Abstract

The utility model relates to a built-in television lifting device used on a bed. The built-in television lifting device adopts a steel wire and a pulley block mechanism to complete the load (the load is a liquid crystal television normally) lifting, and guide sleeves which can be slid correspondingly are connected with cross beams and adapt automatically the manufacturing errors of two parallel guide tracks. The built-in television lifting device can be produced under the condition of simple device and technology, and has the advantages of compact structure, light weight and low cost. The built-in television lifting device can be used as an assembly and is matched and arranged on a multifunctional bed, a liquid crystal television display is lifted, and an ultra-thin and compact structure is matched with a bed structure. The user on the bed can operate the screen to extend from the inner part of a bed body in electric control mode, can lower and hide the screen to the bed tail when the television is not watched, and a bin gate can protect components at the inner part and maintain the external appearance of the bed.

Description

Built-in TV machine lowering or hoisting gear

Technical field

The utility model belongs to a kind of mechanical lifting gear, relates to the built-in TV machine elevating mechanism that is applied on the bed especially.

Background technology

The structure of lifting display device is usually used in some in appearance or the occasion of specific (special) requirements arranged on the space, when requiring overall structure thin as far as possible, common structure often needs to provide support simultaneously in the display both sides and lead with two guide rails, the relative broad of distance between this moment two closed slides, require firm guide pin bushing for cooperation, the higher depth of parallelism requires to bring very big difficulty to manufacturing and technology.Forms such as elevating mechanism can also the feed screw nut, chain, pinion and rack realize, but as being used for household products, then often exist weight greatly, greasy dirt, cost height arranged, need problems such as periodic maintenance.Also do not use at present the lowering or hoisting gear of built-in TV machine in bed

Summary of the invention

The device that the utility model provides a kind of display can stretch out automatically and hide, the mechanism that particularly uses employing wireline pulley group structure lifting display in bed.

The structure of this lowering or hoisting gear is, is fixed with guide rail 6 and guide rail 11 in the both sides of framework 5, the be slidingly connected guide rail 11 of framework one side of the fixedly connected sliding sleeve 13 of main beam 16 1 ends, sliding sleeve, a fixedly connected movable pulley 12 on the sliding sleeve; The be slidingly connected guide rail 6 of framework opposite side of the fixedly connected sliding sleeve 24 of secondary crossbeam 23 1 ends, sliding sleeve; Fixedly connected another movable pulley 25 on the sliding sleeve; Be fixedly connected with movable pulley 22 on the main beam; Main beam and secondary crossbeam are slidingly connected, and can appropriateness slide and rotation, can compensate the parallelism error between two guide rails automatically, guarantee that crossbeam slides on guide rail flexibly; Be fixed with fixed pulley 21 on the top of a body side frame, be fixed with fixed pulley 4 in a body side frame middle and lower part; Fixed pulley 4, fixed pulley 7, fixed pulley 21 are formed the fixed pulley group, and movable pulley 12, movable pulley 22, movable pulley 25 are formed running block.Steel wire rope 3 two ends are fixed on the framework 5, and the driving wheel 2 of running block and fixed pulley group and direct current generator driver element 1 is twined in the steel wire rope stage casing successively.

On crossbeam, be fixed with compressing tablet 14, be fixed with travel switch 9 on the position of compressing tablet 14 relatively on the bottom girder; Travel switch 18 is fixed on the top of framework.

On main beam, be fixedly connected with brace 15; LCD 20 is fixing with main beam 16 by display connection seat 19, brace 15, slides up and down with respect to framework 5 with crossbeam, realizes the display lifting.

Built-in TV machine lowering or hoisting gear employing steel wire, assembly pulley mechanism finish the lifting to load (often being liquid crystal TV set), the guide pin bushing that can slide relatively connects the foozle that crossbeam adapts to two closed slides voluntarily, its structure can be produced under simple equipment and process conditions, compact conformation, the hollow units that adopt more, in light weight, cost is low, and can not need intermittent oiling and maintenance.

Built-in TV machine lowering or hoisting gear can be used as assembly supporting be installed in multi-purpose bed on; the lifting lcd tv display; the structure fit of its ultra-thin compact structure and bed; but user's electrically controlled manipulation screen in bed stretches out in the bed body; can fall when not seeing and be hidden in tailstock, can protect internal works and keep the outward appearance of bed.
