[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments.

[0029] See also Figure 1-Figure 6 As shown, the utility model is a corneal topograph with a coverable detection port, comprising a base 1, a connecting seat 2 is arranged on the top of the base 1, and the outer surfaces of the connecting seat 2 are respectively fixedly connected to detection heads 3, and the outer surfaces of the detection heads 3 are rotatably connected to the sealing covers 4, a limiting component 5 is arranged between the sealing covers 4 and the detection heads 3, and an anti-mistaken touch component 6 is arranged on the top of the limiting component 5, and the limiting component 5 is used to fix the sealing covers 4.

[0030] Push the anti-accidental-touch component 6 to rotate so that the anti-accidental-touch component 6 releases the fixation of the limit component 5. At this time, push the limit component 5 to separate it to release the limit fixation of the cover 4. Then, the cover 4 can be rotated to move it away from the front of the detection head 3, and the base 1 and the connecting seat 2 are moved and the position of the detection head 3 is changed so that the detection head 3 can be aligned with the eyes of the person being tested. After use, the cover 4 can be rotated back. During the rotation, the limit component 5 automatically resets and connects and fixes the cover 4 and the detection head 3 to avoid unnecessary rotation of the cover 4. After the anti-accidental-touch component 6 is reset, the limit component 5 can be locked to avoid the cover 4 from opening due to accidental touching of the limit component 5.

[0031] The utility model connects the limit assembly 5 and the anti-accidental touch assembly 6, pushes the anti-accidental touch assembly 6 to rotate upward to release the fixation of the limit assembly 5, and the limit assembly 5 can be separated at this time. After the limit assembly 5 is separated, the limit fixation between the cover 4 and the detection head 3 is released, and the cover 4 is moved away from the front of the detection head 3. When not in use, the cover 4 can be screwed back to the front of the detection head 3 for fixation. The disassembly is relatively convenient, and the cover 4 is not separated from the detection head 3, which can avoid the cover 4 from being lost.

[0032] In one embodiment, for the above-mentioned limiting assembly 5, the limiting assembly 5 includes a first fixing seat 501 and a second fixing seat 506, the first fixing seat 501 is fixedly connected to the outer surface of the detection head 3, the first fixing seat 501 is internally slidably connected with a push rod 502, the outer surface of the push rod 502 is fixedly connected with a ring 503, the outer surface of the ring 503 is fixedly connected with a first spring 504, the first spring 504 is fixedly connected to the inside of the first fixing seat 501, a slot 505 is opened inside the first fixing seat 501, the second fixing seat 506 is fixedly connected to the outer surface of the cover 4, the second fixing seat 506 is internally fixedly connected with a second spring 507, the end of the second spring 507 is fixedly connected with an insertion rod 508, and the insertion rod 508 is inserted into the inside of the slot 505

[0033] The push rod 502 is pushed to drive the ring 503 to move, and the ring 503 compresses the first spring 504. At the same time, the push rod 502 pushes the insertion rod 508 to move, so that the insertion rod 508 compresses the second spring 507. At the same time, the insertion rod 508 retracts into the second fixed seat 506 and separates from the slot 505. At this time, the cover 4 can drive the second fixed seat 506 to rotate, so that the cover 4 is moved away from the front of the detection head 3. After use, the cover 4 is rotated back, and the second spring 507 pushes the insertion rod 508 to reset, so that the insertion rod 508 is plugged into the slot 505 to complete the fixation.

[0034] In one embodiment, for the above-mentioned anti-accidental touch component 6, the anti-accidental touch component 6 includes a round rod 601, a square groove 602 is opened on the outer surface of the first fixed seat 501, the round rod 601 is fixedly connected to the inside of the square groove 602, a rotating rod 603 is opened on the outer surface of the round rod 601, and a card slot 604 is opened on the outer surface of the push rod 502, and the rotating rod 603 is located inside the card slot 604.

[0035] The rotating rod 603 is pushed to rotate through the round rod 601, so that the rotating rod 603 is separated from the slot 604 on the push rod 502, and the limit fixation of the push rod 502 can be released. At this time, the push rod 502 can be pushed to move. When the rotating rod 603 is located in the slot 604 on the push rod 502, the movement of the push rod 502 will be blocked by the rotating rod 603, thereby playing a role in preventing accidental touch, avoiding unnecessary movement of the push rod 502 and causing the cover 4 to open.

[0036] In one embodiment, for the above-mentioned detection head 3, the outer surface of the detection head 3 is fixedly connected to a first ear plate 7, the interior of the first ear plate 7 is rotatably connected to a pin 8, the first ear plate 7 is rotatably connected to a second ear plate 9 through the pin 8, and the second ear plate 9 is fixedly connected to the cover 4.

[0037] The cover 4 drives the second ear plate 9 to rotate via the pin 8, and the pin 8 serves to connect the second ear plate 9 and the first ear plate 7, thereby preventing the cover 4 from being lost due to the separation of the detection head 3.

[0038] In one embodiment, for the above-mentioned connection base 2, a dustproof component 10 is provided on the outer surface of the connection base 2, and a collection box 11 is slidably connected to the outer surface of the connection base 2.

[0040] Pull the limit block 1003 to move upward along the slide groove 1002 to separate the limit block 1003 from the dustproof net 1001, release the limit fixation of the dustproof net 1001, and then rotate the dustproof net 1001 to the top of the collection box 11. At this time, clean the dust on the dustproof net 1001, and the dust will fall directly into the collection box 11. The equipment in the connecting seat 2 can also dissipate heat through the dustproof net 1001.

[0041] In one embodiment, for the above-mentioned connection base 2 , a display screen 12 is fixedly connected to the outer surface of the connection base 2 .

[0042] The display screen 12 is electrically connected to the detection head 3 , and the detection result of the detection head 3 is fed back to the display screen 12 . This is a prior art and will not be described in detail here.

[0043] Through the above technical scheme, 1. through the connection between the limit component 5 and the anti-accidental touch component 6, the anti-accidental touch component 6 is pushed to rotate upward to release the fixation of the limit component 5. At this time, the limit component 5 can be separated. When the limit component 5 is separated, the limit fixation between the cover 4 and the detection head 3 is released. At this time, the cover 4 is moved away from the front of the detection head 3. When not in use, the cover 4 can be rotated back to the front of the detection head 3 for fixation. The disassembly is relatively convenient, and the cover 4 is not separated from the detection head 3, which can avoid the loss of the cover 4. 2. Through the connection between the push rod 502 and the rotating rod 603, the rotating rod 603 is pushed to rotate, so that the rotating rod 603 is separated from the card slot 604 on the push rod 502, and the limit fixation of the push rod 502 is released. Then the push rod 502 is pushed to slide in the first fixed seat 501, and the push rod 502 pushes the insertion rod 508 to retract it into the second fixed seat 506. At this time, the first fixed seat 501 is separated from the second fixed seat 506, and the cover 4 can drive the second fixed seat 506 to rotate around the pin 8. The cover 4 is rotated so that it is moved away from the front of the detection head 3. The cover 4 is screwed back after use. During the rotation, the insertion rod 508 and the second spring 507 are squeezed by the first fixing seat 501 until the insertion rod 508 is aligned with the slot 505. The second spring 507 pushes the insertion rod 508 to return to the inside of the slot 505, so that the cover 4 is fixed on the detection head 3. The assembly and disassembly is relatively convenient, and the cover 4 is never separated from the detection head 3, which can avoid the cover 4 from being lost.
