[0024] like Figures 1 to 4 As shown, the utility model provides a support frame for outdoor field painting, comprising a main frame 1 and a drawing board body 2, wherein a secondary frame 7 is movably connected to the interior of the main frame 1, and two left and right limit assemblies 3 are provided on the front of the main frame 1 and located on the back of the drawing board body 2, and an adjustment assembly 4 is movably installed at the lower end of the drawing board body 2, and the drawing board body 2 is connected to the main frame 1 through the adjustment assembly 4 and the limit assembly 3;

[0025] The limiting assembly 3 includes a slot 31 formed on the surface of the main bracket 1. A sliding clamping block 32 is movably connected to the interior of the slot 31. The cross-sections of the slot 31 and the sliding clamping block 32 are both "L"-shaped. The sliding clamping block 32 slides along the interior of the slot 31. Due to the arrangement of the adjustment assembly 4, the user can adjust the height of the drawing board body 2 in front of the bracket in cooperation with the limiting assembly 3. Moreover, the drawing board body 2 can be adjusted to any height connected to the slot 31 and fixed in place in cooperation with the sliding clamping block 32, which greatly facilitates operation and facilitates timely fixation after adjustment.

[0026] The adjustment component 4 includes two left and right linkage blocks 41 that are slidably connected to the back of the drawing board body 2. The rear ends of the two linkage blocks 41 are fixedly connected to the left and right sliding blocks 32 respectively. The internal threads of the two linkage blocks 41 are sleeved with adjustment screws 42. Both ends of the adjustment screws 42 pass through the linkage blocks 41 and extend to the left and right sides of the drawing board body 2 and are fixedly connected with a first adjustment knob 43. Due to the setting of the two left and right first adjustment knobs 43, the user can operate with either hand, avoiding the trouble caused by either hand being occupied and unable to adjust conveniently.

[0027] like Figure 3 As shown, the left and right slots 31 are symmetrical relative to the center line of the main bracket 1 , the width of the sliding clamping block 32 is smaller than the width of the slot 31 , and the sliding clamping block 32 always slides along the inside of the slot 31 .

[0028] like Figure 1 As shown, two upper and lower fixed magnetic strips 5 are embedded in the interior of the drawing board body 2, and two left and right movable magnetic strips 6 are placed on the front of the drawing board body 2. The upper and lower ends of the movable magnetic strip 6 are magnetically attracted to the upper and lower fixed magnetic strips 5 respectively; due to the setting of the upper and lower fixed magnetic strips 5, the two movable magnetic strips 6 can be firmly adsorbed on the surface of the drawing board body 2 with the cooperation of the left and right movable magnetic strips 6, thereby pressing the drawing paper, and can press any size of drawing paper that is not larger than the area of ​​the drawing board body 2, greatly improving the scope of application and convenience of use.

[0029] like Figure 4 As shown, the auxiliary bracket 7 includes an axial connecting rod 71 movably connected to the inside of the main bracket 1. The bottom of the axial connecting rod 71 is fixedly connected to a support rod 72. The internal sliding card of the support rod 72 is engaged with a limiting slider 73. The bottom of the limiting slider 73 is fixedly connected to a connecting slide rod 74. The lower end of the connecting slide rod 74 passes through the support rod 72 and is fixedly connected to a support plate 8. The bottom of the support plate 8 is fixedly connected to a number of fixed cones 9. By inserting the fixed cones 9 into the ground, the stability of the bracket during outdoor sketching can be further increased.

[0030] like Figure 4As shown, the cross-sections of the limiting slider 73 and the connecting slide rod 74 are both rectangular, the outer surfaces of the limiting slider 73 and the connecting slide rod 74 are adapted to the inner wall of the support rod 72, and the outer diameter of the limiting slider 73 is larger than the outer diameter of the connecting slide rod 74.

[0031] like Figure 4 When the handle 7 is in the closed position, the second stop 76 is fixed on the second stop 74, and the lock 7 is unlocked, so that the user can easily reset the lock 70. When the handle 7 is unlocked, the user can reset the lock 70. When the handle 7 is unlocked, the user can reset the lock 70.

[0032] The working principle and use process of this utility model:

[0033] After the main bracket 1 is placed on the ground, the support rod 72 is swung backward under the connection action of the shaft connecting rod 71 to swing the support plate 8 and the fixing cone 9 to the rear of the main bracket 1, so that they form a supporting structure at the lower end of the main bracket 1. Then, the second adjusting knob 76 is turned to drive the limiting slider 73 and the connecting slide rod 74 downward through the transmission screw 75 under the restriction of the support rod 72 on the limiting slider 73, thereby increasing the length of the auxiliary bracket 7, thereby adjusting the support angle, increasing the bottom support area, and improving the stability of the support. Inserting the fixing cone 9 into the ground can further increase the firmness of the supporting structure when used outdoors.

[0034] Then, by turning any one of the left and right first adjusting knobs 43, the left and right linkage blocks 41 can be moved away from each other through the adjusting screw 42, thereby making the two sliding clamping blocks 32 move away from each other along the inside of the clamping slot 31, so that the two sliding clamping blocks 32 and the clamping slot 31 can slide relative to each other. Then, after the drawing board body 2 is moved up and down until the required height is reached, any one of the first adjusting knobs 43 can be turned in the opposite direction to drive the two sliding clamping blocks 32 to move closer to each other along the inside of the clamping slot 31 through the adjusting screw 42 and the linkage block 41 and clamp the main bracket 1, so that the two sliding clamping blocks 32 can be kept fixed, thereby fixing the drawing board body 2 to the front side of the main bracket 1;

[0035] With the cooperation of the upper and lower fixed magnetic strips 5 and the left and right movable magnetic strips 6 , the user can conveniently press the laid drawing paper, and it is suitable for pressing any drawing paper that is not larger than the area of ​​the drawing board body 2 .
