DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5As shown, an embodiment of the utility model provides a laser three-dimensional scanner, which includes a scanner lens 1, a fill light structure and a switching structure. A fixing ring 2 is fixed to the outer side of the scanner lens 1. The fill light structure is rotatably connected to the fixing ring 2 through two switching structures. The fill light structure includes a plurality of fill light lamps 102. The plurality of fill light lamps 102 are distributed on one side of the camera end of the scanner lens 1 along the circumference of the fixing ring 2. The switching structure includes a second switching portion sleeved on the outer periphery of the fixing ring 2 and two first switching portions symmetrically distributed on both sides of the outer periphery of the second switching portion along the radial direction of the fixing ring 2. The first switching portion is connected to the fill light structure. The first switching portion and the second switching portion can be relatively rotatably arranged to adjust the angle between the axis of the fill light structure and the axis of the scanner lens 1.

[0028] In this embodiment, the fill light 102 of the fill light structure is used to fill light the reflective points of the object to be measured in the mine cave, which effectively improves the light environment of the reflective points in the mine cave, thereby avoiding the situation where the detection effect of the laser three-dimensional scanner is affected, and improving the detection effect and reliability. On the other hand, compared with the situation in the prior art where the fill light direction of the fill light is always parallel to the detection direction of the scanner lens 1, the laser three-dimensional scanner in this embodiment can realize the relative rotation of the fill light structure and the scanner lens 1 through the relative rotation of the first adapter and the second adapter, and then adjust the angle between the axis of the fill light structure and the axis of the scanner lens 1, so as to realize the convenient adjustment of the fill light angle and improve the applicability of the laser three-dimensional scanner. Furthermore, the fill light structure in this embodiment is not directly in contact with the fixing ring 2 of the scanner lens 1, which is more conducive to the rotation of the fill light structure relative to the scanner lens 1, and improves the convenience of adjusting the fill light angle.

[0029] It can be understood that the first adapter part and the second adapter part have a relative rotation center line extending radially along the fill light structure and the scanner lens 1, and the two adapter structures are symmetrically arranged so that the two relative rotation center lines of the two adapter structures are coaxial, and the two coaxial relative rotation center lines can both serve as the relative rotation center lines of the scanner lens 1 and the fill light structure.

[0030] like Figures 1 to 5 As shown, the first adapter part includes a connecting block 301, a first connecting rod 307 and a rotating block 306 which are fixedly connected in sequence along the radial direction of the outer periphery of the scanner lens 1 toward the axis, the connecting block 301 is fixedly connected to the fill light structure, the second adapter part has a rotating groove on one side corresponding to the first adapter part, and a limiting step is provided on the side of the rotating groove close to the opening, the rotating block 306 and at least a part of the first connecting rod 307 are rotatably arranged in the rotating groove relative to the second adapter part, and the rotating block 306 cooperates with the limiting step stopper.

[0031] In this embodiment, the first connecting rod 307 and the rotating block 306 are both cylindrical structures, and the rotating groove is a cylindrical groove adapted to the rotating block 306 and the first connecting rod 307. The axes of the rotating groove, the first connecting rod 307 and the rotating block 306 coincide and are the rotating center line. By setting the rotating groove, the first connecting rod 307 and the rotating block 306 can be rotated and accommodated, and the reliability of the relative rotation between the first adapter and the second adapter is ensured. On the other hand, by setting the limiting step, the rotating block 306 is prevented from falling out of the rotating groove, and the reliability and stability of the connection between the first adapter and the second adapter are ensured.

[0032] like Figure 3 and Figure 5 As shown, the rotation groove includes a rotation opening groove section and a rotation accommodating groove section 305 connected to each other, the rotation opening groove section is located on the side of the rotation accommodating groove section 305 facing the connecting block 301 and has an inner diameter smaller than the rotation accommodating groove section 305, a limiting step is formed between the outer walls of the rotation opening groove section and the rotation accommodating groove section 305, the first connecting rod 307 is rotatably arranged in the rotation opening groove section and has an outer diameter that matches the inner diameter of the rotation opening groove section, and the connecting block 301 is rotatably arranged in the rotation accommodating groove section 305 and has an outer diameter that matches the inner diameter of the rotation accommodating groove section 305. This arrangement facilitates the processing of the limiting step and the limiting of the rotation block 306, prevents the rotation block 306 from falling out, and ensures the reliability and stability of the rotation connection between the first adapter and the second adapter.

[0033] Specifically, the first adapter portion also includes a limiting structure consisting of an elastic member 309 and a limiting block 310. The rotating block 306 is provided with a groove 308 on its outer periphery in the rotation direction. The limiting block 310 is slidably arranged in the groove 308. The two ends of the elastic member 309 are respectively connected to the bottom wall of the groove 308 and the end of the limiting block 310 located in the groove 308, so that the end face of the limiting block 310 facing away from the elastic member 309 abuts against the inner wall of the rotating groove. The inner wall of the rotating groove is provided with a limiting groove 311. The limiting groove 311 is a spherical groove or an arc groove extending along the rotation direction of the rotating block 306. The shape of the end face of the limiting block 310 facing away from the elastic member 309 is adapted to the limiting groove 311. The end face of the limiting block 310 facing away from the elastic member 309 protrudes or extends into the groove 308 as the rotating block 306 rotates and is separably limited and matched with the limiting groove 311.

[0034] In this way, the rotation of the rotating block 306 can be limited by the cooperation between the limiting block 310 and the limiting groove 311, which is helpful to prevent the rotating block 306 from self-rotating. On the other hand, by limiting the shape of the limiting groove 311 and the end surface shape of the limiting block 310, it is helpful for the limiting block 310 to rotate into or out of the limiting groove 311 during the relative rotation of the limiting block 310 and the limiting groove 311, avoiding the relative rotation of the first adapter and the second adapter being stuck due to the inability of the limiting block 310 to rotate out of the limiting groove 311, thereby ensuring the reliability and stability of the angle adjustment of the scanner lens 1 and the fill light structure.

[0035] like Figure 5 As shown, there are a plurality of limiting grooves 311, and the plurality of limiting grooves 311 are distributed on the inner wall of the rotating groove along the rotating direction of the rotating block 306. In this arrangement, by providing a plurality of limiting grooves 311, when the rotating block 306 rotates in the rotating accommodating groove section 305, the limiting block 310 can be inserted into one of the plurality of limiting grooves 311, thereby improving the limiting effect on the rotating block 306.

[0036] In this embodiment, when the rotating block 306 is in the rotating accommodating groove section 305 and the two rotate relative to each other, the limit block 310 located in the limit groove 311 will gradually separate from the limit groove 311 under the action of rotation and be gradually pressed into the groove 308. After the limit block 310 is completely separated from the limit groove 311, it will abut against the inner wall of the rotating accommodating groove section 305 where the limit groove 311 is not provided, until the limit block 310 corresponds to the next limit groove 311 in the rotation direction as the rotating block 306 and the rotating accommodating groove section 305 rotate relative to each other. The limit block 310 will be inserted into the next limit groove 311 under the elastic action of the elastic member 309 and be re-positioned and fixed. Such a configuration is conducive to limiting the relative rotation of the rotating block 306 and the rotating accommodating groove section 305 to different positions, and further realizing the limitation of the axis of the scanner lens 1 and the axis of the fill light structure when they are rotated to different angles, so that the angular rotation adjustment of the scanner lens 1 and the fill light structure is more stable and reliable, and prevents the situation in which the angle between the axis of the scanner lens 1 and the axis of the fill light structure rotates relative to each other when the angle is adjusted to the required angle, thereby improving the reliability and stability of the laser three-dimensional scanner during use.

[0037] like Figure 5 As shown, in this embodiment, the number of the limiting structures is at least two, the number of the grooves 308 corresponds to the number of the limiting structures, and the plurality of limiting structures are equidistantly distributed along the rotation direction of the rotating block 306. This arrangement is conducive to further improving the stability and reliability of the angle rotation adjustment of the scanner lens 1 and the fill light structure.

[0038] like Figures 1 to 4As shown, the second adapter portion includes a circular ring 202 and two adapter components. The two adapter components are symmetrically distributed on both sides of the inner side of the circular ring 202 along the radial direction of the fixed ring 2 and are respectively connected to the two first adapter portions. The adapter component includes a rotating block 3 and a second connecting rod 203. The circular ring 202, the rotating block 3 and the second connecting rod 203 are fixedly connected in sequence along the outer periphery of the scanner lens 1 in the radial direction toward the axis. The rotating block 3 is rotatably connected to the first adapter portion. An annular groove extending along the circumference of the fixed ring 2 is provided on the outer periphery of the fixed ring 2. The circular ring 202 and at least part of the second connecting rod 203 can be slidably arranged in the annular groove along the extension direction of the annular groove. Specifically, the annular groove includes an annular opening groove section 204 and an annular receiving groove section 201 which are connected to each other. The annular opening groove section 204 is located on the side of the annular receiving groove section 201 facing the rotating block 3 and has an inner diameter smaller than the annular receiving groove section 201. The second connecting rod 203 is rotatably inserted into the annular opening groove section 204 and its size is adapted to the size of the annular opening groove section 204. The ring 202 is rotatably arranged in the annular receiving groove section 201 and its size is adapted to the size of the annular receiving groove section 201.

[0039] In this embodiment, the rotating block 3 has a rotating groove matched with the first adapter, the circular ring 202 is rotatably connected in the rotating groove, the circular ring 202 is rotatably set in the annular accommodating groove section 201, the second connecting rod 203 is slidably connected in the annular opening groove section 204, and one end of the second connecting rod 203 extending out of the annular groove (annular opening groove section 204) is fixedly connected to the side of the rotating block 3 away from the connecting block 301. By setting the annular groove and dividing the annular groove, the installation limit and rotation guide of the circular ring 202 and the second connecting rod 203 are realized, the reliability of the second adapter rotating around the outer circumference of the fixed ring 2 is ensured, and then the reliability and stability of the fill light structure rotating around the outer circumference of the scanner lens 1 are ensured, which is conducive to ensuring the fill light effect, and in this way, the angle between the axis of the fill light structure and the axis of the scanner lens 1 can be combined with the rotation adjustment, so as to further improve the adjustment of the fill light angle of the fill light 102 and improve the fill light effect.

[0040] like Figure 3 As shown, the second adapter also includes a first magnet ring 205 and a second magnet ring 206. The first magnet ring 205 is arranged in the bottom wall of the annular groove, and the second magnet ring 206 is arranged in the end surface of the circular ring 202 facing the bottom wall of the annular groove. The first magnet ring 205 and the second magnet ring 206 are attracted to each other.

[0041] In this embodiment, the first magnet ring 205 is overlapped with the second magnet ring 206. The first magnet ring 205 and the second magnet ring 206 are magnets of the same type and made of the same material. The first magnet ring 205 and the second magnet ring 206 attract each other with opposite poles. When the circular ring 202 rotates, the second magnet ring 206 is driven to move synchronously. After the circular ring 202 rotates in the annular accommodating groove section 201, the circular ring 202 can be fixed by the attraction between the opposite poles of the first magnet ring 205 and the second magnet ring 206.

[0042] like Figures 1 to 3 As shown, the fill light structure also includes an annular fill light frame 101 and two mounting blocks 103. The mounting blocks 103 and the fill light 102 are respectively arranged on both sides of the annular fill light frame 101 in the axial direction, and the fixing ring 2 is fixedly connected to the corresponding mounting blocks 103 through the adapter structure. This arrangement facilitates the fixed connection between the annular fill light frame 101 and the two first adapters.

[0043] Specifically, the end of the mounting block 103 away from the annular fill light frame 101 has a threaded hole 104 , and the first adapter portion includes a connecting block 301 , which is inserted into the mounting block 103 and fixedly connected by rotating the bolt 303 .

[0044] In this embodiment, a plurality of fill light lamps 102 distributed along the circumference of the annular fill light frame 101 are installed on one side of the annular fill light frame 101, and two mounting blocks 103 symmetrically distributed in the upper and lower directions are fixed on the side of the annular fill light frame 101 away from the fill light lamps 102. The connecting block 301 of the first adapter has a mounting groove 302, and one end of the mounting block 103 is correspondingly inserted into the mounting groove 302 of the connecting block 301 on the corresponding side. The laser three-dimensional scanner also includes a fastener. The fastener in this embodiment is a rotating bolt 303. The connecting block 301 has a through hole 304 provided corresponding to the threaded hole 104. One end of the rotating bolt 303 is inserted into the through hole 304 opened in the connecting block 301, and one end of the rotating bolt 303 extending out of the through hole 304 is screwed into the threaded hole 104 opened in the mounting block 103 to fix the mounting block 103 and the corresponding connecting block 301.

[0045] In summary, the embodiment of the utility model provides a laser three-dimensional scanner, and its implementation principle is: by adopting a fill light mechanism, the mounting block 103 on one side of the annular fill light frame 101 is inserted into the mounting groove 302 opened in the connecting block 301, and then the rotating bolt 303 on one side of the connecting block 301 is rotated, so that one end of the rotating bolt 303 is screwed into the threaded hole 104, and the mounting block 103 can be fixed in the mounting groove 302 by screwing the rotating bolt 303 and the threaded hole 104, so that the annular fill light frame 101 is installed on the scanner lens 1. The fill light 102 on the annular fill light frame 101 can be used to fill light the reflective points of the object to be measured in the mine cave, effectively improving the light environment of the reflective points in the mine cave, thereby avoiding the detection effect of the laser three-dimensional scanner being affected. And through the cooperation of the rotating block 306 and the first connecting rod 307, the connecting block 301 and the annular fill light frame 101 can be relatively rotated to adjust the angle between the axis of the fill light structure and the axis of the scanner lens 1, so as to adjust the fill light angle. At the same time, the annular fill light frame 101 is not in direct contact with the scanner lens 1, so that the annular fill light frame can rotate more freely, and then the fill light angle of the fill light lamp 102 can be adjusted, further improving the fill light effect of the fill light lamp 102.
