Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A dental inspection and expanding device comprises expanding plates 1 which are symmetrically arranged.

[0029] In this embodiment: the existing dental examination and expansion device {publication (announcement) number}: CN210354834U discloses a medical oral dilator. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although the design can avoid entanglement, knotting and slipping, due to the different sizes of the oral cavity of different patients, the existing device is not convenient to adjust, and cannot be adjusted accordingly according to the size of the patient's oral cavity, and cannot meet the needs of different people." In terms of combined use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, an adjustment component 2 and a locking component 3 are added on this basis.

[0030] It should be noted that the mouth expansion plate 1 can be supported by harmless plastic material, and the mouth expansion plate 1 will not damage the oral skin of the patient.

[0031] More specifically:

[0032] like Figures 1 to 4 As shown:

[0033] In combination with the above content: it also includes an adjustment component 2 arranged between the two groups of flaring plates 1; the adjustment component 2 includes an adjustment seat 21 symmetrically fixedly connected to the surface of one group of flaring plates 1 close to the surface of the other group of flaring plates 1, and an adjustment rod 22 symmetrically fixedly connected to the surface of the other group of flaring plates 1 close to the side of the adjustment seat 21, and a rack 24 fixedly connected to the surface of the lower side adjustment rod 22 close to the side of the adjustment seat 21, and an accommodating groove for the sliding of the adjustment rod 22 is provided inside the adjustment seat 21.

[0034] In this embodiment: when it is necessary to adjust the distance between the two groups of expansion plates 1, the rack 24 moves, so that the adjustment rod 22 can be pushed out from the inside of the adjustment seat 21, and the distance between the two groups of expansion plates 1 can be flexibly adjusted according to the size of the patient's mouth, so that it is convenient to use for patients with different oral sizes and for medical staff, thereby expanding the scope of application of the device.

[0035] Going further:

[0036] In an optional embodiment, a gear 26 is provided on one side of the lower adjustment seat 21 near the rack 24, and the gear 26 and the rack 24 are meshingly connected. A drive rod 25 is rotatably connected to one side of the adjustment seat 21 near the gear 26 through a bearing A, and the drive rod 25 and the gear 26 are fixedly connected.

[0037] In this embodiment: when it is necessary to adjust the distance between the two sets of expansion plates 1, the driving rod 25 is rotated, and the rotation of the driving rod 25 can drive the gear 26 to rotate, and then drive the rack 24 to move, so that the adjustment rod 22 can be pushed out from the inside of the adjustment seat 21, and the distance between the two sets of expansion plates 1 can be flexibly adjusted according to the size of the patient's mouth.

[0038] Going further:

[0039] In an optional embodiment, the top end of the driving rod 25 passes through the inner side of the adjusting seat 21 , extends to the outer side of the adjusting seat 21 , and is fixedly connected to a hand wheel 23 disposed above the adjusting seat 21 .

[0040] In this embodiment, the setting of the hand wheel 23 makes it easy for medical staff to rotate the driving rod 25, thereby facilitating the adjustment of the distance between the two groups of flaring plates 1.

[0041] Going further:

[0042] In an optional embodiment, a guide block 27 with a T-shaped structure is fixedly connected to one side of the surface of the rack 24 , and a guide groove 28 for the guide block 27 to slide horizontally is provided inside the adjustment seat 21 .

[0043] In this embodiment, during the movement of the rack 24 , the rack 24 drives the guide block 27 to move in the guide groove 28 provided inside the adjustment seat 21 .

[0044] Going further:

[0045] In an optional embodiment: it also includes a locking assembly 3 arranged between two groups of teeth on the surface of the rack 24; the locking assembly 3 includes a locking rod 31 arranged between the two groups of teeth on the surface, a screw block 32 fixedly connected to the surface of the locking rod 31 on the side away from the rack 24, and a threaded rod 34 threadedly connected to the inside of the screw block 32 on the side away from the locking rod 31.

[0046] In this embodiment: when it is necessary to lock the position of the two groups of expansion plates 1, the threaded rod 34 is screwed. The rotation of the threaded rod 34 can drive the screw block 32 to move inside the limiting groove 33. The movement of the screw block 32 can push the locking rod 31 to move toward the direction close to the rack 24. When the locking rod 31 is inserted between the two groups of teeth on the surface of the rack 24, the rack 24 can be locked at this time, and then the position of the expansion plate 1 can be locked to prevent the patient's mouth from loosening, thereby making it inconvenient for medical staff to examine the patient's oral cavity.

[0047] Going further:

[0048] In an optional embodiment, a limiting groove 33 for the screw block 32 to slide is opened inside the adjustment seat 21, and the threaded rod 34 is rotatably connected to the adjustment seat 21 through the bearing B.

[0049] In this embodiment, during the rotation of the threaded rod 34 , the threaded rod 34 drives the screw block 32 to move in the limiting groove 33 provided inside the adjusting seat 21 .

[0050] Working principle: When the dental staff needs to examine the patient's teeth, the hand wheel 23 is turned at this time. The rotation of the hand wheel 23 can drive the driving rod 25 to rotate, and the rotation of the driving rod 25 can drive the gear 26 to rotate, and then drive the rack 24 to move. The movement of the rack 24 can drive the adjustment rod 22 to move toward the inside of the adjustment seat 21, and then adjust the distance between the two sets of expansion plates 1. When the distance between the two sets of expansion plates 1 is adjusted to be smaller than the patient's oral cavity, the device is placed in the patient's oral cavity, and then the hand wheel 23 is turned in the opposite direction. The reverse rotation of the hand wheel 23 can drive the rod 25 and the gear 26 to rotate in the reverse direction, and then drive the rack 24 to move in the reverse direction, so that the adjustment rod 22 can be pushed out from the inside of the adjustment seat 21. When the distance between the two groups of expanding plates 1 is adjusted to a suitable position, the hand wheel 23 is stopped at this time, and the distance between the two groups of expanding plates 1 can be flexibly adjusted according to the size of the patient's mouth, so that it is convenient for patients with different mouth sizes to use it, and it is convenient for medical staff to use it, which expands the scope of application of the device. Then, the threaded rod 34 is screwed, and the rotation of the threaded rod 34 can drive the screw block 32 to move inside the limiting groove 33. The movement of the screw block 32 can push the locking rod 31 to move in the direction close to the rack 24. When the locking rod 31 is inserted between the two groups of teeth on the surface of the rack 24, the rack 24 can be locked at this time, and then the position of the expanding plate 1 can be locked to prevent the patient's mouth from loosening, thereby making it inconvenient for medical staff to examine the patient's mouth.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
