[Field of Invention]

The present invention relates to a mop mounting rod for a vacuum cleaner.

In particular, the present invention relates to a rotation control apparatus of the mop mounting rod. More particularly, the present invention relates to a rotation control apparatus for a mop attachment rod that is simple in structure and can fully utilize the outer surface of the mop attached to the mop attachment rod.

[Background of invention]

As shown in FIG. 1, the conventional mop is attached to the mop attachment rod, and the mop attachment rod having a rotation control device for controlling rotation of the mop attachment rod itself at both ends thereof has both sides of the housing constituting the suction brush. It is fixed to the rotatable. The rotation control device suppresses the rotation of the mop attachment rod when advancing the suction brush, and rotates the mop attachment rod in one direction only when the suction brush is reversed.

Therefore, when the suction brush is moved forward, the rotation of the mop attachment rod is stopped, so that the mop attached to the mop attachment rod is also stopped and cleaned with the surface in contact with the floor, and when the suction brush is reversed, the mop attachment rod is rotated. As a result, the unpolluted part of the mop is brought into new contact with the floor. Accordingly, the mop is configured to be cleaned at the contact portion while rotating sequentially.

However, in the vacuum cleaner employing such a conventional mop mounting rod, four or six spiral grooves of the rotating plate formed in the rotation control device are constructed, and each of the spiral grooves has the same specification with the same angle and length. The surface itself is formed to be stopped after the rotation is limited by this constant. That is, when the suction brush is rotated several times during the reverse movement of the suction brush, the spiral groove which stops the rotation when the suction brush is advanced again has the same length and angle. Therefore, the contact surface formed by the suction brush is also perpendicular to each other when four spiral grooves are formed. Four contact surfaces are formed, and in the case of six spiral grooves, six contact surfaces are formed at an angle of 60 ° with respect to each other. This contact surface is applied to the mop as it is, so that only the four contact surfaces formed in the same mop contact the actual floor, resulting in the entire outer peripheral surface of the circular mop is not utilized.

In addition, the conventional mop mounting rod has a rotating shaft (1), mop mounting shaft (2), a cylindrical groove formed with a spiral groove (3), a locking plate (4), a spring (5), two stators (6) and a case (7) at least It consists of 7 to 8 parts, so despite the simple function, the number of parts is too large, the time required for assembly is excessive, the productivity is lowered, and the price is increased.

In addition, the rotation control device described in the pending patent application No. 92-25585 (name of the invention: a mop rod rotation control device of a vacuum cleaner), which is patented in Korea by the inventor, is also formed on the cam plate between the cam plate and the track. The tip between the tracks is built in the cam track and rotates in a predetermined direction according to the shape of the cam, and then forms a predetermined interval, that is, a predetermined angle, and is fixed so as to contact the floor while rotating the mop sequentially.

The mop rod rotation control device is also rotated by a predetermined angle formed by the cam track, and then only the contact surface formed to be fixed is in contact with the floor to use only a limited area of the entire surface of the mop.

Therefore, in the conventional mop mounting rod, instead of using the spring (5) and the locking plate (4) developed a mop mounting rod using a hook that descends by gravity to solve the above problems and the present invention Was completed.

[Purpose of invention]

An object of the present invention is to provide a rotation control device of the mop mounting rod.

Another object of the present invention is to provide a rotation control device for a mop mounting rod.

Still another object of the present invention is to provide a rotation control apparatus for a mop attachment rod that is simple in structure and can fully utilize the outer surface of the mop attached to the mop attachment rod.

[Summary of invention]

It is an object of the present invention to provide a rotation control apparatus for a mop attachment rod that is simple in structure and can fully utilize the cleaning outer surface of the mop attached to the mop attachment rod.

In the present invention, the rotation control device of the mop mounting rod of the vacuum cleaner is fixed around the rotary shaft, the rotary shaft, the mop mounting shaft for mounting the mop, the support shaft for increasing and decreasing the outer diameter of the mop mounting shaft is coupled to both ends of the mop mounting shaft And a mop mounting rod comprising a stator, wherein a spiral groove is formed on an inner surface of at least one support shaft among the support shafts supporting the mop mounting shaft, and a downward groove is formed on the stator on one side, and the spiral groove of the support shaft. It is coupled to the characterized in that it further comprises a locking member to move up and down in accordance with the rotation of gravity and the support shaft along the down groove of the stator.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[Description of Specific Example of the Invention]

As shown in Figure 2, the rotation control device of the mop mounting rod of the vacuum cleaner according to the present invention is a rotation shaft, the mop mounting shaft 12 is fixed around the rotary shaft for mounting the mop, the mop mounting shaft 12 In the mop attachment rod consisting of the support shaft 13 and the stator 16 coupled to both side ends of the mop attachment shaft 12 to increase and decrease the outer diameter of the mop attachment shaft 12, the support shaft for supporting the mop attachment shaft 12 ( At least one of the 13 is formed with a spiral groove on the inner surface of the support shaft, the lower groove 15 is formed in the stator 16 of the one side, is coupled to the spiral groove of the support shaft 13 is the stator 16 It characterized in that it further comprises a locking member 14 to move up and down in accordance with the rotation of the support shaft 13 and gravity along the lower groove (15).

The mop mounting rod has an outer diameter that changes according to the insertion and withdrawal of the support shaft 13 toward the mop attachment shaft 12, that is, when the support shaft 13 is withdrawn, the outer diameter decreases to facilitate the installation of the mop. When the support shaft 13 is inserted, the outer diameter is increased so that the inserted mop is fitted to the mop mounting shaft 12 so that the cleaning shaft is in a state capable of cleaning. The present invention is described in more detail in the pending patent application No. 92-25586 (inventive name: rotary mop brush for vacuum cleaner) by the present inventors, and the present invention relates to a rotary mop brush according to the patent application. It is a further improvement of the rotation control device attached to both ends.

Rotating control device of the mop mounting rod according to the present invention is formed to the spiral groove on the inner surface of the conventional support shaft 13 is configured to move the catcher 14 along this spiral groove is formed in the stator 16 falling groove With (15), rotate the mop mounting rod only by one angle.
