[0028] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0029] like Figures 1-6 As shown, the electronic device vibration test fixture with adjustable detection angle in this embodiment includes: a fixture body, which is composed of a base 1 and a mounting base 2, the mounting base 2 being hinged to the top of the base 1; a mounting groove 3 for mounting electronic devices on one side of the mounting base 2, the mounting groove 3 having multiple fixing bolts 4 threaded inside; an adjustment groove 7 on the bottom of the mounting base 2, the top of the adjustment groove 7 being inclined from the back side of the mounting base 2 to one side of the mounting groove 3; a pressure rod 11 slidably disposed on the top of the base 1 for adjusting the tilt angle of the mounting base 2, the top end of the pressure rod 11 contacting the top of the adjustment groove 7; and a drive mechanism disposed on the base 1 for driving the pressure rod 11 to slide.
[0030] In this embodiment, when the test angle of the electronic device needs to be adjusted, the driving mechanism is operated to make the pressure rod 11 slide in a certain direction on the base 1. The top end of the pressure rod 11 contacts the inclined surface of the adjustment groove 7 and applies pressure. As the pressure rod 11 moves, the mounting base 2 is subjected to torque and rotates around its hinge point with the base 1. The rotation of the mounting base 2 causes the electronic device mounted on it to change its tilt angle accordingly, thereby realizing the adjustment of the test angle. During adjustment, the support rod 18 rotates along the base 1 at the same time, causing the top end of the support rod 18 to drive the guide. Block 17 slides along guide rod 16. After adjusting to the required angle, guide block 17 is fixed by threaded rod 21, thereby stabilizing mounting base 2 and allowing vibration testing. The adjustable mounting base 2 and the pressure rod 11 enable flexible adjustment of the test angle of the fixture body, meeting different testing needs. The fastening bolt 4 allows it to pass through the hole in the electronic device during use, thus fixing it in the mounting groove 3. This ensures that the electronic device will not loosen or shift during testing, thereby improving the accuracy and reliability of the test results.
[0031] In a further preferred embodiment of the present invention, the top of the base 1 is provided with a plurality of threaded holes 5, and a connecting bolt 6 is threadedly installed in each of the plurality of threaded holes 5, and the top end of the pressure rod 11 is semi-circular.
[0032] In this embodiment, when adjusting the tilt angle of the mounting base 2, the push rod 11 is pushed to slide along the top of the base 1 by the drive mechanism. Due to the semi-circular design of the top of the push rod 11, it can slide more smoothly along the inclined surface of the adjustment groove 7. At the same time, the base 1 and the vibration table of the test electronic device are fastened together by the connecting bolt 6, ensuring the stability of the fixture body during the test.
[0033] In a further preferred embodiment of this utility model, the driving mechanism includes: a sliding groove 8 formed on the top of the base 1, the sliding groove 8 being located below the adjusting groove 7; a one-way screw 9 rotatably installed in the sliding groove 8; a slider 10 threaded onto the one-way screw 9, the top of the slider 10 being fixedly connected to the bottom end of the pressing rod 11; a connecting groove 12 formed in the base 1, one end of the one-way screw 9 extending into the connecting groove 12; a rotating rod 13 rotatably installed in the connecting groove 12, one end of the rotating rod 13 extending out of the base 1; and a set of bevel gears 14 respectively fixedly sleeved on the rotating rod 13 and the one-way screw 9, the set of bevel gears 14 meshing with each other.
[0034] In this embodiment, when the user needs to adjust the tilt angle of the mounting base 2, he / she only needs to rotate the rotating rod 13 extending out of the base 1. The rotation of the rotating rod 13 is transmitted to the one-way screw 9 through the meshing action of the bevel gear 14, so that the one-way screw 9 rotates in the slide groove 8. Since the slider 10 is threaded on the one-way screw 9, the slider 10 will move along the slide groove 8 as the one-way screw 9 rotates. The slider 10 drives the pressing rod 11 to slide at the same time, so that the top of the pressing rod 11 slides along the inclined surface of the adjustment groove 7, thereby changing the tilt angle of the mounting base 2. The setting of the one-way screw 9 ensures that a stable pushing force can be maintained during the adjustment process, avoiding the problem of inaccurate adjustment caused by poor sliding or loosening.
[0035] In a further preferred embodiment of the present invention, a guide groove 15 is provided on one side of the mounting base 2, a guide rod 16 is fixedly installed in the guide groove 15, a guide block 17 is slidably installed on the guide rod 16, a support rod 18 is hinged to one side of the guide block 17, and the bottom end of the support rod 18 is hinged to the base 1.
[0036] In this embodiment, when the tilt angle of the mounting base 2 is adjusted by the drive mechanism, the mounting base 2 will rotate around its hinge point with the base 1. At this time, the guide block 17 will slide along the guide rod 16, and the support rod 18 will swing with the rotation of the mounting base 2. Since the two ends of the support rod 18 are hinged to the guide block 17 and the base 1 respectively, it can provide continuous support force during the rotation of the mounting base 2, preventing the mounting base 2 from shaking or tilting due to uneven force. The support rod 18 provides support force to the mounting base 2, which helps to maintain its balance and stability at different tilt angles.
[0037] In a further preferred embodiment of the present invention, a bracket 19 is fixedly installed on one side of the guide block 17, and a screw rod 20 is slidably provided on the bracket 19. A threaded rod 21 is installed at one end of the screw rod 20, and the threaded rod 21 is threadedly connected to the guide block 17. One end of the threaded rod 21 is in contact with the guide rod 16.
[0038] In this embodiment, after adjusting the tilt angle of the mounting base 2, the screw rod 20 is rotated, causing the screw rod 20 to drive the threaded rod 21 to rotate, so that the threaded rod 21 is screwed into the guide block 17, and one end of the threaded rod 21 contacts the guide rod 16, thereby fixing the position of the guide block 17, ensuring that the support rod 18 is stable, and facilitating the limiting operation of the mounting base 2.
[0039] In a further preferred embodiment of the present invention, a connecting box 22 is installed on one side of the base 1. The connecting box 22 is rotatably connected to the rotating rod 13. A connecting gear 23 is fixedly sleeved on the rotating rod 13. A positioning block 24 located on one side of the connecting gear 23 is provided inside the connecting box 22. The positioning block 24 is engaged on the teeth of the connecting gear 23.
[0040] In this embodiment, when the user needs to adjust the tilt angle of the mounting base 2, the positioning block 24 is first pulled out, disengaging it from the teeth of the connecting gear 23. At this time, the rotating rod 13 can rotate freely, and the mounting base 2 is driven by the drive mechanism to adjust the tilt angle. After adjusting to the required angle, the user re-engages the positioning block 24 into the teeth of the connecting gear 23 to lock the rotation position of the rotating rod 13. In this way, the mounting base 2 is fixed at the current tilt angle and will not rotate unexpectedly during vibration testing. Simply inserting and removing the positioning block 24 can lock or release the rotation position of the rotating rod 13, greatly simplifying the operation steps and improving work efficiency.
[0041] In a further preferred embodiment of this utility model, a pull rod 25 is slidably installed on one side of the connecting box 22. One end of the pull rod 25 located inside the connecting box 22 is fixedly connected to the positioning block 24. A return spring 26 is sleeved on the pull rod 25. The two ends of the return spring 26 are in contact with the positioning block 24 and the inner wall of the connecting box 22, respectively. A support block 27 is installed on one side of the connecting box 22. A lever 28 is slidably installed on the support block 27. A limit block 29 is installed at the bottom end of the lever 28. Two limit grooves 30 are opened at the top of the pull rod 25. Both limit grooves 30 are adapted to the limit blocks 29.
[0042] In this embodiment, when the tilt angle of the mounting base 2 needs to be adjusted, the user first moves the lever 28 to disengage the limiting block 29 from the limiting groove 30 of the pull rod 25. Then, the user pulls the pull rod 25 to retract the return spring 26, causing the pull rod 25 to disengage the fixed positioning block 24 from the teeth of the connecting gear 23. After that, the limiting block 29 is inserted into the limiting groove 30 to fix the pull rod 25. Subsequently, the user can freely rotate the rotating rod 13 to adjust the tilt angle of the mounting base. After the adjustment is completed, the user pulls the lever 28, the return spring 26 is released, and the positioning block 24 is pushed back to its initial position and inserted into the teeth of the connecting gear 23, thereby locking the rotation position of the rotating rod 13. Through the coordinated action of the pull rod 25, the return spring 26, and the lever 28, smooth control of the rotation position of the positioning block 24 and the rotating rod 13 is achieved.
[0043] In summary, compared with related technologies, this device has the advantage of being able to quickly adjust the tilt angle of the mounting base 2, thereby meeting different testing requirements.
[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
