Embodiment Construction

[0032] The structure of the present invention includes a bolt and a hollow supporting plate, the tapered surface of the inner wall of the supporting plate is coaxial with the inner and outer cylindrical surfaces of the supporting plate, and the supporting plate is fixed to the plate or to another part, said Inside the pallet, there is an integral bush composed of a pair of half bushes with internal threads. When the bolt is inserted into the bush, the half bush is initially contracted to be smaller than the minimum active pitch diameter of the bolt by the action of the conical coil compression spring. , so that the bolt produces a locking torque. The angle of the taper surface of the outer surface of the half bushing is the same as that of the inner wall of the supporting plate, and the bushing also has a preferred internal thread structure, so as to be suitable for external threads similar to special bolts. This type of bolt is suitable for the fastening connection of two or ...

Abstract

The invention provides a one-half-revolution rapid-release locking device comprising a bolt and a supporting plate assembly. The supporting plate assembly comprises an end cover, a compression spring, a lock ring, a supporting plate and two half linings. The supporting plate is a hollow cylinder. A circumferential annular bulge is arranged on the inner wall of the supporting plate. The two half linings provided with inner threads form a cone-frustum-shaped lining in an enclosing mode, and the cone-frustum-shaped lining is mounted in an inner cavity of the supporting plate. The bulge on the inner wall of the supporting plate limits the movement range of the lining in the axial direction of the supporting plate. The compression spring compresses the lock ring between the end cover and the lining. Axial bulges of the lock ring limit circumferential rotation of the lining. When the bolt is inserted into the lining, the two half linings retract towards the axis under the effect of the compression spring, and thus locking torque to the bolt is generated. In all using states, the locking device can lock reliably, and firmness is guaranteed.

Description

technical field [0001] The invention relates to a locking device, which is used for quick connection of several layers of stacked boards. Background technique [0002] At present, in the aviation industry, the typical connection method of several layers of structural plates is to use a large number of double-wire, four-wire and other multi-wire bolts and nuts to quickly and reliably connect; figure 1 It is one of the structural forms. It includes a structural plate 1, a structural plate 2, a multi-thread nut 3, a retaining ring 4, a rivet 5, a double ratchet 6, a spring 7, a casing 8, a multi-thread bolt 9 and a bracket 10. Wherein the double ratchet 6, the spring 7 and the multi-wire bolt 9 are placed inside the shell 8, and then the thin wall of one end of the shell 8 is radially spun, and the three parts are assembled in the shell 8 to form a whole ( figure 1 (a)). There are 4 grooves on the outer cylindrical surface of the multi-thread nut 3, which are evenly distribu...
