[0027] Combined with Figures 1 to 9 as shown:

[0028] The maxillary fixing bracket 100 and the mandibular fixing bracket 200 jointly form a human oral articulator. In order to achieve ergonomics, it is necessary to enable the mandibular fixing bracket to rotate a certain angle and move up and down a certain space relative to the maxillary fixing bracket. Therefore, a tooth socket assembly 300 is provided, and the connection structure can achieve angular rotation and vertical movement.

[0029] The maxillary fixing bracket 100 is provided with a dental socket fixing plate 101 for sliding connection with a connecting structure. Among them, the dental socket fixing plate 101 is vertically formed upward at the inner end of the maxillary fixing bracket 100 and is provided with dental socket fixing holes 102 for locking and assembling with the dental socket assembly 300 and the fixed mandibular component 201.

[0030] A fixed mandibular component 201 can be inserted into the mandibular fixing bracket 200. Specifically, the fixed mandibular component 201 realizes the insertion and loosening of the mandibular fixing bracket 200 and the fixed mandibular component 201 through the assembly of a pin 207 and a pin hole 103.

[0031] Dental socket ball pins 203 are threadedly connected to both side ends of the mandibular fixing bracket 200, and the dental socket ball pins 203 are assembled and connected with the connecting structure.

[0032] Specifically, the dental socket ball pin 203 is connected to a dental socket groove member 303 on the connecting structure.

[0033] Specifically, the dental socket ball pin 203 is provided with a spherical body 208. The spherical body 208 extends into the dental socket groove member 303, and the dental socket ball pin 203 rotates or moves to a certain extent with the spherical body 208 as the base point, driving the mandibular fixing bracket 200 to rotate by a certain angle.

[0034] Specifically, when the mandibular fixing bracket 200 is driven to rotate, the pin 207 and the pin hole 103 are in a loose and non-inserted state at this time.

[0035] Such as Figure 9 As shown, the dental socket groove member 303 is provided with a special-shaped groove 306. The special-shaped groove 306 has a slot hole that is narrow at the front end and wide at the rear end, and the rear end is in interference fit with the spherical body 208. Therefore, the spherical body 208 can rotate or move in the special-shaped groove.

[0036] Specifically, when the angle of the mandibular fixing bracket 200 is adjusted to the required angle, the pin 207 is inserted into the ultra-small hole 103 to fix the mandibular fixing bracket 200, so that the mandibular fixing bracket 200 can be ensured not to loosen at this angle.

[0037] Specifically, one end of the fixed mandibular component 201 is screwed and locked with the dental socket assembly 300 and the dental socket fixing plate 101.

[0038] Among them, the dental socket assembly 300 includes a connecting member 301. Dental socket groove members 303 and mandibular limiting eccentric sleeves 304 are provided at both left and right ends of the connecting member 301. A connecting member groove 302 is provided on the connecting member 301, and a mandibular fixing bracket groove 202 is provided on the fixed mandibular component 201. By inserting a screw through the dental socket fixing hole 102, the connecting member groove 302 and the mandibular fixing bracket groove 202 together, the maxillary fixing bracket 100, the dental socket assembly 300 and the mandibular fixing bracket 200 can be locked.

[0039] Specifically, the groove diameters and areas of the connecting member groove 302 and the lower jaw fixing frame groove 202 are larger than the dental socket fixing hole 102. Therefore, by moving the connecting structure up and down, the fixed lower jaw assembly 201 is driven to move up and down, and the lower jaw fixing frame is driven to move up and down, so that the distance between the upper and lower jaw fixing frames can be adjusted. Among them, it is only necessary to ensure that the dental socket fixing hole 102 always falls within the groove coverage range of the connecting member groove 302 and the lower jaw fixing frame groove 202, and then it can be locked with screws.

[0040] Specifically, there is also a fine-tuning structure 800 on the fixed lower jaw assembly 201. The fine-tuning structure 800 is assembled with the connecting structure by screws. Among them, both the fixed lower jaw assembly 201 and the connecting member 301 are provided with fine-tuning grooves.

[0041] As Figure 3 shown: A pressing plate 205 is provided on the fixed lower jaw assembly 201. A torsion spring and a torsion spring shaft 206 are provided on the pressing plate 205. The torsion spring shaft 206 passes through the torsion spring, so that the pressing plate 205 has a pressing force in one direction.

[0042] Specifically, the pressing plate 205 is bent at a certain angle to conform to the structure of the human oral cavity and has the function of supporting the lower jaw fixing frame 200.

[0043] Specifically, a plug pin 207 is provided on the pressing plate 205. Among them, the plug pin 207 can be fixed to the pressing plate fixing member 201 by welding or by a threaded connection method.

[0044] Specifically, in the state where the pressing plate 205 is not stressed, the plug pin end of the pressing plate 205 always abuts against the outer end of the lower jaw fixing frame 200, so that the lower jaw fixing frame 200 always maintains a certain opening and closing angle. At this time, the plug pin 207 is always inserted into the plug pin hole 100.

[0045] Specifically, when the pressing plate 205 is pressed, under the action of torsion, the plug pin 207 disengages from the plug pin hole 103. At this time, the lower jaw fixing frame 200 is loosened, and the angle of the lower jaw fixing frame can be adjusted.

[0046] Specifically, the upper jaw fixing frame 100 and the lower jaw fixing frame 200 are connected by a tension spring 305, so that the articulator can always maintain a certain tension force, which conforms to ergonomics.

[0047] Specifically, the magnetic dental mold fixing plate 400 adopts a screw locking structure and is provided on both the upper jaw fixing frame 100 and the lower jaw fixing frame 200. Among them, a magnet is provided on the magnetic dental mold fixing plate 400 for magnetically attracting the dental mold, replacing the cumbersome installation of traditional screws. The disassembly and installation are convenient, improving the efficiency of replacing the dental mold, and it can adapt to various models of dental molds.

[0048] Specifically, the magnetic dental mold fixing plate 400 can be adjusted in the front-back orientation by screws to adapt to a more realistic oral environment.

[0049] Specifically, the dental mold is installed with components made of iron materials and used in cooperation with the magnets of this patent.

[0050] Specifically, the dental mold ejection assembly 600 is used to eject the dental mold. Among them, the upper jaw fixing frame 100 and the lower jaw fixing frame 200 are both provided with through holes for the ejection screw 603 to penetrate, and the through holes penetrate through the magnetic dental mold fixing plate 400 until they abut against the dental mold.

[0051] Specifically, when the spring 602 is not stressed, the spring 602 always pushes up the ejection screw 603. The left end of the elastic piece is fixed on the stud 601, and the right end is pushed up by the spring 602. When it is necessary to eject the dental mold, only need to press the pressing part 605 of the elastic pressing piece, so that the spring 602 is stressed and pressed down. At the same time, the ejection screw 603 is pressed down and abuts against the dental mold through the through hole, and at the same time the dental mold is pushed up. When the hand is released, it resets.

[0052] Through the assembly design of the tooth socket groove part 3 and the tooth socket ball pin 203 of the present utility model, the tooth socket ball pin 203 can rotate, slide and be limited and locked in the tooth socket groove part 3. Therefore, the adjustment of the tooth socket ball pin 203 can drive the angle adjustment of the lower jaw fixing frame 200, so that the opening and closing angle of the overall articulator is adjustable, making the articulator more ergonomic and improving the teaching effect.

[0053] Through the tooth socket assembly 300 of the present utility model, it can slide relatively on the upper jaw fixing frame 100, driving the lower jaw fixing frame 200 to slide up and down relative to the upper jaw fixing frame 100, so that the upper space between the upper jaw fixing frame 100 and the lower jaw fixing frame 200 of the articulator is adjustable, making the articulator more ergonomic and improving the teaching effect.

[0054] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
