Fig. 2 is the structure left view of the embodiment of the invention.
Fig. 3 is the structure vertical view of the embodiment of the invention.
Among the figure: 1 is feet; 2 is gripper shoe; 3 are the rotation swivel nut; 4 is screw rod; 5 is connecting rod; 6 is the desktop base; 8 is the uplink and downlink starting switch; 9 is back-up block; 31 is worm gear; 32 is worm screw; 33 is drive motors; 34 is the drive motors control box; 71 is descending limit switch; 72 is up limit switch.
The specific embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, embodiment cited below particularly, and cooperate appended graphic being described in detail below.
With reference to figure 1, a kind of desktop lowering or hoisting gear, comprise the gripper shoe 2 that supports by feet 1, it is characterized in that: described gripper shoe 2 tops are provided with rotation swivel nut 3, described rotation swivel nut 3 two ends are equipped with the opposite screw rod of thread rotary orientation 4 respectively, the outboard end of described screw rod 4 and connecting rod 5 one ends are hinged, and connecting rod 5 the other end and a desktop base 6 are hinged, and described desktop base 6 tops are connected with desktop A.
Above-mentioned rotation swivel nut 3 periphery walls middle part is provided with the worm gear 31 coaxial with rotating swivel nut 3, and a described worm gear 31 and a worm screw 32 are connected, and described worm screw 32 is connected with drive motors 33 on being located at gripper shoe 2.
Be positioned at desktop base 6 belows on the above-mentioned gripper shoe 2 and be provided with descending limit switch 71; Described gripper shoe 2 is provided with up limit switch 72, and described up limit switch 72 is positioned on screw rod 4 running orbits and is positioned at desktop base 6 belows.
Above-mentioned drive motors 33 is connected with a drive motors control box 34, and described up limit switch 72 is connected with drive motors control box 34 with the signal output part of descending limit switch 71; Described drive motors control box 34 is connected with uplink and downlink starting switch 8.
Be provided with back-up block 9 between above-mentioned gripper shoe 2 and the desktop A.
Desktop uplink and downlink starting switch is controlled the forward and reverse of motor respectively, and desktop rises when just changeing, and desktop descends during counter-rotating.When desktop rises to the extreme higher position (connecting rod is in vertical state), can trigger the up limit switch that is arranged at gripper shoe, make desktop stop to rise.(desktop drops to the back-up block upper end) can trigger the descending limit switch that is arranged at gripper shoe when desktop drops to extreme lower position, makes desktop stop to descend.
In one embodiment of the invention, when motor rotated, the rotation swivel nut that is had positive and negative internal thread by the motor worm gear drives rotated, and carried out rectilinear motion thereby drive screw rod; When the rotation swivel nut rotates, with drivening rod in opposite directions or reverse motions toward both sides, with the gradient that changes connecting rod to reach the effect of desktop lifting.
When motor just changeed, the screw rod both sides prolonged, and promoted connecting rod and toward vertical moving desktop were raise.When motor reversed, screw rod shortened toward middle, and the pulling connecting rod reduces desktop toward laterally moving.
In another embodiment of the present invention, motor can be removed, change a mechanical worm gear pole into, adopt hand mode desktop to be raise or reduction.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
