DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] Embodiment 1

[0025] The present embodiment provides a welding mask connecting structure based on a safety helmet, as shown in the figure, the connecting structure includes a safety helmet body 1 and a welding mask 2, an assembly groove 11 pre-set on the safety helmet body 1, a main frame 3 arranged in the assembly groove 11 for connecting the safety helmet body 1 and the welding mask 2, an adjustable leg 4 fixedly installed on the main frame 3, and a rotary adjusting mechanism 5 fixedly installed on the main frame 3 for locking the welding mask 2: Figures 1-6 The adjustable leg 4 includes a fixed leg 41 fixedly installed on the main frame 3 and a movable leg 42 slidably installed on the main frame 3 opposite to the fixed leg 41, and the fixed leg 41 and the movable leg 42 are inserted into the assembly groove 11;

[0026] The main frame 3 is rotatably installed with a movable leg adjusting screw 43, the movable leg adjusting screw 43 is arranged in sequence through the outer wall of the main frame 3, the movable leg 42, the fixed leg 41, and the inner wall of the main frame 3, the main frame 3 and the fixed leg 41 are rotatably connected with the movable leg adjusting screw 43, and the movable leg 42 is screwed on the movable leg adjusting screw 43.

[0027]

[0028] ​In use, the welding mask 2 is mounted on the main body frame 3 through the rotary adjusting mechanism 5, then the movable leg adjusting screw 43 is rotated to make the movable leg 42 slide on the movable leg adjusting screw 43, thereby reducing the distance between the fixed leg 41 and the movable leg 42, then the main body frame 3 is inserted into the preset assembly groove 11 through the fixed leg 41 and the movable leg 42, then the movable leg adjusting screw 43 is reversed to make the movable leg 42 slide on the movable leg adjusting screw 43, thereby expanding the distance between the fixed leg 41 and the movable leg 42, so that the fixed leg 41 and the movable leg 42 support the inner wall of the assembly groove 11 from both sides, thereby completing the assembly of the main body frame 3, completing the quick assembly of the safety helmet body 1 and the welding mask 2, and being able to adapt to different sizes of the assembly groove 11, greatly improving the application range of the equipment and being more convenient to use.

[0029] Specifically, the fixed leg 41 and the movable leg 42 are fixedly installed with clamping protrusions 44 on the surfaces away from each other at the ends away from the main body frame 3.

[0030] In use, after the fixed leg 41 and the movable leg 42 are clamped into the assembly groove 11, the clamping protrusions 44 clamp the assembly groove 11 from the bottom end, thereby preventing the main body frame 3 from being separated from the assembly groove 11 in the longitudinal direction, and achieving good anti-separation effect.

[0031] More specifically, the fixed leg 41 and the movable leg 42 are provided with clamping teeth 45 in linear array distribution on the surfaces away from each other on the outer side walls, and the clamping teeth 45 abut against the inner side walls of the assembly groove 11.

[0032] In use, after the fixed leg 41 and the movable leg 42 are clamped into the assembly groove 11, the fixed leg 41 and the movable leg 42 increase the friction with the inner side walls of the assembly groove 11 through the clamping teeth 45, so that the main body frame 3 is not easily shifted up and down after installation, and the connection is stable.

[0033] Embodiment 2

[0034] Different from embodiment 1, when assembling an additional gas mask, the position-fixed welding mask 2 is limited and inconvenient to install, therefore, the rotary adjusting mechanism 5 includes two positioning blocks 51 fixedly installed on the main body frame 3 and arranged in an up-down staggered manner, first insertion holes 52 are formed in the two positioning blocks 51, sliding rails 53 made of stainless steel and designed in a U shape are inserted into the first insertion holes 52, rail top screws 54 extending into the first insertion holes 52 are screwed on the two positioning blocks 51, and the welding mask 2 is rotatably installed on the sliding rails 53.

[0035] In use, the sliding rail 53 is inserted into the first insertion hole 52 of the positioning block 51, and the sliding rail 53 is moved on the positioning block 51 according to the required assembly of the additional gas mask model. After adjustment, the rail top wire 54 is screwed into the positioning block 51 to resist the sliding rail 53, and the position of the sliding rail 53 is fixed. The welding mask 2 connected to the sliding rail 53 can move a large distance in front of the safety helmet body 1, thereby expanding the use space between the welding mask 2 and the safety helmet body 1, so as to adapt to the assembly of more gas masks.

[0036] Specifically, the sliding rail 53 is slidably installed with a sliding screw 55, and the end of the sliding screw 55 is provided with a second insertion hole 56. The sliding screw 55 is slidably installed on the sliding rail 53 through the second insertion hole 56.

[0037] In use, before the sliding rail 53 is inserted into the positioning block 51, the sliding screw 55 is inserted into the sliding rail 53 through the second insertion hole 56 at the end, so that the sliding screw 55 can slide on the sliding rail 53 during subsequent installation of the mask connecting piece 59, further adjusting the position of the welding mask 2 to wear more different models of gas masks.

[0038] Further, the sliding screw 55 is sequentially sleeved with a stainless steel gasket 57, a damping silica gel pad 58, a mask connecting piece 59, an integral bearing 510 and a hand screw nut 511 from the end close to the sliding rail 53 to the end away from the sliding rail 53. The stainless steel gasket 57, the damping silica gel pad 58, the mask connecting piece 59, the integral bearing 510 and the hand screw nut 511 are all provided with a threaded hole adapted to the sliding screw 55 at the center position. The mask connecting piece 59 is integrally formed with the welding mask 2.

[0039] In use, the stainless steel gasket 57, the damping silica gel pad 58, the mask connecting piece 59, the integral bearing 510 and the hand screw nut 511 are sequentially screwed on the sliding screw 55. The hand screw nut 511 and the sliding screw 55 play a fastening role. The integral bearing 510 can offset the rotating torque when the welding mask 2 moves up and down, so as not to cause the hand screw nut 511 to rotate and loosen. The mask connecting piece 59 is an extension of the welding mask 2 and is used to support the welding mask 2. The damping silica gel pad 58 has a damping phenomenon with the mask connecting piece 59, so that the mask connecting piece 59 does not move freely in use. The stainless steel gasket 57 plays a fixing role, facilitating assembly and disassembly and operation.

[0040] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change within the technical range disclosed in the present application according to the technical solution and concept of the present application, which should be covered within the protection scope of the present application.
