Description

A kind of stealthy bolt
Technical field
The invention belongs to bolt technical fields, and in particular to a kind of stealthy bolt.
Background technique
With the development of science and technology, higher and higher, stealthy principle is required mainly to fly the stealthy of present opportunity of combat Microwave absorbing coating is coated in machine outer surface, if aircraft surfaces is uneven, it will influence the Stealth Fighter of aircraft.At present in aircraft The dormant bolt used on covering, although preferably being controlled according to matching requirements enemy molded dimension, twisting slot it is recessed Sunken place affects the globality on aircraft skin surface, uneven so as to cause aircraft surfaces, directly affects the stealthy of aircraft Performance.So being badly in need of developing a kind of bolt, to guarantee that aircraft surfaces are smooth after installation, improve the Stealth Fighter of aircraft.
Summary of the invention
To solve the above problems, the object of the present invention is to provide a kind of stealthy bolt, twisting slot is in envelope when not in use Closed state, when twisting, shows twisting slot again under twisting instrumental purpose, to meet novel invisbile plane machine entire surface It is required that.
A kind of stealthy bolt, including bolt body, plug and spring, the bolt body are dormant bolt, the bolt The twisting groove of ontology is interior six square groove, and the twisting bottom portion of groove is equipped with blind hole, is equipped between the twisting groove and blind hole Connecting hole, the aperture of the connecting hole are less than the aperture of the blind hole；The plug is by shape and twisting groove nominal dimension phase Same outer six sides blanking cover and cylinder composition, the outer diameter of the cylinder is identical as the internal diameter of the connecting hole, the bottom of the cylinder Portion is equipped with projecting platform, and the outer diameter of the projecting platform is greater than the outer diameter of the cylinder and is less than the internal diameter of the blind hole, the cylinder Several elastic grooves are in axial direction equipped with, the spring is set between the plug and blind hole.
For the elasticity for guaranteeing cylinder, the quantity of the elastic groove is six, and is evenly arranged on the cylinder.
To be inserted into blind hole convenient for cylinder, the projecting platform is that taper hangs upside down platform.
The stealthy bolt of the present invention, compared with prior art, the beneficial effect is that: 1. the configuration of the present invention is simple, performance with Existing bolt product is identical, achievees the effect that flush with aircraft surfaces after assembly, substantially increases the stealth of aircraft surfaces Energy；2. the present invention facilitates manufacture, use is also more convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the stealthy bolt of the present invention；
Fig. 2 is the structural schematic diagram of bolt body in the stealthy bolt of the present invention；
Fig. 3 is the structural schematic diagram of plug in the stealthy bolt of the present invention；
Fig. 4 is the right view of Fig. 3.
As shown in the figure, 1- bolt body, 2- plug, 3- spring, 4- twisting groove, 5- connecting hole, 6- blind hole, 7- blanking cover, 8- cylinder, 9- hang upside down platform, 10- elastic groove.
Specific embodiment
Principles and features of the present invention are described with reference to embodiments, illustrated embodiment is served only for explaining this hair It is bright, it is not intended to limit the scope of the present invention.
As shown in Figs 1-4, a kind of stealthy bolt, including bolt body 1, plug 2 and spring 3, the bolt body 1 is heavy Hook bolt, the twisting groove 4 of the bolt body 1 are interior six square groove, and 4 bottom of twisting groove is equipped with blind hole 6, the twisting Connecting hole 5 is equipped between groove 4 and blind hole 6, the aperture of the connecting hole 5 is less than the aperture of the blind hole 6；The plug 2 by Shape outer six side's blanking covers 7 identical with 4 nominal dimension of twisting groove and cylinder 8 form, the outer diameter of the cylinder 8 and the company The internal diameter for connecing hole 5 is identical, and the bottom of the cylinder 8 is equipped with projecting platform 9, and the projecting platform 9 is that taper hangs upside down platform, and projecting platform 9 Outer diameter be greater than the outer diameter of the cylinder 8 and be less than the internal diameter of the blind hole 6, the cylinder 8 is in axial direction set there are six bullet Property slot 10, and be evenly arranged on the cylinder 8, the spring 3 is set between the plug 2 and blind hole 6.
The present invention is achieved in the following ways: when assembly, first in blind hole 6 be packed into spring 3, then by blanking cover 7 with Twisting groove 4 is aligned, and plug 2 is pressed into twisting groove 4, so that the projecting platform 9 of cylinder 8 enters in blind hole 6, in elastic groove 10 Under the action of, groove width is restored to original size, is fixed on plug 2 in connecting hole 5, and make 7 end of blanking cover under the action of spring 3 Face and bolt end face, thus after ensure that assembly aboard, the planarization of aircraft surfaces；In use, by tool pair Just backward 4 internal pressure plug of twisting groove, to make twisting groove 4 expose, convenient for the installation or taking-up of bolt.
Protection scope of the present invention is not limited to technical solution disclosed in specific embodiment, all skills according to the present invention Art any modification, equivalent substitution, improvement and etc. substantially to the above embodiments, each fall within protection scope of the present invention.
