Description

Technical Field

[0001] The utility model belongs to the technical field related to mechanical engineering, and specifically relates to an air bag tensioning mechanism. Background Art

[0002] The airbag tensioning mechanism achieves the purpose of tensioning by regulating the air pressure inside the airbag. When compressed air or gas is injected into the airbag, the airbag will expand and push the mechanical device to a tensioned state; when the air pressure is released, the airbag will contract and relax the mechanical device.

[0003] However, when the existing airbag tensioning mechanism is in use, the pressure on the airbag material changes over time. When compressed air or gas is injected into the airbag, the volume of gas injection remains unchanged, and the size of the airbag's expansion and contraction becomes increasingly unstable.

[0011] Preferably, a joint is provided at a position below the mounting seat, and two joints are provided in the joint array, and two are provided on the left and right sides of the mounting plate respectively.

[0012] Preferably, the platform and the adjustment plate are steel structures, and four springs A are arranged in an annular array.

[0013] Compared with the prior art, the utility model provides an airbag tensioning mechanism, which has the following beneficial effects:

[0014] 1. Through the arrangement of spring B, sealing ring, sealing ring, pressure block, slider, slideway, spring A, block B and block A, the sealing ring and sealing ring can disperse the pressure generated by the gas, thereby reducing the pressure on a single seal, thereby reducing the wear of the sealing ring or the sealing ring and increasing its service life. Furthermore, arranging the sealing ring and sealing ring at the same time can provide better adaptability, so that the connection between the cylinder and the airbag can still maintain good sealing performance even under different conditions. The cylinder moves upward, compressing spring B, and the connecting rod drives the top inclined block to move upward. The inclined block pushes the slider to move outward, and the pressure block moves outward accordingly, thereby achieving the purpose of stably tightening the airbag.

[0015] 2. Through the arrangement of the guide shaft, top shaft, top block, cylinder and mounting plate, when the connecting rod drives the top inclined block to move upward, the movement trajectory of the inclined block can be positioned by the guide shaft arranged at the bottom position of the spring B to prevent deviation. At the same time, the top block arranged at the position below the top shaft will limit the movement distance of the connecting rod to prevent the connecting rod from derailing and causing mechanical failure. The mounting plate arranged in an array at the position above the cylinder connects and fixes the bottom cylinder with the upper mounting seat, thereby reducing the impact of vibration during cylinder movement on the device and improving the service life of the device.

[0031] In this embodiment, the utility model is specifically an airbag tensioning mechanism. The device to be fixed is placed in the airbag tensioning mechanism, and the bottom cylinder 17 is started. The cylinder 17 moves upward, compressing the spring B22. The connecting rod drives the top inclined block to move upward. The inclined block pushes the slider 5 to move outward in the slide 6. At the same time, the slider 5 will push the end stopper B to compress the internal spring B21, so that the device can stably shrink the airbag.

At the same time, the top block 14 arranged at the position below the top shaft 10 will limit the movement distance of the connecting rod to prevent the connecting rod from derailing and causing mechanical failure. The mounting plate 12 arranged in an array at the position above the cylinder 17 connects and fixes the bottom cylinder 17 to the upper mounting seat 2, while reducing the impact of vibration during the movement of the cylinder 17 on the device, thereby improving the service life of the device.
