Description

Technical Field

[0001] This utility model relates to the field of teaching tools technology, specifically to a textbook holder. Background Technology

[0002] Traditional teaching materials are usually books, and with the development of technology, textbooks will still be used in conjunction with teaching materials and are an indispensable part of classroom teaching. Therefore, it is necessary to pay attention to the ease of use of textbooks by teachers.

[0003] Currently, when using textbooks, most teachers need to repeatedly press the glue seal after turning to a page to deform it and maintain the page's shape for easy viewing. However, in practice, especially with thicker books, the glue seal is difficult to deform, causing the pages to flip back automatically after being turned, requiring teachers to turn the page again each time, which is extremely inconvenient. While some teachers use folders to assist teaching, clipping the sides of the open textbook to prevent it from closing automatically, this is often ineffective. Since folders usually only have clips at the top, when the bottom of the open textbook is clipped, the angle is significantly smaller than the top, resulting in a tilted view and hindering reading. Especially for some longer textbooks, the distance between the clip and the bottom of the textbook is relatively far, which weakens the clip's effect on the bottom of the textbook, resulting in a poor display effect. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide a textbook storage clip with an upper and lower clamp. These clamps secure the top and bottom of the textbook, respectively, preventing the opened pages from automatically flipping back and maintaining stability after page turning. This also prevents the opened pages from tilting, facilitating teacher viewing. Furthermore, a telescopic frame is provided between the upper and lower clamps, allowing adjustment of the distance between them. This accommodates textbooks of different lengths and facilitates product storage, resulting in a more rational structural design.

[0005] The specific technical solution is as follows: A textbook storage clip has the following features, including: The clamping plate includes an upper clamping plate and a lower clamping plate, which are arranged in parallel. Both the upper and lower clamping plates are equipped with pressure plates, and the pressure plates on the upper and lower clamping plates are arranged in opposite directions. The telescopic frame is positioned between the upper and lower clamping plates, with both ends connected to the upper and lower clamping plates respectively. Furthermore, the telescopic direction of the telescopic frame is perpendicular to the arrangement direction of the upper and lower clamping plates.

[0006] The aforementioned textbook placement clip has a telescopic frame that is a multi-link scissor lift structure.

[0007] In the aforementioned textbook placement clip, both the upper and lower clamps have sliding grooves along their length, and each sliding groove contains a slider. Both the upper and lower clamps have hinge holes at the same end, while the sliding grooves on the upper and lower clamps are located at the other end. The two connecting rods at the end of the telescopic frame are respectively hinged to the hinge holes and the sliders.

[0008] In the aforementioned textbook placement clip, the slide includes an outer slide and an inner slide, which are connected. The width of the outer slide is greater than that of the inner slide. The slider is a T-shaped slider, with its large end and small end slidably disposed in the outer slide and inner slide, respectively. The connecting rod of the telescopic frame is hinged to the small end of the slider by a screw.

[0009] The aforementioned textbook storage clip has pressure plates at both ends of both the upper and lower clips.

[0010] In the aforementioned textbook storage clip, the pressure plate is a spring clip.

[0011] In the aforementioned textbook placement clip, floating components are provided between the upper clamping plate and the corresponding pressure plate, and between the lower clamping plate and the corresponding pressure plate. The floating components include a rotating shaft and a locking screw. Mounting holes are provided on both the upper and lower clamping plates. One end of the rotating shaft is installed in the mounting hole, and the other end of the rotating shaft is connected to the pressure plate. The locking screw is installed on the end of the rotating shaft connected to the pressure plate and presses the pressure plate.

[0012] In the aforementioned textbook placement clip, the floating component further includes a floating spring. The end of the mounting hole near the shaft is a constricted structure, and the end of the shaft located inside the mounting hole is provided with a protruding retaining edge. The floating spring is disposed inside the mounting hole and sleeved on the shaft, and the two ends of the floating spring abut against the constricted structure of the mounting hole and the retaining edge, respectively.

[0013] In the aforementioned textbook placement clip, the floating component further includes a support sleeve, which is fitted onto one end of the rotating shaft extending outside the mounting hole, and one end of the support sleeve abuts against the pressure plate.

[0014] The positive effects of the above technical solution are: The aforementioned textbook holder, with its upper and lower clamps equipped with pressure plates and a telescopic frame between them, allows the textbook to be placed between the upper and lower clamps. The pressure plates on the upper and lower clamps respectively hold the top and bottom of the textbook in place, preventing it from closing automatically and facilitating teacher viewing. Furthermore, the simultaneous pressure on both the top and bottom of the textbook prevents uneven pressure on the paper and avoids tilting, further facilitating teaching. Additionally, the distance between the upper and lower clamps can be adjusted by extending and retracting the telescopic frame to accommodate textbooks of different lengths, making the structure more flexible, adaptable, and easy to store and carry.

Detailed Implementation

[0017] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0018] Figure 1 This is a structural diagram of an embodiment of a textbook placement clip according to this utility model. Figure 1 and Figure 2 As shown, the textbook placement clip provided in this embodiment includes: a clip plate 1 and a telescopic frame 3.

[0019] Specifically, the clamp 1 includes an upper clamp 11 and a lower clamp 12, which are arranged in parallel, ensuring that their orientations are consistent. When the upper clamp 11 adapts to the top contour of the textbook, the lower clamp 12 simultaneously adapts to the bottom contour, providing conditions for subsequently clamping the top and bottom of the textbook. Furthermore, pressure plates 2 are provided on both the upper clamp 11 and the lower clamp 12, and these pressure plates 2 are arranged facing opposite directions. This ensures that when the textbook is placed between the upper clamp 11 and the lower clamp 12, the pressure plates 2 on both extend into the paper area of ​​the textbook, thus pressing down the top and bottom of the textbook and preventing the opened textbook from automatically closing and affecting teaching. Specifically, the telescopic frame 3 is positioned between the upper clamping plate 11 and the lower clamping plate 12, with both ends connected to the upper clamping plate 11 and the lower clamping plate 12 respectively. The telescopic frame 3 connects the upper clamping plate 11 and the lower clamping plate 12 to form an integrated structure, facilitating carrying and use. Simultaneously, the telescopic movement of the telescopic frame 3 allows for adjustment of the distance between the upper clamping plate 11 and the lower clamping plate 12, enabling variations in the distance to accommodate clamping requirements of textbooks of different lengths. This results in a more flexible and adaptable structure. Furthermore, the telescopic direction of the telescopic frame 3 is perpendicular to the arrangement direction of the upper clamping plate 11 and the lower clamping plate 12. When the upper clamping plate 11 and the lower clamping plate 12 are arranged parallel to the top and bottom contours of the textbook, the telescopic direction of the telescopic frame 3 corresponds to the length direction of the textbook, ensuring that the deformation of the telescopic frame 3 directly corresponds to the length direction of the textbook, maximizing the utilization of the telescopic frame 3.

[0020] More specifically, the telescopic frame 3 is preferably a multi-link 31 scissor lift structure. By increasing the number of links 31, the length of each link 31 can be effectively reduced while maintaining the telescopic range, thereby reducing the width of the telescopic frame 3 and facilitating product miniaturization. It is worth noting that since the multi-link 31 scissor lift structure is a commonly used telescopic structure on the market and has mature applications in products such as folding doors and elevators, the specific structure and working principle of the telescopic frame 3 with the multi-link 31 scissor lift structure will not be described in detail in this embodiment.

[0021] Figure 2 This is a sectional view showing the installation of the slide groove and slider in a textbook placement clip according to this utility model. Figure 1 and Figure 2As shown, both the upper clamping plate 11 and the lower clamping plate 12 have sliding grooves 111 along their length, and sliders 112 are installed in each of the sliding grooves 111. The position of the sliders 112 is changed by moving them in the sliding grooves 111, which provides conditions for adapting to the position changes of the ends of the connecting rods 31 when the telescopic frame 3 is extended or retracted. At the same time, both the upper clamping plate 11 and the lower clamping plate 12 have hinge holes at the same end. In this case, the sliding grooves 111 on the upper clamping plate 11 and the lower clamping plate 12 are located at the other end. The two connecting rods 31 at the ends of the telescopic frame 3 are respectively hinged to the hinge holes and the sliders 112. Since the hinge holes on the upper clamping plate 11 and the lower clamping plate 12 are located at the same end, and the sliding grooves 111 are located at the other end, the positions of the upper clamping plate 11 and the lower clamping plate 12 relative to the telescopic frame 3 can always remain consistent when the telescopic frame 3 is extended or retracted. This ensures that when the upper clamping plate 11 presses down on the top middle of the textbook, the lower clamping plate 12 can simultaneously press down on the bottom middle of the textbook, resulting in a better pressing effect.

[0022] More specifically, the sliding grooves 111 on the upper clamping plate 11 and the lower clamping plate 12 both include an outer sliding groove 1111 and an inner sliding groove 1112. At this time, the outer sliding groove 1111 and the inner sliding groove 1112 are connected, and the groove width of the outer sliding groove 1111 is greater than the groove width of the inner sliding groove 1112, so that the cross-section of the sliding groove 111 is stepped, which provides conditions for subsequently restricting the slider 112 to prevent the slider 112 from coming out of the sliding groove 111. Meanwhile, the slider 112 is a T-shaped slider 112, with the large end and small end of the slider 112 slidably disposed in the outer groove 1111 and the inner groove 1112, respectively. Furthermore, the connecting rod 31 of the telescopic frame 3 is hinged to the small end of the slider 112 by a screw 113. The large end of the slider 112 and the connecting rod 31 restrict the slider 112 within the groove 111, preventing the slider 112 from coming out of the groove 111 and maintaining the structural reliability of the telescopic frame 3 after the two ends are connected to the upper clamping plate 11 and the lower clamping plate 12.

[0023] More specifically, pressure plates 2 are provided at both ends of the upper clamping plate 11 and the lower clamping plate 12, so that the pressure plates 2 on both sides can press down the two sides of the released teaching materials respectively, preventing the teaching materials from turning the pages automatically and affecting the teaching. The structural design is more reasonable.

[0024] More specifically, the pressure plates 2 set on the upper clamping plate 11 and the lower clamping plate 12 are all spring sheets. The material of the pressure plates 2 is preferably metal, so that the pressure plates 2 can press the teaching materials under their own elastic force. In addition, the deformation of the pressure plates 2 can adapt to the pressing requirements of teaching materials of different thicknesses, and the structural design is more reasonable.

[0025] Figure 3 This is a cross-sectional view of a floating component of a textbook placement clip according to this utility model. Figure 1 and Figure 3As shown, floating components 4 are provided between the upper clamping plate 11 and the corresponding pressure plate 2, and between the lower clamping plate 12 and the corresponding pressure plate 2. Each floating component 4 includes a rotating shaft 41 and a locking screw 42. Mounting holes are provided on both the upper clamping plate 11 and the lower clamping plate 12, and one end of the rotating shaft 41 is installed in one of these holes, thus enabling its installation on the upper and lower clamping plates 11 and 12. Simultaneously, the other end of the rotating shaft 41 is connected to the pressure plate 2, and the locking screw 42 is installed on the end of the rotating shaft 41 connected to the pressure plate 2, pressing the pressure plate 2 firmly. This means the pressure plate 2 is stably mounted on the rotating shaft 41 by the locking screw 42. The rotation of the rotating shaft 41 changes the installation direction of the pressure plate 2. When turning pages in the textbook, the pressure plate 2 can be rotated open first, and then rotated back to its original position after the page is turned, facilitating page turning during teaching and making the textbook more convenient to use.

[0026] More specifically, the floating component 4 also includes a floating spring 43. In this case, the end of the mounting hole near the protruding shaft 41 is a constricted structure, creating a limiting structure at the opening of the mounting hole near the pressure plate 2. The end of the shaft 41 located inside the mounting hole has a protruding retaining edge 411, also creating a limiting structure at that end. Furthermore, the floating spring 43 is placed inside the mounting hole and fitted onto the shaft 41. Both ends of the floating spring 43 abut against the constricted structure of the mounting hole and the retaining edge 411, respectively. The length of the shaft 41 extending outside the mounting hole is adjusted by the extension and retraction of the spring, thereby making the height of the pressure plate 2 adjustable. This not only facilitates page turning in the textbook but also allows the pressure plate 2 to accommodate a wider range of textbook thicknesses, resulting in a more rational structural design.

[0027] More specifically, the floating component 4 also includes a support sleeve 44. During installation, the support sleeve 44 is fitted onto the end of the rotating shaft 41 that extends outside the mounting hole, and one end of the support sleeve 44 abuts against the pressure plate 2. Through the support of the support sleeve 44, there is a gap between the pressure plate 2 and the corresponding upper clamping plate 11 or lower clamping plate 12, so that the end of the pressure plate 2 does not completely stick to the surface of the upper clamping plate 11 or lower clamping plate 12, making it easier for the user to operate the clamping plate 1 to rotate or adjust its height with their fingers, making it more convenient to use.

[0028] The textbook holder provided in this embodiment includes a clamping plate 1 and a telescopic frame 3. By providing pressure plates 2 on both the upper clamping plate 11 and the lower clamping plate 12 of the clamping plate 1, and by providing the telescopic frame 3 between the upper clamping plate 11 and the lower clamping plate 12, when the textbook is placed between the upper clamping plate 11 and the lower clamping plate 12, the pressure plates 2 on the upper clamping plate 11 and the lower clamping plate 12 can press the top and bottom of the textbook paper firmly, preventing the opened textbook from automatically closing, thus facilitating teaching. Simultaneously, by pressing the top and bottom of the textbook, the problem of the textbook paper tilting and affecting viewing is effectively prevented. Furthermore, the distance between the upper clamping plate 11 and the lower clamping plate 12 can be adjusted by extending and retracting the telescopic frame 3, thereby adapting to the clamping needs of textbooks of different lengths, improving adaptability, making the structure more flexible, and facilitating storage and carrying.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
