[0002] In the calligraphy and painting mounting process, after waxing the mounted vertical-axis calligraphy and paintings, the back of the mounted piece is evenly rubbed and polished by a rubbing stone. The main functions are to make the back of the mounted piece smooth and soft, so that the picture center is not rubbed when rolling up; at the same time, it forms a wax protective film on the back of the mounted piece, so that the calligraphy and painting hanging on the wall is not infiltrated by the moisture of the wall, and the calligraphy, painting and itself have the effects of removing moisture, preventing damp and preventing insects. After the calligraphy and painting are waxed and polished, it plays a certain role in protecting the cultural relics in terms of thickness, flatness and moisture-proof effect.

[0003] Usually, the traditional rubbing stone is a polished cobblestone, which is used to flatten the picture. In traditional picture mounting, a mounted calligraphy and painting must be waxed before installing the top and bottom rods, and must be polished with a rubbing stone after waxing. People hold the rubbing stone with both hands and rub it forcefully on the back of the painting, rubbing it over and over again, covering every part. The restored heavy-color and silk picture centers are extremely fragile, the cultural relics themselves are severely acidified and decayed. Since the traditional rubbing stone is made of natural, smooth and flat-bottomed cobblestones or agate stones, it is large and heavy. During the polishing process, the picture center may be damaged due to being unable to bear the weight of the rubbing stone itself or the rubbing stone being too heavy and inconvenient to operate, resulting in heavy pressure on the user's technique and strength, causing serious losses. Therefore, it is necessary to design a device that is convenient to use and meets the rubbing painting standards to solve the above problems. Summary of the Utility Model

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0028] Embodiment

[0029] In order to solve the technical problems existing in the prior art, as Figures 1-7 shown, the present utility model adopts the following technical solution: a multifunctional rubbing stone device for protecting the mounting and restoration of ancient calligraphy and paintings, including a main rubbing painting board 1 and a plurality of extended rubbing painting boards 2. The plurality of extended rubbing painting boards 2 are sequentially spliced around the main rubbing painting board 1 to expand its rubbing painting area;

[0030] The main rubbing painting board 1 includes a mounting bottom plate 11. The surface of the mounting bottom plate 11 is evenly provided with a plurality of hemispherical through holes 111. At the top of the mounting bottom plate 11 and corresponding to each hemispherical through hole 111, a rubbing bead mounting cylinder 12 is fixedly installed. A rubbing painting bead 3 is movably connected in the hemispherical through hole 111. The bottom of the rubbing painting bead 3 extends beyond the bottom of the mounting bottom plate 11. The upper part of the rubbing painting bead 3 is inside the rubbing bead mounting cylinder 12. The rubbing painting bead 3 is in close contact with the inner wall of the hemispherical through hole 111 through the rubbing bead mounting cylinder 12. Both opposite sides of the mounting bottom plate 11 are fixedly connected with lifting brackets 13. A supporting arc plate 14 is clamped between the two lifting brackets 13. The top of the supporting arc plate 14 is fixedly connected with an elastic binding band 15;

[0031] The structure of the extended rubbing painting board 2 is different from that of the main rubbing painting board 1 in that there are no lifting brackets 13, supporting arc plates 14, and elastic binding bands 15.

[0032] Specifically, as Figures 1-3 shown, the rubbing painting beads 3 are made of agate stone or cobblestone into circles with a diameter in the range of 10 - 13 mm. By putting them into the rubbing bead mounting cylinders 12, the rubbing painting beads 3 are positioned in the hemispherical through holes 111 of the mounting bottom plate 11 and are arranged close to the hole walls. A part of the bottom of the rubbing painting beads 3 leaks out from the bottom of the mounting bottom plate 11. Lifting brackets 13 are arranged on both sides of the mounting bottom plate 11, thus making room for the main rubbing painting board 1 to be spliced with each extended rubbing painting board 2, so as to quickly expand the area of the rubbing painting operation and realize the rubbing painting process for calligraphy and painting works of various size specifications through flexible splicing;

[0033] Meanwhile, due to the small size of the rubbing beads 3 and their production according to a unified standard, and their placement and control of the placement quantity through each rubbing bead installation cylinder, the weight of the device and the density of the rubbing points can be effectively and accurately controlled, so as to achieve the parameter values of the standard rubbing process. The user puts the hand on the support arc plate 14 and the elastic binding strap 15. The support arc plate 14 completely supports the palm area, and at the same time, the elastic binding strap 15 fixes the position of the device, facilitating the user to operate;

[0034] We made agate round beads with a diameter of about 10 - 13 mm as rubbing stones, which reduces the weight of the existing rubbing stones. Instead of traditional rubbing stones, we make full use of the spherical characteristics. After waxing, it is flattened on the backing paper to form a plane, and it is gently rolled back and forth regularly in a 360 - degree manner. The perfect combination of the bead and the wax softens the wax layer and gently integrates it into the paper fiber layer, playing a role in moisture resistance and mildew prevention. The smooth rolling and unrolling reduce the friction on the painting core during winding. In this way, the embarrassing situation encountered in rubbing and polishing in the restoration of ancient calligraphy and paintings with decayed grooves is solved, that is, the painting back is rubbed and polished completely and softly. The rubbing stone ball is in the palm, making full use of the spherical characteristics, and gently rubbing along the back of the painting axis regularly. The gloss of the rubbed painting back is soft, which can better highlight the natural gloss of the backing paper and effectively prevent mildew, playing a role in protecting the painting core.

[0035] In an embodiment of the present utility model, further, the rubbing bead installation cylinder 12 includes a cylinder body 124. The cylinder body 124 is a cylindrical hollow structure. The bottom of the cylinder body 124 is fixedly connected to the top of the installation base plate 11 and corresponds to the hemispherical through - hole 111. The top of the cylinder body 124 is threadedly connected with an end cover 121. The center of the bottom of the end cover 121 is fixedly connected to the top of the top - tight spring 122. The bottom of the top - tight spring 122 is fixedly connected to a positioning block 123. The bottom of the positioning block 123 is in close contact with the surface of the rubbing bead 3.

[0036] In an embodiment of the present utility model, further, an arc - shaped groove that fits the surface shape of the rubbing bead 3 is opened at the center of the bottom of the positioning block 123.

[0037] Specifically, such as Figure 4As shown, in order to ensure that the embossing bead 3 can always be in contact with the inner wall of the hemispherical through-hole 111 during the embossing process and always provide a certain pressure while leaking out of the bottom of the mounting base plate 11, after the embossing bead 3 falls into the hemispherical through-hole 111 from the cylinder body 124, the positioning block 123 fixed to the bottom of the end cap 121 by the pressing spring 122 is arranged close to the surface of the embossing bead 3. The embossing bead 3 is installed in the hemispherical through-hole 111 by screwing the end cap 121 and the cylinder body 124 together. At the same time, by controlling the screwing depth of the end cap 121 and the cylinder body 124, the compression amount of the pressing spring 122 is controlled to control the pressing force on the embossing bead 3, which helps to control the force of the embossing process. And by setting the embossing bead mounting cylinder 12, the distribution density of the pressure points is achieved by selectively placing or not placing the embossing bead 3, so as to achieve flexible adjustment.

[0038] In an embodiment of the present invention, further, the shape of the mounting base plate 11 is a regular polygon with an even number of sides.
