Technical Field

[0001] This utility model relates to the field of AOD furnace air gun technology, and in particular to a quick connector for an AOD furnace air gun. Background Technology

[0002] AOD furnace blast guns are used to deliver various process gases, such as oxygen, nitrogen, and argon, into the furnace to achieve the refining process of molten steel, including key operations such as decarburization, desulfurization, deoxidation, and adjustment of molten steel temperature and composition. They play a vital role in the iron and steel smelting process.

[0003] In existing technologies, AOD furnace air guns and metal hoses are generally connected by welding or a large number of bolts. When the air gun needs to be replaced, the bolted connection is difficult to disassemble. If the air gun and metal hose are connected by welding, they must be separated by cutting or other means. This not only damages the metal hose, making it unusable and increasing material costs, but also the cutting and re-welding process is very time-consuming, greatly extending the air gun replacement time and causing the AOD furnace to be shut down for a long time, which seriously affects production efficiency. Improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the conventional and complex connection method between the AOD furnace air gun and the metal hose in the existing technology, and the low efficiency of air gun replacement, and to propose a quick connector for the AOD furnace air gun.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick connector for an AOD furnace air gun, comprising a first connector and a second connector, wherein the fixed end of the first connector is fixedly connected to the air gun, the fixed end of the second connector is fixedly connected to a metal flexible hose, a threaded tube A is fixedly installed on the side of the first connector, a threaded tube B is fixedly installed on the side of the second connector, a connecting tube is fixedly installed on the side of the second connector, an installation groove is provided inside the first connector, a tension spring is fixedly connected to the side of the installation groove, a limit block is fixedly connected to one end of the tension spring, a limit groove is provided on the surface of the connecting tube, a connecting plate is fixedly installed on the surface of the limit block, a sliding rod is fixedly installed inside the first connector, and a connecting groove is provided inside the first connector.

[0006] Preferably, the fixed end of the first connector is fixedly connected to the air gun via a threaded tube A, and the fixed end of the second connector is fixedly connected to the metal hose via a threaded tube B.

[0007] Preferably, the connecting pipe and the connecting groove are slidably connected, and the limiting block and the limiting groove are slidably connected.

[0008] Preferably, the connecting plate and the slide rod are slidably connected.

[0009] Preferably, a limiting sleeve is slidably connected to the surface of the connecting pipe, a slot is provided on the side of the limiting sleeve, and a locking block is fixedly installed on the side of the connecting plate.

[0010] Preferably, the connecting plate and the limiting sleeve are slidably connected, and the card block and the card slot are slidably connected.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, through the design of tension spring, limiting block, limiting groove, connecting plate and sliding rod, when connecting the first connector and the second connector, the connecting tube is inserted into the connecting groove, and the limiting block is locked into the limiting groove under the action of tension spring, thereby realizing the quick connection and disassembly of the first connector and the second connector, making the connection process of the air gun and the metal hose more convenient, without the need to cut the metal hose directly, and the metal hose and the second connector can be reused, thereby greatly shortening the connection time of the air gun and the metal hose, thereby improving the production efficiency of the AOD furnace.

[0013] 2. In this utility model, the reliability and stability of the connector connection are further enhanced by the sliding connection between the limiting sleeve and the connecting pipe and the cooperation between the locking block and the slot.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a quick connector for an AOD furnace air gun, including a first connector 1 and a second connector 2. The fixed end of the first connector 1 is fixedly connected to the air gun, and the fixed end of the second connector 2 is fixedly connected to a metal flexible hose. A threaded tube A3 is fixedly installed on the side of the first connector 1, a threaded tube B4 is fixedly installed on the side of the second connector 2, and a connecting tube 5 is fixedly installed on the side of the second connector 2. An installation groove 6 is provided inside the first connector 1, and a tension spring 7 is fixedly connected to the side of the installation groove 6. One end of the tension spring 7 is fixedly connected to a limiting block 8. A limiting groove 9 is provided on the surface of the connecting tube 5, and a connecting plate 10 is fixedly installed on the surface of the limiting block 8. A sliding rod 11 is fixedly installed inside the first connector 1, and a connecting groove 12 is provided inside the first connector 1. The fixed end of the first connector 1 is fixedly connected to the air gun through the threaded tube A3, and the fixed end of the second connector 2 is fixedly connected to the metal flexible hose through the threaded tube B4. The connecting tube 5 is slidably connected to the connecting groove 12, the limiting block 8 is slidably connected to the limiting groove 9, and the connecting plate 10 is slidably connected to the sliding rod 11.

[0022] In this embodiment, through the design of tension spring 7, limiting block 8, limiting groove 9, connecting plate 10 and sliding rod 11, when connecting the first connector 1 and the second connector 2, the connecting pipe 5 is inserted into the connecting groove 12, and the limiting block 8 is locked into the limiting groove 9 under the action of tension spring 7, thereby realizing the quick connection and disassembly of the first connector 1 and the second connector 2, making the connection process of the air gun and the metal hose more convenient, without the need to cut the metal hose directly, and the metal hose and the second connector 2 can be reused, which can greatly shorten the connection time of the air gun and the metal hose, thereby improving the production efficiency of the AOD furnace.

[0023] Example 2: As Figures 1-4 As shown, a limiting sleeve 13 is slidably connected to the surface of the connecting pipe 5. A slot 14 is provided on the side of the limiting sleeve 13. A locking block 15 is fixedly installed on the side of the connecting plate 10. The connecting plate 10 and the limiting sleeve 13 are slidably connected, and the locking block 15 and the slot 14 are slidably connected.

[0024] In this embodiment, the sliding connection between the limiting sleeve 13 and the connecting pipe 5, and the cooperation between the locking block 15 and the slot 14, further enhance the reliability and stability of the connector connection. After the connector is connected, the limiting sleeve 13 is slid to a suitable position so that the locking block 15 is engaged in the slot 14. This effectively prevents the limiting block 8 from accidentally coming out of the limiting groove 9 due to external factors such as vibration, thus ensuring the stability and safety of the air gun during operation.

[0025] The working principle of this embodiment is as follows: Before connecting the air gun and the metal hose, ensure that the first connector 1 is securely connected to the air gun via the threaded tube A3, and the second connector 2 is connected to the metal hose via the threaded tube B4. Then, insert the connecting tube 5 of the second connector 2 into the connecting groove 12 of the first connector 1. During insertion, the surface of the connecting tube 5 pushes the limiting block 8 in the mounting groove 6 of the first connector 1, causing the limiting block 8 to compress the tension spring 7 and slide along the connecting plate 10 on the slide rod 11. When the connecting tube 5 is fully inserted into the connecting groove 12, the limiting block 8, under the elastic force of the tension spring 7, is engaged in the limiting groove 9 on the surface of the connecting tube 5. At this point, the initial connection of the first connector 1 and the second connector 2 is completed. Next, slide the limiting sleeve 13 on the connecting tube 5 along the connecting tube 5, aligning its side groove 14 with the locking block 15 on the connecting plate 10. As the limiting sleeve 13 continues to slide... The locking block 15 will engage with the locking groove 14, further fixing the position of the limiting block 8, thereby enhancing the reliability and stability of the connector connection. This prevents the limiting block 8 from dislodging from the limiting groove 9 due to vibration or other factors during AOD furnace operation, ensuring that the connection between the air gun and the metal hose remains secure. When the air gun needs to be disassembled, first slide the limiting sleeve 13 in the reverse direction to disengage the locking block 15 from the locking groove 14, and then pull out the connecting pipe 5. The connecting pipe 5 will push the limiting block 8 to compress the tension spring 7, causing it to disengage from the limiting groove 9, thus completing the separation of the first connector 1 and the second connector 2. This enables the rapid disassembly of the air gun and the metal hose. The entire process is simple and efficient, effectively shortening the air gun replacement time, improving the production efficiency of the AOD furnace, and ensuring the stability and safety of the air gun during operation. This meets the working requirements of the AOD furnace, which requires frequent air gun replacement and high connection stability.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
