[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0021] Reference Figures 1-4 An adjustable inclined roller frame support structure includes a base 1. Two vertical plates 2 are bolted to the upper surface of the base 1 at its edge. A rotating plate 3 for mounting the roller frame is rotatably connected between the two vertical plates 2. The roller frame is based on prior art from the referenced prior art documents; the roller frame in this application is a reference to the prior art and will not be elaborated further here. Two end plates 4 are bolted to the upper surface of the base 1. Two sliding rods 5 are bolted between the two end plates 4. A slide frame 10 is slidably connected between the two sliding rods 5. Multiple fixing blocks 11 are welded to the top of the slide frame 10. A support rod 6 is rotatably connected between adjacent fixing blocks 11, and the support rod 6 is rotatably connected to the rotating plate 3. A wire is rotatably connected between the two end plates 4. The screw 9 passes through the slide 10 and is threadedly connected to the slide 10. One side of one end plate 4 is provided with a power component that drives the screw 9 to rotate. The screw 9 is driven to rotate by the power component. During the rotation, the screw 9 will move along the slide rod 5 by engaging with the slide 10 through the thread. When the slide 10 moves, it will pull the rotating plate 3 downward through the support rod 6. At the same time, the support rod 6 will rotate between the rotating plate 3 and the fixed block 11, so that the rotating plate 3 will tilt and change the inclination of the roller frame, which makes it easier for the staff to observe the welded workpiece. When the rotating plate 3 rotates downward to a certain angle, the screw 9 stops rotating. The position of the slide 10 is fixed by the thread engagement between the screw 9 and the slide 10.

[0022] In this utility model, the power component includes a self-locking motor 8, which is fixed to one side of one of the end plates 4 by bolts. One end of the output shaft of the self-locking motor 8 passes through the end plate 4 and is fixed to the lead screw 9. When the lead screw 9 needs to rotate, the self-locking motor 8 is started, and the self-locking motor 8 will drive the lead screw 9 to rotate. After the rotating plate 3 rotates downward to a certain angle, the self-locking motor 8 is turned off. At this time, the lead screw 9 no longer rotates. At the same time, the self-locking motor 8 has a self-locking function, so that the lead screw 9 no longer rotates, thereby ensuring the stability of the roller frame tilt adjustment.

[0023] Specifically, two vertical rods 7 are welded to the upper surface of the base 1. A second sliding groove 15 is provided on one side of each vertical rod 7 facing each other. A second slider 16 is slidably connected within the second sliding groove 15. First sliding grooves 12 are provided on both sides of the rotating plate 3. A first slider 13 is slidably connected within the first sliding groove 12. A connecting column 14 is rotatably connected to one side of the first slider 13 via a bearing, and the connecting column 14 is fixed to the second slider 16. The two vertical rods 7 are located on the upper surface of the base 1 away from the vertical plate 2, and are respectively located on both sides of the rotating plate 3. During the downward rotation of the rotating plate 3, the first slider 13 is moved, and the first slider 13, through the connecting column 14, causes the second slider 16 to move downward through the second sliding groove 15. The movement of the rotating plate 3 causes the first slider 13 to move within the first slide groove 12 and the connecting column 14 to rotate with the first slider 13. When the rotating plate 3 needs to be reset, it rotates upward, causing the second slider 16 to move upward within the second slide groove 15. When the second slider 16 moves to the top of the second slide groove 15, the rotating plate 3 is in a horizontal state, which allows for positioning and reset of the rotating plate 3, making it convenient for workers to reset the rotating plate 3. A guide rod 17 is fixed in the second slide groove 15 by bolts, and the guide rod 17 passes through the second slider 16. The guide rod 17 guides the movement of the second slider 16. Support legs are fixed at the four corners of the bottom of the base 1 by bolts.

[0024] Working principle: When in use, starting the self-locking motor 8 drives the lead screw 9 to rotate. During rotation, the lead screw 9 engages with the slide 10 via a thread, causing the slide 10 to move along the slide rod 5. As the slide 10 moves, it pulls the rotating plate 3 downwards via the support rod 6. Simultaneously, the support rod 6 rotates between the rotating plate 3 and the fixed block 11, causing the rotating plate 3 to tilt and change the inclination of the roller frame, facilitating observation of the welded workpiece. When the rotating plate 3 has rotated downwards to a certain angle, the self-locking motor 8 is turned off. At this point, the lead screw 9 stops rotating, thus fixing the position of the slide 10 through the thread engagement between the lead screw 9 and the slide 10. The self-locking motor 8 also has a self-locking function. The locking function prevents the lead screw 9 from rotating, thus ensuring the stability of the roller frame tilt adjustment. During the downward rotation of the rotating plate 3, the first slider 13 is moved. The first slider 13, through the connecting column 14, drives the second slider 16 to move downward in the second slide groove 15. At the same time, the first slider 13 moves within the first slide groove 12, causing the connecting column 14 to rotate with the first slider 13. When the rotating plate 3 needs to be reset, it is rotated upward. This causes the second slider 16 to move upward within the second slide groove 15. When the second slider 16 moves to the top of the second slide groove 15, the rotating plate 3 is in a horizontal state, thus allowing for positioning and reset of the rotating plate 3, facilitating the operator's reset of the rotating plate 3.

[0025] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
