The utility model discloses a kind of flap mechanisms, including box, box cover, baffle, hinge, sheet metal support, spring steel wire and pulley;Box top is equipped with box cover, baffle is fixedly connected in box outer wall one end, hinge is located at baffle both ends, sheet metal support is fixedly installed in baffle one end, spring steel wire rotation is connected in sheet metal support lower side both ends, pulley rotation is connected in one end of spring steel wire.The utility model is compared with prior art's advantage lies in: the utility model utilizes the spring steel wire and the elasticity and torsional force of repeatedly contact cooperation between hinge to promote hinge, when hinge moves back, hinge profile promotes pulley movement, box cover is in open state at this time, the angle of opening and closing is locked by limiting screw and cam limiting boss between pulley and hinge simultaneously, it is convenient to open and close box cover stably, and the present mechanism does not need gas spring, service life is long, the stability when box door cover opens and closes is improved.

The utility model discloses an adjustable sheet metal part cutting clamp and belongs to the sheet metal machining technology. The adjustable sheet metal part cutting clamp comprises an operation table, the top end of the operation table is slidably connected with a movable plate, the top end of the movable plate is fixedly connected with an electric push rod, and the bottom end of the electric push rod is fixedly connected with a fixed plate. The opposite sides of the two movable plates are fixedly connected with supporting plates. According to the scheme, when the sheet metal parts are fixed, the two fixing plates and the two supporting plates are used for fixing the sheet metal parts, under the action of the adjusting mechanism, a worker can select the corresponding number of connecting plates to be connected with the supporting plates, and therefore the contact face when the sheet metal parts are supported is adjusted according to the sheet metal parts of different sizes, and the sheet metal parts are fixed conveniently. The use and utilization of the device are improved, when a large-size sheet metal part is supported, the multiple connecting plates and the supporting plate are selected to form a whole to support the sheet metal part, the supporting effect when the large-size sheet metal part is fixed is improved, and therefore the stability when the sheet metal part is fixed is enhanced.
