Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental radiography, specifically to an adjustable dental radiography support. Background Technology
[0002] A dental X-ray is an X-ray film of teeth, also known as an intraoral standard film. A single dental X-ray can show 3-4 teeth, which appear as white radiopaque images on the film.
[0003] The use of dental CCD imaging plates is very common in the process of taking dental X-rays. The simplest method is to insert the plate directly behind the teeth in the mouth to form an image.
[0004] However, existing imaging boards are often only compatible with one type of CCD, resulting in a limited range of applications. In addition, existing imaging boards are fixed by a hand-held handle, which can easily loosen during shooting and cause positional changes, thus affecting the shooting of dental X-rays. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable dental radiography support.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] An adjustable dental radiography bracket includes a connecting plate with symmetrically arranged limit plates on both sides. Each limit plate has a sliding groove on both sides and a downward-facing toothed groove above the sliding groove. A movable plate is slidably disposed within the sliding groove on the limit plate, forming a clamping slot for a CCD between the limit plate and the movable plate. A toothed plate is disposed on the movable plate, and a pressing plate is hinged to it. Normally, the pressing plate is tilted, with one end abutting the top surface of the limit plate. The toothed plate is inserted into the toothed groove. When the pressing plate is pressed to a horizontal position, the shortest distance between the pressing plate and the limit plate increases, and the toothed plate disengages from the toothed groove, allowing the movable plate to slide within the sliding groove.
[0008] Preferably, under normal conditions, the tilt angle of the pressing plate is no greater than 30°.
[0009] Preferably, the movable plate is located between the limiting plates on both sides of the connecting plate.
[0010] Preferably, the connecting plate has a fixing plate with a groove in the middle, which is symmetrically arranged on both sides.
[0011] Preferably, the wall thickness of the fixing plate is no more than 1 cm.
[0012] Preferably, the fixing plate is located on one side of the limiting plate, and the fixing plate is correspondingly disposed between the limiting plate and the moving plate.
[0013] Preferably, the connecting plate, fixing plate, limiting plate, moving plate, pressing plate, and toothed plate are all made of medical-grade plastic.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model moves the pressing plate from an inclined state to a horizontal state by pressing it, increasing the shortest distance between the pressing plate and the limiting plate, thereby causing the toothed plate to disengage from the toothed groove and enabling the moving plate to slide in the groove. This changes the distance between the moving plate and the limiting plate, so that the slot between the moving plate and the limiting plate can be used for CCDs of different sizes, thus increasing the applicability.
[0016] 2. When using this utility model, the patient bites the platform formed between the side of the fixing plate and the groove with their teeth to achieve fixation. Compared with the traditional fixation method by holding the handle, it is more stable and less prone to movement, while also avoiding radiation to the hand. Attached Figure Description

It should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] like Figure 1As shown, an adjustable dental radiography support according to this utility model includes a connecting plate 1. A fixing plate 2 and a limiting plate 3 are symmetrically arranged on both sides of the connecting plate 1. The symmetrical structure allows one end to shoot to the upper left and lower right, and the other end to shoot to the lower left and upper right, thereby enabling comprehensive shooting.
[0025] like Figure 1 As shown, the limiting plate 3 is an L-shaped plate. Slide grooves are provided on both sides of the horizontal portion of the limiting plate 3. Toothed grooves 7 are provided on both sides of the limiting plate 3, located above and facing downwards from the slide grooves. A vertically positioned movable plate 4 is slidably mounted within the slide grooves. A groove is formed between the vertical portion of the limiting plate 3 and the movable plate 4. Figure 2 As shown, a toothed plate 6 is provided on the movable plate 4, and an inclined pressing plate 5 is also hinged to the movable plate 4. Under normal conditions, the pressing plate 5 is in an inclined state, with one end of the pressing plate 5 abutting against the top surface of the limiting plate 3, and the toothed plate 6 inserted into the toothed groove 7. At this time, the movable plate 4 cannot move. When the pressing plate 5 is pressed to make it horizontal, the shortest distance between the pressing plate 5 and the limiting plate 3 increases by the height of the toothed plate 6. The toothed plate 6 disengages from the toothed groove 7, allowing the movable plate 4 to slide in the groove, thereby changing the distance between the movable plate 4 and the limiting plate 3. This allows the slot between the movable plate 4 and the limiting plate 3 to clamp CCDs of different sizes, increasing the applicability.
[0026] like Figure 2 As shown, under normal conditions, the tilt angle of the pressing plate 5 is set to 15°. The appropriate angle ensures that the height change of the pressing plate 5 is not too large when it moves from the tilted state to the horizontal state, so that the overall device is not too thick, which indirectly ensures that the shooting work can be carried out stably. The moving plate 4 is located between the limiting plates 3 on both sides of the connecting plate 1, ensuring the stability of the vertical part of the limiting plates 3 on both sides, and ensuring that the limiting plate 3 is the end, rather than the sliding moving plate 4, so as to ensure that the clamped CCD can carry out comprehensive shooting work to the maximum extent.
[0027] like Figure 3 As shown, a groove is provided in the middle of the fixing plate 2. The wall thickness of the fixing plate 2 is set to 0.2cm. When in use, the patient bites the fixing plate 2 with his teeth to fix the plate by the platform formed between the side of the fixing plate and the groove. Compared with the traditional fixing method by holding the handle, it is more stable and less prone to movement, and also avoids radiation to the hand. The fixing plate 2 is located on one side of the limiting plate 3, and the fixing plate 2 is correspondingly set between the limiting plate 3 and the moving plate 4 to ensure that the distance between the fixing plate 2 and the CCD is not too large, thereby avoiding the problem that the fixing plate 2 cannot be bitten by the patient due to the large distance.
[0028] The length of the connecting plate 1 is set to 8cm, the height of the limiting plate 3 is set to 3cm, and the sum of the widths of the limiting plate 3 and the fixing plate 2 is set to 2cm. The appropriate size ensures that the device can perform stable shooting operations. The connecting plate 1, fixing plate 2, limiting plate 3, moving plate 4, pressing plate 5, and toothed plate 6 are all made of medical-grade plastic material to ensure hygiene and safety.
[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
