Description

Technical Field

[0001] This utility model relates to a welding mask, and more particularly to a portable steel structure welding mask applied in the field of welding auxiliary tools. Background Technology

[0002] With the rapid development of industrial manufacturing, especially in the fields of automobiles, machinery, and aerospace, the demand for welding operations has increased, driving the growth of the market for welding protective masks. Welding masks are being used more and more widely in welding operations, and welders' requirements for safety, efficiency, and comfort are constantly rising. Research on welding masks has been developing in the direction of adapting to more complex working environments.

[0003] Patent CN208876980U discloses a welding protective mask for metalworking practice, including a mask body, a hat-type fixing frame on the upper part of the mask body, side guards slidingly provided on both sides of the mask body, and a flexible neck protection component on the lower part of the mask body; the mask body has two observation ports, each with a light-shielding plate, and a light-blocking plate on the outer surface of the mask body located in front of the two observation ports; a support pad is provided on the inner surface of the mask body, located between the two observation ports, and an elastic pad layer is provided on the outer surface of the support pad.

[0004] During the welding process, the light-blocking plate of this welding protective mask is easily contaminated, causing blurred vision and affecting welding accuracy and safety. The light-blocking plate will darken due to damage during welding. The design that is not easy to replace will reduce work efficiency and shorten service life. The top of the hat-style fixing frame lacks a good adjustment system, affecting the protective effect and comfort. Wearing the mask for welding steel structures in high-temperature environments for a long time will cause stuffiness. It also has poor sound conduction and is not convenient. Summary of the Invention

[0005] The technical problems to be solved by this utility model in view of the above-mentioned prior art are: the light shield is easily contaminated, which leads to blurred vision and thus affects the welding accuracy and safety; the light shield will darken due to damage to the light shield during the welding process; the design that is not easy to replace will reduce work efficiency and shorten service life; the top of the hat-type fixing frame lacks a good adjustment system, which affects the protective effect and comfort; wearing the mask for welding steel structures for a long time in high temperature environment will cause stuffiness; the sound conduction is poor and it is not convenient.

[0006] To solve the above problems, this utility model provides a portable steel structure welding mask, including a mask body and a light-transmitting lens. The light-transmitting lens is disposed on the mask body, and an adjuster is installed on the light-transmitting lens. A dual-axis drive motor is installed inside the adjuster, and a start button electrically connected to the dual-axis drive motor is installed on the adjuster. The two output ends of the dual-axis drive motor are respectively connected to a threaded rod and a drive gear plate.

[0007] The lens has a hollow structure and a sliding groove inside. A replacement piece is slidably connected inside the sliding groove. The top of the replacement piece has a threaded structure that mates with a threaded rod. The adjuster has multiple drive pieces that mate with the teeth of the drive gear. Each drive piece has a sliding groove at the end away from the drive gear. The drive piece is rotatably connected to the adjuster via a fixing rod near the sliding groove. An adjustment knob is inserted into one side of the adjuster. A drive rod that mates with the sliding groove on the drive piece is connected to the outer ring of the adjustment knob. An elastic pad is installed inside the lens.

[0008] In the aforementioned portable steel structure welding mask, pressing the start button and rotating the adjustment knob connected to one side of the adjuster controls the drive rod connected to it to move the drive plate. The dual-axis drive motor drives the threaded rod to rotate, and the replacement piece that cooperates with the threaded rod slides in the sliding groove and pushes off the light-transmitting lens placed in the light-transmitting lens. The elastic soft pad squeezes the multiple light-transmitting lenses in the light-transmitting lens so that they are stretched and not easily shifted, making the structure more stable.

[0009] As a further improvement of this application, the drive plate has a two-section structure. One end of the drive plate is engaged with the teeth of the drive gear disk, and the other end of the drive plate is controlled by the drive rod to rotate with the fixed rod. The drive plate is made of high-strength elastic material.

[0010] As a further improvement of this application, the mask body is designed with a double-layer structure. Opening and closing doors and film removal holes are installed on both sides of the light-transmitting lens. A fixing cover is provided on the top of the mask body. Multiple protective straps are connected to the fixing cover. The protective straps are connected by a fixing knob. The protective straps are made of soft elastic material.

[0011] As a further improvement of this application, multiple breathing valves are installed on the mask body, and the breathing valves penetrate into the interior of the mask body.

[0012] As another improvement of this application, the inner side of the mask body is coated with an anti-fog coating, and the outer side of the mask body is made of steel structure.

[0013] As a further improvement to this application, a nose pad is installed on the inner side of the mask body, and the nose pad is made of an elastic soft adhesive material.

[0014] In summary, during normal welding, sparks can easily damage the mask body and the lens. Therefore, in the event of lens damage, pressing the start button and rotating the adjustment knob connected to one side of the adjuster controls the drive rod connected to it to move the drive plate. This releases the limiting force on the drive gear plate, causing the dual-axis drive motor to rotate the threaded rod. The replacement plate, which cooperates with the threaded rod, slides in the sliding groove and pushes off the lens placed inside the lens. Before use, multiple lenses are installed in the lens. The elastic pads installed inside the lens compress the lenses, making them less prone to shifting under tension. This results in a more stable structure, improves work efficiency, greatly enhances the protective effect, and increases the service life of the welding mask. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-6 A portable steel structure welding mask is shown, including a mask body 1 and a light-transmitting lens 2. The light-transmitting lens 2 is disposed on the mask body 1. An adjuster 201 is installed on the light-transmitting lens 2. A dual-axis drive motor 202 is installed in the adjuster 201. A start button 211 electrically connected to the dual-axis drive motor 202 is installed on the adjuster 201. The start button 211 is used to control the dual-axis drive motor 202. The two output ends of the dual-axis drive motor 202 are respectively connected to a threaded rod 203 and a drive gear 204.

[0026] The light-transmitting lens 2 has a hollow structure and a sliding groove inside. A replacement piece 205 is slidably connected within the sliding groove. The top of the replacement piece 205 has a threaded structure that mates with the threaded rod 203. The threaded rod 203 is driven by the dual-axis drive motor 202, which in turn drives the replacement piece 205 to move horizontally within the sliding groove. The adjuster 201 has multiple drive pieces 206 that mate with the teeth of the drive gear disk 204. The drive pieces 206 and the teeth of the drive gear disk 204 interlock, restricting the rotation of the threaded rod 203 driven by the dual-axis drive motor 202. Each drive piece 206 has a sliding groove at the end away from the drive gear disk 204. The drive piece 206 near the sliding groove has a sliding groove. The fixed rod 207 is rotatably connected to the adjuster 201. The fixed rod 207 rotatably fixes the drive plate 206 on the adjuster 201. An adjustment knob 208 is inserted into one side of the adjuster 201. A drive rod 209 that cooperates with the sliding groove on the drive plate 206 is connected to the outer ring of the adjustment knob 208. By turning the adjustment knob 208, the drive rod 209 connected to its outer ring slides in the sliding groove on the drive plate 206, so that the drive plate 206 is disengaged from the drive gear 204, thereby releasing the limiting force of the drive plate 206 on the drive gear 204. An elastic soft pad 210 is installed inside the light-transmitting lens 2. The elastic soft pad 210 presses the light-transmitting lens so that it is stretched and does not easily shift.

[0027] Please see Figure 5 The drive plate 206 has a two-section structure. One end of the drive plate 206 engages with the teeth of the drive gear 204, making the structure more robust. The other end of the drive plate 206 is controlled by the drive rod 209 to rotate with the fixed rod 207. The drive plate 206 is made of high-strength elastic material, which is strong and not easily damaged, and highly elastic and not easily deformed and unable to recover.

[0028] Please see Figure 2 and Figure 6The mask body 1 is designed with a double-layer structure, which can form a heat insulation layer to reduce the temperature difference between the inside and outside. The light-transmitting lens 2 is equipped with an opening and closing door 101 and a lens removal hole on both sides. The light-transmitting lens is inserted into the light-transmitting lens 2 through the opening and closing door 101, and the lens removal hole is used to eject the damaged light-transmitting lens. The top of the mask body 1 is provided with a fixing cover 102 for fixing the welding mask. Multiple protective straps 103 are connected to the fixing cover 102. The protective straps 103 are connected by a fixing knob 104. The protective straps 103 are made of soft elastic material. The distance between the protective straps 103 can be adjusted by the fixing knob 104 to improve the wearing comfort and relieve the fatigue of wearing for a long time.

[0029] In summary, during normal welding, sparks can easily damage the mask body 1 and the light-transmitting lens. Therefore, when the light-transmitting lens is damaged, by rotating the adjustment knob 208 connected to one side of the adjuster 201, the drive rod 209 connected to it slides in the sliding groove on the drive plate 206. This causes the drive plate 206, which is normally jammed with the teeth of the drive gear 204, to disengage from the drive gear 204, thus releasing the limiting force of the drive plate 206 on the drive gear 204. Pressing the start button 211 controls the dual-axis drive motor 202 to drive the threaded rod 203 to rotate. The replacement piece 205, which cooperates with the threaded rod 203, slides in the sliding groove and pushes out the damaged light-transmitting lens from the pick-up hole and into the light-transmitting lens 2. The adjustment knob 208 is used to limit the dual-axis drive motor... The drive mechanism 202 prevents accidental triggering of the start button 211 during welding, which could cause multiple light-transmitting lenses to pop out. The drive plate 206 is made of high-strength elastic material, which is strong, not easily damaged, and highly elastic, and is not easily deformed and cannot be restored. Before use, the multiple light-transmitting lenses are inserted into the light-transmitting mirror 2 through the opening and closing doors 101 installed on both sides of the light-transmitting mirror 2. The elastic soft pads 210 installed inside the light-transmitting mirror 2 compress the light-transmitting lenses, making them stretch and not easy to shift, resulting in a more stable structure. This improves work efficiency and greatly enhances the protective effect, increasing the service life of the welding mask. The double-layer structure of the mask body 1 can form a heat insulation layer to reduce the temperature difference between the inside and outside. The multiple protective straps 103 connected to the fixed cover 102 on the top are adjusted for tightness by the fixed knob 104, improving wearing comfort and relieving fatigue from wearing for a long time.

[0030] Second implementation method:

[0031] Figure 1 and Figure 6 A portable steel structure welding mask is shown. Unlike the first embodiment, the mask body 1 is equipped with multiple breathing valves 105. The breathing valves 105 penetrate into the inside of the mask body 1. The breathing valves 105 ensure that external air can enter, while the exhaled moisture can also be effectively discharged, relieving the stuffiness caused by wearing the welding mask for a long time.

[0032] Please see Figure 6 The inner side of the mask body 1 is coated with an anti-fog coating. The anti-fog coating prevents water vapor from condensing into small water droplets without affecting sound transmission, thus maintaining clear vision. The outer side of the mask body 1 is made of steel structure. The steel structure material has high strength, making the welded mask less prone to damage and providing high protection. The inner side of the mask body 1 is equipped with a nose pad 106. The nose pad 106 is made of elastic soft adhesive material. The nose pad 106 increases the sealing of the mouth of the welded mask, reducing the chance of humid and hot air escaping from breathing coming into contact with the light-transmitting lens. In addition, the elastic soft adhesive material improves the wearing comfort.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
