Thus, features identified with "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 to 6, the embodiment of the present application provides a temperature box with a safety self-locking device, including a box body 1, a box door 2 and a temperature control system, the box door 2 and the box body 1 are rotatably connected, the temperature control system is installed in the box body 1, a pressure transmitter and a pressure pipe are also installed in the box body 1, a pressure switch is provided on the pressure pipe, and a self-locking component 3 is provided on the box door 2, the self-locking component 3 includes a lock body 4, a lock tongue 5, a driving structure and a controller, a circular groove 41 is provided in the lock body 4, one side of the circular groove 41 is connected to a slide groove, the lock tongue 5 is slidably installed in the slide groove, the driving structure is installed in the circular groove 41, the driving structure is used to drive the lock tongue 5 to retract and retract, and the controller is electrically connected to the driving structure; the driving structure includes a rotating shaft 6, a rotating ring 61 is sleeved on the rotating shaft 6, and a disc 62 is fixedly connected to the rotating ring 61, and the disc 62 rotates along the edge of the circular groove 41; a lock hole 11 is provided on the side of the box body 1, the lock hole 11 corresponds to the slide groove, and the lock tongue 5 is engaged with the lock hole 11.

[0032] Working principle and effect:

[0033] The self-locking component 3 is connected to the lock tongue 5 by a driving structure, and the controller is connected to the driving mechanism. The controller drives the extension and contraction of the lock tongue 5 by receiving the user's operation instruction or the switch signal given by the pressure switch. Specifically, the driving motor 65 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the rotating ring 61 and the disc 62 to rotate along the edge of the circular groove 41. Figures 3 and 4 As shown, when a closing signal is received, the driving motor 65 drives the rotating shaft 6 to drive the disc 62 to rotate clockwise toward the lock tongue 5, pushing the lock tongue 5 out of the slide groove, so that the lock tongue 5 slides into the lock hole 11, thereby automatically locking the door 2.

[0034] When the pressure reaches the set value, the pressure switch works and outputs a relay closing signal. The controller extends the lock tongue 5 through the driving structure, and cooperates with the lock hole 11 on the box body 1 to realize automatic locking of the box door 2. At this time, even if a certain force is applied from the outside, the box door 2 cannot be opened. When the box door 2 needs to be opened, the user needs to send an unlocking command to the controller through a preset unlocking method (such as entering a password, fingerprint recognition, etc.). After receiving the command, the controller drives the lock tongue 5 to retract and release the locked state of the box door 2.

[0035] By setting up the self-locking component 3, it is ensured that the door 2 remains closed under certain conditions, effectively preventing the door 2 from opening due to misoperation or negligence, and preventing safety accidents; the user can easily open the door 2 through the preset unlocking method without the need for additional tools or steps, and the operation is simple and quick.

[0036] In one embodiment, Figure 4As shown, a limiting rod 63 is provided in the circular groove 41. The limiting rod 63 is arranged on one side of the rotating shaft 6 and is located near the lock tongue 5. The limiting rod 63 can provide further support for the disc 62 and at the same time, it can play a limiting role. When the connection between the disc 62 and the rotating ring 61 touches the top of the limiting rod 63, the disc 62 completely pushes the lock tongue 5 into the lock hole 11, and the drive motor 65 stops working.

[0037] In one embodiment, Figure 3 or Figure 4 As shown, two top corners at one end of the lock tongue 5 are provided with chamfered corners 51, and the chamfered corners 51 are located at the end close to the disc 62. In order to facilitate the disc 62 to push the lock tongue 5 into the lock hole 11, the two top corners of the lock tongue 5 close to the disc 62 are set as chamfered corners 51, and the disc 62 can smoothly push the lock tongue 5 out, reducing friction resistance and avoiding damage to the disc 62.

[0038] In one embodiment, a bearing for the rotating shaft 6 is provided at the connection between the rotating shaft 6 and the lock body 4. The bearing for the rotating shaft 6 is provided to facilitate the installation of the rotating shaft 6.

[0039] In one embodiment, Figure 5 As shown, a mounting bracket 66 is provided in the mounting shell 64, and the drive motor 65 is fixedly mounted in the mounting shell 64 via the mounting bracket 66. The mounting bracket 66 is provided to facilitate the installation of the drive motor 65.

[0040] In one embodiment, the door 2 is also equipped with an alarm device. To enhance the safety of the incubator, the present invention also includes an alarm device on the door 2. If the door 2 is opened illegally or the temperature inside the incubator becomes abnormal, the alarm device will issue an alarm signal, prompting the user to take prompt action. Furthermore, the incubator can be equipped with surveillance cameras and sensors to monitor the incubator's status and surrounding environment in real time. The use of intelligent devices such as alarms, surveillance cameras, and sensors enables real-time monitoring and intelligent management of the incubator, further enhancing its safety and reliability.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
