as shown in fig. 1, 2 and 3, the utility model discloses a helmet drop hammer test positioning device, which comprises a base 1, wherein one end of the base 1 is rotatably connected with a mounting plate 2 through a pin shaft 3, two sides of the end part of the mounting plate 2 far away from one end of the pin shaft 3 are respectively rotatably connected with a first connecting rod 4, two sides of the base 1 at the corresponding end are respectively rotatably connected with a second connecting rod 5, and the second connecting rods 5 are rotatably connected with the corresponding first connecting rods 4; the helmet mounting structure is characterized in that a first support 6 and a second support 8 are respectively arranged on two sides of the mounting plate 2, a first inserting rod 7 is arranged at the upper end of the first support 6, a second inserting rod 9 is arranged at the upper end of the second support 8, the first inserting rod 7 and the second inserting rod 9 are respectively inserted into holes in two sides of a helmet to be tested, a supporting mechanism is arranged between the base 1 on one side of the first connecting rod 4 and the second connecting rod 5 and the mounting plate 2, and the supporting mechanism is used for adjusting and limiting the angle between the base 1 and the mounting plate 2.

Wherein, the first inserted bar 7 on the first support 6, the second inserted bar 9 on the second support 8 are located the both sides of helmet respectively, peg graft in the through-hole that the helmet corresponds, realize the fixed to the helmet, and fixed stable firm. According to actual test needs, adjust supporting mechanism to change the angle between mounting panel 2 and the base 1, thereby change the position that the helmet faces upward, cooperation weight testing arrangement can realize the test to the different angles in different positions of helmet, promotes test performance and efficiency of software testing.

The structure of the supporting mechanism is as follows: including support column 11, support column 11 comprises supporting part 14 and sliding part 13, supporting part 14 is used for contacting with the lower surface of mounting panel 2, sliding part 13 be used for with 1 sliding connection of base, upwards extend on the base 1 that is close to head rod 4 and 5 one ends of second connecting rod have locating plate 12, be provided with the screw on locating plate 12, be provided with lead screw 10 in the screw, rotate between the one end of lead screw 10 and the sliding part 13 of support column 11 and be connected, lead screw 10 rotates the drive support column 11 reciprocating motion on base 1.

The rotation of the screw rod 10 can drive the supporting column 11 to move on the base 1, so that the supporting position of the supporting column 11 for the mounting plate 2 is changed, the angle between the mounting plate 2 and the base 1 is adjusted, wherein the axial direction of the supporting part 14 of the supporting column 11 is perpendicular to the mounting plate 2, so that the supporting capacity is strong, the helmet can still be kept stable under the action of a heavy hammer, the testing performance is improved, and the adjusting process is simple and convenient.
