Description

Technical Field

[0001] This utility model relates to the field of oral medical auxiliary tools, specifically, a disposable mouth mirror anti-fog and waterproof film fixing device. Background Technology

[0002] Disposable oral mirrors are commonly used medical instruments in dental treatment. They help dentists observe areas in the oral cavity that are difficult to see directly by reflecting light and images. However, after the mirror comes into contact with the oral environment, the surface is prone to fogging due to temperature differences, resulting in blurred reflected images. To solve this problem, an anti-fog and waterproof film needs to be attached to the surface of the oral mirror. The anti-fog and waterproof film reduces the need for dentists to repeatedly wipe the mirror due to fogging.

[0003] Currently, dental clinics mostly use simple clips or slots to fix mouth mirrors. Chinese patent CN203001147U discloses a multifunctional dental forceps, which includes a gripping end and a handle. The handle is a hollow groove type. One end of the handle is hinged to the gripping end. The end of the gripping end is provided with a removable protective sleeve. The gripping end can be folded and stored in the handle through the hinge. The other end of the handle is provided with a mouth mirror. The gripping end and the handle are engraved with scales. The shape of the removable protective sleeve matches the end of the gripping end.

[0004] This simple clamping method cannot effectively cope with external forces such as vibration and touch during the operation. The mouth mirror is very easy to shift or even fall off. In addition, impurities such as air bubbles and water stains generated during the film application process require additional tools to clean, which prolongs the treatment time and reduces the doctor's treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a disposable mouth mirror anti-fog and waterproof film fixing device, which aims to improve the problems of unstable film clamping and the need for additional tools for cleaning in the prior art.

[0006] The purpose of this utility model is achieved as follows: A disposable mouth mirror anti-fog and waterproof film fixing device, comprising:

[0007] frame;

[0008] A clamping mechanism is mounted on the frame and clamps the mouthpiece when the anti-fog and waterproof membrane is attached to the mirror surface.

[0009] A universal adjusting arm is connected to the clamping mechanism. At the end of the universal adjusting arm is a scraper for pressing the anti-fog and waterproof membrane onto the surface of the mouth lens. The two ends of the scraper are rounded to smoothly contact the anti-fog and waterproof membrane. The universal adjusting arm itself can be bent at will to adjust the working position of the scraper at will.

[0010] Furthermore, a support frame is fixedly connected to the frame, and the support frame supports the handle of the mouth mirror when the anti-fog and waterproof membrane is attached to the mirror surface.

[0011] Furthermore, the support surface of the support frame is designed as a concave arc surface.

[0012] Furthermore, the rack includes:

[0013] Base;

[0014] Side plate one and side plate two are fixedly connected to the left and right sides of the base, respectively.

[0015] Furthermore, the clamping mechanism includes:

[0016] Clamping seat one and clamping seat two are slidably connected to the base;

[0017] A bidirectional screw, one end of which rotatably passes through side plate one and is fixedly connected to an adjustment knob located outside side plate one; the other end of which rotatably connects to side plate two.

[0018] The bidirectional screw has two threaded portions with opposite directions of rotation: a first threaded portion and a second threaded portion. The first threaded portion passes through a clamping seat and is threadedly engaged with the clamping seat. The second threaded portion passes through a clamping seat and is threadedly engaged with the clamping seat.

[0019] Furthermore, both clamping seat one and clamping seat two are provided with triangular grooves on their upper sides. The inner wall of the triangular grooves is provided with an anti-slip textured surface. The top of the triangular grooves is rounded. From a top view, the triangular grooves are triangular. The triangular grooves of clamping seat one and clamping seat two are arranged opposite to each other and abut against the outer peripheral edge of the mouthpiece when clamping the mouthpiece.

[0020] Furthermore, the base is fixed with a guide rail for guiding the clamping direction, and the clamping seat one and clamping seat two slide in cooperation with the guide rail along the clamping direction.

[0021] Furthermore, the end of the bidirectional screw facing the second side plate is coaxially provided with a circular connecting hole, and a circular groove is provided on the inner side of the second side plate, and a cylindrical fixing pin is coaxially fixed in the circular groove. The end of the bidirectional screw is relatively rotatably inserted into the inner circular groove of the second side plate, and the fixing pin is relatively rotatably inserted into the connecting hole of the bidirectional screw.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This utility model guides the sliding of clamping seat one and clamping seat two through guide rails, and drives the two to move relative to each other with the help of bidirectional screws, so that the top triangular grooves are precisely aligned to clamp the mouth lens. The anti-slip texture on the inner wall of the triangular groove increases the friction, and the rounded corners at the top facilitate the picking and putting in the mouth lens. It can effectively resist vibration and touch during operation, prevent the mouth lens from shifting or falling off, and ensure the stability of the film application process.

[0024] 2. The air bubbles and water stains generated during the film application process can be quickly cleaned by adjusting the universal adjustment arm and using a scraper, without having to put down the tool to switch, reducing the number of operation steps and making up for the shortcomings of existing products that are limited in function and inconvenient to use.

Detailed Implementation

[0031] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figure 1-4 As shown, a disposable mouth mirror anti-fog and waterproof film fixing device includes:

[0033] frame;

[0034] The clamping mechanism is installed on the frame and clamps the mouth mirror 2 when the anti-fog and waterproof membrane is attached to the mirror surface of the mouth mirror 2.

[0035] A universal adjusting arm 9 is connected to the clamping mechanism. At the end of the universal adjusting arm 9 is a scraper 10 for pressing the anti-fog and waterproof membrane onto the mirror surface of the mouth mirror 2. The two ends of the scraper 10 are rounded to smoothly contact the anti-fog and waterproof membrane. The universal adjusting arm 9 itself can be bent at will to adjust the working position of the scraper 10 at will. Since the two ends of the scraper 10 are designed to be rounded, the scraper 10 can scrape out the air bubbles between the circular mouth mirror 2 and the membrane to the greatest extent.

[0036] As a preferred option, a support frame 8 is fixedly connected to the frame. When the anti-fog and waterproof membrane is attached to the mirror surface of the mouth mirror 2, the support frame 8 supports the handle of the mouth mirror 2.

[0037] As a preferred embodiment, the support surface of the support frame 8 is set as a concave arc surface, and the handle of the mouth mirror 2 is in contact with the support surface of the support frame 8 to provide additional support for the mouth mirror 2.

[0038] As a preferred embodiment, the rack includes:

[0039] Base 1;

[0040] Side plate 12 and side plate 23 are fixedly connected to the left and right sides of the base 1, respectively.

[0041] In addition, the clamping mechanism includes:

[0042] Clamping seat 1 3 and clamping seat 2 4 are slidably connected to base 1.

[0043] A bidirectional screw 5, one end of which is rotatably connected through side plate 12 and fixedly connected to an adjustment knob 7 located outside side plate 12; the other end of the bidirectional screw 5 is rotatably connected to side plate 2 13.

[0044] The bidirectional screw 5 has two threaded portions with opposite directions of rotation: a first threaded portion and a second threaded portion. The first threaded portion passes through the clamping seat 3 and is threadedly engaged with the clamping seat 3. The second threaded portion passes through the clamping seat 4 and is threadedly engaged with the clamping seat 4.

[0045] The adjustment knob 7 is rotatably connected to one side surface of the side plate 12, and its surface has anti-slip textures for easy adjustment by the operator. A through hole is opened in the center of the side plate 12, through which the bidirectional screw 5 passes and forms a rotatable connection with the side plate 12, further ensuring the stability of the screw during rotation.

[0046] The base 1, clamping seat 1 3 and clamping seat 2 4 are all made of carbon fiber composite material, which reduces the overall weight of the fixing device while ensuring stable clamping and makes it easier to pick up and put down the fixing device.

[0047] Both clamping seat 3 and clamping seat 4 are provided with triangular grooves 14. The inner wall of the triangular groove 14 is made of anti-slip texture. The top edge of the triangular groove 14 is rounded to enhance the stability of clamping and facilitate the placement and removal of the mouth mirror 2. From the top view, the triangular groove 14 is triangular. The triangular groove 14 of clamping seat 3 and the triangular groove 14 of clamping seat 4 are arranged opposite to each other and abut against the outer peripheral edge of the mouth mirror 2 when clamping the mouth mirror 2.

[0048] The base 1 is fixed with a guide rail 6 for guiding the clamping direction. The guide rail 6 has an I-shaped cross-section. The clamping seats 3 and 4 slide smoothly with the guide rail 6 along the clamping direction. The I-shaped cross-section design of the guide rail 6 can effectively prevent the clamping seats 3 and 4 from shifting or falling off during the sliding process, making the operation of the entire device more stable and reliable.

[0049] The bidirectional screw 5 has a circular connecting hole 15 coaxially provided at one end facing the side plate 2 13. A circular groove is provided on the inner side of the side plate 2 13, and a cylindrical fixing pin 11 is coaxially fixed in the circular groove. The end of the bidirectional screw 5 is relatively rotatably inserted into the inner circular groove of the side plate 2 13, and the fixing pin 11 is relatively rotatably inserted into the connecting hole 15 of the bidirectional screw 5.

[0050] Working principle: The I-shaped guide rail 6 at the top center of the base 1 provides a stable sliding track for clamping seat 1 3 and clamping seat 2 4, ensuring that the two can move accurately along the rail 6.

[0051] When clamping the mouth mirror 2, the triangular grooves 14 on the top of clamping seat 1 3 and clamping seat 2 4 are used for clamping. The anti-slip texture on the inner wall of the groove 14 enhances the friction, and the rounded corners of the top edge design not only securely clamp the mouth mirror 2 but also facilitate its removal and placement. By rotating the adjustment knob 7, the bidirectional screw 5 can be rotated. Since the bidirectional screw 5 is threadedly connected to clamping seat 1 3 and clamping seat 2 4 and is restricted by the guide rail 6, the rotation of the bidirectional screw 5 will be converted into the relative approach or distance of the two clamping seats, thereby adjusting the tightness of the mouth mirror 2 clamping. The through hole in the center of side plate 1 12 provides rotational support for the bidirectional screw 5. The bidirectional screw 5 and side plate 2 13 are further guaranteed by the cooperation of the fixing pin 11 and the connecting hole 15, and the anti-slip texture on the surface of the adjustment knob 7 improves the convenience of rotation operation.

[0052] The support frame 8 at one end of the base 1 can provide additional support for the mouth mirror 2, enhancing the stability of the film application process; the universal adjustment arm 9 on the side of the clamping seat 3 can flexibly adjust the angle, and the scraper 10 at its top can eliminate air bubbles generated during the film application process as much as possible.
