Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a cell culture freezing box includes a culture box 1, a refrigerator 2 fixedly installed on the bottom of the inner wall of the culture box 1, a cover plate 3 rotatably installed on the top of the culture box 1, a handle 4 fixedly installed on the top of the cover plate 3, a culture dish 5 slidably installed on the inner wall of the culture box 1, a lock hole opened on the surface of the cover plate 3, and a self-locking device and a protective device provided on the surface of the culture box 1.

[0026] The self-locking device includes: a hollow box 6, a base plate 7, a locking tongue 8, two triangular blocks 10, and an unlocking rod 11. The hollow box 6 is fixedly installed on the surface of the culture box 1, the base plate 7 is fixedly installed on the side of the hollow box 6 away from the culture box 1, the locking tongue 8 slides through the inner and outer walls of the hollow box 6 and the culture box 1, the two triangular blocks 10 are fixedly installed at both ends of the locking tongue 8, and the unlocking rod 11 slides through the inner and outer walls of the hollow box 6.

[0027] A first spring 9 is provided between the locking tongue 8 and the base plate 7, and the unlocking rod 11 contacts the triangular block 10.

[0028] The side of the unlocking lever 11 that contacts the triangular block 10 is set as an arc surface, and a reset spring is provided between the unlocking lever 11 and the hollow box 6.

[0029] Working principle: After placement inside the culture box 1, rotate the cover plate 3 to the bottom. The rotation of the cover plate 3 contacts the locking tongue 8 and drives the locking tongue 8 to move into the hollow box 6. When the cover plate 3 has finished rotating, the first spring 9 resets and drives the locking tongue 8 to move towards the lock hole and lock into the lock hole. After placement, simply press the cover plate 3 to lock. Then, the entire device can be lifted out through the handle 4, which is convenient and quick and improves the portability of the device. Press the unlocking lever 11 to the bottom. The unlocking lever 11 moves and contacts the triangular block 10. The movement of the unlocking lever 11 drives the triangular block 10 to move towards the first spring 9. The movement of the triangular block 10 drives the locking tongue 8 to move away from the lock hole. After the locking tongue 8 moves, it no longer contacts the lock hole. Then, the cover plate 3 is reset by the torsion spring and rotates to the top. The operation is simple and improves work efficiency.

[0030] like Figure 1-5 As shown, the protective device includes: an air cylinder 121, a connecting rod 122, a transmission rod 123, a collar 124, a sealing plate 125, a transmission vertical rod 126, a transmission plate 128, and a baffle 129. The air cylinder 121 is fixedly installed on the bottom of the inner wall of the culture box 1. An air outlet is provided on the circumferential surface of the air cylinder 121. The connecting rod 122 is rotatably installed on the bottom of the cover plate 3. The transmission rod 123 is fixedly installed on the bottom of the connecting rod 122. The collar 124 is slidably installed on the circumferential surface of the air cylinder 121 and is fixedly connected to the transmission rod 123. The sealing plate 125 is slidably installed on the inner wall of the air cylinder 121. The transmission vertical rod 126 is fixedly installed between the sealing plate 125 and the culture dish 5. The transmission plate 128 is fixedly installed on the surface of the connecting rod 122. The baffle 129 is fixedly installed on the surface of the culture dish 5.

[0031] A second spring 127 is provided between the sealing plate 125 and the air cylinder 121, and the baffle 129 is in contact with the transmission plate 128.

[0032] A torsion spring is provided between the cover plate 3 and the culture box 1, and the collar 124 contacts the air outlet.

[0033] Working principle: The cover plate 3 rotates upwards, causing the connecting rod 122 to move upwards. The movement of the connecting rod 122 causes the transmission rod 123 to move upwards. The movement of the transmission rod 123 causes the collar 124 to move upwards. After the collar 124 moves, it is no longer in contact with the air outlet, allowing air to flow into the air cylinder 121 through the air outlet. Then, the second spring 127 resets, causing the sealing plate 125 to move upwards. The movement of the sealing plate 125 upwards causes the transmission vertical rod 126 to move upwards. The movement of the transmission vertical rod 126 causes the petri dish 5 to move upwards. This means that after the cover plate 3 is opened, the petri dish 5 will move a certain distance upwards, making it convenient for staff to pick up. To improve comfort when using the device, the cover plate 3 rotates and moves, causing the connecting rod 122 to move to the bottom. The movement of the connecting rod 122 causes the transmission plate 128 to move to the bottom. The movement of the transmission plate 128 causes the baffle 129 to move to the bottom. The movement of the baffle 129 causes the petri dish 5 to move to the bottom. The movement of the connecting rod 122 causes the transmission rod 123 to move to the bottom. The movement of the transmission rod 123 causes the collar 124 to move to the bottom. After the collar 124 moves, it contacts the air outlet, preventing air from flowing into the air cylinder 121 through the air outlet. This ensures that the device will retract the petri dish 5 when the cover plate 3 is closed after the petri dish is removed, improving the practicality of the device.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
