Abstract
Description
Technical Field
[0001] This utility model relates to the field of protein transfer equipment technology, specifically a rapid protein transfer device. Background Technology
[0002] The principle of protein transfer is to use an electric field to transfer proteins from a gel to a solid support (such as an NC membrane or a PVDF membrane). During the transfer process, the electric field is perpendicular to the gel and the membrane, causing the negatively charged proteins to be released under the influence of the current. Through interaction with the transfer membrane, they are firmly adsorbed and fixed on the membrane, maintaining their relative position in the gel.
[0003] The prior art publication number CN209513819U discloses a rapid protein transfer device, comprising a transfer chamber with an electrode interface at one end. Inside the transfer chamber is a carrier plate fixed within the chamber, and the carrier plate has a fitting groove into which a transfer box is fitted. An electrode tip is located on the inner wall of one end of the fitting groove, and this electrode tip is connected to the electrode interface via an electrode wire. One end of the transfer box has an electrode connector, and electrode plates are located inside the transfer box, each fixed to the internal interface of the electrode connector. This design allows for simple transfer; during transfer, the transfer box containing the material is simply inserted into the fitting groove of the carrier plate, and the electrode connector on the transfer box engages with the electrode tip on the groove wall. Electrodes can then be directly connected via the electrode interface. This method simplifies the cumbersome process of manually connecting electrodes and shortens the transfer time.
[0004] With the above setup, the existing protein transfer device, by setting up a transfer box and a transfer container, allows the gel and membrane to connect with the electrode plates inside the transfer container when the material is first loaded into the transfer container in a specific order. During transfer, the transfer container containing the material is simply inserted into the fitting groove of the carrier plate, and the electrode connector on the transfer container connects with the electrode tip on the groove wall, allowing direct electrode connection via the electrode interface. However, the existing protein transfer device has the following drawbacks during operation:
[0005] When using the protein transfer device described in the prior art, the transfer box containing the material needs to be embedded into the fitting groove first, and then an external power supply is used to electrically connect to the electrode connector through the electrode interface. However, due to the mismatch between the size of the electrode interface and the electrode connector, it is quite troublesome to connect the external power supply. It requires manual connection by the operator, which is very cumbersome. Moreover, the external power supply is prone to detachment from the electrode connector after being hit, which can easily damage the electrode connector. Utility Model Content
[0006] The present invention aims to provide a rapid protein transfer device, which mainly solves the technical problem that the external power supply is cumbersome to connect to the electrode connector through the electrode interface in the existing technology, and is also prone to detachment from the external power supply and electrode connector, causing damage to the electrode connector.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A rapid protein transfer device includes a transfer chamber, a carrier plate, and a transfer box. The carrier plate is fixed to the inner wall of the transfer chamber, and a placement groove is formed on the upper surface of the carrier plate. The transfer box is located inside the placement groove, and multiple support legs are fixedly connected to the upper surface of the transfer box. The bottom surface of the transfer box abuts against the top surface of the support legs. An insertion port is provided on one side of the transfer box, and a movable groove is formed on the inner wall of one side of the transfer chamber. A plug-in component is installed inside the movable groove.
[0009] The working principle and beneficial effects of this utility model:
[0010] 1. Working principle: When rapid protein transfer is required, first pull the slide bar. The slide bar moves the L-shaped plate and compresses the spring. Then, one of the transfer boxes is placed into the placement slot, and the other transfer boxes are stacked inside the transfer chamber. Then, release the slide bar. Under the action of the spring return force, the L-shaped plate moves the plug into the socket. Then, connect the power connector to the conductive terminal and adjust the limiting component. At this time, rapid protein transfer can be performed.
[0011] 2. Beneficial effects:
[0012] Existing technologies, through the use of a transfer chamber and transfer box, allow for direct connection of the gel and membrane to the electrode plates within the transfer box when materials are loaded in a specific order. During transfer, the transfer box containing the material is simply inserted into the fitting slot of the carrier plate, and the electrode connectors on the transfer box connect to the electrode terminals on the groove wall. Electrode connection is achieved directly through the electrode interface. However, existing protein transfer devices require the material-loaded transfer box to be inserted into the fitting slot first, followed by an external power supply connected to the electrode connectors via the electrode interface. This connection is cumbersome due to the size mismatch between the electrode interface and the electrode connectors, necessitating manual intervention. The previous manual connection process was cumbersome, and the external power supply was prone to detachment from the electrode connector after impact, potentially damaging the connector. This solution addresses this issue by using a transfer box, a plug-in assembly, and a limiting assembly. The plug-in assembly electrically connects the transfer box, allowing the plug to be inserted into the socket. Then, the external power connector is connected, enabling rapid protein transfer. The limiting assembly secures the external power connector, effectively preventing it from detaching and damaging the socket. The installation and removal of the transfer box are quick and easy, and three transfer boxes can be operated simultaneously, significantly improving operational efficiency.
[0013] Preferably, the plug-in assembly includes an L-shaped plate with a fixed cavity inside. The L-shaped plate is slidably connected to a movable groove. A compression spring is fixedly connected to the inner wall of the movable groove, and the other end of the compression spring is fixedly connected to the L-shaped plate. A slide rod is fixedly connected to one side of the L-shaped plate, passing through the transfer chamber and slidably connected thereto. A conductive plate is fixedly connected to the inner wall of the fixed cavity. Multiple plugs are fixedly connected to one side of the conductive plate, passing through the L-shaped plate and fixedly connected thereto. The plugs are inserted into corresponding sockets. A conductive terminal is fixedly connected to one end of the conductive plate, and a power connector is inserted into the outer wall of the conductive terminal. A limiting assembly for fixing the power connector is fixedly connected to the outer wall of the transfer chamber. By setting the plug-in assembly, the plugs and sockets can be tightly connected. Then, by inserting the power connector into the conductive terminal, power can be supplied to the transfer chamber, thereby realizing the rapid transfer of proteins.
[0014] Preferably, the limiting component includes a fixed block, a movable groove on one side of the fixed block, a limiting block slidably connected to the inner wall of the movable groove, symmetrical pull rods fixedly connected to the end of the limiting block away from the power connector, the pull rods passing through the fixed block and slidably connected to it, a limiting spring fixedly connected to the outer wall of the pull rods, one end of the limiting spring fixedly connected to the limiting block, the other end of the limiting spring fixedly connected to the movable groove, a pull plate fixedly connected to the end of the pull rod away from the limiting block, and a limiting groove on one side of the power connector, with the limiting block inserted into the limiting groove. By setting the limiting component, the power connector can be fixed, preventing the power connector from detaching from the conductive terminals when pulled, thus avoiding damage to the conductive terminals.
[0015] Preferably, the upper surface of the transfer box is symmetrically provided with sliding grooves, and the outer wall of the transfer box is fixedly connected with symmetrical sliders, which are slidably connected to the sliding grooves. By setting the sliding grooves and sliders, the transfer box can be limited to prevent it from moving and causing the plug to be unable to be inserted into the socket.
[0016] Preferably, the inner wall of the movable groove is symmetrically provided with guide grooves, and a guide block is slidably connected to the inner wall of the guide groove. The guide block is fixedly connected to the L-shaped plate. By providing guide grooves and guide blocks, the L-shaped plate can be limited, preventing the L-shaped plate from detaching from the movable groove.
[0017] Preferably, the transfer boxes are stacked vertically, and there are three transfer boxes. This improves work efficiency. Attached Figure Description
