1 to 6, a valve locking device 100 according to an embodiment of the present invention includes a cable 110, a main body 120, a fixing portion 130, and a regulating portion 140 do.

The cable 110 is made of metal, and one end of the cable 110 is installed in the main body 120 described later. The other end of the cable 110 is inserted into the main body 120 to be described later, passes through a space formed inside the fixed portion 130, and then is discharged from the main body 120. At the other end of the cable 110, a closure member 110a may be installed to facilitate insertion into the main body 120. A part of the cable 110 disposed in the space formed inside the fixing part 130 is pressed against the ball 133 of the fixing part 130 and is thus prevented from moving.

The outer surface of the cable 110 may be coated with an elastic material so as to improve gripping force and safety when gripped by a user.

One end of the cable 110 is installed in the main body part 120 and an internal space S1 is formed to communicate with the outside so that the other end of the cable 110 is inserted and then discharged to the outside.

A portion of the internal space S1 may be provided in an inclined shape corresponding to the shape of the base 132 of the main body 120 described later. One side of the body portion 120 forming part of this inclined-shaped internal space S1 may be contacted with a portion of the base 132, i.e., a tapered surface portion of the base 132, 132 to the tapered surface portion of the tapered surface.

Described fixing portion 130 is provided in the internal space S1 of the main body portion 120 described above.

The main body part 120 forms an opening space S2 which is a space in which one end face and the other end face are opened. The opening part S2 is provided with a control part 140 described later.

A locking hole is formed on the outer surface of the main body 120. The locking hole is provided with a diameter corresponding to the through hole formed in the adjusting part 140, which will be described later. When the lock L is installed in a state in which the lock hole and the through hole face each other, it is possible to effectively prevent the manipulation of the adjustment portion 140 from the outside.

Further, a tag hole may be formed on the outer surface of the main body 120 so that an identification tag can be attached.

Also, the main body 120 is preferably made of a metal material so as to be prevented from being broken or disassembled from an external impact.

The fixing portion 130 prevents the cable 110 from moving in the inner space S1 by contacting one surface of the main body portion 120 forming the inner space S1 and the cable 110, (S1). The fixing portion 130 includes a screw member 131, a base 132, a ball 133, and an elastic member 134.

The screw member 131 is disposed in the opening space S2 formed in the body portion 120 so that the adjusting portion 140 is screwed and the end portion is connected to the base 132 described later.

Since the screw member 131 is screwed to the adjustment member 140 as described above, when the adjustment member 140 rotates, the adjustment member 140 can move along the longitudinal direction of the screw member 131 have.

In addition, a space is formed in the screw member 131 so that the cable 110 can be moved after the cable 110 is inserted.

The base 132 is disposed in the inner space S1 formed in the main body 120, and the end of the screw member 131 is connected to one end. A space is formed in the base 132 so that the cable 110 passing through the screw member 131 is inserted and then moved.

The base 132 may be provided in a tapered shape corresponding to the internal space S1 provided in an inclined shape and a portion of the ball 133 described later may be exposed on the tapered surface. A ball 133 is provided.

When the tapered surface of the base 132 contacts one surface of the body portion 120 forming the inclined internal space S1, the ball 133 is pressed against the body portion 120 . Thereby, the ball 133 comes into contact with a part of the cable 110 passing through the inside of the base 132, so that the cable 110 is pressed, thereby preventing the movement of the cable 110.

According to the shape of the base 132 and the shape of the main body portion 120 forming the internal space S1, the cable 110 is connected to the other end of the cable 110 in order to allow the cable 110 to flow out from the main body 120 The ball 133 is brought into close contact with the surface of the main body 120 forming the inner space S1 more strongly so that the ball 133 can be prevented from being damaged by the tension applied to the cable 110. [ The cable 110 is more strongly urged to effectively prevent the cable 110 from flowing out to the outside.

The other end of the base 132 is provided with an elastic member 134 to be described later. Therefore, when the external force, that is, the force in the direction toward the other end of the cable 110 from the one end of the cable 110 is not transmitted to the base 132, The base 132 is always in contact with one surface of the main body portion 120 forming the internal space S1 by the elastic force applied to the end portion of the main body portion 120. As a result, (120). Accordingly, after the ball 133 contacts the cable 110, the cable 110 is pushed and the movement of the cable 110 is inhibited.

The ball 133 contacts one surface of the main body 120 forming the inner space S1 and the cable 110 to prevent the cable 110 from moving inside the base 132, 132, respectively.

These balls 133 may be provided in a plurality of tapered surfaces along the tapered surface of the base 132. [ As a result, the cable 110 can be pushed in various directions on the outer surface of the cable 110, effectively preventing the cable 110 from flowing out of the main body 120 by external force.

In addition, the ball 133 is rotatably installed inside the base 132. Accordingly, when tension is applied to the cable 110 in the direction from the one end of the cable 110 toward the other end of the cable 110, the ball 133 in contact with the cable 110 is rotated, The movement of the cable 110 can be guided.

Meanwhile, in the conventional valve locking device, that is, the valve locking device of Japanese Patent Application Laid-Open No. 10-2008-0107830, since the cable 110 is fixed to the plurality of projections formed on the upper plate member and the lower plate member, A large frictional force must be applied to the cable 110 in order to prevent the cable 110 from being released to the outside due to the tension applied to the cable 110. Therefore, the conventional cable lock 110 can not be applied to the conventional valve locking device, and a cable 110 coated with a coating layer of rubber material should be used.

As described above, according to the valve locking device 100 according to the embodiment of the present invention, since the balls 133 are pressed and pressed along the outer circumferential surface of the cable 110, the movement of the cable 110 is prevented do. Therefore, according to the method of fixing the cable 110 of the valve locking device 100 according to the embodiment of the present invention, regardless of the outer surface material of the cable 110, There is an effect that movement can be effectively prevented.

The elastic member 134 is compressed so that the cable 110 can move inside the base 132 when the external force is transmitted from the adjusting unit 140 to be described later so that the base 132 is separated from the main body 120 And is installed at the other end of the base 132.

The elastic member 134 receives external force from the adjusting unit 140 and is compressed. This compression causes the base 132 which has been in contact with the main body 120 to be disengaged from the main body 120 so that the ball 133 is disengaged from the main body 120, The cable 110 can be removed from the base 110 and moved within the base 132. [

When the external force is not applied to the elastic member 134, the elastic member 134 continuously applies an elastic force to the other end of the base 132, And the ball 133 presses the cable 110, and the movement of the cable 110 is prevented.

Therefore, according to the fixing unit 130 including the screw member 131, the base 132, the ball 133, and the elastic member 134, even if tensile force is applied to the cable 110, It is effectively prevented from moving in the inner space S1.

The control unit 140 transmits external force to the fixing unit 130 so that the cable 110 contacts the fixing unit 130 or the fixing unit 130 prevents the cable 110 from contacting the fixing unit 130. [ 130 in the opening space S2 and is installed in the screw member 131 of the fixing part 130 described above.

The adjusting portion 140 is screwed to the screw member 131 described above. Accordingly, when the adjusting portion 140 is rotated by the external force, the adjusting portion 140 can be moved along the length direction of the screw member 131. [ When the adjusting member 140 is moved along the longitudinal direction of the screw member 131 and reaches the position where the screw member 131 and the base 132 are connected to each other, the screw member 131 forms the opening space S2 And is in contact with one surface of the main body 120. Accordingly, the position of the fixing part 130 is fixed. At this time, the movement of the fixing part 130 can be prevented even if an external force, that is, a normal force is applied to the adjusting part 140.

In addition, a plurality of through holes, which can face the lock holes formed in the main body 120, may be formed along the circumferential surface of the adjuster 140. When the lock L is installed in a state in which the lock hole and the through hole face each other, it is possible to effectively prevent the manipulation of the adjustment portion 140 from the outside.

In addition, a plurality of grooves may be formed along the circumferential direction on the side surface of the regulating part 140. [ By this groove, the user can easily rotate the adjusting portion 140. [

Therefore, according to the adjustment unit 140, it is easy to insert the cable 110 into the main body 120 after the cable 110 is wound around the valve, to lock or release the lock.

Thus, according to the valve locking device 100 according to an embodiment of the present invention including the cable 110, the body portion 120, the fixing portion 130, and the adjusting portion 140, The movement of the cable 110 is effectively prevented.
