Bearing quick-release lock

Abstract

The invention discloses a bearing quick-release lock and belongs to the fields of quick release connection of a fairing and an access panel which are frequently released in an aviation helicopter structure. The bearing quick-release lock is characterized by comprising a lock seat assembly and a lock pin assembly, wherein the lock seat assembly comprises a sealing cap, a snap spring, a compression spring, a sliding block and a lock seat; the lock pin assembly consists of a washer, a lock pin, a bush and an ejection rod. The bearing quick-release lock disclosed by the invention has the advantages of light structural weight, attractive appearance, high reliability, sealing property and certain bearing capacity, and can be suitable for quick release connection of a fairing at a position where the vibration environment is particularly severe. According to the quick-release lock disclosed by the invention, after locking, the lock pin is clamped by a clamping groove of the sliding block, so that the lock pin cannot extend by rotating; the lock pin can be unlocked by rotating after the ejector rod is pushed by a tool and is enabled to push the sliding block to move until the lock pin cannot be clamped by the sliding block; after locking, the ejector rod ejects to be in flush with the head of the lock pin, so whether the virtual locking exists or not can be effectively judged.

Description

technical field [0001] The invention belongs to the field of quick-release connection of fairings and mouth covers that are often disassembled in the structure of aviation helicopters, and relates to a quick-release lock structure. Background technique [0002] Helicopters have many moving parts and high vibration levels, and the vibration environment is particularly harsh at engine fairings, tail reducer fairings and other parts. Due to the frequent maintenance of the engine and tail reducer, the fairing needs to be disassembled frequently. Since the helicopter fairing is often complex in shape, considering the need for frequent disassembly and maintenance of the fairing and the structural size and weight of the connecting parts, the relationship between the fairing and the structure The spaces are often connected with small quick-release nails. Several kinds of quick-release nails used by several military and civilian helicopters currently in service have frequently encou...

AI Technical Summary

Problems solved by technology

Several kinds of quick-release nails used by several military and civilian helicopters currently in service have frequently encountered faults such as loosening, breaking, and ejection of the quick-release nails for the fairing, especially the quick-release of the fairing accessories for the engine fairing and tail reducer. If the nail hits the blade after it pops up, it will damage the blade, which will bring safety hazards and the consequences will be disastrous
