Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1 and 2, a height adjusting mechanism based on computer control comprises a base and a supporting plate 1, wherein the base comprises a bottom plate 2, two vertical plates 3 which are parallel to each other are vertically and fixedly arranged on the upper end surface of the bottom plate 2, and guide strips 4 which are vertically arranged are fixedly arranged on the opposite side surfaces of the two vertical plates 3. The horizontal setting of

backup pad

1, 1 both sides of backup pad respectively are fixed and are equipped with a sliding sleeve 5, two sliding sleeve 5 overlaps respectively and establishes on two guide strips 4 and can only be along guide strip 4 longitudinal sliding.

The fixed mount 6 that is equipped with of terminal surface under backup pad 1, mount 6 includes two curb plates 7 that are parallel to each other, fixedly between two curb plate 7 bottoms be equipped with diaphragm 8, the fixed swivel nut 9 that is equipped with on diaphragm 8, install vertical setting and screw rod 10 that can only autogyration on the bottom plate 2, the screw rod 10 cover is established in the swivel nut 9 and with the swivel nut 9 spiro union, fixedly on the screw rod 10 be equipped with first gear 11, some second gear 12 of meshing on the first gear 11, still fixedly on the bottom plate 2 be equipped with be used for driving motor 13 of the rotation of second gear 12, motor 13 is step motor 13, motor 13 is fixed on the bottom plate 2, motor 13 with mount 6 dislocation set.

The base is also fixedly provided with a controller 14, the controller 14 adopts a PLC controller, the vertical plate 3 is fixedly provided with an upper limit switch 15 and a lower limit switch 16 for longitudinally limiting the supporting plate 1, the upper limit switch 15 is positioned above the supporting plate 1, and the lower limit switch 16 is positioned below the supporting plate 1; the motor 13, the upper limit switch 15 and the lower limit switch 16 are respectively electrically connected with the controller 14, and the controller 14 is connected with a USB data line 17 for connecting with a computer.

Four supporting blocks 18 are fixedly arranged on the lower end face of the bottom plate 2. The first gear 11 and the second gear 12 are located below the bottom plate 2. The two sides of the supporting plate 1 are respectively and vertically fixedly provided with a side plate 19, and the side plates 19 on the two sides of the supporting plate 1 are parallel to each other.

This application is when using, earlier places the quick-witted case of computer in backup pad 1, and places the quick-witted case between two riser 3, between two sideboard 19, connects USB data line 17 on computer machine case again, and the installation is used for controlling the procedure of motor 13 corotation, reversal on the computer, this procedure only need can be through controller 14 control motor 13 corotation or reversal can, be not the scope that this application needs the protection. When the computer support is used, a program on a computer sends a command for driving the motor 13 to rotate forwards to the controller 14, the controller 14 sends a command for controlling the motor 13 to rotate forwards, the motor 13 drives the second gear 12 to rotate, and then the first gear 11 is driven to rotate, the first gear 11 drives the screw rod 10 to rotate backwards, because the screw sleeve 9 can only move longitudinally along with the support plate 1, when the screw rod 10 rotates, the height of the screw sleeve 9 can be adjusted, so that the height of the support plate 1 can be adjusted, and further the height of a computer case on the support plate 1 is adjusted, when the screw rod 10 rotates backwards, the support plate 1 moves upwards, and similarly, a program on the computer sends a command for driving the motor 13 to rotate backwards to the controller 14, and the controller 14 sends a command for controlling the motor 13 to rotate backwards, and then drives the screw rod 10 to rotate forwards, and finally the support plate 1 moves downwards. When backup pad 1 rebound touched last limit switch 15, last limit switch 15 transmission signal gave controller 14, and controller 14 control motor 13 stops corotation, and backup pad 1 stops rebound, avoids swivel nut 9 and screw rod 10 to break away from, and is right the utility model discloses play the effect of protection. When the support plate 1 moves downwards and touches the lower limit switch 16, the lower limit switch 16 transmits a signal to the controller 14, the controller 14 controls the motor 13 to stop rotating reversely, and the support plate 1 stops moving downwards.
