[0020] 1. The present application uses a support seat including a support part as the center of gravity of the projection painting device, and arranges an offset part that is offset toward the front in the middle of the support part and a projection body that extends upward and tilted toward the front and is used to project toward the front side of the offset part, so that the projection painting device can be directly placed on the desktop, and the image projected by the projection body can be offset toward the front without setting a connecting structure on the desktop, so as to avoid the projected image being blocked by the support rod or the offset part and causing an incomplete image, so that the projection painting device can be applied to different types of desktops without being restricted by the connecting structure, thereby improving the adaptability of the projection painting device. At the same time, by setting the support rod that can be telescoped up and down The height of the projection body can be adjusted by lifting and lowering to adjust the distance by which the image projected by the projection body is offset toward the front side to adapt to desktops of different widths.

[0023] 4.

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:
[0034] refer to Figure 1-7 , a highly adaptable projection drawing device, comprising:
[0035] The support seat 1 has a side portion extending outward to form a support portion 12, and a middle portion extending upward to form an offset portion 11 offset to the front side, wherein a support rod 3 driven by a telescopic drive assembly 2 to extend and retract upward and downward is disposed in the offset portion 11; specifically, the support seat 1 is formed by buckling a front shell and a rear shell;
[0036] A support leg 4, one end of which is movably connected to the support portion 12 and the other end of which is extended forward;
[0037] The projection body 5 is detachably mounted on the support rod 3 . The projection body 5 is arranged to extend upward and obliquely toward the front side and is used for projecting toward the front side of the offset portion 11 .
[0038] The above-mentioned structure is set up, by using the support base 1 including the support part 12 as the center of gravity of the projection painting device, the offset part 11 offset toward the front side of the middle part of the support part 12, and the projection body 5 extending upward and tilted toward the front side and used for projecting toward the front side of the offset part 11, so that the projection painting device can be directly placed on the desktop, and the image projected by the projection body 5 can be offset toward the front side without setting a connecting structure on the desktop, so as to avoid the projected image being blocked by the support rod 3 or the offset part 11 and causing the image to be incomplete, so that the projection painting device can be applied to different types of desktops without being restricted by the connecting structure, thereby improving the adaptability of the projection painting device. At the same time, the support rod 3 is extended upward and downward. The arrangement makes it possible to adjust the height of the projection body 5 by lifting and lowering, so as to adjust the distance by which the image projected by the projection body 5 is offset toward the front side to adapt to desktops of different widths. On this basis, in order to improve the stability of the projection painting device and prevent it from tipping forward, a support leg 4 is movably connected to the support portion 12, and one end of the support leg 4 is extended forward, so that a spatial Z-shaped support is formed among the support leg 4, the support portion 12 and the offset portion 11, thereby avoiding the tipping of the offset portion 11 and improving the stability of the projection painting device. Moreover, the support leg 4 is arranged on the side, which not only does not affect the image projected by the projection body 5, but also has the function of pressing the drawing paper, thereby further improving the adaptability and functionality of the projection painting device.
[0039] In order to further improve the stability and convenience of the projection painting device, the number of the supporting parts 12 is set to two and they are respectively arranged on the left and right sides of the lower end of the offset part 11; the number of the supporting leg members 4 is set to two and they are respectively arranged on the left and right sides of the support seat 1; one end of the two supporting leg members 4 is respectively rotatably connected to the top of the two supporting parts 12, and the other end extends toward the far side and then folds in an arc shape and extends forward; the left and right sides of the offset part 11 and the corresponding top of the supporting part 12 are respectively connected in an arc shape to form a storage area 13 adapted to the two supporting leg members 4; when the support rod 3 is not extended upward to a high height, the projection painting device will not tip over, or when the projection painting device needs to be stored, the two supporting leg members 4 can be rotatably stored in the corresponding storage area 13. Thus, the support members 4 on both sides can form a double-sided spatial Z-shaped support with the two supporting parts 12 and the offset part 11, further improving the support stability of the projection body 5, so that the support rod 3 can be extended upward to a higher height to make the projected image of the projection body 5 move further forward. At the same time, by rotating and lowering the support members 4 on both sides, the two sides of the paper can be pressed respectively to act as a paperweight, which can prevent the paper from shifting or being blown away during the painting process, further improving the practicality of the support members 4, and when the support members 4 are not needed, they can be rotated and stored in the corresponding storage area 13, which improves the storage convenience of the support members 4, and can also reduce the space occupied by the entire projection painting device after being stored, thereby improving the overall practicality of the projection painting device.
[0040] In order to improve the stability of the support rod 3 in the upward and downward extension and retraction, a guide area 111 adapted to the support rod 3 is provided in the offset portion 11, and the telescopic drive assembly 2 includes a rotating shaft 21 that rotates laterally and passes through the offset portion 11, a gear 22 that is provided in the support seat 1 and is linked to the rotating shaft 21, and a knob 23 that is linked to the two outer ends of the rotating shaft 21. A driving rack 31 that meshes with the gear 22 is provided on one side of the support rod 3, and a yield groove 131 is provided in the front side recess of the two storage areas 13. The two knobs 23 are respectively provided in the two yield grooves 131. Specifically, the rotating knob 23 drives the support rod 3 to extend and retract up and down by rotating the gear 22 to engage the driving rack 31. The support rod 3 is thereby driven to extend and retract up and down through the meshing guidance of the gear 22 and the driving rack 31, and the upward and downward extension and retraction direction of the support rod 3 is restricted by the guide area 111, thereby improving the stability of the telescopic driving assembly 2 driving the support rod 3 to extend and retract up and down. At the same time, the setting of the clearance groove 131 allows the knob 23 to be embedded in order to avoid interference with the support leg 4, so that the support leg 4 can be stored and the telescopic driving assembly 2 can coexist at the same time, thereby improving the overall practicality of the projection painting device.
[0041] In order to further improve the stability of the support rod 3 in the upward and downward extension and retraction, a limit frame 112 located below the gear 22 and extending forward, and guide columns 113 fixed on both sides of the limit frame 112 are fixed on the rear side of the inner wall of the offset portion 11; a guide groove 1121 is recessed on the front side of the limit frame 112; a slider 1122 is slidably provided in the guide groove 1121 and slidably sleeved on the guide column 113 at both ends; a guide rack 32 is vertically extended on the other side of the support rod 3; a spring 114 for pushing the slider 1122 onto the guide rack 32 is provided between the slider 1122 and the inner wall of the offset portion 11; a guide tooth 1123 meshing with the guide rack 32 is protruded on the front of the slider 1122. Thus, by setting the guide tooth 1123 that engages with the guide rack 32 under the support of the spring 114, when the gear 22 rotates to engage the driving rack 31 to drive the support rod 3 to extend and retract up and down, the guide tooth 1123 can engage with the guide rack 32 step by step on the opposite side to play an up and down guiding role. At the same time, the front and back guidance of the gear 22 and the guide tooth 1123 can prevent the support rod 3 from deviating toward the front and back sides when extending and retracting up and down, thereby further improving the stability of the support rod 3 in extending and retracting up and down.
[0042] In order to further improve the stability of the support rod 3 in the upward and downward extension and retraction, the guide rack 32 protrudes from the rear side of the support rod 3 and its width is smaller than the width of the support rod 3. The driving rack 31 is recessed and arranged on the front side of the support rod 3. The front and rear inner walls of the offset portion 11 are fixed with a front guide frame 115 and a rear guide frame 116 located above the gear 22. The rear end of the front guide frame 115 and the front end of the rear guide frame 116 are oppositely recessed to form a leading guide area 1151 and a rear guide area 1161 respectively adapted to the outer wall of the support rod 3. The rear recess of the rear guide area 1161 and the middle part of the limiting frame 112 form a limiting area 117 adapted to the guide rack 32. The support rod 3 slides up and down in the guide area 111 including the leading guide area 1151 and the rear guide area 1161. The guide rack 32 slides up and down in the limiting area 117. In addition to guiding the support rod 3 to be extended and retracted up and down through the guide area 111 including the leading area 1151 and the rear guiding area 1161, the upward and downward extension and retraction of the guide rack 32 can be guided through the cooperation between the raised guide rack 32 and the limiting area 117, so as to improve the stability of the guiding engagement between the guide rack 32 and the guide tooth 1123. At the same time, it can also prevent the guide rack 32 from deviating to the left or right during the upward and downward extension and retraction process, thereby preventing the support rod 3 from deviating to the left or right, and further improving the stability of the upward and downward extension and retraction of the support rod 3.
[0043] In order to prevent the support rod 3 from extending upward excessively and disengaging from the offset portion 11, the lower end of the support rod 3 expands outward toward the front and rear sides to form a limiting portion 33 corresponding to the bottom of the front end of the gear 22 and the limiting frame 112 respectively, and the lower outer wall of the support rod 3 protrudes to form a limiting ridge 34 corresponding to the bottom of the front guide frame 115 and the rear guide frame 116, so that when the gear 22 rotates to engage the driving rack 31 to drive the support rod 3 to extend upward until the limiting portion 33 abuts against the limiting frame 112, and the limiting ridge 34 abuts against the bottom of the front guide frame 115 and the rear guide frame 116, it stops and cannot continue to rise.
[0044] In order to improve the stability of the projection body 5, a projection lens 51 is provided at the bottom of the front end of the projection body 5, a projection socket 52 connected to the projection lens 51 is horizontally penetrated through the lower part, a heat dissipation hole 53 connected to the projection socket 52 is opened on the top, and a power supply device is provided in the rear end. A projection lamp 54 corresponding to the projection lens 51 and electrically connected to the power supply device is installed in the heat dissipation hole 53 through a bracket 55. The projection socket 52 is used to insert a corresponding projection disk 6. Specifically, a film that can project an image, such as a film, is provided in the projection disk 6. A plurality of storage slots 14 that extend downward and tilt forward are recessed at the lower rear side of the support seat 1, and the plurality of storage slots 14 are used to store a plurality of the projection disks 6. Therefore, by arranging a heavier power supply device at the rear end of the projection body 5, the center of gravity is moved backward to prevent the front end of the projection body 5 from being too heavy and tipping forward, and placing projection structures such as the projection lens 51, the projection jack 52, and the projection lamp 54 at the front end of the projection body 5, it is further ensured that the image projected by the projection body 5 can be located in front of the offset part 11 to avoid being blocked by it, thereby improving the projection stability of the projection body 5. At the same time, by arranging a storage slot 14 on the rear side of the support base 1 for storing the projection disk 6, not only the storage function of the support base 1 can be increased and the practicality can be improved, but also the weight of the bottom of the support base 1 can be further increased, the center of gravity of the support base 1 can be moved backward, the risk of the offset part 11 tipping over can be reduced, and the support stability of the support base 1 can be improved.
[0045] In order to further improve the practicality of the support member 4, a cylindrical protrusion at the top of one end of the support member 4 forms a pen barrel portion 41, and the middle of the pen barrel portion 41 is concave to form a pen barrel groove 411 that penetrates and is inserted into the support portion 12. Therefore, the pen barrel groove 411 can be added to increase the function of storing watercolor pens, thereby improving the practicality of the support member 4, and further improving the functionality and practicality of the entire projection painting device.
