Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the platform comprises a platform 1, a cabinet 101, a supporting platform 2, a sliding cover 3, a locking piece 301, a display screen 4, a drawer 5, a projector 6, an elevating platform 7, a case 8, a top plate 801, a bottom plate 802, a side cover plate 803, a rack 804, a power supply 805, a memory bar 806, a display card 807, a hard disk 808, a CPU809, an expansion link 9, a fan 10, a hasp 1001, a fixing block 1002, an air cylinder 11, a carrying table 12, an air pressure suction cup 13, an air pump 14, a storage battery 15, a universal wheel 16, a rubber pad 17 and an air hole 18.
The first embodiment is substantially as shown in figures 1 to 4 of the accompanying drawings: a computer practice comprehensive teaching device comprises a platform 1, wherein a support platform 2 and a sliding cover 3 are arranged on the upper part of the platform 1, the sliding cover 3 is connected to the upper part of the platform 1 in a sliding manner through a sliding rail, a cabinet lock 301 is arranged at the upper end of the sliding cover 3, the sliding cover 3 can be locked on the platform 1, and the support platform 2 is used for installing a display screen, a mouse and a keyboard; a cabinet 101 is arranged below the supporting platform 2 and the sliding cover 3, a drawer 5 is arranged on the side surface of the cabinet 101, and a projector 6 is arranged in the drawer 5; a cylinder 11 is fixed on a bolt in the cabinet 101, a lifting table 7 is fixed on an output shaft of the cylinder 11 through a bolt, a bearing table 12 is rotatably connected on the lifting table 7, a bolt is fixedly installed on the bearing table 12, a pin hole matched with the bolt is formed in the lifting table 7, a case 8 is placed on the bearing table, the case 8 comprises a top plate 801, a bottom plate 802, a side cover plate 803, a rack 804 and internal elements located inside the case 8, the bottom plate 802 is slidably connected with the side cover plate 803, a rack 804 is fixed on the bottom plate 802 through a bolt, a power supply 805 is further installed on the bottom plate 802, a main plate is fixedly connected on the rack 804, a memory bar 806 is installed on the main plate, a display card 807, a hard disk 808 and a CPU809, an expansion link 9 is slidably installed around the CPU809, a fan 10 is fixedly connected on the other end of the expansion link 9, a hasp 1001 is.
The specific implementation process is as follows: during teaching, the computer display screen 4 is opened, the locking piece 3 is opened, the sliding cover 2 is slid, then the cylinder 12 is opened, the cylinder 12 lifts the lifting platform 7, and the case 8 is lifted; at this time, the bottom plate 802 is pulled, the bottom plate 802 slides out of the case 8, and the internal structure of the case 8 can be observed; then, the buckle 1001 is opened, the fan 10 slides to one side of the CPU809, and the CPU809 can be displayed; meanwhile, the bearing table is rotated to show students at different angles, the drawer 5 can be pulled open, the projector 6 is opened, and the projector 6 is used for assisting teaching.
Example two:
the second embodiment is a further optimization of the first embodiment, which is basically as shown in fig. 5: the difference lies in that: the universal wheels 16 are installed at the bottom of the cabinet 101, the braking devices are fixedly installed on the universal wheels 16, rubber pads 17 are adhered to corners of the platform 1, and the storage battery 15 is installed in the cabinet 101.
The specific implementation process differs from the first embodiment as follows: when needs remove whole device, open arresting gear on the universal wheel 16 like the yuchen AB type universal wheel brake among the prior art for the device is whole to be removed, thereby battery 15 can supply power to quick-witted case 8 and display screen 4 and can be used for the outdoor teaching with this device, and all bond all around of 1 platform corner of podium has rubber pad 17, the dynamics that 1 striking of podium can be cushioned at the in-process rubber pad 17 that removes, can protect podium 1 and the inside quick-witted case 8 of rack 101.
Example three:
the third embodiment is a further optimization of the first embodiment, and is basically as shown in the accompanying fig. 6: the outer of the fan 10 in the case 8 is provided with air holes 18, and the air outlet of the air pump 14 is communicated with the case through an air pipe. The air inlet of the air pump 14 is communicated with the air pressure suction cup 13.
The specific implementation process is as follows:
when the air pump 14 reduces the pressure of the air pressure suction cup 13, the air is transmitted to the fan 10 in the case 8 through the air pipe, the air flows through the air holes 18, the blades of the fan 10 are blown to rotate, and further, the CPU809 is cooled, and because the air holes are formed outside the case, the air direction fan generated by the fan blows all around, the heat dissipation effect of the fan 10 is enhanced, when the internal structure of the case is displayed, the case is in an open state, the dust is easily deposited in the case, and the dust deposited in the case can be blown away in the process of blowing all around by the fan, so that the effect of cleaning the internal environment of the case is achieved.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
