[0030] like Figure 1-11 As shown:

[0031] A display device for gastrointestinal examination in gastroenterology includes a display screen 101, a frame 102, a track I 105, a horizontal axis 201, a connecting seat 202, a cleaning frame 204 and a cleaning roller 205. The frame 102 is fixed to the rear end of the display screen 101, the track I 105 passes through the frame 102 horizontally, the horizontal axis 201 slides in the track I 105, the two connecting seats 202 are respectively rotatably connected to the two ends of the horizontal axis 201, the two ends of the cleaning frame 204 are respectively connected to the two connecting seats 202, the cleaning roller 205 is rotatably connected in the cleaning frame 204, the cleaning roller 205 is in contact with the front side of the display screen 101, and the outer surface of the cleaning roller 205 is provided with a soft cloth.

[0032] The display screen 101 is used to display gastrointestinal images. When the display screen 101 is stained or dusty and the gastrointestinal images are being viewed, the horizontal axis 201 is controlled to move up and down within the track I 105, and then the cleaning frame 204 is driven to move up and down through the two connecting seats 202, thereby driving the cleaning roller 205 to move up and down, thereby cleaning the front side of the display screen 101, thereby removing the stains or dust on the display screen 101, and then facilitating viewing of gastrointestinal images.

[0033] At the same time, the cleaning roller 205 is driven by the first motor installed on the cleaning frame 204, so that the cleaning roller 205 is driven in the cleaning frame 204, thereby improving the cleaning effect when the cleaning roller 205 contacts the display screen 101 for cleaning.

[0034] like Figure 1-11 As shown:

[0035] Two vertical plates 107 are fixed to the rear end of the frame 102. Both vertical plates 107 are provided with tracks II. The lifting frame 203 is lifted and slid in the two tracks II. The lifting frame 203 is rotatably connected to the horizontal shaft 201, and the horizontal shaft 201 is meshed and transmission-connected with the two vertical plates 107.

[0036] The second motor installed on the lifting frame 203 drives the horizontal shaft 201 to rotate, and then engages with the two vertical plates 107 to make the horizontal shaft 201 remain horizontal in the track I 105 and move up and down, thereby driving the cleaning roller 205 to clean the display screen 101.

[0037] Further:

[0038] The spring I 206 is arranged between the cleaning frame 204 and the two connecting seats 202 .

[0039] Through the elastic force of spring I 206, the cleaning frame 204 drives the cleaning roller 205 to press against the display screen 101, thereby ensuring the contact between the display screens 101 and the display screens 101, and then ensuring the cleaning effect.

[0040] like Figure 1-11 As shown:

[0041] The frame 102 has inclined surfaces at both ends, and arc grooves 103 are provided on both inclined surfaces.

[0042] Through the setting of the inclined surface, when the horizontal axis 201 drives the cleaning frame 204 to move to the uppermost or lowermost end of the display screen 101 through the two connecting seats 202, as the horizontal axis 201 continues to move, the cleaning roller 205 will move to the inclined surface and be affected by the elastic force of the spring I 206, so that the cleaning frame 204 slides on the two connecting seats 202, and then the cleaning roller 205 continues to move in contact with the inclined surface until the cleaning roller 205 falls into the arc groove 103, thereby completing the retraction of the cleaning roller 205 to avoid the cleaning roller 205 always staying on the display screen 101 and affecting viewing. In addition, through the setting of the arc groove 103, the cleaning roller 205 is retracted, the space occupied by the cleaning roller 205 is reduced, and it is more stable.

[0043] like Figure 1-11 As shown:

[0044] Limiting bars 106 are fixed on both sides of the frame 102 at the rear end of the track I 105.

[0045] After the cleaning roller 205 moves to the inclined surface, affected by the space in the frame 102, the horizontal axis 201 will move to the end of the track I 105 and remain stationary, while the cleaning roller 205 is affected by the elastic force of the inclined surface and the spring I 206, and the cleaning frame 204 will continue to move along the inclined surface until it enters the arc groove 103. At this time, the cleaning roller 205 drives the two connecting seats 202 to rotate relative to the frame 102, so that the cleaning roller 205 and the cleaning frame 204 can be closer to the frame 102, saving space.

[0046] When the horizontal axis 201 is driven to move again, the horizontal axis 201 will drive the two connecting seats 202 to move to overcome the elastic force of the spring I 206, and the cleaning roller 205 is limited by the arc groove 103 and remains stationary until the rear ends of the two connecting seats 202 contact the two limit bars 106. The two connecting seats 202 will be blocked by the two limit bars 106 and rotate, thereby driving the cleaning roller 205 to rotate out of the arc groove 103 through the cleaning frame 204 until the rear ends of the two connecting seats 202 are completely fitted with the two limit bars 106. At this time, the cleaning frame 204 is perpendicular to the display screen 101, so that the cleaning roller 205 and the horizontal axis 201 are at the same horizontal height and rise and fall synchronously with the horizontal axis 201 to complete the cleaning of the display screen 101.

[0047] like Figure 1-11 As shown:

[0048] The water tank 108 is connected to the lower part of the frame 102 . The water tank 108 is connected to the arc-shaped groove 103 at the lower end. Valves are provided between the water tank 108 and the arc-shaped groove 103 . The lower end of the frame 102 is connected to the sewage tank 301 .

[0049] When the soft cloth on the cleaning roller 205 is dirty, the cleaning roller 205 is moved into the arc-shaped groove 103 below, and the valve between the water tank 108 and the arc-shaped groove 103 is opened to allow the clean water in the water tank 108 to flow into the cleaning roller 205 in the arc-shaped groove 103. At the same time, the first motor is started to rotate the cleaning roller 205 in the arc-shaped groove 103. The relative friction between the arc-shaped groove 103 and the cleaning roller 205 rubs the soft cloth on the cleaning roller 205, thereby achieving the purpose of cleaning the soft cloth on the cleaning roller 205.

[0050] At the same time, the sewage is collected by the sewage tank 301 .

[0051] like Figure 1-11 As shown:

[0052] The scraper 302 is arranged at the front end of the sewage tank 301, the spring II 303 is arranged between the sewage tank 301 and the lower end of the frame 102, and a baffle 104 is provided at the rear end of the arc groove 103 at the lower end.

[0053] Due to the elastic force of spring II 303, when the cleaning roller 205 slides into the arc-shaped groove 103 at the lower end, the cleaning roller 205 simultaneously presses the scraper 302 downward. As a result, when the cleaning roller 205 enters the arc-shaped groove 103, the elastic force of spring II 303 will press the scraper 302 against the cleaning roller 205. When the soft cloth is cleaned, the scraper 302 will better scrape the soft cloth, scraping out the dirty water in the soft cloth and flowing it into the dirty water tank 301, thereby preventing a large amount of dirty water from being stored in the soft cloth and affecting the cleaning of the display screen 101 by the cleaning roller 205.

[0054] The baffle 104 is provided to block the rear end of the arc groove 103 , thereby preventing the sewage on the cleaning roller 205 from being thrown away at will when the cleaning roller 205 cleans the cleaning roller 205 .

[0055] like Figure 1-11 As shown:

[0056] The two fixed gears 109 are respectively fixed at the middle of the two vertical plates 107, the bracket 401 is connected between the two fixed gears 109, the arm seat 501 is connected to the rear end of the bracket 401, the arm seat 501 is fixed to the upper end of the lifting rod 506, the support sleeve 507 slides on the outside of the lifting rod 506, the weight seat is fixed at the lower end of the support sleeve 507, the lifting screw 508 rotates at the upper end of the lifting rod 506, and the lifting screw 508 is threadedly connected to the threaded pipe in the support sleeve 507.

[0057] By starting the third motor installed at the upper end of the lifting rod 506, the lifting screw 508 is driven to rotate, and then the threaded tube in the support sleeve 507 is threadedly driven, so that the lifting screw 508 drives the lifting rod 506 to move up and down in the support sleeve 507, thereby driving the entire display screen 101 to move up and down, and then achieving the level of adjusting the horizontal height of the display screen 101;

[0058] The weight seat is placed on the ground to keep the support sleeve 507 perpendicular to the ground.

[0059] like Figure 1-11 As shown:

[0060] A gear shaft 402 and a worm 403 are rotated on the bracket 401 . The worm 403 is meshed and connected to the middle of the gear shaft 402 . The gear shaft 402 is meshed and connected to the two fixed gears 109 .

[0061] The worm 403 is driven by the fourth motor installed on the bracket 401, thereby driving the gear shaft 402, so that the gear shaft 402 rotates and engages with the two fixed gears 109 to rotate, thereby causing the two fixed gears 109 to rotate on the bracket 401, thereby forming an upward and downward orientation adjustment of the display screen 101.

[0062] like Figure 1-11 As shown:

[0063] The screw 505 is rotatably connected to the support arm seat 501, the lifting plate 503 is threadedly connected to the screw 505, the friction block 502 is connected to the lifting plate 503, the friction block 502 penetrates the support arm seat 501 and contacts the bracket 401, and the spring III 504 is arranged between the lifting plate 503 and the friction block 502, so that the friction block 502 presses against the bracket 401.

[0064] When the display screen 101 needs to be adjusted to rotate left or right, the display screen 101 is directly pushed, and the display screen 101 drives the bracket 401 to rotate on the support arm seat 501. The elastic force of the spring III 504 causes the friction block 502 to press against the bracket 401, generating friction, thereby forming a friction limit between the support arm seat 501 and the support arm seat 501, thereby stabilizing the direction of the display screen 101.

[0065] The lifting plate 503 is driven by rotating the screw 505 so that the lifting plate 503 is lifted and lowered on the screw 505 , thereby adjusting the degree of compression of the spring III 504 , thereby adjusting the friction force of the friction block 502 on the bracket 401 .

[0066] The motors in the above embodiments can all be remotely controlled through the module, thereby making it easier for medical staff to clean or adjust the direction of the display screen through the controller remote control device.
