Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a reflective device for a laser pointer. Background Technology

[0002] A laser pointer is an instrument that uses the principle of laser beam orientation to indicate the direction of construction in mine shafts and tunnels. In coal mines, laser pointers are mainly used for directional positioning and precise guidance during tunnel excavation, ensuring that the work proceeds along the designed trajectory, while also adapting to the complex underground environment.

[0003] Coal mines have complex geological conditions, and faults or collapses are frequently encountered during tunnel excavation, requiring the tunnels to change direction. The original laser pointers will become unusable, and new laser pointers need to be installed, or reflective devices can be used to reflect the light emitted by the existing laser pointers.

[0004] The laser pointer reflector includes a reflector and related structures for fixing and adjusting the reflector. For example, patent application number 201821455459.0 discloses a rotating plane reflector for coal mine tunneling. The bottom end of the first vertical connecting rod of this reflector is provided with a first mounting sleeve; the first end of the first horizontal connecting rod passes through the first mounting sleeve, and the second end is provided with a second mounting sleeve; the top end of the second vertical connecting rod passes through the second mounting sleeve, and the bottom end is connected to the horizontal rod of the concave mounting frame; the two vertical rods of the concave mounting frame are provided with threads, and mounting blocks and limiting nuts are sleeved on them; the second horizontal connecting rod passes through the horizontal through hole of the second mounting block, the first end is inserted into the horizontal blind hole of the first mounting block, and the second end is located outside the concave mounting frame and is sleeved with a fastening nut; the plane mirror is provided on the second horizontal connecting rod.

[0005] The reflector can adjust the position and angle of the reflector, but the accuracy of the position and angle of the reflector is low. For example, although it is equipped with a level tube, it lacks adjustment for the levelness of the reflector, and it is not easy to correct when the levelness of the reflector is poor.

There are two L-shaped plates, which are respectively connected to both ends of the clamping strip, forming a groove between the L-shaped plates and the clamping strip. The clamping strip presses on the frame support plate, and the two sides of the upper plate are embedded in the groove. The first tightening screw is threadedly connected to the L-shaped plate and tightens the upper plate.

[0010] Furthermore: the laser pointer reflector includes a second clamping device; the frame support includes a support body and a support shaft located at the center of the support body; the frame includes a frame base plate and a bushing located on the frame base plate, with the bushing fitted onto the support shaft; the second clamping device is connected to the frame support and clamps the edge of the frame base plate.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, the laser pointer reflector includes a mounting frame 1, a leveling structure 2, an upper plate 3, a lens holder plate 4, a lens frame 6, and a reflector assembly 7. The mounting frame 1 includes a mounting frame top plate 11. The upper plate 3 is fixed to the mounting frame top plate 11 via the leveling structure 2, which can adjust the upper plate 3 to a horizontal position and adjust its height. The lens holder plate 4 is placed on and fixed to the upper plate 3, and can move on the upper plate 3 to adjust its position. The lens frame 6 is rotatably connected to the lens holder plate 4, and can rotate horizontally to adjust its direction. The reflector assembly 7 includes a reflector 71 and a horizontally arranged rotating shaft 72. The reflector assembly 7 is rotatably connected to the lens frame 6 via the rotating shaft 72, allowing the reflector 71 to rotate to adjust its direction.

[0025] This invention allows for multiple adjustments to the position and angle of the reflector 71, specifically as follows: 1. The leveling structure 2 allows the upper plate 3 to be adjusted to a horizontal position and its height can be adjusted; 2. The mirror frame support plate 4 can move on the upper plate 3 to adjust its position, thereby adjusting the horizontal position of the reflector 71; 3. The mirror frame 6 is rotatably connected to the mirror frame support plate 4, and rotating the mirror frame 6 adjusts the horizontal angle of the reflector 71; 4. The reflector assembly 7 is rotatably connected to the mirror frame 6 via a horizontally set rotating shaft 72, allowing the reflector 71 to rotate to adjust its vertical angle. These multiple position and angle adjustments ensure that the reflector 71 is in a suitable position and angle, guaranteeing the accuracy of its reflected light direction, thus ensuring that the light accurately achieves functions such as the tunnel excavation direction.

[0026] The specific structure of the leveling structure 2 can be as follows: the upper plate 3 is directly opposite the center of the mounting bracket top plate 11; the leveling structure 2 includes three upper screws 21 and three pull-down components 22. Each upper screw 21 and each pull-down component 22 is evenly distributed around the center of the mounting bracket top plate 11. The upper screws 21 are threaded to the mounting bracket top plate 11 and push the upper plate 3. The pull-down components 22 include a pull-down screw 221, a pull-down nut 223 and a washer assembly 222. The pull-down screw 221 is connected to the upper plate 3 and passes through the mounting bracket top plate 11. The washer assembly 222 is composed of a spherical washer and a conical washer. The washer assembly 222 is fitted on the pull-down screw 221 and placed under the mounting bracket top plate 11. The pull-down nut 223 is threaded to the pull-down screw 221 and presses the washer assembly 222.

[0027] After the laser pointer reflector is installed in the tunnel via mounting bracket 1, it is first leveled. During leveling, an existing bubble level is placed on the upper plate 3, and the direction of the bubble within the level is observed. Then, based on the bubble's direction, the corresponding upper screw 21 is adjusted downwards. The angle of the upper plate 3 changes under its own weight until the bubble in the level is centered. Then, the pull-down nut 223 is tightened to ensure the upper plate 3 is tightly against the upper screw 21, locking the upper plate 3 in place. Simultaneously adjusting the height of each upper screw 21 adjusts the height of the upper plate 3, thereby adjusting the height of the reflector 71. The pull-down screw 221 passes through the top plate 11 of the mounting bracket, limiting significant translation of the upper plate 3. Both spherical and conical washers are existing standard parts, often used in combination to place between two surfaces that are not necessarily parallel.

[0028] As mentioned above, the frame support plate 4 is placed on and fixed on the upper plate 3, and the frame support plate 4 can move on the upper plate 3 to adjust its position. The specific way to achieve this function is as follows: the laser pointer reflector includes a first clamping device 5, which includes a clamping strip 51, an L-shaped plate 52 and a first tightening screw 53. There are two L-shaped plates 52, which are respectively connected to both ends of the clamping strip 51, and a groove is formed between the L-shaped plate 52 and the clamping strip 51. The clamping strip 51 presses on the frame support plate 4, and the two sides of the upper plate 3 are embedded in the groove. The first tightening screw 53 is threadedly connected to the L-shaped plate 52 and tightens the upper plate 3.

[0029] Loosening the first tightening screw 53 will release the pressure strip 51 from the frame support plate 4. Then, the frame support plate 4 can be moved horizontally to a suitable position, and then the pressure strip 51 can be used to tighten the frame support plate 4 again. When the first tightening screw 53 is loosened to release the pressure strip 51 from the frame support plate 4, the frame support plate 4 can also be rotated horizontally.

[0030] The frame 6 is rotatably connected to the frame support plate 4, and the frame 6 can rotate horizontally to adjust its direction. This function can be achieved as follows: the laser pointer reflector includes a second clamping device 8; the frame support plate 4 includes a support body 41 and a support shaft 42 disposed at the center of the support body 41; the frame 6 includes a frame base plate 61 and a bushing 62 disposed on the frame base plate 61, the bushing 62 being fitted onto the support shaft 42; the second clamping device 8 is connected to the frame support plate 4 and clamps the edge of the frame base plate 61.

[0031] Simply loosen the second clamping device 8, and the frame 6 can rotate horizontally; after rotating into position, use the second clamping device 8 to re-clamp the edge of the frame base plate 61.

[0032] The specific structure of the second clamping device 8 can be as follows: The second clamping device 8 includes a guide rod 81, a pressure block 82 and a clamping nut 83. The guide rod 81 is vertically arranged and connected to the support plate body 41. The pressure block 82 is fitted on the guide rod 81 and cooperates with the guide rod 81. The clamping nut 83 is threadedly connected to the guide rod 81 and clamps the pressure block 82.

[0033] To facilitate knowing the specific angle of the frame 6, the following settings can be made: the frame base plate 61 has a first angle scale 611, and the support plate body 41 has an angle indicator line 411 corresponding to the first angle scale 611.

[0034] When installing and adjusting the reflector of the laser pointer, the frame plate 4 can be rotated and moved so that the angle indicator line 411 and the light emitted by the laser pointer are on the same vertical plane. By observing the first angle scale 611 that the angle indicator line 411 points to, the angle between the frame 6 and the vertical plane can be obtained.

[0035] The specific structure of the frame 6 can be as follows: The frame 6 includes a frame stand plate 63 and a scale plate 64. There are two frame stand plates 63, which are spaced apart. The scale plate 64 is connected to one of the frame stand plates 63 and is concentric and perpendicular to the rotating shaft 72. The mirror assembly 7 includes a first shaft end plate 73, a second shaft end plate 75, and a second tightening screw 74. The rotating shaft 72 passes through the two frame stand plates 63 and the scale plate 64. The end plates 75 are connected to both ends of the rotating shaft 72, and the first end plate 73 and the second end plate 75 are respectively attached to the scale plate 64 and the frame stand plate 63. The reflector 71 is located between the two frame stand plates 63 and connected to the rotating shaft 72. The scale plate 64 has a second angle scale 641, and the first end plate 73 has an angle pointer 731 corresponding to the second angle scale 641. The second tightening screw 74 is threaded to the first end plate 73 and tightens the scale plate 64. When the reflector 71 is rotated to the horizontal position, its center line is preferably coaxial with the axis of the support plate shaft 42. When the reflector 71 is rotated to the vertical position, the zero line of the first angle scale 611 is preferably perpendicular to the reflector 71. The center of the reflector 71 is on the same horizontal plane as the axis of the rotating shaft 72.

[0036] Loosen the second tightening screw 74, then rotate the reflector assembly 7 until the reflector 71 is adjusted to the correct angle, and then tighten the second tightening screw 74.

[0037] The specific structure of mounting bracket 1 can be described as follows: Figure 1 , Figure 5 and Figure 6 As shown, the mounting frame 1 includes a lower mounting frame 12, which includes a mounting frame base plate 122 and a connecting rod 121. One end of the connecting rod 121 is threaded to the top plate 11 of the mounting frame, and the other end of the connecting rod 121 is connected to the base plate 122 of the mounting frame. There are three types of lower mounting frame 12: the first type has a straight connecting rod 121, the second type has an L-shaped connecting rod 121, and the third type has a U-shaped connecting rod 121.

[0038] When the connecting rod 121 is straight, the mounting bracket 1 can be installed on the bottom surface of the tunnel. When the connecting rod 121 is L-shaped, the mounting bracket 1 can be installed on the side of the tunnel. When the connecting rod 121 is U-shaped, the mounting bracket 1 can be installed on the top surface of the tunnel. A specific model of mounting bracket 1 can be selected according to actual needs. Mounting holes can be provided on the base plate 122 of the mounting bracket, through which fasteners are passed to install the mounting bracket 1.
