Description

Fast lock screw connector

Technical field

The utility model 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, do not need to bear very big power, only do the zone that simply fixedly gets final product, when needing to be fixed on the 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 purpose of this utility model is: a kind of fast lock screw connector is provided, it can reduce carrying junctor member and manufacture difficulty, again can weight reduction, and the safety reliability height, a kind of fast lock screw connector easy to maintenance is to overcome the deficiencies in the prior art.

The utility model is achieved in that fast lock screw connector, comprises lock screw, is provided with inner hexagonal hole on the top of lock screw, is provided with orthohexagonal chock plug in inner hexagonal hole; Afterbody at lock screw is provided with the spring catch ring recess, is provided with check ring in the spring catch ring recess.

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, for transition sloping platform rank, is transition sloping platform rank II at the end of back cylindrical section between preceding cylindrical section and the back cylindrical section; The afterbody of lock screw is the chamfering boss, and at the chamfering boss and cross between the II of sloping platform rank and be provided with the spring catch ring recess, 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 1～4 head thread.

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 utility model adopts lock screw is inserted in the hole of double-layer structure panel, mounting spring back-up ring again, tighten to 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 exterior appearance of airplane parts design, flexible design and layout are to satisfy the attractive in appearance of interior of aircraft decoration; Advantages such as the utility model 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.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of lock screw of the present utility model;

Accompanying drawing 3 is a utilization structure schematic representation of the present utility model.

Embodiment

Embodiment of the present utility model: the structure when fast lock screw connector uses 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), its middle part is made as preceding cylindrical section 4 and back cylindrical section 5, be transition sloping platform rank 6 between preceding cylindrical section 4 and the back cylindrical section 5, produce transition sloping platform rank II 13 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 II 13, 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; Make 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, 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, at bolt 16(or the double-screw bolt on the base structure plate 15) on 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-bearing zones such as software thin plate connection, plain nut can't reach these regional installation functions, the utility model 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, check ring 3 is expanded to when excessive to play spacing on the transition sloping platform rank II 13 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, it is offside when the setting tool that prevents inner hexagonal hole 11 is installed to level and smooth cylindrical yielding groove 10 places, simultaneously can also block other foreign material and enter level and smooth cylindrical yielding groove 10, avoid foreign material to arrive multiple thread 9 places and make it that inconvenience is installed 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.
