Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and more specifically, to a self-locking clamping device for automated synthesis rotary evaporators. Background Technology

[0002] Rotary evaporators are crucial equipment in laboratories for vacuum distillation, and their core component, the rotary evaporator flask, requires clamping for secure fixation. Current technologies often employ plastic clips or rubber sleeves for flask clamping. These materials are prone to expansion and deformation after prolonged heating, creating gaps between the flask and the fixing device. This severely compromises the airtightness of the apparatus and can lead to solvent leakage during vacuum distillation. Furthermore, these clamping mechanisms are often inconvenient to assemble and disassemble, limiting operating space and requiring both hands to lock or unlock, significantly reducing experimental efficiency, especially in automated synthesis processes requiring multi-angle rotation.

[0003] To address the aforementioned issues, some improvements have been implemented in existing technologies, such as using clamping mechanisms with snap-fit ​​and locking mechanisms, or enhancing the fixation of the rotary evaporator flask with limiting heads. However, these structures still suffer from insufficient stability and inadequate limiting accuracy, and there is still a risk of loosening or shifting during high-speed rotation of the rotary evaporator flask. They cannot fully meet the high standards of coaxiality and ease of operation required by automated synthesis processes. Therefore, a novel clamping device is needed that enables rapid and reliable one-handed operation at any rotation angle, while ensuring coaxiality and stability of the connection.

[0031] In practical use, the self-locking clamping device for automated synthesis rotary evaporators according to this utility model includes a fixing component 2 and a connecting component 3.

[0032] The fixing component 2 is installed on the neck of the fixed rotary evaporator 1. The fixing component 2 includes two male half-clamping blocks 6, a male locking ring 7, a male sealing element 5, and a male fastener 8. The inner ring of the male half-clamping block 6 has two grooves and two positioning holes, and the male locking ring 7 has two positioning holes.

[0033] The connecting assembly 3 includes a female port assembly 15, a sliding collar 13, a limiting assembly 14, and a snap-fit ​​assembly. The female port assembly 15 is fixedly installed on the neck of the connecting rotary evaporator 4 and includes two female port half-clamping blocks 10, a female port locking ring 11, a female port sealing element 9, and a female port fastener 12. The inner ring of the female port half-clamping block 10 has two grooves and two positioning holes, and the female port locking ring 11 has two positioning holes. During installation, firstly, the female port sealing element 9 is embedded in the groove of the female port half-clamping block 10, then the two female port half-clamping blocks 10 are installed at the neck position of the female port of the connecting rotary evaporator 4, then the female port locking ring 11 is fitted onto the female port half-clamping blocks 10, and finally the female port fastener 12 is screwed into the positioning holes of the female port locking ring 11 and the female port half-clamping block 10 to complete the installation of the female port assembly 15, so that the female port assembly 15 and the connecting rotary evaporator 4 rotate coaxially and synchronously.

[0034] The sliding collar 13 is sleeved on the female connector assembly 15 and can move axially on the female connector assembly 15. A keyway structure is provided between the sliding collar 13 and the female connector locking ring 11 to cooperate with each other. This structure allows the sliding collar 13 to rotate coaxially and synchronously on the female connector assembly 15.

[0035] The limiting component 14 is disposed between the female connector component 15 and the sliding collar 13, and includes a compression spring. The compression spring is installed between the female connector component 15 and the sliding collar 13, and the movement path of the female connector component 15 and the sliding collar 13 is restricted by the limiting fastener.

[0036] The snap-fit ​​assembly is fixedly mounted on the sliding collar 13 and includes a positioning block 19, a snap-fit ​​16, and a snap-fit ​​fastener 21. The positioning block 19 is fixedly mounted on the female connector assembly 15, and the snap-fit ​​16 is mounted on the positioning block 19 via the snap-fit ​​fastener 21. The snap-fit ​​16 can rotate around the axis of the snap-fit ​​fastener 21. Magnets 20 that attract each other are respectively provided on the positioning block 19 and the snap-fit ​​fastener 21.

The long wedge block 18 is located on the side of the latch 16 closer to the female connector assembly 15, and the short wedge block 17 is located on the side of the latch 16 away from the female connector assembly 15.

[0038] When the fixed rotary evaporator 1 and the connecting rotary evaporator 4 need to be coaxially connected, the operator holds the connecting component 3 and moves the connecting rotary evaporator 4 towards the fixed rotary evaporator 1 along its axial direction. When the male end of the fixed rotary evaporator 1 and the conical surface of the female end of the connecting rotary evaporator 4 come into contact, the connecting component 3 continues to move towards the fixed rotary evaporator 1 along its axial direction until the short wedge block 17 of the latch 16 passes past the fixed component 2 and stops moving. At this point, the fixed component 2 and the connecting component 3 form a tight connection, realizing the locking function of the fixed rotary evaporator 1 and the connecting rotary evaporator 4.

[0039] When disconnection is required, after the automated synthesis rotary evaporator is rotated to any angle, the connecting assembly 3 is grasped, causing the connecting rotary evaporator 4 to move in the opposite direction to the fixed rotary evaporator 1 along its axis. When the long wedge block 18 of the latch 16 passes the fixed assembly 2, the connecting assembly 3 causes the connecting rotary evaporator 4 to move in the opposite direction to the fixed rotary evaporator 1 along its axis, thus disconnecting the connecting rotary evaporator 4 from the fixed rotary evaporator 1.

[0040] In summary, by utilizing the aforementioned technical solution of this utility model, through the coordinated operation of the fixing and connecting components, and the design of the special wedge-shaped block and limiting component in the snap-fit ​​assembly, rapid locking and separation between rotary evaporators can be achieved, ensuring the coaxiality and airtightness of the connection. This significantly improves operational convenience, enhances equipment operational stability, and reduces experimental risks. Furthermore, the use of structures such as magnetic automatic correction further simplifies the operation process, enabling the device to exhibit higher reliability and efficiency in automated synthesis applications.
