Abstract
The utility model discloses a kind of enhanced railway contact line fixing bolt of connecting bolt technical field, including hex bolts, the inner chamber of the hex bolts is provided with screwed hole, screw is bolted with the screwed hole, the inner cavity top of the screwed hole is provided with the upright opening leaned with screw head, the outer wall of the hex bolts is from top to bottom connected with hex nut in turn, stop scored card and briquetting, hex bolts is inserted on railway contact line dropper line, by briquetting, stop scored card, hex nut is connected in turn on hex bolts, briquetting is set to be in contact with railway contact line dropper line fixation by hex nut, Folding card is folded and is connected with hex nut, then by screw-driving, when upright opening is leaned at the top of screw, can be by hex bolts slightly spreading, play fixed locked effect.
Description
Technical field
Connecting bolt technical field is the utility model is related to, specially a kind of enhanced railway contact line fixing bolt.
Background technology
Bolt：Machine components, the cylindrical threaded fastener of adapted nut.External screw thread (is carried by head and screw rod
Cylinder) a kind of fastener dimerous, need to coordinate with nut, for be fastenedly connected two carry through hole parts.
This type of attachment claims bolt connection.It as nut is screwed off from bolt, can separate the two parts again, therefore bolt connection
It is to belong to be detachably connected.Railway contact line is used for fastening railway contact net with adjustment fixing bolt, and the railway that tradition uses connects
Net-fault is mostly simple in construction with fixing bolt, and function is single, and rigidity is poor, and tightness is poor, and nut easily loosens, therefore, I
Propose a kind of enhanced railway contact line fixing bolt.
Utility model content
The purpose of this utility model is to provide a kind of enhanced railway contact line fixing bolt, to solve above-mentioned background
The railway contact line that the tradition proposed in technology uses is mostly simple in construction with fixing bolt, and function is single, and rigidity is poor, fastening
The problem of property is poor, and nut easily loosens.
To achieve the above object, the utility model provides following technical scheme：A kind of enhanced railway contact line is fixed
Bolt, including hex bolts, the inner chamber of the hex bolts are provided with screwed hole, screw, the spiral shell are bolted with the screwed hole
The inner cavity top of pit is provided with the upright opening leaned with screw head, and the outer wall of the hex bolts is from top to bottom connected with turn
Hex nut, stop scored card and briquetting.
Preferably, the stop scored card includes pad, and the outer wall of the pad is uniformly provided with Folding card.
Preferably, inner chamber of the screwed hole longitudinally through hex bolts.
Compared with prior art, the beneficial effects of the utility model are：Hex bolts is inserted on railway contact line, will be pressed
Block, stop scored card, hex nut are connected in turn on hex bolts, make briquetting and railway contact line dropper by hex nut
Line is in contact fixation, and Folding card is folded and is connected with hex nut, and then by screw-driving, upright opening is leaned at the top of screw
When, hex bolts slightly spreading can be played fixed locked effect, the utility model is rational in infrastructure, easy to use, effectively
Solve that the railway contact line that uses of tradition is mostly simple in construction with fixing bolt, and function is single, rigidity is poor, tightness compared with
Difference, the problem of nut easily loosens.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model stop scored card structural representation.
In figure：1 hex bolts, 2 screwed holes, 3 upright openings, 4 screws, 5 hex nuts, 6 stop scored cards, 61 pads, 62
Folding card, 7 briquettings.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of enhanced railway contact line fixing bolt technical scheme：It is a kind of
Enhanced railway contact line fixing bolt, including hex bolts 1, the inner chamber of the hex bolts 1 is provided with screwed hole 2, described
It is bolted with screw 4 in screwed hole 2, the inner cavity top of the screwed hole 2 is provided with the upright opening 3 leaned with the top of screw 4, and described six
The outer wall of corner bolt 1 is from top to bottom connected with hex nut 5, stop scored card 6 and briquetting 7 in turn.
Wherein, the stop scored card 6 includes pad 61, and the outer wall of the pad 61 is uniformly provided with Folding card 62, institute
State inner chamber of the screwed hole 2 longitudinally through hex bolts 1.
Operation principle：During use：Hex bolts 1 is inserted on railway contact line, by briquetting 7, stop scored card 6, hexagonal
Nut 5 is connected in turn on hex bolts 1, briquetting 7 is in contact with railway contact line dropper line fixation by hex nut 5,
Folding card 62 is folded and is connected with hex nut 5, then tightens screw 4, can be with when the top of screw 4 leans upright opening 3
By the slightly spreading of hex bolts 1, fixed locked effect is played, the utility model is rational in infrastructure, easy to use, efficiently solves
The railway contact line that tradition uses is mostly simple in construction with fixing bolt, and function is single, and rigidity is poor, and tightness is poor, nut
The problem of easily loosening.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
