Highly-reliable fast locking mechanism

Abstract

The invention belongs to technical field of vehicle chassis and particularly relates to a highly-reliable fast locking mechanism. The left lower portion of a base is provided with a cavity, and the left upper portion of the base is provided with a semi-circular hole. The right upper portion of the base is provided with cavity, and the right lower portion of the base is provided with a slideway. A push-pull rod is horizontally disposed in the left cavity of the base. A short rod is connected with the handle. A sleeve is sleeved outside of a long rod. The sleeve is welded with a seal plate and then connected to the opening of the left cavity of the base. A lock block is connected to the tip of the long rod. A copper bush is located in the semi-circular hole. A pin hole is formed in the middle of a lock plate, and the lower side of the lock plate is provided with friction self-locking face. The upper side of the lock block is a friction self-locking face corresponding to the friction self-locking face of the locking plate. The bottom of the lock block is located on the slideway of the base. A pin is located in the pin holes of the base and the lock plate. A retaining block, a fixing bolt and a spring are located at the opening of the left cavity of the base. The hook at one end of a return spring is mounted on the push-pull rod. The hook at the other end of the return spring is mounted on a positioning strip located at the left opening of the base. A stop pin tip hole is in pin joint with a stop plate pin and located above the slideway of the base, and the other end of a stop pin is connected with a steel wire rope.

Description

technical field [0001] The invention belongs to the technical field of special vehicle chassis, and in particular relates to a highly reliable fast locking mechanism. Background technique [0002] The locking mechanism is the main connection between the chassis and the launch tube, and it is used on every launch vehicle, and its reliability directly affects the safety of the launch tube. The locking mechanism used in the past relies on the self-locking friction angle of the lock block to lock the lock disc. When the designed frictional self-locking angle is close to or greater than the theoretical critical frictional self-locking angle, it is easy to unlock the phenomenon, and there is no prevention of unlocking after the frictional self-locking failure. Emergency measures cannot guarantee the reliable locking of the structure; the locking state of the structure is not obvious and cannot be corrected in time; the one-way operating device is very inconvenient during use; all ...

The locking mechanism used in the past relies on the self-locking friction angle of the lock block to lock the lock disc. When the designed frictional self-locking angle is close to or greater than the theoretical critical frictional self-locking angle, it is easy to unlock the phenomenon, and there is no prevention of unlocking after the frictional self-locking failure. Emergency measures cannot guarantee the reliable locking of the structure; the locking state of the structure is not obvious and cannot be corrected in time; the one-way operating device is very inconvenient during use; all parts of the structure have not been protected, which is harmful to nature Environmental protection is poor

The above problems lead to a great security risk in this structure
