Technical Field

[0001] The utility model belongs to the technical field of electronic test fixtures, and more specifically, particularly relates to a wireless module vibration test fixture. Background Art

[0002] The vibration test of electronic products is to analyze the vibration mode of the test product under different vibration conditions, test the product's limit length and customize related characteristic specifications, screen defects, and ensure product quality.

[0003] In the vibration test of the wireless module, a clamp is required to clamp the substrate and the wireless module to simulate vibration on a vibration table. Currently, most clamps fix the substrate with bolts. The bolts are easy to loosen and fall off during the vibration process. Long-term vibration of the loose substrate can easily cause damage to the vibration table and the clamp.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a wireless module vibration test fixture is provided to achieve a more practical purpose. Utility Model Content

[0006] The purpose and effect of the protective bottle packaging box of the utility model are achieved by the following specific technical means:

[0007] A wireless module vibration test fixture comprises a clamping platform, a plurality of connecting seats are arranged at the bottom of the clamping platform, a plurality of connecting holes corresponding to the connecting seats and passing through the connecting seats are opened on the clamping platform, two sliding grooves are symmetrically arranged on the clamping platform, a clamping plate is slidably arranged in the sliding grooves, a base is arranged on both sides of the clamping platform, an adjusting rod for driving the clamping plate to move is rotatably connected between the two bases, a rotating prism is arranged in the middle of the adjusting rod, a locking plate is clamped between the rotating prism and the clamping platform, and the locking plate abuts against a plane on the rotating prism.

[0008] Furthermore, threads with opposite rotation directions are provided on both sides of the adjusting rod, and a moving part is provided at the bottom of the clamping plate. The moving part is sleeved at a corresponding position of the adjusting rod and is threadedly connected thereto.

[0009] Furthermore, a limiting rod is arranged in the slide groove, and the moving part is sleeved on the limiting rod.

[0010] Furthermore, a stop frame is provided at the bottom of the clamping platform, a movable groove is opened at the bottom of the clamping platform, the stop frame is slidably arranged in the movable groove, the stop frame is connected to the inner end wall of the movable groove through a spring, and the locking plate is surrounded by the stop frame.

[0011] Furthermore, an outer slope surface is arranged on the outer periphery of the stop frame, an inner slope surface parallel to the outer slope surface is opened on the inner wall of the stop frame, and outer slope surfaces matching the inner slope surface are arranged at both ends of the lock plate.

[0012] Furthermore, a wire groove is provided on the upper surface of the clamping platform.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By setting the locking plate, the adjusting rod is rotated to make the clamping plates close and clamp the substrate and the wireless module, and the locking plate can clamp one of the surfaces of the main rotating prism, so that the rotating prism cannot rotate. During the vibration process, the rotating prism is different from the bolt and cannot be affected by the rotational force, thus avoiding looseness between the two clamping plates, thereby basically driving the wireless module and the clamping platform to vibrate together, thereby extending the service life of the clamping platform and the clamping plate 6.

[0026] The utility model provides a wireless module vibration test fixture, including a clamping platform 1, a plurality of connection seats 3 are arranged at the bottom of the clamping platform 1, a plurality of connection holes 2 corresponding to the connection seats 3 and penetrating the connection seats 3 are opened on the clamping platform 1, the clamping platform 1 is installed on the vibration platform through the connection seats 3 and the connection holes 2, and the vibration of the vibration platform drives the clamping platform 1 to simulate vibration;

[0027] Two slide grooves 5 are symmetrically provided on the clamping platform 1, and a clamping plate 6 is slidably arranged in the slide grooves 5. Bases 4 are provided on both sides of the clamping platform 1, and an adjusting rod 8 for driving the clamping plate 6 to move is rotatably connected between the two bases 4. Figure 2 As shown, threads with opposite rotation directions are provided on both sides of the adjusting rod 8, and a moving part 61 is provided at the bottom of the clamping plate 6. The moving part 61 is sleeved on the corresponding position of the adjusting rod 8 and is threadedly connected with it. The two clamping plates 6 are driven to move away from and close to each other by rotating the adjusting rod 8. The wireless module is clamped between the two clamping plates 6 after being fixed on the base plate, and is vibrated and tested together with the clamping platform 1; and a wire groove 7 is provided on the upper surface of the clamping platform 1 to accommodate the wire harness led out of the wireless module.

[0028] A rotating prism 9 is provided in the middle of the adjusting rod 8, and a locking plate 11 is clamped between the rotating prism 9 and the clamping platform 1. The locking plate 11 abuts against a plane on the rotating prism 9 to limit the rotation angle of the rotating prism 9. In the embodiment, the rotating prism is a hexagonal prism. After the locking plate 11 is pulled out, the hexagonal prism can resume rotation again, and the position of the two clamping plates 6 can be controlled by the adjusting rod 8. Threads with opposite rotation directions are provided on both sides of the adjusting rod 8. A moving part 61 is provided at the bottom of the clamping plate 6. The moving part 61 is sleeved on the corresponding position of the adjusting rod 8 and is threadedly connected thereto. Rotating the adjusting rod 8 can drive the two clamping plates 6 to move relative to each other at the same time; and a limiting rod 62 is provided in the slide groove 5, and the moving part 61 is sleeved on the limiting rod 62, so that the movement of the clamping plate 6 is more stable.

[0029] Among them, a stop frame 10 is arranged at the bottom of the clamping platform 1, and a movable groove 12 is opened at the bottom of the clamping platform 1. The stop frame 10 is slidably arranged in the movable groove 12. The stop frame 10 is connected to the inner end wall of the movable groove 12 through a spring 13. The lock plate 11 is surrounded by the stop frame 10. The position of the lock plate 11 is limited by the stop block 10 to prevent the lock plate 11 from sliding from the side during the vibration of the clamping platform 1. When the lock plate 11 needs to be released, it only needs to push the stop frame 10 into the movable groove 12.

[0030] like Figure 4 As shown, an outer slope 14 is provided on the outer periphery of the stop frame 10, an inner slope 15 parallel to the outer slope 14 is provided on the inner wall of the stop frame 10, and outer slopes 16 matching the inner slope 15 are provided at both ends of the lock plate 11. During the vibration process, the lock plate 11 slides and applies a horizontal thrust to the stop frame 10, so that the stop frame 10 is subjected to a downward force component, thereby preventing the stop frame 10 from retracting into the movable groove 12 due to vibration collision.
