[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: See Figures 1 to 8According to an embodiment of the present utility model, a technical solution is provided: a denture scanner for facilitating the positioning of dentures, comprising a scanning camera 1, and a box body 2, which has an opening 3, a drawer plate 4 movably provided in the box body 2, and the opening 3 is selectively covered by a cover plate 5; a denture body 6, which comprises a denture lower mold 8 and a denture upper mold 7 provided on the top thereof, the denture body 6 is provided on the drawer plate 4, the scanning camera 1 is provided in the box body 2, and is arranged toward the denture body 6; and a limiting mechanism 9, which is provided on the drawer plate 4, and selectively fixes the denture body 6 relative to the drawer plate 4 to limit or allow the denture body 6 to move relative to the drawer plate 4.

[0029] The denture scanner that is convenient for limiting the position of dentures adopts the above-mentioned structure. When the user needs to limit the denture body 6 on the drawer plate 4, first, the denture body 6 is placed on the drawer plate 4, and then, the denture body 6 and the drawer plate 4 are relatively fixed by the limiting mechanism 9, so that the limiting of the denture body 6 is completed. At this time, the scanning camera 1 can be used to scan the denture body 6. When the user needs to remove the denture body 6 from the drawer plate 4, similarly, the relative fixed state between the denture body 6 and the drawer plate 4 is released by the limiting mechanism 9, and the denture body 6 can be removed from the drawer plate 4, thereby improving the disassembly and assembly efficiency of the denture body 6 during the limiting process.

[0030] In this embodiment, the limiting mechanism 9 includes a limiting plate 11, an abutment block 12, a guide rod 13 and a spring 14; the bottom of the denture lower mold 8 protrudes downward to form a limiting portion 17, and the limiting plate 11 is provided with a limiting groove 18 suitable for the limiting portion 17 to be movably inserted, and the limiting plate 11 is arranged on the withdrawal plate 4; an abutment groove 16 is defined in the limiting plate 11, and the abutment groove 16 is connected to the limiting groove 18; the guide rod 13 is arranged in the abutment groove 16, and the abutment block 12 is movably arranged in the abutment groove 16 and is movably penetrated by the guide rod 13, and the spring 14 is sleeved on the guide rod 13 and elastically abuts the abutment block 12, and the top of the abutment block 12 is configured to be an inclined surface; when the user needs to limit the denture body 6 on the withdrawal plate 4, first, the limiting portion 17 of the denture lower mold 8 is inserted into the limiting groove on the limiting plate 11 When the retaining member 12 is completely immersed in the abutment groove 16, the spring on the guide rod 13 will elastically abut the retaining member 12, so that the retaining member 12 generates an abutting force on the retaining member 17 to limit the upward movement of the retaining member 17, thereby completing the abutment fixation of the denture lower mold 8 by a friction force. At this time, the user scans the denture upper mold 7 through the scanning camera 1. When the scanning operation is completed, the denture lower mold 8 is pulled out from the limiting groove 18 to disengage the limiting portion 17 from the limiting groove 18, and the denture body 6 can be removed from the draw plate 4, thereby improving the disassembly and assembly efficiency of the denture body 6 during the limiting process.

[0031] In this embodiment, a lifting block 19 is provided on the peripheral side wall of the denture lower mold 8; when the user lifts the denture lower mold 8, the lifting block 19 will provide the user with a fulcrum for lifting the denture lower mold 8, so that the user can lift the denture lower mold 8 conveniently.

[0032] In this embodiment, a locking mechanism 10 is provided on the cover plate 5. The locking mechanism 10 is used to selectively fix the cover plate 5 relative to the box body 2 when the cover plate 5 exposes the opening 3, so as to limit or allow the cover plate 5 to move relative to the box body 2; when the user opens the cover plate 5 to expose the opening 3, the cover plate 5 is fixed relative to the box body 2 through the locking mechanism 10, so that the user can pull out the withdrawal plate 4 without having to continuously support the cover plate 5, which makes it easier for the user to limit the denture body 6 on the withdrawal plate 4.

[0033] In this embodiment, the locking mechanism 10 includes a fixing block 20, a fixing block 21, a locking column 24, a limiting ring 22 and a spring 2 15; the fixing block 20 is fixed on the cover 5, and the fixing block 21 is fixed to the top of the fixing block 20; the locking column 24 is movable through the fixing block 21 and the box body 2, the limiting ring 22 is sleeved on the locking column 24, and is arranged between the fixing block 21 and the box body 2, and the spring 2 15 is sleeved on the locking column 24 and elastically abuts the limiting ring 22; when the user needs to fix the cover 5 relative to the box body 2, the cover 5 is first opened to expose the opening 3 of the box body 2. At this time, the locking column 24 is pulled and then released to allow the locking column 24 to move through the fixing block 21 and the box body 2 to fix the cover 5 relative to the box body 2, which is convenient for the user to perform the next step of operation.

[0034] In this embodiment, there are several friction-increasing grooves 23 spaced along the circumference of the locking column 24 at one end facing away from the box body 2; when the user pulls the locking column 24, the friction-increasing grooves 23 located on the locking column 24 will increase the friction between the locking column 24 and the user's fingers, making it easier for the user to pull the locking column 24.

[0035] Working principle: When the user needs to limit the denture body 6 on the draw plate 4, first, insert the limiting portion 17 of the denture lower mold 8 into the limiting groove 18 on the limiting plate 11. During this process, the limiting portion 17 will contact the inclined surface of the abutment block 12, thereby continuously pressing the abutment block 12 into the abutment groove 16. Then, when the abutment block 12 is completely immersed in the abutment groove 16, the spring on the guide rod 13 will elastically abut the abutment block 12, so that the abutment The block 12 generates an abutting force on the limiting portion 17 to limit the upward movement of the limiting portion 17, thereby completing the abutting fixation of the denture lower mold 8 with a friction force. At this time, the user scans the denture upper mold 7 through the scanning camera 1. When the scanning operation is completed, the denture lower mold 8 is pulled out from the limiting groove 18 to separate the limiting portion 17 from the limiting groove 18, and the denture body 6 can be removed from the draw plate 4, thereby improving the denture body 6 in the limiting groove. When the user pulls the locking post 24, the friction groove 23 on the locking post 24 will increase the friction between the locking post 24 and the user's finger, so that the user can pull the locking post 24.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
