Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The multi-directional positioning dental crown device shown in the accompanying figures 1-4 comprises a fixed plate 1, wherein a groove 2 is formed in the bottom surface of the fixed plate 1, and a positioning mechanism is arranged in the groove 2;

The positioning mechanism comprises a threaded hole 3, the threaded hole 3 is formed in the top surface of the inner wall of the groove 2, a first threaded rod 4 is arranged in the threaded hole 3, a first knob 5 is arranged at the top of the first threaded rod 4, a crown connecting sleeve 6 is arranged at the bottom of the first threaded rod 4, a bearing 7 is arranged between the first threaded rod 4 and the crown connecting sleeve 6, an inner cavity 8 is formed in the fixing plate 1, a second threaded rod 9 is arranged in the inner cavity 8, a threaded sleeve 12 is arranged outside the second threaded rod 9, a connecting sliding rod 13 is fixedly connected to the bottom of the threaded sleeve 12, and a movable clamping plate 14 is fixedly arranged at the bottom of the connecting sliding rod 13.

As shown in fig. 1-3, the bottom surface of the fixed plate 1 is provided with a through chute 11, a connecting slide bar 13 is slidably connected with the through chute 11, the connecting slide bar 13 slides in the event to prevent the movable clamping plate 14 and the threaded sleeve 12 from rotating, one end of the second threaded rod 9 penetrates through the fixed plate 1 and extends to the outer side of the fixed plate 1, one end of the second threaded rod 9 is provided with a second knob 10, the outer surface of the second threaded rod 9 is symmetrically provided with two groups of threads, the second threaded rod 9 is in threaded connection with the threaded sleeve 12, and the second threaded rod 9 is conveniently driven to rotate by rotating the second knob 10, so that the two threaded sleeves 12 are mutually close to each other.

As shown in fig. 1 to 4, the first threaded rod 4 is in threaded connection with the threaded hole 3, the top of the first threaded rod 4 penetrates through the fixing plate 1 and extends to the top of the fixing plate 1, and the first threaded rod 4 is moved inside the threaded hole 3 by rotating the first threaded rod 4.

As shown in fig. 1 and 2, limiting slide bars 16 are arranged on two sides of the dental crown connecting sleeve 6, limiting slide grooves 17 are formed on two side surfaces of the inner wall of the groove 2, and the limiting slide bars 16 are in sliding connection with the limiting slide grooves 17 to limit the dental crown connecting sleeve 6, so that the dental crown connecting sleeve 6 can only vertically lift.

As shown in fig. 1-4, the number of the movable clamping plates 14 is multiple, and a plurality of friction blocks 15 are installed on one side of each of the movable clamping plates 14, so that friction force between the movable clamping plates 14 and teeth is improved, fixing effect is improved, and the device is stable and cannot move to ensure positioning accuracy.

The working principle of the utility model is as follows: in the using process of the multi-directional positioning dental crown device provided by the utility model, firstly, the fixed plate 1 is placed above the teeth, the positions of the artificial dental crowns are required to be sleeved and aligned with the grooves 2, one side of the teeth are positioned between the two movable clamping plates 14, the second knob 10 is rotated, so that the second knob 10 drives the second threaded rod 9 to rotate, meanwhile, as the second threaded rod 9 is in threaded connection with the threaded sleeve 12, two groups of threads are symmetrically arranged on the outer surface of the second threaded rod 9, the two threaded sleeves 12 are driven to move close to each other through the rotation of the second threaded rod 9, so that the connecting slide rod 13 slides on the surface of the penetrating slide groove 11, the two movable clamping plates 14 are driven to move close to each other through the connecting slide rod 13, the normal teeth are clamped and fixed through the movable clamping plates 14, the fixing effect of the whole device is improved, then the other two movable clamping plates 14 are rotated to clamp the other side of the teeth, the fixing effect of the whole device is completed, the threaded rod 4 is driven to rotate through the first knob 5, meanwhile, and the threaded rod 4 is connected with the threaded rod 4 through the rotation of the first knob 5, and the threaded rod 4 is connected with the threaded rod 4 through the threads, and the threaded rod 4 is driven to rotate the threaded rod 6, so that the artificial dental crown is positioned in the process is convenient to move the dental crown 6, and the artificial dental crown is positioned in the process.

Finally: the above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model. Accordingly, it is intended that all equivalent modifications and variations of the utility model be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
