Technical Field

[0001] This utility model relates to the field of chemical detection device technology, and in particular to a mixing and shaking device for a chemical detection instrument. Background Technology

[0002] The instruments used in chemical experiments are called chemical instruments. They are used to measure or react materials and are mainly divided into measuring instruments and reaction instruments. Instruments are combined in a specific way to form a device to achieve the experimental purpose. Chemical detectors can detect a variety of chemical substances and can assist in the detection and judgment of various types of substances, such as the environment and materials. Examples include the detection of vitamin B1 tablets, compound sulfamethoxazole tablets, enteric-coated aspirin tablets, and calcium salts in magnesium sulfate.

[0003] Currently, chemical detectors are used in the detection of modern chemical substances. In the process of using them, when testing some chemical substances, it is necessary to mix and shake the substances to be tested. Currently, the mixing of chemical substances is done manually by the staff, which leads to the problem of insufficient mixing of the substances to be tested.

[0004] Therefore, the existing chemical detection method of manually shaking the tested substance has technical problems such as uneven mixing of the tested substance and high labor intensity for workers. Utility Model Content

[0005] The present invention provides a mixing and shaking device for a chemical detector, which solves the technical problem in the prior art that the chemical detector uses manual shaking to mix the tested substances, resulting in uneven mixing of the tested substances and high labor intensity for the staff.

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

[0007] A mixing and shaking device for a chemical detector, comprising a frame;

[0008] A swing frame, the upper end of which is rotatably connected to the machine frame;

[0009] A drive mechanism drives the swing frame to reciprocate.

[0010] and a container, the container being inserted into the rack;

[0011] The driving mechanism includes a rotating shaft rotatably connected to the frame, the rotating shaft being provided with an eccentric wheel, a first driving plate and a second driving plate being provided at the lower end of the swing frame, the eccentric wheel being located between the first driving plate and the second driving plate, and the eccentric wheel driving the swing frame to reciprocate through the first driving plate and the second driving plate, the frame also being provided with a motor, and the rotating shaft being driven by the motor.

[0012] Preferably, the frame is provided with a mounting shaft, and the upper end of the swing frame is provided with a shaft hole that mates with the mounting shaft.

[0013] Preferably, the mounting shaft is welded to the frame, and a rolling bearing is provided between the mounting shaft and the shaft hole.

[0014] Preferably, the display stand is provided with a positioning frame for positioning the container, the positioning frame is provided with a positioning hole, and the container is inserted into the positioning hole.

[0015] Preferably, there are at least two positioning frames, each positioning frame positioning an independent container.

[0016] Preferably, an elastic positioning layer for positioning the container is bonded inside the positioning hole.

[0017] Preferably, the pendulum frame is provided with weight-reducing grooves to reduce the weight of the pendulum frame, and the weight-reducing grooves are evenly distributed on the pendulum frame.

[0018] Preferably, the first drive plate and the swing frame are an integral structure, the second drive plate and the swing frame are an integral structure, the swing frame is also provided with a connecting plate, and the lower ends of the first drive plate and the second drive plate are connected by the connecting plate.

[0019] Preferably, the eccentric wheel is mounted on the rotating shaft via a key connection, and the eccentric wheel has evenly distributed holes to reduce its weight, the holes penetrating the eccentric wheel.

[0020] Preferably, the motor is mounted on the frame via a mounting bracket, the motor is fixed to the mounting bracket with screws, and the mounting bracket is fixed to the frame with screws.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By setting up a pendulum frame and a drive mechanism, the container is inserted into the pendulum frame, and the drive mechanism drives the pendulum frame to swing back and forth. The movement trajectory of the container is similar to that of manual shaking. Using a drive mechanism to drive the pendulum frame allows the container to swing at a faster speed, so that the tested material in the container can be quickly and evenly mixed. At the same time, since the pendulum frame is driven by a drive mechanism, no manual operation is required, reducing the labor intensity of the staff.

[0023] By setting up an eccentric wheel, a first drive plate, and a second drive plate, the eccentric wheel alternately contacts the first drive plate and the second drive plate to realize the reciprocating swing of the pendulum frame. The drive mechanism has a simple structure and is easy to maintain, which reduces the operating cost of the mixing and shaking device of the chemical detector. Attached Figure Description

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Reference Figures 1 to 6 As shown, a chemical detector mixing and shaking device includes a frame 1;

[0039] The upper end of the swing frame 2 is rotatably connected to the frame 1;

[0040] Drive mechanism 3 drives the swing frame 2 to swing back and forth;

[0041] and container 21, which is inserted into the swing frame 2;

[0042] The drive mechanism 3 includes a rotating shaft 31 rotatably connected to the frame 1. The rotating shaft 31 is provided with an eccentric wheel 32. The lower end of the swing frame 2 is provided with a first drive plate 22 and a second drive plate 23. The eccentric wheel 32 is located between the first drive plate 22 and the second drive plate 23. The eccentric wheel 32 drives the swing frame 2 to swing back and forth through the first drive plate 22 and the second drive plate 23. The frame 1 is also provided with a motor 33. The rotating shaft 31 is driven by the motor 33.

[0043] Understandably, the lower end of the pendulum frame 2 is suspended in the air so that the pendulum frame 2 can swing within a certain angle range.

[0044] The container 21 is filled with the sample to be tested. The container 21 may or may not have a lid. Since the pendulum 2 uses a swinging motion to mix the sample in the container 21, the opening of the container 21 does not need to be moved to a downward position, and the sample in the container 21 will not fall out of the container 21.

[0045] In practice, when there are many test objects in container 21, container 21 can be fitted with a lid to prevent the test objects from falling out of container 21.

[0046] Reference Figures 1 to 2As shown, it can be understood that during the rotation of the eccentric wheel 32, the eccentric wheel 32 contacts the first drive plate 22. As the eccentric wheel 32 continues to rotate, it interferes with the first drive plate 22, thereby causing the pendulum frame 2 to swing at a certain angle along the first direction. As the eccentric wheel 32 continues to rotate, when it disengages from the first drive plate 22 and comes into contact with the second drive plate 23, it interferes with the second drive plate 23, thereby causing the pendulum frame 2 to swing at a certain angle along the second direction.

[0047] The eccentric wheel 32 rotates in a cycle, which drives the swing frame 2 to swing back and forth, realizing the function of the tested object in the mixing container 21.

[0048] In some embodiments, the frame 1 is provided with a mounting shaft 11, and the upper end of the swing frame 2 is provided with a shaft hole that mates with the mounting shaft 11.

[0049] Understandably, the mounting shaft 11 can also be mounted on the swing frame 2, with a shaft hole provided in the frame 1. The positions of the mounting shaft 11 and the shaft hole are not limited and can be reasonably determined according to needs.

[0050] In some embodiments, the mounting shaft 11 is welded to the frame 1, and a rolling bearing is provided between the mounting shaft 11 and the shaft hole. The outer ring of the rolling bearing is interference-fitted with the sidewall of the shaft hole, and the inner ring of the rolling bearing is interference-fitted with the mounting shaft 11.

[0051] Reference Figures 1 to 6 As shown, in some embodiments, the display stand 2 is provided with a positioning frame 24 for positioning the container 21, the positioning frame 24 is provided with a positioning hole 25, and the container 21 is inserted into the positioning hole 25.

[0052] In some embodiments, the positioning frame 24 may be an integral part of the swing frame 2. Alternatively, the positioning frame 24 may be fixed to the swing frame 2 via a detachable connection.

[0053] In some embodiments, there are at least two positioning frames 24, each positioning frame 24 positioning an individual container 21.

[0054] The number of positioning frames 24 is not limited and can be reasonably determined according to needs. The more positioning frames 24 there are, the more containers 21 can be set on the rack 2, and the more test objects can be mixed at one time by the rack 2.

[0055] Container 21 is typically made of glass so that staff can easily observe the object being tested inside. In some embodiments, an elastic positioning layer for positioning the container 21 is bonded inside the positioning hole 25.

[0056] The elastic positioning layer can be a rubber layer, or it can be a sponge layer.

[0057] Each positioning frame 24 may include multiple positioning rings, with an elastic positioning layer adhered to the inside of the positioning rings. Each container 21 may be positioned by at least two positioning rings.

[0058] The positioning ring can be integrated with the swing frame 2.

[0059] In practice, the lighter the weight of the pendulum frame 2, the less power the motor 33 needs. That is, the lighter the weight of the pendulum frame 2, the easier it is to be driven by the drive mechanism 3. In some embodiments, the pendulum frame 2 is provided with a weight-reducing groove 26 to reduce the weight of the pendulum frame 2. The weight-reducing groove 26 is evenly distributed on the pendulum frame 2.

[0060] Reference Figures 1 to 3 As shown, in some embodiments, the first drive plate 22 and the swing frame 2 are integral structures, the second drive plate 23 and the swing frame 2 are integral structures, and the swing frame 2 is also provided with a connecting plate 27, the lower ends of the first drive plate 22 and the second drive plate 23 are connected by the connecting plate 27.

[0061] The connecting plate 27 is an integral structure with the first drive plate 22 and the second drive plate 23. The connecting plate 27 connects the first drive plate 22 and the second drive plate 23 together. When the first drive plate 22 or the second drive plate interferes with the eccentric wheel 32, the connecting plate 27 can disperse the force exerted by the eccentric wheel 32 on the first drive plate 22 or the second drive plate 23, thereby making the pendulum frame 2 uniformly stressed and improving the stability of the pendulum frame 2.

[0062] The eccentric wheel 32 and the rotating shaft 31 should be stably connected so that the rotating shaft 31 can effectively drive the eccentric wheel 32 to rotate. In some embodiments, the eccentric wheel 32 is installed on the rotating shaft 31 by a key connection. The eccentric wheel 32 has evenly distributed holes to reduce the weight of the eccentric wheel 32, and the holes pass through the eccentric wheel 32.

[0063] The eccentric wheel 32 can be mounted on the shaft 31 via a spline.

[0064] In some embodiments, the motor 33 is mounted on the frame 1 via a mounting base 12, the motor 33 is fixed to the mounting base 12 by screws, and the mounting base 12 is fixed to the frame 1 by screws.

[0065] In some embodiments, the motor 33 can also drive the rotating shaft 31 through a gearbox to ensure that the rotating shaft 31 and the eccentric wheel 32 have a reasonable rotational speed. The motor 33 can also be a variable frequency motor 33 or the like to ensure that the rotating shaft 31 has a reasonable rotational speed.

[0066] Understandably, mixing the test material in container 21 by swinging the pendulum 2 results in higher mixing efficiency and more uniform mixing than mixing the test material in container 21 by rotating the container 21.

[0067] 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.

[0068] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0069] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
