Abstract

The utility model discloses a writing indicating board which is a cultural teaching article. The writing indicating board is made of novel materials, is made into a writing board whose board surfaces are changeable, and substitutes for the traditional teaching tool of a blackboard. The writing indicating board comprises a bracket, a frame and the board surfaces. In addition, the structure of the board surfaces are reformed into three-layer structural forms. A magnetic clamp sheet is clamped between two plastic boards. Ironware or magnetic nails and magnetic bars can be adsorbed and then pieces of paper and charts can be hung. Simultaneously, two surfaces of a white plastic board can also be used for writing the lettering of a fountain pen. The most important is that a ratchet mechanism is adopted for controlling the central axis of the frame, which makes the change of the board surfaces flexible, rapid, reliable, fixed and steady.

Description

Writing display board

The utility model discloses a kind of indicator board of writing, it belongs to the school supply and stationery technical field.

Mostly commercially available various blackboard, clipboard, indicator board are positive that use writing words or indicator diagram.The reverse side of plate can not utilize.Perhaps utilize the troublesome poeration of reverse side, use and change plate face suspension inconvenience.

The purpose of this utility model will solve the plate face problem that makes full use of exactly.Design a kind of two sides with writing indicator board.This plate can be write with dustless water-color paintbrush of all kinds, and the paper of also can follow closely with magnetic, the magnetic stripe attaching being write also can be done the screen of projectors such as magic lantern.This plate is simple in structure, and the plate face is changed convenient, flexible, plate face fixing-stable.

Task of the present utility model is that following technical scheme is finished: developed a kind of indicator board of writing.This also has support, framework and plate face.This book is write the plate face that indicator board adopts and is made of three-decker.The intermediate plate of the magnetic or irony of clipping between the positive and negative two sides of this plate face.The plate face of these three layers of glued constructions is embedded in the framework.The central shaft two ends of framework are rack-mount.On arbitrary end of this central shaft ratchet mechanism is installed.This mechanism is also rack-mount.

This book is write designed framework of indicator board and central shaft thereof, and it can laterally be installed, and also can vertically install, and correspondingly on the also rack-mount accordingly left or right vertical beam of ratchet mechanism, perhaps is installed on the following crossbeam of support.

This book is write the designed rack-mount ratchet mechanism of indicator board, and it is assembled in the hub successively by square shaped teeth ratchet, pull bar ratchet, spring.Wherein on the pull bar ratchet stretches out the outer end of hub, handgrip is installed.This ratchet center fixation is connected on the central shaft.

This book write all attach on the positive and negative two sides of the designed plate face of indicator board adsorbable on the plate face, the magnetic nail or the magnetic stripe of different shape.

This book of accompanying drawings is write the embodiment of indicator board.As shown in the figure:

Fig. 1 is for writing indicator board front front view.Support 1 is arranged, framework 2, plate face 3, central shaft 5, ratchet mechanism 6, following crossbeam 7, magnetic nail 13, magnetic stripe 14, castor 15 among Fig. 1.

Fig. 2 is the A-A section enlarged diagram of Fig. 1.Have among Fig. 2: framework 2, plate face 3, intermediate plate 4.

Fig. 3 is the structure enlarged diagram of ratchet mechanism.Central shaft 5 is arranged, square shaped teeth ratchet 8, pull bar ratchet 9, spring 10, hub 11, handgrip 12 among Fig. 3.

This book is write indicator board as shown in the figure: adopt aluminium alloy system support 1, its size: wide * height is 1650 * 1400mm.Aluminum alloy frame 2, its size: long * wide be 1500 * 1000mm.Plate face 3 is two irony intermediate plates 4 of moulding a homalographic of panel clipping in vain, its size: long * wide * thick be 1450 * 950 * 45mm.Castor 15 is a universal wheel.This plate as long as mention handgrip 12, thereby pulls up pull bar ratchet 9 when changing the plate face, ratchet 8 promptly with central shaft 5 Rotate 180 degree, puts down handgrip 12, and ratchet 9 can reach in the square shaped teeth mouth, thereby fixes central shaft 5 and framework 2, and the integral slab face promptly is reversed the location.

This Writing display board, plate face cleaning is attractive in appearance, adopts ratchet mechanism to make this plate use the converter plate face flexibly rapidly stable, fixed, easy to use. Magnetic nail, magnetic stripe can hang paper form. The positive and negative two sides of plate face all can use water-color paintbrush to write, and has convenient durable advantage.

Claims

1, a kind of indicator board of writing, it includes support (1), framework (2), plate face (3), it is characterized in that: described plate face (3) is made of three-decker, the intermediate plate (4) of the magnetic or irony of clipping between the positive and negative two sides of this plate face (3), the plate face (3) of these three layers of glued constructions is embedded in the framework (2), central shaft (5) two ends of this framework (2) are installed on the support (1), ratchet mechanism (6) is installed on arbitrary end of this axle (5), and this mechanism (6) also is installed on the support (1).

2, according to the described indicator board of writing of claim 1, it is characterized in that: described framework (2) and central shaft (5) thereof, it can laterally be installed, also can vertically install, correspondingly ratchet mechanism (6) also is installed on the left or right vertical beam of support (1) accordingly, perhaps is installed on the following crossbeam (7) of support (1).

3, according to claim 1 or the 2 described indicator boards of writing, it is characterized in that: the described ratchet mechanism (6) that is installed on the support (1), it is by square shaped teeth ratchet (8), pull bar ratchet (9), spring (10), be assembled in successively in the hub (11), wherein on pull bar ratchet (9) stretches out the outer end of hub (11) handgrip (12) be installed, this ratchet (8) center fixation is connected on the central shaft (5).

4, according to the described indicator board of writing of claim 1, it is characterized in that: on the positive and negative two sides of described plate face (3), all attach adsorbable on plate face (3), magnetic nail (13) or the magnetic stripe (14) of different shape.
