Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, and in particular relates to a watch strap aging test device. Background Technology

[0002] The watch strap is an essential component of a watch, worn on the wearer's wrist. A wide variety of watch straps are available, including metal and rubber straps, allowing users to choose according to their preferences. Rubber straps, in particular, are popular among young people due to their lightweight and malleability. However, rubber is prone to aging due to its inherent properties. Therefore, during the manufacturing process, aging testing equipment is needed to conduct aging tests on rubber watch straps to meet testing requirements.

[0003] However, existing technologies have some problems: they do not have a UV aging test light source, and they cannot be rotated to allow the UV light source to irradiate during bending tests, thus failing to meet the requirements of comprehensive aging tests. Therefore, we propose a watch strap aging test device. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a watch strap aging test device. By incorporating an ultraviolet lamp and a structure that can bend the watch strap, the watch strap can simultaneously withstand two different aging tests, and the watch strap can be rotated to flip it over for ultraviolet irradiation.

[0005] This utility model is implemented as follows: a watch strap aging test device includes a housing, inside which a frame device is installed. The frame device includes a top plate, and two guide rails are fixedly connected to the lower part of the top plate. A bottom plate is welded to the lower part of the guide rails. The guide rails are connected to the housing via a rotating shaft. A stepper motor is fixedly connected to the right side of the housing, and the output shaft of the stepper motor is fixedly connected to the rotating shaft connecting the guide rails. A lifting plate is provided between the top plate and the bottom plate. Watch strap clamping devices are respectively installed on the lifting plate and the bottom plate. A door is connected to the housing, and an ultraviolet lamp is fixedly connected to the inside of the door. A cylinder for pushing the lifting plate is fixedly connected to the top plate.

[0006] Optionally, a spring mounting plate is fixedly connected to the upper part of the guide rail, and a return spring is connected between the spring mounting plate and the lifting plate.

[0007] Optionally, a magnetic strip is fixedly connected to the door, and a sheet metal is fixedly connected to the front of the box body.

[0008] Optionally, a thermometer is fixedly connected inside the box, and a protective film is affixed to the box door.

[0009] Optionally, a slider is fixedly connected to the end of the lifting plate, and the slider is slidably connected to the guide rail.

[0010] Optionally, the watch strap clamping device includes a lower plate, a first vertical plate and a second vertical plate are fixedly connected to the upper part of the lower plate, a first toothed plate is fixedly connected to the second vertical plate, a screw is threadedly connected to the first vertical plate, a second toothed plate is connected to the end of the screw through a bearing, and a handle is fixedly connected to one end of the screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By incorporating ultraviolet lamps within the enclosure, along with a structure that allows the watch strap to bend (such as a cylinder-driven lifting plate and strap clamps), and a design that allows the strap to flip within the enclosure's internal space, a combined mechanical fatigue and light aging test of the watch strap is achieved within the same device. This simulates various stress conditions that the watch strap might experience under actual wearing conditions, including but not limited to tension, bending, and material aging caused by long-term exposure to ultraviolet light. Ultimately, this device can simultaneously simulate the effects of mechanical stress and light aging, providing a more comprehensive assessment than a single testing method. The automation mechanism reduces the need for manual operation, minimizing errors caused by human factors and making the testing process more standardized. Strict control of the testing environment, such as temperature, humidity, and ultraviolet intensity, ensures consistent testing conditions for each test, thereby improving the comparability and reliability of test results. Users can easily start the testing program with simple settings and complete multiple rounds of testing without frequent intervention, saving time and labor costs.

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] like Figures 1 to 5 As shown in the figure, this utility model provides a watch strap aging test device.

[0022] The device includes a housing 1, inside which a frame assembly is installed. The frame assembly includes a top plate 3, with two guide rails 15 fixedly connected to the lower part of the top plate 3. A bottom plate 4 is welded to the lower part of the guide rails 15. The guide rails 15 are connected to the housing 1 via a rotating shaft. A stepper motor 8 is fixedly connected to the right side of the housing 1. The output shaft of the stepper motor 8 is fixedly connected to the rotating shaft connecting the guide rails 15. A lifting plate 13 is provided between the top plate 3 and the bottom plate 4. Watch strap clamping devices 9 are respectively installed on the lifting plate 13 and the bottom plate 4. The upper and lower watch strap clamping devices 9 are used to fix the two ends of the watch strap. A door 5 is connected to the housing 1. An ultraviolet lamp 6 is fixedly connected to the inside of the door 5. A cylinder 2 for pushing the lifting plate 13 is fixedly connected to the top plate 3.

[0023] A spring mounting plate 14 is fixedly connected to the upper part of the guide rail 15, and a return spring 12 is connected between the spring mounting plate 14 and the lifting plate 13.

[0024] A magnetic strip 7 is fixedly connected to the door 5, and a sheet metal 10 is fixedly connected to the front of the body 1.

[0025] A thermometer 11 is fixedly connected inside the box 1, and a protective film is affixed to the box door 5.

[0026] A slider is fixedly connected to the end of the lifting plate 13, and the slider is slidably connected to the guide rail 15.

[0027] The watch strap clamping device 9 includes a lower plate 92, a first vertical plate 97 and a second vertical plate 91 are fixedly connected to the upper part of the lower plate 92, a first toothed plate 93 is fixedly connected to the second vertical plate 91, a screw 95 is threadedly connected to the first vertical plate 97, a second toothed plate 94 is connected to the end of the screw 95 through a bearing, and a handle 96 is fixedly connected to one end of the screw 95.

[0028] This invention provides a watch strap aging test device. Its key innovation lies in the frame device installed inside the housing 1, including a top plate 3, a guide rail 15, and a bottom plate 4. A stepper motor 8 drives the guide rail 15 to rotate, and a cylinder 2 achieves the reciprocating motion of the lifting plate 13 between the top plate 3 and the bottom plate 4. This design utilizes the high-precision positioning characteristics of the stepper motor 8 to precisely control the rotation trajectory and frequency of the frame device, solving the problem of inconsistent and repeatable testing in traditional manual operation methods. This ensures that the testing conditions are the same each time, improving the reliability of the test results.

[0029] Specifically, the design cleverly utilizes a stepper motor 8 as a drive source, which is connected to the guide rail 15 via a rotating shaft, thereby enabling the guide rail 15 to rotate and making the illumination more uniform.

[0030] Cylinder 2 drives the lifting plate 13 between the top plate 3 and the bottom plate 4 to reciprocate. This design not only simplifies the mechanical structure, but also, due to the constraints of the guide rail 15 and the slider, allows for precise control of the strap's movement trajectory and frequency, making the testing process more controllable. Regarding the technical problem of ensuring consistent and repeatable testing using traditional manual operation methods, this invention effectively solves this problem, ensuring identical testing conditions for each test and improving the reliability of the test results.

[0031] In addition, a lifting plate 13 is provided between the top plate 3 and the bottom plate 4, and watch strap clamping devices 9 are respectively installed on the lifting plate 13 and the bottom plate 4. A cylinder 2 for pushing the lifting plate 13 is fixedly connected to the top plate 3. By pushing the lifting plate 13 with the cylinder 2, the watch strap can be bent at different positions, increasing the diversity and complexity of the test. Furthermore, compared with the traditional fixed test mode, this design can simulate various stress states of the watch strap in actual use, thereby more realistically reflecting the aging of the watch strap and improving the authenticity and effectiveness of the test.

[0032] Furthermore, an ultraviolet lamp 6 is fixedly connected to the inside of the door 5 connected to the housing 1. Placing the ultraviolet lamp 6 inside the door 5 not only facilitates lamp replacement and maintenance but also ensures that ultraviolet light is evenly distributed on the watch strap, accelerating its aging process. Existing testing methods often neglect the influence of light on material aging, while this design, by introducing the ultraviolet lamp 6, can accelerate the testing process and shorten the R&D cycle while simulating the natural environment. This design not only overcomes the shortcomings of traditional testing methods but also creatively proposes a new solution, which is of great significance for improving the accuracy and efficiency of watch strap aging tests.

[0033] In summary, through the design of the aforementioned key steps, this utility model not only overcomes the shortcomings of traditional testing methods but also creatively proposes a new solution, which is of great significance for improving the accuracy and efficiency of watch strap aging tests, demonstrating high technological innovation and practicality.

[0034] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
