Abstract
A structure for connecting a locking nail cap and a stopping ring comprises the locking nail cap, the stopping ring and the sandwich layer board, wherein the nail foot of the locking nail cap is rectangular and is integrally connected with a nail cap to form the T-shaped locking nail cap; the stopping ring is a circular sheet; radial recesses are formed in the circumferential edge of a circular hole. Compared with the conventional structure, the structure provided by the utility model, is convenient to mount, demount and overhaul, improves the production efficiency and saves the cost. Since the structure is simple, the production and maintenance are very convenient, the quality consistency is good, and the quality is ensured.
Description
Technical field
The utility model relates to a kind of quick-detachable lock structure, is a kind of mode of structure of the connection of pinning cap and stopper ring, and object is that pinning cap and stopper ring are assemblied in after sandwich plate, pinning cap and the stopper ring phenomenon that all can not get loose.
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.Now corresponding product extrusion pressure is 200N left and right, and the extrusion pressure of this product is greater than 800N.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, 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.
This is simple in structure, can ensure the quality of products again.
Described a kind of pinning cap and the linkage structure of stopper ring composition comprise: pinning cap, stopper ring, sandwich plate, the nail pin of pinning cap is made as cylindrical shape, cylinder staple foot plate surface central authorities have hole, the one, weight reduction, the 2nd, enhance mechanical strength, cylinder staple pin is also connected as a single entity and forms T shape pinning cap with the head of a nail; Stopper ring is a circular piece, and circle center hole circle edge has radial recess on edge.When assembling, first pinning cap is packed in sandwich plate, stopper ring is packed into from the bottom of pinning cap with special assembly tooling, be then loaded into 180kN.
Adopt the beneficial effect of the technical program: compared with former mode of structure, have the following advantages:
1, mounting or dismounting are convenient, are convenient to aircraft maintenance, improved manufacturing efficiency, it simple in structure.
2, cost-saving, due to simple in structure, no matter produce, maintenance is all very convenient, and other all share.
3, quality of product high conformity, quality is guaranteed, and has not only ensured product requirement performance, and more than can also ensureing that extrusion pressure reaches 900N.
Brief description of the drawings
Fig. 1 is of the present utility model group of view.
Fig. 2 a, 2b, 2c are respectively the structural drawing of pinning cap, stopper ring, sandwich plate.
In figure: 1-pinning cap, 2-stopper ring, 3-sandwich plate.
Embodiment
The linkage structure of a kind of pinning cap described in the utility model and stopper ring, embodiment now contrasts accompanying drawing and explains, its structure composition comprises: pinning cap 1, stopper ring 2, sandwich plate 3, the nail pin of pinning cap 1 is made as cylindrical shape cylindrical shape, nail foot plate surface central authorities have hole, the one, weight reduction, the 2nd, enhance mechanical strength, cylinder staple pin is also connected as a single entity and forms T shape pinning cap with the head of a nail; Stopper ring 2 is a circular piece, and hollow circle center hole circle edge has radial recess and double wedge on edge.When assembling, pinning cap is packed in sandwich plate, stopper ring is packed into from the bottom of pinning cap with special assembly tooling, be then loaded into 180kN.Firmly be locked at the object that reaches fixing clamp laminate 3 on nail pin by the double wedge on stopper ring 2, radial recess and the double wedge of stopper ring 2 are made as symmetrical recess and double wedge.
