block 6 at one side close to the first square plate 8 , and the shifting plate 15 is sleeved on the connecting rod 7 .

[0026] In this embodiment, mounting holes 16 in a square layout are provided on the first mounting plate 1 and the second mounting plate 2, and bolts 5 are arranged in the mounting holes 16. The first mounting plate 1 is fixedly connected to four threaded sleeves 17 in a square layout on the side away from the second mounting plate 2, and the threaded sleeves 17 are adapted to the bolts 5. The second mounting plate 2 is fixedly connected to a rubber pad 21 on the side away from the first mounting plate 1, and the rubber pad 21 is arranged at the position of the mounting hole 16.

[0027] In this embodiment, the first mounting plate 1 is fixedly connected to a pipe 18 on a side away from the second mounting plate 2, a filter element 19 is fixedly connected to the inner wall of the pipe 18, an air injection device body 20 is provided on the side of the pipe 18 away from the first mounting plate 1, and the pipe 18 is fixedly connected to the air inlet of the air injection device body 20.

[0028] Working principle: When installing the filter 4, the second mounting plate 2 can be placed close to the first mounting plate 1, so that the filter 4 contacts the inner wall of the first mounting plate 1, and the mounting holes 16 of the first mounting plate 1 and the second mounting plate 2 are aligned. Then the bolt 5 can be screwed to make the bolt 5 rotate into the threaded sleeve 17. When screwing the bolt 5, first turn the toggle plate 15, and the toggle plate 15 will drive the limit block 6 to move, so that the limit block 6 moves toward the direction of the first square plate 8, and the limit block 6 will drive the connecting rod 7 to move, and the connecting rod 7 will drive the first square plate 8 to move. The movement of the first square plate 8 will pull the tension spring 9 to stretch the tension spring 9. When the limit block 6 moves, the connecting plate 14 will move in the slot 13. Due to the restriction of the connecting plate 14, the limit block 6 will not be offset when moving. After the bolt 5 is completely screwed into the threaded sleeve 17, the toggle plate 15 is loosened, and the tension spring 9 will contract, so that the limit block 6 can be moved in the direction of the bolt 5 until it contacts the bolt 5. After the bolt 5 is completely screwed into the threaded sleeve 17, the toggle plate 15 is loosened, and the limit block 6 can engage with the bolt 5 to limit the bolt 5. The vibration generated when the air injection device body 20 is working will not loosen the bolt 5, so the stability of the filter screen 4 can be guaranteed, and the filter screen 4 can be prevented from loosening and falling off. The dust and impurities in the air are primarily filtered through the filter screen 4, thereby reducing the burden on the filter element 19.
