Technical Field

[0001] This invention relates to the field of garment fabric testing technology, specifically to a device for testing the tensile strength of garment fabrics. Background Technology

[0002] Clothing is composed of three elements: style, color, and fabric. Among these, material is the most fundamental element. Clothing material refers to all materials that make up clothing, and can be divided into clothing fabrics and clothing accessories. The concept of clothing fabric specifically refers to the material that embodies the main characteristics of clothing.

[0003] When testing the tensile strength of clothing fabrics, it is necessary to go to a laboratory and find specialized instruments for testing.

A hydraulic telescopic mechanism is installed on the upper end of the protective box, and a moving plate is connected to the lower end of the hydraulic telescopic mechanism. The above device is large in size and cannot be transported to the site for testing, which delays the progress of the testing work.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 - Figure 4 A device for testing the tensile strength of clothing fabric includes a left outer ring 100 and a right outer ring 200. The centers of the left outer ring 100 and the right outer ring 200 are located at the same position. The outer surfaces of the left outer ring 100 and the right outer ring 200 are polished smooth to prevent damage to the clothing fabric. The bottoms of the left outer ring 100 and the right outer ring 200 are rotatably connected by a shaft for easy disassembly. Force sensors are evenly distributed on the outer surfaces of the left outer ring 100 and the right outer ring 200. The force sensors are of conventional structure; only compatible ones need to be found. The central inspection port 300 is located at the notch between the top of the left ring 100 and the right ring 200 of the outer cover, and the notch is formed by cutting. The power unit 400 is located between the left ring 100 and the right ring 200 of the outer casing; The middle detection structure 500 is connected to the output end of the power component 400, and its end is located at the middle detection port 300. A matching force sensor is provided at the top of the middle detection structure 500. The garment fabric is placed over the outer left ring 100 and outer right ring 200 of the outer cover. The power unit 400 and the central detection structure 500 are activated. The power unit 400 drives the outer left ring 100 and outer right ring 200 to rotate outward. The central detection structure 500 extends from the central detection port 300 to test the tensile strength data of various parts of the garment fabric. The central detection structure 500 can also be used alone to perform tension testing.

[0020] In use, the left outer ring 100 and the right outer ring 200 rotate together to fix the two ends of the garment fabric, and then are placed over the outside of the left outer ring 100 and the right outer ring 200. When performing tensile strength testing, the power assembly 400 and the central detection structure 500 are activated. The power assembly 400 extends and retracts, causing the left outer ring 100 and the right outer ring 200 to rotate outward, thereby bringing the outer sides of the left outer ring 100 and the right outer ring 200 into contact with the garment fabric. This allows the force sensors on the outer sides of the left outer ring 100 and the right outer ring 200 to detect data. Simultaneously, the left outer ring 100 and the right outer ring 200 rotate outward. The external rotation will extend the central detection structure 500 from the central detection port 300, contact the center of the garment fabric, and perform the test. The length of the central detection structure 500 can also be adjusted to test only the force on the outer fabric of the left outer ring 100 and the right outer ring 200 of the outer cover until the garment fabric breaks, thus obtaining tensile strength data. Alternatively, the central detection structure 500 can be used alone to test the tension of the garment fabric. When not in use, the power component 400 can be activated to return it to its initial position, making the structure easy to remove and allowing it to be tested on a real-world site.

[0021] Please see Figure 1 and Figure 3 The left ring 100 and the right ring 200 of the outer cover are symmetrically provided with sliding grooves 201 for sliding connection of the power component 400. The inside of the sliding grooves 201 is coated with lubricating oil to reduce friction. The power component 400 slides in the sliding grooves 201, causing the central detection structure 500 to extend out from the central detection port 300.

[0022] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The power assembly 400 includes a base structure 401 rotatably connected to the bottom of the left ring 100 and the right ring 200 of the outer casing, and: The sliding structure 402 is slidably connected to the slide groove 201, and the middle detection structure 500 is vertically fixed at the middle position of the sliding structure 402; The telescopic component 403 connects the base structure 401 and the sliding structure 402. The telescopic component 403 can be a hydraulic cylinder or a pneumatic cylinder, depending on the type and requirements of the garment fabric.

[0023] When in use, the power assembly 400 is activated, and the telescopic component 403 extends and retracts. The extension and retraction of the telescopic component 403 causes the base structure 401 to rotate downward, which in turn causes the sliding structure 402 to rotate upward on the slide groove 201. This causes the left ring 100 and the right ring 200 of the outer cover to rotate outward. As the left ring 100 and the right ring 200 of the outer cover rotate outward, the central detection structure 500 extends out from the central detection port 300.

[0024] Please see Figure 3 , Figure 6 , Figure 7 and Figure 8 The base structure 401 includes a fixing plate 401a vertically fixed to the bottom end of the telescopic member 403, the telescopic member 403 being fixed to the fixing plate 401a by screws, and: Fixing base 401b is symmetrically fixed at the bottom of the left ring 100 and the right ring 200 of the outer cover. Fixing base 401b is welded to the bottom of the left ring 100 and the right ring 200 of the outer cover. The connecting rod 401c is rotatably connected between the two ends of the fixed plate 401a and the fixed seat 401b.

[0025] During use, the telescopic component 403 extends and retracts. Due to the obstruction of the clothing fabric by the central detection structure 500, the telescopic component 403 cannot move towards the central detection port 300. Instead, it moves towards the fixed seat 401b. The telescopic component 403 drives the fixed plate 401a to move towards the fixed seat 401b, thereby causing the connecting rod 401c to press against the fixed seat 401b, causing the left ring 100 and the right ring 200 of the outer cover to rotate outward.

[0026] Please see Figure 3 , Figure 6 , Figure 7 and Figure 9 The sliding structure 402 includes a top plate 402a vertically fixed to the bottom end of the central detection structure 500, the central detection structure 500 being fixed to the top plate 402a by screws, and: Slider 402b is slidably connected to slide groove 201; Rotary transmission rod 402c is connected between the two ends of the top plate 402a and the slider 402b.

[0027] In use, the extension and retraction of the telescopic component 403 will cause the left ring 100 and the right ring 200 of the outer cover to rotate outward, and the slide 201 will rotate accordingly. The slider 402b slides upward relative to the slide 201. The extension and retraction of the telescopic component 403 is hindered by the clothing fabric, causing the top plate 402a to move towards the fixed plate 401a. In summary, the top plate 402a and the slider 402b drive the transmission rod 402c to rotate towards the telescopic component 403, thereby further driving the left ring 100 and the right ring 200 of the outer cover to rotate outward.

[0028] Among them, the outer side of the slider 402b is embedded with a roller to reduce friction.

[0029] Please see Figure 1 , Figure 3 and Figure 4 The bottom of the left ring 100 of the outer cover is fixed with a fixing component 600 for fixing the garment fabric, which facilitates the fixing of both ends of the garment fabric.

[0030] Please see Figure 1 , Figure 3 , Figure 4 and Figure 10 The fixing component 600 includes a fixing block 601 vertically fixed to the bottom end of the left ring 100 of the outer cover, the fixing block 601 being fixed to the bottom end of the left ring 100 of the outer cover by rivets, and: A protrusion 602 is vertically fixed to the bottom end of the fixing block 601, and the protrusion 602 is welded to the bottom end of the fixing block 601. The concave block 603 engages with the bottom end of the protrusion 602, and the contact surfaces of the protrusion 602 and the concave block 603 are adapted to each other; The fastening bolts 604 are rotatably connected to both ends of the protrusion 602 and fix the concave block 603 on the protrusion 602.

[0031] When using it, loosen the fastening bolt 604, fold the two ends of the garment fabric together and place them at the bottom of the protrusion 602, then close the concave block 603, and finally rotate the fastening bolt 604 so that the fastening bolt 604 is in the placement groove at both ends of the concave block 603, and then tighten it. It is simple and convenient to use.

[0032] The contact surfaces of both the protrusion 602 and the concave block 603 are provided with barbs to increase the reliability of the garment fabric.

[0033] The central detection structure 500 is a telescopic component. This application uses a cylinder or a hydraulic cylinder to facilitate the telescopic movement and detection of the central detection structure 500.

[0034] Working principle: Initially, the left outer ring 100 and the right outer ring 200 are close to each other. First, the garment fabric is placed over the outside of the left outer ring 100 and the right outer ring 200, with both ends of the fabric placed at the bottom of the protrusion 602. The concave block 603 and the protrusion 602 are then secured together using the fastening bolt 604. When performing tensile strength testing, the telescopic component 403 and the central detection structure 500 are activated. Because the central detection structure 500 is obstructed by the garment fabric, the telescopic component 403 cannot extend towards the center. The detection port 300 moves, thus moving towards the fixed seat 401b. The telescopic component 403 drives the fixed plate 401a to move towards the fixed seat 401b, thereby causing the connecting rod 401c to press against the fixed seat 401b, causing the left ring 100 and right ring 200 of the outer cover to rotate outward. This rotation causes the slide groove 201 to rotate accordingly, while the slider 402b slides upward relative to the slide groove 201. The telescopic component 403's extension and retraction are influenced by the clothing fabric. The obstruction causes the top plate 402a to move towards the fixed plate 401a. Combined, the top plate 402a and the slider 402b drive the transmission rod 402c to rotate towards the telescopic component 403, thereby further driving the left outer ring 100 and the right outer ring 200 of the outer cover to rotate outwards. This causes the outer sides of the left outer ring 100 and the right outer ring 200 to contact the clothing fabric, allowing the force sensors on the outer sides of the left outer ring 100 and the right outer ring 200 to detect data. Simultaneously, the outward rotation of the left outer ring 100 and the right outer ring 200... The central detection structure 500 extends from the central detection port 300, contacts the center of the garment fabric, and performs the test. Alternatively, the length of the central detection structure 500 can be adjusted to test only the fabric force on the outer left ring 100 and the outer right ring 200 of the outer cover until the garment fabric breaks, thus obtaining tensile strength data. The central detection structure 500 can also be used alone to perform tension testing on the garment fabric. When not in use, the telescopic component 403 can be activated to return to the initial position.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
