In addition, the distance between the ball seat 1 and the base 2 can be adjusted by adjusting the length of the screw.
In any of the above embodiments, the pull rod 9 and the return spring 4 are made of austenitic stainless steel, the ball seat 1, the base 2, the pressing plate 6 and the inserting and pulling key 10 are made of aluminum alloy, and an anodic oxidation layer is provided on the outer surface of the aluminum alloy. Therefore, the corrosion of seawater can be reduced, and the service life of each part such as the pull rod 9 is prolonged. The pull rod 9 and the return spring 4 are made of austenitic stainless steel materials, so that the strength and the toughness are better, and the long service life is kept under the working condition of repeated stress.
The underwater nonmagnetic plug-in type starting switch provided by the embodiment of the invention is made of nonmagnetic materials, and can meet the requirement of nonmagnetic characteristics of products. The underwater non-magnetic plug-in type starting switch enlarges the size of the ball seat 1 according to the size condition of fingers of a frogman after wearing the clothes, thereby being beneficial to pulling up operation; adopts a compact structure type, and solves the problems of salt accumulation and sand accumulation. By adopting the design of the plug-in key 10 and the reset spring 4, when the plug-in key 10 is pulled out, the reset spring 4 resets to cause the underwater nonmagnetic plug-in starting switch to be turned off, and the safety of personnel and underwater equipment during man-machine separation can be ensured.
As shown in figure 1, the underwater non-magnetic plug-in type starting switch is designed by adopting a T-shaped hollow structure. The ball seat 1 with the circular convex surface is arranged at the upper end of the T-shaped structure, so that the pull rod 9 can be conveniently pulled up, and the operation is facilitated. A dynamic sealing structure is designed at the central part of the T-shaped structure, and the sealing requirement of the pull rod 9 on the up-and-down reciprocating motion is met. The step in the middle of the pull rod 9 is provided with the reset spring 4 to abut against the step, after the pulling-out function on the upper part of the pull rod 9 is removed, namely the pulling-out key 10 is pulled out, the reset spring 4 provides the downward acting force of the pull rod 9, and the self-resetting requirement of the pull rod 9 is met. The T-shaped structure is only provided with the ball seat 1, the upper end of the pull rod 9 and the flange end of the T-shaped structure, and is contacted with seawater, so that the position of salt and sand accumulation is reduced. And the plug-in structure is different from the knob structure, so that the problem of wrong rotation direction is not easy to occur. The pull rod 9 is matched with a central hole of the T-shaped structure by adopting a dynamic seal fit tolerance, the gap is small, lubricating grease or lubricating oil provided by the oil storage tank 13 is filled, and the problem of salt and sand accumulation when the underwater non-magnetic plug-in starting switch is used underwater can be effectively solved.
