Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding gun cables, and more particularly to a combined carbon dioxide welding gun cable. Background Technology
[0002] When a carbon dioxide gas shielded welding torch is in operation, a special cable with an internal gas guide tube is required. The main function of the gas guide tube in the carbon dioxide welding torch is to guide the gas into the welding torch, ensuring a stable gas supply during the welding process. During the welding process, carbon dioxide gas plays a protective role, preventing oxygen in the air from reacting with the molten metal, thereby ensuring the quality of the weld.
[0003] Patent No. (CN209708658U) discloses a combined CO2 welding gun cable, including a cable body. The cable body consists of a gas guide tube, a sheath fitted outside the gas guide tube, an isolation layer located between the gas guide tube and the sheath, a cable conductor arranged between the gas guide tube and the isolation layer, and multiple control wires. The gas guide tube is also provided with a support soft spring supported on the inner wall of the gas guide tube. The support soft spring is provided with several balls, and the two ends of the support soft spring are provided with limiting blocks to prevent the balls from sliding out. The outer side wall of the gas guide tube is also provided with protrusions arranged along the axial direction of the gas guide tube. In this invention, the supporting soft spring serves to support the air guide tube, preventing it from bending and deforming. The ball bearings reduce the friction when the supporting soft spring is inserted into the air guide tube and provide rigid support from the spring during bending, thus reducing damage to the air guide tube caused by the supporting soft spring. When the cable body bends, the convex strip provides a certain lifting effect on the outer wall of the air guide tube, preventing airflow obstruction due to bending. However, existing combined CO2 welding gun cables are mostly integrated structures with the air guide tube built-in, resulting in a large overall cable volume, affecting mobility after installation, and requiring complete replacement when the cable is damaged, increasing maintenance costs.
[0004] Therefore, in view of the fact that the existing combined CO2 welding gun cables are mostly integrated structures, resulting in a large overall cable volume and high maintenance costs, a combined CO2 welding gun cable can be designed to achieve a combined structure, which facilitates the replacement of gas pipes or cables and reduces maintenance costs. Utility Model Content
[0005] In order to overcome the problem that existing combined CO2 welding gun cables are mostly integrated structures, resulting in a large overall cable size and high maintenance costs.
[0006] The technical solution of this utility model is as follows: a combined carbon dioxide welding gun cable, including a cable sheath and a gas duct sheath. An isolation layer is provided on the inner side of the cable sheath, and the cable core is wrapped on the inner side of the isolation layer. A gas duct body is provided on the inner side of the gas duct sheath, and a metal support mesh layer is provided in the gas duct body. An isolation cavity is opened inside the gas duct sheath. A connecting seat is provided on the outer side of the surface of the cable sheath, and a locking seat is provided on the outer side of the surface of the gas duct sheath.
[0007] Preferably, the cable and air duct are assembled by connecting the connector and the locking seat to form a flat cable. When a single structure is damaged, only the damaged part needs to be replaced, which reduces maintenance costs and reduces the overall structure, thus improving practicality.
[0008] Preferably, the isolation layer is made of composite non-woven fabric, and a rubber insulating layer is provided on the surface of the isolation layer.
[0009] Preferably, a positioning strip is provided on the inner side of the air guide tube body, and the positioning strip and the air guide tube body are integrally formed.
[0010] Preferably, the metal support mesh layer is made of metal wires woven in a spiral shape.
[0011] As a preferred option, the isolation chamber has an arc-shaped structure design, and a buffer column is installed in the isolation chamber. The buffer column is made of elastic resin.
[0012] Preferably, the surface of the connector is provided with snap-fit grooves, which are evenly spaced, and the surface of the connector is provided with snap-fit blocks, which correspond one-to-one with the snap-fit grooves.
[0013] Preferably, the snap-fit block has a trapezoidal structure design, and the snap-fit block and the snap-fit slot are snapped together.
[0014] The beneficial effects of this utility model are:
[0015] This modular CO2 welding torch cable allows for the combined connection of the cable sheath and the gas duct sheath. The connection is achieved through the snap-fit of the snap-fit block and the snap-fit groove, which connects and fixes the connector and the snap-fit seat to form a flat cable structure. This reduces the overall size of the cable structure and facilitates installation and use. At the same time, the cable core and the gas duct body are separate structures, so only the part needs to be replaced when either is damaged, reducing maintenance costs. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-4 This utility model provides an embodiment: a combined CO2 welding gun cable, including a cable sheath 1 and a gas duct sheath 2. An isolation layer 3 is provided on the inner side of the cable sheath 1. The isolation layer 3 is made of composite non-woven fabric, and a rubber insulation layer is provided on the surface of the isolation layer 3. A cable core 4 is wrapped inside the isolation layer 3. A gas duct body 5 is provided on the inner side of the gas duct sheath 2, and a metal support mesh layer 6 is provided inside the gas duct sheath 2. An isolation cavity 7 is opened inside the gas duct sheath 2. A connecting seat 8 is provided on the outer side of the surface of the cable sheath 1, and a locking seat 9 is provided on the outer side of the surface of the gas duct sheath 2. The cable and the gas duct are assembled by connecting the connecting seat 8 and locking seat 9 to form a flat cable. When a single structure is damaged, only the affected part needs to be replaced, reducing maintenance costs and improving the overall structural integrity and practicality.
[0023] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a positioning strip is provided on the inner side of the air duct body 5. The positioning strip and the air duct body 5 are integrally formed. The metal support mesh layer 6 is made of metal wire woven in a spiral shape. The isolation cavity 7 has an arc-shaped structure design. A buffer column is provided in the isolation cavity 7. The buffer column is made of elastic resin material. The structural strength of the air duct body 5 is increased by the metal support mesh layer 6. The isolation cavity 7 is opened in the outer air duct sheath 2 to achieve protection.
[0024] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, the surface of the connector 8 is provided with snap-fit grooves 81, which are evenly distributed. The surface of the snap-fit seat 9 is provided with snap-fit blocks 91, which correspond one-to-one with the snap-fit grooves 81. The snap-fit blocks 91 are designed with a trapezoidal structure. The snap-fit blocks 91 and the snap-fit grooves 81 are snapped together. The snap-fit blocks 91 are snapped into the snap-fit grooves 81, so that the connector 8 and the snap-fit seat 9 are connected and fixed, which facilitates the disassembly and replacement of the cable and the air duct.
[0025] During operation, the snap-fit block 91 is snapped into the snap-fit slot 81, so that the connecting seat 8 and the snap-fit seat 9 are connected and fixed. Through the connection of the connecting seat 8 and the snap-fit seat 9, the cable and the air duct are assembled to form a flat cable. The combination forms a flat cable structure, which reduces the volume of the overall cable structure and facilitates installation and use. The cable core 4 and the air duct body 5 are separate structures. In the event of damage to one of them, only the part needs to be replaced, reducing maintenance costs. At the same time, the structural strength of the air duct body 5 is increased by the metal support mesh layer 6, and the isolation cavity 7 is opened in the outer air duct sheath 2 to achieve protection.
[0026] Through the above steps, the cable and air duct are assembled by connecting the connector 8 and the locking seat 9 to form a flat cable. When a single structure is damaged, only the damaged part needs to be replaced, reducing maintenance costs. At the same time, the overall structure is reduced, improving practicality. This solves the problem that existing combined CO2 welding gun cables are mostly integrated structures, resulting in a large overall cable volume and high maintenance costs.
