Abstract

The invention relates to mechanical engineering and can be used in devices that secure and unlock movable elements. The purpose of the invention is to increase the operational reliability and ensure reusability without replacing the components. The check is provided with a retainer 4 placed inside the body 1 and made in the form of a truncated cone of elastic material reinforced with elastic elements along the generator. The housing is equipped with a nut 6 with a protrusion 7, which interacts with the piston 2 having an annular groove 12. The mating surfaces of the protrusion of the nut and the piston are made in the form of cones. When a gas drive is triggered, the gases entering through the bypass channels create pressure in the body cavity. The latch disengages the piston, which, moving inside the housing, ensures the rod is disengaged from the actuator. At the end, the piston hits the conical surface of the conical surface of the nut, ensuring that its kinetic energy is quenched and jammed due to the elastic deformation of the protrusions. 2 Il.

Description

The invention relates to machine-building, namely to devices providing fixation and release of moving elements.

The purpose of the invention is to increase the operational reliability and ensure reusability without replacing the components.

FIG. 1 shows the proposed check; in fig. 2 is a section A-A in FIG. one.

the latch 4 is pressed against the surface 17 and unlocks the piston 2, which, being mixed, and inside the housing, provides for the withdrawal of the rod 3 from engagement with the actuator with the body.

At the end of the stroke, the piston 2 hits the conical surface 9 against the surface 8 of the nut 6, ensuring that its kinetic energy is extinguished and jammed due to the elastic deformation of the projections 7 and 13. Auxi-Chek contains a housing 1, inside of which the pinching angle 2 depends on the angle of jamming rod 3, and locking the mating surfaces 8 and 9.

Invention Formula The check contains a housing with a piston rod 20, made with a gas chamber and bypass channels, a gas drive, characterized in that, in order to increase operational reliability and ensure reusability without replacement of components, it is provided with a lock made of elastic reinforced material along the material forming elastic elements placed in the housing and contacting the peripheral and internal surfaces with the housing 30 and the stem, respectively, with a protrusion nut mounted on the housing the protrusion of the nut is made with a conical inner surface, the piston is made with an annular groove and the outer conical top. In the initial state, the piston 2 is displaced to the lowest position, and the rod 3 is engaged with an actuator (not shown). When this latch 4, interacting with the grooves 6 of the rod 3, the elements 16 keeps the piston from spontaneous movement when exposed to dynamic loads and overloads in the axial direction. The check works as follows. When gas actuated 11 The check contains a housing with a piston rod 20, made with a gas chamber and bypass channels, a gas drive, characterized in that, in order to increase operational reliability and ensure reusability without replacement of components, it is provided with a lock made of elastic reinforced material along the material forming elastic elements placed in the housing and contacting the peripheral and internal surfaces with the housing 30 and the stem, respectively, with a protrusion nut mounted on the housing , the protrusion of the nut is made with a conical inner surface, the piston is made with an annular groove and an outer conical surface 25 By returning the ducts through the channels 10, the return surface of the protrusion creates 5 ki, and the fixing element has that pressure in the cavity a of the housing 1. In this case, the strut shape. the retainer 4 is pressed against the surface 17 and unlocks the piston 2, which, being mixed, and inside the housing, provides for the withdrawal of the rod 3 from the engagement with the actuator. At the end of the stroke, the piston 2 hits the conical surface 9 against the surface 8 of the nut 6, ensuring that its kinetic energy is extinguished and jammed due to the elastic deformation of the projections 7 and 13. The jamming force depends on the angle of the cone — the possibility of its repeated use without replacing the elements.
