[0057] 101 , the main control box 1 is placed in the correct position, and the main control box 1 is placed in the correct position, so that the main control box 1 can be placed in the correct position.

[0058] It should be noted that the daughter card 100 is installed on the back side of the back plate 2 of the display unit, and the first guide rail bracket 102 is installed on the back side of the back plate 2 of the display unit.

[0059] In this embodiment, the anti-reverse insertion member 101 includes a support portion 1011 and a sliding portion 1012 connected to the support portion 1011. The support portion 1011 is connected to the first guide rail bracket 102, and the sliding portion 1012 is slidably connected to the groove wall of the guide groove 11. The support portion 1011 is connected to the first guide rail bracket 102, so that the sliding portion 1012 can slide and cooperate with the guide groove 11 under the support of the support portion 1011. If the main control box 1 is installed upside down, the sliding portion 1012 will not be able to slide and cooperate with the guide groove 11 due to its height.

[0060] Furthermore, the display terminal structure with separated display and control further includes a first fastener 103, which passes through the support portion 1011 and is connected to the first guide rail bracket 102. Specifically, the first fastener 103 can be a bolt, which passes through the support portion 1011 and is threadedly connected to the first guide rail bracket 102.

[0061] Furthermore, two first guide rail brackets 102 are provided and symmetrically arranged on both sides of the main control box 1, and two anti-reverse insertion members 101 are provided and are arranged one-to-one with the first guide rail brackets 102. By providing two anti-reverse insertion members 101, the main control box 1 can be smoothly plugged into the daughter card 100.

[0062] In one embodiment, if Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, the structure of the display and control separated display terminal includes a display unit and a control unit arranged on the display unit. The control unit includes a cover body 8, a main control box 1, a daughter card 100, a baffle assembly 200, and a display member 300. The daughter card 100 is installed on the back of the display unit and is arranged opposite to the main control box 1. The cover body 8 covers the daughter card 100 and the main control box 1. The baffle assembly 200 is installed on the back of the display unit and is located at the position of the daughter card 100. The display member 300 is installed on the cover body 8 and exposes the cover body 8.

[0063] During the process of the main control box 1 being inserted into the daughter card 100, the main control box 1 abuts against the baffle assembly 200, and the display member 300 displays the first state. Specifically, the daughter card 100 is installed on the back of the backplane 2 of the display unit, and the baffle assembly 200 is installed on the back of the backplane 2 of the display unit.

[0064] It can be understood that the daughter card 100 of the structure of the display and control separated display terminal is installed on the back of the display unit and is arranged opposite to the main control box 1. The cover body 8 covers the daughter card 100 and the main control box 1. The baffle assembly 200 is installed on the back of the display unit and is located at the position of the daughter card 100. The display member 300 is installed on the cover body 8 and exposes the cover body 8. During the process of the main control box 1 being inserted into the daughter card 100, the main control and abuts against the baffle assembly 200, and the display member 300 displays the first state, so that the main control box 1 and the daughter card 100 are inserted in place without confirmation after power-on, which is convenient and fast.

[0065] It should be noted that when the main control box 1 and the daughter card 100 are not inserted in place, the display member 300 displays the second state. The first state can be a green light, and the second state can be a red light. Since the main control box 1 will abut against the baffle assembly 200 during the insertion process, the action signal of the baffle assembly 200 is transmitted to the display member 300, so that the display member 300 can display the first state or the second state. The power supply of the display member 300 can be a button battery.

[0066] In this embodiment, the baffle assembly 200 includes a baffle 201, a connecting member 202, and a positioning pin 203. The baffle 201 is provided with a receiving space 2011 and a first through hole 2012 communicating with the receiving space 2011. The connecting member 202 is installed in the receiving space 2011 and connected to the positioning pin 203. The positioning pin 203 protrudes from the first through hole 2012 to the outside of the baffle 201. During the process of the main control box 1 being inserted into the sub-card 100, the main control box 1 abuts against the positioning pin 203, and the positioning pin 203 drives the connecting member 202 to move in the receiving space 2011. Specifically, as the main control box 1 moves towards the sub-card 100, the main control box 1 abuts against the positioning pin 203 and drives the positioning pin 203 to move along the first through hole 2012. The positioning pin 203 drives the connecting member 202 to move in the receiving space 2011. When the main control box 1 is inserted into the sub-card 100 in place, the positioning pin 203 stops moving. At this time, the display member 300 senses the action signal of the connecting member 202, so that the display member 300 displays the first state.

[0067] Further, the baffle assembly 200 further includes an elastic member 204. The elastic member 204 elastically abuts against the connecting member 202 and the cavity wall of the receiving space 2011. The elastic member 204 can be a spring. By providing the elastic member 204, after the main control box 1 is pulled out of the sub-card 100, the elastic deformation force of the elastic member 204 can drive the connecting member 202 to drive the positioning pin 203 to reset.

[0068] Further, the baffle assembly 200 further includes a connecting column 205. The baffle 201 is further provided with a second through hole 2013 communicating with the receiving space 2011. The connecting column 205 is connected to the connecting member 202 and disposed in the second through hole 2013. The elastic member 204 passes through the connecting column 205. By providing the connecting column 205, after the elastic member 204 undergoes elastic deformation, the connecting column 205 will prevent the elastic member 204 from being distorted to one side, thereby improving the use effect of the elastic member 204.

The first guide rail bracket 102 is installed on the back of the display unit, and the first bearing 301 is rotatably connected to the first guide rail bracket 102.

[0070] During the process of the main control box 1 being inserted into the sub-card 100, the side wall of the main control box 1 is in rolling contact with the first bearing 301.

[0071] It can be understood that the daughter card 100 of the display and control separation display terminal structure is installed on the back of the display unit and is disposed opposite to the main control box 1. The first guide rail bracket 102 is installed on the back of the display unit. The first bearing 301 is rotatably connected to the first guide rail bracket 102. During the process of the main control box 1 being inserted into the daughter card 100, the side wall of the main control box 1 is in rolling contact with the first bearing 301, so that the first bearing 301 and the side wall of the main control box 1 are in a rolling guiding manner, which can effectively reduce the friction force and will not cause scratches and abrasions on the sheet metal surface of the main control box 1, thereby improving the smoothness of the insertion and extraction of the main control box 1.

[0072] It should be noted that the daughter card 100 is installed on the back of the backplane 2 of the display unit, and the first guide rail bracket 102 is installed on the back of the backplane 2 of the display unit.

[0073] In this embodiment, a plurality of first bearings 301 are provided and are arranged at intervals along the extending direction of the first guide rail bracket 102.
