Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] As Figures 1 to 5 shown:

[0047] Embodiment 1: The present invention provides an adjustable oral cavity dilator for oral care, including an electric lifting table 1, a positioning mechanism 2 and an oral cavity dilating mechanism 3:

[0048] The positioning mechanism 2 includes a positioning frame assembly 21 fixedly connected to the electric lifting table 1 by bolts. A set of sliding frame assemblies 22 are slidably arranged inside the positioning frame assembly 21, and a positioning assembly 23 is further arranged on the positioning frame assembly 21;

[0049] The oral cavity dilating mechanism 3 includes a limiting sleeve assembly 31 fixedly installed on the sliding frame assembly 22. One end of the limiting sleeve assembly 31 is provided with an adjusting rod assembly 32, and one end of the adjusting rod assembly 32 is rotatably connected to an oral cavity dilating frame assembly 33;

[0050] The positioning assembly 23 positions the sliding frame assembly 22;

[0051] Among them, when in use, the electric lifting table 1 is controlled to work so that the positioning mechanism 2 and the oral cavity opening mechanism 3 reach appropriate heights;

[0052] Rotate the oral cavity opening frame assembly 33 around the adjusting rod assembly 32 so that the oral cavity opening frame assembly 33 is located on the dental chair;

[0053] Control the electric lifting table 1 to move downward so that the oral cavity opening frame assembly 33 is partially stuck in the patient's oral cavity, and pull the limit sleeve assembly 31 so that the adjusting rod assembly 32 drives the oral cavity opening frame assembly 33 to move. The movement of the oral cavity opening frame assembly 33 can open the patient's oral cavity, thus facilitating the staff to perform oral treatment;

[0054] When the limit sleeve assembly 31 moves, the sliding frame assembly 22 will move along the positioning frame assembly 21. At the same time, when the sliding frame assembly 22 moves, the positioning component 23 will position it, thereby restricting the reset of the sliding frame assembly 22.

[0055] Specifically, the limit sleeve assembly 31 includes a limit sleeve body 311. A chute 312 is opened on the outer side of the limit sleeve body 311, and a plurality of card slots 313 are also opened on one side of the limit sleeve body 311 close to the chute 312;

[0056] The adjusting rod assembly 32 includes an adjusting rod body 321. A positioning block 322 is fixedly connected to the outer side of one end of the adjusting rod body 321, and a shaft rod frame 323 is fixedly connected to the other end of the adjusting rod body 321;

[0057] The positioning block 322 is slidably stuck on the chute 312 and can be rotationally stuck in the card slots 313.

[0058] Specifically, a working groove 324 and a storage groove 325 are also opened on the shaft rod frame 323;

[0059] The oral cavity opening frame assembly 33 includes a third connecting rod 331. A shaft hole frame 332 is fixedly connected to one end of the third connecting rod 331, and an oral cavity opening frame member 333 is fixedly connected to the other end of the third connecting rod 331;

[0060] The shaft hole frame 332 is rotationally stuck on the shaft rod frame 323. The third connecting rod 331 can be stuck in the working groove 324, and the third connecting rod 331 can be stuck in the storage groove 325.

[0061] Specifically, the oral cavity opening frame member 333 includes an arc-shaped frame 3331, and an expansion groove 3332 is arranged on one side of the arc-shaped frame 3331.

[0062] As can be seen from the above, the third connecting rod 331 rotates around the shaft rod frame 323 through the shaft hole frame 332. When the third connecting rod 331 is stuck in the storage groove 325, the oral cavity opening frame assembly 33 is in a storage state;

[0063] When the connecting rod three 331 is clamped in the working groove 324, the oral cavity dilator assembly 33 is in a use state;

[0064] In the use state, the arc-shaped frame 3331 can be partially clamped on both sides of the patient's oral cavity, and the expansion groove 3332 can increase the oral operation space for the staff;

[0065] When the positioning block 322 is located in the sliding groove 312, the adjusting rod body 321 can slide along the limiting sleeve body 311. When adjusted to the appropriate height, the rotating shaft rod frame 323 makes the adjusting rod body 321 drive the positioning block 322 to rotate and be clamped on the clamping groove 313, so that the positioning block 322 drives the adjusting rod body 321 to be fixed.

[0066] Such as Figure 7 and Figure 8 shown in:

[0067] Embodiment 2: This embodiment is basically the same as the previous embodiment, the difference is that the positioning frame assembly 21 includes a positioning frame body 211, and one side of the positioning frame body 211 is fixedly connected with a mounting block 212;

[0068] The mounting block 212 is fixedly installed on the electric lifting platform 1 through bolts.

[0069] Specifically, a guide rod 213 is fixedly installed inside the positioning frame body 211;

[0070] The sliding frame assembly 22 includes a sliding frame body 221, and one end of the sliding frame body 221 is fixedly connected with a first spring 222;

[0071] Both the sliding frame body 221 and the first spring 222 are limited and slidably clamped on the guide rod 213, and the first spring 222 drives the sliding frame body 221 to move towards the middle position of the positioning frame body 211;

[0072] The sliding frame body 221 is fixedly connected with the limiting sleeve body 311.

[0073] As can be seen from the above, when it is necessary to open the oral cavity through the oral cavity dilator member 333, moving the limiting sleeve body 311 can make a group of oral cavity dilator members 333 move away from each other, thereby opening the oral cavity;

[0074] When the limiting sleeve body 311 moves, the sliding frame body 221 will move accordingly and compress the first spring 222. At the same time, the sliding frame assembly 22 will be positioned through the positioning assembly 23;

[0075] When the positioning assembly 23 releases the positioning of the sliding frame assembly 22, the first spring 222 will push the sliding frame body 221 to reset, so that the oral cavity dilator assembly 33 no longer opens the patient's oral cavity.

[0076] like Figures 7 to 11 As shown:

[0077] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that a guide block 1 214 and a guide block 215 are fixedly connected to the outer side of the positioning frame body 211;

[0078] The outer side of the sliding frame body 221 is fixedly connected with an outer protruding frame 223, and the outer side of the outer protruding frame 223 is also fixedly connected with a latching tooth 224;

[0079] The positioning assembly 23 includes a connecting bar 231, both ends of the connecting bar 231 are fixedly connected to a connecting rod 1 232, the end of the connecting rod 1 232 is fixedly connected to a trapezoidal block 233, and the outer side of the connecting rod 1 232 is also sleeved with a spring 234;

[0080] The connecting rod 1 232 is limitedly slidably engaged on the guide block 1 214 , and the spring 234 drives the trapezoidal block 233 to be engaged on the locking teeth 224 . When the trapezoidal block 233 is engaged on the locking teeth 224 , the sliding frame body 221 can move in the direction of compressing the spring 1 222 .

[0081] Specifically, a second connecting rod 235 is fixedly connected to the middle of the connecting strip 231, and a pressing block 236 is fixedly connected to the end of the second connecting rod 235;

[0082] The second connecting rod 235 is slidably engaged with the second guide block 215 .

[0083] As can be seen from the above, when the sliding frame body 221 moves, the outer protrusion 223 will also drive the latching tooth 224 to move, and the movement of the latching tooth 224 will cause the trapezoidal latching block 233 to move and compress the second spring 234 on the first guide block 214;

[0084] When the latch teeth 224 stop moving, the second spring 234 is reset to move the trapezoidal block 233 and engage in the grooves between the corresponding latch teeth 224, thereby fixing the sliding frame body 221 and keeping the oral cavity opening frame member 333 in the state of opening the oral cavity;

[0085] When the oral treatment is completed, pushing the pressure block 236 can cause the connecting rod 235 to drive the connecting strip 231 to move. The movement of the connecting strip 231 will cause the trapezoidal block 233 to disengage from the groove between the teeth 224, thereby allowing the sliding frame body 221 to reset under the drive of the spring 1 222. The reset of the sliding frame body 221 will reset the oral opening frame 333 and release the oral opening state.
