Description

Technical Field

[0001] The utility model relates to the technical field of safety helmet detection, in particular to a multi-environment simulation safety helmet detection device. Background Art

[0002] A hard hat is a piece of protective equipment used to protect the head from falling objects or other potentially dangerous injuries. It is widely used in high-risk work environments such as construction, mining, and factories. It consists of an outer shell, a cushioning layer, and a wearing device. The outer shell is usually made of a sturdy material such as high-density polyethylene or fiberglass, which has good impact and puncture resistance. The cushioning layer is used to absorb and disperse external forces, reducing direct damage to the head caused by impact. The wearing device can adjust the distance between the head and the helmet shell, further improving comfort and protective effects. Hard hats not only meet the testing requirements of national or international standards, but also effectively reduce injuries to the head caused by accidents in the workplace. They are important equipment for protecting worker safety.

[0003] To ensure that hard hats meet national or international production and safety standards, random sampling safety quality inspections are required after production. Currently, existing hard hat testing devices, due to a lack of multi-environmental simulation testing conditions, primarily conduct basic pressure impact tests on hard hats. This makes it difficult to meet the testing requirements for more complex conditions, such as simulating high-temperature environments. Consequently, there may be certain limitations in comprehensively evaluating their performance in different extreme environments. This limitation may affect in-depth verification of the reliability and protective performance of hard hats in these environments.

[0004] Based on this, we propose a multi-environment simulation helmet detection device to solve the above-mentioned problems. Utility Model Content

[0028] The slide groove 23 and the guide plate 19 are in sliding cooperation, and the electric heating tube 24 and the arc-shaped groove 20 are in embedded cooperation. Through the structural design of the sliding cooperation between the slide groove 23 and the guide plate 19, the two sides of the horizontally movable metal frame 4 can be guided and limited. A guide groove 25 is provided through the top of the adjustment base 1 and the bottom of the heat insulation box 3. A second slider groove 26 is provided inside the adjustment base 1. The four corners of the bottom of the adjustment base 1 are connected to moving wheels 27. Adjustment plates 28 are installed at both ends of the adjustment base 1.

The second support rod 31, the first support rod 18 and the guide groove 25 are slidingly matched. Through the structural design of the sliding match between the first support rod 18, the second support rod 31 and the guide groove 25, when the adjustment screw 29 installed between the two sets of adjustment plates 28 is rotated in the positive or negative direction, the adjustment base 1 can horizontally displace the metal frame 4 connected to the top.

[0029] Working principle: This solution is through the safety detection component 2 installed on the top of the adjustment base 1, wherein the safety detection component 2 is mainly composed of a heat insulation box 3 and a metal frame 4. The metal frame 4 is connected to the first support rod 18 installed at the bottom and the second support rod 31 installed on the top of the adjustment base 30. Since the second support rod 31 has the same structure as the first support rod 18, the metal frame 4 with the safety helmet body 5, the impact cylinder 8 and the pressure impact component 9 installed inside can be fixed on the top of the adjustment base 1. When the adjustment screw 29 installed between the two sets of adjustment plates 28 is rotated in the positive or negative direction, the first support rod 18, the second support rod 31 and the guide groove are connected. 25 are designed to slide together, and the adjustment base 1 can horizontally displace the metal frame 4 connected to the top. When the metal frame 4 is horizontally displaced and adjusted to the outside of the heat insulation box 3, the safety detection component 2 can perform a pressure shock test on the helmet body 5 to be tested under normal temperature conditions through the use of the impact cylinder 8 and the pressure shock component 9. When the metal frame 4 is horizontally displaced and adjusted to the inside of the heat insulation box 3, the sealing door on one side of the heat insulation box 3 is closed, and the electric heating tube 24 installed inside the heat insulation box 3 is energized. At this time, the safety detection component 2 can perform a pressure shock test on the helmet body 5 to be tested under high temperature conditions.

[0030] This solution uses two sets of snap-fit ​​grooves 12 opened at the bottom of the connecting plate body 10 and two sets of snap-fit ​​plates 15 installed on the top of the impact plate 11. Since the snap-fit ​​grooves 12 and the snap-fit ​​plates 15 are plug-fitted to each other, the impact plate 11 used for the pressure impact of the safety helmet body 5 can be limited to the output ends of the two sets of impact cylinders 8. Combined with the structural design of the snap-fit ​​between the positioning slots 17 and the elastic block 14, the impact plate 11 limited between the output ends of the two sets of impact cylinders 8 can also be snap-fitted and fixed, which can effectively improve the stability of the connection between the impact plate 11 and the impact cylinder 8. From the above, it can be seen that the safety detection component 2 designed in this solution can disassemble, connect, repair and replace the impact plate 11 according to the test usage, and can replace and assemble the impact plate 11 with different pressure impact test effects such as collision and puncture.
