The following briefly describes the state of use of the multipurpose laboratory bench 100 formed as described above.

When the multi-purpose laboratory table 100 according to the present invention is used for general education and conference use, the laboratory wet equipment (L) and the monitor (M) are arranged to be used within the first chamber 130 and the second chamber 140. In addition, when the computer (C) is used during computer training and meetings, only the monitor (M) is used by elevating the top plate 110, and during the lab training, the lab humidity device (L) and the monitor (M) are elevated by Will be used. Therefore, the multipurpose bench 100 according to the present invention can satisfy the needs of various consumers.

Hereinafter, the state in which the laboratory humid apparatus L and the monitor M built in the first chamber 130 and the second chamber 140 are raised and lowered will be briefly described.

First, in order to elevate and use the laboratory humid apparatus L, first, the lock rod 270 holding the first swing door 252 is released through the through hole 208 formed in the front finish plate 206. As anyone can see, the lock rod 270 of the lodge clamp 268 is terminated in the usual way. When the lock rod 270 of the latch stop 268 is released in this way, the adjustment rod 276 compressed in the adjustment cylinder 274 is raised, and the first turning door ( The 252 protrudes to the upper portion of the first seating hole 252.

When the first swing door 252 protrudes from the first seating hole 252, the first swing switch 226 is operated to apply power to the laboratory humid apparatus lifting device 200, and then the first swing door 252. The 252 is pivoted to the rear side of the upper plate 110 and then inserted into the first chamber 130. The guide rod 260 connected to the first pivot door 252 and the first hinge 262 is a guide rail ( The first pivot door 252 is inserted into the first chamber 130 while descending along 258. As described above, when the first turning door 252 is inserted into the first chamber 130, the first turning door 252 is in contact with the third limit switch 266 of the guide bar 260, and the guide bar is connected to the third limit switch 266. When the 160 is in contact, the first controller 246 operates the first driving motor 234 to lift and move the mobile stage 220 on which the laboratory humid apparatus L is placed.

When the first drive motor 234 is operated, the first drive motor 234 rotates the first winding disc 236, and the first winding disc 236 moves the first towing wire 240 to the first drive motor. 234, the first fixing block 242 fixed to the first towing wire 240 and the moving stage 220 is raised, and as a result, the moving stage 220 is the first frame 210. While rising along the vertical guide bar 212 formed in the laboratory humidifier (L) to be drawn out to the top of the upper plate (110). On the other hand, when the rising stage 220 is moved to the first contact bracket 224 mounted on the movable stage 220 to the first limit switch 214, the first controller 246 is the first drive motor 234 Stops operation.

On the contrary, in order to embed the laboratory humidifier L into the first chamber 130, the first swing door 252 inserted into the first chamber 130 is first drawn out of the first chamber 130. The guide bar 260 in contact with the three limit switch 216 is spaced apart from the third limit switch 216. When the guide bar 260 is spaced apart from the third limit switch 216, the first controller 246 rotates the first driving motor 234 in reverse to lower the moving stage 220. When the first contact bracket 224 of the descending moving stage 220 contacts the second limit switch 216, the first controller 246 stops the operation of the first driving motor 234. At this time, the buffer rod 282 of the buffer cylinder 280 is gradually inserted into the buffer cylinder 280 while absorbing the impact of the moving stage 220 to descend.

When the laboratory humidity device L is completely lowered into the first chamber 130, the first swing door 252 is seated in the first seating hole 254, and the first swing door 252 is seated. When the adjustment rod 276 is inserted into the adjustment cylinder 274, and the first swing door 252 is seated in the first seating hole 254, the lock rod 276 of the lodge clamp 268 is a locking hole ( 272) is pressed to fix the first swing door 252.

On the other hand, in order to raise and use the monitor M, the second operation switch 318 is operated. When the second operation switch 318 is operated, the second controller 344 operates the second drive motor 334. When the second drive motor 334 is operated, the second drive motor 334 rotates the second winding disc 336, and the second winding disc 336 drives the second towing wire 340 to the first drive motor. 334, the second fixing block 342 fixed to the second towing wire 340 and the moving plate 320 is raised, and as a result, the moving plate having the monitor M mounted thereon ( 320 is raised. At this time, when the movable plate 320 is raised, the third contact bracket 364 is spaced apart from the pressurized operating bracket 366. When the third contact bracket 364 is spaced apart from the operating bracket 366, The actuating bracket 366 and the actuating shaft 360 are raised by the compressed spring 368, which is compressed, and the actuating shaft 360, which rises, pushes the second pivot door 352 to the second pivot door 352. ) Open. As such, when the second swing door 352 is opened, the monitor M is drawn out to the upper portion of the upper plate 110. On the other hand, when the second contact bracket 324 of the moving plate 320 is in contact with the fourth limit switch 314, the second controller 344 stops the operation of the second drive motor 334.

On the contrary, in order to embed the monitor M into the second chamber 140, the second operation switch 318 is operated again. When the monitor M operates the second operation switch 318 while the upper plate 110 is pulled out, the second controller 344 rotates the second driving motor 334 in reverse to move the movement plate 320. Descend. When the second contact bracket 324 of the descending moving plate 320 contacts the fifth limit switch 216, the second controller 344 stops the operation of the second driving motor 334. At this time, the descending third contact bracket 362 formed on the moving plate 320 presses the actuating bracket 366. As a result, the actuating shaft 360 pushing the second swinging door 352 is lowered. The second pivot door 352 is seated in the second seating hole 354.

Meanwhile, in order to use a notebook (not shown) according to a user, the cover door 378 is rotated toward the system box 376 and used.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims. You will understand.
