Description

Technical Field

[0001] This application relates to the field of welding technology, and more specifically, to a welding torch-type welding goggles and welding device. Background Technology

[0002] Currently, welders typically use head-mounted or handheld welding masks to protect themselves from arc light and spatter during welding operations. However, head-mounted masks are stuffy and can cause neck fatigue during prolonged use. Furthermore, the need to manually flip the mask at the moment of arc initiation can lead to eye damage due to light leakage caused by delayed operation. Handheld masks, on the other hand, require one hand to operate, making it impossible to coordinate both hands during welding, which affects welding stability and work efficiency. Summary of the Invention

[0003] This application provides at least one welding torch-type welding goggle and welding device. The welding torch-type welding goggle can be directly installed on the welding torch and can block the strong light of the electric arc in any line of sight in front of the welder, thereby achieving protection while making up for the shortcomings of head-mounted or handheld welding masks.

[0005] In one optional embodiment, the clamping and fixing assembly includes a clamp and a locking member, wherein the clamp is sleeved on the welding handle and the locking member is used to tighten the clamp.

[0008] In one optional embodiment, the universal adjustment mechanism further includes a damping limiting member disposed between the ball seat and the ball head shaft, so that the ball head shaft can maintain its angle relative to the ball seat when no external force is applied.

[0009] In one optional embodiment, the damping limiting member is a damping pad, which is fitted onto the ball joint shaft and used to maintain the angle of the ball joint shaft relative to the ball seat by friction.

[0010] In one optional embodiment, the light-blocking lens assembly includes a lens retainer and a light-blocking lens, the lens retainer being connected to the universal adjustment mechanism, and the light-blocking lens being installed inside the lens retainer.

[0011] In one optional embodiment, the light-shielding lens is an auto-dimming lens that can automatically darken when an electric arc light is detected and return to transparency after the electric arc light is extinguished.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] refer to Figure 1 This application provides a welding apparatus, including a welding torch 1. The welding torch 1 is used to fix a welding rod and efficiently transmit the high current of the welding power source to the end of the welding rod, igniting and maintaining the electric arc.

[0023] refer to Figure 1 The welding device also includes a welding torch-type welding goggle, which includes a clamping and fixing component 10, a universal adjustment mechanism 20, and a light-shielding lens assembly 30. The clamping and fixing component 10 is used to install and fix the goggle to the handle of the welding torch 1. The universal adjustment mechanism 20 is connected to the clamping and fixing component 10. The light-shielding lens assembly 30 is connected to the universal adjustment mechanism 20. The universal adjustment mechanism 20 is configured to enable the light-shielding lens assembly 30 to rotate 360° and adjust its pitch angle relative to the welding torch 1, so as to block the strong arc light in front of the welder's eyes. In actual use, the welder installs the welding torch-type welding goggle on the handle of the welding torch 1 through the clamping and fixing component 10, and adjusts the angle of the light-shielding lens assembly 30 through the universal adjustment mechanism 20. This allows the light-shielding lens assembly 30 to move synchronously with the welding torch 1 and to block the strong arc light in any line of sight in front of the welder, thereby achieving protection while compensating for the shortcomings of head-mounted or handheld welding masks.

[0024] It should be noted that the 360° rotation of the light-shielding lens assembly 30 relative to the welding torch 1 actually refers to the rotation of the light-shielding lens assembly 30 around a direction perpendicular to the axis of the welding torch 1. The pitch angle adjustment of the light-shielding lens assembly 30 relative to the welding torch 1 actually refers to the rotation of the light-shielding lens assembly 30 around the axis of the welding torch 1.

[0025] In some embodiments, the clamping and fixing assembly 10 includes a clamp 11 and a locking member 12. The clamp 11 has an arc-shaped or ring-shaped structure and is used to be fitted onto the handle of the welding torch 1. The locking member 12 can be a bolt, nut, or quick-release clip structure. By tightening or locking the locking member 12, the clamp 11 is tightened, thereby firmly fixing the welding torch-type welding goggles onto the handle of the welding torch 1.

[0026] In some embodiments, the clamp 11 is an elastic clamp. The elastic clamp can be made of spring steel or highly elastic engineering plastic and has a certain preload. When used in conjunction with the locking element 12, the elastic clamp can adapt to welding handles of different thicknesses, enabling quick tool-free installation and disassembly, greatly improving the versatility and portability of the device.

[0027] In some embodiments, the universal adjustment mechanism 20 includes a ball seat 21 and a ball head pivot 22. The ball seat 21 is connected to the clamping and fixing assembly 10, such as when the ball seat 21 is connected to the outer surface of the clamp 11. One end (spherical) of the ball head pivot 22 is rotatably engaged with the spherical inner cavity of the ball seat 21, and the other end extends out and is connected to the light-shielding lens assembly 30. This ball head and ball seat 21 engagement structure constitutes a simple ball hinge, providing the light-shielding lens assembly 30 with multi-degree-of-freedom adjustment capability, enabling the light-shielding lens assembly 30 to rotate 360° and adjust its pitch angle relative to the welding torch 1.

[0028] In some embodiments, the universal adjustment mechanism 20 further includes a damping limiting member (not shown in the figure), which is disposed between the ball seat 21 and the ball head shaft 22, so that the ball head shaft 22 can maintain its angle relative to the ball seat 21 when no external force is applied. That is, when the operator turns the light-shielding lens assembly 30 to the desired angle, the limiting force provided by the damping limiting member can keep the ball head shaft 22 locked at its angle relative to the ball seat 21 when no external force is applied. This can prevent the lens from automatically drooping or deflecting due to gravity or vibration, thereby ensuring the stability after adjustment.

[0029] In some embodiments, the damping limiting member is a damping pad, which is fitted onto the ball joint shaft 22 and used to maintain the angle of the ball joint shaft 22 relative to the ball seat 21 through friction. For example, the damping pad is fitted onto the end of the ball joint shaft 22 that mates with the ball seat 21. In the installed state, the damping pad is compressed and contracted by the ball seat 21 and the ball joint shaft 22, so that the ball joint shaft 22 needs to overcome the friction between the ball joint shaft 22 and the damping pad to rotate relative to the ball seat 21. This structure is simple, reliable, inexpensive, and provides a long-lasting and stable damping effect.

[0030] It should be noted that a locking nut can be provided on the ball seat 21 to adjust the size of its spherical inner cavity. By adjusting the pressure of the locking nut, the compression of the damping pad can be changed, thereby fine-tuning the magnitude of the damping force.

[0031] In some embodiments, the light-blocking lens assembly 30 includes a lens retainer 31 and a light-blocking lens 32. The lens retainer 31 is made of lightweight plastic or metal and is connected to the universal adjustment mechanism 20. The light-blocking lens 32 is installed in the lens retainer 31 by snap-fitting, embedding, or screw fixing.

[0032] In some embodiments, the light-blocking lens 32 is an automatic light-changing lens, which automatically darkens when it detects arc light and returns to transparency after the arc light is extinguished. For example, the automatic light-changing lens integrates a light sensor and a liquid crystal light-changing layer. Under normal conditions (when no arc is ignited), the lens maintains high transparency, allowing the welder to clearly observe the weld position; once a specific wavelength of light generated by the welding arc light is detected, the lens rapidly darkens (becomes darker) within milliseconds, effectively filtering harmful ultraviolet rays, infrared rays, and strong visible light; when the arc light is extinguished, the lens automatically returns to a transparent state. This design solves the defects of traditional dark-colored filters, which result in dim visibility and inconvenient observation during non-welding periods, significantly improving the safety and efficiency of welding operations.

[0033] The welding torch-type welding goggles of this application integrate the light-shielding lens assembly 30 with the welding torch 1 via the clamping and fixing assembly 10 and the universal adjustment mechanism 20, which can completely free the welder's hands to achieve two-handed operation; at the same time, the universal adjustment mechanism 20 gives the light-shielding lens assembly 30 a flexible adjustment capability of 360° rotation and pitch angle, so that it can move synchronously with the welding torch 1 and be accurately positioned in front of the welder's line of sight, effectively blocking the strong light of the electric arc at the moment of arc ignition, thereby eliminating the hidden dangers of cumbersome operation and delayed response of traditional protective equipment, and greatly improving the convenience, safety and overall efficiency of welding operations.
