Specific embodiment
Referring to Fig.1, a kind of transformation cabinet wiring hole sealing structure proposed by the present invention, comprising: coaming plate 1, the first bend pipe 2,
Second bend pipe 3, the first core bar 4 and the second core bar 5.
First bend pipe 2 and the second bend pipe 3 are mounted on coaming plate 1 by spring 6 respectively and are located at 1 inner circumferential of coaming plate.First core
The first end of the first bend pipe 2 and the first end of the second bend pipe 3 are inserted into the both ends of bar 4 respectively, and the both ends of the second core bar 5 are inserted into respectively
The second end of the second end of first bend pipe 2 and the second bend pipe 3.First bend pipe 2, the first core bar 4, the second bend pipe 3 and the second core bar 5
It is in turn connected to form closed annular structure.First core bar 4 and the second core bar 5 are flexible joining part, to facilitate the first bend pipe 2 and
Two bend pipes 3 are opposite or back movement.
First bend pipe 2 and the second bend pipe 3 move toward one another or to unlucky in the plane as spring 6 stretches in coaming plate 1
It is dynamic, so that the inner ring size of closed annular structure is adjusted, will pass through the cable of the fixed different line footpaths of closed annular structure.
Specifically, when installing cable using the wiring hole sealing structure that present embodiment provides cable being passed through close first
Transformation cabinet is inserted by the threading hole on transformation cabinet again after closing ring structure, and adjusts length of the cable in transformation cabinet;So
Coaming plate 1 being resisted against on transformation cabinet to afterwards and guaranteed, the threading hole of closed annular structure and transformation cabinet is coaxially disposed;Coaming plate 1 is led to again
The mode for crossing screw or welding or viscose is fixed on transformation cabinet.Alternatively, when concrete application, it can also be fixed in advance by the coaming plate 1
On transformation cabinet and guarantee that the threading hole of closed annular structure and transformation cabinet is coaxially disposed, cable is then passed through into closed annular knot
Transformation cabinet is inserted by the threading hole on transformation cabinet again after structure.
After installing cable using the wiring hole sealing structure, the first bend pipe 2 and the second bend pipe 3 are buckled under the effect of spring 6
Stringing cable prevents cable from excessively reversing and causes to damage to which cable be fixed;Meanwhile first bend pipe 2, the first core bar 4,
Threading hole on two bend pipes 3 and the second core bar 5 covering transformation cabinet, ensure that the sealing performance of threading hole after cable insertion, avoids powder
The foreign matters such as dust-shower snow enter the risk of transformation cabinet.
And in present embodiment, with the first bend pipe 2 and the second bend pipe 3 is opposite or back movement, the first bend pipe 2, the
The closed annular structure that one core bar 4, the second bend pipe 3 and the second core bar 5 are in turn connected to form is approximately round always or oval
Shape facilitates cable and is matched by the Light deformation of sheath with the inner ring of closed annular structure, improves the rigorous of threading hole sealing,
It in turn avoids leading to cable excessive deformation in closed annular structure fastening process.
In present embodiment, each spring 6 is equipped with a corresponding connecting rod 7, and spring 6 is set in corresponding connection
On bar 7, and 6 one end of spring connects coaming plate 1, and 6 other end of spring connects the first bend pipe 2 or the second bend pipe 3.7 one end of connecting rod
It connects the first bend pipe 2 or the second bend pipe 3, the other end is slidably mounted on coaming plate 1.That is the first bend pipe 2 and the second bend pipe 3 are logical
It crosses connecting rod 7 to be slidably mounted on coaming plate 1, and is arranged with spring 6 in each connecting rod 7.In this way, the setting of connecting rod 7,
The glide direction of the first bend pipe 2 and the second bend pipe 3 is limited, thus ensure that the reliability of wiring hole sealing structure work,
It avoids spring 6 from deforming, is conducive to the service life for improving the wiring hole sealing structure.Specifically, in present embodiment, coaming plate 1
Each connecting rod 7 of upper correspondence is equipped with a groove, and connecting rod 7 is inserted into corresponding groove and is slidably connected with coaming plate 1, that is, connects
Extension bar 7 is connect with groove inner wall smooth surface.
In present embodiment, coaming plate 1 is ring structure, and the first bend pipe 2 and the second bend pipe 3 are articulated and connected with connecting rod 7.
To facilitate connecting rod 7 with the angle of the corresponding groove of the movement adjustment insertion of the first bend pipe 2 and the second bend pipe 3.
When it is implemented, coaming plate 1 can also be used as rectangular configuration.At this point, the first bend pipe 2 and the second bend pipe 3 with connection
Bar 7 is fixedly connected, and all connecting rods 7 are mutually parallel.
In further embodiment of the present invention, the periphery of the first bend pipe 2 and the second bend pipe 3 coats rubber sleeve 8, to keep away
Exempt to scratch cable during plug wire.Similarly, the first core bar 4 and the second core bar 5 are all made of rubber bodies.
Transformation cabinet provided by the invention wiring hole sealing structure, further includes bottom plate 9, and bottom plate 9 is fixedly connected with ground with coaming plate 1
It is mounted in the plane for being parallel to coaming plate 1, the first bend pipe 2 and the second bend pipe 3 are slidably mounted on bottom plate 9.Bottom plate 9 is equipped with
It is corresponding with the closed annular structure that the first bend pipe 2, the first core bar 4, the second bend pipe 3 and the second core bar 5 are in turn connected to form logical
Hole 10.In 3 motion process of first bend pipe 2 and the second bend pipe, 10 wall of through-hole is coated on closed annular structure inner ring periphery always.
In this way, the setting of bottom plate 9, the movement for the first bend pipe 2 and the second bend pipe 3 provides carrier, further ensures
The reliability of first bend pipe 2 and the movement of the second bend pipe 3.
Specifically, the transformation cabinet wiring hole sealing structure that present embodiment provides further includes sealing cover, set on sealing cover
There is a via hole, in threading process, cable first passes through sealing cover, then sequentially passes through annular closing structure again and through-hole is inserted into and wears
String holes.It threads in completing, then sealing cover is located at 1 periphery of coaming plate, to be protected to spring 6.
The above, preferable specific embodiment only of the present invention, but protection scope of the present invention not office
Be limited to this, anyone skilled in the art in the technical scope disclosed by the present invention, technology according to the present invention
Scheme and its inventive concept are subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
