Description
Technical field
The present invention relates to daily necessities, more particularly to a kind of tables and chairs leg grows the stepless leveling device that withers.
Background technology
Desk, stool, chair, instrument etc., because its leg length inequality is grown, or because ground is uneven, or because designing the defects of processing,
Or permanent deformation etc. is produced because of deformation of making moist, or because placing weight, write on all fours on it, or the tableware equipped with liquid is placed,
People is sat, when particularly placing the equipment of vibrations, can produce and rock, these seem the problem of small usual, but annoying me often
Daily life, study and work.Tables and chairs rock not only influence write wait quality of achievement, generation noise, cause on body
Discomfort etc., or even can also cause psychological puzzlement and worry, cause the accidents such as scald so that we have to face and must
It must solve these and seem little minor issue.
Timeworn furniture have thrown away that unfortunately, to buy a new tables and chairs not only not environmentally but also uneconomical, retract genuine reprocessing then time-consuming expense
Power, particularly packed and transported trouble.Though the objects such as pad wooden unit can solve leg injustice, not firm, inconvenience is moved, particularly
When user is using vibrations are produced, cushion block can be removed.Although in the market has been installed on the height adjustment device on tables and chairs,
Such as hoof foot.But installation site is usually located at tables and chairs leg bottom, installation method is complicated, it is necessary to which professional operates；Particularly pair
When the long difference of leg is smaller between each leg of tables and chairs, has any problem or need original table when existing structure is installed on tables and chairs leg bottom
Chair leg is clipped one section and can just be installed, this is larger to original structure destruction, limits its application range.
The content of the invention
The purpose of the present invention, in that a kind of tables and chairs leg is provided and grows stepless levelling device.
The object of the present invention is achieved like this：A kind of tables and chairs leg grows stepless levelling device, including solid link seat, can wither branch
Foot, packing ring and stop nut；Solid link seat is used to be fixedly linked with tables and chairs leg, and adjustable support leg is connected to the lower part of solid link seat, locking
Nut is connected to the top of solid link seat, and packing ring is sleeved in solid link seat and between adjustable support leg and stop nut.
The solid link seat is columnar structured part, and centre is equipped with the mesoporous being adapted to tables and chairs leg, and cylinder is equipped with external screw thread,
Bottom is equipped with outer step；The adjustable support leg and stop nut are threadedly coupled with solid link seat respectively.
The adjustable support leg top is cylinder, and lower part is cone, and cylinder is equipped with internal thread, cylinder and cone it
Between be equipped with interior step, adjustable support leg passes through the lower thread of internal thread and solid link seat and connects.
The stop nut is equipped with internal thread, and stop nut is threadedly coupled by the internal thread with the top of solid link seat.
The packing ring is elastic washer.
The present invention for tables and chairs more than four legs or four legs provide it is a kind of it is simple in structure, support it is firm, easy to adjust,
Collection is stablized, is practically applicable to the integral long stepless regulator of the leg being easily installed, so as to eliminate because ground is uneven or tables and chairs leg length
Tables and chairs caused by Length discrepancy rock, and article of eliminating the effects of the act is placed, and shadow causes user's body and mind not accommodate tired to user's psychology
It is angry tired.It is particularly suitable for the transformation to existing tables and chairs, though effect is equally gathered to the chair legs of minim gap, while can also conduct
Three foot equipment need adjust level used in, or installation it is multiple the present invention when can be tables and chairs or other equipment adjustment level used in.

Embodiment
Referring to Fig. 1, coordinate referring to Fig. 2, tables and chairs leg of the invention grows stepless levelling device, including solid link seat 1, connected screw
2nd, adjustable support leg 3, packing ring 4 and stop nut 5.Solid link seat 1 is respectively connected with by screw thread and adjustable support leg 3 and stop nut 5, pad
Circle 4 is sleeved in solid link seat 1 and between adjustable support leg 3 and stop nut 5.The material therefor of part of the invention main for plastics or
Light metal etc., the signal being attached to when being used on chair are as shown in Figure 8.
Referring to Fig. 3, coordinate referring to Fig. 1, Fig. 2, Fig. 8.Being dug among solid link seat 1 in the present invention has hole, and pore size is sufficiently large
To be sleeved on the outside of tables and chairs leg, the shape in hole can be square hole, circular hole, elliptical aperture etc., be determined by the shape of seat leg；It is connected
1 outer contour of seat is cylindrical surface and long enough, and outer contour is equipped with external screw thread 12, and outer contour bottom is a bit of overhanging outer step
11；Radial hole or radial screw bore 13 are equipped with solid link seat 1, the screw 2 (or bolt) that is connected passes through this radial hole or radial direction screw hole
13 are connected with tables and chairs, and the screw 2 that is connected can be that the leg of (wood) tables and chairs is interior or bolt is with by it to screw in for self-tapping screw
Pressure, the frictional force held out against to tables and chairs leg makes solid link seat 1 be fixed as one with tables and chairs.
Referring to Fig. 4, coordinate referring to Fig. 1, Fig. 2.3 top of adjustable support leg in the present invention is cylinder, and lower part is cone, circle
