[0023] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0024] This embodiment is a fixture for producing safety helmets.

[0025] AsFigures 1-4 As shown in the figure, it includes a safety helmet fixture 2. The lower outer surface of the safety helmet fixture 2 is connected with a height adjustment bracket 1. The safety helmet fixture 2 includes a head mold 4, an internal thread hole 5, an annular air passage groove 6, an air valve 7 and an annular rubber ring 8. The height adjustment bracket 1 includes a base 9, a lower fixed rod 10, an upper adjustment rod 11, a first screw 12, a fixing ring 13, a second screw 14 and a storage hole 15. The internal thread hole 5 is opened in the middle of the lower outer surface of the head mold 4. The head mold 4 is threadedly connected with the outer wall of the first screw 12 through the internal thread hole 5.

[0026] The annular air passage groove 6 is opened on the outer wall of the lower end of the head mold 4. The annular rubber ring 8 is fixedly installed in the annular air passage groove 6. The air valve 7 is fixedly installed on one side of the lower outer surface of the head mold 4, and the upper end of the air valve 7 extends into the annular air passage groove 6.
