[0006] According to a further technical solution, a spring clip fixing member mounting hole is provided on the spring clip fixing member mounting seat, an M3 flat head screw is provided in the spring clip fixing member mounting hole, and the M3 flat head screw is threadedly connected to the lower end of the spring clip fixing member.

[0007] According to a further technical solution, a protruding positioning boss is provided at the lower end of the spring fixing member mounting seat.

[0008] According to a further technical solution, a mounting hole is provided on the positioning boss.

[0009] A further technical solution is that a cuvette positioning shrapnel fixing hole is provided at the upper end of the shrapnel fixing piece, an M3 machine pan head screw penetrates the cuvette positioning shrapnel, and the M3 machine pan head screw is threadedly connected to the cuvette positioning shrapnel fixing hole.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The utility model provides a long cuvette fixing seat. The product has a simple structure and ensures the repeated positioning accuracy of the long cuvette in the single-hole seat by utilizing the structure of the elastic steel sheet. The product has high repeated positioning accuracy, is durable, easy to install, and has stable performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0018] like Figure 1-Figure 3As shown, a long cuvette fixing seat provided by an embodiment of the present invention includes a spring clip fixing member mounting seat 5, and further includes: two spring clip fixing members 4 fixed to the upper end of the spring clip fixing member mounting seat 5, a spring clip fixing member mounting hole 9 is provided on the spring clip fixing member mounting seat 5, an M3 flat head screw 7 is provided in the spring clip fixing member mounting hole 9, the M3 flat head screw 7 is threadedly connected to the lower end of the spring clip fixing member 4, and the two spring clip fixing members 4 are arranged in parallel; a plurality of cuvette holder fixing holes 6 are provided on the upper end of the spring clip fixing member mounting seat 5; A cuvette positioning spring clip 2 is fixed to the upper end of the spring clip fixing member 4, and a cuvette positioning spring clip fixing hole 3 is provided at the upper end of the spring clip fixing member 4. An M3 machine tooth pan head screw 1 passes through the cuvette positioning spring clip 2, and the M3 machine tooth pan head screw 1 is threadedly connected to the cuvette positioning spring clip fixing hole 3. The cuvette positioning spring clip 2 extends downward between the two spring clip fixing members 4. A protruding positioning boss 8 is provided at the lower end of the spring clip fixing member mounting seat 5, and a mounting hole is provided on the positioning boss 8. At least one cuvette positioning spring clip 2 is installed.

[0019] In the embodiment of the present invention, the long cuvette holder is fixed on the fixing seat of the cuvette holder in the sample chamber of the instrument through the positioning boss 8 and the mounting hole at the bottom of the spring fixing member mounting seat 5. Then, when the long cuvette is placed into the interior of the cuvette holder fixing hole 6, the cuvette positioning spring 2 automatically clamps the cuvette and always keeps the Y-axis in the same position. Since the hardness and fatigue strength of the cuvette positioning spring 2 are very good, the cuvette holder is made of aluminum alloy and the product precision is high, so it can ensure that the cuvette is placed in the same position each time, thereby ensuring the accuracy of the measurement. This product has a simple structure, is easy to assemble, has high precision, and stable performance; it does not affect the optical path during measurement and does not cause light loss.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
