Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] Such as figure 1 As shown, a safety helmet chin strap strength tester includes an electrical control box 1, a test platform 11, a column 2, a mounting frame 21, a lifting mechanism 3, a sensor module 4, a chin strap clamp 5, a fixed column 6, a head Die 7, conversion device 8, clamping seat 91 and clamping device 9. The electrical control box 1 is a box-shaped structure, its top is fixed to the test platform 11, and the upper surface of the test platform 11 is horizontal. The column 2 is a columnar structure with a rectangular cross section, which is arranged on the side of the test platform 11 away from the station of the testing personnel. The column 2 is vertically arranged, and the lower end of the column 2 is fixed to the upper surface of the test platform 11. The mounting frame 21 is a U-shaped block structure, which is arranged on the top of t...

The invention discloses a safety helmet chin strap strength tester. The safety helmet chin strap strength tester comprises an electrical control box, a test platform, an upright post, a mounting frame, a head mold and a lifting mechanism, wherein the lifting mechanism penetrates through the test platform and is fixed with a sensor module, and a chin strap fixture is fixed on the sensor module; a fixing column is arranged on the mounting frame, one end of the fixing column is fixed with the head mold, and the other end of the fixing column is rotatably connected to the mounting frame; a conversion device for driving the fixing column to rotate is arranged on the upright post; a clamping seat slidably installed with the upright post and a clamping device for driving the clamping seat to ascend and descend are further arranged on the upright post; a positioning groove matching an outer arc-shaped surface of a safety helmet is formed in an upper surface of the clamping seat, and a puncturehole penetrating through the clamping seat is formed in a bottom surface of the clamping seat; and an impact seat is fixed on the sensor module, and a puncture cone horizontally aligned with the positioning groove is fixed at the top of the impact seat. The safety helmet chin strap strength tester disclosed by the invention has the following effects: the safety helmet chin strap strength tester can test both the strength of the chin strap of the safety helmet and the puncture resistance of the safety helmet.
Description
technical field [0001] The invention relates to the field of engineering detection, in particular to a safety helmet chin strap strength tester. Background technique [0002] After the helmet manufacturer produces the finished helmet, it needs to conduct various tests on the parameters of the helmet, including the chin strap strength test and the puncture resistance test. Many instrument manufacturers in the market use two instruments to test these two There are few instruments that can detect two parameters at the same time, and there are generally complex operations and inconvenient disassembly and assembly. [0003] At present, the Chinese utility model patent with the notification number CN205679384U discloses a safety helmet chin strap strength lateral rigidity tester, which includes an electrical control box, a test platform is arranged on the electrical control box, and a column is fixed on the test platform. A beam is fixed, a headform support column is fixed on the...
