DETAILED DESCRIPTION

[0025] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0026] In the present disclosure, unless otherwise specified, the directional words such as "up", "down", "left", "right", etc. used to indicate the direction or position relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific directional structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour.

[0027] In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0028] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0029] refer to Figures 1 to 4 As shown, the present disclosure provides a three-dimensional scanning imaging device 4, including a mounting base 10, a connecting frame 20, a locking structure 30 and a scanning module 40. The lower end of the connecting frame 20 is connected to the scanning module 40, the upper end of the connecting frame 20 is formed with a first through hole 21, and the mounting base 10 is formed with a second through hole 11. The locking structure 30 includes a locking rod 31, a reducing assembly 32 and a locking collar 33 that can be unlocked and locked on the locking rod 31. The locking rod 31 is used to be inserted into the first through hole 21 and the second through hole 11. A screwing handle 34 is provided on the outer periphery of the locking collar 33 and the locking collar 33 is locked to the side of the mounting base 10 away from the connecting frame 20. The reducing assembly 32 is configured to increase its outer diameter after passing through the first through hole 21 and the second through hole 11, and abut against the side of the connecting frame 20 away from the mounting base 10.

[0030] When the locking collar 33 is tightened, the locking collar 33 is tightened to the locking lever 31 and the locking collar 33 is tightened to the locking lever 31. When the locking collar 33 is tightened, the locking collar 33 is tightened to the locking lever 31 and the locking collar 33 is tightened to the locking lever 31. When the locking collar 33 is tightened, the locking collar 33 is tightened to the locking lever 31 and the locking collar 33 is tightened to the locking lever 31. When the locking collar 33 is tightened, the locking collar 33 is tightened to the locking lever 31 and the locking collar 33 is tightened to the locking lever 31. When the locking collar 33 is tightened, the locking collar 33 is tightened to the locking lever 31 and the locking collar 33 is tightened to the connecting frame 20.

[0031] Moreover, in the above process, the mounting base 10 and the connecting frame 20 can be fastened together by manually operating the screwing handle 34 without the aid of installation tools, thereby reducing the difficulty of assembly and making it easier for operators to perform assembly and maintenance operations between the mounting base 10 and the connecting frame 20.

[0032] In addition, there may be a plurality of screwing handles 34 , and the plurality of screwing handles 34 are all arranged in a divergent manner in a direction away from the locking collar 33 .

[0033] like Figure 2 As shown, a pull rod 36 may be further provided on the upper portion of the locking collar 33 , so that it is more convenient for the operator to pull the locking rod 31 during the disassembly process.

[0034] The present disclosure does not limit the diameter-changing method and diameter-changing structure of the above-mentioned diameter-changing component 32, as long as the diameter-changing component 32 can have a relatively small outer diameter when entering the first through hole 21 and the second through hole 11, so that the diameter-changing component 32 can smoothly pass through the first through hole 21 and the second through hole 11, so that the portion located outside the first through hole 21 and the second through hole 11 can be larger than the outer diameter of the first through hole 21 and the outer diameter of the second through hole 11, thereby avoiding the problem that the locking rod 31 is out of the first through hole 21 and the second through hole 11 when subjected to axial stress. In an exemplary embodiment provided by the present disclosure, Figures 1 to 2As shown, the reducing assembly 32 may include a first swing arm 321 and a second swing arm 322. The first swing arm 321 and the second swing arm 322 are symmetrically arranged on both sides of the locking rod 31, and the end of the first swing arm 321 close to the locking rod 31 is hinged to the locking rod 31, and the end of the second swing arm 322 close to the locking rod 31 is hinged to the locking rod 31. In this way, before entering the first through hole 21 and the second through hole 11, the first swing arm 321 and the second swing arm 322 can be adjusted to the side close to the locking rod 31. At this time, the dimensions of the first swing arm 321 and the second swing arm 322 in the radial direction of the locking rod 31 are smaller, thereby avoiding the problem of interference between the first swing arm 321 and the second swing arm 322 and the hole wall of the first through hole 21 and the hole wall of the second through hole 11 during the process of inserting the locking rod 31 into the first through hole 21 and the second through hole 11; As the locking rod 31 is continuously inserted, when the first swing arm 321 and the second swing arm 322 move to the outside of the second through hole 11, the first swing arm 321 and the second swing arm 322 can be adjusted in the direction away from the locking rod 31, so that the first swing arm 321 and the second swing arm 322 have a larger size in the radial direction of the locking rod 31, thereby stopping the connecting frame 20 to avoid the locking rod 31 from falling out of the first through hole 21 and the second through hole 11 when subjected to axial stress of the locking rod 31.

[0035] In other embodiments provided in the present disclosure, telescopic rods can be provided on both sides of the locking rod 31 to achieve the abutment with the connecting frame 20. Specifically, the reducing assembly 32 includes a first telescopic rod and a second telescopic rod. Before the reducing assembly 32 enters the first through hole 21 and the second through hole 11, the first telescopic rod and the second telescopic rod can be adjusted to a retracted state. At this time, the first telescopic rod and the second telescopic rod will not affect the locking rod 31 from entering the first through hole 21 and the second through hole 11. After the reducing assembly 32 extends from the first through hole 21 and the second through hole 11, the first telescopic rod and the second telescopic rod are adjusted to an extended state. At this time, under the limiting action of the first telescopic rod and the second telescopic rod, the relative locking between the locking rod 31 and the connecting frame 20 can be achieved.

[0036] In order to further avoid the above locking rod 31 from being inserted into the first through hole 21 and the second through hole 11, Figure 2As shown, the first swing arm 321 and the second swing arm 322 interfere with or interfere with the inner wall of the first through hole 21 and the inner wall of the second through hole 11. In an exemplary embodiment provided in the present disclosure, the locking rod 31 may be formed with a first groove 311 and a second groove 312. The first groove 311 is arranged corresponding to the first swing arm 321 and is used to accommodate the first swing arm 321. The second groove 312 is arranged corresponding to the second swing arm 322 and is used to accommodate the second swing arm 322, so that the first swing arm 321 and the second swing arm 322 do not protrude from the outer wall of the locking rod 31. In this way, before the above-mentioned locking rod 31 is passed through the first through hole 21 and the second through hole 11, the first swing arm 321 can be completely received in the first groove 311 and the second swing arm 322 can be completely received in the second groove 312. The first swing arm 321 and the second swing arm 322 will not protrude from the locking rod 31, thereby effectively avoiding interference or interference between the first swing arm 321 and the second swing arm 322 and the inner wall of the first through hole 21 and the inner wall of the second through hole 11.

[0037] Alternatively, as Figure 2 As shown, the locking rod 31 includes a threaded section 313, a reducing section 314, and a guide section 315. The reducing section 314 is connected between the threaded section 313 and the guide section 315. The threaded section 313 is formed with external threads. The locking collar 33 is threadedly connected to the threaded section 313. The reducing assembly 32 is disposed on the reducing section 314. The diameter of the guide section 315 gradually decreases in a direction away from the reducing section 314. The gradually decreasing diameter of the guide section 315 in a direction away from the reducing section 314 makes it easier to insert the locking rod 31 into the first through hole 21, thereby reducing the difficulty of assembling the locking rod 31.

[0038] In order to enable the first swing arm 321 and the second swing arm 322 to be quickly and automatically deployed after the end of the locking rod 31 passes through the second through hole 11, in an embodiment provided by the present disclosure, Figure 2 As shown, the locking structure 30 further includes an elastic member 35, which is used to drive the first swing arm 321 to rotate in a direction away from the first groove 311, and the elastic member 35 is used to drive the second swing arm 322 to rotate in a direction away from the second groove 312. By providing the elastic member 35, after the locking rod 31 is inserted into the first through hole 21 and the second through hole 11, the elastic action of the elastic member 35 can automatically lift the first swing arm 321 and the second swing arm 322, so that the first swing arm 321 and the second swing arm 322 automatically abut against the side wall of the connecting frame 20, thereby limiting the connection frame 20 and the mounting base 10.

[0039] In an exemplary embodiment provided by the present disclosure, optionally, as Figure 2As shown, the elastic member 35 is a spring column, an open groove 3150 is formed inside the guide section 315, and a connecting rod 3151 protruding toward the open groove 3150 is formed at one end of the reducing section 314 close to the guide section 315. One end of the spring column is connected to the bottom wall of the open groove 3150, and the other end of the spring column is connected to the connecting rod 3151. The spring column is in a pre-stressed state when the first swing arm 321 is accommodated in the first groove 311 and the second swing arm 322 is accommodated in the second groove 312. In this way, when the locking rod 31 is assembled in the first through hole 21 and the second through hole 11, the first swing arm 321 and the second swing arm 322 can be first received in the first groove 311 and the second groove 312. At this time, the spring column is in a pre-compressed state. When the reducing assembly 32 passes through the second through hole 11, the spring column acts to drive the first swing arm 321 to automatically disengage from the first groove 311 and the second swing arm 322 to automatically disengage from the second groove 312, so that the first swing arm 321 and the second swing arm 322 respectively abut against the connecting frame 20.

[0040] Similarly, when disassembling the above-mentioned mounting base 10 and the connecting frame 20, the locking ring 33 can be removed first, and the locking rod 31 can be pushed downward until the first swing arm 321 and the second swing arm 322 are detached from the connecting frame 20. Then, the first swing arm 321 and the second swing arm 322 are pressed to embed the first swing arm 321 in the first groove 311 and the second swing arm 322 in the second groove 312. When the locking rod 31 is lifted, the locking rod 31 together with the above-mentioned reducing assembly 32 can be removed from the first through hole 21 and the second through hole 11.

[0041] Optionally, the scanning module 40 is rotatably connected to the connecting frame 20. During the scanning process of the scanning module 40 scanning and imaging the material, since the scanning module 40 is rotatably connected to the connecting frame 20, 360° scanning can be achieved by rotating the scanning module 40, reducing the scanning blind spot, thereby adapting to different working scenarios.

[0042] The present disclosure does not limit the rotatable connection method and connection structure between the scanning module 40 and the connecting frame 20. For example, in an embodiment provided by the present disclosure, Figure 3 As shown, the 3D scanning imaging device 4 further includes a rotary motor 50, which is mounted on the connecting frame 20. A rotating shaft 51 of the rotary motor 50 protrudes from the connecting frame 20, and the scanning module 40 is connected to the rotating shaft 51 of the rotary motor 50. When the rotating shaft 51 of the rotary motor 50 rotates, it drives the scanning module 40 connected to the rotary motor 50 to rotate axially around the rotating shaft 51, thereby achieving multi-angle scanning operations.

[0043] Alternatively, in another embodiment provided herein, the scanning module 40 may be driven to rotate by gear transmission, worm gear transmission, or the like.

[0044] In order to facilitate the connection between the rotating shaft 51 of the rotating motor 50 and the bracket of the scanning module 40, as shown in FIG. Figure 1 、 Figure 3 As shown, the above-mentioned three-dimensional scanning imaging device 4 can also include a connecting block 60, that is, the rotating shaft 51 and the scanning module 40 are respectively connected to the two sides of the connecting block 60. When the rotating shaft 51 rotates, it can drive the scanning module 40 connected to the connecting block 60 to rotate synchronously.

[0045] Alternatively, as Figure 1 、 Figure 3 As shown, the scanning module 40 includes a camera 41 and a lens protection cover 42. The lens protection cover 42 is detachably attached to the camera 41. Thus, when scanning of materials is required, the lens protection cover 42 can be removed from the camera 41. After scanning of the materials is completed, the lens protection cover 42 can be replaced on the camera 41 to prevent the camera 41 from being disturbed or interfered with by external devices, floating objects, and other impurities.

[0046] In an exemplary embodiment provided by the present disclosure, the camera 41 and the lens protection cover 42 may be connected by a snap-fit ​​method, such as Figure 4 As shown, the outer wall of the camera 41 is formed with one of a slot 410 and a block 420, and the lens protective cover 42 is formed with the other of the slot 410 and the block 420. The block 420 is used to engage with the slot 410. During the connection process between the camera 41 and the lens protective cover 42, the block 420 can be engaged with the slot 410 to lock the lens protective cover 42 to the camera 41, thereby achieving relative fixation between the two. The lens protective cover 42 can also be detached from the camera 41 by rotating or pulling without the need for removal tools, thus having the advantages of simple structure and easy disassembly.

[0047] In another embodiment provided by the present disclosure, the camera 41 and the lens protection cover 42 can also be connected by means of threads. Specifically, a first external thread is formed on the outer peripheral surface of the camera 41, and a first internal thread is formed on the inner peripheral surface of the lens protection cover 42. In this way, with the cooperation of the first external thread and the first internal thread, the lens protection cover 42 can be locked on the camera 41 by screwing.

[0048] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0050] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
