DETAILED DESCRIPTION

[0030] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is only illustrative and not restrictive. The various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0031] See also Figure 1 and Figure 2 In one embodiment of the present invention, a new type of lecture table 100 is provided. The lecture table 100 has a simple structure, is easy to operate, is convenient for users to use, and has good applicability.

[0032] The lecture table 100 includes: a fixed plate 10, a support frame 20 and an angle adjustment mechanism 30. The support frame 20 is connected to the fixed plate 10, and the fixed plate 10 can be turned over relative to the support frame 20, that is, the side of the fixed plate 10 facing the support frame 20 is connected to the support frame 20, and the fixed plate 10 can be turned over around the part where the fixed plate 10 and the support frame 20 are connected; one end of the angle adjustment mechanism 30 is connected to the support frame 20 and can be rotated relative to the support frame 20, and the other end is connected to the side of the fixed plate 10 facing the support frame 20 and can be rotated relative to the fixed plate 10, and the angle adjustment mechanism 30 is used to adjust the inclination angle of the fixed plate 10.

[0033] It is understandable that if Figure 2 As shown, the portion where the angle adjustment mechanism 30 is connected to the fixing plate 10 is located above the side of the fixing plate 10 facing the support frame 20 , and the portion where the support frame 20 is connected to the fixing plate 10 is located below the side of the fixing plate 10 facing the support frame 20 .

[0034] Please also read Figures 3 to 7 The angle adjustment mechanism 30 includes: a sleeve plate 31 and a connecting plate 32. The end of the sleeve plate 31 away from the support frame 20 is connected to the fixed plate 10 and can rotate relative to the fixed plate 10, that is, the sleeve plate 31 can rotate around the portion where the sleeve plate 31 is connected to the fixed plate 10; the end of the connecting plate 32 away from the fixed plate 10 is connected to the support frame 20 and can rotate relative to the support frame 20, that is, the connecting plate 32 can rotate around the portion where the connecting plate 32 is connected to the support frame 20. The end of the connecting plate 32 away from the support frame 20 is inserted into the sleeve plate 31 and is limitedly matched with the sleeve plate 31, so that the end of the connecting plate 32 away from the support frame 20 is always in the sleeve plate 31. It can be understood that the sleeve plate 31 is sleeved on the circumferential outer side of the connecting plate 32. When the angle of the fixed plate 10 is adjusted, the end of the sleeve plate 31 away from the support frame 20 can gradually approach or move away from the support frame 20 along the length direction of the connecting rod.

[0035] Among them, a limiting rod 40 is installed at the end of the connecting plate 32 away from the support frame 20, and the limiting rod 40 is perpendicular to the connecting plate 32 and the sleeve plate part 31; the sleeve plate part 31 is provided with a first opening 311 along the length direction, and the limiting rod 40 is inserted into the first opening 311, so that the limiting rod 40 can be limitedly cooperated with the sleeve plate part 31, and the connecting plate 32 is limited in the sleeve plate part 31 based on the limiting cooperation between the limiting rod 40 and the sleeve plate part 31 to limit the end of the connecting plate 32 away from the support frame 20.

[0036] The sleeve plate 31 is formed with a plurality of protrusions 312 along the length direction, each protrusion 312 is arranged at a distance from each other on the same side of the first opening 311, and a card interface 313 connected to the first opening 311 is formed between two adjacent protrusions 312. It can be understood that Figure 4 As shown, the shapes of the convex portions 312 are the same, the ends of the convex portions 312 facing the first opening 311 are all oriented in the same direction, and the edges thereof are all arranged in an arc shape.

[0037] Among them, the end of the connecting plate 32 away from the support frame 20 is movably equipped with a first clamping plate 50, and the first clamping plate 50 is located on the side of the connecting plate 32 facing the first opening 311. The side of the first clamping plate 50 facing away from the connecting plate 32 is formed with a clamping portion 51, and the clamping portion 51 is inserted into the first opening 311 and can be clamped with the sleeve plate member 31, that is, when the clamping portion 51 is in the clamping interface 313, it can be clamped with the protrusion 312, so that the end of the connecting plate 32 away from the support frame 20 is fixed on the sleeve plate member 31. It can be understood that a limiting opening (not shown) for limiting the movable range of the first clamping plate 50 is formed on the side of the connecting plate member facing the first opening 311, and the first clamping plate 50 can rotate around the length direction of the clamping portion 51 in the limiting opening.

[0038] Among them, Figure 6 As shown, a first groove 52 is formed on one side of the first clamping plate 50 facing the circumferential side of the limiting rod 40 , and the limiting rod 40 can abut and cooperate with the first groove 52 to prevent the first clamping plate 50 from moving.

[0039] The angle adjustment mechanism 30 includes: a second clamping plate 60, which is mounted on the side of the first clamping plate 50 facing away from the connecting plate 32; the second clamping plate 60 is formed with a second opening 61, and the clamping portion 51 and the limiting rod 40 are both arranged in the second opening 61, so that the second clamping plate 60 can move simultaneously with the first clamping plate 50 and the connecting plate 32. In addition, a second groove 62 is formed on the second clamping plate 60, and the second groove 62 is connected to the second opening 61. When the clamping portion 51 moves into the second groove 62, the limiting rod 40 abuts against the first groove 52 to limit the clamping portion 51 in the second groove 62, thereby preventing the first clamping plate 50 from moving. Preferably, the second clamping plate 60 is made of plastic.

[0040] Among them, the lecture desk 100 also includes: a height adjustment bracket 70 and a panel 80. The height adjustment bracket 70 is installed at one end of the support frame 20 facing away from the fixed plate 10, and is used to adjust the height of the fixed plate 10; the panel 80 is fixedly installed on the side of the fixed plate 10 facing away from the support frame 20, and is used to place the user's handouts, speeches, etc. The panel 80 can be adjusted as the inclination angle of the fixed plate 10 is adjusted.

[0041] The angle adjustment process of the panel 80 in the lecture table 100 provided in the above embodiment can be described as follows:

[0042] When the fixing plate 10 is in a horizontal state, the first clamping plate 50 and the second clamping plate 60 are both located at the end of the sleeve plate 31 away from the support frame 20, the clamping portion 51 is located in the second groove 62, and the limiting rod 40 abuts against the groove edge of the first groove 52 close to the fixing plate 10 to limit the clamping portion 51 in the second groove 62; when the user pulls the panel 80 clockwise, the fixing plate 10 turns clockwise around the part where the support frame 20 and the fixing plate 10 are connected, and the sleeve plate 31 moves in a direction away from the connecting plate 32. At this time, The limiting rod 40 is disengaged from the groove edge of the first groove 52 away from the fixed plate 10 so that the clamping portion 51 can be disengaged from the second groove 62; thereafter, when the clamping portion 51 moves along the length direction of the first opening 311 to the clamping interface 313, the clamping portion 51 will slide into the clamping interface 313 and engage with the protrusion 312. If the user stops pulling the panel 80 clockwise, the clamping portion 51 will always be in the clamping interface 313, so that the connecting rod plate and the sleeve plate 31 are in a fixed state, thereby achieving the purpose of adjusting the inclination angle of the panel 80.

[0043] It can be understood that the staff can pull the panel 80 clockwise so that the ends of the first clamping plate 50 and the second clamping plate 60 away from the fixed plate 10 are both located outside the sleeve part 31. At this time, the clamping portion 51 is located in the second groove 62, and the limiting rod 40 abuts against the groove edge of the first groove 52 close to the fixed plate 10 to limit the clamping portion 51 in the second groove 62; when the user rotates the panel 80 counterclockwise, the fixed plate 10 rotates counterclockwise around the part connecting the fixed plate 10 and the support frame 20. At this time, the clamping portion 51 is always located in the second groove 62 to prevent the clamping portion 51 from falling into the clamping interface 313 and causing the clamping portion 51 to be clamped with the protrusion 312, so that the panel 80 and the fixed plate 10 can be returned to a horizontal state.

[0044] The lecture table 100 provided in the above embodiment can adjust the inclination angle of the fixed plate 10 based on the angle adjustment mechanism 30 by connecting the fixed plate 10 to the support frame 20 in a flippable manner, and connecting the two ends of the angle adjustment mechanism 30 to the support frame 20 and the fixed plate 10 respectively. That is, the angle adjustment mechanism 30 can drive the fixed plate 10 to flip around the portion where the fixed plate 10 is connected to the support frame 20, so as to achieve the purpose of adjusting the inclination angle of the fixed plate 10, so that the user can adjust the angle of the panel 80 according to actual needs, which is convenient for the user to browse the speeches, handouts, etc. on the panel 80, and effectively improves the user's usage effect.

[0045] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
