Automatic clamp for retractable display board

Abstract

The invention discloses an automatic clamp for a retractable display board. The automatic clamp comprises a main clamping plate and a cover pressing plate, the cover pressing plate and the main clamping plate are movably connected through a first hinge and a second hinge, a main sealing edge is arranged on the side, away from the cover pressing plate, of the main clamping plate, and a first sliding rail, a second sliding rail, a third sliding rail and a fourth sliding rail are arranged in the main clamping plate side by side; five groups of contraction fixing mechanisms are respectively arranged among the first sliding rail, the second sliding rail, the third sliding rail and the fourth sliding rail and are movably connected with the sliding rails, each contraction fixing mechanism comprises a first sliding pipe, a second sliding pipe, a pulley and a bridle, and the first sliding pipe and the second sliding pipe are arranged between the second sliding rail and the third sliding rail in parallel. and the first sliding pipe and the second sliding pipe carry out X-axis sliding through pulleys arranged at the two ends of the first sliding pipe and the two ends of the second sliding pipe, and the first sliding pipe and the second sliding pipe are connected through the bridle. The automatic clamp for the retractable display board is designed aiming at a plastic convex panel, adopts a form that the sliding rail is matched with the retractable mechanism, and is simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of metal processing equipment, and in particular relates to an automatic clamp for shrinking display boards. Background technique [0002] When the current plastic display board is in use, in order to store and display more products, it will adopt a multi-convex design. This design can place as many originals as possible in the notch of the plastic board, but due to the limitation of the plastic material, the design The strength of the plastic with the convex surface is greatly reduced, and it is easy to be damaged and cause losses during transportation. If the plastic is directly replaced by steel, iron and other materials, the cost will be greatly increased. Therefore, a solution is needed to solve the above problems. [0003] It should be noted that the above content belongs to the scope of the inventor's technical cognition and does not necessarily constitute the prior art. Contents of the invention ...
