Description

Technical Field

[0001] This utility model relates to the field of safety helmet performance testing technology, and in particular to a safety helmet quality testing device. Background Technology

[0002] Safety helmets are an important piece of personal protective equipment, mainly used to protect the head from external impacts. They are commonly used on construction sites and in industrial settings, as well as for riding bicycles, motorcycles, and electric vehicles. They absorb the impact of falling objects, reduce vibrations to the head, and prevent collision injuries. They are widely used in various fields. To ensure the safety and reliability of safety helmets, quality testing is necessary.

[0003] When inspecting safety helmets, in addition to visually inspecting the integrity of the outer shell and inner liner, an impact test is also required. Existing technologies can only perform impact testing on one side of the safety helmet, making it inconvenient to test from different directions, resulting in an incomplete inspection. Therefore, this application provides a safety helmet quality inspection device to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a safety helmet quality testing device to solve the problem that the existing technology can only perform impact testing on one side of the safety helmet during the experiment, which is inconvenient to test in different directions and makes the testing incomplete.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A safety helmet quality inspection device includes an inspection platform. A placement seat for placing a safety helmet to be inspected is rotatably connected to the top center of the inspection platform. A fixing mechanism and an inspection mechanism are provided on the inspection platform. The inspection mechanism includes a fixing block fixedly connected to the top of the inspection platform. A second sliding groove is formed on the fixing block. A second sliding block is slidably connected to the side of the fixing block away from the placement seat. A first sliding groove is formed on the second sliding block. A first round rod is fitted onto the top of the second sliding block and slidably connected to the second sliding groove. One end of the first round rod passes through the second sliding groove, passes through the fixing block, and is fixedly connected to the second round rod. The second round rod and the placement seat are located on the same horizontal plane. An impact block is fixedly connected to the end of the second round rod away from the first round rod. A toothed block is fixedly connected to the side of the fixing block near the second round rod. A gear is fixedly connected to the outer wall of the first round rod, and the gear can mesh with the toothed block.

[0007] Preferably, the fixing mechanism includes a rotating rod located inside the testing platform. One end of the rotating rod is rotatably connected to the inner wall of the testing platform, and the other end of the rotating rod passes through the testing platform and is fixedly connected to a turntable. The outer surface of the rotating rod is provided with two threads inside the testing platform, and the threads rotate in opposite directions. A slider is helically connected to each thread of the rotating rod. A groove is provided above the threads on the top of the testing platform. The slider extends out of the groove and is slidably connected to the groove. A clamping block for holding the safety helmet to be tested on the placement seat is fixedly connected to the side of the slider that is close to each other.

[0008] Preferably, a placement platform is fixedly connected to the top of the testing platform, and a motor and a gearbox are installed on the top of the placement platform. The output end of the motor is aligned and connected with the input end of the gearbox. A connecting plate is fixedly connected to the output end of the gearbox, and a cylinder is fixedly connected to the side of the connecting plate away from the gearbox. The cylinder extends into the slide groove and is slidably connected to the slide groove.

[0009] Preferably, a sliding groove three is provided on one side of the testing platform, and a safety mechanism is provided on the testing platform. The safety mechanism includes a stop block, which extends through the testing platform into the interior of the testing platform and is slidably connected to the testing platform. A transmission plate is rotatably connected inside the testing platform. The top of one end of the transmission plate abuts against the stop block, and the end of the transmission plate away from the stop block extends outward through the sliding groove three.

[0010] Preferably, the stop block is fixedly connected to two limit plates on both sides of one end inside the detection table, and the limit plates are used to ensure the stability of the stop block's sliding.

[0011] Preferably, a slide groove four is provided on the side of the detection platform near the slide groove three, and a slider three is slidably connected inside the slide groove four. A limit rod is fixedly connected to the side of the slider three, and the limit rod is used to limit the position of the transmission plate.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] In the above solution, by setting up a fixing mechanism, when it is necessary to inspect the safety helmet, the safety helmet to be inspected is placed on the placement seat, and the turntable is rotated. When the turntable rotates, it will drive the threads to rotate, causing the two threads rotating in opposite directions to move the slider one closer to each other. When the slider one moves, the clamping block will gradually clamp the safety helmet placed on the placement seat. After the clamping block clamps and fixes the safety helmet, the turntable is no longer rotated. The advantage of doing this is that it can prevent the safety helmet from loosening during the inspection process, so that the inspection can be carried out stably.

[0014] By setting up a detection mechanism, after the safety helmet is clamped and fixed in place by the clamping block, the motor is started, and the connecting plate is rotated through the gearbox. When the connecting plate rotates, it causes the cylinder to slide inside the first slide groove. The second slider is driven to slide on the fixed block. When the fixed block slides, it causes the first round rod at the top of the fixed block to move downward together inside the second slide groove. When the first round rod moves downward, the gear will engage with the gear block to make the gear rotate, thereby driving the first round rod to rotate. When the first round rod rotates, it will drive the second round rod to rotate. During the process of the first round rod sliding downward inside the second slide groove, the second round rod drives the impact block to strike the safety helmet clamped and fixed in place on the placement seat. When one side of the safety helmet is struck by the impact block, the second round rod is reset, the placement seat is rotated so that the side of the safety helmet that was not struck faces the point to be struck, and the detection continues. The advantage of this is that it can perform impact detection on the safety helmet from different directions, avoiding the inability to specifically detect the overall impact resistance of the safety helmet by impact from a single direction, and ensuring the comprehensiveness and completeness of the safety helmet detection.

[0015] By setting up a safety mechanism, after inspecting the safety helmet, one end of the transmission plate can be pressed down on the outside of the inspection platform, causing it to move to the bottom of the slide groove three. The transmission plate will then rotate inside the inspection platform, pushing the stop block upwards. As the stop block moves upwards, it will contact the round rod two, causing the round rod two to rotate upwards to its reset position. When the limiting plate contacts the inner wall of the inspection platform, it will push the slider three, causing it to slide towards the transmission plate inside the slide groove four. This will move the limiting rod above the transmission plate, limiting its position. The advantage of this is that it prevents the round rod one from moving downwards due to malfunction when not in use or when adjusting the position of the placement seat, causing the impact block to strike the placement seat directly and injure the staff, thus ensuring safety.

Detailed Implementation

[0026] The following is a detailed description of a safety helmet quality testing device provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figures 1-5As shown, an embodiment of this utility model provides a safety helmet quality testing device, including a testing platform 1. A placement seat 2 for placing a safety helmet to be tested is rotatably connected to the top center of the testing platform 1. A fixing mechanism 3 and a testing mechanism 4 are provided on the testing platform 1. The testing mechanism 4 includes a fixing block 41 fixedly connected to the top of the testing platform 1. A second sliding groove 46 is provided on the fixing block 41. A second sliding block 42 is slidably connected to the side of the fixing block 41 away from the placement seat 2. A first sliding groove 43 is provided on the sliding block 42. The top of the second sliding block 42... The unit is fitted with a round rod 44, which is slidably connected to a groove 46. One end of the round rod 44 passes through the groove 46 and is fixedly connected to a fixing block 41 and a round rod 47. The round rod 47 and the placement seat 2 are on the same horizontal plane. An impact block 48 is fixedly connected to the end of the round rod 47 away from the round rod 44. A toothed block 49 is fixedly connected to the side of the fixing block 41 near the round rod 47. A gear 45 is fixedly connected to the outer wall of the round rod 44. The gear 45 can mesh with the toothed block 49. The fixing mechanism 3 includes a positioning mechanism. Inside the testing platform 1, there is a rotating rod 31. One end of the rotating rod 31 is rotatably connected to the inner wall of the testing platform 1, and the other end of the rotating rod 31 passes through the testing platform 1 and is fixedly connected to a turntable 33. The outer surface of the rotating rod 31 has two threads 32 inside the testing platform 1, and the threads 32 rotate in opposite directions. A slider 34 is helically connected to each thread 32 on the rotating rod 31. A groove 15 is opened above the thread 32 on the top of the testing platform 1. The slider 34 extends out of the groove 15 and is slidably connected to the groove 15. 34 are fixedly connected to each other on the side that are close to each other, and clamping blocks 35 are used to hold the safety helmet to be tested on the placement seat 2. The top of the testing table 1 is fixedly connected to the placement table 10. The top of the placement table 10 is equipped with a motor 11 and a gearbox 12. The output end of the motor 11 is aligned and connected with the input end of the gearbox 12. The output end of the gearbox 12 is fixedly connected to a connecting plate 13. The side of the connecting plate 13 away from the gearbox 12 is fixedly connected to a cylinder 14. The cylinder 14 extends into the slide groove 43 and is slidably connected to the slide groove 43.

[0028] By setting the fixing mechanism 3, when the safety helmet needs to be inspected, the safety helmet to be inspected is placed on the placement seat 2, and the turntable 33 is rotated. When the turntable 33 rotates, it will drive the thread 32 to rotate, so that the two threads 32 rotating in opposite directions will drive the slider 34 to move closer to each other. When the slider 34 moves, the clamping block 35 will gradually clamp the safety helmet placed on the placement seat 2. After the clamping block 35 clamps and fixes the safety helmet, the turntable 33 will no longer be rotated. The advantage of doing this is that it can prevent the safety helmet from loosening during the inspection process, so that the inspection can be carried out stably.

[0029] By setting up the detection mechanism 4, after the safety helmet is clamped and fixed by the clamping block 35, the motor 11 is started, which drives the connecting plate 13 to rotate through the gearbox 12. When the connecting plate 13 rotates, it drives the cylinder 14 to slide inside the first slide groove 43. The second slider 42 is driven to slide on the fixed block 41. When the fixed block 41 slides, it drives the first round rod 44 at the top of the fixed block 41 to move downward together inside the second slide groove 46. When the first round rod 44 moves downward, the gear 45 will engage with the gear block 49 to make the gear 45 rotate, thereby driving the first round rod 44 to rotate. When the first round rod 44 rotates, it drives the second round rod 47. As the round rod 44 slides downward inside the slide groove 46, the round rod 47 drives the impact block 48 to strike the safety helmet held and fixed on the placement seat 2 by the clamping block 35. After one side of the safety helmet is struck by the impact block 48, the round rod 47 is reset, the placement seat 2 is rotated so that the side of the safety helmet that has not been struck faces the area to be struck, and the test continues. The advantage of doing this is that it can perform impact testing on the safety helmet from different directions, avoiding the inability to specifically test the overall impact resistance of the safety helmet by impact from a single direction, and ensuring the comprehensiveness and completeness of the safety helmet test.

[0030] like Figure 1 , Figure 3 and Figure 6 As shown, a sliding groove 6 is provided on one side of the testing table 1. A safety mechanism 5 is provided on the testing table 1. The safety mechanism 5 includes a stop block 51, which extends through the testing table 1 and into its interior and is slidably connected to the testing table 1. A transmission plate 52 is rotatably connected inside the testing table 1. The top of one end of the transmission plate 52 abuts against the stop block 51. The end of the transmission plate 52 away from the stop block 51 extends outward through the sliding groove 6. Limiting plates 53 are fixedly connected to both sides of the end of the stop block 51 located inside the testing table 1. The limiting plates 53 are used to ensure the stability of the sliding of the stop block 51. A sliding groove 7 is provided on the side of the testing table 1 near the sliding groove 6. A slider 8 is slidably connected inside the sliding groove 7. A limiting rod 9 is fixedly connected to the side of the slider 8. The limiting rod 9 is used to limit the position of the transmission plate 52.

[0031] By setting up safety mechanism 5, after testing the safety helmet, one end of the transmission plate 52 can be pressed down on the outside of the testing platform 1, allowing one end of the transmission plate 52 to move to the bottom of the slide groove 6. The transmission plate 52 will rotate inside the testing platform 1, pushing the stop block 51 upward. When the stop block 51 moves upward, it will contact the round rod 47, causing the round rod 47 to rotate upward to its reset position. When the limiting plate 53 contacts the inner wall of the testing platform 1, it will push the slider 8, allowing the slider 8 to slide in the slide groove 7 towards the transmission plate 52, causing the limiting rod 9 to move above the transmission plate 52, thus limiting the transmission plate 52. The advantage of this is that it can prevent the round rod 44 from moving downward due to malfunction when not in use or when adjusting the position of the placement seat 2, causing the impact block 48 to strike the placement seat 2 directly and accidentally injure the staff, thus ensuring safety.

[0032] The technical solution provided by this utility model, by setting a fixing mechanism 3, when it is necessary to inspect the safety helmet, places the safety helmet to be inspected on the placement seat 2, and rotates the turntable 33. When the turntable 33 rotates, it will drive the thread 32 to rotate, so that the two threads 32 rotating in opposite directions will drive the slider 34 to move closer to each other. When the slider 34 moves, the clamping block 35 will gradually clamp the safety helmet placed on the placement seat 2. After the clamping block 35 clamps and fixes the safety helmet, the turntable 33 will no longer be rotated. The advantage of doing this is that it can prevent the safety helmet from loosening during the inspection process, so that the inspection can be carried out stably.

[0033] By setting up the detection mechanism 4, after the safety helmet is clamped and fixed by the clamping block 35, the motor 11 is started, which drives the connecting plate 13 to rotate through the gearbox 12. When the connecting plate 13 rotates, it drives the cylinder 14 to slide inside the first slide groove 43. The second slider 42 is driven to slide on the fixed block 41. When the fixed block 41 slides, it drives the first round rod 44 at the top of the fixed block 41 to move downward together inside the second slide groove 46. When the first round rod 44 moves downward, the gear 45 will engage with the gear block 49 to make the gear 45 rotate, thereby driving the first round rod 44 to rotate. When the first round rod 44 rotates, it drives the second round rod 47. As the round rod 44 slides downward inside the slide groove 46, the round rod 47 drives the impact block 48 to strike the safety helmet held and fixed on the placement seat 2 by the clamping block 35. After one side of the safety helmet is struck by the impact block 48, the round rod 47 is reset, the placement seat 2 is rotated so that the side of the safety helmet that has not been struck faces the area to be struck, and the test continues. The advantage of doing this is that it can perform impact testing on the safety helmet from different directions, avoiding the inability to specifically test the overall impact resistance of the safety helmet by impact from a single direction, and ensuring the comprehensiveness and completeness of the safety helmet test.

[0034] By setting up safety mechanism 5, after testing the safety helmet, one end of the transmission plate 52 can be pressed down on the outside of the testing platform 1, allowing one end of the transmission plate 52 to move to the bottom of the slide groove 6. The transmission plate 52 will rotate inside the testing platform 1, pushing the stop block 51 upward. When the stop block 51 moves upward, it will contact the round rod 47, causing the round rod 47 to rotate upward to its reset position. When the limiting plate 53 contacts the inner wall of the testing platform 1, it will push the slider 8, allowing the slider 8 to slide in the slide groove 7 towards the transmission plate 52, causing the limiting rod 9 to move above the transmission plate 52, thus limiting the transmission plate 52. The advantage of this is that it can prevent the round rod 44 from moving downward due to malfunction when not in use or when adjusting the position of the placement seat 2, causing the impact block 48 to strike the placement seat 2 directly and accidentally injure the staff, thus ensuring safety.
