The annular sleeve 301 is sleeved on the inner side of the rotary support mechanism 2. A connecting bar 302 is arranged on the opposite side of the annular sleeve 301, and spring telescopic rods 303 for installing the fixed wheel 304 are arranged on the inner sides of both ends of the connecting bar 302. A spring strip group 305 is arranged on the inner side of the connecting bar 302, and one end of the spring strip group 305 is provided with a hinge rod 306 hinged to the hinge base 307. The inner end of the hinge rod 306 is provided with a clamping guide wheel 308, and the inner end of the clamping guide wheel 308 is provided with a sample test tube 309.

[0022] The central axes of the fixed wheel 304 and the clamping guide wheel 308 are parallel to each other, and the hinge rod 306 and the hinge base 307 are symmetrically distributed with respect to the central axis of the clamping guide wheel 308.

[0023] In this embodiment, when the top cover 1010 is opened, the sample test tube 309 is placed into the annular sleeve 301. Since the central axes of the fixed wheel 304 and the clamping guide wheel 308 are parallel to each other, and the central axes of the spring telescopic rod 303 and the spring strip group 305 are parallel to each other, when the sample test tube 309 drops, with the combined action of the spring telescopic rod 303, the fixed wheel 304, the spring strip group 305, the hinge rod 306, the hinge base 307, and the clamping guide wheel 308, the sample test tube 309 can be effectively positioned.

[0024] The bearing member 1 includes a support pad 101, a shock absorber 102, a support plate 103, a side frame 104, a housing 105, a fixed plug 106, an outer handle 107, a cylinder 108, a flexible pad 109, a top cover 1010, a handle cover 1011, a pneumatic telescopic rod 1012 and an insert piece 1013. The top side of the support pad 101 elastically supports a support plate 103 through a shock absorber 102. A side frame 104 is arranged on the outer side of the support pad 101. A housing 105 is arranged on the top side of the support plate 103, and a top cover 1010 is arranged on the top side of the housing 105.

[0025] In this embodiment, when it is necessary to place a sample, the support pad 101 is used in cooperation with the shock absorber 102 and the support plate 103 to place the device at the location where it is used. Through the mutual cooperation of the support plate 103 and the side frame 104, the housing 105 and the top cover 1010 are effectively placed. After the installation is completed, the handle cover 1011 is pulled to open the top cover 1010.

[0026] One end side of the top cover 1010 is provided with a handle cover 1011. One end of the top cover 1010 is provided with an insertion piece 1013 through the output end of a pneumatic telescopic rod 1012. The inner side of the shell 105 is provided with a fixedly inserted block 106 installed in a sleeved manner, and an outer handle 107 is arranged on the outer side of the fixedly inserted block 106. The inner side of the fixedly inserted block 106 is provided with a cylinder 108, and a flexible pad 109 is arranged at the output end of the cylinder 108.

[0027] In this embodiment, after the sample test tube 309 to be taken is in the discharging position, start the pneumatic telescopic rod 1012 to output power to drive the output end to operate, so that the output power of the pneumatic telescopic rod 1012 can drive the insertion piece 1013 to open the top cover 1010. Then, use the cylinder 108 to output power to drive the output end to perform telescopic operation, so that the output power of the cylinder 108 enables the flexible pad 109 to eject the sample test tube 309 out of the device, facilitating the user to take it.

[0028] The rotary support mechanism 2 includes a gearbox 201, a driving motor 202, a rotary column 203, a central sleeve 204, an inner hole disc 205, an outer hole disc 206, a sieve plate 207, a bottom base 208 and a heating rod 209. The gearbox 201 is arranged on the top side of the top cover 1010, and a driving motor 202 is arranged on one side above the gearbox 201. The output end of the gearbox 201 penetrates through the top cover 1010 and is connected to the rotary column 203 installed with the central sleeve 204.

[0029] In this embodiment, when taking is needed, use the driving motor 202 to output power to drive the output end to operate. After the driving motor 202 outputs power, the gearbox 201 drives to operate, enabling the central sleeve 204 to drive the rotary column 203 so that the inner hole disc 205 or the outer hole disc 206 carries the positioning and clamping member 3 to run to a suitable position.

[0030] The outer side of the central sleeve 204 is provided with an inner hole disc 205, and the outer side of the inner hole disc 205 is provided with an outer hole disc 206 installed in a plug-in manner. The rotary column 203 penetrates through the sieve plate 207 and is movably connected to the bottom base 208 installed with the heating rod 209.

[0031] In this embodiment, then use the handle cover 1011 to close the top cover 1010. After the top cover 1010 is closed, the heating rod 209 on the bottom base 208 is heated as needed to keep the temperature inside the shell 105 stable, facilitating the preservation of the properties of the sample for a long time.

[0032] The working principle of the sample injection tray for this electrolyte analyzer is as follows: When it is necessary to place a sample, the support pad 101 is used in conjunction with the shock absorber 102 and the support plate 103 to place the device at the location where it is to be used. Through the mutual cooperation of the support plate 103 and the side frame 104, the housing 105 and the top cover 1010 are effectively placed. After the installation is completed, the handle cover 1011 is pulled to open the top cover 1010. When the top cover 1010 is opened, the sample test tube 309 is placed into the annular sleeve 301. Since the central axes of the fixed wheel 304 and the clamping guide wheel 308 are parallel to each other, and the central axes of the spring telescopic rod 303 and the spring strip group 305 are parallel to each other, when the sample test tube 309 drops, with the combined action of the spring telescopic rod 303, the fixed wheel 304, the spring strip group 305, the articulated rod 306, the articulated base 307, and the clamping guide wheel 308, the sample test tube 309 can be effectively positioned. Then, the handle cover 1011 is used to close the top cover 1010. When the top cover 1010 is closed, the heating rod 209 on the bottom base 208 performs heating treatment as required to maintain the temperature stability inside the housing 105, facilitating the preservation of the properties of the sample for a long time. When it is necessary to take out the sample, the driving motor 202 outputs power to drive the output end to operate. After the driving motor 202 outputs power, the transmission operation of the gearbox 201 enables the central sleeve 204 to drive the rotating column 203, so that the inner hole disk 205 or the outer hole disk 206 carrying the positioning and clamping member 3 runs to a suitable position. When the sample test tube 309 to be taken out is in the discharging position, the pneumatic telescopic rod 1012 is started to output power to drive the output end to operate, so that the power output by the pneumatic telescopic rod 1012 can drive the insertion piece 1013 to open the top cover 1010. Then, the cylinder 108 outputs power to drive the output end to perform telescopic operation, so that the power output by the cylinder 108 makes the flexible pad 109 push out the sample test tube 309 from the device, facilitating the user to take it out.
