The embodiment of the application discloses a clamping structure.

Referring to fig. 1, the clamping structure includes a supporting beam 1, a clamping portion 2 disposed on the supporting beam, and a fastening portion 3, the clamping portion 2 includes a first clamping plate 21 fixedly connected to the supporting beam 1, the supporting beam 1 is further rotatably connected to a second clamping plate 22, and the first clamping plate 21 and the second clamping plate 22 are disposed oppositely. The second clamping plates 22 are arranged in sequence along the length direction of the first clamping plate 21, and the edges of the clamping positions of two adjacent second clamping plates 22 are close to each other.

Referring to fig. 1 and 2, a plurality of connecting support plates 11 are fixedly connected to the supporting beam 1, a fixing rod 12 is commonly inserted into the connecting support plates 11, the fixing rod 12 is fixedly connected to the connecting support plates 11, a second clamping plate 22 is rotatably connected to the fixing rod 12, and the clamping position is a portion of the second clamping plate 22 away from the fixing rod 12.

Referring to fig. 1, a connecting ear plate 23 is fixedly connected to a side of the second clamping plate 22 away from the first clamping plate 21, and a metal sheet 24 is fixedly connected to the connecting ear plate 23.

Referring to fig. 2 and 3, first splint 21 slope sets up on supporting beam 1, and when the centre gripping canvas, the border position of canvas upwards turns up, owing to receive the spacing of picture frame, the difficult form that keeps upwards turning up of canvas, the first splint 21 and the second splint 22 that the slope set up more laminate the canvas and do not receive the state when pulling force, and the centre gripping effect is better.

Referring to fig. 3, first splint 21 or the one side rigid coupling that second splint 22 is in opposite directions have antiskid sheets 4, and antiskid sheets 4 can choose the gasket of polyurethane rubber material for use, and when first splint 21 and second splint 22 centre gripping canvas, antiskid sheets 4 can compress tightly the canvas and produce frictional force to can not harm the canvas when pressing from both sides tight canvas yet.

Referring to fig. 3, the abutting portion 3 includes an abutting cylinder 31 fixedly connected to the supporting beam 1 and an abutting piece 32 fixedly connected to an end of a piston rod of the abutting cylinder 31, and a piston rod of the abutting cylinder 31 faces an end surface of the second clamping plate 22, that is, the abutting piece 32 is disposed opposite to the metal sheet 24. After the edge position of the canvas is completely clamped between the first clamping plate 21 and the second clamping plate 22, the abutting cylinder 31 is started, the abutting cylinder 31 drives the abutting plate 32 to move, the abutting plate 32 can abut against the metal sheet 24 to compress the second clamping plate 22, and the clamping force between the first clamping plate 21 and the second clamping plate 22 can be ensured.

Referring to fig. 3, after the canvas is bound and is accomplished, in order to make canvas and first splint 21 and second splint 22 autosegregation, the butt piece 32 chooses the thin slice of magnet material for use, when closing to tight cylinder 31, the piston rod drives butt piece 32 and keeps away from second splint 22, because sheetmetal 24 and butt piece 32 laminate mutually, butt piece 32 can drive second splint 22 and upwards rotate an angle under the effect of magnetic force for the canvas breaks away from first splint 21 and second splint 22 automatically.

The positions of the abutting sheet 32 and the metal sheet 24 can be changed, that is, the magnet is fixed on the second clamping plate 22, and the abutting sheet is made of a metal material which is attracted with the magnet, so that a certain attraction force is generated between the end of the piston rod of the abutting cylinder 31 and the second clamping plate 22.

The implementation principle of a clamping structure in the embodiment of the application is as follows: in the process of binding the canvas, the canvas is arranged below the picture frame, the edge of the canvas exceeds the edge of the picture frame, the edge position of the canvas is turned upwards, and the canvas is sequentially placed between the first clamping plate 21 and the second clamping plate 22 along the sequence from one end to the other end.
