An adjustable welding helmet

Abstract

This utility model relates to the field of welding helmet technology, specifically an adjustable head-mounted welding helmet, comprising a welding helmet body, with rotating rods rotatably connected to both sides of the welding helmet body. This utility model involves holding a rectangular block, which in turn moves a circular block via a vertical block. The circular block moves a circular rod, stretching a spring. The circular rod then moves a pointed block, separating it from an arc-shaped rubber strip. Rotating the rectangular block to the left causes the vertical rod to rotate the protective cover via the rotating rods. The protective cover then rotates the goggles upwards. When the goggles are rotated to the appropriate position, the tension on the rectangular block is released, and the spring force causes the circular block to move backwards. The circular block, through the circular rod, moves the pointed block into close contact with the arc-shaped rubber strip. This gives the head-mounted welding helmet an adjustable function, facilitating adjustment of the protective cover's rotation angle without obstructing vision. It also facilitates breathing, drinking, and other operations, improving work efficiency and providing convenience for the user.

Description

Technical Field

[0001] This utility model relates to the field of welding cap technology, specifically an adjustable head-mounted welding cap. Background Technology

[0002] To avoid injury from welding arc light, welders need to use welding masks when performing welding operations. Commonly used masks are generally divided into handheld and head-mounted types. The head-mounted welding helmet has a protective cover installed on the front, and goggles are installed on the outside of the protective cover. The goggles serve to protect the eyes.

[0003] However, some current welding helmets do not have an adjustable function. The protective cover is mostly fixed to the welding helmet with bolts, which makes it inconvenient to adjust the rotation angle of the protective cover. After welding, when observation is needed, or for convenient breathing, drinking water, or when dust accumulates on the front of the goggles and affects the field of vision, the user still needs to remove the welding helmet from the head and repeat the operation, which reduces work efficiency and causes inconvenience to the user. Therefore, we propose an adjustable welding helmet to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable head-mounted welding cap to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable welding helmet, comprising a welding helmet body, with rotating rods rotatably connected to both sides of the welding helmet body, a protective cover fixedly fitted on the outer side of the two rotating rods, a goggle fixedly connected to the right side of the protective cover, a vertical rod fixedly fitted on the outer side of the front rotating rod, a connecting block fixedly connected to the front side of the welding helmet body, the connecting block rotatably fitted on the outer side of the front rotating rod, an arc-shaped rubber strip fixedly connected to the front side of the connecting block, a circular block provided on the front side of the vertical rod, a circular rod fixedly connected to the rear side of the circular block, the vertical rod slidably fitted on the outer side of the circular rod, a pointed block fixedly connected to the rear end of the circular rod, the tip of the pointed block being in close contact with the outer side of the arc-shaped rubber strip, and a spring fixedly connected between the vertical rod and the circular block, the spring being movably fitted on the outer side of the circular rod.

[0006] More preferably, a limiting block is fixedly sleeved on the outer side of the round rod, and a vertical block is fixedly connected to the bottom of the round block.

[0007] More preferably, a rectangular rod is fixedly connected to the rear side of the vertical block, and a positioning rod is fixedly connected to the front side of the vertical rod.

[0008] More preferably, the rectangular rod is slidably sleeved on the outside of the positioning rod, and a rectangular block is fixedly connected to the front side of the vertical block.

[0009] More preferably, the bottom of the welding cap body is fixedly connected to two fixing blocks.

[0010] More preferably, an elastic band is fixedly connected to the bottom of the fixing block, and a male Velcro fastener is fixedly connected to the front side of one of the elastic bands on the rear side.

[0011] More preferably, a female hook and loop fastener is fixedly connected to the front side of one of the elastic bands, and the male hook and loop fastener cooperates with the female hook and loop fastener.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model allows the rectangular block to be held, which in turn moves the circular block via the vertical block. The circular block then moves the circular rod, stretching the spring. The circular rod moves the pointed block, separating it from the arc-shaped rubber strip. Rotating the rectangular block to the left causes the vertical rod to rotate the protective cover via the rotating rod. The protective cover then rotates the goggles upwards. When the goggles are rotated to the appropriate position, the tension on the rectangular block is released. The spring force causes the circular block to move backwards. The circular block, through the circular rod, moves the pointed block to make close contact with the arc-shaped rubber strip. This gives the welding helmet an adjustable function, facilitating the adjustment of the protective cover's rotation angle without obstructing vision. It also facilitates breathing, drinking, and other operations, improving work efficiency and providing convenience for the user. Attached Figure Description

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.

[0019] Example

[0020] Please see Figure 1-4 This utility model provides a technical solution: an adjustable welding helmet, including a welding helmet body 1, with rotating rods 2 rotatably connected to both sides of the welding helmet body 1. A protective cover 3 is fixedly fitted onto the outer side of both rotating rods 2. A goggle 4 is fixedly connected to the right side of the protective cover 3. A vertical rod 5 is fixedly fitted onto the outer side of one of the rotating rods 2 on the front side. A connecting block 6 is fixedly connected to the front side of the welding helmet body 1, rotatably fitted onto the outer side of one of the rotating rods 2 on the front side. An arc-shaped rubber strip 7 is fixedly connected to the front side of the connecting block 6. A circular block 8 is provided on the front side of the vertical rod 5. A circular rod 9 is fixedly connected to the rear side of the circular block 8. The vertical rod 5 is slidably fitted onto the outer side of the circular rod 9. A pointed block 10 is fixedly connected to the rear end of the circular rod 9. The tip of the pointed block 10 is in close contact with the outer side of the arc-shaped rubber strip 7. A spring is fixedly connected between the vertical rod 5 and the circular block 8. Spring 11 is movably sleeved on the outside of round rod 9. Holding rectangular block 16 moves round block 8 via vertical block 13. Round block 8 moves round rod 9, stretching spring 11. Round rod 9 moves pointed block 10, separating it from arc-shaped rubber strip 7. Rotating rectangular block 16 to the left causes vertical rod 5 to rotate protective cover 3 via rotating rod 2. Protective cover 3 rotates goggles 4 upward. When goggles 4 rotates to the appropriate position, the tension on rectangular block 16 is released. The elastic force of spring 11 moves round block 8 backward. Round block 8 moves pointed block 10 via round rod 9, making it in close contact with arc-shaped rubber strip 7. This gives the welding helmet an adjustable function, facilitating the adjustment of the rotation angle of protective cover 3 without affecting vision. It also facilitates breathing, drinking, and other operations, improving work efficiency and providing convenience for users.

[0021] In this embodiment, specifically: a limiting block 12 is fixedly sleeved on the outer side of the round rod 9, and a vertical block 13 is fixedly connected to the bottom of the round block 8;

[0022] In this embodiment, specifically: a rectangular rod 14 is fixedly connected to the rear side of the vertical block 13, and a positioning rod 15 is fixedly connected to the front side of the vertical rod 5;

[0023] In this embodiment, specifically: the rectangular rod 14 is slidably sleeved on the outside of the positioning rod 15, and the front side of the vertical block 13 is fixedly connected to the rectangular block 16;

[0024] In this embodiment, specifically: two fixing blocks 17 are fixedly connected to the bottom of the welding cap body 1;

[0025] In this embodiment, specifically: the bottom of the fixing block 17 is fixedly connected to an elastic band 18, and the front side of the rear elastic band 18 is fixedly connected to a male Velcro 19.

[0026] In this embodiment, specifically: a female hook and loop fastener 20 is fixedly connected to the front side of an elastic band 18, and a male hook and loop fastener 19 cooperates with the female hook and loop fastener 20.

[0027] In operation: When in use, the male Velcro 19 and female Velcro 20 work together to secure the welding cap body 1 to the user's head. After welding, the protective cover 3 and goggles 4 are rotated upwards. The rectangular block 16 is then grasped and moved forward. The rectangular block 16 moves the vertical block 13, which in turn moves the rectangular rod 14. The rectangular rod 14 slides outside the corresponding positioning rod 15. The vertical block 13 moves the circular block 8, which in turn moves the circular rod 9. During this movement, the circular block 8 stretches the spring 11. The circular rod 9 moves the pointed block 10, separating it from the arc-shaped rubber strip 7. Next, the rectangular block 16 is rotated to the left. The rectangular block 16, through the rectangular rod 14, moves the positioning rod 15 to the left. The positioning rod 15 then rotates the vertical rod 5. Rod 5 drives rotating rod 2 to rotate, rotating rod 2 drives protective cover 3 to rotate, protective cover 3 drives goggles 4 to rotate upward. When goggles 4 rotates upward to the appropriate position, the tension on rectangular block 16 is released. At this time, spring 11, which is in a stretched state, returns to its original position. The elastic force of spring 11 drives circular block 8 to move backward. Circular block 8 drives circular rod 9 to move. Circular rod 9 drives pointed block 10 to move and make close contact with arc-shaped rubber strip 7, thereby fixing protective cover 3 after it rotates upward. This adjusts the rotation angle of protective cover 3, thus forming an adjustable head-mounted welding helmet. This makes the head-mounted welding helmet adjustable, which facilitates adjusting the rotation angle of protective cover 3 without affecting vision. It also facilitates breathing, drinking water, and other operations, improving work efficiency and bringing convenience to the user.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
