[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 to Figure 4 : The automatic centering structure of the bracket includes a frame 1, a lifting rod 2, a supporting bracket 4 and a centering device 3. Specifically, refer to Figure 2 In the structure shown, a lifting rod 2 is arranged on a frame body 1, a centering device 3 is arranged on the lifting rod 2, a supporting frame 4 is connected to the centering device 3, the centering device 3 includes a bottom plate 31, a sliding plate 32, a sliding component 30 and an elastic component 33, the bottom plate 31 is connected to the lifting rod 2, the supporting frame 4 is connected to the outer side of the sliding plate 32, one end of the sliding plate 32 is connected to the bottom plate 31 through the sliding component 30, and the other end of the sliding plate 32 is connected to the bottom plate 31 through the elastic component 33.

[0019] The elastic component 33 includes a connecting seat 331, a connecting rod 332 and an elastic member 334. The connecting seats 331 are fixed on both sides of the bottom plate 31. The connecting seats 331 are provided with through holes 333. The connecting rods 332 are provided on both sides of the sliding plate 32 and are symmetrically arranged. The connecting rods 332 are sleeved with elastic members 334. One end of the elastic member 334 abuts against the connecting seat 331, and the other end abuts against the sliding plate 32. Preferably, the elastic member 334 is a spring, which is provided between the connecting seat 331 and the sliding plate 32, one end of the spring is connected to the sliding plate 32, and the other end of the spring is connected to the connecting seat 331. By providing the connecting rod 332, the spring can be guided by the connecting rod 332, so that the spring can be compressed and rebounded along the connecting rod 332.

[0020] The sliding plate 32 is provided with a mounting plate 38, which is arranged between the bottom plate 31 and the sliding plate 32. One end of the support bracket 4 passes through the sliding plate 32 and is connected to the mounting plate 38. The mounting plate 38 has connecting holes symmetrically arranged at both ends, and one end of the connecting rod 332 is fixed to the mounting plate 38 through the connecting holes. When the mounting plate 38 moves horizontally, it can simultaneously drive the connecting rod 332 to move horizontally, and can extend outward along the through hole 333, so as to facilitate the compression and rebound of the spring.

[0021] The sliding assembly 30 includes a first guide rail 34 and a first slider 35. The first guide rail 34 is fixed on the bottom plate 31. The sliding plate 32 includes a folding portion 321. Figure 2 As shown, the first slider 35 is fixed below the folding portion 321, and the first guide rail 34 cooperates with the first slider 35. When the first guide rail 34 and the first slider 35 cooperate, the folding portion 321 can slide horizontally along the first guide rail 34.

[0022] A second slide block 36 is connected to one side of the sliding plate 32 close to the bottom plate 31, and a second guide rail 37 is fixed on the bottom plate 31. Figure 3 As shown, the second guide rail 37 is horizontally arranged, the second slider 36 cooperates with the second guide rail 37, and the second guide rail 37 is arranged parallel to the first guide rail 34. The second slider 36 cooperates with the second guide rail 37, so that the second slider 36 can slide parallel to the second guide rail 37, so as to ensure that the sliding plate 32 can slide back smoothly under the action of the elastic component 33, and further ensure the automatic centering effect of the sliding plate 32.

[0023] Optionally, in order to further ensure the safety of the plate roller during movement, refer to Figure 3 A support frame structure is shown, in which a support groove 41 is provided at one end of the support frame 4 away from the sliding plate 32, and the support groove 41 is arc-shaped, and the opening of the arc-shaped support groove 41 is upward. In this way, when the support frame moves, the support frame moves to the right below the shafts at both ends of the shafted plate roller, and the arc-shaped support groove 41 matches the shaft of the plate roller, and can support the shafted plate roller upward, and confine one end of the shafted plate roller in the support groove 41, so that the shafted plate roller is more stable when moving. Therefore, by providing the support groove 41, the shafted plate roller can be effectively prevented from being separated when the moving frame moves forward and backward.

[0024] In actual use, when it is necessary to take the plate roller, one end of the plate roller is placed on the support groove 41. If the left and right ends of the sliding plate 32 are not horizontal, that is, one end is pressed and offset, the spring on the offset side will be compressed. For example, when the sliding plate 32 is pressed and offset to the left, the sliding plate 32 drives the connecting rod 332 to move to the left along the through hole 333. At the same time, the spring on the left is compressed. Under the action of the spring rebound force, the sliding plate 32 is pushed in the opposite direction of the offset, so that the sliding plate 32 moves to the right and returns to the center position, which has a return effect of lateral movement. When the plate roller is pulled up, the plate roller is centered under the action of the spring, thereby realizing automatic centering of the bracket. The overall structure is simple, the wear of the lifting rod on the offset is reduced, and the operating stability of the equipment is improved.

[0025] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
