Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a quick-change plug used on an argon arc welding gun. Background Art

[0002] At present, the welding gun is one of the important tools that are indispensable for welding operations in industrial production and processing. The working principle of the welding gun is to use the high current and high voltage of the welding machine to generate heat that is gathered at the gun head, melting the welding wire. The molten welding wire penetrates into the part to be welded, and after cooling, the objects to be welded are firmly connected into one. Argon arc welding is a welding technology that uses argon as a shielding gas. It is also called argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area. The structural design of the existing gas-to-water conversion plug on the argon arc welding gun is relatively complex, and the assembly is relatively cumbersome. In addition, the quick conversion plug has the defects of unreliable performance, short service life, and inconvenient installation. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a quick-change plug with a simple structure, stable and reliable performance, convenient assembly, long service life and convenient installation.

[0004] To achieve the above-mentioned purpose, the present invention adopts a quick conversion plug, including a connector body and a rubber protective sleeve wrapped around the connector body, the rubber protective sleeve including a first sleeve and a second sleeve arranged on the first sleeve, a clamping cavity for wrapping around the connector body is formed between the first sleeve and the second sleeve, one end of the connector body has a threaded connection port exposed outside the rubber protective sleeve, one side of the connector body has a bent pipe portion connected to the threaded connection port, the bent pipe portion extends outside the rubber protective sleeve, and the other end of the connector body has a plug-in portion exposed outside the rubber protective sleeve.

[0005] The beneficial effects of the above structure are as follows: the connector body has threaded connections and plug-in portions at both ends, facilitating installation of the connector body with a welding gun or welding machine, making installation more convenient. Furthermore, the rubber protective sleeve is wrapped around the connector body through the first and second sheaths, facilitating assembly of the quick-change plug and improving assembly efficiency. The connector body adopts an integrated structural design, which simplifies the design and prolongs its service life. Consequently, the quick-change plug has the advantages of a simple structure, stable and reliable performance, easy assembly, a long service life, and convenient installation.

[0006] In particular, the connector body is provided with two stopper protrusions, and the first and second sheaths are provided with stopper grooves that engage with the stopper protrusions, respectively. The stopper protrusions of the connector body engage within the first and second sheaths, thereby ensuring a more compact connection between the connector body and the first and second sheaths.

[0007] In particular, the tail of the bend is provided with an anti-slip limit groove, which can prevent the bend from slipping off and ensure a stronger connection between the bend and the water pipe.

[0008] In particular, the first and second sheaths are passed through by a plurality of bolts and are tightened with a plurality of nuts. The first and second sheaths are connected by the bolts and nuts, thereby facilitating the assembly of the first and second sheaths and achieving higher assembly efficiency.

[0009] In particular, a plurality of anti-skid grooves are respectively provided on the outer peripheral walls of the first and second protective sleeves, which can play an anti-skid role, thereby facilitating the installation of the quick-change plug. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 This is a cross-sectional view of an embodiment of the present invention.

[0012] Figure 3 This is an exploded view of an embodiment of the present utility model. DETAILED DESCRIPTION

[0013] like Figures 1 to 3 As shown, an embodiment of the present invention is a quick conversion plug, comprising a connector body 10 and a rubber protective sleeve 20 wrapped around the connector body 10, wherein the rubber protective sleeve 20 comprises a first sleeve 21 and a second sleeve 22 arranged on the first sleeve 21, and a clamping cavity 200 for wrapping around the connector body 10 is formed between the first sleeve 21 and the second sleeve 22, and the connector body 10 has a threaded connection port 11 exposed outside the rubber protective sleeve 20 at one end, and a bend portion 12 connected to the threaded connection port 11 on one side of the connector body 10, and the bend portion 12 extends outside the rubber protective sleeve 20, and the connector body 10 has a plug-in portion 120 exposed outside the rubber protective sleeve 20 at the other end.

[0014] like Figure 1 and 3As shown, the connector body 10 is provided with two stopper protrusions 13. The first and second sheaths 21 and 22 are each provided with a stopper groove 201 that engages with the stopper protrusions 13, forming a snap-fit ​​connection between the two stopper protrusions 13 and the first and second sheaths 21 and 22. The stopper protrusions of the connector body engage within the first and second sheaths, thereby ensuring a more compact connection between the connector body, the first and second sheaths. The tail end of the elbow 12 is provided with a stopper groove 121. These stopper grooves prevent the elbow from falling off, ensuring a more secure connection between the elbow and the water pipe. The first and second sheaths 21 and 22 are threaded with multiple bolts 23 and tightened with multiple nuts 24. The bolts and nuts connect the first and second sheaths, facilitating assembly and improving assembly efficiency. The outer walls of the first and second sheaths 21 and 22 are each provided with multiple anti-slip grooves 202. The anti-slip groove can play an anti-slip role, thereby facilitating the installation of the quick conversion plug.

[0015] The connector body features threaded connections and a plug-in connector at each end, facilitating installation between the connector body and a welding gun or welding machine. Furthermore, the rubber protective sleeve, wrapped around the connector body through the first and second sheaths, facilitates assembly of the quick-change plug and improves efficiency. The connector body adopts an integrated structural design, resulting in a simpler design and a longer service life. This quick-change plug offers the advantages of a simple structure, stable and reliable performance, easy assembly, a long service life, and convenient installation.
