[0036] In the description of the present invention, it should be understood that the terms "first" and "second" are only used to simplify the description, and should not be understood as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" the first feature may include that the first feature is in direct contact with the second feature, or may include that the first feature and the second feature are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In order to solve the problem that the distance between the current book pressing device and the bracket is fixed, resulting in a limited use range of the book pressing device, the present invention provides a book pressing device, see Figures 1 to 8 As shown, the book pressing device includes a pressing rod 1 for pressing and fixing the opened book pages, and a pressing rod adjusting structure 2 for adjusting the pressing rod 1; wherein the pressing rod 1 is located in front of a bracket 3 for placing books, and the pressing rod adjusting structure 2 is connected to the rear side of the bracket 3; the front of the bracket 3 herein specifically refers to the side of the bracket 3 on which the books are placed; the pressing rod 1 is slidably connected to the pressing rod adjusting structure 2 along the front-to-back direction of the bracket 3, so that the position of the pressing rod 1 can be adjusted along the front-to-back direction of the bracket 3, thereby adjusting the distance between the pressing rod 1 and the bracket 3 through the pressing rod adjusting structure 2.

[0040] The bracket 3 in the present application can be any structure in the prior art that can support books; in order to facilitate clamping of books, the pressure rod 1 in the present application is distributed along the up and down directions of the bracket 3; specifically, the directions referred to by "up", "down", "front", "back", "left" and "right" in the present application refer to the directions indicated by the direction indicators in the accompanying drawings.

[0041] When using the book pressing device, firstly, the pressing rod 1 is adjusted in a direction away from the bracket 3 through the pressing rod adjusting structure 2, so that the distance between the pressing rod 1 and the bracket 3 is increased; the book is placed in front of the bracket 3, the pages are opened, and the opened pages are placed between the pressing rod 1 and the bracket 3, and then the pressing rod 1 is adjusted in a direction close to the bracket 3 through the pressing rod adjusting structure 2, so that the distance between the pressing rod 1 and the bracket 3 is reduced, until the pressing rod 1 clamps the opened pages to fix the book.

[0042] The book pressing device provided by the present invention is configured such that the pressing rod 1 is adjustable along the front-rear direction of the bracket 3, so that the distance between the pressing rod 1 and the bracket 3 can be adjusted, thereby enabling the book pressing device to clamp and fix books of any thickness, thereby expanding the use range of the book pressing device and improving the comfort of use.

[0043] Furthermore, in order to prevent the pressure rod 1 from causing damage to the book during the process of clamping the book, the present application preferably provides a silicone layer on the side of the pressure rod 1 close to the bracket 3, so that when the pressure rod 1 clamps the book pages, the silicone layer with a certain elasticity is in direct contact with the book pages, which on the one hand avoids damage to the book pages, and on the other hand, the friction between the pressure rod 1 and the book pages is increased or decreased by the silicone layer, thereby improving the stability of clamping the book pages.

[0044] To facilitate adjustment of the position of the pressure rod 1, see Figure 2 , Figure 3 As shown, the pressure rod adjustment structure 2 in the present application includes a shell 21, and a first adjustment structure 22 arranged in the shell 21; the upper and lower ends of the shell 21 are provided with first slide grooves 211 distributed along the front and rear directions of the bracket 3, and both ends of the pressure rod 1 are connected to the first adjustment structure 22 through the first slide grooves 211; the book pressing device also includes a switch structure (not shown in the figure), and the switch structure is connected to the first adjustment structure 22.

[0045] On the one hand, the shell 21 is used to protect the structure arranged inside it, and on the other hand, it improves the aesthetics and safety of the book pressing device; the present application is provided with a first slide groove 211 at the upper and lower ends of the shell 21, so that both ends of the pressure rod 1 can slide along the first slide groove 211, so that the distance between the two ends of the pressure rod 1 and the bracket 3 can be adjusted synchronously, and then the pressure rod 1 can clamp the opened book pages as a whole along the upper and lower directions, thereby improving the stability of clamping the opened book pages and preventing the opened book pages from being closed again.

[0046] The operation of the first adjustment structure 22 is controlled by setting a switch structure. During the operation of the first adjustment structure 22, the pressure rod 1 is driven to slide in the first slide groove 211 on the shell 21, so as to adjust the position of the pressure rod 1. The distance between the pressure rod 1 and the bracket 3 is adjusted by adjusting the position of the pressure rod 1.

[0047] Furthermore, the first slide groove 211 in the present application extends outwardly at one end close to the bracket 3, so that after the pressure rod 1 slides along the first slide groove 211 to one end close to the bracket 3, it continues to slide outward along the part extending outward on the first slide groove 211, and then the pressure rod 1 after extending outward can be flipped outward by a certain angle, which is convenient for the user to turn pages.

[0048] The first adjustment structure 22 in the present application includes a first connecting rod 221, an adjusting bolt 222, a stepper motor 223 and a control module, wherein the first connecting rod 221 is distributed in the up-down direction, and both ends of the first connecting rod 221 are connected to the pressure rod 1 through the first slide groove 211; specifically, the pressure rod 1 in the present application includes a pressure rod body 11 distributed in the up-down direction, and two second connecting rods 12 respectively connected to the two ends of the pressure rod body 11, the second connecting rod 12 is distributed in the front-to-back direction, and the second connecting rod 12 is fixedly connected to the first connecting rod 221; the adjusting bolt 222 is distributed in the front-to-back direction, the adjusting bolt 222 and the stepper motor 223 are fixedly connected to the shell 21, and the adjusting bolt 222 is threadedly connected to the first connecting rod 221; the stepper motor 223 is connected to the adjusting bolt 222; the switch structure and the stepper motor 223 are both connected to the control module signal.

[0049] The operation of the stepper motor 223 is controlled by the switch structure; during the operation of the stepper motor 223, the adjusting bolt 222 is driven to rotate; specifically, in the present application, the stepper motor 223 drives the synchronous wheel to rotate through the synchronous belt during the operation, and the synchronous wheel is connected to the adjusting bolt 222, so that the adjusting bolt 222 is driven to rotate while the synchronous wheel rotates; since the adjusting bolt 222 is fixedly connected to the housing 21, and the adjusting bolt 222 is connected to the first connecting rod 221 through a thread, during the rotation of the adjusting bolt 222, the first connecting rod 221 is driven to move forward and backward along the adjusting bolt 222; whether the movement of the first connecting rod 221 is forward or backward is determined by the rotation direction of the stepper motor 223, so the first connecting rod 221 can be controlled to move in the corresponding forward and backward directions by controlling the operation of the stepper motor 223.

[0050] When the first connecting rod 221 moves forward or backward, it drives the second connecting rod 12 connected thereto to move forward or backward, and then drives the pressure rod body 11 to move forward or backward through the second connecting rod 12; when the pressure rod body 11 moves forward, the distance between the pressure rod 1 and the bracket 3 increases; when the pressure rod body 11 moves backward, the distance between the pressure rod 1 and the bracket 3 decreases, thereby realizing the adjustment of the distance between the pressure rod 1 and the bracket 3.

[0051] To improve the automation level of the book pressing device, see Figure 3 , Figure 4As shown, the first connecting rod 221 in the present application includes a front connecting rod 2211 and a rear connecting rod 2212 arranged in parallel with each other, the front connecting rod 2211 is located on the side close to the bracket 3, and the rear connecting rod 2212 is located on the side away from the bracket 3; the front connecting rod 2211 and the rear connecting rod 2212 are connected by an axle pin, and the axle pin connection is provided with a gap; wherein the axle pin connection in the present application specifically refers to that, of the front connecting rod 2211 and the rear connecting rod 2212, one connecting rod is provided with a connecting shaft, and the other connecting rod is provided with a connecting hole adapted to the connecting shaft; the connecting shaft is located in the connecting hole, and there is a certain gap between the connecting shaft and the connecting hole, so that the connecting shaft can be connected to the rear connecting rod 2212 by the connecting shaft. The connecting shaft and the connecting hole connect the front connecting rod 2211 and the rear connecting rod 2212, and the connecting shaft can slide in the connecting hole within a certain range; the present application prefers that the gap is 2mm, that is, the distance between the front connecting rod 2211 and the rear connecting rod 2212 can float within a range of 2mm; the two ends of the rear connecting rod 2212 are connected to the pressure rod 1; the adjusting bolt 222 is connected to the front connecting rod 2211 by a thread; the front connecting rod 2211 is connected to a trigger plate 2213, and the rear connecting rod 2212 is provided with an infrared emitting device 2214 adapted to the trigger plate 2213, and the infrared emitting device 2214 is connected to the control module signal.

[0052] When it is necessary to turn the pages, the stepping motor 223 is controlled by the switch structure to drive the adjusting bolt 222 to rotate. When the adjusting bolt 222 rotates, it drives the front connecting rod 2211 to move forward, that is, drives the front connecting rod 2211 to move toward the direction close to the bracket 3; at the same time, since the front connecting rod 2211 is connected to the rear connecting rod 2212 by an axle pin, when the front connecting rod 2211 moves forward, it drives the rear connecting rod 2212 to move forward; and since the rear connecting rod 2212 is connected to the pressure rod 1, it drives the pressure rod 1 to move forward, so that the pressure rod 1 moves in the direction away from the bracket 3, and the distance between the pressure rod 1 and the bracket 3 increases, which is convenient for turning the pages of the book.

[0053] After turning the pages of the book, the stepper motor 223 is controlled to rotate in the opposite direction through the switch structure, so that the stepper motor 223 drives the adjusting bolt 222 to rotate in the opposite direction. When the adjusting bolt 222 rotates in the opposite direction, the front connecting rod 2211 is driven to move backward, that is, the front connecting rod 2211 is driven to move in the direction away from the bracket 3; at the same time, since the front connecting rod 2211 is connected to the rear connecting rod 2212 by an axle pin, when the front connecting rod 2211 moves backward, the rear connecting rod 2212 is driven to move backward; and since the rear connecting rod 2212 is connected to the pressure rod 1, the pressure rod 1 is driven to move backward, so that the pressure rod 1 moves in the direction close to the bracket 3; when the pressure rod 1 contacts the book, the book prevents the pressure rod 1 from continuing to move in the direction close to the bracket 3, and at the same time, The rear connecting rod 2212 connected to the pressure rod 1 stops moving backward; at this time, the stepper motor 223 continues to rotate, driving the front connecting rod 2211 to continue to move away from the bracket 3. At the same time, the front connecting rod 2211 drives the trigger plate 2213 to move away from the bracket 3; since the position of the rear connecting rod 2212 remains unchanged, the distance between the trigger plate 2213 and the infrared emitting device 2214 is reduced, and the trigger plate 2213 blocks the infrared rays emitted by the infrared emitting device 2214, triggering the stop operation command of the stepper motor 223, and the control module connected to the signal of the infrared emitting device 2214, such as a single-chip microcomputer, issues a stop operation command for the stepper motor 223, and the stepper motor 223 stops running, thereby achieving the clamping of the opened book pages.

[0054] The present invention is provided with an infrared emitting device 2214, which automatically triggers a stop command of the stepping motor 223 after the pressure rod 1 contacts the book, and controls the stepping motor 223 to stop running, so that the adjustment of the pressure rod 1 can automatically adapt to the thickness of the opened book page, has a high degree of automation, is easy to use, and has a wide range of applications.

[0055] Furthermore, in the present application, a buffer structure is provided between the front connecting rod 2211 and the rear connecting rod 2212, and it is further preferred that the buffer structure includes a spring.

[0056] By providing a buffer structure, when the rear connecting rod 2212 stops running and the front connecting rod 2211 continues to move away from the bracket 3, the buffer structure applies resistance to the front connecting rod 2211 in the direction of approaching the bracket 3, thereby preventing excessive force from being applied to the rear connecting rod 2212 during the movement of the front connecting rod 2211, which would cause excessive pressure on the book and improve safety.

[0057] In the present application, during the process of driving the pressure rod 1 to move forward and backward, the rotation direction of the output shaft of the stepper motor 223 is determined according to the extending direction of the thread of the adjusting bolt 222 and other conditions, and is not specifically limited herein.

[0058] The switch structure in the present application can be a switch button, or a corresponding command button can be set in the form of a touch screen; for ease of use, the present application preferably has a switch structure including an infrared switch, which is used to sense the user's gestures, and the control module converts the gestures sensed by the infrared switch into electrical signals, and controls the operation of the stepper motor 223 through the electrical signals. Specifically, the book pressing device provided in the present application includes a control module that is signal-connected to the infrared switch and the stepper motor 223, and the control module includes a single-chip microcomputer; the control module determines the instructions issued by the user according to the gestures sensed by the infrared switch, and then controls the operation of the stepper motor 223 according to the instructions; wherein a circuit board is provided in the housing 21, and the instructions are converted into electrical signals through the circuit board to control the operation of the stepper motor 223.

[0059] The present application preferably has two infrared switches, that is, the infrared switches include a first infrared switch and a second infrared switch, and the control module controls the operation of the stepper motor 223 according to the order in which the first infrared switch and the second infrared switch sense gestures.

[0060] For example, if during the operation of the book pressing device, the user's gesture passes through the first infrared switch first and then the second infrared switch, the control module determines that the instruction issued by the user at this time is a page turning instruction, and then controls the stepper motor 223 to operate, driving the pressure rod 1 to move in the direction away from the bracket 3 to release the clamping of the book pages; on the contrary, if the user's gesture passes through the second infrared switch first and then the first infrared switch, the control module determines that the instruction issued by the user at this time is a clamping instruction, and then controls the stepper motor 223 to operate, driving the pressure rod 1 to move in the direction close to the bracket 3 to clamp the book pages.

[0061] The first infrared switch and the second infrared switch can be set at any position that is convenient for operation. For ease of operation, the present application preferably locates the first infrared switch at a position near the bottom on the outside and the second infrared switch at a position near the top on the outside, so that when the user waves his hand upward on the outside of the shell 21, the page turning command is triggered, and the stepper motor 223 drives the pressure rod 1 to move away from the bracket 3. On the contrary, when the user waves his hand downward on the outside of the shell 21, the clamping command is triggered, and the stepper motor 223 drives the pressure rod 1 to move toward the bracket 3. The triggering method of the command is simple and easy to operate, and the triggering process conforms to the usage habits of most users.

[0062] In order to further expand the application scope of the book pressing device provided in the present application, the pressure rod adjustment structure 2 in the present application also includes a second adjustment structure 23, and the pressure rod adjustment structure 2 is slidably connected to the bracket 3 along the left and right direction through the second adjustment structure 23.

[0063] Since books come in a variety of sizes, by setting the pressure rod adjustment structure 2 to a structure that is slidably connected to the bracket 3 in the left and right directions, the pressure rod adjustment structure 2 can drive the pressure rod 1 to move in the left and right directions by sliding left and right, so that the pressure rod 1 can clamp books of different widths, thereby expanding the scope of use.

[0064] Specifically, the second adjustment structure 23 in the present application includes a first adjustment rod 231, a gear structure fixedly connected to the first adjustment rod 231, and a rack 232 meshing with the gear structure; the rack 232 is fixedly connected to the bracket 3 along the left-right direction.

[0065] The first adjusting rod 231 is distributed along the up and down directions; by rotating the first adjusting rod 231, the gear structure is driven to rotate; since the gear structure is meshed with the rack 232, and the rack 232 is fixedly connected to the bracket 3, when the gear structure rotates, it drives the pressure rod adjustment structure 2 to move along the left and right directions, and drives the pressure rod 1 to move along the left and right defense lines, thereby adjusting the position of the pressure rod 1 on the bracket 3 in the left and right directions, so that the pressure rod 1 can clamp books of different widths.

[0066] In order to improve the stability of the book pressing device structure, the present application preferably has two sets of gear structures, and the two sets of gear structures are respectively connected to the two ends of the first adjusting rod 231.

[0067] The number of gears in the gear structure can be one, two or more. The preferred gear structure of the present application includes a first gear 233 and a second gear 234 that are meshed with each other. The first gear 233 is fixedly connected to the first adjusting rod 231, and the second gear 234 is meshed with the first rack 232. Therefore, when the position of the pressure rod 1 in the left and right directions is adjusted, the moving direction of the pressure rod 1 is consistent with the rotation direction of the first adjusting rod 231, so that the adjustment of the pressure rod 1 is more in line with the sensory perception of most users, thereby improving the comfort of use.

[0068] To facilitate the rotation of the first adjustment rod 231, the second adjustment structure 23 in the present application also includes a first adjustment knob 235, which is fixedly connected to the first adjustment rod 231, so that the first adjustment rod 231 is driven to rotate by rotating the first adjustment knob 235; and it is further preferred that the first adjustment knob 235 is arranged below the first adjustment rod 231, so that the first adjustment knob 235 is located at the end close to the user for easy operation.

[0069] To ensure the stability of the book pressing device structure, the second adjustment structure 23 in the present application also includes a guide rail 236 and a second slide groove 237 adapted to the guide rail 236; the guide rail 236 and the second slide groove 237 are both distributed along the left and right directions; the guide rail 236 is fixedly connected to the bracket 3, and the second slide groove 237 is fixedly connected to the shell 21.

[0070] When the pressure rod adjustment structure 2 moves in the left-right direction, the guide rail 236 slides in the second slide groove 237 to improve the connection strength between the pressure rod adjustment structure 2 and the bracket 3, thereby improving the stability of the structure.

[0071] Furthermore, in the present application, a rubber or plastic structure is provided in the second slide groove 237 to increase the damping between the guide rail 236 and the second slide groove 237, so that when the rotation of the first adjustment knob 235 stops, the pressure rod adjustment structure 2 can stop moving immediately.

[0072] Another object of the present invention is to provide a reading bookshelf, see Figure 5 As shown, the reading bookshelf includes a bracket 3, a support 4 and two book pressing devices as described above; the two book pressing devices are respectively arranged on both sides of the bracket 3; and the support 4 is rotatably connected to the bracket 3.

[0073] The reading bookshelf provided by the present invention has book pressing devices arranged on both sides of a bracket 3, and the pressing rod 1 in the book pressing device is arranged as a structure that can be adjusted along the front and rear direction of the bracket 3, so that the distance between the pressing rod 1 and the bracket 3 can be adjusted, so that the reading bookshelf can clamp and fix books of any thickness, thereby expanding the use range of the reading bookshelf and improving the comfort of use.

[0074] Specifically, the bracket 3 in the present application includes a fixing portion 31, a first main body portion 32, a second main body portion 33, and an adjusting portion 34; wherein the first main body portion 32 and the second main body portion 33 are relatively arranged on the front side of the fixing portion 31; the first main body portion 32 and the second main body portion 33 are both slidably connected to the fixing portion 31 through the adjusting portion 34, so as to adjust the distance between the first main body portion 32 and the second main body portion 33 through the adjusting portion 34.

[0075] The fixing portion 31, the first main portion 32 and the second main portion 33 are all plate-like structures; the first main portion 32 and the second main portion 33 are both slidably connected to the fixing portion 31, the fixing portion 31 is located at the rear side, and the first main portion 32 and the second main portion 33 are both located at the front side. When a gap is left between the first main portion 32 and the second main portion 33, a groove recessed toward the rear side formed by the first main portion 32, the second main portion 33 and the fixing portion 31 is formed on the bracket 3, and the groove constitutes a space for accommodating the spine of a book; through the action of the adjusting portion 34, the first main portion 32 and the second main portion 33 can both slide along the fixing portion 31, and the distance between the first main portion 32 and the second main portion 33 can be adjusted by sliding, that is, the space for accommodating the spine of a book is adjusted.

[0076] When the reading bookshelf is used specifically, firstly, the distance between the first main body 32 and the second main body 33 is adjusted to be greater than the thickness of the book to be read through the adjustment part 34, and then the spine of the book is placed between the first main body 32 and the second main body 33, and the distance between the first main body 32 and the second main body 33 is reduced through the adjustment part 34, so that the first main body 32 and the second main body 33 are both in contact with the book, and the book is clamped, thereby achieving fixation of the book.

[0077] The reading bookshelf provided by the present invention, on the one hand, by arranging the first main body part 32 and the second main body part 33 to be slidably connected to the fixing part 31, a space for accommodating the spine of the book can be formed on the bracket 3, the spine of the book is placed in the space, and then the distance between the first main body part 32 and the second main body part 33 is adjusted by the adjustment part 34, so that the second main body part 32 and the second main body part 33 clamp the book to prevent the spine from bulging toward the side close to the reader, thereby preventing the opened pages from being closed, and improving the comfort of use; on the other hand, because the distance between the first main body part 32 and the second main body part 33 can be adjusted, the reading bookshelf provided by the present application can clamp books of different thicknesses and has a wide range of applications.

[0078] In addition, to facilitate the operation of the book pressing device, the present application preferably arranges the first infrared switch and the second infrared switch on the outside of the bracket 3, so that the user can operate the book pressing device by waving his hand up or down on the outside of the bracket 3.

[0079] The present application further preferably sets a plastic plate 35 on the outside of the bracket 3, and sets the first infrared switch and the second infrared switch inside the plastic plate 35. On the one hand, infrared light can pass through the plastic plate 35 for gesture sensing, and on the other hand, the plastic plate 35 can protect the first infrared switch and the second infrared switch and improve the aesthetics of the reading bookshelf.

[0080] To adjust the distance between the first main body 32 and the second main body 33, see Figure 6 As shown, the adjustment part 34 in the present application includes a second adjustment rod 341 and a third adjustment structure 342 fixedly connected to the second adjustment rod 341; the second adjustment rod 341 is rotationally connected to the fixed part 31; and the third adjustment structure 342 is slidingly connected to the first main body part 32 and the second main body part 33 at the same time.

[0081] In order to improve the stability and aesthetics of the bracket 3, the present application preferably configures the fixed portion 31 to be a hollow structure, and the second adjustment rod 341 is arranged through the fixed portion 31 and is rotatably connected to the fixed portion 31; at the same time, the third adjustment structure 342 is arranged in the fixed portion 31, and the third adjustment structure 342 is slidably connected to the first main body portion 32 and the second main body portion 33.

[0082] When it is necessary to adjust the distance between the first main body 32 and the second main body 33, rotate the second adjusting rod 341. When the second adjusting rod 341 rotates, it drives the third adjusting structure 342 to move. Then, the action of the third adjusting structure 342 drives the first main body 32 and the second main body 33 to slide accordingly along the fixed part 31, thereby realizing the adjustment of the distance between the first main body 32 and the second main body 33.

[0083] For details, see Figure 6 , Figure 7 As shown, the third adjustment structure 342 in the present application includes a first bevel gear 3421, a second bevel gear 3422, a third bevel gear 3423, a first threaded rod 3424, a second threaded rod 3425, a first slider 3426 and a second slider 3427, wherein the first bevel gear 3421 is fixedly connected to the second adjustment rod 341, the second bevel gear 3422 and the third bevel gear 3423 are arranged opposite to each other, and the second bevel gear 3422 and the third bevel gear 3423 are both meshed with the first bevel gear 3421. ; The second bevel gear 3422 is fixedly connected to the first threaded rod 3424, and the third bevel gear 3423 is fixedly connected to the second threaded rod 3425; the first slider 3426 is threadedly connected to the first threaded rod 3424, and the first slider 3426 is fixedly connected to the first main body 32; the second slider 3427 is threadedly connected to the second threaded rod 3425, and the second slider 3427 is fixedly connected to the second main body 33; the number of the first slider 3426 and the second slider 3427 in this application are both two.

[0084] When the distance between the first main body 32 and the second main body 33 needs to be adjusted, the second adjusting rod 341 is rotated. When the second adjusting rod 341 rotates, the first bevel gear 3421 is driven to rotate. Since the second bevel gear 3422 and the third bevel gear 3423 are both meshed with the first bevel gear 3421, and the second bevel gear 3422 and the third bevel gear 3423 are arranged opposite to each other, when the first bevel gear 3421 rotates, the second bevel gear 3422 and the third bevel gear 3423 are driven to rotate in opposite directions, and then the second bevel gear 3422 is further driven to rotate. The first threaded rod 3424 and the second threaded rod 3425 are driven to rotate by the third bevel gear 3423, and the rotation directions of the first threaded rod 3424 and the second threaded rod 3425 are opposite; since the first slider 3426 is connected to the first threaded rod 3424 by a thread, and the position of the first threaded rod 3424 does not change during the rotation process, the first slider 3426 is driven to move along the axial direction of the first threaded rod 3424 while the first threaded rod 3424 rotates; and since the first slider 3426 is fixedly connected to the first main body 32, the first slider 342 6, the first main body 32 is driven to move along the axial direction of the first threaded rod 3424; similarly, since the second slider 3427 is connected to the second threaded rod 3425 through a thread, and the position of the second threaded rod 3425 does not change during the rotation process, the second slider 3427 is driven to move along the axial direction of the second threaded rod 3425 when the second threaded rod 3425 rotates; and since the second slider 3427 is fixedly connected to the second main body 33, the second slider 3427 moves, and the second main body 33 is driven to move along the axial direction of the second threaded rod 3425 when the second main body 33 moves. and because the first threaded rod 3424 and the second threaded rod 3425 rotate in opposite directions, the first slider 3426 and the second slider 3427 move in opposite directions, so that the first main body 32 and the second main body 33 move in opposite directions, that is, the first main body 32 and the second main body 33 always move toward the center of the bracket 3 at the same time, or always move away from the center of the bracket 3 at the same time, thereby increasing or decreasing the distance between the first main body 32 and the second main body 33, and then realizing operations such as clamping or removing the spine of the book.

[0085] The maximum thickness of the book that the bracket 3 can clamp is determined by the length of the first threaded rod 3424 and the second threaded rod 3425. The maximum thickness of the book that can be clamped in the present application is preferably 24 mm; this thickness range can meet the clamping requirements of most books on the market.

[0086] The number of the third adjustment structures 342 can be one or more. To improve the structural stability of the bracket 3 , the present application preferably has two third adjustment structures 342 . The two third adjustment structures 342 are respectively disposed at both ends of the fixing portion 31 .

[0087] To facilitate the adjustment of the second adjustment rod 341 , the third adjustment structure 342 in the present application further includes a second adjustment knob 3428 , and the second adjustment knob 3428 is fixedly connected to the lower end of the second adjustment rod 341 .

[0088] By providing a second adjusting knob 3428 fixedly connected to the second adjusting rod 341 , the second adjusting rod 341 can be driven to rotate by rotating the second adjusting knob 3428 , thereby reducing the difficulty of operation and facilitating use.

[0089] Due to the long length of the second adjusting rod 341, a part of the structure extends out of the fixing part 31; in order to improve the stability and aesthetics of the structure, the present application preferably sets a shell 3411 on the exposed part of the second adjusting rod 341, and the shell 3411 is connected to the fixing part 31, and the second adjusting rod 341 is rotatably connected to the shell 3411; further, a baffle 3412 is set at the lower end of the shell 3411, and the baffle 3412 is fixedly connected to the shell 3411, and is vertically arranged with the first main body 32 and the second main body 33, and is located at the lower end of the first main body 32 and the second main body 33, so that when the first main body 32 and the second main body 33 clamp the book, the baffle 3412 is used to block the book to prevent the book from sliding down from the bracket 3.

[0090] Since the book spine is usually provided with a bonding part, which has a high hardness, it is difficult to clamp the bonding part of the book spine directly, and the book spine is easy to slip off; in order to improve the clamping force of the book, see Figure 5 , Figure 6 , Figure 8 As shown, in the present application, a first groove 321 of an L-shaped structure is provided on the inner side of the first main body portion 32, and a second groove 331 of an L-shaped structure is provided on the inner side of the second main body portion 33. The first groove 321 is matched with the second groove 331, and when the spine of a book is clamped, the first groove 321 and the second groove 331 together constitute a space for accommodating the bonding part; wherein the inner side of the first main body portion 32 and the inner side of the second main body portion 33 respectively refer to the parts of the first main body portion 32 and the second main body portion 33 that are in contact with the book to clamp the book.

[0091] Furthermore, in order to prevent the clamped book from slipping, a first clamping plate 3211 made of stainless steel is set on the top of the first groove 321, and a second clamping plate 3311 made of stainless steel is set on the top of the second groove 331. The first clamping plate 3211 and the second clamping plate 3311 are used to clamp the book to increase the friction between the book clamping device and the book, thereby improving the clamping stability.

[0092] Furthermore, in order to make the clamped book fit better with the bracket 3 and prevent the opened book from being closed, a first arc structure 322 is provided on the inner side of the first main body 32 in the present application, and the first arc structure 322 is located at the upper end of the first groove 321; a second arc structure 332 is provided on the inner side of the second main body 33, and the second arc structure 332 is provided at the upper end of the second groove 331; the first arc structure 322 is adapted to the second arc structure 332.

[0093] The first arc structure 322 is connected to the first clamping plate 3211, and the second arc structure 332 is connected to the second clamping plate 3311; by setting the first arc structure 322 and the second arc structure 332, after the spine of the book is placed in the space formed by the first groove 321 and the second groove 331, the two sides of the opened book can be well fitted with the first main body 32 and the second main body 33 respectively, so that the opened book can be laid flat on the book clamping device, thereby preventing the opened pages from being closed, which is convenient for use.

[0094] The bracket 4 is used to support the reading bookshelf so as to adjust the clamped books to a suitable height, a suitable angle, etc., so as to facilitate the user to read.

[0095] The bracket 4 can also be any structure that can be connected to the bracket 3; see Figure 5 As shown, the preferred bracket 4 of the present application includes a base 41, a vertical support portion 42 rotatably connected to the base 41, and a horizontal support portion 43 rotatably connected to the vertical support portion 42; the horizontal support portion 43 is rotatably connected to the bracket 3.

[0096] The base 41 may be a structure that is convenient for being placed on a desktop, or a structure that is convenient for being fixed to the desktop by clamping. The present application does not limit the specific structure of the base 41.

[0097] Specifically, the vertical support portion 42 in the present application includes a third connecting rod 421, a fourth connecting rod 422 sleeved on the outside of the third connecting rod 421, and a first oil cylinder 423; the bottom end of the fourth connecting rod 422 is rotatably connected to the base 41; the piston rod of the first oil cylinder 423 is fixedly connected to the fourth connecting rod 422, and the bottom end of the first oil cylinder 423 is rotatably connected to the base 41 and the third connecting rod 421; the horizontal support portion 43 includes a fifth connecting rod 431 and a sixth connecting rod 432 arranged in parallel with each other, and a connecting plate 433 rotatably connected to the fifth connecting rod 431; the fifth connecting rod 431 and the sixth connecting rod 432 are both rotatably connected to the bracket 3; the top end of the third connecting rod 421 and the top end of the fourth connecting rod 422 are both rotatably connected to the connecting plate 433; the bracket 4 also includes a second oil cylinder 44, the bottom end of the second oil cylinder 44 is rotatably connected to the fourth connecting rod 422, and the piston rod of the second oil cylinder 44 is rotatably connected to the fifth connecting rod 431.

[0098] Specifically, in the present application, a dovetail connection portion 311 is provided on the fixing portion 31 in the bracket 3, and the fifth connecting rod 431 and the sixth connecting rod 432 are both rotatably connected to the dovetail connection portion 11 via a pin shaft.

[0099] The vertical support portion 42 in the present application improves the aesthetics of the bracket 4 on the one hand by sleeved the fourth connecting rod 422 on the outside of the third connecting rod 421, and on the other hand, the connection points of the third connecting rod 421 and the connecting plate 433, the connection points of the third connecting rod 421 and the base 41, the connection points of the fourth connecting rod 422 and the connecting plate 433, and the connection points of the fourth connecting rod 422 and the base 41 together form a parallelogram structure, and the parallelogram structure is used to keep the angle of the bracket 4 stable, avoiding the angle of the bracket 4 from changing by itself during use without adjustment by the user, thereby improving the stability and safety of the bracket 4 structure.

[0100] The horizontal support portion 43 in the present application, through the fifth connecting rod 431, the sixth connecting rod 432, the connecting plate 433 and the dovetail connecting portion 311, together form a parallelogram structure. The parallelogram structure is used to keep the angle of the reading bookshelf stable, and the angle will not change during use due to the weight of the reading bookshelf itself.

[0101] The reading bookshelf provided by the present invention, through the two parallelogram structures in the bracket 4, on the one hand, enables the bracket 4 to adjust the height and angle of the reading bookshelf, and on the other hand, enables the bracket 4 to maintain the angle unchanged after the adjustment is completed, thereby improving the stability of the structure.

[0102] There are two first oil cylinders 423, and the two first oil cylinders 423 are respectively arranged on both sides of the fourth connecting rod 422; for the convenience of operation, the present application preferably has the damping direction of the second oil cylinder 44 upward. On the one hand, it is convenient to support the bracket 3 through the damping of the second oil cylinder 44, thereby improving the stability of the reading bookshelf structure; on the other hand, it reduces the difficulty of lifting the bracket 3 upward, thereby reducing the difficulty of adjusting the angle of the bracket 3.

[0103] Similarly, to facilitate the adjustment of the bracket 4, the present application preferably has the damping direction of the first cylinder 423 as downward, so that when the vertical support part 42 is adjusted forward or backward, it is necessary to overcome the damping force of the first cylinder 423, and the first cylinder 423 can be used to keep the vertical support part 42 balanced after being adjusted forward or backward, while also reducing the difficulty of adjusting the vertical support part 42 to the vertical direction, making operation easier.

[0104] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto.
