Description

Technical Field

[0001] The invention relates to the technical field of water bath pots, in particular to a portable adjustable constant temperature water bath pot for synthesizing pharmaceutical intermediates. Background Art

[0002] A water bath is a common laboratory device used to heat, dissolve, react, distill, concentrate, or dry samples at a constant temperature. It works by heating the water in the container, leveraging the water's constant temperature properties to provide a stable temperature environment for the sample.

[0003] After searching, it was found that according to the announcement number CN210935042U, a constant temperature water bath is disclosed. The key points of its technical solution are that it includes a box body with an upward box opening, a cover plate for shielding the box opening is provided on the box body, an opening is provided on the cover plate and an end cover for shielding the opening is provided, and a storage box is provided on the box body, and a box cover for shielding the box opening is detachably connected to the storage box; this constant temperature water bath can store the removed end cover, so that the end cover is not easily lost. However, when actually used, this solution still has the following shortcomings:

[0004] In the existing water bath related technical design, the end cover is an important component of the water bath, and its structure is often composed of multiple rings of different sizes assembled and spliced ​​together, in order to meet the placement requirements of beakers of different specifications in the water bath and expand its scope of application. However, in actual use, when it is necessary to adapt to beakers of different sizes, the user needs to frequently disassemble and reassemble the ring on the end cover. Each time the beaker size is changed, it takes a certain amount of time. This process is not only cumbersome and time-consuming, but the frequent disassembly and assembly may also cause the ring connection to become loose and worn, affecting the overall stability and sealing of the end cover.

[0038] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 , a portable adjustable constant temperature water bath for synthesizing pharmaceutical intermediates, comprising a housing unit and a placement unit;

[0039] The housing unit includes a pot body 11, a cover plate 12 is provided at the opening of the pot body 11, two clamping plates 13 are symmetrically fixedly installed at both ends of the cover plate 12, a clamping groove 14 adapted to the clamping plate 13 is provided on the top surface of the pot body 11, and four placement openings 15 are provided on the top surface of the cover plate 12;

[0040] The placement unit includes fixed sleeves 21 fixedly mounted on the bottom surface of the cover plate 12 at the sides of the four placement openings 15.

[0042] When the cover 12 is in the stowed state, the component on the top surface of the cover 12 can be located on the inner side of the pot body 11 to reduce the volume for carrying. When the cover 12 is in use, the cover 12 can be turned over and fixed by the clamping plate 13 and the clamping groove 14. When the rotating ring plate 22 rotates, since the spring telescopic rod 25 is slidably connected with the guide sleeve 24 and is slidably connected with the arc-shaped opening 23 through the guide rod 27, the position of the spring telescopic rod 25 can be adjusted when the rotating ring plate 22 drives the arc-shaped opening 23 to rotate, so that the spring telescopic rod 25 extends out of the guide sleeve 24 and contacts the outer wall of the beaker through the push plate 26. After the push plate 26 contacts the outer wall of the beaker, the spring telescopic rod 25 can be shortened to ensure that the position of the push plate 26 is fixed. When the push plate 26 moves, the folded ring cloth 28 can be stretched to seal the gap between the beaker and the placement opening 15 for efficient heating.

[0043] Reference Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 The two mounting sleeves 31 are provided with a sealing assembly, and the sealing assembly includes a lifting rod 32 that is slidably mounted on the inner walls of the two mounting sleeves 31. The top of the two lifting rods 32 is fixedly mounted with a mounting frame 33. The mounting frame 33 is U-shaped, and the sealing plate 35 is rotatably mounted on the inner wall of the mounting frame 33 through a rotating shaft. A supporting spring 34 is set on the lifting rod 32, and the two ends of the supporting spring 34 are fixedly connected to the mounting frame 33 and the mounting sleeve 31. A lap plate 36 is fixedly mounted on the end of the sealing plate 35 away from the rotating shaft. The inner wall of the mounting frame 33 is provided with a lap groove corresponding to the lap plate 36. Two plug rods 37 corresponding to the lap plate 36 are symmetrically arranged on the side of the mounting frame 33. A return spring 38 is set on the plug rod 37, and the two ends of the return spring 38 are fixedly connected to the plug rod 37 and the mounting frame 33 respectively.

[0044] The linkage structure includes a driven bevel gear 41 rotatably mounted on the outer wall of the fixed sleeve 21 via a rotating rod, a transmission gear 42 fixedly mounted on the end of the rotating rod, a driving rack 43 fixedly mounted on the bottom end of the lifting rod 32 and meshing with the transmission gear 42, and a driven bevel gear ring 44 fixedly sleeved on the outer wall of the rotating ring plate 22 and meshing with the driven bevel gear 41, with a limiting mechanism provided on the driven bevel gear ring 44;

[0045] The staff can place the beaker in the placement opening 15 on the cover plate 12. After placement, pull the two insertion rods 37 to move the insertion rods 37 out of the overlapping grooves, and then rotate the closing plate 35 so that the overlapping plates 36 on the side of the closing plate 35 enter the overlapping grooves, and then release the insertion rods 37. Under the action of the reset spring 38, the insertion rods 37 can slide in the opposite direction to limit the overlapping plates 36 in the overlapping grooves, and the closing plate 35 can be in a horizontal state. At this time, the installation frame 33 can be pressed downward. The lifting rod 32 is driven to slide downward along the mounting sleeve 31. During the sliding process of the lifting rod 32, the driving rack 43 can be synchronously driven to move. The driving rack 43 is engaged with the transmission gear 42, and then the transmission gear 42 and the driven bevel gear 41 are driven to rotate. The driven bevel gear 41 is engaged with the driven bevel gear ring 44 on the outer wall of the rotating ring plate 22, and then the rotating ring plate 22 is driven to rotate. When the bottom surface of the sealing plate 35 is in contact with the opening of the beaker, the pressing of the sealing plate 35 can be stopped.

[0046] Reference Figure 7 The limiting mechanism includes a shaft 45 rotatably mounted on the bottom surface of the cover plate 12, and the top end of the shaft 45 passes through the top surface of the cover plate 12, a pawl 46 is fixedly mounted on the bottom end of the shaft 45, and a ratchet ring 47 engaged with the pawl 46 is fixedly sleeved on the outer wall of the driven bevel gear ring 44, and a torsion spring 48 is sleeved on the shaft 45, and the two ends of the torsion spring 48 are fixedly connected to the shaft 45 and the cover plate 12 respectively;

[0047] The lifting rod 32 can move upward under the action of the supporting spring 34, thereby driving the rotating ring plate 22 to reverse and resetting the push plate 26. Then, the sealing plate 35 can be opened to the vertical state, and the beaker after heating is completed can be quickly taken out.

[0048] Reference Figure 8-11The inner bottom surface of the pot body 11 is provided with four sets of lifting components corresponding to the placement opening 15. The lifting components include two support rods 51 fixedly mounted on the inner bottom surface of the pot body 11, and a lifting frame 52 is slidably mounted on the two support rods 51. A second support spring 53 is fixedly mounted on the top surface of the lifting frame 52, and a pressure plate 54 is fixedly mounted on the top of the second support spring 53. A third support spring 55 is fixedly mounted between the bottom surface of the lifting frame 52 and the inner bottom surface of the pot body 11. A sliding frame 56 is fixedly mounted on the side of the lifting frame 52. A guide groove 57 corresponding to the sliding frame 56 is opened on the inner wall of the pot body 11, and a locking structure is provided on the inner side of the lifting frame 52;

[0049] The locking structure includes an inner cavity 61 symmetrically opened on the inner side of the lifting frame 52 and connected to the sliding frame 56. A transmission plate 62 is slidably installed on the inner wall of the inner cavity 61. A transmission port 63 is opened at one end of the transmission plate 62 away from the sliding frame 56. A pressure frame 64 adapted to the transmission port 63 is provided on the top surface of the lifting frame 52. The sides opposite to the transmission port 63 and the pressure frame 64 are both arranged as inclined surfaces, and the top surface of the pressure frame 64 is fixedly connected to the bottom surface of the pressure plate 54. A supporting spring 65 is fixedly installed between one end of the two transmission plates 62 located on the inner side of the sliding frame 56 and the side surface of the lifting frame 52. A limit plate 66 is provided on both side surfaces of the sliding frame 56. A top plate 67 adapted to the limit plate 66 is fixedly installed on the ends of the two transmission plates 62. The cross-sectional shape of the top plate 67 is an isosceles trapezoid.

[0050] The staff can adjust the height of the lifting frame 52 according to the height of the beaker to be used. When adjusting, the pressure plate 54 can be pressed downward. When the pressure plate 54 moves downward, it can be transmitted through the transmission port 63 on the transmission plate 62 on the inclined surface of the pressure frame 64, so that the transmission plate 62 can slide along the inner cavity 61. The transmission plate 62 can slide in the direction away from the sliding frame 56 and compress the support spring 4 65. When the transmission plate 62 slides, it can synchronously drive the top plate 67 to slide, so that the top plate 67 is separated from the limit plate 66 on the side of the sliding frame 56. The limit plate 66 loses its support and loses the top force with the inner wall of the guide groove 57. At this time, the pressure plate 54 can be kept pressed down and the lifting and lowering can be driven. The frame 52 slides up and down along the guide groove 57 through the sliding frame 56 to adjust the height of the lifting frame 52 so as to adapt to beakers of different heights for use. After the adjustment is completed, the lifting frame 52 can be fixed and the pressure plate 54 can be loosened. When the pressure plate 54 is loosened, the pressure plate 54 can move upward relative to the lifting frame 52 under the elastic force of the support spring 2 53 and drive the pressure frame 64 to move. When the pressure frame 64 moves, the transmission plate 62 can slide in the opposite direction under the action of the support spring 4 65 and drive the top plate 67 to support the limit plate 66, so that the limit plate 66 is pressed against the inner wall of the guide groove 57, thereby realizing the limitation of the sliding frame 56 and the lifting frame 52, ensuring that the lifting frame 52 can be used stably.

[0051] The specific working principle of the present invention is as follows:

[0052] When in use, in the stored state, the cover plate 12 is in an inverted state, and the mounting frame 33 and the like are located on the inner side of the pot body 11 so as to reduce the volume for carrying. In the in-use state, the cover plate 12 can be turned over and fixed by the card plate 13 and the card slot 14. At the same time, the sealing plate 35 is in a vertical state, exposing the mounting frame 33. At this time, the staff can adjust the height of the lifting frame 52 according to the height of the beaker to be used. When adjusting, the pressure plate 54 can be pressed downward. When the pressure plate 54 moves downward, it can be driven by the inclined surface of the pressure frame 64 to transmit the transmission port 63 on the transmission plate 62, so that the transmission plate 62 can slide along the inner cavity 61. The transmission plate 62 can slide in the direction away from the sliding frame 56 and compress the support spring 465. When the transmission plate 62 slides, it can synchronously drive the top plate 67 to slide, so that the top plate 67 and the side of the sliding frame 56 When the lifting frame 52 is lifted, the lifting plate 52 is lifted and the lifting frame 52 is lifted and the lifting frame 52 is lifted. When the lifting frame 52 is lifted, the lifting plate 52 is lifted and the lifting frame 52 is lifted. When the lifting frame 52 is lifted, the lifting plate 52 is lifted and the lifting frame 52 is lifted. When the lifting frame 52 is lifted, the lifting plate 54 is lifted and the lifting frame 52 is lifted. When the lifting frame 52 is lifted, the lifting plate 54 is lifted and the lifting frame 52 is lifted. When the lifting frame 64 moves, the transmission plate 62 can slide in the opposite direction under the action of the support spring 4 65 and drive the top plate 67 to support the limiting plate 66, so that the limiting plate 66 is pressed tightly against the inner wall of the guide groove 57, thereby limiting the sliding frame 56 and the lifting frame 52, ensuring that the lifting frame 52 can be used stably.

[0053] The staff can then place the beaker in the placement port 15 on the cover plate 12, and the bottom surface of the beaker contacts the top surface of the lifting frame 52. After placement is completed, the two plug rods 37 are pulled to move the plug rods 37 out of the overlapping grooves, and the closing plate 35 is rotated to make the overlapping plates 36 on the side of the closing plate 35 enter the overlapping grooves, and the plug rods 37 can be loosened. Under the action of the return spring 38, the plug rod 37 can slide in the opposite direction to limit the overlapping plates 36 in the overlapping grooves, and the closing plate 35 can be in a horizontal state. At this time, the mounting frame 33 can be pressed downward, and the lifting rod 32 can be driven to slide downward along the mounting sleeve 31. During the sliding process of the lifting rod 32, the driving rack 43 can be synchronously driven to move, and the driving rack 43 can be engaged with the transmission gear 42, thereby driving the transmission gear 42 and the driven bevel gear 41 to rotate, and the driven bevel gear 41 and the rotating The driven bevel gear ring 44 on the outer wall of the movable ring plate 22 is meshed, thereby driving the rotating ring plate 22 to rotate. Since the spring telescopic rod 25 is slidably connected to the guide sleeve 24 and is slidably connected to the arc-shaped opening 23 through the guide rod 27, the position of the spring telescopic rod 25 can be adjusted when the rotating ring plate 22 drives the arc-shaped opening 23 to rotate, so that the spring telescopic rod 25 extends out of the guide sleeve 24 and contacts the outer wall of the beaker through the push plate 26. As the lifting rod 32 continues to slide, the spring telescopic rod 25 can be shortened after the push plate 26 contacts the outer wall of the beaker to ensure that the position of the push plate 26 is fixed. When the push plate 26 moves, the folded ring cloth 28 can be stretched to block the gap between the beaker and the placement opening 15, so as to efficiently heat it. When the bottom surface of the sealing plate 35 is in contact with the opening of the beaker, the pressure on the sealing plate 35 can be stopped.

[0054] The locking state of the ratchet ring 47 and the pawl 46 is achieved, so that the position of the mounting frame 33 and the sealing plate 35 can be fixed, and the sealing plate 35 can block the opening of the beaker. After the pot body 11 is used, the staff can rotate the shaft 45 to drive the pawl 46 to rotate and separate from the ratchet ring 47, thereby releasing the limit of the ratchet ring 47. Under the action of the support spring 34, the lifting rod 32 can move upward, thereby driving the rotating ring plate 22 to reverse and reset the push plate 26. Then, the sealing plate 35 can be opened to the vertical state, and the beaker after heating can be quickly taken out.
