[0002] A cryogenic coolant circulation pump is a cryogenic liquid circulation device that uses mechanical refrigeration to provide cryogenic liquids and a cryogenic water bath. Combined with a rotary evaporator, vacuum freeze dryer, circulating water vacuum pump, magnetic stirrer, and other instruments, it can perform multifunctional low-temperature chemical reactions and drug storage.

[0003] Existing low-temperature coolant circulation pumps are often designed to be airtight. Failures such as unusual noises or loss of external circulation during operation require inspection, adjustment, and replacement of the internal structure, which requires opening the heat dissipation covers on both sides. To ensure a secure connection, the heat dissipation covers are often connected to the housing at the four corners using locking members. Disassembly requires specialized tools, making the process cumbersome and laborious. Therefore, we propose a low-temperature coolant circulation pump that is easily accessible to address these issues. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-6 As shown, a low-temperature coolant circulation pump that is easy to maintain includes a circulation pump body 1, side panels 2 are provided on the left and right sides of the circulation pump body 1, and half frames 3 are fixedly connected to the side panels 2. The half frames 3 are used to hide the heat dissipation cover 4 when it pops up; an opening and closing component, the opening and closing component includes a heat dissipation cover 4 provided on the side panels 2, and a protrusion 5 is fixedly connected to the four corners of one side of the heat dissipation cover 4. A connecting block 6 is fixedly connected to the top of one side of the protrusion 5. The connecting block 6 is used to facilitate connection with a spring 10. A roller 7 is rotatably connected to the side away from the protrusion 5. The roller 7 can be respectively matched with the vertical groove 8 and the horizontal groove 9 for guidance to reduce friction. The opening and closing component also includes a plate provided on the side panel 2. A vertical groove 8 is provided on one side, and a horizontal groove 9 connected to the vertical groove 8 is also provided on the side panel 2. The roller 7 is located in the adjacent horizontal groove 9. The left and right sides of the top inner wall of the half frame 3 are fixedly connected with springs 10 respectively. The spring 10 is used to automatically move upward under the action of elastic force when the heat dissipation cover 4 is released, so that the inside of the circulating pump can be opened and the maintenance operation is convenient. The bottom end of the spring 10 is fixedly connected to the top of the adjacent connecting block 6 respectively. The opening and closing assembly also includes an arc groove 11 on the upper and lower sides of one side of the side panel 2. A sealing plate 12 is rotatably connected in the arc groove 11, and a ring handle 13 is fixedly connected to the sealing plate 12. The ring handle 13 can be used to easily twist the sealing plate 12 to rotate in the arc groove 11.

[0023] The upper and lower sides of one side of the heat dissipation cover 4 are provided with inferior arc grooves that are compatible with the arc groove 11. The front and back sides of the heat dissipation cover 4 are provided with rounded corners. The inferior arc groove can facilitate locking the heat dissipation cover 4 when the sealing plate 12 is rotated to this side, so that the heat dissipation cover 4 is more stable when closed.

[0024] The outer diameter of the sealing plate 12 is adapted to the inner diameter of the arc groove 11. The sealing plate 12 is rotatably connected to the arc groove 11 via a damping shaft. By providing the damping shaft, the rotation damping can be increased, thereby preventing the sealing plate 12 from rotating automatically and improving the reliability of the device.

[0025] The area of ​​the shielding portion on the half frame 3 is larger than the area of ​​the heat dissipation cover 4. Limiting the area of ​​the shielding portion can ensure that the heat dissipation cover 4 will be completely shielded by the half frame 3 when it pops up, making it easy to hide the heat dissipation cover 4 so that it will not interfere with the operation of maintenance personnel.

[0026] The connection between the transverse groove 9 and the vertical groove 8 is provided with a rounded corner, which can facilitate the smooth passage of the roller 7 and avoid obstruction.

[0027] During the specific implementation of the present invention: when it is necessary to inspect and repair the inside of the circulating pump, the ring handles 13 on the upper and lower sides are pulled in succession on one side of the side panel 2 that needs to be opened to drive the sealing plate 12 to rotate so that it no longer blocks the surface of the heat dissipation cover 4, and then the heat dissipation cover 4 is lightly lifted outward to make the rollers 7 roll out of the corresponding horizontal grooves 9 and into the vertical grooves 8, and then the elastic force of the spring 10 pulls the rollers 7 to roll upward in the vertical grooves 8, driving the heat dissipation cover 4 to move upward as a whole until it is completely immersed in the half frame 3. At this time, the side of the side panel 2 is completely opened, which is convenient for maintenance personnel to inspect and operate.
