Specific embodiment
Referring to Fig.1, a kind of switchgear cable perforator proposed by the present invention, comprising: pedestal and card line pipe.
The method that pedestal is circumferentially extended outward to form in the plane perpendicular to axis by straight pipe 11 and 11 one end of straight pipe
Blue face 12 forms.
Card line pipe is made of tube body 21, the first card line plate 22 and the second card line plate 23.Straight pipe 11 is equipped with external screw thread, pipe
Body 21 is equipped with internal screw thread, and tube body 21 is set in 11 periphery of straight pipe and along 11 axis direction threaded rotational movement of straight pipe.
The length of straight pipe 11 is greater than 21 length of tube body.That is, tube body 21 is opposite by screw thread rotation in the axial direction with straight pipe 11
Movement, so as to adjust the depth that straight pipe 11 is inserted into tube body 21 by rotation straight pipe 11 or tube body 21.
First card line plate 22 and the second card line plate 23 be hingedly mounted on tube body 21 and be located at 11 periphery of straight pipe, first
Card line plate 22 and the second card line plate 23 form the conical pipeline structure being coaxially disposed with tube body 21.
The two sides of first card line plate 22 and the second card line plate 23 pass through spring 24 and connect.Spring 24 under natural conditions, is bored
The shape pipeline configuration tip area of a circle is less than 11 circular section of straight pipe.
Specifically, under natural conditions, the big nose circle of conical pipeline structure is coated on outside tube body 21 spring 24 in present embodiment
Week is connect with tube body 21 by end face.In this way, to lead directly to by rotary feedthrough pipe 11 after straight pipe 11 is inserted into tube body 21
Pipe 11 stretches out tube body 21 and is simultaneously pressed further by the first card line plate 22 and the second card line plate 23, can make the first card line plate 22 and the
Two card line plates 23 strut；With close, the first card line plate 22 and the second card of straight pipe 11 and conical pipeline structure distance between two tips
Relative distance between line plate 23 is bigger；To which first can be adjusted by adjusting the rotation depth of straight pipe 11 and tube body 21
The cable rugosity that card line plate 22 and the second card line plate 23 can clamp, to meet the clamping requirement of the cable of plurality of specifications.
The switchgear cable perforator that present embodiment provides further includes extension tube 3, the first card line plate 22 and the second card
Line plate 23 is installed in inside extension tube 3, and extension tube 3 is fixedly connected with tube body 21.In this way, pass through the setting of extension tube 3, it is right
Limitation is protected and moved to first card line plate 22 and the second card line plate 23, advantageously ensures that the first card line plate 22 and the second card line
The stabilization that plate 23 works；Meanwhile the extending direction for the cable for passing through card line pipe can also be limited by extension tube 3, it can keep away
Exempt to be caused to damage by the cable overbending deformation that the first card line plate 22 and the second card line plate 23 clamp.In present embodiment, prolong
Long tube 3, tube body 21 and conical pipeline structure are coaxially disposed.
In further embodiment of the present invention, 11 inner circumferential of straight pipe is equipped with sealing ring 4 close to one end of flange face.In this way,
The gap between straight pipe 11 and cable is blocked by sealing ring 4, is conducive to that dust is avoided to enter perforator.Specifically, sealing
Circle 4 uses rubber ring.
In present embodiment, 11 inner circumferential of straight pipe is equipped with annular groove, and sealing ring 4 is installed in a ring groove.In this way, annular groove
Setting, sealing ring 4 can be limited, guarantee sealing ring 4 installation stablize, to guarantee its working effect.
In further embodiment of the present invention, the tip of the first card line plate 22 and the second card line plate 23 is rounded structure,
To avoid scuffing cable.
In further embodiment of the present invention, flange face 12 is equipped with location hole, and pedestal passes through the screw across location hole
It is mounted on switchgear.In this way, the setting of flange face 12, provides convenience for the installation of the perforator.
