Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a safety belt integral slip-off reliability tester. Background Art

[0002] Seat belts are safety parts used on equipment. They are used to ensure safety when riding in aircraft or performing at high altitudes. The main raw materials are polyester, polypropylene, and nylon. Seat belts do not only refer to webbings. In addition to webbings, seat belts are also assembled with other parts. A seat belt overall slip reliability tester is a reliable tester for the anti-slip condition of seat belts at high altitudes.

[0003] According to the authorized patent: "CN210108701U", the utility model discloses a seat belt integral slip tester, which relates to the technical field of seat belt testing equipment, including a support base, the upper surface of the support base is fixedly connected with a support sleeve, the interior of the support sleeve is plugged with a support column, one side of the upper surface of the support base is fixedly connected with a flap limit frame, and both sides of the bottom wall of the flap limit frame are fixedly connected with a reset spring. The seat belt integral slip tester, through the arrangement of the flap, reset spring, pull rod and flap limit frame, after the tester places the simulated person on the flap and pulls the pull rod, the flap will drop after losing the support of the pull rod. During the drop, the reset spring can speed up the drop speed of the flap according to inertia, avoid friction between the flap and the simulated person, slow down the drop speed of the simulated person, and thus affect the accuracy of the test data. In actual use, although the above patent has the function of testing the safety belt, there are many different heights in high-altitude operations, and it lacks drop tests at different heights, which makes its practicality relatively insufficient. At the same time, it uses a spring to limit the flap to prevent it from shaking, which will affect the falling trajectory when danger occurs in actual high-altitude operations, so that the above patent has an impact on the overall test data, making the test data insufficiently accurate.

DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] Example: Figure 1 As shown, a safety belt overall slip reliability tester is provided, by providing a bracket 1, so that the bracket 1 can be used to provide other components thereon, or indirectly provided to connect other components, so as to form this novel tester, and at the same time, the bracket 1 can be used to support the components thereon, and by installing a bottom plate 2 at the bottom of the bracket 1, the bottom plate 2 can be used to protect the electric cylinder 8 penetrating and provided at the top thereof, and by providing an adjustment column 3 between the brackets 1, and connecting the adjustment column 3 to the upper and lower inner walls of the bracket 1, so that the connector 4 sleeved on the adjustment column 3 can be moved up and down inside the bracket 1. It can move vertically without detachment, so that the seat belt can be tested for slippage for a long time. By evenly penetrating the side of the adjusting column 3 with limit holes 10 and setting a limit rod 11 on the side of the connector 4, when the connector 4 needs to be fixed, the limit rod 11 is passed through the connector 4 and the limit hole 10, and the limit nut 12 is used to lock the two sides of the limit rod 11 to prevent the limit rod 11 from falling off during use. The output end of the electric cylinder 8 is connected to the push rod 9, so that the push rod 9 can be driven by the electric cylinder 8 to rise and fall vertically, thereby supporting the seat plate 7.

[0041] like Figure 2 As shown, by installing the rotating shaft 5 through both sides of the connector 4, and connecting the connecting plate 6 on the front side of the rotating shaft 5, and welding the seat plate 7 on the front side of the connecting plate 6, the seat plate 7 can be controlled by the rotating shaft 5, so that the seat plate 7 can be rotated by the rotating shaft 5, so that when the push rod 9 supporting the bottom of the seat plate 7 falls, the seat plate can be rotated downward by the rotating shaft 5, so that the safety belt set for the dummy placed above the seat plate 7 can be subjected to a slip test.

[0042] like Figure 3As shown, when it is necessary to conduct multiple seat belt drop tests at different heights, it is necessary to collect dummies multiple times and place them on the seat board 7, so that a take-up reel 13 can be set on the top of the bracket 1, and the seat belt rope is wound around the take-up reel 13. By setting a motor 14 on the left side of the take-up reel 13, and the motor 14 is connected to the take-up reel 13 by a rotating rod, the motor 14 can drive the take-up reel 13 to rotate, so that after each test is completed, the motor 14 can cooperate with the electric cylinder 8 to operate. When the motor 14 drives the take-up reel 13 to reel in and lift the dummy, the staff will coordinate the seat board 7 to return to the center, and start the electric cylinder 8, and press the push rod 9 against the bottom of the seat board 7. At this time, the dummy after the reeling is completed is placed on the seat board 7, so that the next seat belt drop test can be carried out.

[0043] like Figure 4 As shown, by arranging a support plate 15 on the top of the push rod 9, arranging support rods 16 around the top thereof, and arranging a rubber cap 17 on the top of the support rod 16, when the push rod 9 is needed to support the seat board 7 for placing a dummy, the four positions at the bottom of the seat board 7 can be supported by the connected support rods 16, and the rubber cap 17 can increase the connection friction to prevent the upper seat board 7 from shaking and affecting the placement of the dummy, and does not affect the actual falling trajectory of the seat board when it falls, and does not affect the accuracy of the test, and by arranging a replaceable rubber cap 17, it is prevented that different degrees of wear due to different degrees of friction during long-term use, thereby preventing the different support angles that may affect the test accuracy, so that the rubber cap 17 can be replaced after a certain period of time, so as not to affect the accuracy of the experiment.

[0044] Working principle: First, by setting the adjustment column 3, the connector 4, the limiting hole 10, the limiting rod 11 and the limiting nut 12, and by sleeve-connecting the connector 4 on the adjustment column 3, a person can hold the connector 4 and move it on the adjustment column 3, so that the height of the seat plate 7 can be changed, so that tests at different heights can be performed. When the connector 4 needs to be fixed, the limiting rod 11 is passed through the connector 4 and the limiting hole 10, and the limiting nut 12 is used to lock both sides of the limiting rod 11 to prevent the limiting rod 11 from falling off during use, so that the practicality of the new tester can be enhanced, and it can be used when it is necessary to re-test. When repeating the test experiment, the support plate 15, the support rod 16 and the rubber cap 17 can be set. By setting the support plate 15 on the top of the push rod 9, setting the support rods 16 around the top thereof, and setting the rubber cap 17 on the top of the support rod 16, when the push rod 9 is needed to support the seat plate 7 and a dummy is placed, the four positions at the bottom of the seat plate 7 can be supported by the connected support rods 16, and the rubber cap 17 can be used to increase the connection friction to prevent the upper seat plate 7 from shaking and affecting the placement of the dummy, and it does not affect the actual falling trajectory of the seat plate when it falls, and does not affect the accuracy of the test.
