However, this patent still has the following problems in actual use:
[0004] The bracket is fixed to the adjusting screw by two adjusting nuts to fix the suspended end of the coarse-pore aerator, preventing the suspended end from shaking with the water flow and enhancing the connection stability of the coarse-pore aerator. However, the device is installed on one side of the air pipe by threads. As the usage time increases, the threaded connection will loosen, thereby affecting the connection stability and airtightness of the device and reducing the aeration effect of the device.
[0005] A coarse-pore aerator is proposed to address the aforementioned problems. Utility Model Content
[0006] The purpose of this invention is to provide a coarse-pore aerator to solve the problem that, with prolonged use, the threaded connection may loosen, thus affecting the connection stability and airtightness of the device.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a coarse-pore aerator, comprising an air pipe and an aerator body, wherein a connecting pipe is fixedly connected to one side of the air pipe;
[0008] The aerator body is connected to a connector pipe on the side near the air pipe, and the connector pipe is engaged with the connector pipe.
[0009] Also includes:
[0010] A fixing sleeve is fixedly connected to the outside of the air pipe, and a pin is fixedly connected to the side of the fixing sleeve near the aerator body. A connecting sleeve is fixedly connected to the outside of the aerator body.
[0011] The connecting sleeve is fixedly connected to a sleeve on the side near the pin, and a connecting tube is connected to the side of the sleeve near the connecting sleeve. An airbag part is fixedly sleeved on the outside of the connecting tube, and the end of the connecting tube away from the sleeve is connected to the airbag part.
[0012] A plug rod is fixedly connected to the outer side of the middle part of the pin, and a connecting block is symmetrically fixedly connected to the outer side of the connecting sleeve. The pin and the connecting block are slidably installed. A positioning pin is slidably installed inside the connecting block. A compression spring is sleeved on the outer side of the positioning pin.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] The system is equipped with a pin, sleeve, connecting pipe, air bladder, insert rod, connecting block, and positioning pin. When installing the air pipe and aerator body, the operator inserts the insert pipe into the connecting pipe, pulls the positioning pins on both sides, and inserts the pin into the connecting block. The pin moves the insert rod, which then inserts into the sleeve, compressing the gas inside. The gas passes through the connecting pipe and fills the air bladder, causing it to expand and seal the connection between the connecting pipe and the insert pipe. This continues until the slot moves to the position of the positioning pin. The spring force then pushes the positioning pin into the slot, completing the splicing and fixing of the air pipe and aerator body. This solves the problem of threaded installations, which can loosen over time, affecting the connection stability and airtightness of the device.
[0021] The symmetrically arranged fixing sleeves and pins improve the stability of the air pipe and aerator body installation. The installation and positioning of the pins and connecting blocks strengthen the connection between the air pipe and the aerator body, reducing the possibility of damage to the end of the aerator body away from the air pipe. The symmetrically arranged positioning pins facilitate the tightening and limiting of the pins, enabling the air pipe and aerator body to be quickly spliced and fixed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1 - Figure 6 The present invention provides a technical solution: a coarse-pore aerator, comprising an air pipe 1 and an aerator body 2, wherein a connecting pipe 3 is fixedly connected to one side of the air pipe 1.
[0031] The aerator body 2 is connected to the insertion pipe 4 on the side near the air pipe 1, and the connecting pipe 3 is engaged with the insertion pipe 4.
[0032] A fixing sleeve 5 is fixedly connected to the outside of the air pipe 1. A pin 6 is fixedly connected to the side of the fixing sleeve 5 near the aerator body 2. The fixing sleeves 5 are symmetrically arranged. The number of pins 6 is the same as that of the fixing sleeves 5. A connecting sleeve 7 is fixedly connected to the outside of the aerator body 2.
[0033] The symmetrically arranged fixing sleeve 5 and pin 6 improve the stability of the installation of air pipe 1 and aerator body 2.
[0034] Among them, the connecting sleeve 7 is fixedly connected to the side of the pin 6 with a sleeve 8, and the sleeve 8 is connected to the side of the connecting sleeve 7 with a connecting tube 9. The sleeve 8 includes two symmetrically arranged sleeves. The connecting tube 9 is connected to the inside of the sleeve 8. The outer side of the insertion tube 4 is fitted with an airbag part 10. The end of the connecting tube 9 away from the sleeve 8 is connected to the airbag part 10.
[0035] A rod 11 is fixedly connected to the outer side of the middle part of the pin 6, and a connecting block 12 is symmetrically fixedly connected to the outer side of the connecting sleeve 7. The pin 6 and the connecting block 12 are slidably installed. A positioning pin 13 is slidably installed inside the connecting block 12. A compression spring 15 is sleeved on the outer side of the positioning pin 13. A slot 16 is opened on the outer side of the pin 6.
[0036] By installing and positioning the pin 6 and the connecting block 12, the connection strength between the air pipe 1 and the aerator body 2 is strengthened, reducing the possibility of damage to the end of the aerator body 2 away from the air pipe 1.
[0037] The insertion rod 11 is L-shaped and is slidably connected to the sleeve 8. The insertion rod 11 and the sleeve 8 are interlocked and matched. A sealing layer is provided at the connection between the inner wall of the sleeve 8 and the insertion rod 11. The insertion rod 11 is located on the side of the pin 6 near the aerator body 2.
[0038] The connecting block 12 has a slot inside, the pin 6 is slidably connected to the slot, the positioning pin 13 is slidably connected to the connecting block 12, and the end of the positioning pin 13 away from the connecting block 12 is fixedly connected to the fixing block 14. The compression spring 15 is located between the connecting block 12 and the fixing block 14. The symmetrically arranged positioning pins 13 facilitate the compression and limiting of the pin 6, so that the air pipe 1 and the aerator body 2 can be quickly spliced and fixed.
[0039] When installing the air pipe 1 and the aerator body 2, the operator inserts the insertion pipe 4 into the connecting pipe 3, pulls the positioning pins 13 on both sides, inserts the pin 6 into the connecting block 12, and the pin 6 drives the insertion rod 11 to move. The insertion rod 11 inserts into the sleeve 8 and squeezes the gas inside the sleeve 8. The gas is filled into the air bladder 10 through the connecting pipe 9, causing the air bladder 10 to expand and seal the connection between the connecting pipe 3 and the insertion pipe 4.
[0040] Until the slot 16 moves to the position of the positioning pin 13, the elastic force of the compression spring 15 drives the positioning pin 13 to insert into the slot 16, thereby completing the splicing and fixing of the air pipe 1 and the aerator body 2. This solves the problem that with the threaded installation method, as the usage time increases, the threaded connection will loosen, thus affecting the connection stability and airtightness of the device.
[0041] One end of the compression spring 15 is fixedly connected to the connecting block 12, and the other end of the compression spring 15 is fixedly connected to the fixing block 14.
[0042] The slot 16 is located on the side of the pin 6 near the positioning pin 13, and the positioning pin 13 is engaged with the slot 16.
[0043] Working principle:
[0044] Before using this type of coarse-pore aerator, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 6 As shown, when installing the air pipe 1 and the aerator body 2, the operator inserts the connector 4 into the connecting pipe 3, pulls the positioning pins 13 on both sides, inserts the pin 6 into the connecting block 12, and the pin 6 drives the rod 11 to move. The rod 11 inserts into the sleeve 8 and squeezes the gas inside the sleeve 8. The gas is filled into the air bladder 10 through the connecting pipe 9, causing the air bladder 10 to expand and seal the connection between the connecting pipe 3 and the connector 4 until the slot 16 moves to the position of the positioning pin 13. The elastic force of the compression spring 15 drives the positioning pin 13 to insert into the slot 16, thereby completing the splicing and fixing of the air pipe 1 and the aerator body 2.
