Abstract

A scissor-type guy driving stepless lifting table is a table or a platform which applies a lifting mechanism and a driving mode of patents of expansion lifting mechanism of frame type combined scissor and fork and expansion lifting mechanism of pulling-driving type frame combined scissor and fork, designs a foot stand adapting to the actual use of the table or the platform, is equipped with a driving assembly which is hidden under the table, and is pulled and lifted by electromechanic power, hand power or combination drive. The scissor-type guy driving stepless lifting table can lift the table or the platform stably, enlarge the stepless control applicable scope, has simple structure and low cost and convenience for manufacturing, can configure various tables, can be applied to workshops of shop laboratory and the like as an operating table so as to reduce the labor intensity and improve the work efficiency, can be applied to mobile stages of public places such as plaza hall and the like for meeting, reporting, showing and performing, can be applied to home or offices and the like as furniture of tables and tea tables, can change uses and applications frequently, and particularly is suitable for the use for the study and entertainment of children, can adapt to the change of height, give consideration to the safety and health, and provide freedom and convenience.

Description

Scissor type rope pulling driving stepless lift table

Technical field

The utility model is that a kind of lifting desk or platform improve, especially scissor type rope pulling driving stepless lift table.

Technical background

Desk and platform are life or working articles for daily use, and different purposes need different height.In existing technology, desk is manufactured into various adjustable samples to adapt to different lives or need of work with platform is existing.China's utility model patent " attached frame type combined shear-fork streatching-lifting mechanism " (patent No.: 200620101227.6) and " pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism " (patent No.: 200620102052.0) be a kind of novel elevating mechanism and type of drive, it is reliable and stable and can realize step-less adjustment that they are applied to desk or the simple lifting of platform structure.

Summary of the invention

The purpose of this utility model is that a kind of scissor type rope pulling driving stepless lift table will be provided, and uses new patented invention elevating mechanism and type of drive, uses desk or the simple lifting of platform structure reliable and stable, and can realize step-less adjustment.

The purpose of this utility model be achieved in that scissor type rope pulling driving stepless lift table by table top, cut fork row, foot rest and the driving assembly constitutes.Described table top is the plate body of definite shape and area; Described cut fork classify as two scissors rods intersect middle-end through bearing pin compose in series cross angle variable cut fork, cut fork by several and arrange to connect with the head and the tail of scissors rod and constitute; Described foot rest is that the identical device that separates up and down of one group of trident or many pronged shape is cut the fork frame of being disbursed from the cost and expenses, and support fork arm body is provided with slideway and tie point; Described driving assembly leads driving mechanism by guy cable pulley and volume and connects and composes, guy cable pulley is high strength rope for traction and the pulley that is complementary, volume leads the parts combination that driving mechanism is a power ring volume tractive drag-line, by electromechanics driving, driven by shaking or combined drive moving-coil volume tractive drag-line.Scissor type rope pulling driving stepless lift table is equipped and is invested foot rest up and down on the slideway and tie point of all support fork arms by some forks of cutting, the lower carriage of foot rest is placed in ground, upper bracket device volume leads driving mechanism and covers table top, pulley is set in the scissors rod interface of respectively cutting the fork row, some drag-lines coherent string of pile warp pulley respectively are around in all fork row of cutting, and connect volume and lead driving mechanism, lead driving mechanism circle volume tractive drag-line by volume and change through the pulley transferring power and cut the fork row and cut the fork angle and realize the stepless lifting of table top on the foot rest.

Scissor type rope pulling driving stepless lift table is used novel " attached frame type combined shear-fork streatching-lifting mechanism " and " pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism " patent elevating mechanism and type of drive, the actual foot rest that adapts that uses of design and desk or platform, driving assembly under the hiding table top of outfit is by motor-driven hand or combination drive tractive lifting, make desk or platform can lifting stablize the step-less adjustment scope of application and enlarge, and manufacturing simple in structure and safeguard conveniently cheap.

Description of drawings

Be described further below in conjunction with basic structure, principle and the typical exemplifying embodiment thereof of accompanying drawing this patent design:

Fig. 1 is the scissor type rope pulling driving stepless lift table construction profile diagrammatic sketch of round table surface on an example four fork foot rests.

Fig. 2 is the scissor type rope pulling driving stepless lift table construction profile diagrammatic sketch of rectangle table top on an example four fork foot rests.

Fig. 3 is the scissor type rope pulling driving stepless lift table construction profile diagrammatic sketch of round table surface on the routine trident foot rest.

Fig. 4 is that the guy cable pulley and the volume of scissor type rope pulling driving stepless lift table leads driving mechanism device structure illustration.

The figure mark: (1) table top, (2) are cut the fork row, (3) foot rest, and (4) guy cable pulley, (5) volume leads driving mechanism.

The specific embodiment

Scissor type rope pulling driving stepless lift table enforcement simple in structure is convenient, and it can use multiple material such as bamboo wood, metal to make.Cut fork row 2 optimums in the enforcement and select for use tubing to make, make to cut to pitch to be listed as both to have possessed higher-strength, can guy cable pulley 4 be hidden in the tube chamber as diagrammatic sketch again; The form of foot rest 3 can be done various variation according to the purposes needs, put ground support can acquire move the wheel be beneficial to mobile; Foot rest 3 is pitched the line image that row 2 appearances also can be added plane or solid with cutting, and can be designed to bending or animals and plants profile to beautify.The drag-line that drives the guy cable pulley 4 of assembly can be selected cable wire or stainless steel cable for use, and the pulley choosing is complementary with drag-line; Volume leads driving mechanism 5 can install random layer support or position at foot rest 3, but the most suitable being hidden under the table top 1; It can select for use dynamo-electric driving, driven by shaking or combination drive to be used as power, and some drag-lines of synchronous circle volume tractive together change all fork row 2 angles of cutting and realize stepless lifting.In force, the stepless lifting table of scissor-type guy rope can dispose the table top 1 of all size, shape, material, can be applicable to workshops such as laboratory, workshop is that the operation table is increased work efficiency to reduce labor intensity, can be applicable to public place assembly group such as square hall rally report and show the riser of performance, can be applicable to rooms such as family office makes table tea table furniture and can often change the use purposes, especially be fit to supply with the children life learning recreation and use, adapt to height and change and take safety and Health into account and provide freely and make things convenient for.
