Description

Technical Field

[0001] The utility model belongs to the technical field of oral models, and more specifically, particularly relates to a vibration hammer for oral models. Background Technique

[0002] Oral models are mainly used as working models for fabricating various prostheses in clinical practice, and can also be used as research and recording models. The materials used for pouring models are called model materials, and common model materials include plaster of Paris, high-strength dental stone, artificial stone, low-melting alloy, phosphate, and silicone rubber, etc. The manufacturing method of oral models is to mix plaster powder and water in a powder-to-water ratio of 2:1, stir evenly with a mixing knife, and then inject it into the impression after vibrating with a vibrator or by hand vibration to complete the production of the model. The clinical significance of oral models lies in being able to display the patient's oral conditions through an external model, which is more convenient for clinicians to formulate treatment plans.

[0003] Based on the above, the inventor found the following problems: The existing porcelain stacking vibration hammer for dental technicians is adapted from an ordinary hammer, not a special tool. The hammer handle and the hammer head are connected by a hard material, and there is excessive vibration during knocking, without any buffer in the middle, which poses a potential risk of injury to the operator's hand and a risk of damage to the operating model and stacked porcelain powder.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a vibration hammer for oral models is provided with the expectation of achieving a more practical value. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a vibration hammer for oral models to solve the problem that the existing hammer handle and hammer head are connected by a hard material, with excessive vibration during knocking and no buffer in the middle.

[0006] The purpose and effect of a vibration hammer for oral models of the utility model are achieved by the following specific technical means:

[0007] A vibration hammer for oral models includes a hammer handle and a hammer head. The hammer handle and the hammer head are connected by an elastic connecting piece. One end of the hammer handle is provided with a mounting hole, and a movable rod is installed inside the mounting hole. The movable rod is connected to the lower end of the elastic connecting piece.

[0008] Further, a movable groove is provided on the side surface of one end of the hammer handle, and a rotating part is rotatably installed inside the movable groove. The lower part of the movable rod is located inside the rotating part.

[0009] Further, a rotating ring is installed at one end of the rotating part. Internal threads are provided on the inner side of the rotating ring, and external threads adapted to the internal threads are provided on the movable rod.

[0010] Further, the diameter of the movable rod is adapted to the diameter of the mounting hole, and the diameter of the elastic connecting member is smaller than the inner diameter of the rotating ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] When the whole of the utility model is struck, through the elastic connecting member between the hammer handle and the hammer head, the force received by the hammer head can be buffered. At this time, the vibration of the hammer handle will be reduced, the shaping and compactness of the porcelain powder will be better. At the same time, through the buffering of the elastic connecting member, the damage to the model can be reduced, and the injury probability of the human hand can be lowered.

[0013] In the utility model, by rotating the rotating member, the rotating member can drive the rotating ring to rotate. When the rotating ring rotates, it can drive the movable rod to move up or down through the cooperation of the internal thread and the external thread. When the movable rod moves down, it can drive the elastic connecting member to move down. When the elastic connecting member moves down, it can gradually enter the inside of the rotating member, shortening the exposed length of the elastic connecting member, and the vibration amplitude of the elastic connecting member can be adjusted.
