Abstract
The utility model discloses a dedicated load quick disassemble lock, comprising a bolt (1), wherein, the length of the bolt (1) is 12 mm; a heteromorphic spring groove (2) is formed on the bolt (1); a heteromorphic spring (3) is mounted in the heteromorphic spring groove (2); a lower lock body (4) is connected to the lower part of the bolt (1); and a bush (5) is arranged on the lower side of the bolt head (6) of the bolt (1). The quick disassemble lock operates by forming a groove on the bolt, mounting a heteromorphic spring, and rotating the lower lock body to generate elastic potential energy deformation. The structure has the advantages that not only the quick disassembly can be realized, but also the reliability after the assembly is good, and the locking effect is superior. The quick disassemble lock further has the advantages of simple structure, easy manufacture, good use effect and the like.
Description
Technical field
The utility model relates to a kind of fastening piece, especially a kind of special-purpose load quick-release lock.
Background technique
At present, some local thinner thicknesses of the interlayer of aircraft, and assembly space is restricted, is difficult to assemble with conventional fit, and the speed of equipment is slow, and assembly precision requires high, and maintenance is inconvenient, anti-loosening property and load performance are good inadequately, and volume is bigger, have also increased the weight of aircraft assembling.
The model utility content:
The purpose of this utility model is: a kind of special-purpose load quick-release lock is provided, and it can realize fast quick-detach, and has alleviated the weight of aircraft assembling, to overcome the deficiencies in the prior art.
The utility model is achieved in that special-purpose load quick-release lock, and it comprises bolt, is provided with the deformed spring groove on bolt, and a deformed spring is housed in the deformed spring groove, is connected with a down lock body in the bottom of bolt.
Bolt head downside at bolt is provided with a lining.
Be provided with a cross recess in the bolt head top.
Be provided with a stopper ring that is enclosed within on the bolt below the lining.
The thread section of bolt is a Full Thread FT, and its worm structure is a double-start thread made in U.S.A.
The length of bolt is 12mm.
The down lock body that connects in the bottom of bolt is a Full Thread FT, and length is 7.3mm.
Owing to adopted technique scheme, compared with prior art, the utility model adopts and slots on bolt, and a special-shaped spring is installed, rotation generation elastic potential energy distortion by down lock body is worked, such structure not only can realize fast quick-detach, and the good reliability after installing, and has good locking effect.Advantages such as the utility model also has simple in structure, produces easily, and using effect is good.
Description of drawings
Accompanying drawing 1 is a utilization structure schematic representation of the present utility model;
The plan view that accompanying drawing 3 for accompanying drawing 2 is;
Accompanying drawing 4 is the structural representation of cross recess 7.
Embodiment
When assembling, bolt 1 is passed flaggy 9, glue-line 10 and following flaggy 11, by rivet 12 down lock body 4 is fixed on down on the flaggy 11, bolt 1 bottom is passed down lock body 4 and is connected, bolt head 6 downside mounting bush 5 at bolt 1, the bottom of lining 5 is fixed in the flaggy 9, and a stopper ring 8 is installed between bolt below the lining 51 and glue-line 10.
The environment that bolt 1 uses has determined that bolt 1 will have higher fatigue strength, the groove of hexagonal structure in if the bolt head of bolt 16 continues to adopt, its mechanical property is difficult to guarantee so, thereby change hexagonal structure in the bolt head 6 into cross recess 7, effectively control cross recess 7 degree of depth, this structure had both guaranteed the mechanical property requirement, satisfy the clamping needs again, core of the present utility model position is the special-shaped spring 2 that is assemblied on the bolt 1, abnormity spring 2 is worked by the rotation generation elastic potential energy distortion of down lock body 4, require special-shaped spring 2 that better and moderate resiliently deformable is arranged in bolt 1, and the length of bolt 1 has only 12mm, this project organization mode not only can reach the effect of fast quick-detach, has also alleviated the weight of aircraft assembling.
In the process of assembling, strut the self-locking position of nut by bolt 1, make it produce resiliently deformable and have self-locking property.The self-locking performance that is obtained has stable, lasting resiliently deformable.Simultaneously, the stopper ring 8 on the bolt 1 has also played quick stop, thereby connected piece can be firmly fixed, and has good locking effect.
