The lifting mechanism is free in lifting, can lock height within a travel range, is firm in locking, is difficult to deform and is convenient in use and adjustment.

Description

A kind of elevating mechanism

Technical field

The utility model relates to a kind of elevating mechanism, is applicable to the furniture articles for use with lifting platform.

Background technology

The height of the table top of general tables and chairs can not up-down adjustment on the market, can not satisfy the needs of various differing heights.In order to overcome above-mentioned shortcoming, announcing in the Chinese patent storehouse has a kind of up-down desk and chair, especially student to use the metal up-down desk and chair, it adjusts the method for height with bolt locking, but loosening easily, deflection in its use, the excessive permanent deformation that also can cause column of coupling mechanism force needs often maintenance.Another kind of same table, the foot rest that comprises desktop, hollow, same table comprises upper support pipe, crossbeam, screw rod, sleeve pipe, the upper support pipe constitutes up and down by governor motion and foot rest, and slippage flexibly connects, it rotates by the helical gear that motor or handle drive in the upper support pipe, driving screw rod moves along sleeve pipe, the upper support pipe is moved along outer tube sleeve is upper and lower, realize the adjusting of height of table top, what right this same table adopted is the method realization of helical gear engaged transmission, have mechanism's complexity, shortcomings such as required precision height, cost height are not easy to produce in enormous quantities.

Summary of the invention

For overcoming above-mentioned shortcoming, the purpose of this utility model is to provide a kind of and can realizes easily and fast, the elevating mechanism of stable adjustment Lifting platform height.

For achieving the above object, the technical solution of the utility model is: a kind of elevating mechanism, be applicable to furniture office appliance with lifting platform, comprise lifting part and rolling part, described lifting partly is divided into the left and right sides, every side comprises guide rail, be connected on the guide rail and energy on, mobile down slide block, be located at guide rail up and down both sides on, lower sheave, seal wire, described guide rail vertically is fixed on inside one side of furniture office appliance cabinet, described slide block is used for and the fixedlying connected of Lifting platform, described seal wire one end is fixed on on the side slide, the other end is the top sheave by homonymy successively, lower sheave, the back partly is connected with rolling.Described Lifting platform is partly rolled up, is put seal wire by rolling and realizes elevating function.

As preferred embodiment of the present utility model: it comprises two winding wheels, driving mechanism and crossbeams described rolling part, described driving mechanism is fixed on the crossbeam, its output shaft is fixedlyed connected with two winding wheels, and the seal wire of described both sides connects one to one with winding wheel respectively.It is by the forward and backward of drive mechanism winding wheel, realize the receipts of seal wire and put, reach slide block and the liter of the table top of fixedlying connected and falling, and open and stop controlling the height of lifting and lock the lifting position of table top by driving mechanism with slide block, electronic positioning, convenient, fast.

As another preferred embodiment of the present utility model: described rolling partly comprises two winding wheels, rocking handle and crossbeams, described rocking handle passes crossbeam and is fixed on the crossbeam by angle bearing, its front end is fixedlyed connected with two winding wheels, and the seal wire of described both sides connects one to one with winding wheel respectively.It is realized the liter of table top by the hand rotation rocking handle and falls, and is simpler, convenient.

Pull out and make stable more, the work reliably of Lifting platform from the upper end in order to prevent Lifting platform, the utility model has also been established two spacing pulleys, it is installed in the two ends of crossbeam, described each winding wheel is provided with two grooves, draw a seal wire from the slide block of both sides respectively, its spacing pulley by homonymy respectively with corresponding winding wheel on another groove connect.

Unobstructed for what guarantee to move, described slide block links to each other with guide rail by bearing.

For the stability that guarantees to move, be provided with two groups of bearings in the described slide block.

Driving mechanism described in the utility model comprises motor and decelerator.

The utility model lifting freely, and can be in stroke range lock height, and locking is firmly not yielding, uses easy to adjust.Use that this up-down desk and chair behind the utility model is simple in structure, good manufacturability, handsome in appearance generous, cost is low, be convenient to produce in enormous quantities.The utility model is its table surface height of lifting as required and neatly, especially is suitable for adolescent student, and it can be according to individual sub-height, eyesight situation and scientifically determine the height of desk it to be grown up healthy and sound.On the other hand after the Lifting platform hierarchical design, important item can be placed that Tsang is difficult for losing in lower floor's table top in the table body.
