Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides an embodiment:

a drawing board with a clamping structure for art comprises a supporting frame 1, wherein a drawing board 3 is movably arranged on the right side of the supporting frame 1 through a rotating shaft, a first slot 4 is arranged on the front surface of the drawing board 3, first through grooves 5 are formed in the drawing board 3 on two sides of the inner wall of the first slot 4, second clamping plates 13 are slidably arranged in the two first through grooves 5, a placing plate 6 is fixedly arranged on the left side of each second clamping plate 13, a second through groove 7 is formed in the right side of the placing plate 6, the number of the second through grooves 7 is two, first spring rods 8 are fixedly arranged in the second through grooves 7, first clamping plates 9 are arranged at the right ends of the two first spring rods 8, rubber plates 10 are fixedly arranged on the left sides of the first clamping plates 9, the placing plates 6 are pulled outwards through handles for holding the left sides of the placing plates 6, the placing plates 6 drive the second clamping plates 13 to slide in the two first through grooves 5, so that the placing plates 6 are pulled out of the, at this moment, the handle on the first grip block 9 is held to the user's accessible and outwards stimulates, thereby it is tensile to drive the left first spring beam 8 of rubber slab 10 and warp, at this moment the user can be with the picture book that needs the copying, paper or photo are placed in rubber slab 10 and are placed between 6, stop when placing the completion back and to first grip block 9 application of force, thereby at this moment first spring beam 8 is because the release of the elastic potential energy that tensile storage drives rubber slab 10 and is close to placing 6, thereby with the article centre gripping, thereby the effectual application scope that has promoted this device, the effectual practicality that has increased this device.

The left side of rubber slab 10 and the right-hand member fixed connection of first spring beam 8, the front contact of the left side of rubber slab 10 and centre gripping thing when through the centre gripping because the characteristic coefficient of friction of rubber slab 10 is great, stability when consequently having promoted the centre gripping on the one hand, has protected the centre gripping thing to a certain extent in addition, and the effectual clamping-force that has reduced is too big to cause damage to the centre gripping thing to a certain extent.

A third through groove 11 is formed in the right side of the drawing board 3, a second spring rod 12 is fixedly installed inside the third through groove 11, a second clamping plate 13 is fixedly installed at the right end of the second spring rod 12, a transverse plate 2 is fixedly installed on the right side of the supporting frame 1, a cavity 14 is formed in the top end of the transverse plate 2, a second slot 15 is formed in the transverse plate 2 on one side of the inner wall of the cavity 14 and communicated with the cavity 14, a fourth through groove 16 is formed in the transverse plate 2 on the inner wall on the other side of the cavity 14, a tension spring 17 is fixedly installed in the fourth through groove 16, an inserting plate 18 is fixedly installed at one end, close to the second slot 15, of the tension spring 17, one end of the inserting plate 18 extends into the second slot 15, the inserting plate 18 is pulled inwards by holding a handle at the top end of the inserting plate 18, the inserting plate 18 is stressed to press the tension spring 17 and is contracted inwards, the inserting plate 18, thereby starting drawing.

The working principle is as follows: when the user uses, outwards pulling through holding second grip block 13, at this moment second grip block 13 can drive the left second spring beam 12 of second grip block 13 tensile, at this moment the user can place the used paper of drawing between the back of second grip block 13 and support frame 1, after placing the completion, stop to the application of force of second grip block 13, at this moment second spring beam 12 restores to the throne owing to the elastic potential energy release of tensile storage thereby drives second grip block 13 and is close to support frame 1 to with the paper centre gripping.

When a user draws a picture, the user can hold the handle on the left side of the placing plate 6 to pull outwards, at the moment, the placing plate 6 drives the second clamping plate 13 to slide in the two first through grooves 5, so that the placing plate 6 is pulled out from the first slot 4, at the moment, the user can hold the handle on the first clamping plate 9 to pull outwards, so that the first spring rod 8 on the left side of the rubber plate 10 is driven to deform and stretch, at the moment, the user can place a picture book, paper or a photo to be copied between the rubber plate 10 and the placing plate 6, after the placing is finished, the force application to the first clamping plate 9 is stopped, at the moment, the first spring rod 8 drives the rubber plate 10 to approach the placing plate 6 due to the release of elastic potential energy stored by stretching, so that an object is clamped, at the moment, the left side of the rubber plate 10 is in contact with the front side of the clamped object, and because the characteristic friction coefficient of the rubber plate 10 is, in addition, the clamping objects are protected to a certain extent, and the clamping force is effectively reduced to be overlarge, so that the clamping objects are damaged to a certain extent.

When a user finishes clamping paper and the like to start drawing, the user can hold a handle at the top end of the inserting plate 18 and pull the paper inwards, the inserting plate 18 is stressed to press the extension spring 17 and contract inwards, the inserting plate 18 no longer blocks the cavity 14, and the user can take out the drawing pen and the eraser stored in the cavity 14 to start drawing.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
