The tail part of the lock screw is provided with a spring collar slot, and a spring collar is arranged in the spring collar slot. In the structure of the fast lock screw connecter, the lock screw is inserted into holes of multiple layers of structural slabs, and then the spring collar is installed and is tightened on a bolt by using an internal hexagonal hole installation tool. With the structure, the action of fast locking the multiple layers of structural slabs can be achieved, and the beautiful external appearance and the flexible design and arrangement of aircraft parts can be satisfied so as to meet the appearance of aircraft interior decoration. The fast lock screw connector can substitute certain rivet nuts, has the dual functions of bolts and nuts, and has the advantages of simple structure, easy manufacturing, good use effect and the like.
Description
Technical field
The present invention relates to a kind of fastening piece, especially a kind of fast lock screw connector that is used for.
Background technique
At present, in the airplane parts design, the zone that some influences are attractive in appearance; Need not bear very big power; Only do the zone that simply fixedly gets final product, need be fixed on the last time of outer load-carrying construction spare of aircraft simultaneously, do not allow the connection of threaded portion because of the structural fatigue design criterion; Use common bolt and nut to connect simultaneously and cause installation inconvenient quick, interior trim is not attractive in appearance; And the inapplicable system screw thread of some nonmetal structure spares comes to be fastenedly connected with plain bolt; Have only 1/2nd to change or littler rotation space for some small spaces; Bolt or double-screw bolt are installed in the connection of some sandwich plate structural member, decorative layer connecting plate structural member are arranged again, can't accomplish that with plain nut and Insert Nut fast lock is connected at the bolt or the double-screw bolt outside.
Summary of the invention
The objective of the invention is: a kind of fast lock screw connector is provided; It can reduce carries junctor member and manufacture difficulty, again can weight reduction, and also safety reliability is high; A kind of fast lock screw connector easy to maintenance is to overcome the deficiency of existing technology.
The present invention is achieved in that fast lock screw connector, comprises lock screw, is provided with inner hexagonal hole on the top of lock screw, in inner hexagonal hole, is provided with orthohexagonal chock plug; Afterbody at lock screw is provided with the spring catch ring recess, in the spring catch ring recess, is provided with check ring.
The head of lock screw is flat round end or countersunk head.
The middle part of lock screw is preceding cylindrical section and back cylindrical section, is transition sloping platform rank between preceding cylindrical section and the back cylindrical section, and the end of cylindrical section is transition sloping platform rank II in the back; The afterbody of lock screw is the chamfering boss, between chamfering boss and transition sloping platform rank II, is provided with the spring catch ring recess, and check ring falls into the spring catch ring recess.
On the afterbody of lock screw and back cylindrical section, be provided with multiple thread, on preceding cylindrical section, be provided with level and smooth cylindrical yielding groove.
Multiple thread is for being less than or equal to 4 head threads.
Be provided with slideproof tooth in the inner hexagonal hole of lock screw.
It between chock plug and the inner hexagonal hole Spielpassung.
Owing to adopted technique scheme, compared with prior art, the present invention adopts lock screw is inserted in the hole of double-layer structure panel; Mounting spring back-up ring again; Tighten to the structure on the bolt with the inner hexagonal hole setting tool, reach the effect of fast lock double-layer structure panel, and can satisfy the outer aesthetic of airplane parts design; Flexible design and layout are to satisfy the attractive in appearance of interior of aircraft decoration; Advantages such as the present invention is the use of alternative some Insert Nut also, has the dual functions of screw bolt and nut, has simple in structurely, makes easily, and using effect is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of lock screw of the present invention;
Accompanying drawing 3 is a utilization structure schematic representation of the present invention.
Embodiment
Embodiments of the invention: the structure when fast lock screw connector uses is as shown in Figure 1; Produce lock screw 1 earlier, the head 17 of lock screw 1 is made as flat round end (also can be made as countersunk head), cylindrical section 4 and back cylindrical section 5 before the center is made as; Be transition sloping platform rank 6 between preceding cylindrical section 4 and the back cylindrical section 5; Produce transition sloping platform rank II13 at the end of cylindrical section 5, the afterbody of lock screw 1 is made as chamfering boss 7, between chamfering boss 7 and transition sloping platform rank II13, make spring catch ring recess 8; On the afterbody of lock screw 1 and back cylindrical section 5, produce multiple thread 9; On preceding cylindrical section 4, produce level and smooth cylindrical yielding groove 10, inner hexagonal hole 11 is produced on the top of lock screw 1, and on the inner face of inner hexagonal hole 11, produced slideproof tooth 12; Process circular check ring 3 with the spring thread material; Make the chock plug 2 of orthohexagonal plate construction again.
In use; Drilling on double-layer structure panel 14 earlier, the preceding cylindrical section 4 at the middle part of its aperture and lock screw 1 and back cylindrical section 5 are complementary, and chock plug 2 is inserted in the inner hexagonal hole 11 of lock screw 1; Tail end with lock screw 1 inserts in the hole of double-layer structure panel 14 again; And check ring 3 packed in the spring catch ring recess 8 of lock screw 1, to aim at bolt or the double-screw bolt on the base structure plate 14, on the bolt on the base structure plate 15 16 (or double-screw bolt), be shaped on multi-thread head thread with the identical screw thread of fast lock screw; Tighten inner hexagonal hole 11 with the setting tool of inner hexagonal hole 11, thereby fast lock screw is coupled together double-layer structure panel 14.
In some special zone that is not easy to install; Or even some narrow space very, non-bearings such as software thin plate connection zone, plain nut can't reach these regional installation functions; The present invention has the dual functions of screw bolt and nut concurrently, thereby solves these regional connectivity problems.
In order to improve using effect, can also be at the transition sloping platform rank 6 place's mounting spring packing rings between preceding cylindrical section 4 and the back cylindrical section 5; The afterbody of lock screw 1 is that chamfering boss 7 is to install in order to be easy to; Behind spring catch ring recess 9 places assemblings check ring 3, make when excessive check ring 3 be expanded to transition sloping platform rank II13 to go up and play spacing when tightening operation; Multiple thread 9 at afterbody can improve installation rate, and, on preceding cylindrical section 4, produce level and smooth cylindrical yielding groove 10 for the ease of processing; Slideproof tooth 12 at inner hexagonal hole 11 can prevent chock plug 2 slippages, and increases the frictional force of inner hexagonal hole 11 setting tool; Because lock screw 1 is when manufacturing inner hexagonal hole 11; It is the structure that it is made as through hole; Therefore the purpose of assembling chock plug 2 is blocked this through hole exactly in inner hexagonal hole 11; Offside when the setting tool that prevents inner hexagonal hole 11 is installed to level and smooth cylindrical yielding groove 10 places, can also block other foreign material simultaneously and get into level and smooth cylindrical yielding groove 10, avoid foreign material to arrive multiple thread 9 places and make its inconvenient installation or make multiple thread 9 impaired; When adopting chock plug 2, between its edge and the inner hexagonal hole 11 certain slit is arranged, air overflows from the edge of chock plug 2 when making installation lock screw 1, so that install.
