FIELD: transport engineering; antitheft devices. ^ SUBSTANCE: invention relates to stops of shaft and it can be used in vehicles as antitheft device and as lock to protect rooms. Proposed stop with lock mechanism has key made in form of plate with cavities for unlocking the mechanism. Stop of shaft consists of housing, barrel and catch. Housing and barrel are provided with pins arranged coaxially over circumference along axis. Pins of barrel are spring-loaded to form lock mechanism. Barrel is installed in housing for turning around axis, catch is rigidly installed in housing and cutouts for shaft are made in catch and in barrel. Central cylindrical hole is made in barrel to receive spring-loaded stepped piston engaging with pins by end face and cylindrical parts. Each pin consists of at least three parts: one part is stepped, engaging with key, the other is sectional, consisting of cylinder and rod for fixed change of length, and the last one engages with piston. ^ EFFECT: enlarged sphere of application, prevention of unauthorized unlocking of shaft stop. ^ 2 dwg |
