The present invention relates to a soundproof door locking device, and more particularly, to a soundproof door locking device for precisely opening and closing a door in a soundproof place, such as a recording room or a sound control room using a broadcasting station or other sound equipment of a broadcasting station. It is about.

In general, in a broadcasting room or a sound control room, noise generated when opening and closing a door panel that needs to be closed in close contact with the door frame and the door panel to prevent sound from being separated from the outside should also be prevented.

As described above, the soundproof door locking device applied to the soundproof door is partially disclosed in Practical Publication No. 1996-5220, which is a schematic description of the soundproof door locking device of the prior art by FIG.

It consists of a handle 10 and a locking guide 12, which is provided with a bundle of keys (8) on the fixing plate (6) which is installed inside and outside the door panel (4) of the soundproof door (2). The handle 10 is integrally formed with a protruding pressure rod 14. When the door panel 4 is locked, the pressure rod 14 slides the locking guide 12 by the rotation of the handle 10 to lock the door panel 4.

When the door panel 4 is in close contact with the door frame 16 in the soundproof door 2, the handle 10 is rotated so that the pressure rod 14 slides upward from the lock guide 12 surface. do. The locking guide 12 is formed so that the upper side is thicker than the lower end to exert the pressing force.

However, the pressure rod 14 has a problem that wear and friction noise occurs because the pressure rod 14 must be closely contacted with a large force while overcoming the weight load of the door panel 4 when sliding the locking guide 12.

In addition, there is a problem that the acoustic control is not properly made because the close contact is not made due to deformation of the pressure rod 14 and the lock guide 12 wear.

It is proposed to solve the problems of the prior art as described above, the object of the present invention is to accurately open and close the door of the soundproof place, such as a recording room or sound control room using a broadcasting room or other sound equipment of a broadcasting station. Soundproof door locks are provided to ensure proper acoustic control.

In order to achieve the above technical problem,

A fixed plate mounted on the inner and outer surfaces of the door panel;

A connection pipe installed to be assembled to receive the bundle of keys while being inserted into the fixing plate;

A handle rotating shaft unit configured to rotate the handle around the key bundle accommodated in the connection pipe;

A locking pressing roller which is formed at a predetermined angle with respect to the handle formed on the handle rotating shaft part and is installed to be rolled along the roller guide surface of the door frame;

It provides a soundproof door lock, characterized in that configured.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

Figure 2 is an exploded perspective view showing a soundproof door locking device according to the present invention, Figure 3 is a perspective view showing the soundproof door locking device of FIG. 4 is a side cross-sectional view of the locking pressing roller of FIG. 3, and FIG. 5 is a view showing that the locking pressing roller of FIG. 3 is located in a locked state. 6 is a view showing the operation of the soundproof door lock in FIG.

Referring to the drawings, the soundproof door locking device 20 is composed of a fixed plate 22, the connection pipe 24, the handle rotating shaft portion 26, the locking pressure roller 28.

Fixing plate 22 is mounted on the inner, outer surface of the door panel 30, the spring spring 31 is interposed to facilitate the restoring operation of the handle shaft 26. As the fixing plate 22 forms a boss 22-1 protruding toward the front side, the handle 26-1 is spaced apart from the surface of the door panel 30 to facilitate gripping and easy operation. .

The connector tube 24 is an assembly member for connecting the fixed plate 22 and the handle rotating shaft part 26, and a bundle of keys 24-1 is assembled therein. The key bundle 24-1 assembled to the connection pipe 24 is assembled to operate organically with the fixing plate 22 and the handle rotating shaft part 26 by a conventional method.

The handle shaft 26 is assembled with a connection tube 24 in which a bunch of keys 24-1 are accommodated in a rotation center hole 26-2 formed at the center thereof. The handle rotating shaft portion 26 extends the handle rod 26-3 to one side, and the handle 26-26 is assembled with a handle cover 26-4 made of a resin material without slipping therein and is easily gripped. ).

And the handle rotating shaft portion 26 is provided with a locking pressure roller 28 at a position at a predetermined angle with the handle 26-1. The locking pressure roller 28 is installed to move along the roller guide 34 surface so that the door rotating shaft 30 is pressed against the handle rotating shaft part 26 to lock the door panel 30 to the door frame 32.

In the roller guide 34, the upper side is high and the lower portion is formed in a low shape, so that the locking of the door panel 30 is made airtight when the locking pressing roller 28 moves upward.

The locking pressure roller 28 has a protrusion 26-6 having a fastening hole 26-5 formed at the handle rotating shaft portion 26 and a washer 28-1 disposed on the surface of the protrusion 26-6. A pin roller 28-3 assembled in the 28-2, an inner ring 28-4 inserted to support the pin roller 28-3, and a protrusion 26 passing through the inner ring 28-4. -2) is composed of a fixed shaft bolt (28-5) that is screwed after assembling in the above order in the fastening hole (26-5).

The outer ring 28-2 is rotated to roll along the roller guide 34 surface, the cloud is easily made by the pin roller (28-3). The rollers 28-32 are supported by the roller supporters 28-31 and assembled so that the pin rollers 28-3 work on the outer circumferential surface of the inner ring 28-4.

4, 5, and 6, the soundproof door 36 installed in the broadcasting room and the studio is airtightly installed to facilitate sound control.

The soundproof door 36 is locked after being pressed to close the door panel 30 when the door panel 30 is closed to the door frame 32. The lock pressing roller 28 is rolled on the door frame 32 along the surface of the installed roller guide 34 formed to be inclined at an angle.

Then, if sound control is required in a broadcasting room, a recording studio, or a studio, the door panel 30 is pushed toward the door frame 32 side, and then the handle 26-1 is slightly turned to lock the pressing roller 28 by the roller guide. Manipulate so as to hook the bottom surface of (34).

When the door panel 30 is prepared to be closed to the door frame 32 as described above, the user turns the handle 26-1 completely. At this time, the handle rotating shaft portion 26 is rotated in the clockwise direction with the center of rotation of the connecting tube 24, the key bundle (24-1) is assembled.

As the handle rotating shaft portion 26 rotates in the clockwise direction, the locking pressure roller 28 on the roller guide 34 is rotated by the pin roller 28-3, and the outer ring 28-2 rotates to obtain a predetermined thickness. It is positioned horizontally on the upper portion of the roller guide 34 (see Fig. 5).

As the locking pressure roller 28 of the handle rotating shaft portion 26 becomes a horizontal posture, the door panel 30 is closed in an airtight state in close contact with the door frame 32 to enable accurate sound control.

As described above, the soundproof door locking device has an effect that the door panel is pressurized and locked securely to the door frame of the soundproof door by rolling the pressure roller to lock the roller guide surface installed on the door frame.

Since the locking pressure roller of the handle is easily rotated along the roller guide surface of the door frame, there is an effect that the locking locking of the door panel is conveniently performed with little force.

When the handle is rotated, the roller guide surface is easily rotated by the locking pressure roller, and the door panel is pushed against the door frame by pressing the door panel, thereby increasing the sound insulation effect.

In addition, as the locking pressure roller rolls along the roller guide surface, the pressure locking of the door panel is performed, thereby preventing noise when closing, which is effective for sound control of a broadcasting room or a sound control room.
