As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, the embodiment of the utility model provides a drawing clamping device, including a drawing placement plate 1, two side plates 2 are fixedly installed on the upper surface of the drawing placement plate 1, and the two side plates 2 are symmetrically arranged. Two support seats 3 are fixedly installed on the lower surface of the drawing placement plate 1. Two clamping assemblies 4 are arranged on the upper surface of the drawing placement plate 1. The clamping assembly 4 includes a round rod 401, an arc-shaped pressure plate 402, a sleeve 403, a torsion spring 404, a rubber pad 405 and a rectangular plate 406. Two round rods 401 are fixedly connected between the two side plates 2. The outer sides of the two round rods 401 are movably sleeved with sleeves 403, and the outer sides of the round rods 401 are wound with torsion springs 404. The torsion springs 40 One end of 4 is fixedly connected to the inner wall of the sleeve 403, and the other end of the torsion spring 404 is fixedly connected to the outer side of the round rod 401. An arc-shaped pressure plate 402 is fixedly installed on the outer side of the sleeve 403, and a rectangular plate 406 is fixedly installed on the outer side of the arc-shaped pressure plate 402. The lower surface of the rubber pad 405 is in active contact with the upper surface of the drawing placement plate 1. A linkage component 5 is provided on the lower surface of the drawing placement plate 1. The linkage component 5 includes a U-shaped handle 501, a connecting rod 502, a movable plate 503, a guide hole 504, a spring 505 and a round plate 506. Guide wheels 7 are rotatably installed on the left and right sides of the drawing placement plate 1, and a connecting rope 6 is movably provided on the outer side of the guide wheel 7.

[0026] In one embodiment, a connecting rod 502 is fixedly installed on the lower surface of the drawing placement plate 1, and a circular plate 506 is fixedly connected to the bottom end of the connecting rod 502. A movable plate 503 is slidably arranged on the outer side of the connecting rod 502. A spring 505 is wound around the outer side of the connecting rod 502, and one end of the spring 505 is fixedly connected to the lower surface of the movable plate 503, and the other end of the spring 505 is fixedly connected to the upper surface of the circular plate 506. A U-shaped handle 501 is fixedly connected to the lower surface of the movable plate 503, so that the two connecting ropes 6 can be driven to move by pulling the connecting rod 502, thereby realizing the function of the two arc-shaped pressure plates 402 clamping the drawings at the same time.

[0027] In one embodiment, a guide hole 504 is provided on the upper surface of the movable plate 503 , and the inner wall of the guide hole 504 is fixedly connected to the outer side of the connecting rod 502 . The setting of the guide hole 504 makes it easy for the movable plate 503 to slide on the connecting rod 502 .

[0028] In one embodiment, one end of the connecting rope 6 is fixedly connected to one side of the rectangular plate 406, and the other end of the connecting rope 6 is fixedly connected to the upper surface of the movable plate 503. The connecting rope 6 is moved by the movable plate 503, so that the two rectangular plates 406 rotate simultaneously.

[0029] In one embodiment, a rubber pad 405 is fixedly attached to the lower surface of the arc-shaped pressing plate 402 , and the provision of the rubber pad 405 effectively avoids the phenomenon of the drawing being damaged.

[0030] In one embodiment, the torsion force of the torsion spring 404 is greater than the elastic force of the spring 505 , so that the rubber pad 405 can fit tightly against the drawing.

[0031] The utility model is in operation: when it is necessary to clamp the drawings, the U-shaped handle 501 is pulled downward, and the U-shaped handle 501 drives the movable plate 503 to slide downward along the connecting rod 502. When the movable plate 503 slides downward, the spring 505 is compressed, and the movable plate 503 slides downward to pull the two connecting ropes 6 to move downward under the action of the guide wheel 7. The two connecting ropes 6 respectively drive the corresponding rectangular plates 406 to rotate, and the rotating rectangular plates 406 drive the arc-shaped pressing plates 402 to rotate. When the arc-shaped pressing plates 402 rotate, the torsion springs 404 are twisted. At this time, the arc-shaped pressing plates 402 drive the rubber pads 405 to rotate upward and separate from the upper surface of the drawing placement plate 1. At this time, the drawings are spread on the upper surface of the drawing placement plate 1, and the pulling of the U-shaped handle 501 is released. At this time, the twisted torsion springs 404 are twisted. 04 reset, the torsion spring 404 drives the arc pressure plate 402 to rotate downward and reset, so that the rubber pad 405 contacts the upper surface of the drawing, and the arc pressure plate 402 rotates downward and drives the two rectangular plates 406 to rotate at the same time. The two rectangular plates 406 pull the corresponding connecting rope 6 to reset, and the spring 505 that is compressed is not reset when the U-shaped handle 501 is pulled, and the spring 505 drives the moving plate 503 to reset. Since the torsion force of the torsion spring 404 is greater than the elastic force of the spring 505, the arc pressure plate 402 and the rubber pad 405 are closely fitted to the upper surface of the drawing, so that it is easy to clamp and fix the drawing with two arc pressure plates 402 at the same time by pulling a U-shaped handle 501, and there is no need to clamp the drawing by rotating the screws in sequence, thereby improving the efficiency of clamping the drawing.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
