[0039] Working principle: The whole finished bracket is used for supporting and installing the helmet, and the helmet destruction test is carried out. The side seat 2 provides a mounting hole position through the mounting hole 4, and the whole bracket can be installed on the external mounting surface through screws or bolts; and the hammer head of the destruction device is located above the middle of the whole bracket;
[0040] When performing a destructive test, the helmet is worn on the head mold 9, and the slider 19 is located in the middle of the cross slot 3, and the support rod 7 is in a vertical state, so that the top of the helmet faces the hammer head, and the hammer head can hit the top of the helmet, and a destructive test of the top of the helmet is performed;
[0041] Before conducting a destructive test at the front, back, left or right side of the helmet, an adjustment is performed so that the front, back, left or right side of the helmet is located below the hammer head; the specific adjustment operation is as follows: first, the positioning of the positioning and clamping mechanism is released, and the second bevel gear 30 is rotated by rotating the first driving rod 10. The rotating shaft 27, the first screw rod 12 and the second screw rod 26 are rotated together through the meshing transmission between the second bevel gear 30 and the first bevel gear 28. When the first screw rod 12 rotates, the movable plate 14 is driven to move toward the bottom through the screwing of the first screw rod 12 and the thread groove, and the guidance of the guide rod 17 and the guide hole 18. The spring 15 is moved downward to reduce the compression of the spring 15 until the spring 15 returns to the uncompressed state, that is, the movable plate 14 contacts the stopper 13, and the pressure plate 16 does not press the bottom of the carrier plate 1, thereby releasing the clamping positioning of the slider 19, and the slider 19 can slide in the cross groove 3; when the second screw rod 26 rotates, the second screw rod 26 and the screw hole 24 are screwed together, and the square rod 23 can be driven to move downward in conjunction with the vertical guide of the square rod 23 and the square hole, and the square rod 23 leaves the positioning hole 22, canceling the positioning of the round cover 21; the round cover 21 can be rotated forward, backward, left, or right on the ball head seat 25, so that The support rod 7 and the structure on the support rod 7 are tilted forward, backward, left or right. Correspondingly, the support rod 7 can enter the four tilted grooves 6 on the movable block 5 and complete the tilt adjustment by contacting the groove wall of the tilted groove 6. After the above adjustment, the positioning holes 22 on the front, back, left or right sides of the inner wall of the round cover 21 can be aligned with the ends of the square rods 23. At the same time, after adjustment, the front, back, left or right sides of the safety helmet can be faced upward. After the tilt adjustment, the safety helmet can be moved horizontally or vertically by pulling the slider 19 to slide in the cross groove 3 until the safety helmet is located below the hammer head. Then, by rotating the first driving rod 1 0, drive the movable plate 14 and the square rod 23 upward, the square rod 23 is pressed and inserted into the positioning hole 22, and the round cover 21 is positioned, so that the round cover 21 cannot rotate on the ball head seat 25, and the movable plate 14 is upward, and the spring 15 is compressed, so that the pressure plate 16 is pressed to the bottom surface of the carrier plate 1, wherein the number of springs 15 is set to be several, and by compressing multiple springs 15 at the same time, the elastic force of multiple springs 15 is superimposed, providing a larger clamping force for the carrier plate 1, ensuring the clamping and positioning effect, so that the slider 19 cannot slide; after the above positioning, the destructive test of the front, rear, left, or right side of the safety helmet can be carried out;
[0042] During the destructive experiment, the head mold 9 is damaged and needs to be replaced. The first driving rod 10 is rotated to rotate the threaded shaft 33, and the threaded shaft 33 and the nut 34 are threaded. With the guidance of the slider 19 in the groove 32, the slider 19 can be driven to slide in the groove 32. Since the two external threads on the threaded shaft 33 have opposite rotation directions and the two nuts 34 are adapted to the two external threads, the two clamping blocks 36 can be driven to move closer to or away from each other. By driving the two clamping blocks 36 closer to each other, the clamping and clamping of the wall of the clamping groove 31 can be canceled. The head mold 9 can be manually lifted and removed, and then the clamping groove 31 at the bottom of the new head mold 9 can be installed on the clamping block 36. By driving the two clamping blocks 36 away from each other, the wall of the clamping groove 31 is clamped to achieve installation and positioning.
