Abstract
The utility model discloses a kind of entrance line special fastening structure, the left and right sides, bottom surface of intermediate plate has groove I upwards, the left and right sides of lower clamping piece end face has downward groove II, the middle intermediate plate end face left and right sides has downward groove III, the middle left and right sides, intermediate plate bottom surface has groove IV upwards, groove I is corresponding with the position of groove III and be combined as circle, groove II is corresponding with the position of groove IV and be combined as circle, bolt is from top to bottom successively through upper clip, middle intermediate plate and lower clamping piece, the position of only intermediate plate bottom surface on the lower, the bottom that nut is screwed in bolt.The utility model save assembly space, be beneficial between circuit dispel the heat, cost-saving, attractive in appearance, prevent from mutually wearing and tearing between circuit.
Description
Technical field
The utility model relates to a kind of fastening structure of electric wire.
Background technology
Present 0.4kV entrance line is in order to prevent friction damage between line, and between general line, spacing is very large, waste assembly space.In order to keep the distance between four wires (three-phase line adds a zero line), two of line needs to add cross-arm, every bar cross-arm all will add four insulators and fix circuit, altogether needs two cross-arms and eight insulators to fix, for the entrance line of several meters long, and uneconomical.In addition, because wire spacing is very large, in the place of overhead transmission line complexity, possibly cannot ensure the distance of entrance line and All other routes, cause difficulty to installation.Although Bundling conducting wire solves some problems, Bundling conducting wire cost is higher, and too concentrates heat radiation bad due to four wires, and the time is grown easy to be aging; Insulated hull is easily aging, and wire spacing is too little again, just easily causes short-circuit between conductors.
Summary of the invention
For solving the problems referred to above that existing fastening structure exists, the utility model patent provides a kind of entrance line special fastening structure, and its technical scheme taked is:
Comprise upper clip, lower clamping piece, middle intermediate plate, screw bolt and nut, the left and right sides, bottom surface of upper clip has groove upwards
, the left and right sides of lower clamping piece end face has downward groove
, the middle intermediate plate end face left and right sides has downward groove
, the left and right sides, middle intermediate plate bottom surface has groove upwards
, groove
and groove
position corresponding and be combined as circle, groove
and groove
position corresponding and be combined as circle, bolt from top to bottom successively through upper clip, middle intermediate plate and lower clamping piece, the position of only intermediate plate bottom surface on the lower, the bottom that nut is screwed in bolt.
Three intermediate plates of the present utility model are used for securing electric lines, entrance line two ends can not use cross-arm and insulator, wherein upper clip and middle intermediate plate, respectively between lower clamping piece and middle intermediate plate fix two lines, prevent the mutual winding between line and wearing and tearing mutually, greatly reduce the installing space of entrance line, line is made to gather within a very little scope, save space, turn increase attractive in appearance, screw bolt and nut is for clamping three intermediate plates, because the distance between screw bolt and nut is adjustable, this kind of fastening frame can clamp the wire of various diameter model in certain limit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the left and right sides, bottom surface of upper clip 1 has groove upwards
, the left and right sides of lower clamping piece 2 end face has downward groove
, the middle intermediate plate 3 end face left and right sides has downward groove
, the left and right sides, middle intermediate plate 3 bottom surface has groove upwards
, groove
and groove
position corresponding and be combined as circle, groove
and groove
position corresponding and be combined as circle, bolt 4 is from top to bottom successively through upper clip 1, middle intermediate plate 3 and lower clamping piece 2, and nut 5 is screwed in the bottom of bolt 4.The groove of upper clip 1
with the groove of middle intermediate plate 3
, lower clamping piece 2 groove
with the groove of middle intermediate plate 3
between respectively fix two lines, in order to anti-skidding, all bossed skid-proof point in each intermediate plate inside, makes its only intermediate plate 2 bottom surface on the lower, for clamping three intermediate plates by screw on nut 4.
