Description

Technical Field

[0001] This utility model relates to the field of Internet of Things (IoT) terminal technology, and in particular to an IoT data acquisition terminal. Background Technology

[0002] An IoT terminal is a device in the Internet of Things (IoT) that connects the sensor network layer and the transmission network layer, enabling it to collect data and send data to the network layer. It performs multiple functions, including data acquisition, preliminary processing, encryption, and transmission. To provide the best user experience, the terminal should be able to sense changes in the environment and, based on this, optimize its decision-making to select the best service channel for the user.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN216519136U, which discloses an IoT data acquisition terminal. The terminal body includes a U-shaped block fixedly connected to its back. A rotating block is disposed on the inner wall of the U-shaped block, and a connecting block is fixedly connected to the back of the rotating block. A groove is formed on the back of the connecting block. This IoT data acquisition terminal utilizes a rotating shaft to move an internal threaded sleeve, which in turn moves a piston within a square air chamber. Under atmospheric pressure, a suction cup secures the terminal body to a wall. Reversing the rotation of the shaft detaches the suction cup from the wall, making installation and removal of the terminal body more convenient.

[0004] However, the four suction cups in the aforementioned patent have suction channels of unequal length, which leads to uneven distribution of internal air pressure. This unevenness causes differences in the suction force of the suction cups, making the fixation of the terminal body on the wall unstable, thereby affecting the accuracy and stability of data acquisition. In view of this, this application proposes an Internet of Things acquisition terminal based on the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an Internet of Things (IoT) data acquisition terminal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An Internet of Things (IoT) data acquisition terminal includes a terminal body, a support frame fixedly mounted at the bottom of the terminal body, a box fixedly mounted at the bottom of the support frame, a frame fixedly mounted inside the box, and a cavity provided inside the frame. The cavity is cross-shaped and includes four equal-length sub-cavities. The four sub-cavities are symmetrical about the center point of the cavity and extend in mutually orthogonal directions. Four suction cups are provided at the bottom of the box, and the suction cups communicate with the sub-cavities. An air extraction component is connected to the cavity.

[0007] Furthermore, the air extraction assembly includes two support plates fixedly installed on the upper surface of the box body, a winding wheel rotatably installed between the support plates, a handwheel fixedly installed at one end of the winding wheel, an air extraction cylinder fixedly installed at the center of the upper surface of the frame body, the air extraction cylinder communicating with the cavity, one end of the air extraction cylinder penetrating through the box body and having a connecting plate above it, a piston slidably installed inside the air extraction cylinder, a piston rod fixedly installed between the connecting plate and the piston, the piston rod slidably connected to the air extraction cylinder, a fixing hook fixedly installed on the upper surface of the connecting plate, and a pull rope provided between the fixing hook and the winding wheel.

[0008] Furthermore, a first partition plate is fixedly installed at the center point of the cavity, which separates the cavities from each other, and a second partition plate is fixedly installed inside the suction cylinder, which divides the suction cylinder into four channels.

[0009] Furthermore, the bottom of the air extraction cylinder is hollow, and a vent hole is provided at the center of the upper surface of the frame. A sealing block is provided between the first partition plate and the second partition plate.

[0010] Furthermore, the number of pistons is set to four, and the four pistons are respectively arranged in the channel, and the pistons are arc-shaped.

[0011] Furthermore, a guide plate is provided between the air extraction cylinder and the winding wheel, and a guide hole is provided on the guide plate, through which one end of the pull rope passes.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a frame and dividing the cavity, utilizes four equally long cavities formed inside the frame to ensure that the suction path length of each suction cup is the same and the suction force is equal, effectively avoiding the problem of uneven suction caused by inconsistent suction path lengths.

[0013] 2. By setting a first partition plate and a second partition plate, the separation between the first partition plate and the second partition plate allows each chamber to be connected to the suction cylinder separately, and the gas drawn by each piston is also separated from each other, thus avoiding the leakage of a single suction cup from affecting the overall internal air pressure balance.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A box 3 is fixedly installed at the bottom of the support frame 2. A frame 4 is fixedly installed inside the box 3. A cavity 5 is provided inside the frame 4. The cavity 5 is cross-shaped and includes four equal-length sub-cavities 6. By utilizing the four equal-length sub-cavities 6 formed inside the frame 4, the suction path length of each suction cup 7 is the same and the suction force is equal, effectively avoiding the problem of uneven suction caused by inconsistent suction path lengths. The four sub-cavities 6 are symmetrical about the center point of the cavity 5 and extend in mutually orthogonal directions. Four suction cups 7 are provided at the bottom of the box 3. The suction cups 7 are interconnected with the sub-cavities 6. An air extraction component is connected to the cavity 5.

[0018] Reference Figure 1 , Figure 3 , Figure 4Specifically: the air extraction assembly includes two support plates 8 fixedly installed on the upper surface of the box body 3, a winding wheel 9 rotatably installed between the support plates 8, a handwheel 10 fixedly installed at one end of the winding wheel 9, an air extraction cylinder 11 fixedly installed at the center of the upper surface of the frame body 4, the air extraction cylinder 11 communicating with the cavity 5, one end of the air extraction cylinder 11 penetrating through the box body 3 and having a connecting plate 12 above it, a piston 13 slidably installed inside the air extraction cylinder 11, and a connection plate 12 fixedly installed between the connecting plate 12 and the piston 13. A piston rod 14 is slidably connected to an air extraction cylinder 11. A fixing hook 15 is fixedly installed on the upper surface of the connecting plate 12. A pull rope 16 is provided between the fixing hook 15 and the winding wheel 9. When the suction cup 7 is placed on the mounting surface, the handwheel 10 is turned. The handwheel 10 drives the winding wheel 9 to rotate. By pulling the pull rope 16, the connecting plate 12, piston rod 14, and piston 13 move upward, extracting air from the air extraction cylinder 11 and the frame 4. A negative pressure is formed at the suction cup 7, thereby fixing the terminal body 1 to the mounting surface.

[0019] Reference Figure 3 , Figure 6-7 Specifically: a first partition plate 17 is fixedly installed at the center point of the cavity 5, which separates the cavities 6 from each other; a second partition plate 18 is fixedly installed inside the suction cylinder 11, which divides the suction cylinder 11 into four channels 19. Through the separation of the first partition plate 17 and the second partition plate 18, each cavity 6 is connected to the suction cylinder 11 separately, and the gas drawn by each piston 13 is also separated from each other, so as to avoid the leakage of a single suction cup 7 from affecting the overall internal air pressure balance.

[0020] Reference Figure 3 , Figure 6 Specifically: the bottom of the air extraction cylinder 11 is hollow, a vent is provided at the center of the upper surface of the frame 4, and a sealing block 20 is provided between the first partition plate 17 and the second partition plate 18.

[0021] Reference Figure 3 Specifically: the number of pistons 13 is set to four, and the four pistons 13 are respectively arranged in the channel 19. The pistons 13 are arc-shaped.

[0022] Reference Figure 4 Specifically: a guide plate 21 is provided between the air pump 11 and the winding wheel 9, and a guide hole 22 is provided on the guide plate 21, and one end of the pull rope 16 passes through the guide hole 22.

[0023] Working principle: This application utilizes four equally long cavities 6 formed inside the frame 4 to ensure that the suction path length of each suction cup 7 is the same and the suction force is equal, effectively avoiding the problem of uneven suction caused by inconsistent suction path length. Place the suction cup 7 on the mounting surface and crank the handwheel 10. The handwheel 10 drives the winding wheel 9 to rotate. By pulling the rope 16, the connecting plate 12, piston rod 14, and piston 13 move upward, drawing out the air from the air pump 11 and the frame 4. A negative pressure is formed at the suction cup 7, thereby fixing the terminal body 1 on the mounting surface. The separation by the first partition plate 17 and the second partition plate 18 ensures that each chamber 6 is connected to the suction cylinder 11, and the gas drawn by each piston 13 is also separated from each other, thus preventing leakage from a single suction cup 7 from affecting the overall internal air pressure balance.
