The present invention relates to a door lock for a toilet. More specifically, in constructing a guide display indicating whether the public toilet is in use, that is, "in use" or "empty", the first installation plate and the second installation plate are configured in two stages and the solar cell is used. (Solar Cell), PCB board, LCD panel, and a micro-switch to lock the toilet door lock.

1 is an exploded perspective view of a conventional toilet door lock, a lock 67 is installed inside the toilet door, and a guide display 60 indicating whether the toilet is used is installed outside the toilet door.

There are mechanical and electrical methods for indicating the use of the toilet, and an electric door lock using the solar cell 65, the PCB board 64, the LCD panel 66, the micro switch 69, and the like is illustrated in FIG. 1. .

As shown in FIG. 1, a perforation part 62 is formed in the case 61 of the guide indicator 60 so that the solar cell 65, the guide sticker, and the LCD panel 66 are recognized from the outside.

The PCB board 64, which is powered from the solar cell 65, is attached to the rear of the mounting plate 63, and the LCD panel 66 is connected to the PCB board 64, and the mounting plate is attached to the front sticker. It is mounted in front of 63. Since the installation plate 63 is built in the case 61, the case 61 is installed outside the toilet door.

A lock 67 for opening and closing is installed inside the toilet door, and a micro switch 69 for operating the PCB board 64 is installed inside the lock 67 as indicated by a broken line in the drawing. The operation of the micro switch 69 is a conventional method, and when the lock knob 68 is rotated, the lock bunch inside the lock 67 moves to open and close the toilet door and simultaneously touch the micro switch 69. The use of the toilet is displayed on the guide display (60).

The problem of the conventional toilet door lock described above is that the micro switch 69 is installed inside the lock 67, so that the socket 70 and the wire 72 for connecting to the PCB board 64 are outside the lock 67. Since it is exposed to the lock (67) on the toilet door there is a cumbersome point to insert the socket 70 and the connecting jack 71. In addition, since the solar cell 65 and the LCD panel 66 mounted inside the case 61 are directly exposed to the outside through the perforation part 62, water penetrates into the case 61 when the toilet is cleaned. The solar cell 65 and the LCD panel 66 as well as the PCB substrate 64 is damaged.

Therefore, the present invention was devised to solve the above problems, and the micro switch for controlling the PCB board is mounted in the guide display port, not the lock, and the solar cell and the LCD panel are directly exposed to the outside through the perforations of the case. The first door and the second mounting plate so as not to be mounted through the two-stage configuration, the lower part of the case to propose a door lock for the toilet, characterized in that the display handle is formed with a handle outside the toilet.

Hereinafter, with reference to the accompanying drawings the technical configuration and effects of a preferred embodiment which can achieve the object of the present invention will be described.

2 and 3 illustrate the internal structure of the guide display device 10 according to the present invention. As shown in FIG. 2, a perforation part 12 is formed in the case 11 of the guide display device 10. The solar cell 40 and the guide sticker 81 and the LCD panel 43 are recognized from the outside.

The guide 10 is to display on the outside the characters such as "in use" or "empty" which is the respective use state of the public toilet partitioned by a partition, it is installed outside the toilet door (80).

Inside the toilet door 80, the lock 50 shown in FIG. 3 is installed, and the characters such as "in use" or "empty" are displayed in the solar cell 40, the PCB board 41, and the LCD panel 43. ) And the electric switch using the micro switch 42 or the like.

The solar cell 40 is connected to the PCB substrate 41 to store the light of fluorescent and incandescent lamps installed in the bathroom so as to supply power to the PCB substrate 41 so as to be seen from the outside on the case 11 as shown in FIG. 5. The LCD panel 43 connected to the PCB substrate 41 by shorting the power supplied by attaching the microswitch 42 connected to the wire 46 to one side of the PCB substrate 41 as shown in FIG. 2. By operating the character of the guide sticker 81 attached as shown in Figure 5 to be selectively displayed according to the lock state of the lock (50).

The installation position of the micro switch 42 is conventionally installed inside the lock 67 (see FIG. 1), and the wire 72 is exposed to the outside. 46, see FIG. 4).

Meanwhile, as shown in FIG. 3, the transparent first mounting plate 20 is mounted inside the case 11, so that water that can flow into the toilet when the toilet is cleaned through the perforations 12 of the case 11 is installed in the first installation plate 20. Since it flows on the outer side of the 20, the electrical components of the solar cell 40, the PCB board 41, and the LCD panel 43 installed on the transparent second mounting plate 30 do not malfunction or fail due to water. Will be prevented.

A gap projection 21 is formed on the first mounting plate 20 to protect the surface of the LCD panel 43 interposed between the first mounting plate 20 and the second mounting plate 30.

In addition, a lock 50 shown in FIG. 3 is installed inside the toilet door 80, and the lock 50 has a square bar 52 as shown in FIG. 5 so as to be interlocked with the lock handle 51. The operation cam 44 can be operated by inserting the tip of the rod 52 into the fitting hole 45 of the operation cam 44 mounted on the settling 31 of the second mounting plate 30. .

The operation cam 44 has a rectangular shape, and the long side surface of the operation cam 44 is in close contact with the operation lever 42a of the micro switch 42 as shown in the enlarged view of the circle in FIG. 3. Thereafter, when the square bar 52 rotates, the surface of the LCD panel 43 is manipulated because the short side surface of the operation cam 44 touches the operation lever 42a.

6 is a schematic cross-sectional view for explaining the display handle 13 of the present invention, as shown in Figure 6 is displayed on the lower part of the case 11 so as to open and close the toilet door 80 by holding the guide display 10 as shown in FIG. A sphere handle 13 is formed. Thus, it is not necessary to install a separate handle to the toilet door (80).

After all, the present invention comprises a lock 50 and the guide indicator 10 in the door lock for the toilet to indicate whether or not the use of the toilet, the guide indicator (10) having a clearance projection 21 in the transparent first A transparent second mounting plate 30 on which the mounting plate 20, the solar cell 40, the PCB board 41, and the LCD panel 43 are installed is installed in a two-stage manner, so that water is washed in the case 11. The door lock for the toilet, characterized in that to prevent seeping into the interior.

In addition, the micro switch 42 is embedded in the guide display device 10 and connected to the PCB substrate 41, and the operation cam 44 for operating the micro switch 42 is installed in the second mounting plate 30. It is characterized in that it is mounted on the mounting fixture 31, and the display handle to hold the guide door (10) to open and close the toilet door (80) in the lower part of the case 11 of the guide display (10). (13) is formed.

Through the present invention as described above, since the socket for connecting with the guide indicator after the installation of the lock is not necessary, the efficiency of the work is increased, and through the installation of the two-stage method of the first installation plate and the second installation plate. Even when water penetrates into the guide when cleaning the toilet, there is an advantage that the PCB and the PCB as well as the solar cell and LCD panel are not damaged.
