Accordingly, in the present invention, it is preferable that the wall surface 122 of the locking groove 120 on the position where the locking means is not provided is provided with at least one or more collision cushioning materials SB sandwiched therebetween.

That is, a through hole is formed in the inner wall surface 122 of the locking groove 120, and the impact buffering material SB passes through the through hole and a part of the impact buffering material SB is exposed to the side of the locking groove 120, The cabinet door D is cushioned so as not to come in contact with the inner wall surface 122 when the cabinet door D is closed so that the cabinet door D and the front post 100 do not directly bump into each other to prevent glass breakage or contact noise.

Therefore, the collision cushioning material SB is preferably made of a stretchable material such as rubber or plastic.

In addition, a fixing boss 140 protruding from the inner side surface and integrally extruded is protruded inside the front post 100.

The fixing boss 140 is a means for screwing the top cover 700 and the bottom base 800. Although not shown in the drawing, the fixing boss 140 is formed to penetrate through the top cover 700 and the bottom base 800 in the thickness direction And then screwed in the fixing boss 140, so that they can be securely fixed.

A plate insertion groove 150 is formed on a surface of the front post 100 opposite to the side where the cabinet door D is installed.

The plate inserting groove 150 is formed by extruding two protruding pieces 152 so as to have a substantially C shape so that the side plates S1 and S2 are inserted into the plate inserting groove 150, respectively.

5, a rack frame fixing piece 160 is integrally formed on the same surface at a distance from the plate insertion groove 150, and a rack can be fixed to the rack frame fixing piece 160 The rack frame 170 is installed symmetrically.

In this case, it is preferable that fasteners 172 are formed on the upper and lower ends of the rack frame 170 so as to be screwed on the rack frame fixing pieces 160.

In addition, the slide guider 190 opened to the front while being orthogonal to the rack frame fixing piece 160 is elongated in the downward direction, and the insert tab 192 is inserted into the slide guider 190.

The insert tab 192 is a plate having a substantially rectangular shape and is a member having a plurality of tab holes 194 such as three, six, or nine tabs spaced apart in the longitudinal direction, and a plurality of the insert tabs 192 are stacked on top of each other .

Particularly, the insert tab 192 is a means for guiding the sub rack 20 (see FIG. 1) described in the prior art to be mounted.

A door contact surface 180 is formed between the bar fixing surface 130 and the locking groove 120. The door contact surface 180 has a function of stopping the cabinet door D from rotating inwardly .

On the other hand, as shown in FIGS. 3, 6, 7 and 8, the upper rear bar 400 and the lower rear bar 600 are fastened to the upper and lower ends of the pair of rear posts 200, respectively. At this time, the method of fastening the upper and lower rear bars 400, 600 and the rear post 200 may be changed to a form of welding or assembling and press-fitting.

To this end, the rear posts 200 are extruded to have a substantially rectangular cross section, and protrusions 210 of a certain width protrude from the center of the pair of facing surfaces.

The protrusions 210 are bent in a shape corresponding to the corresponding ends of the upper rear bar 400 and the lower rear bar 600 to be guided to have a fitting structure of a kind. When the rear bars 400 are grounded, Fixed through the fixing screw 212, and fastened by welding.

The locking pieces 220 of the rear door B and the rotary shafts 230a and 230b are moved in the opposite directions to each other to form the same locking structure So that the opening and closing directions of the rear door B are not restricted. This is the same as the reason for installing the cabinet door D.

8, the locker 222 may be engaged with the protrusion 210 according to the rotation direction of the lock member 220, So that it can be locked or unlocked.

As shown in FIG. 6, the rotary shafts 230a and 230b are provided on the opposite sides of the lock member 220, and serve as rotation centers of the rear door B. As shown in FIG.

In this case, unlike the above-described hinge H, the rotary shafts 230a and 230b are divided into a lower rotary shaft 230a and an upper rotary shaft 230b, which have different structures.

For example, the lower rotation shaft 230a is welded and fixed to the lower end surface of the rear door B, including a cylindrical projection 232 having a larger radius. Of course, because the axial bushing 234 is present, the basal spacing is maintained, so that the projections 232 need not be provided. Therefore, the projecting portion 232 of the lower rotary shaft 230a and the axial bushing 234 may be used only one, or both, depending on their roles.

A rotary shaft groove YB1 is formed on the lower rear bar 600. A shaft bushing 234 is inserted into the rotary shaft groove YB1 and the lower rotary shaft 230a is inserted into the shaft bushing 234 And is in a state in which it is rotatable. Here, the axial bushing 234 may be omitted as needed. That is, when the shaft bushing 234 is not provided, the lower rotary shaft 230a is directly fitted into the rotary shaft groove YB1.

At this time, the protrusion 232 is retained without being caught by the shaft bushing 234, thereby maintaining a gap between the upper surface of the lower rear bar 600 and the lower end of the rear door B, So that it can smoothly rotate without being in frictional contact with the upper end surface of the lower rear bar 600. At this time, the axial bushing 234 may be omitted.

In addition, the upper rotating shaft 230b may be formed in a substantially 'b' shape, and may have a threaded structure although not shown at a portion of the length of the vertical portion, that is, a certain distance from the upper end.

A rear door shaft hole 236a is formed in the upper end surface of the rear door B at a position where the upper rotation shaft 230b is to be inserted and a shaft guide bracket 236b Is welded or assembled and fixed.

The upper end of the vertical portion of the upper rotation shaft 230b is inserted through a shaft guide bracket 236b in a vertical straight line coinciding with the rear door shaft hole 236a and the spring 236c is fitted in the state, The fastening hole 236d may be screwed onto the thread of the upper rotary shaft 230b or may be welded or press-fitted after the fastening hole 236d is fitted on the upper rotary shaft 236c.

In this state, when the upper end of the upper rotary shaft 230b is pressed, the spring 236c is compressed and the upper rotary shaft 230b is moved downward, so that the upper end of the upper rotary shaft 230b is aligned with the rear door shaft hole 236a.

The upper end of the upper rotary shaft 230b is exposed through the rear door shaft hole 236a while the fastening hole 236d is pushed up due to the elastic returning force of the spring 236c so that the upper end of the rear door B can be rotated So that it can be supported.

When the upper rear bar 400 is not used, the upper rotation bar 230b is rotatably supported on the top cover 700. The upper rotation bar 230b is rotatably supported by the rotation shaft groove YB2 formed on the upper rear bar 400. [ The rotation axis groove YB2 may be formed.

In this case, since one end of the spring 236c is hooked to the upper end of the shaft guide bracket 236b and the other end is hooked to the lower end of the fastening hole 236d, The upper rotation shaft 230b is pulled up by the force of the spring 236c and the upper rotation shaft 230b is pulled up by the force of the spring 236c. B projecting from the upper end face of a certain length.

The upper rotary shaft 230b having such a structure is installed in the lower rear bar 600 due to the absence of the projections 232 in the lower rotary shaft 230a when the upper rotary shaft 230b is turned upside down due to restriction of the opening / closing direction of the rear door B. [ A gap between the upper surface of the rear door B and the lower end of the rear door B can not be maintained.

This is because the lower bushing 230a has no projections 232. Therefore, when the rear door B is turned upside down, a separate bushing 234 acting as a shaft bushing 234 assembled to the lower rotation shaft 230a, (Not shown) is inserted into the upper rotation shaft 230b and then installed on the lower side, the bushing maintains the role of the protrusion 232, so that it does not hinder the opening and closing of the rear door B.

In addition, the rear door B preferably has the structure of the crash dampening material SB of the cabinet door D as described above.

A plurality of fastening bosses 240 projecting from the inner wall surface and integrally extruded are protruded in the rear post 200.

The fixing boss 240 is a means for screwing the top cover 700 and the bottom base 800. Although not shown in the figure, the fixing boss 240 penetrates the top cover 700 and the bottom base 800 in the thickness direction of the top cover 700 and the bottom base 800, And then screwed in the fastening bosses 240, so that they can be securely fixed.

7, a plate fitting groove 250 is formed on a surface of the rear post 200 opposite to the side where the rear door B is installed.

The plate fitting groove 250 is formed by extruding two projecting pieces 252 so as to have a substantially C shape. The side plates S1 and S2 are fitted into the plate fitting groove 250, respectively.

In this case, an assembling hole AS for connecting the side plates S1 and S2 may be further formed in the plate fitting groove 250. [

In addition, a rack frame fixing part 260 is integrally formed around the edge of the same plane with the plate fitting groove 250, and the rack frame fixing part 260 is fixed to the rack frame fixing part 260 by a rack frame (170) are symmetrically installed.

In this case, fasteners 172 may be formed on the upper and lower ends of the rack frame 170 to be screwed on the rack frame fixing parts 260.

On the other hand, the top cover 700 is mounted on the fixing bosses 140 and the fastening bosses 240 provided on the inner upper ends of the front posts 100 and the rear posts 200, It is firmly fixed by screwing.
