1. Field of the invention
The present invention relates to a pulley assembly for wire combination, and more particularly, to a pulley assembly for wire combination which can easily connect a cable wire with a pulley.
2. Description of Related Art
Generally, a pulley assembly for wire combination has been used for various fields, but has been mainly used for a door glass field.
The door glass is disposed between a door outer panel and a door inner panel in a vertically reciprocating manner.
A carrier plate is fixed to a lower end of the door glass and is connected with a door glass regulator motor via a wire rope.
When a switch disposed in the inside of a car is operated, an opening and closing operation of the door glass is performed by vertically moving the carrier plate along a regulator channel by pulling a wire rope while a regulator drum is rotated and a change in an angle of the wire rope is performed by the regulator pulley.
As illustrated in
As a result, when a wire W is assembled to the locking groove 12 of the pulley 10 and then, rotatably inserted, the wire W is combined with the guide groove 11.
However, the pulley assembly for wire combination according to the related art has a disadvantage in that it is difficult for the wire W to jump over the locking groove 12 of the pulley 10 and advance the guide groove 11 at the time of rotating the pulley 10, thereby reducing adhesion. Further, when the wire W is combined with the pulley 10, the wire W is locked to the locking groove 12 to increase the risk of damage.
The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present invention are directed to providing a pulley assembly for wire combination so as to solve the above problems. In particular, one subject to be achieved by the present invention is to easily combine a cable wire with a pulley.
In an aspect of the present invention, a pulley assembly for combining of a wire, may include a groove member having a first guide groove helically threaded in an outer circumferential surface thereof and having a truncated cone shape, and a cylindrical guide pulley selectively combined with a bottom surface of the groove member and having a second guide groove formed on an outer circumferential surface thereof, wherein the wire is configured to move to the second guide groove of the guide pulley along the first guide groove of the groove member when the groove member combined with the cylindrical guide pulley rotates in a direction.
An outer diameter of the bottom surface of the groove member is formed to be larger than the outer circumferential surface of the guide pulley.
A combining protrusion is formed on the bottom surface of the groove member and a combining hole is formed in a lateral side of the guide pulley, wherein the combining protrusion of the groove member is selectively connected to with the combining hole of the guide pulley.
An end of the first guide groove formed on the outer circumferential surface of the groove member is connected with the second guide groove formed on the outer circumferential surface of the guide pulley when the groove member is combined with the guide pulley.
A top surface of the groove member is protrudedly formed with a bolt head.

As illustrated in
In this case, the outer circumferential surface of the groove member 100 may be provided with the wire W by forming the first guide groove 110 in a screw thread shape.
Meanwhile, a depth of the first guide groove 110 may be preferably formed so as to meet a height of the wire W.
The guide pulley 200 has a cylindrical shape so as to be combined with the bottom surface of the groove member 100.
In this case, an outer circumferential surface of the guide pulley 200 is provided with the second guide groove 210 so as to dispose the wire W thereon and a depth of the second guide groove 210 is formed so as to meet a height of the wire W.
Meanwhile, the bottom surface of the groove member 100 is provided with a combining protrusion 120 and the combining hole 220 is fitted in the top surface or the bottom surface of the guide pulley 200 so that the groove member 100 may be fixed to the guide pulley 200.
As such, the pulley assembly for wire combination according to the exemplary embodiment of the present invention may move the wire W formed in the first guide groove 110 to the second guide groove 210 of the guide pulley 200 along the first guide groove 110 having a screw thread shape when the groove member 100 is rotated by combining the groove member 100 provided with the first guide groove 110 with the guide pulley 200 provided with the second guide groove 210.
Here, the outer diameter of the bottom surface of the groove member 100 is formed to be larger than that of the guide pulley 200 and thus, the wire W can be naturally moved without being locked, when moving from the first guide groove 110 to the second guide groove 210.
Further, as illustrated in
Meanwhile, the top surface of the groove member 100 may be protrudedly provided with a bolt head 130 so as to combine the groove member 100 with a separate electric powered tool, thereby easily rotating the groove member 100.
That is, according to the exemplary embodiment of the present invention, when the groove member 100 is rotated by an electric powered tool while the combining protrusion 120 formed in the groove member 100 is inserted into the combining hole 220 of the guide pulley 200 to combine the groove member 100 with the pulley and then, the cable wire W to be assembled is locked to the first guide groove 110 of the groove member 100, the wire W is guided to the second guide groove 210 of the guide pulley 100 along the helical first guide groove 110 of the groove member 100 so as to be automatically mounted in the guide pulley 200. In this case, when the mounting of the cable wire W is completed, the groove member 100 may be separated from the guide pulley 200 to be used again.
