The utility model finishes the action of locking and adjusting the hanging-string wire and clamping the contact conductive-wire by one component, and has the advantages of novel design, reasonable structure, low cost and convenient length adjustment.

Description

Contact wire corrosion-resistant steel dropper clip

Technical field:

The utility model is that clip is adjusted in the locking that connects electrification contact network dropper line and contact wire.

Background technology:

At present, it is two-part that clip is adjusted in the dropper line of electrification contact network and the locking of contact wire, the upper end of dropper line has a non-conductive to adjust snap close and load line sliding block joint, the lower end has dropper folder and contact wire to clamp, the length adjustment of dropper line leans on the adjustment snap close of dropper line upper end to regulate and locking, so install and keep in repair, adjust all inconvenient.

Summary of the invention:

The purpose of this utility model is a kind of installation of design and keeps in repair, adjusts all contact wire corrosion-resistant steel dropper clip very easily.

The technical solution of the utility model is finished as follows, it comprises one by locked body, clamping piece and bolt, the adjustment snap close that nut is formed, it is characterized in that: adjust the wedge lock sheet that also has a belt length circular hole between the wedge flute profile locked body of snap close and the clamping piece and be enclosed within on the bolt and compress with nut, slightly arc is recessed for the limit wall of wedge lock sheet, the base of locked body is provided with an arc tingle after an end prolongs, be provided with the axis pin base of symmetry in the both sides of prolongation, in the pin shaft hole on axis pin base top bearing pin is installed, also have upper strata one end of a double-deck clamp holder to embrace bearing pin, cooresponding lower floor end is that the outstanding arc of a semicircle contacts with the arc top of the movable intermediate plate of arc of bearing pin below, upwards there is certain bending at the clamp holder middle part, the rear end bending of movable intermediate plate withstands on the tingle, the fulcrum top of movable intermediate plate contacts with the backarc of double-deck clamp holder is prominent, and the front end of movable intermediate plate and tingle is the arc folder mouth that can clamp in contact wire two notches.The utility model will be locked with two kinds of functions adjusting the dropper line and clamp contact wire and be finished by a combiner, so have modern design, rational in infrastructure, cost is low, install and maintenance, adjust all advantage very easily.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the top plan view of locked body when not adorning bolt and nut.Among the figure, 1. wedge flute profile locked body, 2. axis pin base, 3. tingle, 4. movable intermediate plate, 5. bearing pin, 6. double-deck clamp holder, 7. spring cotter, 8. nut, 9. bolt, 10. wedge lock sheet, 11. clamping pieces.

The specific embodiment:

The utility model is that two kinds of functions designs adjusting locking dropper line and clamping contact wire are finished on a device, it comprises an adjustment snap close of being made up of wedge flute profile locked body 1, clamping piece 11 and bolt 9, nut 8, the wedge lock sheet 10 of a belt length circular hole is enclosed within on the bolt 9 and compresses with nut 8 in addition between the locked body 1 of adjusting snap close and clamping piece 11, slightly arc is recessed in the middle of the wedge shape limit wall of wedge lock sheet 10, result of use the best.Base one end of locked body 1 prolongs into an arc tingle 3, be provided with the axis pin base 2 of symmetry in the both sides of base prolongation, bearing pin 5 is installed in the pin shaft hole on axis pin base top, be with a double-deck clamp holder 6 on the bearing pin, upper strata one end of double-deck clamp holder is embraced bearing pin 5, cooresponding lower floor end is that the outstanding arc of a semicircle contacts with the arc top of the movable intermediate plate 4 of arc of bearing pin below, and upwards there is certain bending at the clamp holder middle part.Crooked about 90 degree in the rear end of movable intermediate plate withstand on the tingle, dash forward with the backarc of double-deck clamp holder and contact in the fulcrum top of movable intermediate plate, and the front end of movable intermediate plate and tingle is can insert in contact wire two notches and the arc that clamps folder mouth.The function of adjustment of the present utility model and locking dropper line is to fix by the dropper line extruding that the wedge-shaped edge between its wedge flute profile clip body and the wedge lock sheet will be passed through, owing on the stay slotted hole is arranged, so the dropper line draws under tension more, pressure just tight more.The length adjustment of dropper line is also very convenient.Bolt adopts cup head square neck bolt, operates easier.Realizing clamping in the function of contact wire, main by double-deck clamp holder, after it adopts two 1.5 millimeters stainless steel sheet drawings, the spot welding that is superimposed is up and down reinforced, slice embrace bearing pin on it, the outstanding arc of the semicircle of following sheet front end contact with the live splint middle part, and the rear fulcrum by live splint presss from both sides the arc folder mouth of front end by elasticity will contact the wire casing clamping.Because the eccentric semi arch effect on the following sheet is arranged, and it is firm to hold, and can prevent resilience again.In order more effectively to prevent double-deck clamp holder resilience, be provided with cotter-pin hold at the rear portion of double-deck clamp holder and the tingle corresponding position of locked body prolongation, can mix spring cotter 7 in case of necessity and fix.This clip is finished two kinds of functions with parts, it is rational in infrastructure, and is easy to use.
