Description

Technical Field

[0001] The utility model belongs to the technical field of scattered light processing, and particularly relates to a scattered light processing disk for an analyzer. Background Technique

[0002] Biochemical, hemagglutination, and special protein analyzers are independent analytical instruments for three different detection and analysis methodologies. When the above three instruments are respectively performing detection and analysis, after a sample is added to a specific detection reagent, they respectively use a needle stirrer, a magnetic stirrer to stir, or tilt the reaction cup, and the liquid rapid impact method of the sampler to mix evenly, so that the reagent and the sample are fully mixed, so as to make the reaction uniform per unit time and the analysis result stable. When the sample to be detected and analyzed is a transparent sample, the light source of the analyzer can be detected and analyzed through the transmission analyzer; when the sample contains particulate matter, when the light source of the analyzer passes through the sample containing particles, the light source will be scattered, and the scattering angle is related to the size of the particulate matter.

[0003] The Chinese utility model patent with the publication number: CN213875401U discloses a scattered light processing disk for a multi-mode analyzer. Through its own adjustment, the scattered light processing disk can realize the change of the number and position of through holes, which is convenient to realize different scattered light detection modes and can meet the use requirements to a certain extent. However, this scattered light processing disk is used by setting a certain number of light-transmitting holes on the light-shielding disk. Due to the fixed position of the light-transmitting holes, the scattered light can only pass through the light-transmitting holes at a fixed angle. When it is necessary to transmit light from other angles, only the scattered light processing disk can be replaced, which leads to the limitation of the use of the scattered light processing disk.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a scattered light processing disk for an analyzer.

[0005] The information disclosed in this background section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art.

[0029] Among them, the outer blocking ring 1, the first blocking ring 2, the second blocking ring 3, the third blocking ring 4 and the inner blocking plate 5 are arranged in concentric circles, which facilitates the independent rotation of the first blocking ring 2, the second blocking ring 3 and the third blocking ring 4, so as to respectively adjust the first light-transmitting hole 202, the second light-transmitting hole 302 and / or the third light-transmitting hole 402 at any angle within the same circle, so that the scattered light can be transmitted from different angles, thereby meeting the different overall usage requirements of the scattered light processing disk and facilitating use.

[0030] In addition, a first groove 101 is provided in the outer shielding ring 1, and a first convex ring 201 is connected to the outer peripheral wall of the first shielding ring 2, and the first convex ring 201 is provided in the first groove 101. By providing the first convex ring 201 in the first groove 101, the first shielding ring 2 can be engaged with the outer shielding ring 1, and at the same time, the first shielding ring 2 can be relatively rotated with the outer shielding ring 1, so as to adjust the position of the first light-transmitting hole 202, so that the scattered light can be transmitted from the first light-transmitting hole 202 at different angles.

[0031] Specifically, the outer shielding ring 1 is provided with scale grooves 102 evenly distributed in a circumferential manner. The scale grooves 102 can play an indicating role, that is, they are used to indicate the rotation angle of the first shielding ring 2 or the second shielding ring 3 or the third shielding ring 4.

[0032] As Figures 1 to 4 shown, the first shielding ring 2 is provided with a plurality of first light-transmitting holes 202, the second shielding ring 3 is provided with a plurality of second light-transmitting holes 302 penetrating therethrough, and the third shielding ring 4 is provided with a plurality of third light-transmitting holes 402. The first light-transmitting holes 202, the second light-transmitting holes 302, and the third light-transmitting holes 402 can all play a role of transmitting light.

[0033] Among them, the inner wall of the first shielding ring 2 is provided with a second groove 203, and the outer peripheral wall of the second shielding ring 3 is connected with a second convex ring 301. The second convex ring 301 is arranged in the second groove 203. By arranging the second convex ring 301 in the second groove 203, the engagement between the first shielding ring 2 and the second shielding ring 3 can be achieved. At the same time, the first shielding ring 2 can also rotate relative to the second shielding ring 3, so as to adjust the position of the second light-transmitting holes 302 at any position within the same circumference, so that the scattered light can transmit through the second light-transmitting holes 302 at different angles.

[0034] As Figures 1 to 4 shown, the inner wall of the second shielding ring 3 is provided with a third groove 303, and the outer peripheral wall of the third shielding ring 4 is connected with a third convex ring 401. The third convex ring 401 is arranged in the third groove 303.

At the same time, the third shielding ring 4 can also rotate relative to the inner shielding plate 5.

[0036] As Figures 1 to 4 shown, handle posts 6 are installed on the first shielding ring 2, the second shielding ring 3, and the third shielding ring 4. The handle posts 6 facilitate the rotation of the first shielding ring 2, the second shielding ring 3, and / or the third shielding ring 4, and further can adjust the angles of the first light-transmitting holes 202, the second light-transmitting holes 302, and / or the third light-transmitting holes 402 at any position within the same circumference.

[0037] Among them, an indicating needle 601 is fixedly connected to the handle post 6, and the indicating needle 601 corresponds to the scale groove 102. Through the mutual cooperation of the indicating needle 601 and the scale groove 102, the rotation angle of the first shielding ring 2, the second shielding ring 3, and / or the third shielding ring 4 can be indicated.

The damping mechanism is used to increase the friction force, that is, under the action of an external force, the first shielding ring 2, the second shielding ring 3, and / or the third shielding ring 4 can be rotated. When the external force is stopped being applied, the first shielding ring 2, the second shielding ring 3, and / or the third shielding ring 4 are relatively stationary, and thus the required state can be maintained.

[0039] Preferably, the damping mechanism is a damping ring, and the plurality of damping rings are respectively attached to the first groove 101, the second groove 203, the third groove 303, and the fourth groove 403, and the damping rings are respectively in contact with the first convex ring 201, the second convex ring 301, the third convex ring 401, and the fourth convex ring 501. The damping rings are in a slightly interference fit with the first convex ring 201, the second convex ring 301, the third convex ring 401, and the fourth convex ring 501, and the damping rings are made of rubber or elastic material.

[0040] During specific use, the scattered light processing disk in the present application is installed between the sample and the detector, and then according to different requirements, as Figure 1 shown, the first shielding ring 2, the second shielding ring 3, and / or the third shielding ring 4 can be rotated, and then the positions of the first light-transmitting holes 202, the second light-transmitting holes 302, and the third light-transmitting holes 402 can be adjusted respectively, so that the scattered light can pass through the scattered light processing disk from different angles, and the change of the position of the light-transmitting through holes at any position within the same circumference can be realized, thereby meeting different use requirements.
