Description

Technical Field

[0001] This utility model relates to the field of dental digital impression instrument technology, and in particular to a calibration device for dental digital impression instruments. Background Technology

[0002] A digital impression instrument is a device used to acquire digital information about the oral cavity structure, typically used in dental diagnosis, treatment planning, and the fabrication of dental prostheses. This device generates a high-precision digital 3D model by scanning the internal structure of the patient's mouth, providing doctors with detailed oral information. A calibration device for the digital impression instrument is used to calibrate it, ensuring scanning accuracy and precision. Existing calibration devices often have their working ends exposed after use, lacking protection and susceptible to damage from impacts. Furthermore, dust and debris can easily enter the working end, causing image obstruction and other malfunctions during use. Therefore, we have introduced a calibration device for digital impression instruments. Utility Model Content

[0003] The main objective of this invention is to provide a calibration device for a digital dental impression instrument, which can effectively solve the problems in the background art.

[0006] Preferably, the protective device includes a first housing, and a second housing is fixedly connected to the right end of the first housing. The second housing and the first housing are an integral structure. The height of the first housing is less than the height of the second housing. The second housing has a slot inside and the width of the second housing is the same as the width of the first housing.

[0007] Preferably, two metal blocks are fixedly connected to the lower left side of the first housing, a rotating rod is fixedly connected to the lower left side of the first housing, and connectors are movably connected to the front and rear of the outer surface of the rotating rod. The right ends of the two connectors are arc-shaped, the lower left ends of the two connectors are arc-shaped, a protective plate is fixedly connected to the upper left side of the two connectors, and a magnetic block is fixedly connected to the lower end of each of the two connectors.

[0008] Preferably, the positions of the two No. 1 magnetic blocks correspond to the positions of the two No. 1 metal blocks, respectively.

[0009] Preferably, a second magnetic block is fixedly connected to both the front left end and the rear left end of the first housing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A calibration device for a digital impression instrument for oral cavity includes a calibration device body 1, a working end 2 is provided at the left end of the calibration device body 1, a wire harness 4 is installed and connected at the right end of the calibration device body 1, and a protective device 3 is movably connected to the outer surface of the calibration device body 1.

[0024] In this embodiment, the protective device 3 includes a first housing 31, with a second housing 33 fixedly connected to the right end of the first housing 31. The second housing 33 and the first housing 31 are an integral structure. The height of the first housing 31 is less than the height of the second housing 33. The second housing 33 has a slot 32 inside, and its width is the same as that of the first housing 31. Two first metal blocks 311 are fixedly connected to the lower left part of the first housing 31. A rotating rod 314 is fixedly connected to the lower left part of the first housing 31. Connecting pieces 313 are movably connected to both the front and rear parts of the outer surface of the rotating rod 314. The right ends of both connecting pieces 313 are arc-shaped, and the lower left parts of both connecting pieces 313 are arc-shaped. The structure consists of two connectors 313, with a protective plate 312 fixedly connected to the upper left side of each connector 313. A first magnetic block 315 is fixedly connected to the lower end of each connector 313. The positions of the two first magnetic blocks 315 correspond to the positions of the two first metal blocks 311. A second magnetic block 316 is fixedly connected to the front left end and the rear left end of the first housing 31. A second metal block 317 is fixedly connected to the front right end and the rear right end of the protective plate 312. The positions of the two second metal blocks 317 correspond to the positions of the two second magnetic blocks 316. Both the first housing 31 and the second housing 33 are inserted into the calibration device body 1, and the slot 32 is adapted to the shape of the calibration device body 1.

[0025] With the above scheme: the first housing 31 is pulled smoothly to the right, the angle of the protective plate 312 is adjusted, and the first magnetic block 315 at the bottom of the protective plate 312 will automatically be magnetically attracted to the first metal block 311 at the bottom of the first housing 31, so that the working end 2 is fully exposed and can be used. Conversely, the working end 2 is covered to prevent foreign objects from entering the working end 2.

[0026] It should be noted that this utility model describes a calibration device for a digital dental impression instrument. When the calibration device is needed, the user simply pulls the first housing 31 smoothly to the right. The protective plate 312 installed on the left end of the first housing 31 is gently pushed open by the working end 2 on the left end of the calibration device body 1. The angle of the protective plate 312 is adjusted without causing any damage to the working end 2. After the angle adjustment is completed, the first magnetic block 315 at the bottom of the protective plate 312 will automatically and tightly magnetically attract the first metal block 311 at the bottom of the first housing 31, preventing it from closing accidentally. This also ensures that the working end 2 is fully exposed without any obstruction, thus facilitating accurate calibration work for the user. The complete exposure of the working end 2 makes the calibration process more intuitive and efficient, improving work efficiency. After use, the user simply reverses the operation and moves the first housing 31 to the left. At this time, the protective plate 312 can be gently moved back to its original position. During this process, the second metal block 317 on the protective plate 312 will be precisely aligned and magnetically connected with the second magnetic block 316 on the left end of the first housing 31, ensuring that the protective plate 312 is tightly attached to the first housing 31, effectively enclosing the working end 2, avoiding potential damage to the working end 2 from dust, debris or accidental contact, and ensuring the long service life and accuracy of the calibration device.
