Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
One, structure composition:
The specific structure that the device of the invention uses: as shown in Figure 1:
Hinged one rectangle support that can be rotated around two coaxial hinges (the first articulated position 4) on pedestal 6；Even
A driving wheel 5 is coaxially fixed in the shaft middle position for connecing two the first articulated positions；In addition a motor is fixed on the base
7, no-slip drive is carried out by friction pulley (or belt) between this motor rotating wheel and driving wheel.
With two the first articulated position same distance positions among two vertical bars of rectangle support, there is the shape of falling a Π bracket
It is linked together by two coaxial hinges (the second articulated position 3), two tops of the shape of falling Π bracket pass through two hinges (the
Three articulated positions 2) it is hinged with ceiling 1.
In addition, as shown in Fig. 2, two vertical bars of the shape of falling Π bracket are processed into special bent angle shape strut；Two bent angle shapes
To the vertical range between two the second articulated position connecting rods, the cross tube equal to rectangle support is cut with scissors to second at the bent angle center of strut
Connect the distance between the connecting rod of position.
Two, method and effect
Due to driving wheel in the present invention and two same shafts of the first articulated position, thus when motor passes through friction pulley (or skin
Band) when driving rectangle support rotation, the shape of falling Π bracket rotates under rectangle support drive, thus passes through two hinges (third hinge
Connect position) just control ceiling height；In Fig. 2, when the cross tube of rectangle support is close to two bent angle shape branch of the shape of falling Π bracket
When the bent angle center of bar, ceiling after promotion under the effect of gravity can self-locking fixation, as shown in Figure 3.
If making driving motor using the stepper motor with electromagnetic brake fixed rotating shaft or synchronous motor, compiled with computer
The rotation of process control motor just can control motor and mechanical device of the invention and fix in any rotational angle；Pass through optimization again
The radius ratio for selecting driving wheel and motor rotating wheel can theoretically promote the ceiling of any quality to arbitrary height.
In ceiling back and forth or left and right, the special mechanical device of the location means present invention, can promote reliable and stablely ceiling and arrive
Any position；By increasing output power of motor or increasing the quantity of mechanical device of the present invention, can be promoted in a certain range
The ceiling of any quality is to needing highly.
Pass through the mechanical dimension of each component part of the special mechanical device of the optimization design present invention, so that it may be promoted and be appointed
Arbitrary height of the ceiling for quality of anticipating to needs.As shown in Figure 4 again with a cross bar transmission wheel rim and rectangle support into one
Step is fixed together, and fixed intensity between driving wheel and shaft can be enhanced and reduce the torsion shearing stress between driving wheel and shaft.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention.It is all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
