DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figures 1 to 3 As shown, the utility model provides a lecture platform, comprising:

[0028] A support 10, a column 20 and a plate 30, wherein the column 20 is connected to the support 10 in a vertical direction, and a through hole is provided on the plate 30 to form a nested connection with the column 20, and the plate 30 and the support 10 are fixed by fasteners, and a gap reduction mechanism 40 is provided between the plate 30 and the column 20 for eliminating the assembly gap therebetween, wherein the gap is provided between the side wall of the column 20 and the hole wall of the through hole, and the gap reduction mechanism 40 includes a first sliding member 41 and a second sliding member 42 connected to adjacent sides of the plate 30, and a wedge-shaped fit is formed between the first sliding member 41 and the second sliding member 42, wherein the movement of the first sliding member 41 causes the second sliding member 42 to move toward the column 20, thereby eliminating the gap between the column 20 and the plate 30, so that the column 20 and the plate 30 are in contact with each other.

[0029] It is worth mentioning that the column 20 and the plate 30 are two assembly parts of the podium, and one of the assembly parts in the column 20 and the plate 30 is fixed, and the other assembly part in the column 20 and the plate 30 is movably arranged, wherein the first sliding member 41 and the second sliding member 42 are arranged on the movably arranged assembly part, and through the wedge-shaped cooperation between the first sliding member 41 and the second sliding member 42, the movably arranged assembly part moves toward the direction of the fixedly arranged assembly part, thereby eliminating the assembly gap between the two assembly parts.

[0030] In addition, in general, the materials of the column 20 and the plate 30 are different, resulting in different manufacturing processes for the two, so that the two have different tolerances after molding, and finally a gap is formed after the two are assembled. For example, the column 20 and the plate 30 mentioned above, wherein the column 20 is generally made of metal, and the plate 30 is generally made of wood. Due to the assembly gap between the column 20 and the plate 30, the column 20 will have a slight shake after the entire product is assembled, affecting the safety of the product when in use. However, through the gap reduction mechanism 40 in this embodiment, the assembly gap between the column 20 and the plate 30 can be reduced or even eliminated, so that the column 20 and the plate 30 are closely abutted against each other, and the column 20 is prevented from shaking, thereby improving the safety of the product during use.

[0031] The utility model provides a lecture platform, which can reduce or even eliminate the assembly gap between the column 20 and the plate 30 through the gap reduction mechanism 40, so that the column 20 and the plate 30 are tightly abutted against each other, avoiding the shaking of the column 20, thereby improving the safety of the product during use. In addition, the gap reduction mechanism 40 eliminates the gap through wedge-shaped cooperation, thereby adapting to gaps of different sizes and improving the versatility of the gap reduction mechanism 40.

[0032] Further preferably, the second sliding member 42 and the first sliding member 41 are arranged up and down along the length direction of the column 20, and the second sliding member 42 and the first sliding member 41 are respectively provided with a first guide bevel 421 and a second guide bevel 411, wherein the first guide bevel 421 cooperates with the second guide bevel 411. In the present embodiment, the first guide bevel 421 cooperates with the second guide bevel 411 and can move relatively. By moving the first sliding member 41 along the length direction of the column 20, the second sliding member 42 moves in a direction close to or away from the column 20, thereby reducing or expanding the gap between the column 20 and the plate 30.

[0033] In this embodiment, a wedge-shaped fit is formed between the second sliding member 42 and the first sliding member 41 through the cooperation and movement between the first guiding bevel 421 and the second guiding bevel 411, so that the gap between the column 20 and the plate 30 is eliminated gradually, thereby improving the tightness of the abutment between the column 20 and the plate 30 and preventing the column 20 from shaking.

[0034] Further preferably, the first sliding member 41 is connected to the lower surface of the plate 30, one end of the second sliding member 42 is connected to the side of the plate 30 facing the column 20, and the other end of the second sliding member 42 is placed on the upper surface of the plate 30, wherein the second sliding member 42 is connected to the side of the plate 30 facing the column 20 to form a wedge-shaped fit with the first sliding member 41.

[0035] It is worth mentioning that when the first sliding member 41 moves upward, due to the wedge-shaped fit between the first sliding member 41 and the second sliding member 42, the second sliding member 42 is pushed to move in the direction close to the column 20. Since the second sliding member 42 is installed on the plate 30, the second sliding member 42 drives the plate 30 to move synchronously in the direction of the column 20 during the movement, thereby eliminating the gap between the plate 30 and the column 20.

[0036] Preferably, two mutually connected mounting grooves are provided on the plate 30, namely a first mounting groove 31 which forms a plug-in fit with the second sliding member 42, and a second mounting groove 32 which forms a sliding fit with the first sliding member 41, wherein one end of the second sliding member 42 which forms a plug-in fit with the first mounting groove 31 extends into the second mounting groove 32, and the wedge-shaped fit formed between the second sliding member 42 and the first sliding member 41 is located in the first mounting groove 31 or in the second mounting groove 32.

[0039] It is worth mentioning that the first sliding member 41 is driven to move up and down by the rotation of the fastener 43, which is easy to operate, and the first sliding member 41 is limited by the shape of the second mounting groove 32, so that the first sliding member 41 will not rotate synchronously with the fastener 43, but can only move in a straight line, thereby ensuring the reliability of the contact between the first sliding member 41 and the second sliding member 42.

[0040] Further preferably, the second sliding member 42 is L-shaped, and a portion of the L-shape is in the gap.

[0041] Further preferably, a first through hole 422 is provided on one end of the second sliding member 42 resting on the plate 30, a second through hole 33 connected to the first through hole 422 is provided on the plate 30, and a threaded hole connected to the second through hole 33 is provided on the first sliding member 41, wherein the first through hole 422, the second through hole 33 and the threaded hole are coaxially arranged, and one end of the fastener 43 passes through the first through hole 422 and the second through hole 33 in sequence, and are threadedly engaged with the threaded hole.

[0042] Preferably, the gap reduction mechanism 40 also includes a nut 44, and the nut 44 is installed on the first sliding member 41, wherein the nut 44 forms a threaded fit with the fastener 43. At this time, the threaded hole originally set on the first sliding member 41 is transferred to the nut 44, which can also realize the up and down movement of the first sliding member 41.

[0043] It is worth mentioning that the nut 44 can be installed on the side of the first sliding member 41 facing the bottom of the second mounting groove 32, or installed on the side of the first sliding member 41 away from the bottom of the second mounting groove 32, wherein, when the nut 44 is installed on the side of the first sliding member 41 away from the bottom of the second mounting groove 32, the first sliding member 41 is provided with a third through hole 412 coaxially arranged with the first through hole 422 and the second through hole 33, and the fastener 43 passes through the first through hole 422, the second through hole 33 and the third through hole 412 in sequence, and forms a threaded fit with the nut 44.

[0044] Further preferably, in order to reduce the longitudinal dimension of the entire gap reduction mechanism 40, a concave cavity 413 connected to the third through hole 412 can be provided on the first sliding member 41, and the opening direction of the concave cavity 413 is consistent with the opening direction of the second mounting groove 32, wherein the nut 44 is connected to the bottom of the concave cavity 413.

[0045] It is worth mentioning that the first sliding member 41 and the nut 44 are integrally arranged.
