DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0022] As Figures 1 to 5 shown, the utility model provides a kind of adjustable coating hanger, including support rod 1, the left and right sides of the top of support rod 1 are fixedly installed with vertical rod 2, the quantity of vertical rod 2 is two, the inner side of two vertical rods 2 is all set with sliding groove 3, sliding groove 3 is fixedly connected with cross bar 4 between two vertical rods 2, the bottom of cross bar 4 is fixedly connected with hook 11, the left and right sides of cross bar 4 are all fixedly connected with mounting block 5, the outer surface of mounting block 5 is movably connected with the inner surface of sliding groove 3, the front of two vertical rods 2 is all fixedly connected with U-shaped support 6, the right side of U-shaped support 6 inner chamber is fixedly connected with spring 7, the other end of spring 7 is fixedly connected with movable plate 8, the back of movable plate 8 is movably connected with the front of vertical rod 2, the outer surface of movable plate 8 is movably connected with the inner surface of U-shaped support 6, the front of movable plate 8 is fixedly connected with handle 9, the back of movable plate 8 is fixedly connected with bolt 10, the other end of bolt 10 is in order vertical rod 2 and mounting block 5 and extends to the inside of mounting block 5.
[0023] Pulling handle 9 outward will cause movable plate 8 to compress spring 7 and move pin 10 outward. When pin 10 moves to the outside of mounting block 5, it will release the fixing effect on mounting block 5. At this time, push crossbar 4 upward until mounting block 5 corresponds to pin 10. Then release handle 9. Under the elastic force of spring 7, pin 10 will reset and insert into the interior of mounting block 5 to fix crossbar 4, thereby achieving the purpose of adjusting the height of hook 11.
[0024] Among them, four round wheels 12 are movably installed around the bottom of the support rod 1. The four round wheels 12 are symmetrical about the center of the support rod 1.
[0025] The design of four wheels 12 allows the support rod 1 to move as a whole.
[0026] Among them, the outer sides of the two vertical rods 2 are fixedly connected to the fixing plates 13, the bottom of the fixing plates 13 are hinged to the rotating rods 14, the front of the rotating rods 14 is provided with a rectangular groove 15, and the inside of the rotating rods 14 is movably sleeved with the lifting rods 16.
[0027] The design of the rotating rod 14 and the lifting rod 16 improves the overall support stability of the painting fixture.
[0028] The rotating rod 14 is internally threaded with a first threaded rod 18, and the other end of the first threaded rod 18 passes through the lifting rod 16 and extends into the interior of the lifting rod 16.
[0029] The design of the first threaded rod 18 serves to fix the lifting rod 16.
[0030] The lifting rod 16 has a circular hole 17 inside, and the diameter of the circular hole 17 is the same as the diameter of the first threaded rod 18.
[0031] This design allows the first threaded rod 18 to be properly inserted into the round hole 17 to fix the lifting rod 16.
[0032] The top of the fixed plate 13 is fixedly connected to an L-shaped plate 19. The L-shaped plate 19 is internally threaded with a second threaded rod 20. The bottom of the second threaded rod 20 is movably sleeved with a lifting plate 21. The left and right sides of the bottom of the lifting plate 21 are hinged with connecting rods 22. The other end of the connecting rod 22 is hinged with a limit rod 23. The back of the limit rod 23 is fixedly connected to a cylindrical block 24. The outer surface of the cylindrical block 24 is movably connected to the inner surface of the rectangular groove 15.
[0033] Rotating the second threaded rod 20 downwards will cause the lifting plate 21 to move downwards, which in turn causes the two connecting rods 22 to rotate, causing the two limiting rods 23 to move in opposite directions. This causes the two cylindrical blocks 24 to move in opposite directions and squeeze, causing the two rotating rods 14 to rotate. At this time, rotating the first threaded rod 18 releases the fixing effect on the lifting rod 16, and then pulls the lifting rod 16 downwards until it contacts the ground. Subsequently, rotating the first threaded rod 18 resets it and inserts it into the round hole 17 to fix the lifting rod 16. This achieves the purpose of expanding the support area of the rotating rod 14 and improves the stability of the painting fixture.
[0034] The bottom of the fixing plate 13 is provided with a limiting groove 25, and the inner surface of the limiting groove 25 is movably connected to the outer surface of the limiting rod 23.
[0035] The design of the limiting groove 25 serves to limit the movement of the limiting rod 23, ensuring that the limiting rod 23 can move horizontally stably.
[0036] Working principle and usage process of this utility model:
[0037] When the length of the workpiece is greater than the distance between the upper and lower hooks 11, pulling the handle 9 outward will cause the movable plate 8 to compress the spring 7 and move the pin 10 outward. When the pin 10 moves to the outside of the mounting block 5, it will release the fixing effect on the mounting block 5. At this time, push the crossbar 4 upward until the mounting block 5 corresponds to the pin 10. Then release the handle 9. Due to the elasticity of the spring 7, the pin 10 will reset and insert into the interior of the mounting block 5 to fix the crossbar 4, thereby achieving the purpose of adjusting the height of the hook 11, which is convenient for painting the workpiece.
[0038] When the hook 11 is full of workpieces, the two second threaded rods 20 are rotated downwards, which will drive the two lifting plates 21 downwards. This will cause the four connecting rods 22 to rotate, which will drive the four limiting rods 23 to move in opposite directions. This will cause the four cylindrical blocks 24 to move in opposite directions and squeeze, causing the four rotating rods 14 to rotate. At this time, the first threaded rod 18 is rotated to release the fixing effect on the lifting rod 16. Then the lifting rod 16 is pulled downwards until it contacts the ground. Afterwards, the first threaded rod 18 is rotated back to its original position and inserted into the round hole 17 to fix the lifting rod 16. This achieves the purpose of expanding the support area of the four rotating rods 14 and improving the stability of the coating fixture.
