Description

Technical Field

[0001] The utility model relates to the field of 3D scanners, in particular to a 3D scanner rapid assembly structure. Background Art

[0002] 3D scanners include two usages: handheld and fixed, which are used in different scanning scenarios. Due to the high cost of scanners, it is difficult to equip both handheld 3D scanners and fixed 3D scanners in general production processes. Therefore, in order to control costs and have two usages, a quick-change mechanism is needed. There is currently a quick-change mechanism for 3D scanners, which opens a slot on the housing of the 3D scanner, installs an insert plate on the handle or fixing bracket to be installed, and directly inserts the insert plate into the slot horizontally to achieve rapid disassembly and assembly of the scanner. However, this assembly structure can only play a good fixing role in the Z axis, that is, in the vertical direction. In the horizontal direction, there is still a hidden danger that the 3D scanner will slide along the slot direction. Therefore, an additional fixing structure is required, such as using bolts to tighten the insert plate to the 3D scanner, etc. Therefore, during assembly, in addition to inserting the insert plate into the slot, multiple bolts need to be tightened, which greatly affects the assembly speed. Utility Model Content

[0003] The purpose of this application is to provide a 3D scanner rapid assembly structure, aiming to solve the problems existing in the prior art.

[0004] The present invention provides a quick assembly structure for a 3D scanner, comprising a slot on the 3D scanner and an insert plate that can be inserted into the slot, wherein one end of the insert plate is free and the other end is fixedly connected to a quick-change base; a liftable stop post is provided inside the quick-change base, and limiting holes are provided on the quick-change base and the insert plate corresponding to the stop post, and a limiting hole is provided in the slot corresponding to the stop post; the stop post rises along the limiting hole, passes through the insert plate, and stays in the slot;

[0005] An annular knob is rotatably provided inside the quick-change base, and a driving wheel is meshed with teeth on the inner side of the knob.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1 and Figure 2The figure shows a quick assembly structure for a 3D scanner, comprising a slot 3 on a 3D scanner 1 and an insert plate 4 that can be inserted into the slot 3. One end of the insert plate 4 is free and the other end is fixedly connected to the quick-change base 2. The 3D scanner 1 and the quick-change base 2 are installed together by inserting the insert plate 4 into the slot 3.

[0020] The 3D scanner 1 is secured to the quick-change base 2 not only by the insert plate 4 but also by a retractable stopper 5 located within the quick-change base 2. Limiting holes 6 are provided on both the quick-change base 2 and the insert plate 4, corresponding to the stopper 5. A corresponding limiting hole 6 is also provided within the slot 3. A gap exists between the insert plate 4 and the slot 3 to facilitate its movement. The stopper 5 ascends along the limiter hole 6, passes through the insert plate 4, and rests in the slot 3. The insert plate 4 and slot 3 secure the 3D scanner 1 in the Z axis, while the stopper 5 secures the 3D scanner 1 to the quick-change base 2 in the X and Y axes, thereby ensuring a more stable connection between the 3D scanner 1 and the quick-change base 2.

[0021] like Figure 3 and Figure 4 As shown, a ring-shaped knob 7 is rotatably mounted within the quick-change base 2. A drive wheel 8 is meshed with teeth on its inner side. The rotating shaft of the drive wheel 8 is mounted on the quick-change base 2, preventing the drive wheel 8 from moving and only being driven by the knob 7. An inner sleeve 9 is fixedly connected to the drive wheel 8, and a Z-shaped retaining groove 10 is defined on its circumference. The lower end of the retaining post 5 is fixedly connected to a lifting seat 11, and a pin 12 is fixedly attached to its circumference. Both the retaining post 5 and the lifting seat 11 are located within the inner sleeve 9, with clearance between them and the inner sleeve 9, allowing them to move up and down within the inner sleeve 9. The pin 12 extends from the retaining groove 10, limiting its position during the lifting process.

[0022] An outer sleeve 13 is provided at intervals on the outside of the inner sleeve 9 . The outer sleeve 13 is fixed relatively to the quick-change base 2 . A spirally extending slide groove 14 is provided on the inner circumference of the outer sleeve 13 . The pin shaft 12 is slidably provided in the slide groove 14 .

[0023] The lifting mechanism works as follows: When the drive wheel 8 rotates, it drives the inner sleeve 9, causing it to rotate within the outer sleeve 13. This, in turn, drives the pin 12, the lift base 11, and the stop post 5 together through the stop slot 10. Because the pin 12 is also restrained by the slide slot 14, the rotating lift base 11 ascends or descends along the spiral slide slot 14, allowing the lift base 11 and the stop post 5 to ascend or descend. When ascending or descending to the horizontal portion of the stop slot 10, the stop slot 10 limits the pin 12, fixing the height of the pin 12 and lift base 11, thereby maintaining the height of the stop post 5.

[0024] A window 15 is provided on the side of the quick-change base 2 corresponding to the knob 7, and a portion of the knob 7 is exposed from the window 15. Figure 2 As shown, the outer peripheral surface of the knob 7 is provided with anti-slip ridges, and the knob 7 can be manually turned to rotate the knob 7.

[0025] The knob 7 is engaged with a plurality of driving wheels 8 . In this embodiment, six driving wheels are used as an example. Each driving wheel 8 corresponds to a blocking column 5 and there are also six corresponding limiting holes 6 . The six blocking columns 5 and limiting holes 6 are distributed in a hexagonal shape.

[0026] One end of the quick-change base 2 is fixedly connected to a vertical baffle 16 , and the plug plate 4 is fixedly connected to the baffle 16 ; the height of the baffle 16 is higher than the height of the plug plate 4 , and the baffle 16 serves as a shielding and abutting portion of the 3D scanner 1 .

[0027] In this embodiment, a sub-base 17 is mounted on the bottom of the 3D scanner 1. The slot 3 is located on the sub-base 17. A stopper hole 6 is formed on the sub-base 17 below the slot 3 to accommodate the passage of the stopper 5. During use, the quick-change base 2 is mounted on the handle or fixed base. This allows the 3D scanner 1 to be quickly assembled on the handle or fixed base for handheld or fixed scanning.

[0028] During assembly, first insert the insert plate 4 into the corresponding slot 3 to initially secure the 3D scanner 1 to the quick-change base 2. Then, turn the side knob 7, rotating the knob 7 to drive the internal drive wheel 8, causing the stopper 5 to rise until it passes through the auxiliary seat 17 and the insert plate 4. When the stopper 5 reaches its highest point, it is restrained by the horizontal portion of the limit slot 10. Even if it is affected by the weight of the 3D scanner 1, the stopper 5 will not fall, thus achieving the final fixation of the 3D scanner 1 to the quick-change base 2. For removal or replacement, turn the knob 7 in the opposite direction to lower the stopper 5 to its lowest point, and then move the 3D scanner 1 laterally off the insert plate 4.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
