[0002] In the field of modern industrial welding, gas shielded welding (GSW) is a highly efficient and high-quality welding method widely used in many industries such as automobile manufacturing, shipbuilding, and steel structure engineering. During GSW, the welding torch connection device is a key component, and its performance directly affects the welding quality and efficiency.

[0003] Currently, existing gas-shielded welding wire torch connection devices often struggle to achieve convenient and precise adjustment of the wire exit angle during use. Traditional devices have complex angle adjustment structures, requiring operators to perform cumbersome operations with tools, resulting in low adjustment efficiency. They cannot quickly meet the wire exit angle requirements of different welding conditions. Because traditional fastening structures often use bolts and nuts, adjustments require repeated tightening and loosening, which is not only time-consuming and labor-intensive but also prone to inaccurate angle adjustments due to human error, thus affecting welding quality and increasing the difficulty and cost of welding operations. Therefore, to address the problems of complex angle adjustment structures, cumbersome operations requiring tools, and low adjustment efficiency in existing traditional devices, a gas-shielded welding wire torch connection device with an adjustable wire exit angle is needed.

[0031] Example 1:

[0032] like Figures 1-6 As shown, an adjustable wire feed angle gas shielded welding wire welding gun connection device includes a support block 1. A rotating rod 3 is rotatably connected to the inner wall of the support block 1. A support block 2 is provided on the outer wall of the rotating rod 3. The inner wall of the right support block 2 is fixedly connected to the outer wall of the rotating rod 3. A knob 4, a limiting block 5, a fastening ring 6, and a limiting groove 7 are provided on the left side of the outer wall of the rotating rod 3. Support plates 9 are fixedly connected to the top of the support block 1 and the bottom of the support block 2. A fixing sleeve 10 is rotatably connected to the left end of the top support plate 9. A fixing block 11 is fixedly connected to the top of the fixing sleeve 10. A ratchet plate 12 is fixedly connected to the right end of a fixed block 11. A fixed sleeve 13 is rotatably connected to the right end of a top support plate 9. A fixed block 14 is fixedly connected to the top of a fixed sleeve 13. A pawl 18 is connected to the inner wall of a fixed block 14 via a slide rod 15. The outer wall of the ratchet plate 12 is located on the inner circumference of the fixed block 14. The top of the ratchet plate 12 is located at the bottom end of the pawl 18. A fixed sleeve 19 is rotatably connected to the left end of a bottom support plate 9. A fixed sleeve 21 is rotatably connected to the right end of a bottom support plate 9. The bottom end of a fixed sleeve 19 is connected to a fixed sleeve 21 via a locking block 20 and a locking sleeve 22.

[0033] Specifically, support block 1 and support block 2 are rotatably connected by a rotating rod 3, forming the basic support frame of the device. The rotating rod 3 connects and supports support block 2, allowing support block 2 to rotate around the rotating rod 3. The knob 4, limit block 5, fastening ring 6, and limit groove 7 form a fastening assembly. The knob 4 can rotate on the rotating rod 3, causing the limit block 5 to move within the limit groove 7. Through the shallow to deep grooves in the limit groove 7, the position of the fastening ring 6 is adjusted, thereby controlling support block 1. The fastening and loosening states between the support block 1 and support block 2 are as follows: When the knob 4 drives the limiting block 5 to slide from shallow to deep within the limiting groove 7, the fastening ring 6 will move to the left, loosening the connection between the support block 1 and support block 2. At this time, the support block 1 or support block 2 can be rotated around the rotating rod 3 to adjust the angle between the welding gun tube and the welding wire tube. Conversely, when the limiting block 5 returns from deep to shallow, the fastening ring 6 tightens to the right, locking the current angle by squeezing the rubber gasket 8 between the support block 1 and support block 2 using friction. Because the gasket 8 has a certain elasticity and is placed between the support block 1 and support block 2, it not only buffers vibration but also enhances the stability after locking, preventing the angle from shifting due to slight external forces. Furthermore, the contact surface between the fastening ring 6 and the rotating rod 3 has anti-slip textures, which can improve the friction between the fastening ring 6 and the rotating rod 3. The support plate 9 is used to connect the fixing sleeve 10, fixing sleeve 23, fixing sleeve 319, and fixing sleeve 421, providing support for these components. The mounting supports are installed. Fixing sleeve 10 and fixing sleeve 2 13 are used to fit onto the welding gun tube. Fixing block 1 11 and fixing block 2 14 are connected to fixing sleeve 10 and fixing sleeve 2 13 respectively. The ratchet plate 12 and the pawl 18 cooperate to clamp and fix the welding gun tube under the action of sliding rod 15, limiting plate 16 and spring 17. Fixing sleeve 3 19 and fixing sleeve 4 21 are used to fit onto the welding wire tube. The locking block 20 and the locking sleeve 22 cooperate to lock the fixing sleeve 3 19 and fixing sleeve 4 21.

[0034] The knob 4 is located on the left side of the outer wall of the rotating rod 3. The inner wall of the knob 4 is rotatably connected to the outer wall of the rotating rod 3. The right end of the knob 4 is fixedly connected to the limit block 5. The left side of the outer wall of the rotating rod 3 is slidably connected to the fastening ring 6. The left end of the fastening ring 6 has a limit groove 7. The limit block 5 is slidably connected in the limit groove 7 at the left end of the fastening ring 6. The limit groove 7 is a groove that gradually deepens from shallow to deep. That is, the shallow groove on the top side of the left end of the fastening ring 6 gradually transitions to the deep groove on the front side of the left end of the fastening ring 6. The locking block 20 is located at the bottom end of the fixing sleeve 3 19. The bottom end of the fixing sleeve 4 21 is fixedly connected to the locking sleeve 22. The outer wall of the locking block 20 is set on the inner circumference of the locking sleeve 22. A gasket 8 is set between the support block 1 and the support block 2. The gasket 8 is made of rubber. The bottom end of the locking sleeve 22 is fixedly connected to the fixing rod 23.

[0035] Specifically, the gasket 8 has a certain elasticity and is set between support block 1 and support block 2 to buffer and increase friction, prevent support block 1 and support block 2 from directly contacting and wearing each other, and enhance the fastening stability between them. The cooperation of the locking block 20 and the sleeve 22 allows the fixing sleeve 3 19 and fixing sleeve 4 21 to be quickly locked and disassembled. The fixing rod 23 makes it easy for the operator to pry the sleeve 22 to produce a slight deformation, so as to realize the insertion and removal of the locking block 20 and the sleeve 22.

[0036] Example 2:

[0037] As one of the optimized structural designs for Example 1, such as Figures 1-6 As shown, the slide rod 15 is located on the inner wall of the fixed block 14. The outer wall of the slide rod 15 is slidably connected to the inner wall of the fixed block 14. The bottom end of the slide rod 15 is fixedly connected to the top end of the pawl 18. The bottom side of the outer wall of the slide rod 15 is fixedly connected to the limiting piece 16. The outer wall of the limiting piece 16 is slidably connected to the inner wall of the fixed block 14. A spring 17 is provided on the outer wall of the slide rod 15. One end of the spring 17 is connected to the inner wall of the fixed block 14, and the other end of the spring 17 is connected to the top end of the limiting piece 16.

[0038] Specifically, the slide bar 15 is used to connect the pawl 18 and the second fixed block 14, allowing the pawl 18 to slide up and down within the second fixed block 14. The limiting plate 16 is used to limit the sliding range of the slide bar 15 and prevent the slide bar 15 from sliding out of the second fixed block 14. The spring 17 provides a restoring force. When the slide bar 15 is pulled upward, the spring 17 is compressed. After the pulling force is released, the spring 17 pushes the limiting plate 16 and the slide bar 15 downward, so that the pawl 18 is reset and cooperates with the ratchet plate 12 to achieve one-way locking.

[0039] Working principle: Fixing sleeve 10 and fixing sleeve 23 are placed on the welding torch tube. Pulling the slide rod 15 upward compresses the spring 17, causing the pawl 18 to move upward. Then, the ratchet plate 12 extending from fixing block 11 is inserted into fixing block 24, placing it at the bottom of the pawl 18. The force applied to the slide rod 15 is released, and under the action of the pawl 18 and spring 17, the ratchet plate 12 can only move in one direction, allowing fixing sleeve 10 and fixing sleeve 23 to clamp onto welding torch tubes of different diameters. Next, fixing sleeve 319 and fixing sleeve 421 are placed on the welding wire tube. Bending the fixing rod 23 causes a slight deformation of the retaining sleeve 22, allowing the retaining block 20 on fixing sleeve 319 to be inserted into the retaining sleeve 22 on fixing sleeve 421, thus locking fixing sleeve 319 and fixing sleeve 421 together. When it is necessary to remove fixing sleeve 10 and fixing sleeve 23 from the welding torch later... When disassembling the tube, simply pull the slide bar 15 upwards to move the pawl 18, causing the pawl 18 to release its restriction on the ratchet plate 12. Then, pull the ratchet plate 12 out of the fixing block 14 to remove the fixing sleeve 10 and fixing sleeve 13 from the welding gun tube. When it is necessary to adjust the angle between the welding gun tube and the welding wire tube, turn the knob 4 to move the limiting block 5 within the limiting groove 7 on the fastening ring 6. When the limiting block 5 moves to the appropriate position, the fastening between the support block 1 and the support block 2 is released. Then, the support block 1 or the support block 2 can be rotated to adjust the angle between the welding gun tube and the welding wire tube. When the appropriate position is reached, turn the knob 4 in the opposite direction to move the limiting block 5 along the trajectory of the limiting groove 7. When the limiting block 5 moves to the shallowest position of the limiting groove 7, the support block 1 and the support block 2 can be locked to maintain the angle between the welding gun tube and the welding wire tube.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
