Description

Technical Field

[0001] This utility model relates to the field of microbial activity assay technology, and in particular to a bioactivity assay device. Background Technology

[0002] Biology is the science that studies the structure, function, occurrence, and development of organisms, plants, animals, and microorganisms; it is a part of the natural sciences.

[0003] Biological research includes the determination of microbial activity, which requires shaking to mix the materials thoroughly to improve the accuracy of the test. However, existing measuring devices cannot automatically mix the materials and all require manual operation, resulting in low efficiency of biological activity measurement.

[0004] Therefore, existing bioactivity assay devices suffer from the technical problem of not being able to automatically mix the samples. Summary of the Invention

[0005] The present invention provides a bioactivity assay device that solves the technical problem that existing bioactivity assay devices cannot automatically mix the samples.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A bioactivity assay device, comprising a base;

[0008] A slide table, which is slidably connected to the base;

[0009] A fixture for fixing the test dish, the fixture being disposed on the slide table;

[0010] and a drive assembly, which drives the fixture to rotate while simultaneously driving the slide to reciprocate relative to the base;

[0011] The drive assembly includes a motor fixed to the slide, the motor includes an output shaft, the fixture is fixed to the output shaft, and the output shaft drives the fixture to rotate;

[0012] A linkage mechanism is provided between the output shaft and the base to drive the slide table to slide relative to the base.

[0013] Preferably, the linkage mechanism includes a worm gear disposed on the output shaft, a worm wheel cooperating with the worm gear on the slide, the worm wheel being rotatably connected to the slide, the worm wheel being provided with an arc-shaped pusher that pushes the slide relative to the base to move in a first direction, the base being provided with a baffle that contacts the arc-shaped pusher, and an elastic element that pushes the slide relative to the base to move in a second direction between the base and the slide, wherein the first direction is opposite to the second direction.

[0014] Preferably, the slide is provided with a mounting bracket for mounting the worm gear, the worm gear is provided with a rotating shaft, and the mounting bracket is provided with a shaft hole that mates with the rotating shaft.

[0015] Preferably, the rotating shaft and the worm gear are an integral structure, and a rolling bearing is provided between the rotating shaft and the shaft hole.

[0016] Preferably, there are two mounting brackets, which are respectively disposed on both sides of the worm gear, and both mounting brackets are fixed to the base by screws.

[0017] Preferably, the arc-shaped pusher is mounted on the rotating shaft by a key connection, the arc-shaped pusher has a semi-circular cross-sectional shape, and the arc-shaped pusher is provided with a weight-reducing groove to reduce the weight of the arc-shaped pusher.

[0018] Preferably, the baffle is welded to the base, and a rib is provided between the baffle and the base. The rib is welded between the baffle and the base and is located on the side of the baffle away from the arc-shaped push plate.

[0019] Preferably, the output shaft and the worm gear are an integral structure, and the output shaft and the worm gear are coaxially arranged.

[0020] Preferably, the fixture is provided with a fixing groove, and the side wall of the fixing groove is provided with a positioning ridge for the positioning vessel.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] By incorporating a slide stage and a drive assembly, the motor of the drive assembly can rotate the fixture, while the test dish, fixed inside the fixture, rotates together with it, thus agitating the medium within the dish. Simultaneously, a linkage mechanism is incorporated, causing the slide stage to reciprocate relative to the base as the fixture rotates. This means the fixture exhibits both rotation and reciprocating linear motion, rapidly agitating the medium within the test dish, effectively improving both measurement accuracy and efficiency.

[0024] By setting up a linkage mechanism, only one motor is needed to realize the rotation and reciprocating linear motion of the fixture, which simplifies the structure of the bioactivity assay device and reduces the cost of using the bioactivity assay device. Attached Figure Description

[0037] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0038] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0039] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Reference Figures 1 to 6 As shown, a bioactivity assay device includes a base 1;

[0041] Slide 2, which is slidably connected to the base 1;

[0042] Fixture 21, the fixture 21 is used to fix the test dish 100, and the fixture 21 is disposed on the slide table 2;

[0043] And drive component 3, which drives the fixture 21 to rotate while driving the slide 2 to reciprocate relative to the base 1;

[0044] The drive assembly 3 includes a motor 31 fixed to the slide table 2. The motor 31 includes an output shaft. The fixture 21 is fixed to the output shaft, and the output shaft drives the fixture 21 to rotate.

[0045] A linkage mechanism is provided between the output shaft and the base 1 to drive the slide table 2 to slide relative to the base 1.

[0046] The method for determining bioactivity is a conventional method in this field, and the working principle of the measuring instrument is based on existing technology. The main improvement of this invention is to the fixture 21 of the measuring instrument, enabling the fixture 21 to quickly and evenly mix the medium within the container.

[0047] In some embodiments, the base 1 can be the housing structure of the measuring instrument.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the linkage mechanism includes a worm gear 32 disposed on the output shaft, a worm wheel 33 cooperating with the worm gear 32 on the slide table 2, the worm wheel 33 being rotatably connected to the slide table 2, the worm wheel 33 being provided with an arc-shaped pusher 34 that pushes the slide table 2 relative to the base 1 to move in a first direction, the base 1 being provided with a baffle 11 that contacts the arc-shaped pusher 34, and an elastic member 35 that pushes the slide table 2 relative to the base 1 to move in a second direction between the base 1 and the slide table 2, the first direction being opposite to the second direction.

[0049] Specifically, during the rotation of the output shaft of the motor 31, since the retainer 21 is directly fixed to the output shaft, the retainer 21 also rotates during the rotation of the output shaft, thus realizing the rotation action of the retainer 21.

[0050] Simultaneously, during the rotation of the output shaft, the worm gear 32 rotates together with the output shaft. The rotation of the worm gear 32 drives the worm wheel 33 to rotate, which in turn causes the worm wheel 33 to drive the arc-shaped push plate 34 to rotate. Since the arc-shaped push plate 34 is arc-shaped, when the arc-shaped push plate 34 contacts the baffle plate 11, the slide table 2 overcomes the elastic force of the elastic element 35 and moves in the first direction. As the arc-shaped push plate 34 continues to rotate, when the arc-shaped push plate 34 disengages from the baffle plate 11, the elastic element 35 pushes the slide table 2 to move in the second direction, thereby realizing the reciprocating motion of the slide table 2.

[0051] The arc-shaped pusher plate 34 has a boss structure.

[0052] Understandably, the speed of the slide 2 when it moves in the first direction and the speed of the slide 2 when it moves in the second direction may not be the same. However, even if the reciprocating speed of the slide 2 is not the same, it can still satisfy the mixing effect of the medium in the container.

[0053] Reference Figures 1 to 6 As shown, in some embodiments, the slide 2 is provided with a mounting bracket 36 for mounting the worm gear 33, the worm gear 33 is provided with a rotating shaft 331, and the mounting bracket 36 is provided with a shaft hole that mates with the rotating shaft 331.

[0054] In some embodiments, the rotating shaft 331 and the worm gear 33 are integral structures, and a rolling bearing is provided between the rotating shaft 331 and the shaft hole.

[0055] In some embodiments, there are two mounting brackets 36, which are respectively disposed on both sides of the worm gear 33, and both mounting brackets 36 are fixed to the base 1 by screws.

[0056] In some embodiments, the arc-shaped pusher 34 is mounted on the rotating shaft 331 by a key connection. The arc-shaped pusher 34 has a semi-circular cross-sectional shape and is provided with a weight-reducing groove to reduce its weight.

[0057] In some embodiments, the arc-shaped pusher 34 can be integrated with the rotating shaft 331.

[0058] In some embodiments, the baffle 11 is welded to the base 1, and a rib 12 is provided between the baffle 11 and the base 1. The rib 12 is welded between the baffle 11 and the base 1, and the rib 12 is located on the side of the baffle 11 away from the arc-shaped push plate 34.

[0059] In some embodiments, the output shaft and the worm gear 32 are an integral structure, and the output shaft and the worm gear 32 are coaxially arranged.

[0060] In some embodiments, the fixture 21 is provided with a fixing groove 211, and the side wall of the fixing groove 211 is provided with a positioning ridge 212 for positioning the vessel. The positioning ridge 212 is provided along the depth direction of the fixing groove 211, and the positioning ridge 212 is evenly distributed along the circumferential direction of the fixing groove 211.

[0061] In some embodiments, the slide 2 is provided with a guide rail 22, and the base 1 is provided with a guide groove 13 that cooperates with the guide rail 22. The cross-sectional shape of the guide rail 22 is a trapezoid that is wider at the top and narrower at the bottom.

[0062] In some embodiments, the elastic element 35 is a spring, which is disposed in the guide groove 13. One end of the spring is fixed to the side wall of the guide groove 13, and the other end of the spring is fixed to the end face of the guide rail 22.

[0063] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.
