Description
Technical field
The present invention relates to the teaching aid field of teaching, particularly to a kind of telescopic map board holder.
Background technology
The shelf of existing drawing is integrally fixed at together with desk, and the size of shelf is fixing, it is impossible to flexible,
Thus determining a drawing table can only be for a drawing board, and drawing table is unified is placed on inside a classroom, paints
The classroom quantity of figure is also limited, and the when that inside school, the class of drawing being more, the classroom of drawing is the most not enough, this
Just make troubles to the drawing of student.
Summary of the invention
In order to overcome at least one problem present in existing background technology, the present invention proposes a kind of simple in construction, use
Convenient telescopic map board holder.
To achieve these goals, the present invention proposes a kind of telescopic map board holder, including: fixed frame；Ratchet mechanism,
Be fixedly installed with in described fixed frame；Swivel mount, is connected with described fixed frame by described ratchet mechanism, and described rotation
Frame is by the angle between described ratchet mechanism scalable and described fixed frame；First bracing frame, is arranged on described swivel mount
On, rotate with described swivel mount, and the distance between scalable and described swivel mount；Second bracing frame, and described fixing
Underframe is connected, and the distance between scalable and described fixed frame.
Optionally, described first bracing frame is connected by four expansion brackets being connected with described second bracing frame.
Optionally, described expansion bracket includes holding piece, high balance sheet and telescopic chute.
Optionally, described fixed frame includes stator, holding piece, telescopic chute, described fixed frame and described expansion bracket
With the use of.
Optionally, connected by screw, nut between described expansion bracket, described fixed mount and described swivel mount.
Optionally, described ratchet mechanism includes stator, revolving fragment, tongue sheet and serrated slot, and described stator is fixed on
On described fixed frame and described swivel mount.
Optionally, between described stator and described revolving fragment, between described revolving fragment and described serrated slot, described sawtooth
All connected by a rotary shaft between groove and described stator.
Optionally, the material of described fixed frame, described first bracing frame, described second bracing frame and described swivel mount is
Wood materials, the material of described ratchet mechanism is metal.
The beneficial effect of the telescopic map board holder of the present invention is mainly manifested in: the letter of the present invention telescopic map board holder structure
Single, easy to use, can use on most desk, effectively solve drawing class of school more when drawing
The problem that table is not enough.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing 1-5, the invention will be further described.
Telescopic map board holder described in patent of the present invention is by ratchet mechanism 1, fixed frame 2, expansion bracket 3 and swivel mount
4 compositions, fixed mount is fixed on desk together with expansion bracket 3, and swivel mount 4 is used for expansion bracket 3 clamping drawing board together
, ratchet mechanism 1 is used to the angle between regulation swivel mount 4 and fixed mount, between namely regulation drawing board is with desktop
Angle, it is achieved thereby that arbitrarily raise and reduce the angle of drawing board and desktop, facilitates picture.First bracing frame 16, is arranged on
On described swivel mount 4, rotate with described swivel mount 4, and the distance between scalable and described swivel mount 4；Second supports
Frame 17, is connected with described fixed frame 2, and the distance between scalable and described fixed frame 2.Described first bracing frame 16 He
Described second bracing frame 17 is connected by four connected expansion brackets 3.And, telescopic map board holder fixed frame 2, expansion bracket
3 and swivel mount 4 be all wooden, only ratchet mechanism 1 is irony, and overall weight is relatively light, it addition, this contractible graph grillage
It is demountable, it is simple to carry.
Telescopic map board holder is made up of ratchet mechanism 1, fixed frame 2, expansion bracket 3 and swivel mount 4.Ratchet mechanism 1
Being made up of stator 12, revolving fragment 13, tongue sheet 14 and serrated slot 15, stator 12 is integrally fixed at fixed frame 2 and rotates
Above frame 4, connected by rotary shaft between stator 12 and revolving fragment 13, by rotating between revolving fragment 13 and serrated slot 15
Axle connects, and is connected by rotary shaft between serrated slot 15 and stator 12.
Fixed frame 2 is made up of stator 12, holding piece 6, telescopic chute 8 and rotary shaft, and fixed frame 2 is with expansion bracket 3
With the use of, map board holder is fixed on desk, expansion bracket 3 is with passing through screw 5 and nut 11 between fixed mount and swivel mount 4
Connect, wherein expansion bracket 3 has high balance block 7 above with swivel mount 4, it is ensured that map board holder is with the contact in desktop and chart board face
It is the most all consistent.
Expansion bracket 3 is made up of holding piece 6, high balance block 7 and telescopic chute 8.Swivel mount 4 stator 12, holding piece 6, height
Degree balance weight 7, telescopic chute 8, rotating hole 10 form.
Student is by being combined together fixed frame 2 and expansion bracket 3, according to the size of the size adjustment cooperation of desk,
Thus map board holder can be fixed on suitable desk, solid by screw 5 and 11 fixed frame 2 of nut and expansion bracket 3
It is scheduled on together, then swivel mount 4 is linked together by rotary shaft with fixed frame 2, then ratchet mechanism 1 with the fixing end
Frame 2 and swivel mount 4 are fixed together, then swivel mount 4 and expansion bracket 3 are coordinated, the size coordinated according to the size adjustment of chart board,
Thus suitable chart board can be placed on map board holder.
Although the present invention is disclosed above with preferred embodiment, so itself and non-limiting present invention.Technology neck belonging to the present invention
Territory has usually intellectual, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore,
Protection scope of the present invention is when being as the criterion depending on those as defined in claim.
