Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of hanging cabinets, in particular to an electric lifting type hanging cabinet.
[ background of the invention ]
Electric lift type wall cabinet among the prior art includes the open outer cabinet in bottom and locates the inside interior cabinet of outer cabinet, be equipped with elevating system between outer cabinet and the interior cabinet, the cabinet descends in the elevating system drive in order to show outside the cabinet or drive the interior cabinet and rise in order to accomodate outside the cabinet inside, elevating system includes a motor and a transmission lead screw of being connected with motor drive, be equipped with the drive nut with interior cabinet fixed connection on the transmission lead screw, the transmission lead screw is located the centre of interior cabinet, the left and right sides of transmission lead screw is furnished with ball slide rail or linear guide in order to be used for the direction and bear the hypsokinesis component of interior cabinet, connect fixedly through the connecting rod between two ball slide rails or the linear guide, the connecting rod is fixed with drive nut, interior cabinet is directly hung on the connecting rod.
When the unbalance loading of the inner cabinet is increased, the horizontal constraint of the transmission screw rod on the connecting rod is limited, and the ball sliding rails or the linear guide rails on the two sides are free pairs, so that the inner cabinet is easy to incline; in addition, when the tightness of the ball slide rail or the linear guide rail is inconsistent or impurities exist, the inner cabinet also has a deflection phenomenon, so that the inner cabinet is easy to shake, shake left and right and the like when being lifted, and the inner cabinet can be blocked when the deflection is serious, so that the inner cabinet cannot be lifted normally.
In addition, in order to make things convenient for the user to get and put article in the interior cabinet, need guarantee that the interior cabinet descends the back that targets in place, interior cabinet is whole to be exposed, so, the stroke of interior cabinet is great, in order to reduce the stroke of interior cabinet, a wall cabinet turns over a door mechanism is disclosed among the prior art, it fixes on outer cabinet lateral wall inner wall to turn over a door mechanism, the front side of outer cabinet is equipped with uncovered, fix fixed door and the open-ended flap door that sets up of correspondence in uncovered top, drive flap door mechanism drives the parallel upturning of flap door and opens uncovered when interior cabinet descends, namely, the reverse relative motion of flap door and interior cabinet, the top of interior cabinet only need move to open top this moment can, the stroke of interior cabinet has been reduced from this, the time that the interior cabinet was. However, the door-turning mechanism in the prior art includes a first connecting rod and a second connecting rod, one end of the second connecting rod is fixed on the inner wall of the side wall of the outer cabinet, the middle of the first connecting rod is hinged to the other end of the second connecting rod, one end of the first connecting rod is hinged to the door-turning, the other end of the first connecting rod is a free end matched with the wing plate, and when the wing plate drives the free end of the first connecting rod to move downwards, the first connecting rod and the hinged end of the door-turning drive the door-turning to move upwards and outwards. From this can know, the current upturning height that turns over the door is controlled in the length of first link, when needs increase the upturning height that turns over the door, needs increase the length of first link, because the degree of depth of outer cabinet is limited, first link can not infinitely prolong, consequently adopts current door mechanism that turns over to lead to the maximum height that turns over the door and can't satisfy user's demand, and then leads to what open top can not set up too high, can't further reduce the down stroke of interior cabinet promptly.
