The present invention relates to a door opening and closing device of a self housing or a terminal, which is an electronic communication device, and in particular, a hook accommodation box is installed at an upper corner of a housing of the electronic communication device, and a fork-shaped locking door is combined. The semi-form is maintained properly by the external force up and down the locking hole, and the rail of the rubber material with good restoring force is combined with the roller coupled to the rail shaft. The present invention relates to a door opening and closing device for electronic communication equipment that is excellent, noise-proof, and can be used semi-permanently.

Conventional door opening and closing device is a door 20, 20a, 20b around the hinge 30, 30a, 30b in the self-housing (10), 10a, 10b as shown in FIGS. ) Is opened or closed in the lateral or longitudinal direction, and is locked to the brackets 50 and 50a using the door handles 40 and 40a, or the magnets on the front of the self housing 10b under the door 20b. 80b) is attached magnetically and closes.

By the way, the conventional door opening and closing device configured as shown in Figures 1 to 2 is not easy to assemble the door handles 40, 40a, there is a risk of injury to the operator during the assembly work and shock or vibration even when used after assembly. There was a problem that the door handle 40, 40a is released or the door is opened by an external force.

And the conventional apparatus for opening and closing the door by using the iron plate (90b) and the magnet (80b) configured as shown in FIG. 3 put the hand on the door opening and closing jaw (70b) when opening the door (20b) door (20b) The door 20b is attached to the magnet by magnetic force and closes even when it is closed.However, the production cost increases due to the large number of parts such as the iron plate 90b and the magnet 80b. Since the 90b is coupled and the door 20b is heavy, the hinge 30b may be damaged when the door is opened and closed. The door 20b may be opened by shock or vibration due to magnetic force.

In addition, there was a problem in that the production efficiency is not easy to assemble.

The present invention has been made in view of the above problems, and an object thereof is to provide a door opening and closing device of an electronic communication device which is excellent in tightening force when closing the door and can be prevented from being opened by an external force such as shock or vibration.

Another object of the present invention is to provide a door opening and closing device of an electronic communication device that smoothly opens and closes to suppress the occurrence of noise when opening and closing the door.

Another object of the present invention is to provide a door opening and closing device of the electronic communication equipment that can be used semi-permanently without opening and closing.

The object of the present invention is achieved by providing a door opening and closing device of the electronic communication equipment that can be used semi-permanently, which is prevented from being opened by the external force due to excellent fastening force and to prevent the opening and closing of the noise. The locking projection box is integrally installed at the upper corner of the housing, the fork-shaped latch is coupled, and the roller is coupled to the rail shaft support portions at the top and bottom of the latch. Detachable between the rollers to open and close the door.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 4 shows a door opening and closing device according to the present invention, the door opening and closing device is a locking device receiving box 11 and integrally formed on the upper edge of the main body (1) and the locking hole 6 coupled thereto, the locking hole A locking projection 7 attached to and detached from the 6 is formed in the door 2.

The catching hole receiving box 11 is provided with a catching hole 5 facing the opposite side walls, and a catching hinge receiving groove 5 'is formed in the longitudinal direction on one side wall.

The hook 6 is a U-shaped fork-shaped hook hinge 8 is coupled to the center, the reinforcement portion 10 is spoken in the vertical position up and down, the reinforcing portion 10 to the end of the circular rail The shaft support 9 is spoken.

And the rail shaft support portion 9 is coupled to the roller shaft (12) having a rail 13 made of a rubber material having excellent restoring force and elastic force at both ends of the rail shaft (14).

The latch projection 7 is installed at the proper position of the door 2 to be attached and detached between the rollers 12 of the locking opening 6 described above.

The hook 6 is coupled to the hook receiving box 11, the hook holes (8) formed at both ends of the hook receiving box 11 on both sides of the hook receiving box 11 formed in the hook (6) 5), firstly, one end of the latching hinge 8 is arranged in the locking hole 5, and the other end is passed through the latching hinge receiving groove 5 'formed in the longitudinal direction, and then in the locking hole 5. Just do it.

Reference numeral 3 in the accompanying drawings is a door handle, 4 is a hinge.

Then, as shown in (a) of FIG. 5, the door handle 3 formed on the outside of the door 2 is held, and the door 2 is closed. As a result, the hinge 4 coupled to the main body 1 and the door 2 is rotated. The door 2 is rotated clockwise.

Then, as shown in FIG. 5 (b), when the door 2 is continuously rotated, the locking protrusion 7 formed inside the door 2 is vertically connected to the locking hole receiving box 11. It passes between the rails 13 made of the solid member of the roller 12. When the locking protrusion 7 is partially inserted, the rail B of the rubber material is rotated in the direction of the arrow shown around the rail shaft 14. Some contractions.

And when the locking projection (7) is the top surface is inserted to the position on the center line between the rail 13, the upper and lower reinforcement portion 10 of the locking opening 6 is opened, the reinforcement portion 10 is to force to be restored as Will interact.

And as shown in (c) of FIG. 5, when the locking projection 7 of the door 2 passes between the rails 13 of the roller 12, the door 2 is closed and the locking projection 7 Is closely located between the rails 13 and the retracted rail 13 is returned to its original state and at the same time, the reinforcement portion 10 of the latching hole 6 that is opened is restored to its original position.

The operation of opening the door 2 proceeds in the reverse order when closing.

As described above, the door opening and closing device of the present invention opens and closes the door 2 while the locking protrusion 7 of the door 2 passes between the rollers 12 to which the rail 13 of rubber material having excellent restoring force and elasticity is coupled. Since the fastening force of the door 2 is excellent and it is prevented from being opened by an external force such as impact or vibration, and can be opened and closed smoothly without noise, it is a useful design that can be used semi-permanently while assembling and improving production efficiency.
