Description

Technical Field

[0001] This utility model relates to an outer garment structure, and more particularly to an outer garment structure for a fall protection suit. Background Technology

[0002] A fall protection vest is a safety device that combines intelligent sensing technology with airbag protection. It is primarily used to reduce the impact of falls from heights or accidental falls, protecting critical parts of the body from serious injury. It generally consists of an airbag liner, an air cylinder, and an outer garment. Upon detecting a fall signal, the air cylinder quickly inflates the airbag, reducing the risk of injury. Fall protection vests are typically used in high-altitude work scenarios, such as substation equipment maintenance, building structure upkeep, and air conditioner outdoor unit installation. These environments are often harsh, and the vests are prone to wear and tear and dirt accumulation, requiring frequent replacement of the outer garment and impacting work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an outer garment structure for fall protection clothing. It reduces wear and tear on the outer garment and is easy to clean.

[0004] The technical solution of this utility model is as follows: A protective clothing outer garment structure includes an outer garment body, a safety zipper on the front side of the outer garment body, safety buckles on both sides of the safety zipper, a vertically arranged strip opening on the back side of the outer garment body, and reflective strips connected end to end on both the front and back sides of the outer garment body; the outer garment body includes a base layer, an expanded polytetrafluoroethylene (ePTFE) membrane layer on the outer side of the base layer, a breathable layer on the outer side of the ePTFE membrane layer, an abrasion-resistant layer on the outer side of the breathable layer, and an adhesive layer on the inner side of the base layer.

[0005] In the aforementioned outer garment structure of a fall protection suit, the upper and lower sides of the inner side of the outer garment body are provided with buttons for connecting to the inner liner of the fall protection suit's airbag.

[0006] In the aforementioned outer garment structure of a fall protection suit, the breathable layer is made of polyester fiber yarn woven using honeycomb knitting technology.

[0007] In the aforementioned outer garment structure of a fall protection suit, the abrasion-resistant layer is woven from yarn made of a blend of acrylic fiber and cotton fiber.

[0008] In the aforementioned outer garment structure of a fall protection suit, the bonding layer is woven from cotton thread and polyester fiber, and the inner side of the bonding layer is provided with evenly distributed strips.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] This application avoids damage to the application due to friction with the outside environment by setting a wear-resistant layer on the outermost side of the base layer. The wear-resistant layer has high toughness and can effectively resist scratches from sharp objects. The expanded polytetrafluoroethylene film layer can resist liquid water. In the event of dirt on the outside of the application, the wear-resistant layer can be cleaned directly with a cleaning agent, and water cannot penetrate into the inner side of the base layer.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example. An outer garment structure for a fall protection suit, configured as follows: Figure 1-3 As shown, the garment includes an outer garment body 1, a safety zipper 2 on the front side of the outer garment body 1, safety buckles 3 on both sides of the safety zipper 2, a vertically arranged strip opening 4 on the back side of the outer garment body 1, and reflective strips 5 connected end to end on both the front and back sides of the outer garment body 1; the outer garment body 1 includes a base layer 1.1, an expanded polytetrafluoroethylene (ePTFE) film layer 1.3 on the outside of the base layer 1.1, a breathable layer 1.5 on the outside of the ePTFE film layer 1.3, a wear-resistant layer 1.4 on the outside of the breathable layer 1.5, and an adhesive layer 1.2 on the inside of the base layer 1.1.

[0017] The outer garment body 1 has buttons 1.7 on the upper and lower sides inside for connecting with the inner liner of the fall protection suit airbag.

[0018] The breathable layer 1.5 is made of polyester fiber yarn woven using honeycomb knitting technology.

[0019] The wear-resistant layer 1.4 is woven from yarn made of a blend of acrylic fiber and cotton fiber.

[0020] The bonding layer 1.2 is woven from cotton thread and polyester fiber, and the inner side of the bonding layer 1.2 is provided with evenly distributed strips 1.6.

[0021] The principle of this utility model: This application is an outer garment for a fall protection suit. This application is connected to the airbag liner of the fall protection suit through a common button structure. That is, buttons 1.7 are set on the upper and lower sides inside the outer garment body 1, and the outer airbag liner is provided with a cloth strip corresponding to the buttons 1.7.

[0022] When wearing this garment, it is put on via a safety zipper 2 and fastened via a safety buckle 3. A vertically oriented strip opening 4 is provided on the back of the outer garment body 1 to cooperate with the airbag liner, that is, to provide deformation space when the airbag liner is inflated.

[0023] Fall protection vests are typically used for high-altitude equipment maintenance, wall upkeep, and equipment installation, environments where they are prone to wear and tear and soiling. The outermost layer of the outer garment body 1 in this application is an abrasion-resistant layer 1.4 woven from a blend of acrylic and cotton fibers, providing good abrasion resistance and toughness to prevent breakage from sharp objects. A breathable layer 1.5 is located inside the abrasion-resistant layer 1.4. This breathable layer 1.5 is woven from polyester yarn using a honeycomb knitting technique, providing good breathability and partially suspending the abrasion-resistant layer, which facilitates drying of the abrasion-resistant layer 1.4. The inner side of the breathable layer 1.5 is a expanded polytetrafluoroethylene (ePTFE) membrane layer 1.3 disposed on the base layer 1.1. ePTFE membrane is a unique microporous material with micropore diameters typically ranging from 0.1 to several micrometers. This gives ePTFE membrane excellent air and water permeability while effectively blocking the passage of liquids and particles. Because ePTFE membrane has poor abrasion resistance, it is disposed inside the abrasion-resistant layer in this application. Since this application is not frequently bent or rubbed, the ePTFE membrane layer 1.3 is less prone to damage. Furthermore, when the outer abrasion-resistant layer 1.4 becomes dirty, cleaning can be performed based on the degree of dirt accumulation. If the dirty area on the surface of the abrasion-resistant layer 1.4 is small, the surface can be cleaned directly with a cleaning agent. Since the ePTFE membrane 1.3 prevents liquid passage, this avoids compromising comfort, and the breathable layer 1.5 also improves the drying speed of the abrasion-resistant layer 1.4. The base layer 1.1 can be made of antibacterial materials, such as antibacterial silver ion fiber or bamboo charcoal fiber. The inner side of the base layer 1.1 has an adhesive layer 1.2, which can better fit with the inner airbag liner. The retaining strip 1.6 can fit with the airbag on the inner airbag liner for a more stable fit.
