In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-4 The utility model provides an embodiment: a color three-dimensional optical scanner, including a lower base 1. When the lower base 1 is actually used, it can be made of a heavy metal to balance the bottom and improve the stability of the bottom, or the lower base 1 can be fixed by bolts to improve the stability of the bottom structure. The operation can be carried out according to actual needs.

[0024] A secondary seat 2 is fixedly installed at the four corners of the upper surface of the lower base 1 through supporting columns. A servo motor 3 is arranged between the lower base 1 and the secondary seat 2. The bottom end of the servo motor 3 is fixedly installed on the upper surface of the lower base 1. A cross outer cylinder 4 is fixedly installed on the secondary seat 2. The interior of the cross outer cylinder 4 is a hollow cross structure. A threaded screw 5 is arranged at the center position of the cross outer cylinder 4. The bottom end of the threaded screw 5 is fixedly connected to the output shaft of the servo motor 3. A cross inner cylinder 6 is sleeved on the outside of the threaded screw 5. The threaded screw 5 is threadedly connected to the cross inner cylinder 6. The cross inner cylinder 6 is placed inside the cross outer cylinder 4, and the two are slidably connected.

[0025] Through the telescopic structure design of the cross cylinder, the cross inner cylinder 6 can be connected with the cross outer cylinder 4 by limited sliding, so that the cylinder body can be guided and limited by the protruding cross bar, so as to prevent the cross inner cylinder 6 from rotating with the threaded screw 5 when it rotates, thereby ensuring its normal telescopic transmission effect;

[0026] According to the above structure, the servo motor 3 can work. When the servo motor 3 is working, the output shaft of the servo motor 3 synchronously drives the threaded screw 5 to rotate. Since the cross inner cylinder 6 outside the threaded screw 5 is threadedly connected with the threaded screw 5, when the threaded screw 5 rotates, the cross inner cylinder 6 thereon will move up and down (this effect depends on the forward and reverse rotation of the servo motor 3), so that the up and down movement of the cross inner cylinder 6 can drive the structural assembly thereon to move up and down as a whole;

[0027] An extension fixing box 7 is fixedly installed on the top of the cross inner cylinder 6, and an inner insertion rod 8 is movably inserted in the extension fixing box 7;

[0028] In order to position and fix the inner rod 8 inside the extension fixing box 7, threaded holes are provided on the front and back of the extension fixing box 7, and positioning and tightening bolts 9 are threadedly connected in the threaded holes on the front and back of the extension fixing box 7;

[0029] With this structural design, the inner rod 8 can slide left and right in the extension fixing box 7, so that the structure at its end can be linearly adjusted left and right;

[0030] When the inner rod 8 needs to be fixed, the positioning and tightening bolts 9 on the front and back of the extension fixing box can be manually rotated, and the outer wall of the inner rod 8 can be tightened by the positioning and tightening bolts 9 during the rotation process, so as to complete the tightening and fixing work of the inner rod 8;

[0031] Furthermore, in order to prevent the inner rod 8 from falling out of the extension fixing box 7, an end stop ring 10 is fixedly installed at one end of the inner rod 8. The end stop ring 10 can limit one end of the inner rod 8 to prevent the inner rod 8 from falling out of the extension fixing box 7, thereby improving the safety of the structure.

[0032] Furthermore, a fixing seat 11 is fixedly installed at the other end of the inner rod 8, a steering motor 12 is fixedly installed on the lower surface of the bottom end of the fixing seat 11 by bolts, a top end of the output shaft of the steering motor 12 passes through the fixing seat 11 and is fixedly connected to a rotating disk 13, and an optical scanner body 14 is fixedly installed on the upper surface of the rotating disk 13 by bolts;

[0033] With this structural design, the optical scanner body 14 can complete normal three-dimensional optical scanning work. When the working direction of the optical scanner needs to be adjusted, the steering motor 12 can be used to work. When the steering motor 12 is working, it can drive the rotating disk 13 thereon to rotate 360 ​​degrees, so that the optical scanner can be driven to rotate through the rotating disk 13.

[0034] Therefore, the working direction of the optical scanner can be effectively and dynamically steered, and the steering adjustment has a 360° panoramic steering effect, which greatly improves the adjustability of the working surface of the optical scanner, has a large adjustment range, has no adjustment dead angle, has a good use effect, and has excellent performance.

[0035] In this embodiment, a reinforcement ring is fixedly sleeved on the outer wall of the bottom end of the cross outer cylinder 4, and the bottom end of the reinforcement ring is fixedly connected to the secondary seat 2 through a reinforcement column, so that the outside of the cross outer cylinder 4 can be reinforced and protected.

[0036] Working principle: When in use, the adjustment structure and the optical scanner of the utility model are placed in the working area, and the normal three-dimensional optical scanning work can be completed through the optical scanner body 14;

[0037] When the working height of the optical scanner needs to be adjusted, the servo motor 3 can be set to work. When the servo motor 3 is working, it synchronously drives the threaded screw 5 to rotate through its output shaft. Since the cross inner cylinder 6 outside the threaded screw 5 is threadedly connected with the threaded screw 5, when the threaded screw 5 rotates, the cross inner cylinder 6 thereon will move up and down (this effect depends on the forward and reverse rotation of the servo motor 3), so that the up and down movement of the cross inner cylinder 6 can drive the extended fixed box 7 and the top fixed seat 11 to move up and down as a whole, thereby completing the free adjustment effect of the optical scanner in the Y-axis direction, and having the free adjustability of the height after installation;

[0038] When the left and right extension distance of the optical scanner needs to be adjusted, the positioning and tightening bolts 9 on the front and back of the extension fixing box can be manually loosened, so that the optical scanner on the end fixing seat 11 can be driven to move left and right through the provided inner rod 8, so that the optical scanner can be freely adjusted in the X-axis direction, and the working linear extension length can be freely adjusted;

[0039] When the inner rod 8 needs to be fixed, the positioning and tightening bolts 9 on the front and back of the extension fixing box can be manually rotated, and the outer wall of the inner rod 8 can be tightened by the positioning and tightening bolts 9 during the rotation process, so that the inner rod 8 can be tightened and fixed;

[0040] The height of the optical scanner in the Y-axis direction can be freely adjusted through the transmission structure of the thread, and the working extension length of the optical scanner in the X-axis can be freely adjusted through the movable inner rod 8. Through the coordinated use of the two structures, the optical scanner in the installed state can be fully and freely adjusted linearly in the X-axis and Y-axis directions of the two-dimensional plane. It can be applied to different working environments and working requirements, with convenient structural adjustment, high adjustment flexibility, good structural practicality and good use effect.

[0041] When the working direction of the optical scanner needs to be adjusted, the steering motor 12 can be used to work. When working, the steering motor 12 can drive the rotating disk 13 thereon to rotate 360 ​​degrees, so that the optical scanner can be driven to rotate through the rotating disk 13;

[0042] The steering motor provided can drive the optical scanner to perform 360° full-range, no-dead-angle steering adjustment, greatly improving the adjustability of the working surface of the optical scanner. The adjustment range is large, there is no adjustment dead angle, it has good use effect, great structural adjustment flexibility, good use performance, and a simple overall structure with low manufacturing and maintenance costs. It is suitable for promotion and use in this field.

[0043] It is obvious 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 features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
