Technical Field

[0001] The utility model relates to the technical field of aviation accessory detection equipment, in particular to an aviation seat belt sliding belt detection device. Background Technique

[0002] An aviation seat belt is a safety device used to restrain passengers during a collision, prevent secondary collisions between passengers and seats or aircraft during a collision, or prevent passengers from being thrown out of the seat and suffering casualties during a collision.

[0003] As an important equipment to ensure the life safety of passengers and crew, the stability and reliability of the performance of aviation seat belts are crucial. Therefore, various tests need to be carried out when aviation seat belts are produced. Among them, the sliding belt test is a key link to evaluate whether the seat belt can effectively fix the passenger's body and prevent slipping under specific conditions. Through the sliding belt test, it can be ensured that the seat belt can play its due role at a critical moment and protect passengers from harm.

[0004] At present, aviation seat belts are all detected by a sliding belt detection device. On the sliding belt detection device, when the existing sliding belt detection device tests an aviation seat belt, it will pull the aviation seat belt. When the aviation seat belt is pulled, it will twist. The twisting of the aviation belt during the detection will affect the test results. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that when the sliding belt detection device mentioned in the above background technique tests an aviation seat belt, it will pull the aviation seat belt.

[0031] Embodiment:

[0032] Please refer to Figures 1 - 6 , an aircraft seat belt slippage detection device, which includes a base 1, a fixing frame 2, a force receiving mechanism 5, and an anti-twist member 6. The fixing frame 2 is arranged on the base 1. A cylinder 3 is arranged above the fixing frame 2. A tensile mechanism 4 for pulling the aircraft seat belt is arranged on the output shaft of the cylinder 3. The force receiving mechanism 5 is arranged below the fixing frame 2 and is used for detecting the force when the aircraft seat belt is pulled. The anti-twist member 6 is arranged on the fixing frame 2 and is used to prevent the aircraft seat belt from twisting. The anti-twist member 6 includes an anti-twist rod one 61 and an anti-twist rod two 62. The anti-twist rod one 61 and the anti-twist rod two 62 are symmetrically arranged inside the fixing frame 2. The aircraft seat belt can be limited by the anti-twist rod one 61 and the anti-twist rod two 62 so that no twisting phenomenon occurs when it is pulled for slippage testing.

[0033] Further, the anti-twist bar 61 includes a connecting rod 612. One end of the connecting rod 612 is connected with a first connecting block 611, and the other end of the connecting rod 612 far from the first connecting block 611 is connected with a second connecting block 613. An articulated groove 6122 is provided at the end of the connecting rod 612 connected to the first connecting block 611. An articulated end 6111 is provided on the first connecting block 611. The articulated end 6111 is located in the articulated groove 6122, and the first connecting block 611 and the connecting rod 612 are rotationally connected through a positioning pin. A connecting end 6121 is provided at the end of the connecting rod 612 far from the first connecting block 611. A connecting piece for quickly connecting the connecting end 6121 is provided on the second connecting block 613. The connecting end 6121 can be separated from the second connecting block 613 through the connecting piece, so that the connecting rod 612 can rotate downward, facilitating the user to place the aviation safety belt between the anti-twist bar 61 and the anti-twist bar 62.

[0034] Furthermore, the connecting piece includes a positioning plate 6133. A connecting groove 6131 is formed on the second connecting block 613. The positioning plates 6133 are symmetrically arranged in the connecting groove 6131. The connecting end 6121 can be squeezed and clamped by the two positioning plates 6133, so as to quickly position and clamp the connecting end 6121. Grooves 6132 are symmetrically provided in the connecting groove 6131. One end of the positioning plate 6133 is fixedly connected to the second connecting block 613, and the other end is located in the groove 6132. One end of the positioning plate 6133 is located in the groove 6132, so that the deformation of the positioning plate 6133 will not be affected when it deforms. The positioning plate 6133 is an elastic plate body that can deform during use. When the deformable positioning plate 6133 is squeezed by the connecting end 6121, it will deform inward, facilitating the user to quickly connect and separate the connecting rod 612 from the second connecting block 613.

[0035] It should be noted that the tension mechanism 4 includes a first fixing plate 41 and a hanging belt 43. The first fixing plate 41 is fixedly connected to the output shaft of the air cylinder 3. Hanging holes are symmetrically formed at both ends of the first fixing plate 41. Hooks 42 are connected to both ends of the hanging belt 43. The two hooks 42 are respectively hung in the two hanging holes on the first fixing plate 41. One end of the aviation safety belt can be hung on the hanging belt 43. The air cylinder 3 can pull the tension mechanism 4 upward, and then can pull the aviation safety belt so that the aviation safety belt has a pulling force on the force-bearing mechanism 5.

[0036] It should be added that the force-bearing mechanism 5 includes a force-bearing rod 51. A second fixing plate 52 is fixed on the force-bearing rod 51. A fixing rod 53 is fixed on the second fixing plate 52. A connecting hook 54 is provided on the fixing rod 53. The other end of the aviation safety belt can be hung on the connecting hook 54. When the aviation safety belt is detected and pulled, it will have an upward pulling force on the force-bearing rod 51. A pressure sensor is provided inside the force-bearing rod 51 to detect the pulling force of the aviation safety belt, so as to detect the slipping situation of the aviation safety belt.

[0037] When this utility model is in use, first rotate the connecting rod 612 downward. The connecting end 6121 on the connecting rod 612 presses the positioning plate 6133 inward, causing the positioning plate 6133 to deform inward, so that the connecting end 6121 can be rotated out of the connecting groove 6131. Then, hang the two ends of the aviation safety belt on the connecting hook 54 and the hanging belt 43 respectively. Move the belt body of the aviation safety belt close to the anti-twist rod two 62. Then rotate the connecting rod 612 upward. When the connecting end 6121 on the connecting rod 612 is rotated into the connecting groove 6131, when the connecting end 6121 contacts the positioning plate 6133 again, it can exert an inward pressing force on the positioning plate 6133, causing the positioning plate 6133 to deform inward, so that the connecting end 6121 can be rotated through the positioning plate 6133 into the connecting groove 6131. After the connecting end 6121 passes through the positioning plate 6133, the positioning plate 6133 resets to position the connecting end 6121, thus quickly fixing the connecting end 6121 in the connecting groove 6131. The belt body of the aviation safety belt is located between the anti-twist rod one 61 and the anti-twist rod two 62, so that when the aviation safety belt is pulled for slip belt detection, the situation of torsion can be avoided, thus ensuring the accuracy of the aviation safety belt detection.

[0038] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the drawings are only examples and do not limit the present utility model. The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been shown and described in the embodiments. Without departing from the above principles, any deformation or modification of the embodiments of the present utility model is possible.
