Description

Technical Field

[0001] This invention relates to the field of book weight technology, and more specifically, to a multifunctional book weight. Background Technology

[0002] In this era of knowledge explosion, people's demand for reading is increasing, and reading has become a widespread, nationwide interaction. However, with frequent use, the corners of books inevitably warp or wrinkle. In addition, in the fast-paced modern life, most people simply don't have the energy to maintain their books. Neglecting book protection over a long period not only significantly reduces the lifespan of books but also makes them look unsightly.

[0003] In existing technologies, there are specialized corner clips designed to avoid the aforementioned drawbacks. Corner clips protect the book corners and prevent them from folding after reading. Some corner clips are clip-like, directly holding the book corner in place, while others have a groove into which the corner can be inserted to secure it. However, regardless of the design, the corner clip's securing function interferes with turning the pages. To turn the page while reading, the clip must be removed. Furthermore, each corner clip can only hold a certain thickness of the book corner, while different books have different thicknesses. Therefore, different types of corner clips are needed to hold corners of varying thicknesses, limiting the applicability of a single type of corner clip.

[0004] Therefore, how to solve the problems of fixed book corner clips affecting book turning, the limited applicable book corner thickness of the same type of book corner clip, and the narrow range of application in the existing technology has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional book weight to solve the technical problems of existing book corner clips, such as the fixed effect on book turning, the limited applicability of a single type of book corner clip to a single book corner thickness, and a narrow range of applications. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] This invention provides a multifunctional book weight, comprising:

[0007] The pad includes a first edge and a second edge that are perpendicular to each other;

[0008] An upper clamping plate assembly is disposed above the pad plate. The upper clamping plate assembly includes a third edge and a fourth edge that are perpendicular to each other, wherein the first edge corresponds to the third edge and the second edge corresponds to the fourth edge.

[0009] The first telescopic plate assembly is capable of changing its length along the telescopic direction. Its lower end is fixedly connected to the first edge of the pad, and its upper end is rotatably connected to the third edge of the upper clamping plate assembly. The first telescopic plate assembly is perpendicular to the pad.

[0010] A first locking structure is used to lock the upper clamping plate assembly. When the upper clamping plate assembly is rotated to be perpendicular to the first telescopic plate assembly, the first locking structure locks the upper clamping plate assembly. The upper clamping plate assembly and the first telescopic plate assembly are relatively fixed. At this time, the upper clamping plate assembly and the pad form a receiving space for clamping the corner of the book.

[0011] The second telescopic plate assembly is capable of varying length along the telescopic direction, with its lower end connected to the second edge of the pad and its upper end detachably connected to the fourth edge of the upper clamping plate assembly.

[0012] A second locking structure is used to lock the first telescopic plate assembly and / or the second telescopic plate assembly to fix the distance between the pad and the upper clamping plate assembly.

[0013] Preferably, the upper clamping plate assembly includes an upper clamping plate, a lower clamping plate disposed below the upper clamping plate, and a tightening member. The third edge and the fourth edge are disposed on the upper clamping plate. The upper clamping plate is provided with a threaded hole. The outer surface of the tightening member is provided with an external thread for engaging the threaded hole. The lower end of the tightening member is rotatably connected to the lower clamping plate. A spring is also provided between the upper clamping plate and the lower clamping plate, and the spring is sleeved on the outer periphery of the tightening member.

[0014] Preferably, the first locking structure is configured as a snap-fit ​​structure, the snap-fit ​​structure including a first snap-fit ​​block and a first snap-fit ​​groove, the first snap-fit ​​block being disposed on one of the upper clamping plate and the first telescopic plate assembly, the first snap-fit ​​groove being disposed on the other, and the first snap-fit ​​block being able to extend into the first snap-fit ​​groove.

[0015] Preferably, both the first telescopic plate assembly and the second telescopic plate assembly include a plurality of interlocking straight plates. In any two adjacent straight plates, one of the straight plates is provided with a groove and a slot, and the other straight plate extends into the groove through the slot. A stop is provided at the slot to prevent the straight plate located in the groove from dislodging from the groove. A second locking structure is provided between any two adjacent straight plates.

[0016] Preferably, the second locking structure includes a spring pin and a plurality of positioning holes. In any two adjacent straight plates, the spring pin is disposed on one of the straight plates, and the positioning holes are disposed on the side wall of the other straight plate. The positioning holes are arranged at intervals along the extension and retraction direction of the second telescopic plate assembly, and the spring pin can extend into the positioning holes.

[0017] Preferably, the lower end of the second telescopic plate assembly is rotatably connected to the second edge of the pad, and the upper end is connected to the fourth edge of the upper clamping plate assembly via a snap-fit ​​structure.

[0018] Preferably, the buckle structure includes a second buckle block and a second buckle groove. The second buckle block is disposed on one of the second telescopic plate assembly and the upper clamping plate assembly, and the second buckle groove is disposed on the other. The second buckle block can extend into the second buckle groove.

[0019] Preferably, the second telescopic plate assembly has a strip-shaped plate on the side facing the receiving space. When the second telescopic plate assembly rotates relative to the pad to the first position, the strip-shaped plate is used to support the external device.

[0020] Preferably, a bookmark is movably provided on the side of the second telescopic plate assembly facing the receiving space, and the moving direction of the bookmark is consistent with the telescopic direction of the second telescopic plate assembly.

[0021] Preferably, the bottom of the pad is provided with a rubber strip.

[0022] The technical solution provided by this invention includes a multifunctional book weight comprising a pad, an upper clamping plate assembly, a first telescopic plate assembly, a first locking structure, a second telescopic plate assembly, and a second locking structure. The pad includes a first edge and a second edge that are perpendicular to each other. The upper clamping plate assembly is positioned above the pad and includes a third edge and a fourth edge that are perpendicular to each other. The first edge corresponds to the third edge, and the second edge corresponds to the fourth edge. The first telescopic plate assembly can change its length along its telescopic direction, i.e., its height changes vertically. The lower end of the first telescopic plate assembly is fixedly connected to the first edge of the pad, and its upper end is rotatably connected to the third edge of the upper clamping plate assembly. The first telescopic plate assembly is perpendicular to the pad. The first locking structure is used to lock the upper clamping plate assembly. When the upper clamping plate assembly rotates to be perpendicular to the first telescopic plate assembly, the first locking structure engages. The locking structure locks the upper clamping plate assembly, and the upper clamping plate assembly and the first telescopic plate assembly are relatively fixed. At this time, the upper clamping plate assembly and the pad form a receiving space for clamping the book corner, that is, the upper clamping plate assembly is located directly above the pad. The second telescopic plate assembly can also change its length along its telescopic direction. The lower end of the second telescopic plate assembly is connected to the second edge of the pad, and the upper end is detachably connected to the fourth edge of the upper clamping plate assembly. The second locking structure is used to lock the first telescopic plate assembly and / or the second telescopic plate assembly, thereby fixing the height value of the first telescopic plate assembly and / or the second telescopic plate assembly. At this time, the distance between the pad and the upper clamping plate is fixed, that is, the receiving space is constant.

[0023] In this way, when using this multi-functional bookweight, place the bookweight on the table, lock the upper clamp assembly using the first locking mechanism, and connect the upper end of the second telescopic plate assembly to the fourth edge of the upper clamp assembly. Then, raise both the first and second telescopic plate assemblies to a suitable height, place the book corner within the receiving space, and adjust the height of the first and second telescopic plate assemblies until the upper clamp assembly just covers the book corner. Finally, lock the height using the second locking mechanism. When you need to turn the page, simply unlock the upper clamp assembly using the first locking mechanism, rotate the upper clamp assembly relative to the first telescopic plate assembly by a certain angle, and you can turn the page. After turning the page, rotate the upper clamp assembly back to its original position and relock it using the first locking mechanism.

[0024] With this design, you can turn the page simply by opening and closing the upper clamp assembly while fixing the book corners, without having to remove the entire book clip. Furthermore, the telescopic plate assembly can change the size of the storage space to hold book corners of different thicknesses, making it suitable for a wide range of applications and no longer limited to a single thickness.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] The purpose of this specific embodiment is to provide a multifunctional book clip that solves the problems of existing book corner clips, such as the fixed effect on turning pages, the limited applicable book corner thickness, and the small range of applications.

[0041] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0042] Please see Figure 1-11 In this embodiment, as Figure 1As shown, the multifunctional book weight includes a pad 1, an upper clamping plate assembly, a first telescopic plate assembly 6, a first locking structure, a second telescopic plate assembly 7, and a second locking structure. The pad 1 includes a first edge and a second edge that are perpendicular to each other. The upper clamping plate assembly is positioned above the pad 1 and includes a third edge and a fourth edge that are perpendicular to each other. The first edge corresponds to the third edge, and the second edge corresponds to the fourth edge; that is, the third edge is directly above the first edge, and the fourth edge is directly above the second edge. Figure 6 As shown, the first telescopic plate assembly 6 can change its length along its telescopic direction, that is, change its height in the vertical direction. The lower end of the first telescopic plate assembly 6 is fixedly connected to the first edge of the pad 1, and the upper end is rotatably connected to the third edge of the upper clamping plate assembly. The first telescopic plate assembly 6 is perpendicular to the pad 1, that is, the first telescopic plate assembly 6 is vertically arranged. Optionally, as shown... Figure 4 As shown, the upper edge of the first telescopic plate assembly 6 is rotatably connected to the third edge of the upper clamping plate assembly via a pivot. A first locking structure is used to lock the upper clamping plate assembly. When the upper clamping plate assembly rotates to be perpendicular to the first telescopic plate assembly 6 and directly above the pad 1, the first locking structure locks the upper clamping plate assembly, fixing its position. The upper clamping plate assembly and the first telescopic plate assembly 6 are relatively fixed, forming a receiving space between the upper clamping plate assembly and the pad 1. This receiving space is used to clamp the book corner, allowing the book corner to extend into and be clamped within this space. Figure 5 As shown, the lower end of the second telescopic plate assembly 7 is connected to the second edge of the pad 1, and the upper end is detachably connected to the fourth edge of the upper clamping plate assembly. Specifically, as shown... Figure 6 As shown, the second telescopic plate assembly 7 can also change its length along its telescopic direction. The lower end of the second telescopic plate assembly 7 can be fixedly connected to the second edge of the pad 1, and the two can also be rotatably connected by a pivot or hinge. The second locking structure is used to lock the first telescopic plate assembly 6 and / or the second telescopic plate assembly 7, thereby fixing the height value of the first telescopic plate assembly 6 and / or the second telescopic plate assembly 7. At this time, the distance between the pad 1 and the upper clamping plate 2 is fixed, that is, the accommodating space is constant. Specifically, the second locking structure is provided on the first telescopic plate assembly 6 or the second telescopic plate assembly 7, or the second locking structure can be provided on both the first telescopic plate assembly 6 and the second telescopic plate assembly 7.

[0043] In this way, when using this multi-functional bookweight, place the bookweight on the table, lock the upper clamp assembly using the first locking mechanism, and connect the upper end of the second telescopic plate assembly 7 to the fourth edge of the upper clamp assembly. Then, raise the first telescopic plate assembly 6 and the second telescopic plate assembly 7 together to a suitable height, place the book corner in the receiving space, and then adjust the height of the first telescopic plate assembly 6 and the second telescopic plate assembly 7 until the upper clamp assembly just presses down on the book corner. Finally, lock the height using the second locking mechanism. When you need to turn the page, simply unlock the upper clamp assembly using the first locking mechanism, rotate the upper clamp assembly relative to the first telescopic plate assembly 6 by a certain angle, and you can turn the page. After turning the page, rotate the upper clamp assembly back to its original position and relock it using the first locking mechanism.

[0044] With this design, you can turn the page simply by opening and closing the upper clamp assembly while fixing the book corners, without having to remove the entire book clip. Furthermore, the telescopic plate assembly can change the size of the storage space to hold book corners of different thicknesses, making it suitable for a wide range of applications and no longer limited to a single thickness.

[0045] In this embodiment, as Figure 10 As shown, the multi-functional book weight is used as a retractable bookshelf. When the multi-functional book weight is laid down, the upper clamp assembly and the pad 1 are set vertically, the first retractable plate assembly 6 or the second retractable plate assembly 7 is located at the bottom, and another retractable plate assembly is located on the side. Multiple books can be directly arranged and placed in the storage space.

[0046] In other embodiments, the lower end of the first telescopic plate assembly 6 is rotatably connected to the first edge of the pad 1, and the upper end is fixedly connected to the third edge of the upper clamping plate assembly. Thus, the first telescopic plate assembly 6 and the upper clamping plate assembly rotate together relative to the pad 1. Similarly, when the upper clamping plate assembly is directly above the pad 1, the first locking structure locks the upper clamping plate assembly and the first telescopic plate assembly 6, fixing their positions and creating a space for holding the book corner. In this way, when holding the book corner and needing to turn the page, the first locking structure unlocks the upper clamping plate assembly and the first telescopic plate assembly 6, causing them to rotate a certain angle relative to the pad 1, allowing the upper clamping plate assembly to detach from directly above the pad 1 and enabling page turning.

[0047] As an optional implementation, such as Figure 2As shown, the upper clamping plate assembly includes an upper clamping plate 2, a lower clamping plate 3, and a tightening member 4. The lower clamping plate 3 is located below the upper clamping plate 2, with its third and fourth edges positioned on the upper clamping plate 2. The upper clamping plate 2 has a threaded hole 201, and the outer surface of the tightening member 4 has an external thread for engaging the threaded hole 201. The tightening member 4 protrudes from the upper surface of the upper clamping plate 2, and its lower end is rotatably connected to the lower clamping plate 3. The space between the pad 1 and the lower clamping plate 3 serves as an accommodating space. Thus, when an external force is applied to the tightening member 4, it rotates relative to the upper clamping plate 2, causing the tightening member 4 to move up and down relative to the upper clamping plate 2, thereby causing the tightening member 4 to move the lower clamping plate 3 up and down. In this embodiment, the tightening member 4 is a bolt, with the bolt's nut located on the upper end face of the upper clamping plate 2. An external force is applied to the nut to tighten the bolt. Specifically, the lower end of the tightening member 4 is provided with an annular groove, which surrounds the outer periphery of the tightening member 4. The upper end face of the lower clamping plate 3 is connected to a circular tube section. The lower end of the tightening member 4 extends into the circular tube section, and the side wall of the circular tube section is provided with a fastening hole. A fastener, such as a screw 21, passes through the fastening hole and extends into the annular groove. In this way, the tightening member 4 will not drive the lower clamping plate 3 to rotate while rotating, but will only drive the lower clamping plate 3 to rise and fall.

[0048] After using the telescopic plate assembly to clamp the book corners with the upper clamping plate assembly and the pad 1 for book weighting, there will still be some gaps between the pages, which will not effectively flatten the book corners and will result in the pages not fitting together completely. With this new design, after the upper clamping plate assembly fixes the book corners, the position of the lower clamping plate 3 can be adjusted by the tightening component 4, thereby pressing the lower clamping plate 3 firmly against the book corners, effectively fixing them, avoiding gaps, and making the book corners flatter.

[0049] In a preferred embodiment, such as Figure 2 As shown, an elastic element is also provided between the upper clamping plate 2 and the lower clamping plate 3. Optionally, the elastic element is a spring 5, which is sleeved on the outer periphery of the tightening member 4.

[0050] With this configuration, the upper end of the spring 5 acts on the upper clamping plate 2 and the lower end acts on the lower clamping plate 3, which plays a certain role in buffering and preventing excessive pressure on the book corner at the connection point between the lower clamping plate 3 and the tightening part 4.

[0051] Preferably, the first locking structure is configured as a snap-fit ​​structure, such as... Figure 1 and Figure 4As shown, the snap-fit ​​structure includes a first snap-fit ​​block 12 and a first snap-fit ​​groove 13. The first snap-fit ​​block 12 is disposed on one of the upper clamping plate 2 and the first telescopic plate assembly 6, and the first snap-fit ​​groove 13 is disposed on the other. When the upper clamping plate 2 rotates to be perpendicular to the first telescopic plate and is located directly above the pad 1, the first snap-fit ​​block 12 can extend into the first snap-fit ​​groove 13, that is, the first snap-fit ​​block 12 is snapped into the first snap-fit ​​groove 13. At this time, the position of the upper clamping plate 2 is fixed, and it cannot continue to rotate or return to its original position. When an external force is applied to the upper clamping plate 2, the first snap-fit ​​block 12 can disengage from the first snap-fit ​​groove 13, and the upper clamping plate 2 can then resume rotation. In this embodiment, the first snap-fit ​​block 12 is disposed on the upper clamping plate 2, and the first snap-fit ​​groove 13 is disposed at the upper end of the first telescopic plate assembly 6. Specifically, the first snap-fit ​​block 12 has slight elastic deformation properties, and can be squeezed into the first snap-fit ​​groove 13, and can also be squeezed out of the first snap-fit ​​groove 13.

[0052] As an optional implementation, such as Figure 3 As shown, both the first telescopic plate assembly 6 and the second telescopic plate assembly 7 include multiple interlocking straight plates 8. A second locking structure is provided between any two adjacent straight plates 8. In any two adjacent straight plates 8, one straight plate 8 has a groove 9 and a slot 10, and the other straight plate 8 extends into the groove 9 through the slot 10. Specifically, the groove 9 is located on the lower straight plate 8, and the slot 10 is located on the upper edge of the straight plate 8. The upper straight plate 8 can extend into and move relative to the lower straight plate 8. Of course, in other embodiments, in any two adjacent straight plates 8, the groove 9 and the slot 10 can be located on the upper straight plate 8. Furthermore, as... Figure 3 As shown, a stop 11 is provided at the slot 10, and a protrusion is provided on the straight plate 8 located in the groove 9. When two adjacent straight plates 8 move to their maximum length, the stop 11 contacts the protrusion, thereby preventing the straight plate 8 located in the groove 9 from detaching from the groove 9 and avoiding the two adjacent straight plates 8 from detaching.

[0053] Specifically, each of the second locking structures includes a spring pin 14 and multiple positioning holes 15, such as Figure 3As shown, in any two adjacent straight plates 8, a spring pin 14 is disposed on one of the straight plates 8, and a positioning hole 15 is disposed on the side wall of the other straight plate 8. The positioning holes 15 are arranged at intervals along the extension and retraction direction of the second telescopic plate assembly 7, i.e., the vertical direction. The spring pin 14 can extend into different positioning holes 15. In this embodiment, the spring pin 14 is disposed on the side wall of the straight plate 8 located in the groove 9, and the positioning hole 15 is disposed on the side wall of the outer straight plate 8. When the second locking structure is in the unlocked state, the spring pin 14 is under force and extends into the interior of its straight plate 8, allowing relative movement between adjacent straight plates 8. When the second locking structure is in the locked state, the spring pin 14 corresponds to the position of a certain positioning hole 15. At this time, the spring pin 14 is not under force and pops out from the inner straight plate 8, no longer under the pressure. The spring pin 14 extends out from the inner straight plate 8 and out through the corresponding positioning hole 15 to the outside. At this time, the positions of the two adjacent straight plates 8 are fixed and cannot continue to slide relative to each other.

[0054] In a preferred embodiment, the lower end of the second telescopic plate assembly 7 is rotatably connected to the second edge of the pad 1, and the upper end is connected to the fourth edge of the upper clamping plate assembly via a snap-fit ​​structure. Specifically, the straight plate 8 of the second telescopic plate assembly 7 closest to the pad 1 is rotatably connected to the edge of the pad 1 via a pivot shaft; as shown... Figure 1 As shown, the snap-fit ​​structure includes a second snap-fit ​​block 16 and a second snap-fit ​​groove 17. The second snap-fit ​​block 16 is disposed on one of the second telescopic plate assembly 7 and the upper clamping plate assembly, and the second snap-fit ​​groove 17 is disposed on the other. The second snap-fit ​​block 16 can extend into the second snap-fit ​​groove 17.

[0055] In this embodiment, the second locking block 16 is disposed on the edge of the straight plate 8 of the second telescopic plate assembly 7 away from the pad plate 1, and the second locking groove 17 is disposed on the edge of the upper clamping plate 2. Specifically, the second locking block 16 has slight elastic deformation properties, and can be squeezed into the second locking groove 17, and can also be squeezed out of the second locking groove 17.

[0056] With this configuration, when the second telescopic plate assembly 7 is connected to the upper clamping plate 2 via the snap-fit ​​structure, the second telescopic plate assembly 7 and the first telescopic plate assembly 6 are perpendicular. At this time, the multi-functional book weight can be used to hold books and clamp the corners of books. When the snap-fit ​​relationship is released and the second telescopic plate assembly 7 is detached from the upper clamping plate 2, the second telescopic plate assembly 7 can be laid flat so that it is on the same horizontal plane as the pad 1. At this time, the upper clamping plate assembly and the pad 1 can not only clamp the corners of books, but also be used as a drawing clip, folder, etc.

[0057] As an optional implementation, such as Figure 7 As shown, a bookmark 19 is provided on the side of the second telescopic plate assembly 7 facing the receiving space. In this way, the position of the reading page can be marked on the corner of the book being held by the bookmark 19.

[0058] Preferably, a bookmark 19 is movably provided on the side of the second telescopic plate assembly 7 facing the receiving space, and the moving direction of the bookmark 19 is consistent with the telescopic direction of the second telescopic plate assembly 7. Specifically, each of two adjacent straight plates 8 of the second telescopic plate assembly 7 is provided with a strip hole 20. The length direction of the strip hole 20 is the same as the telescopic direction of the second telescopic plate assembly 7, and each strip hole 20 corresponds to the other. When the two adjacent straight plates 8 move relative to each other, the two strip holes 20 overlap and separate accordingly. When the length of the two adjacent straight plates 8 is the shortest, the overlap of the strip holes 20 is the greatest, and the overall length of the strip holes 20 is the smallest; when the length of the two adjacent straight plates 8 is the longest, the overlap of the strip holes 20 is the smallest, and the overall length of the strip holes 20 is the largest. Bookmark 19 is connected to a fastener, which can be a screw 21. The screw 21 passes through the strip hole 20. Nut 22 is located on the outside of the straight plate 8, and bookmark 19 is located on the inside of the straight plate 8. The screw 21 and nut 22 are threaded together, and the screw 21 is connected to the bookmark 19. When the nut 22 is loosened, the screw 21 can drive the bookmark 19 to move along the length of the strip hole 20. When the nut 22 is tightened, the screw 21 and the bookmark 19 are fixed.

[0059] Optionally, each straight plate 8 is provided with a separate strip hole 20. The length of the strip hole 20 is basically the same as the length of each straight plate 8 along the extension direction. In this way, the screw 21 can pass through different strip holes 20 and move to different positions within the strip holes 20 to mark any page position at the corner of the book.

[0060] With this design, the movable structure of bookmark 19 can mark different page positions at the corner of the book. When reading to any position, the corner of the page can be marked and fixed.

[0061] As an optional implementation, the second telescopic plate assembly 7 has a strip-shaped locking plate 18 on the side facing the receiving space. When the second telescopic plate assembly 7 rotates relative to the pad 1 to a first position, the strip-shaped locking plate 18 is used to support the external device. It should be noted that the "first position" here is the position where the second telescopic plate assembly 7 rotates relative to the pad 1 to be on the same horizontal plane as the pad 1. Specifically, the external device can be a book, or an electronic product such as a mobile phone or tablet. In this case, both the first telescopic plate assembly 6 and the second telescopic plate assembly 7 are provided with a second locking structure, so that the multi-functional book weight can be used as a support.

[0062] With this configuration, the lower end of an open book, electronic device, or other external device can rest against the strip tray 18, such as... Figure 9 As shown, the upper end of the external device can directly abut against the upper clamping plate assembly, thus serving as a support.

[0063] In a preferred embodiment, the strip card 18 is movably disposed on the second telescopic plate assembly 7 along the telescopic direction. Specifically, the movability of the strip card 18 is implemented in the same way as the movability of the bookmark 19 described above. The strip card 18 and the bookmark 19 can share the strip hole 20, which will not be described in detail here.

[0064] With this configuration, the tilt angle of the external device against the multi-functional paperweight can be adjusted by adjusting the position of the strip plate 18.

[0065] As an optional implementation, such as Figure 2 As shown, a rubber strip 23 is provided at the bottom of the pad 1, and the rubber strip 23 is attached to the bottom of the pad 1.

[0066] This setup increases the friction between the pad 1 and the external desktop.

[0067] The uses of this multifunctional bookweight will be specifically described in conjunction with the above embodiments. In this embodiment, the multifunctional bookweight has the following four functions:

[0068] Function 1: Used as a book cover, such as Figure 8 As shown. Specifically, place the multi-functional book weight vertically on the table with the pad 1 below. First, rotate the upper clamping plate assembly so that the first locking block 12 engages in the first locking slot 13. Similarly, rotate and extend the second telescopic plate assembly 7 so that the second locking block 16 also engages in the second locking slot 17. Then, place the corner of the target book between the pad 1 and the lower clamping plate 3, i.e., in the receiving space. Adjust the extension length of the first telescopic plate assembly 6 and the second telescopic plate assembly 7 until the lower clamping plate 3 just presses down on the corner of the book. At this time, the spring pin 14 extends into the corresponding positioning hole 15, and the extension length is locked and fixed. Further tighten the tightening piece 4 to fine-tune the lower clamping plate 3 so that the lower clamping plate 3 completely presses down on the corner of the book.

[0069] When it is necessary to turn the page, loosen the locking structure so that the first locking block 12 disengages from the first locking slot 13, and the upper clamping plate assembly rotates upward to pull out the page. After the page is turned, rotate the upper clamping plate assembly back and re-lock the first locking block 12 and the first locking slot 13.

[0070] In a preferred embodiment, when using the bookmark 19, it is also necessary to first loosen the snap-fit ​​structure so that the first snap-fit ​​block 12 is disengaged from the first slot 13, the upper clamping plate assembly is rotated upward, the book is turned to the desired position, the fastener, i.e., the screw 21, is loosened, the bookmark 19 is moved up and down to the appropriate position, and then the fastener is tightened to fix the bookmark 19. The book is closed and the upper clamping plate assembly is rotated to close the upper clamping plate assembly, so that the first snap-fit ​​block 12 and the first slot 13 are snapped back together.

[0071] Function two: Used as a support, such as Figure 9As shown. Specifically, place the multi-functional book weight on the external support plane, i.e., the table, with the pad 1 below. Rotate the second telescopic plate assembly 7 so that it is on the same horizontal plane as the pad 1. Unfold the second telescopic plate assembly 7 and lock it. Then, freely adjust the first telescopic plate assembly 6 to a suitable height and lock it. The upper clamping plate assembly is also rotated to the position where the first locking block 12 and the first locking slot 13 are engaged. Align the bottom of the target object, such as a book, mobile phone, or tablet, with the strip plate 18, and place the top of the target object against the upper clamping plate 2.

[0072] Function three: Used as a telescopic bookshelf, such as Figure 10 As shown, specifically, the multi-functional book weight is placed horizontally, with the upper clip 2 and the pad 1 set vertically. The first telescopic plate assembly 6 is located at the bottom, and the second telescopic plate assembly 7 is located on the side, so that the first locking block 12 engages with the first locking slot 13, and the second locking block 16 engages with the second locking slot 17. Then, the bookshelf can be freely extended and retracted as needed. After reaching the appropriate length, the two telescopic plate assemblies are locked and fixed. Further tightening of the tightening piece 4 can be used to fine-tune the position of the lower clip 3 and adjust the book spacing.

[0073] Function four: It can be used as a drawing folder, exam paper folder, or document folder, such as... Figure 11 As shown. Specifically, place the multi-functional book weight vertically on the table with the pad 1 below. Rotate the upper clamp assembly and engage the first locking block 12 with the first locking slot 13. Then rotate the second telescopic plate assembly 7 so that it is on the same horizontal plane as the pad 1. Unfold the second telescopic plate assembly 7 and place the drawing board, test paper, documents, etc. on the pad 1. Align the side edge of the target object with the inner side of the first telescopic plate assembly 6. Adjust the height of the first telescopic plate assembly 6 until it just presses down on the target object. At this time, the first telescopic plate assembly 6 is locked and its height is fixed. Finally, while pressing down the lower pressure plate, rotate the tightening member 4 to make fine adjustments to the lower clamp 3 until the lower clamp 3 completely presses down on the target object.
