DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, an adjustable preaching platform includes a base 1, a connecting sleeve 2 is fixedly connected to the middle of the upper end of the base 1, and a lifting component 3 for height adjustment is arranged at the upper end of the connecting sleeve 2. The lifting component 3 includes a sleeve 301, a cylinder 302, a connecting rod 303, a piston 304, a support rod 305, an adjusting rod 306 and a valve bolt 307. The upper end of the sleeve 301 is slidably connected to the cylinder 302, the middle end of the sleeve 301 is fixedly connected to the connecting rod 303, and the top of the connecting rod 303 is provided with a piston 30 4. The upper end of the cylinder 302 is fixedly connected to a support rod 305, and the lower front side of the support rod 305 is movably connected to an adjustment rod 306. The bottom of the adjustment rod 306 is provided with a valve bolt 307. The valve bolt 307 is opened by the push of the adjustment rod 306, and the upper and lower nitrogen chambers in the cylinder 302 divided by the piston 304 are connected. Since the upper end force is greater than the lower end force, the cylinder 302 rises, so that the connected upper end support rod 305 and the placement table 5 rise with it, playing the role of lifting and lowering adjustment. The upper end of the support rod 305 is fixedly connected to the placement table 5,

[0023] like Figure 1 and Figure 3As shown, the lower ends of the left and right sides of the placement platform 5 are provided with slide grooves 6, and the slide grooves 6 are slidably connected with adjustment wheels 8, and adjustment plates 7 are connected between the adjustment wheels 8. The rear end of the adjustment plate 7 is rotatably connected with a support bar 9, and the adjustment plate 7 can be adjusted by sliding in accordance with the slide groove 6 through the adjustment wheel 8, so as to be placed and used for different use positions. The upper outer end of the base 1 is fixedly connected with a guard plate 4, and a three-sided wrapped guard plate 4 is arranged on the outer side of the upper end of the base 1. On the one hand, it can protect the lifting component 3 placed in the middle to avoid collision and other influences, and on the other hand, it increases the aesthetics of the entire lecture platform. The rear end of the inner side of the placement platform 5 is integrally connected with a limiting tooth 10, and the support bar 9 rotating at the rear end of the adjustment plate 7 can cooperate with the limiting teeth 10 at different positions for support, so as to adjust the adjustment plate 7 to different inclination angles, so as to facilitate the user to place the speech manuscript for use at different angles. Alignment grooves 15 are provided at the left and right ends of the upper surface of the placement platform 5. The left and right ends of the front side of the adjusting plate 7 are slidably connected with a pull rod 13, and a spring 14 is sleeved on the outer side of the rear end of the pull rod 13. A pressure block 11 is fixedly connected to the front end of the pull rod 13, and a rubber pad 12 is bonded to the outer side of the rear end of the pressure block 11. The outer structure size of the pressure block 11 is consistent with the opening structure size of the alignment groove 15. The pressure block 11 is elastically connected to the spring 14 through the pull rod 13. The pressure block 11 is pulled outward to compress the spring 14, so that objects such as speech manuscripts are placed at the rear end of the pressure block 11. When the force is lost, the pressure block 11 is elastically pressed against the surface of the adjusting plate 7 by the elastic action of the internal spring 14 to press the speech manuscript, which is convenient to use. Correspondingly, a flexible rubber pad 12 is bonded to the outer side of the rear end of the pressure block 11 to prevent the hard pressure block 11 from directly contacting soft materials such as speech manuscripts and causing damage.

[0024] A placement slot 16 is provided in the middle of the rear side of the adjustment plate 7 , and the placement slot 16 is consistent with the size of the support bar 9 , so that the support bar 9 can be rotated and stored in the placement slot 16 when not in use.

[0025] In summary, if Figures 1 to 3As shown, when using the adjustable lecture platform, the user first presses down and pushes the adjustment rod 306 according to his own needs, so that the valve bolt 307 opens, and the upper and lower chambers divided by the piston 304 in the cylinder 302 are connected. At this time, the pressure inside the upper and lower air chambers is the same, and the force applied by the air pressure of the upper air chamber to the piston 304 is greater than the force applied by the lower air chamber to the piston 304. At this time, the piston 304 will be pushed downward, and the gas in the lower air chamber will be compressed to flow to the upper air chamber, pushing the air pressure rod as a whole to lengthen, that is, the cylinder 302 and the support rod 305 rise, and the height is adjusted. The user repeatedly pushes the adjustment rod 306 according to his own needs. 06 can control the required height of the placement table 5, and further the user pushes the adjustment plate 7 to flip it open, so that the adjustment wheel 8 slides inside the slide groove 6 to adjust the position where it needs to be placed, and flips the adjustment plate 7 to adjust the inclination angle of the adjustment plate 7 according to its own needs, and limits the position by clamping the support bar 9 in the limit tooth 10, and then compresses the spring 14 by pulling the pressure block 11 outward, and clamps the speech through the pressure block 11 to place it. When the adjustment plate 7 is not needed, the adjustment plate 7 can also be placed steadily on the surface of the placement table 5 by rotating the adjusting wheel 8, which is flexible to use, thus completing the use process of the entire adjustable lecture platform.
