Description

Technical Field

[0001] This application relates to the technical field of column ovens, and in particular to a column oven applicable to separation columns of different lengths. Background Art

[0002] A column oven, namely a chromatographic column thermostat, adjusts the temperature inside the cavity of the column oven to enable the chromatographic column to be in the best temperature usage condition, so as to better exert the separation ability, and is mainly applied to departments such as biology and biomedicine.

[0003] The separation column can be divided into three parts in appearance, namely the column head, the column body, and the column tail. Among them, the column body is the effective heat-receiving part of the separation column and needs to be in close contact with the column oven. The outer diameters of the column head and the column tail are larger than the outer diameter of the column body. During assembly, they are located outside the column oven. Usually, the inner diameter of the column groove of the column oven should be equal to the outer diameter of the column body, and the length of the column groove should be equal to or less than the length of the column body to ensure that the column body can be completely attached to the column groove.

[0004] In view of the above related technologies, the inventor found the following defects: The existing column oven cannot clamp and fix separation columns of different lengths, which easily causes the separation column not to fit with the column oven, resulting in difficulties in disassembling and assembling the separation column. Utility Model Content

[0005] In order to quickly clamp and fix the separation column body of different lengths, this application provides a column oven applicable to separation columns of different lengths.

[0006] A column oven applicable to separation columns of different lengths provided by this application adopts the following technical solutions: It includes a base and a number of fixing frames. The inner wall of each fixing frame is rotatably connected with a screw rod. The inner wall of each fixing frame is fixedly connected with a sliding rod. The inner wall of each fixing frame is slidably connected with a clamping plate. The inner wall of each clamping plate is threadedly connected with the corresponding screw rod. Each clamping plate is slidably connected to the outer surface of the corresponding sliding rod. The top of each screw rod is fixedly connected with a turning knob. The inside of each fixing frame is provided with a separation column body. The outer surface of each separation column body is clamped with the corresponding fixing frame. The upper surface of each fixing frame is fixedly connected with a baffle plate, and the upper surface of each baffle plate is fixedly connected with a handle.

[0007] Optionally, the upper surface of the base is fixedly installed with a column oven body. The inner wall of the column oven body is fixedly connected with a number of partition plates. The outer surface of each fixing frame is slidably connected with the corresponding partition plate.

[0008] Optionally, the outer surface of the column oven body is fixedly installed with a control panel. Both the left and right sides of the column oven body are fixedly installed with fans.

[0009] Optionally, a box door is hinged to the outer surface of the column oven body, and two connecting columns are fixedly connected to the inner wall of the column oven body. A spring is provided in the inner wall of each connecting column.

[0010] Optionally, a U-shaped push plate is provided inside the column oven body, and the outer surface of the U-shaped push plate is slidably connected to both connecting columns.

[0011] Optionally, one end of each spring close to the box door is fixedly connected to the U-shaped push plate, and the other end is fixedly connected to the corresponding connecting column.

[0012] Optionally, a power output block is slidably connected to the inner wall of the column oven body. The outer surface of the power output block is slidably connected to both connecting columns, and a temperature control tube is fixedly installed inside the power output block.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. By setting components such as a fixing frame, a screw rod, a sliding rod, a clamping plate, a baffle, a turning knob, a separation column body, and a handle, the separation column body is placed in the corresponding fixing frame, and then the turning knob is rotated. The turning knob will drive the corresponding clamping plate to move vertically along the corresponding screw rod. At this time, the clamping plate will slide vertically along the corresponding fixing frame and sliding rod, and then the clamping plate will clamp and fix the separation column body of different lengths. Then, the fixing frame carrying the separation column body is inserted into the column oven, thereby achieving the effect that the device can quickly clamp and fix the separation column body of different lengths through the movement of the clamping plate.

[0015] 2. By setting components such as a spring, a U-shaped push plate, a power output block, a temperature control tube, and a connecting column, the power output block is inserted along the column oven body. At this time, the power output block will squeeze the U-shaped push plate to make it slide horizontally along the two connecting columns, and the two springs will start to compress. When there is no external force, the springs will, under the action of their resilience, push the U-shaped push plate to push the power output block, thereby achieving the effect that the device can quickly push out the power output block through the setting of the springs.

Detailed implementation mode

[0021] The following will Figure 1 - Figure 4 make a further detailed description of this application.

[0022] The embodiment of this application discloses a column oven applicable to separation columns of different lengths. As Figure 1 shown, it includes a base 1 and several fixing frames 5. The upper surface of the base 1 is fixedly installed with a column oven body 2, and the column oven body 2 can place the separation column body 12. The inner wall of the column oven body 2 is fixedly connected with several partitions 13, and the outer surface of each fixing frame 5 is slidably connected with the corresponding partition 13. The arrangement of the partitions 13 enables the partitions 13 to divide the interior of the column oven body 2, and the outer surface of the partitions 13 is provided with filter holes.

[0023] Please refer to Figure 3 , Figure 4 . The outer surface of the column oven body 2 is fixedly installed with a control panel 4, and fans 19 are fixedly installed on both the left and right sides of the column oven body 2. The control panel 4 can control the fans 19. When the fans 19 are started, they will blow air into the column oven body 2. At this time, the air flow inside the column oven body 2 will circulate, facilitating the uniform adjustment of the temperature inside the column oven body 2.

[0024] Please refer to Figure 1 , Figure 3 . The inner wall of each fixing frame 5 is rotatably connected with a screw 9, the inner wall of each fixing frame 5 is fixedly connected with a slide bar 10, the inner wall of each fixing frame 5 is slidably connected with a clamping plate 11, and the inner wall of each clamping plate 11 is threadedly connected with the corresponding screw 9. By rotating the screw 9, the screw 9 will drive the corresponding clamping plate 11 to move vertically along the corresponding screw 9. At this time, the clamping plate 11 will slide vertically along the corresponding slide bar 10 and fixing frame 5.

[0025] Please refer to Figure 1 , Figure 3, each clamping plate 11 is slidably connected to the outer surface of the corresponding sliding rod 10. The top end of each screw rod 9 is fixedly connected with a knob 8. A separating column body 12 is arranged inside each fixing frame 5. By rotating the knob 8, the knob 8 can facilitate the rotation of the corresponding screw rod 9. The setting of the sliding rod 10 can limit the corresponding clamping plate 11.

[0026] Please refer to Figure 1 、 Figure 3 , the outer surface of each separating column body 12 is clamped with the corresponding fixing frame 5. A baffle 6 is fixedly connected to the upper surface of each fixing frame 5. A handle 7 is fixedly connected to the upper surface of each baffle 6. A card slot is opened at the bottom end of each fixing frame 5. By placing the separating column body 12 in the card slot inside the corresponding fixing frame 5 and then rotating the knob 8, at this time the clamping plate 11 can clamp and fix the separating column bodies 12 of different lengths. When the fixing frame 5 is completely inserted into the column temperature box body 2, the baffle 6 will close the cavity where the corresponding fixing frame 5 is located. The setting of the handle 7 can facilitate the extraction of the fixing frame 5.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , a box door 3 is hinged to the outer surface of the column temperature box body 2. An electric power output block 17 is slidably connected to the inner wall of the column temperature box body 2. The outer surface of the electric power output block 17 is slidably connected to both connecting columns 14. A temperature control tube 18 is fixedly installed inside the electric power output block 17. When the box door 3 is opened, the electric power output block 17 can be put into the column temperature box body 2. During this process, the electric power output block 17 can slide horizontally along the two connecting columns 14. Through the setting of the temperature control tube 18, the temperature inside the column temperature box body 2 can be adjusted quickly.

[0028] Please refer to Figure 2 , two connecting columns 14 are fixedly connected to the inner wall of the column temperature box body 2. A spring 15 is arranged inside the inner wall of each connecting column 14. One end of each spring 15 close to the box door 3 is fixedly connected to a U-shaped push plate 16, and the other end is fixedly connected to the corresponding connecting column 14. A U-shaped push plate 16 is arranged inside the column temperature box body 2. The outer surface of the U-shaped push plate 16 is slidably connected to both connecting columns 14. By inserting the electric power output block 17 into the column temperature box body 2, at this time the electric power output block 17 will push the U-shaped push plate 16 to make it slide horizontally along the two connecting columns 14. At this time, the two springs 15 start to compress simultaneously. When there is no external force acting on the U-shaped push plate 16, the spring 15 will push the U-shaped push plate 16 to reset under the action of its resilience force. During this process, the U-shaped push plate 16 will push out the electric power output block 17, which is convenient for disassembling the electric power output block 17.

[0029] The implementation principle of a column oven applicable to separation columns of different lengths in an embodiment of this application is as follows: First, insert the power output block 17 into the column oven body 2. At this time, the power output block 17 will push the U-shaped push plate 16 to slide horizontally along the two connecting columns 14. At this time, the two springs 15 will start to compress simultaneously. Then close the door 3. At this time, the power output block 17 will be installed inside the column oven body 2. Then start the fan 19 through the control panel 4. The fan 19 will make the air flow inside the column oven body 2 circulate, so as to facilitate the uniform adjustment of the temperature inside the column oven body 2. Then place the separation column body 12 in the card slot inside the corresponding fixing frame 5 and turn the knob 8. The knob 8 will drive the corresponding screw rod 9 to rotate. The screw rod 9 will drive the corresponding clamping plate 11 to move vertically along the corresponding screw rod 9. At this time, the clamping plate 11 will slide vertically along the corresponding slide rod 10 and the fixing frame 5. At this time, by moving the clamping plate 11, the separation column body 12 of different lengths can be clamped and fixed. Finally, insert the fixing frame 5 with the separation column body 12 into the cavity inside the column oven body 2.

[0030] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
