Description

A kind of foldable adjustable angle caricature drawing boards

Technical field

The utility model is related to a kind of caricature articles for use, specifically a kind of foldable adjustable angle caricature drawing boards.

Background technology

Drawing boards currently used for caricature drawing are broadly divided into electrical type and traditional plate face class, and electrical type drawing boards are Using the board device of touch screen and display screen, be similar to present tablet computer, although the drawing boards of electrical type obtain it is larger Development, but be unable to do without the driving of electric energy, once power depletion will can not use, and the plate face ruler of this kind of drawing boards Very little often little, the drawing boards more than 24 cun or more are even more expensive, therefore, there is an urgent need to a kind of foldable easy to carry, And the plate face caricature drawing boards of adjustable angle.

Utility model content

To solve the above problems, the purpose of this utility model is to provide a kind of foldable adjustable angle caricature drawing boards.

The utility model to achieve the above object, a kind of foldable adjustable angle caricature drawing boards, including mainboard and logical It crosses hinge and is fixed on the upper folded sheet of mainboard lower edges and lower folded sheet, and position respectively after upper folded sheet and the folding of lower folded sheet In the two sides of mainboard, after so that folded sheet and lower folded sheet is opened, mainboard, upper folded sheet, lower folded sheet form a plane, main The pivot pin vertical with mainboard is fixed at the both ends of plate respectively, and the pivot pin outer edge bulge part at both ends is respectively inserted in the rotation of cuboid In block, each pivot pin is allow to be rotated in spill spin block, also stubborn respectively on every piece of spill spin block there are one fastening bolt, fastening bolts Inner end threaded post position can press closer on pivot pin outer edge bulge position, every piece of spill spin block is respectively fixed with V-shaped Hollow leg, is inserted with telescopic telescopic rod in the front and rear part of every hollow leg respectively, and on telescopic rod and every hollow It is separately provided for the knob of fixed length of telescopic bar on supporting leg, left and right pair has been extended through in upper folded sheet and lower folded sheet The fixation stay bolt of title, mainboard are embedded with and fix symmetrical inner thread sleeve in upper and lower two edges, make folded sheet respectively After being opened with lower folded sheet, the threaded rod of the fixation stay bolt of upper folded sheet and lower folded sheet can be inserted into corresponding inner screw sheath In cylinder.

The utility model realizes the folding of plate face and supporting leg, use easy to carry, and by the support of pivot pin with And fixation of the fastening bolt to pivot pin, so that mainboard angle is rotated adjusting, and can be fixed, opening state can be made in this way Plate face bigger, draw the finer and smoother caricature works of bigger convenient for painter；Mainboard, upper folded sheet, lower folded sheet after opening A plane is formed by fixed stay bolt, the plane formed in this way is not only convenient for folding, and after fixing more securely.

Specific implementation mode

As shown in Figs. 1-5, a kind of foldable adjustable angle caricature drawing boards, including mainboard 1 and be fixed on by hinge The upper folded sheet 2 of 1 lower edges of mainboard and lower folded sheet 3, and it is located at mainboard 1 after upper folded sheet 2 and the folding of lower folded sheet 3 Two sides, after so that folded sheet 2 and lower folded sheet 3 is opened, mainboard 1, upper folded sheet 2, lower folded sheet 3 form a plane, main The pivot pin 4 vertical with mainboard 1 is fixed at the both ends of plate 1 respectively, and the 4 outer edge bulge part of pivot pin at both ends is respectively inserted in cuboid In spill spin block 5, each pivot pin 4 is allow to be rotated in spill spin block 5, also stubborn respectively on every piece of spill spin block 5 there are one fastening bolts 6, the inner end threaded post position of fastening bolt 6 can press closer on 4 outer edge bulge position of pivot pin, and every piece of spill spin block 5 is fixed respectively There is the hollow leg 7 of a V-shaped, telescopic telescopic rod 8 is inserted with respectively in the front and rear part of every hollow leg 7, stretches The knob of 8 length of fixed telescopic rod, upper folded sheet 2 and lower folding are separately provided on bar 8 and on every hollow leg 7 Symmetrical fixed stay bolt 9 has been extended through in plate 3, is embedded with and is fixed symmetrical respectively in about 1 two edges of mainboard Inner thread sleeve 10, after so that folded sheet 2 and lower folded sheet 3 is opened, the fixation stay bolt 9 of upper folded sheet 2 and lower folded sheet 3 Threaded rod can be inserted into corresponding inner thread sleeve 10.

For the ease of carrying, upper folded sheet 2 and lower folded sheet 3 arbitrarily open and close when preventing from carrying, upper folded sheet 2 and lower folding Ring buckle 11, upper folded sheet 2 and lower 3 folding of folded sheet are rotatably connected to by hinge or shaft respectively in the left and right edges of lamination 3 When being stacked on the two sides of mainboard 1, the ring buckle 11 of upper folded sheet 2 and lower folded sheet 3 can be buckled in 1 or so corresponding lock nose of mainboard On 12.

In order to improve when fastening bolt 6 is tightened to 4 fixed firmness of pivot pin, the annular of 4 outer edge bulge part of pivot pin It is cased on face and the coarse drag ring 13 of face of weld, 13 rough surface of drag ring, carries minimum microcellular structure, it in this way can be with Increasing frictional force when fastening bolt 6 is contacted with drag ring 13, drag ring 13 is less susceptible to rotate when fastening bolt 6 is tightened, to Pivot pin 4, mainboard 1 are less susceptible to rotate, more stable convenient for plate face when caricature drawing.

Utility model works principle：In use, height as needed pulls out telescopic rod 8, the rotation on telescopic rod 8 is used in combination Button fixes its length, upper folded sheet 2 and lower folded sheet 3 is then opened, respectively by the fixation of upper folded sheet 2 and lower folded sheet 3 The threaded rod of stay bolt 9 is inserted into corresponding inner thread sleeve 10, and rotation mainboard 1 arrives suitable angle, is finally tightened each tight Fixing bolt 6, such as Fig. 2.

Ring buckle and lock nose actually form lock, and the production of ten thousand Jiang Zhicheng hardwares factory of Dongguan City may be used in lock Wine box is locked（Gold lock）.

The standardized element that the utility model uses can commercially, shaped piece according to specification and attached drawing Record can carry out customized, the specific connection type of each part is all made of bolt ripe in the prior art, rivet, weldering Equal conventional means are connect, machinery, part and equipment are all made of in the prior art, conventional model, if be related to not being described in detail Circuit, circuit connection is also using connection type conventional in the prior art, and this will not be detailed here.

Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in the essential scope of the utility model, variation, change, addition or the replacement made, all The scope of protection of the utility model should be belonged to.
