[0032] See also Figure 1-Figure 7, including four legs 1 and a table top 2, the table top 2 is fixedly installed on the top of the four legs 1, and an extension mechanism is arranged on the side of the table top 2; a height adjustment mechanism is arranged on the bottom of the table top 2; the extension mechanism includes an exhibition board 201, a groove 202, a positioning groove 203, a positioning column 204, a limit frame 205, a sliding block 206, a connecting rod 207, a compression spring 208 and a movable rod 209, two exhibition boards 201 are connected to the right side and the rear side of the table top 2 through hinges, two grooves 202 are respectively opened on the right side and the rear side of the table top 2, and two pairs of positioning grooves 203 are respectively opened on the inner walls of the two grooves 202, One end of the two pairs of positioning posts 204 is respectively arranged inside the two pairs of positioning grooves 203, and the other ends of the two pairs of positioning posts 204 extend to the inside of the two grooves 202 respectively. The two limit frames 205 are respectively fixedly connected to the bottom of the two display boards 201, and the two sliding blocks 206 are respectively slidably connected to the inside of the two limit frames 205. The two sliding blocks 206 are respectively located at the bottom of the two display boards 201. The compression springs 208 are respectively fixedly connected to one side of the two sliding blocks 206, and the other ends of the compression springs 208 are respectively fixedly connected to the inner walls of the two limit frames 205. The movable rod 209 is movable. The movable rod 209 is arranged inside the compression spring 208, one end of the movable rod 209 is fixedly connected to one side of the two sliding blocks 206, and the other end of the movable rod 209 passes through the outside of the two limit frames 205. The end of the movable rod 209 is fixedly connected with a handle 9, and the shape of the handle 9 is a long strip. Through the use of the extension mechanism, the space of the sample table 2 can be expanded to provide a more spacious and comfortable working space, so that the operator can adjust and operate the sample or equipment more conveniently, reducing the discomfort or misoperation caused by the tight space. After the display board 201 is folded and contracted, it can be opened. By pulling the movable rod 209 outward through the handle 9, the movable rod 209 will drive the sliding block 206 to slide outward inside the limit frame 205 and squeeze the compression spring 208. When the sliding block 206 moves outward, it can simultaneously pull the positioning column 204 through the connecting rod 207 to slide inward inside the positioning groove 203 under the limitation of the limit groove 601 and the limit block 602, and move the limit block 602 to the innermost side of the limit groove 601, so as to break away from the parallel limitation of the positioning column 204. Finally, the display board 201 is rotated downward by ninety degrees to fold and put away the display board 201.
[0033] See also Figure 2-Figure 3The height adjustment mechanism includes a bottom leg 301, a cylinder 302, a screw rod 303, a worm wheel 304, a worm 305 and a handle 306. The four bottom legs 301 are movably sleeved on the surfaces of the four legs 1. The two cylinders 302 are respectively arranged on the inner sides of the bottom legs 301. One ends of the two screw rods 303 are movably arranged on the inner walls of the two cylinders 302. The other ends of the two screw rods 303 are connected to the bottom of the table board 2 through bearings. The two worm wheels 304 are respectively threadedly connected to the surfaces of the two screw rods 303. The two worm wheels 304 are respectively rotatably connected to the tops of the two cylinders 302. The worm 305 is meshedly connected to one side of the two worm wheels 304. The handle 306 is installed on one end of the worm 305. When using the sample stage and needing to adjust the height of the table top 2, the staff can rotate the worm 305 through the handle 306. The rotation of the worm 305 can drive the meshing worm wheel 304 to rotate at the top of the cylinder 302. The rotation of the worm wheel 304 can simultaneously drive the threaded screw 303 to rotate inside the cylinder 302 and move upward. The upward movement of the screw 303 can lift the table top 2 and move it upward. At the same time, the support leg 1 will slide upward inside the bottom leg 301, thereby adjusting the table top 2 to different heights according to different research tasks. Flexible height adjustment allows the operator to adjust the height of the sample stage according to personal height, work habits and task requirements, reduce fatigue from bowing or bending for a long time, and improve work comfort.
[0034] See also Figure 2-Figure 3 The tops of the two cylinders 302 are fixedly sleeved with support rings 401, and the two ends of the worm 305 are sleeved with support members 402. The two support members 402 are fixedly connected to the tops of the two support rings 401. With the mutual assistance of the support rings 401 and the support members 402, the worm 305 can be supported and limited. The end limit of the worm 305 can ensure that the worm 305 maintains a stable axial position during work, avoids poor engagement of the worm wheel 304 due to position offset, and thus maintains the transmission accuracy.
[0035] See also Figure 5 A cross groove 501 is provided at the end of the worm gear 305, and a cross block 502 is fixedly connected to the rear end of the handle 306 for use with the cross groove 501. Through the cooperation and connection between the cross block 502 and the cross groove 501, the handle 306 and the worm gear 305 can be flexibly installed or disassembled. The handle 306 can be removed when not in use to prevent misoperation and adjustment of the height of the table top 2.
[0036] See also Figure 6-Figure 7The right side and the back side of the table top 2 are both provided with a limiting groove 601, and the inner wall of the limiting groove 601 is movably connected to the limiting block 602, and the limiting block 602 is respectively fixedly connected to the surface of the two pairs of positioning columns 204, so that the limiting block 602 is used in coordination with the limiting block 602, and the positioning column 204 can be limited inside the limiting groove 601 to prevent the positioning column 204 from rotating inside the positioning groove 203. At the same time, under the coordinated connection between the limiting block 602 and the limiting groove 601, the positioning column 204 can move in parallel when moving.
[0037] See also Figure 6-Figure 7 The inner sides of the two pairs of positioning posts 204 are respectively provided with telescopic springs 7, and the two ends of the telescopic springs 7 are respectively fixedly connected to the inner sides of the two pairs of positioning posts 204. The telescopic springs 7 can push the positioning posts 204 to cooperate with the positioning grooves 203 more quickly, and can push the positioning posts 204 to cooperate with the positioning grooves 203 stably.
[0038] See also Figure 1-Figure 2 A vertical groove 801 is provided on the outer side of the support leg 1, and two pairs of hydraulic rods 802 are connected to the inner wall of the vertical groove 801 through a rotating shaft. The other ends of the two pairs of hydraulic rods 802 are respectively connected to the bottom of the two display panels 201 through the rotating shaft. After being stretched out, the hydraulic rods 802 can provide stable support and positioning for the unfolded display panels 201 with the auxiliary support. After the display panels 201 are folded and contracted, the hydraulic rods 802 can be retracted into the vertical groove 801 to prevent the hydraulic rods 802 from bulging outward and affecting the normal folding and contraction of the display panels 201.
[0039] See also Figure 2 and Figure 4 There are several compression springs 208, which are evenly distributed inside the two limit frames 205. Under the action of multiple compression springs 208, the sliding block 206 can be pushed to move more smoothly, and under the elastic force of the compression springs 208, the two pairs of positioning columns 204 can be indirectly and firmly limited inside the positioning groove 203 to prevent the positioning columns 204 from displacing and rotating inside the positioning groove 203.
[0040] Working principle: when using the table top 2 for chemical research, the display board 201 can be directly lifted downward by ninety degrees. When the display board 201 is lifted, it will drive the mechanism at the bottom to rotate and make the positioning column 204 rotate inside the positioning groove 203. After the positioning column 204 rotates, it can push the positioning column 204 to move inside the positioning groove 203 under the elastic force of the telescopic spring 7. When the positioning column 204 moves inside the positioning groove 203, it can also drive the limit block 602 to slide inside the limit groove 601, and with the assistance of the limit block 602 and the limit groove 601, the positioning column 204 can be limited inside the positioning groove 203, thereby the connecting rod 207 can be used to assist in supporting the sliding block 206 and the unfolded display board 201, so that the area of the table top 2 can be increased under the action of the unfolded display board 201, and the expanded desktop space can effectively allocate and arrange experimental equipment, samples and tools, increase the desktop space according to actual needs, and adapt to experimental research requirements of different scales.
