Description

Technical Field

[0001] The utility model relates to the technical field of electric welding, and more specifically to an electric welding protective device. Background Art

[0002] There are many hazards in the welding process, so it is necessary to wear protective equipment, such as safety helmets and protective masks. Electric welders will be directly exposed to toxic gases produced by welding during welding operations. In addition, the temperature of welding is very high, and welding sparks will be generated during the welding process. Workers exposed to such an environment during the welding process will be in danger of burns and scalds caused by welding flames or candle parts. In addition, workers are often exposed to radiation hazards during welding, such as strong light, infrared rays, ultraviolet rays, etc., which will affect the health of workers.

[0003] At present, the safety helmet and protective mask of welders are usually separate, that is, when a welder wears a safety helmet for welding, he needs to hold the protective mask in one hand and hold the welding gun in the other hand for welding; there are also protective devices on the market that integrate the safety helmet and the protective mask.

[0004] However, the welding protection devices currently used have at least the following two shortcomings, in other words, they are the technical problems to be solved by the present utility model:

[0005] 1. Low efficiency. For the split type, one hand holds the welding mask while the other hand operates the welding gun. This operation method not only reduces work efficiency, but also greatly increases the risk of operating errors and accidents.

[0006] 2. Non-adjustable. For a safety helmet and a protective mask that are integrated, when a worker wants to adjust the protective mask, the protective mask cannot be adjusted because the protective mask and the safety helmet are integrated.

[0007] In summary, a welding protection device is now urgently needed to solve the deficiencies of the prior art. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the specific implementation of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the present invention.

[0043] A welding protective device, as attached Figure 1 To Attachment Figure 5 As shown, the electric welding protection device comprises: a safety helmet 1, a connecting assembly 2 and a protective mask 3. The connecting assembly 2 comprises: a connecting rod 21 and a mask angle adjustment structure 22.

[0044] Specifically, the first end of the connecting rod 21 is connected to the safety helmet 1, and the second end of the connecting rod 21 is connected to the mask angle adjustment structure 22, and the mask angle adjustment structure 22 is connected to the protective mask 3. The safety helmet 1 and the protective mask 3 are connected together through the connecting assembly 2, and since the connecting assembly 2 includes the mask angle adjustment structure 22, the protective mask 3 can be turned over. Therefore, the welder can adjust the protective mask 3 through the mask angle adjustment structure 22 when the angle needs to be adjusted, thus avoiding the worker holding the welding mask with one hand and operating the welding gun with the other hand during welding work, thereby improving work efficiency and ensuring the safety of welding work.

[0045] Furthermore, as attached Figure 2 , Attachment Figure 3 As shown, the mask angle adjustment structure 22 includes: a sphere 221, which is connected to the second end of the connecting rod 21; a ball seat 222, the axial first end of the ball seat 222 is connected to the protective mask 3, a ball cavity for accommodating the sphere 221 is provided inside the ball seat 222, a through hole c connected to the ball cavity and allowing the connecting rod 21 to pass through is provided at the axial second end of the ball seat 222, and a radial notch d is provided at the axial second end of the ball seat 222, the radial notch d is connected to the through hole c and the outer peripheral side of the ball seat 222, and a locking thread is provided on the outer peripheral side of the ball seat 222; a rotating nut 223, the rotating nut 223 is sleeved on the connecting rod 21, and the inner side of the rotating nut 223 is provided with a docking thread assembled and connected with the locking thread.

[0046] On the basis of the above, the mask angle adjustment structure 22 includes a ball 221, a ball seat 222 and a rotating nut 223, wherein the ball 221 is connected to the second end of the connecting rod 21, the axial first end of the ball seat 222 is connected to the protective mask 3, and a ball cavity for accommodating the ball 221 is provided inside the ball seat 222, a through hole c is provided at the axial second end of the ball seat 222, which is connected to the ball cavity and allows the connecting rod 21 to pass through, and a radial notch d is also provided at the axial second end of the ball seat 222, and the radial notch d is connected to the through hole c and the outer peripheral side of the ball seat 222, and finally, a locking thread is also provided on the outer peripheral side of the ball seat 222. The rotating nut 223 is sleeved on the connecting rod 21, and the inner side of the rotating nut 223 is provided with a butt thread assembled and connected with the locking thread.
