Technical Field

[0001] This utility model relates to the field of jaw frame technology, and in particular to a jaw frame with adjustable opening and closing degree. Background Technology

[0002] An articulator, also known as an occlusal appliance, is an instrument that mimics the human upper and lower jaws and temporomandibular joint, fixes the upper and lower jaw models, and simulates jaw movements to a certain extent. In the fields of prosthodontics and orthodontics, the articulator is an important auxiliary tool that helps dentists and technicians to more accurately fabricate restorations, orthodontic appliances, and ensure that the restorations or appliances have a good occlusal relationship and function in the patient's mouth.

[0003] In the existing technology, the two fixing plates on the jaw frame are assembled and installed by magnetic attraction without any other auxiliary installation structure. When the fixing plates are installed by magnetic attraction, they are prone to tilting, which causes the installation position of the lower fixing plate to shift. Therefore, a jaw frame with adjustable opening degree is proposed. Utility Model Content

[0012] This design presents an adjustable jaw frame. It comprises a fixed block, a fixed rod, a connecting piece, a locking block, a screw, and a pressing block. The fixed block engages with locking holes on the upper and lower supports. Rotating the screw moves one end inwards towards the fixed block, causing the pressing block to move within the fixed block. The tapered surface at the top of the pressing block abuts against the locking block, causing it to move further inwards and engage with a rectangular insertion hole within the locking hole. After the pressing block and locking block engage, the connecting piece slides on the fixed rod, pressing against the first spring. To remove the fixed plate, the two screws are rotated in the opposite direction to separate the pressing block from the locking block. The spring force of the first spring causes the connecting piece to reset on the fixed rod, retracting the locking block back into the fixed block. This design, through the cooperation of the fixed block and locking block, ensures the two fixed plates are securely mounted on the upper and lower supports, preventing positional shifts and facilitating removal.

[0019] Please see Figures 1-4 This utility model provides a jaw frame technology solution with adjustable opening and closing degree, including a lower support 1 and an upper support 4. The lower support 1 is symmetrically equipped with columns 2, and the top of each of the two columns 2 is equipped with a connecting plate 3. One end of the upper support 4 is provided with a guide needle seat 8, and the guide needle seat 8 is provided with a condylar guide needle 9. The top and one side of the guide needle seat 8 are provided with adjustment knobs.

[0020] Both the lower support 1 and the upper support 4 are equipped with fixing plates 10, and fixing blocks 11 are installed on each of the two fixing plates 10. The two fixing plates 10 are respectively arranged opposite to each other on the lower support 1 and the upper support 4. Multiple fixing rods 13 are installed in a circular array at the top of the interior of each fixing block 11. A connecting piece 14 is slidably connected to each fixing rod 13. A locking block 16 is installed at the bottom of each connecting piece 14. The bottom of each of the two fixing blocks 11 is threadedly connected to a screw 12, and a pressing block is installed at the top of each of the two screws 12. 18. Each fixing rod 13 is fitted with a first spring 17, and a baffle 15 is installed at one end of each fixing rod 13. One end of each first spring 17 abuts against the inner wall of the fixing block 11, and the other end of each first spring 17 abuts against the connecting piece 14. The top of the pressing block 18 is flat-topped and conical, which facilitates the pressing block 18 abutting against the locking block 16 and pushing the locking block 16 out of the interior of the fixing block 11. Both fixing blocks 11 are provided with a circular array of sliding grooves that are compatible with the locking block 16. (The fixing block 11 and the locking block 16 are as follows) Figure 2As shown), the fixing block 11 is placed in the insertion hole on the upper bracket 1 or the lower bracket 4. The screw 12 is rotated, and one end of the screw 12 moves toward the inside of the fixing block 11, which drives the pressing block 18 to move. The pressing block 18 abuts against the locking block 16, pushing the locking block 16 to move outward. At this time, the connecting piece 14 slides on the fixing rod 13 to press the first spring 17. The locking block 16 moves outward and inserts into the rectangular insertion hole. The fixing plate 10 is installed on the upper bracket 1 or the lower bracket 4.

[0021] Both the lower bracket 1 and the upper bracket 4 are provided with locking holes adapted to the fixing block 11. A circular array of rectangular insertion holes adapted to the locking block 16 is arranged within these locking holes. Connecting seats 26 are rotatably connected to both connecting plates 3. Connecting pieces 19 are installed on both connecting seats 26. Connecting rings 20 are rotatably connected to both connecting pieces 19. Connecting plates 5 are symmetrically installed at the bottom of the upper bracket 4. Connecting cylinders 6 are installed between the two connecting plates 5. Inserting rods 7 are symmetrically arranged on the connecting cylinders 6. One end of each inserting rod 7 extends into the interior of the connecting cylinder 6 and is fitted with a disc 23. A sliding rod 24 is installed at one end of each disc 23. A second spring 25 is sleeved on each sliding rod 24. Inserting holes adapted to the inserting rods 7 are rotatably arranged on both connecting rings 20. Both connecting seats 26 are equipped with limit rods 21. One end of each limit rod 21 extends to the outside of the connecting plate 3 and is threaded with a locking block 22. When the two insert rods 7 are moved closer to each other on the connecting cylinder 6, one end of the insert rod 7 slides toward the inner wall of the connecting cylinder 6. The disc 23 compresses the second spring 25, aligning the insert rod 7 with the connecting ring 20 on the connecting piece 19. When the insert rod 7 is released, the elastic force of the second spring 25 causes the insert rod 7 to move outward and reset. The other end of the insert rod 7 passes through the connecting ring 20 and is inserted. The upper bracket 4 is assembled at the top of the column 2. The locking blocks 22 on the two limit rods 21 are rotated and pressed tightly against the outer wall of the connecting plate 3, limiting the connecting seat 26 so that it cannot be rotated left or right. When the locking blocks 22 are released and separated from the connecting plate 3, the connecting seat 26 can be rotated slightly.

[0022] The working principle of this utility model is as follows: two insert rods 7 are moved closer to each other on the connecting cylinder 6, one end of the insert rod 7 slides towards the inner wall of the connecting cylinder 6, the disc 23 squeezes the second spring 25, and the insert rod 7 aligns with the connecting ring 20 on the connecting piece 19. The insert rod 7 is released, and the elastic force of the second spring 25 causes the insert rod 7 to move outward and reset. The other end of the insert rod 7 passes through the connecting ring 20 and is inserted. The upper bracket 4 is assembled on the top of the column 2. The fixing block 11 is placed in the insertion hole on the upper bracket 1 and the lower bracket 4 in sequence. The screw 12 is rotated, and one end of the screw 12 moves towards the inside of the fixing block 11, driving the pressing block 18 to move. The pressing block 18 abuts against the locking block 16 and pushes the locking block 16 to move outward. At this time, the connecting piece 14 slides on the fixing rod 13 to squeeze the first spring 17. The locking block 16 moves outward and inserts into the rectangular insertion hole. The fixing disc 10 is installed on the upper bracket 1 and the lower bracket 4.
