Description
Technical field
The present invention relates to daily necessities, relate in particular to installation joint, a kind of type hand side hoof pin.
Background technology
Instrument and equipment, tables and chairs, stool etc., because of ground injustice, or because designing the defect of processing, or because making moist distortion,Or produce permanent deformation etc. because placing weight, cause its leg length inequality long, if place establishing of accurate or vibrations thereonStandby, or place the apparatus of liquid is housed, or sit people, in the situation such as write on all fours, all can produce and rock, these are seenLike small usual problem, but often perplexing our routine work, living and studying. It is reported, Beijing pairThe desk and chair situation of 98Suo school of the whole city is investigated, and school desk's chair of 67% is defective. Chair and desk for pupils rocksThe not only impact quality of achievement waiting that writes, at quiet classroom generation noise, also can cause discomfort on health etc.,Even also easily cause psychological puzzlement and worry, cause the accidents such as scald, make us have to face with necessarySolve these and seem little little and important problem. Particularly, middle and primary schools are the person growth and development periodsMost critical period, and the time that student stops before the desk and chair of school be long-term, continuously, fixing. IfDesk and chair is sub-standard, very easily causes students in middle and primary schools bad, very easily tired with eye myopia, sitting posture, in the course of time,Figure is affected, and forms spinal curvature, hunchback etc. These illnesss, will cause teenager's health throughout one's lifeVery large impact.
Timeworn furniture have been thrown away unfortunately, and neither environmental protection is uneconomical again to buy new tables and chairs, retract the reprocessing of former factory time-consumingEffort, particularly packed and transported trouble. Though the objects such as a pad wooden unit can solve leg injustice, not firm, inconvenienceMove, particularly, in the time that user uses generation vibrations, can make cushion block remove. There is on the market now a kind of rubberThe paster of material, this paster has the big or small thickness of different size, but because its specification is limited, have " deficiency,Have a surplus for two " leveling defect, moreover bonding between rubber paster and table and chair feet only relies on glue service lifeLimited, although can carrying out height, traditional hoof pin regulates, its installation site is usually located at the bottom of tables and chairs and equipment legOn face, installation method complexity, needs professional's operations such as tapping of holing. Particularly between the each leg of tables and chairsThe long difference of leg hour, when existing structure is arranged on tables and chairs leg bottom, is had any problem or need to be original tables and chairs legClip one section and just can install, this destroys larger to original structure, limited its range of application. When go out exhibition orWhen Interim use equipment, how solving the tables and chairs problem of rocking causing because of ground injustice or leg length inequality length is also oneThe thing of unpleasant.
Summary of the invention
Object of the present invention, exactly in order to address the above problem, provides installation joint, a kind of type hand side hoof pin.
