Technical field
The invention belongs to Aero-Space technical field of fastening, particularly relate to a kind of interlayer locking hidden type hollow internal lock spiral shell
Stricture of vagina assembly, further relates to a kind of method using above-mentioned hidden type hollow internal lock threaded components just to lock sandwiched matrix.
Background technology
In the application of aerospace field, after each material interlayer fastens, often also need to through pipe-line system, electrically
Line communication system, other securing parts etc., therefore it is required that fastening interlayer inside is hollow-core construction.
Early stage uses tubular rivet to fix, but fixes aspect at composite and but can not use, due to the most high-strength
Degree composite is also high fragility, it is impossible to accepts the hammer riveting of rivet or presses, and when needing to change, tubular rivet but can not be dismantled,
Can not reuse, this just constrains the fastening of hollow interlayer；The locking of some interlayer uses the mode of one side buckle to fasten,
But buckle fastening is the most firm and protruding too many, the damage of material can be caused, and a lot of composite is to be not allow for incised wound
Or damage；Rivet can also be used, but rivet is to be permanently fixed, can not fix again.Therefore, exist
Some region needs being dismounted for multiple times, can't damaged composite material time, above-mentioned plain bolt nut cannot meet installation want
Asking, buckle, rivet can not meet installation requirement, need outer surface attractive in appearance more simultaneously, need to reach especially not when hiding
To requiring.The aspect such as security reliability all can not meet requirement simultaneously, because its security reliability difference often results in Aero-Space boat
The flight safety coefficient of it device is low and maintenance cost high.
For solving above-mentioned a series of difficult problems present in prior art, need a kind of hollow-core construction of R & D design, installation process
Not damaged composite material, can being dismounted for multiple times and the high hidden type threaded components of security reliability.
Summary of the invention
The present invention solves technical problem present in known technology and a kind of simple in construction is provided, can repeated disassembled and assembled, inside be
Hollow-core construction, security reliability are high, and will not the interlayer locking hidden type hollow internal lock screw thread group of damaged composite material matrix
Part.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of interlayer locking is with hiding
Formula hollow internal lock threaded components includes split nut in hidden type bidirectional helical, also includes being mountable to hidden type bidirectional helical internal lock
The tack dextrorotation hollow bolt at nut two ends and tack derotation hollow bolt；Described tack dextrorotation hollow bolt and tack derotation are empty
Heart bolt all includes the screw rod of hollow structure, and inside screw forms cavity, and screw rod one end is provided with butt end, on screw rod outer wall
Being provided with external screw thread, the external screw thread of described tack dextrorotation hollow bolt is dextrorotation external screw thread, described tack derotation hollow bolt
External screw thread is derotation external screw thread；Spiral shell outer with dextrorotation it is respectively arranged with on the two ends inwall of split nut in described hidden type bidirectional helical
Dextrorotation female thread that stricture of vagina and derotation external screw thread match and derotation female thread；In hidden type bidirectional helical in the middle part of the outer wall of split nut
Hoop offers and multiple screws hole.
Advantages of the present invention and good effect be: just by screwing spanner in rotating can be tightened by threaded components or unscrew, therefore
Can use with repeated disassembled and assembled；Owing to using hidden type hollow-core construction, do not have boss outside sandwiched matrix, therefore lock
Sandwiched matrix will not be caused damage when of interlayer；Due to threaded components inner hollow, be beneficial to through other screws, bearing pin,
The parts such as pipe-line system, electric wiring communication system.
Preferably: described in screw the number in hole be 2-8.
It is a further object to provide and a kind of use the hidden type hollow internal lock threaded components of said structure to interlayer base
The method that body carries out locking.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of use above-mentioned interlayer lock
Tight hidden type hollow internal lock threaded components carries out the method locked, and comprises the following steps: a, from one end of sandwiched matrix insert
Enter tack dextrorotation hollow bolt, put into hidden type bidirectional helical split nut from the other end, be further continued for inserting tack derotation hollow
Bolt；B, by interior screw that spanner is inserted into split nut in hidden type bidirectional helical screw inside hole, turn clockwise inward turning
Twisting spanner, tack dextrorotation hollow bolt and the tack derotation hollow bolt at two ends are tightened, sandwiched matrix is in locking state；
C, when needing to dismantle threaded components, by interior screw that spanner is inserted into split nut in hidden type bidirectional helical screw inside hole,
Screw spanner in rotating counterclockwise, tack dextrorotation hollow bolt and the tack derotation hollow bolt at two ends are unscrewed.
