Technical Field

[0001] The utility model relates to the technical field of luminescent immunoassay analyzers, and particularly to a luminescent immunoassay analyzer. Background Art

[0002] Luminescent immunoassay technology combines luminescence reaction with immunoassay to detect antigens or antibodies. It adopts micro-doubling technology, with good sensitivity and specificity, and a very wide detection range, capable of detecting from traditional proteins, hormones, enzymes to drugs.

[0003] When a luminescent immunoassay analyzer is in use, vibrations will be generated during the movement of its internal mechanical structure. The vibrations generated over a long time can only be dissipated by the slight movement and work of the internal components of the device. This is not only difficult to dissipate, but also can cause damage to the internal components of the device, and even reduce the overall accuracy. Long-term vibrations will also shorten the service life of the device. Therefore, a luminescent immunoassay analyzer is proposed to solve the above-mentioned problems. Content of the Utility Model

[0004] Based on the above description, the utility model provides a luminescent immunoassay analyzer to solve the problem that the existing luminescent immunoassay analyzer lacks a damping mechanism to dissipate vibrations.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 5 , a chemiluminescent immunoassay analyzer, comprising:

[0033] an analyzer main body 1; and

[0034] The metal frame 2 includes a main frame body 21, the main frame body 21 is disposed on the lower surface of the analyzer main body 1, and partition bars 22 are provided on the inner wall of the main frame body 21;

[0035] Based on the above, the metal frame 2 is made of a metal material that cannot be attracted by a magnet, such as aluminum. The main frame body 21 provides a space for the installation of the partition block 3, and the space is divided into upper and lower parts by the partition bars 22. The space in the lower part is provided for the shaking of the spherical permanent magnet 6.

[0036] Such as Figure 2 、 Figure 3 and Figure 6 As shown, the partition block 3 is disposed inside the metal frame 2. The partition block 3 includes a main block body 31. The main block body 31 is disposed inside the main frame body 21 and above the partition bars 22. An activity groove 32 and an opening groove 33 are sequentially provided on the upper surface of the main block body 31 from top to bottom, and a connection hole 34 is provided at one end of the main block body 31;

[0037] Based on the above, the partition block 3 functions to partition the space, separating the space in the metal frame 2 to facilitate the movement of the spherical permanent magnets 6 at different positions. The setting of the opening groove 33 enables the spherical permanent magnet 6 to be stuck into the inside of the opening groove 33 after moving upward, realizing the position fixation of the spherical permanent magnet 6.

[0038] Such as Figures 2 - 4 、 Figure 7 and Figure 8 As shown, the cover 7 is provided at one end of the metal frame 2 by screws. The cover 7 includes a cover plate 71. The cover plate 71 is provided at one end of the metal frame 2 by screws and extends into the metal frame 2 and contacts the partition block 3. A positioning blind hole 72 is provided on the outer surface of the cover plate 71;

[0039] The rotating rod 4 is arranged between the cover 7 and the metal frame 2 and penetrates through the partition block 3. The rotating rod 4 includes a main rod 41 which is arranged between the cover 7 and the metal frame 2. On the side of the main rod 41 away from the partition block 3, a prism 42 and a threaded column 43 are sequentially arranged.

[0040] The rotating sleeve 5 is arranged outside the rotating rod 4 through screws.

[0041] The spherical permanent magnet 6 is arranged on the lower surface of the rotating sleeve 5 through a rope, penetrates through the partition block 3 and extends into the metal frame 2.

[0042] Based on the above, the rotating rod 4 plays a role in fixing the rotating sleeve 5 and enables the rotating sleeve 5 to rotate together with the rotating rod 4. After the cover 7 and the metal frame 2 are connected to each other, they play a role in positioning the partition block 3, so that the partition block 3 is fixed inside the metal frame 2. The spherical permanent magnet 6 plays a role in providing a magnetic field. When the spherical permanent magnet 6 shakes, relative movement is generated with the metal frame 2, that is, cutting magnetic induction line movement. At this time, an induced magnetic field is generated inside the metal frame 2, and under the action of the induced magnetic field, the movement of the spherical permanent magnet 6 is hindered (i.e., the damping phenomenon), thereby achieving the effect of consuming the energy of vibration.

[0043] As Figures 2 - 4 and Figure 9 shown, a fixing cylinder 8 is arranged on the outer surface of the prism 42. A partition plate 9 is arranged on the outer surface of the threaded column 43 through a nut. A compression spring 10 is arranged between the fixing cylinder 8 and the partition plate 9. The fixing cylinder 8 includes a cylinder body 81. On the side of the cylinder body 81 close to the rotating sleeve 5, a prism hole 82 and a positioning column 83 are arranged. The prism hole 82 is adapted to the prism 42, and the positioning column 83 extends into the positioning blind hole 72.

[0044] Based on the above, under the action of the elastic force of the compression spring 10, the fixing cylinder 8 is closely attached to the cover 7, so that the positioning column 83 extends into the positioning blind hole 72. At this time, both the fixing cylinder 8 and the rotating rod 4 are in a fixed state. If it is necessary to rotate the fixing cylinder 8, the fixing cylinder 8 needs to be pulled, so that the positioning column 83 is withdrawn from the positioning blind hole 72 and then rotated. When the fixing cylinder 8 rotates, it drives the rotating rod 4 to rotate together. When the rotating rod 4 rotates, it drives the rotating sleeve 5 to rotate, thereby making the rope wind around the outer surface of the rotating sleeve 5 and making the spherical permanent magnet 6 snap into the opening groove 33.

[0045] In actual use of this embodiment, the analyzer main body 1 is powered on to work and generate vibrations. The vibrations are transmitted to the spherical permanent magnet 6 through the rope, causing the spherical permanent magnet 6 to shake under the action of the vibrations. The spherical permanent magnet 6 in the shaking state has relative movement with the metal frame 2, that is, a magnetic induction line cutting movement. At this time, an induced magnetic field is generated inside the metal frame 2, and the movement of the spherical permanent magnet 6 is hindered under the action of the induced magnetic field (damping phenomenon), thereby achieving the effect of consuming the energy of the vibrations and reducing the loss of internal components of the analyzer main body 1 caused by the vibrations by consuming the vibrations;

[0046] When the analyzer needs to be carried, the shaking spherical permanent magnet 6 is likely to collide with the metal frame 2. At this time, by pulling the fixed cylinder 8, the positioning column 83 can be withdrawn from the positioning blind hole 72 and then rotated. When the fixed cylinder 8 rotates, it drives the rotating rod 4 to rotate together. When the rotating rod 4 rotates, it drives the rotating sleeve 5 to rotate, so that the rope is wound around the outer surface of the rotating sleeve 5, and the spherical permanent magnet 6 is clamped into the inside of the opening groove 33. At this time, the spherical permanent magnet 6 is in a fixed position state, thus avoiding the situation that the spherical permanent magnet 6 shakes and impacts the metal frame 2 during the carrying process of the analyzer main body 1;

[0047] Compared with the traditional analyzer, this analyzer consumes the energy of the vibrations by setting a damping mechanism, reducing the loss of internal components of the analyzer caused by the vibrations and avoiding damage to the analyzer caused by the vibrations.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
