Description
Technical field
The utility model belongs to the lowering or hoisting gear manufacturing technology field of multimedia desktop LCDs, particularly a kind of liquid crystal lifter.
Background technology
At commercial field, adopt lifter that LCDs is hidden in below the desktop, be able to extensive use.Such liquid crystal lifter upper cover plate is provided with opening, and opening part is a door closure, and upper cover plate and desktop maintain an equal level.During use, open door closure by door operating gear, and with the past user mode that rises to of LCDs; After finishing using, LCDs is dropped under the desktop, and close door closure, LCDs is hidden under the desktop, do not account for any space of desktop, do not influence the normal use of desktop by door operating gear.Therefore, it has advantage easy to use.But also there is weak point in the structure of liquid crystal lifter at present.The upper cover plate of liquid crystal lifter is provided with opening, and this opening and door closure adapt, and an edge of opening is the chamfering shape, and door closure moves along this chamfering and reaches the keying purpose.But because there is chamfering in this edge, cause the making required precision height of liquid crystal lifter, and when door closure is closed, as be subjected to pressed by external force, because the pressure that it bore is little, door closure can stir, sealing is poor, not only influence the normal use of desktop, and influence the LCDs that is hidden under the desktop, use dangerous.
Summary of the invention
The utility model discloses a kind of liquid crystal lifter, the upper cover plate opening edge that has solved the available liquid crystal lifter is made the required precision height along existing chamfering to cause, and the technical problem of sealing difference.
The technical solution of the utility model is as follows: the liquid crystal lifter comprises: casing, be embedded under the desktop, and top panel and desktop maintain an equal level, but top panel is provided with the door closure of opening and closing;
The door closure headstock gear is located in the casing, drives door closure and opens or close;
Display screen lifting gear, be located in the casing, comprise upper and lower sprocket wheel and driving chain, lowering or hoisting gear drives display screen and rises or descend, door closure links to each other with the door closure headstock gear by the hinge moving plate, the biside plate that casing is relative is provided with the opening guide groove, and the opening guide groove inserts the door-hinge that links to each other with the hinge moving plate, and the movement locus that door closure opens and closes is identical at the sliding trace of opening guide groove with door-hinge.
Described liquid crystal lifter, the door closure headstock gear comprises guide rail, push rod, lower limit assembly, following switch sea whelk, adjusting nut and the limit switch of being with slide block, the lower limit assembly is welded by brace, cross bar and trough of belt connecting rod, the hinge moving plate links to each other with slide block in the guide rail, the push rod slide block that is spirally connected, the brace of push rod lower end and lower limit assembly is rotationally connected, the brace lower end links to each other with following switch sea whelk and adjusting nut, adjusting nut can contact with limit switch, one termination of trough of belt connecting rod is the groove shape, and this end inserts the chain wheel that is riveted on driving chain.
The upper cover plate opening edge of the utility model liquid crystal lifter fits like a glove with upper cover plate after the door closure closure along there not being chamfering, and therefore, it is suitable that the liquid crystal lifter is made letter, and door closure good airproof performance when closed, does not also stir when being subjected to pressed by external force.Realize simultaneously intelligent control in use,, and realize the opening of door closure with closed by the rise and fall of the driving LCDs of same motor.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, 2, the casing 15 of liquid crystal lifter is embedded under the desktop, and its top panel and desktop maintain an equal level, and top panel is provided with opening, the door closure 1 of opening part for opening and close; The biside plate 12 that casing is relative is provided with opening guide groove 17.The door closure headstock gear is located in the casing 15, the slide block 21 that comprises guide rail 2, can slide relatively with guide rail 2, push rod 4, lower limit assembly, switch sea whelk 7, adjusting nut 19 and limit switch 8 down, the lower limit assembly is welded by brace 6, cross bar 18 and trough of belt connecting rod 20, brace 6 was in both sides in 20 minutes with the trough of belt connecting rod, linked to each other by cross bar 18.Display screen lifting gear is located in the casing 15, comprises upper and lower sprocket wheel 3,10 and driving chain 5, and lowering or hoisting gear drives display screen and rises and descend.Door closure 1 is spirally connected with hinge moving plate 14, and hinge moving plate 14 links to each other with slide block 21, and the opening guide groove 17 of casing biside plate inserts the door-hinge 11 that links to each other with hinge moving plate 14, and the movement locus that door closure 1 opens and closes is identical at the sliding trace of opening guide groove 17 with door-hinge 11.Push rod 4 is spirally connected with slide block 21, and slide block 21 inserts in the guide rail 2.The brace 6 of push rod 4 lower ends and lower limit assembly is rotationally connected, and brace 6 lower ends link to each other with following switch sea whelk 7 and adjusting nut 19, and adjusting nut 19 can contact with limit switch 8, thereby plays position-limiting action.One termination of trough of belt connecting rod 20 is the groove shape, and this end inserts the chain wheel 9 that is riveted on driving chain 5.When chain 5 motions, drive sprocket wheel 3,10 motions, and sprocket wheel 10 links to each other with the lower limit assembly by chain wheel 9, thereby drive the closure or openness of door closure 1.
Be the state of closing the door as shown in Figure 1, 2, descend by the driven by motor LCDs, when being in lifter inside fully down, the door closure closure.Open the door closure headstock gear, the transmission of driving chain 5 drives the rotation of trough of belt connecting rod 20, drive brace 6 motions by cross bar 18 again, and then push rod 4 is moved downward, push rod 4 promotes slide block 21 and moves downward, slide block 21 drives 14 motions of hinge moving plate, door closure 1 is moved downward, until opening door closure 1 fully with the sliding trace of door-hinge 11.The reverse drive of driving chain 5 just can realize the process of closing the door.
Be depicted as a certain state in the door closure opening procedure as Fig. 3,4.
