DETAILED DESCRIPTION

[0018] A screen angle adjustment device, such as Figure 1-4 As shown, it includes a support plate 1, an adjustment structure is provided on the support plate 1, and a display screen 2 is provided on the adjustment structure; the adjustment structure includes a rotating column 4 rotatably connected to the support plate 1, the display screen 2 is rotatably connected to the rotating column 4, and a rotating locking component cooperating with the rotating column 4 is provided on the support plate 1; a support frame 5 is fixedly connected to the rotating column 4, a slide cylinder 6 is rotatably connected to the support frame 5, a slide rod 7 is slidably connected to the slide cylinder 6, the slide rod 7 is rotatably connected to the display screen 2, and a fixing component cooperating with the slide rod 7 is provided on the slide cylinder 6.

[0019] When the utility model is in use, the display screen 2 is rotationally adjusted by cooperating with the rotating column 4 and the rotating locking assembly; when the display screen 2 is flipped up and down along the rotating column 4, the display screen 2 drives the slide cylinder 6 to rotate along the support frame 5 through the slide rod 7, and the slide rod 7 slides along the slide cylinder 6, and the slide cylinder 6 and the slide rod 7 are fixed by the fixing assembly, thereby fixing the display screen 2; in summary, the display screen 2 can be horizontally rotated with the rotating column 4, and the display screen 2 can also be flipped up and down along the rotating column 4, so that the display screen 2 corresponds to the patient, thereby improving the adaptability of the display screen 2.

[0020] Furthermore, the rotation locking assembly includes a locking block 3 fixed to the support plate 1, and an outer ratchet 9 is provided on the locking block 3; a synchronization plate 10 is fixed to the rotation column 4, and an outer pawl that cooperates with the outer ratchet 9 is rotatably connected to the synchronization plate 10; an inner ratchet 11 is also provided on the locking block 3, and an inner pawl that cooperates with the inner ratchet 11 is also rotatably connected to the synchronization plate 10, and the inner pawl and the outer pawl are coaxially fixed with a shift rod 8.

[0021] By cooperating between the inner ratchet 11 and the inner pawl, and between the outer ratchet 9 and the outer pawl, the rotating column 4 can be limited in both directions. When the rotating column 4 needs to be rotated, the inner pawl and the outer pawl can be driven to rotate by the lever 8, thereby separating the inner pawl from the inner ratchet 11 and the outer pawl from the outer ratchet 9, so that the rotating column 4 can be rotated.

[0022] Furthermore, the fixing assembly includes ratchets 13 evenly distributed along the axial direction of the slide cylinder 6, and a rotating block 17 is rotatably connected to the slide rod 7; the rotating block 17 is provided with a clamping rod cooperating with the ratchets 13, the slide rod 7 is provided with a guide groove 16 cooperating with the clamping rod, and a shifting block 15 is fixedly connected to the clamping rod.

[0023] The slide bar 7 and the slide cylinder 6 are fixed by the rotating block 17 and the clamping rod thereon cooperating with the ratchet 13. In addition, the clamping rod and the ratchet 13 can be separated by the shifting block 15, thereby improving the convenience of the present application.

[0024] Furthermore, the rotating block 17 is provided with a separation slot 19 and a connection slot, and the slide bar 7 is provided with a spring piece 18 that cooperates with the separation slot 19 and the connection slot; when the rotating block 17 rotates, when the card rod on the rotating block 17 is separated from the ratchet 13, the spring piece 18 cooperates with the separation slot 19, and when the card rod on the rotating block 17 is engaged with the ratchet 13, the spring piece 18 cooperates with the connection slot, such as Figure 4 shown.

[0025] Furthermore, the slide cylinder 6 is provided with a separation slope 14 that cooperates with the clamping rod, and the slide cylinder 6 is also provided with a reset slope 12 that cooperates with the clamping rod; through the setting of the separation slope 14 and the reset slope 12, the clamping rod can automatically engage or disengage with the ratchet 13, thereby improving the convenience of the present application.

[0026] The working process of the utility model is:

[0027] When the utility model is in use, when the display screen 2 needs to be rotated, the inner pawl and the outer pawl are driven to rotate by the lever 8, thereby separating the inner pawl from the inner ratchet 11, and separating the outer pawl from the outer ratchet 9, so that the rotating column 4 can rotate, and the rotating column 4 drives the display screen 2 to rotate; after the rotation of the display screen 2 is completed, the inner pawl and the outer pawl are driven to rotate by the lever 8, so that the inner pawl is engaged with the inner ratchet 11, and the outer pawl is engaged with the outer ratchet 9, so as to limit the rotating column 4.

[0028] When the display screen 2 needs to be adjusted by flipping up and down along the rotating column 4, when flipping down, the display screen 2 drives the slide bar 7 to slide along the slide cylinder 6, and the slide bar 7 slides along the ratchet 13 through the clamping rod. Under the action of the ratchet 13, the clamping rod drives the rotating block 17 to rotate. Under the action of the spring piece 18 and the connecting slot, the rotating block 17 drives the clamping rod to re-clamp between the adjacent ratchet teeth 13, so that the clamping rod and the rotating block 17 cooperate to automatically limit and fix the slide bar 7 and the slide cylinder 6; when the slide bar 7 slides the maximum distance When the lever contacts the separation slope 14, the spring piece 18 is inserted into the separation slot 19 under the action of the separation slope 14, so that the lever is separated from the ratchet 13. At this time, the slide bar 7 can be quickly reset to the shortest sliding distance, so that the lever can drive the rotating block 17 to rotate under the action of the reset slope 12, so that the spring piece 18 is inserted into the connection slot again, and the slide bar 7 can continue to be limited and fixed. In addition, the rotating block 17 can be driven to rotate by the lever 8 to perform arbitrary adjustments, thereby improving the convenience of the present application.
