Specific embodiment
To clearly demonstrate design philosophy of the invention, below with reference to example, the present invention will be described.
In example as shown in Figs. 1-3, wedge strain resistance cable clamp of the invention, comprising: positioning sheath 1, sheath 2, upper clamp plate
3, lower clamp plate 4, connecting plate 6 and one group of anti-drop device 7；Wherein, the mounting plane of positioning sheath 1 and sheath 2 passes through 4 screws 5
Connection forms the wedge-shaped sheath for having wedged hole, and the rectangular area of wedged hole front-end cross-sectional view is greater than the rectangular surfaces in cross sectional rear end face
Product；Upper clamp plate 3 and lower clamp plate 4 are disposed through in the wedged hole, and upper clamp plate 3 is parallel with the corresponding surface of lower clamp plate 4, in upper clamp plate
3 upper surface and the lower surface of lower clamp plate 4 are bonded with two cleat planes of the wedged hole respectively, outside wedged hole front end
Side, upper clamp plate 3 and lower clamp plate 4 are bolted to connection to form cleat assembly.
Upper clamp plate 3 and lower clamp plate 4 respectively correspond on its contact surface is provided with arc groove, on upper clamp plate 3 and lower clamp plate 4
Corresponding arc groove forms the metallic channel 9 of clamping conducting wire 8；Being equipped on positioning sheath 1 prevents positioning sheath 1 and upper clamp plate 3
The anti-drop device 7 of disengaging is disengaged from the groove 3-1 with the anti-of the cooperation of anti-drop device 7 as shown in figure 4, being provided on upper clamp plate 3.It is anti-to be disengaged from the groove 3-1
Fixed connection end close to upper clamp plate 3 and lower clamp plate 4 opens up.When wedge strain resistance cable clamp clamps conducting wire 8, pass through anticreep
Device 7 and the anti-cooperation for being disengaged from the groove 3-1, prevent upper clamp plate 3 from skidding off along the cleat planes of wedged hole from the front end of wedged hole, simultaneously
Since cleat assembly is bolted into upper clamp plate 3 and lower clamp plate 4, cleat assembly can reliably press from both sides conducting wire 8
It holds, the pressure that a whole set of wedge clamp guarantees that cleat assembly clamps conducting wire 8 is met the requirements.
Preferably, the structure of upper clamp plate 3 and lower clamp plate 4 is identical, and identical mold pair can be used in processing in this way
Upper clamp plate 3 and lower clamp plate 4 are processed, and processing cost is saved, it is often more important that, it does not need deliberately to carry out folder during installation
The differentiation of plate 3 and lower clamp plate 4, in this way, just saving the set-up time of wedge strain resistance cable clamp.
Alternatively, the structure of upper clamp plate 3 and lower clamp plate 4 is only that hand of spiral of fixedly connected hole or fixedly connected hole etc. is thin
The processing of section is different, in this way in processing, equally there is above-mentioned processed edge.
As shown in figure 5, the first anti-drop device 7 of the invention is integrally formed structures, the upper end is holding screw, under
End is positioning pin, and wherein the diameter of positioning pin is less than the diameter of holding screw.Anti-drop device 7 can be by positioning sheath 1
Internal thread hole is simultaneously installed to anti-be disengaged from the groove in 3-1.Cleat assembly is prevented by anti-drop device 7 and the anti-cooperation for being disengaged from the groove anticreep slot 3-1
It is slipped from wedged hole.
As shown in fig. 6, anti-drop device 7 includes holding screw 7-1 and and tightening in another embodiment of the invention
The positioning pin 7-3 of screw 7-1 connection；Holding screw 7-3 has external screw thread, offer on positioning sheath 1 with outside holding screw 7-1
The internal thread hole being threadedly engaged；The diameter of positioning pin is less than the diameter of the internal thread hole, and positioning pin 7-3 can pass through positioning sheath
Internal thread hole on 1 is simultaneously installed to anti-be disengaged from the groove in 3-1.Positioning pin 7-3 press against it is anti-be disengaged from the groove in 3-1, block cleat assembly from
It is skidded off in wedge-shaped sheath.
Above-mentioned holding screw 7-1 can be fixedly connected with mode using threaded connection, clamping etc. with positioning pin 7-3.
As shown in fig. 7, anti-drop device 7 includes holding screw 7-1, spring 7-2 in the third embodiment of the invention
With positioning pin 7-3, between spring 7-2 connection holding screw 7-1 and positioning pin 7-3.When installing anti-drop device 7, pass through tightening
Screw 7-1 is fastenedly connected with internal thread hole on positioning sheath 1, is disengaged from the groove the top positioning pin 7-3 in 3-1 mounted in the anti-of upper clamp plate 3,
By the compression of spring 7-2, so as to be deep into the anti-position for being disengaged from the groove 3-1 constant by positioning pin 7-3, not by wedge-shaped sheath and clamping plate group
The influence of part change in location blocks cleat assembly and skids off from wedge-shaped sheath, meanwhile, it prevents positioning pin 7-3 and prevents being disengaged from the groove 3-1
Between occur stuck, improve the use reliability of wedge strain resistance cable clamp.
In above-mentioned anti-drop device 7, spring 7-2 can pass through welding, riveting etc. with holding screw 7-1 and positioning pin 7-3
Mode is fixedly connected, can also be by the grooved faces that connect in holding screw 7-1 and positioning pin 7-3 with screw, by spring 7-2
It is removably connected between holding screw 7-1 and positioning pin 7-3.
In addition, the outer surface of positioning sheath 1 is equipped with trunnion 1-1, set at sheath 2 and trunnion 1-1 corresponding outer surface position
There are trunnion 2-1, trunnion 1-1 and trunnion 2-1 radial symmetric, one end of two connecting plates 6 is mounted on trunnion 1-1 and trunnion 2-1,
The other end of two connecting plates 6 is connected by connection gold utensil with insulator.
It should be noted that some of which structure can have different selections other than the above-mentioned specific example provided.
Such as, 2 groups or more anti-drop devices 7 can be installed, specific setting needs line footpath and service condition according to conducting wire on positioning sheath 1
Etc. factors selected；The mounting plane of positioning sheath 1 and sheath 2 forms wedged hole by 4 with the connection of screwing 5, specifically
Screw number determination be according to the size of wedge strain resistance cable clamp determine；Etc., and these are all that those skilled in the art exist
Understanding can be made based on its basic skills on the basis of inventive concept, therefore no longer be enumerated herein.
Finally, it will be appreciated that the principle that embodiment of above is intended to be merely illustrative of the present and the example that uses
Property embodiment, however the present invention is not limited thereto.For those of ordinary skills, do not depart from it is of the invention
In the case where principle and essence, various changes and modifications can be made therein, these variations and modifications are also considered as protection model of the invention
It encloses.
