Description

Technical Field

[0001] This utility model relates to the technical field of welding mask equipment, and in particular to a welding mask with automatic light adjustment. Background Technology

[0002] A welding mask is an essential piece of personal protective equipment used in welding operations to protect the face and eyes of welders. The welding process generates intense arc light containing large amounts of ultraviolet (UV) and infrared radiation. UV radiation primarily causes photokeratitis, leading to symptoms such as eye pain, photophobia, and tearing. Infrared radiation causes thermal damage to the eyes, and long-term exposure can lead to eye diseases such as cataracts. Welding masks effectively filter these harmful rays, protecting the eyes from damage.

[0003] Chinese patent document CN212186882U discloses a protective face shield for welding, comprising a face shield body and a transparent protective sheet. A face shield base is partially distributed in the middle of the face shield body, and a face shield rotation axis passes through the top of the face shield base. An eye-protecting face shield is installed in the middle of the face shield rotation axis, and a transparent protective sheet is attached to the outer side of the eye-protecting face shield. A brightness adjustment knob is installed in the middle of the side of the face shield body, and the face shield body rotation axis is distributed behind the brightness adjustment knob. A locking knob is fitted on the outer side of the face shield body rotation axis. A headband base passes through the inner side of the face shield body rotation axis, and a headband is connected to the inner side of the headband base. An adjustment knob is installed in the middle of the headband. This protective face shield for welding also features a night light, which is aligned with the central axis of the face shield body. When the user's working environment is dimly lit, the night light helps the user see clearly while wearing the protective face shield, allowing the user to perform welding work smoothly.

[0004] During the welding process, different welding positions and angles require different lighting angles and positions. Traditional fixed-position lighting cannot meet the requirements. Secondly, strong light needs to be blocked during the welding process to prevent external light from shining on the welding mask, which may cause glare or affect the view. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. The purpose of the present invention is to provide a welding mask with automatic dimming to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides an automatically dimming welding mask, comprising a welding mask, a fixing plate at the top of the welding mask, a sliding groove on the fixing plate, a drive motor mounted on the side of the fixing plate near the sliding groove, a lead screw connected to the output end of the drive motor, a base mounted on the lead screw, a lighting lamp mounted on the base, a control button on the side of the welding mask, an observation window on the front of the welding mask, a support plate near the upper edge of the observation window, a shielding plate hinged to one side of the support plate, and an extension plate hinged to the side of the shielding plate away from the support plate.

[0007] The welding mask with automatic light adjustment provided by this utility model also has the following technical features:

[0008] Furthermore, the base has a threaded hole, and the tail end of the lighting lamp is fixedly connected to a threaded rod, which is compatible with the threaded hole on the base.

[0009] Furthermore, sliders are provided at both ends of the bottom of the base. The sliders are embedded in the slide groove and slide in cooperation with the slide groove. The shape of the slider matches the shape of the slide groove. A nut is provided at the center of the bottom of the base. The base is connected to the lead screw by the nut.

[0010] Furthermore, the slide groove is linear in shape, the base slides in conjunction with the slide groove, and the lead screw is arranged parallel to the slide groove.

[0011] Furthermore, the shield and the extension plate are connected by a damping hinge.

[0012] Furthermore, a power interface is provided on the side of the welding mask. The power interface is electrically connected to the drive motor and the lighting lamp via wires. The power interface is used to connect an external power source to supply power to the drive motor and the lighting lamp.

[0013] Furthermore, the shielding plate and the extension plate are made of flexible plastic, and the upper surface of both the shielding plate and the extension plate is provided with a reflective coating.

[0014] Furthermore, the drive motor is a DC motor, and the drive motor is electrically connected to a control button via a wire. The control button is used to control the start, stop, and forward / reverse rotation of the drive motor.

[0015] This invention offers the following advantages: First, a lighting lamp is installed at the top of the welding mask. A drive motor is activated via a control button, causing the output of the motor to rotate the lead screw, which in turn moves the base of the lighting lamp smoothly along a sliding groove. This allows for flexible adjustment of the lighting lamp's position and quick adjustment of its direction and distance according to different welding positions and angles, ensuring optimal illumination of the welding area and effectively improving welding quality and efficiency. Second, a shielding plate is installed along the upper edge of the welding mask's observation window, effectively blocking strong external light and protecting the welder's eyesight. Furthermore, an extension plate is added to the shielding plate, further expanding the coverage and providing more comprehensive facial protection. This not only effectively prevents strong light from irritating the eyes but also blocks spatter and ultraviolet rays generated during welding to a certain extent, ensuring the safety and comfort of welders in complex working environments.

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0022] like Figures 1 to 3In one embodiment of the automatically dimming welding mask of this utility model, the automatically dimming welding mask includes a welding mask 1. A fixing plate 2 is provided at the top of the welding mask 1. A sliding groove 3 is provided on the fixing plate 2. A drive motor 4 is installed on the side of the fixing plate 2 near the sliding groove 3. A lead screw 5 is connected to the output end of the drive motor 4. A base 6 is installed on the lead screw 5. A lighting lamp 7 is provided on the base 6. A control button 8 is provided on the side of the welding mask 1. An observation window 9 is provided on the front of the welding mask 1. A support plate 10 is provided on the upper edge of the welding mask 1 near the observation window 9. A shielding plate 11 is hinged to one side of the support plate 10, and an extension plate 12 is hinged to the side of the shielding plate 11 away from the support plate 10. In this utility model, the welding mask 1 is the main structure of the device, providing face and eye protection for welding workers during welding operations. The fixing plate 2 serves as a support and fixation, providing a mounting base for the drive motor 4, lead screw 5, and base 6, ensuring that these components can operate stably during operation. The sliding groove 3 on the fixing plate 2... A sliding track is provided for the base 6 to ensure that the base 6 can move smoothly along a predetermined straight path, thereby realizing the adjustment of the position of the lighting lamp 7. The drive motor 4 on one side of the slide 3 serves as a power source to provide power for the movement of the base 6. The rotation of the drive motor 4 and the lead screw 5 is converted into the linear movement of the base 6 along the slide 3. The lighting lamp 7 is installed on the base 6 to provide illumination for the welding operation, helping the welder to clearly observe the welding part during the welding process, thereby improving the welding quality and efficiency. The control button 8 is used to control the start, stop and forward and reverse rotation of the drive motor 4, thereby realizing the adjustment and control of the position of the lighting lamp 7. The observation window 9 provides a window for the welder to observe the welding process, allowing the welder to clearly observe the welding part while protecting their face and eyes. The support plate 10 is installed on the upper edge of the welding mask 1 near the observation window 9, and a shielding plate 11 is hinged to one side of it. The shielding plate 11 can rotate flexibly around the support plate 10 to achieve the function of blocking strong light. The extension plate 12 on the shielding plate 11 increases the overall shielding range and area.

[0023] In one embodiment of this application, preferably, the base 6 has a threaded hole, and the tail end of the lighting lamp 7 is fixedly connected to a threaded rod 71. The threaded rod 71 is adapted to the threaded hole on the base 6. Slider blocks 61 are provided at both ends of the bottom of the base 6. The sliders 61 are embedded in the grooves 3 and slide in cooperation with the grooves 3. The shape of the sliders 61 matches the shape of the grooves 3. A nut is provided at the center of the bottom of the base 6, and the base 6 is threadedly connected to the lead screw 5 through the nut. The groove 3 is straight, and the base 6 slides in cooperation with the groove 3. The lead screw 5 is arranged parallel to the groove 3. In this utility model, the lighting lamp 7 and the base 6 are fixedly connected by screwing the threaded rod 71 of the lighting lamp 7 into the threaded hole of the base 6. The connection is fixed. When it is necessary to disassemble the lighting lamp 7, simply rotate the threaded rod 71 in the reverse direction to remove it from the base 6. When the drive motor 4 drives the lead screw 5 to rotate, the base 6 generates linear motion through the threaded engagement between the nut and the lead screw 5. The slider 61 slides in the slide groove 3, providing guidance for the movement of the base 6 and ensuring that the base 6 moves smoothly along the linear direction of the slide groove 3, thereby achieving precise adjustment of the position of the lighting lamp 7. At the same time, when the drive motor 4 starts, its output end drives the lead screw 5 to rotate. The lead screw 5 and the nut on the base 6 generate threaded transmission, causing the base 6 to generate linear motion along the axial direction of the lead screw 5. Since the lead screw 5 is set parallel to the slide groove 3, the base 6 moves smoothly along the slide groove 3 under the drive of the nut.

[0024] In one embodiment of this application, preferably, the shielding plate 11 and the extension plate 12 are connected by a damping hinge. The shielding plate 11 and the extension plate 12 are made of flexible plastic, and the upper surfaces of the shielding plate 11 and the extension plate 12 are provided with a reflective coating. In this utility model, when the welding worker needs to adjust the angle of the shielding plate 11, he only needs to manually apply force to make the shielding plate 11 rotate around the damping hinge. During the rotation, the damping torque generated by the damping hinge can keep the shielding plate 11 at the adjusted angle after the hand is released, thereby meeting the light-shielding requirements under different welding positions and observation needs. During the welding process, the reflective coating of the shielding plate 11 and the extension plate 12 can reflect the strong light generated during welding, preventing the strong light from directly shining on the welding worker's face and eyes, thus protecting eyesight. At the same time, the flexible plastic material allows the shielding plate 11 and the extension plate 12 to adapt to different welding postures and operating spaces, and will not be damaged by collision or squeezing.

[0025] In one embodiment of this application, preferably, a power interface is also provided on the side of the welding mask 1. The power interface is electrically connected to the drive motor 4 and the lighting lamp 7 via wires. The power interface is used to connect an external power source to supply power to the drive motor 4 and the lighting lamp 7. The drive motor 4 is a DC motor. The drive motor 4 is electrically connected to a control button 8 via wires. The control button 8 is used to control the start, stop, and forward / reverse rotation of the drive motor 4. In this utility model, when in use, an external power source is connected to the power interface on the side of the welding mask 1. The power is transmitted to the drive motor 4 and the lighting lamp 7 via wires, providing them with the required electrical energy. In this way, the drive motor 4 can work normally, realizing the power supply to the lighting lamp 7. The position can be adjusted; the lighting lamp 7 can also obtain a stable power supply to provide sufficient lighting for welding operations; when the welder issues a control command through the control button 8, the DC motor starts or stops according to the command, the circuit inside the control button 8 is connected or disconnected, generating corresponding electrical signals. These electrical signals are transmitted to the drive motor 4 through wires to control the motor's start, stop, forward and reverse rotation. When the "start" button is pressed, the drive motor 4 starts to rotate; when the "stop" button is pressed, the motor stops rotating; when the "forward" or "reverse" button is pressed, the motor rotates in the corresponding direction, thereby driving the lead screw 5 to rotate, causing the base 6 to move along the slide groove 3, thus realizing the adjustment of the position of the lighting lamp 7.

[0026] In use, this utility model features a lighting lamp 7 installed at the top of the welding mask 1. The position of the lighting lamp 7 can be flexibly adjusted by the combined use of the drive motor 4, lead screw 5, and slide 3 to meet the lighting needs of different welding scenarios. Meanwhile, a shielding plate 11 with a reflective coating and an extension plate 12 are provided along the upper edge of the observation window 9 and connected by a damping hinge to effectively block strong light and provide comprehensive facial protection.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
