When the rubber water bag 7 is filled with water during processing, the rubber water bag 7 cannot be filled with water, when the folded backboard is tiled, the two clamping plates 16 are vertical through the contact of the ends corresponding to the torsion springs 17, the two ends of the rubber water bag 7 are also driven to be vertical, and the water in the rubber water bag 7 is concentrated in the middle of the rubber water bag 7;

no matter the ancient book is displayed or stored, firstly, the spine 1 is downwards inserted between the two clamping plates 16, in the process, the middle part of the rubber water bag 7 is downwards extruded by the bottom of the spine 1, water concentrated in the middle part of the rubber water bag 7 respectively flows to the two ends of the rubber water bag 7, at the moment, the two ends of the rubber water bag 7 gradually expand after being filled with water, the two ends of the rubber water bag 7 are butted against one side corresponding to the spine 1 after expanding to a certain degree, the spine 1 is finally clamped oppositely, meanwhile, each clamping plate 16 is overturned towards one side far away from the spine 1 due to the reaction force generated after the gradually expanded end of the rubber water bag 7 is butted against the spine 1, at the moment, each torsion spring 17 is slowly compressed to the limit by the overturning of the clamping plate 16, once the ancient book is lifted, the spine 1 is separated from the rubber water bag 7, and at the moment, the corresponding clamping plate 16 is driven to be inclined and reset to be vertical by the elasticity of each torsion spring 17;

the squeezing plates 8 are matched with the clamping plate 16 and used for limiting the expansion of the part of the rubber water bag 7 between the squeezing plates, so that once the water concentrated in the middle of the rubber water bag 7 is squeezed to two ends, the two ends of the rubber water bag 7 penetrate out of the narrow grooves 9 in the two squeezing plates 8 respectively, the two ends of the rubber water bag 7 can expand rapidly at the moment, the spine 1 is clamped, and the elastic connection between the squeezing plates 8 and the clamping plate 16 is used for preventing the part of the rubber water bag 7 between the squeezing plates 7 from being burst due to the limitation of the expansion.

Both ends of every stripper plate 8 all are equipped with a set of elastic connecting piece, and every elastic connecting piece of group all includes:

the sliding rods 18 are uniformly distributed on one side, facing the clamping plate 16, of the extrusion plate 8 along the width direction of the corresponding extrusion plate 8, the axial direction of each sliding rod 18 is perpendicular to the corresponding extrusion plate 8, one end of each sliding rod 18 is fixedly connected with the corresponding extrusion plate 8, the other end of each sliding rod 18 penetrates through the corresponding clamping plate 16, and the end part of the penetrating end of each sliding rod 18 is in a threaded shape;

the limiting nuts 19 are screwed on the thread parts of the corresponding sliding rods 18 in a one-to-one correspondence with the sliding rods 18;

the springs 20 are sleeved on the penetrating ends of the corresponding sliding rods 18 in a one-to-one correspondence manner with the sliding rods 18, and two ends of each spring 20 are respectively abutted against the corresponding limiting nut 19 and the corresponding clamping plate 16.

When the middle part of the rubber water bag 7 is squeezed, the water collected in the middle part of the rubber water bag 7 flows towards the two ends of the rubber water bag respectively, in the process, the part of the rubber water bag 7 between the clamping plate 16 and the pressing plate 8 has a tendency to expand, and at this time, the pressing plate 8 is interfered to move away from the clamping plate 16, each slide rod 18 is displaced together with the pressing plate 8, and after each slide rod 18 moves, the corresponding springs 20 are pressed against and compressed by the stop nuts 19 screwed on the screw portions of the sliding rods 18, and when the springs 20 are compressed to the limit, the corresponding squeeze plate 8 is displaced to the limit where the area between the squeeze plate 8 and the clamp plate 16 is expanded to the maximum, the portion of the rubber water bag 7 between the clamp plate 16 and the squeeze plate 8 is in the maximum expanded state, since the amount of water in the rubber-water bag 7 is constant, as the amount of water flowing to the rubber-water bag 7 between the clamping plate 16 and the squeezing plate 8 increases, the amount of water flowing to both ends of the rubber water bag 7 is reduced, so that the expansion degree of both ends of the rubber water bag 7 is reduced, the low expansion of both ends of the rubber water bag 7 is suitable for thicker ancient books, because the spine 1 of the ancient book with thicker thickness is thicker, once the two ends of the rubber water bag 7 are inflated by water, the two ends of the rubber water bag 7 will collide with the spine 1, and on the contrary, the high inflation of the two ends of the rubber water bag 7 is suitable for the ancient book with thinner thickness, therefore, the expansion degree of the two ends of the final rubber water bag 7 can be adjusted by changing the position of the limiting nut 19 on the sliding rod 18, and the shorter the spring 20 is compressed by the limiting nut 19 in the initial state, the less the water flows to the part of the rubber water bag 7 between the clamping plate 16 and the squeezing plate 8, the more the water flows to the two ends of the rubber water bag 7, so that the device can be suitable for clamping the book spines 1 of ancient books with different thicknesses.

The ancient book is loose in connection between the spine 1 and the pages due to long time, the spine clamping mechanism 5 in the device clamps the connection between the spine 1 and the pages while fixing the spine 1, so that the phenomenon that the connection between the pages and the spine 1 is broken after the ancient book is turned over is prevented, but if the ancient book is thick, the spine clamping mechanism 5 only can clamp the spine 1 and the pages below the spine 1, the pages above the spine can be broken when being connected with the spine 1, and the problems can be solved through two groups of cover bearing mechanisms 6;

because the preservation degree of each ancient book is inconsistent, some ancient books are better preserved, the connection between the spine 1 and the pages in such ancient books is tighter, both sides of the spine 1 are arched when the ancient books are unfolded, but some ancient books are not good preserved, which can lead the connection between the spine 1 and the pages to be looser, both sides of the spine 1 are flatter when the ancient books are unfolded, at the moment, the inclination angle of the corresponding moisture-absorbing sand bag 10 is changed through the wane 11, so that the moisture-absorbing sand bag 10 can be attached to the covers 2 in different states, so as to support both sides of the whole ancient books, the function of the wane 11 is similar to that of a seesaw in life, when the moisture-absorbing sand bag 10 is deflected to one side, sand in the moisture-absorbing sand bag 10 is deflected to one side of the moisture-absorbing sand bag 10, at the moisture-absorbing sand bag 10 is always in an inclined state through the wane 11, when the ancient books are not well preserved, one side of each moisture-absorbing sand bag 10 is deflected to one side away from the spine 1, so that the moisture-absorbing sand bag 10 is always in an inclined state, so that the moisture-absorbing sand bag 10 is kept in an inclined state, and the spine 1 is connected with the spine 1, when the ancient books are further loosened, the ancient books are prevented from the spine 1, and the spine 1, the pages are connected with the spine 1, and the spine 1, so that the ancient books are connected with the ancient books, and the ancient books are further connected with the spine 1, and the ancient books, when the ancient books are connected with the ancient books, and the ancient books, so that the ancient books are not loosened;

after deflecting about moisture absorption sand bag 10, the both ends of the wane 11 that corresponds all can contradict with the bottom of backplate, and the both ends of wane 11 and backplate all can be impaired in the past this long time, and then wrap the both ends of wane 11 through rubber strip 22, prevented the impaired of wane 11 and backplate.

Each moisture absorption sandbag 10 comprises a hard base 23 and breathable gauze 24, the breathable gauze 24 is sewn on the top of the hard base 23, a sealing cavity 25 used for containing sand is formed between the breathable gauze 24 and the hard base 23, the hard base 23 is parallel to the corresponding rocker 11, four pins 26 distributed in a matrix are fixedly arranged at the bottom of the hard base 23, four elastic inserting plates 27 corresponding to the pins 26 in a one-to-one mode are formed at the top of each rocker 11, each elastic inserting plate 27 is parallel to the rocker 11, and horizontal inserting grooves 28 used for enabling the corresponding pins 26 to be transversely inserted are formed in the same sides of the four elastic inserting plates 27.

The moisture absorption sandbag 10 has a moisture absorption function, after a period of time, the moisture absorption sandbag 10 needs to be replaced due to moisture absorption saturation of sand in the moisture absorption sandbag, and in order to facilitate replacement of the moisture absorption sandbag 10, the moisture absorption sandbag 10 needs to be detachably connected with the rocker 11;

when the moisture absorption sandbag 10 is installed, the four pins 26 are aligned to the four horizontal slots 28, then the moisture absorption sandbag 10 is pushed transversely, so that the four pins 26 slide into the four horizontal slots 28 respectively, finally the pins 26 are tightly pressed through the elasticity of the elastic inserting plates 27, and the same principle is carried out when the moisture absorption sandbag 10 is disassembled;

the sealed cavity 25 can also be filled with other particles with moisture absorption function, such as activated carbon particles and the like.

Each wide plate 14 is provided with a weight-reducing through hole 29.

The weight reduction through holes 29 are used for reducing the overall weight of the folding back support 4, so that the folding back support 4 is lighter to use, and when ancient books are stored, the cover 2 of the ancient books can be seen through the weight reduction through holes 29, and therefore the preservation degree of the ancient book cover 2 can be observed.

Each sliding rod 18 is provided with a shaft sleeve 30 for reducing friction between the sliding rod 18 and the clamping plate 16 at a position where the sliding rod 18 passes through the corresponding clamping plate 16.

The displacement of the pressing plate 8 will cause the corresponding sliding rod 18 to slide in the clamping plate 16, so that the sliding friction between the sliding rod 18 and the clamping plate 16 is reduced by the bushing 30.

The rubber water bag 7 comprises an elastic rubber ring 31 and two hard seals 32 for sealing the opening of the elastic rubber ring 31.

When the rubber water bag 7 is squeezed, the elastic rubber ring 31 is squeezed by water to deform, and the hard seal 32 does not deform, so that after the middle part of the rubber water bag 7 is squeezed downwards by the spine 1, water flows towards two end parts of the rubber water bag 7 in a concentrated manner, and finally the two end parts of the rubber water bag 7 are expanded greatly.

A use method of an ancient book back protection structure comprises the following steps:
