Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The first embodiment is as follows:

fig. 1 is the utility model discloses cable hole polisher's embodiment one, cable hole polisher, including solid fixed cylinder 1, a propelling movement section of thick bamboo 2, polishing dish 3 and actuating lever 4, the one end of propelling movement section of thick bamboo 2 stretches into solid fixed cylinder 1 in, and the propelling movement section of thick bamboo 2 relatively fixed cylinder 1 along axial displacement, 4 one ends of actuating lever link to each other with polishing dish 3, and the other end of actuating lever 4 pushes up in propelling movement section of thick bamboo 2 after passing solid fixed cylinder 1, it has external screw thread 5 to open on the middle part outer wall of actuating lever 4, be equipped with in the solid fixed cylinder 1 with external screw thread 5 complex internal thread hole 6, move along the axis through propelling movement section of thick bamboo 2 relatively fixed cylinder 1 and drive polishing dish 3 rotary polishing.

Through the axial displacement of the relative solid fixed cylinder 1 of a propelling movement section of thick bamboo 2, promote the forward motion of actuating lever 4, simultaneously because the external screw thread 5 at 4 middle parts of actuating lever and the cooperation in internal thread hole 6 for actuating lever 4 takes place rotatoryly when moving forward, polishes the operation by the polishing dish 3 of 4 heads of actuating lever in to the cable hole, and this device simple structure, light in weight is fit for the operation personnel to carry and goes out, alleviates the operation personnel burden.

In order to provide sufficient revolving force, internal thread hole 6 can set up on fixed plate 7 in solid fixed cylinder 1, when promoting actuating lever 4 to move along the axis like this, internal thread hole 6 and the external screw thread 5 interact on the actuating lever 4, just enable actuating lever 4 to rotate, when promoting, the other end top of general actuating lever 4 is on the interior terminal surface of pushing a section of thick bamboo 2, reduce the driving lever 4 and the frictional force between a section of thick bamboo 2 in order to reduce the wearing and tearing to pushing a section of thick bamboo 2 interior terminal surface simultaneously, the other end of actuating lever 4 can set up to the hemisphere, of course also can be for ellipse or other arcwall faces.

As shown in fig. 3, in order to ensure that the pushing cylinder 2 can move along the axis relative to the fixed cylinder 1, a guide groove 8 is formed in the inner wall of the fixed cylinder 1, the guide groove 8 can be a dovetail groove or a rectangular groove, the guide groove 8 is parallel to the axis of the fixed cylinder 1, and meanwhile, a guide strip is arranged on the pushing cylinder 2 to be matched with the guide groove 8, so that the pushing cylinder 2 is prevented from rotating relative to the fixed cylinder 1 when the pushing cylinder 2 is pushed, and the guide strip is arranged on the outer side wall of the pushing cylinder 2 and is matched with the guide groove 8 of the fixed cylinder 1.

As shown in fig. 4, four placing cavities 9 are formed in the top end of the polishing disc 3, a polishing disc 10 is arranged in each placing cavity 9, the polishing discs 10 are hinged to the placing cavities 9, the placing cavities 9 are communicated with the outside, when the polishing disc 3 rotates, one end of each polishing disc 10 can be thrown out of the placing cavity 9 to polish cable holes, in order to withdraw the polishing discs 10 when the polishing disc 3 stops rotating, a torsion spring 11 is arranged between each polishing disc 10 and the corresponding side wall of the placing cavity 9, once the polishing disc 3 stops rotating, the polishing discs 10 are withdrawn into the placing cavities 9 under the action of the elastic force of the torsion spring 11, and therefore when the polishing discs 10 are not used, the polishing discs 10 are located in the placing cavities 9 to be protected, and the polishing discs 10 are prevented from being damaged.

During the use, the fixed section of thick bamboo 1 is held to operating personnel one hand, the propelling movement section of thick bamboo 2 is held to the other hand, stretch into the cable hole with polishing dish 3, promote propelling movement section of thick bamboo 2, it removes to the cable hole internal direction along fixed section of thick bamboo 1 axis to promote a section of thick bamboo 2, because the removal of propelling movement section of thick bamboo 2, it also removes to promote actuating lever 4, because actuating lever 4 and the 6 threaded connection in the internal thread hole of fixed section of thick bamboo 1, can take place rotatoryly when actuating lever 4 removes along the axis, thereby drive polishing dish 3 and rotate, the centrifugal force of the rotatory production of polishing dish 3 throws away the polishing piece 10 on polishing dish 3 top and forms the polishing face, polishing piece 10 polishes the inner wall in cable hole. After the polishing disc 3 stops rotating, the polishing sheet 10 will be retracted into the placing cavity 9 by the elastic force of the torsion spring 11, and the polishing sheet 10 is prevented from being damaged during transportation. Since the diameter of the polishing pad 10 after being thrown out is variable, the polishing pad 3 of the present embodiment can accommodate cable holes of various diameters.

Example two:

as shown in fig. 2, the difference from the first embodiment is that the polishing disk 3 has a different structure, the polishing disk 3 of the present embodiment has a truncated cone shape, a larger end surface of the polishing disk 3 is fixedly connected to one end of the driving rod 4, and a side surface of the polishing disk 3 is a polishing surface.

During the use, stretch into the cable hole with the front end of polishing dish 3, owing to be the polishing dish 3 of round platform shape, so the front end of general polishing dish 3 is littleer a bit than the internal diameter in cable hole, promotes to push a section of thick bamboo 2 and moves along 1 axis of fixed section of thick bamboo, and when actuating lever 4 drove the rotation of polishing dish 3, polishing dish 3 stretched into in the cable hole, polished the cable hole through the side of polishing dish 3. The best maximum diameter of polishing dish 3 of this embodiment equals with the internal diameter in cable hole, can carry out disposable polishing, improves polishing efficiency, can also carry out the plastic to the cable hole simultaneously.

The above description is only for the specific embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
