[0002] The main function of the shielding gas is to prevent the welding area from being polluted by harmful gases such as oxygen and nitrogen in the atmosphere, thereby protecting the quality and performance of the weld metal.

[0003] However, in the prior art, during the welding process, when using an adapter sleeve to connect the shielding gas, if the pursuit of quick installation ignores the sealing performance, it is very easy to cause the leakage of the shielding gas. Once the adapter leaks, the flow rate and purity of the shielding gas will be directly affected, and then the welding area will be externally polluted, resulting in defects such as pores and slag inclusions in the weld, thereby significantly reducing the welding quality. More seriously, if the leakage of the shielding gas reaches a certain level, it will also cause an abnormal decrease in the oxygen concentration in the welding area, forming a potential oxygen-deficient environment, posing a threat to the health of welders, and increasing safety risks such as fires and explosions.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1: As Figure 1 - Figure 3 shown, the present utility model provides an adapter for quickly connecting a protective gas during welding, including an outer shell main body 1. A plurality of sealing grooves 11 are sequentially opened inside the outer shell main body 1. Sealing rings 5 are installed inside each of the plurality of sealing grooves 11. The multiple sealing grooves 11 are sequentially distributed on the inner wall of the outer shell main body 1. A threaded port 12 is opened inside one end of the outer shell main body 1. And a connector 6 is arranged inside one end of the outer shell main body 1. A threaded head 61 is opened on the outer surface of one end of the connector 6. The threaded head 61 is threadedly connected to the threaded port 12. One end of the outer shell main body 1 is fixedly connected with a connecting port 4. A locking mechanism 2 is installed on the outer surface of the connecting port 4. A soft cap 3 is arranged at one end of the outer shell main body 1. The soft cap 3 is sleeved on the outer surface of the connector 6. A protective sleeve 41 is fixedly connected to the outer surface of one end of the connecting port 4.

[0026] The following specifically describes the specific settings and functions of this embodiment. The multiple sealing grooves 11 designed inside the outer shell main body 1 not only reflect the strict requirements for sealing performance, but also achieve the precise positioning and hierarchical installation of the sealing rings 5 through the sequential distribution of the inner diameters. Ensure that each sealing ring 5 can play its best sealing role under different pressures and working environments.

[0027] According to the needs of the installation position and working environment, the sealing ring 5 is configured in the corresponding sealing groove 11. These sealing rings 5 are usually made of materials with good elasticity, wear resistance, and corrosion resistance, such as rubber, silicone, or certain special synthetic materials. They can deform under pressure and closely fit on the contact surface, thus effectively preventing medium leakage. At the same time, the use of multiple sealing rings 5 stacked together further enhances the sealing effect and improves the overall safety and reliability of the device.

[0028] The connector 6 is a key component for connecting to external devices. Through the threaded head 61 being tightly fitted with the threaded port 12 inside the housing main body 1, the connector 6 is firmly installed in the designated position. This threaded connection method is not only convenient for installation and disassembly but also has a certain self-locking property, which can prevent loosening caused by vibration or external forces to a certain extent.

[0029] Before use, sleeving the soft cap 3 on the outer surface of one end of the connector 6 is an effective protection measure. The soft cap 3 is usually made of soft, wear-resistant, and aging-resistant materials, such as silicone or rubber. It can closely fit on the outer surface of the connector 6, preventing contaminants such as dust, impurities, or moisture from entering the inside of the connector 6, thus keeping the connector 6 clean and dry. In addition, the soft cap 3 can also relieve the impact and damage caused to the connector 6 by accidental collisions or drops to a certain extent.

[0030] Embodiment 2: As Figure 3 and Figure 4 shown, the locking mechanism 2 includes two clamping plates 22. One end of the clamping plate 22 is fixedly connected with a rotating block 23, and the other end of the clamping plate 22 is fixedly connected with a transfer block 28. On one side of the two clamping plates 22, there is a first connecting plate 21. Both the top and bottom of the first connecting plate 21 are provided with first connecting grooves 211. The inside of the first connecting groove 211 is rotationally connected with the rotating block 23, and the two clamping plates 22 are sleeved on the outer surface of the protective sleeve 41. One of the transfer blocks 28 is rotationally connected with a rotating frame 24, and the top of the rotating frame 24 is rotationally connected with a second connecting plate 27. The bottom of the second connecting plate 27 is provided with a second connecting groove 25, and the inside of the second connecting groove 25 is rotationally connected with the other transfer block 28. The top side wall of the second connecting plate 27 is fixedly connected with a handle 26.

[0031] The effect achieved by the entire embodiment is that, first of all, the connection port 4 not only ensures seamless docking with the protective gas storage device but also can withstand the pressure fluctuations that may occur during gas transmission. At this time, the protective sleeve 41 not only provides an additional protective barrier for the connection port 4 to prevent damage caused by the external environment or improper operation but also can reduce the risk of gas leakage to a certain extent, ensuring the safety of the connection.

[0032] Pull the handle 26. Through the lever principle, only a small force needs to be applied to drive the operation of the entire connecting mechanism. As the handle 26 is pulled, the second connecting plate 27 starts to move, forming a linkage mechanism with the rotating frame 24 through the adapter block 28.

[0033] Driven by the adapter block 28, the two clamping plates 22 gradually approach the protective sleeve 41. During this process, the rotating block 23 rotates flexibly within the first connecting groove 211. This not only ensures that the clamping plates 22 can move smoothly along the predetermined trajectory but also allows for fine-tuning according to the shape and size of the protective sleeve 41 to ensure the tightness and uniformity of the clamping. This design reflects the pursuit of perfection in details and a deep understanding of user needs.

[0034] Finally, when the two clamping plates 22 completely squeeze the protective sleeve 41, the entire connection process is completed. This tight and firm connection method not only greatly improves the efficiency and stability of gas transmission but also effectively reduces the risk of leakage. At the same time, this connection mechanism also has the advantages of being easy to disassemble and reinstall, providing great convenience for subsequent maintenance and repair work.

[0035] Usage method and working principle of this device: During installation, the outer shell main body 1 is used for connection and installation, and multiple sealing grooves 11 arranged in sequence according to the inner diameter size are provided on its inner side. Subsequently, we install sealing rings 5 with different inner diameters in these sealing grooves 11 one by one to enhance the sealing effect and prevent leakage.

[0036] For the installation of the connector 6, we connect it to the threaded port 12 of the outer shell main body 1 through the threaded head 61. Before use, to protect the connector 6, we use a soft cap 3 to cover the outer surface of one end of it.

[0037] After the connection is completed, when the connection port 4 is connected to the protective gas storage device, the protective sleeve 41 provides additional protection. At this time, by pulling the handle 26, the second connecting plate 27 can be driven to move, and then an adapter block 28 is driven to move. With the assistance of the rotating frame 24, the two adapter blocks 28 act simultaneously, each driving the two clamping plates 22 to approach the protective sleeve 41. During this process, the rotating block 23 works together with the first connecting plate 21 within the first connecting groove 211 to achieve rotation, so that the two clamping plates 22 gradually clamp the protective sleeve 41 to enhance the stability of the connection and prevent leakage.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
