Description

Technical Field

[0001] This utility model belongs to the field of welding eyewear technology, and specifically relates to a portable automatic optical variable glasses for welding. Background Technology

[0002] Welding goggles are specialized protective equipment used in welding operations to protect the eyes. Their core function is to block harmful rays such as strong light, ultraviolet rays, and infrared rays generated during welding, preventing burns or damage to the eyes. The lenses are usually specially coated to effectively filter specific wavelengths of light. Depending on the type of welding, the lens transmittance and protection level have corresponding standards to adapt to various working conditions such as argon arc welding, electric arc welding, and gas welding. Welding goggles are essential occupational protective equipment for welders; proper selection and use can significantly reduce the risk of occupational eye injuries.

[0003] Currently, the lenses of commercially available automatic optical switching welding glasses are usually integrated with the automatic optical switching system, resulting in a relatively complex structure. When a lens malfunctions and needs replacement, not only the lens itself but also the entire automatic optical switching system must be disassembled and reassembled. This is difficult for ordinary welders and generally requires professional personnel, increasing repair and time costs. Furthermore, due to the high technical content, replacement lenses are relatively expensive, further increasing the overall cost of use. Utility Model Content

[0004] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a portable automatic light-changing glasses for welding, so as to solve the problem that the light-blocking lens of automatic light-changing welding glasses is usually integrated with the automatic light-changing system, which has a relatively complex structure. When the lens has a problem and needs to be replaced, not only the lens itself is involved, but the entire automatic light-changing system also needs to be disassembled and reassembled. This is difficult for ordinary welders to operate and generally requires professional personnel to complete, which increases the maintenance cost and time cost.

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

[0006] A portable automatic optical variable light glasses for welding includes a frame, a protective lens fixedly connected to the bottom of the frame, connecting seats rotatably connected to both ends of the frame, a support leg movably connected to one side of the connecting seat, a connecting component installed at one end of the support leg, a mounting seat movably connected to one side of the frame, a rotating shaft rotatably connected inside the mounting seat, a micro motor installed at one end of the mounting seat, the output end of the micro motor being fixedly connected to the rotating shaft, light-blocking lenses symmetrically fixedly connected to the outer wall of the rotating shaft, a control button installed at the other end of the mounting seat, and fixing components symmetrically installed on one side of the mounting seat;

[0007] The fixing assembly includes a cavity, a first return spring, a movable plate, and a locking block. Assembly blocks are symmetrically fixedly connected to one side of the mounting base. A cavity is formed inside each assembly block. A first return spring is fixedly connected to one side of the cavity, and a movable plate is fixedly connected to the other end of the first return spring. The movable plate is slidably connected to the cavity. A locking block is fixedly connected to the other side of the movable plate, with its other end extending beyond the top of the assembly block. A bevel is provided on one side of the locking block. Assembly slots are symmetrically formed on one side of the frame, and the assembly blocks are inserted into these slots. A locking groove is formed on one side of each assembly slot. The locking groove is snapped together, and an unlocking block is slidably connected inside the locking groove. The other end of the unlocking block extends out of the top of the frame. Guide blocks are fixedly connected to both sides of the unlocking block. Guide grooves are opened on both sides inside the locking groove. The guide blocks and guide grooves are slidably connected. When the shading lens is worn, scratched or aged, the damaged lens can be replaced in time without having to send the entire pair of glasses for repair or replacement, which greatly reduces repair and replacement costs. Moreover, it allows welders to change the shading lens to a suitable one at any time according to actual needs, so that the welding glasses can flexibly adapt to complex and changing working environments.

[0008] As a preferred technical solution, the fixing component includes a receiving cavity, a pressing plate, a second return spring, a pressing block, and a locking block. A fixing block is fixedly connected to one end of the support leg. Receiving cavities are symmetrically formed inside the fixing block. A second return spring is symmetrically fixedly connected to one side of each receiving cavity. A pressing plate is fixedly connected to the other end of the second return spring. The pressing plate is slidably connected to the receiving cavity. A pressing block and a locking block are fixedly connected to the other side of the pressing plate. The pressing block extends outward from the outside of the support leg, and the locking block extends outward from the outside of the fixing block. A fixing groove is formed on one side of the connecting seat. The fixing block and the fixing groove are plugged in. Locking slots are symmetrically formed inside the fixing groove, and the locking block and the locking slots are slidably connected. When the support leg experiences wear or breakage, the user can easily disassemble and assemble it by hand without the need for screwdrivers or other tools. This allows for quick and easy disassembly and assembly, even for first-time users. This greatly improves installation efficiency, avoids wasted time due to complex installation procedures, and significantly reduces maintenance costs.

[0009] As a preferred technical solution, a positioning block is fixedly connected to one side of the mounting base, and a positioning groove is opened on one side of the lens frame. The positioning block and the positioning groove are plugged in, which can make the installation of the light-blocking lens accurate, ensure the integrity and effectiveness of the protective function, and provide reliable safety protection for users.

[0010] In summary, the present invention has the following main advantages:

[0011] First, in this utility model, the mounting base, along with the light-shielding lens, is combined with one side of the frame, allowing the assembly block to be inserted into the assembly groove. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block, causing the locking block to drive the moving plate to press against the first return spring. The first return spring is compressed, and at the same time, the locking block retracts into the cavity. When the locking block moves to the locking groove, the first return spring resets, and the locking block pops out and engages with the locking groove to fix it, thus completing the installation of the light-shielding lens. When the light-shielding lens is worn, scratched, or aged, the damaged lens can be replaced in time without having to send the entire pair of glasses for repair or replacement, greatly reducing maintenance and replacement costs. Moreover, it allows welders to change the appropriate light-shielding lens at any time according to actual needs, enabling the welding glasses to flexibly adapt to complex and changing working environments.

[0012] Secondly, in this utility model, pressing the button causes the button plate to move the locking block. The button plate presses against the second return spring, compressing the second return spring. Simultaneously, the locking block retracts into the receiving cavity, merging the support leg with one side of the connecting seat, allowing the fixing block to be inserted into the fixing groove. Releasing the button causes the second return spring to reset, and the button plate springs back, causing the locking block to pop out. The locking block engages and fixes with the slot, completing the installation of the support leg. When the support leg experiences wear, breakage, or other problems, the user can easily disassemble and assemble it using this simple method. The entire process does not require the use of screwdrivers or other tools; the support leg can be disassembled and assembled by hand in a short time. Even first-time users can quickly master the operation method, greatly improving installation efficiency, avoiding time wastage caused by complex installation procedures, and significantly reducing maintenance costs.

The other end of the locking block 144 extends beyond the top of the assembly block 8. A slope is provided on one side of the locking block 144. Assembly grooves 9 are symmetrically formed on one side of the mirror frame 1. The assembly block 8 and... The assembly slot 9 is a plug-in type, and a locking slot 15 is provided on one side inside the assembly slot 9. The locking block 144 is snapped into the locking slot 15. The mounting base 7, together with the light-shielding lens 12, is combined with one side of the frame 1, so that the assembly block 8 is inserted into the assembly slot 9. During the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, so that the locking block 144 drives the moving plate 143 to press against the first return spring 142. The first return spring 142 is compressed, and at the same time the locking block 144 retracts into the cavity 141. When the locking block 144 moves to the locking slot 15, the first return spring 142 returns to its original position, and the locking block 144 pops out and snaps into the locking slot 15 for fixation.

[0022] refer to Figure 5 An unlocking block 16 is slidably connected inside the locking groove 15. The other end of the unlocking block 16 extends out of the top of the frame 1.

The guide blocks 18 and the guide grooves 17 are slidably connected. Pushing the unlocking block 16 causes it to slide inside the locking groove 15. At the same time, the unlocking block 16 drives the guide blocks 18 to slide inside the guide grooves 17. The unlocking block 16 pushes the locking block 144, causing the locking block 144 to drive the moving plate 143 to press against the first return spring 142. The first return spring 142 is compressed. At the same time, the locking block 144 retracts into the cavity 141, and the locking block 144 and the locking groove 15 are no longer engaged.

[0023] refer to Figures 2 to 3 The fixing assembly 14 includes a receiving cavity 191, a pressing plate 192, a second return spring 193, a pressing block 194, and a locking block 195. A fixing block 5 is fixedly connected to one end of the support leg 4. Receiving cavities 191 are symmetrically formed inside the fixing block 5. A second return spring 193 is symmetrically fixedly connected to one side of the receiving cavity 191. A pressing plate 192 is fixedly connected to the other end of the second return spring 193. The pressing plate 192 is slidably connected to the inside of the receiving cavity 191. A pressing block 194 and a locking block 195 are fixedly connected to the other side of the pressing plate 192. The other side of the pressing block 194 extends outward from the outside of the support leg 4, and the other side of the locking block 195 extends outward from the outside of the fixing block 5. A connecting seat 3 has a... There is a fixing groove 6, and the fixing block 5 is inserted into the fixing groove 6. The fixing groove 6 has symmetrical slots 20. The slot 195 is slidably connected to the slot 20. Pressing the button 194 causes the button plate 192 to move the slot 195. The button plate 192 presses against the second return spring 193, and the second return spring 193 is compressed. At the same time, the slot 195 retracts into the receiving cavity 191, merging the support leg with one side of the connecting seat 3, so that the fixing block 5 is inserted into the fixing groove 6. Releasing the button 194 causes the second return spring 193 to return to its original position. The button plate 192 rebounds and causes the slot 195 to pop out. The slot 195 is engaged and fixed with the slot 20, completing the installation of the support leg 4.

[0024] refer to Figure 2 A positioning block 21 is fixedly connected to one side of the mounting base 7, and a positioning groove 22 is opened on one side of the frame 1. The positioning block 21 and the positioning groove 22 are inserted into each other. The mounting base 7 together with the light-blocking lens 12 is merged with one side of the frame 1 so that the positioning block 21 is inserted into the positioning groove 22.

[0025] Operating principle and advantages: First, press the button 194, causing the button plate 192 to move the locking block 195. The button plate 192 presses against the second return spring 193, compressing the second return spring 193. At the same time, the locking block 195 retracts into the receiving cavity 191, merging the support leg with one side of the connecting seat 3, allowing the fixing block 5 to be inserted into the fixing groove 6. Release the button 194, the second return spring 193 returns to its original position, and the button plate 192 rebounds, causing the locking block 195 to pop out. The locking block 195 engages and fixes with the groove 20, completing the installation of the support leg 4. Then, merge the mounting seat 7 along with the light-blocking lens 12 with one side of the frame 1, allowing the assembly block 8 to be inserted into the assembly. Inside the slot 9, during the insertion process, the squeezing force applies pressure to the inclined surface of the locking block 144, causing the locking block 144 to drive the moving plate 143 to press against the first return spring 142. The first return spring 142 is compressed, and at the same time, the locking block 144 retracts into the cavity 141. When the locking block 144 moves to the locking slot 15, the first return spring 142 resets, and the locking block 144 pops out and engages with the locking slot 15. After being worn through the support legs, when performing welding operations, the control button 13 is pressed to start the micro motor 10, which controls the rotating shaft 11 to rotate the light-shielding lens 12, and the light-shielding lens 12 cooperates with the protective lens 2.

[0026] When the shading lens 12 is worn, scratched or aged, the present invention can replace the damaged lens in time without having to send the entire pair of glasses for repair or replacement, which greatly reduces the repair and replacement costs. Moreover, it allows welders to replace the shading lens 12 with a suitable one at any time according to actual needs, so that the welding glasses can flexibly adapt to complex and ever-changing working environments.
