[0002] As is well known, in existing welding operations, welding helmets are an important piece of personal protective equipment, mainly used to protect welders' eyes and faces from strong light, ultraviolet rays and spatter. However, traditional welding helmets use fixed filters, which cannot be quickly adjusted according to the environment, affecting work efficiency and safety.
[0003] Specifically, traditional welding caps typically use fixed filters with a fixed light transmittance, which cannot be quickly adjusted according to the welding environment or operational requirements. Furthermore, when replacing the filter, traditional welding caps require manual disassembly and installation of the filter assembly, which is not only time-consuming and labor-intensive, but also cumbersome and prone to damaging the filter, affecting efficiency and safety.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4A convenient, multi-functional welding cap for changing welding plates includes a cap shell 1, a fixing frame 4, and a changing device. The cap shell 1 has an opening at its front end, and the fixing frame 4 is located within and fitted to the opening. The changing device is located within the fixing frame 4 and includes a damping slide 16, a damping slider 17, and a filter 5. The damping slide 16 is symmetrically arranged at both ends of the fixing frame 4. The damping slider 17 passes through the damping slide 16 and is slidably connected to it. The filter 5 is located between two damping sliders 17, and a silicone groove is provided within each damping slider 17. The filter 5 is fitted to the silicone groove. The upper side wall of the fixing frame 4 has multiple openings adapted to the filter 5 and the damping slider 17. Multiple locking boxes 6 are provided at the upper end of one side wall of the fixing frame 4. Each locking box 6 contains a rotating rod 18, an auxiliary block 19, and a locking block 20. The rotating rod 18 passes through... A rotating motor 7 is installed on one side wall of the locking box 6. One end of the rotating rod 18 is connected to the output end of the rotating motor 7. An auxiliary block 19 is threaded onto the rotating rod 18. A locking block 20 is installed at one end of the auxiliary block 19 and passes through the side wall of the fixing frame 4. A fixing hole is provided at the upper end of the side wall of the damping slide 16. A limit hole is provided at the upper end of the side wall of the damping slider 17. The fixing hole coincides with the limit hole. The locking block 20 passes through the fixing hole and the limit hole and is slidably connected to them. A jog switch 8 is provided on one side of the rotating motor 7. The electric switch is signal-connected to the rotating motor 7. A small photovoltaic panel 9 is provided on the upper side of the cap 1. A battery compartment is provided at the rear end of the photovoltaic panel 9. The battery compartment is connected to the photovoltaic panel 9 and the aforementioned motor. A pull block 10 is provided on the upper end of the front side wall of the filter plate.
[0025] During use, when the user needs to replace the filter 5, they only need to lightly press the jog switch 8. After receiving the user's pressing signal, the internal circuit of the jog switch 8 closes, forming a complete current path. This closing action immediately sends a start signal to the rotating motor 7. This signal is transmitted to the control unit of the rotating motor 7 through the circuit. After receiving the start signal, the control unit energizes the coil of the rotating motor 7, and the motor starts to run. The rotation of the motor is transmitted to the rotating rod 18 connected to it through its output shaft, thereby driving the rotating rod 18 to start rotating. Since the rotating rod 18 is threadedly connected to the auxiliary block 19, the auxiliary block 19 moves with the rotation of the rotating rod 18, driving the locking block 20 to move, so that the locking block 20 disengages from the fixing hole and the limiting hole. At this time, the user can pull the pulling block 10 to slide the damping slider 17 out of the damping slide rail 16. The old filter 5 is then released along with the damping slider 17. 7 is removed together, and then the old filter 5 is pulled out of the silicone groove. The new filter 5 is inserted into the silicone groove. The elasticity of the silicone material can firmly fix the filter 5. After the replacement is completed, the damping slider 17 is passed through the damping slide 16 again so that the fixing hole and the limiting hole are aligned. The jog switch 8 is activated, and the rotating motor 7 rotates in reverse, driving the rotating rod 18 and the auxiliary block 19 back to their original positions. The locking block 20 will re-insert into the fixing hole and the limiting hole to achieve a stable lock of the filter 5. At this time, the filter 5 is firmly installed in the welding cap and can be used normally. Since the device is equipped with multiple sets of damping slides 16, the user can install multiple sets of filters 5 or protective plates according to actual needs. For example, in different welding environments, filters 5 with different light-shielding levels can be selected, or protective plates can be stacked as needed to enhance the protective effect. This flexible configuration allows the welding cap to adapt to various welding scenarios and meet different operational needs.
[0026] In practical use, it is necessary to effectively block ultraviolet rays, infrared rays and strong light generated during the welding process, provide comprehensive eye protection, and reduce damage to the welder's vision. In order to meet the above requirements, in this embodiment, the filter 5 is multi-layered, including an anti-ultraviolet layer, an anti-infrared layer and an anti-glare layer.
[0027] In practical use, it is necessary to be able to flexibly adjust the lighting range according to the work requirements and improve the visibility of the welding area. In order to meet the above requirements, in this embodiment, a support frame 11 is provided on the upper side wall of the cap shell 1, and a control plate 14 is provided at both ends of the bottom wall of the support frame 11. An adjusting rod 15 is provided between the two control plates 14. A lighting lamp 12 is provided at one end of the adjusting rod 15. A turning block 13 is provided on the outer side wall of one of the control plates 14. The adjusting rod 15 passes through the control plate 14 and is connected to the turning block 13. The adjusting rod 15 is connected to the control plate 14 with damping rotation. When the turning block 13 is turned forcefully, the adjusting rod 15 drives the lighting lamp 12 to rotate accordingly, which can adjust the orientation of the lighting lamp 12.
[0028] In actual use, it is necessary to further prevent dust and splashes. In order to meet the above requirements, in this embodiment, a protective plate 2 is provided at the rear end of the upper side wall of the cap shell 1.
[0029] In actual use, it needs to be able to adapt to users with different head circumferences and be more secure and comfortable to wear. In order to meet the above requirements, in this embodiment, the rear end of the cap shell 1 is provided with an elastic band 3.
[0030] In practical use, it is necessary to reduce the overall weight of the welding helmet, reduce the burden on the wearer's neck, and improve work concentration and safety. In order to meet the above requirements, in this embodiment, the helmet shell 1 is made of lightweight high-temperature resistant material and coated with an anti-reflective coating.
