Technical field
The present invention relates to daily necessities, particularly the long stepless leveling device that withers of a kind of tables and chairs leg.
Background technology
Desk, stool, chair, instrument etc., because its leg length inequality is long, or because of ground injustice, or because designing the defect of processing, or because of distortion of making moist, or produce permanent deformation etc. because placing weight, write on all fours thereon, or place the tableware that liquid is housed, sit people, when particularly placing the equipment of vibrations, can produce and rock, these seem small usual problem, but often annoying our daily life, study and work.Tables and chairs rock not only impact and to write the quality of achievement waited, and produce noise, cause the discomfort etc. on health, even also can cause psychological puzzlement and worry, cause the accidents such as scald, make we have in the face of with must solve these and seem little minor issue.
Timeworn furniture are thrown away unfortunately, and bought a new tables and chairs not only not environmentally but also uneconomical, retracting genuine reprocessing then wastes time and energy, particularly packed and transported trouble.Though the objects such as a pad wooden unit can solve leg injustice, not firm, inconvenience is moved, and particularly when user uses generation vibrations, cushion block can be made to remove.Although the existing arrangement for adjusting height be arranged on tables and chairs on market, as hoof pin etc.But installation site is usually located at tables and chairs leg bottom, installation method is complicated, needs professional to operate; Particularly for when between each leg of tables and chairs, the long difference of leg is less, having any problem when existing structure is arranged on tables and chairs leg bottom or needing that original tables and chairs leg is clipped one section just can install, and this destroys comparatively large to original structure, limit its range of application.
Summary of the invention
Object of the present invention, is just to provide a kind of tables and chairs leg long stepless-adjustment leveling device.
The object of the present invention is achieved like this: the long stepless-adjustment leveling device of a kind of tables and chairs leg, comprises the seat that is connected, can wither leg, packing ring and stop nut; Be connected seat for being fixedly linked with tables and chairs leg, and adjustable support leg is connected to the bottom of the seat that is connected, and stop nut is connected to the top of the seat that is connected, and gasket sleeve to be connected on seat and between adjustable support leg and stop nut.
The described seat that is connected is columnar structured, and centre is provided with the mesopore with tables and chairs leg adaptation, and cylindrical shell is provided with external screw thread, and bottom is provided with outer step; Described adjustable support leg and stop nut are threaded with the seat that is connected respectively.
Described adjustable support leg top is cylinder, and bottom is cone, and cylinder is provided with internal thread, is provided with interior step between cylinder and cone, and adjustable support leg is connected by the lower thread of internal thread with the seat that is connected.
Described stop nut is provided with internal thread, and stop nut is threaded by the top of this internal thread with the seat that is connected.
Described packing ring is elastic washer.
The present invention be more than four legs or four legs tables and chairs provide a kind of structure simple, support firm, easy to adjust, collection is stablized, be practically applicable to the long stepless regulator of leg being convenient to install of one, thus eliminate because ground is uneven or the long tables and chairs caused of tables and chairs leg length inequality rock, article of eliminating the effects of the act are placed, shadow, to user's psychology, causes user's body and mind not accommodate worried tired.Be particularly suitable for the transformation to existing tables and chairs, even if gather effect equally to the chair legs of minim gap, also adjustment level can be needed used as tripod equipment simultaneously, or install multiple of the present invention time can be tables and chairs or other equipment adjustment levels are used.
