Property.
In original state, the cover plate 2 is in the upper end position of the cover plate chute 5, the bottom of the rack 22 with
The gear 73 is intermeshed, and the securing rod 67 extend into the cover plate chute 5 due to the top pressure of the compression spring 65
In；
When needing to close the loading chute 3, motor 71 operates up and down for control so that upper and lower motor 71 supplies power to gear
73, drive the cover plate 2 to move downward by gear 73, the pressure inclined-plane 21 at the left side bottom of cover plate 2 with it is described by
When pressure inclined-plane 68 abuts against, upper and lower motor 71 remains in operation, and the inclined-plane 21 that then presses overcomes the pressure on top surface of the compression spring 65,
And make it that the securing rod 67 is retracted into the perforation 70 to the left, i.e., external splines bar 64 is retracted into inner spline sleeve 63 to the left
In, now, the right side of the securing rod 67 and the left side of the cover plate 2 offset, and the cover plate 2 continues to move downward, directly
When the groove bottom of bottom face and the cover plate chute 5 to the cover plate 2 abuts against, the motor 71 up and down is controlled to stop fortune
Turn, now, the top of the rack 22 is intermeshed with the gear 73, the top of the top end face of the cover plate 2 and the casing 1
End face, the securing rod 67 is relative with the lock slots 6, and the securing rod 67 is due to the top by the compression spring 65
Pressure and to stretch out the perforation 70 outer and extend into the lock slots 6, the securing rod 67 extend into the lock slots 6 with
Afterwards, the bottom end of the securing rod 67 mutually abuts with the lower end wall of the lock slots 6, now, the cover plate 2 and the cover plate
Chute 5 is cooperated and the cover plate 2 is locked in the cover plate chute 5, and the loading chute 3 is closed.
When needing to open the loading chute 3, first control left and right motor 61 to operate, power and band are provided by left and right motor 61
The dynamic securing rod 67 rotates 180 degree, and causes the compression inclined-plane 68 down in order to mutually being slided with the guiding incline 69
It is connected, now, motor 71 inverts up and down for control so that upper and lower motor 71 supplies power to gear 73, is driven by gear 73
The cover plate 2 moves upwards, the guiding incline 69 at the left-hand notch of the lower end wall of lock slots 6 and the phase of compression inclined-plane 68
During abutting, upper and lower motor 71 remains in operation, and then guiding incline 69 overcomes the pressure on top surface of the compression spring 65, and causes the lock
Fixed pole 67 is retracted into the perforation 70 to the left, i.e., external splines bar 64 is retracted into inner spline sleeve 63 to the left, now, the lock
The right side of fixed pole 67 and the left side of the cover plate 2 offset, and the cover plate 2 continues up, until a left side for the cover plate 2
End face disengaging is abutted against with the right side of securing rod 67 and the bottom of the rack 22 is intermeshed with the gear 73 again
When, now, motor 71 shuts down up and down for control, and the loading chute 3 is in open mode and tieed up in order to the installation of computer fittings
Shield, and now the securing rod 67 is stretched out outside the perforation 70 and extend into due to the pressure on top surface by the compression spring 65
In the cover plate chute 5, finally control left and right motor 61 to operate, provide power by left and right motor 61 and drive the securing rod 67
Rotate 180 degree again and cause the compression inclined-plane 68 upward in order to be mutually slidably connected with the pressure inclined-plane 21,
In order to be again switched off the loading chute 3.
The beneficial effects of the invention are as follows：
1. by controlling motor operating up and down to supply power to gear, cover plate is driven to move downward by gear, when cover plate left side
When pressure inclined-plane at bottom abuts against with compression inclined-plane, pressure inclined-plane overcomes the pressure on top surface of compression spring, and causes securing rod
It is retracted into the left in perforation, now, the right side of securing rod and the left side of cover plate offset, and cover plate continues to move downward, until
When the bottom face of cover plate and the groove bottom of cover plate chute abut against, control up and down motor shut down, now, the top of rack with
Gear is intermeshed, and the top end face of cover plate flushes with the top end face of casing, securing rod due to the pressure on top surface by compression spring and
It is outer and extend into lock slots to stretch out perforation, after securing rod is extend into lock slots, the bottom end of securing rod and lock slots
Lower end wall mutually abuts, and cover plate is cooperated with cover plate chute and cover plate is locked in cover plate chute, so as to which loading chute be closed
Close, in order to protect the computer fittings in loading chute without damage, cover plate realizes automatic close.
2. by controlling left and right motor to operate, provide power by left and right motor and drive securing rod degrees of rotation, and cause by
Inclined-plane is pressed down in order to be mutually slidably connected with guiding incline, then controls motor reversal up and down so that upper and lower motor carries
Cover plate is driven to move upwards for power, when guiding incline abuts against with compression inclined-plane, upper and lower motor remains in operation, then guiding incline
Overcome the pressure on top surface of compression spring, and make it that securing rod is retracted into perforation to the left, now, the right side of securing rod and cover plate
Left side offsets, and cover plate continues up, and is abutted against until the left side of cover plate departs from securing rod right side and rack
When bottom is intermeshed with gear again, now, motor shuts down up and down for control, and loading chute is in open mode, so as to side
Just the computer fittings in loading chute is safeguarded.
3. the overall structure of the present invention is simple, cost is cheap, and cover plate easy installation and removal is quick, is adapted to promote the use of, energy
The up and down motion of enough automatic traction cover plates is to realize the automatic closing of loading chute with opening, and when cover plate damage needs to change
Cover plate can be pulled out to cover plate chute, so as to cause the top of rack mutually to be nibbled with gear new cover plate insertion cover plate chute upwards
Close.
