Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an intelligent welding mask. Background Technology

[0002] A welding mask is a tool used to protect workers during welding and cutting operations. A traditional welding mask consists of an observation window, a filter, a transparent glass plate, and the mask body. The filter and transparent glass plate are overlapped and installed in the observation window. The filter primarily filters ultraviolet and infrared light to protect the eyes. The mask body protects the face from arc radiation damage.

[0003] For example, Chinese utility model patent (CN216417506U) discloses an intelligent welding mask, which states: "This utility model eliminates the repetitive removal and covering actions, improving welding efficiency." It also states: "However, the transmission welding mask has shortcomings. For example, due to the filter, the actual situation of the welding point cannot be clearly seen, requiring the mask to be removed before checking the welding point. During welding, the face is covered again with the mask, and the entire welding process requires repeated removal and covering actions, resulting in long welding processing time and low efficiency."

[0004] In summary, existing technologies utilize a first camera, a second camera, a display, a frame, a filter, a splitter, an electronic control board, a power supply, a light intensity sensor, a rubber ring, a lighting assembly, a light shield, and a device cavity to achieve intelligent imaging of the mask. However, this method has the following technical problems: In practice, some operators need to wear glasses when performing welding due to vision limitations, and wearing glasses may increase the distance between the mask and the operator's face. The aforementioned devices do not have a structure to adjust the distance between the mask and the operator's face. Therefore, this application proposes an intelligent welding mask to solve the technical problems mentioned in the above patents and provide a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide an intelligent welding mask to address the aforementioned technical problems. Pulling the connecting plate allows the T-shaped column to slide inside the housing, simultaneously causing the sliding column to slide inside the support housing. A second limiting component restricts the sliding column's movement into the support housing. Pulling the connecting plate adjusts the distance between the support frame and the mask body. The threaded rod can be rotated according to the operator's face shape, allowing the support frame to be adjusted in height under the constraints of the limiting column and connecting plate. This ensures that the operator's chin rests on the support frame when wearing the mask. Changing the distance between the connecting plate and the mask body by pulling the connecting plate changes the distance between the support frame and the mask body, thus altering the distance between the operator's face and the mask body. This allows the mask to be worn by operators wearing various types of glasses, reducing discomfort caused by the mask pressing on the eyes and improving the device's practicality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A smart welding mask used in welding.

[0008] The intelligent welding mask specifically includes:

[0009] The mask body is equipped with an intelligent protection component. A protective plate is fixedly connected to the outer wall of the mask body. An adjustable headband is rotatably connected to the inner wall of the protective plate. Straps are fixedly connected to the outer wall of the mask body near the left and right sides respectively. A support mechanism is provided on the mask body. A protection replacement mechanism is provided on the support mechanism.

[0010] The support mechanism includes a support shell, a sliding column, a connecting plate, a first limiting component, a second limiting component, and a rotating support component. The support shell is fixedly connected to the outer wall of the mask body, and the sliding column is slidably connected to the inner wall of the support shell. The connecting plate is fixedly connected to one end of the sliding column located outside the support shell.

[0011] In a preferred embodiment of the intelligent welding mask provided by this utility model, the first limiting component includes a housing. The outer wall of the mask body and the left and right sides of the supporting shell are respectively fixedly connected to the housing. The inner walls of the two housings are respectively slidably connected to T-shaped columns. The ends of the two T-shaped columns away from the mask body are fixedly connected to the outer wall of the connecting plate.

[0012] In a preferred embodiment of the intelligent welding mask provided by this utility model, the second limiting component includes ratchet teeth. Multiple ratchet teeth are fixedly connected to the outer wall of the sliding column. A rotating rod is rotatably connected to the inner wall of the support shell. A pawl adapted to the ratchet teeth is fixedly connected to the outer wall of the rotating rod. Torsion springs are respectively sleeved on the outside of the rotating rod and on both sides of the pawl. The two ends of the torsion springs are respectively fixedly connected to the outer wall of the pawl and the inner wall of the support shell.

[0013] In a preferred embodiment of the intelligent welding mask provided by this utility model, the rotating support assembly includes a threaded rod, the inner wall of the connecting plate is threadedly connected to the threaded rod, the top end of the threaded rod is rotatably connected to a support frame, and the bottom of the support frame and the left and right sides of the threaded rod are respectively fixedly connected to limiting posts, and both limiting posts are slidably connected to the inner wall of the connecting plate.

[0014] In a preferred embodiment of the intelligent welding mask provided by this utility model, the protection replacement mechanism includes a soft pad, a plug rod fixedly connected to the bottom of the soft pad, the plug rod being movably inserted into a support frame, two U-shaped frames fixedly connected to the outer wall of the support frame, and an mounting frame fixedly connected to the outer wall of the soft pad, the mounting frame being movably inserted into the two U-shaped frames.

[0015] As a preferred embodiment of the intelligent welding mask provided by this utility model, the protection replacement mechanism further includes a fixed shell and a U-shaped handle. The outer walls of the two U-shaped frames are fixedly connected to the fixed shells. The outer wall of the U-shaped handle is slidably connected to the inner wall of the two fixed shells. The two ends of the U-shaped handle pass through the two U-shaped frames and are movably inserted into the mounting frame. The outer wall of the U-shaped handle is fixedly connected to two fixed rings. The fixed rings are slidably connected to the inner wall of the fixed shell. The outside of the U-shaped handle is fitted with two springs. The two ends of the springs are respectively fixedly connected to the outer wall of the fixed ring and the inner wall of the fixed shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The intelligent welding mask provided by this utility model allows the T-shaped column to slide inside the housing by pulling the connecting plate, and simultaneously causes the sliding column to slide inside the support housing. The sliding column is restricted from sliding into the support housing by the second limiting component. Pulling the connecting plate adjusts the distance between the support frame and the mask body. The threaded rod can be rotated according to the operator's face shape, allowing the support frame to be adjusted in height under the constraint of the limiting column and connecting plate. This ensures that the operator's chin rests on the support frame when wearing the mask body. Changing the distance between the connecting plate and the mask body by pulling the connecting plate changes the distance between the support frame and the mask body, thus changing the distance between the operator's face and the mask body. This allows the device to accommodate operators wearing various types of glasses, reducing discomfort caused by the mask body pressing on the eyes and improving the device's practicality.

[0018] The intelligent welding mask provided by this utility model allows the U-shaped handle to slide relative to the two fixed shells by pulling it, thereby removing the U-shaped handle from the mounting frame and releasing the restriction on the soft pad. The operator can then pull the mounting frame out of the U-shaped frame and the insertion rod out of the support frame. The soft pad can then be rinsed. The soft pad is more comfortable than the operator's chin resting directly on the support frame. Furthermore, the soft pad can be easily removed for cleaning, reducing the possibility of odor caused by sweat accumulation on the soft pad, which would otherwise reduce the operator's user experience.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background art, however, some operators need to wear glasses when performing electric welding due to vision problems. Wearing glasses may increase the distance between the mask and the operator's face. However, the above-mentioned device does not have a structure for adjusting the distance between the mask and the operator's face.

[0030] To solve this technical problem, this utility model provides an intelligent welding mask that is applied to welding.

[0031] For details, please refer to Figures 1-2 The intelligent welding mask specifically includes:

[0032] The mask body 1 has an intelligent protection component 2 installed on it. A protective plate 3 is fixedly connected to the outer wall of the mask body 1. An adjustable headband 4 is rotatably connected to the inner wall of the protective plate 3. Straps 5 are fixedly connected to the outer wall of the mask body 1 near the left and right sides respectively. A support mechanism 6 is provided on the mask body 1. A protection replacement mechanism 7 is provided on the support mechanism 6.

[0033] The support mechanism 6 includes a support shell 8, a sliding column 9, a connecting plate 10, a first limiting component, a second limiting component, and a rotating support component. The support shell 8 is fixedly connected to the outer wall of the mask body 1, and the sliding column 9 is slidably connected to the inner wall of the support shell 8. The connecting plate 10 is fixedly connected to one end of the sliding column 9 located outside the support shell 8.

[0034] The intelligent protection component 2 in this application has the same specific structure and working principle as the mechanism in the prior art mentioned in the background, which consists of a first camera, a second camera, a display, a frame, a filter, a split screen, an electronic control board, a power supply, a light intensity sensor, a rubber ring, a lighting assembly, a light shield, and an equipment cavity.

[0035] The intelligent welding mask provided by this utility model allows the T-shaped column 12 to slide inside the housing 11 by pulling the connecting plate 10, and simultaneously causes the sliding column 9 to slide inside the support housing 8. Under the action of the second limiting component, the sliding column 9 is restricted from sliding into the support housing 8. When the connecting plate 10 is pulled, the distance between the support frame 17 and the mask body 1 can be adjusted. The threaded rod 18 can be rotated according to the operator's face shape, so that the height of the support frame 17 can be adjusted under the restriction of the limiting column 19 and the connecting plate 10. This allows the operator's chin to be on the support frame 17 when wearing the mask body 1. By pulling the connecting plate 10 to change the distance between the connecting plate 10 and the mask body 1, the distance between the support frame 17 and the mask body 1 can be changed accordingly, thereby changing the distance between the operator's face and the mask body 1. This allows the device to be worn by operators wearing various types of glasses for welding operations, reducing the discomfort caused by the mask body 1 pressing on the eyes and improving the practicality of the device.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 2-3 A smart welding mask, comprising:

[0039] The mask body 1 has an intelligent protection component 2 installed on it. A protective plate 3 is fixedly connected to the outer wall of the mask body 1. An adjustable headband 4 is rotatably connected to the inner wall of the protective plate 3. Straps 5 are fixedly connected to the outer wall of the mask body 1 near the left and right sides respectively. A support mechanism 6 is provided on the mask body 1. A protection replacement mechanism 7 is provided on the support mechanism 6. The adjustable headband 4 is prior art well known to those skilled in the art, so it will not be described in detail.

[0040] The support mechanism 6 includes a support shell 8, a sliding column 9, a connecting plate 10, a first limiting component, a second limiting component, and a rotating support component. The support shell 8 is fixedly connected to the outer wall of the mask body 1, and the sliding column 9 is slidably connected to the inner wall of the support shell 8. The connecting plate 10 is fixedly connected to one end of the sliding column 9 located outside the support shell 8. The support mechanism 6 can ultimately adjust the distance between the support frame 17 and the mask body 1 and the height of the support frame 17.

[0041] The first limiting component includes a housing 11. The outer wall of the mask body 1 and the left and right sides of the support housing 8 are respectively fixedly connected to the housing 11. The inner walls of the two housings 11 are respectively slidably connected to T-shaped posts 12. The ends of the two T-shaped posts 12 away from the mask body 1 are fixedly connected to the outer wall of the connecting plate 10. The first limiting component limits the sliding distance of the sliding post 9 relative to the support housing 8 to prevent the sliding post 9 from leaving the support housing 8.

[0042] The second limiting component includes ratchet 13. Multiple ratchet 13s are fixedly connected to the outer wall of the sliding column 9. A rotating rod 14 is rotatably connected to the inner wall of the support shell 8. A pawl 15 adapted to the ratchet 13 is fixedly connected to the outer wall of the rotating rod 14. Torsion springs 16 are respectively sleeved on the outside of the rotating rod 14 and on both sides of the pawl 15. The two ends of the torsion springs 16 are respectively fixedly connected to the outer wall of the pawl 15 and the inner wall of the support shell 8. The second limiting component can restrict the sliding column 9 from sliding into the support shell 8 or release the sliding restriction of the sliding column 9 into the support shell 8.

[0043] The rotating support assembly includes a threaded rod 18. The inner wall of the connecting plate 10 is threadedly connected to the threaded rod 18. The top end of the threaded rod 18 is rotatably connected to a support frame 17. The bottom of the support frame 17 and the left and right sides of the threaded rod 18 are respectively fixedly connected to limiting posts 19. Both limiting posts 19 are slidably connected to the inner wall of the connecting plate 10. The rotating support assembly can adjust the height of the support frame 17.

[0044] With the above structural design, when the device needs to be worn, the position of the support frame 17 is first adjusted according to the wearer's face shape and whether glasses are worn. By pulling the connecting plate 10, the T-shaped column 12 can slide inside the housing 11, and at the same time, the sliding column 9 can slide inside the support housing 8. Under the action of the second limiting component, the sliding column 9 is restricted from sliding into the support housing 8. When it is necessary to move the sliding column 9 into the support housing 8, the rotating rod 14 is rotated, which causes the pawl 15 to disengage from the ratchet 13, causing the torsion spring 16 to deform. Then, the connecting plate 10 can be pushed to make the sliding column 9 slide into the support housing 8. After the sliding column 9 is pushed into the support housing 8 to a suitable degree, the rotating rod 14 can be released, and the pawl can move into the support housing 8. 15 Under the elastic force of the torsion spring 16, it contacts the ratchet 13 again. When the connecting plate 10 is pulled to the appropriate position, the distance between the support frame 17 and the mask body 1 is adjusted to the appropriate position. The threaded rod 18 can be rotated according to the operator's face shape, so that the support frame 17 can be adjusted in height under the restriction of the limiting post 19 and the connecting plate 10. When the operator wears the mask body 1, the operator's chin can be on the support frame 17, and the mask body 1 will not cause uncomfortable pressure on the operator's face or the glasses worn by the operator. Then the operator's head is put into the adjustable headband 4 and the adjustable headband 4 is adjusted. Then the mask body 1 is further bound to the operator's head by the two straps 5.

[0045] Example 2:

[0046] The intelligent welding mask provided in Example 1 has been further optimized, specifically, as follows: Figures 3-5 As shown, the protection replacement mechanism 7 includes a soft pad 20. A plug rod 21 is fixedly connected to the bottom of the soft pad 20. The plug rod 21 is movably inserted into the support frame 17. Two U-shaped frames 23 are fixedly connected to the outer wall of the support frame 17. A mounting frame 22 is fixedly connected to the outer wall of the soft pad 20. The mounting frame 22 is movably inserted into the two U-shaped frames 23. The plug rod 21 and the mounting frame 22 are both made of rigid materials, while the soft pad 20 is made of soft materials.

[0047] The protective replacement mechanism 7 also includes a fixed housing 24 and a U-shaped handle 27. The outer walls of the two U-shaped frames 23 are fixedly connected to the fixed housing 24. The outer wall of the U-shaped handle 27 is slidably connected to the inner wall of the two fixed housings 24. The two ends of the U-shaped handle 27 pass through the two U-shaped frames 23 and are movably inserted into the mounting frame 22. The outer wall of the U-shaped handle 27 is fixedly connected to two fixed rings 25, which are slidably connected to the inner wall of the fixed housing 24. The outside of the U-shaped handle 27 is fitted with two springs 26. The two ends of the springs 26 are fixedly connected to the outer wall of the fixed rings 25 and the inner wall of the fixed housing 24, respectively. Pulling the U-shaped handle 27 can release the restriction between the U-shaped frame 23 and the mounting frame 22, and the soft pad 20 can be removed.

[0048] With the above structural design, when the pad 20 needs to be cleaned or replaced, pulling the U-shaped handle 27 allows the U-shaped handle 27 to slide relative to the two fixed shells 24, causing the fixed ring 25 to slide inside the fixed shell 24. This causes the spring 26 to deform, thereby causing the U-shaped handle 27 to leave the mounting bracket 22, thus releasing the restriction on the pad 20. The operator can then pull the mounting bracket 22 out of the U-shaped bracket 23 and the insertion rod 21 out of the support frame 17. Subsequently, the pad 20 can be rinsed according to the actual situation. A new or clean pad 20 can be taken out, and its corresponding mounting bracket 22 can be inserted into the U-shaped bracket 23, and the insertion rod 21 can be inserted into the support frame 17. Then, the U-shaped handle 27 can be released, and under the elastic force of the spring 26, the U-shaped handle 27 can pass through the U-shaped bracket 23 and be inserted into the mounting bracket 22.
