Summary of the invention
The purpose of this utility model is unfavorable for arranging cleaning or using problem that is uncomfortable or tables and chairs collection inconvenience to solve existing desk for student chair, a kind of reasonable in design is provided, simple structure, easy location easy to hang, safe and reliable buckle-type student desk and chair.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of buckle-type student desk and chair, comprise desk, the chair supporting with desk, it is characterized in that being provided with crosspiece between described desk two pin, be provided with the hook part coordinated with crosspiece below the seat board of chair, crosspiece is less than or equal to the distance between hook part to back to the distance at desk edge.All fix few dynamic after the desk that student uses generally arranges, and chair transportability is larger, the technical program utilizes the space below desk, band bucket or desk principle not with bucket identical, above user's thigh, crosspiece is set, chair section except dividing except chair relying part is inserted the space below desk, is beneficial to the simple and easy cooperation of hook part and crosspiece, reach insert easily, take conveniently, the effect of safety and stability.
As preferably, the cross section of described crosspiece is rectangle, and hook part has the prong coordinated with rectangle height.Cross section is that the crosspiece of rectangle (comprising square) has enough intensity, ensures that chair will overturn and make crosspiece to be out of shape after inserting extension.
As preferably, described crosspiece is arranged between two pin of desk length direction, and the height dimension of crosspiece on desk is greater than the height dimension of hook part on chair.Desk for student is main mainly with class, and each row has multiple desks to be mutually close to sometimes, and the space of chair seat is the biggest factor utilized, so crosspiece is with main to being set to along desk length.
As preferably, the height of void that described hook part is reserved between being less than below crosspiece and desktop to the gauge of chair base surface.Namely the space requirement above crosspiece ensures that the seat part of chair stretches into wherein.
As preferably, the position that described hook part coordinates with crosspiece is provided with rubber layer.Rubber layer is crashproof, damping, noise reduction.
As preferably, described hook part is provided with half shaped as frame prong, is provided with positioner in prong, positioner comprises the steel ball being positioned at hole set on hook part body, one end of steel ball is provided with stage clip, and the other end of steel ball is provided with gland, and gland is provided with the through hole being less than diameter of the steel ball.Half horizontal shaped as frame prong is easily inserted extension, is easily taken off.When hook part coordinates with crosspiece, the stability of position between the two assisted by positioner.
As preferably, the positioner of described hook part is provided with several along prong width is equidistant, and crosspiece is provided with the spill arc crater that some places of coordinating with steel ball cambered surface equidistantly distribute along its length.Equidistant spill arc crater is conducive to chair in the location of desk length to diverse location.
As preferably, described hook part is provided with half shaped as frame prong, is provided with several positioners in prong, and described positioner comprises the alnico magnets be arranged in hook part body.Select the magnetic intensity of alnico magnets, be applicable to the use of all ages and classes layer student, alnico magnets, without the need to finding anchor point accurately completely, just can make chair hook part suck on crosspiece.
As preferably, described crosspiece is provided with the suction unit coordinated with alnico magnets along its length.As long as crosspiece adopt the material of sufficient intensity make just can, but need the steel point position that coordinates with alnico magnets of setting.
As preferably, described crosspiece is steel hollow rhs-structure.Crosspiece can adopt all steel to make, and chair can be hung along its length to inserting arbitrarily.
The beneficial effects of the utility model are: the design of half frame prong makes to insert hangs location easily, and the two-sided cooperation of square crosspiece and hook part is reliable and stable after making to insert and hanging; Be horizontally disposed with because hook part and crosspiece are, then chair of taking is easy and convenient; Insert after hanging and leave enough spaces below tables and chairs, be beneficial to cleaning; Classroom is in a row organized to the tables and chairs of row, chair is in good order after inserting and hanging.
