It can be carried on a rack. of the train. In addition, when the present invention is in a state as shown in FIG. 2 , the seat plate 19 and the cushion 20 are turned over to provide a seating position for the student. The sliding sleeve 18 can be adjusted in height according to the needs of the artist, and after adjusting the height, the sliding sleeve 18 and the support rod can be locked with a pin. The seat plate 19 and sliding sleeve 18 are provided with limiting blocks so that they can withstand the weight of the student after the seat plate 19 is turned over.

Hereinafter, the operation process of each structure will be described in detail with reference to the integrated state of the desk and chair shown in FIG. 2 , the upright easel state shown in FIG. 11 , and the luggage storage state shown in FIG. 12 .

When the present invention is in the state shown in FIG. 2 , the outrigger mechanism is placed horizontally on the ground, and the plate frame 1 is parallel to the outrigger mechanism. At this time, the first gear 13 and the arc-shaped rack 12 start to mesh because the longitudinal outriggers 10 are on the ground and cannot rotate out of the longitudinal leg grooves 9 . That is, the second rotation shaft 11 and the third gear 15 thereon do not rotate. Accordingly, according to the transmission relationship of the fourth gear 16, the second gear 14, and the first gear 13, the leg mechanism and the first rotating shaft 3 rotate clockwise in the direction shown in FIG. . From the connection relationship between the first sheave 4 and the second sheave 5 under the premise that the leg mechanism does not rotate, it can be seen that the plate frame 1 is also locked in a clockwise direction and the painter can sit. Draw on cushion 20 and on frame 1 of the paint board. In this state, in order to further improve the support strength and safety, a positioning hole is drilled in the shaft seat 7 and the support rod, and the positional relationship between the support rod and the leg mechanism is shown as shown in FIG. Used to further lock the positional relationship between the leg mechanisms.

If a change is required from the state shown in FIG. 2 to the state shown in FIG. 11, the painter first turns the saddle plate 19 and the cushion 20 upside down close to the support, and then holds the support by hand and lifts it. The longitudinal leg grooves (9) are against the leg so that the longitudinal leg (10) loses its ground restraints as it rises as a whole, and the support rod rotates clockwise relative to the leg mechanism in the direction shown in Figure 2 (Fig. 2). The rotation of the support rod, the arc-shaped rack 12 is simultaneously rotated through the transmission of the first gear 13, the second gear 14, the fourth gear 16, and the third gear 15 to form the longitudinal leg 10 ) to move it outward. Longitudinal leg slot 9. Relative locking of the support rod with the leg mechanism is established until the horizontal leg 8 rotates until the bottom of the limiting baffle 17 cannot rotate. In this process, the drawing board frame 1 is also driven by the drawstring 6 and rotates in the state shown in FIG. 9, parallel to the leg length groove 9, and the rotated vertical leg 10 is the entire device . As shown in Fig. 21, in this state, the plate frame 1 is inclined with respect to the longitudinal leg 10, that is, it is inclined backward, and the longitudinal leg groove 9 is all located at the rear of the support bar. In the design of the hinge seat 2 , since the plate frame 1 is positioned in front of the support in this state, the distance between the student and the plate frame 1 is shortened, and the entire easel is steadily erected.

When it is necessary to change from the state shown in Fig. 2 to the state shown in Fig. 12, first turn the seat plate 19 and the cushion 20 close to the position of the support bar, then the longitudinal leg grooves 9 step on As shown in FIG. 2, the drawing board frame 1 rotates clockwise under the action of gravity to approach the supporting rod until the supporting rod rotates in the state shown in FIG. 12, as shown in FIG. rotate in the direction The arc-shaped rack 12 rotating counterclockwise is separated from the first gear 13 and does not affect the rotation and storage of the support rod and the plate frame 1 . The seat plate 19 and the seat cushion 20 are positioned between the longitudinal leg grooves 9 on both sides. The rear surface of the plate frame 1 is rotated upward of the limiting baffle 17 to form a relative horizontal position where the support rod, the plate frame 1, and the vertical leg grooves 9 sequentially overlap, thereby reducing the occupied space. By the entire device in a storage state. A locking device can be installed between the limiting baffle 17 and the rear surface of the drawing board frame 1 to ensure the stability of the device in the storage state to realize the relative fixation between the drawing board frame 1 and the supporting rod. When the position of the plate frame 1 and the support rod is locked once in the storage state, the support rod and the support leg mechanism are locked by the action of the pulling rope 6 .

If it is necessary to change the state shown in FIG. 12 to the state shown in FIG. 2 , step on the leg mechanism and turn away from the longitudinal leg groove 9 until the support rod rotates to the state shown in FIG. 2 . The angle between the support rod and the leg mechanism may be a right angle or an obtuse angle. When the angle is an obtuse angle, the arc-shaped rack 12 just meshes with the first gear 13 and locks each other. The support rod in the inclined state is more suitable for the artist to sit and draw, and it is not easy to reverse the rotation of the support rod in the use state, and the overall structure increases the stability.

Furthermore, because the height of the students is different, the height requirements of the drawing frame are also different, so the support can be designed as a telescopic rod structure. As shown in FIG. 1 , the support bar may be designed to include a first support bar 21 and a second support bar 22 superimposed on each other, where the second support bar 22 is located. The first support rod 21 may follow the first support rod. The longitudinal direction of the first support rod 21 is stretched and moved, the hinge base 2 is installed on the second support rod 22 , and the first rotation shaft 3 is located on the first support rod 21 bar.

When the length of the support rod is adjusted, the inner drawstring 6 is still driven in the cavity of the first support rod 21 and the second support rod 21 so that the drawing board frame 1 and the leg mechanism on both sides rotate at the same time can do. Support bar 22 As shown in FIG. 1 , a pull-rope subsequent tightening device is installed, and the lower part is fixedly connected to the first support bar 21 .

As shown in FIGS. 8 and 9 , the fifth gear 24 and the sixth gear 25 are mounted coaxially to the guide tube 23 . The fifth gear 24 and the sixth gear 25 have the same tooth pitch, but the number of teeth of the sixth gear 25 is half the number of teeth of the fifth gear 24 . The insertion post 26 is fixedly installed on the second support bar 22 , and the insertion post 26 is located above the guide tube 23 . The pin 26 is provided with a first straight rack 27 that meshes with the fifth gear 24 . The first straight rack 27 is positioned between the fifth gear 24 and the side wall of the guide tube 23 . The second straight rack 28 engaged with the sixth gear 25 is also installed on the guide tube 23 . The second straight rack 28 is positioned between the sixth gear 25 and the side wall of the guide tube 23 . The lower end of the second straight rack 28 extends out of the guide tube 23 and a movable pulley 29 is installed. A fixed pulley 30 is installed on the first rotating shaft 3 , and the fixed pulley 30 may rotate based on the first rotating shaft 3 . As shown in FIGS. 10 and 20 , one end of the draw rope 6 is fixed to the second sheave 5 . And the other end of the draw rope 6 first goes down under the fixed pulley 30 and then goes up to the movable pulley 29 and finally fixed to the first sheave 4 .

In the aforementioned pull-rope subsequent tightening device, the pull rope 6 between the second sheave 5 and the first sheave 4 is basically tightened when the first support rod 21 and the second support rod 22 are relatively moved. A state in which it can always be guaranteed that A leg mechanism fixedly connected to the first sheave (4) and fixedly connected to the drawing board frame (1) of the second sheave (5) so as to be able to rotate simultaneously under the restraint of the drawstring (6). As shown in FIG. 8 , the drawstring 6 is in a tensioned state, and when the second support bar 22 needs to be lifted vertically with respect to the first support bar 21 , the insertion post 26 of the second support bar 22 . ) drives the first straight rack. When the first straight rack 27 rises at the same time, the rising first straight rack 27 drives the fifth gear 24 to rotate clockwise, and the coaxially arranged sixth gear 25 also rotates clockwise. However, this is because the number of teeth of the sixth gear 25 is the number of teeth of the fifth gear 24, and on the premise that the fifth gear 24 and the sixth gear 25 rotate at the same angle, the guide tube 23 ), the length of the second straight rack 28 descending with respect to is half of the ascending distance of the first straight rack 27, that is, the distance that the movable pulley 29 descends is the ascending distance of the second support rod 22 half The rise of the second support rod 22 simultaneously drives the rope 6 to move up and tighten, while the movable pulley 29 releases the rope 6 which is twice the length of the descent distance and the movable pulley 29 falls The distance is Exactly the second support rod 22 rises. Half the distance, the drawstring 6 is still in tension at this time, and the drawing board frame 1 and the outrigger mechanisms on both sides can rotate simultaneously. When the second support rod 22 retracts and moves relative to the first support rod 21 , the rope 6 can still be in tension through the transmission of the rope subsequent tensioning device. A locking pin may be installed on the first support rod 21 to secure a position between the first support rod 21 and the second support rod 22 after expansion and contraction adjustment, and the second support rod 22 has a length It is opened and locked along the Several locking holes coincide with the pins, and the locking pins and locking holes coincide and lock.

Furthermore, in order to secure the lifting stability of the movable pulley 29 when the sixth gear 25 moves the second straight rack 28 up and down, a limit block ( 31) is installed. 23 The limit position block 31 is located on both sides of the second straight rack 28, and the setting of the limit block 31 can effectively prevent the shaking of the second straight rack 28 during vertical movement.

Furthermore, in order to make it easy to fix the plate required for drawing to the plate stand 1, it is possible to adjust and position the plate according to various sizes of the plate. As shown in FIG. 1 , a telescopic pole 32 is mounted on the plate plate FIG. 1 . A horizontally disposed upper frame 33 is installed on the upper portion of the vertical rod 32 , and the upper frame 33 is provided with a limit slot 34 , and the limit slot 34 matches the upper frame. the edge of the drawing board. Limiting holes 35 are also provided on both sides of the bottom of the plate frame 1, and limiting pins or brushes can be inserted into the limiting holes 35 to realize support of the bottom edge of the plate. The constraint slot 34 and the position of the pin or brush in the constraint position are really firm.

Furthermore, in the state shown in FIG. 2 , a positioning bolt 36 is installed as shown in FIG. 13 to facilitate adjustment of the height of the seat plate 19 and the seat cushion 20 according to the painter's drawing. . The support rods on both sides of the sliding sleeve 18 are provided with a number of positioning holes 37 that cooperate with the positioning bolts 36 . The positioning bolt 36, the positioning hole 37, the seat plate 19, the cushion 20, and the support bar can be relatively fixed.

When the present invention is in the painting state as shown in FIG. 11 , it is possible to effectively prevent paint or coloring in order to realize the height and angle adjustment of the plate frame 1 without the need for the painter to touch the drawing frame. Contaminate the picture frame and check that the picture is proceeding normally. Each clamping mechanism set includes a T-shaped groove 38 open to the drawing board frame 1 , a T-shaped slider 39 fitted into the T-shaped groove 38 , and one end of the T-shaped groove 38 . The slider 39 protruding from the T-groove 38 is provided with clamping. The tension spring 41 is connected to one end of the T-shaped slider 39 in the T-shaped groove 38 . The tension spring 41 tends to clamp the drawing board by always approaching each other because the clamping plate 40 is in close contact with the drawing board frame 1 , that is, the upper and lower ends of the clamping plate 40 .

To meet the market needs of advanced users, the painting frame is equipped with an intelligent adjustment mechanism, and the specific design approach is as follows. The pan/tilt 43 is passed through the upper clamping plate 40 and a motion detection camera 44 is installed. The support rod is a telescopic tube that is raised and lowered by the drive motor to realize the vertical elevation of the drawing board frame.

1. As shown in Fig. 16, when the drawing board frame 1 and the hinge base 2 are also adjusted to the hinged angle of the mounting rotation plate 45, the electric push rod ( 46) is placed.

2. The piston rod of the electric push rod 46 can adjust the angle between the drawing board frame 1 and the hinge base 2. The adjustment is about ±10 degrees to meet the different angle requirements of the painting process and realize a little adjustment. Angle. The motion detection camera 44 , the distance sensor 42 , the pan-tilt 43 , the drive motor and the electric push rod 46 are all electrically connected to each other through a control circuit.

The distance sensor 42 may detect a distance to the painter, and the somatosensory camera 44 may detect various control gestures of the painter. Both the driving motor and the electric push rod 46 are in a non-operational state, and the height and angular position of the drawing board frame 1 are fixed and not changed to ensure normal painting progress. If the drawing board frame 1 needs to be adjusted during the drawing process, the painter must be at a certain distance from the drawing frame, and the distance sensor 42 detects that the speaker is far away from the drawing board frame 1 and does not paint, and a motion detection camera 44 ) to recognize the painter's control gesture, and to control the operation of the driving motor and the electric pusher 46 in this way, the height and angular position of the plate frame 1 can be adjusted. On the premise that the painter does not touch the picture frame, the pan/tilt 43 is equipped with a motor. Setting the pan/tilt 43 allows the motion detection camera 44 to adjust its position according to the person capture algorithm. The motion sensing camera 44 controls the rotation of the pan/tilt 43 .
