Abstract
A rapid detachment lock nail used for aircraft is composed of a lock nail body and a stopper ring, wherein the lock nail body is composed of a lock nail cap and a lock nail main body. A workpiece interlayer plate serves as an installation piece. One end of the lock nail body is provided with the cylindrical lock nail main body. A hole is formed in the bottom face of the cylindrical lock nail main body. The top end of the cylindrical lock nail main body and the lock nail cap are connected into a whole to form the T-shaped lock nail body. The inner circle aperture of the lock nail cap is larger than the outer diameter of the cylindrical lock nail main body. The lock nail cap and the upper opening edge of a cylinder of the lock nail body are connected with each other in a right-angle mode. The stopper ring is a circular ring, wherein symmetrical notches are formed in the circumferential edge of an inner hole of the ring, and protruding teeth arranged at intervals together with the notches are arranged on the circumferential edge of the inner hole of the ring. The stopper ring is arranged in the lock nail main body from the bottom of the lock nail main body through a special assembly tool, loading is conducted till the force reaches 180 KN, and therefore the protruding teeth of the stopper ring generate interference deformation on the circumference of the lock nail main body and are then fastened in the workpiece inter layer. Compared with an existing structure, the rapid detachment lock nail has the advantages of being convenient to detach, convenient to overhaul, capable of improving production efficiency and saving cost, simple in structure, convenient to produce and contain, good in quality consistency and capable of ensuring quality.
Description
Technical field
The present invention relates to a kind of connection locking structure of handling fast, especially relate to a kind of for carry-on quick handling pinning.
Background technique
Domestic-developed has many types to unload lock construction at present, but much quality all can not be guaranteed, and can not meet the technical requirements of ASM5591, and aircraft is caused to immeasurable consequence.Existing corresponding product extrusion pressure is 200N left and right, and the extrusion pressure of this product is greater than 800N.Can meet the fixing requirement of pinning of various aircraft completely.
Summary of the invention
The object of this invention is to provide a kind of simple in structurely, can ensure the quality of products again, thereby solve the deficiency of various corresponding products.Meet extrusion pressure and be greater than 800N.Thereby ensured the safety of aircraft, and open and close lock is more convenient.Can ensure the quality of products again.
Described one comprises for carry-on quick handling pinning composition: pinning, stopper ring, pinning are made up of pinning cap, pinning body, sandwich plate is installing device, one end of pinning is cylinder nail, cylindrical shape rivet nut bottom surface central authorities have hole, with weight reduction, enhance mechanical strength, the top of cylindrical shape rivet nut and pinning cap are connected as a single entity and form T shape pinning, the outer annulus edge of pinning cap is along being bent into slope downwards, the interior circular hole internal diameter of pinning cap is greater than the external diameter of cylindrical lock rivet nut, and is at right angles connected with pinning cylindrical shell upper edge; Stopper ring is a circular ring, and ring endoporus circle edge is along above having the double wedge that symmetrical recess and recess are alternate.When assembling, pinning is packed into and installed in workpiece sandwich plate, by special assembly tooling, stopper ring is packed into from the bottom of pinning body, be then loaded into 180KN, make stopper ring produce interference distortion and the object of fastening installation workpiece sandwich plate at the circumference of pinning body.
Adopt the beneficial effect of the technical program: compared with former mode of structure, there are mounting or dismounting convenient, be convenient to aircraft maintenance, improve manufacturing efficiency, it simple in structure, cost-saving, produce, keep in repair easily, quality of product high conformity, quality assurance product to aircraft performance requirement, more than ensureing that extrusion pressure reaches 900N.
