[0001] This utility model relates to the field of presentation technology, specifically to a portable stand for presentations. Background Technology
[0002] Books are often used to hold them in place during teaching or lecturing to help teachers or speakers.
[0003] Existing portable stands for presentations, such as the one disclosed in authorization announcement number CN221902834U, are for English major teaching presentations. The height of the support plate is adjusted by a telescopic column sliding inside the fixed cylinder in conjunction with a limiting bolt, and the fixed cylinder is supported by a support plate. However, it is inconvenient to fold and shrink the whole, which reduces the overall convenience when moving. At the same time, it uses a clamping mechanism to fix the pages, but since different books have different sizes, it is inconvenient to clamp smaller books. Utility Model Content
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A portable stand for presentations includes an adjusting column, a support assembly movably mounted on the outside of the adjusting column, a connecting seat fixedly mounted on the top of the adjusting column, a tray movably mounted on the inside of the connecting seat, a locking bolt penetrating the tray movably mounted on the outside of the connecting seat, a clamping assembly fixedly mounted on the front of the tray, the support assembly including a sleeve movably fitted onto the outside of the adjusting column and a fixed sleeve, the fixed sleeve being fixedly connected to the top of the sleeve, a locking bolt threaded onto the outside of the fixed sleeve, mounting grooves equidistantly formed on the outside of the sleeve, a support leg movably hinged inside the mounting groove, a limit block fixedly mounted inside the mounting groove, and a strap fixedly mounted on the outside of the support leg.
[0006] A further improvement of the present invention is that the clamping assembly includes a baffle fixedly connected to the lower front side of the tray. The baffle has an installation hole on its inner side. A rotating shaft is movably installed inside the installation hole. Torsion springs are movably engaged with the outer sides of both ends of the rotating shaft. The torsion springs are movably engaged with the inner side of the installation hole. A pressure plate is movably engaged with the outer side of the rotating shaft. A handle is fixedly connected to the top of the pressure plate.
[0007] A further improvement of this utility model is that: the mounting groove is located inside the sleeve and is arranged in a ring at equal intervals.
[0008] A further improvement of this utility model is that the limiting block is located above the support leg, and the inner side of the limiting block is inclined.
[0009] A further improvement of this utility model is that the length of the support leg is less than that of the adjusting column.
[0010] A further improvement of this utility model is that the inner and outer sides of the strap are fixedly connected with matching Velcro.
[0011] A further improvement of this utility model is that the pressure plate is arranged in a "U" shape, and the handles are arranged on the left and right sides of the front side of the pressure plate.
[0012] A further improvement of this utility model is that a groove is provided in the middle of the front side of the tray.
[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0014] 1. This utility model provides a portable stand for presentations. The stand is moved to the upper end of the adjusting column by means of a sleeve and a fixing sleeve. The legs are rotated inward along the mounting groove so that the legs fit against the outside of the adjusting column. The support components are bound to the outside of the adjusting column by wrapping the straps tightly around the legs and the outside of the adjusting column, thereby reducing the overall volume. The overall portability is improved by the hollow design of the adjusting column and the legs.
[0015] 2. This utility model provides a portable stand for presentations. The bottom of the book is supported by a baffle. Torsion springs at both ends of the rotating shaft connected to the pressure plate are locked between the mounting hole and the rotating shaft to provide torsional elasticity. This causes the rotating shaft to drive the pressure plate to rotate and press the pressure plate against both sides of the book pages for clamping. By pulling up the handle, the pressure plate is flipped outward to turn the pages of the book, thus ensuring that books of different sizes can be clamped and fixed. Attached Figure Description

[0022] The present invention will now be described in further detail:
[0023] like Figures 1 to 5 As shown, this utility model provides a portable stand for presentations, including an adjusting column 1, a support component 2 movably mounted on the outside of the adjusting column 1, a connecting seat 3 fixedly mounted on the top of the adjusting column 1, a tray 4 movably mounted on the inner side of the connecting seat 3, a locking bolt 5 movably mounted on the outer side of the connecting seat 3 penetrating the tray 4, a clamping component 6 fixedly mounted on the front side of the tray 4, the support component 2 including a sleeve 21 movably sleeved on the outside of the adjusting column 1 and a fixing sleeve 22, the fixing sleeve 22 being fixedly connected to the top of the sleeve 21, a locking bolt 23 threaded on the outer side of the fixing sleeve 22, mounting grooves 24 being equidistantly opened on the outer side of the sleeve 21, a support leg 25 being movably hinged inside the mounting groove 24, a limit block 26 being fixedly mounted inside the mounting groove 24, and a strap 27 being fixedly mounted on the outer side of the support leg 25.
[0024] The support leg 25 is moved to the upper end of the adjusting column 1 by the sleeve 21 and the fixing sleeve 22, and rotated inward along the mounting groove 24 so that the support leg 25 fits against the outside of the adjusting column 1. The support assembly 2 is bound to the outside of the adjusting column 1 by wrapping the strap 27 tightly around the outside of the support leg 25 and the adjusting column 1, thereby reducing the overall volume. The hollow setting of the adjusting column 1 and the support leg 25 further improves the overall portability.
[0025] like Figure 4 As shown, the clamping assembly 6 includes a baffle 61 fixedly connected to the lower front side of the tray 4. The inner side of the baffle 61 has a mounting hole 62. A rotating shaft 63 is movably installed inside the mounting hole 62. Torsion springs 64 are movably engaged with the outer sides of both ends of the rotating shaft 63. The torsion springs 64 are movably engaged with the inner side of the mounting hole 62. A pressure plate 65 is movably engaged with the outer side of the rotating shaft 63. A handle 66 is fixedly connected to the top of the pressure plate 65.
[0026] The bottom of the book is supported by the baffle 61. The torsion springs 64 at both ends of the rotating shaft 63 connected to the pressure plate 65 are locked between the mounting hole 62 and the rotating shaft 63 to provide torsional elasticity. This causes the rotating shaft 63 to drive the pressure plate 65 to rotate, so that the pressure plate 65 presses against both sides of the book page to clamp it. By pulling up the handle 66, the pressure plate 65 is turned outward to turn the pages of the book, thus ensuring that books of different sizes can be clamped and fixed.
[0027] like Figure 3 As shown, the mounting slots 24 are arranged in a ring at equal intervals inside the sleeve 21.
[0028] The multiple mounting slots 24, with their internal support legs 25, ensure stable support for the adjusting column 1.
[0029] like Figure 3 As shown, the limiting block 26 is positioned above the support leg 25, and the inner side of the limiting block 26 is inclined.
[0030] The limiting block 26 has an inclined inner side and is located above the support leg 25, so that when the support leg 25 rotates, its outer wall is in contact with the inner side of the limiting block 26 to limit the opening angle of the support leg 25.
[0031] like Figure 5 As shown, the length of the support leg 25 is less than that of the adjusting column 1.
[0032] By setting the length of the support leg 25 to be less than that of the adjustment column 1, the support leg 25 is attached to the outside of the adjustment column 1 when moving, thus improving portability.
[0033] like Figure 3 As shown, the inner and outer sides of the strap 27 are fixedly connected with matching Velcro 28.
[0034] By using Velcro 28, the support leg 25 is secured to the outside of the adjustment column 1 and the support leg 25 by wrapping the strap 27 around the adjustment column 1 and the support leg 25 with Velcro 28, thus preventing them from coming apart.
[0035] like Figure 4 As shown, the pressure plate 65 is arranged in a "U" shape, and the handles 66 are located on the left and right sides of the front of the pressure plate 65.
[0036] The U-shaped pressure plate 65 ensures that the pages on both sides are pressed tightly while reducing obstruction.
[0037] like Figure 4 As shown, a groove 41 is provided in the middle of the front side of the tray 4.
[0038] The groove 41 allows the spine of the book to be placed within it, ensuring that the book is placed flat.
[0039] The working principle of the portable stand used in this presentation will be explained in detail below.
[0040] like Figures 1 to 5 As shown, the angle of the tray 4 is adjusted by rotating the tray 4 within the connecting seat 3 and fixing it by tightening the locking bolt 5. The height of the tray 4 is adjusted by sliding the adjusting column 1 up and down within the sleeve 21 and the fixing sleeve 22 and locking it by tightening the locking bolt 23. A book is placed on the tray 4, and the spine of the book is held in place by the groove 41. The bottom of the book is supported by the baffle 61. The torsion springs 64 at both ends of the rotating shaft 63 connected to the pressure plate 65 are engaged between the mounting hole 62 and the rotating shaft 63 to provide torsional elasticity, thereby causing the rotating shaft 63 to drive the pressure plate 65 to rotate. 5. Press the pressure plate 65 on both sides of the book page to clamp it. Pull up the handle 66 to turn the pages of the book by flipping the pressure plate 65 outward. When moving, loosen the sleeve 21 and the fixing sleeve 22 to move it to the upper end of the adjusting column 1 and then tighten the locking bolt 23 to fix it. Rotate the support leg 25 inward along the mounting groove 24 to make the support leg 25 fit against the outside of the adjusting column 1. By wrapping the strap 27 tightly around the outside of the support leg 25 and the adjusting column 1 and using Velcro 28 to fix it, the support component 2 is bound to the outside of the adjusting column 1, thereby reducing the overall volume. Moreover, both the adjusting column 1 and the support leg 25 are hollow, which makes them lighter and improves their portability.
[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
