Description
Technical field
The invention belongs to military equipment equipment, specifically a kind of portable military map chart board.
Background technology
The auxiliary appliance that map chart board is wall hanging or places military map, accurately determines a position, accurately now contrasts orientation, field mapping and modulation sketch map, being the conventional equipment of military training and operation, is also that military topography is imparted knowledge to students one of required main teaching equipment.For a long time, in each universities and colleges of the entire PLA and field army, map chart board is all wooden monoblock chart board, and this chart board quality is good, durable.But this chart board area is comparatively large, carry inconvenience, and easily give away one's position under field condition, be not inconsistent with the requirement of " with light packs ", " hidden " in actual combat, this is also that this chart board carries few major reason in actual combat; This wooden chart board skin hardness is comparatively large in addition, more difficult at fine needle slotting mutatis mutandis above, affects operating speed.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, there is provided a kind of portable military map chart board, 1/4th sizes only having expansion folded up by this map chart board, can put into military standard 07 satchel, take up room little, easily carry, good concealment; Front flat smooth and soft or hard are suitable, and easy contact pin, facilitates map to fix.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is to provide a kind of portable military map chart board, comprise the first identical chart board of size, the second chart board, the 3rd chart board and the 4th chart board, described first chart board, the second chart board, the 3rd chart board and the 4th chart board are all double-deckers, be made up of steel plate and foamed board, its light plate is the back side, and foamed board is front; By the first gemel connection between first chart board and the second chart board, by the first gemel connection between 3rd chart board and the 4th chart board, by the second gemel connection between first chart board and the 4th chart board, second chart board, the 3rd chart board and the 4th chart board are also hinged with male buckle part, there is female buckle part first chart board, the second chart board and the 4th chart board corresponding position, described male buckle part side has catching groove, and catching groove matches with female buckle part, and described first hinge, the second hinge, male buckle part and female buckle part are all located on steel plate.
/ 4th sizes only having existing wooden monoblock chart board folded up by portable military map chart board of the present invention, fold up to take up room little, easily carry, good concealment, easy to use, are applicable to field operations needs; Stretching out rear male buckle part and female buckle part coordinates fixing, can prevent it from bending, improve the flatness on surface; Front is smooth foamed board, and soft or hard is suitable, easy contact pin, and does not affect pencil and write picture; The back side is steel plate, nonmagnetic, does not affect the use of north arrow, even and if meet water also can not get rusty, durable in use.
Described second hinge is built up by three the first hinges, and the adjacent hinge of three the first hinges connects, and junction rivet is fixed.More easily this portable military map chart board can be folded up, and front and front face when ensure that folding, the back side and rear-face contact, prevent the back side steel plate from scratching front foamed board.
Be provided with pad between described first hinge and steel plate, portable military map chart board of the present invention can be made to fold up more smooth.
Described positive hasp has support plate, and support plate is located at the side opposing with catching groove, pulls support plate can be more prone to, be coordinated with female buckle part by male buckle part effortlessly with hand.
