Description

Technical Field

[0001] This utility model relates to the field of functional protective clothing technology, and in particular to a two-piece tight-fitting welding suit with flame-retardant function. Background Technology

[0002] Welding is a common high-risk process in shipbuilding, repair, and related industries. Because the working environment is often in confined spaces (such as inside ship cabins or pipe welding areas), workers frequently need to bend over, bend their knees, and extend their arms, placing higher demands on the flexibility, adaptability, and protective performance of protective clothing. Traditional welding protective clothing typically has a loose design, which provides basic protection, but in confined spaces it is prone to snagging on surrounding equipment and structures, hindering movement and even increasing safety hazards.

[0003] To address the aforementioned issues, existing technologies are increasingly incorporating slim-fit welding work clothes. These clothes reduce the contact area between the garment and the external environment, thereby decreasing the likelihood of snagging, while also conforming to the body's contours to improve mobility in confined spaces.

[0004] However, such fitted designs reveal significant contradictions in practical applications: while the tight cut of the clothing can adapt to narrow spaces, it excessively restricts the range of motion of the human joints, especially in key areas such as the shoulders, elbows, and knees. This can easily lead to stiffness and increased fatigue among workers, and may cause muscle strain under long-term work. It can even reduce operational accuracy due to limited movement, thus affecting work safety and efficiency. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a two-piece tight-fitting welding suit with flame-retardant function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A two-piece tight-fitting welding suit with flame-retardant function includes a two-piece top and pants. The back two sides of the top are respectively provided with obliquely extended pleated structures. The pleated structures are distributed in multiple levels along the movement direction from the human shoulder blade to the armpit, and the pleat axis is inclined at an angle relative to the human spinal axis.

[0008] Preferably, the collar of the top adopts an adjustable stand-up collar structure, and a drawstring assembly is embedded at the neckline to achieve adjustment of tightness.

[0009] Preferably, the upper ends of both sides of the chest of the top are respectively provided with:

[0010] A horizontal multi-functional chest pocket, the interior of which is provided with multiple storage spaces of different sizes;

[0011] The slanted, three-dimensional slip pockets are equipped with magnetic snaps at the openings for easy one-handed operation.

[0012] Preferably, the outer side of the upper arm sleeve of the garment is provided with an upper arm pocket, and the opening of the upper arm pocket is fastened with Velcro for quick opening and closing.

[0013] Preferably, a waist-cinching tie is sewn at the back waist of the top, and snap-on ties are sewn on both sides of the waist of the top, with the ends of the snap-on ties being fixed to the waist-cinching tie by a snap fastener structure.

[0014] Preferably, reflective strips are provided on the cuffs, the outer side of the waist tie, the shoulders, the upper part of the chest, and the legs of the trousers.

[0015] Preferably, the knee area of ​​the trousers is provided with a removable cushioning pad, which is connected to the trousers by Velcro and is filled with fire-retardant sponge.

[0016] Preferably, the trouser leg is closed by a zipper and the outer side of the trouser leg is provided with a Velcro closure for adjusting the tightness of the trouser leg.

[0017] Preferably, the trousers have an accordion-style tool pocket on the side of the leg section. The accordion-style tool pocket has multi-level stretch pleats formed by folding the fabric on both sides, and is flush with the trouser surface when closed.

[0018] Preferably, both the top and the trousers are made of aramid material and manufactured using a warp and weft interlacing process.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes a pleated structure with a retractable, layered folding design to provide axial extension during shoulder and elbow joint movements. This accommodates the multi-angle movement requirements of the upper limbs, including extension, abduction, and retraction. The unfolding direction of the oblique pleats matches the natural movement trajectory of the human upper limbs. In a static wearing state, this maintains the fit of the back piece of the garment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1 and Figure 2 A two-piece tight-fitting welding suit with flame-retardant function includes a two-piece top 1 and pants 2. The back two sides of the top 1 are respectively provided with obliquely extended pleated structures 3. The pleated structures 3 can be integrally formed by hot pressing the outer aramid protective fabric and the inner high-elastic knitted fabric, which ensures both fire resistance and elasticity. The elasticity can quickly pull the pleats back to their original position and avoid redundant deformation of the garment. The pleated structures 3 are distributed in multiple folds along the movement direction from the human shoulder blade to the armpit. The pleat axis is set at an angle of 45 degrees relative to the human spinal axis, and the pleat amount is 1.5cm.

[0026] This application utilizes a pleated structure 3, which employs a stretchable, layered folding design to provide axial extension during shoulder and elbow joint movements. This accommodates the multi-angle movement requirements of the upper limbs, including forward extension, abduction, and retraction. The unfolding direction of the oblique pleats is adapted to the natural movement trajectory of the human upper limbs. In a static wearing state, this maintains the fit of the back piece of the garment. During dynamic operations, the unfolding of the pleats releases excess space, thereby alleviating the constraint on the range of motion of the limbs caused by the fitted design of the garment. This solves the problem of inconvenience in movement associated with fitted garments in the prior art.

[0027] In this embodiment, the length of the top 1 can be extended by 5-10cm compared to the conventional design, covering the area below the buttocks to avoid exposing the waist when bending over to work.

[0028] In this embodiment, the collar of the top 1 adopts an adjustable stand-up collar structure 4, and a drawstring assembly 5 is embedded in the collar. The drawstring is an elastic drawstring, and the two ends of the drawstring pass through the inside of the collar of the top 1 to the outside of the collar on the back of the top 1 and are tied together. The tightness can be adjusted by pulling the two ends of the drawstring, while taking into account both the protective airtightness and the freedom of neck movement, and preventing sparks from entering the clothing and burning the skin.

[0029] In this embodiment, the upper ends of both sides of the chest of the top 1 are respectively provided with:

[0030] A horizontal multi-functional chest pocket 6, wherein the interior of the horizontal multi-functional chest pocket 6 is provided with multiple storage spaces of different sizes;

[0031] The slanted three-dimensional pocket 7 has a slanted side that forms the pocket opening. The inner wall of the pocket opening and the surface of the top 1 can be equipped with matching magnetic snaps for easy one-handed operation.

[0032] In this embodiment, an upper arm pocket 8 is provided on the outer side of the upper arm sleeve of the upper garment 1. The opening of the upper arm pocket 8 is fastened by Velcro (the Velcro side is on the surface of the upper garment 1, and the Velcro side is at the opening) to achieve quick opening and closing.

[0033] In this embodiment, a waist-cinching tie 9 is sewn at the back waist of the upper garment 1, and fastening ties 10 are sewn on both sides of the waist of the upper garment 1. The ends of the fastening ties 10 are fixed to the waist-cinching tie 9 by a snap fastener structure 11 (the female snap fastener is sewn on the end of the snap fastener 10, and the female snap fastener is sewn on both ends of the waist-cinching tie 9).

[0034] In this embodiment, reflective strips 12 are provided on the cuffs, outer side of the waist tie 9, shoulders, upper chest, and pant legs of the top 1. In dark spaces or relatively dark environments, the reflective light can form a 360° visible warning area, fully ensuring worker safety.

[0035] In this embodiment, a removable cushioning pad 13 is provided in the knee area of ​​the trouser body 2. The cushioning pad 13 is connected to the trouser body 2 via Velcro (the Velcro side is on the surface of the trouser body 2, and the Velcro side is at the rear of the cushioning pad 13 (not shown in the figure)). The cushioning pad 13 is filled with fire-retardant sponge. The removable cushioning pad 13, connected by Velcro, allows workers to flexibly replace or adjust the protection level according to actual working conditions. The fire-retardant sponge inside forms a heat-insulating cushioning layer in high-temperature environments, effectively absorbing the impact force when the knee comes into contact with hard objects, while blocking external heat from being conducted to the skin. Its modular design facilitates disassembly, cleaning, or replacement of damaged parts, significantly improving the maintenance efficiency and economy of the protective components.

[0036] In this embodiment, the trouser leg 2 is closed by a zipper structure 14, and a Velcro closure piece 15 is provided on the outer side of the trouser leg to adjust the tightness of the trouser leg. The combined design of the zipper closure structure and the Velcro closure piece 15 allows the trouser leg to fit tightly to the work boot, preventing metal shavings or sparks from entering through the gaps in the trouser leg. The outer Velcro closure piece 15 provides a graded tightness adjustment function (the Velcro closure piece 15 has a Velcro loop side, one end of which is sewn to the trouser leg, and the corresponding Velcro bar side is sewn to the other side of the trouser leg), adapting to different boot heights and leg circumference sizes. While ensuring airtightness, it avoids poor blood circulation caused by the trouser leg being too tight, thus balancing protective safety and wearing comfort.

[0037] In this embodiment, an accordion-style tool bag 16 is provided on the side of the trouser leg portion of the trouser body 2. The accordion-style tool bag 16 has multi-level stretchable pleats formed by folding the fabric on both sides. When closed, it is flush with the trouser surface. The accordion-style tool bag 16 dynamically adjusts its storage capacity by unfolding and closing the multi-level stretchable pleats: when the tool loading demand is large, the pleats unfold to expand the bag space; when there is no load or the work is in a confined space, the pleats close to keep the bag flat with the trouser surface and avoid snagging on surrounding equipment. This design solves the problem of low utilization or interference with movement caused by the fixed volume of traditional tool bags, and is especially suitable for ship maintenance scenarios that require frequent access to small tools.

[0038] In this embodiment, both the top 1 and the trousers 2 are made of aramid material and manufactured through a warp and weft interlacing process. The top 1 and trousers 2, made of aramid material through a warp and weft interlacing process, form a stable barrier against molten metal splashes through a high-density fiber interlacing structure. Its inherent flame-retardant properties allow for rapid carbonization upon high-temperature contact, delaying heat penetration. At the same time, the lightweight properties of aramid and the interlacing process give the clothing excellent breathability. While ensuring a slim fit, it significantly reduces the bulkiness and restriction of movement of traditional protective clothing, achieving a dual improvement in protective performance and operational flexibility.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
