[0029] In this embodiment, the test fixture base 1 serves as the core basic component. Its bottom is tightly connected to the vibration testing equipment via a sturdy base plate 2, ensuring high stability throughout the testing process and accuracy of the test results. The meticulously designed circular groove 3 on the test fixture base 1 not only provides precise positioning space for the main body 17 of the electronic device, but also further enhances the stability of the device placement and the convenience of subsequent rapid fixation through three triangularly distributed slots 4 on its inner wall. The fixture frame 5, as a detachable innovative design, perfectly matches the test fixture base 1. The three assembly blocks 6 installed on it are each fixed with a positioning rod 7. These positioning rods 7 can accurately pass through the flange reserved holes of the electronic device body 17 and be firmly inserted into the slot 4, achieving a fast and stable fixing effect, completely eliminating the tedious and time-consuming traditional bolt tightening. In addition, the ingenious design of the positioning mechanism further strengthens the connection between the fixture frame 5 and the test fixture base 1, ensuring that the electronic device body 17 remains motionless during strong vibration testing, effectively avoiding displacement or damage caused by vibration, thereby improving the accuracy and reliability of the test. The installation process is simple and efficient: First, the base plate 2 is firmly installed on the vibration... The electronic device body 17 is then precisely placed into the circular groove 3 of the test fixture base 1, with the flange hole aligned with the slot 4. Next, the fixture frame 5 is picked up and its positioning rod 7 is aligned with the pre-drilled hole on the flange of the electronic device body 17, allowing it to be smoothly inserted into the slot 4. Finally, the positioning mechanism is used to lock the fixture in place. The entire installation process is quick and effortless. Compared to traditional bolt fastening methods, this invention's quick-release fixture, with its unique insertion and locking mechanism, significantly shortens installation time and reduces the burden on operators. It is particularly suitable for R&D and testing environments where test pieces need frequent replacement, effectively overcoming the bottleneck of installation efficiency. Simultaneously, the triangularly distributed positioning rod design not only simplifies the installation steps but also provides strong stability during vibration testing, ensuring accurate test results. The detachable fixture frame design gives the test fixture greater flexibility and convenience, facilitating rapid replacement and maintenance of test pieces, and improving the overall utilization rate and work efficiency of the testing equipment.

[0030] The positioning mechanism includes: square tubes 9 symmetrically fixed on both sides of the test fixture base 1, with a pull-out detachable toothed plate 8 inside the square tubes 9, the toothed plate 8 being fixedly connected to the fixture frame 5; toothed blocks 10 vertically slidably mounted on the square tubes 9, the toothed blocks 10 achieving positioning by meshing with the toothed plate 8; a fixing frame 11 fixed on the square tubes 9, with a mounting frame 12 slidably mounted on the fixing frame 11, the bottom end of the mounting frame 12 being fixedly connected to the toothed blocks 10; and a spring 13 sleeved on the mounting frame 12.

[0031] In this embodiment, the positioning mechanism is ingeniously and efficiently designed. Its core lies in the square tube 9 structure symmetrically fixed to both sides of the test fixture base 1. This layout not only significantly enhances the overall structural stability but also lays a solid foundation for subsequent rapid and accurate positioning and stable locking. The square tube 9 is internally equipped with a pull-out, detachable toothed plate 8, which is securely connected to the side of the fixture frame 5. This toothed plate 8 serves as a precise positioning reference when needed, ensuring the accuracy of the positioning of the fixture frame 5. It can also be easily separated from the fixture frame 5 during disassembly, allowing the fixture frame 5 to be separated from the test fixture base 1, greatly improving the flexibility and convenience of use. Furthermore, slidable toothed blocks 10 are vertically mounted on the upper surface of the square tube 9. These toothed blocks 10, through a precise meshing mechanism with the toothed plate 8, achieve a seamless and stable connection between the fixture frame 5 and the test fixture base 1. When the toothed block 10 slides smoothly under external force until it fully and tightly engages with the toothed groove of the toothed plate 8, the fixture frame 5 is firmly locked onto the test fixture seat 1, thus ensuring that the main body 17 of the electronic device remains stationary during vibration testing, maintaining the stability and reliability of the test. To achieve precise control over the up-and-down sliding of the toothed block 10, this embodiment cleverly fixes a fixing frame 11 on the square tube 9 and slides a mounting frame 12 on it. The bottom end of the mounting frame 12 is tightly fixed to the toothed block 10. Therefore, when the operator applies an upward force to the mounting frame 12, it can smoothly drive the toothed block 10 to slide upward, while compressing the spring 13 sleeved on the mounting frame 12. Subsequently, the operator can easily pull out the toothed plate 8, thereby achieving quick disassembly of the fixture frame 5. The entire operation process is smooth and labor-saving, greatly improving the maintenance efficiency and usage flexibility of the test fixture.

[0032] The bottom inner wall of the square tube 9 is embedded with ball bearings 14 for guiding the toothed plate 8, and the ball bearings 14 are in contact with the bottom of the toothed plate 8.

[0033] In this embodiment, the ball bearing 14 is embedded in the bottom inner wall of the square tube 9 and can directly contact the bottom of the toothed plate 8. This design reduces the friction of the toothed plate 8 during the pulling process, making the movement of the toothed plate 8 smoother. As a rolling element, the ball bearing 14 can provide low-friction rolling support when the toothed plate 8 moves. This not only improves the smoothness of the pulling of the toothed plate 8, but also reduces wear during long-term use and extends its service life.

[0034] The base plate 2 has symmetrically arranged assembly holes 15 for inserting bolts to connect and fix it to the vibration testing equipment.

[0035] In this embodiment, the symmetrical design of the mounting hole 15 ensures the balance and symmetry when the base plate 2 is connected to the vibration testing equipment. The test fixture is firmly fixed to the vibration testing equipment by bolts passing through the mounting hole 15.

[0036] A pull ring 16 is fixedly installed on the top of the mounting bracket 12, which can be used to pull the mounting bracket 12 upward to compress the spring 13.

[0037] In this embodiment, the pull ring 16 is fixedly installed on the top of the mounting bracket 12, providing the operator with a direct point of force application. By holding the pull ring 16 and pulling it upward, the spring 13 can be easily compressed, thereby separating the tooth block 10 from the toothed plate 8 and unlocking the clamp bracket 5.

[0038] The top of the square tube 9 is provided with a mounting hole, which is adapted to the toothed block 10.

[0039] In this embodiment, the precise design of the mounting hole ensures the accurate sliding of the toothed block 10 in the vertical direction. This fit not only ensures the precise meshing between the toothed block 10 and the toothed plate 8, but also matches the size of the mounting hole with the toothed block 10, avoiding the toothed block 10 from shaking or deviating during the sliding process, thus ensuring the smoothness and accuracy of the entire positioning process.

[0040] The fixing frame 11 has a sliding opening, which is adapted to the mounting frame 12.

[0041] In this embodiment, the precise design of the sliding opening ensures the smoothness and stability of the mounting bracket 12 when it slides on it. The size of the sliding opening matches the mounting bracket 12, avoiding jamming or loosening during the sliding process and ensuring the continuity and consistency of operation.

[0042] In summary, the stable connection between the base plate 2 and the vibration testing equipment, along with the positioning rod 7 on the fixture frame 5, ensures the rapid and stable fixation of the electronic device body 17, eliminating the cumbersome and time-consuming traditional bolt fixing method and greatly improving installation efficiency. The positioning mechanism ensures a seamless and stable connection between the fixture frame 5 and the test fixture seat 1, so that the electronic device body 17 can maintain a stable position even during strong vibration testing, improving testing accuracy. The pull-out design of the toothed plate 8 and the addition of the ball bearing 14 enable smooth pull-out operation, reduce wear, extend service life, and also facilitate the quick disassembly and maintenance of the fixture frame 5.
