Description

Read-write board

The utility model belongs to a kind of cultural goods, and rectifying sitting posture of student or the incorrect custom of some reading and writing postures are had better action, thereby reaches the effect of protection eyes and the normal development of assurance health.

It is planar that the common desk or the panel of desk all are level, like this, the people of reading and writing or office often forms both hands and pounces on custom on desktop, in the course of time, not only cause hypometropia, severe patient also is accompanied by trunk flexural deformation, and is just more outstanding for the heavy students in middle and primary schools' that are in the body development growth stage again of learning tasks influence.For this reason, existing manyly be used to change children's study and learning and pounce on the table the articles for use manufacturing technology of this bad habit and come out, can have mandatory effect owing to majority, user's utmost point sense discomfort, in case the disengaging condition is just recovered bad habit again, so difficulty is formed correct sitting posture and read-write posture.Do not reach the purpose of correcting fully.As be stuck in the Support for preventing myopia of pouncing on before a kind of children of preventing on the desk edge, and exactly when pouncing on before the student, support holds out against at its chest, and upper body can not be pounced on the desktop and achieve the goal.So be passive rectification, the long-term use might be influential to the normal development of child's chest.And, use also normal sense discomfort.Also there are the reading stand one class articles for use that adopt some relative desktops can change the angle of inclination to increase visual effect, the people is felt comfortably cool, also can reach the effect of vision protection.But only limit to the reading aspect, and just can not effectively solve for the incorrect rectification of writing posture, especially for the people who is engaged in office's secretarial work for a long time,, and use also inconvenient no matter be that Support for preventing myopia that clamps on the desktop or the reading stand that can change the inclination angle all are not suitable for.

The purpose of this utility model discloses exactly and does not a kind ofly need positive action can make conscious rectify of reading writing posture, thereby makes the user form the correct custom of sitting posture, and it is honest to reach trunk, the read-write board of vision protection effect.

The scheme that realizes above-mentioned purpose is as follows:

This read-write board is made of support, mainboard and the portable plate of putting books, by the feet and the mainboard of transform length constitute arbitrarily, key is that portable plate is that a dual-side is along longitudinal rail is arranged, chute is arranged in the guide rail, be horizontally connected with the press strip of putting books between two guide rails, there is the rectangular panel of the supporting plate of holder books the bottom; The mainboard front is smooth rectangular flat plate, and the slide rail that is being supported by two poles is housed on the base on it, is slidingly connected by halliard and portable plate.

Further scheme is to be connected with a telescopic halliard of length between slide rail on portable plate upper edge mid point and the mainboard.What finish the halliard function is a spooler that the folding and unfolding spring is housed in it, has chute on the slide rail, and active card is equipped with the hook that a lower end is connected together with halliard system in the chute.The leg that can change length is equipped with at the mainboard back side, the sliding part that is connected with spring between the guide rail of portable plate dual-side and press strip and slides in the guide rail chute.

Just can be made into one as stated above and be put on the desk, the mainboard gradient can change, portable plate about on the mainboard, the read-write board of left and right sides position-adjustable.During use, by changing the mainboard inclination angle, eyes are felt comfortably cool to degree, books are put under the press strip of portable plate again, suitable mobile press strip position makes it not influence sight line and convenient read-write ends.So both easy-to-read can write on books again.And in reading and writing process, the user will rectify the distance between sitting posture and maintenance eyes and books naturally.

The utility model has the advantages that by changing the mainboard angle, thereby eyes felt comfortably cool, by regulate portable plate about on the mainboard, position, the left and right sides, the position that can make books be in easy-to-read and write.Books are placed under the press strip of portable plate, have both guaranteed its stability, needn't worry page stirring under himself elastic reaction again.So, avoided the croucs hand to deacclimatize and write and read action by books.Thereby, not only protected eyes, make the upper body torso portion be in proper state naturally again, efficiently solve reading plate, the reading stand function singleness that has mandatory effect and avoided negative effect.

, as an embodiment such scheme is specified below in conjunction with accompanying drawing.

With reference to Fig. 1,2, the mainboard 6 of present embodiment and portable plate 9 usefulness planks, plastic plate or metallic plate all can.Slide rail 4 and guide rail 7 adopt aluminium alloy extrusions, support two poles 3 of slide rail and use metal pipe material.The top and bottom of two poles are with brace 12,14, and are affixed good with slide rail 4 and mainboard 6 tops respectively by screw.With the spooler 11 of the line box that is similar to liftable the sort of mahjong lamp as halliard 8, spooler and hook 5 are affixed good, and the hole 21 that the midpoint of the lower end of rope and portable plate 9 is opened binds.From arbitrary side of slide rail 4 hook 5 is sticked into the chute 13 and to get final product.The guide rail 7 of portable plate 9 both sides is screwed in the portable plate edge, and the supporting plate 1 that books fall that prevents of a high ejecting plate face 3-5 centimetre is fixed in the portable plate lower edge.Be connected with two elastic layerings 10 that can in the guide rail chute, slide between two guide rails.Feet 2 is the multi-joint telescoping tubular construction, regulates the requirement of mainboard gradient to satisfy; Its upper end is fixed in upper edge, the mainboard back side with connecting ring 15.

With reference to Fig. 1,5,6, slide rail 4 is used aluminium alloy extrusions, and to reduce weight, the center line of its one side is a chute 13.Hook 5 usefulness metals or plastic or other material all can, require to do smoothly, to reduce the frictional resistance with the slide rail contact site.The face at chute 13 places of slide rail should be in the isoplanar with mainboard 6 fronts, to guarantee that portable plate 9 contacts steadily with the mainboard face.

With reference to Fig. 1,3,4, portable plate 9 by the guide rail 7 of the supporting plate 1 of panel 22, lower edge, dual-side and and two guide rails between the elastic layering 10 that is slidingly connected constitute.Two guide rails 7 are the edge that is vertically fixed in panel 22 both sides, and supporting plate 1 is fixed in panel 22 lower edges, and is vertical with panel; Halliard 8 is fastened in the baffle plate 20 midpoint perforates 21 of panel upper edge.The two ends of press strip 10 are all slided part 17 by spring 16 and figure spike and are fixed together, and snap in its chute 18 from guide rail 7 suitable for reading 19 and get final product sliding part.

During use, as long as regulate the length of leg, mainboard reaches the inclination angle of instructions for use.Elastic layering on the portable plate is mentioned, books are placed in the panel under it, unclamp hand, books are promptly compacted.Utilize hook in slide rail, to slide function with halliard, regulate the correct position of portable plate.Can write or read by books without hand.Thereby guarantee that the user has the distance between a correct sitting posture and eyes and books and the best angle on sight line and books plane.Reach the effect of protection health and eyes.
