[0031] The specific settings and functions of the limiting device 3 and the adjusting device 4 are described in detail below.
[0032] like Figure 2 and Figure 3As shown, the limiting device 3 includes a slide groove 301, the slide groove 301 is opened on the surface of the table top 5, the inner wall of the slide groove 301 is slidably connected to the slider 302, the inner wall of the slider 302 is slidably connected to the support rod 306, the inner wall of the slider 302 is threadedly connected to the first screw rod 303, one end of the first screw rod 303 is against the inner wall of the slide groove 301, the inner wall of the slider 302 is threadedly connected to the second screw rod 304, one end of the second screw rod 304 is against the surface of the support rod 306, the inner wall of the support rod 306 is rotatably connected to the bidirectional screw rod 308, the circular The arc surface thread is connected with the limit plate 307. When conducting a chemical test, the staff slides the slider 302 in the slide groove 301, rotates the first screw rod 303 to fix the position of the slider 302, pulls the support rod 306 in the slider 302 through the pull ring 305, moves the support rod 306 to a suitable position, rotates the second screw rod 304 to abut against the support rod 306, fixes the support rod 306, thereby adjusting the position of the limit plate 307, and then places the test equipment in the middle of the limit plate 307, rotates the bidirectional screw rod 308, and the bidirectional screw rod 308 drives The limiting plate 307 moves along the round rod 310. The limiting plate 307 clamps the experimental equipment on the table 5 under the drive of the bidirectional screw 308, and limits the experimental equipment to any position on the table. The staff conducts chemical experiments on the table 5. The legs 6 and the bracket 8 support the table 5. The used experimental equipment is rinsed and cleaned in the cleaning tank in the cleaning table 1 through the faucet 2. The surface of the support rod 306 is fixedly connected with the round rod 310. The round rod 310 is slidably connected to the limiting plate 307. The round rod 310 will adjust the moving path of the limiting plate 307. The limit plate 307 is limited to prevent the limit plate 307 from rotating with the bidirectional screw 308, so that the limit plate 307 moves more stably. The surface of the limit plate 307 is fixedly connected with a rubber pad 309. The rubber pad 309 on the limit plate 307 can increase the friction force of the limit plate 307 on the test equipment, so that the limit plate 307 can clamp the test equipment more stably. One end of the support rod 306 is fixedly connected with a pull ring 305. The pull ring 305 is convenient for the staff to pull the support rod 306 to move in the slider 302, so that the staff can adjust the position of the limit plate 307.
[0033] like Figure 4 and Figure 5As shown, the adjusting device 4 includes an adjusting plate 41, which is fixedly connected to the bracket 8, and is slidably connected to the leg 6. A plurality of positioning holes 42 are provided on the surface of the leg 6. A positioning pin 45 is slidably connected to the inner wall of the adjusting plate 41, and a pull block 43 is fixedly connected to one end of the positioning pin 45. The size of the positioning pin 45 matches the size of the positioning hole 42. When the staff needs to conduct a chemical experiment on the table top 5, the staff pulls the pull block 43 to drive the positioning pin 45 to move. When the positioning pin 45 is disengaged from the positioning hole 42, the spring 44 is in a stretched state, and the adjusting plate 41 slides on the leg 6 to move the adjusting plate 41 to a suitable position. The support rod 47 on the adapter block 46 is rotated, and the support rod 47 no longer supports the positioning pin 45. The spring 44 contracts to pull the pull block 43 to move , thereby driving the positioning pin 45 to move and automatically insert it into the positioning hole 42 to limit the adjustment plate 41. The arc surface of the positioning pin 45 is sleeved with a spring 44, one end of the spring 44 is fixedly connected to the adjustment plate 41, and the other end of the spring 44 is fixedly connected to the pull block 43. The spring 44 contracts and pulls the pull block 43 to move, thereby driving the positioning pin 45 to move and automatically insert it into the positioning hole 42 to limit the adjustment plate 41. The contraction of the spring 44 will limit the positioning pin 45 to prevent the positioning pin 45 from falling off from the positioning hole 42. The surface of the pull block 43 is fixedly connected with a transfer block 46, and the inner wall of the transfer block 46 is rotatably connected with a support rod 47. The support rod 47 on the transfer block 46 is rotated, and the support rod 47 supports the pull block 43, so that the positioning pin 45 is limited, which is convenient for the staff to adjust the height of the table board 5.
[0034] Working principle: When conducting a chemical test, the staff slides the slider 302 in the slide slot 301, rotates the first screw rod 303 to fix the position of the slider 302, and pulls the support rod 306 in the slider 302 through the pull ring 305. The pull ring 305 facilitates the staff to pull the support rod 306 to move in the slider 302, and facilitates the staff to adjust the position of the limit plate 307, move the support rod 306 to a suitable position, and rotate the second screw rod 304 to abut against the support rod 306. 6 is fixed to adjust the position of the limit plate 307, and then the test equipment is placed in the middle of the limit plate 307, and the bidirectional screw 308 is rotated. The bidirectional screw 308 drives the limit plate 307 to move along the round rod 310. The round rod 310 limits the moving path of the limit plate 307 to prevent the limit plate 307 from rotating with the bidirectional screw 308, so that the movement of the limit plate 307 is more stable. Driven by the bidirectional screw 308, the limit plate 307 moves the test equipment on the table 5. The rubber pad 309 on the limit plate 307 can increase the friction force of the limit plate 307 on the test equipment, making the limit plate 307 more stable in clamping the test equipment, and limiting the test equipment at any position on the desktop. The staff conducts chemical experiments on the table top 5, and the legs 6 and the bracket 8 support the table top 5. The test equipment after use is rinsed and cleaned in the cleaning tank in the cleaning table 1 through the faucet 2. By setting the limit device 3, when conducting chemical experiments, the container containing chemical substances is placed between the two limit plates 307, and the two-way screw 308 is rotated to drive the limit plate 307 to clamp and limit the container. The test equipment can be fixed at any position on the table top 5 by sliding the slider 302 in the slide groove 301 and the support rod 306 in the slider 302, which effectively prevents the container from falling to the ground due to the staff's accidental collision, thereby improving the staff's fault tolerance in operation and reducing accidents in chemical experiments.
[0035] When the staff needs to conduct a chemical experiment on the table top 5, the staff pulls the pull block 43 to drive the positioning pin 45 to move. When the positioning pin 45 is disengaged from the positioning hole 42, the spring 44 is in a stretched state, and the support rod 47 on the adapter block 46 is rotated. The support rod 47 supports the pull block 43 so that the positioning pin 45 is limited, which is convenient for the staff to adjust the height of the table top 5. The adjustment plate 41 slides on the support leg 6, moves the adjustment plate 41 to a suitable position, and rotates the support rod 47 on the adapter block 46. The support rod 47 no longer supports the positioning The pin 45 supports, and the spring 44 contracts to pull the pull block 43 to move, thereby driving the positioning pin 45 to move and automatically insert it into the positioning hole 42 to limit the adjustment plate 41. The contraction of the spring 44 will limit the positioning pin 45 to prevent the positioning pin 45 from falling off from the positioning hole 42. By setting the adjustment device 4, when the table top 5 is used for chemical experiments, the positioning pin 45 is inserted into the positioning holes 42 at different positions on the support leg 6, so that the height of the table top 5 can be adjusted, so that the workbench can be suitable for workers of different heights, effectively improving the applicability of the workbench.
