DETAILED DESCRIPTION

[0048] A preferred embodiment of the present application will be described in detail below with reference to the drawings.

[0049] Referring to Figures 1 to 4 The first embodiment of the present application discloses a jaw frame, which comprises a dental model 20 and a jaw frame model 30 for installing the dental model 20, wherein the dental model 20 comprises a model upper jaw 201, a model lower jaw 202, and an articulator assembly 203 for connecting the model upper jaw 201 and the model lower jaw 202. It is explained that the articulator comprises an upper jaw articulator and a lower jaw articulator, and the upper jaw articulator can be installed on the lower jaw articulator in a rotatable and angle-setting manner, the model upper jaw 201 is fixedly installed on the upper jaw articulator, and the model lower jaw 202 is fixedly installed on the lower jaw articulator. This technology is the prior art, and will not be described here.

[0050] The difference from the prior art is that the jaw frame provided by the embodiment further comprises a first locking mechanism 40 arranged between the model upper jaw 201 and the upper jaw frame 301, and used to realize detachable connection of the model upper jaw 201 and the upper jaw frame 301. The first locking mechanism 40 comprises a connecting seat 401 embedded in the bottom of the upper jaw frame 301, and a locking block 402 slidingly arranged on the connecting seat 401. The locking block 402 is provided with a buckling portion 4021, and the buckling portion 4021 is buckled and connected with the clamping portion 2011. Referring to Figure 4 The bottom periphery of the upper jaw frame 301 is formed with a stop ring 3011, and the connecting seat 401 is fixedly installed in the space formed by the stop ring in the bottom of the upper jaw frame 301 by means of a screw, so that the first locking mechanism 40 and the upper jaw frame 301 form an integrated structure.

[0051] The locking block 402 has a locking movement state that is driven by an external force to move the buckling portion 4021 to a set unlocking movement state, and a locking movement state that is driven by the external force to elastically move the buckling portion 4021 to reset after the external force is removed. When the locking block 402 is in the unlocking movement state, the clamping portion 2011 is separated from the buckling portion 4021. When the locking block 402 is in the locking position, the clamping portion 2011 is tightly buckled with the buckling portion 4021. That is, when the locking block 402 is in the unlocking movement state, the model upper jaw 201 can be separated from the upper jaw frame 301 to realize quick disassembly of the model upper jaw 201. When the locking block 402 is in the locking position, the model upper jaw 201 can be locked to the upper jaw frame 301 to realize quick assembly and fixation of the model upper jaw 201.

[0052] For the convenience of description, the state of Figure 2 and Figure 4 is taken as a reference, the opening side of the dental jaw model 20 is defined as an outer side, the side opposite to the outer side is defined as an inner side, and the two sides of the width direction of the track 4011 are respectively defined as a left side and a right side.

[0053] Specifically, the side of the connecting seat 401 facing the upper jaw frame 301 is provided with a track 4011; the locking block 402 is slidingly connected with the track 4011, the side of the track 4011 facing the locking block 402 extends to the outer side of the connecting seat 401 to form a first notch 4012 matched with the locking block 402 on the connecting seat 401; and the end of the track 4011 close to the inner side is provided with a penetrating opening 4013 vertically penetrating the clamping portion 2011.

[0054] Referring to Figure 4 , the track 4011 is a rectangular groove structure opened in the top of the connecting seat 401. When the connecting seat 401 is fixedly installed in the bottom of the upper jaw frame 301, the top slot of the rectangular groove is closed by the upper jaw frame 301, so that the locking block 402 is limited in the track, the sliding of the locking block is ensured to be straight, the sliding jamming of the locking block is avoided, and the smoothness of the movement of the locking block is ensured.

[0055] Further, the locking block 402 further comprises a sliding part 4022 movably arranged in the track 4011; the inner end of the sliding part 4022 is connected with a clamping part 4021 which is slidably arranged in the through hole 4013, and the side end face of the clamping part 4021 towards the sliding part 4022 is an inclined abutting face 40211 arranged from top to bottom and outwardly; the clamping part 2011 is fixedly arranged on the upper jaw 201 of the model by a fixing screw, and the inner end of the clamping part 2011 is a clamping face 20111 arranged in the same direction as the abutting face 40211; when the locking block 402 is in the locked position, the abutting face 40211 and the clamping face 20111 are closely combined and arranged in the through hole 4013. That is, when the dental jaw model 20 is arranged on the jaw frame model 30, the clamping part 2011 on the top of the upper jaw 201 of the model vertically passes through the through hole 4013 and is arranged outside the clamping part 4021, so that when the locking block 402 is driven to move inwardly, the unlocking movement state can be realized, and vice versa, the locking movement state is realized.

[0056] Further, the outer end of the sliding part 4022 extends to the outside of the first gap 4012 and is connected with a driving part 4023, the driving part 4023 is longitudinally arranged near the lower end of the first gap 4012 to form a stop face 40231, when the locking block 402 is in the unlocking state, the stop face 40231 abuts against the connecting seat 401.

[0057] The connecting seat 401 is further provided with two arrangement grooves 4014 arranged on the left and right sides of the track 4011 and communicating with the track 4011, that is, the arrangement grooves 4014 and the track 4011 form a "cross" channel, the vertical section is a track, and the horizontal section is provided with a first tension spring 404 on the vertical section as the axis of symmetry, and the two first tension springs 404 bias the locking block 402 to be in the locked state. Specifically, the connecting rods 403 are symmetrically arranged on the left and right sides of the locking block 402, and the two connecting rods 403 are coaxially arranged and movably arranged in the corresponding arrangement grooves 4014.

That is, the connecting rod 403 is located inside the fixed rod 4015 and can move relative to the fixed rod 4015. That is, the elastic force of the two first tension springs 404 acts on the locking block 402, so that the abutting face 40211 of the clamping part 4021 closely abuts on the clamping face 20111 of the clamping part 2011, and since the abutting face 40211 and the clamping face 20111 are arranged in an inclined manner, the clamping part is fixed.
