DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] like Figures 1 to 4 As shown, a medium-sized volumetric flask ultrasonic extraction fixing device comprises a placing frame 1, a glass window 2 arranged on the outer wall of the placing frame 1, a fixing mechanism 31 is arranged inside the placing frame 1, an adjusting mechanism 32 is arranged on the outer wall of the placing frame 1, the fixing mechanism 31 comprises a placing groove 311 opened at the bottom end of the inner wall of the placing frame 1, a sliding hole is opened on the inner wall of the placing groove 311, a first spring 312 is fixedly connected to the inner wall of the sliding hole, a first sliding rod 313 is fixedly connected to one end of the first spring 312 away from the inner wall of the sliding hole, and the outer wall of the first sliding rod 313 is slidably connected to the inner wall of the sliding hole, The first sliding rod 313 is fixedly connected to the limiting plate 314 at one end away from the first spring 312, and the outer wall of the limiting plate 314 is fixedly connected to the plug plate 315, and the limiting plate 314 is provided with a slot on the other outer wall, and the plug plate 315 is plugged into the inner wall of the slot, and the top of the limiting plate 314 is fixedly connected to the force plate 316, and the bottom end of the inner wall of the placement groove 311 is fixedly connected to the rubber block 317, and the inner wall of the placement frame 1 is provided with an adjustment frame 327, and the top of the adjustment frame 327 is fixedly connected to the fixing column 318, and the outer wall sleeve of the fixing column 318 is provided with a rubber band 319.

[0027] Furthermore, the number of placement frames 1 is six, and the placement frames 1 are distributed in a straight line, so that during the ultrasonic extraction process, the volumetric flasks can be stored in an integrated manner, which makes it easy to centrally transfer the volumetric flasks and use them by the staff.

[0028] Furthermore, there are two limit plates 314, and the volume of the slot provided on the outer wall of the limit plate 314 is larger than the volume of the other limit plate 314 with the plug plate 315 provided on the outer wall. In this way, the limit plate 314 with the plug plate 315 can be covered by the other limit plate 314, so that the plug plate 315 can be plugged into the slot, thereby further improving the stability of the limit plates 314 with each other.

[0029] Furthermore, there are two force-bearing plates 316, which are symmetrically distributed at the top of the two limit plates 314. The outer wall of the end of the force-bearing plate 316 away from the limit plate 314 is provided with a slope that is larger at the top and smaller at the bottom. In this way, when the outer wall of the volumetric bottle contacts its outer wall, the two limit plates 314 can be driven to move away from each other, so as to limit the placement of volumetric bottles of different specifications.

[0030] The adjusting mechanism 32 comprises a fixed frame 321 fixedly connected to the outer wall of the placing frame 1, a through hole is provided on the outer wall of the fixed frame 321, a second sliding rod 322 is slidably connected to the inner wall of the through hole, one end of the second sliding rod 322 is fixedly connected to a dial plate 323, a second spring 324 is fixedly connected to the outer wall of a side of the dial plate 323 connected to the second sliding rod 322, the second spring 324 is fixedly connected to the inner wall of the fixed frame 321 at one end away from the dial plate 323, a positioning rod 325 is fixedly connected to the outer wall of the second sliding rod 322 away from the dial plate 323, a limiting sliding groove is provided on the inner wall of the placing frame 1, a sliding block 326 is slidably connected to the inner wall of the limiting sliding groove, the outer wall of the sliding block 326 is fixedly connected to the outer wall of the adjusting frame 327, a positioning hole is provided on the outer wall of the sliding block 326, and the outer wall of the positioning rod 325 is clamped on the inner wall of the positioning hole.

[0031] Furthermore, the inner wall of the positioning hole formed on the outer wall of the slider 326 fits snugly with the outer wall of one end of the positioning rod 325, thereby ensuring the tightness of the positioning rod 325 after being inserted into the positioning hole, thereby ensuring stability after limiting.

[0032] Furthermore, there are four sliders 326, which are symmetrically distributed on the outer wall of the adjustment frame 327 in a group of two, and the outer wall of the slider 326 fits closely with the inner wall of the limiting groove opened on the inner wall of the placement frame 1, so that the left and right outer walls of the adjustment frame 327 can be supported and slid differently, thereby improving the stability of the adjustment frame 327 during the up and down movement.

[0033] The implementation principle of the ultrasonic extraction fixing device for a medium-sized volumetric flask in this embodiment is as follows: first, the rubber band 319 is moved to one side, and then the volumetric flask is placed in the placement frame 1 through the through hole at the top of the adjustment frame 327. During the placement process, the outer wall of the bottom end of the volumetric flask will first contact the force plate 316, and then the volumetric flask will squeeze the force plate 316 as it continues to move downward. The squeezed force plate 316 will move to the left and right, and at the same time drive the two limit plates 314 and the first slide bar 313 to move. During the movement of the first slide bar 313, the first spring 312 will be squeezed and compressed, so that the two The distance between the limit plates 314 is pulled away until the volumetric flask contacts the bottom end of the placement groove 311 and contacts the rubber block 317. The friction force of the bottom end of the volumetric flask after placement is increased by the rubber block 317 to improve the placement stability. When contacting the rubber block 317, the elastic force of the first spring 312 at this time pushes the limit plate 314 to contact the bottle wall, clamping and limiting the outer wall of the volumetric flask to ensure the stability of the lower part of the volumetric flask after placement. Subsequently, the rubber band 319 at the top is respectively mounted on the outer wall of the upper part of the volumetric flask to limit the upper part of the volumetric flask, thereby completing the placement and limiting effect on the volumetric flask and ensuring stability during the experiment.

[0034] When facing the height of volumetric bottles of different specifications, to adjust the height of the adjustment frame 327, first, the two dial plates 323 are moved toward the middle to drive the second slide bar 322 to move. During the movement of the dial plate 323, the second spring 324 is stretched. At this time, the second slide bar 322 will drive the positioning rod 325 to move toward the middle, so that the positioning rod 325 is separated from the inner wall of the positioning hole opened on the outer wall of the slider 326, thereby releasing the limiting effect on the adjustment frame 327. Subsequently, the adjustment frame 327 can be moved up and down to adjust the height of the adjustment frame 327 to face volumetric bottles of different specifications. After it is raised to a suitable position, the dial plate 323 is released, and the second spring 324 rebounds and resets to push the positioning rod 325 into the positioning hole to complete the positioning effect.
