Referring to fig. 3 to 5, in some embodiments of the present application, the lecture table includes a linkage 24 and a background plate 25, wherein the background plate 25 is slidably mounted on an outward side of the mounting frame 21 in a direction opposite to the extension and retraction of the limiting groove plate 22; the back of the background plate 25 is connected with the input end of a linkage mechanism 24, and the output end of the linkage mechanism 24 is respectively connected with the two groups of limiting groove plates 22; the background plate 25 slides into the mounting window 11 to push the two sets of limiting groove plates 22 out of the mounting window 11 through the linkage 24. The main purpose of the linkage 24 and the background plate 25 is to quickly extend the limiting slot plate 22 when the limiting slot plate 22 is used to clamp an electronic product or a card, and to keep the appearance of the whole speech table top. In this embodiment, after the background plate 25 is connected to two sets of the limiting groove plates 22 through the linking mechanism 24, the above structure forms a linked main body, so that the limiting groove plates 22 can be conveniently drawn out from the mounting frame 21 by a user, and the moving direction of the background plate 25 is opposite to the moving direction of the limiting groove plates 22, so that after the limiting groove plates 22 are extended, the region where the background plate 25 is located is recessed inward, and at this time, the region where the background plate 25 is located forms a region capable of accommodating the protruding back surface of the electronic product device, so that the limiting groove plates 22 do not need to be extended too much to clamp the electronic product. In the existing electronic device, for example, the thickness of a flat or large-screen mobile phone is about 10mm, so that the background plate 25 does not need to protrude too much inwards in practical use, and the limiting groove plate 22 does not need to protrude too much, thereby being more beautiful in appearance. The linkage 24 may be designed with two outputs in the present application, or may be designed such that two sets of limiting slot plates 22 share one output.

With further reference to fig. 3 to 5, the linkage 24 includes a pushing rod 241 and a lever 242, and one end of the pushing rod 241 is hinged to the back of the background plate 25; two groups of levers 242 are provided, two groups of levers 242 are rotatably mounted on the mounting frame 21, one end of each group of levers 242 is hinged to the other end of the pushing rod 241, and the other ends of the two groups of levers 242 are hinged to the limiting groove plates 22 on the corresponding side. It should be noted that, in the present application, the middle portion of the lever 242 is designed such that after the background plate 25 slides inwards in a concave manner, the other end of the lever 242 is necessarily linked with the limiting groove plate 22 by the pushing rod 241 forcing the lever 242 to rotate around its own rotation center, and in the present application, the limiting groove plate 22 is pushed to protrude outwards, so that the limiting groove plate 22 can be pushed to move outwards by the other end of the lever 242. It should be noted that, in order to achieve reasonable utilization of space, the lever 242 may be designed as a V-shaped block with a large angle, and in order to better enable the limiting slot plate 22 to move outwards, the end of the lever 242 hinged to the limiting slot plate 22 may be designed with a movable slot. Because of the limitation of the movement space in practice, if the lever 242 is directly hinged with the limiting slot plate 22, a relatively large space is needed, and for this reason, in another embodiment of the present application, the lever 242 is hinged with the limiting slot plate 22 through a connecting rod, so that through the intermediate transmission of the connecting rod, the problem that the space needed by the lever 242 and the limiting slot plate 22 to move respectively on different planes is too large is avoided. In some embodiments of the present application, the end of the lever 242 hinged to the pushing rod 241 may be directly hinged to the back of the background plate 25, which may save more space, but such a design may have motion stagnation, and this solution is not adopted in the present application. Of course, in the present application, the end of the lever 242 hinged to the limiting slot plate 22 is a long waist hole, and the limiting slot plate 22 is hinged to the corresponding end of the lever 242 by means of a pin passing through the long waist hole, so that there is enough space for movement between the whole lever 242 and the limiting slot plate 22 to avoid movement jamming. In a similar way, in order to avoid the clamping stagnation of the mutual movement of the pushing rod 241 and the lever 242, the movable slotted hole, such as a long waist hole, is also designed at the end where the pushing rod 241 is connected with the lever 242, and the two groups of levers 242 can be jointly installed in the movable slotted hole at the tail end of the pushing rod 241, so that the flexible movement is ensured without clamping stagnation.

Further, in an embodiment of the present application, the upper side and the lower side of the mounting frame 21 are provided with sliding grooves 26, and the limiting groove plate 22 is movably inserted into the sliding grooves 26, so that the whole limiting groove plate 22 can slide more easily and is not easy to generate movement clamping stagnation, and meanwhile, the accuracy of the movement direction is also ensured.

With further reference to fig. 5, in order to better enable the limiting groove plate 22 to retract to keep the whole area inside the installation window 11 neat, beautiful and flat when the fixing device 2 is not used, the upper and lower ends of the outward side of the installation frame 21 are provided with steps 27 for accommodating the hooks 23. Correspondingly, in this application, after the hook portion 23 of the background plate 25 is retracted to the step 27, the background plate 25 is ejected outwards, and after the hook portion 23 is completely retracted to the position, the outer end of the hook portion 23 is flush with the plane of the installation window 11, and simultaneously the background plate 25 is also flush with the plane of the installation window 11, so that the whole lecture table is neat and beautiful. Of course, the outward side of the mounting frame 21 is flush with the plane of the mounting window 11, so that when the fixing device 2 of the present application is not used, the body of the lectern body 1 on the side of the mounting window 11 is substantially planar.

Referring to fig. 4 and 5, in order to make the background plate 25 slide better, in one embodiment of the present application, slide rails 28 are provided on both sides inside the mounting frame 21, and both sides of the background plate 25 are slidably mounted on the slide rails 28 by slide blocks.

Referring to fig. 3 and 5, the speech table of the present application is used according to the following principle, when a user needs to fix a desk card or an electronic device, such as a tablet or a mobile phone, the user only needs to press the background plate 25, the background plate 25 moves inward, at this time, the pushing rod 241 moves inward synchronously, and further drives the lever 242 to rotate around the pushing rod, and the other end of the lever 242 necessarily swings outward, that is, the other end of the lever is opposite to the power input end; at this time, by pushing the connecting rod to move outward, the connecting rod pushes the limiting groove plate 22 on the corresponding side to extend outward, and the amount of extension is determined by the amount of inward movement of the background plate 25, which is determined by the user. When the two limiting groove plates 22 extend outwards for a sufficient distance synchronously, a user can clamp information display articles such as a flat plate, a mobile phone, a card and the like between the two limiting groove plates 22. If the two limiting groove plates 22 are extended by too large a distance, the two limiting groove plates 22 can be pressed to retract inwards, and the background plate 25 is reset outwards accordingly. When the installation window is not used, an operator only needs to take out information display products such as a board, a mobile phone and even a card, and only needs to press the hook part 23 on any limiting groove plate 22 inwards, so that the hook part 23 can return to the ladder 27, meanwhile, the background plate 25 resets, the area where the whole installation window 11 is located is flat and smooth, and the appearance is kept attractive.

The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
