Abstract

PURPOSE: A locking device having four bolts of a manhole including optical cable reception holes is provided to maintain security of a communication manhole by using a disk cover and beeswax to hide a shape of a key and a shape of the locking device. CONSTITUTION: A locking push stick housing(33) and a crossing bar(30) for supporting the locking push stick housing(33) are located at a lower part of a hood disk(10). The locking push stick housing(33) and the crossing bar(30) are arranged at a center hole(14) of the hood disk(10). The center hole(14) is covered by a center hole cover(15). Four locking push sticks(31) are moved by pushing four grating rings. The locking push sticks(31) are inserted into four reception holes by pushing four grating rings. A door is closed after the locking push sticks(31) are inserted into four reception holes. A hook is adhered to the center hole cover(15) in order to maintain a locking state of the center hole. Beeswax is used for hiding a concave part corresponding to a key of a keyhole. In addition, a keyhole cover is located on the keyhole.

Description

{A safety catcher with Four square stick holders under a lid of manhole to protect for the optical fiver telephone cables.}

The present invention is that the acceptance lock device is inherently open and can be opened by anyone mechanical operation, which is insufficient for the protection of the communication line. This tricky, time-consuming and complicated method is available only to those who have fully recognized the method in advance.The system can be easily opened and locked for the underground laying of existing optical cable networks and occasional sewage. will be.

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 to be achieved by the present invention is that the locking device is located under the lid made of steel or stainless steel of the receiving hole, so that the conventional key insertion hole is located at the center, so that the key is opened by rust or rain water. (開口) The blockage or inability to open with a hammer or a pickaxe to delay the work is a lot of damage to the closed end of the concept of the finished product of FIG. .

The material of the present invention is the cost comparison that the use of SUS 304 in both the original plate and the skeleton of the steel sheet is cheap compared to the cost of rust or damage later replacement, the main configuration was made to the size of the plate But first, they were classified into large, medium, and small.

And the material is the standard stick of the push rod zigzag (30) that is attached to the inner bottom of the disc lid (10) of the acceptance hole is 1005mm × 505mm × thickness 3mm and medium 704 mm x 3 mm thick, small 595mm × thickness 3mm, spring 32 for supporting and releasing the latch lock rod 31 is 1.5t steel wire of SUS 304 1.5t steel wire, composed of two 250mm ones It consists of one piece of 500mm. In addition, the key holder cover (23), that is, the key insertion hole (hole) should be raised to fill the wax (40). 15mm is good.

The latch lock pusher (33) is a square square pipe, the standard is SUS 30, 50mm square tube, 1.5mm thick, 195mm long, 2 225mm long, and supports the bar outward. 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 locking device on the inside of the disc lid (10) lock rod (31) at the four ends of the disc cap 10 to fit the size of the receiving hole with 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 lock rods 31, first, the lock rods 33 are positioned so that four lock rods 31 are pushed to the A-shaped lattice ring 37 at the center ball 14 at four places. The lock push rod release support spring (32) must be put into the push rod house 33 so that the lock push rod 31 extends into 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 cover and reopen the lid 10, 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 with the oval plate (18) while the key key (17) on the bottom rotates 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 inner support bar (15) is also SUS 30. The size is 16mm long x 1.5mm thick, two 195mm long and one 225mm long, and the support rod 16 uses 5 SUS 40 t angles. 50mm long and 15mm long, and the connecting rod was made of 2 pieces of 40mm of SUS 40, and the lower cover plate 24 of the disc was made of 1mm of 230mm of 3 t, and other spring lock bolts of 6 bolts Six 6mm and STOPPER parts were used to form 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 seal lock device is manufactured and completed in this way, when the rod key 20 is inserted into the key hole located in the center of the disc, the wax 40 is heated and filled in the hole so that the shape of the key cannot be seen. Those who are rusted or not rusted or who do not know the present invention will not be able to open the acceptor because the key is not correct.

In the above, the present invention hopes that the shape of the key and the locking device will be invisible to the disc cover and beeswax, so that the product will not be known to anyone other than the person who installed it. It is possible to prevent economic losses such as the elimination of the risk of cutting, cutting, communication disturbance and repair work in the telephone station.

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.
