Description

Technical Field

[0001] The utility model belongs to the technical field of multi-parameter analyzers, in particular to a multi-parameter analyzer capable of quickly replacing sample liquids. Background Art

[0002] As an instrument that can simultaneously measure and analyze multiple parameters, the multi-parameter analyzer is widely used in environmental monitoring, industrial production, scientific research experiments and other fields. It can monitor and record multiple parameters such as temperature, humidity, air pressure, pH value, dissolved oxygen, turbidity, conductivity, etc. in real time, and has functions such as data processing, abnormal alarm, and power-off protection. It is suitable for various occasions such as water quality management, environmental protection, and food safety testing.

[0003] When analyzing and detecting sample liquid, the existing multi-parameter analyzer needs to place the sample liquid in a relatively closed environment for analysis and detection. After the light-shielding door panel and the light-shielding frame are flipped and closed, the light-shielding door panel and the light-shielding frame are tightly closed by relying on the magnetic attraction between the light-shielding door panel and the light-shielding frame. When subjected to external force, the light-shielding door panel is prone to flipping on one side of the light-shielding frame, destroying the relatively closed environment inside the light-shielding frame, thereby affecting the analysis and detection of the sample liquid. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a multi-parameter analyzer that can quickly replace sample liquid, which solves the problem that when the existing multi-parameter analyzer analyzes and detects the sample liquid, the light-shielding door plate is easily flipped on one side of the light-shielding frame, destroying the relatively closed environment inside the light-shielding frame, thereby affecting the analysis and detection of the sample liquid.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-parameter analyzer that can quickly replace sample liquid, comprising an analyzer body, a concave frame embedded and fixedly installed at the central position of the top of the analyzer body, four groups of limit grooves are equidistantly provided at the bottom of the inner bottom of the concave frame, a limit plate is slidably installed at the top of the limit groove, a top rod is fixedly installed on the top of the limit plate, the four groups of top rods are fixedly installed with a trapezoidal clip at one end located at the top of the concave frame, a fixing spring is provided on the surface of the top rod located between the bottom of the trapezoidal clip and the bottom of the concave frame, a light-shielding frame is fixedly installed on the top of the analyzer body, a light-shielding door plate is rotatably installed on the top of the light-shielding frame, a light-transmitting pad is fixedly installed between the bottoms of the two sides of the inner wall of the light-shielding frame, and a fixing plate is provided on the inner wall of the light-shielding frame at the top of the light-transmitting pad.

[0006] As a further solution of the present invention: limiting slide grooves are symmetrically provided on the tops of both sides of the concave frame, limiting protrusions are fixedly installed at both ends of the trapezoidal card strip, and a shift block is fixedly installed on one end of the limiting protrusion passing through the limiting slide groove.

[0007] As a further solution of the present invention: three groups of T-shaped slots are equidistantly provided on the top of the inner wall of the light-shielding frame, and rubber pads are fixedly installed on the bottom of the inner wall of the T-shaped slots.

[0008] As a further solution of the present invention: three groups of T-shaped blocks are fixedly installed at equal intervals on one side of the fixing plate, and the positions of the T-shaped blocks and the T-shaped slots correspond to each other and have the same shape.

[0009] As a further solution of the present invention: a fixed clamping plate is fixedly installed on the top of one side of the fixed plate, and four groups of support bars are fixedly installed at equal distances between the bottom of the fixed clamping plate and the bottom of one side of the fixed plate.

[0010] As a further solution of the present invention: five groups of fixed card slots are equidistantly provided on the surface of the fixed card plate, five groups of placement slots are equidistantly provided on the top of the transparent pad, and the positions of the fixed card slots correspond to the placement slots, and a test tube is provided between the inside of the fixed card slot and the top of the placement slot.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The multi-parameter analyzer capable of rapidly replacing sample liquids is provided with a trapezoidal clamping strip, a fixed spring, a light-shielding frame, and a light-shielding door plate. After a test tube is clamped in the fixed clamping plate inside the light-shielding frame, the light-shielding door plate is flipped over so that one side of the light-shielding door plate slides over the top of the trapezoidal clamping strip, and the trapezoidal clamping strip is pressed into the concave frame until the light-shielding door plate completely passes through the trapezoidal clamping strip. Then, under the rebound action of the fixed spring, the trapezoidal clamping strip is pushed out of the concave frame and clamped on one side of the light-shielding door plate, thereby stably closing the light-shielding door plate and the light-shielding frame, ensuring that the light-shielding door plate will not open arbitrarily on one side of the light-shielding frame, and allowing the test tube to be analyzed and tested in a relatively closed environment.

[0013] 2. The multi-parameter analyzer capable of quickly replacing sample liquids is provided with a rubber card pad, a T-shaped card block, a fixed card plate and a light-transmitting pad. The three groups of T-shaped card blocks on one side of the fixed plate are correspondingly inserted into the T-shaped card slots on the inner wall of the light-shielding frame, so that the rubber card pad is squeezed and deformed on one side of the T-shaped card block, the T-shaped card block is clamped and fixed, and the fixed card plate is clamped and fixed to the top of the light-transmitting pad, so that it is convenient to replace the fixed card plate that is damaged after long-term use, and ensure that the fixed card slot on the surface of the fixed card plate corresponds to the position of the placement slot on the top of the light-transmitting pad. When the test tube is inserted into the fixed card slot, the bottom of the test tube is clamped in the placement slot to support the test tube, thereby preventing the test tube from falling when it is clamped on the surface of the fixed card plate.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a multi-parameter analyzer that can quickly replace sample liquid, comprising an analyzer body 1, a concave frame 2 is embedded and fixedly installed at the central position of the top of the analyzer body 1, four groups of limiting grooves 3 are equidistantly provided at the bottom of the concave frame 2, a limiting plate 4 is slidably installed on the top of the limiting groove 3, a push rod 5 is fixedly installed on the top of the limiting plate 4, and a trapezoidal clamping strip 6 is fixedly installed at one end of the four groups of push rods 5 located at the top of the concave frame 2, and a fixing spring 7 is provided on the surface of the push rod 5 located between the bottom of the trapezoidal clamping strip 6 and the bottom of the concave frame 2. The fixing spring 7 is provided, and the trapezoidal clamping strip 6 is pushed upward under the rebound action of the fixing spring 7 until the trapezoidal clamping strip 6 is pushed out of the concave frame 2 and clamped on one side of the light-shielding door plate 12, and the light-shielding door plate 12 is clamped and fixed to one side of the light-shielding frame 11, so that the light-shielding door plate 12 and the light-shielding frame 11 are closed;

[0022] Limiting grooves 8 are symmetrically provided at the tops of both sides of the concave frame 2, and limiting protrusions 9 are fixedly installed at both ends of the trapezoidal card strip 6, and a shift block 10 is fixedly installed at one end of the limiting protrusion 9 passing through the limiting groove 8. Because of the limiting grooves 8 and limiting protrusions 9, when the trapezoidal card strip 6 moves up and down at the top of the concave frame 2, it drives the limiting protrusion 9 to slide inside the limiting groove 8, thereby limiting the moving range of the trapezoidal card strip 6 at the top of the concave frame 2, preventing the trapezoidal card strip 6 from detaching from the top of the concave frame 2.

[0023] A light-shielding frame 11 is fixedly installed on the top of the analyzer body 1. Three groups of T-shaped slots 15 are equidistantly provided on the top of the inner wall of the light-shielding frame 11. A rubber pad 16 is fixedly installed on the bottom of the inner wall of the T-shaped slot 15. By providing the rubber pad 16, when the T-shaped card block 18 is inserted into the T-shaped slot 15 and is tightly attached to the rubber pad 16, the rubber pad 16 is squeezed and deformed on the surface of the T-shaped card block 18, thereby clamping and fixing the T-shaped card block 18 inside the T-shaped slot 15.

[0024] A light-shielding door panel 12 is rotatably installed on the top of the light-shielding frame 11, and a light-transmitting pad 13 is fixedly installed between the bottoms on both sides of the inner wall of the light-shielding frame 11. Five groups of fixed card slots 21 are equidistantly provided on the surface of the fixed card plate 19, and five groups of placement slots 14 are equidistantly provided on the top of the light-transmitting pad 13, and the positions of the fixed card slots 21 and the placement slots 14 correspond to each other. A test tube 22 is provided between the inside of the fixed card slot 21 and the top of the placement slot 14. Due to the provision of the light-transmitting pad 13 and the fixed card slot 21, the test tube 22 is stuck in the corresponding fixed card slot 21 and padded in the corresponding placement slot 14, ensuring that the test tube 22 is stuck in the fixed card slot 21 without tilting or deflecting. At the same time, the light-transmitting pad 13 supports the test tube 22 to prevent the test tube 22 from falling after being stuck in the fixed card slot 21.

[0025] A fixing plate 17 is provided on the inner wall of the light-shielding frame 11 at the top of the light-transmitting pad 13. Three groups of T-shaped blocks 18 are fixedly installed at equal distances on one side of the fixing plate 17. The T-shaped blocks 18 correspond to the positions of the T-shaped slots 15 and have the same shape. By providing the T-shaped blocks 18, the T-shaped blocks 18 on one side of the fixing plate 17 are inserted into the corresponding T-shaped slots 15 to ensure that the fixing plate 17 will not be misaligned when it is fixed to the inner wall of the light-shielding frame 11.

[0026] A fixed clamping plate 19 is fixedly installed on the top of one side of the fixed plate 17, and four groups of support bars 20 are fixedly installed at equal distances between the bottom of the fixed clamping plate 19 and the bottom of one side of the fixed plate 17. Because of the support bars 20, after the test tube 22 is clamped in the corresponding fixed clamping groove 21, the support bars 20 support the fixed clamping plate 19 to prevent the fixed clamping plate 19 from falling on one side of the fixed plate 17.

[0027] The working principle of this utility model is:

[0028] Press the two sets of dial blocks 10 to drive the trapezoidal card strip 6 to move down at the top of the concave frame 2 away from the shading door plate 12, flip the shading door plate 12 away from the shading frame 11, and insert the T-shaped card block 18 on one side of the fixed plate 17 into the T-shaped card slot 15 corresponding to the inner wall of the shading frame 11, push the fixed plate 17 down, and make the T-shaped card block 18 slide down inside the T-shaped card slot 15 until the T-shaped card block 18 is tightly attached to the rubber card pad 16, so that the rubber card pad 16 is squeezed and deformed, and the T-shaped card block 18 is clamped and fixed inside the T-shaped card slot 15, ensuring that the fixed card plate 19 on one side of the fixed plate 17 is located on the top of the light-transmitting pad 13, so that the surface of the fixed card plate 19 The fixed card slot 21 corresponds to the placement slot 14 on the top of the light-transmitting pad 13, and the test tube 22 containing the sample liquid is inserted into the fixed card slot 21 on the surface of the fixed card plate 19, so that the bottom end of the test tube 22 is stuck in the corresponding placement slot 14, and the light-shielding door plate 12 is flipped over, and one side of the light-shielding door plate 12 is controlled to slide through the top of the trapezoidal card strip 6. Under the rebound action of the fixed spring 7, the trapezoidal card strip 6 can be clamped and fixed to one side of the light-shielding door plate 12, ensuring that the light-shielding door plate 12 is tightly closed with the light-shielding frame 11, and the analyzer body 1 is started to analyze and detect the sample liquid contained in the test tube 22 clamped and fixed inside the light-shielding frame 11.
