[0003] Chinese utility model CN221468034U discloses an Internet of Things (IoT) data acquisition terminal. It describes a top cover connection mechanism for the terminal. The mechanism involves rotating limit plates on both sides of the top cover, with a torsion spring on one side of each plate and a locking block at the bottom. The torsion spring's rebound pushes the connecting plate to rotate, causing the locking block at the bottom of the connecting plate to insert into a slot on the outer wall of the data acquisition terminal for a fixed connection, facilitating disassembly.

[0004] However, in existing devices, the connecting plate protrusion lacks a protective structure and is easily damaged by accidental impacts, causing it to rotate and loosen the top plate's fixation. Therefore, a data acquisition terminal less susceptible to such damage was designed to address the aforementioned problem. Utility Model Content

[0033] The Internet of Things (IoT), as the name suggests, is the Internet of Things that connects all things. It is an important component of the new generation of information technology and a crucial stage in the development of the information age. Through intelligent sensing, identification technology, and ubiquitous computing and other communication and sensing technologies, the IoT is widely used in network convergence. Therefore, it is known as the third wave of development in the world's information industry after computers and the Internet. The IoT data acquisition terminal is mainly used in explosion-proof and power-enabled field environments. It is a GPRS terminal device specially designed to meet the requirements of customers and the market. In addition to retaining all the advantages of AX's DATA01, it enables users to keep the device online in real time, making it convenient for users to view data and observe the situation on site.

[0034] In related technologies, limiting plates are rotatably placed on both sides of the top cover, with a torsion spring on one side of the limiting plate and a locking block at the bottom. The torsion spring's rebound pushes the connecting plate to rotate, causing the locking block at the bottom of the connecting plate to insert into a slot on the outer wall of the data acquisition terminal for a fixed connection, facilitating disassembly. However, in existing devices, the protruding connecting plate lacks a protective structure and is easily damaged by accident, causing it to rotate and loosen the top plate's fixation.

[0035] To address some of the problems in the related technologies, this application provides an IoT data acquisition terminal. When the cover plate 12 needs to be installed on the top of the data acquisition terminal body 11, the protrusion 14 at the bottom of the cover plate 12 can be slidably connected to the slide groove 13 to connect the cover plate 12 to the data acquisition terminal body 11. Then, the rotating column 22 is rotated 90 degrees. During the rotation, the pressing block 23 is driven, causing the two ends of the pressing block 23 to separate from the moving plate 24 and align with the inner sidewall of the cover plate 12. During this process, the spring 27 rebounds and pushes the moving plate 24 to move inside the cover plate 12. When the moving plate 24 moves, it pulls the horizontal plate 25 back into the inside of the cover plate 12, and at the same time, the locking block 26 at one end of the horizontal plate 25 is inserted into the slot 21 to fix the cover plate 12.

[0036] This application is described below with reference to the accompanying drawings and specific embodiments:

[0037] This application provides an Internet of Things (IoT) data acquisition terminal, comprising: a data acquisition terminal body 11 with a cover plate 12 on its top; a sliding groove 13 formed on the top of the data acquisition terminal body 11; a protruding strip 14 slidably disposed inside the sliding groove 13 and connected to the cover plate 12; a fixing component 2 disposed inside the cover plate 12, the fixing component 2 comprising: a slot 21 formed on the outer side wall of the data acquisition terminal body 11; a rotating column 22 with its bottom end inserted into the inner cavity of the cover plate 12 and rotatably connected to the cover plate 12; a pressing block 23 penetrated by the rotating column 22 and fixedly connected to the rotating column 22; a moving plate 24 disposed inside the cavity of the cover plate 12; a horizontal plate 25 with one end inserted into the cavity of the cover plate 12 and connected to the moving plate 24; a locking block 26 disposed at one end of the horizontal plate 25 and engaged with the slot 21; and a spring 27 disposed inside the cavity of the cover plate 12 and connected at both ends to the inner side wall of the cover plate 12 and the moving plate 24.

[0038] Specifically, the data acquisition terminal itself is a GPRS type. Its basic principle is to connect to sensing devices through peripheral sensing interfaces, read data from the sensors, process it through a central processing module, and finally send the data to a designated central processing platform via an external communication interface. In essence, an IoT data acquisition terminal typically consists of three parts: a peripheral sensing interface, a central processing module, and an external communication interface.

[0039] Working principle

[0040] Data Acquisition: The IoT data acquisition terminal connects to various sensing devices (such as RFID readers, infrared sensors, environmental sensors, etc.) through peripheral sensing interfaces to read data from these devices.

[0041] Data processing: The collected data is processed through a central processing module, which may include data filtering, cleaning, and transformation to meet specific needs and application scenarios.

[0042] Data transmission: The processed data is sent to the designated central processing platform on the Ethernet via an external communication interface (such as GPRS module, Ethernet interface, WIFI, etc.).

[0043] When it is necessary to install the cover plate 12 onto the top of the data acquisition terminal body 11, the protrusion 14 at the bottom of the cover plate 12 can be slidably connected to the slide groove 13 to connect the cover plate 12 to the data acquisition terminal body 11. Then, rotate the rotating column 22 ninety degrees. During the rotation, it will drive the pressing block 23, so that the two ends of the pressing block 23 are separated from the moving plate 24 and aligned with the inner side wall of the cover plate 12. During this process, the spring 27 rebounds and pushes the moving plate 24 to move inside the cover plate 12. When the moving plate 24 moves, it pulls the horizontal plate 25 back into the inside of the cover plate 12, and at the same time, the locking block 26 at one end of the horizontal plate 25 is inserted into the slot 21 to fix the cover plate 12.

[0044] In some embodiments, the card slots 21, the horizontal plates 25, and the card blocks 26 are arranged symmetrically in four pairs.

[0045] When in use, there are four sets of locking connections that can engage the four parts of the cover plate 12, thereby better fixing the cover plate 12 and improving its firmness.

[0046] In some embodiments, the fixing component 2 further includes a knob 28 disposed on the top of the rotating column 22.

[0047] When in use, the design of the knob 28 makes it easy to grip and control the rotation of the rotating column 22, while the groove on the knob 28 can increase friction when rotating.

[0048] In some embodiments, the fixing component 2 further includes: both ends of the crossbar 29 penetrate the movable plate 24 and are connected to the inner sidewall of the cavity of the cover plate 12.

[0049] The design of the crossbar 29 allows the movable plate 24 to move stably inside the cover plate 12 during use.

[0050] In some embodiments, both ends of the extrusion block 23 are flat.

[0051] When in use, the two ends of the pressing block 23 are designed to be flat, which makes the flat surface fit more stably when in contact with the moving plate 24, and prevents the rotating column 22 from rotating.

[0052] In some embodiments, a stabilizing component 3 is provided inside the rotating column 22. The stabilizing component 3 includes: a positioning hole 31 opened at the top of the cover plate 12; a rectangular rod 32 disposed at the bottom of the rotating knob 28 and inserted into the interior of the rotating column 22 at its bottom end; a base plate 33 disposed at the bottom of the rectangular rod 32; a spring 34 sleeved on the outer side wall of the rectangular rod 32; and an insert rod 35 disposed at the bottom of the rotating knob 28.

[0053] When the rotating column 22 needs to be rotated, the knob 28 can be pulled upwards to pull the rectangular rod 32 out of the rotating column 22, simultaneously disengaging the insertion rod 35 from the positioning hole 31 and releasing its fixation. This allows the rotating column 22 to rotate. When rotation is not needed, the spring 24 rebounds, pushing the base plate 33 downwards and causing the rectangular rod 32 to retract into the rotating column 22, lowering the height of the knob 28 and pushing the insertion rod 35 into the positioning hole 31 for fixation. This further stabilizes the knob 28, preventing it from rotating when not in use.

[0054] In some embodiments, four positioning holes 31 and four insertion rods 35 are provided, and they are arranged in a cross shape in pairs.

[0055] The four-group design allows for a guaranteed 90-degree rotation during use, making it convenient to operate.

[0056] In some embodiments, the stabilizing component 3 further includes a cone 36 disposed at the bottom of the insert 35.

[0057] When in use, the pointed end of the cone 36 can be inserted into the positioning hole 31 more easily.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
