Adjustable artware fastening device

Abstract

The invention discloses an adjustable artware fastening device. The adjustable artware fastening device comprises a working groove, wherein two oppositely-arranged fixing plates are arranged in the working groove, each fixing plate comprises a vertically-arranged main plate and side plates vertically connected to the two ends of the main plate, the slide plates are slidably connected with the inner sidewall of the working groove, and a drive rod is connected to one side surface away from the side plates, of the main plate; and soft bags are arranged on the opposite wall surfaces of the two fixing plates, and the soft bags are internally filled with polyurethane particles. According to the fastening device disclosed by the invention, through the arrangement of the soft bags, the shapes of the soft bags can be deformed when the soft bags make contact with the surface of artware, the soft bags are internally filled with the polyurethane particles, so that the soft bags can be randomly deformed due to extrusion and completely bonded with the surface of artware, the surface of artware can be prevented from being worn, the artware is uniform in stress, and stress concentration at some parts in a fixing process is avoided; and flexible adjustment can be carried out according to the dimensions of the artware.

Description

technical field [0001] The invention relates to a fixing device, in particular to an adjustable handicraft fastening device. Background technique [0002] Handicraft is a handicraft product. It is a product of artistic value made by processing raw materials or semi-finished products by hand or machine. Handicrafts come from life, but they create a value higher than life. It is the crystallization of the wisdom of the people, fully embodies the creativity and artistry of mankind, and is a priceless treasure of mankind. Its main categories are wood, tooth, bamboo, carbon, jade carving, mahan glass, color carving, resin, Wenwan walnut, ceramics, paper-cut. In the process of production and processing of handicrafts such as jade carving, wood carving, mahan glass, color carving, resin, ceramics, etc., a whole piece of raw material is usually carved, shaped, and then polished, polished and Surface treatment, etc., and in these series of operations, it is necessary to place the...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the size of the object that can be fixed by the existing processing and fixing device is fixed, and at the same time, the surface of the object is not a smooth plane or arc surface, and there will be recessed or protruding parts, so When the object is fixed, the contact surface between the fixing device and the surface of the object is a protruding part. Not only is the area small, the stability of the fixation is poor, and the fastening force is too large to cause damage to the object. Adjustable handicraft fastening device, by setting the soft bag, the shape of the soft bag can be deformed when it is in contact with the surface of the handicraft. The complete fit can not only prevent the surface of the handicraft from being worn, but also the force of the handicraft is uniform, and will not cause stress concentration in some parts during the fixing process; at the same time, it can be flexibly adjusted according to the size of the handicraft, suitable for various fixation of objects
