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.
