Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the piston is subject to vibration, gravity, air pressure disturbance and other factors during the transportation process, which may cause the action rod to move axially, resulting in accidental opening of the insurance and making the insurance invalid. A reset mechanism and a tube-mounted fuse adopting the reset mechanism

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment content of the present invention is described in further detail:

[0029] like Figure 1-Figure 3 As shown, a tube-mounted fuse equipped with a reset mechanism includes a housing, a base 11 , a piston 1 located in the housing, an energy storage compression spring 2 , an action pull rod 3 , and a reset mechanism located in the base 11 .

[0030] The base 11 provides the installation position for the reset mechanism through the lower end of the housing installed by bolts; There are O-ring seals between them.

[0031] The return mechanism includes two return pull rods 7 , two return springs 8 and a plug roller assembly 4 .

[0032]The plug roller assembly 4 includes a plug 13, a mandrel 12, a roller 14 and a roller auxiliary piece. The plug 13 is in an inverted Y shape, including a main rod and two support rods located at the lower end of the main rod; the upper end of the main rod is in contact with...

Abstract

The invention provides a reset mechanism and a tubing protector adopting same, and solves the problems that in a transportation process of an existing tubing protector, a piston is subjected to vibration, gravity, barometric disturbance and other factors, so that an action pull rod can move axially, the protector is opened accidentally, and the protector loses efficacy. The reset mechanism is mounted in a base at the lower end of a tubing protector shell and comprises a mandrel, two reset pull rods, two reset springs and a plug roller assembly, wherein the plug roller assembly comprises a plug, a mandrel and a roller; the upper end of the plug is in contact with the lower end of a tubing protector action pull rod; the roller is mounted at the lower end of the plug through the mandrel; two reset mechanism mounting cavities are formed in the base, and are stepped holes which comprise a first stepped hole and a second stepped hole; the reset pull rods are vertically arranged in the reset mechanism mounting cavities, and the lower ends are connected to the two ends of the mandrel; and the rod bodies, located in the first step hole, of the reset pull rods are sleeved with reset springs.

Description

technical field [0001] The invention belongs to the technical field of safety mechanisms of underwater self-launching devices, and relates to a reset mechanism and a tube-mounted safety device using the reset mechanism. Background technique [0002] The tube-mounted safety device is a device that can be ignited and started in time after the tube is launched underwater to ensure that the starting device cannot be ignited and started during storage and transportation. [0003] The tube-mounted fuse has two action states of closing and opening, which make the fuse close and open respectively; when the fuse is closed, it can cut off the starting control air circuit and the starting circuit, so that the starting device is in a locked state to prevent false start; when the fuse is opened, it is released The locking of the starting control air circuit and the starting circuit enables the starting device to start normally. The piston of the tube-mounted safety device is supported o...
