Description

Technical Field

[0001] The utility model relates to the technical field of denture devices, in particular to a fixer for movable dentures. Background Art

[0002] Removable dentures are a common restoration method in the field of oral rehabilitation, usually used to replace missing teeth and restore patients' chewing and aesthetic functions. Traditional removable dentures need the support of a retainer to maintain their stability during use, which includes a denture bridge and a denture.

[0003] However, traditional retainers have an important drawback, that is, the denture body and the denture bridge are usually fixed together and cannot be removed separately. This leads to a problem that if one of the parts is damaged or needs to be replaced, the entire denture needs to be remade or replaced, which increases the patient's maintenance cost and time cost, and also reduces the maintainability and flexibility of the denture. Utility Model Content

[0004] 1. Technical issues

[0005] The utility model provides a fixer for a removable denture, aiming to solve the defects of the above-mentioned traditional fixer, so that the dentures on the denture bridge can be fixed independently, which is convenient for individual replacement and maintenance, and improves the operability and economy of the removable denture.

[0006] (II) Technical content

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a fixture for a removable denture, comprising a denture bridge and a denture, a plurality of dentures equidistantly distributed are detachably fixedly connected on the denture bridge, a plurality of mounting cavities are provided on the denture bridge, a limiting steel ball is movably inserted into the inner side wall of each mounting cavity, a spring reset mechanism is provided at one end of the limiting steel ball extending into the interior of the denture bridge, the denture comprises a denture body and a mounting base fixedly arranged at the bottom of the denture body, the mounting base is matched and inserted in the mounting cavity, and a limiting circular groove is provided on the side surface of the mounting base corresponding to the position of the limiting steel ball.

[0008] Furthermore, the spring reset mechanism is arranged in the cavity inside the denture bridge, and a limiting plate is fixedly provided at one end of the limiting steel ball extending into the cavity, and a spring is arranged between the limiting plate and the bottom surface of the cavity.

[0009] Furthermore, two groups of limiting steel balls are arranged inside each of the installation cavities, and the two groups of limiting steel balls are symmetrically distributed.

[0010] Furthermore, a sealing slot is provided on the outer side of the upper end of each installation cavity, and a convex ring is fixedly provided on the bottom edge of the denture body, and the convex ring is matched and plugged into the sealing slot.

[0011] (III) Technical Effect

[0012] Compared with the prior art, the utility model has the following advantages: the design of the movable denture fixture allows the dentures on the denture bridge to be independently fixed and removed, which is convenient for individual replacement and maintenance. Patients no longer need to replace the dentures as a whole, but can repair individual dentures, saving time and cost. The new fixture design increases the flexibility of the dentures, making them more in line with individual oral needs. Individual dentures can be adjusted or replaced as needed, which improves the adaptability and comfort of the dentures. The dentures are fixed by limiting steel balls and spring reset mechanisms, and the dentures are highly stable and easy to remove. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "center", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction structure and operation. Therefore, they should not be understood as limitations on the present invention.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "installed", "connected", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] Combined with Figure 1 To Attachment Figure 5 A fixture for a removable denture comprises a denture bridge 1 and a denture 2, wherein a plurality of dentures 2 are detachably fixedly connected to the denture bridge 1 and are distributed at equal distances, wherein the denture bridge 1 is provided with a plurality of mounting cavities 3, wherein a limiting steel ball 4 is movably inserted into the inner side wall of each mounting cavity 3, wherein a spring reset mechanism is provided at one end of the limiting steel ball 4 extending into the interior of the denture bridge 1, wherein the denture 2 comprises a denture body 201 and a mounting base 202 fixedly arranged at the bottom of the denture body 201, wherein the mounting base 202 is matched and inserted into the mounting cavity 3, and a limiting circular groove 203 is provided on the side surface of the mounting base 202 corresponding to the position of the limiting steel ball 4.

[0024] Reference Figure 5 In this embodiment, the spring return mechanism is arranged in the cavity 5 inside the denture bridge 1, and a limiting plate 6 is fixed to one end of the limiting steel ball 4 extending into the cavity 5. A spring 7 is arranged between the limiting plate 6 and the bottom surface of the cavity 5. Two groups of limiting steel balls 4 are arranged inside each of the installation cavities 3, and the two groups of limiting steel balls 4 are symmetrically distributed.

[0025] Example 2

[0026] Compared with Example 1, on the basis of Example 1, a sealing slot 8 is provided on the outer side of the upper end of each installation cavity 3, and a convex ring 204 is fixedly provided on the bottom edge of the denture body 201, and the convex ring 204 is matched and plugged with the sealing slot 8.

[0027] The matching plug-in design of the convex ring and the sealing slot can effectively enhance the sealing between the installation cavity and the denture body. This helps prevent food residues or bacteria from penetrating into the installation cavity, reduces the accumulation of foreign matter in the oral cavity, and improves oral hygiene. The matching plug-in design of the convex ring and the sealing slot can increase the connection stability between the installation cavity and the denture, prevent the denture from loosening or falling off during use, and improve the stability and comfort of the denture.

[0028] The specific working principle of the utility model: when the utility model is in use, each denture 2 is plugged and fixed in the installation cavity 3. During the plugging process, the installation base 202 is inserted into the installation cavity 3, and the limiting steel ball 4 is stuck in the limiting circular groove 203. At the same time, the convex ring 204 is inserted into the sealing slot 8. At this point, the installation and fixation of the denture is completed. When a single denture needs to be removed, it only needs to be pulled outward. The cooperation of the limiting steel ball 4 and the limiting circular groove 203 makes the installation and removal of the denture very convenient.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
