Description

Technical Field

[0001] This utility model relates to the field of magic hook technology, and more specifically, it relates to a device for testing the degree of deformation of magic hooks. Background Technology

[0002] Magic hooks enable quick connection and separation through their physical structure. With their convenience of eliminating the need for traditional fasteners such as buttons and zippers, magic hooks are widely used in clothing, home furnishings, outdoor equipment, medical fields, and electronic devices.

[0003] Currently, under long-term use, if frequently subjected to external forces such as stretching, friction, or compression, the hook surface may experience hook breakage, fiber shedding, or deformation, leading to a gradual decrease in the adhesion and affecting the performance. Therefore, after the production of the magic hook is completed, it is necessary to test the degree of deformation of the magic hook and detect its deformation under pressure to ensure its production quality.

[0004] However, traditional testing methods often rely on manual observation and simple measuring tools. This approach is not only inefficient, but also makes it difficult to guarantee the accuracy and consistency of the measurement results. Since manual observation is easily affected by subjective factors, minute deformations may be overlooked. Furthermore, the accuracy of measuring tools is limited and cannot reflect the subtle deformation of the magic hook. Therefore, a magic hook deformation degree testing device is proposed to improve the existing problems. Utility Model Content

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: Example 1, see Figure 1 A magic hook deformation degree testing device includes a workbench 1, a detection component 3 is provided on the top of the workbench 1, a set of placement components 2 are provided on both sides of the detection component 3, and a magic hook 4 is provided below the placement components 2.

[0025] Specifically, two sets of placement components 2 are set up to place the magic hook 4 and apply corresponding pressure to the magic hook 4. After the magic hook 4 is pressed down by the placement components 2, the detection component 3 detects the magic hook 4, specifically the degree of deformation of the top left and right sides of the magic hook 4.

[0026] See Figure 2 and Figure 3 The placement component 2 includes a pressure block 28, and a placement seat 25 is provided below the pressure block 28. The detection component 3 is located on top of the placement seat 25.

[0027] See Figure 4 The detection component 3 includes a first mounting bracket 34, a first detection head 35 is provided at the bottom of the first mounting bracket 34, a second mounting bracket 36 is provided on one side of the first mounting bracket 34, and a second detection head 37 is provided at the bottom of the second mounting bracket 36. The detection component 3 is correspondingly provided at the bottom of the first detection head 35 and the second detection head 37.

[0028] The first detection head 35 and the second detection head 37 are both laser rangefinders, and both are externally connected to a computer processor. The laser emitting unit of the laser rangefinder emits a high-intensity, highly focused laser pulse. After the laser beam propagates in a straight line to the surface of the target object, part of the light is reflected to form an echo. The receiving unit of the sensor then captures this echo signal and processes the echo signal to obtain its distance. That is, the distance can be measured by the laser rangefinder. The height data measured by the first detection head 35 and the second detection head 37 can be transmitted to the computer processor for processing and analysis, thereby detecting the degree of deformation of the magic hook 4.

[0029] The first detection head 35 detects the degree of deformation at the first detection point, and the second detection head 37 detects the degree of deformation at the second detection point.

[0030] First, place the magic hook 4 on the placement seat 25, and then lower the pressure block 28 to a certain height. At this time, the magic hook 4 is restricted to a certain range, but the pressure block 28 does not apply pressure to the magic hook 4. Since all tests are conducted under the same conditions, the test results are reliable.

[0031] After the magic hook 4 is confined within a certain range by the pressure block 28, the first detection head 35 and the second detection head 37 are used to detect the first detection point and the second detection point, respectively. After the detection is completed, the detection data of the first detection head 35 is marked as A1 and the detection data of the second detection head 37 is marked as B1. After the pressure block 28 moves down and presses on the upper surface of the magic hook 4, the first detection head 35 and the second detection head 37 are used to detect the first detection point and the second detection point again. After the detection is completed, the detection data of the first detection head 35 is marked as A2 and the detection data of the second detection head 37 is marked as B2.

[0032] Based on the above test results, the numerical differences between A1 and B2, C1, D1, and D2 can be obtained. The data comparison is shown in Table 1.

[0033] Table 1: Comparison of Magic Hook Deformation Data The data comparison process is as follows: First, determine whether D1 meets the production standards. D1 can be used to visually determine whether there is severe deformation on the left and right sides in the initial state. If D1 does not meet the production standards, the deformation on the left and right sides can be determined, and targeted improvements can be made to the production process.

[0034] If D1 meets the production standards, the next step of testing is to apply pressure to the magic hook 4 and test the degree of deformation of the magic hook 4 under pressure. After applying pressure, C1 and C2 are judged respectively. The degree of deformation on the left and right sides can be directly judged by C1 and C2. If C1 and C2 do not meet the production standards, and D2 also does not meet the production standards, then there is a serious problem with one set of production processes for magic hook 4. The process with more problems can be improved in a targeted manner based on the overall process improvement. If C1 and C2 do not meet the production standards, but D2 meets the production standards, then the overall production process can be improved.

[0035] If only one of C1 and C2 fails to meet the production standards, the production process will be improved for the non-compliant group. If both C1 and C2 meet the production standards, the product is considered qualified and the process meets the production requirements.

[0036] By comparing the above methods, we can obtain the degree of overall deformation of the Magic Hook 4 and the degree of deformation on both the left and right sides. In the subsequent production process, we can make targeted improvements, such as adjusting the overall production process or improving the detailed structure of the production process on both the left and right sides. This provides good data support for improving the production process.

[0037] By setting the laser sampling of detection component 3, invisible minute deformations are transformed into quantifiable data. Finally, by comparing the data, the deformation results of one side and the whole are output, providing a clear direction for optimizing the production process.

[0038] See Figure 3 The placement component 2 also includes a first slide rail 21, a first slider 23 is slidably connected to one side of the first slide rail 21, and a lead screw 22 is provided through the top of the first slide rail 21.

[0039] See Figure 3 The bottom of the lead screw 22 is connected to the first slider 23, and the top of the lead screw 22 is provided with a rotating handle 26.

[0040] See Figure 3 The bottom of the first slider 23 is provided with a connecting seat 27, and the pressure block 28 is provided at the bottom of the connecting seat 27. The pressure block 28 and the connecting seat 27 are connected by bolts.

[0041] See Figure 3 A lifting mechanism 24 is provided on one side of the first slide rail 21, and a placement seat 25 is provided on the top of the lifting mechanism 24. Two sets of baffles 29 are symmetrically arranged on the top of the placement seat 25.

[0042] Specifically, restricting the movement direction of the first slider 23 ensures that the pressure block 28 applies force along a straight line when it moves down, reducing the problem of uneven pressure caused by the offset of the pressure block 28, stabilizing the force on the magic hook 4, and reducing deformation test errors caused by the offset of the applied force.

[0043] The lifting distance of the pressure block 28 can be controlled by rotating the handle 26, so as to achieve controllable adjustment of the initial position and pressure magnitude of the pressure application.

[0044] The side wall of the first slide rail 21 is provided with a scale, which can be adjusted according to the scale corresponding to the first slider 23 to reduce operation error and improve the accuracy of the descent of the pressure block 28.

[0045] Further adjustments to the rotating handle 26 make operation more convenient, requiring no complicated tools, reducing the difficulty of manual operation, improving testing efficiency, and reducing the random errors of manual adjustment.

[0046] The pressure block 28 and the connecting seat 27 can be connected by bolts. The adjusting connecting seat 27 serves as a transition connection, making the force transmission between the pressure block 28 and the first slider 23 stable. The bolts are detachable, which makes it convenient to replace the pressure block 28 with a suitable one according to different specifications of magic hook 4, thus improving the versatility of the device.

[0047] The lifting mechanism 24 includes a housing and a lifting cylinder, wherein the housing is sleeved on the outside of the lifting cylinder, and the output end of the lifting cylinder is connected to the placement seat 25. When the lifting cylinder is activated, the placement seat 25 can move vertically under the drive of the lifting cylinder.

[0048] During actual testing, the position of the placement seat 25 can be adjusted by the lifting cylinder, that is, the position of the magic hook 4 can be adjusted by the lifting cylinder. According to the testing standards, the magic hook 4 can be raised to a suitable height for testing according to its specifications, so that the magic hook 4 can be tested under a unified standard. In addition, the placement seat 25 can provide a flat and stable placement surface for the magic hook 4. The surface of the placement seat 25 is equipped with a rubber anti-slip pad to reduce the possibility of the magic hook 4 moving during the lifting process.

[0049] The height of the placement seat 25 can be flexibly adjusted by the lifting mechanism 24 to accommodate magic hooks 4 of different thicknesses, so that the relative position of the magic hook 4 and the pressure block 28 is reasonable.

[0050] The two sets of baffles 29 are connected to the placement seat 25 by bolts, and the baffles 29 can be adjusted according to the width of the magic hook 4.

[0051] The baffle 29 can reduce the left and right displacement of the magic hook 4 under pressure or during the detection process, so that the first detection point and the second detection point of the magic hook 4 are always aligned with the first detection head 35 and the second detection head 37.

[0052] See Figure 4The detection component 3 also includes a second slide rail 31, on one side of which a second slider 32 is slidably connected, and on one side of the second slider 32 a locking bolt 38 is provided.

[0053] See Figure 4 The second slider 32 is provided with a mounting base 33 on the side away from the second slide rail 31, and the first mounting bracket 34 and the second mounting bracket 36 are arranged on the mounting base 33 in sequence.

[0054] The second slider 32 can slide along the second slide rail 31. The first mounting bracket 34 and the second mounting bracket 36 are respectively connected to the mounting base 33 by bolts. According to the above adjustable method, the lateral position of the first detection head 35 and the second detection head 37 can be flexibly adjusted according to the width of the magic hook 4 and the detection point requirements, so as to adapt to the detection of different specifications of magic hook 4 and improve the versatility of the device.

[0055] The locking bolt 38 can fix the second slider 32 after the position is adjusted, which facilitates the adjustment of the position of the detection head.

[0056] In the actual testing process, firstly, the long strip-shaped sampling hook 4 is placed on the placement seat 25 and adjusted to the testing position by the lifting mechanism 24, so that the two ends of the long strip-shaped sampling hang down naturally. Then, a pressure block 28 of appropriate weight is selected, and the rotating handle 26 is started to slowly lower it and press it on the hook 4, so that the hook 4 is in a stretched state. Finally, the first detection head 35 detects the degree of deformation of the first detection point, the second detection head 37 detects the degree of deformation of the second detection point, and transmits the data to the computer for processing and analysis.

[0057] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
