[0015] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0016] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a rotary evaporator condenser flask with a quick-assembly and disassembly structure. Example

[0017] For easier understanding, please refer to Figures 1 to 4This utility model provides an embodiment of a rotary evaporator condenser flask with a quick-assembly and disassembly structure, comprising a flask body 1, on which an installation mechanism is provided; the installation mechanism includes a fixing ring 2, a first fixing plate 4, an installation groove 5, a lever 6, a locking screw 7, an eccentric wheel 8, and a fixing block 9. The fixing ring 2 is fixedly installed at one end of the flask body 1, the first fixing plate 4 is fixedly installed at one end of the fixing ring 2, the installation groove 5 is opened at one end of the first fixing plate 4, the locking screw 7 is threadedly connected to the inside of the installation groove 5, the eccentric wheel 8 is fixedly installed at one end of the locking screw 7, the lever 6 is fixedly installed at the other end of the locking screw 7, and the fixing block 9 is rotatably installed on the outer wall of the eccentric wheel 8.

[0018] In this example, an external connection port 13 is also included, which is located at the connection between the rotary evaporator and the bottle body 1.

[0019] It should be noted that by setting up the installation mechanism, the fixing ring 2 is aligned with the connection port 13 and inserted into one end. The lever 6 is pressed down by hand, and the lever 6 drives the eccentric wheel 8 to rotate. When the eccentric wheel 8 rotates, it pushes the fixing block 9, so that one side of the fixing block 9 presses against one side of the inner wall of the moving frame 11 and pushes the moving frame 11 to move deeper into the installation groove 5, so that one end of the second fixing plate 10 presses against one end of the first fixing plate 4, so that the bottle body 1 can be quickly disassembled and installed, improving the operational efficiency of the bottle body 1 installation.

[0020] In this example, the first fixing plate 4 and the second fixing plate 10 form a complete ring after being closed.

[0021] In this example, the connection between the retaining ring 2 and the bottle body 1 is made by using food-grade high-temperature resistant adhesive.

[0022] In this example, fixed block 9 is hexagonal.

[0023] In some embodiments, such as Figure 3 As shown, a threaded hole is provided on one side wall of the first fixing plate 4. The threaded hole is connected to the inside of the mounting groove 5. The locking screw 7 is threaded to the inner wall of the threaded hole. The eccentric wheel 8 and the fixing block 9 are located inside the mounting groove 5. The lever 6 is located outside the first fixing plate 4.

[0024] It should be noted that the thread specification of the threaded hole is compatible with the locking screw 7. When the lever 6 is pressed down or pried up, the lever 6 drives the eccentric wheel 8 to rotate through the locking screw 7. By setting the locking screw 7, the angle of the lever 6 is fixed when the lever 6 is not pried by hand.

[0025] In some embodiments, such as Figure 4 As shown, a second fixed plate 10 is rotatably mounted on the other end of the first fixed plate 4, and a movable frame 11 is fixedly mounted on one end of the second fixed plate 10. The movable frame 11 is located inside the mounting groove 5, and the eccentric wheel 8 and the fixed block 9 are located inside the movable frame 11.

[0026] It should be noted that the inner wall of the movable frame 11 needs to be smoothed to reduce the frictional resistance between it and the eccentric wheel 8 and the fixed block 9, so as to ensure that the movable frame 11 can slide smoothly when the lever 6 is pressed.

[0027] In some embodiments, such as Figure 2 As shown, a sealing ring 3 is fixedly installed on the inner wall of the fixing ring 2, and several protrusions 12 are fixedly installed on one side of the first fixing plate 4 and the second fixing plate 10.

[0028] It should be noted that the outer wall of the connection port 13 has several slots. When the first fixing plate 4 and the second fixing plate 10 are closed, the protrusions 12 on them are engaged in the slots on the outer wall of the connection port 13, so that the bottle body 1 is installed on the connection port 13 and the sealing ring 3 is pressed on one end of the connection port 13 to seal the connection between the connection port 13 and the bottle body 1.

[0029] Working principle: When disassembling bottle 1, manually turn lever 6 counterclockwise to drive locking screw 7 outward along threaded hole. Eccentric wheel 8 moves and rotates synchronously with locking screw 7, and its squeezing force on moving frame 11 gradually disappears, the fixation of one end of first fixing plate 4 and second fixing plate 10 is removed, the clamping force between first fixing plate 4 and second fixing plate 10 is removed, and then bottle 1 is removed.

[0030] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
