Description

Technical Field

[0001] This utility model relates to a test for the folding resistance of a hat brim, and more particularly to a test device for the folding resistance of a hat brim. Background Technology

[0002] As a common clothing accessory that combines functionality and aesthetics, the physical durability of the brim is crucial for hats. During daily use, the brim frequently undergoes bending, such as manual adjustments when wearing, folding and squeezing during storage, or repeated opening and closing in adjustable designs. These continuous mechanical stresses can easily lead to irreversible damage to the brim, manifesting as permanent deformation, fracture of the internal support structure, peeling of the surface coating or damage to decorative finishes, and loosening or unraveling of the seams connecting it to the hat body. Such damage not only directly affects the product's functionality (such as sun protection and shaping effect) but also severely weakens the product's aesthetic integrity and brand value.

[0003] Current methods for evaluating the folding resistance of hat brims have significant limitations. Traditional methods, relying on manual, repeated bending and subjective visual judgment, are inefficient. Test results are easily affected by variations in the operator's force, angle, and rhythm, lacking quantitative standards and comparability. While using simple clamps to assist testing in some cases provides a slight improvement, it still struggles to precisely control core parameters such as bending stroke, angle, and frequency, failing to effectively simulate the complex stress states under real-world usage scenarios. Furthermore, the market lacks standardized, automated testing equipment specifically designed for the structural characteristics of hat brims (such as irregular curvature and internal supports). General-purpose material testing machines face difficulties in clamping samples and simulating specific bending patterns, making it challenging to provide scientifically objective evaluation data.

[0004] Therefore, it is necessary to improve an existing hat brim folding resistance testing device to solve the above problems. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a hat brim folding resistance testing device, aiming to solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hat brim folding resistance testing device, comprising: a base, a driving mechanism disposed on the base, and a testing mechanism disposed on one side of the driving mechanism.

[0007] The drive mechanism includes a drive base, an active component disposed on the drive base, and a driven component disposed on the drive base; the driven component is used to drive the experimental mechanism to reciprocate to perform test experiments.

[0008] The testing mechanism includes a testing chamber and an experimental component disposed within the testing chamber; the experimental component is used to clamp and repeatedly bend both ends of the brim, and the experimental component is fixedly connected to the driven component.

[0009] In a preferred embodiment of this utility model, the base is a rectangular base.

[0010] In a preferred embodiment of this utility model, the active component includes an active motor and a moving frame; a threaded rod is rotatably connected in the middle of the moving frame, and synchronous pulleys are fixedly connected to both the threaded rod and the active motor, and the synchronous pulleys are connected by a synchronous belt.

[0011] In a preferred embodiment of the present invention, the driven component includes a push plate and a push rod fixedly connected to the push plate. The push plate is slidably connected to the movable frame. The push plate is arranged in an inverted T-shape and engages with the threaded rod.

[0012] In a preferred embodiment of this utility model, a push rod is fixedly connected to one side of the push plate, the push rod passes through the test chamber, and the push rod is fixedly connected to the test component.

[0013] In a preferred embodiment of this utility model, the experimental components include a fixed frame and an experimental plate disposed on the fixed frame. The experimental plate is used to clamp the brim of the hat and perform repeated bending experiments.

[0014] In a preferred embodiment of this utility model, the fixing frame includes two fixing rods, the two ends of which are fixedly connected to the inside of the test chamber, and the test plate is disposed on the fixing rods.

[0015] In a preferred embodiment of this utility model, the experimental plate is arranged in an inverted T-shape. The experimental plate includes a fixed plate and a movable plate. The fixed plate is located on the side away from the push plate, and the movable plate is located on the side closer to the push plate.

[0016] In a preferred embodiment of this utility model, a fixing groove is provided on the top of both the fixing plate and the experimental plate, and a fixing member is provided in the fixing groove.

[0017] In a preferred embodiment of the present invention, the fixing member includes a clamping plate and a clamping rod rotatably connected to the clamping plate; the clamping rod is threadedly connected to the side wall of the fixing groove, and the clamping plate is slidably connected to the inside of the fixing groove.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a hat brim folding resistance testing device. The threaded rod is driven to rotate by the precise control of the servo motor, which drives the push plate to slide on the moving frame, realizing the controllable reciprocating motion of the push plate and the push rod. This design utilizes the mechanical efficiency of the threaded rod to optimize the energy transfer path, directly reducing the energy loss of the moving parts and improving the displacement accuracy. Existing technologies are simple electric push rods that lack precise adjustment functions. This solution overcomes the problems of discontinuous motion or large control errors, further realizes the repeatable setting of automated bending test, improves test efficiency, and can accurately simulate the bending frequency in the actual use environment.

[0020] (2) This utility model provides a hat brim folding resistance testing device. A clamping rod is threadedly connected to the side wall of the fixing groove and rotatably connected to the clamping plate. When the clamping rod is rotated, it pushes the clamping plate against the side wall of the fixing groove to form a clamping force, reliably fixing both ends of the hat brim. This design utilizes the characteristics of threaded transmission to ensure that the clamping force does not loosen during high-speed reciprocating motion, directly avoiding test interruptions caused by brim slippage or loosening. Compared to the spring-pressing method in existing clamping technologies, which is prone to failure due to vibration, this solution enhances the continuity of the test. A further effect is improved comparability of folding resistance data, reducing human error through uniform force application, and providing a standardized basis for large-scale product quality control.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] As shown in the figure, a hat brim folding resistance testing device includes: a base 1, a drive mechanism 2 disposed on the base 1, and a testing mechanism 3 disposed on one side of the drive mechanism 2.

[0027] The drive mechanism 2 includes a drive base 20, an active component 21 disposed on the drive base 20, and a driven component 22 disposed on the drive base 20; the driven component 22 is used to drive the experimental mechanism to reciprocate to perform test experiments; the base 1 is a rectangular base.

[0028] The test mechanism 3 includes a test chamber 30 and an experimental component 31 disposed in the test chamber 30; the experimental component 31 is used to clamp and repeatedly bend the two ends of the brim, and the experimental component is fixedly connected to the driven component 22.

[0029] It should be noted that both the test mechanism 3 and the drive mechanism 2 are fixedly connected to the base 1, which is a rectangular base. The drive mechanism 2 is located on one side of the test mechanism 3. The drive mechanism 2 is used to drive the test mechanism 3 to reciprocate. The test mechanism 3 is used to clamp the brim and drive the test mechanism 3 to reciprocate through the drive mechanism 2, thereby performing a bending test on the brim.

[0030] The drive mechanism 2 includes a drive base 20, an active component 21 disposed on the drive base 20, and a driven component 22 disposed on the drive base 20; the driven component 22 is used to drive the experimental mechanism to reciprocate to perform test experiments; the base 1 is a rectangular base.

[0031] In this invention, the active component 21 includes an active motor 23 and a moving frame 26; a threaded rod 27 is rotatably connected in the middle of the moving frame 26, and synchronous pulleys 24 are fixedly connected to both the threaded rod 27 and the active motor 23, and the synchronous pulleys 24 are connected by a synchronous belt 25; the driven component 22 includes a push plate 28 and a push rod 29 fixedly connected to the push plate 28, the push plate 28 is slidably connected to the moving frame 26, the push plate 28 is arranged in an inverted T shape, and the push plate 28 meshes with the threaded rod 27; a push rod 29 is fixedly connected to one side of the push plate 28, the push rod 29 is arranged through the test chamber 30, and the push rod 29 is fixedly connected to the experimental component 31.

[0032] It should be noted that the drive base 20 is fixedly connected to one side of the experimental chamber. The active component 21 and the driven component 22 are both located above the drive base 20. The active component 21 includes an active motor 23 and a moving frame 26. The moving frame 26 consists of only two rectangular plates and two connecting shafts. The connecting shafts are specifically round shafts. The two connecting shafts are fixedly connected to the two ends of the two rectangular plates respectively, as shown in the attached figure, thus forming a square frame. The square frame is the moving frame 26. The threaded rod 27 is rotatably connected to the middle position of the moving frame 26. One end of the threaded rod 27 passes through the moving frame 26. The active motor 23 is a servo motor. The active motor 23 is fixedly connected to the drive base 20. The active motor 23 and the threaded rod 27 are both fixedly connected to the synchronous pulleys 24 through the end of the moving frame 26. The two synchronous pulleys 24 are connected by a synchronous belt 25. Thus, the rotation of the active motor 23 drives the rotation of the threaded rod 27.

[0033] The driven component 22 includes a push plate 28 and a push rod 29. The push plate 28 is inverted T-shaped. The two ends of the bottom of the push plate 28 are slidably connected to the circular shaft of the moving frame 26. At the same time, a threaded hole is provided at the overlap between the horizontal and vertical parts of the push plate 28. The threaded hole engages with the threaded rod 27. In this way, when the drive motor 23 rotates, the threaded rod 27 is driven to rotate and the connecting rods on both sides of the moving frame 26 are limited, so that the threaded rod 27 drives the push plate 28 to move. As the drive motor 23 reciprocates, it drives the push plate 28 to move back and forth, which in turn drives the push rod 29, which is fixedly connected to the push plate 28, to move back and forth.

[0034] In a preferred embodiment of the present invention, the experimental component 31 includes a fixing frame 32 and an experimental plate disposed on the fixing frame 32. The experimental plate is used to clamp the brim of the hat and perform repeated bending experiments.

[0035] In a preferred embodiment of this utility model, the fixing frame 32 includes two fixing rods, the two ends of which are fixedly connected to the inside of the test chamber 30, and the test plate is disposed on the fixing rods.

[0036] In a preferred embodiment of the present invention, the experimental plate is arranged in an inverted T-shape. The experimental plate includes a fixed plate 33 and a movable plate 34. The fixed plate 33 is located on the side away from the push plate 28, and the movable plate 34 is located on the side close to the push plate 28.

[0037] In a preferred embodiment of this utility model, both the top of the fixing plate 33 and the experimental plate are provided with fixing grooves, and fixing components are provided in the fixing grooves.

[0038] In a preferred embodiment of the present invention, the fixing member includes a clamping plate 35 and a clamping rod 36 rotatably connected to the clamping plate 35; the clamping rod 36 is threadedly connected to the side wall of the fixing groove, and the clamping plate 35 is slidably connected to the inside of the fixing groove.

[0039] It should be noted that the test mechanism 3 includes a test chamber 30 and an test component 31. The test component 31 is located inside the test chamber 30 and is used to perform bending tests on the brim. The test component 31 includes a fixing frame 32 and a test plate. The fixing frame 32 consists of two fixing rods, which are cylindrical in shape and fixedly connected to the test chamber 30 at both ends. The test plate also has two components: a fixed plate 33 and a movable plate 34. The fixed plate 33 and the movable plate 34 have the same structure, but their connection to the fixing rods and their positions are different. The fixed plate 33 is fixedly connected to the fixing rod and is located at the end away from the push plate 28. The movable plate 34 is slidably connected to the fixed rod and is located at the end closer to the push plate 28. One end of the push rod 29 is fixedly connected to the push plate 28, and the other end is set through the test chamber 30 and fixedly connected to the bottom of the movable plate 34. This allows the movable plate 34 to move on the fixed rod during the back-and-forth movement of the push rod 29. When the push rod 29 moves to the end of the threaded rod 27, it simultaneously causes the adjacent sides of the movable plate 34 and the fixed plate 33 to come into contact. Fixed grooves are provided on both the fixed plate 33 and the movable plate 34. A threaded hole is provided on one side of the fixed groove. A clamping plate 35 is slidably connected in the fixed groove and engages with the clamping rod 36 in the threaded hole on the fixed groove. A threaded groove is provided on the clamping rod 36. The clamping rod 36 is rotatably connected to the clamping plate 35, so that the clamping plate 35 is pushed to come into contact with the side wall of the fixed groove during the rotation of the clamping rod 36.

[0040] During operation, before the start of the test experiment, the clamping rod 36 is rotated to push the clamping plate 35 and the side wall of the fixing groove to fit together. Then, the clamping plate 35 on the fixed plate 33 and the side wall of the fixing groove and the movable plate 34 clamp the front and rear ends of the brim. Then, the reciprocating motion of the active motor 23 drives the threaded rod 27 to rotate forward and backward, which in turn drives the push plate 28 to move back and forth. In this way, the push rod 29 on the push plate 28 drives the movable plate 34 to move back and forth, so that the movable plate 34 and the fixed plate 33 move relative to each other. The two ends of the brim are fixed on the fixed plate 33 and the movable plate 34. In this way, the relative movement of the movable plate 34 and the fixed plate 33 is used to perform multiple reciprocating bending tests on the brim to test its bending resistance.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
