Abstract
Description
Technical Field
[0001] This application belongs to the field of biological detection, and specifically relates to a multifunctional transfer box connector mounting structure and a multifunctional transfer instrument module. Background Technology
[0002] There are two main transfer methods: wet transfer and semi-dry transfer. The main difference between wet and semi-dry transfer lies in their working principles and operation methods. Wet transfer involves immersing the membrane, gel, and filter paper entirely in buffer solution, while semi-dry transfer uses filter paper to absorb the buffer solution. Wet transfer typically requires more buffer solution and is relatively more complex to operate, but it is more adaptable, offers better temperature control, and is less prone to errors. In contrast, semi-dry transfer requires less buffer solution and is simpler to operate, but it is more susceptible to failure due to membrane drying. Some transfer instruments combine wet and semi-dry transfer, continuously replenishing the buffer solution during the semi-dry transfer phase to create a wet transfer environment, thereby achieving the transfer.

[0023] The following description, in conjunction with the accompanying drawings, further illustrates the scheme of this application.
[0024] like Figure 1As shown, this application embodiment provides a multifunctional transfer cartridge connector mounting structure, including a first fixing mechanism 100. The first fixing mechanism 100 includes a first fixing base 101, and the first fixing base 101 is provided with a first through hole 102 for the transfer cartridge liquid connector to pass through. In some embodiments, the first fixing base 101 of this application protrudes in a direction away from the second fixing base 201 to form a first boss 103. The first boss 103 and the second fixing base 201 form a first cavity 110, which is used to accommodate one end of the connector 3.
[0025] like Figure 1 As shown, in some embodiments, fixing ears 104 are provided on both sides of the first boss 103. The fixing ears 104 are provided with fourth through holes 105 for the first fixing member 106 to pass through. The two fourth through holes 105 are located on both sides of the first boss 103. The first fixing member 106 passes through the fourth through holes 105 to fix the first fixing base 101 and the second fixing base 201.
[0026] like Figure 1 and Figure 2 As shown, the second fixing mechanism 200 in this embodiment includes a second fixing base 201. In some embodiments, the second fixing base 201 is a strip-shaped structure. The first fixing base 101 is fixed on the second fixing base 201 by a first fixing member 106. The second fixing base 201 is provided with a second through hole 202 for the connector 3 to pass through.
[0027] In some embodiments, the second fixing base 201 is provided with a third through hole 203 for the second fixing member 204 to pass through. In some embodiments, the third through holes 203 are located on both sides of the second fixing base 201, and the second through hole 202 is located between the two third through holes 203. The second fixing base 201 of this application is mounted on the fixing substrate 300. In some embodiments, the first fixing member 106 and the second fixing member 204 in this application can be selected as screws or screw structures with end caps.
[0028] In some embodiments, the diameter of the second fixing member 204 is smaller than the diameter of the third through hole 203. The second fixing member 204 achieves axial fixation of the second fixing base 201. Since the diameter of the second fixing member 204 is smaller than the diameter of the third through hole 203, the second fixing base 201 can be adjusted in position around the second fixing member 204 with a slight range.
[0029] like Figure 1 and Figure 2As shown, in this embodiment, the fixed base plate 300 is a mounting plate structure. An adjusting element 400 is provided between the second fixed base 201 and the fixed base plate 300. Both ends of the adjusting element 400 abut against the fixed base plate 300 and the second fixed base 201, respectively. In some specific embodiments, the adjusting element 400 is a spring structure. A first groove 301 is provided on the fixed base plate 300. One end of the adjusting element 400 abuts against the bottom surface of the first groove 301, and the other end abuts against the second fixed base 201. The adjusting element 400 can further fix the second fixing mechanism 200, preventing the second fixing mechanism 200 from shaking due to the difference in hole diameter between the third through hole 203 and the second fixing member 204, and does not affect the adjustment of the position of the second fixing mechanism. In some specific embodiments, the adjusting element 400 is located between the second fixing member 204 and the first boss 103, with both ends abutting against the second fixed base 201 and the fixed base plate 300, respectively.
[0030] like Figure 1 and Figure 2 As shown, the connector 3 of this application includes a first connecting seat 301 and a second connecting seat 302. The diameter of the first connecting seat 301 is smaller than the diameter of the second through hole 202, and the diameter of the second connecting seat 302 is larger than the diameter of the second through hole 202. The first connecting seat 302 passes through the second through hole 202, and the second fixing base 201 is locked between the first connecting seat 301 and the second connecting seat 302, thus fixing the connector 3 and the second fixing base 201. The first connecting seat 301 of the connector 3 is located between the first cavity 110 formed by the first boss 301. The first fixing base 101 and the second fixing base 102 together fix the connector 3. The fine adjustment of the position of the second fixing base 201 ensures that the installation position of the connector 3 can be finely adjusted. Figure 2 As shown, the connector 3 of this application is provided with a connection hole 303 on one side of the first connector 301. The connection hole 303 is used to connect with the liquid connector on the transfer box.
[0031] In some embodiments, the diameter of the first through hole 102 of this application is larger than the diameter of the liquid connector, and the diameter of the first through hole 102 gradually decreases along the thickness direction of the first fixed base 101. The inner wall of the first through hole 102 forms a frustum structure, which forms a guide mechanism. When the liquid connector of the transfer film box of this application passes through the first through hole 102 and is inserted into the connection hole 303, since the diameter of the first through hole 102 is larger than the diameter of the liquid connector, the situation where the liquid connector cannot be inserted into the first through hole 102 due to tolerances in the processing is avoided. The inner wall of the first through hole 102 forms a guide mechanism, which facilitates the insertion of the liquid connector. The connector 3 connected to the liquid connector can be finely adjusted. The adjusting element 400 has a floating support function for the second fixed base 201. The first through hole 102 on the first fixed base 101 has a certain guiding angle, which ensures that the liquid connector and the connector 3 can be smoothly connected when the transfer film box is inserted.
[0032] This application embodiment also provides a multifunctional transfer film device module, including a transfer film box 1 and a transfer film device mounting bracket 2 for fixing the transfer film box 1. A liquid connector is provided on the transfer film box 1, and the liquid connector is connected to the connector 3 through a multifunctional transfer film box connector mounting structure.
[0033] like Figure 3 As shown, the multifunctional transfer apparatus module has a first direction X, the transfer apparatus mounting frame 2 has a receiving cavity for accommodating the transfer container 1, the transfer container is inserted into the transfer apparatus mounting frame 2 along the first direction X, and two liquid connectors on the transfer container are inserted into connectors 3 located on the fixed substrate 300. The other end of the connectors 3 is connected to a buffer solution inlet or outlet mechanism.
[0034] like Figure 4 As shown, the transfer cartridge 1 has two liquid connectors, namely a first liquid connector 110 and a second liquid connector 120. The first liquid connector 110 is used to feed buffer into the transfer cartridge 1, and the second liquid connector 120 is used to discharge waste liquid from the transfer cartridge 1. The first liquid connector 110 and the second liquid connector 120 are respectively connected to the corresponding connectors 3.
[0035] The transfer container and multifunctional transfer instrument module of this application have multiple uses, such as performing membrane transfer and staining. Furthermore, the multifunctional transfer instrument module in this embodiment integrates multiple modules to allow for simultaneous execution of multiple experiments, enabling membrane transfer and staining to be performed simultaneously in one instrument. To avoid misassembly of the transfer container, the transfer container 1 of this application is equipped with identification sites.
[0036] like Figures 3-6As shown, in some embodiments, the transfer box 1 has a first identification point 130 on the positive electrode module and a second identification point 140 on the negative electrode module 1. Both the first identification point 130 and the second identification point of the transfer box used for transfer are protrusion structures. When the two protrusions abut against the identification point of the identification mechanism, the identification point is displaced, and the first identification mechanism 4 determines whether the positive and negative electrode modules used for transfer are correct. In some embodiments, the first identification mechanism 4 includes two optocouplers as identification elements of the identification mechanism, and corresponding to the two optocouplers are two elastic pin mechanisms 401 used to identify the insertion of the transfer box.
[0037] Meanwhile, the identification point of the transfer box used for dyeing is set as a concave point. When the transfer box is misinstalled, one of the two optocouplers' pin mechanisms 401 will not be displaced, and the first identification mechanism 4 can make a misjudgment.
