Side due to backstay is wider face, and it is larger with contact area between above-mentioned support one and support two, and therefore, its connective stability is higher.
In above-mentioned foldable drawing board, the positioning recess one that described location division one is recessed into for backstay edge, described connector is cylindrical lock pin.
Positioning recess one and lock pin match, lock pin embed above-mentioned positioning recess once after support one and support two can be made to obtain lock in place.
In above-mentioned foldable drawing board, the positioning recess two that described location division two is recessed into for backstay edge, described connector is cylindrical lock pin.
Positioning recess two and lock pin match, and lock pin just can make support one and support two obtain lock in place after embedding above-mentioned positioning recess two.
Alternatively scheme, in above-mentioned foldable drawing board, described location division one is for being connected in the magnet one of backstay edge, and described connection pieces is iron block.
Alternatively scheme, in above-mentioned foldable drawing board, described location division two is for being connected in the magnet two of backstay edge, and described connector is iron block.
Can find out, what positioning recess and the cooperation of lock pin are replaced with magnet and iron block coordinates the same lock in place that can realize between support one and support two.
In above-mentioned foldable drawing board, described support one sidepiece has several uniform hinge holes, and the inner of above-mentioned backstay can be hinged on any one hinge hole place.
Due to environment difference of drawing a picture, angular dimension when needing adjusting pole one and support two to strut according to actual environment.Backstay the inner is hinged on corresponding hinge hole place just can achieve the above object.
In above-mentioned foldable drawing board, described backstay, hinge hole and connector form a lock cell in the side of support one, support two, and the both sides of described support one, support two all have a lock cell and two lock cells are symmetrical arranged.
Two symmetrical lock cells can be stable lock in place is carried out to support one and support two.
In above-mentioned foldable drawing board, the inner side of described support one has the eye-splice of protrusion, and described support two has recessed socket, and eye-splice above-mentioned after support one sticks together with support two is closed can insert above-mentioned spigot.
Eye-splice coordinates with socket the effect played secondary locking and locate.
In above-mentioned foldable drawing board, described socket and eye-splice form a secondary locking unit in the side of support one, support two, and the both sides of described support one, support two all have a secondary locking unit and two secondary locking unit are symmetrical arranged.
Two auxiliary positioning unit being symmetricly set on support one and support two both sides can improve the stability of its lock in place.
Compared with prior art, this foldable drawing board is owing to can locate by the support to support time closed and when opening by same location, and therefore, it is relatively simple for structure, and whole Foldable drawing board cost compare is low.
Meanwhile, under the effect of secondary locking unit, further improve its position stability.
In addition, the articulated position of backstay the inner can adjust, and therefore, the applicability of this Foldable drawing board is also higher.
