Detailed Description
The utility model relates to a rotary adjustable acceleration control axial movement mechanism which mainly has the function of automatic locking. The length of the shoulder belt can be locked in time in an emergency, so that the upper trunk of a driver is firmly restrained at the original position, and the function of protecting the driver is achieved.
The utility model is further described below with reference to the accompanying drawings.
The rotary adjustable acceleration control axial movement mechanism is a retractor for the safety belt component of the passengers of the airplane, the appearance of which is shown in figure 1,
the inside transverse structure that is of rotatory adjustable acceleration control axial moving mechanism, one side outermost is outer brake plate 1, and inertia board 3 is connected with outer brake plate 1, and rotatory adjustable acceleration control axle 6 is located the inside central authorities of moving mechanism, and rotatory adjustable acceleration control axle 6 sets up near inertia board 3 and flies the nest groove, and part steel ball 2 imbeds and flies the nest inslot, is connected with inertia board 3 again. The outermost surface of the other side is provided with a spring box 10, a spring 9 is arranged in the spring box 10 and is connected with an inner brake plate 8, and a tower spring 7 is arranged between the rotary adjustable acceleration control shaft 6 and the inner brake plate 8; the telescopic belt 5 is arranged in the middle of the rotary adjustable acceleration control shaft 6. The outer brake plate 1, the steel ball 2, the inertia plate 3, the telescopic belt 5, the rotation adjustable acceleration control shaft 6, the tower spring 7, the inner brake plate 8, the spring 9 and the spring box 10 are covered by the shell 4, and the crimper component is formed together.
The details and operation of the specific apparatus proposed according to the present invention are described in detail with reference to fig. 2. When the extension band 5 on the shoulder strap is pulled out under the action of external force, the shaft 6 connected with the extension band rotates, when the pull-out acceleration of the extension band is small (below 1.5 g), the component force of the centrifugal force generated by the steel ball 2 on the inertia plate 3 is smaller than the spring force, the inertia plate 3 and the shaft 6 rotate synchronously without generating axial displacement, and the extension band 5 can extend and retract freely. When the pulling acceleration of the telescopic belt 5 reaches a certain value (more than 3.0 g), the component force of the centrifugal force generated by the steel ball 2 on the inertia plate 3 is larger than the spring force, the inertia plate 3 is pushed to move axially to be meshed with the outer brake plate 1, and the shaft 6 is pushed to move towards the other end to be meshed with the inner brake plate 8, so that the shaft 6 cannot rotate, the telescopic belt 5 cannot be pulled out continuously and is locked.
In summary, the rotation-adjustable acceleration-controlled axial movement mechanism of the present invention rotates the shaft connected to the shoulder strap when the extensible strap is pulled out by an external force, and allows the extensible strap to be extended and retracted freely when the acceleration of pulling out the extensible strap is small. When the pulling acceleration of the telescopic belt reaches a certain value, the telescopic belt can not be pulled out continuously and is locked. The mechanism utilizes the inertia mechanism to control the axial movement of the shaft assembly to be meshed with the inner brake plate, braking stress is generated, and as the end teeth are in overall contact, the stress condition is better, under the condition of ensuring specified strength, the requirement can be met by selecting hard aluminum alloy, so the quality is lower.
