Description

Technical Field

[0001] This utility model relates to the field of welding safety glasses technology, specifically a structure for welding safety glasses. Background Technology

[0002] Electric welding is essential in the construction of structures. However, electric welding involves strong discharge and intense light radiation, which can greatly damage the eyesight of welders. Traditionally, protective goggles are used for electric welding.

[0003] However, the goggles need to be held with one hand, so you have to use one hand to weld and the other to hold the goggles. When you need to observe the welding position, you have to put the goggles down, which is inconvenient.

[0004] The existing technology CN201310392975.9 electric welding protective mask has improved the working method by combining the mask with goggles; however, it is still necessary to frequently remove it to observe the welding situation on site.

[0005] To address these issues, we have developed a special protective goggle structure for welders. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a special protective goggles structure for electric welders, so as to solve the technical problem that electric welders need to frequently pick up and put down protective masks and cannot work with both hands at all times.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a structure for protective goggles for welders, including a frame, a photochromic lens mounted on the frame, the photochromic lens comprising at least two pairs of glass substrates, with a transparent conductive layer disposed opposite to each pair of glass substrates; an ion storage layer disposed on one pair of transparent conductive layers, an electrochromic layer disposed on the other pair of transparent conductive layers; and an ion conductor layer disposed between the electrochromic layer and the ion storage layer.

[0008] A transparent conductive layer between a glass substrate and an ion storage layer is used as the cathode, and a transparent conductive layer between a glass substrate and an electrochromic layer is used as the anode.

[0009] It also includes a fireproof electrical control line, an electrical control board, a battery pack, and a contact button. One end of the fireproof electrical control line is connected to the contact button, and the other end is connected to the electrical control board. An installation cavity is set inside the eyeglass frame, and the battery pack is fixedly installed in the installation cavity. The two ends of the battery pack are connected to the cathode and anode through the electrical control board, and the opening and closing of the battery pack and the photochromic lens are controlled by the fireproof electrical control line.

[0010] The contact button is adapted to be mounted on the welding handle of an external welding clamp.

[0011] In a further technical solution, the eyeglass frame includes temples, and a transition channel is provided inside the temples, with the fireproof electrical control line installed inside the transition channel.

[0012] In a further technical solution, a circular frame is hinged to the outside of the eyeglass frame, and a magnifying glass is installed inside the circular frame.

[0013] In a further technical solution, a central body is installed in the middle of the eyeglass frame, and a battery pack is installed in the central body; and a position cavity is reserved on one side inward, and an electronic control board is installed in the position cavity;

[0014] An extension plate is provided outside the circular frame, and the extension plate bends outward; a notch is provided on the outer side of the central body, and the extension plate is adapted to be movably installed in the notch.

[0015] In a further technical solution, four sets of reserved plates are provided at the bottom of the eyeglass frame, and a mounting hole is provided on the reserved plates;

[0016] A bottom cover is detachably installed on the reserved plate, and a connecting plate is installed on the bottom cover, with two mounting holes on the connecting plate;

[0017] A positioning screw is installed between mounting hole one and mounting hole two.

[0018] In a further technical solution, a connecting part is provided on the outer side of the temple, and two sets of connecting parts are provided, with a positioning strap installed between them. The positioning strap is divided into a sub strap and a main strap, one end of which is fixedly connected to the connecting part; the other end of the main strap is provided with a ladder buckle, which is suitable for the sub strap to be wrapped and connected.

[0019] In a further technical solution, a connecting clamp is installed under the contact button, the connecting clamp is sleeved on the welding handle, and is locked by a locking bolt installed at the end of the connecting clamp; a support part is fixedly provided on the connecting clamp, and the contact button is installed on the support part.

[0020] In a further technical solution, the electronic control board is equipped with indicator lights that extend to the outside of the eyeglass frame; a charging interface, which is a mini USB, is provided outside the battery pack.

[0021] The structure of a transparent electrochromic glass lens consists of two glass substrates and five thin film layers sandwiched between them. The transparent conductive layer (TC), together with the glass substrates, forms the transparent conductive glass, serving as a transparent electrode. Commonly used transparent conductive layer materials include indium tin oxide (ITO) and aluminum-doped zinc oxide (AZO) films. The ion storage layer (CE) plays a role in ion balance, providing and storing the ions required for color change, and uses reversible redox materials such as polyaniline or polypyrrole. The ion conductor layer (IC) conducts the ions required for the color-changing reaction. The electrochromic layer (EC) is the core of the entire electrochromic glass and is the layer where the color-changing reaction occurs. In this device, the transparent conductive layer uses nano-silver electrode plates with a nanometer thickness, resulting in high light transmittance.

[0022] Electric welding generates electrical sparks and heat. To ensure the materials can withstand high temperatures, the electrochromic material used in the electrochromic layer can be inorganic materials such as tungsten oxide (WO3) or V2O5. The blue light produced by welding is quite harmful to the human eye. To reduce the intensity of blue light, the glass substrate of the glasses uses orange-tinted glass, which is the complementary color limit of blue light.

[0023] When welding operations begin, pressing the contact button triggers the lens drive module within the control board, causing the photochromic glasses to switch to dark protection mode within 0.2-0.5 seconds. The glasses are connected to the lens drive module via wires.

[0024] Compared with existing technologies, it has the following advantages:

[0025] This invention combines photochromic lenses with a contact button, allowing the conductive circuit of the photochromic lenses to be switched on and off by pressing the contact button on the welding handle when the glasses are worn. This enables the photochromic lenses to change color while powered on, filtering out blue light and reducing the harm of directly viewing strong blue light.

[0026] This invention incorporates a magnifying glass mounted on the external hinge of photochromic glasses, enabling observation of local weld connections after power is off. The magnifying glass allows for detailed observation of specific areas.

[0027] The bottom of the eyeglass frame of this invention can be detachably fitted with a bottom face shield, providing safety protection during welding work. The positioning straps secure the frame to the head. Attached Figure Description
