DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figure 1-Figure 4 The present invention provides the following technical solutions: In order to solve the problem that the fixed mold denture is difficult to maintain a firm state during operation and difficult to accurately replicate the patient's oral structure, a self-locking mechanism is disclosed:

[0030] The present invention comprises a base frame 1, a transmission mechanism 2 being connected to the side of the base frame 1, and a mold tooth 3 being rotatably connected to the inner side of the base frame 1 through the transmission mechanism 2. The transmission mechanism 2 comprises a first gear, a second gear and a rotating rod. A rotating groove 101 is provided on the left side of the base frame 1, and a self-locking mechanism for closing the mold tooth 3 is provided inside the rotating groove 101. The self-locking mechanism comprises a rotating block 102, and the rotating block 102 rotates through the rotating groove 101. A torsion spring 103 is connected between the rotating block 102 and the rotating groove 101. A rotating rod 104 is fixed to the end of the rotating block 102, a connecting block 105 is fixed to the bottom of the rotating rod 104, and a ratchet 106 is fixed to the surface of the rotating rod. An external block 107 is connected to the right side of the base frame 1, and an extrusion mechanism that improves the stability of the mold tooth 3 is provided inside the external block 107. When the fixed mold is closed, the transmission mechanism 2 is operated, and the first gear and the second gear can be driven to rotate through the rotating rod of the transmission mechanism 2. When the mold teeth 3 are closed, the ratchet 106 will rotate, and the torsion spring 103 will drive the mold teeth 3 to close. When the mold teeth 3 are closed, the ratchet 106 will rotate to the specified position. At this time, the torsion spring 103 can drive the rotating block 102 to reset through its own torque. When the rotating block 102 is reset, the rotating rod 104 can be driven to reset when the rotating block 102 is reset. When the rotating block 102 is reset, the rotating rod 104 can be stuck between the oblique teeth of the ratchet 106. The oblique tooth characteristics can prevent the ratchet 106 from rotating, thereby realizing the positioning of the transmission mechanism 2, thereby realizing the closed self-locking function of the denture fixing mold.

[0031] Example 2:

[0032] like Figure 2 and Figure 5The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the denture of the fixed mold may move or loosen during operation, an extrusion mechanism is disclosed:

[0033] The extrusion mechanism includes a sliding groove 108, which is opened on the side of the external block 107. A sliding block 109 slides through the sliding groove 108. A first pressing plate 110 is fixed to the left end of the sliding block 109, and a second pressing plate 111 is fixed to the side of the external block 107. A threaded rod 112 is connected to the right end of the sliding block 109, and a nut 113 is threadedly connected to the surface of the threaded rod 112. When the self-locking function of the fixed mold is used, the mold teeth 3 will be merged. Moving the external block 107 can drive the first pressing plate 110 and the second pressing plate 111 to move. When the second pressing plate 111 moves to the bottom of the mold teeth 3, the first pressing plate 110 can move to the top of the mold teeth 3. Pressing the first pressing plate 110 can drive the sliding The movable block 109 moves, and the sliding block 109 can slide through the sliding groove 108 when it moves. When the first pressing plate 110 slides to the upper surface of the mold tooth 3, the mold tooth 3 can be squeezed through the second pressing plate 111. When the mold tooth 3 is squeezed, the nut 113 is moved to the end of the threaded rod 112 for rotation. When the nut 113 rotates, it can slide through the threaded rod 112. When the nut 113 slides to the side of the external block 107, it can be squeezed and positioned. When the threaded rod 112 is positioned, it can drive the first pressing plate 110 to position. After the first pressing plate 110 is positioned, it can drive the mold tooth 3 to position, thereby preventing the mold tooth 3 from loosening during operation and processing, further improving the accuracy and quality of the denture.

[0036] The right side of the base frame 1 is also provided with a locking mechanism for disassembling the external block 107. The locking mechanism includes a telescopic slot 114. The telescopic slot 114 is opened on the right side of the base frame 1. A spring 115 is connected to the inside of the telescopic slot 114. The end of the spring 115 is connected to a telescopic block 116. The telescopic block 116 slides through the telescopic slot 114. A locking block 117 is fixed to the right end of the telescopic block 116. A locking slot 118 is opened on the inside of the external block 107. The locking slot 118 is locked with the locking block 117. An insert block 119 is fixed to the side of the external block 107. A positioning slot 120 is opened on the side of the base frame 1. When the extrusion mechanism is not in use, the telescopic block 116 can be pushed through the telescopic slot 114. When the external block 107 is pulled, the plug-in block 119 can be driven to move, and the plug-in block 119 can slide through the positioning groove 120 when the external block 107 moves. When the external block 107 is pulled, the plug-in block 119 can slide through the positioning groove 120 when the external block 107 moves.
