[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-5 As shown, a multi-channel data acquisition terminal includes a connection module 1, an adapter module 2, and an acquisition interface module 7. The upper surface of the connection module 1 is provided with a main output terminal 3 and a power terminal 4. The surfaces of the adapter module 2 and the connection module 1 are equipped with a connection component 5. The connection component 5 includes several T-shaped connection slots 51, a T-shaped connection frame 52, an adapter 53, and a conveyor head 54. The connection slots 51 are respectively opened on the side walls of the connection module 1 and several adapter modules 2. The connection frame 52 is fixedly installed on the side wall of the adapter module 2. The connection slots 51 and the connection frame 52 are symmetrically distributed on both sides of the installed adapter module 2. The side wall of the adapter module 2 is provided with a sliding groove 6. The conveyor head 54 is slidably installed inside the sliding groove 6. The adapter 53 is fixedly installed on the side walls of the connection module 1 and the adapter module 2. The adapter 53 in the connection module 1 is electrically connected to the main output terminal 3 for outputting the acquired data.

[0021] Specifically, the main output terminal 3 is used to output the collected data, and the power terminal 4 is used to connect to the power cord to supply power to the terminal. In use, the same number of adapter modules 2 are connected one by one according to the number of data acquisition terminal sensors to be installed, and then the front-end adapter module 2 is connected to the connecting module 1. This allows for modular adjustment of the number of adapter modules 2, which is convenient for users to flexibly adjust according to the number of data acquisition terminal sensors to meet the needs of installing different numbers of data acquisition terminal sensors. When the adapter module 2 is connected to the connecting module 1, the connecting bracket 52 is inserted horizontally into the connecting slot 51, and then the vertical push of the conveyor head 54 slides and engages with the adapter 53. Similarly, when the adapter module 2 is connected to the adapter module 1, the above steps are also used to realize the installation of the adapter module 2. The conveyor head 54 and the adapter 53 can limit the adapter module 2 to prevent the connecting bracket 52 from sliding out of the connecting slot 51, thereby improving the stability of the installation of the adapter module 2 and the connecting module 1.

[0022] An elastic element 55 is fixedly installed between the inner wall of the chute 6 and the side wall of the conveyor head 54. The elastic element can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., with a coil spring being preferred.

[0023] Specifically, the elastic force of the elastic element 55 pushes the conveyor head 54 to press tightly against the adapter 53, thereby improving the stability of the connection between the two.

[0024] The connecting component 5 also includes a limiting post 56, which is fixedly installed at the bottom of the acquisition interface module 7. The upper surface of the adapter module 2 has an opening for the limiting post 56 to pass through, and the limiting post 56 is used to limit the conveyor head 54 by passing through the opening.

[0025] Specifically, after the acquisition interface module 7 is installed, the limiting post 56 passes through the opening to limit the conveyor head 54, thereby preventing the conveyor head 54 from falling off the adapter 53 during use.

[0026] The top of the adapter module 2 is fixedly equipped with an adapter 2 8. The adapter module 2 has a built-in adapter controller. The adapter controller is electrically connected to the adapter 2 8, the conveying head 1 54 and the adapter 1 53 of the adapter module 2. The bottom of the acquisition interface module 7 is fixedly equipped with an output head 2 9 and the top of the acquisition interface module 7 is fixedly equipped with an acquisition head 10.

[0027] Specifically, output head 29 is used to connect to adapter 28 for outputting collected data, and acquisition head 10 is used to connect to the acquisition terminal sensor to transmit collected data.

[0028] Two U-shaped guide plates 11 are fixedly installed on the top of the adapter module 2. The guide plates 11 are used to guide the acquisition interface module 7 so that the output head 2 9 can be accurately connected with the adapter.

[0029] Locking components 12 are mounted on the surfaces of the adapter module 2 and the acquisition interface module 7. The locking components 12 include two slide grooves 121. The upper surface of the slide grooves 121 is formed on the upper surface of the adapter module 2. A slider 122 is slidably connected inside the slide grooves 121. A rotating head 123 is rotatably connected to the surface of the slider 122. A threaded connector 124 is fixedly provided at one end of the rotating head 123. The locking components 12 also include two threaded grooves 125. The threaded grooves 125 are tapped and formed on the lower side wall of the adapter module 2.

[0030] Specifically, when the acquisition interface module 7 is connected to the adapter module 2, the slider 122 is pushed so that the threaded connector 124 abuts against the threaded groove 125. Then, the rotating head 123 is rotated to drive the threaded connector 124 to be threadedly connected to the threaded groove 125 until the rotating head 123 is tightened, thereby fixing the acquisition interface module 7 and preventing the acquisition interface module 7 from falling off.

[0031] The side wall of the slider 122 is fixedly connected to an elastic element 126, and the end of the elastic element 126 away from the slider 122 is fixedly connected to the inner wall of the groove 121.

[0032] Specifically, the elastic force of the elastic element 126 pushes the slider 122 to slide, thereby increasing the distance between the two sliders 122, so that the threaded joint 124 exits the guide plate 11 to avoid obstructing the downward movement of the acquisition interface module 7.

[0033] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0034] It is worth mentioning that the technical features such as the data acquisition terminal sensor involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0035] Working principle: During use, the same number of adapter modules 2 are connected one by one according to the number of data acquisition terminal sensors to be installed, and then the front-end adapter module 2 is connected to the connecting module 1. This allows for modular adjustment of the number of adapter modules 2, which is convenient for users to flexibly adjust according to the number of data acquisition terminal sensors to meet the needs of installing different numbers of data acquisition terminal sensors. When connecting adapter module 2 to connecting module 1, the connecting bracket 52 is inserted horizontally into the interior of the connecting slot 51, and then the vertical push conveyor head 54 slides and engages with the adapter connector 53. Similarly, when connecting adapter module 2 to adapter module 1, the above steps are also used to realize the installation of adapter module 2. The conveyor head 54 and adapter connector 53 can limit the adapter module 2 to prevent the connecting bracket 52 from sliding out of the connecting slot 51, thereby improving the stability of the installation of adapter module 2 and connecting module 1.

[0036] When installing the acquisition interface module 7, connect its bottom output head 9 to the adapter 8. Push the slider 122 to make the threaded connector 124 abut against the threaded groove 125. Then, rotate the rotating head 123 to drive the threaded connector 124 to be threadedly connected to the threaded groove 125 until the rotating head 123 is tightened, thereby fixing the acquisition interface module 7 and preventing it from falling off. The limiting post 56 passes through the opening to limit the conveyor head 54, thereby preventing the conveyor head 54 from falling off the adapter 53 during use.
