Abstract
The utility model relates to a spring locking mechanism which comprises a pin rod, a lock pin, a spring, a spring cover, a dowel, a dowel cap, a pin and a seat, wherein the spring is arranged along the circumference at the outer layer of the pin rod; the spring cover is arranged outside the spring and is provided with the dowel and the dowel cap; the dowel passes through a pin hole arranged in the pin rod by the spring cover; the lock pin is arranged on the top of the pin rod; the pin is arranged at the lower end of the pin rod; the lower end of the pin rod is blocked into a groove arranged in the seat by an inclined plane arranged on the seat; and the pin rod is in clamping fit with the seat through the pin to be fixed. The spring locking mechanism is convenient and fast to use and stable in performance, and does not have the phenomenon of clamping stagnation, difficult opening, closing and locking or failure caused by part deformation and displacement.
Description
Technical field
The utility model relates to the mechanical interlocking parts, relates in particular to the spring locking mechanism, is mainly used in Aeronautics and Astronautics mechanical device etc.
Background technique
Existing locking mechanism in actual use, functional during first the installation, but after use, because factors such as vibrations operations, time is slightly long, distortion just appears in some position, and fine motion or displacement cause locking mechanism clamping stagnation or partial destruction not to use, open and close the failure conditions such as locking difficulty, helicopter solves potential flight hazard with the research and development of adjustable spring locking mechanism, changes the situation of this field long import of China.
Summary of the invention
The purpose of this utility model provides a kind of spring locking mechanism, the formation of this spring locking mechanism comprises: pin rod, spring, spring shield and stand, outer periphery at pin rod is provided with spring, spring is provided with spring shield outward, and pin and lug cap are arranged on the spring shield, and pin penetrates in the pin hole on the pin rod by spring shield, the top of pin rod is provided with lock pin, the lower end of pin rod is provided with pin, and pin rod snaps in the groove in the stand by the inclined-plane on the stand, is realized fixing with the snap-fit of stand by pin.
Adopt the beneficial effect of the technical program: the situation that causes locking mechanism clamping stagnation, open locking difficulty or lost efficacy position distortion, displacement can not appear, in easy to use, quick, stable performance.
