Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of microorganism culture, and relates to a split type loader. BACKGROUND

[0002] Microorganism sample culture is an important work in medical health, inspection and quarantine, disease control and food safety. At present, automatic inoculation loaders are generally used in microorganism inoculation, culture, separation and detection. For example, an automatic inoculation loader is disclosed in Chinese patent [authorized publication number CN212833771U], which comprises a box body and a box cover rotatably connected to the box body. A rotating shaft type clamping piece is installed on one of the box body and the box cover, and a clamping block is arranged on the other one. The rotating shaft type clamping piece can be matched with the clamping block to lock the box body and the box cover.

[0003] The above-mentioned loader needs to assemble the box body and the box cover together during production, and the structure design is complex. The rotating shaft type clamping piece needs to be installed on one of the box body and the box cover, and the assembly is complex and the assembly efficiency is low. The mechanical opening device needs to be operated when the cover is opened, and the use cost is high. The box cover is turned outward around the rotating shaft during inoculation, and the occupied space is large. The information marking bar code is usually attached to the box cover, and the opaque information marking bar code has an influence on the observation of the growth state of the culture medium. UTILITY MODEL CONTENT

[0004] The utility model aims at the above-mentioned problems existing in the prior art, and provides a split type loader with simple structure design.

[0005] The purpose of the utility model can be realized through the following technical schemes.

[0006] The split type loader comprises a box body provided with a storage cavity and a box cover provided separately from the box body. The box body is provided with a first annular stopper around the storage cavity. The box cover is provided with a second annular stopper. When the box cover is closed on the box body, the second annular stopper is located outside the first annular stopper and gap fits between the second annular stopper and the first annular stopper. A support structure is arranged between the box body and the box cover to gap fit the upper end surface of the first annular stopper with the inner top surface of the box cover when the box cover is closed.

[0007] The storage cavity is used for loading culture medium, and microorganisms are inoculated on the culture medium during use. The structure design is reasonable, the split type setting is adopted, the assembly process is reduced, the box cover is sucked away through negative pressure during inoculation, the occupied space of the box body is reduced, and the microorganisms inoculated on the culture medium can exchange air through the gap after the box cover is closed on the box body.

[0008] The first annular stopper and the second annular stopper are gap fitted, which can limit the box cover in the horizontal direction and prevent the box cover from falling off during movement.

[0009] In the aforementioned split-type loader, the support structure includes a plurality of protrusions on the upper surface of the box body. The plurality of protrusions are arranged in a circular array along the first annular flange. When the box cover is closed, the lower end of the second annular flange abuts against the protrusions.

[0010] The distance from the upper surface of the protrusion to the upper surface of the first annular step is less than the distance from the lower end face of the second annular flange to the inner top surface of the lid. The protrusion supports the lid, and when the lid is closed, the upper end face of the first annular flange is in clearance fit with the inner top surface of the lid.

[0011] To ensure that the second annular retaining edge always presses against the protrusion, the protrusion is designed as a strip and extends radially along the first annular retaining edge.

[0012] In the aforementioned split-type loader, the support structure includes several protrusions on the inner top surface of the lid, and the several protrusions are distributed in a circular array along the second annular flange. When the lid is closed, the upper end of the first annular flange abuts against the protrusions.

[0013] The lid is supported by a protrusion. When the upper surface of the first annular retaining edge abuts against the protrusion, the upper surface of the first annular retaining edge is in clearance fit with the inner top surface of the lid. To ensure that the first annular retaining edge always abuts against the protrusion, the protrusion is set in the shape of a strip and extends radially along the second annular retaining edge.

[0014] In the aforementioned split-type loader, the outer surface of the first annular flange is a guide surface that slopes outward from top to bottom. Because of the guide surface, the outer diameter of the upper end of the first annular flange is smaller, and the outer diameter increases towards the bottom, making it easier to place the lid onto the box body.

[0015] In the aforementioned split-type loader, the upper surface of the box has an adhesive area for attaching information label barcodes, the adhesive area being located to the side of the first annular flange.

[0016] Affixing the information label barcode to the designated area effectively ensures the accuracy of information about the microorganisms and the culture medium. Furthermore, since the area is located to the side of the first annular barrier, the information label barcode will not obstruct observation of the culture medium's growth status.

[0017] In the aforementioned split-type loader, the outer periphery of the box body is provided with a positioning surface.

[0018] The purpose of setting up a positioning surface is to achieve automated operation, in which the positioning surface can accurately position the loader.

[0019] The aforementioned split-type loader also includes a loading seat with a placement cavity that mates with the box body. The upper part of the placement cavity has a receiving cavity for accommodating the box lid. The box body is located within the placement cavity, and the box lid is located within the receiving cavity. Multiple positioning blocks arranged in a circular array are provided within the placement cavity to accommodate culture media of different diameters.

[0020] The loading seat is used to place the finished product loader. After the loader is placed in the loading seat, the upper surface of the loader should be lower than the upper surface of the loading seat, that is, the upper surface of the box cover should be lower than the upper surface of the loading seat.

[0021] In the aforementioned split-type loader, the upper surface of the loading seat has an adhesive area for attaching information label barcodes, and the adhesive area is located on the side of the receiving cavity.

[0022] Affixing the information label barcode to the designated area effectively ensures the accuracy of information about the microorganisms and the culture medium. Furthermore, since the area is located on the side of the container, the information label barcode will not obstruct observation of the culture medium's growth status.

[0023] In the aforementioned split-type loader, the outer periphery of the loading seat is provided with a positioning surface.

[0024] In the aforementioned split-type loader, the outer periphery of the loading seat is provided with a positioning angle.

[0025] Since the upper surface of the lid is lower than the upper surface of the loading seat, in order to facilitate the removal of the lid from the loading seat, an outlet communicating with the receiving cavity is provided on the loading seat. There are two outlets, which are arranged opposite to each other.

[0026] Compared with existing technologies, this split-type loader has the following advantages:

[0027] The structure is simple and adopts a split design, which reduces assembly steps and reduces the space occupied by the box after opening. After the lid is closed, the microorganisms inoculated on the culture medium can exchange air through the gap due to the support structure. The positioning surface can accurately position the loader in automated operation, which facilitates the realization of culture automation. The information marking is convenient and easy to observe, and the information marking barcode will not obstruct the observation of the growth status of the culture medium.

Detailed Implementation

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] Example 1

[0039] like Figure 1 and Figure 2 The split-type loader shown includes a rectangular box body 1 and a disc-shaped lid 2. A storage cavity 11 for storing culture medium is provided on the upper surface of the box body 1. A first annular flange 12 extending upward is provided around the outer periphery of the storage cavity 11. The lid 2 has a second annular flange 21. When the lid 2 is closed on the box body 1, the second annular flange 21 is located outside the first annular flange 12 and the second annular flange 21 is in clearance fit with the first annular flange 12. This can limit the lid 2 in the horizontal direction and prevent the lid 2 from falling off during movement.

[0040] like Figure 3 As shown, the outer side of the first annular flange 12 is a guide surface that slopes outward from top to bottom, making the outer diameter of the upper end of the first annular flange 12 smaller and the outer diameter larger towards the bottom, which makes it easier to place the lid 2 onto the box body 1.

[0041] like Figure 1 and Figure 2As shown, the upper surface of the box 1 has an adhesive area 13 for attaching information label barcodes. The adhesive area 13 is located on the side of the first annular edge 12, which can effectively ensure the accuracy of microbial and culture medium information. At the same time, the adhesive area 13 is located on the side of the first annular edge 12, so the information label barcode will not obstruct the observation of the growth status of the culture medium.

[0042] In this embodiment, in order to achieve automated operation, such as Figure 1 and Figure 2 As shown, the outer periphery of the box 1 is provided with a positioning surface 14, which can accurately position the loader during automated operation.

[0043] In order to enable microorganisms to exchange airflow, a support structure is provided between the box body 1 and the box cover 2 to allow the upper end face of the first annular flange 12 to fit with the inner top surface of the box cover 2 when the box cover 2 is closed.

[0044] In this embodiment, as Figure 2 and Figure 3 As shown, the support structure includes three protrusions 3 on the upper surface of the box body 1. The three protrusions are arranged in a circular array along the first annular flange 12. When the box cover 2 is closed, the lower end of the second annular flange 21 abuts against the protrusions 3.

[0045] The distance from the upper surface of the protrusion 3 to the upper surface of the first annular step is less than the distance from the lower end face of the second annular flange 21 to the inner top surface of the lid 2. The protrusion 3 supports the lid 2, and when the lid 2 is closed, the upper end face of the first annular flange 12 is in clearance fit with the inner top surface of the lid 2.

[0046] To ensure that the second annular retaining edge 21 can always press against the protrusion 3, the protrusion 3 is set in the shape of a strip and extends radially along the first annular retaining edge 12.

[0047] Example 2

[0048] like Figure 4 and Figure 6 The split-type loader shown includes a cylindrical box body 1 and a disc-shaped box cover 2. The box body 1 has a storage cavity 11 for storing culture medium inside. A first annular flange 12 extending upward is provided around the outer periphery of the storage cavity 11. The box cover 2 has a second annular flange 21. When the box cover 2 is closed on the box body 1, the second annular flange 21 is located outside the first annular flange 12 and the second annular flange 21 is in clearance fit with the first annular flange 12. This can limit the box cover 2 in the horizontal direction and prevent the box cover 2 from falling off during movement.

[0049] like Figure 6As shown, the outer side of the first annular flange 12 is a guide surface that slopes outward from top to bottom, making the outer diameter of the upper end of the first annular flange 12 smaller and the outer diameter larger towards the bottom, which makes it easier to place the lid 2 onto the box body 1.

[0050] To enable airflow exchange between microorganisms, a support structure is provided between the box body 1 and the lid 2 to allow the upper end face of the first annular flange 12 to engage with the inner top surface of the lid 2 when the lid 2 is closed. For example... Figure 6 and Figure 7 As shown, the support structure includes three protrusions 3 on the upper surface of the box body 1. The three protrusions are arranged in a circular array along the second annular flange 21. When the box lid 2 is closed, the upper end of the first annular flange 12 abuts against the protrusions 3. The box lid 2 is supported by the protrusions 3. When the upper end face of the first annular flange 12 abuts against the protrusions 3, the upper end face of the first annular flange 12 is in clearance fit with the inner top surface of the box lid 2. In order to ensure that the first annular flange 12 can always abut against the protrusions 3, the protrusions 3 are set in a strip shape and extend radially along the second annular flange 21.

[0051] like Figure 4 and Figure 5 As shown, it also includes a loading seat 4, which is used to place the finished product loader. The loading seat 4 has a placement cavity 41 that cooperates with the box body 1. The upper part of the placement cavity 41 forms a receiving cavity 42 for accommodating the box cover 2. The box body 1 is located in the placement cavity 41, and the box cover 2 is located in the receiving cavity 42. After the loader is placed into the loading seat 4, the upper surface of the loader is lower than the upper surface of the loading seat 4, that is, the upper surface of the box cover 2 is lower than the upper surface of the loading seat 4.

[0052] Since the upper surface of the lid 2 is lower than the upper surface of the loading seat 4, in order to facilitate the removal of the lid 2 from the loading seat 4, an outlet 44 communicating with the receiving cavity 42 is provided on the loading seat 4. There are two outlets 44 and they are arranged opposite to each other.

[0053] like Figure 4 and Figure 5 As shown, the upper surface of the loading seat 4 has an adhesive area 13 for affixing information label barcodes, and the adhesive area 13 is located on the side of the receiving cavity 42.

[0054] Affixing the information label barcode to the affixing area 13 can effectively ensure the accuracy of information about microorganisms and culture medium. At the same time, since the affixing area 13 is located on the side of the receiving cavity 42, the information label barcode will not obstruct the observation of the growth status of the culture medium.

[0055] like Figure 4 and Figure 5 As shown, the loading seat 4 has a positioning surface on its periphery.

[0056] like Figure 4 and Figure 5As shown, the loading seat 4 is provided with a positioning angle 43.

[0057] Example 3

[0058] The structural principle of this embodiment is basically the same as that of embodiment two, except that, as Figure 8 As shown, a plurality of positioning blocks 45 arranged in a circular array are provided in the placement cavity 41. The positioning blocks 45 are elongated and extend radially along the placement cavity 41. Each positioning block 45 has an inclined support surface at the upper part of its inner end, and the height of the support surface gradually increases from the inside to the outside. Because of the positioning blocks 45, the placement cavity 41 can be adapted to various sizes of boxes 1.
