[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0018] See also Figure 1-4 , a serial port transfer terminal for the Internet of Things, comprising a terminal body 1 with an interface 8 opened at one end face, a terminal inserted into the interface 8 and connected to the interface 8, and a fixing mechanism arranged on the end face of the interface 8 of the terminal body 1 for fixing the position of the terminal, the fixing mechanism comprising a positioning block 2 detachably mounted on the end face of one end of the interface 8 opening, two positioning strips 10 arranged in the positioning groove 9 and symmetrical about the opening position of the limiting hole 6, a rubber strip 11 arranged on the side faces of the adjacent sides of the two positioning strips 10, and a control component arranged on the positioning block 2 and controlling the two positioning strips 10 to approach each other; the two positioning strips 10 are arranged horizontally; a limiting hole 6 opposite to the opening position of the interface 8 is opened on the end face of the positioning block 2, and a positioning groove 9 passing through the limiting hole 6 is opened in the positioning block 2.

[0019] like Figure 1-4As shown, in the prior art, the terminal on the wire is directly passed through the interface 8 of the terminal body 1. During long-term use and plugging and unplugging, the terminal passing through the interface 8 may become loose or even fall off. In this application, a positioning block 2 is installed on one end of the interface 8 provided on the terminal body 1. When installing the terminal, the terminal is first controlled to pass through the limiting hole 6 and pass through the interface 8. After the terminal is connected to the interface 8, the two parallel positioning bars 10 passing through the positioning block 2 are controlled to approach each other to clamp and fix the terminal. Rubber strips 11 are provided on the adjacent side surfaces of the two positioning strips 10. When the terminal is clamped and fixed by the two positioning strips 10, the rubber strips 11 clamp and fix the terminal. On the one hand, it avoids the situation where the positioning strips 10 directly clamp and fix the terminal, causing damage to the surface of the terminal. On the other hand, the rubber strips 11 facilitate increasing the friction between the rubber strips 11 and the terminal, ensuring the stability of the clamping and fixing of the terminal, and the terminal can be easily and stably installed on the terminal body 1, avoiding loosening of the terminal.

[0020] The control component includes two linkage blocks 14 arranged at one end of the two positioning bars 10 and arranged up and down, two connecting rods 15 parallel to each other and arranged in the vertical direction, and a control member arranged on the positioning block 2 and controlling the two linkage blocks 14 to move away from each other. The side of the lower linkage block 14 is connected to one end of the upper positioning bar 10 through one of the connecting rods 15; the side of the upper linkage block 14 is connected to one end of the lower positioning bar 10 through another connecting rod 15.

[0021] like Figure 1-4 As shown, when the two linkage blocks 14 are driven away from each other by the control member, the two positioning bars 10 are driven closer to each other, so that they can pass through the limiting hole 6 and be inserted into the interface 8. At this time, the two positioning bars 10 clamp and fix the wiring terminal, ensuring the fixing stability of the wiring terminal and avoiding the wiring terminal from being plugged in and out of the interface 8 for a long time, which may cause the wiring terminal to become loose or even fall off when inserted into the interface 8.

[0022] The two linkage blocks 14 arranged at the upper and lower parts have end surfaces away from the terminal body 1 and are inclined, and the distance between the adjacent inclined surfaces of the two linkage blocks 14 gradually increases from the terminal body 1 to the end away from the terminal body 1; the control part includes a control block 16 arranged at the opening position formed by the inclined surfaces of the two linkage blocks 14, and a control structure arranged on the positioning block 2 and controlling the movement of the control block 16 toward the terminal body 1, and the end surface of the control block 16 adjacent to one end of the two linkage blocks 14 is an inclined surface that matches the inclined surface of the linkage block 14.

[0023] The control structure includes a positioning screw 12 that is vertically penetrated on the end face of the positioning block 2 away from the terminal body 1, a threaded block 13 that is sleeved on the rod of the positioning screw 12 through a threaded connection, and a control disk 5 that is rotatably set on the end face of the positioning block 2 away from the terminal body 1 and the end face is fixedly connected to the end of the positioning screw 12, and the side of the threaded block 13 is fixedly connected to the side of the control block 16.

[0024] like Figure 2-4 As shown, when the terminal is passed through the limiting hole 6 and connected to the interface 8, the positioning screw 12 is driven to rotate by rotating the control disk 5, and the threaded block 13 which is threadedly connected to the rod of the positioning screw 12 drives the control block 16 to move toward the two linkage blocks 14, and the action between the inclined surfaces pushes the two linkage blocks 14 away from each other, which can drive the two positioning bars 10 to approach each other, and the terminal can be stably fixed in the position in the limiting hole 6 by the two positioning bars 10, and the terminal can be stably installed on the terminal body 1 conveniently and stably, avoiding loosening of the terminal.

[0025] A first mounting hole 3 is provided on the end face of the positioning block 2, and a second mounting hole 7 matching the first mounting hole 3 is provided on the end face of the terminal body 1 where the interface 8 is provided; a mounting bolt 4 which can be connected to the inner thread of the second mounting hole 7 is passed through the first mounting hole 3.

[0026] First, control the positioning block 2 to fit the end face of the terminal body 1, and pass the mounting bolt 4 through the first mounting hole 3 and through the second mounting hole 7 through a threaded connection, so that the position of the positioning block 2 on the terminal body 1 can be fixed, avoiding the modification of the structure of the terminal body 1 and improving the installation efficiency of the positioning block 2.
