Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described, aobviousSo, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative workThe every other embodiment obtaining under prerequisite, belongs to the scope that the utility model is protected.
Fig. 1 to Fig. 9 shows the embodiment of a kind of wedge strain resistance cable clamp that the utility model provides.
As can be seen from Figure 1, this wedge strain resistance cable clamp comprises housing 2 and link plate assembly. Housing 2Inside be provided with wedge cavities. " wedge cavities " is interpreted as cavity and has the characteristic of wedge structure, chamber hereinBody true form can be cone shape according to actual conditions or cross section is trapezoidal square shape.
Housing 2 is pyramidal structure, the big opening end of the corresponding wedge cavities of stub end of housing 2; Housing 2Microcephaly holds the osculum end of corresponding wedge cavities. This housing 2 is at little head end, i.e. the osculum end of corresponding wedge cavities,Be provided with incoming line 3, cable enters this wedge strain resistance cable clamp by this incoming line 3. This housing 2 is at major partEnd, i.e. the big opening end of corresponding wedge cavities, is provided with line outlet 9, and cable stretches out this wedge by this line outlet 9Shape strain clamp. In the technical program, housing 2 can be structure as a whole, and also can be multiple housing parts 2Be spliced.
Please refer to Fig. 2 and Fig. 3, in this wedge cavities, be provided with the sandwich assembly 7 that can slide along this wedge cavities.This sandwich assembly 7 comprises at least two identical sandwiches 71. Sandwich 71 amalgamations of sandwich assembly 7 formThe clamp groove 8 of accommodating cable. These clamp groove 8 openings align with incoming line 3 and the line outlet 9 of housing 2.At sandwich assembly 7, along in wedge cavities sliding process, clamp groove 8 expands or shrinks, thus realize rightBe positioned over unclamping or locking of these clamp groove 8 inner cable.
It should be noted that, herein, sandwich assembly 7 is locked direction and is referred to that sandwich assembly 7 is in wedge cavitiesThe direction of motion that clamp groove 8 is shunk, specifically refers in the present embodiment that sandwich assembly 7 is near incoming line 3The direction of motion; In like manner, sandwich assembly 7 unclamps direction and refers to that sandwich assembly 7 makes clamp in wedge cavitiesThe direction of motion that groove 8 expands, specifically refers to the motion of sandwich assembly 7 away from incoming line 3 in the present embodimentDirection.
This wedge strain resistance cable clamp also comprises elastic component, and this elastic component acts on sandwich assembly 7 and promotes shouldSandwich assembly 7 slides to lock cable along wedge cavities. Promoting sandwich assembly 7 herein slides along wedge cavitiesThe elastic force direction that acts on sandwich assembly 7 taking locking cable thrum part is as sandwich assembly 7 locking sidesTo (with reference to above), in the present embodiment, elastic component promotes sandwich assembly 7 towards incoming line 3 direction fortuneMoving. Elastic component acts on active force on sandwich assembly 7 has increased the coupling mechanism force of sandwich assembly 7 to cable,Thereby improve the reliability of this wedge strain resistance cable clamp. And due to the increase of coupling mechanism force, save thisThe process that wedge strain resistance cable clamp needs instrument to carry out pre-locking before installing, has improved the convenience of installing.
This housing 2 is provided with baffle plate 5 away from one end of incoming line 3, and in the present embodiment, elastic component is for establishingBe placed in the spring 6 between baffle plate 5 and sandwich assembly 7. As can be seen from Figure 9, baffle plate 5 is removableUnload structure, be connected with housing 2 by screw element, baffle plate 5 offers line outlet 9. Apparently,Housing 2 and baffle plate 5 also can be designed to integrative-structure.
As can be seen from Figure 3, in the present embodiment, sandwich assembly 7 comprises three identical sandwiches 71,Circumferencial direction in wedge cavities evenly arranges, and adjacent two sandwiches 71 are with respect to clamp groove 8 axisAngle be 120 degree. And sandwich 71 has the extension of setting radian at wedge cavities circumferencial direction. ThreeIndividual that the coupling mechanism force that sandwich 71 is subject to cable is evenly set is more even, thereby makes this wedge tension resisting lineThe Performance And Reliability of folder locking is higher.
Please refer to Fig. 4, Fig. 5 and Fig. 6, sandwich 71 comprise towards the medial surface of clamp groove 8 and towardsThe lateral surface of wedge cavities. Preferably, sandwich 71 medial surfaces be provided with top towards with described sandwich groupPart 7 is locked the pawl 711 of opposite direction. The setting of pawl 711 can effectively improve sandwich 71 to cableFrictional force, improve clamp effect. Further preferred, sandwich 71 lateral surfaces are provided with province's hopper 712,Can effectively alleviate sandwich 71 weight.
This wedge strain resistance cable clamp also comprises link plate assembly, and link plate assembly comprises two link plates that are oppositely arranged1. Two link plate 1 one end interfix, for this wedge strain resistance cable clamp is connected to the insulation on pylonString or be connected to other structures. The other end is connected with housing 2. On housing 2, be provided with mount pad 4,The corresponding each link plate 1 of this mount pad 4 offers installing hole, and installing hole is that screwed hole and axis direction hang downDirectly in housing 2 length bearing of trends. Link plate 1 is arranged at the screw element in this installing hole rotationally.
From Fig. 7 and Fig. 8, can find out, link plate 1, for the platy structure of bending, is established on its lateral surfaceBe equipped with the stiffener 11 that increases self intensity.
The using method of this wedge strain resistance cable clamp:
Cable and damper ends is aimed to the firmly pushing of clamp hole, spring 6 is compressed, thereby make line hole become large,Cable is taken advantage of a situation and is inserted in line-entering hole, and in the time that cable puts in place, cable is locked in spring 6 resiliences, completes lineThe installation of cable and wedge strain resistance cable clamp.
Obviously, above-described embodiment is only for example is clearly described, and not to the side of enforcementThe restriction of formula. For those of ordinary skill in the field, also can on the basis of the above descriptionTo make other changes in different forms. Here without also giving all embodimentsWith exhaustive. And the apparent variation of being extended out thus or variation are still created in the utility modelProtection domain among.
