[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The core of the present invention is to provide a reaction cup assembly for an analytical instrument. Each reaction cup is clamped in a reaction cup holder, and the damaged reaction cup can be replaced individually, significantly reducing the replacement cost.

[0028] The reaction cup assembly for an analytical instrument provided by the present invention includes:

[0029] A reaction cup holder 1 for connecting with an analytical instrument, which is provided with at least one row of reaction cup holes 11, and the reaction cup holes 11 in the same row are evenly distributed along the circumferential direction of the reaction cup holder 1;

[0030] A reaction cup 2, which is clamped in the reaction cup hole 11;

[0031] Code teeth 3 provided on the outer edge of the reaction cup holder 1, the code teeth 3 are arranged in one-to-one correspondence with the reaction cup rows, and the circumferential width of the code teeth 3 is smaller than the circumferential width of the reaction cup 2.

[0032] Please refer to Figure 1 , the reaction cup holder 1 is used to install the reaction cup 2 and install the reaction cup 2 on the installation table of the analytical instrument; considering the demand for reagents in the high-speed test of the analytical instrument, usually two or more rows of reaction cups 2 are provided on the reaction cup holder 1. In order to facilitate the photometric module of the analytical instrument to measure the reaction cup 2, the number of reaction cups 2 in each row of reaction cups 2 on the reaction cup holder 1 needs to be the same.

[0033] When the reaction cup holder 1 is provided with at least two rows of reaction cups 2, the reaction cups 2 are arranged in a radial and circumferential array along the reaction cup holder 1. Taking one end in the circumferential direction of the reaction cup holder 1 as the starting end, the rows of reaction cups 2 are numbered according to the distance. The reaction cups 2 with the same number should be located in the same orientation on the reaction cup holder 1, that is, the nth reaction cup in the first row of reaction cups 2 and the nth reaction cup in the second row are located in the same orientation (n is a positive integer) to form a reaction cup row.

[0034] The number of rows of reaction cups 2 on the reaction cup holder 1, the number of reaction cups 2 in each row of reaction cups 2, the radial distance between adjacent two rows of reaction cups 2, and the circumferential distance between adjacent two reaction cups 2 in the same row, etc., all need to be determined according to factors such as the structure and design throughput of the analytical instrument used in actual production to cooperate with the reaction cup assembly, and will not be elaborated here.

[0035] The reaction cup 2 is clamped in the reaction cup hole 11. To prevent the reaction cup 2 from falling out of the reaction cup hole 11, the reaction cup 2 and the reaction cup hole 11 can be set to have an interference fit at least in part of the contact length. During assembly, since the reaction cup 2 is made of a flexible material such as plastic, the reaction cup 2 can be pressed into the reaction cup hole 11 by pressing the outer wall of the reaction cup 2.

[0036] The size of the reaction cup 2, such as the length and capacity of the reaction cup 2, also needs to be determined according to the sample and reagent requirements of the analytical instrument in actual production, which will not be elaborated here.

[0037] The code teeth 3 are arranged on the outer edge of the reaction cup holder 1 relatively close to the photometric module. The code teeth 3 are used to trigger the photometric detection signal of the photometric module. Therefore, the code teeth 3 need to be arranged in one-to-one correspondence with the reaction cup rows so that the photometric module can perform photometry on each reaction cup 2.

[0038] In this embodiment, each reaction cup 2 is clamped in the reaction cup holder 1. When a certain reaction cup 2 is damaged, the reaction cup 2 can be taken out for replacement. Compared with replacing the entire reaction cup assembly, the replacement cost is effectively reduced.

[0039] On the basis of the above embodiment, in order to ensure the installation stability of the reaction cup 2, a limiting step surface can be provided in the reaction cup hole 11, and a limiting edge 21 protruding radially outward is provided at the top of the reaction cup 2. The limiting edge 21 is used to abut against the limiting step surface.

[0040] The reaction cup hole 11 can be set as a stepped hole so that the inner peripheral surface of the reaction cup hole 11 forms a limiting step surface; alternatively, a protruding limiting ring 12 can be provided at the top of the reaction cup holder 1. The inner diameter of the limiting ring 12 is larger than the diameter of the reaction cup hole 11, and the limiting ring 12 is used in cooperation with the top surface of the reaction cup holder 1 to form a limiting step surface.

[0041] Among them, using the limiting ring 12 to form a limiting step surface does not require the processing of a stepped hole. The limiting ring 12 can be integrally injection-molded with the reaction cup holder 1, which is more convenient for processing and manufacturing. And on the premise that the thickness of the reaction cup holder 1 is certain, the contact length between the reaction cup hole 11 and the reaction cup 2 is longer, and the clamping fit is more stable.

[0042] On the basis of the above embodiment, in order to stably install the reaction cup 2 in the reaction cup hole 11, a protruding mounting platform 13 can be provided at the bottom of the reaction cup holder 1, and the reaction cup hole 11 penetrates through the height direction of the mounting platform 13.

[0043] The shape of the mounting platform 13 is not limited. It can be set as a rectangular convex platform, a circular convex platform, etc. For the convenience of processing the reaction cup holder 1, the outer shape of the mounting platform 13 is usually set to be similar to the outer shape of the reaction cup 2. When the reaction cup 2 is a rectangular reaction cup, the mounting platform 13 is a rectangular convex platform;

[0044] The size of the mounting table 13 is determined according to the size of the reaction cup holder 1, the circumferential distance between two adjacent reaction cups 2 in the same row, and the radial distance between two adjacent reaction cups 2 in the same column in actual production, which will not be elaborated here.

[0045] In this embodiment, the setting of the mounting table 13 extends the length of the reaction cup hole 11, increases the contact length between the reaction cup hole 11 and the reaction cup 2, and thus improves the fitting stability and reliability between the two.

[0046] Preferably, in order to better fix the reaction cup 2, a limiting protrusion 22 protruding outward can be provided in the middle of the reaction cup 2. When the reaction cup 2 is clamped in the reaction cup hole 11, the limiting protrusion 22 abuts against the bottom surface of the mounting table 13, and the mounting table 13 is used to axially limit the reaction cup 2 to prevent the reaction cup 2 from easily falling out of the reaction cup hole 11.

[0047] The limiting protrusion 22 can be set as an annular protrusion surrounding the outer peripheral surface of the reaction cup 2, or can be set as two or more non-connected arc-shaped protrusions;

[0048] In order to facilitate the assembly of the reaction cup 2 and the reaction cup hole 11, the limiting protrusion 22 is usually set as an arc-shaped protrusion, and the limiting protrusion 22 is symmetrically arranged about the vertical symmetry plane of the reaction cup 2 to prevent the center of gravity of the reaction cup 2 from deviating relative to the axis of the reaction cup 2.

[0049] The radial distance of the arc-shaped protrusion 22 protruding from the outer peripheral surface of the reaction cup 22, the central angle of the arc-shaped protrusion 22 and other dimensions are determined according to factors such as the size and processing method of the reaction cup 22 in actual production, which will not be elaborated here.

[0050] On the basis of the above embodiment, in order to facilitate the connection between the code teeth 3 and the reaction cup holder 1, the code teeth 3 and the reaction cup holder 1 can be set as an integral structure. The code teeth 3 are connected to the outer edge of the reaction cup holder 1 through a connecting plate 14, and the connecting plate 14 is flush with the bottom surface of the reaction cup holder 1.

[0051] In this embodiment, the code teeth 3 and the reaction cup holder 1 are an integral structure, and the two can be integrally formed by injection molding. Compared with being separately processed and then connected by fasteners or bonding methods, the processing and assembly are convenient;

[0052] The connecting plate 14 is flush with the bottom surface of the reaction cup holder 1, which is beneficial to reducing the center of gravity of the reaction cup holder 1 and improving the stability of the reaction cup holder 1 itself.

[0053] The code teeth 3 are arranged in one-to-one correspondence with the reaction cup rows, and the alignment orientation of the two is not limited. Therefore, each code tooth 3 can be aligned with the side of the corresponding reaction cup row close to the starting end, or can be set to be aligned with the side of the corresponding reaction cup row far from the starting end;

[0054] However, for the convenience of the test process of the photometric module, the alignment of the code teeth 3 with the central axis of the corresponding reaction cup row is usually set. For example, please refer to Figure 4 , the code teeth 3 are rectangular code teeth, and the central axis of the rectangular code teeth is collinear with the central axis of the reaction cup row.

[0055] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0056] The reaction cup assembly for the analytical instrument provided by the present utility model has been introduced in detail above. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
