Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a tension detection mechanism for an aircraft seat safety belt. Background Art

[0002] Seat belts are safety parts used on equipment. They are used to ensure safety when riding in aircraft or other aircraft, or when working at high altitudes or performing skills. The main raw materials are polyester, polypropylene, and nylon. Seat belts do not only refer to webbings. In addition to webbings, seat belts are assembled from other parts.

[0003] Existing tension detection mechanisms for aircraft seat belts, for example, a tension detection device for aircraft anti-fall seat belt production disclosed in Chinese patent application CN215812013U, states that: a thread is fixed to the outer surface of one end of the limit rod away from the rotating block, a limit bolt is sleeved on the outer surface of the limit rod, the limit bolt is threadedly connected to the limit rod through a thread, and the diameter of the lower surface of the limit bolt is greater than the width and length of the third groove, so that the limit block can be easily fixed to the fixed block, thereby facilitating the fixing of the seat belt.

[0004] The above-mentioned tension detection mechanism of the aircraft seat belt is unable to tighten and fix the seat belts of different lengths when in use. In the above-mentioned seat belt tension test, since the staff is required to fix both sides of the seat belt, it is inevitable that the seat belt will be loose after the fixation is completed. When the seat belt is loose, the seat belt can only be pulled longer to complete the overall test, resulting in the extension of the seat belt test process, thereby reducing the test efficiency and affecting the accuracy of the test results. When the test results are affected, the user will mistakenly believe that the performance of the seat belt meets the standard, but it cannot provide sufficient protection in actual use.

[0027] The detection and tensioning mechanism 200 includes a support frame 201, a fixed cylinder 202, a torsion spring baffle 203, a corrugated slot 204 and a rotating wheel 205. The support frame 201 is fixedly connected to the upper surface of the base plate 100, one side of the fixed cylinder 202 is fixedly connected to the support frame 201, the torsion spring baffle 203 is torsionally connected to the fixed cylinder 202, the corrugated slot 204 is arranged on the torsion spring baffle 203, the rotating wheel 205 is rotatably connected to the fixed cylinder 202, and the corrugated slot 204 is installed in the rotating wheel 205. By rotating the rotating wheel 205 clockwise, the corrugated slot 204 on the inner wall is driven to slide along the top of the raised torsion spring baffle 203 and can rotate smoothly. When rotating counterclockwise, the corrugated slot 204 will be clamped with the raised torsion spring baffle 203, so that the rotating wheel 205 cannot rotate.

[0028] A fixed plate 206 is fixedly connected to one side of the rotating wheel 205, and a handle 207 is rotatably connected to the top of the fixed plate 206. The rotating wheel 205 is driven to rotate by the handle 207 and the fixed plate 206. The handle 207 can be rotated to enable the operator to exert better force during operation.

[0029] During use, by rotating the rotating wheel 205 clockwise, the corrugated groove 204 on the inner wall is driven to slide along the top of the tilted torsion spring baffle 203, and can rotate smoothly. When rotating counterclockwise, the corrugated groove 204 will be engaged with the tilted torsion spring baffle 203, so that the rotating wheel 205 cannot rotate. Pressing the tilted torsion spring baffle 203 can rotate counterclockwise, which can tighten the loose seat belts and keep seat belt buckets of different lengths in a taut state at all times, which is convenient for tension testing.

This tension detection mechanism for an aircraft seat belt includes a torsion spring clip 208 installed on a rotating wheel 205, and a seat belt 209 is fixedly connected to the torsion spring clip 208. By pressing the tail of the torsion spring clip 208, the seat belt 209 is placed into the front end of the torsion spring clip 208 for clamping and fixing.

A fixed block 213 is slidably connected inside the fixed position 212. The fixed block 213 slides and is inserted into the fixed position 212 on the latch 210 to fix the latch 210, thereby preventing the latch 210 from falling off due to excessive pressure during the tensile test.

By pushing the sliding block 214 to the left, the fixed block 213 is driven to a fixed position 212 on a latch 210. At this time, the latch 210 can be pulled out. When the sliding block 214 is released, the return spring 215 is set to automatically restore it.

[0035] During use, the end of the safety belt 209 is fixed to the support seat 211 by the pin, and the fixing block 213 is inserted into the fixed position 212 on the pin 210 by sliding, so as to fix the pin 210 to prevent excessive pressure in the tensile test from causing the pin 210 to fall off. By pushing the sliding block 214 to the left, the fixing block 213 is driven to the fixed position 212 on the pin 210. At this time, the pin 210 can be pulled out. When the sliding block 214 is released, the reset spring 215 is set to automatically restore it, so as to facilitate the continuous use of the equipment.
