Description
Technical field
The present invention relates to a kind of bolt, bolt is tightened in especially a kind of one side for being used to close bonding pad, belongs to aircraft and sets
Count technical field.
Background technology
Largely using the connector such as bolt in Aircraft Production assembling, but the connector such as bolt is, it is necessary to certain installation
Space.Because bolt is installed using nut, the instruments such as spanner are often used when nut is installed, spanner is when in use to sky
Between require higher, general is difficult relatively to be used in the section of closing.Plate nut is the common bolt that can be tightened in one side,
For supporting plate by rivet interlacement in structure, this can add structural connection quantity, increase construction weight, and excessive perforate
Structural strength and fatigue behaviour can be reduced.And plate nut also has higher requirement to installation, if desired for enough planes and
Space mounting supporting plate, enough operating spaces are also required to when riveter is followed closely.
The content of the invention
Present invention aim to address problems of the prior art, there is provided one kind installation when to operating space require compared with
It is low and only need to tighten bolt with regard to the one side for being used to close bonding pad that can be tightened in unilateral operation.
To achieve the above object, the present invention adopts the following technical scheme that：Tighten spiral shell in a kind of one side for being used to close bonding pad
Bolt, bolt is tightened in the one side includes tow attachment, nut, core bar and bolt；The tow attachment uses strong magnetic material, uses
In nut and core bar are drawn to closing bonding pad bolt hole at；One end of the nut engages with one end of core bar, another
End is provided with the internal thread engaged with bolt；Through hole along its length is offered in the bolt；The core bar runs through spiral shell
The through hole of bolt.
Further, in addition to locking nut, screw thread is provided with inside and outside the locking nut, its internal thread and core bar
The other end engages, and external screw thread engages with the internal thread of bolt end.
Preferably, the hand of spiral of the locking nut and the hand of spiral of nut are opposite.
Preferably, the end set of the bolt has the through hole for accommodating locking nut.
Preferably, it is connected with drag rope on the tow attachment.
Preferably, the end of the core bar insertion bolt is yi word pattern.
The bolt employs tow attachment device, can be drawn to nut and core bar at the bolt hole of closing bonding pad.
During installation, by flat recess fixing bolt, rotation core bar drives nut rotation, and nut is tightened onto bolt.Core bar passes through lock
Tight nut is fixed on bolt, can increase the bearing capacity of bolt.Locking nut employs the screw thread reverse with nut, can be with
Play locking effect.
The present invention compared with prior art, has the following advantages that：
1st, only need to tighten bolt in one side operation can, operating space is not limited too much.
2nd, it is easy to produce, practicality is good, application easy to spread, has larger value.
Brief description of the drawings
Fig. 1 is explosive view of the embodiment of the present invention；
Fig. 2 is assembling schematic diagram of the embodiment of the present invention.
Embodiment
1-2 is further described to the present invention below in conjunction with the accompanying drawings：Bolt is tightened in a kind of one side for being used to close bonding pad,
Including：Core bar 1, nut 2, bolt 3, locking nut 4, tow attachment 5；Described one end of core bar 1 is round bar, and there is screw thread termination, separately
One end is six prisms, and there is baffle plate termination, and it is in " one " font that threaded one end, which is provided with breach,；Described one end of nut 2 be provided with
The hexagonal hole of the prism end of core bar six matching, the other end are provided with the internal thread that can be connected with bolt 3；The bolt 3
Centre, which offers, can hold the circular hole that core bar 1 passes through；Screw thread is provided with inside and outside the locking nut 4, it is anti-with the screw thread of nut 2
To its internal thread engages with the end of thread of core bar, and external screw thread engages with the internal thread of bolt end, and the end away from core bar opens up
It is jagged to be used to tighten locking nut；Described one end of tow attachment 5 has screw thread to be connected with core bar 1, and the other end is connected with pull rope
Rope, tow attachment are strong magnetic material.
First tow attachment 5 is put into the mounting hole of bolt during installation, can be with because tow attachment 5 is strong magnetic material
Closed interval is stretched into iron staff to take out tow attachment 5, then core bar 1 is connected on tow attachment 5 through nut 2, Ran Houyong
Drag rope pulls out core bar 1 out of bolt mounting holes, and now nut 2 is placed exactly in bolt installation site；During installation bolt, take
Lower tow attachment 5, bolt 3 is passed through into core bar 1, fixed bolt by the bolt flat recess of 3, core bar 1 is rotated, due to core bar
1 is connected together with nut 2 by hexagonal hole, and core bar 1 can drive nut 2 to rotate when rotating, therefore can be so that nut is tightened
Onto bolt 3；After nut 2 is tightened, locking nut 4 is installed on bolt 3, the one end of locking nut 4 is jagged to be can be used for twisting
Tightly.Due to there is screw thread inside and outside locking nut 4, therefore core bar 1 and bolt 3 can be fixed together, now core bar 1 can be with
The common stress of bolt, improve the bearing capacity of bolt.Locking nut 4 is with the hand of spiral of nut 2 on the contrary, can be played to nut 2
Locking effect.
Above-described embodiment is only the preferred embodiment of the present invention, is not construed as limiting the invention, core bar and nut
Snap fit be not restricted to the snap fits of six prisms and hexagonal hole in embodiment, other are such as：Triangular prism with
Triangle perforate, quadrangular and tetragonal perforate etc. can also realize that core bar drives nut rotation, those of ordinary skill in the art
The amplification or change done on the basis of the present invention, within the scope of the present invention.
