Description
Technical Field
[0001] This utility model relates to the field of protective clothing technology, specifically to a protective clothing that is easy to assemble and disassemble for welding operations. Background Technology
[0002] Protective clothing includes fire-fighting protective clothing, industrial protective clothing, medical protective clothing, military protective clothing, and protective clothing for special groups. Electric welding, commonly known as shielded metal arc welding, is a welding operation that uses a welding rod to melt metal parts that need to be joined by passing it through an electric arc at high temperatures. During welding, molten metal splashes onto the worker's ordinary clothing, causing it to burn. The residual heat and latent heat released when the molten metal cools and solidifies often burn through the clothing. Furthermore, welding slag is produced during welding, and the slag, in the form of fine particles, flies out and forms dust. Therefore, flame-retardant materials are used to make welding protective clothing on the market.
[0003] Utility model patent document CN209609906U discloses a welding protective suit, specifically including a top and trousers. Both the top and trousers are made of flame-retardant core-spun yarn, which is made of PSA fiber wrapped with cotton fiber. The sleeves of the top and the trouser legs are made of a mixture of core-spun yarn and coaxial fiber triboelectric nanogenerator. Semiconductor cooling pads are provided on the inner side of the armpits of the top and the inner side of the crotch of the trousers. The external circuit of the coaxial fiber triboelectric nanogenerator is connected to the semiconductor cooling pads to supply power.
[0004] In industries such as automobiles and high-speed rail, welders often work on machinery for extended periods. Welders typically wear protective suits made of flame-retardant materials. They hold a welding torch in one hand and a mask in the other, covering their head and the collar of the protective suit. During welding, molten metal and weld slag splatter outwards, some of which lands on the chest area of the protective suit, cools, solidifies, and adheres to it. Figure 1 As shown, after a long period of welding work, welding slag dust 15 continuously accumulates on the chest area of the protective suit 1. After finishing the welding work, the welder puts down the mask and welding gun. When walking, running or other activities, the welding slag dust 15 on the chest area of the protective suit 1 is easily blown outward due to vibration. Since it is close to the welder's head, the welder's mouth and nose are easily inhaled by the flying welding slag dust, which is detrimental to the welder's health.
[0005] Therefore, how to prevent molten metal and welding slag from splashing onto the chest area of the protective suit is a technical problem that urgently needs to be solved in this field. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a protective suit that is easy to assemble and disassemble for welding operations, so as to avoid molten metal and welding slag from splashing onto the chest area of the protective suit.
[0007] The technical solution adopted by this utility model is: a protective suit for easy assembly and disassembly during electric welding operations, comprising:
[0008] Protective suit body, stainless steel isolation plate, Velcro;
[0009] The stainless steel isolation plate is located in front of the chest of the protective suit body. The top of the stainless steel isolation plate has a left curved end, a middle arc-shaped opening and a right curved end. The middle arc-shaped opening accommodates the collar of the protective suit body. The left curved end is placed on the left shoulder of the protective suit body and the right curved end is placed on the right shoulder of the protective suit body. The bottom of the stainless steel isolation plate has a welding slag dust collection groove. The welding slag dust collection groove is higher than the waist of the protective suit body. The stainless steel isolation plate is connected to the protective suit body by the Velcro.
[0010] Furthermore, the Velcro is divided into a first Velcro and a second Velcro. The first Velcro is located between the left curved end of the stainless steel isolation plate and the left shoulder of the protective suit body, and the second Velcro is located between the right curved end of the stainless steel isolation plate and the right shoulder of the protective suit body.
[0011] Furthermore, the Velcro is further divided into a third Velcro, which is located between the bottom of the stainless steel isolation plate and the abdomen of the protective suit body.
[0012] Furthermore, the loop side of the Velcro is fixedly connected to the protective clothing body, and the hook side of the Velcro is fixedly connected to the stainless steel isolation plate.
[0013] Furthermore, the welding slag dust collection tank is an arc-shaped tank, and the opening of the welding slag dust collection tank faces vertically upward.
[0014] Furthermore, a baffle is fixedly installed at one end of the welding slag dust collection tank, and a discharge hole is provided at the other end, wherein the discharge hole is slidably connected to the insert plate.
[0015] Compared with the prior art, the beneficial effects or advantages of this utility model are as follows: A stainless steel isolation plate is set in front of the chest of the protective suit body. The molten metal generated during the welding process splashes onto the stainless steel isolation plate, preventing the molten metal and welding slag generated during welding from splashing onto the chest area of the protective suit body. Since the splashed molten metal and welding slag are isolated, the chest area of the protective suit body is relatively clean after the stainless steel isolation plate is removed. This prevents welding slag dust from flying outward from the chest area of the protective suit body when the welding workers are moving around, thereby helping to reduce the inhalation of welding slag dust by the mouth and nose of the welding workers and benefiting the health of the welding workers. The left and right curved ends of the stainless steel isolation plate are hooked and placed on the left and right shoulders of the protective suit body, respectively, which helps to prevent the stainless steel isolation plate from falling off during the installation process. The stainless steel isolation plate is connected to the protective suit body by Velcro, which makes it easy to detach the protective suit body from the stainless steel isolation plate. Molten metal and welding slag that splash onto the stainless steel isolation plate will fall into the welding slag dust collection tank after cooling and solidification. The stainless steel isolation plate also plays a role in strengthening the protection of the chest area of the protective suit body. Attached Figure Description

Detailed Implementation
[0024] This utility model embodiment provides a protective suit that is easy to assemble and disassemble for welding operations. The overall concept of the technical solution is as follows:
[0025] In industries such as automobiles and high-speed rail, welders first don the main body of a protective suit. Then, they place the left-curved end of a stainless steel shielding plate on the left shoulder of the suit and the right-curved end on the right shoulder. The collar of the suit is positioned at the central arc-shaped opening of the shielding plate, which is secured to the suit with Velcro. The welder holds a welding torch in one hand and a mask in the other, covering their head and the collar of the suit. During welding, molten metal and slag splatter outwards, landing on the shielding plate where they cool and solidify. The accumulated slag dust falls into a dust collection trough, preventing molten metal and slag from splashing onto or adhering to the chest area of the suit. The mask effectively prevents welders from inhaling slag dust through their mouth and nose. At the end of the welding operation, the welder puts down the welding gun and mask, and then removes the stainless steel isolation plate from the protective suit. Because the stainless steel isolation plate greatly blocks molten metal and welding slag, the chest area of the protective suit is relatively clean. This prevents welding slag dust from flying out of the chest area of the protective suit when the welder continues to wear it, thus helping to reduce the inhalation of welding slag dust through the welder's mouth and nose, which is beneficial to the welder's health.
[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0027] See Figures 1 to 6 The preferred embodiment of this utility model.
[0028] A protective suit for welding operations that is easy to assemble and disassemble includes:
[0029] 1. Protective suit body; 2. Stainless steel isolation plate; 3. Velcro;
[0030] The stainless steel isolation plate 2 is located in front of the chest of the protective suit body 1. The top of the stainless steel isolation plate 2 has a left curved end 21, a middle arc-shaped opening 22 and a right curved end 23. The middle arc-shaped opening 22 accommodates the collar 13 of the protective suit body 1. The left curved end 21 is placed on the left shoulder 11 of the protective suit body 1, and the right curved end 23 is placed on the right shoulder 12 of the protective suit body 1. The bottom of the stainless steel isolation plate 2 has a welding slag dust collection groove 24. The welding slag dust collection groove 24 is higher than the waist 14 of the protective suit body 1. The stainless steel isolation plate 2 and the protective suit body 1 are connected by the Velcro 3.
[0031] The beneficial effects or advantages of this utility model are as follows: A stainless steel isolation plate 2 is set in front of the chest of the protective clothing body 1. The molten metal generated during the welding process splashes onto the stainless steel isolation plate 2, preventing the molten metal and welding slag generated during welding from splashing onto the chest of the protective clothing body 1. Since the splashed molten metal and welding slag are isolated, the chest of the protective clothing body 1 is relatively clean after the stainless steel isolation plate 2 is removed. This prevents welding slag dust 15 from flying outward from the chest of the protective clothing body 1 when the welding workers are active, thereby helping to reduce the inhalation of welding slag dust 15 by the mouth and nose of the welding workers, which is beneficial to the health of the welding workers. The left bent end 21 and right bent end 23 of the stainless steel isolation plate 2 are hooked and placed on the left shoulder 11 and right shoulder 12 of the protective suit body 1, respectively, which helps to prevent the stainless steel isolation plate from falling off during the installation of the stainless steel isolation plate 2; the stainless steel isolation plate 2 is connected to the protective suit body 1 by Velcro 3, which makes it easy to disassemble and assemble the protective suit body 1 and the stainless steel isolation plate 2; the molten metal and welding slag that splash onto the stainless steel isolation plate 2 are cooled and solidified and fall into the welding slag dust collection tank 24 when they fall downwards; the stainless steel isolation plate 2 also plays a role in strengthening the protection of the chest area of the protective suit body 1.
[0032] The stainless steel isolation plate 2 is a thin sheet of stainless steel used to isolate molten metal from directly splashing onto the protective suit during the welding process. It also features rapid heat dissipation, preventing the heat from the molten metal from concentrating. The shapes of the left-curved end 21 and right-curved end 23 of the stainless steel isolation plate 2 do not restrict the welder's arm movements when using the welding torch and mask. The shape of the stainless steel isolation plate 2 matches or conforms to the shape of the protective suit, and it can be manufactured using existing 3D printing technology. The stainless steel isolation plate 2 also strengthens the protection of the chest area of the protective suit and is durable and resistant to damage. The side of the stainless steel isolation plate 2 facing the protective suit body 1 has a heat-insulating layer using existing technology, which helps reduce the heat transfer from the molten metal and welding slag to the chest area of the protective suit body 1 and the human body.
[0033] Furthermore, the Velcro is divided into a first Velcro 31 and a second Velcro 32. The first Velcro 31 is located between the left curved end 21 of the stainless steel isolation plate 2 and the left shoulder 11 of the protective suit body 1, and the second Velcro 32 is located between the right curved end 23 of the stainless steel isolation plate 2 and the right shoulder 12 of the protective suit body 1.
[0034] The beneficial effects of this technical solution are as follows: when the left curved end 21 of the stainless steel isolation plate 2 is placed on the left shoulder 11 of the protective suit, it can be fixed by the first Velcro 31; when the right curved end 23 of the stainless steel isolation plate 2 is placed on the right shoulder 12 of the protective suit, it can be fixed by the second Velcro 32. This not only prevents the stainless steel isolation plate 2 from falling off during installation, but also improves the efficiency of fixing the stainless steel isolation plate 2 to the protective suit.
[0035] Furthermore, the Velcro is further divided into a third Velcro 33, which is located between the bottom of the stainless steel isolation plate 2 and the abdomen of the protective suit body 1.
[0036] The beneficial effects of this technical solution are: improved connection strength between the stainless steel isolation plate 2 and the protective clothing. The specifications of the stainless steel isolation plate 2 are not unique; multiple specifications of stainless steel isolation plates can be selected based on the actual welding workbench and the height of the welding operator; the bottom of the stainless steel isolation plate 2 is located between the chest and waist of the human body.
[0037] Furthermore, the loop side of the Velcro is fixedly connected to the protective clothing body 1, and the hook side of the Velcro is fixedly connected to the stainless steel isolation plate 2.
[0038] The beneficial effects of this technical solution are as follows: Velcro is an existing technology; it achieves a fixed installation when the hook side contacts the rough side. When the welding operator pulls it off forcefully, the hook side can be detached from the rough side.
[0039] Furthermore, the slag collection trough is an arc-shaped trough, and the opening 241 of the slag collection trough faces vertically upward.
[0040] The beneficial effects of this technical solution are: when the welding slag accumulated on the surface of the stainless steel isolation plate 2 falls downward due to gravity, it enters the welding slag collection tank through the groove 241, thus avoiding the spread and pollution of welding slag.
[0041] Furthermore, a baffle 242 is fixedly provided at one end of the slag collection tank, and a slag discharge hole 243 is provided at the other end. The slag discharge hole 243 is slidably connected to the insert plate 244.
[0042] The beneficial effects of this technical solution are as follows: When cleaning the stainless steel isolation plate 2 is required, the welding operator uses tools such as a brush to clean the surface of the stainless steel isolation plate 2, and pulls the insert plate 244 out of the slag discharge hole 243. A collection bucket is placed below the slag discharge hole 243, and the slag in the slag collection tank is swept out with a brush. The slag falls from the slag discharge hole 243 into the collection bucket. After cleaning, the insert plate 244 is reinserted into the slag discharge hole 243. The baffle plate 242 and the insert plate 244 cooperate to prevent slag from falling out from both ends of the slag collection tank.
[0043] This utility model provides a convenient disassembly and assembly protective suit for welding operations. A stainless steel isolation plate 2 is installed in front of the chest of the protective suit. The stainless steel isolation plate 2 can be easily disassembled and assembled using Velcro. When the welder is working, he holds a welding gun in one hand and a mask in the other hand. The mask covers the welder's head and the collar 13 of the protective suit. During the welding process, molten metal and welding slag splash onto the stainless steel isolation plate 2, preventing molten metal and welding slag from splashing onto or adhering to the chest area of the protective suit body 1. Because a mask is used, welding slag dust 15 is not easily inhaled by the welder's mouth and nose. After completing the welding operation, the welder puts down the welding torch and mask, and then removes the stainless steel isolation plate 2 from the protective suit body 1. Because the stainless steel isolation plate 2 significantly blocks molten metal and welding slag, the chest area of the protective suit body 1 remains relatively clean. This prevents welding slag dust 15 from flying outwards from the chest area of the protective suit body 1 when the welder continues to wear it, thus helping to reduce the inhalation of welding slag dust 15 by the welder's mouth and nose, and contributing to the welder's health. After cleaning the stainless steel isolation plate 2 and the welding slag powder collection tank with a brush, the stainless steel isolation plate 2 is reinstalled on the protective suit body 1 for the next welding operation. The stainless steel isolation plate 2 also serves to reinforce the protection of the chest area of the protective suit body and is characterized by its sturdiness, durability, and resistance to damage.
