Abstract

The present invention relates to a secure take-out lock device for managing communication lines. Accordingly, specially designed opening and closing of the lid in the take-in and take-off area is opened and closed so that only the administrator can open and close the complete communication security in the first line area for communication security. The whole device is made of stainless steel or general materials, and the key and the latch hanger is configured to operate as a body so that it can not be opened and closed other than the present invention.

Therefore, it is the same as for general industrial safety except for the acceptance lock key, and it is characterized by a temporary method of melting the lock key ball with a special wax to use it for opening and closing.

Description

Safety catcher under the lid of public manhole to protect for the optical fiver telephone cables as four square stick holders.

Prior to this design, the lock-in-lock device was originally open and closed for communication line management. Anyone can open it. Now, due to the importance of communication security, it is now available in a new way that only the designated person can open. It was devised by adding the opening and closing method, and only those who recognized the present invention could unlock and open the lock of the cap of the receiving hole where the communication cable is installed.

The conventional problem is that even if there is no key required for opening and closing, it is installed in a state where it can be seen overflowing too much, so that the keyhole is opened, so that opening and closing is possible even with a general tool.

Particularly in the general situation, in the meantime, the acceptance lock is inherently open and can be opened by mechanical operation. Therefore, it is insufficient to protect the communication line. Key cloning method is difficult and time-consuming, and it is a complex application that can be done only by those who are fully aware of this design method, and it can be easily opened and locked for the underground laying of existing optical cable network and occasional sewage. I did it in a way that I could.

In addition, the locker loses its function due to moisture, dust, etc. in the natural state, such as the locker located on the road and rain, wind, or even traffic, not only a simple locking device, but also expensive electronic devices. Despite its excellent installation, rusting and losing its function can remind us that if the inner lid is broken and opened, there may be a possibility of breakage and even a disturbance in communication.

The technical problem of the present invention is that the locking device is located under the cap made of steel or stainless steel of the receiving hole, and the key opening is positioned in the center, so that the key is opened by rust or rain water. Opening with a hammer or pickaxe due to blockage or incapacity to the function will delay the work and create a finished product of FIG.

The material of this design is the main composition because the standard of steel plate is SUS 304 for both the original plate and the skeleton, which is cheaper compared to the cost of rust or damage and replacement later. But first, they were classified into large, medium, and small.

The material is 1005mm × 505mm × 3mm thick and medium size φ704mm × 3mm thick, and the small size is φ595mm × 3mm thick. 31) The spring 32 for supporting and releasing is composed of two 1.5t steel wires φ250mm of SUS 304, and is composed of one 1.5t steel wire φ500mm. In addition, the key holder cover 23, that is, the key insertion hole (hole) should be raised to fill the beeswax, the diameter is good φ15mm.

The latch lock pusher (33) is a square square pipe. The standard is a 50mm square tube made of SUS 30. It is 1.5mm thick, 195mm long, 2 long, and 225mm long. For the hook lock rod 31 is as follows.

In the detailed configuration of the present invention, as shown in Figure 1 attached to the lock on the inside of the disc lid 10, the locking rod (31) at the four ends of the disc cap 10 according to the size of the receiving hole by the letter + After mounting the four a-shaped lattice ring (37) to push the lock pusher cover the central ball cover (15) made in the center of the lid (10) four a-shaped lattice ring (37) is pressed while the vertical plane is pushed (a) 31) is pushed to the end of the lid (10) to extend to the bottom of the receiving hole to be locked.

Therefore, in order to securely attach the four and the lock rods 31, first, the lock rods 33 are positioned so that four lock rods 31 are pushed to the a-type lattice ring 37 at the center ball 14 at four places. The lock push rod release support coil spring 32 must be manufactured in the push rod 33 so that the lock push rod 31 extends to the central ball 14 at all times.

Four pusher houses 33 are arranged in a + shape, and the pusher house fixing blinds 30 are made of + to be fixed so that they are centered about the center ball 14 so that the pusher house 33 can be accurately received. Make the push rod 31 go inside.

A grid grating (37) is easy to operate by attaching bolts and nuts to four quarters of the edges of the center ball (14) so that they do not overlap with the bolts and nuts for mounting the center ball cover (15) to cover the center ball (14). something to do.

To close the lid 10 and reopen it, heat the end of the key 20 with a burner or the like to melt the hard wax 40 that has already melted before putting the key 20 into the key hole 22. The key ring (17) turns the key ring (17) with the elliptic plate (18) as the iron key (28) on the bottom turns while melting the wax (40) in (27). The disc cover (10) is removed from the hook (16) and the central hole (14) is opened and the spring (32) with the a-shaped lattice hooks (37) in the pusher housing (33) is sucked out of the lock pushers (31) in the receiver. ) To open the disc handle (11) by pulling it open.

In order not to move the lock pusher house 33 is forcibly pulled out, only two places of the separate lock pusher barn fixing annular metal plate 35 spread in a + -shape.

The length of the support bar (15) is also SUS 30. The size is 16mm in length × 1.5mm in thickness, 2 pieces of 195mm in length, and 1 piece of 225mm in length.The supporting rod 16 is 50mm long by using SUS 40 piece 5t angle. 2 pieces and 1 length 15mm, and the connecting rod was 2 pieces of 40 mm of SUS 40, and the lower cover plate (24) was made of 1 piece of 230mm of 3t. The parts were made of two 300mm handles with 8mm round rods.

The key 23 was an 8 mm round bar with a length of 300 mm, a board of 15 mm and a length of 15 mm, and a pipe of 16 mm and a length of 15 mm.

When the key lock 20 is inserted into the key hole located in the upper center of the disc, the receiving hole lock device manufactured as described above can not see the shape of the key if it is heated and filled with the wax 30 in the hole. Those who are rusted or not rusted or who do not know the invention will not be able to open the job because the key is not correct.

The above invention hopes that the shape of the key and the locking device will be invisible by the disc cover and the beeswax, so it will be a product that only the person who installed it will be able to know. Therefore, the security of the communication manhole can be permanently preserved. Eliminate risks caused by cutting, cutting, communication disturbances and economic losses such as recovery.

This key and key bundle can be applied to all industries that require safety and security, so it can be applied to all industries requiring safety and security.
