[0024] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Refer to the attached Figure 1 and Figure 5 The embodiment of the present invention is a cabinet-type total phosphorus water quality online analyzer, comprising an analyzer body 1, on which a detection area 2 is arranged, a test tube rack 3 is arranged in the detection area 2, the test tube rack 3 is made of polypropylene material, and a plurality of storage holes 4 are evenly opened on the test tube rack 3, and the storage holes 4 are used to store test tubes containing water samples.

[0027] Refer to the attached Figure 5 and Figure 6 A support member 5 is provided at the bottom of the storage hole 4. The support member 5 is used to support the test tube and allow the test tube to have a certain buffer space when it is subjected to vibration or external force to prevent the test tube from breaking. Specifically, the support member 5 includes a top plate 501, a No. 1 spring 502 and a bottom plate 503 arranged in sequence from top to bottom, wherein the No. 1 spring 502 is fixedly installed between the top plate 501 and the bottom plate 503, and the bottom plate 503 is fixedly installed in the storage hole 4. The addition of the No. 1 spring 502 provides a buffer in the vertical direction for the test tube. The top plate 501 is made of sponge material, and the sponge material also has a buffering effect. The combination of the No. 1 spring 502 and the top plate 501 fully realizes the protection of the test tube.

[0028] Refer to the attached Figure 5Two No. 2 springs 6 are symmetrically fixedly installed on the inner wall of the storage hole 4, and a limit frame 7 is fixedly installed on the outer end of the No. 2 spring 6. The No. 2 spring 6 and the limit frame 7 are used in combination to limit the test tube in the horizontal direction, effectively preventing the test tube from shaking or tilting during the detection process. It should be noted that the limit frame 7 is a structure with a wide top and a narrow bottom, so that it plays a guiding role when the test tube is inserted, so that it can smoothly enter the predetermined position. Due to the narrow bottom, it can form a certain clamping effect on the test tube to prevent the test tube from being easily pulled out or falling off without permission, and the structure with a wide top and a narrow bottom can adapt to test tubes of different diameters.

[0029] Refer to the attached Figure 3 The cross section of the limit frame 7 is an arc-shaped structure, which can better adapt to the shape of the test tube and increase the contact area with the test tube, thereby improving the stability of the limit. At the same time, the limit frame 7 is made of rubber material, which can provide a buffer between the test tube and the limit frame 7, reducing the risk of test tube damage caused by direct collision or friction.

[0030] Refer to the attached Figure 2 and Figure 3 Slideways 8 are fixedly installed on both sides of the bottom of the detection area 2, and mounting frames 9 are fixedly installed on the bottom of the test tube rack 3. The width inside the slideway 8 is equal to the width of the mounting frame 9, which ensures the stability of the movement of the test tube rack 3 and prevents the test tube rack 3 from being offset when the operator uses the device. Several rollers 10 are rotatably installed in the mounting frame 9, which makes the movement of the test tube rack 3 in the detection area 2 smoother, reduces friction, and makes the operation easier.

[0031] Refer to the attached Figure 3 A pull-out handle 11 is rotatably mounted on the front of the test tube rack 3. The pull-out handle 11 makes the pull-out operation of the test tube rack 3 more convenient. The pull-out handle 11 is processed with anti-slip grooves. The design of the anti-slip grooves increases the stability of the operation and prevents the test tube rack 3 from accidentally falling off due to hand slipping during use.

[0032] Refer to the attached Figure 4 Buffer pads 13 are fixedly installed on both sides of the rear wall of the test tube rack 3, and the buffer pads 13 are made of rubber material. The setting of the buffer pads 13 can buffer the collision between the rear wall of the test tube rack 3 and the detection area 2 when the test tube rack 3 moves, reduce noise and wear, and protect the integrity of the test tube rack 3 and the detection area 2.

[0033] Refer to the attached Figure 1 and Figure 2A plug-in slot is provided on the side of the analyzer body 1, and a limit baffle 12 is slidably installed in the plug-in slot. When the buffer pad 13 on the rear wall of the test tube rack 3 is in contact with the rear side of the detection area 2, the operator inserts the limit baffle 12 into the plug-in slot. At this time, the limit baffle 12 is just in contact with the front wall of the test tube rack 3, thereby limiting the test tube rack 3 and preventing the test tube rack 3 from sliding out of the detection area 2.

[0034] The present application provides a vertical buffer for the test tube through the design of the support member 5, in combination with the top plate 501 and the No. 1 spring 502, effectively preventing the test tube from breaking when subjected to vibration or external force. The No. 2 spring 6 cooperates with the limit frame 7 of the upper wide and lower narrow structure to limit the test tube in the horizontal direction, reducing shaking and tilting, thereby improving the stability of the test tube. In addition, this design also enables the limit frame 7 to adapt to test tubes of different diameters, increasing the versatility of the instrument.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
