The content of utility model
The purpose of this utility model is design a kind of table top lifting and a door opening and closing mechanism, and it is steady that it has lifting, and the switch door moves rational characteristics, and this mechanism can make common table and use, and uses at the bottom of also can being hung in ceiling.
The utility model can be realized by following scheme:
Table top lifting and door opening and closing mechanism include shell, deck plate, stand, elevating mechanism and door opening and closing mechanism, and deck plate is located at the shell top, deck plate central authorities have hatchway, be provided with stand before and after in the shell, elevating mechanism and door opening and closing mechanism are located between the interior stand of shell, it is characterized in that:
Described elevating mechanism includes an elevating bracket, vertical shaft tooth bar and is installed in the drive unit of elevating bracket inside, this drive unit has two ends by the driving shaft of bearing fixing in elevating bracket, lifter wheel with the engagement of vertical shaft tooth bar is installed on the driving shaft, travelling gear also is installed on the driving shaft, the motor that is installed in the elevating bracket is connected with a joggle by power gear and travelling gear, and this drive unit makes rising, the decline of the forward and reverse rotating drive elevating bracket of motor;
Elevating bracket be provided with can be inserted in the vertical shaft tooth bar axle sleeve to prevent the canting of the elevating bracket left and right sides, an equipment bearing support is installed in the top of elevating bracket, and support plate is housed on the bearing support;
Described door opening and closing mechanism is by fulcrum shaft 4 (left and right each 2) switch door arms to be installed at stand the right and left, there are left and right two switch door-plates to connect and compose left-handed opening door and right switch door with front and back two switch doors arm end on left and right limit respectively, left and right two pull rod shaft that are positioned at the elevating bracket below are arranged, the other end of front and back two switch doors arm on left and right limit and the two ends of pull rod shaft flexibly connect by pull bar, and door opening and closing mechanism is provided with opens spring.
Pull bar can be changed into soft chain or rope, so also can not establish pull rod shaft, switch door arm is connected with elevating bracket by soft chain or rope, have identical effect according to above-mentioned principle.
Operation principle is: the rotation of motor makes whole elevating bracket rise or descend along tooth bar simultaneously together with motor by drive unit.
When elevating bracket was positioned at the top, the switch door was in open mode, starts motor elevating bracket is descended, during to certain position, pull bar or tightrope (chain) Drawing switch door arm is along with the slowly decline of elevating bracket, left and right two switch doors are slowly drawn close to close and are closed, and motor quits work.
Otherwise, when rising, at first loosened pull bar or tightrope (chain) when elevating bracket is positioned at lower, switch door arm is opened under the pulling force of spring, when the switch door reached maximum position, elevating bracket no longer contacted with pull bar or tightrope (chain), rose to table position and inherit.
The utlity model has rational in infrastructurely, lifting is steady, and characteristics such as switch door graceful movements can be made common table and collection equipment is installed is used, and also can hang upside down at the bottom of ceiling and use.
Example with accompanying drawing is further described the utility model below:
