[0057] The clamping platform in the prior art adopts a column plus a linear bearing, which occupies more space in the height direction, thereby making the height of the entire mechanism relatively high and the height travel relatively long, which limits the application of the clamping platform to certain height-restricted mechanisms.

[0058] The following is a preferred embodiment of a lever-type clamping platform provided by the utility model that can solve the above technical problems.

[0059] Please refer to Figure 1 and Figure 2 The preferred embodiment of the utility model provides a lever-type clamping platform, which includes a containing box 11, two supporting plates 12 and a lifting mechanism 13.

[0060] Please refer to Figure 1 , Figure 8 and Fig. 9 An opening 111 is provided on one side of the storage box 11, and the storage box 11 includes a cover plate 112 and a bottom plate 113. The bottom plate 113 is provided with two first through holes 1131, and the two first through holes 1131 are arranged in a horizontal direction.

[0061] Please refer to Figure 1 The two support plates 12 are movably arranged between the cover plate 112 and the bottom plate 113 in the vertical direction, and the two support plates 12 are respectively arranged below the two avoidance grooves 1121.

[0062] Please refer to Figure 2 and Figure 4 The lifting mechanism 13 includes two groups of lifting components 131 and a driving module 132. The two groups of lifting components 131 are respectively located below the two support plates 12. The lifting component 131 includes a first slider 1311, a second slider 1312, a compression spring 1313, a sliding bearing 1314 and an active rotating lever 1315. The two ends of the active rotating lever 1315 are respectively a first end 13151 and a second end 13152. The first end 13151 is rotatably connected to the bottom of the base plate 113, and the second end 13152 is connected to the support plate 12 and swings up and down at the first through hole 1131. The first slider 1311 and the second slider 1312 are slidably arranged at the bottom of the base plate 113 along the same horizontal direction, and the sliding direction of the two is perpendicular to the axial direction of rotation of the active rotating lever 1315. A slide groove 13111 is provided on a side of the first slider 1311 facing the active rotating lever 1315. From the first end 13151 to the second end 13152, the slide groove 13111 is inclined gradually approaching the bottom plate 113. The outer ring of the sliding bearing 1314 is slidably disposed in the slide groove 13111, and the inner ring of the sliding bearing 1314 is connected to the middle of the active rotating lever 1315. The compression spring 1313 is connected between the second slider 1312 and the first slider 1311. The driving module 132 is connected to the second slider 1312, and is used to drive the second slider 1312 to slide, and drive the first slider 1311 to slide through the compression spring 1313, so that the sliding bearing 1314 slides along the slide groove 13111, so that the second end 13152 swings up and down, and then the support plate 12 moves up and down.

[0063] When the lever-type clamping platform of the utility model is used, the second slider 1312 is first driven by the driving module 132 to move in a direction away from the first end 13151, the distance between the second slider 1312 and the first slider 1311 increases, the elastic force of the compression spring 1313 decreases, the support plate 12 moves downward by its gravity, the distance between the support plate 12 and the cover plate 112 increases, the support plate 12 presses the second end 13152 downward, the sliding bearing 1314 slides to the lower position of the slide groove 13111, and forces the first slider 1311 to move in a direction close to the second slider 1312, at this time, the support plate 12 can pass through the opening 1 11 Place the opened book between the two support plates 12 and the cover plate 112, and display the contents on the two pages of the book through the two avoidance grooves 1121; then drive the second slider 1312 to move toward the first end 13151 through the driving module 132, and the elastic force of the compression spring 1313 becomes larger, which pushes the first slider 1311 to move toward the first end 13151, so that the sliding bearing 1314 is located at a higher position of the inclined section, and drives the second end 13152 to move upward, so that the support plate 12 is close to the cover plate 112, so as to lift the two pages of the book upward and stick them to the cover plate 112. The lever-type book clamping platform of the utility model converts the horizontal movement of the first slider 1311 and the second slider 1312 into a larger up and down movement of the second end 13152 of the active rotating lever 1315 through the cooperation of the first slider 1311, the second slider 1312, the compression spring 1313, the sliding bearing 1314, the active rotating lever 1315 and the support plate 12, so that the support plate 12 rises and falls, which can effectively reduce the overall height of the lever-type book clamping platform so that it can be integrated into a height-restricted mechanism, and can also make the support plate 12 elastically squeeze the book to avoid damaging the book, and can also adapt to books of different thicknesses.

[0064] Please refer to Figure 2 , Figure 4 and Figure 5 The active rotating lever 1315 includes a first section 13153 and a second section 13154. The first end 13151 is disposed on the first section 13153, and the second end 13152 is disposed on the second section 13154. The second section 13154 is inclined relative to the first section 13153 toward the direction close to the cover plate 112, and the inner ring of the sliding bearing 1314 is connected to the connection between the first section 13153 and the second section 13154. In the upper structure, the angle between the first section 13153 and the second section 13154 is less than 180 degrees, so that the first end 13151 can be closer to the bottom plate 113, so as to reduce the overall size of the active rotating lever 1315 in the vertical direction, so that the entire lever-type clamping platform is thinner and the occupied space in the vertical direction is reduced.

[0065] Please refer to Figure 6 and Figure 7 The first slider 1311 is provided with a first limiting groove 13112 at one end close to the second slider 1312, and the second slider 1312 is provided with a second limiting groove 13121 at one end close to the first slider 1311.

The compression spring 1313 can be positioned by the first limiting groove 13112 and the second limiting groove 13121 to prevent it from being separated from the first slider 1311 and the second slider 1312.

[0066] Please refer to Figure 6 and Figure 7 The lifting assembly 131 further includes a limiting rod 1316. A positioning groove 13113 is provided at one end of the first slider 1311 away from the second slider 1312. The positioning groove 13113 is communicated with the first limiting groove 13112.

[0074] The working process of the lever-type clamping platform of the preferred embodiment of the utility model is as follows:

[0075] 1. The driving motor 1321 rotates, and the two nuts of the bidirectional screw rod 1325 move toward each other, driving the two second sliders 1312 to move toward each other. In each jacking assembly 131, the distance between the second slider 1312 and the first slider 1311 increases, and the elastic force of the compression spring 1313 decreases. The support plate 12 moves downward by its gravity, and the distance between the support plate 12 and the cover plate 112 increases. The support plate 12 presses the second end 13152 downward, and the sliding bearing 1314 slides to the lower position of the slide groove 13111, and forces the first slider 1311 to move toward the direction close to the second slider 1312.

[0076] 2. Place the opened book between the two support plates 12 and the cover plate 112 through the opening 111, and display the contents of the two pages of the book through the two avoidance grooves 1121;

[0077] 3. The driving motor 1321 rotates in the opposite direction, and the two nuts of the bidirectional screw rod 1325 move away from each other, driving the two second sliders 1312 to move away from each other. The elastic force of the compression spring 1313 increases, which pushes the first slider 1311 to move toward the first end 13151, so that the sliding bearing 1314 is located at a higher position of the inclined section, and drives the second end 13152 to move upward, so that the support plate 12 is close to the cover plate 112, so as to clamp the book between the two support plates 12 and the cover plate 112.

[0078] This completes the working process of the lever-type clamping platform of the preferred embodiment.

[0079] When the lever-type book clamping platform of the utility model is used, the second slider is first driven by the driving module to move in a direction away from the first end, the distance between the second slider and the first slider becomes larger, the elastic force of the compression spring becomes smaller, the support plate moves downward by its gravity, the distance between the support plate and the cover plate becomes larger, the support plate presses the second end downward, the sliding bearing slides to the lower position of the slide groove, and forces the first slider to move in a direction close to the second slider, at which time the opened book can be placed between the two support plates and the cover plate through the opening, and the contents on the two pages of the book can be displayed through the two avoidance grooves; then the second slider is driven by the driving module to move in a direction close to the first end, the elastic force of the compression spring becomes larger, and it pushes the first slider to move in a direction close to the first end, so that the sliding bearing is located at a higher position of the inclined section, and drives the second end to move upward, so that the support plate is close to the cover plate, so as to lift the two pages of the book upward and stick them to the cover plate. The lever-type book clamping platform of the utility model converts the horizontal movement of the first slider and the second slider into a larger up and down movement of the second end of the active rotating lever through the cooperation of the first slider, the second slider, the compression spring, the sliding bearing, the active rotating lever and the support plate, so that the support plate can rise and fall, which can effectively reduce the overall height of the lever-type book clamping platform so that it can be integrated into a height-restricted mechanism, and can also make the support plate elastically squeeze the book to avoid damaging the book, and can also adapt to books of different thicknesses.

[0080] To sum up, although the present invention has been disclosed as above in the form of preferred embodiments, the protection scope of the present invention is not limited thereto, and any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the concept of the technical solution of the present invention, which should be covered by the protection scope of the present invention.
