Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4This utility model provides an embodiment of a portable Thangka canvas anti-wrinkle support frame, including a first L-shaped bracket 1, a first adjusting bracket 2 at the top of the first L-shaped bracket 1, a second adjusting bracket 4 on the right side of the first L-shaped bracket 1, a second L-shaped bracket 3 at the top of the second adjusting bracket 4, a support rod 12 on the rear side of the first adjusting bracket 2 and the second L-shaped bracket 3 near the outside, a connecting block 7 fixedly connected to the bottom side of the first L-shaped bracket 1 and the second adjusting bracket 4 near the outside, a hinge block 8 hinged inside the connecting block 7, a support leg 5 fixedly connected to the bottom end of the hinge block 8, and an adjusting rod 9 fixedly connected to one side and one end of the first adjusting bracket 2 and the second adjusting bracket 4 respectively.
[0025] The second L-shaped bracket 3 is located on the right side of the first adjusting bracket 2. The adjusting rods 9 at the top and left side of the second adjusting bracket 4 slide at the bottom of the second L-shaped bracket 3 and the right side of the first L-shaped bracket 1, respectively. The adjusting rods 9 at the bottom and right side of the first adjusting bracket 2 slide at the top inside the first L-shaped bracket 1 and the left side inside the second L-shaped bracket 3, respectively.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the adjusting rod 9 on the first adjusting frame 2 is removed from the inside of the first L-shaped bracket 1 and the second L-shaped bracket 3, thereby allowing the first adjusting frame 2 and the second adjusting frame 4 to be disassembled, reducing the overall area of the support frame. Reducing the overall area makes it easier to carry the support frame. After reaching a suitable position, the adjusting rod 9 on the first adjusting frame 2 is inserted back into the inside of the first L-shaped bracket 1 and the second L-shaped bracket 3. The first L-shaped bracket 1, the first adjusting frame 2, the second L-shaped bracket 3, and the second adjusting frame 4 can then be assembled. Finally, the Thangka canvas is fixed in place by wrapping a fixing line around the support frame and the Thangka canvas.
[0027] The adjusting rod 9 has a fixing hole 14 inside, and a fixing bolt 13 is installed inside the fixing hole 14. The adjusting rod 9 is fixed inside the first L-shaped bracket 1 and the second L-shaped bracket 3 respectively by the fixing bolt 13 and the fixing hole 14. A winding hole 6 is provided on the right side inside the first L-shaped bracket 1. Multiple sets of fixing holes 14 are provided. The fixing holes 14 are arranged at equal intervals inside the adjusting rod 9. The adjusting rod 9 is located at the upper and lower ends inside the first L-shaped bracket 1 and the second L-shaped bracket 3.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, after inserting the adjusting rod 9 on the first adjusting frame 2 into the interior of the first L-shaped bracket 1 and the second L-shaped bracket 3, the fixing bolt 13 is screwed into the interior of the fixing hole 14 to fix the adjusting rod 9. When it is necessary to adjust the length and width of the support frame, the fixing bolt 13 is screwed out from the interior of the fixing hole 14, so that the first adjusting frame 2 and the second adjusting frame 4 are no longer fixed. Then, the adjusting rod 9 on the first adjusting frame 2 slides inside the first L-shaped bracket 1 and the second L-shaped bracket 3 to adjust the length and width, thus making it inconvenient for the support frame to limit and fix Thangka canvases of different sizes.
[0029] Mounting blocks 10 are fixedly connected to the rear ends of the first adjusting frame 2 and the second L-shaped bracket 3 near the outside. A protective shell 11 is fixedly connected to the rear end of the mounting block 10 near the outside. A worm gear 15 is movably connected to the front end inside the protective shell 11. A throttle 16 is fixedly connected to the top end of the worm gear 15. A rotating shaft 18 is movably connected between the mounting blocks 10. A worm wheel 17 is fixedly connected to the rear end of the rotating shaft 18 near the outside. The top end of the support rod 12 is fixedly connected to the outside of the rotating shaft 18. The worm wheel 17 is located inside the protective shell 11. The top end of the worm gear 15 penetrates the top end inside the protective shell 11. The worm gear 15 is located at the front end of the worm wheel 17. The worm gear 15 and the worm wheel 17 cooperate with each other.
[0030] Specifically, such as Figure 2 and Figure 3 As shown, the support rod 12 can support the rear end of the support frame. When the angle of the support rod 12 needs to be adjusted, the throttle 16 is turned. The throttle 16 drives the worm wheel 17 to rotate through the worm gear 15. The worm wheel 17 can then drive the support rod 12 to rotate through the rotating shaft 18 to adjust the angle of the support rod 12 and limit its support to the support frame. Adjusting the angle of the support rod 12 can control the angle of the support frame.
[0031] Working principle: In use, the adjusting rod 9 on the first adjusting frame 2 is removed from the inside of the first L-shaped bracket 1 and the second L-shaped bracket 3, allowing for the disassembly of the first adjusting frame 2 and the second adjusting frame 4. This reduces the overall area of the support frame, making it easier to carry. After reaching a suitable position, the adjusting rod 9 on the first adjusting frame 2 is reinserted into the inside of the first L-shaped bracket 1 and the second L-shaped bracket 3. The first L-shaped bracket 1, the first adjusting frame 2, the second L-shaped bracket 3, and the second adjusting frame 4 can then be assembled. After inserting the adjusting rod 9 on the first adjusting frame 2 into the inside of the first L-shaped bracket 1 and the second L-shaped bracket 3, the fixing bolt 13 is screwed into the fixing hole 14 to fix the adjusting rod 9. The length of the support frame needs to be adjusted. When adjusting the length and width, tighten the fixing bolt 13 again to unscrew it from the inside of the fixing hole 14, thus freeing the first adjusting frame 2 and the second adjusting frame 4 from their fixed positions. Then, slide the adjusting rod 9 on the first adjusting frame 2 inside the first L-shaped bracket 1 and the second L-shaped bracket 3 to adjust the length and width. After adjustment, use a fixing line to wrap around the support frame and the Thangka canvas to limit and fix the Thangka canvas. The support rod 12 can support the rear end of the support frame. When it is necessary to adjust the angle of the support rod 12, turn the handle 16. The handle 16 drives the worm wheel 17 to rotate through the worm gear 15. The worm wheel 17 can then drive the support rod 12 to rotate through the rotating shaft 18 to adjust the angle of the support rod 12 and limit its support on the support frame. Adjusting the angle of the support rod 12 can control the angle of the support frame.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
