The cable fixture generally adopting now, is easy to cause stressed concentrating, operation with the anchor ear that round steel is madeCable outer layer. While making of plastics or steel plate, be easy to again because clamping force makes cable stressed not, as this masterpieceWhile being used in junction, be easy to cause junction electric elements, or the damage of other power equipment.

Summary of the invention

To be solved in the utility model is the stressed rapid wear in the each parts of existing open-close type cable fixture junctionBad, and the problem of cable dismounting inconvenience.

In order to address the above problem, the utility model provides a kind of open-close type cable fixture, and its feature existsIn, comprising the base being connected and fixed with cable built-in beam, base is provided with the circular arc matching with cable downsideGroove; One end of base is flexibly connected with one end of upper fixing element, and upper fixing element is provided with cable upside and matchesCircular arc jig arm; The other end of base and upper fixing element is connected and fixed by connector.

Preferably, fixed part is connected by rotating pin with one end that base is flexibly connected.

Preferably, one end of described rotating pin is circular protrusions structure, and the other end is provided with draw-in groove, in draw-in groove, establishesThere is back-up ring.

Be respectively equipped with two arc-shaped structures in the bottom of upper fixing element and the top of base, cable is passed by thisIn the circular port of two arc-shaped structure compositions; Hexagon-headed bolt (joining bullet pad, plain cushion) is passed to upper fixing elementIn the Long Circle hole being provided with, and be anchored on base and be provided with in screw, complete the fixing of cable.

Fixture and base are all made of cast steel material, rotating pin steel, have ensured the mechanism of whole deviceIntensity; It is larger that the bottom of upper fixing element and the top of base are respectively equipped with two arc surface surface areas, in order to avoid damageThe protection of cable outer layer and insulating barrier; The Long Circle hole that upper fixing element is provided with, when hexagon-headed bolt is through this holeTime, make hexagon-headed bolt can carry out appropriate adjusting, ensure to be subject to when fastening larger out-of-balance force.

The utility model structural strength is large, the lifting surface area of bearing's active force is large, is that one is easy to install and useCable fixture, there is principle novelty, simple in structure, strong adaptability, be suitable for batch production; Operation letterThe advantage single, easy to use, efficiency of construction is high.

Detailed description of the invention

For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.

Embodiment

As shown in Fig. 1-8, for a kind of open-close type cable fixture that the utility model provides, comprise base 5,Base 5 is provided with three screws 14, one of left end, and two of right-hand members, base 5 passes through through two of left and right spiral shellTwo bolts 26 in hole 14 are fixedly connected with cable built-in beam 7. Base 5 is provided with and cable 3 downside phasesThe circular groove 12 coordinating; Upper fixing element 2 is provided with the circular arc jig arm 9 matching with cable 3 upsides. The endThe left end of seat 5 is provided with installing hole 2 13, and the left end of upper fixing element 2 is provided with installing hole 1, at installing hole one10, in installing hole 13, insert rotating pin 1, make base 5 and upper fixing element 2 pass through rotating pin 1 activityConnect. As shown in Figure 7,8, one end of rotating pin 1 is circular protrusions structure 16, and the other end is provided with draw-in groove15, the one end that is provided with draw-in groove 15 is inserted in installing hole 1, installing hole 2 13, in draw-in groove 15, putA back-up ring 8. The right-hand member of upper fixing element 2 is opened a Long Circle hole 11, and connector 4 is inserted to Long Circle holeIn another screw 14 of the right-hand member of 11 rear inserted bases 5, base 5 is connected with the right-hand member of upper fixing element 2Fixing, connector 4 adopts bolt one.

Wherein, back-up ring 8 is standard component, carries out GB/T893.1-1986 standard; Bolt one, bolt 26 areStandard component, carries out GB5782-86 standard, when assembling, supporting corresponding bullet pad, plain cushion. Upper fixing element2 and base 5 all adopt cast steel material, rotating pin 1 adopts steel to make, and has ensured the mechanism of whole deviceIntensity; The top of the bottom of upper fixing element 2 and base 5 is respectively equipped with circular arc jig arm 9, circular groove 12,Both arc surface surface areas are larger, avoided the outer field protection of damage cable 3 and insulating barrier; On upper fixing element 2The Long Circle hole 11 being provided with, in the time that bolt 24 passes Long Circle hole 4, can carry out appropriate adjusting,Ensure when fastening to be subject to larger out-of-balance force, and can adapt to the cable 3 of different-diameter.

When assembling, first assemble this open-close type cable fixture, by the installing hole of upper fixing element 21 and the endThe installing hole two 13 of seat on 5 is corresponding, and passes these two holes with rotating pin 1, at rotating pin 1In draw-in groove 15, assemble back-up ring 8, ensure that upper fixing element 2 is around rotating pin 1 flexible rotating. Then, by bolt26 mix corresponding bullet pad, plain cushion, by the hole on cable built-in beam 7, and set spiral shell on precession base 5In hole 14, by cable fixture fixation.
