Description

Locking device for communication terminal box {LOCKING APPARATUS OF COMMUNICATION TERMINAL BLOCK BOX}

The present invention relates to a lock of the terminal box for communication.

The terminal box for communication means that the terminal to which a communication line such as a telephone line is connected is integrated. Referring to Figures 1a and 1b it will be described that the conventional terminal box is locked and released. Figure 1a is a view showing a conventional terminal box locked state.

As shown, the main body 10 is provided. The main body 10 has a lower case 11 and a cover 13 which are hinged to each other with respect to one side. The lower case 11 and the cover 13 seal and open the inside of the body 10 while being in contact with and separated from each other. The lower protrusions 11a and the upper protrusion tube 13a are formed on the outer surfaces of the lower and the covers 11 and 13, respectively, and the lower protrusion tube 11a and the upper protrusion tube 13a are fastened by the fastening member 17. Are integrally combined. That is, when the fastening member 17 is inserted into the upper protrusion tube 13a and the driver 20 is inserted into the groove 17a formed in the head of the fastening member 17, the lower protrusion tube 11a and the upper protrusion are turned. The tube 13a is integrally coupled. Then, the lower case 11 and the cover 13 are kept locked to each other.

However, the conventional terminal box locking device as described above has a disadvantage that anyone can easily release. In detail, the fastening member 17 can be separated from the lower protrusion tube 11a and the upper protrusion tube 13a by using a screwdriver, a nail clipper, and even a coin. Therefore, there is a fear that a person other than the worker can open the main body and arbitrarily change the communication line connected to the terminal pins of the main body. This may cause an accident such as a bad connection or a wrong connection.

Figure 1b is a view showing another conventional terminal box is locked, the lower latch 11b and the upper latch 13b are formed on the outer surface of the lower and cover 11, 13, respectively, the lower and upper latch 11b, The lock 30 is filled in 13b) to lock the lower case 11 and the cover 13.

The conventional terminal box as described above has a disadvantage that the work is cumbersome because the lock must be locked and released using a separate key. In addition, there is a disadvantage that the cost increases because you need to purchase a separate lock and key.

The present invention was created to solve the above problems, the object of the present invention is to provide an economical communication terminal box and its locking device as well as easy locking and unlocking only by the operator.

As shown, a main body 100 having a cover 110 and a lower case 120 which are hingedly coupled to each other is provided. The outer surface of the cover 110 and the lower case 120 is provided with a cylindrical upper protrusion tube 111 and the lower protrusion tube 121 to face, the inner peripheral surface of the upper protrusion tube 111 and the lower protrusion tube 121 Screws 113 and 123 are formed, respectively.

The upper protrusion tube 111 and the lower protrusion tube 121 are integrally coupled by the fastening member 130, thereby maintaining the cover 110 and the lower case 120 is locked.

The fastening member 130 has a cylindrical body 131 and a cylindrical head 133. The outer circumferential surface of the body 131 is formed with a screw 131a engaging with the screws 113 and 123 of the upper and lower protrusion pipes 111 and 121. The head 133 extends and is formed at one end of the body 131, and has a diameter larger than that of the body 131 to be in contact with and supported by the upper surface 111a of the upper protrusion pipe 111. That is, when the bottom surface of the head 133 is in contact with the upper surface (111a) of the upper projection tube 111, the fastening member 130 is no longer inserted into the upper and lower projection tubes (111, 121).

The fastening member 130 and the upper and lower protrusion tubes 111 and 121 are coupled by engaging the screws 131a and the screws 113 and 123. That is, when the fastening member 130 rotates forward and backward, the fastening member 130 is coupled to the upper and lower protrusion tubes 111 and 121 while being lifted along the upper and lower protrusion tubes 111 and 121.

In this embodiment, the rotating member 140 for easily rotating the cylindrical fastening member 130 is provided. The rotating member 140 has a coupling pipe 141 inserted into and detached from the head 133 of the fastening member 130 and a butterfly-shaped handle 143 extending from one end of the coupling pipe 141.

When rotating by applying an external force to the handle 143, the locking projection 141a and the locking path 133a for accurately transmitting the external force applied to the handle 143 to the fastening member 130, the rotating member 140 and It is formed on the fastening member 130, respectively. The locking path 133a is formed in a form recessed on the outer surface of the head 133 of the fastening member 130, and the locking protrusion 141a is locked to the inner surface of the coupling pipe 141 of the rotating member 140 ( It is formed in the shape corresponding to 133a).

In this embodiment, the fastening member 130 is provided to be fastened and separated from the upper and lower protrusion tubes 111 and 121 by using only the rotating member 140. To this end, a protective tube 150 having a frame shape is provided on the upper surface 111a of the upper protrusion tube 111. The height H1 of the protective tube 150 has a height higher than the height H2 of the head 133 of the fastening member 130, and surrounds the side surface of the head 133 of the fastening member 130. Prepared. That is, the head 133 of the fastening member 130 is completely inserted into the protective tube 150 so that the head 133 of the fastening member 130 may not be caught outside the protective tube 150.

Then, the thickness D between the inner surface of the protective tube 150 and the outer surface of the head 133 of the fastening member 130 and the coupling tube 141 of the rotating member 140 are equally provided. , Only the coupling tube 141 of the rotating member 140 is inserted. Then, it is impossible to separate the fastening member 130 from the upper and lower protrusion pipes 111 and 121 except the person who owns the rotating member 140. At this time, the thickness T of the coupling pipe 141 is preferably formed around 1mm.

Figures 4a and 4b is shown to lock the terminal box using a locking device according to an embodiment of the present invention, a cross-sectional view taken along line A-A of FIG.

As shown, after slightly inserting the end of the body 131 of the fastening member 130 into the upper protrusion tube 111, the coupling tube 141 of the rotating member 140 head of the fastening member 130 Inserted in (133). Then, when the rotating member 140 is rotated forward, the fastening member 130 is lowered and is fastened to the upper and lower protrusion pipes (111, 121). Then, the cover 110 and the lower case 120 are integrally coupled and locked.

When the fastening member 130 is to be separated, the coupling pipe 141 may be inserted between the protective pipe 150 and the head 133, and the rotating member 140 may be reversely rotated.

As described above, the locking device of the communication terminal box according to the present invention, by using only the rotating member can fasten and detach the fastening member to the upper and lower cases. Therefore, the terminal box can not be opened or closed except by the person concerned, and the components inside the terminal box can be stored safely.

It's also economical because you don't have to buy extra locks and keys.

In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention belongs without modification and modification within the scope without departing from the technical spirit of the present invention. Of course.
