As shown in FIG. 5, the coupling pins 60 protrude rearwards from both side portions 56 of the lower rear side of the front case 51, respectively. Coupling pin 60 is in the shape of a square bar having a predetermined length, a pair of reinforcing jaw 61 arranged side by side in the longitudinal direction on the top surface is protruded. In addition, a locking end 62 having an inverted triangular cross-sectional structure is formed at the front end lower surface of the coupling pin 60.

The pair of reinforcing jaw 61 is protruded to a predetermined height at both sides of the upper surface of the coupling pin 60 is formed extending in the longitudinal direction. The pair of reinforcing jaw 61 is spaced apart from each other to have a predetermined interval (t1).

On the other hand, as shown in Figure 6, the receiving hole 70 of the rear case 53 is formed to protrude downward on both side portions 54 of the lower front of the rear case 53. The storage hole 70 is rectangular in shape and has a predetermined length so that the front and rear sides thereof are opened. A pair of locking jaws 72 are formed at both sides of the bottom portion 71 of the storage hole 70. The pair of locking jaws 72 has an inclined surface 73 having a predetermined inclination so that the upper surface height thereof becomes higher toward the rear. The rear end is formed higher than the front end. Therefore, as shown in FIG. 7, when the coupling pin 60 of the front case 51 is inserted, the pair of locking jaws 72 when the locking end 62 of the coupling pin 60 moves backwards. It slides up and rises along the inclined surface 73 of the upper portion, and is restored to its original position in the state where the locking jaw 72 is fully inserted up to the end point, so that the locking end 62 ends the pair of locking jaws 72. Will be caught.

As shown in FIG. 6, the front end of the ceiling 75 of the storage hole 70 is cut in a stepped shape to form a locking groove 74. A rectangular fixing hole 76 penetrates the ceiling 75 of the storage hole 70 at a rear of the predetermined distance behind the locking groove 74.

On the other hand, as shown in Figure 7, when the coupling pin 60 is coupled to the locking jaw 72 of the receiving hole 70, the leading end portion of the coupling pin 60, that is, the reference numeral portion 62 By pushing up in the direction of the arrow of 90, it can be easily separated from the storage hole 70 without using a tool such as a driver. Therefore, the rear case 53 may be separated from the front case 51 even when the user uses the monitor 50. In order to prevent this, in the present invention, a snap pin 80 as shown in FIG. 6 is provided. 6 to 8 will be described in more detail with the snap pin (80).

As shown in FIG. 6, the snap pin 80 has an upper body 81 and a lower body 83 that are integrated with a gap therebetween, and a connecting portion 82 that integrally connects the upper and lower bodies 81 and 83. It consists of

The upper body 81 is a polygonal plate and the front end thereof is connected to the connecting portion 82, and the projection 86 protruding in the downward direction is formed on the bottom of the rear end thereof.

In addition, the lower body 83 is the front end portion is connected to the connecting portion 82 and is integrated with a gap in the upper body 81, the first end and the second member in the shape of 'Ｖ' toward the rear toward the rear end (84,85) are installed. The first and second members 84 and 85 are made of a material having elasticity and elastically displaceable in the direction of the arrow 87. The projections 86 protrude downward from the bottoms of the ends of the first and second members 84 and 85, respectively. In addition, the width t2 of the lower body 83 is formed to be smaller than the interval t1 of the pair of reinforcing jaw 61 of the coupling pin 60.

Therefore, as shown in FIG. 8, when the first and second members 84 and 85 of the lower body 83 are aligned with each other along the arrow direction 87, the coupling pins 60 are in a state like a dotted line. It is housed between a pair of reinforcing jaw (61). As can be seen from Figures 7 and 8, it enables the vertical displacement of the coupling pin (60). Therefore, as can be seen in Figure 7, the engaging pin 60 is pushed up in the direction of the arrow 90 so that the locking end 62 of the front end thereof out of the locking jaw 72 and then from the receiving hole 70 I can pull it out. Accordingly, the front case 51 and the rear case 53 can be separated. On the contrary, as shown in FIG. 8, when the first and second members 84 and 85 are spread along the arrow direction 87. Since the interval t2 of the first and second members 84 and 85 becomes larger than the interval t1 of the pair of reinforcing jaws 61, the pair of reinforcing jaws 61 is not stored between the pair of reinforcing jaws 61. The reinforcing jaw 61 is located above. Thus, the first and second members are in close contact with the upper surface of the reinforcing jaw 61 of the locking pin 60, so that the coupling pin 60 is not displaced upward in the state shown in FIG. Thus, the front pin 51 and the rear case 53 are not separated from each other by acting as a wedge that prevents the coupling pin 60 from coming out from the state inserted in the storage hole 70.

On the other hand, in the snap pin 80, the upper and lower bodies 83 are integrated with each other by the connecting portion 82 having a predetermined height to form a predetermined space therebetween. Thus, when the snap pin 80 is coupled to the storage hole 70, as shown in Figure 7, through the space between the upper body 81 and the lower body 83, the ceiling portion of the storage hole 70 ( 75). At this time, the projection 86 of the upper body 81 is elastically displaced upwards, and then slides backward along the upper surface of the ceiling portion 75 of the storage hole 70 and then restored from the fixing hole 76 to fix the fixing hole 76. The snap pin 80 is coupled to the ceiling 75 of the accommodation hole 70 by being fitted in the).

Hereinafter, with reference to the accompanying drawings will be described in more detail the operation of the monitor case according to an embodiment of the present invention.

As shown in FIG. 3, when the user couples the rear case 53 to the front case 51, first, as shown in FIG. 6, the snap pin 80 is inserted into the storage hole 70 of the rear case 53. To combine. That is, the first and second members 84 and 85 of the snap pin 80 are aligned in the direction of the fixing hole 76 formed in the ceiling 75 of the storage hole 70, and then an external force is applied to the snap pin 80. When pushed to the snap pin 80 is pushed by the external force at this time, the projection 86 of the upper body 81 slides backward along the upper surface of the ceiling portion 75 of the storage hole 70 fixed hole 76 ) Thus, the snap pin 80 is fitted into the ceiling 75 of the storage hole 70 is coupled.

When the snap pin 80 is fixed to the storage hole 70, the first and second members are in a state of opening as shown in FIG.

After the snap pin 80 is coupled to the storage hole 70, the user aligns the front case 51 with the coupling position with the rear case 53. After collecting the first and second members 84 and 85 of the snap pin 80 (see the dotted line in FIG. 8), the front case 51 is pushed backward to move the coupling pin 60 to the storage hole of the rear case 53. Insert in 70. When the coupling pin 60 begins to be inserted into the storage hole 70, as can be seen in Figure 7, the locking end 62 of the tip of the coupling pin 6 is a pair of locking jaws of the storage hole 70 72 is elastically displaced upward while moving along the inclined surface 73 of the upper portion, the state is moved to the maximum, that is, restored from the end of the locking jaw 72 as shown in Figure 7 is caught on the locking jaw (72). Accordingly, the locking end 62 of the coupling pin 60 is fixed to the pair of locking jaws 72 so that the lower portion of the front case 51 and the rear case 53 are integrally coupled to each other. At this time, the snap pin (80) is the first and second members (84, 85) in close contact with the upper surface of the reinforcing jaw 61 of the coupling pin (60) to prevent the coupling pin (60) from rising and the coupling pin (60). ) Does not escape from the receiving hole 70 by an external force, thereby acting as a wedge for the coupling pin (60). On the other hand, the front end portion of the coupling pin 60, that is, the locking end 62 penetrates through the storage hole 70 and is exposed to the rear of the rear case 53. Accordingly, the user can first and second members of the snap pin 80. In the collected state (see the dotted line in Fig. 8) by pushing the locking end 62 in the direction of the arrow 90 using a tool such as a screwdriver to release the locking on the locking jaw 72 and the front case 51 and The rear case 53 can be disassembled.

After the lower portions of the front and rear cases 51 and 53 are coupled, the upper portions of the front and rear cases 51 and 53 are integrally coupled to each other by penetrating the fastening screws.

In the case of separating the lower portions of the front and rear cases 51 and 53, first, the first and second members 84 and 85 of the snap pins 80 exposed to the outside of the bottom surface of the rear case 53 are first released. Coincides with the arrow direction 87. At this time, since the width t2 of the lower body 83 of the snap pin 80 is narrower than the interval t1 of the reinforcing jaw 61 of the coupling pin 60, the snap pin 80 is the reinforcing jaw 61. ) Is stored between (see dashed line in FIG. 8). Therefore, as the space in which the coupling pin 60 is moved upward is formed, the coupling pin 60 can be lifted upward. It moves a predetermined distance to the next upper part. Next, as shown in FIG. 7, the user pushes the tip portion of the coupling pin 60 in the direction of the arrow 90 so that the locking end 62 of the coupling pin 60 is locked by the storage hole 70. To be released from

After the coupling pin 60 is released from the storage hole 70, the front case 51 and the rear case 53 may be separated by moving the front case 51 a predetermined distance forward.

As described above, after separating one side, the other side can be separated by the same process as described above.

As described above, the case of the monitor according to the present invention adopts an interference fit structure according to the elastic displacement of the coupling piece and a wedge coupling method of the snap method, so that assembly and disassembly are possible without tools such as a driver, which is very convenient to assemble and release. Has the advantage. Therefore, the time required for assembly disassembly can be greatly shortened. In addition, there is an advantage in that the front case and the rear case are prevented from being arbitrarily separated by providing a snap pin to prevent the case lower coupling structure of the monitor from being easily separated by an impact.
