Compared with the prior art, the reel structure 10 provided by the present application can rotate the second curved plate 300 in a direction away from the first curved plate 200 by rotating the cam 400, so that the first curved plate 200 and the second curved plate 300 are in a state where the material can be rolled up. After the rolling is completed, the second curved plate 300 can be rotated in a direction close to the first curved plate 200 by rotating the cam 400, that is, a gap is formed between the second curved plate 300 and the rolled material, so that the staff can quickly remove the material from the first curved plate 200 and the second curved plate 300, and the first curved plate 200 and the second curved plate 300 can be prevented from scratching the material.

[0024] In one embodiment, the base 100 includes a connecting shaft 110, a bottom plate 120 and a support column 130. The connecting shaft 110 and the support column 130 are both cylindrical and coaxially arranged. The bottom plate 120 is circular and is arranged between the connecting shaft 110 and the support column 130 and is respectively connected to the connecting shaft 110 and the support column 130. The connecting shaft 110 is used to connect to the output shaft of the driving member so that the driving member can drive the base 100 to rotate.

[0025] In one embodiment, the first curved plate 200 is fixed to a side of the bottom plate 120 away from the connecting shaft 110 by bolts, that is, the first curved plate 200 and the supporting column 130 are located on the same side of the bottom plate 120 .

[0026] In one embodiment, the first arc-shaped plate 200 and the second arc-shaped plate 300 each approximately occupy half of a cylinder. The second arc-shaped plate 300 and the first arc-shaped plate 200 are arranged in a ring shape and define an accommodation space 500 with the bottom plate 120. One side of the second arc-shaped plate 300 is rotatably mounted on the first arc-shaped plate 200 through a pin, and the other side of the second arc-shaped plate 300 is spaced from the first arc-shaped plate 200, thereby providing a reserved space for the rotation of the second arc-shaped plate 300. It should be noted that in other embodiments, the second arc-shaped plate 300 can also be rotatably mounted on the bottom plate 120 through a pin.

[0027] In one embodiment, the first arc-shaped plate 200 includes a first sub-arc-shaped piece 210 and a second sub-arc-shaped piece 220. The first sub-arc-shaped piece 210 is fixed to the bottom plate 120, and the second sub-arc-shaped piece 220 is rotatably mounted on one side of the first sub-arc-shaped piece 210 through a first pin 280. The second arc-shaped plate 300 is rotatably mounted on the side of the first sub-arc-shaped piece 210 away from the first sub-arc-shaped piece 210 through a second pin 290. The second arc-shaped plate 300, the first sub-arc-shaped piece 210, and the second sub-arc-shaped piece 220 are arranged in a ring shape and define an accommodation space 500 with the bottom plate 120. The cam 400 abuts against the sides of the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 away from the first sub-arc-shaped piece 210 and is rotatably mounted on the support column 130, so that the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 rotate in directions approaching or separating from each other. The side of the second sub-arc-shaped piece 220 away from the first sub-arc-shaped piece 210 is spaced relatively from the side of the second arc-shaped plate 300 away from the first sub-arc-shaped piece 210, thereby providing a reserved space for the rotation of the second sub-arc-shaped piece 220 and the second arc-shaped plate 300. It should be noted that in other embodiments, the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 can be respectively hinged to the first sub-arc-shaped piece 210.

[0028] In one embodiment, the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220, and the second arc-shaped plate 300 each approximately occupy one-third of a cylinder.

[0029] In one embodiment, the first sub-arc-shaped piece 210 includes a fixing portion 211 and a main body portion 212. The fixing portion 211 is sleeved on the support column 130 and fixed to the bottom plate 120 through bolts. The second sub-arc-shaped piece 220 and the second arc-shaped plate 300 are respectively rotatably mounted on the main body portion 212.

[0030] In one embodiment, a first convex column 310 is formed on a side of the second arc-shaped plate 300 away from the first sub-arc-shaped piece 210, a second convex column 221 is formed on a side of the second sub-arc-shaped piece 220 away from the first sub-arc-shaped piece 210, and the cam 400 is respectively in contact with the first convex column 310 and the second convex column 221. The provision of the first convex column 310 and the second convex column 221 can not only allow the second arc-shaped plate 300 and the second sub-arc-shaped piece 220 to rotate more widely, thereby increasing the gap between the material and the second arc-shaped plate 300 and the second sub-arc-shaped piece 220, making it easier to remove the material, but also reduce the size of the cam 400 and reduce the production cost.

[0031] In one embodiment, the cam 400 includes a body 410 and a lever 420. The body 410 is respectively abutted against the first convex column 310 and the second convex column 221 and is rotatably mounted on the support column 130. The lever 420 is connected to the body 410. The staff can shift the lever 420 to rotate the body 410 relative to the support column 130, so that the second sub-arc sheet 220 and the second arc plate 300 rotate in a direction of approaching or moving away from each other.

[0032] In one embodiment, the main body 410 is formed with a mounting hole 411 , and the support column 130 is formed with a mounting shaft 131 on one side away from the base plate 120 . The main body 410 is sleeved on the mounting shaft 131 through the mounting hole 411 , so that the main body 410 can rotate relative to the support column 130 .

[0033] In one embodiment, the main body 212 is formed with a first stopper 2121 and a second stopper 2122 in the accommodating space 500, the first stopper 2121 and the second stopper 2122 are arranged at intervals, and the lever 420 is arranged between the first stopper 2121 and the second stopper 2122. When the lever 420 rotates from the first stopper 2121 to the direction close to the second stopper 2122, the main body 410 is driven to rotate together, so that the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 rotate in a direction close to each other. When the lever 420 rotates from the second stopper 2122 to the direction close to the first stopper 2121, the main body 410 is driven to rotate together, so that the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 rotate in a direction away from each other.

[0034] In one embodiment, the reel structure 10 further includes an elastic member 600, one end of the elastic member 600 is connected to the second sub-arc sheet 220, and the other end of the elastic member 600 is connected to the second arc plate 300. When the lever 420 rotates from the first stop portion 2121 to the direction close to the second stop portion 2122, the elastic member 600 is in an inwardly retracted state. When the lever 420 rotates from the second stop portion 2122 to the direction close to the first stop portion 2121, the elastic member 600 is in an outwardly stretched state.

[0035] It should be noted that, in other embodiments, the roller structure 10 may also include a first magnetic member (not shown in the figure) and a second magnetic member (not shown in the figure), the first magnetic member is installed on the second arc plate 300, and the second magnetic member is installed on the second sub-arc plate 220, the first magnetic member and the second magnetic member are arranged opposite to each other, and the magnetic properties of the opposite end faces of the first magnetic member and the second magnetic member are different, so that the first magnetic member and the second magnetic member replace the elastic member 600.

[0036] In one embodiment, if Figure 3 As shown, the reel structure 10 further includes a first baffle 700 and a second baffle 800. The first baffle 700 is mounted on the bottom plate 120, and the second baffle 800 is disposed on a side of the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220, and the second arc-shaped plate 300 away from the bottom plate 120 and is detachably mounted on the mounting shaft 131 by screwing or clamping. The first baffle 700 and the second baffle 800 are disposed opposite to each other, so that the material is rolled up on the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220, and the second arc-shaped plate 300 between the first baffle 700 and the second baffle 800. When the rolled material needs to be removed, the second baffle 800 is first removed from the mounting shaft 131, and then the lever 420 is moved to drive the main body 410 to rotate, so that the second sub-arc sheet 220 and the second arc plate 300 rotate toward each other, so that a gap appears between the material and the second sub-arc sheet 220 and the second arc plate 300, so as to facilitate the quick removal of the material.

[0037] In one embodiment, the reel structure 10 further includes a sleeve 900, which is sleeved on a side of the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220, and the second arc-shaped plate 300 close to the bottom plate 120 and fixed to the bottom plate 120, so that the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220, and the second arc-shaped plate 300 can be more stably installed on the bottom plate 120. It can be understood that when the sleeve 900 is present, the first baffle 700 can be installed on a side of the outer periphery of the sleeve 900 away from the bottom plate 120.

[0038] The present application further provides a winding device, which includes a driving member and the drum structure 10 as described above. The output shaft of the driving member is connected to the connecting shaft 110 to drive the entire drum structure 10 to rotate, so that the first sub-arc-shaped piece 210, the second sub-arc-shaped piece 220 and the second arc-shaped plate 300 can wind materials such as cables or fabrics.

[0039] Compared with the prior art, the drum structure 10 provided by the present application can rotate the cam 400 to make the second arc-shaped plate 300 rotate away from the first arc-shaped plate 200, so that the first arc-shaped plate 200 and the second arc-shaped plate 300 are in a state where materials can be wound. After winding is completed, by rotating the cam 400 again, the second arc-shaped plate 300 can rotate towards the first arc-shaped plate 200, that is, a gap appears between the second arc-shaped plate 300 and the wound material, which facilitates the staff to quickly remove the material from the first arc-shaped plate 200 and the second arc-shaped plate 300, and can prevent the first arc-shaped plate 200 and the second arc-shaped plate 300 from scratching the material.
