Description

Technical Field

[0001] This invention relates to the field of 3D scanner adjustment technology, and more specifically to a 3D scanner that is easy to adjust. Background Technology

[0002] A 3D scanner is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often used for 3D reconstruction calculations to create digital models of actual objects in the virtual world. 3D scanners are classified into two types: contact and non-contact. The latter can be further divided into active scanning and passive scanning. Non-contact active scanning involves projecting additional energy onto the object and calculating 3D spatial information through the reflection of the energy.

[0003] When using non-contact active scanning, the scanner often needs to be adjusted. However, existing scanners are adjusted by simply tightening or loosening bolts. Therefore, adjusting the scanning height or scanning angle of a 3D scanner will affect the scanning angle or scanning height. Or, when adjusting the scanning angle and scanning height at the same time, not only is over-adjustment and under-adjustment easy to occur, but the scanner also needs to be adjusted multiple times to achieve the required angle and height, resulting in wasted time and reduced work efficiency. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an easily adjustable 3D scanner, which can effectively solve the problem that the scanner in the existing technology is prone to over-adjustment and under-adjustment during the adjustment process, resulting in wasted time and reduced work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides an easily adjustable 3D scanner, including a scanner body and a support shaft fixedly mounted on its lower surface, and further including: a first collar sleeved on the outer surface of the support shaft, the inner wall of the first collar having an installation groove, the installation groove being connected to a vertical groove through a circular hole, and a second collar being rotatably connected to the lower end of the first collar.

[0007] It also includes a positioning mechanism for fixing the support shaft. The positioning mechanism includes a positioning rod located inside the mounting groove and an adjusting block that can move up and down to adjust the angle of the scanner body. The left end of the positioning rod is rotatably connected to a round rod, and a handle is fixedly installed on the left end of the round rod. An arc plate is fixedly installed on the surface of the round rod, and a strip magnetic block is fixedly installed on the outer arc surface of the arc plate. A limit rod is fixedly installed on the upper end of the adjusting block, and a magnetic ring is embedded in the upper end of the limit rod.

[0008] Furthermore, the surface of the support shaft is provided with a strip-shaped notch, and the inner wall of the strip-shaped notch is provided with multiple sets of fixing holes at equal intervals.

[0009] Furthermore, the upper end of the second ring is provided with multiple sets of adjustment holes at equal intervals, and the planar structure of the adjustment holes is a trapezoidal structure.

[0010] Furthermore, the positioning rod is elastically connected to the inner wall of the mounting groove via a connecting spring, and the connecting spring is sleeved on the outside of the round rod. The right end of the positioning rod is engaged with the fixing hole.

[0011] Furthermore, the adjusting block is located inside the vertical groove, and the adjusting block is elastically connected to the inside of the vertical groove through a return spring. The lower end of the adjusting block is adapted to the shape of the adjusting hole.

[0012] Furthermore, the upper end of the limiting rod is located inside the circular hole, and the limiting rod slides in contact with the inner wall of the circular hole.

[0013] Furthermore, the bar magnet is located directly above the circular hole, and the opposing surfaces of the bar magnet and the magnetic ring are magnetically repelled.

[0014] Furthermore, it also includes an auxiliary component for controlling the movement of the round rod. The auxiliary component includes a limiting ring fixedly installed on the surface of the first ring. The surface of the limiting ring is provided with a U-shaped groove. The inner wall of the groove is symmetrically provided with two sets of positioning holes, one of which is fitted with an elastic telescopic rod.

[0015] Furthermore, the limiting ring is sleeved on the outside of the round rod and located inside the handle, and the elastic telescopic rod is fixedly installed on the inner wall of the handle.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0017] This invention, through its positioning mechanism and auxiliary components, allows for adjustments to the scanner body. By rotating the adjustment handle, the round rod rotates the arc-shaped plate, causing the strip magnetic block to deviate from the magnetic ring, enabling the adjustment block to move vertically and thus adjusting the scanner body's angle. Alternatively, pulling the handle moves the round rod laterally, causing the positioning rod to separate from the fixing hole. As the positioning rod separates, the strip magnetic block moves synchronously with the round rod and continuously repels the magnetic ring, unlocking the fixed support shaft and allowing height adjustment of the scanner body. Furthermore, pulling the handle directly shifts the strip magnetic block below the arc-shaped block relative to the magnetic ring, unlocking the support shaft and adjustment block, enabling simultaneous adjustment of the scanner body's height and angle, saving time and increasing work efficiency.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example: An easily adjustable 3D scanner, such as Figures 1-8 As shown, the device includes a scanner body 1 and a support shaft 2 fixedly mounted on its lower surface for adjusting the height and scanning angle of the scanner body 1. The surface of the support shaft 2 has a strip-shaped notch 201, which serves as a guide and limiter. The inner wall of the strip-shaped notch 201 has multiple sets of fixing holes 202 at equal intervals, which can cooperate with other components to fix the support shaft 2.

[0031] It also includes a first ring 3 sleeved on the outer surface of the support shaft 2. By setting the first ring 3, the support shaft 2 can be fixed and limited, so as to facilitate the lifting and lowering of the support shaft 2. The inner wall of the first ring 3 has a mounting groove 301 for mounting components. The mounting groove 301 is connected to a vertical groove 302 through a round hole. By setting the vertical groove 302, it can play a guiding and limiting role. The lower end of the first ring 3 is rotatably connected to a second ring 4. By setting the second ring 4 rotatably connected to the first ring 3, it can cooperate with the first ring 3 to allow the scanner body 1 to rotate and adjust the angle. The upper end of the second ring 4 has multiple sets of adjustment holes 401 equidistantly set. The planar structure of the adjustment holes 401 is a trapezoidal structure. By setting the adjustment holes 401, the adjustment angle of the scanner body 1 can be fixed. That is, the included angle of every two sets of adjustment holes 401 is the same. It is worth noting that the number of adjustment holes 401 can be set as needed and is not limited to the number shown in the attached figure.

[0032] Combined with appendix Figure 1 -Appendix Figure 8It also includes a positioning mechanism 5 for fixing the support shaft 2, which ensures that the scanner body 1 is in a stable state after adjustment, thus ensuring the accuracy of the scanning results. The positioning mechanism 5 includes a positioning rod 501 and an adjusting block 506 located inside the mounting groove 301. By setting the positioning rod 501 and the adjusting block 506, the scanning height and scanning angle of the scanner body 1 can be controlled respectively. A round rod 502 is rotatably connected to the left end of the positioning rod 501. By setting the round rod 502, it can serve as a connection. A handle 5021 is fixedly installed on the left end of the round rod 502. By setting the handle 5021, the round rod 502 can be rotated synchronously by changing the position of the handle 5021.

[0033] The positioning rod 501 is elastically connected to the inner wall of the mounting groove 301 via a connecting spring 503, and the connecting spring 503 is sleeved on the outside of the round rod 502. By setting the connecting spring 503, a reaction force can be generated when it is compressed and deformed, which will drive the positioning rod 501 to return to its original position. The right end of the positioning rod 501 is engaged with the fixing hole 202. By engaging the positioning rod 501 with the fixing hole 202, the support shaft 2 can be fixed.

[0034] An arc-shaped plate 504 is fixedly mounted on the surface of the round rod 502, and a strip magnetic block 505 is fixedly mounted on the outer arc surface of the arc plate 504. By setting the arc plate 504 and the strip magnetic block 505, the rod can move synchronously with the round rod 502 to achieve the purpose of changing position. It is worth noting that in the initial state, the left part of the strip magnetic block 505 is located directly above the round hole. The adjusting block 506 is located inside the vertical groove 302, and the adjusting block 506 is elastically connected to the inside of the vertical groove 302 through a return spring. The return spring can be referred to the attached diagram. Figure 5 The adjustment block 506 can be restored to its original shape by the reaction force generated when it deforms. The lower end of the adjustment block 506 is adapted to the shape of the adjustment hole 401. By setting the adjustment block 506, it can cooperate with the adjustment hole 401 to realize the angle adjustment of the scanner body 1, ensuring that the angle is the same every time. It is worth noting that when the scanner body 1 is adjusted, the lower end of the adjustment block 506 will be squeezed against the adjustment hole 401, which will cause the adjustment block 506 to move upward and compress the reset spring. When the lower end of the adjustment block 506 moves from one set of adjustment holes 401 to the inside of another set of adjustment holes 401, a "click" sound will be made to remind the operator that the angle adjustment is complete.

[0035] The upper end of the adjusting block 506 is fixedly equipped with a limiting rod 507. The upper end of the limiting rod 507 is located inside the circular hole, and the limiting rod 507 slides with the inner wall of the circular hole. By setting the limiting rod 507, the adjusting block 506 can be limited, ensuring the movement trajectory of the adjusting block 506. A magnetic ring 508 is embedded in the upper end of the limiting rod 507. A bar magnetic block 505 is located directly above the circular hole, and the opposing surfaces of the bar magnetic block 505 and the magnetic ring 508 repel each other magnetically. By setting the magnetic ring 508, it can cooperate with the bar magnetic block 505 to fix the adjusting block 506.

[0036] Combined with appendix Figure 1 -Appendix Figure 8 It also includes an auxiliary component 6 for controlling the movement of the round rod 502, so as to realize the raising and lowering of the scanning height of the scanner body 1 and the adjustment of the scanning angle; the auxiliary component 6 includes a limiting ring 601 fixedly installed on the surface of the first ring 3. The limiting ring 601 is sleeved on the outside of the round rod 502 and is located inside the handle 5021. By setting the limiting ring 601, the handle 5021 can be limited, ensuring that the handle 5021 can continuously cooperate with the limiting ring 601.

[0037] The limiting ring 601 has a U-shaped groove 602 on its surface, which serves to guide and limit movement. The inner wall of the groove 602 has two sets of positioning holes 603 symmetrically arranged. One set of positioning holes 603 has an elastic telescopic rod 604 engaged inside it. The elastic telescopic rod 604 is fixedly installed on the inner wall of the handle 5021. By setting the positioning holes 603 and the elastic telescopic rod 604, the handle 5021 can be limited, ensuring that the handle 5021 can only slide inside the groove 602.

[0038] Specifically, when only height adjustment is needed during the use of the scanner body 1, simply pull the handle 5021 outward, causing the handle 5021 to drive the elastic telescopic rod 604 to slide on one side of the slide groove 602, and through the round rod 502 fixedly connected to it, drive the positioning rod 501 to move synchronously, so that the right end of the positioning rod 501 separates from the fixing hole 202, thereby unlocking the support shaft 2 and realizing the height adjustment of the scanner body 1.

[0039] When only the scanning angle needs to be adjusted during the use of the scanner body 1, simply rotate the handle 5021. This causes the handle 5021 to move the elastic telescopic rod 604 from one set of positioning holes 603 to the inside of another set of positioning holes 603. During the rotation of the handle 5021, the arc plate 504, which is fixedly connected to the round rod 502, will rotate synchronously. This causes the strip magnetic block 505, which is fixedly installed on the outer arc surface of the arc plate 504, to begin to deflect. It begins to misalign with the magnetic ring 508 installed at the top of the limit rod 507, causing the fixed magnetic block 505 to be deflected. The adjusting block 506 inside the adjusting hole 401 can be unlocked. Then, the first ring 3 is rotated, which will cause the adjusting block 506 to start rotating synchronously. This causes the adjusting block 506 to start pressing against the adjusting hole 401 and move upward, thus compressing the return spring. When the adjusting block 506 moves from one set of adjusting holes 401 to the inside of another set of adjusting holes 401, the adjusting block 506 will be reset under the reaction force generated by the return spring and collide with the adjusting hole 401, making a "click" sound to remind the operator that the adjustment is complete.

[0040] When both scanning height and scanning angle need to be adjusted during the use of the scanner body 1, the handle 5021 can be rotated first to move the elastic telescopic rod 604 from one set of positioning holes 603 to the inside of another set of positioning holes 603. The adjusting block 506 can be unlocked first, and then the handle 5021 can be pulled outward to make the positioning rod 501 start to move laterally, unlocking the support shaft 2. Then the scanning height and scanning angle of the scanner body 1 can be adjusted simultaneously, saving time and speeding up work efficiency.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
