Technical Field

[0001] The invention relates to the technical field of cell culture devices, in particular to a high-pressure cell culture chamber with quick opening and closing functions. Background Art

[0002] This unit and the university have previously jointly designed a high-pressure cell culture chamber and applied for a patent, with the application number 2018115822134. The fixing structure of the door and the cabin of the high-pressure cell culture chamber is: bolt bayonet holes are respectively set on the extended fixed corners of the four corners of the door, and bolt seats are respectively set at the four corner positions of the door frame of the cabin body corresponding to the door. The bolt seat is centrally connected to the bolt, and the movable end of the bolt is inserted into the bolt bayonet and locked by the nut, so that the door is sealed and fastened outside the door frame of the cabin body. When the door needs to be closed, this fixing structure requires the movable ends of the four bolts to be respectively inserted into the corresponding bolt bayonet holes, and then the nuts on the four bolts are locked to close the door. When the door needs to be opened, this fixing structure requires the bolts at the four corner positions to be loosened one by one, and then the movable ends of the four bolts are respectively pulled out from their corresponding bolt bayonet holes to open the door. The operation of closing and opening the door is relatively troublesome. The designer of the present invention has designed a quick opening and closing structure so that the door can be opened and closed quickly. Summary of the invention

A rotating rod 9 is passed through the top of the U-shaped movable frame 8, and a forward screw thread is provided on the left portion of the rotating rod 9 and a reverse screw thread is provided on the right portion (although not shown in the figure, the forward screw thread and the reverse screw thread are existing components, and how the forward screw thread and the reverse screw thread are fixed on the rod is an existing technology). The top of the left inverted U-shaped movable frame 7 is located on the forward screw thread, and the top of the right inverted U-shaped movable frame 8 is located on the reverse screw thread. The rotating rod 9 is covered with a blind plate cover 10, and the left side of the blind plate cover 10 is sleeved on the left side of the rotating rod 9, and the right side of the blind plate cover 10 is sleeved on the right side of the rotating rod 9, and the forward screw thread and the reverse screw thread are placed in the blind plate cover 10.

[0014] Two fixed bases 21 are fixed at intervals at the middle position on the right side of the fixed ring frame 2 and close to the position of the three-petal clamp 4, a vertical fixed rod 11 is fixed between the two fixed bases 21, the upper and lower parts of the vertical fixed rod 11 are respectively sleeved with rotating shafts 12, the two rotating shafts 12 are fixedly connected to the elliptical hatch 14 through a connecting block 13, a fixed column 15 is fixed to the top of the hatch 14, a fixed limit ring 16 is sleeved on the fixed column 15, the fixed column 15 and the limit ring 16 are integrally formed, a moving block 17 is sleeved on the fixed column 15, the moving block 17 is limited between the limit ring 16 and the top of the hatch 14, a waist-shaped hole 18 is opened on the moving block 17 so that the moving block 17 can move slightly forward and backward on the fixed column 15, a limiting block 19 is fixed to the front end of the moving block 17, and a long hole 20 is opened on the limiting block 19.

[0015] A sliding cell culture tray 22 is arranged in the cabin 1 along the length direction. The cell culture tray 22 is hollow. For example, the opposite side walls in the cabin 1 are provided with slide grooves along the length direction. Slide blocks matching the slide grooves are provided on both sides of the cell culture tray 22, so that the cell culture tray 22 can slide along the corresponding slide grooves, making it convenient for the cell culture tray 22 to be taken out of the cabin 1 or put into the cabin 1.

[0016] A sliding collection tray 23 is provided inside the cabin 1 along the length direction and below the cell culture tray 22. The collection tray 23 is used to collect debris generated by the cell culture above. For example, slide grooves are provided along the length direction on the opposite side walls of the cabin 1, and sliding blocks matching the slide grooves are provided on both sides of the collection tray 23, so that the collection tray 23 can slide along the corresponding slide grooves, making it convenient for the collection tray 23 to be taken out of the cabin 1 or put into the cabin 1.

[0017] The hatch door 14 is pushed toward the hatch 3, the rotating shaft 12 rotates, the hatch door 14 is closed, the opening of the hatch door 14 is docked with the hatch 3, the opening of the hatch door 14 is accommodated in the three-petal clamp 4, and the rotating rod 9 is rotated. Driven by the forward screw thread and the reverse screw thread, the first petal and the second petal of the three-petal clamp 4 move relatively close to each other to achieve the three-petal clamp 4 clamping the hatch door 14, and the moving block 17 is slightly moved forward. The left limit rod 5 and the right limit rod 6 pass through the long hole 20 of the limit block 19, and the left limit rod 5 is just limited to the left end of the long hole 20 of the limit block, and the right limit rod 6 is just limited to the right end of the long hole 20 of the limit block, thereby realizing the rapid closing of the hatch door 14.

[0018] The moving block 17 is slightly moved backward, and the left limit rod 5 and the right limit rod 6 do not pass through the long hole 20 of the limit block 19. The rotating rod 9 is rotated in the opposite direction. Driven by the forward screw thread and the reverse screw thread, the first petal and the second petal of the three-petal clamp 4 move away from each other, pushing the hatch 14 away from the hatch 3, and the rotating shaft 12 rotates to open the hatch 14, thereby realizing the rapid opening of the hatch 14.

[0019] In this solution, the shape of the left limit rod 5 matches the shape of the left end of the elongated hole 20 of the limit block 19, and the shape of the right limit rod 6 matches the shape of the right end of the elongated hole 20 of the limit block 19, so that the left limit rod 5 and the right limit rod 6 can achieve better limiting with the left and right ends of the elongated hole 20 of the limit block 19.

[0020] In this solution, the three-petal clamp 4 is clamped to the cabin door 14 by rotating the rotating rod 9. Since the left limit rod 5 and the right limit rod 6 on the three-petal clamp 4 are limited in the long hole 20 of the limit block 19, even if the high pressure in the cabin body 1 impacts the three-petal clamp 4, the three-petal clamp 4 under the limiting action will not loosen to the left or right, and can always tightly hold the cabin door 14, so that the cabin door can be tightly locked.

[0021] In this solution, when the hatch 1 needs to be closed, it is only necessary to rotate the rotating rod 9 so that the three-petal clamp 4 clamps the hatch 14, and then slightly move the moving block 17 forward so that the left limit rod 5 and the right limit rod 6 on the three-petal clamp 4 are limited in the long hole 20 of the limit block 19, so that the hatch 14 can be quickly closed. When the hatch 1 needs to be opened, it is only necessary to slightly move the moving block 17 backward so that the left limit rod 5 and the right limit rod 6 are not in the long hole 20 of the limit block 19, and rotate the rotating rod 9 in the opposite direction so that the three-petal clamp 4 releases the hatch 14. The operation is relatively simple, and the hatch can be quickly opened and closed.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
