Description

Technical Field

[0001] This invention relates to an elastic limiting component, an oscillator, and a medical device. Background Technology

[0002] In related technologies, a clamping device is often used to hold and fix a container, and then a vibrator is used to drive the container on the clamping device to reciprocate to mix the materials.

[0003] For example, in a microplate oscillator, a microplate is placed on an oscillation tray. The microplate has a unit cavity for containing liquid, and the oscillation tray drives the microplate to oscillate. To prevent the microplate from being thrown out, limit blocks are usually placed at the four corners of the oscillation tray. These limit blocks contact the sidewalls of the microplate to restrict its movement relative to the oscillation tray.

[0004] However, when there is a gap between the microplate and the limiting block, the microplate will hit the limiting block back and forth during the operation of the microplate oscillator, generating a lot of noise. If the oscillation speed is too fast, the microplate will be thrown out, causing liquid to spill. When the distance between the limiting blocks is too small, it will be difficult to put the microplate into the oscillation tray. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide an elastic limiting component capable of adjusting the elastic deformation of an elastic plate so that a limiting block can remain against a container; a second objective is to provide an oscillator employing the above elastic limiting component; and a third objective is to provide a medical device employing the above oscillator.

[0006] According to a first aspect of the present invention, an elastic limiting component includes: a limiting block having an elastic plate disposed thereon, the elastic plate being capable of elastic deformation relative to the limiting block; and an adjusting component disposed on the limiting block for driving the elastic plate to undergo elastic deformation so that the elastic plate abuts against a container.

[0007] An elastic limiting component according to a first aspect embodiment of the present invention has at least the following beneficial effects:

[0008] The above-mentioned elastic limiting component uses an adjusting component to adjust the deformation of the elastic plate relative to the limiting block. During the adjustment process, the distance between the elastic plate and the container gradually decreases until the elastic plate and the container come into contact and fit tightly. By adjusting the deformation of the elastic plate against the container, the clamping force of the elastic plate on the container can be adjusted, which is to adjust the interference between the elastic plate and the container. When the container is in oscillating operation, the elastic plate always remains against the container to keep the container relatively stable, avoid rigid collision between the container and the limiting block, and prevent the container from falling off the limiting block or spilling materials. Moreover, this elastic limiting component is easy to pick up and put down the container and can also be used to limit the movement of containers of various sizes and specifications.

[0009] In some embodiments of the present invention, the adjusting component includes a pusher movably disposed on the limiting block, the pusher being able to directly or indirectly abut against the elastic plate, and the pusher being able to perform a feeding motion relative to the limiting block to push the elastic plate to elastically deform.

[0010] In some embodiments of the present invention, the pushing member is a bolt threaded to the limiting block, and the adjusting assembly further includes an elastic connector, the two ends of which abut against or connect to the end of the bolt and the elastic plate, respectively.

[0011] In some embodiments of the present invention, the limiting block includes an inner side plate and an outer side plate spaced apart. A connecting plate is provided between the upper end of the inner side plate and the upper end of the outer side plate. At least a portion of the inner side plate constitutes the elastic plate. The inner side plate, the outer side plate, and the connecting plate together define a downward-opening mounting groove. The end of the bolt and the elastic connector are both located within the mounting groove.

[0012] In some embodiments of the present invention, the elastic connector includes an insert portion and a bent piece connected to the insert portion. The limiting block is provided with a limiting slot located on one side of the inner side plate. The insert portion is inserted into the limiting slot. The bent piece elastically abuts against the end of the bolt so that the insert portion elastically abuts against the inner side plate.

[0013] In some embodiments of the present invention, the bolt is threaded to the connecting plate in a vertical direction, and the lower end of the bolt pushes against one end of the elastic connector so that the other end of the elastic connector pushes the elastic plate to deform.

[0014] In some embodiments of the present invention, the inner side plate includes a first plate and a second plate that are perpendicular to each other, and the outer side plate includes a third plate and a fourth plate that are perpendicular to each other. The first plate is parallel to the third plate, and the second plate is parallel to the fourth plate. An adjustment component is disposed between the first plate and the third plate, and between the second plate and the fourth plate.

[0015] An oscillator according to a second aspect of the present invention includes: an oscillating tray, wherein the oscillating tray is provided with the elastic limiting component described in any of the above technical solutions.

[0016] The oscillator according to the second aspect of the present invention has at least the following beneficial effects:

[0017] The oscillator using the above-mentioned elastic limiting component can adjust the clamping force applied to the container, which can stably clamp the container and prevent the container from colliding with the limiting component, and also makes it easy to install and remove the container from the oscillating tray for convenient use.

[0018] In some embodiments of the present invention, the oscillating tray is provided with four limiting members, which are distributed at the four corners of a rectangle and form an installation area for placing liquid containers. Each limiting member has a vertical segment and a horizontal segment that are orthogonal to each other, and the vertical segment and the horizontal segment are provided with the elastic limiting component.

[0019] In some embodiments of the present invention, the oscillation tray is rectangular, and a limiting member is provided at both ends of the left edge, right edge, front edge and rear edge of the oscillation tray, and one of the two opposing limiting members includes the elastic limiting component.

[0020] A medical device according to a third aspect of the present invention includes: the oscillator described in any of the above technical solutions.

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be understood that the orientation descriptions, such as the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer", indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0039] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] See Figures 1 to 4 The present invention provides an elastic limiting component, comprising: a limiting block 100, wherein an elastic plate is provided on the limiting block 100, the elastic plate being capable of elastic deformation relative to the limiting block 100; and an adjusting component 200 disposed on the limiting block 100 for driving the elastic plate to produce elastic deformation so that the elastic plate abuts against the clamped container.

[0042] The above elastic limiting assembly uses adjusting component 200 to adjust the amount of deformation of the elastic plate along the limiting block 100 outwards. See [link / reference]. Figure 6 and Figure 7 During the adjustment process, the distance between the elastic plate and the container 10 gradually decreases until the elastic plate and the container 10 come into contact and fit tightly. By adjusting the amount of deformation when the elastic plate abuts against the container 10, the clamping force of the elastic plate on the container 10 can be adjusted, which is to say, the interference fit between the elastic plate and the container 10 is adjusted. When the container 10 is in oscillating operation, the elastic plate always stays against the container 10 to keep the container 10 relatively stable, avoids rigid collision between the container 10 and the limiting block 100, and prevents the container 10 from falling off the limiting block 100 or spilling materials. Moreover, this elastic limiting component is convenient for picking up and putting down the container 10 and can also be used to limit the movement of containers 10 of various sizes and specifications.

[0043] See Figure 2 , Figure 3 and Figure 4In some embodiments of the present invention, the adjusting assembly 200 includes a pusher 210 movably disposed on the limiting block 100. The pusher 210 can directly or indirectly abut against the elastic plate, and the pusher 210 can perform a feeding movement relative to the limiting block 100 to push the elastic plate to deform elastically. It is understood that the displacement of the pusher 210 relative to the limiting block 100 is positively correlated with the amount of elastic deformation of the elastic plate. The feeding movement of the pusher 210 can adjust the interference between the elastic plate and the container 10, thereby providing different magnitudes of clamping force to the container 10.

[0044] See Figure 3 and Figure 4 In some embodiments of the present invention, the pusher 210 is a bolt threaded to the limiting block 100, and the adjusting assembly 200 further includes an elastic connector 220, the two ends of which abut or connect with the end of the bolt and the elastic plate, respectively. It is understood that the pusher 210 indirectly abuts against the elastic plate through the elastic connector 220. The limiting block 100 has a space for the elastic plate and the elastic connector 220 to deform together. When the container 10 presses against the elastic plate, the elastic plate and the elastic connector 220 deform elastically together, extending the travel of the elastic plate and preventing the container 10 from easily colliding rigidly with the pusher 210. This provides shock absorption and buffering when the container 10 vibrates. Furthermore, since the pusher 210 is a bolt threaded to the limiting block 100, the deformation of the elastic plate can be finely adjusted by turning the bolt, resulting in high adjustment precision. Of course, in other embodiments, the pusher 210 can also be replaced by the following: the pusher 210 includes a rod that passes through the limiting block 100. The rod is provided with a plurality of stop slots at intervals along its length. The limiting block 100 is provided with a retaining spring that can move in and out of any stop slot. When the rod moves a certain distance along its length on the limiting block 100, the pusher 210 can be fed by the retaining spring cooperating with the corresponding stop slot, and the interference between the elastic plate and the container 10 can be adjusted at the same time.

[0045] See Figure 3 and Figure 4In some embodiments of the present invention, the limiting block 100 includes an inner side plate 110 and an outer side plate 120 spaced apart. A connecting plate 130 is provided between the upper end of the inner side plate 110 and the upper end of the outer side plate 120. At least a portion of the inner side plate 110 constitutes an elastic plate. The inner side plate 110, the outer side plate 120, and the connecting plate 130 together define a downward-opening mounting groove 140. The end of the bolt and the elastic connector 220 are both located within the mounting groove 140. In this embodiment, the inner side plate 110, the outer side plate 120, and the connecting plate 130 are an integral structure formed by injection molding, which helps to simplify the production and processing procedures. The fact that at least a portion of the inner side plate 110 directly constitutes an elastic plate can both simplify the production process and reduce material costs. The elastic connector 220 is placed inside the mounting groove 140 along the opening of the mounting groove 140. The end of the bolt extends into the mounting groove 140 and abuts against the elastic connector 220, which avoids the elastic connector 220 being placed outside the limiting block 100 and thus prevents the elastic connector 220 from being accidentally touched. At the same time, it improves the structural compactness of the elastic limiting assembly.

[0046] See Figures 2 to 4 In some embodiments of the present invention, the elastic connector 220 includes an insert portion 221 and a bent piece 222 connected to the insert portion 221. A limiting slot 150 is provided within the limiting block 100 on one side of the inner side plate 110. The insert portion 221 is inserted into the limiting slot 150, and the bent piece 222 elastically abuts against the end of the bolt, causing the insert portion 221 to elastically abut against the inner side plate 110. In this embodiment, the connection between the insert portion 221 and the bent piece 222 forms an approximately 90° angle. The cross-section of the entire assembly of the insert portion 221 and the bent piece 222 is approximately "L"-shaped. When the bolt is tightened to push the bent piece 222 against the bolt end, both the angle and the insert portion 221 push the inner side plate 110 outwards, thereby adjusting the deformation of the elastic plate, which also adjusts the interference fit between the elastic plate and the container 10.

[0047] See Figure 1 and Figure 2 In some embodiments of the present invention, a bolt is threaded vertically onto a connecting plate 130, and the lower end of the bolt pushes against one end of an elastic connector 220 to cause the other end of the elastic connector 220 to push the elastic plate outward. This method of loosening the bolt by holding a screwdriver above the connecting plate 130 is very convenient.

[0048] In some embodiments of the present invention, the inner plate 110 includes a first plate 111 and a second plate 112 perpendicular to each other, and the outer plate 120 includes a third plate 121 and a fourth plate 122 perpendicular to each other. The first plate 111 and the third plate 121 are parallel, and the second plate 112 and the fourth plate 122 are parallel. Adjustment components 200 are disposed between the first plate 111 and the third plate 121, and between the second plate 112 and the fourth plate 122. It should be noted that the first plate 111 and the second plate 112 respectively constitute two elastic plates, and the two adjustment components 200 are respectively used to adjust the amount of outward deformation of the first plate 111 and the second plate 112, thereby adjusting the clamping force of the limiting block 100 on the container 10 in two mutually perpendicular directions to ensure that the container 10 can be stably clamped.

[0049] See Figure 5 or Figure 8 The present invention also discloses an oscillator, comprising: an oscillating tray 300, wherein the oscillating tray 300 is provided with an elastic limiting component of any of the above-mentioned technical solutions. The oscillator using the above-mentioned elastic limiting component can adjust the clamping force acting on the container 10, which can stably clamp the container 10, avoid collision between the container 10 and the limiting component 400, and facilitate the installation and removal of the container 10 from the oscillating tray 300, making it convenient to use.

[0050] See Figure 5 , Figure 6 and Figure 7 In some embodiments of the present invention, the oscillating tray 300 is provided with four limiting members 400. The four limiting members 400 are distributed at the four corners of a rectangle and form an installation area for placing the liquid container 10. Each limiting member 400 has a vertical segment and a horizontal segment that are orthogonal to each other, and both the vertical segment and the horizontal segment are provided with elastic limiting components. See also Figure 5 The horizontal section extends in the left-right direction, and the vertical section extends in the front-back direction. It should be noted that the vertical section has the aforementioned second plate 112, and the horizontal section has the aforementioned first plate 111. That is, each of the four limiting members 400 is equipped with two elastic limiting components to adjust the elastic abutment force acting on the container 10 on the oscillating tray 300 along the length and width directions of the oscillating tray 300, thereby adjusting the tightness of clamping the container 10 to a suitable range so that the container 10 can be directly inserted into the installation area enclosed by the four limiting members 400 when installing and fixing the container 10 next time.

[0051] See Figure 8 In some embodiments of the present invention, the oscillation tray 300 is rectangular, and a limiting member 400 is provided at both ends of the left edge, right edge, front edge and rear edge of the oscillation tray 300. One of the two opposing limiting members 400 includes an elastic limiting component.

[0052] Limiting members 400 are provided at the front and rear ends of the left edge, the front and rear ends of the right edge, the left and right ends of the front edge, and the left and right ends of the rear edge of the oscillating tray 300. The limiting member 400 located at the front end of the left edge or the front end of the right edge of the oscillating tray 300 includes an elastic limiting component. The limiting member 400 located at the rear end of the left edge or the rear end of the right edge of the oscillating tray 300 includes an elastic limiting component. The limiting member 400 located at the left end of the front edge or the left end of the rear edge of the oscillating tray 300 includes an elastic limiting component. The limiting member 400 located at the right end of the front edge or the right end of the rear edge of the oscillating tray 300 includes an elastic limiting component.

[0053] The oscillator with the above structure only needs to be equipped with four elastic limiting components to adjust the elastic resistance force acting on the container 10 in the length and width directions of the oscillation tray 300, thus saving costs.

[0054] The present invention also discloses a medical device comprising: an oscillator according to any of the above-described technical solutions. This medical device can be a fully automated blood typing analyzer, or other medical devices comprising an oscillator according to any of the above-described technical solutions.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
