Description
Technical field
The utility model belongs to bolt technical field, 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.
Utility model content
To solve the above problems, the purpose of the utility model is to provide a kind of stealthy bolt, twisting slot is located when not in use
Twisting slot is showed, again under twisting instrumental purpose when closed state, twisting to meet novel invisbile plane machine entire surface
The requirement of property.
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 utility model, compared with prior art, the beneficial effect is that: 1. the utility model structure letters
Single, performance is identical as existing bolt product, achievees the effect that flush with aircraft surfaces after assembly, substantially increases aircraft surfaces
Stealth Fighter；2. the utility model facilitates manufacture, use is also more convenient.

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
The principles of the present invention and feature are described with reference to embodiments, illustrated embodiment is served only for explaining this
Utility model is not intended to limit the scope of the utility model.
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 utility model is achieved in the following ways: when assembly, spring 3 is first packed into blind hole 6, then by blanking cover
7 are aligned with twisting groove 4, and plug 2 is pressed into twisting groove 4, so that the projecting platform 9 of cylinder 8 enters in blind hole 6, in elasticity
Under the action of slot 10, groove width is restored to original size, is fixed on plug 2 in connecting hole 5, and makes to block up under the action of spring 3
7 end face of lid and bolt end face, thus after ensure that assembly aboard, the planarization of aircraft surfaces；In use, by work
Tool is to just backward 4 internal pressure plug of twisting groove, to make twisting groove 4 expose, convenient for the installation or taking-up of bolt.
The protection scope of the utility model is not limited to technical solution disclosed in specific embodiment, all practical according to this
Novel technical spirit any modification, equivalent substitution, improvement and etc. to the above embodiments, each fall within the guarantor of the utility model
Protect range.
