Detailed Description

The novel easel as shown in the attached drawing comprises an easel body 1, a fixed rod 3 fixedly arranged on a base 2 in a penetrating way, an upper supporting component 4 arranged at the top of the fixed rod 3 and a lower supporting component 5 arranged at the bottom of the fixed rod, wherein the lower supporting component 5 comprises a mounting plate 6 arranged at the middle of the fixed rod 3 and below the fixed rod, and a large sleeve a7 hinged on the mounting plate 6, the telescopic small sleeve a8 that sets up in big sleeve a7, set up the U-shaped holding plate 9 at small sleeve a8 end, go up supporting component 4 including articulating big sleeve b10 that leans on dead lever 3 top, the telescopic small sleeve b11 that sets up in big sleeve b10, the tip of small sleeve b11 also is provided with a U-shaped holding plate 9, relative arrangement between two holding plates 9, be provided with the fixed part that the restriction is flexible and the swing on the lower support component 5, still be provided with balancing weight 12 on the supporting leg of easel body 1.

The present embodiment is the first embodiment, and provides the upper and lower support assemblies 5 capable of freely extending and retracting, and the drawing board can approach or depart from the user at a plurality of angles according to the needs of the user.

When the user needs to draw the drawing board forward, the fixing part for limiting the movement of the lower support assembly 5 is loosened, the drawing board is held and pulled, meanwhile, the drawing board can be adjusted to a proper angle, and then the fixing part is fixed again.

The fixing part can adopt any available mode, such as fixing bolt, etc., and because the mounting plate 6 is hinged with the fixing rod 3, the fixing bolt can not be used between the mounting plate 6 and the fixing rod 3, the ball bearing can be directly selected as the hinge part of the mounting plate 6, and because the ball bearing can be screwed and fixed, the problem can be solved together. The ball bearing can adopt the conventional design, fixes the axle sleeve of bearing on dead lever 3 to be connected the bulb through connecting rod and big sleeve a7, the bulb embolias the axle sleeve after, the knob on the axle sleeve is screwed alright fixed bulb, loosens the knob just rotatable bulb.

The large sleeve a7 is connected with the small sleeve a8 in a sliding manner, the small sleeve a8 is located in the large sleeve a7, and in order to prevent uncontrolled rotation when the small sleeve a8 is adjusted to stretch, the small sleeve a8 can be a square body, the shape of the large sleeve a7 is not limited, the large sleeve a7 can be a square body or a column body, and the space for the small sleeve a8 to stretch and slide is square.

Because upper and lower supporting component 5 all is articulated, probably there is certain bending between grip block 9 and the little sleeve when the swing, and drawing board itself can't be crooked, consequently when centre gripping drawing board swing, grip block 9 receives certain power of dragging, makes the life-span of grip block 9 receive the influence. In order to reduce the influence of the situation on the service life of the clamping plate 9, two schemes can be adopted, one scheme is that two U-shaped side walls of the clamping plate 9 are made of soft materials such as rubber; and the other is that the clamping plate 9 can freely swing to a certain extent by arranging the hinge piece between the clamping plate 9 and the small sleeve. If the clamping plate 9 adopts soft material, then can set up the clamping-force of strengthening rib in order to increase the centre gripping drawing board on the 9 outer walls of clamping plate, reduce because the drawing board is too heavy and lead to clamping plate 9 to warp, still can set up the coating that increases frictional force at the 9 inner walls of clamping plate.

It should be noted that the fixing rod 3 of the present embodiment corresponds to a screw adjusting rod of the prior art, which realizes the clamping of drawing boards with different heights by lifting, whereas the fixing rod 3 of the present embodiment is fixed on the base 2. If will realize the effect of the not high drawing board of centre gripping among the prior art in this embodiment, can pass through the threaded fixation with mounting panel 6 on dead lever 3, fix the high difference on dead lever 3 through mounting panel 6, realize that the distance between lower supporting component 5 and the last supporting component 4 is adjustable to the effect that realizes adapting to different size drawing boards, this is also that lower supporting component 5 sets up mounting panel 6, and goes up supporting component 4 and does not have the reason of mounting panel 6.

Because there is because of the topography reason, and the easel that leads to after stretching out has the unstable condition of balance, consequently can overlap on the supporting leg and be equipped with balancing weight 12, balancing weight 12 can set up in advance on keeping away from the rear supporting leg of drawing board, also can set up balancing weight 12 to the shape of clamp about similar, is in the same place and fixes on the supporting leg through threaded connection during the use. If the scheme that the balancing weight is preset is adopted, the balancing weight can be fixed on the supporting leg through the fixing bolt, and the bolt can be loosened when the balancing weight needs to be moved.

Preferably, the fixing part comprises a fan-shaped fixed disc 13 fixedly connected to one side of the mounting plate 6 and a limiting plate 14 arranged on the side wall of the large sleeve a7, the fixed disc 13, the large sleeve a7 and the small sleeve b11 are all provided with limiting holes 16, and the limiting plate 14 is provided with a limiting block 15 inserted into the limiting holes 16.

This embodiment is a first modification of the first embodiment, and provides a structure in which only one "member" is used to restrict the rotation of the mounting plate 6, and the telescopic sliding movement between the large and small sleeves is also restricted.

Specifically, the fixed plate 13 is arranged on the side face of the mounting plate 6, the limiting plate 14 is arranged on the large sleeve a7, and the limiting plate 14 is arranged opposite to the fixed plate 13, so that the size of the limiting plate 14 can be reduced, and the length of the limiting block 15 only needs to be properly prolonged.

When the device is used, the limiting plate 14 is rotated, and the limiting block 15 of the limiting plate 14 is inserted into the limiting block 15. The limiting holes 16 are distributed on the fixed disk 13 and the large and small sleeves, wherein the limiting holes 16 on the fixed disk 13 are distributed on the edge of the fixed disk 13 in a surrounding way, and the specific arrangement track of the limiting holes is determined by the swinging track of the large sleeve a 7. When the large sleeve a7 rotates around the mounting plate 6, the watch hand rotates on the dial plate, and after the large sleeve a7 finishes rotating, the rotation limiting plate 14 rotates upwards, so that the limiting block 15 is inserted into the limiting hole 16 on the fixed disk 13. To enable the stopper 15 to be more easily inserted into the stopper 15, the center of the fixed disk 13 may be coaxially arranged with the center point of rotation of the large sleeve a 7.

Meanwhile, the limiting block 15 is also inserted into the limiting hole 16 on the small sleeve a8 to realize fixation. The purpose of the large sleeve a7 also having the limiting hole 16 is that a part of the small sleeve a8 is still located in the large sleeve a7, so the limiting hole 16 on the large sleeve a7 can be a through hole for the limiting block 15 to pass through the large sleeve a7 and insert into the small sleeve a8, thereby improving the limiting effect.

Because there is no extra fixing measure between the limiting block 15 and the limiting hole 16, the limiting block 15 can be made of high friction material (such as silica gel), and the outer wall of the limiting block 15 is provided with a structure for improving resistance (such as raised grains or a structure similar to the barb-shaped teeth of carnivorous animal for engaging the hunting animals), so that the limiting block 15 is difficult to be separated from the limiting hole 16.

Preferably, the small sleeve a8 is further provided with an extension plate 17 at both sides of the end, and the holding plate 9 is hinged with the extension plate 17.

This embodiment is a second modification of the first embodiment, and the holding plate 9 can be folded and stored by the extension plate 17 hinged thereto. Can be folded forwards or backwards.
