[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 6As shown, the present invention provides a multimedia podium, including a multimedia support column body 1, a podium body 2 is arranged on the outer side of the multimedia support column body 1, and the multimedia support column body 1 passes through the podium body 2 and is fixedly connected to the inner side of the podium body 2, and the inner cavity wall of the podium body 2 is movably connected with two mutually symmetrical adjustment shells 3, a placement groove 15 is opened at the bottom end of the adjustment shell 3, a support leg 16 is arranged on the inner side of the placement groove 15, and the end of the support leg 16 close to the placement groove 15 is rotatably connected to the placement groove 15 through a rotating shaft.

[0021] The above solution is adopted: by manually pulling out the two limit plates 17 from the inside of the podium body 2, the use area of ​​the podium is increased, and when the limit plates 17 are pulled out, the support legs 16 stuck in the placement grooves 15 will pop out to allow the support legs 16 to contact the ground to support the adjustment shell 3.

[0022] like Figure 3 and Figure 4 As shown, two mutually symmetrical retraction springs 6 are arranged inside the podium body 2, and the adjustment shell 3 is elastically connected to the podium body 2 through the retraction spring 6. Two mutually symmetrical sliding grooves 5 are provided on the bottom surface of the podium body 2. The inner side of the sliding groove 5 is movably connected to the limit block 4, and the limit block 4 is fixedly connected to the bottom surface of the adjustment shell 3, and the contact surface between the limit block 4 and the sliding groove is set to be smooth.

[0023] The above scheme is adopted: the adjustment shell 3 after opening is reset and pulled by the elasticity of the retraction spring 6, which is more convenient without manual pushing. The limit block 4 and the sliding groove 5 are arranged to cooperate with each other so that the adjustment shell 3 can be limited when the adjustment shell 3 is pulled manually to prevent the adjustment shell 3 from detaching from the podium body 2 and making the adjustment shell 3 unusable. The contact surfaces of the limit block 4 and the sliding groove 5 are arranged to be smooth, so that the friction force of the limit block 4 is reduced when the limit block 4 slides inside the sliding groove 5, making the limit block 4 more stable when moving.

[0024] like Figures 1 to 4 As shown, a fixing block 18 is fixedly connected to the bottom end of the podium body 2, and two symmetrical mounting plates 19 are fixedly connected to the side of the fixing block 18 away from the podium body 2. A fixing column 9 is movably connected inside the mounting plate 19, and a clamping block 8 is fixedly installed on one end of the fixing column 9 close to the adjustment shell 3. A plurality of limiting grooves 7 are provided on the side of the adjustment shell 3 close to the clamping block 8, and the adjustment shell 3 is clamped with the clamping block 8 through the limiting grooves 7. The adjustment shell 3 fits with the inner side of the podium body 2, and the contact surface between the podium body 2 and the adjustment shell 3 is set to be smooth.

[0025] The above scheme is adopted: by setting the mutual cooperation between the limit groove 7 and the clamping block 8, the clamping block 8 will limit the adjustment shell 3 when the adjustment shell 3 is manually pulled out for use, preventing the adjustment shell 3 from resetting and causing stretching failure, and setting the adjustment shell 3 to fit with the inner side of the podium body 2 to make the adjustment shell 3 more stable when moving inside the podium body 2, and setting the contact surface between the podium body 2 and the adjustment shell 3 to be smooth, so that it is more labor-saving for humans to pull and pull the adjustment shell 3, and setting the mounting plate 19 can increase the distance between the clamping block 8 and the podium body 2. Insufficient placement distance leads to the inability to separate from the limit groove 7, making the cooperation between the clamping block 8 and the limit groove 7 more reasonable.

[0026] like Figure 5 As shown, threaded springs are arranged on the outer sides of the two fixing columns 9, the clamping block 8 is elastically connected to the mounting plate 19 through the threaded springs, a rotation groove 10 is opened at one end of the fixing column 9 away from the adjustment shell 3, a prying rod 11 is rotatably connected inside the rotation groove 10, a fixing plate 12 is fixedly connected to one side of the mounting plate 19 close to the prying rod 11, and the fixing plate 12 is rotatably connected to the middle end of the prying rod 11.

[0027] The above scheme is adopted: by setting the mutual cooperation between the prying rod 11 and the fixed column 9, so that the end of the prying rod 11 away from the rotating groove 10 is subjected to force, and the prying rod 11 presses down the fixed column 9 and the clamping block 8 with the contact point of the fixed plate 12 as the center, so that the adjustment shell 3 is disengaged from the clamping position and the adjustment shell 3 is reset.

[0028] like Figure 5 As shown, one side of the clamping block 8 is set to an oblique angle, and the contact surface between the clamping block 8 and the limiting groove 7 is set to be smooth, the fixing column 9 is set to be square, and the contact surface between the fixing column 9 and the mounting plate 19 is set to be smooth.

[0029] The above scheme is adopted: by setting the clamping block 8 to an oblique angle, the limiting groove 7 can prevent getting stuck when pulling, setting the contact surface between the clamping block 8 and the limiting groove 7 to be smooth to reduce the friction, making it easier for workers to pull, and setting the fixing column 9 to be square to make it more stable when the fixing column 9 drives the clamping block 8 to move.

[0030] like Figure 2 and Figure 4 As shown, a pressing plate 13 is arranged below the fixed block 18, and two symmetrical reset columns 14 are movably connected to the inner side of the pressing plate 13, and one end of the reset column 14 close to the fixed block 18 is fixedly connected to the fixed block 18, and a volute spring is arranged on the outer side of the reset column 14, and the pressing plate 13 is elastically connected to the fixed block 18 through the volute spring, and the side of the pressing plate 13 close to the prying rod 11 is movably connected to the prying rod 11, and the end of the reset column 14 away from the fixed block 18 is fixedly connected with a round block, and the contact surface between the reset column 14 and the pressing plate 13 is set to be smooth.

[0031] The above scheme is adopted: the pressing plate 13 is manually pressed by a person so that the pressing plate 13 is in contact with the two prying rods 11 synchronously, thereby tilting the prying rod 11 for use; after pressing, the pressing plate 13 is reset under the action of the spiral spring to prevent the pressing plate 13 from continuing to contact the prying rod 11, thereby affecting the prying rod 11 from being unable to operate; the pressing plate 13 is limited by setting a round block to prevent the pressing plate 13 from being out of contact with the reset column 14 when not in use, thereby making the pressing plate 13 more stable; the contact surface between the reset column 14 and the pressing plate 13 is set to be smooth to reduce the friction between them, so that it is more labor-saving for humans to press the pressing plate 13.

[0032] like Figure 6 As shown, the placement slot 15 is movably connected to the support leg 16, and the contact surfaces of the placement slot 15 and the support leg 16 correspond to each other. A rubber pad is fixedly provided at one end of the support leg 16 away from the placement slot 15. The contact surface between the placement slot 15 and the support leg 16 is set to be smooth, and the lower end of the support leg 16 is set to be vertical.

[0033] The above scheme is adopted: by setting the placement groove 15 to correspond to the support leg 16, the support leg 16 can just enter the placement groove 15 when the placement groove 15 is contracted, preventing the placement groove 15 from being unable to retract with the support leg 16, and arranging a rubber pad on the placement groove 15 to increase the friction when supporting, making the placement groove 15 more stable when in use, setting the contact surface between the placement groove 15 and the support leg 16 to be smooth to reduce the obstruction and friction when the support leg is placed on the inner side of the placement groove 15, making the support leg 16 more stable when placed, and setting the lower end of the support leg 16 to be vertical so that the force borne by the support leg 16 during support is better transmitted to the ground, thereby improving the supporting effect.

[0034] like Figures 1 to 6 As shown, torsion springs are arranged on both sides of the support legs 16 close to the placement slots 15, and the torsion springs are arranged on the outside of the rotating shaft. The support legs 16 are elastically connected to the placement slots 15 through the torsion springs. One end of the two adjustment shells 3 away from the podium body 2 is fixedly connected to a limit plate 17, and the limit plate 17 is movably connected to the podium body 2. A handle is fixedly installed on the side of the limit plate 17 away from the adjustment shell 3, and the handle is made of rubber material.

[0035] The above scheme is adopted: when the placement slot 15 is extended, the elasticity of the torsion spring drives the supporting leg 16 to stretch until it contacts the ground to complete the support. The limit plate 17 and the podium body 2 cooperate with each other to limit the retracted adjustment shell 3 to prevent the adjustment shell 3 from being unable to be stretched out manually. The handle is made of rubber material to increase the friction when the human grips the handle to pull the limit plate 17 to prevent slipping during the pulling process. The rubber is elastic, which improves the comfort of people when holding it tightly.

[0036] The working principle and use process of the present invention are as follows: when in use, the operator first manually holds the handle, and then pulls the limit plate 17 and the adjustment shell 3 through the handle to adjust the adjustment shell 3 to a suitable area. During the pulling process, the locking block 8 is pushed by the elasticity of the threaded spring to lock the adjustment shell 3 through the limit groove 7, thereby preventing the adjustment shell 3 from resetting during use, causing the adjustment shell 3 to be unusable. While pulling the adjustment shell 3, the support leg 16 will rotate with the torsion of the torsion spring after breaking away from the contact with the podium body 2 until the rubber pad contacts the ground, thereby supporting the pulled adjustment shell 3. When the adjustment shell 3 is pulled to a suitable area, the speech manuscript, books or other materials are placed on the podium. On the main body 2 and the adjustment shell 3, the multimedia is then turned on, and the speaker is allowed to use the multimedia to give a speech. After the speech is finished, the pressing plate 13 is manually pressed to make the prying rod 11 drive the clamping block 8 and the fixing column 9 along the contact point of the rotating groove 10 as the center, thereby making the clamping block 8 disengage from the clamping position of the limiting groove 7. At the same time, the adjustment shell 3 is pulled under the action of the retraction spring 6, and the adjustment shell 3 is pulled back to the inside of the podium main body 2. At the same time, the support leg 16 will also contact the podium main body 2, allowing the support leg 16 to rotate along the rotating shaft until it rotates to the inside of the placement groove 15. At this time, the support leg 16 and the adjustment shell 3 will be reset at the same time, and then the support leg 16 and the adjustment shell 3 will be retracted.
