Description

Technical Field

[0001] The utility model relates to the field of sample analysis, in particular to a fixing frame and a sample analysis and extraction instrument. Background Art

[0002] Currently, instruments used for sample analysis integrate multiple functions, and correspondingly multiple working components are integrated and installed inside the instruments. However, the installation positions of the working components inside the rack are prone to deviation from the preset ideal positions, thereby affecting the use effect of the instrument. Utility Model Content

[0003] In view of this, the present application provides a fixing frame and a sample analysis and extraction instrument, wherein the fixing frame can be applied to the sample analysis and extraction instrument to fix the filter, and the limiting protrusion can guide the filter to the installation position in the fixing frame, thereby improving the operating performance of the sample analysis and extraction instrument, thereby solving the above-mentioned technical problems.

[0004] A first aspect of an embodiment of the present application provides a fixing bracket for fixing a filter, the fixing bracket comprising a base and a fixing portion, the surface of the base being provided with a limiting protrusion; the fixing portion is connected to the base, and the fixing portion and the base jointly limit a fixing cavity, the limiting protrusion being located in the fixing cavity, the fixing portion also being provided with a placement inlet, the filter being placed into the fixing cavity from the placement inlet, the cavity wall of the fixing cavity being used to push against the filter, and the limiting protrusion being used to push against the filter when the filter is placed into the fixing cavity.

[0005] Specifically, in the fixed cavity, a limiting protrusion protruding from the surface of the base is used to limit the filter. When the bottom of the filter abuts against the limiting protrusion, it proves that the filter has reached the specified installation position in the fixed cavity, and the filter can no longer continue to move along its assembly direction (refer to the width direction of the fixing frame embodiment in the figure). In this way, the filter stops at this position. The interaction between the filter and the limiting protrusion can prompt the operating object whether the filter is installed in place, and can effectively prevent the operating object from excessively moving the filter, causing the installation position of the filter in the fixed cavity to deviate from the standard installation position, so that the fixing frame can form the best fixing effect on the filter.

[0006] In some embodiments of the first aspect, the fixing part includes a first frame part, a second frame part and a connecting rod, the first frame part is provided with a first notch, the first frame part is arranged around the cavity periphery of the fixing cavity, the second frame part is provided with a second notch, the second frame part is arranged around the cavity periphery of the fixing cavity, one end of the connecting rod is connected to the first frame part, and the other end is connected to the second frame part; wherein, along the height direction of the fixing frame, the first frame part and the second frame part are arranged in sequence, and the second frame part is located between the first frame part and the base; the first notch is connected to the second notch to form the placement entrance, and the first frame part and the second frame part are used to support the filter. In this way, the fixing part has less consumables, which effectively reduces the production cost of the fixing part. At the same time, when the filter shakes in the fixing cavity, the degree of scratching between the filter and the fixing part can be reduced.

[0007] In some embodiments of the first aspect, the filter is connected to a movable end plate, which moves closer to or away from the filter; the second frame portion is also provided with an avoidance gap. When the filter is placed in the fixed cavity, the movable end plate corresponds to the avoidance gap, and the movable end plate moves into or out of the fixed cavity through the avoidance gap, so as to ensure that the filter is fixed while also ensuring the normal filtering operation of the filter.

[0008] In some embodiments of the first aspect, the base is also connected to a sliding platform, and along the height direction of the fixed frame, the sliding platform is located between the second frame portion and the base, the sliding platform is arranged parallel to the second frame portion, and the sliding platform is closer to the base than the second frame portion, and the movable end plate moves back and forth between the second frame portion and the sliding platform along the width direction of the fixed frame. In this way, along the height direction of the fixed frame, the sliding platform forms a certain constraint on the position of the movable end plate, and in the height direction of the fixed frame, the sliding platform does not interfere with the movement of the movable end plate, thereby ensuring the normal operation of the filter after it is installed on the fixed frame.

[0009] In some embodiments of the first aspect, a connecting platform is protruded from the outer periphery of the second frame portion, and the connecting platform extends toward a side away from the fixed cavity compared to the second frame portion and the outer periphery and the outer periphery of the first frame portion. In this way, a certain placement plane is formed on the fixed frame, and the filter or other components in the sample analysis and extraction instrument can be placed on the placement plane to participate in the operation process of the sample analysis and extraction instrument.

[0010] In some embodiments of the first aspect, the filter is connected to a connecting end plate, and an installation gap is formed between the connecting end plate and the surface of the filter; a positioning protrusion is convexly provided on the inner periphery of the fixing portion, and when the filter is located in the fixing cavity, the positioning protrusion is located in the installation gap. In this way, the provision of the positioning protrusion enhances the connection stability between the fixing frame and the filter, and also enhances the positioning and guiding effect of the filter during the installation process of the filter.

[0011] In some embodiments of the first aspect, the fixing portion is further connected to a strip, which is used to block the placement inlet and improve the connection stability between the filter and the fixing frame.

[0012] In some embodiments of the first aspect, the base is also connected to a positioning bracket, which is connected to a limiting protrusion. When the filter is located in the fixed cavity, the positioning bracket is fixedly connected to the side wall of the filter. In this way, the filter and the fixed frame are connected through the positioning bracket. The setting of the positioning bracket ensures the connection between the filter and the fixed frame, and also plays a certain restraining and guiding role on the installation position of the filter in the fixed cavity.

[0013] A second aspect of the embodiments of the present application provides a sample analysis and extraction instrument, comprising a filter and the fixing frame mentioned in the first aspect of the embodiments of the present application, wherein the filter is placed in a fixing cavity of the fixing frame.

[0014] In some embodiments of the second aspect, the sample analysis and extraction instrument also includes a frame and a connecting profile, which is used to reinforce the connection between the fixing frame and the frame, thereby maintaining the relative position relationship between the frame and the fixing frame to a certain extent, ensuring the structural stability of the frame after being connected to the fixing frame, and thus, improving the overall structural stability of the sample analysis and extraction instrument to a certain extent.

[0015] In some embodiments of the second aspect, the sample analysis and extraction instrument is an enterobacteria analysis and extraction instrument.

[0016] Among them, for the main beneficial effects of the second aspect, please refer to the beneficial effects of the first aspect, and no further details will be given here. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The following is a combination of the appended examples of the present application Figure 1-Figure 5, clearly and completely describe each technical solution in the embodiments of this application.

[0029] Please refer to Figures 1 to 3 The present application provides a sample analysis and extraction instrument 1000, comprising a filter 200 and a fixing frame 100. The filter 200 is placed in a fixing cavity 122 of the fixing frame 100 to be supported by the fixing frame 100 and participate in the operation of the sample analysis and extraction instrument 1000. The fixing frame 100 for fixing the filter 200 comprises a base 110 and a fixing portion 120. A limiting protrusion 111 is convexly provided on the surface of the base 110. The fixing portion 120 is connected to the base 110, and the fixing portion 120 and the base 110 jointly define a fixing cavity 122. The limiting protrusion 111 is located in the fixing cavity 122. The fixing portion 120 is further provided with a placement inlet 121. The filter 200 is placed into the fixing cavity 122 through the placement inlet 121. The cavity wall of the fixing cavity 122 is used to abut the filter 200. The limiting protrusion 111 is used to abut the filter 200 when the filter 200 is placed into the fixing cavity 122.

[0030] First of all, it should be noted that the filter 200 is not always located in the fixed cavity 122. The filter 200 can enter or leave the fixed cavity 122 through the placement inlet 121; the base 110 of the fixing frame 100 is connected to the fixing part 120 to form a fixed cavity 122 that supports and fixes the filter 200.

[0031] Specifically, in the fixing cavity 122, the limiting protrusion 111 protruding from the surface of the base 110 is used to limit the filter 200. When the bottom of the filter 200 abuts against the limiting protrusion 111, it proves that the filter 200 has reached the specified installation position in the fixing cavity 122, and the filter 200 can no longer continue to move along its assembly direction (refer to the width direction B of the embodiment of the fixing frame 100 in the figure). In this way, the filter 200 stops at this position. The interaction between the filter 200 and the limiting protrusion 111 can prompt the operating object whether the filter 200 is installed in place, and can effectively prevent the operating object from excessively moving the filter 200, causing the installation position of the filter 200 in the fixing cavity 122 to deviate from the standard installation position, so that the fixing frame 100 can form the best fixing effect on the filter 200.

[0032] It should be understood that when the filter 200 is installed in the standard installation position, the filter 200 will not cause the fixing frame 100 to vibrate excessively due to operational vibrations. Thus, the fixing frame 100 will not excessively collide with the frame 300. Therefore, no abnormal noise will occur during the operation of the sample analysis and extraction instrument 1000, allowing the sample analysis and extraction instrument 1000 to operate normally.

[0033] Please refer to Figure 2In some embodiments, the sample analysis and extraction instrument 1000 further includes a frame 300 and a connecting profile 400. The connecting profile 400 is used to reinforce the connection between the fixing frame 100 and the frame 300. That is, the connecting profile 400 can further connect the frame 300 and the fixing frame 100 by itself to strengthen the interaction between the frame 300 and the fixing frame 100. The connecting profile 400 can also maintain the relative position relationship between the frame 300 and the fixing frame 100 to a certain extent because it has a certain anti-deformation ability and increases the connection area between the frame 300 and the fixing frame 100, thereby ensuring the structural stability of the frame 300 after being connected to the fixing frame 100, and thus improving the overall structural stability of the sample analysis and extraction instrument 1000 to a certain extent.

[0034] It should be further explained that, since the frame 300 is connected to multiple operating structures, once the relative position between the frame 300 and the fixed frame 100 changes, the fixed frame 100 and the other operating structures may interfere with each other, or affect the correspondence between the filter 200 and the other operating structures, thereby affecting the normal operation of the sample analysis and extraction instrument 1000 as a whole. Therefore, in the above embodiment, by adding the connecting profile 400, the overall stiffness of the frame 300 and the fixed frame 100 after connection is increased, thereby effectively solving the above situation.

[0035] Please refer to Figure 5 In some embodiments, the fixing portion 120 includes a first frame portion 123, a second frame portion 126 and a connecting rod 127, the first frame portion 123 is provided with a first notch 123a, the first frame portion 123 is arranged around the cavity periphery of the fixing cavity 122, the second frame portion 126 is provided with a second notch 126a, the second frame portion 126 is arranged around the cavity periphery of the fixing cavity 122, one end of the connecting rod 127 is connected to the first frame portion 123, and the other end is connected to the second frame portion 126; wherein, along the height direction A of the fixing frame 100, the first frame portion 123 and the second frame portion 126 are arranged in sequence, and the second frame portion 126 is located between the first frame portion 123 and the base 110; the first notch 123a is connected to the second notch 126a to form the placement entrance 121, and the first frame portion 123 and the second frame portion 126 are used to support the filter 200.

[0036] Specifically, the first frame portion 123, the second frame portion 126 and the connecting support rod 127 are connected to form the fixing portion 120 and limit the fixing cavity 122. In this way, the fixing portion 120 consumes less material, which effectively reduces the production cost of the fixing portion 120; in addition, the first frame portion 123 and the second frame portion 126 are arranged around the outer periphery of the filter 200. When the filter 200 is connected to the fixing frame 100, the first frame portion 123 and the second frame portion 126 form a limiting effect on the filter 200 at its different positions to prevent the filter 200 from excessively shaking in the fixing cavity 122. At the same time, the solid cavity wall of the fixing cavity 122 is formed on the inner side wall of the first frame portion 123 and the second frame portion 126. In this way, the contact area between the fixing portion 120 and the filter 200 is effectively reduced. When the filter 200 shakes in the fixing cavity 122, the degree of scratching between the filter 200 and the fixing portion 120 can be reduced.

[0037] Please refer to Figure 3 and Figure 5 In some embodiments, the filter 200 is connected to a movable end plate 210, and the movable end plate 210 moves closer to or away from the filter 200; the second frame portion 126 is also provided with an avoidance notch 126b. When the filter 200 is placed in the fixed cavity 122, the movable end plate 210 corresponds to the avoidance notch 126b, and the movable end plate 210 moves into or out of the fixed cavity 122 through the avoidance notch 126b.

[0038] Among them, the filter 200 improves the efficiency and accuracy of the filtering operation of the filter 200 itself by adding a movable end plate 210. Accordingly, in order not to hinder the movement of the movable end plate 210, the fixing frame 100 is correspondingly provided with an avoidance gap 126b on the second frame portion 126, so as to ensure that the filter 200 is fixed while also ensuring the normal filtering operation of the filter 200.

[0039] Please continue to refer to Figure 3 and Figure 5In some embodiments, the base 110 is further connected to a sliding platform 130. Along the height direction A of the fixing frame 100, the sliding platform 130 is located between the second frame portion 126 and the base 110. The sliding platform 130 is arranged parallel to the second frame portion 126, and the sliding platform 130 is closer to the base 110 than the second frame portion 126. The movable end plate 210 reciprocates between the second frame portion 126 and the sliding platform 130 along the length direction C of the fixing frame 100. In this way, along the height direction A of the fixing frame 100, the sliding platform 130 forms a certain constraint on the position of the movable end plate 210, further guiding and restricting the installation position of the filter 200 when installing the filter 200, and in the height direction A of the fixing frame 100, the sliding platform 130 does not interfere with the movement of the movable end plate 210, thereby ensuring the normal operation of the filter 200 after being installed on the fixing frame 100.

[0040] Please refer to Figure 5 In some embodiments, a connecting platform 126 c is protruded from the outer periphery of the second frame portion 126 , and the connecting platform 126 c extends toward a side away from the fixing cavity 122 compared to the outer periphery of the second frame portion 126 and the outer periphery of the first frame portion 123 . In this way, a certain placement plane is formed on the fixing frame 100 , and the filter 200 or other components in the sample analysis and extraction instrument 1000 can be placed on the placement plane to participate in the operation process of the sample analysis and extraction instrument 1000 .

[0041] Please refer to Figure 3 and Figure 4 In some embodiments, the filter 200 is connected to a connecting end plate 220, and an installation gap is formed between the connecting end plate 220 and the surface of the filter 200; a positioning protrusion 124 is convexly provided on the inner periphery of the fixing portion 120, and when the filter 200 is located in the fixing cavity 122, the positioning protrusion 124 is located in the installation gap. In this way, the provision of the positioning protrusion 124 enhances the limiting effect and restraint effect between the fixing frame 100 and the filter 200, and strengthens the connection stability between the fixing frame 100 and the filter 200; in addition, when the fixing frame 100 is connected to the filter 200, the operating object can complete the position correspondence between the fixing frame 100 and the filter 200 by aligning its positioning protrusion 124 with the installation gap, that is, the provision of the positioning protrusion 124 enhances the positioning and guiding effect of the filter 200 during the installation process of the filter 200.

[0042] Please refer to Figure 5In some embodiments, the fixing portion 120 is further connected to a strip 125, which is used to block the placement inlet 121 so that after the filter 200 is installed to the specified position, the fixing cavity 122 forms a new fixed cavity wall again, thereby constraining the filter 200 along the radial direction of the fixing cavity 122, preventing the filter 200 from detaching from the fixing cavity 122 along the placement inlet 121 during operation, thereby improving the connection stability between the filter 200 and the fixing frame 100.

[0043] In some embodiments, the base 110 is also connected to a positioning bracket 140, which is connected to the limiting protrusion 111. When the filter 200 is located in the fixed cavity 122, the positioning bracket 140 is fixedly connected to the side wall of the filter 200. In this way, the filter 200 is connected to the fixing frame 100 through the positioning bracket 140. The setting of the positioning bracket 140 ensures the connection between the filter 200 and the fixing frame 100, and also plays a certain restraining and guiding role on the installation position of the filter 200 in the fixed cavity 122.

[0044] Among them, the positioning bracket 140 and the limiting protrusion 111 can be set integrally, the limiting protrusion 111 is used to limit and constrain the installation position of the bottom of the filter 200 in the fixed cavity 122, and the positioning bracket 140 is used to provide a connection surface for the filter 200, so that the filter 200 can be fixedly connected to the fixing frame 100 by connecting the positioning bracket 140; it should also be noted that the positioning bracket 140 can be provided with a certain accommodating space to accommodate the pump body and other related components required for the operation of the filter tank, thereby reducing the space occupied by the filter element, the fixing frame 100 and the related components after assembly to a certain extent, and realizing the miniaturization of the overall product of the sample analysis and extraction instrument 1000.

[0045] In some embodiments, the sample analysis and extraction instrument 1000 is an intestinal bacteria analysis and extraction instrument. In other embodiments, the sample analysis and extraction instrument 1000 can also be other instruments such as a particle sieving instrument and a purifying instrument.

[0046] It should be noted that the above-mentioned positioning frame is not limited to the application in the sample analysis and extraction instrument 1000 and the filter 200, but can also be applied to other sample analysis components or products that need to be fixed, such as samplers, stirrers, purifiers, etc.

[0047] It should be noted that for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that this application is not limited by the order of the actions described, because according to this application, certain steps can be performed in other orders or simultaneously.
