Description

Technical Field

[0001] The utility model relates to the technical field of gel imagers, in particular to a gel imager. Background Art

[0002] Gel imaging is mainly used for protein and nucleic acid gel imaging and analysis. The system provides white light, ultraviolet light and blue light sources to shoot gels. The system's built-in image capture software captures the images, and then the system's built-in image analysis software analyzes the images.

[0003] Gel imaging is the process of imaging the gel using a gel imager and then performing data conversion. The gel imager is a high-tech product and a high-end molecular biological analysis instrument that requires close coordination of software and hardware. During the test, the prepared gel plate is placed in the gel imager, then the gel imager is closed and the power of the gel imager is turned on to image the gel plate.

[0004] When using a gel imager, only a single gel plate can be imaged at a time. When imaging multiple gel plates, the device needs to be opened multiple times, resulting in increased wear and tear of the gel imager and a longer time consumption. Therefore, it does not meet existing needs. In this regard, we propose a gel imager. Utility Model Content

[0005] The utility model aims to provide a gel imager to solve the problems raised in the above-mentioned background technology that when using the gel imager, only a single gel plate can be imaged at a time, and when imaging multiple gel plates, the device needs to be opened multiple times, resulting in increased wear and tear of the gel imager and a long time consumption.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gel imager, comprising an equipment body, a movable box is slidably installed on the front surface of the equipment body, a placement table is detachably installed on the surface of the movable box, a storage groove is opened on the surface of the placement table, a lifting frame is slidably installed on the inner side of the storage groove, a plurality of placement plates distributed at equal intervals up and down are fixed to the inner side of the lifting frame, an electric telescopic rod is fixed on the surface of the placement table, and a push bar is fixed to the movable end of the electric telescopic rod.

[0007] Preferably, the spacing dimension between the two downwardly adjacent placement plates is greater than or equal to the thickness dimension of the gel plate, and the thickness dimension of the push bar is consistent with the spacing dimension between the two upwardly and downwardly adjacent placement plates.

[0008] Preferably, the edges of the upper and lower surfaces on both sides of the placement plate are inclined surfaces with a forty-five angle, and the push strip is made of rubber material.

[0009] Preferably, a V-shaped groove is formed on the side of the push bar facing the placement plate, and the middle and edge of the V-shaped groove are both arc surfaces.

[0010] Preferably, a guide groove is provided on the inner wall of the storage groove, a guide screw rod is installed on the inner side of the guide groove, and both ends of the guide screw rod are inserted into the placement table and connected to the placement table through roller bearings.

[0011] Preferably, the top end of the guide screw is connected to a driving motor, the driving motor is fixed inside the placement table and the output shaft end is fixed to the guide screw.

[0012] Preferably, a lifting slider is sleeved on the outer side of the guide screw rod, and the lifting slider is connected to the guide screw rod by threads and one end of the lifting slider is fixed to the bottom side of the lifting frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. After the movable box body is closed, the imager is powered on and started. After starting, the driving motor is energized and drives the guide screw to rotate counterclockwise. At this time, the guide screw will drive the lifting slider and the lifting frame to move up. At this time, the lifting frame extends from the storage slot to drive the placement plate to move up until the bottom of the gel plate on the uppermost layer is flush with the surface of the placement table. At this time, the guide screw stops running, and then the electric telescopic rod pushes the pushing bar to approach the gel plate, so that the pushing bar passes between two adjacent placement plates and pushes the gel plate away from the placement plate, and the gel plate will move to just below the imaging lens of the imager, and then the electric telescopic rod drives the pushing bar to reset. After the pushing bar is reset, the driving motor continues to drive the guide screw to rotate, so that the lifting frame rises again to send another gel plate to be detected from the storage slot. After the previous gel plate is detected, the electric telescopic rod pushes the pushing bar to move again, and the pushing bar pushes the new gel plate to the bottom of the imaging lens and pushes the original gel plate away. Repeating the above operation can continuously detect all installed gel plates. There is no need to open the imager during the detection process, saving operation time and improving work efficiency.

[0015] 2. The utility model has a V-shaped groove on the side of the push bar facing the placement plate. The V-shaped groove allows the side of the push bar facing the placement plate to bend and deform toward the middle, ensuring that the push bar can smoothly enter between two adjacent placement plates when moving, and will not be blocked by the edge of the placement plate and unable to move.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 4 As shown, an embodiment of the utility model is: a gel imager, including an equipment body 1, a movable box 2 is slidably installed on the front surface of the equipment body 1, a placing table 3 is detachably installed on the surface of the movable box 2, a storage groove 4 is opened on the surface of the placing table 3, a lifting frame 5 is slidably installed on the inner side of the storing groove 4, a plurality of placing plates 6 distributed at equal intervals up and down are fixed on the inner side of the lifting frame 5, an electric telescopic rod 7 is fixed on the surface of the placing table 3, a pushing bar 12 is fixed on the movable end of the electric telescopic rod 7, the spacing dimension between two adjacent placing plates 6 downward is greater than or equal to the thickness dimension of the gel plate, the thickness dimension of the pushing bar 12 is consistent with the spacing dimension between two adjacent placing plates 6 up and down, when the electric telescopic rod 7 is used to push the pushing bar 12 to slide on the surface of the placing table 3, the pushing bar 12 can pass through between the two placing plates 6 and push out the gel plate located between the two adjacent placing plates 6, and push the gel plate to the bottom of the imaging lens for detection.

[0023] The edges of the upper and lower surfaces on both sides of the placement plate 6 are both 45-degree angle slopes. The push bar 12 is made of rubber material. A V-shaped groove is opened on the side of the push bar 12 facing the placement plate 6. The middle and edges of the V-shaped groove are both arc surfaces. The slope at the edge of the placement plate 6 is used to guide the push bar 12 when the push bar 12 contacts the placement plate 6, so that the push bar 12 can smoothly enter between two adjacent placement plates 6, and the edge of the push bar 12 will not be blocked by the placement plate 6 and cannot enter between the adjacent placement plates 6.

[0024] A guide slot 8 is provided on the inner wall of the storage groove 4, and a guide screw 10 is installed on the inner side of the guide slot 8. Both ends of the guide screw 10 are inserted into the placement table 3 and connected to the placement table 3 through roller bearings. The top of the guide screw 10 is connected to a driving motor 11, and the driving motor 11 is fixed inside the placement table 3 and the output shaft end is fixed to the guide screw 10. A lifting slider 9 is sleeved on the outer side of the guide screw 10. The lifting slider 9 is connected to the guide screw 10 through threads and one end is fixed to the bottom side of the lifting frame 5. The driving motor 11 is used to drive the guide screw 10 to rotate, and the height of the lifting slider 9 and the lifting frame 5 can be adjusted, thereby changing the position of the gel plate placed on the placement plate 6.

[0025] Working principle: first, pull out the movable box 2 from the equipment body 1, and then the staff will place the gel plate to be tested between two adjacent placement plates 6, then close the movable box 2 and turn on the power of the drive motor 11. After the drive motor 11 is started, it will drive the guide screw 10 to rotate clockwise. When the guide screw 10 rotates, it will drive the lifting slider 9 and the lifting frame 5 to descend until the lifting frame 5, the placement plate 6 and the gel plate placed on the placement plate 6 are completely entered into the storage slot 4. After the movable box 2 is closed, the imager power is turned on and started. After starting, the drive motor 11 is energized and drives the guide screw 10 to rotate counterclockwise. At this time, the guide screw 10 will drive the lifting slider 9 and the lifting frame 5 to move up. At this time, the lifting frame 5 extends from the storage slot 4 to drive the placement plate 6 to move up until the bottom of the gel plate on the top layer is flush with the surface of the placement table 3. At this time, the guide The screw rod 10 stops running, and then the electric telescopic rod 7 pushes the pushing bar 12 to approach the gel plate, so that the pushing bar 12 passes between the two adjacent placement plates 6 and pushes the gel plate off the placement plates 6, and the gel plate will move to just below the imaging lens of the imager, and then the electric telescopic rod 7 drives the pushing bar 12 to reset. After the pushing bar 12 is reset, the driving motor 11 continues to drive the guide screw rod 10 to rotate, so that the lifting frame 5 rises again to send another gel plate to be tested from the storage slot 4. After the previous gel plate is tested, the electric telescopic rod 7 pushes the pushing bar 12 to move again, and the pushing bar 12 pushes the new gel plate to the bottom of the imaging lens and pushes the original gel plate away. Repeating the above operation can continuously detect all installed gel plates. There is no need to open the imager during the detection process, which saves operation time and improves work efficiency.
