Description

Technical Field

[0001] This application relates to the field of safety helmet testing technology, and in particular to a structure for testing the stability of safety helmet wearing. Background Technology

[0002] Safety helmets are suitable for general workplaces and have basic protective performance, protecting against injuries caused by falling objects and other specific factors. To ensure the safety of safety helmets, they need to be tested. Safety helmet testing is usually to ensure that the safety helmet can protect the user's head under various conditions and prevent injury caused by accidental collisions or falls. In order to ensure that the safety helmet can be worn more stably and prevent it from falling off, a testing agency needs to test the wearing stability.

[0003] Currently, the common method for testing the wearing and stability of safety helmets is to pull them horizontally. This method is not convenient for switching between testing in both horizontal and vertical directions. As a result, different equipment is needed during the testing process, which is not only slow but also time-consuming, thus affecting testing efficiency. Therefore, this method needs to be improved. Utility Model Content

[0004] To facilitate switching between horizontal and vertical testing of safety helmets, this application provides a safety helmet wearing stability testing structure.

[0005] The helmet wearing stability test structure provided in this application adopts the following technical solution: The safety helmet wearing stability test structure includes a base, a positioning component on top of the base, a test component rotatably mounted inside the positioning component, a connecting component fixedly mounted at the connecting end of the test component, and an installation component on top of the base.

[0006] Optionally, the positioning component includes a bracket mounted on the upper surface of the base. The bracket has a first opening on both its front and back sides. An insert plate is slidably mounted on the inner wall of each first opening. A connecting plate is fixedly mounted on the side of each of the two insert plates that are far apart from each other. Two connecting blocks are fixedly mounted on the right side of the bracket. A second opening adapted to the insert plate is opened on the front of each connecting block.

[0007] By adopting the above technical solution, the first port and the second port can enable the insert plate to be inserted into the inside of the socket after the connecting frame rotates, thereby positioning the socket and preventing the connecting frame from shaking.

[0008] Optionally, the test assembly includes a rotating shaft rotatably mounted on the inner wall of a bracket via two bearings. A connecting frame is fixedly mounted on one side of the two rotating shafts that are close to each other. Both the front and back of the connecting frame have slots adapted to the insert plate. A U-shaped plate is fixedly mounted on the inner wall of the connecting frame. A rotating wheel is rotatably mounted on the inner wall of the U-shaped plate via a pin. A pull rope is provided inside the rotating wheel. A tension sensor is fixedly mounted at the bottom end of the pull rope. A spring is fixedly mounted at the bottom end of the tension sensor. A counterweight is fixedly mounted at the bottom end of the spring.

[0009] By adopting the above technical solution, the counterweight can apply tension to the spring and the tension sensor, enabling the tension sensor to pull the rope to move inside the wheel, allowing the rope to apply tension to the connecting components, and the spring can prevent excessive tension from causing damage to the safety helmet.

[0010] Optionally, the connecting assembly includes a tail hook installed at the left end of the pull rope, the right side of the tail hook having a threaded hole, and a threaded positioning rod being threadedly connected to the inner wall of the threaded hole.

[0011] Optionally, the mounting assembly includes a mounting bracket mounted on the upper surface of the base, a mounting column fixedly mounted on the upper surface of the mounting bracket, and a head mold fixedly mounted on the top of the mounting column.

[0012] Optionally, two first magnetic rings are fixedly installed on the front and back of the bracket, and the two first magnetic rings are attracted to the two connecting plates respectively. A second magnetic ring is fixedly installed on the side of the two connecting blocks that are far apart from each other, and a pull ring is fixedly installed on the side of the two connecting plates that are far apart from each other.

[0013] By adopting the above technical solution, the first magnetic ring and the second magnetic ring can attract the connection 203, preventing the plate from sliding during the test.

[0014] Optionally, two fixing seats are fixedly installed on the inner wall of the mounting bracket, and the bottom surface of each fixing seat is fixedly installed to the upper surface of the base.

[0015] Optionally, a control panel is fixedly installed on the front of the bracket, and a baffle is fixedly installed on one side of the two connecting blocks that are close to each other.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a tension sensor, tension spring, and counterweight, a tension force is applied to the tail hook, enabling the tail hook to apply tension to the safety helmet for testing the stability of the safety helmet. Through the cooperation of the first port, the second port, the connecting plate, and the insert plate, the insert plate can be inserted into the port according to the rotation of the connecting frame, so that the insert plate can position the connecting frame and thus keep the connecting frame stable. The position of the rotating wheel changes, and the direction of the tension force applied when pulling the safety helmet is changed by changing the position of the rotating wheel. This allows for switching between testing the safety helmet in both horizontal and vertical directions, thereby improving the efficiency of testing the stability of the safety helmet. 2. In use, first install the safety helmet on the head mold, pull the tail hook to fit the edge of the helmet, and rotate the threaded positioning rod to abut against the helmet through the threaded hole; push the counterweight upwards, then release it. Use the counterweight and spring to pull the tension sensor, causing the tension sensor to move the pull rope. The pull rope drives the rotating wheel to rotate, and the pull rope also moves the tail hook, causing the tail hook to pull the safety helmet to perform a horizontal test. After the horizontal test is completed, pull the pull ring and connecting plate to move the insert plate out of the insertion port and the second port, releasing the positioning of the connecting frame. Then rotate the connecting frame 90 degrees, and then insert the connecting plate and insert plate into the first port and insertion port again to reposition the connecting frame. The rotation of the connecting frame drives the rotating wheel to adjust its position, thus changing the direction of the tension applied by the tail hook and moving the tail hook upwards. Repeat the operation to complete the vertical test, thereby completing the horizontal and vertical stability test of the safety helmet. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a structure for testing the stability of a safety helmet. (Refer to...) Figure 1 The safety helmet wearing stability test structure includes a base 1, a positioning component 2 on top of the base 1, a test component 3 rotatably installed inside the positioning component 2, a connecting component 4 fixedly installed at the connecting end of the test component 3, and an installation component 5 on top of the base 1.

[0024] Reference Figure 2 The positioning component 2 includes a bracket 201 mounted on the upper surface of the base 1. The front and back of the bracket 201 are provided with first openings 202. An insert plate 208 is slidably mounted on the inner wall of each first opening 202. A connecting plate 203 is fixedly mounted on the side of the two insert plates 208 that are far apart from each other. Two connecting blocks 204 are fixedly mounted on the right side of the bracket 201. The front of each connecting block 204 is provided with a second opening 205 that is adapted to the insert plate 208. By providing the first opening 202 and the second opening 205, the insert plate 208 can be inserted into the inside of the insertion port 303 after the connecting frame 302 rotates, thereby positioning the insertion port 303 and preventing the connecting frame 302 from shaking.

[0025] Reference Figure 3The test assembly 3 includes a rotating shaft 301 rotatably mounted on the inner wall of a bracket 201 via two bearings. A connecting frame 302 is fixedly mounted on one side of the two rotating shafts 301 that are close to each other. Both the front and back of the connecting frame 302 have insertion slots 303 adapted to the insertion plate 208. A U-shaped plate 304 is fixedly mounted on the inner wall of the connecting frame 302. A rotating wheel 305 is rotatably mounted on the inner wall of the U-shaped plate 304 via a pin. A pull rope 306 is provided inside the rotating wheel 305. The bottom of the pull rope 306... A tension sensor 307 is fixedly installed at one end, and a spring 308 is fixedly installed at the bottom end of the tension sensor 307. A counterweight 309 is fixedly installed at the bottom end of the spring 308. By providing the counterweight 309, a tension force can be applied to the spring 308 and the tension sensor 307, so that the tension sensor 307 can pull the pull rope 306 to move inside the rotating wheel 305, so that the pull rope 306 can apply a tension force to the connecting component 4. The spring 308 can prevent the applied tension from being too large, and prevent the safety helmet from being damaged due to excessive tension.

[0026] Reference Figure 4 The connecting component 4 includes a tail hook 401 installed at the left end of the pull rope 306. A threaded hole 402 is provided on the right side of the tail hook 401. A threaded positioning rod 403 is threadedly connected to the inner wall of the threaded hole 402. Through the cooperation of the threaded positioning rod 403 and the threaded hole 402, the tail hook 401 can be positioned on the safety helmet to prevent the tail hook 401 from falling off and to transmit the pulling force to the safety helmet.

[0027] Reference Figure 1 The installation component 5 includes a mounting bracket 501 mounted on the upper surface of the base 1. A mounting post 502 is fixedly mounted on the upper surface of the mounting bracket 501. A head mold 503 is fixedly mounted on the top of the mounting post 502. The safety helmet can be installed on the head mold 503 by providing the head mold 503.

[0028] Reference Figure 2 Two first magnetic rings 206 are fixedly installed on the front and back of the bracket 201. The two first magnetic rings 206 are attracted to the two connecting plates 203 respectively. A second magnetic ring 207 is fixedly installed on the side of the two connecting blocks 204 that are far apart from each other. A pull ring 209 is fixedly installed on the side of the two connecting plates 203 that are far apart from each other. The connecting plates 203 can be attracted by the first magnetic rings 206 and the second magnetic rings 207 to prevent the insert plate 208 from sliding during the test.

[0029] Reference Figure 1 The inner wall of the mounting bracket 501 is fixedly installed with two fixing seats 504. The bottom surface of each fixing seat 504 is fixedly installed with the upper surface of the base 1. The mounting bracket 501 can be reinforced by the fixing seats 504, the stability of the fixing seats 504 can be improved, and the fixing seats 504 can be prevented from becoming loose.

[0030] Reference Figure 1 and Figure 2 The control panel 6 is fixedly installed on the front of the bracket 201. The two connecting blocks 204 are fixedly installed on the same side that are close to each other. The baffle 210 can limit the connecting bracket 302 so that the connecting bracket 302 can be kept in a horizontal state and it is convenient to align the socket 303 and the second port 205.

[0031] The implementation principle of the helmet wearing stability test structure in this application embodiment is as follows: First, the helmet is installed on the head mold 503. Then, the tail hook 401 is pulled to fit around the edge of the helmet. Next, the threaded positioning rod 403 is rotated so that it contacts the helmet through the threaded hole 402, connecting with the helmet. Then, the counterweight 309 is pushed upwards and released. The weight of the counterweight 309 and the spring 308 pulls the tension sensor 307, causing the tension sensor 307 to move the pull rope 306. The pull rope 306 then drives the rotating wheel 305 to rotate, and the pull rope 306 pulls the tail hook 401, causing the tail hook 401 to pull the helmet and perform a level test.

[0032] After the horizontal test is completed, by pulling the pull ring 209 and the connecting plate 203, the connecting plate 203 pulls the insert plate 208 to move, causing the insert plate 208 to move out of the insertion port 303 and the second through port 205, thus releasing the positioning of the connecting frame 302. Then, the connecting frame 302 is rotated 90 degrees. The connecting plate 203 and the insert plate 208 are then inserted into the first through port 202 and the insertion port 303, and the connecting frame 302 is positioned again. The rotation of the connecting frame 302 drives the rotating wheel 305 to adjust its position. Therefore, the pull rope 306 can change the direction of the pulling force applied by the tail hook 401, causing the pull rope 306 to drive the tail hook 401 to move upward. The operation is repeated to complete the vertical test, thus completing the horizontal and vertical stability test of the safety helmet.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
