Abstract

A riser for lifting products comprising chair and desk is a lifting mechanism, which takes back the steel wire (3) and lifts the pulley (4) with steel wire force, when a shaking handle (9) is rotated toward a direction. Therefore purpose for lifting the operating face (1) is realized when the supporting column (2) is raised. The rotation will stop at any time and the operating face (1) is fixed at an instant height whenever. A lifting mechanism sends out the steel wire (3) with the spring downward pulling force, when a shaking handle (9) is rotated toward a direction. Therefore purpose for descending the operating face (1) is realized when the supporting column (2) is descended. The rotation will stop at any time and the operating face (1) is fixed at an instant height whenever.

Description

Lifting device for desk and chair
Under technical field the present invention relates to a kind of device, the up-down desk and chair that life and school are used especially with study and work platform such as up-down desk and chair.
Background technology is present, lifting series products such as the existing tables and chairs of China, substantially can not independently finish descending operation for children, some also needs to use aid and adjusts height, and these have all greatly limited the demand that children carry out the tables and chairs lifting at any time.All differ more with age height among the children now, at school's frequent string seat also, children need independently finish the lifting of tables and chairs in the time of more, reach comfortable use tables and chairs and finish one's homework and learn.Children are in the period of growing up, and can not be finished the lifting of tables and chairs by oneself at any time, have influenced growing up healthy and sound of children so to a great extent.
Summary of the invention is in order to overcome the deficiency that existing up-down desk and chair product children can not independent complete operation, the invention provides a kind of table and chair that is used for and produce brilliant lifter, this lifter not only helps children's operation, also can be effective for adult use simultaneously, and can be applied to the lifting of various operating surfaces.
The technical solution adopted for the present invention to solve the technical problems is: adopt characteristics such as movable pulley, worm and gear mechanical mechanism and spring tension, make lifter rise and to descend and random positioned effect.Be used in the tables and chairs lifting, and because crank torsion is less, therefore very little children also can complete operation, reaches the demand whenever anyone finishes lifting.
The invention has the beneficial effects as follows that can not having the adult to reach at one's side need not be any aid the time, only by children oneself rotation lifter crank, just can easily finish the lifting of article such as tables and chairs.No matter be in a lot of school of student, when still own independent study is lived, can both guarantee only use height, the writing posture of the most comfortable reaches the purpose that children grow up healthy and sound
The present invention is further described below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is overall structure figure of the present invention.
Product structure figure when Fig. 2 is the application of part different product
Operating surface on 1. among Fig. 1,2. the upper support post 3. promotes steel wire, 4. lifting tackle, 5. drop-down spring, 6. lower support post, 7. lower support face, 8. elevating mechanism, 9. crank.
A. same table among Fig. 2, b. chair lift, c. combined bookshelf same table, the double same table of using of d..
The specific embodiment is in Fig. 1, when a direction rotation and lifting mechanism (8) crank (9), regain and promote steel wire (3), utilize the pulling force rising lifting tackle (4) of steel wire, thereby upper support post (2) is raise, reach the effect of rising operating surface (1), stop the rotation at any time, operating surface (1) is fixed on instant height at any time.
When another direction rotation and lifting mechanism (8) crank (9), emit and promote steel wire (3), utilize drop-down spring (5) pulling force downwards, finishing upper support post (2) descends, reach the decline of operating surface (1), stop the rotation at any time, operating surface (1) is fixed on instant height at any time.
Support column can adopt pipe, also can adopt square tube.
In embodiment illustrated in fig. 2, this lifter can be used for same table (a), chair lift (b), combined bookshelf study table (c), two opening and closing and tables and chairs multiple lifting series products such as (d).

Claims (2)

  1. One kind can be in order to adjust lifter of table (chair) height, utilize elevating mechanism (8) folding and unfolding pierce tap movable pulley (4) and utilize the regulating action of spring (5) pulling force complete operation face height, at any time stop elevation and subsidence mechanical and rotate, operating surface is fixed on instant height at any time; The elevating mechanism plane of rotation can laterally can be vertical, is that a driving shaft and a driven pulley are meshed.
  2. 2. according to the feature of lifter, this lifter can be used for table, chair, combined bookshelf desktop, Double chair and table and many humans combined table and chair assembly, needs the product hand-operated lifting or the electric up-downs such as operating table surface of lifting.
