Description

A kind of school desk

Technical field

The present invention relates to a kind of school desk.

Background technology

The structure of traditional school desk is generally all made up of table and table leg.Wherein table generally all adopts the material such as force fit plate or solid wood board to make, the table overall weight made of this traditional material is comparatively large, makes the Portability of school desk poor, and the table too rigidity that force fit plate or solid wood board are made, student is when writing, and writing experience is not good.

In addition, the table shape of existing school desk is generally rectangle, its edge and corner place hardness high, and comparatively sharp, there is potential safety hazard in easy gouge student, for this reason, market there is the crashproof edge cover strip of some crashproof polyurethane, and be bonded in the edge of school desk by adhesive sticker, to reduce table edge, the collision of student is injured.But the crashproof edge cover strip of polyurethane that this adhesive sticker is fixed after a long time use, still easily comes off or plays limit, fixing less stable.

Summary of the invention

The object of the invention is the shortcoming and defect existed to overcome prior art, and provide a kind of reasonable in design, writing experience is good, supporting & stablizing is reliable and the school desk that anti-collision effect is reliable and stable.

For realization is above-mentioned purpose, technical scheme of the present invention includes table and table leg, described table includes top panel, lower panel and stickup and is fixedly installed on polystyrene foam plate between top panel, lower panel, and on the periphery of described table, injection moulding is surrounded and is fixedly installed polyurethane foam bound edge cover.

By this setting, change the table of traditional rigidity into above-mentioned compound desk plate structure, top panel provides surface rigidity to support for the behavior such as writing, polystyrene foam plate is then for table provides the elastic writing feedback force of small radian, student is when writing thus, the pressure energy of writing of nib is delivered to polystyrene foam plate, the elastic force reaction force of polystyrene foam plate feedback feeds back to the nib of student by top panel, thus, make the action of writing of pen very light, student only needs to write the person's handwriting that just can write out enough concentration lightly, therefore, significantly reduce the labour intensity write, improve writing experience, in addition, this setting, the composite construction of table significantly reduces its weight, make it easy to carry and carry, and this arrange described polyurethane foam bound edge cover fixing-stable reliable.

Further setting is that described top panel and lower panel are force fit plate, and its thickness is the 1/20-1/10 of polystyrene foam plate thickness.By this setting, through practice test, top panel is supported the rigid surface write and just right to the elastic feedback of nib, make to write the minute elastic deformation that is unlikely to table and lose shape, and it is good to write feedback experiences, writes easily.

Further setting is described lower panel and polystyrene foam plate offers the injection moulding connecting hole corresponding with table leg quantity and installation site, in this injection moulding connecting hole, injection moulding is fixedly installed table leg adapter sleeve, described table leg adapter sleeve includes injection moulding scarf and is fixed on the convex cap in injection moulding connecting hole and is arranged at the annular nib of convex cap lower end periphery, the upper surface of described annular nib is the inclined-plane of the 0.5mm-2mm that is inclined upwardly from inside to outside in its free state, under the state that injection moulding connecting hole is fixed in the injection moulding of table leg adapter sleeve annular nib upper surface elastic deformation and form plane snug fit with the lower surface of lower panel, the upper surface of this annular lug is provided with the annular groove that multiple tracks is mutually concentric.

Because table includes the composite construction of polystyrene foam plate, traditional connected mode cannot ensure the stable connection of table leg, and is arranged in the injection moulding connecting hole that the injection moulding of table leg adapter sleeve to be fixed on table by this, and connective stability is good, in addition, this arranges annular nib and also has following effect cleverly, and the upper surface of this annular nib becomes being inclined upwardly of minute angle, when the injection moulding of table leg adapter sleeve is fixed, should annular nib elastic deformation is also attached to the lower surface of lower panel tightly, and in this elastically-deformable process, in annular nibair in annular groove can be extruded because of its deformation, and after moulding, this multiple tracks annular groove has become relative region of no pressure, and thus, external atmosphere pressure is by right annular nib is exerted pressure, and makes it be fixed on tightly on table, drastically increasesthe fixing stability of table leg adapter sleeve.

Further setting is that the convex cap inside of described table leg adapter sleeve arranges and longitudinally under shed is provided with internal thread hole, and the upper end of described table leg arranges the external screw thread with the internal thread hole screw thread secure fit of this convex cap.By this setting, table leg is facilitated to connect.

Further setting is that described table leg includes hollow leg pipe and is fixed by socket the leg assemblies in hollow leg pipe upper end, and described external screw thread is arranged at the upper end of leg assemblies.

To be that the bottom of described hollow leg pipe is sheathed be fixed with a footmuff in further setting.

Further setting is that described top panel and polystyrene foam plate longitudinally offer toy storage hole, is embedded and is fixedly installed toy storage box in this toy storage hole.By this setting, the present invention is made to have the function of toy storage.

Below in conjunction with specification drawings and specific embodiments, the present invention is described further.
