Description

Technical Field

[0001] This utility model relates to the field of support devices, and in particular to a stable support for an external oral cavity 3D scanning measurement instrument. Background Technology

[0002] External 3D scanning and measurement instruments are important digital diagnostic and treatment devices in the field of oral medicine. They can acquire three-dimensional morphological data of a patient's face, teeth, and jawbone through non-contact scanning, providing accurate digital models for orthodontic treatment, implant restoration, and maxillofacial surgery planning. This device requires extremely high stability of the support structure; even slight shaking or displacement can lead to data distortion and affect the accuracy of subsequent treatment plans.

[0003] Currently, most dental scanning equipment stands on the market adopt a traditional triangular support structure, with the legs typically connected to the stand body via fixed hinges or a telescopic structure. However, this type of stand has significant drawbacks in practical use: when the stand is open, the fulcrum of the legs (i.e., the contact point between the legs and the ground) is often designed at a fixed angle, making it difficult to adapt to uneven ground environments. For example, in clinical settings, the floor may have tile grout lines, uneven carpet pile thickness, etc., and the fixed fulcrum is prone to tilting due to uneven force. In addition, when medical staff or patients accidentally bump into the stand, the fixed fulcrum cannot adaptively adjust to offset the impact force, causing the entire stand to shake or even tip over, seriously affecting scanning accuracy and equipment safety.

[0004] Therefore, a stable support for an external oral cavity 3D scanning measurement instrument is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a solution to address the issue that the fulcrum of existing supports cannot adapt to uneven surfaces and is unstable upon collision.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stabilizing bracket for an external oral 3D scanning and measuring instrument includes a bracket body for connecting to a scanner. The bracket body has at least three support legs connected to its bottom. Each support leg has a stabilizing rod connected to its bottom through a movable groove. The stabilizing rod is omnidirectionally rotatable relative to the movable groove. The bottom end of the stabilizing rod is provided with a rod bottom for contacting a support surface.

[0008] Preferably, a threaded rod is provided in the movable groove, and one end of the stabilizing support rod is threadedly connected to the threaded rod through a connecting sleeve. The bottom of the support rod is coplanar with the support plate at the bottom of the support leg or forms a support surface.

[0009] Preferably, the movable groove has mounting holes at both ends that extend across the outer wall of the support leg, and the threaded rod can rotatably pass through the mounting holes.

[0010] Preferably, the bottom of the support rod is spherical, and an anti-slip sleeve is embedded in the middle of the outer periphery of the support rod bottom.

[0011] Preferably, the surface of the anti-slip sleeve is uniformly provided with a number of protrusions.

[0012] Preferably, the anti-slip sleeve and the raised dots are integrally molded from rubber material, and the raised dots are distributed radially.

[0013] Preferably, a hand-held hole is provided in the middle of the bottom of the support rod.

[0014] Preferably, one end of the threaded rod is connected to a rotating handle, and the other end is locked to the outer wall of the support leg by a locking nut.

[0015] Preferably, the rotating handle has an inner washer facing the inner end face of the support leg, and the inner washer is in contact with the outer wall of the support leg.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The stable support of the oral external 3D scanning and measuring instrument provided in this application is connected to a rotatable stable support rod through a movable slot, so that the fulcrum can dynamically adjust the angle according to the ground conditions and impact force to achieve adaptive stability. This effectively solves the problems of tilting and easy shaking and tipping of traditional supports due to uneven ground and uneven force, and ensures scanning accuracy and equipment safety.

[0018] The bottom of the support rod is fitted with a rubber anti-slip sleeve with radial protrusions, which greatly increases the friction with the support surface and can maintain stability on soft or uneven surfaces such as carpets; the rotating handle is equipped with anti-slip texture and inner washer, which makes it easy to tighten and avoids wear; the hand-held hole at the bottom of the support rod makes it easy to manually rotate and adjust the angle, and with the threaded fine adjustment, it can improve the convenience of use.

Example

[0030] Please see Figure 1-5A stabilizing bracket for an external oral 3D scanning measurement instrument includes a bracket body 1 for connecting to a scanner. The bracket body 1 has at least three support legs 2 connected to its bottom. Each support leg 2 has a stabilizing rod 5 connected to its bottom through a movable groove 3. The stabilizing rod 5 is omnidirectionally rotatable relative to the movable groove 3. The bottom end of the stabilizing rod 5 is provided with a rod bottom 52 for contacting the support surface.

[0031] The stable support of the external oral cavity 3D scanning measurement instrument of this application is mainly composed of the support body 1, support leg 2, movable groove 3, stable support rod 5 and support rod base 52, etc. The following is a detailed description of the structure and working principle.

[0032] like Figure 1 As shown, the top of the support body 1 is used to connect to the scanner, and the bottom of the body is connected to at least three support legs 2. In this embodiment, the three support legs 2 are preferably arranged in a triangular pattern to form a stable support structure. Each support leg 2 has a movable groove 3 at its bottom, which extends laterally along the support leg 2 and penetrates to the outer walls of both sides of the support leg 2.

[0033] A threaded rod 4 is installed inside the movable groove 3. Both ends of the threaded rod 4 pass through mounting holes 31 opened horizontally on the outer wall of the support leg 2 at both ends of the movable groove 3, allowing the threaded rod 4 to rotate freely within the mounting holes 31. One end of the threaded rod 4 is connected to a rotating handle 41. The surface of the rotating handle 41 is provided with anti-slip texture for easy operation. A rubber inner washer 411 is provided on the inner end face of the rotating handle facing the support leg 2. When the rotating handle 41 is tightened, the inner washer 411 is in close contact with the outer wall of the support leg 2, increasing friction and preventing wear. The other end of the threaded rod 4 is locked to the outer wall of the support leg 2 by a locking nut 42 to ensure that the threaded rod 4 is installed securely.

[0034] Each movable slot 3 is connected to a stabilizing support rod 5 via a threaded rod 4. One end of the stabilizing support rod 5 is equipped with a connecting sleeve 51, the inner wall of which has an internal thread matching the threaded rod 4, thus forming a threaded connection. The stabilizing support rod 5 can rotate omnidirectionally around the threaded rod 4 to adapt to different ground angles. The bottom end of the stabilizing support rod 5 has a support rod base 52, which is spherical in design. A rubber anti-slip sleeve 6 is embedded in the center of its outer circumference. The surface of the anti-slip sleeve 6 is evenly distributed with radially distributed protrusions 61 to increase friction with the supporting surface. A hand-held hole 521 is provided in the center of the support rod base 52 for easy manual rotation of the stabilizing support rod 5.

[0035] The bottom of the support leg 2 is provided with a support plate 21. The bottom of the support rod 52 can be adjusted to be coplanar with the support plate 21 by rotating the stabilizing support rod 5, or adjusted to form an independent support surface at a certain angle with the support plate 21 according to the unevenness of the support surface, so as to achieve self-adaptive support.

[0036] Working principle

[0037] Installation and initial adjustment: The threaded rod 4 is passed through the mounting hole 31 by rotating the handle 41, positioning it within the movable groove 3. The threaded rod 4 is then locked to the outer wall of the support leg 2 using the locking nut 42. At this point, the stabilizing rod 5 is threadedly connected to the threaded rod 4 via the connecting sleeve 51, allowing it to rotate omnidirectionally around the threaded rod 4. The user can rotate the stabilizing rod 5 through the hand-held hole 521 to adjust the angle of the rod base 52, making it coplanar with the support plate 21 at the bottom of the support leg 2 or forming an independent support surface to adapt to different support environments.

[0038] The adaptive stabilization adjustment allows the support rod 5 to rotate omnidirectionally to accommodate uneven surfaces, such as tile seams or uneven carpet pile thickness. This ensures the rod base 52 fits snugly against the support surface. The spherical design of the rod base 52 allows for flexible angle adjustment in multiple directions, ensuring stable contact between the fulcrum of each support leg 2 and the ground, preventing tilting due to uneven force. Simultaneously, the anti-slip sleeve 6 and protrusions 61 increase friction between the fulcrum and the support surface, further enhancing stability.

[0039] Impact Force Mitigation: When the support structure is subjected to an accidental impact, the spherical base 52 of the support rod can disperse the impact force, and the stabilizing support rod 5 can rotate briefly in the direction of the impact force, thus mitigating part of the impact force and reducing the overall swaying of the support structure. At the same time, the threaded connection between the threaded rod 4 and the connecting sleeve 51 provides a certain amount of damping, allowing the stabilizing support rod 5 to maintain its position after the angle is adjusted, preventing the support structure from tipping over.

[0040] Once the stabilizing support rod 5 is adjusted to the appropriate angle, its connecting sleeve 51 and the threaded rod 4 are locked in place by a self-locking mechanism, ensuring that it does not shift due to vibration during scanning. For disassembly, first loosen the locking nut 42, then rotate the rotating handle 41 to allow the threaded rod 4 to rotate out of the unthreaded mounting hole 31. Simultaneously, manually rotate the stabilizing support rod 5 so that its connecting sleeve 51 unscrews along the threads of the threaded rod 4, thus separating the stabilizing support rod 5 for easy maintenance and transport. This design achieves angle locking through a self-locking threaded connection and facilitates convenient disassembly through the rotation of the threaded rod 4 combined with the screwing and unscrewing of the support rod. The structure is compact and the operation is highly efficient.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
