[0031] Reference Figure 1 As shown, the present invention provides a technical solution: a biological cell culture device, comprising an incubator 1, a control panel 2 mounted on the surface of the incubator 1, an incubation chamber 3 disposed on the surface of the incubator 1, a door 4 mounted on the surface of the incubation chamber 3, and a limiting structure 5 disposed on the inner wall of the incubation chamber 3. The limiting structure 5 facilitates pulling a storage plate 503 out of the incubation chamber 3, thereby avoiding the need to extend an arm into the incubation chamber 3 when placing a biological cell sample. This facilitates placing the biological cell sample into the incubation chamber 3, avoids the situation where an arm introduces contaminants into the incubation chamber 3, and thereby ensures the culture purity and test results of the cell sample. A protective structure 6 is disposed on the surface of the incubator 1. By disposing the protective structure 6, a locking block 64 limits the position of the door 4, thereby preventing the door 4 from closing due to accidental contact when placing or removing the biological cell sample, and thereby preventing the biological cell sample from falling and being damaged due to the door 4 closing and colliding with the storage plate 503.
[0032] The specific settings and functions of the limiting structure 5 and the protective structure 6 are described in detail below.
[0033] Reference Figure 2 - Figure 5As shown, in this embodiment: the limiting structure 5 includes two U-shaped frames 501, and the two U-shaped frames 501 are fixedly connected to the inner wall of the cultivation chamber 3. The inner wall of the U-shaped frame 501 is provided with two rectangular grooves 502, and the inner wall of the U-shaped frame 501 is slidably inserted with a storage plate 503, and one side of the storage plate 503 is fixedly connected to two rectangular tubes 504, and the inner wall of the rectangular tube 504 is fixedly connected with a first spring 505, and the inner wall of the rectangular tube 504 is slidably inserted with an insertion rod 506, and the other end of the first spring 505 is fixedly connected to the insertion rod 506, and a traction rope 507 is slidably passed through the surface of the rectangular tube 504, one end of the traction rope 507 is fixedly connected to the insertion rod 506, and the other end of the traction rope 507 passes through the storage plate 503, and the ends of the two traction ropes 507 close to each other are fixedly connected to the rectangular plate 508. The inner wall of the U-shaped frame 501 is fixedly connected to a plurality of fixed rods 509. The arc surface of the fixed rods 509 is covered with a cylinder 510. When the storage plate 503 moves, it will slide along the surface of the cylinder 510. The cylinder 510 rotates on the surface of the fixed rods 509 with the force of the storage plate 503 moving. The cylinder 510 reduces the friction of the storage plate 503 when moving within the U-shaped frame 501, thereby facilitating the movement of the storage plate 503. A limiting groove 511 is defined on one side of the insertion rod 506. The inner wall of the limiting groove 511 is slidably connected to a limiting arm 512. The limiting arm 512 is fixedly connected to the surface of the rectangular tube 504. The movement of the insertion rod 506 drives the limiting arm 512 to slide along the inner wall of the limiting groove 511. The limiting arm 512 limits the movement path of the insertion rod 506, thereby preventing the insertion rod 506 from falling out of the rectangular tube 504. There are two limit rods 513 sliding through the surface of the rectangular plate 508. Both limit rods 513 are fixedly connected to the surface of the storage plate 503. When the rectangular plate 508 moves, it will slide along the surface of the limit rods 513. The limit rods 513 limit the moving path of the rectangular plate 508, thereby preventing the rectangular plate 508 from offsetting during movement.
[0034] Reference Figure 6 and Figure 7As shown, specifically, the protective structure 6 includes an extension plate 61, which is fixedly connected to the surface of the incubator 1. A round rod 62 slides through the surface of the extension plate 61. The arc surface of the round rod 62 is covered with a second spring 63. The two ends of the second spring 63 are respectively fixedly connected to the round rod 62 and the extension plate 61. The end of the round rod 62 near the box door 4 is fixedly connected to a clamping block 64. The surface of the box door 4 has a clamping slot 65, and the size of the clamping slot 65 is adapted to the size of the clamping block 64. One end of the clamping block 64 is fixedly connected to a protrusion 67 with a trapezoidal cross-section. The clamping block 64 drives the protrusion 67 to be inserted into the clamping slot 65, and the protrusion 67 facilitates the insertion of the clamping block 64 into the clamping slot 65. A rectangular rod 66 slides on the surface of the extension plate 61, and the rectangular rod 66 is fixedly connected to the surface of the block 64. When the block 64 moves, it drives the rectangular rod 66 to slide in the extension plate 61. The rectangular rod 66 limits the moving path of the block 64, thereby preventing the block 64 from rotating when moving.
[0035] When the lever 506 is in the upright position, the lever 506 is pulled back to move and the lever 506 is moved back to the upright position. The rod 506 is released from the rectangular tube 504. At this time, the first spring 505 is in a compressed state, and then the placement plate 503 is pulled. The placement plate 503 moves and slides along the inner wall of the U-shaped frame 501. The placement plate 503 also slides along the surface of the cylinder 510 when moving. The cylinder 510 rotates on the surface of the fixed rod 509 with the help of the force of the movement of the placement plate 503. The cylinder 510 reduces the friction of the placement plate 503 when moving in the U-shaped frame 501, thereby facilitating the movement of the placement plate 503. When the placement plate 503 moves to the appropriate position, the placement plate 503 is located outside the incubation chamber 3. Then, the biological cell sample to be incubated is placed on the surface of the placement plate 503, and the placement plate 503 is pushed back. After the placement plate 503 is released, the insertion rod 506 is inserted into the rectangular groove 502 with the help of the extension force of the first spring 505, thereby limiting the placement plate 503 in the U-shaped frame 501.
[0036] When the door 4 needs to be opened, the round rod 62 is first pulled. The round rod 62 moves and slides in the extension plate 61. The movement of the round rod 62 causes the second spring 63 to be stretched. When the round rod 62 moves, it drives the block 64 to move. When the block 64 moves, it drives the rectangular rod 66 to slide in the extension plate 61. The rectangular rod 66 reaches the moving path of the block 64 to limit the movement of the block 64, thereby preventing the block 64 from rotating when moving. When the block 64 moves to the appropriate position, the door 4 is opened. When the door 4 is rotated to the appropriate position, the round rod 62 is released. The round rod 62 will drive the block 64 to move with the help of the contraction force of the first spring 505. The movement of the block 64 will drive the protrusion 67 to move. When the block 64 moves to the appropriate position, the block 64 will drive the protrusion 67 to insert into the slot 65. The block 64 reaches the position of restricting the door 4, thereby preventing the door 4 from closing due to accidental collision when taking and placing biological cell samples. The protrusion 67 facilitates the insertion of the block 64 into the slot 65.
