Description

Technical Field

[0001] This utility model belongs to the field of welding cap technology, and specifically relates to a flip-top welding cap. Background Technology

[0002] Against the backdrop of rapid industrial development, welding, as a key occupation, plays an increasingly prominent role in various industries. Welding helmets, as core personal protective equipment, are directly related to welders' eye health and work safety. In the existing technology, Chinese patent publication number "CN211095232U" discloses a novel welding helmet that corrects welders' vision through a built-in vision-adjusting device, avoiding the inconvenience of wearing glasses. However, this device still has significant drawbacks in practical applications:

[0003] On the one hand, the cost of replacing the goggles is high. The goggles are designed for a fixed, integrated installation, and the lenses are made of fragile materials. During welding, they are easily scratched or broken due to spatter, impacts, and other factors. Since the goggles cannot be removed and replaced individually, the entire welding cap must be replaced if damaged, significantly increasing operating costs. This design is particularly inefficient and impractical in high-frequency operations or complex environments. On the other hand, cleaning is inconvenient. Existing welding caps lack dedicated cleaning mechanisms. When dust, slag, or spatter adheres to the goggle surface, welders must remove the welding cap or manually wipe it with a paper towel, which is inconvenient. The process is tedious and disruptive to work continuity. In dusty factory workshops or welding areas, frequent contamination of safety goggles can lead to blurred vision, reducing work efficiency and potentially causing safety hazards due to poor visibility. Furthermore, improper force during manual cleaning can further scratch the goggle lenses, accelerating equipment wear and tear. With the increasing demands for industrial automation and precision, the lack of replaceable and self-cleaning functions in existing welding helmets makes it difficult to meet the demands of modern welding operations for efficiency, safety, and cost control. It is evident that existing technology has certain defects and shortcomings, thus requiring improved design. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a flip-top welding cap to solve the problem that the overall disassembly and maintenance of goggle lenses is cumbersome and inconvenient during the application of the prior art, resulting in high overall application costs.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A flip-top welding cap includes a welding cap body. Fixing blocks are fixedly connected to the lower ends of both sides of the welding cap body. An elastic strap is fixedly connected to the bottom of each fixing block. A rotating mechanism is fixedly installed on the front of the welding cap body. A mounting frame is fixedly installed at the bottom of the rotating mechanism. A limiting mechanism is fixedly installed on the upper end of one side of the mounting frame. A safety goggle lens is movably installed inside the mounting frame. The end of the limiting mechanism passes through the mounting frame and engages with the safety goggle lens. A cleaning mechanism is fixedly installed on the upper front of the mounting frame. A housing is fixedly connected to the upper ends of both sides of the welding cap body. A storage battery is installed inside the housing.

[0007] The rotating mechanism includes a hinge seat, which is fixedly installed on the upper front of the welding cap body. A rotating shaft is rotatably connected to the inner side of the hinge seat. A mounting bracket is fixedly installed on the bottom of the rotating shaft. A first motor is fixedly installed on one side of the mounting bracket. The output end of the first motor is connected to one end of the rotating shaft.

[0008] As a preferred technical solution, the mounting bracket has sliding grooves on both sides inside, and a sliding strip is slidably connected inside the sliding groove. The inner side of the sliding strip is fixedly connected to both sides of the goggle lens.

[0009] As a preferred technical solution, a limiting hole is provided at the upper outer side of one of the slide bars, and the end of the limiting mechanism is inserted into the limiting hole through the mounting bracket.

[0010] As a preferred technical solution, the limiting mechanism includes a rail frame, which is fixedly connected to the upper end of one side of the mounting frame. A limiting spring is fixedly connected inside the rail frame, and a slider is fixedly connected to the end of the limiting spring. A side plate is fixedly installed on the outer end of the slider, and a limiting pin is fixedly connected to the lower inner end of the side plate. The limiting pin passes through the mounting frame and is inserted into the limiting hole.

[0011] As a preferred technical solution, a bridge-type handrail is fixedly connected to the outer side of the side plate, and an anti-slip handrail is fixedly connected to the outer surface of the bridge-type handrail.

[0012] As a preferred technical solution, the cleaning mechanism includes a mounting slot, which is located at the upper front of the mounting frame. A second motor is fixedly connected inside the mounting slot, and a cleaning plate is fixedly connected to the output end of the second motor. A cleaning scraper is fixedly connected to the side of the cleaning plate near the goggle lens, and the cleaning scraper is a silicone scraper.

[0013] As a preferred technical solution, a connecting rod is fixedly connected to the front of the rotating shaft. The connecting rod is inclined downwards as a whole, and a lighting lamp is fixedly connected to the outer end of the connecting rod. The lighting lamp is also inclined.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the cleaning mechanism of this flip-top welding cap is driven by a second motor in the mounting slot. When the goggles are stained, the motor is started to rotate the cleaning plate, which causes the silicone cleaning scraper to clean the surface of the goggles back and forth. The silicone scraper is soft and elastic, which can effectively clean the dirt without damaging the goggles. At the same time, when the rotating shaft drives the goggles to close, the tilted light provides auxiliary lighting to compensate for insufficient ambient light. This design eliminates the need for manual cleaning, and each cleaning takes only 5-10 seconds, improving efficiency. The lighting function reduces welding shadows and is suitable for dim or deep cavity scenes.

[0016] Secondly, the modular and flexible snap-fit ​​design of the welding helmet goggles further improves the ease of disassembly and maintenance. When it is necessary to replace the goggle lens, the old goggle lens can be removed and the new goggle lens can be inserted by pulling out the bridge-type handrail and moving the side plate to disengage the limiting pin from the limiting hole. The slide bar can then slide along the slide groove. After releasing the handrail, the limiting pin will reset and lock. No tools are required throughout the process, and the replacement cost is reduced by more than 80% compared to the traditional method. In addition, the first motor drives the rotating shaft to rotate, causing the goggle lens to flip. It hangs down for protection during welding and is lifted up for ventilation when not welding, reducing wear and improving flexibility and comfort. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 5 This embodiment of a flip-top welding cap includes a welding cap body 1. Fixing blocks 2 are fixedly connected to the lower ends of both sides of the welding cap body 1. An elastic strap 3 is fixedly connected to the bottom of the fixing blocks 2. A rotating mechanism 6 is fixedly installed on the front of the welding cap body 1. A mounting frame 4 is fixedly installed at the bottom of the rotating mechanism 6. A limiting mechanism 7 is fixedly installed on the upper end of one side of the mounting frame 4. A goggle lens 5 is movably installed inside the mounting frame 4. The end of the limiting mechanism 7 passes through the mounting frame 4 and engages with the goggle lens 5. A cleaning mechanism 8 is fixedly installed on the upper end of the front of the mounting frame 4. A housing 9 is fixedly connected to the upper ends of both sides of the welding cap body 1. A storage battery is installed inside the housing 9.

[0025] The rotating mechanism 6 includes a hinge seat 61, which is fixedly installed on the upper front of the welding cap body 1. A rotating shaft 62 is rotatably connected to the inner side of the hinge seat 61. A mounting bracket 4 is fixedly installed on the bottom of the rotating shaft 62. A first motor 63 is fixedly installed on one side of the mounting bracket 4. The output end of the first motor 63 is connected to one end of the rotating shaft 62. When this flip-top welding cap is working, the welding cap body 1 is worn on the head by the elastic straps 3 of the two side fixing blocks 2. The battery powers the device. In the rotating mechanism 6 on the front, the hinge seat 61 is fixed to the welding cap body 1, and the rotating shaft 62 is hinged to the inner side of the hinge seat 61 and connected to the mounting bracket 4. The machine 63 drives the rotating shaft 62 to rotate, thereby causing the mounting bracket 4 and the goggle lens 5 to flip, realizing the closed protection and lifting operation of the goggle lens 5. When welding, the goggle lens 5 hangs down to cover the face, and when not welding, it flips up to expose the face. The mounting bracket 4 is fixed to the goggle lens 5 by a limiting mechanism 7. The end of the limiting mechanism 7 passes through the mounting bracket 4 and is inserted into the goggle lens 5 locking structure to ensure that the goggle lens 5 is stably installed. The cleaning mechanism 8 can automatically clean the surface of the goggle lens 5. The overall structure is driven by a motor to realize the flexible flipping of the goggle, meeting the need for convenient switching between protection and operation in welding operations.

[0026] refer to Figures 1-3 and Figure 5The mounting bracket 4 has sliding grooves 10 on both sides inside, and slide bars 11 are slidably connected inside the sliding grooves 10. The inner side of the slide bars 11 is fixedly connected to both sides of the goggle lens 5. A limit hole 12 is opened at the upper outer side of one slide bar 11. The end of the limit mechanism 7 passes through the mounting bracket 4 and is inserted into the limit hole 12. The limit mechanism 7 includes a rail frame 71, which is fixedly connected to the upper side of one side of the mounting bracket 4. A limit spring 72 is fixedly connected inside the rail frame 71, and the end of the limit spring 72 is fixedly connected to... A slider 73 is attached, and a side plate 74 is fixedly installed on the outer end of the slider 73. A limit pin 75 is fixedly connected to the lower inner end of the side plate 74. The limit pin 75 passes through the mounting frame 4 and is inserted into the limit hole 12. A bridge-type handrail 76 is fixedly connected to the outer side of the side plate 74. An anti-slip handrail glove is fixedly connected to the outer surface of the bridge-type handrail 76. During the application of this device, the sliding grooves 10 on both sides inside the mounting frame 4 and the sliding strips 11 form a sliding guide structure. The goggle lens 5 is fixed to the mounting frame 4 through the sliding strips 11 and can slide along the slide. The groove 10 moves laterally, and the limiting mechanism 7 is fixed to the outside of the mounting frame 4 via the rail frame 71. The limiting spring 72 inside the rail frame 71 abuts against the slider 73. The side plate 74 at the outer end of the slider 73 is connected to the bridge-type handrail 76. The inner limiting pin 75 passes through the mounting frame 4 and inserts into the limiting hole 12 of the slide bar 11 to lock the goggle lens 5. When replacing the goggle lens 5, the operator holds the anti-slip handrail and pulls the bridge-type handrail 76 outward, causing the side plate 74 to move outward against the elastic force of the limiting spring 72, so that the limiting pin 75 disengages. After the limiting hole 12 and the slider 11 are unrestrained, they can slide freely along the slide groove 10, thereby pulling out the old goggle lens 5. After inserting the new goggle lens 5, the handle is released, the limiting spring 72 returns to its original position and pushes the slider 73 to move inward. The limiting pin 75 is then re-engaged in the limiting hole 12 of the slider 11 of the new goggle lens 5, completing the quick fixation. This structure achieves convenient installation and removal of the goggle lens 5 through the spring force and sliding cooperation. It can be operated without tools, improving maintenance efficiency while ensuring the stability of the goggle lens 5 installation.

[0027] refer to Figures 1-4The cleaning mechanism 8 includes a mounting slot 81 located at the upper front of the mounting frame 4. A second motor 82 is fixedly connected inside the mounting slot 81. A cleaning plate 83 is fixedly connected to the output end of the second motor 82. A cleaning scraper 84 is fixedly connected to the side of the cleaning plate 83 near the goggle lens 5. The cleaning scraper 84 is a silicone scraper. A connecting rod 85 is fixedly connected to the front of the rotating shaft 62. The connecting rod 85 is inclined downwards. A light 86 is fixedly connected to the outer end of the connecting rod 85. The light 86 is also inclined. During use, the second motor 82 of the cleaning mechanism 8 is fixed in the mounting slot 81 at the upper front of the mounting frame 4, and its output end drives the cleaning plate 83. 3. Rotation causes the silicone cleaning scraper 84 fixed on the cleaning plate 83 to rotate synchronously, performing circumferential scraping cleaning on the surface of the goggle lens 5. The silicone material ensures effective cleaning while avoiding scratches on the goggle lens 5. When the rotating shaft 62 drives the goggle lens 5 to close, the connecting rod 85, which is tilted on the front, rotates synchronously, causing the outer end lighting lamp 86 to adjust with the position of the goggle lens 5. The tilt angle of the lighting lamp 86 ensures that the light is focused on the welding area, compensating for insufficient ambient light. This design eliminates the need for manual operation by the welder, achieving linkage between cleaning and lighting functions through motor drive. The cleaning process is fast and efficient, and the lighting angle is dynamically adjusted with the goggle, significantly improving the visibility and convenience of welding operations.

[0028] Operating principle and advantages: The cleaning mechanism 8 of this flip-top welding cap is driven by the second motor 82 in the mounting slot 81 to achieve efficient cleaning function, facilitating quick cleaning operations. During use, when dust, welding slag, or spatter adheres to the surface of the goggle lens 5, the operator starts the second motor 82, whose output end drives the cleaning plate 83 to rotate, causing the silicone cleaning scraper 84 fixed on the cleaning plate 83 to rotate synchronously, reciprocatingly scraping and cleaning the surface of the goggle lens 5. The silicone scraper is soft and elastic, effectively removing stubborn stains while avoiding scratching the goggle lens 5. At the same time, when the rotating shaft 62 drives the goggle lens 5 to close during use, its tilted lighting lamp 86 can provide auxiliary lighting, thereby compensating for insufficient ambient light. This design eliminates the need for welders to manually remove the welding cap or use cleaning tools, and a single cleaning process only takes 5-10 seconds, significantly improving work efficiency. The lighting function can also reduce welding shadows and improve operational accuracy, making it especially suitable for dimly lit or deep cavity welding scenarios.

[0029] During the application of this welding helmet, the safety goggle lens 5 adopts a modular design with elastic snap-fit, facilitating quick and easy maintenance and replacement. When replacing the goggle lens, the operator pulls outwards on the bridge-type handle 76, causing the side plate 74 to move outwards against the elastic force of the limiting spring 72. This disengages the limiting pin 75 from the limiting hole 12 of the slide bar 11, releasing the lock on the safety goggle lens 5. At this time, the slide bars 11 on both sides of the safety goggle lens 5 can slide freely along the sliding groove 10 inside the mounting bracket 4, easily pulling out the old safety goggle lens 5 and inserting the new one. Then, the bridge-type handle 76 is released, and the limiting spring... Spring 72 resets and pushes the limit pin 75 to re-engage into the limit hole 12, completing the fixation. The entire replacement process requires no tools, reducing costs by more than 80% compared to the traditional method of replacing the entire welding cap. In addition, the first motor 63 drives the rotating shaft 62 inside the hinge seat 61 to rotate, causing the mounting bracket 4 and the goggle lens 5 to flip as a whole. During welding, the goggle lens 5 is in a drooping state to provide protection; in the non-welding state, the goggle lens 5 can be quickly lifted by the flipping mechanism, which facilitates ventilation, communication or posture adjustment for welders, reduces unnecessary wear on the goggle lens 5, and improves the flexibility and comfort of use.
