Description
Technical field
This utility model belongs to Aero-Space technical field of fastening, particularly relates to a kind of interlayer locking hidden type empty
Intracardiac lock threaded components.
Background technology
In the application of aerospace field, after each material interlayer fastens, often also need to through pipe-line system, electricity
Gas 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 a lot
High strength 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
Dismounting, can not reuse, and this just constrains the fastening of hollow interlayer；The mode of some interlayer locking employing one side buckle is tight
Gu, 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 cutting
Wound or damage；Rivet can also be used, but rivet is to be permanently fixed, can not fix again.Therefore, at certain
A little regions need being dismounted for multiple times, can't damaged composite material time, above-mentioned plain bolt nut cannot meet installation requirement,
Buckle, rivet can not meet installation requirement, need outer surface attractive in appearance more simultaneously, do not reach especially and want when needing to hide
Ask.The aspect such as security reliability all can not meet requirement, because its security reliability difference often results in Aero-Space spacecraft simultaneously
Flight safety coefficient 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, install
Process not damaged composite material, can being dismounted for multiple times and the high hidden type threaded components of security reliability.
Utility model content
This utility model provides a kind of simple in construction, can repeatedly tear open for solving technical problem present in known technology
Dress, inside be hollow-core construction, security reliability height, and will not the interlayer locking hidden type of damaged composite material matrix hollow interior
Lock threaded components.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: a kind of interlayer is locked
Tight hidden type hollow internal lock threaded components includes split nut in hidden type bidirectional helical, also includes being mountable to hidden type two-way
The tack dextrorotation hollow bolt at split nut two ends and tack derotation hollow bolt in screw thread；Described tack dextrorotation hollow bolt peace
Head derotation hollow bolt all includes the screw rod of hollow structure, and inside screw forms cavity, and screw rod one end is provided with butt end, screw rod
Being provided with external screw thread on outer wall, the external screw thread of described tack dextrorotation hollow bolt is dextrorotation external screw thread, and described tack derotation is hollow
The external screw thread of bolt is derotation external screw thread；Be respectively arranged with on the two ends inwall of split nut in described hidden type bidirectional helical with just
Rotation external screw thread and the dextrorotation female thread that matches of derotation external screw thread and derotation female thread；In hidden type bidirectional helical outside split nut
In the middle part of wall, hoop offers and multiple screws hole.
Advantage of the present utility model and good effect be: just can be tightened by threaded components or stubborn by screwing spanner in rotating
Pine, therefore can use with repeated disassembled and assembled；Owing to using hidden type hollow-core construction, outside sandwiched matrix, do not have boss, because of
Sandwiched matrix will not be caused damage when of this locking interlayer；Due to threaded components inner hollow, be beneficial to through other screws,
The parts such as bearing pin, pipe-line system, electric wiring communication system.
Preferably: described in screw the number in hole be 2-8.

Detailed description of the invention
For utility model content of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example detailed
Carefully it is described as follows:
Referring to Fig. 1, this utility model includes split nut 2 in hidden type bidirectional helical, also includes being mountable to hidden type
The tack dextrorotation hollow bolt 1 at split nut 2 two ends and tack derotation hollow bolt 3 in bidirectional helical.
Referring to Fig. 2, described tack dextrorotation hollow bolt 1 and tack derotation hollow bolt 3 all include the spiral shell of hollow structure
Bar, inside screw forms cavity 7, and screw rod one end is provided with butt end 6, and screw rod outer wall is provided with external screw thread, and described tack is just
The external screw thread of rotation hollow bolt 1 is dextrorotation external screw thread 4, and the external screw thread of described tack derotation hollow bolt 3 is derotation external screw thread 5.
Refer to Fig. 3, in described hidden type bidirectional helical, on the two ends inwall of split nut 2, be respectively arranged with spiral shell outer with dextrorotation
Dextrorotation female thread 8 that stricture of vagina 4 and derotation external screw thread 5 match and derotation female thread 9；In hidden type bidirectional helical outside split nut 2
In the middle part of wall, hoop offers multiple hole 10 that screws, and the wherein said number screwing hole 10 is 2-8.
Refer to Fig. 4, use above-mentioned interlayer locking hidden type hollow internal lock threaded components that sandwiched matrix is locked
Method, comprise the following steps: a, from one end of sandwiched matrix 11 insert tack dextrorotation hollow bolt 1, put into latent from the other end
Split nut 2 in concealed bidirectional helical, is further continued for inserting tack derotation hollow bolt 3；B, the interior spanner that screws is inserted into hidden type
In bidirectional helical split nut 2 to screw hole 10 internal, screw spanner in turning clockwise, by the tack dextrorotation hollow bolt at two ends
1 and tack derotation hollow bolt 3 tighten, sandwiched matrix 11 is in locking state；C, need dismantle threaded components time, screw interior
Spanner be inserted into split nut 2 in hidden type bidirectional helical to screw hole 10 internal, screw spanner, by two ends in rotating counterclockwise
Tack dextrorotation hollow bolt 1 and tack derotation hollow bolt 3 are unscrewed.
This utility model simple in construction, processing is simple, practical convenient, security reliability high；By screwing spanner in rotating
Just threaded components can be tightened or unscrew, therefore can use with repeated disassembled and assembled；Owing to using hidden type hollow-core construction, sandwiched matrix
Outside does not have boss, therefore sandwiched matrix will not be caused damage when of locking interlayer；Inside threaded components
Hollow, is beneficial to through parts such as other screws, bearing pin, pipe-line system, electric wiring communication systems.
While there has been shown and described that the embodiment that this utility model is optimal, for those of ordinary skill in the art
Speech, it is possible to understand that these embodiments can be carried out multiple change in the case of without departing from principle of the present utility model and spirit
