Description

Technical Field

[0001] This utility model relates to the field of 3D scanner support, specifically a columnar foldable 3D scanner holder that is easy to store. Background Technology

[0002] A 3D scanner stand is a device specifically designed to support and secure a 3D scanner, ensuring stability and accuracy during the scanning process. Stands are typically made of robust materials to provide sufficient support. Their structural design allows users to flexibly adjust the height, angle, and position of the scanner to accommodate objects of different shapes and sizes. The stability of the stand helps reduce vibration and jitter, thereby improving the accuracy of the scanned data. Using a stand not only improves scanning efficiency but also reduces operator fatigue. A 3D scanner stand is an important auxiliary tool for ensuring high-quality 3D scanning results.

[0003] Chinese patent CN222559652U discloses a support device for a handheld 3D scanner, including a clamping component, a 3D scanner body, an extension rod, a telescopic rod one, a rotating base, and a tripod. The extension rod is detachable, and the telescopic rod one and telescopic rod two are telescopic and adjustable. When not in use, they can be stored away for easy carrying and assembly. The clamping component facilitates fixing and disassembling the 3D scanner. When not in use, the 3D scanner can be disassembled and packaged separately to prevent damage from bumps during movement.

[0004] During the storage process of the aforementioned patented handheld 3D scanner support device, the support rod can be rotated and stored. However, after being rotated and stored, the support rod is still exposed to the outside without any additional structure to protect it, which affects the service life of the support rod. Furthermore, when the support rod is unfolded to support the upper 3D scanner, there is no structure to limit the maximum unfolding angle of the support rod. The fixation of the unfolded support rod relies entirely on the through-hole of the positioning rod. When the 3D scanner is set up in a position where the positioning rod cannot be used, the device is difficult to use stably. Utility Model Content

[0005] The purpose of this invention is to provide a columnar, foldable, and easily stored 3D scanner holder. The collection bucket can accommodate and protect the four movable rods folded into a columnar shape. When the movable rods are fully extended and their lower ends are exposed outside the collection bucket, the pressing plate moves continuously toward the extended movable rods as the threaded rod rotates. With the rotation of the threaded rod, the movable rods can be fixed between the limiting ring and the pressing plate, limiting the extension angle of the movable rods, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a columnar, foldable, and easily stored 3D scanner holder, comprising a collection bucket, a first sliding rail inside the collection bucket, four movable rods arranged around the inside of the first sliding rail, a sliding plate inside the first sliding rail, a transmission frame at the lower end of the sliding plate, a limiting ring at the lower end of the collection bucket, a guide rod in the middle inside the first sliding rail, a connecting hole at the lower end of the guide rod, a threaded rod with threaded engagement at the lower end outside the connecting hole, and a connecting ring outside the threaded rod.

[0007] Preferably, the transmission frame is welded and fixed to the sliding plate, and the transmission frame is rotatably connected to the movable rod via a connecting shaft.

[0008] Preferably, the guide rod passes through and extends to both ends of the sliding plate, and the upper end of the guide rod is welded and fixed to the upper end of the inside of the collection bucket.

[0009] Preferably, the threaded rod is embedded inside the connecting ring and rotatably connected to the inside of the connecting ring, and four pressing plates are welded around the outside of the connecting ring.

[0010] Preferably, a limiting hole is provided at both the upper and lower ends of the first sliding rail, and a limiting piece is provided inside the limiting hole.

[0011] Preferably, the sliding piece is provided with a second sliding rail on both sides facing the limiting piece, and a connecting rod is welded to the outside of the second sliding rail facing the limiting piece.

[0012] Preferably, a spring is provided between the limiting plate and the sliding plate.

[0013] Preferably, a handle that is welded and fixed to the threaded rod is provided at the middle position of the lower end of the connecting ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. When the movable rod is folded and stored, the movable rod can rotate around the connecting shaft as the center. The four movable rods can rotate simultaneously and form a columnar structure. The four movable rods can slide longitudinally and be stored inside the first sliding rail. During the storage of the movable rod, the movable rod is restricted and protected by the collection bucket. On the other hand, when the movable rod unfolds at the lower end outside the collection bucket and supports the 3D scanner bracket at the upper end, firstly, the movable rod can rotate around the connecting shaft as the center and make the limiting ring limit the maximum angle. Secondly, the threaded rod rotates into the connecting hole and can push the pressing plate, so that the pressing plate moves towards the collection bucket and squeezes the rotated movable rod, so that the movable rod can be tightly attached between the limiting ring and the pressing plate after unfolding.

[0016] 2. When the movable rod is fixed, the spring's elasticity will actively push the limiting plate, so that after the limiting plate is embedded in the limiting hole, it can fix the sliding plate connected to the upper end of the four movable rods. When the sliding plate drives the movable rod to move smoothly along the first sliding rail, when it slides to the limiting hole, the spring's elasticity will cause the limiting plate to protrude. Actively pressing the limiting plate can make the sliding plate adjust its position as needed. The adjustment of the sliding plate is relatively convenient. Combined with the rotatable pressing plate that moves toward the collection bucket, the exposed movable rod can be fixed efficiently, and the expansion and contraction of the movable rod can be adjusted.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a columnar foldable 3D scanner holder for easy storage in this embodiment includes a collection bucket 1. A connecting frame 4 is provided at the upper end of the collection bucket 1, and the connecting frame 4 is welded and fixed to the upper end of the collection bucket 1. After the collection bucket 1 is fixed, the collection bucket 1 and the connecting frame 4 at the upper end of the collection bucket 1 can be connected to the 3D scanner to connect and support the 3D scanner.

[0026] Among them, such as Figure 3 and Figure 4 As shown, the inside of the collection bucket 1 is recessed and equipped with a first sliding rail 10. Four movable rods 2 are arranged around the inside of the first sliding rail 10. When the movable rods 2 are in use and need to support the 3D scanner at the top, the movable rods 2 can slide longitudinally and extend from the position of the first sliding rail 10. Conversely, when the movable rods 2 are stored, the movable rods 2 can slide longitudinally and be hidden inside the first sliding rail 10. The movable rods 2 can be supported by the collection bucket 1 when stored.

[0027] In addition, a sliding piece 11 is slidably provided inside the first sliding rail 10. A transmission frame 18 is provided between the lower end of the sliding piece 11 and the upper end of each of the four movable rods 2. The transmission frame 18 is welded and fixed to the sliding piece 11, and the transmission frame 18 is rotatably connected to the movable rod 2 through a connecting shaft 19. After the connection between the transmission frame 18 and the connecting shaft 19, the movable rod 2 can slide longitudinally along the first sliding rail 10 with the sliding piece 11. When the movable rod 2 needs to be unfolded, the movable rod 2 can rotate around the connecting shaft 19 as the center.

[0028] In order to limit the maximum rotation angle of the movable rod 2, a limiting ring 21 is provided around the lower end of the collection bucket 1, and the limiting ring 21 is welded and fixed to the collection bucket 1. After the movable rod 2 is rotated and unfolded, the outer wall of the movable rod 2 will come into contact with the limiting ring 21. The maximum rotation angle of the movable rod 2 can be limited by the limiting ring 21.

[0029] In order to improve the stability of the sliding plate 11 when it slides, a guide rod 9 is provided in the middle of the first sliding rail 10. The guide rod 9 passes through and extends to the upper and lower ends of the sliding plate 11. The upper end of the guide rod 9 is welded and fixed to the upper end of the collection bucket 1. When the sliding plate 11 slides, it will also be restricted by the guide rod 9 as it slides along the first sliding rail 10.

[0030] The guide rod 9 has a connecting hole 12 at its lower end and a threaded rod 20 at its lower end outside the connecting hole 12. The threaded rod 20 is threaded to the inside of the connecting hole 12. A connecting ring 7 is provided outside the threaded rod 20. The threaded rod 20 is embedded in the connecting ring 7 and rotates with the inside of the connecting ring 7. By continuously rotating the threaded rod 20 inside the connecting hole 12, the connecting ring 7 can be continuously pushed, causing the connecting ring 7 to move toward the inside of the collection bucket 1.

[0031] In addition, four pressing pieces 3 are arranged around the outside of the connecting ring 7, and the pressing pieces 3 are welded and fixed to the connecting ring 7. The four pressing pieces 3 are located between two adjacent movable rods 2. As the threaded rod 20 rotates, the pressing pieces 3 will continue to move toward the collection bucket 1 and fit against the movable rod 2, so that the two sides of the movable rod 2 are restricted and fixed in the unfolded state by the limiting ring 21 and the pressing pieces 3 respectively.

[0032] In order to fix the sliding piece 11 at different positions inside the first sliding rail 10, the upper and lower ends of both sides of the first sliding rail 10 are respectively provided with limiting holes 5, and limiting pieces 6 are provided inside the limiting holes 5. When the limiting pieces 6 protrude and are embedded inside the limiting holes 5, the sliding piece 11 and the movable rod 2 at the lower end of the sliding piece 11 can be fixed.

[0033] The sliding plate 11 has two recessed sides facing the limiting plate 6, and a connecting rod 14 is provided on the outside of the second sliding rail 13 facing the limiting plate 6. The connecting rod 14 is welded and fixed to the limiting plate 6. A spring 15 is provided between the limiting plate 6 and the sliding plate 11, and the two ends of the spring 15 are welded and fixed to the sliding plate 11 and the limiting plate 6 respectively. The elasticity of the connecting rod 14 will continuously push the limiting plate 6, so that the limiting plate 6 actively moves towards the inside of the limiting hole 5.

[0034] In addition, in order to restrict the movable connecting rod 14 and prevent it from falling off the outside of the sliding plate 11 after being pushed by the spring 15, the upper and lower ends of the second sliding rail 13 are provided with third sliding rails 17 laterally. The upper and lower ends of the connecting rod 14 are respectively provided with extension plates 16 facing the third sliding rails 17, and the extension plates 16 are welded and fixed to the outer wall of the third sliding rail 17. When the connecting rod 14 slides laterally, the extension plates 16 will slide inside the third sliding rail 17, and the third sliding rail 17 will also restrict the connecting rod 14 through the extension plates 16.

[0035] To facilitate the transmission of the threaded rod 20 and to facilitate the twisting and fixing of the extended movable rod 2, a handle 8 is provided at the middle position of the lower end of the connecting ring 7. The threaded rod 20 passes through the connecting ring 7 and is welded and fixed to the handle 8. The threaded rod 20 can be rotated through the handle 8.

[0036] Working principle: When using the device and supported by the movable rod 2, press the limiting plate 6, causing the limiting plate 6 to slide into the collection bucket 1 and move to the outside of the limiting hole 5. Slide the sliding plate 11 longitudinally, and the sliding plate 11 drives the movable rod 2 to extend from the lower end of the collection bucket 1. After the sliding plate 11 has completely slid to the lower end of the first sliding rail 10, the limiting plates 6 on both sides of the sliding plate 11 will be pushed by the spring 15 and re-enter the corresponding limiting hole 5. After extending, the movable rod 2 rotates outside the transmission frame 18 with the connecting shaft 19 as the center. The movable rod 2 is rotated and unfolded. The threaded rod 20 is rotated and embedded in the connecting hole 12. With the threaded engagement between the threaded rod 20 and the connecting hole 12, after the threaded rod 20 continues to rotate, the threaded rod 20 will drive the pressing plate 3 to move towards the collection bucket 1 through the connecting ring 7. With the pressing plate 3 pressing, the movable rod 2 is pressed tightly against the limiting ring 21.
