Description

The anti-squeezing hand device of desktop board

This patent is the divisional application of " patent name: the anti-squeezing hand device of desktop board, application number: 201110294294.X, the applying date: on September 28th, 2011 ".

Technical field

The present invention relates to school desk, particularly relate to the anti-squeezing hand device of desktop board.

Background technology

The desk of existing school comprises a pin, and table pin installs desktop, and this structure of desk is simple, but student has more book not have place to put, and just can only put on the table, and desktop is very highly folded, has both affected the normal study of student, and has made again classroom environment very messy.Also a class desk is had to be have shelf under desktop at present, a drawout cubicle is formed between shelf and desktop, there is backboard drawout cubicle rear end, the front opening of drawout cubicle, the shortcoming that this structure desk exists has: one is the book of bowing one's head and just can find in drawout cubicle that all will lean over when at every turn getting book, add that desktop has blocked light, drawout cubicle inside is comparatively dark, looks for book very inconvenient; Two is that distance between desktop and shelf is little, causes drawout cubicle volume little, puts the limited amount of book, if improved by desktop height and increase volume, then desk is too high, is not suitable for doing the homework, if reduced by height of shelf and increase volume, then the pin of student is not easily put into below the shelf of desk.Therefore, have now been developed the book frame school desk of large volume, the desktop of book frame school desk is convertible, because desktop is large, heavier, when desktop is toward ShiShimonoseki, careless finger (or other positions of hand) is squeezed between desktop and front apron or two side shields, light then squeeze pain, heavy then squeeze hinder, so there is the shortcomings such as larger potential safety hazard.

Summary of the invention

The object of the invention is the shortcoming existed to overcome prior art, there is provided a kind of when turnover table panel down closes, desktop and can finger be worn between front apron and two side shields, but desktop puts down the anti-squeezing hand device of use desktop board stably again.

The technical scheme of the anti-squeezing hand device of desktop board of the present invention is: the desk comprising a pin and desktop composition, backboard is equipped with after described desk, the both sides of desk are equipped with two side shields, between two side shields, be equipped with front apron and put book transverse slat, described desktop is turnover table panel, the rear end of turnover table panel is rotatably connected through tumbler with backboard, it is characterized in that there is hand hole between the top of front apron and two side shields and turnover table panel, back-up block is had in hand hole, described back-up block is arranged on front apron or two side shields, the head portion of back-up block contacts with turnover table panel.

The invention discloses a kind of anti-squeezing hand device of desktop board, comprise a pin, backboard, two side shields, put book transverse slat, front apron and turnover table panel etc., the rear end of turnover table panel and backboard are through tumbler rotatable engagement, when student will get book or put book, as long as upwards overturn by turnover table panel by tumbler, just can see the bookcase in desk, not need to bend over, also can not obstruct the light because of desktop, get book, to put book all very convenient.Book frame capacity is large, puts book many, reduces on table and puts book, be conducive to the environment learning and improve in classroom.Particularly above front apron and two side shields and between turnover table panel, there is gap hand hole, back-up block is had in hand hole, back-up block is arranged on front apron or side shield, when desktop is put down in closedown, hand (particularly point) can not by desktop and baffle plate extrude, use safety, has had back-up block desktop firmly can write.

The anti-squeezing hand device of desktop board of the present invention, described puts book transverse slat for transferring book transverse slat.Described book transverse slat of putting comprises upper cross plate and transfers book transverse slat.Described upper cross plate and transfer between book transverse slat and be equipped with perpendicular baffle plate.Upper cross plate is positioned at the upper forepart of two side shields, overhead higher, and comparatively near with desktop, when people are seated, pin is not blocked, and is applicable to keeping flat some books and stationery etc.; Transfer the lower rear portion that book transverse slat is positioned at two side shields, overhead comparatively near, transfer between book transverse slat and desktop comparatively dark, what form large volume stands up bookcase, and applicable setting discharges books in order.Described tumbler is turning cylinder and ear or hinge, and tumbler comprises various connector and hinge.
