[0025] Specifically, the support frame group includes a support rod 101 connected with the support 10, a first support ring 111 connected with the support rod 101, a connecting rod 102 connected with the first support ring 111, and a second support ring 112 connected with the connecting rod 102, and the first support ring 111, the connecting rod 102 and the second support ring 112 form a tapered structure with a wide upper part and a narrow lower part.

[0026] The first support ring 111 and the second support ring 112 are provided with openings 110 on the same side, and the two openings 110 are communicated to form a gap channel 13 for the mouth of the evaporation bottle to move.

[0027] The first support ring 111, the connecting rod 102 and the second support ring 112 are all sleeved with a plastic sleeve 15 made of PPS material.

[0028] The positioning mechanism includes a first limiting rod 21 fixedly connected with the support 10 and a second limiting rod 22 movably connected with the support 10, a first arc segment 210 extending outward horizontally is arranged on the first limiting rod 21, and a first notch 211 is arranged on the first limiting rod 21 at a position corresponding to the first arc segment 210; a connecting sleeve 23 sleeved on the support 10 is arranged on the second limiting rod 22, a locking bolt 24 is screwed on the connecting sleeve 23, and the screw end surface of the locking bolt 24 abuts against the outer wall of the support 10 to limit the rotation of the connecting sleeve 23 and the second limiting rod 22 in the horizontal direction.

[0029] A second arc segment 220 extending outward horizontally is arranged on the second limiting rod 22, and a second notch 221 is arranged on the second limiting rod 22 at a position corresponding to the second arc segment 220; sponge sleeves 25 are arranged on the first arc segment 210 and the second arc segment 220.

[0030] The support mechanism includes a support rod 161 hinged to the groove wall on one side of the guide groove 16, a support plate 162 connected to the non-hinged end of the support rod 161, the support plate 162 being located inside the guide groove 16; and an anti-slip pad 163 provided on the upper surface of the support plate 162.

[0031] The working principle of this utility model is as follows:

[0032] like Figures 1 to 4 As shown, the bottom of the placement groove 12 is provided with a groove 120 corresponding to the position of the support frame assembly. A measuring cup is placed in the groove 120. The groove wall of the groove 120 limits the measuring cup and prevents it from shifting during placement or receiving. After the evaporation flask is removed from the rotary evaporator, it is placed on the support frame assembly with the bottle mouth facing upward. The second support ring 112 directly abuts against the outer wall of the bottom of the evaporation flask. Plastic sleeves 15 are fitted on the first support ring 111, the connecting rod 102 and the second support ring 112 to reduce contact wear on the bottle body. At the same time, the asbestos mesh 14 fits against the bottle body to keep it warm and prevent the evaporation flask from being damaged by sudden cooling. The neck of the bottle abuts against the first arc segment 210 through the first notch 211 to achieve initial placement limitation.

[0033] In use, connect the switch valve (not marked) to the bottle opening to prevent the solution from flowing out during inversion and to facilitate control of the amount of solution dispensed. Then, push the bottle opening to invert the bottle. The clearance channel 13 formed by the opening 110 on the same side of the first support ring 111 and the second support ring 112 rotates clockwise until the bottle opening is in a vertical downward position. At this point, open the switch valve to dispense the material as needed. After each dispensing, simply remove the measuring cup from the groove 120. To avoid interference with the position of the switch valve, remove it horizontally along the axial direction of the placement groove 12. This allows for multiple dispensing operations and reduces the workload of the operator.

[0034] After the material is inspected, push the bottle mouth counterclockwise, and move it through the clearance channel 13 until the bottle neck is against the first arc segment 210. To prevent the evaporator from flipping outward under force, loosen the locking bolt 24, rotate the connecting sleeve 23, and simultaneously drive the second limit rod 22 to rotate horizontally toward the bottle neck until the bottle neck is against the second arc segment 220 through the second notch 221. Then tighten the locking bolt 24 to achieve the positioning of the evaporator.

[0035] The connecting sleeve 23 is not fixed in the vertical direction of the support 10, thereby facilitating the combination of different specifications of the length of the neck of the evaporating bottle and the fixing position of the first limiting rod 21 to limit the evaporating bottle; in addition, when the neck of the evaporating bottle is short and cannot contact the first limiting rod 21, that is, cannot be placed in the position of the first arc segment 210, in order to avoid the overturning of the evaporating bottle in the non-force condition, the second limiting rod 22 should be moved to a position non-parallel to the first limiting rod 21, and the neck of the evaporating bottle is placed in the second arc segment 220, at this time, the evaporating bottle is in an inclined state as a whole and under the action of the gravity of the solution in the bottle, the stability of the placement position is ensured.

[0036] During the whole rotation process, the asbestos net 14 always keeps a contact state with the spherical bottle body of the evaporating bottle, on the one hand, plays an auxiliary supporting role, and on the other hand, can ensure the stability of the rotation, in combination with the soft texture of the asbestos net 14, the yielding deformation of the resistance to the bottle body lower part can also adapt to the placement of evaporating bottles of multiple specifications; at the same time, the sponge sleeve 25 is arranged on the first arc segment 210 and the second arc segment 220, which can reduce the abutting wear of the evaporating bottle.

[0037] In addition to the foregoing use process, when the density of the solution needs to be detected under other temperature conditions, it is more cumbersome to place the evaporating bottle on the rotary evaporator again, and at the same time, the heating period is also relatively long; therefore, the support rod 161 hinged on the groove wall on one side of the guide groove 16 needs to be rotated, the support plate 162 is synchronously driven to be horizontally rotated to the upper position of the recess 120, the heating source is placed on the support plate 162 through the guide groove 16, the anti-slip pad 163 can prevent the heating source from slipping, so as to avoid affecting the uniform heating effect, the heating source is arranged as an alcohol lamp, the on-off valve is removed, the alcohol lamp is ignited, the glass rod is inserted into the bottle body, and the solution is heated and stirred at the same time, so as to uniformly heat the solution, and the thermometer is used to probe into the bottle mouth at intervals during the heating process, so as to obtain the heating temperature; during the whole process, the first arc segment 210 and the second arc segment 220 keep abutting and limiting with the position of the neck.

[0038] When the temperature reaches the detection requirement, the locking bolt 24 is loosened first, the second limiting rod 22 is moved away, the alcohol lamp is extinguished, the alcohol lamp is taken out from the guide groove 16, the support rod 161 is moved back, the support plate 162 is synchronously driven to move away from the upper position of the recess 120, the measuring cup is placed in the recess 120, the on-off valve is connected to the bottle mouth, the bottle body is turned over according to the foregoing operation steps, and the on-off valve is opened to take the material in time.

[0039] During the whole heating process, the asbestos net 14 plays a good role in flame retardation and dispersion of heat, and its heat preservation also helps the uniform heating of the solution, the plastic sleeve 15 made of PPS material is also high-temperature resistant and plays a role in flame retardation, which together ensures the safety in use.
