The jaw frame main body is provided with a tooth mounting groove at a position corresponding to a dental arch. The central position of the outer surface of the jaw frame is integrally provided with an assembly boss, and the central position of the assembly boss is in a screw hole form and used for further mounting the whole device on a jaw frame unfolding support or a human body shaping model.
The inner surface of the jaw frame main body is laid with a muscle layer, and the muscle layer can be laid on the inner surface of the jaw frame main body in a secondary injection molding mode.
The outside of jaw frame main part corresponds human dental arch position, is equipped with the locating rack mounting groove, install the bolt locating rack in the locating rack mounting groove.
The bolt positioning frame is a semi-annular plate body which is similar to a human dental arch, bolt mounting holes are arranged on the bolt positioning frame in an array mode, and the bolt mounting holes are arranged corresponding to the number and the positions of human teeth.
The teeth are separately arranged teeth, and the bottom surfaces of the teeth are in a screw hole form. That is to say, when the assembly, the tooth inserts and sets up in the tooth mounting groove in the jaw frame main part, and the bolt locating rack is arranged in the locating rack mounting groove, and the screw on the bolt locating rack and the screw one-to-one of every tooth bottom use the bolt to penetrate the bolt mounting hole to screw up in the tooth bottom, play the effect spacing alone to every tooth.
Furthermore, the inner surface of the bolt positioning frame, namely the joint surface with the jaw frame main body, is provided with an assembling protrusion, an assembling groove is arranged in the positioning frame mounting groove, and the assembling groove is arranged corresponding to the assembling protrusion, so that the bolt positioning frame can be further positioned conveniently for assembling.
Further, the surface of bolt locating rack, be equipped with the protruding one side that corresponds of assembly promptly and be equipped with the magnetite, the magnetite is because jaw frame's secondary assembly, also be assembled on jaw frame expandes support or human whole body model promptly.
When the utility model is used, the muscle layer is laid on the inner surface of the jaw frame main body, and the teeth are arranged in the tooth mounting grooves on the jaw frame main body one by one. Then arrange the bolt locating rack in the locating rack mounting groove, because the cooperation location of assembly arch and assembly recess, the screw on the bolt locating rack can both the one-to-one with the screw of every tooth bottom, use the bolt to penetrate the bolt mounting hole to screw up in the tooth bottom, play the effect spacing alone to every tooth. Thus, the separate jaw frame, or respectively the separate upper or lower jaw frame, is assembled.
The utility model has the advantages that: the utility model discloses simple structure, the assembly is nimble convenient, and the secondary is moulded plastics the muscle layer that forms and also very big reduction the holistic manufacturing degree of difficulty of equipment, has improved the fidelity of equipment, and ingenious cooperation between each part is the main beneficial effect of this equipment, and the part that corresponds the setting has improved the assembly precision, also can be faster, simpler assembly.

Detailed Description
Referring to fig. 1, 2 and 3, the jaw frame model convenient for positioning and assembling of the present invention includes a jaw frame main body 1, a bolt positioning frame 3, a muscle layer 7 and teeth.
The jaw frame main body 1 is formed by injection molding in a mode of imitating a jaw bone of a human body, and in detail, the jaw bone, a dental arch and a jaw part of the human body are integrally formed by injection molding. The jaw frame main body 1 is provided with a tooth mounting groove at a position corresponding to a dental arch. The central position of the outer surface of the jaw frame is integrally provided with an assembly boss 2, and the central position of the assembly boss 2 is in a screw hole form and is used for further mounting the whole device on a jaw frame unfolding bracket or a human body shaping model.
The inner surface of the jaw frame main body 1 is provided with a muscle layer 7, and the muscle layer 7 can be applied to the inner surface of the jaw frame main body 1 in a secondary injection molding mode.
The outside of jaw frame main part 1 corresponds human dental arch position, is equipped with locating rack mounting groove 4, install bolt locating rack 3 in the locating rack mounting groove 4.
