[0007] The support mechanism includes a first rotating shaft. The first rotating shaft is rotatably installed on one side of the side plate away from the placement box through a bearing. The end of the first rotating shaft is fixed with a first support plate. A through hole is opened on the first support plate. A bolt penetrates through the inside of the through hole, and the end of the bolt is located inside a first limiting hole. The first limiting hole is opened on one side of the side plate. A second limiting hole is opened on one side of the side plate below the first limiting hole;

[0008] An adjusting mechanism is arranged on the first support plate.

[0009] Preferably, the adjusting mechanism includes a sliding groove. A sliding groove is opened inside the first support plate. The bottom of the sliding groove is rotatably installed with a second rotating shaft through a bearing. A second support plate is nested outside the second rotating shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a crankshaft placement rack, including a bottom plate 1, both sides of the top of the bottom plate 1 are fixedly provided with side plates 2, a placement box 3 is fixedly arranged between the side plates 2, and a support mechanism is arranged at one side of the side plate 2 away from the placement box 3;

[0023] The support mechanism includes a first rotating shaft 4. One side of the side plate 2 away from the placement box 3 is rotatably installed with the first rotating shaft 4 through a bearing. The end of the first rotating shaft 4 is fixedly provided with a first support plate 5. A through hole 6 is opened on the first support plate 5. A bolt 7 penetrates through the inside of the through hole 6. The end of the bolt 7 is located inside a first limit hole 8. The first limit hole 8 is opened on one side of the side plate 2. A second limit hole 9 is opened on one side of the side plate 2 below the first limit hole 8. The bolt 7 is slidably connected with the through hole 6, and the end of the bolt 7 is threadedly connected with both the first limit hole 8 and the second limit hole 9. Moreover, the central distances from the centers of the first limit hole 8 and the second limit hole 9 to the center of the first rotating shaft 4 are equal, ensuring that after the first support plate 5 rotates through the first rotating shaft 4, the end of the bolt 7 on the first support plate 5 can be aligned with the second limit hole 9, so that the end of the bolt 7 can be threaded inside the second limit hole 9, and the position of the first support plate 5 after rotation can be fixed;

[0024] An adjusting mechanism is arranged on the first support plate 5. The adjusting mechanism includes a sliding groove 10. A sliding groove 10 is opened inside the first support plate 5. The bottom of the sliding groove 10 is rotatably installed with a second rotating shaft 11 through a bearing. A second support plate 12 is nested on the outer side of the second rotating shaft 11. A first bevel gear 13 is fixedly arranged on the outer wall of the second rotating shaft 11 below the second support plate 12. A second bevel gear 15 is meshed with one side of the bottom of the first bevel gear 13. A third rotating shaft 14 is fixedly arranged in the middle of one side of the second bevel gear 15. The end of the third rotating shaft 14 penetrates through the side wall of the first support plate 5 and is fixedly provided with a handle 16. Moreover, the first support plate 5 is rotatably connected with the third rotating shaft 14 through a bearing. The second rotating shaft 11 is threadedly connected with the second support plate 12, and the second support plate 12 is in a snap-fit sliding connection with the sliding groove 10, ensuring that when the handle 16 is rotated forward or backward, the second support plate 12 can extend or shorten from the inside of the sliding groove 10, so that the end of the second support plate 12 can contact the ground.

[0025] The placement boxes 3 are evenly distributed between the side plates 2, increasing the number of crankshafts that can be placed inside the placement rack.

[0026] Working principle: When using this crankshaft placement rack, as Figure 1 shown, lean the rear side of the placement rack against the wall and rotate the bolt 7. Since the bolt 7 is threadedly connected to the first limit hole 8 and the bolt 7 is slidably connected to the through hole 6, the end of the bolt 7 is separated from the first limit hole 8. Then, reverse the first support plate 5 and the second support plate 12 through the first rotating shaft 4 until the end of the bolt 7 is aligned with the second limit hole 9. Rotate the bolt 7. Since the end of the bolt 7 is threadedly connected to the second limit hole 9, the thread of the end of the bolt 7 is inside the second limit hole 9, completing the fixation after the rotation of the first support plate 5 and the second support plate 12, so that Figure 2 the state becomes Figure 3 the state;

[0027] Then rotate the handle 16. At this time, the handle 16 drives the second rotating shaft 11 to rotate through the third rotating shaft 14, the second bevel gear 15 and the first bevel gear 13. Since the second rotating shaft 11 is threadedly connected to the second support plate 12 and the second support plate 12 is in a snap-fit sliding connection with the chute 10, the end of the second support plate 12 moves towards the ground until the end of the second support plate 12 contacts the ground, ensuring that when the ground is uneven, the end of the second support plate 12 can still contact the ground, improving the versatility of the placement rack. The first support plate 5 and the second support plate 12 play a supporting role for the crankshaft placement rack, increasing the floor area at the bottom of the crankshaft placement rack, reducing the probability of the crankshaft placement rack tipping over, playing a protective role for the workers, and improving the safety of the crankshaft placement rack.

[0028] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
